Fixation Of Humeral Fractures Research Articles

Arthroscopic fixation of humeral greater tuberosity fracture using a W-shaped suture

BackgroundPatients with greater tuberosity fractures of the humerus often require surgery. Therefore, there is a need to find a minimally invasive and effective surgical procedure with great patient outcomes.AimTo evaluate the clinical outcomes of the W-shaped suture technique under shoulder arthroscopy in the treatment of greater tuberosity fractures of the humerus.MethodsIn this retrospective study, a total of 17 patients were included. The fractures were closed, and there was no neurovascular injury. These patients underwent arthroscopically assisted reduction and internal fixation of the greater tuberosity fractures. Fixation was performed using sighting nails combined with a W-shaped suture. The imaging data of the patients were collected, and the ASES score, Constant-Murley score, and VAS score were used to evaluate the patient’s outcome. At the last follow-up (at least 1 year), the range of motion in the affected shoulder was compared with that of the contralateral side.ResultsThe operation was successful in all the patients. The average follow-up time was 13 months. There were no reported complications such as fracture displacement, nonunion, and internal fixation failure during the follow-up period. Post-operative X-ray examinations revealed good function recovery, with a healing time of between 10 and 12 weeks, and an average healing time of 11.5 weeks. Following the operation, patients reported reduced shoulder joint pain that no longer influenced their activity or caused discomfort in their daily life. The patient’s VAS score ranged from 0 to 3, with an average of 0.52 ± 0.73, while at the last follow-up, the Constant-Murley score ranged from 83 to 97, with an average of 92.33 ± 7.55. The ASES score ranged from 81 to 98, with an average of 93.15 ± 6.93. At the last follow-up, there was no significant difference in the overall range of motion with the unaffected limb.ConclusionThis study demonstrates that the W-shaped suture can be used to effectively fix the fractures of the greater tuberosity of the humerus, by increasing the fixed area to promote healing.

The Efficacy of Ultrasound for Visualizing Radial Nerve Lesions with Coexistent Plate Fixation of Humeral Shaft Fractures

IntroductionUltrasound has been commonly employed for depicting the morphology of the lesions in patients with radial nerve neuropathy, including entrapment, tumor, trauma, and iatrogenic injury. However, few studies have evaluated the efficacy of ultrasound for visualizing radial nerve lesions with coexistent plate fixation of humeral shaft fractures. This study aimed to address this special clinical issue. MethodsWe retrospectively examined the efficacy of ultrasound for visualizing radial nerve lesions with coexistent plate fixation of humeral shaft fractures based on intraoperative findings in patients who were treated in our hospital from January 2007 to June 2019. ResultsForty-six patients were included, and there was a 100% concordance between the ultrasound and intraoperative findings on radial nerve lesions. Ultrasonography revealed four types of lesions: radial nerve in continuity in thirty-one patients, neuroma in continuity in four patients, radial nerve stuck under the plate in three patients, and radial nerve transection in eight patients. The lesion radial nerve in continuity comprised two situations according to intraoperative electrodiagnostic test results, which could not be differentiated by ultrasonography, radial nerve in continuity treated with neurolysis in twenty-five patients and radial nerve in continuity treated with nerve graft in six patients. ConclusionUltrasonography can accurately depict radial nerve lesions with coexistent plate fixation of humeral shaft fractures. It provides a basis for determining the extent of nerve damage in all patients except those with the lesion radial nerve in continuity, which is conducive to making treatment decisions as early as possible.

A Tensionable Suture-based Cerclage Is an Alternative to Stainless Steel Cerclage Fixation for Stabilization of a Humeral Osteotomy During Shoulder Arthroplasty.

Fixation of periprosthetic humeral fractures is most commonly obtained with steel-based wires or cables; however, disadvantages with these constructs are numerous. Suture-based cerclages offer the advantage of easy handling, less radiographic interference, and risk of metallosis, as well as decreased risk of cutting into the soft humeral bone. Therefore, the purpose of this study was to compare a suture-based cerclage to a stainless steel wire cerclage (SSWC) for stabilization of the humerus during shoulder arthroplasty. In part I of the study, SSWC fixation was compared with single-looped tape cerclage and a double-looped tape cerclage (DLTC) fixation. In part II, a subsidence test was performed on 12 cadaveric humeri. After an osteotomy, the humeri were secured with either a SSWC or DLTC. Subsequently, a metal wedge was introduced into the humerus to simulate the stem of a shoulder arthroplasty. In part I, load to 2-mm displacement was significantly higher for the DLTC construct compared with the SSWC construct (2,401 ± 483 N versus 750 ± 33 N; P < 0.0001). Load to failure was 935 ± 143 N with the SSWC, 1,737 ± 113 N with the single-looped tape cerclage, and 4,360 ± 463 N with the DLTC constructs, and all differences were statistically significant (P < 0.05). In part II, load at 20-mm subsidence was higher for the DLTC (320 ± 274 N) compared with the SSWC (247 ± 137 N), but no significant difference was observed (P > 0.05). However, gap displacement at 20 mm subsidence was significantly lower with the DLTC construct (0.33 ± 0.31 mm versus 0.77 ± 0.23 mm; P = 0.009). Load to failure was higher with the DLTC construct compared with the SSWC construct (4,447 ± 2,325 N versus 1,880 ± 1,089 N; P = 0.032), but the final gap displacement did not differ significantly (DLTC 5.23 ± 6.63 mm versus SSWC 6.03 ± 8.82 mm; P > 0.05). A DLTC has higher load to failure and trends toward lower gap displacement compared with a SSWC. The DLTC construct may therefore be a viable alternative for fixation of periprosthetic fractures or osteotomies of the humeral shaft during shoulder arthroplasty.

ORIF versus MIPO for humeral shaft fractures: a meta-analysis and systematic review of randomized clinical trials and observational studies.

There is no consensus on the optimal operative technique for humeral shaft fractures. This meta-analysis aims to compare minimal-invasive plate osteosynthesis (MIPO) with open reduction internal fixation (ORIF) for humeral shaft fractures regarding non-union, re-intervention, radial nerve palsy, time to union, operation duration and functional outcomes. PubMed/Medline/Embase/CENTRAL/CINAHL were searched for both randomized clinical trials (RCT) and observational studies comparing MIPO with ORIF for humeral shaft fractures. Effect estimates were pooled across studies using random effects models and presented as weighted odds ratio (OR), risk difference (RD), mean difference (MD) and standardized mean difference (SMD) with corresponding 95% confidence interval (95%CI). Subgroup analysis was performed stratified by study design (RCTs and observational studies). A total of two RCT's (98 patients) and seven observational studies (263 patients) were included. The effect estimates obtained from observational studies and RCT's were similar in direction and magnitude. MIPO carries a lower risk for non-union (RD: 5%; OR 0.3, 95% CI 0.1-0.9) and secondary radial nerve palsy (RD 5%; OR 0.3, 95%CI 0.1- 0.9). Nerve function eventually restored spontaneously in all patients in both groups. Results were inconclusive regarding re-intervention (RD 7%; OR: 0.7, 95%CI 0.2-1.9), infection (RD 4%; OR 0.4, 95%CI 0.1-1.5), time to union (MD -1 week, 95%CI -3 - 1) and operation duration (MD -13 minutes, 95%CI -38.9 - 11.9). Functional shoulder scores (SMD 0.01, 95%CI -0.3 - 0.3) and elbow scores (SMD 0.01, 95%CI -0.3 - 0.3) were similar for the different operative techniques. MIPO has a lower risk for non-union than ORIF for the treatment of humeral shaft fractures. Radial nerve palsy secondary to operation is a temporary issue resolving in all patients in both treatment groups. Although both treatment options are viable, the general balance leans towards MIPO having more favorable outcomes.

A Shift From Non-operative Care to Surgical Fixation of Pediatric Humeral Shaft Fractures Even Though Their Severity Has Not Changed.

Introduction: Humeral shaft fractures have traditionally been treated non-operatively due to their good union and low rate of functional impairment. In the recent years, upper extremity fractures and their operative treatment have increased in children. Nevertheless, the trends of humeral shaft fractures are not clear.Materials and Methods: All children aged <16 years, with a humeral shaft fracture in the geographical catchment area of Northern Finland Hospital District, with a yearly child population-at-risk of ~86 000 from the year 2001 until the end of 2015 were included. There were 88 cases, who comprised the study population. Radiographs were available of all. Injury, patient, and treatment characteristics were reviewed from hospital databases.Results: There was an increasing trend of surgical fixation of humeral shaft fractures during the 15 years' study period (β = 1.266, 95% CI 0.17 to 2.36, p = 0.035). However, we found no patient or fracture-related reasons that could have explained the increasing trend of surgical care. Comminuted fracture increased the risk of operative treatment 8-fold (Odds Ratio, OR 7.82, 95% CI 1.69 to 36.3, p = 0.009). Higher age, greater angular deformity or greater diameter of the humerus were not associated with the increased operation risk.Conclusions: The treatment philosophy concerning pediatric humeral shaft fractures has presented a shift from conservative care to surgical fixation. To authors' understanding there is not evidence supporting the increasing rate of osteosynthesis.

Anteromedial Surface Plating for Midshaft Fracture Humerus Through an Anterolateral Approach - A Better Option than Anterolateral Plating.

Introduction:Osteosynthesis by plate fixation of humeral shaft fractures as a gold standard for fracture fixation has been proven beyond doubt. However, during conventional anterolateral plating Radial nerve injury may occur which can be avoided by applying plate on the medial flat surface. The aim of this study was to evaluate the results of application of plate on the flat medial surface of humerus rather than the conventional anterolateral surface.Materials and Methods:This study was conducted between Oct 2010 to Dec 2015. One-hundred-fifty fracture shafts of the humerus were treated with the anteromedial plating through the anterolateral approach.Results:One-hundred-fifty patients with a fracture shaft of the humerus were treated with anteromedial plating. Twenty were female (mean ±SD,28 years±4.5) and 130 were male (mean ± SD, 38 years±5.6). One hundred and forty-eight out of 150 (98.6%) patients achieved union at 12 months. Two of three patients developed a superficial infection, both of which were treated successfully by antibiotics and one developed a deep infection, which was treated by wound debridement, prolonged antibiotics with the removal of the plate and subsequently by delayed plating and bone grafting.Conclusion:In the present study, we applied plate on the anteromedial flat surface of humerus using the anterolateral approach. It is an easier and quicker fixation as compared to anterolateral plating because later involved much more dissection than a medial application of the plate and this application of plate on a medial flat surface, does not required Radial nerve exposure and palsy post-operatively. The significant improvement in elbow flexion without brachialis dissection is also a potential benefit of this approach. Based on our results, we recommend the application of an anteromedial plate for treatment of midshaft fractures humerus.

Treatment of distal humeral fractures in elderly patients: where are we in 2020? A review article

Distal humeral fractures are increasing in the elderly population and pose a difficult clinical problem as orthopaedic surgeons attempt to maximize return of function and avoid complications. Many treatments have been suggested for distal humeral fractures in the elderly, with operative intervention becoming a mainstay of treatment for active patients. Open reduction internal fixation (ORIF) and total elbow arthroplasty (TEA) have been utilized with both success and complications. The available literature appears to be equivocal on the ideal treatment of geriatric distal humeral fractures, with well-done TEA and ORIF demonstrating similar outcomes. Failed fixation of geriatric distal humeral fractures can be reliably converted to TEA without worsened outcomes but requires a second surgery. TEA demonstrates equivalent outcomes, but with activity limitations for the lifespan of the patient that may inhibit the use of walking aids. There also may be decreased hardware survivorship when TEA is employed for acute fracture. Surgeons and patients must weigh the risks and benefits of treatment with TEA associated with functional restrictions and possible decreased hardware survivorship. TEA does not have the reliable fallback option, but ORIF requiring a second surgery can be converted to TEA.

Solely sutures is a reliable fixation for valgus-impacted proximal humeral fractures

PurposeValgus impacted proximal humeral fractures with substantial displacement may severely compromise shoulder function and open reduction can therefore be considered. Internal fixation hardware may eventually however constitute problems. In a small subset of these fractures, in which there is no medial comminution and intact blood supply it is possible to use a least possible fixation method with solely sutures through the tendons of the rotator cuff and the shaft as described by Bigliani 1990. The aim of the present study was to investigate the outcome of this fixation method in a retrospective series of patients. MethodsTwenty-seven patients, 23 women and 4 men, with a mean age of 66 years (53–83) and minimum follow-up time of 2 years (2–11 years) accepted follow-up with standard shoulder radiographs and 22 were examined with Oxford Shoulder Score (OSS), Constant-Murley (CM) shoulder score and Numeric Rating Scale for pain (NRS). Reoperations or adverse events were recorded. ResultsThe median OSS was 45 (range 5–48) and CM 63 (range 21–98). The relative CM score was 81% of the uninjured side and median NRS 0 (range 0–5). No reoperations were undertaken. One patient had a complete avascular necrosis (AVN), 3 patients had a partial AVN of the humeral head and two a partial resorption of the greater tuberosity. ConclusionThe use of sutures only for fixation of displaced valgus-impacted proximal humeral fractures provided a relatively reliable outcome with good functional scores and no reoperations. There appears to be no need for the use of hardware for fixation of this rare subset of fractures.

Comparison of outcome with medial versus lateral approach for operative fixation of superacondylar humeral fractures in paediatric patients.

Objectives: To compare the outcome in terms of carrying angle with medial versus lateral approach in the treatment of these fractures among children. Study Design: Randomized Clinical trial. Setting: Department of Orthopaedic Surgery Civil Hospital Bahawalpur and Nishtar Hospital Multan. Period: From June 2018 to September 2019. Material &amp; Methods: A total of 154 children of both genders, aged 2-14 years having supracondylar humeral fracture of type II and III, with duration of fracture within 7 days, were enrolled. Patients were divided in two groups (77 in each group), group A and group B. Group A was managed by open reduction internal fixation (ORIF) with cross K-wire through medial approach and group B underwent lateral approach. Results: Out of 154 cases, 102 (66.2%) were boys and 52 (33.8%) were girls. Overall, mean age was noted to be 7.98 ± 2.23 years. Obesity was present in 16 (10.4%) cases. Mean duration of fracture was noted to be 4.21 ± 1.34 days while 106 (68.8%) had duration less than 5 days. There were 119 (77.3%) cases with history of fall and 35 (22.7%) had history of road traffic accidents (RTA). Sixty one (39.6 %) cases were classified as Gartland type II fractures while remaining 93 (60.4 %) were type III fractures. Excellent outcome with carrying angle 0–5o in group A was noted to be 67 (87 %) while that of group B was 54 (70.1%) (p = 0.011). Conclusion: Medial approach for the treatment of pediatric SHF was noted to be superior in terms of postoperative carrying angle having satisfactory outcome in comparison with the lateral approach.

Bone resorption of the greater tuberosity after open reduction and internal fixation of complex proximal humeral fractures: fragment characteristics and intraoperative risk factors

In complex proximal humeral fractures, bone resorption of the greater tuberosity is sometimes observed after open reduction and internal fixation (ORIF). However, this has not been well characterized, and risk factors for resorption are not completely understood. We aimed (1) to identify the risk factors associated with bone resorption of the greater tuberosity and (2) to quantify the geometric and bone density characteristics associated with bone resorption using 3-dimensional computed tomography models in complex proximal humeral fractures treated with ORIF. We identified a retrospective cohort of 136 patients who underwent ORIF of 3- or 4-part proximal humeral fractures; greater tuberosity resorption developed after ORIF in 30 of these patients. We collected demographic, fracture-related, and surgery-related characteristics and performed multivariable logistic regression analysis to identify factors independently associated with the development of greater tuberosity resorption. Furthermore, we identified 30 age- and sex-matched patients by use of propensity score matching to perform quantitative fragment-specific analysis using 3-dimensional computed tomography models. After the fragment of the greater tuberosity was identified, the number of fragments, the relative fragment volume to the humeral head, and the relative bone density to the coracoid process were calculated. Measurements were compared between matched case-control groups. We found that an unreduced greater tuberosity (odds ratio [OR], 10.9; P < .001), inadequate medial support at the calcar (OR, 15.0; P < .001), and the use of an intramedullary fibular strut (OR, 4.5; P = .018) were independently associated with a higher risk of bone resorption. Quantitative fragment-specific analysis showed that greater tuberosities with a larger number of fragments (5 ± 2 vs. 3 ± 2, P = .021), smaller fragments (9.9% ± 3.8% vs. 18.6% ± 4.7%, P < .001), and fragments with a lower bone density (66.4% ± 14.3% vs. 88.0% ± 18.4%, P = .001) had higher rates of resorption. An unreduced greater tuberosity or inadequate medial support increases the risk of greater tuberosity resorption, as do a larger number of fracture fragments, smaller fragments, and lower bone density. Additionally, fibular strut grafting is an independent risk factor for tuberosity resorption. Further study is needed, but alternatives to strut grafting such as femoral head allograft may warrant serious consideration.

Effect of surgical approaches on deltoid innervation and clinical outcomes in the treatment of proximal humeral fractures.

Objectives This study aims to investigate the effects of deltopectoral and anterolateral acromial approaches commonly used in open reduction-internal fixation of proximal humeral fractures on the clinical outcomes, and axillary nerve damage through electrophysiological assessment.Patients and methods Forty-eight patients (22 males, 26 females; mean age 47.9±13.2 years; range, 22 to 73 years) diagnosed with Arbeitsgemeinschaft für Osteosynthesefragen (AO)/Orthopaedic Trauma Association (OTA) type 11 proximal humeral fractures who underwent osteosynthesis with anatomical locking plates in our hospital between January 2015 and June 2016 were prospectively examined. The patients were divided into two groups according to either the deltopectoral or anterolateral deltoid-split surgical approach used. Clinical outcomes were evaluated using the Disabilities of the Arm, Shoulder, and Hand (DASH) scores and Constant-Murley scores (CMS) obtained at three- and 12-month follow-up visits. Needle electromyography (EMG) was performed for the electrophysiological assessment of the deltoid muscle.Results There were no significant differences between the groups in terms of demographic data, follow-up times, and complications. DASH scores and CMS obtained postoperatively at three months (p=0.327 and p=0.531, respectively) and 12 months (p=0.324 and p=0.648, respectively) revealed no significant differences. In addition, the two groups did not significantly differ with respect to the presence of EMG abnormalities (p=0.792). Avascular necrosis of the humeral head was detected in only two patients from the deltopectoral group.ConclusionDeltopectoral and anterolateral approaches do not differ regarding the presence of postoperative EMG abnormalities and functional outcomes. Surgeons can thus adopt either approach. However, dissection without damaging the soft tissue should be performed in both approaches.

Varus malposition relates to functional outcomes following open reduction and internal fixation for proximal humeral fractures: A retrospective comparative cohort study with minimum 2 years follow-up

Background: The aim of this study was to evaluate functional outcomes in patients with varus malposition following open reduction and internal fixation of displaced proximal humeral fractures.Methods: Data of 685 patients with a mean age of 67±15.8 years (67% female), that were treated by open reduction and internal fixation for a displaced proximal humeral fracture at a level 1 trauma center, were analyzed. On standardized x-ray imaging, the degree of varus displacement was measured over a minimum of two years follow-up and patients were divided into three groups. Group A: anatomic or <10° of varus or valgus malposition, group B: 10–20° of varus malposition and group C: >20° varus malposition, while anatomic head-shaft-angle was defined 135° The groups were compared with regards to functional outcomes by means of the Constant Score (CS).Results: In 565 patients with anatomic to minor <10° varus or valgus malposition (Group A), the mean CS was 72.5 ± 18.8 points. The %CS to the uninjured side was 87.2 ± 24.1 and the age and gender normalized nCS was 84.7 ± 21.7. In comparison, in group B (10–20° varus) the mean CS was 64.7 ± 16.9, the mean %CS was 84.5 ± 18.3 and the mean nCS was 76.2 ± 20.6. In group C (>20° varus) the mean CS was 54.1 ± 19.5, the mean was %CS: 72.3 ± 26.4 and the mean nCS was 64.8 ± 23.8 (p = 0.02, p = 0.03, p = 0.01). Overall, the CS, %CS and nCS correlated significantly with the degree of varus position (Pearson correlation, r = 0.23, r = 0.21, r = 0.25).Conclusion: Varus malposition is related to inferior functional outcomes compared to anatomic healing in patients treated by open reduction and internal fixation for proximal humeral fractures. The data supports suggestions to prevent varus malposition in open reduction and internal fixation. In severe >20° of varus malposition, revision surgery should be considered.

Comparison between MIPO and the deltopectoral approach with allogenous fibular bone graft in proximal humeral fractures.

BackgroundThe purpose of this study was to investigate the clinical differences between open reduction and plate fixation via a deltopectoral approach with allogenous fibular bone graft and a minimally invasive plate osteosynthesis (MIPO), in Neer's classification two-, three- part proximal humeral fractures.MethodsIn this retrospective study, 77 patients with two-, three-part proximal humeral fractures were treated at two different institutions. Clinical and radiological evaluations were performed in 39 patients, who underwent MIPO at one institution (group A), and 38 patients, who underwent a deltopectoral approach with allo-fibular bone graft (group B) at another institution. The results between the groups were compared.ResultsThe MIPO technique was significantly less time consuming and caused less bleeding than the deltopectoral approach with allo-fibular bone graft (P<0.05). The duration of the fracture union was significantly reduced in group A (14.5±3.4; range, 10–22 weeks) compared to group B (16.4±4.3; range, 12–28) weeks (P<0.05). There were no statistically significant differences between the two groups when evaluating the visual analog scale and Constant scores between the two groups, 1 year postoperatively. In radiological evaluation, there was no difference in radiological outcomes between the two groups. There were no statistically significant differences in malunion between the two groups. ConclusionsThe MIPO technique and deltopectoral approach with allo-fibular bone graft for two-, three-part proximal humeral fractures, show similar clinical and radiological results. However, allogenous fibular grafts require longer surgery, cause more bleeding, and result in longer fracture healing time than MIPO technique.

Evaluation of racial disparities in postoperative opioid prescription filling after common pediatric surgical procedures

BackgroundRacially disparate pain management affects both adult and pediatric patients, but is not well studied among pediatric surgical patients after discharge. The objectives were to evaluate racial disparities in pediatric postoperative opioid prescription filling. MethodsThis retrospective cohort study included black or white pediatric Medicaid patients who underwent tonsillectomy, supracondylar humeral fracture fixation, or appendectomy (2/2012–7/2016). Patients were followed for 14 days post-surgery to identify opioid prescription fills. Logistic regression models evaluated the association between race and the probability of filling an opioid prescription. ResultsAmong 39,316 surgical patients, the proportions of patients with post-surgical opioid prescriptions were 66.0%, 83.9%, and 68.5%, among tonsillectomy, supracondylar fracture, and appendectomy patients, respectively. The proportion of black appendectomy patients with a postoperative opioid prescription was significantly lower compared to white patients (65.0% vs. 69.2% respectively, p = 0.03), but was no longer significant after adjusting for other patient and provider characteristics. There were no differences by race in opioid prescription filling among other surgical patient groups. ConclusionsThe present study did not identify racial disparities in opioid prescription filling in adjusted analyses. Racial differences in unadjusted postoperative opioid prescription filling among appendectomy patients may be explained in part by longer postoperative length-of-stay among black children.

Lateral Condyle Fracture of the Humerus in Children: Kirschner Wire or Screw Fixation?

The treatment of the displaced fracture of the lateral condyle of the distal humerus in children aims not only to avoid nonunion, malalignment, and impairment of the range of motion of the elbow but also to prevent delayed healing and the development of any prearthrotic deformity. To date there is no agreement on what kind of osteosynthesis should be used. So far, the screw fixation and Kirschner wire fixation have both been applied. Therefore, the goal of this study was to compare the outcome of these two methods. A retrospective cohort study was undertaken including 43 patients aged 2 to 13 years who underwent osteosynthesis for a condylar fracture of the humerus over a period of 10 years. The electronic archive, including the radiological diagnostics, was analyzed. Statistical analysis was performed using IBM SPSS Statistics 20.0. Statistical significance was set at an α level of p = 0.05. Kirschner wire fixation was performed in 48.9% of condylar fractures of the humerus while screw fixation (alone or in combination with a pin) was assessed with a percentage of 51.1% of the cases in this study. Screw fixation only was applied in 20.9% of fractures of the lateral condyle. The selection of the method was independent of the age of the patient (p = 0.2). The comparison of the rate of complications and an impaired range of motion after Kirschner wire osteosynthesis to the rate after screw osteosynthesis showed a significantly lower percentage for the Kirschner wire group (p = 0.046). No case of nonunion, nerve palsy, or pin migration was detected in any patient in this study. Kirschner wire fixation of condylar humeral fractures in children resulted in a lower rate of complications than screw fixation. No case of nonunion of the fracture was found in the patients that we investigated so that we conclude that Kirschner wires sufficiently adapt the fracture in these cases. Level III.

Locking compression plate fixation versus intramedullary nailing of humeral shaft fractures: which one is better? A single-centre prospective randomized study.

To compare the radiological and clinical outcomes of interlocking nail (ILN) and locking plate fixation (LCP) for humeral shaft fractures. A total of 63 patients with displaced humeral shaft fractures between October 2014 and January 2017 were evaluated prospectively. They were divided randomly into two as LCP fixation (group 1) and interlocking nail (ILN) (group 2). Functional outcomes were evaluated using the Disabilities of the Arm, Shoulder, and Hand (DASH), American Shoulder and Elbow Surgeons (ASES), the University of California at Los Angeles (UCLA) shoulder scores, and Short Form-36 (SF-36) questionnaires, and pain was assessed with visual analogue scale (VAS). After fracture callus was radiologically observed, DASH, ASES, and UCLA scores as well as SF-36 questionnaires and VAS results were noted to have no significant difference between the two groups (p = 0.109, p = 0.082, p = 0.146, p = 0.322, and p = 0.175, respectively). At the last follow-up (post-operative 24months), the UCLA score was significantly better in group 1 (p = 0.034), whereas VAS result was significantly worse in group 2 (p = 0.017). DASH, ASES scores, and SF-36 questionnaires had no difference (p = 0.193, p = 0.088, p = 0.289). Other parameters revealed no significant differences. Fracture consolidation was observed at a mean of fourmonths in both groups (3 to 7months in group 1 and 3 to 8months in group 2) (p = 0.189). Four patients in group 1 and five patients in group 2 underwent surgery for nonunion (p = 0.725). Post-operative radial nerve palsy was seen in one patient in group 2. Two patients in group 1 with superficial infection were treated with antibiotics, and they recovered. Regarding our results, the LCP group had significantly better shoulder function than the ILN group, whereas the ILN group had significantly less pain, with similar complication rates. Therefore, both procedures are favourable surgical options for patients with humeral shaft fractures.

Intramedullary Nail Fixation for the Treatment of Pathologic Humeral Shaft Fractures.

The goal of this study was to report the clinical outcomes of pathologic humeral shaft fractures treated with reamed or unreamed intramedullary nail fixation in an era of longer patient survival. A retrospective review was conducted of all patients who underwent intramedullary nail fixation performed by a single surgeon for pathologic humeral shaft fractures at a Level I trauma center from 2009 to 2017. Of the 25 patients who were identified, 9 were excluded. Groups were categorized according to whether they underwent reamed or unreamed fixation, and they were evaluated for evidence of union, complications, and reoperation. Of the patients, 11 underwent an unreamed procedure and 5 underwent a reamed procedure. Mean length of follow-up was 51.5 weeks. Of the patients who participated, 12 (75%) showed evidence of union and 2 patients (12.5%) showed evidence of nonunion, with no statistical difference between the groups. Five patients (31.3%) had complications. One nonunion occurred in the reamed group and did not require reoperation. In the unreamed group, complications consisted of 1 delayed union, 1 nonunion treated with revision intramedullary nail fixation, and 2 cases of disease progression that required reoperation. Intramedullary nail fixation of pathologic humeral shaft fractures achieves rates of union parallel to those seen with fixation in a healthy population. The length of follow-up in the current study was longer than the life expectancy reported by previous authors, which can be attributed to improvements in the treatment of cancer. The current authors argue that unreamed fixation is the optimal technique because it yields similar outcomes to a reamed approach and is faster and potentially safer.

Iatrogenic radial nerve palsy in open reduction internal fixation of humeral diaphyseal fracture by anterolateral approach

This study was done to determine frequency of post-operative iatrogenic radial nerve palsy in open reduction and internal fixation of humerus fracture by anterolateral approach. It is a Cross sectional study was done on 20 humerus shaft fractures were treated at adichunchanagiri hospital and research centre, nagamangala, Karnataka over a period of 12 months from septemeber 2019 to august 2020. Among these patients post operatively iatrogenic radial nerve palsy were noted. Among 20 patients, 16 were male and 4 were female. Median age was 32.5 years. Out of these 17 patients were has been treated with dynamic compression plate and 2 with locking compression plate. All the fractures were diaphyseal, at distal / middle third level. Among 20 patients 2 patients developed iatrogenic radial nerve palsy. In these patients there was no macroscopic lesion and nerve was in continuity and beginning of clinical recovery was seen in within 3 months. The incidence of secondary nerve palsy after surgey is 10%. Secondary nerve palsy is always transient recovers with time with dynamic splint in extent position of wrist and fingers. Open reduction and internal fixation provide greater patient comfort and better alternative to conservative treatment.

Outcome of proximal humeral fracture fixation with K wires Vs Philos plating

Introduction- Proximal humerus fractures represent one of the most common fracture type in upper extremity. Aim- this study aimed to see outcome of proximal humeral fracture fixation with K wires vs PHILOS plating Material and Method- A prospective study was conducted overthree years of a total of 50 patients with proximal humerus fracture. Patients were divided into two groups by randomized controlled trial .Group 1 included 25 patients who were treated with closed reduction and percutaneous k wire fixation. Group 2 included 25 patients who were treated with ORIF with PHILOS plate .All these 50 patients were followed up for mean duration of 12 months Results- Mean neer score at final follow up was 80 in group 1 patients while it was 90 in group 2 patients As per the Neers scoring system ; 7 patients (28%) in group 1 had excellent results ,12 patients(48%)had satisfactory Results,2 patients( 8%) had unsatisfactory results while 4 patients (16%) had poor outcome For Group 2 ,as per Neers scoring system 12 patients (48%) had excellent results,9 patients (36%) had satisfactory results, 2 patients (8%) had unsatisfactory results while 2 patients (8%) had poor outcome. Conclusion-In conclusion it was found that K-wires fixation for proximal humerus fractures type III and type IV (Neer’s) gives inferior results than proximal humerus interlocking system (PHILOS) Keywords: K-wire, proximalhumerus interlocking system Neer’s Score,

Patient outcomes after humeral fracture surgery during the COVID-19 outbreak in Spain

BackgroundThe global spread of the 2019 novel coronavirus (COVID-19) has profoundly affected the way we conduct our health care practices. The goal of this paper is to report the outcomes of 11 patients who underwent humeral fracture surgery in the first few weeks of the COVID-19 outbreak in Spain.MethodsThis was a retrospective case series of 11 patients who underwent humeral fracture surgery during the first weeks of the COVID-19 outbreak in Spain, between March 10 and April 25, 2020. The clinical outcomes of these operative patients were monitored up to May 12, 2020, the final date of follow-up, a minimum of 15 days after all patients were discharged from the hospital. COVID-19 infection, mortality, demographic, clinical, and laboratory data were analyzed.ResultsThirty-six humeral fractures were recorded between March 10 and April 25, 2020. During this period, humeral fracture fixation was the third most common surgery for fracture in our institution after hip fracture and ankle fracture surgery. Eleven patients underwent surgery (30.5%), of whom 7 were women (63.3%). The mean age was 64.8 years (standard deviation, 13.5). Nine operated cases had a proximal humerus fracture and 2 had a humeral shaft fracture. One of the 11 patients was positive for SARS-CoV-2 on the basis of the quantitative reverse transcription polymerase chain reaction of throat swab samples. The overall median surgical time was 101.2 minutes (standard deviation, 28.4). The overall median hospital length stay for the patient discharged was 2.2 days (range, 1-4 days). No COVID-19 nosocomial intrahospital infection occurred, and no patient reported COVID-19 infection during the 15 days after hospital discharge. No intrahospital mortality was recorded. Furthermore, no COVID-19 infection was reported in the shoulder surgeons who performed the surgeries.ConclusionsAlthough humeral fractures were not the most frequent fractures during this outbreak, some required surgery. With good preoperative management that included reverse transcription polymerase chain reaction for COVID-19 and chest radiographs, protective measurements for the surgical team, and rapid discharge of the patients, we were able to operate on 11 humeral fractures with no COVID-19 nosocomial intrahospital infection in the patients or in the shoulder surgeons who performed the surgeries.
