Efficacy of arthroscopy in the treatment of lateral epicondylitis: a systematic review with meta-analysis

Lateral epicondylitis, popularly known as tennis elbow, has a high incidence in athletes, around 50%, with a high prevalence in beginners learning the one-handed backhand. It is a clinical orthopaedic condition with a major impact on public health due to its high frequency in manual workers, 10.5% of whom may have lateral elbow pain and 2.4% of whom have a confirmed diagnosis. The aim of this study is to compare the effectiveness of arthroscopic versus non-arthroscopic techniques (open and percutaneous). This is a systematic review with meta-analysis. There is no need for approval by the ethics committee or institutional scientific review board. The reference lists of the included and previously published articles were searched for more relevant studies that met the eligibility criteria. Based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Five articles were selected containing patients diagnosed with lateral epicondylitis who underwent surgical treatment by arthroscopy, open surgery and/or percutaneous surgery. A total of 544 patients were included, with a mean age of 46 years. Of these, 347 were treated by arthroscopy, 81 by open surgery and 42 by percutaneous surgery. The results were analyzed using the DASH (Disabilities of the arm, shoulder and hand) score, which assesses dysfunctions of the arm, shoulder and hand. In addition, some studies analyzed the VAS (Visual Analogue Scale) index, patient satisfaction, complications and other clinical assessment scales.Arthroscopic, open and percutaneous surgeries proved to be effective methods for treating lateral epicondylitis.However, because arthroscopy is a method that allows a complete intra-articular evaluation and adequate release of the tendons without ligament involvement, it was associated with a better prognosis in terms of pain, limb mobility and consequent patient satisfaction when compared to open and percutaneous procedures.

Reduction of the Douleur Neuropathique 4 (DN4) Score in the Supraclavicular Nerve Separation and Disability of the Arm Shoulder and Hand (DASH) Score Third Month and Sixth Month Post Open Reduction Internal Fixation of Clavicular Fracture

Introduction: Clavicle fractures are common injuries to the scapular girdle, with fractures in the middle third of the clavicle being the most prevalent. Non-operative treatment is often used but can lead to unsatisfactory outcomes, including pain, malunion, and thoracic outlet syndrome. As a result, operative fixation using Open Reduction and Internal Fixation (ORIF) Plate and Screw (ORIF PS) has gained popularity. Postoperative complications such as numbness around the surgical incision are frequently observed. This study aims to evaluate the differences in functional outcomes in patients with clavicle fractures post ORIF PS using the preserved supraclavicular nerve and non-preserved supraclavicular nerve methods, assessed by the Disability of the Arm Shoulder and Hand (DASH) score and Douleur Neuropathique 4 (DN4) score at 3 and 6 months post-operation. Methods: This cohort study used medical records data from patients with middle third clavicle fractures at RSUP Prof. Dr. IGNG Ngoerah. Patients were divided into two groups: preserved supraclavicular nerve and non-preserved supraclavicular nerve. Data were collected at 3 and 6 months post-operation to evaluate DASH and DN4 scores. Statistical analysis was performed using SPSS version 25.0, with the Kolmogorov-Smirnov test for normality and appropriate hypothesis tests based on data distribution. Results: This study involved 51 patients with clavicle fractures undergoing ORIF PS surgery. There were no significant differences in baseline characteristics between the two groups. At three months, the difference in DN4 scores between the preserved and non-preserved groups was not statistically significant (p=0.347). However, at six months, the preserved group showed significantly lower DN4 scores (p=0.012). The DASH scores at three months showed a significant difference between the two groups (p<0.001), with the preserved group showing better scores. At six months, the difference in DASH scores was not significant (p=0.210). Longitudinal analysis showed significant reductions in DASH and DN4 scores between three and six months in both groups. Discussion: This study demonstrates that preserving the supraclavicular nerve during ORIF clavicle surgery provides significant benefits in reducing neuropathic pain and improving arm function in the long term. These findings support the importance of this approach in clavicle fracture surgeries to reduce complications and enhance functional outcomes. Conclusion: Preserving the supraclavicular nerve during ORIF clavicle surgery can significantly reduce neuropathic pain and improve arm function in the long term. These findings emphasize the importance of this approach in clinical practice to improve patient outcomes following clavicle fracture surgery. Keywords: Clavicular fracture, Douleur Neuropathique 4 score, supraclavicular nerve separation, DN4 score, DASH score, ORIF.

Clinical Observations of the Effectiveness of the Masquelet Induced Membrane Technique in the Treatment of Critical Long-Bone Defects of the Lower and Upper Extremities.

Background and Objectives: Successful treatment of severe trauma and fractures of the long bones with successful healing and bone union is still a significant challenge for surgeons. Unfortunately, up to 10% of long-bone fractures develop bone healing disorders. The aim of this study was to evaluate the results of treating bone defects with different etiologies in the upper and lower extremities using the induced membrane technique. Materials and Methods: We prospectively evaluated the radiological and clinical outcomes of 45 patients with severe bone defects treated with the induced membrane technique during the period from May 2021 to October 2023. The time to bone defect regeneration, size of the bone defect, and the cost of treatment were evaluated. Functional outcomes were assessed using the Disabilities of the Arm Shoulder and Hand (DASH) scale, SF-36, and the Lower Limb Functional Index (LLFI). Results: The mean follow-up time was 31 months (12-35). There were 20 patients with upper extremity bone defects and 25 with lower extremity bone defects. The mean defect length was 7.9 cm for the upper extremity (3.5-18) and 5.3 cm for the lower extremity (3-11). The mean times to achieve bone union and remodeling were 6.0 months (3-12) and 9 months (3-13) for the upper and lower limbs, respectively. Clinical evaluation at the end of treatment (achieving bone union) showed statistically significant improvements in the DASH, SF-36, and LLFI scales for pre- and postoperative outcomes. There was no statistical significance in the SF-36 clinical scale scores after surgical treatment compared to reconstructive treatment of upper and lower extremity bone defects. Results: The presented reconstructive approach to the treatment of bone defects and healing disorders and extensive analysis demonstrate the effectiveness of the induced membrane technique in a short follow-up period, with a relatively high level of patient comfort and good clinical results in the treatment of severe bone defects with particularly infectious etiologies.

The effect of plate location on radial nerve palsy recovery time associated with humeral shaft fractures.

This study aims to investigate the influence of plate placement on nerve regeneration in humerus fractures accompanied by radial nerve injury. A retrospective analysis was conducted on a cohort of 94 patients with humerus fractures and concomitant radial nerve injury treated between January 2018 and November 2022. After applying exclusion criteria, 31 patients were included in the study. Clinical outcomes were assessed by comparing demographic data, surgical duration, radial nerve recovery time, the Mayo Elbow Performance Score (MEPS), Disabilities of the Arm Shoulder and Hand (DASH), and the Medical Research Council (MRC) scale. Two distinct groups were established: lateral plating and anteromedial (AM) plating. These groups demonstrated comparability regarding age, gender, and body mass index (BMI). No statistically significant differences were observed between the groups concerning MEPS and MRC. The AM plating group notably exhibited shorter surgical durations, faster recovery times, and lower DASH scores. According to the findings of this investigation, in cases of humerus fractures accompanied by radial nerve injury, AM plating may be preferable over lateral plating due to its association with reduced surgical durations and expedited nerve recovery.

ЭФФЕКТИВНОСТЬ ВЫПОЛНЕНИЯ РЕЛИЗА НАДЛОПАТОЧНОГО НЕРВА ПРИ АРТРОСКОПИЧЕСКОМ ВЫПОЛНЕНИИ ШВА ПРИ РАЗРЫВЕ СУХОЖИЛИЯ НАДОСТНОЙ МЫШЦЫ

Supraspinatus injuries may be associated with traction injury to the suprascapular nerve, potentially responsible for rotator cuff pain or weakness and as a consequence have an impact on early recovery from tendon suture. Purpose: to study the results of release of the suprascapular nerve in the superior notch of the scapula during arthroscopic repair surgery of the supraspinatus tendon of the shoulder joint depending of the extent of damage. Materials and methods: The study included 121 patients. The patients were divided into 2 groups. Group A consisted of patients who underwent arthroscopic repair of the supraspinatus tendon. Group B included patients who underwent the same operation with additional release of the suprascapular nerve in the superior notch of the scapula. An assessment was made before surgery using the DASH (Disabilities of the Arm, Shoulder and Hand) and VAS (visual analogue scale) scales, and then at 1, 6, 12 months after surgery and the degree of dystrophy according to the Goutallier classification in T1-weighted MRI before surgery, and then 3, 6, 12 months after surgery. Results: The difference between the groups according to Goutalier classification in the third month after surgery was 0.04, according to the VAS assessment in the first month after surgery was p < 0.01, and at the same period a statistically significant difference was found in the DASH assessment (p = 0.01). Discussion: There are conflicting results regarding the issue being studied. This is explained by the lack of knowledge of pathophysiological processes in this area, as well as the high level of evidence of published studies. Conclusion: Additional release of the supraspinatus nerve in the scapular notch during repair of the supraspinatus muscle is effective in the early stages of recovery, and is also of greatest importance in cases of massive tears.

Displaced humeral shaft fractures: Assessment of fracture union and complications following dual plate fixation using an anterior approach

The humeral bone is subject to torsional forces. In case of displaced shaft fractures, internal fixation remains the standard of care. This retrospective two-center study assessed the fracture union rate and complications after dual 3.5 mm locking compression plate (LCP) fixation using an anterolateral approach. Over a 9-year period, 38 patients underwent surgery in two centers. They had a mean age of 53.7 years (15–97, ± standard deviation (SD) 26) and there were three open fracture cases (7.9 %). The dominant side was affected in 21 cases (55.3 %) and there were 11 polytrauma patients (29 %). Mean operative time was 78 min (40–124, ± 19.8 SD). Patients were treated with dual 3.5 mm LCP fixation (6 screws on either side of the fracture line, anterolateral approach without a tourniquet). The first two orthogonal views showing at least 3 cortical bridges out of 4 determined fracture healing, as assessed by two independent raters. Pre- and postoperative complications were tabulated. Clinical outcomes included range of motion (ROM) and return to activities, while functional outcomes were assessed with the Disability of the Arm Shoulder and Hand (DASH), the Constant score, the Subjective Shoulder Score (SSV) and the Mayo Elbow Performance Score (MEPS). Minimum follow-up was 1 year. Four patients were given a shoulder immobilizer to wear for 3 weeks; immediate mobilization was the standard of care for the other patients. Fracture union was achieved in all cases within a mean of 11.7 weeks (6–28 ± 7.1 SD) without any heterotopic ossification of the brachialis muscle. There were eight patients with preoperative radial nerve palsy and two cases of postoperative palsy. There was one surgical site infection (2.6 %). Return to work for active patients was possible in 87 % of cases within a mean of 23 weeks (6–72 ± 11 SD). The Constant score was 84.6 (35–100, ± 13.4 SD), the SSV score was 80.7 (60–100, ± 8.2 SD), the DASH score was 13.5 (0–38.3, ± 8.8 SD) and the MEPS score was 85 (55–100, ± 11.9 SD). Traditional fixation methods provide little control over torsional forces, leading to non-union rates between 3 % and 12 % and delayed union (12 to 20 weeks). The simplicity of the technique described here, and the short operative time, may help explain the low infection rate. Dual plate fixation makes it possible to use more screws and allows nerve exploration and decompression in case of preoperative nerve palsy. Dual plate fixation to treat humeral shaft fractures is a simple and reliable technique.

Comparison of Locking Plate Alone and Locking Plate Combined with 3D Printed Polymethylmethacrylate Augmentation in Treating Proximal Humerus Fractures in the Elderly

BackgroundLocking plates are widely used in open reduction internal fixation (ORIF) for proximal humeral fracture (PHF). However, the optimal surgical treatment of unstable, displaced PHF in elderly patients remains controversial. This study aimed to compare the radiological and clinical outcomes of surgical treatment of PHF in the elderly with locking plate (LP) alone and locking plate combined with 3D printed polymethylmethacrylate (PMMA) prosthesis augmentation (LP-PA). MethodsFrom May 2015 to April 2021, a total of 97 patients aged ≥ 60 years with acute unstable PHF who underwent osteosynthesis with either LP (46 patients) or LP-PA (51 patients) were retrospectively analyzed. For the LP-PA group, a customized proximal humeral prosthesis made of PMMA cement was intra-operatively fabricated by a three-dimensional (3D) printed prototype mold for the humeral medial support. Radiological outcomes were analyzed by measuring the value of neck-shaft angle (NSA) and humeral head height (HHH). The clinical outcomes were evaluated using Constant-Murley Score (CMS), Disabilities of the Arm Shoulder and Hand (DASH) score, American Shoulder and Elbow Surgeons (ASES) score, and the shoulder range of motion (ROM). Pain was measured using a visual analogue scale (VAS). ResultsAt the one-year follow-up, all fractures healed radiologically and clinically. The mean changes of NSA and HHH over the follow-up period were markedly smaller in the LP-PA group (3.8 ± 0.9° and 1.7 ± 0.3 mm) than those in the LP group (9.7 ± 2.1° and 3.2 ± 0.6 mm, both P < 0.0001). The LP-PA group also presented lower DASH score (17.1 ± 3.6), higher ASES score (89.5 ± 11.2) and better ROM in forward elevation (142 ± 26°) and external rotation (59 ± 11°) compared to the LP group (28.9 ± 4.8 for DASH score, P < 0.0001; 82.3 ± 9.0 for ASES score, P < 0.001; 129 ± 21° for forward elevation, P = 0.008; and 52 ± 9° for external rotation, P = 0.001). There was no significant difference in overall complication rate between the two groups, although the complication rate of screw perforation was higher in the LP-PA group (P = 0.172). ConclusionsFor PHF in elderly patients, the combination of LP fixation and PMMA prosthesis augmentation effectively improved humeral head support and reduction maintenance, providing satisfactory outcomes both radiologically and clinically. This technique also reduced the incidence of screw perforation associated with plate fixation alone, making it a reasonable option to ensure satisfactory clinical outcomes.

Outcomes following reverse total shoulder arthroplasty vs operative fixation for proximal humerus fractures: a systematic review and meta-analysis.

Proximal humerus fractures are common in the older population. A consensus on the optimal management of complex fractures requiring surgery has yet to be reached. A systematic review and meta-analysis was performed to compare clinical outcomes between reverse total shoulder arthroplasty (RTSA) and open reduction and internal fixation (ORIF). A systematic search of the literature was undertaken using the Medline®, PubMed, Embase™ and Cochrane Central Register of Controlled Trials databases. Prospective and retrospective studies comparing clinical and patient reported results as primary outcome measures were included in this review, with secondary outcome measures including complications and revision surgery. A meta-analysis was conducted. A total of 326 patients from 5 studies were eligible for inclusion in this review. Superior Constant-Murley scores (mean difference [MD]: 13.4, 95% confidence interval [CI]: 6.2-20.6; p<0.001), Oxford shoulder scores (MD: 4.3, 95% CI: 1.2-7.4; p=0.007), simple shoulder test scores (MD: 0.95, 95% CI: 0.01-1.89; p=0.05) and DASH (Disabilities of the Arm, Shoulder and Hand) scores (MD: 5.1 [1study], 95% CI: 2.1-8.1; p=0.034) were noted in patients receiving RTSA. Range of motion and revision surgery rates were also superior in this group. This study suggests that RTSA affords more favourable outcomes and lower revision rates than ORIF following proximal humerus fractures. Definitive conclusions are precluded, however, owing to small sample sizes and risk of bias in retrospective studies.

Clinical analysis of posterior axillary approach internal fixation for IdebergⅠa andⅡglenoid fractures

To investigate the efficacy of posterior axillary approach internal fixation for Ideberg Ⅰa andⅡ glenoid fractures. From December 2018 to September 2021, 9 patients with lower part of glenoid fractures were treated by posterior axillary approach, including 3 males and 6 females, aged from 50 to 78 years old. All the fractures were closed fractures. According to Ideberg type of scapular glenoid fracture was type Ⅰa in 6 cases and type Ⅱ in 3 cases. AP and lateral X-ray films of scapula were taken at 6, 12 weeks and 6 and 12 months postoperatively. Constant-Murley and disabilities of the arm shoulder and hand (DASH), and other complications were recorded at the latest follow-up. Nine patients were followed up, ranged from 6 to 15 months. And bone healing was achieved in all 9 patients at the final follow-up, the healing time 3 to 6 months, Constant-Murley score at the final follow-up ranged from 55 to 96, and DASH score ranged from 3.33 to 33.33. Both of them were better than preoperative. The posterior axillary approach internal fixation for Ideberg Ⅰa and Ideberg Ⅱ Glenoid fractures scapular fracture is satisfactory and worthy of clinical application.

A comparative study on the clinical efficacy of microplate trans-carpometacarpal joint fixation and non-trans-carpometacarpal joint fixation in treating fractures with dislocation or subluxation of the base of the fourth and fifth metacarpal bones

BackgroundThis study aimed to compare the clinical efficacy of microplate trans-carpometacarpal joint fixation and non-trans-carpometacarpal joint fixation in treating fractures and dislocation or subluxation of the base of the fourth and fifth metacarpal bones.MethodFrom 2015 to 2021, 100 cases of metacarpal basal fractures with dislocation or subluxation were randomly divided into the trans-carpometacarpal joint fixation group (group A) and non-trans-carpometacarpal joint fixation group (group B). Group A (n = 50) comprised 44 males and 6 females, with an average age of 28.8 ± 6.1 y and an Orthopedic Trauma Association (OTA) fracture classification of type B1 (n = 29) or C1 (n = 21). Group B (n = 50) comprised 45 males and 5 females, with an average age of 28.9 ± 5.7 y and an OTA fracture classification of type B1 (n = 28) or C1 (n = 22). All patients were complicated with dislocation or subluxation. The surgery time, fracture healing time, postoperative handgrip strength, and total active motion (TAM) scores of the ring and little fingers were recorded and compared between the two groups. The clinical efficacy of patients was evaluated using scoring methods such as DASH (disabilities of the arm, shoulder and hand), visual analogue scale (VAS), and Mayo at 3, 6, and 12 months after surgery.ResultsThere was no significant difference in the general indexes, surgery time, or fracture healing time between the two groups (P > 0.05). There were no significant differences in handgrip strength and TAM scores of the ring and little fingers between the two groups at 3 and 12 months postoperatively (P > 0.05), but there were significant differences in these indexes 6 months postoperatively (P < 0.05). There were no significant differences in the DASH, VAS, and Mayo scores at 3 and 12 months postoperatively (P > 0.05), but there were significant differences between the two groups in the DASH and Mayo scores (P < 0.05) but not the VAS score (P > 0.05) 6 months postoperatively.ConclusionIn the treatment of fourth and fifth metacarpal basal fractures with dislocation or subluxation, both microplate transarticular fixation and non-transarticular fixation could achieve fracture fixation and healing, and each method had advantages and disadvantages. The clinically appropriate fixation method should be selected according to the experience of the surgeon and the degree and type of fracture and dislocation.

Surgical versus non-surgical interventions for distal radius fractures: a quantitative analysis of patient-rated wrist evaluation measures

Trials to assess differences in PRWE (Patient related wrist evaluation) over time, for both surgical and non-surgical interventions post DRFs (distal radius fractures) are rare. The DASH (Disabilities of the arm, shoulder and hand) questionnaire has been shown to be improved by a greater margin in the medium term for surgical interventions, than non surgical interventions. However, a study found that PRWE can be considered superior to the DASH questionnaire for DRFs, due to greater specificity to wrist pain and function. Conflicting data makes it difficult to determine surgical vs non-surgical superiority for DRF’s over time with PRWE as a recovery metric. PubMed and Cochrane were searched for randomised controlled trials up to 31.8.23, reporting PRWE over 3, and 12 months. Data was extracted by 2 researchers. The differences in PRWE over time post surgical and non-surgical interventions was assessed using unpaired T testing. 1226 records were screened. Four studies enrolling 817 participants met the eligibility criteria and were analysed. Significantly lower PRWE in surgical intervention has been identified at the 3 month mark (p&lt;0.001). There was greater significant change in non-surgical intervention between months 3 and 12 (p&lt;0.001). Change in PRWE over time may be a good indicator of functional outcomes in DRFs post surgical or non-surgical interventions. This could inform future clinical trial design and surgical decision-making. Further work is required to design even more user-friendly and digital patient-reported outcomes specifically for DRFs.

Osteoid Osteoma of the Hand: Surgical Treatment versus CT-Guided Percutaneous Radiofrequency Thermal Ablation.

(1) Background: Osteoid osteoma (OO) is one of the most common benign bone tumors. This type of osteogenic tumor is generally characterized by a well-defined lytic area with a vascularized central nidus surrounded by sclerosis and bone thickening. The wrist and hand bones are infrequent sites for osteoid osteoma: only 10% of the cases arise in these areas. Standard treatments are surgical excision and radio-frequency ablation (RFA), both with advantages and disadvantages. This study aimed to compare the two techniques to prove if RFA could be a potential alternative to surgery in the treatment of OO of the hand. (2) Methods: Patients treated for OO of the hand between January 2011 and December 2020 were evaluated and data was collected regarding the lesions' characteristics and the treatment outcome. Each patient was followed up for 24 months and VAS pain (Visual Analogue Scale), DASH (Disability of the Arm, Shoulder and Hand), and PRWE (Patient-Related Wrist Evaluation) scores were collected. (3) Results: A total of 27 patients were included in the study: 19 surgical and 8 RFA. Both treatments showed a significant improvement in pain and functionality. Surgery was associated with a higher complication rate (stiffness and pain), while RFA was associated with a higher recurrence rate (2/8 patients). RFA allowed for a speedier return to work. (4) Conclusions: We believe that osteoid osteoma treatment with RFA in the hand should be an available alternative to surgery as it allows rapid pain relief and a swift return to work. Surgery should be reserved for cases of diagnostic uncertainty or periosteal localization.

FREE VASCULARIZED FIBULA GRAFTING AS MANAGEMENT FOR LARGE SKELETAL DEFECTS IN HUMERAL OSTEOMYELITIS IN NORTHERN IRELAND

IntroductionThe purpose of this study is to evaluate the radiological and clinical outcomes in Northern Ireland of free vascularised fibular bone grafting for the treatment of humeral bone loss secondary to osteomyelitis. Upper limb skeletal bone loss due to osteomyelitis is a devastating and challenging complication to manage for both surgeon and patient. Patients can be left with life altering disability and functional impairment. This limb threatening complication raises the question of salvage versus amputation and the associated risk and benefits of each. Free vascularised fibula grafting is a recognised treatment option for large skeletal defects in long bones but is not without significant risk. The benefit of vascularised over non-vascularised fibula grafts include preservation of blood supply lending itself to improved remodeling and osteointegration.Materials &amp; MethodsSixteen patients in Northern Ireland had free vascularised fibula grafting. Inclusion criteria included grafting to humeral defects secondary to osteomyelitis. Six patients were included in this study. Patients were contacted to complete DASH (Disabilities of the Arm, Shoulder and Hand) questionnaires as our primary outcome measure. Secondary outcome measures included radiological evaluation of osteointegration and associated operative complications. Complications were assessed via review of Electronic Care Record outpatient and in-patient documents.ResultsSix patients in Northern Ireland have been treated with free fibula grafting for humeral defects secondary to osteomyelitis. Regarding aetiology of osteomyelitis, five patients had sustained humeral fractures which were initially managed with open reduction internal fixation and complicated by infected non-union. These cases required removal of metalwork, segmental resection and placement of cement spacer with prolonged antibiotic therapy before return to theatre for vascularised fibula grafting. One patient developed native humeral osteomyelitis, the exact cause of which was unclear. Four patients were contactable for outcome score completion. The average DASH score was 45.5. (range 11.1 – 70.4). The median score was 50.2. With regard to post-operative complications, four of the six patients required return to theatre. Reasons were flap congestion, failure of metalwork at three months, donor site skin grafting for delayed healing and external fixation of graft fracture following trauma. Three patients experienced donor site morbidity in the form of delayed healing or infection requiring admission for intravenous antibiotics. One patient died due to cerebrovascular accident (CVA) within one month of return to theatre for a graft related complication - radiographic osteointegration was not assessed for this patient. At the time of this study, three of the remaining five patients have achieved graft osteointegration. Two patients are within 6 months of grafting procedure therefore too early to comment on radiographic osteoingreration. Radiographs to date are encouraging.ConclusionsFree vascularised fibula grafting for humeral shaft bone defects is a viable option for limb salvage but carries significant risk of complications. Our study highlights the need for proper informed consent regarding risk for this uncommon complex procedure which should only be undertaken by a multidisciplinary team in a specialist orthoplastic unit. This procedure is performed infrequently and our study has given us more information on risk and clinical outcomes to provide full and informed consent for patients in the future.

Muscle assessment in brachial plexus injury: A reliability study

PurposeMotor outcome following a brachial plexus injury is frequently measured to evaluate the success of surgical interventions. We aimed to identify whether the manual muscle testing using the Medical Research Council (MRC) method in adults with C5/6/7 motor weakness was reliable and whether its results correlated with functional recovery. MethodsTwo experienced clinicians examined 30 adults with C5/6/7 weakness following proximal nerve injury. The examination included using the modified MRC to assess motor outcome in the upper limb. Kappa statistics were calculated to evaluate inter-tester reliability. Correlation coefficients was calculated to explore the correlation between the MRC and the Disabilities of the Arm Shoulder and Hand (DASH) score and each EQ5D domain. ResultsWe found that grades 3–5 of the modified and unmodified MRC motor rating scales have poor inter-rater reliability when assessing C5/6/7 innervated muscles in adults with a proximal nerve injury. The Deltoid Posterior and the Extensor Carpi Radialis Longus were the only muscles (using the modified MRC) to achieve a Kappa over 0.6 indicating substantial reliability. Higher combined MRC scores correlated significantly with a lower DASH and vice versa. Similarly, higher combined scores of MRC correlated significantly with a higher rating of overall health on the EQ5D VAS. ConclusionsThis study demonstrates that the MRC motor rating scale has poor inter-rater reliability when assessing C5/C6/C7 innervated muscles in adults following proximal nerve injury. Other methods of assessing motor outcome following proximal nerve injury need to be considered.

Relationship Between Pain and Disability Among Stroke Patients.

Stroke is prevalent in Iran, and its complications can decline patients' quality of life and psychological state. This study aimed to investigate the relationship between pain following stroke (PFS) and disability in stroke patients. The current case-control study was conducted on 184 stroke patients (92 cases and 92 controls). Data collection tools included a demographic questionnaire, the Visual Analog Scale (VAS), and the Disabilities of the Arm Shoulder and Hand (DASH) questionnaire. Based on the medical files of all patients with stroke, eligible ones were invited to participate in the study via phone calls. The collected data were then analyzed. The disability rate was higher in the case group of patients with a history of hemorrhagic stroke, smoking, stroke, and diabetes (P < 0.05). The mean ± SD age was 72.45 (11.54). Also, the level of disability in patients increased with age (P = 0.000). The mean ± SD disability score was 78.63 (6.92) in patients with PFS and 54.9 (10.87) in patients without PFS. Also, R = 0.795 and R2= 0.631 indicated the significance of disability severity in patients with PFS. The prevalence of disability was higher in patients with higher PFS levels. Hence, drug interventions or rehabilitation programs can be used to reduce the disability of stroke patients.

After failed radial head arthroplasty, what are the options? Risk factors and results of revisions in a multicenter study

IntroductionFew multicenter studies have analyzed the outcome of revision surgery of radial head arthroplasties (RHA) in the medium term follow up. The objective is twofold: to determine the factors associated with revision of RHAs and to analyze the results of revision with 2 surgical techniques: isolated removal of the RHA or revision with a new RHA (R-RHA). HypothesisThere are associated factors of RHA revision and RHA revision results in satisfactory clinical and functional outcomes. MethodsTwenty-eight patients were included in this multicenter retrospective study, with all surgical indications for initial RHA being traumatic/post-traumatic. The mean age was 47 ± 13 years with a mean follow-up of 70 ± 48 months. This series included two groups: the isolated RHA removal group (n = 17) and the revision RHA with new radial head prosthesis (R-RHA) group (n = 11). Evaluation was clinical and radiological with univariate and multivariate analysis. ResultsTwo factors associated with RHA revision were identified: a pre-existing capitellar lesion (p = 0.047) and a RHA placed for a secondary indication (<0.001). Revision for all 28 patients resulted in improved pain (pre-op Visual Analog Scale 4.7 ± 3 vs. post-op 1.57 ± 2.2, p < 0.001), mobilities (pre-op flexion 118 ± 20 vs. post-op 130 ± 13, p = 0.03; pre-op extension −30 ± 21 vs post-op −20 ± 15, p = 0.025; pre-op pronation 59 ± 12 vs post-op 72 ± 17, p = 0.04; pre-op supination 48 ± 2 vs post-op 65 ± 22, p = 0.027) and functional scores. Mobility and pain control were, for stable elbows, satisfactory in the isolated removal group. When the initial or revision indication was instability, the DASH (Disabilities of the Arm, Shoulder and Hand = 10 ± 5) and MEPS (Mayo Elbow Performance score = 85 ± 16) scores were satisfactory in the R-RHA group. DiscussionIn the case of a radial head fracture, RHA is a satisfactory first-line solution without pre-existing capitellar injury, its results being much weaker in the case of ORIF failure and fracture sequelae. In case of RHA revision, isolated removal or R-RHA adapted according to the pre-operative radio-clinical exam. Level of evidenceIV.

Comparison of Clinical and Functional Outcomes after Platelet-Rich Plasma Injection and Corticosteroid Injection for the Treatment of de Quervain's Tenosynovitis.

Background Platelet-rich plasma (PRP) has local anti-inflammatory actions, which is being used as a treatment in various tendinopathies. Purpose The aim of the study is to compare the clinical results of PRP injection and corticosteroid injection in the management of de Quervain's tenosynovitis (DQTSV). Patients and Methods In this prospective study, 60 patients of DQTSV, fulfilling the predefined inclusion and exclusion criteria, were randomised into two groups. In group 1 ( n = 30), patients received a single injection of autologous PRP and in group 2 ( n = 30) they received a single injection of corticosteroid (methylprednisolone). All patients were followed up at 1 month, 3 months, 6 months, and 1 year for evaluation by Finkelstein test, visual analogue scale (VAS), DASH (Disabilities of the Arm, Shoulder and Hand) score, and Modified Mayo Wrist score (MMWS). Results In both the groups improvement occurred in Finkelstein test, VAS score, DASH score, and MMWS which were found to be statistically significant at all points of follow-ups when compared to the pre-intervention values. Comparison of scores between the two groups did not show any statistical significance. No complications were reported in PRP group. Statistically significant complications ( p -value = 0.026) like subcutaneous fat atrophy, depigmentation, and temporary increase in pain were seen in eight patients in the corticosteroid group with an overall complication rate of 26.67%. Conclusion Both the modalities are equally effective in the management of DQTSV remittance. PRP is equally effective as corticosteroid in reducing symptoms of first dorsal compartment stenosing tenosynovitis. PRP may have a lower complication profile, however, this benefit should be weighed against the slight increase in cost and time of PRP preparation and injection.

Arthroscopic repair of rotator cuff injury with bioabsorbable suture anchor vs. all-suture anchor: a non-inferiority study

BackgroundCompare all-suture anchors to traditional anchors through clinical and radiological evaluation at pre-established end-points.Materials and methodsWe performed a two-arms non-inferiority study on all-suture anchor (2.3 iconix™, Stryker) device with respect to traditional anchor (5.5 healix Advance™ BR, Depuy/Mitek) device under unpaired samples with size equal to 30 patients per group, all suffering from supraspinatus tendon rupture. We administrated DASH (Disabilities of the Arm, Shoulder and Hand); constant; and SST (Simple Shoulder Test) questionnaires in pre-operative, 3 ± 1 months post-intervention and 8 ± 1 months post-intervention. Questionnaires scores were the primary outcome. We also evaluated RMI at 3 and at 8 months after surgery to assess the presence of oedema or any loosening of the implant.ResultsAll-suture anchor approach has been proven to have non-inferior performances with respect to traditional anchor approach, according to questionnaires scores at the 3-month endpoint. We observed 26 patients with oedema by MRI (18 in control group, 6 in experimental group). In the 8-month endpoint we found persistent edema in 12 patients (all treated with healix), 2 had mobilitazions (healix), 10 had partial retears (8 healix, 2 iconix) and 1 implant failure (healix).ConclusionsAll suture devices have clinical and functional results comparable to traditional devices, while they tend to give fewer complications in terms of bone edema, loosening and retear rate. The effectiveness of all-suture devices should be further investigated in rotator cuff suture arthroscopic revision surgery, given the advantages they offer.

Dorsal Scapholunate Ligament Reconstruction by Using Palmaris Longus Tendon Graft in Chronic Static Scapholunate Dissociations: Does It Yield Favorable Radiographic and Functional Results?

Background Scapholunate (SL) instability is the most common dissociative carpal instability, and the most frequent cause of wrist osteoarthritis (OA), termed as scapholunate advanced collapse (SLAC). The aim of this study was to present the mid-term clinical and radiographic results of dorsal SL ligament reconstruction by utilizing free palmaris longus tendon graft in patients with symptomatic, chronic, static SL dissociation; while assessing the safety and efficacy of this technique, Materials and Methods In total, 42 patients with a mean age of 44.1 (range 26-53) and mean follow-up duration of 69.4 months (range 60-72) with a diagnosis of chronic, static, and reducible SL instabilities with no chondral damage were enrolled. They all underwent dorsal SL ligament reconstruction with the exam same technique. Results At the last follow-up, patients' mean preoperative SL gap improved from 4.7 (range 4-6) to 2.1 (range 2-3), as did SLA from 84 degrees (range 67-101 degrees) to 66 degrees (range 49-72 degrees)( p <0.001 for both). Preoperative mean VAS (visual analog score), DASH (Disabilities of the Arm, Shoulder and Hand), Mayo wrist scores and SF-36 scores showed significant improvements in the last follow-up visit ( p <0.001, for all). No major complications were acquired in either of the patients. Conclusion Dorsal SL ligament reconstruction by using free PL tendon graft was detected to provide successful restoration of the normal carpal alignment together with SL joint stability. This procedure, by significantly reducing pain and improving grip strength was detected to yield significantly improved clinical and functional outcomes, together with high patient satisfaction indicated by improved health-related quality of life (HRQOL) scores.

P178 Advising workers with distal arm pain to remain active: a secondary analysis of the ARM trial, a multicentre randomised controlled trial

Abstract Background/Aims Pain in the distal arm (elbow/forearm/wrist/hand) is common amongst working-aged adults and causes substantial work disability. The best strategy for managing arm pain is uncertain and patients are often referred to physiotherapy. We have recently shown in a randomised controlled trial (the ARM trial) that long-term disability was reduced among patients advised to remain active while awaiting physiotherapy, compared to advice to rest. The aim of the current study was to determine whether this approach is effective among workers, who may have to continue activities that are causing or exacerbating their pain; and whether there was any differential effect between workers doing manual versus non-manual work, and exposed versus not exposed to a range of physically demanding activities involving the upper limb. Methods The ARM trial (ISRCTN79085082) recruited patients with distal arm pain from 14 outpatient physiotherapy departments across the UK. Eligible consenting patients were randomised equally to: Advice to remain active, while awaiting physiotherapy; Advice to rest, while awaiting physiotherapy; or Immediate physiotherapy. This was done using a mixed randomisation/minimisation algorithm, maintaining treatment balance regarding treatment centre, gender, laterality, a broad categorisation of diagnosis, and baseline arm function. The primary outcome was freedom from disability at 26wks, as determined using the modified DASH (Disabilities of the Arm, Shoulder and Hand) questionnaire. In the current study, an intention-to-treat analysis was undertaken for the sub-group of trial participants in paid employment &amp;gt; =20hrs/wk at the start of the study. Results are presented as odds ratios, with 95% confidence intervals, for the probability of recovery. Results We have previously shown, among persons awaiting physiotherapy for distal arm pain, that advice to remain active is associated with improved long-term outcomes. Although not powered as a trial for workers, our findings suggest that these results also hold true for people in paid work - and there is certainly no evidence that this advice is detrimental. We have also shown that fast-track physiotherapy seems to confer no benefit, over and above therapy delivered after a period on a waiting list which calls into question the benefit of rapid access rehabilitation programmes.
