This study proposes a Deep Learning algorithm to automatically detect perilunate dislocation in anteroposterior wrist radiographs. A total of 374 annotated radiographs, 345 normal and 29 pathological, of skeletally mature adolescents and adults aged ≥16 years were used to train, validate and test two YOLOv8 deep neural models. The training set included 245 normal and 15 pathological radiographs; the pathological training set was supplemented by 240 radiographs obtained by data augmentation. The test set comprised 30 normal and 10 pathological radiographs. The first model was used for detecting the carpal region, and the second for segmenting a region between Gilula’s 2nd and 3rd arcs. The output of the segmentation model, trained multiple times with varying random initial parameter values and augmentations, was then assigned a probability of being normal or pathological through ensemble averaging. In the study dataset, the algorithm achieved an overall F1-score of 0.880: 0.928 in the normal subgroup, with 1.0 precision, and 0.833 in the pathological subgroup, with 1.0 recall (or sensitivity), demonstrating that diagnosis of perilunate dislocation can be improved by automatic analysis of anteroposterior radiographs.

Objectives

This study aimed to report surgical technique and clinical outcomes for a novel figure-of-eight collateral ligament reconstruction technique using palmaris longus autograft for chronic irreparable collateral ligament injury of the thumb metacarpophalangeal joint.

Material and methods

The Jobe elbow collateral ligament reconstruction method was adapted for thumb metacarpophalangeal joint collateral ligament reconstruction. Sixteen reconstructions (7 ulnar collateral ligament, 9 radial collateral ligament) using palmaris longus autograft were reviewed retrospectively. Surgery was performed at a mean 12 months post-injury. All 16 patients were followed up for more than 1 year. Metacarpophalangeal joint radial and ulnar deviation, metacarpophalangeal and interphalangeal joint range of motion, key pinch and grip strength, Glickel functional grade and QuickDASH score were evaluated.

Results

Preoperative radial or ulnar deviation improved from 19.3° to 5.3° postoperatively. Metacarpophalangeal range of motion improved from 31.5° to 46.6°, and interphalangeal range of motion from 48.4° to 65.6°. Preoperative key pinch and grip strength were respectively 49% and 81% of contralateral values and improved to 82% and 87%. On Glickel grade, 9 cases were excellent and 7 good.

Conclusion

The novel Jobe-like figure-of-eight reconstruction technique using palmaris longus graft was useful for reconstructing irreparable thumb metacarpophalangeal joint instability without an incision on the opposite side or an additional implant.

Introduction

Forearm chronic exertional compartment syndrome is a rare condition in athletes and musicians who perform repeated prolonged forced gripping movements. It mainly affects young men, and presents with cramp-like pain, beginning on the anteromedial side of the forearm and progressively extending to the entire circumference, and may be associated with muscle weakness and neurologic symptoms. The objective of this study was to report preliminary results of ultrasound-guided fasciotomy in the treatment of forearm chronic exertional compartment syndrome.

Material and methods

A single-center retrospective observational study was conducted. Forearm chronic exertional compartment syndrome was diagnosed on clinical presentation and pathological intramuscular pressure measurement, defined as >30 mmHg at 1 min after effort. The series comprised 7 men, with bilateral involvement. Mean age was 30 years. All patients were motorcyclists. The mean preoperative intramuscular pressure at 1 min after effort was 60.75 mmHg (range: 30−81 mmHg). The main study endpoint was change in pain on visual analogic scale. Secondary endpoints comprised patient satisfaction, change in competitive sports level, and time to return to sport. Complications were noted.

Results

Six patients (12 forearms) were evaluated. Mean follow-up was 22.5 months (range: 3–48 months). Mean pain rating was 7.3/10 (range: 6–9) preoperatively, and 0/10 postoperatively. All patients were satisfied with the procedure. Mean time to return to sports was 25.5 days (range: 21–30 days). No patients decreased their competitive sports level after the procedure. One patient presented a postoperative hematoma, not requiring surgery.

Conclusion

Ultrasound-guided fasciotomy in the treatment of Forearm chronic exertional compartment syndrome is an innovative technique with promising preliminary results.

Open reduction with internal fixation is a common approach for treating distal radius fractures. However, complications such as extensor tendon rupture can occur following this procedure. In this case report, we present a patient who experienced extensor tendon rupture following volar plate fixation of a distal radius fracture. The rupture was diagnosed preoperatively using ultrasound. We highlight the potential usefulness of ultrasound as a convenient and sensitive tool for diagnosing tendon injuries in patients with suspected complications following internal fixation of distal radius fractures. Furthermore, we discuss how ultrasound images can aid in localizing the site of tendon rupture and guide surgical incisions for smaller postoperative wound care, resulting in improved cosmetic outcomes.

Trigger finger is a common condition. Surgery most frequently involves opening the A0 and A1 pulleys. However, this shows limited effectiveness in correcting proximal interphalangeal joint fixed flexion deformity. The present study aimed to compare clinical outcomes between two surgical techniques for trigger finger treatment.

This retrospective study included 127 patients, 72 of whom underwent resection of the ulnar slip of the flexor superficialis, and 55 underwent opening of the pulleys. Study data comprised patient characteristics, range of motion, proximal interphalangeal fixed flexion deformity measurement, Quick-DASH and PRWE scores, and overall satisfaction.

There were no significant differences between the two groups in terms of Quick-DASH or PRWE scores. Fixed flexion deformity correction was slightly but not significantly better with resection of the ulnar slip of the flexor superficialis (100%) compared to opening of the pulleys (88%).

This systematic review aims to provide a comprehensive synthesis and in-depth analysis of the quality of the different cross-cultural versions of the MHQ. This study was conducted using Pubmed, Web of Science, CINAHL and SCOPUS databases to identify cross-cultural validation studies of the MHQ. Methodological quality, quality of evidence and criteria for good measurement properties of these studies were applied for each psychometric property. Quality assessment and data extraction were performed independently by two reviewers according to the COnsensus-based Standards for selection of health Measurement INstruments (COSMIN) guidelines. A total of 493 articles were identified, of which 22 were included and 20 were analysed.Of the six properties analysed, responsiveness and hypothesis testing for construct validity had the highest methodological quality and quality of evidence, and met the criteria for good measurement properties. The lowest quality properties were measurement error and internal consistency. The different cross-cultural versions of the MHQ were found to be reliable, valid and able to detect clinical change. The lack of development of measurement error, formulation of an a priori hypothesis or structural validity affects the detection of small clinical changes and their discriminative capacity.

Background

Trigger finger is one of the most frequent causes of hand pain and disability. Recently, an endoscopic trigger finger release technique was developed, but outcomes have rarely been reported. Here, we present the outcomes of 2154 endoscopic trigger finger release procedures in a single center.

Methods

In this retrospective study, 2154 endoscopic trigger finger release procedures were performed on 2034 patients. Outcome assessment at 90 days after surgery was classified as excellent, good, fair or poor according to a combination of patient satisfaction with the scar and pain at rest or under load on a numeric rating scale.

Results

The therapeutic outcomes were: 1027 excellent, 607 good, 400 fair, and none poor. No major surgical complications were observed. Minor complications occurred in 231 fingers (10.7%).

Conclusions

All patients were satisfied with their outcome after endoscopic trigger finger release. Endoscopic release can be an effective and efficient therapeutic method for the treatment of trigger finger.

Objective

De Quervain's tenosynovitis causes pain and impairment of thumb function. Conservative treatments comprise corticosteroid injection and immobilization, and it is unclear which offers greater efficacy. Previous reviews were limited by the small number of included studies; thus an updated review and meta-analysis is warranted.

Methods

A systematic review of the PubMed, Embase, and Web of Science databases was conducted. Randomized control trials comparing corticosteroid injection to immobilization were included. Two authors screened articles, extracted data, and assessed the risk of bias of included studies. Meta-analyses using the random-effects model were conducted, calculating pooled relative risks and mean differences with 95% confidence intervals.

Results

16 studies comprising 1206 patients were included. Corticosteroid injection showed greater treatment success than immobilization (relative risk: 1.61; 95% confidence interval: 1.21–2.15). Combining treatments demonstrated greater efficacy than immobilization (relative risk: 2.15; 95% confidence interval: 1.77–2.62) or injection alone (relative risk: 1.23; 95% confidence interval: 1.12–1.34). Pain and disability scores were lower with injection than immobilization and with combined treatment than with either alone.

Conclusion

Corticosteroid injection is more effective than immobilization for De Quervain's tenosynovitis, and combining the two treatments provides additional benefit. We recommend corticosteroid injection in first line treatment and immobilization as adjuvant therapy. Further research is required regarding optimal corticosteroid and local anesthetic formulations.

Introduction

Handgrip strength (HGS) is a strong predictor and easily applicable assessment, indicating a person's physical condition and health. However, many dynamometers are available; therefore, it is essential to ensure that the results of HGS testing using different dynamometers can be used interchangeably. The primary purpose of this study was to investigate the inter-instrument agreement and criterion validity of the Baseline BIMS Digital Grip Dynamometer in comparison with the Jamar electronic dynamometer (Jamar+).

Methods

Seventy participants, aged between 23–88 (five men and five women in each decade from 20 to 80+), performed three attempts with each dynamometer (30-sec break between attempts) in a randomized order and separated with a 5-minute break between dynamometers. Intraclass correlation coefficient (3.1), standard error of measurement and minimal detectable change were used for comparison of the strongest and average strength measured with dynamometers. Jamar+ and Baseline BIMS Digital Grip Dynamometer were new dynamometers and considered calibrated by the manufacturer.

Results

The overall Intraclass correlation coefficient was excellent (0.98). An average (SD) difference of 0.68 (2.2) kg (p = 0.04) was seen for the comparison of the strongest attempt for Baseline BIMS minus Jamar+, Correspondingly, for the average of three attempts, it was 0.37 (2.29, p = 0.2) kg. The standard error of measurement (%) and minimal detectable change (%) of the strongest attempt was 1.64 kg (4.2%) and 3.55 kg (9.0%), respectively.

Conclusions

Findings indicate low measurement error with high agreement and criterion validity for the comparison of Baseline BIMS Digital Grip Dynamometer and Jamar+ and that results of the two dynamometers can be used interchangeably.

A 32 year-old climber sustained a grade IV frostbite injury to the right hand which required amputation at the neck of the proximal phalanges of all the long fingers. To increase range of motion and strength in the remaining metacarpophalangeal joints, tenodesis of the flexor digitalis superficialis and profundus tendons onto the proximal phalanges was performed. Several revisions for removal of bony spurs, dorsal skin advancement flaps and web space deepening were necessary. After 2 years, the patient achieved 10-0-100° metacarpophalangeal joint range of motion in extension-flexion and could do full body-weight pull-ups on 1 cm deep holds, lift 50 kg on a 2 cm deep hold (normal contralateral side, 40 kg), climb up to F7a routes and use a mechanical 4-finger functional prosthesis.
