Clinical effect of modified Henry approach in treating AO type B and C distal radius fractures

To investigate the clinical effect in treating AO type B and C distal radius fractures with modified Henry approach. Retrospectively analysis of 20 patients with AO type B and C distal radius fractures between June 2021 and May 2022, they were treated by modified Henry approach. There were 6 males and 14 females, aged from 35 to 78 years old, 8 patients on the left and 12 on the right. The patients' general data, fracture healing time, postoperative complications, last-time follow up radiographic parameters(volar inclination angle, ulnar deviation angle and radius height), wrist range of motion, range of forearm rotation and functional outcoming of the wrist joint according to Mayo scoring were observed of each patient. All patients were followed-up, the time was (13.3±2.3) months, ranged from 12 to 18 months. All the fractures were healed, the fracture healing time was (12.6±2.5) weeks, ranged from 10 to 16 weeks. There were no complications such as poor wound healing, incision infection, iatrogenic median nerve injury, delayed union, nonunion and malunion during the postoperative follow up. According to the X-ray measurement in the last-time follow up, the volar inclination angle was (11.4±4.0) °, the ulnar deviation angle was (20.9±2.2) ° and the radius height was (10.3±1.2) mm. The wrist range of motion was (65.3±5.8) ° for volar flexion, (60.2±4.2) ° for dorsal extension, (37.8±4.1) ° for ulnar deviation, (27.0±3.7) ° for radial deviation. The range of forearm rotation was(80.4±4.1) ° for pronation, (78.6±3.7) ° for supination. According to Mayo scoring, the wrist function was evaluated as excellent in 12 cases, good in 6 cases and fair in 2 cases, the excellent and good rate was 90%. Modified Henry approach can better expose the ulnar and volar fragments in distal radius, especially useful for reducting the distal radius with complex bi-columnar fractures.

Application of distal radius coronal bone structure matching in the treatment of distal radius fractures

To investigate the clinical effect of coronal bone structure matching(CBSM)in the treatment of distal radius fracture. A total of 39 cases of distal radius fracture between Jannary 2018 and Jannary 2022 were included in this study. Among them there were 22 males and 17 females with an average age of (48.9±16.3) years old, ranged from 22 to 65 years old. All patients were treated with open reduction and internal fixation with plates. Based on the measurement of CBSM value on the X-ray film the next day after surgery. All patients were divided into matched group and mismatched group according to the coronal bone structure matching in the normal range or not. There were 27 patients in the matched group, including 15 males and 12 females, the age ranged from 22 to 64 years old with an average of (48.0±16.2) years old. AO classification of fracture was C1 in 6 cases and C2 in 21 cases;the operation time ranged from 1 to 6 days after injury;9 cases were complicated with ulnar styloid process fracture. There were 12 patients in the mismatched group, including 7 males and 5 females;the age ranged from 22 to 65 years old with an average of (48.8±15.8) years old. AO classification of fracture was C1 in 4 cases and C2 in 8 cases;the time from injury to operation ranged from 1 to 5 days;4 cases were complicated with ulnar styloid process fracture. The X-ray films were used to evaluate fracture healing, humeral height, ulnar angle and palm tilt angle at 3 months after operation. The range of wrist motion(pronation, supination, palmar inclination and dorsiflexion), function outcomes(Gartland-Werley score) and pain levels (visual analogue scale, VAS) were compared between the two groups at the last follow-up. The average follow-up time of 39 patients were(9.5±4.3)months, ranged from 6 to 14 months. All patients healed in one stage without postoperative infection, fracture nonunion and fracture displacement occurred. Compared with match group at the last follow-up, the VAS in the mismatch group was increased[(2.5±1.3)points vs (1.6±1.0)points], the wrist pronation were decreased[(70.5±12.6)° vs (80.5±9.4)°], with statistically significant difference(P<0.05). There was no significant difference in the range of motion(supination, palmar inclination, dorsiflexion)and excellent good rate between the two groups at last follow-up after operation (P>0.05). Wrist dysfunction, limited pronation, and wrist pain may occur when the postoperative matching degree of the distal radius fracture is not within the normal range.

A Comparison Between Volar Locking Plates and Percutaneous Pinning in the Treatment of Distal Radius Fractures: A Systematic Review

Percutaneous fixation with Kirschner wires and open reduction and internal fixation with volar locking plates are the most common surgical techniques for managing distal radius fractures (DRFs). As the superiority of either technique is yet to be established, we aimed to conduct an updated systematic review to compare these techniques for the optimal management of unstable DRFs. We conducted a comprehensive literature search to identify studies comparing fixation outcomes for DRFs between groups treated with Kirschner wires and those treated with volar locking plates. Only randomized controlled trials (RCTs) were included. The revised Cochrane risk-of-bias tool was used to assess the methodological quality of RCTs. Meta-analyses were performed only on outcome measures that were reported at the same time points using the same metrics across three or more RCTs. Evaluated outcomes included the Disabilities of the Arm, Shoulder, and Hand (DASH) score, grip strength, wrist range of motion, and radiological outcomes. We also assessed the Patient-Rated Wrist Evaluation (PRWE) score and incidence of complications. Fourteen RCTs with 2,226 patients were included in the meta-analysis. DASH scores were significantly lower in the plating group at all time points. PRWE outcomes favored the plating group at follow-ups greater than 1 year. There were no significant differences in radiological outcomes or incidence of complications between the two groups. Although the plating group provided marginally better functional outcomes at 1 year after surgery, the K-wire group remained a viable alternative. The reported differences should be interpreted cautiously because of the inherent variability of the included RCTs. High-quality RCTs with strict inclusion criteria and standard postoperative protocols are essential to generalize our results across all age groups and fracture types to overcome our study's limitations.

Efficacy and safety of volar locking plate versus cast immobilization for distal radius fractures: a systematic review and meta-analysis of randomized controlled trials

Volar locking plates (VLPs) are increasingly used for distal radius fractures (DRFs), yet their efficacy compared to cast immobilization remains debated. This meta-analysis aimed to compare VLPs versus cast immobilization for DRFs across various follow-up durations. Randomized controlled trials reporting patient-reported functional scores, wrist range of motion (ROM), radiological assessments, and complications were included. Meta-analysis was performed for 6-week, 3-month, 6-month, 12-month, and &gt;12-month follow-ups. Subgroup analysis stratified studies by age group, ≥ 60 years and &lt; 60 years. VLPs showed significantly lower Disabilities of the Arm, Shoulder, and Hand (DASH) scores at 6 weeks (p &lt; 0.001), 3 months (p &lt; 0.001), 12 months (p = 0.012), and &gt; 12 months (p &lt; 0.001), and lower PRWE scores at 6 weeks (p &lt; 0.001), 3 months (p = 0.048), and &gt;12 months (p = 0.032). Wrist ROM favored VLPs at 6 weeks (p &lt; 0.05), with higher flexion and supination at 3 months (p = 0.027) and 12 months (p = 0.003). Radiologically, VLPs showed improved parameters at 3- and 12-month follow-up. Overall complications did not significantly differ. Subgroup analysis in patients &lt; 60 years generally supported these findings, while in patients ≥ 60 years, radiological outcomes aligned, yet only lower DASH scores were observed with VLPs at 3 months (p &lt; 0.001). VLPs may offer superior clinical, functional, and radiological outcomes compared to cast immobilization at 3- and 12-month follow-up for patients &lt; 60 years, with comparable safety profiles. For patients ≥ 60 years, VLPs may yield better radiological outcomes at 3- and 12-month follow-up, though clinical benefits remain uncertain.

The Impact of Pronator Quadratus Origin Release on the Clinical Outcomes of Scaphoid Nonunion Patients Treated with Pronator Quadratus Pedicled Bone Grafts.

Background/Objectives: A pronator quadratus pedicled bone graft (PQPBG) is a distal radius volar vascularized bone graft used not only for avascular necrosis of the lunate but also for scaphoid nonunion. Despite its potency and its possession of a muscular shield, this vascularized graft has a disadvantage in that the potential shortness of the muscular leash may limit the distal transfer of the bone graft. Releasing of the pronator quadratus (PQ) ulnar origin was used to enhance the distal mobility of the graft. We aimed to investigate the effect of a PQ release on the surgical outcomes of scaphoid nonunions that were operated on with the PQPBG technique. Methods: Patients with scaphoid nonunion that were treated with PQPBG from 2009 to 2020 were reviewed. Patient demographic characteristics, surgical notes, physical examinations, and radiological evaluation data were collected. Wrist range of motion, grip strength, modified Mayo wrist score, and Quick-DASH score were used to evaluate the outcomes. The included patients were divided into two groups based on the origin release status of their PQ, i.e., with and without release. Results: This study included 37 patients, 17 of whom underwent a PQ release and 20 of whom did not. The failure rates for the two groups were one and four patients, respectively, and there was no significant difference between them (p = 0.11). The postoperative mean wrist extension in the patients with a PQ release was significantly greater than that in the patients without a release (43.5 ± 6.8 vs. 36.5 ± 7.7, p = 0.0038). Although wrist flexion, ulnar deviation, radial deviation, mean outcome assessment scores, and grip strength were greater in the patients with a PQ release than in those without, no statistically significant intergroup differences were observed (p > 0.05). Conclusions: The PQPBG technique is a viable option for achieving bony union in patients with scaphoid nonunion, but it results in the postoperative restriction of wrist extension. PQ release during a graft transfer may have a favorable effect on both bone union and clinical outcomes.

Comparative study of short-term effectiveness of three surgical methods for ulnar styloid base fracture complicated with triangular fibrocartilage complex injury

To compare the short-term effectiveness of arthroscopic suture of triangular fibrocartilage complex (TFCC), arthroscopic suture of TFCC combined with open reduction and internal fixation, and simple open reduction and internal fixation in the treatment of distal radius fractures combined with ulnar styloid base fractures and TFCC injury. A clinical data of 97 patients with distal radius fractures combined with ulnar styloid base fracture and TFCC injury, who were admitted between September 2019 and September 2022 and met the selective criteria, was retrospectively analyzed. After reduction and internal fixation of distal radius fractures, 37 cases underwent arthroscopic suture of TFCC (TFCC group), 31 cases underwent arthroscopic suture of TFCC combined with open reduction and internal fixation of ulnar styloid base fractures (combination group), and 29 cases underwent simple open reduction and internal fixation of ulnar styloid base fractures (internal fixation group). There was no significant difference in baseline data between groups ( P>0.05), such as gender, age, injury side, time from injury to operation, and preoperative radius height, palm inclination, ulnar deviation, grip strength, wrist range of motion (ROM) in rotation, ulnar-radial deviation, and flexion-extension. The differences (change value) in radius height, metacarpal inclination angle, ulnar deviation angle, grip strength, and wrist ROM in rotation, ulnar-radial deviation, and flexion-extension between preoperative and 12 months after operation in 3 groups were compared. The effectiveness was evaluated according to the modified Gartland-Werley score at 12 months after operation. All incisions healed by first intention. All patients were followed up 12-18 months (mean, 14 months). X-ray films showed that there were 4 patients with non-union of ulnar styloid base fracture in TFCC group, and the remaining patients had fracture healing at 3 months after operation. The radius height, palm inclination, and ulnar deviation of 3 groups at 12 months after operation were significantly better than those before operation ( P<0.05); however, the differences in the change values of the above indexes between groups was not significant ( P>0.05). At 12 months after operation, the change values of wrist ROM in rotation, ulnar-radial deviation, and flexion-extension in the TFCC group and the combination group were significantly greater than those in the internal fixation group ( P<0.05), and there was no significant difference between the TFCC group and the combination group ( P>0.05). The change values of grip strength was significantly greater in the combination group than in the internal fixation group ( P<0.05); there was no significant difference between the other groups ( P>0.05). The excellent and good rates according to the modified Gartland-Werley score were 91.89% (34/37), 93.54% (29/31), and 72.41% (21/29) in the TFCC group, the combination group, and the internal fixation group, respectively. The excellent and good rates of the TFCC group and the combination group were significantly higher than that of the internal fixation group ( P<0.05); there was no significant difference between the TFCC group and the combination group ( P>0.05). For ulnar styloid base fractures with TFCC injury, compared with simple open reduction and internal fixation, arthroscopic suture of TFCC or suture TFCC combined with internal fixation treatment are both beneficial for wrist function recovery, and their short-term effectiveness are similar. Therefore, arthroscopic suture of TFCC may be a better choice.

Introducing a Simple Tool of Patient Self-Assessment of Wrist Range of Motion.

Hand disorders can reduce wrist range of motion (ROM). The SARS-CoV-2 pandemic highlighted challenges in routine follow-up exams, making telemedicine a viable solution. This study evaluates the feasibility and accuracy of patient self-measured wrist ROM using a self-designed goniometer template. The template was designed to measure flexion/extension and radial/ulnar abduction movements. A cohort of 50 adults (25 males/25 females) participated in this prospective study. The exclusion criteria included wrist immobilization and ages outside of 18-65 years. Participants self-assessed their wrist ROM with the goniometer template. Measurements were independently performed by a student and a specialist using standard goniometry, as well as a resident using the self-designed goniometer. The results were blinded for unbiased analysis. Mean differences in ROM varied across movement directions, with minimal differences for ulnar abduction and more substantial deviations for radial abduction, extension and flexion. The patient-specialist comparison showed deviations below 5 degrees for flexion and ulnar abduction in 50% of cases. Telemedicine, expanded by the COVID-19 pandemic, offers significant potential for hand rehabilitation. Current methods of ROM assessment lack cost-effectiveness and simplicity. Our method, demonstrating comparable accuracy for most movements, provides a cost-effective, reliable alternative for remote ROM assessment, enhancing telemedicine practices in hand rehabilitation.

Long-term outcomes after capitate fractures: a median 16-year follow-up.

The long-term effects of a capitate fracture are unknown. The aim of this study was to assess both clinical and radiological long-term outcomes after a capitate fracture. From a cohort of 526 consecutive patients with post traumatic radial sided wrist pain, 23 were identified diagnosed with a capitate fracture. 16 of these (11 males and 5 females) with a median age at injury of 17.5 years (range 11-27 years) were eligible for a follow-up after a median of 16 years (range 8 to 17 years). In this study patients were examined using conventional radiographs, computed tomography (CT) and magnetic resonance imaging (MRI) at the time of injury and with CT at the follow-up. At follow-up radiological signs of osteoarthritis were graded in four stages and clinical outcome was evaluated by measuring range of wrist motion and grip and pinch strength. The subjective outcome was assessed using DASH and PRWE questionnaires. Five patients had isolated capitate fractures and 11 had concomitant fractures, 10 of which had a simultaneous scaphoid fracture. 14 patients had been treated non-surgically in a cast and two patients were treated surgically. None of the fractures were visible on conventional radiographs at the time of injury. At follow-up all fractures had healed without signs of avascular necrosis. In one patient, CT examination revealed osteoarthritis between the capitate and lunate. This did not cause clinical symptoms. Functional impairments and pain scores were low: median DASH score 0, median PRWE 3 and median VAS pain score 0. We found no impairment in range of motion or grip and pinch strength. At a median of 16-year follow-up, patients with a capitate fracture report normal self-assessed hand function as well as good wrist motion and strength. The risk of development of posttraumatic arthritis in the joints around the capitate is low.

Effect of dorsal capsular imbrication on intraoperative DRUJ instability following arthroscopic TFCC repair surgery

BackgroundTo assess the clinical outcomes and identify the ideal indication for implementing dorsal distal radioulnar joint (DRUJ) capsular imbrication after triangular fibrocartilage complex (TFCC) repair in cases of DRUJ instability.MethodsWe conducted a retrospective study on patients who underwent arthroscopic TFCC repair between 2016 and 2021. Inclusion criteria comprised a symptomatic ulna fovea sign for over 6 months and dorsal DRUJ subluxation on magnetic resonance imaging. A total of 225 patients were divided into two groups: Group 1 (135 cases) with a negative ballottement test after “Cross-form TFCC repair” (CR) and Group 2 (90 cases) with a positive ballottement test after “Cross-form TFCC repair” and augmented DRUJ stability through dorsal DRUJ capsular imbrication (CR + DCI). Pain visual analog scale score (VAS), grip strength, modified Mayo Wrist Score (MMWS), wrist range of motion (ROM), and patient-reported outcomes (PROMs) were assessed for a minimum of 3 years postoperatively.ResultsBoth groups showed significant improvements in pain VAS score, grip strength, wrist ROM, MMWS, and PROMs between the preoperative and postoperative periods (all P < 0.05). Recurrent DRUJ instability occurred in 3.7% and 1.1% of patients in the “CR” and “CR + DCI” groups, respectively, with a significant difference. Despite the “CR + DCI” group initially exhibiting inferior ROM compared with the “CR” group, subsequently, no significant difference was noted between them.ConclusionsDorsal DRUJ capsular imbrication effectively reduces postoperative DRUJ instability rates, enhances grip strength, and maintains wrist ROM in patients with a positive intra-operative ballottement test after arthroscopic TFCC repair.

Prophylactic Carpal Tunnel Release During Volar Plating of Distal Radius Fractures: A Review

PurposePatients who fracture their distal radius are at risk for developing carpal tunnel syndrome (CTS). Carpal tunnel syndrome occurs acutely; other patients may present with signs and symptoms of carpal tunnel syndrome weeks or months after the distal radius fracture. Because CTS may present in a delayed fashion after a distal radius fracture, some surgeons will perform carpal tunnel release in patients who undergo open reduction and internal fixation (ORIF) even in those patients who do not have clinical evidence of carpal tunnel syndrome – a prophylactic carpal tunnel release. In the current systematic review, we evaluated the literature regarding prophylactic carpal tunnel release in the setting of operative treatment of distal radius fractures. MethodsWe conducted our literature review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (Figure 1).1 The search strategy reflected “prophylactic carpal tunnel release during treatment of distal radius fractures,” and was conducted in February 2024. Included studies are summarized in Table 1. Results6 studies met inclusion criteria. Publication dates ranged from 2001 to 2018. 5 studies investigated clinical symptoms and/or electromyography: 3 out of 5 studies found worsening or persistent median neuropathy, and 2 out of 5 studies found improvement or no further development of symptoms in their respective patient cohorts. The 6th study found no difference in patient reported outcomes between either approach. ConclusionsThere were no differences in wrist range of motion, post-operative grip strength, or patient reported outcomes within each of the study cohorts. Based on the findings from the studies included in this review, we do not believe that there is sufficient evidence supporting prophylactic CTR in the setting of operative treatment of distal radius fractures.

Post-surgical Rehabilitation Guidelines for Triangular Fibrocartilage Complex Foveal Repair: A Survey of Australian Hand and Wrist Surgeons.

Background: To restore distal radioulnar joint stability following injury to the Triangular Fibrocartilage Complex (TFCC), foveal repair surgery may be necessary. Post-surgery rehabilitation is prescribed to restore wrist and hand function; however, no universally accepted or definitive rehabilitation protocol currently exists. The aim of this study was to survey hand and wrist surgeons regarding their recommended postoperative rehabilitation protocols following TFCC foveal repair surgery. Methods: Australian hand and wrist surgeons were invited to complete a descriptive survey containing 10 questions. Questions included clinical recommendations for wrist and forearm immobilisation, range of motion (ROM) exercise timeframes and surgeon experience of TFCC rupture. Descriptive statistics and between-group (TFCC rupture vs. no-rupture) comparisons (Pearson's Chi2) were calculated. Results: Thirty-one surgeons completed the survey. Recommendations for post-surgery immobilisation ranged from 'not required' to 8 weeks (mode 6 weeks). Wrist and forearm ROM commencement time ranged from 'immediately' to 'later than 8 weeks' (mode 6 weeks). The most recommended orthosis was a 'sugar-tong' (57%). Thirty-seven percent (37%) reported experience of post-surgery re-rupture. Conclusions: While surgeon recommendations varied, the majority recommended 4- to 6-week timeframe for immobilisation and ROM exercise commencement. Additional clinical research is recommended to evaluate whether postoperative rehabilitation decisions influence patient outcomes. Level of Evidence: Level V (Therapeutic).

Penatalaksanaan Fisioterapi Pada kasus Post ORIF Metacarpal IV Sinistra dengan modalitas Infra Red(IR) dan Terapi Latihan

Based on 2018 Riskesdas data, an average of 92,976 fractures occurred, totaling 5,144 people. A single trauma and sudden excess force can cause a fracture. Orif installation is carried out if the use of close reduction/plaster fails, Orif is installed on the right fracture fragment. In solving problems in post-orif cases, physiotherapy plays a role in restoring movement and function using infrared modalities and exercise therapy. The energy produced by IR can be absorbed by superficial tissue with a warm feeling, thereby reducing pain. Exercise therapy using active and passive body movements can increase the range of motion of joints, increase muscle strength values ​​to restore functional ability. This research method uses a case study of physiotherapy management in Post Orif Metacarpal IV cases with Infra Red (IR) and Exercise Therapy. Results were obtained such as pressure pain from T0:3 decreased to T6:1, movement pain T0:5 decreased to T6:1. The muscle strength value of left wrist flexor T0:3 increased to T6:5, extensor T0: 3 increased to T6: 5 in left wrist flexor T0: 3 increased to T6: 5, extensor T0: 3 increased to T6:4. Left wrist joint range of motion from T0 (S: 20°-0°-15°) increases to T6 (S: 50°-0°-50°) at T0 left mcp (S: 10°-0°-20°) increases to T6:(S:45°-0°-40°), functional activity from T0:(severe dependence) increases to T6:(light dependence). Being more careful in activities and not pushing your abilities can reduce the incidence of fractures.

High Rate of Union of Scaphoid Pseudoarthrosis Treated With Arthroscopic Olecranon Bone Graft Using Antegrade Percutaneous Headless Compression Screw

To assess the healing rate of scaphoid pseudoarthrosis treated with wrist arthroscopy, olecranon bone graft, and anterograde screw fixation, as well as evaluate complications and clinical and radiologic outcomes. All patients with scaphoid nonunion were selected between January 2017 and December 2022. Inclusion criteria were patients between 18 and 60 years of age, a diagnosis of scaphoid pseudoarthrosis, complete clinical patient-reported outcomes, radiographic measurements, and at least a 1-year follow-up. Scaphoid pseudoarthrosis was treated arthroscopically with olecranon bone graft and anterograde screw fixation. Clinical assessment was performed through visual analog scale (VAS) for pain, QuickDASH (Disabilities of the Arm, Shoulder, and Hand) questionnaire, wrist range of motion using a standard goniometer, and grip strength in kilograms with a Jamar hydraulic hand dynamometer. Clinical relevance was measured with the minimal clinically important difference (MCID) for VAS and QuickDASH. Scapholunate angle was measured. Union was assessed on a computed tomography scan. Seventeen patients were included with a mean follow-up of 17.2 months. The mean age was 30.1 years, and the average time from injury to arthroscopic surgery was 11.1 months. At latest follow-up, there was an improvement in VAS pain score and QuickDASH score. Range of motion and grip strength increased at last follow-up. MCID threshold for the VAS and QuickDASH score was reached by 100% and 94.1%, respectively. Union was achieved in 16 patients (94.1%) after a median of 16 weeks (interquartile range, 16-20). Arthroscopic treatment of scaphoid pseudoarthrosis with olecranon bone graft and antegrade percutaneous headless compression screw allows a high grade of union and improves pain and function at short-term follow-up. Level IV, therapeutic case series.

Evaluation of a cadaveric wrist motion simulator using marker-based X-ray reconstruction of moving morphology.

Surgical intervention is a common option for the treatment of wrist joint arthritis and traumatic wrist injury. Whether this surgery is arthrodesis or a motion preserving procedure such as arthroplasty, wrist joint biomechanics are inevitably altered. To evaluate effects of surgery on parameters such as range of motion, efficiency and carpal kinematics, repeatable and controlled motion of cadaveric specimens is required. This study describes the development of a device that enables cadaveric wrist motion to be simulated before and after motion preserving surgery in a highly controlled manner. The simulator achieves joint motion through the application of predetermined displacements to the five major tendons of the wrist, and records tendon forces. A pilot experiment using six wrists aimed to evaluate its accuracy and reproducibility. Biplanar X-ray videoradiography (BPVR) and X-Ray Reconstruction of Moving Morphology (XROMM) were used to measure overall wrist angles before and after total wrist arthroplasty. The simulator was able to produce flexion, extension, radioulnar deviation, dart thrower's motion and circumduction within previously reported functional ranges of motion. Pre- and post-surgical wrist angles did not significantly differ. Intra-specimen motion trials were repeatable; root mean square errors between individual trials and average wrist angle and tendon force profiles were below 1° and 2 N respectively. Inter-specimen variation was higher, likely due to anatomical variation and lack of wrist position feedback. In conclusion, combining repeatable intra-specimen cadaveric motion simulation with BPVR and XROMM can be used to determine potential effects of motion preserving surgeries on wrist range of motion and biomechanics.

Microwave-assisted intralesional curettage combined with other adjuvant methods for treatment of Campanacci III giant cell tumor of bone in distal radius: a multicenter clinical study.

To compare the clinical outcomes of microwave-assisted intralesional curettage(MAIC) with those of en bloc resection and autogenous fibular reconstruction (EBR-AFR) for treating grade III giant cell tumor of the bone (GCTB) of the distal radius and to elucidate the indications for wrist preservation surgery. In this retrospective study, 19 patients with grade III GCTB of the distal radius who underwent surgery at three medical institutions were included and categorized based on their surgical pattern. Seven patients underwent MAIC and internal fixation with bone cement (MAIC group) and 12 underwent EBR-AFR (EBR-AFR group). To evaluate the function of the affected limb postoperatively, wrist range of motion, grip strength, Musculoskeletal Tumor Society (MSTS) scores were recorded. The follow-up time of the MAIC group was 73.57 ± 28.61 (36-116) months, with no recurrence or lung metastasis. In contrast, the follow-up time of the EBR-AFR group was 55.67 ± 28.74 (36-132) months, with 1 case of local recurrence (8.3%, 1/12) and 1 case of lung metastasis (8.3%, 1/12). The wrist flexion, extension, supination, pronation, grip strength were better in the MAIC group than in the EBR-AFR group. Although there was no statistically significant difference in the MSTS score between the two groups, it is noteworthy that the MAIC group exhibited significantly superior emotional acceptance and hand positioning compared to the EBR-AFR group(p < 0.05). The functional outcomes of the MAIC group are better. The treatment strategy for grade III GCTB of the distal radius should be determined based on the specific preoperative imaging findings. Nevertheless, MAIC can be the preferred surgical approach for most patients with grade III GCTB of the distal radius, particularly for young patients.

What to Expect? Use of Supplemental Fixation With a Concomitant Dorsal Spanning Plate for Complex Intraarticular Distal Radius Fractures.

The dorsal spanning plate (DSP) is a versatile implant suitable for bridging severely comminuted intraarticular distal radius fractures [AO (Arbeitsgemeinschaft für Osteosynthesefragen) 23-C.1-C.3]. It may be used alone or with supplemental fixation such as a volar locking plate (VLP) or fragment-specific fixation (FSF). Outcomes following DSP fixation with additional implants have not been specifically evaluated. We retrospectively reviewed consecutive patients who underwent internal fixation of a distal radius fracture by a single surgeon from 2017 to 2021. Patients were grouped according to implants used: DSP only, DSP + FSF, and DSP + VLP. Preoperative variables, treatment times, and wrist range of motion (ROM) were assessed. Functional wrist ROM was defined as minimum 80° combined flexion and extension. One hundred fifty-two patients underwent surgery for wrist fracture, 33 of them were treated with a DSP: 8 DSP only, 6 DSP + VLP, and 19 DSP + FSF. Falls from height greater than 10 ft accounted for 52% of injuries, most of which were treated with a DSP + FSF. Treatment times and ROM were similar between subgroups. Wrist ROM did not improve significantly beyond 4 weeks following DSP removal. Overall, DSP patients recovered a mean wrist ROM of 85° (range 0°-130°) within a median 26 weeks total treatment period (range 12-68 weeks). Regardless of the construct used, if the distal radius articular surface is well reduced and other principles of fracture fixation are applied, most patients treated with a DSP can expect to regain functional wrist ROM. Level IV-Retrospective review of prospectively collected data.

Assessment of Pain Severity and Grip Strength as the Most Accurate Predictors of the Outcome of Treatment of Distal Radial Fractures.

Distal radial fractures are common injuries, accounting for approximately 25% of fractures in the paediatric population and up to 18% of all fractures in the elderly age group. Assessment of treatment outcomes of these fractures includes objective measurements of wrist joint range of motion and grip strength as well as subjective parameters such as the intensity of perceived pain, hand function and quality of life. The recent years have ushered in a trend towards using several outcome measures for a more comprehensive evaluation of the results of the treatment. The objective of this study was to investigate whether the assessment of pain severity and grip strength is sufficiently accurate for correct assessment of the outcome of the treatment of distal radial fractures. One hundred and two patients, 79 women (77%) and 23 men (23%), at a mean age of 54 years with distal radial fractures were treated operatively. Treatment outcomes were assessed at 3 and 6 months by measurements of intensity of pain (according to a numerical rating scale, NRS), grip strength (with a dynamometer) and hand function with the DASH questionnaire. The results of these measurements were compared in order to investigate the strength of the possible correlation between variables. An analysis of the correlation between the variables of interest at 3 and 6 months' assessment showed statistically significant correlations (Spearman rank test, R=0,26-0,41; p&lt;0,01). The NRS correlated negatively with grip strength (less pain - greater strength) and positively with DASH scores (less pain - better hand function). The correlation between grip strength and the DASH was the strongest (Spearman rank test R=0,61; p&lt;0,001, showing that greater power of the hand indicated better function, whereas weaker grip indicated worse function. 1. The severity of pain and the degree of weakness of the hand show (independently of each other) a very good correlation with the comprehensive assessment of hand function using the DASH questionnaire. 2. It follows that pain severity and hand weakness are sufficient to reliably assess the outcome of the treatment of a distal radius fracture.

The Validity and Reliability of a Smartphone Application for Measuring Wrist and Metacarpophalangeal Joint Motion.

Background Accurate measurement of the range of motion (ROM) is crucial for guiding upper extremity rehabilitation. Inaccurate measurements can mislead clinicians and harm patient compliance. This study aimed to evaluate the validity and reliability of a smartphone application (Angulus) for measuring wrist and metacarpophalangeal (MCP) joint ROM. Methodology This study included 64 volunteers with no prior wrist injuries. Thewrist flexion/extension, radial/ulnar deviation, and MCP joint flexion/extension ROM were assessed by an experienced physiotherapist (Assessor 1) using the Angulus and a standard two-arm goniometer. The validity of Angulus was evaluated by correlating it with the goniometer measurements using the Pearson correlation coefficient. For the reliability analysis, an inexperienced biomedical engineer (Assessor 2) performed the same measurements using Angulus twice in different sessions, in addition to Assessor 1. The intra-rater and inter-rater reliability were tested using the intraclass correlation coefficient. Results The mean age of the participants was 29.5 ± 8.2 years, with 62% being female. The validity of the Angulus app measurements was indicated by the adequate to excellent correlation between the Angulus and goniometer measurements (ranging from 0.44 to 0.81). The intra-rater reliability of the Angulus app was excellent for Assessor 1 (ranging from 0.76 to 0.90) and adequate to excellent for Assessor 2 (ranging from 0.71 to 0.88). The inter-rater reliability of Angulus was excellent (ranging from 0.91 to 0.96). Conclusions Angulus is a valid and reliable method to measurethe wrist and MCP joint ROM.

OPEN REDUCTION AND INTERNAL FIXATION WITH PLATING VERSUS EXTERNAL FIXATOR IN DISTAL END RADIUS FRACTURES: A COMPARATIVE STUDY

Objectives: The purpose of this study is to compare the external fixation and locking plate fixation of intraarticular fractures of the distal radius in terms of functional outcome and complications. The study aims to assess the patients for fracture union, wrist range of motion (ROM), grip strength, pain, and activity among the locking plate and external fixator group. Methods: This study aimed to compare distal end radius external fixator to distal end radius plating regarding functional outcomes. This is an observational type of study where 40 patients were included in the study, among them, 20 were treated with external fixator/k wire and 20 with distal radius plate. The study was conducted in a tertiary care institute during the study period. Results: The most patients were males &gt;50 years of age, with injury caused by a fall on an outstretched hand. In the present study, we got excellent functional results according to the G and O’Brien system in 11 (55%) of patients treated with the plating group, good results in 5 (25%), fair results in 4 (20%), and poor (0%) in the plating. Conclusion: Plating provides better functional outcomes, as assessed by Green and O’Brien’s score, as compared to external fixation. It allows for an early post-operative ROM exercises compared to an external fixator and better anatomical positioning of the fracture segments.

Free hemi-hamate arthroplasty: A review of donor site outcomes

IntroductionThe use of the dorsal hamate as a free osteochondral bone graft or vascularized bone flap has become the mainstay for large, comminuted middle phalanx volar lip fractures. To date, few studies have been conducted in the assessment of donor site morbidity for the hemi-hamate graft or flap, and none have discussed modes of repair or reconstruction of this donor site. MethodsA retrospective analysis of 14 hemi-hamate arthroplasty (HHA) procedures, including 6 vascularized and 8 non-vascularized grafts, from two surgeons was performed. Four hamate defect reconstruction techniques were utilized: no formal reconstruction, autologous bone grafting, gel foam, or synthetic bone substitute. The dorsal capsule was repaired with either extensor retinaculum grafting or by direct closure. Wrist range of motion, pain scores, and radiographic alignment were assessed. ResultsAt 6 months follow-up, all patients achieved full, pain-free wrist motion compared to the uninjured side, with visual analog scale pain scores of 0. Serial radiographs showed maintained carpal alignment without instability or subluxation. No differences based on the hamate defect reconstruction method or capsular repair technique was demonstrated. ConclusionSafe return to pain free, unrestricted wrist function is achievable after HHA, regardless of hamate donor site management. Adequate dorsal capsular repair appears critical to prevent instability. Further study is needed to compare techniques, but choice may be guided by surgeon preference in the absence of clear evidence.
