Median Nerve Neuropathy Caused by Persistent Median Artery Thrombosis.

Persistent median artery thrombosis mimicking carpal tunnel syndrome is rare. Here, we report the pathological, ultrasonography, and intraoperative findings of a case of persistent median artery thrombosis mimicking carpal tunnel syndrome. A 34-year-old man reported to our clinic with a complaint of numbness in his left thumb, index finger, and middle finger, which are innervated by the left median nerve.

Modified Posterior Trans-olecranon Approach in Tri-vision for Dubberley Type 3B Coronal Shear Fractures of the Distal Humerus.

Coronal shear fractures are rare injuries and standard treatment is yet to be determined. There is still no standard approach and fixation method for Dubberley type 3B cases, which are severe fractures that extend to the ulnar side and are accompanied by posterior comminution, making them challenging injuries. We used a modified posterior trans-olecranon approach in tri-vision in the supine position in two type 3B cases.

Outcomes of Rerouting the Palmaris Longus to Extensor Pollicis Longus Tendon Transfer through the Second Extensor Compartment for Radial Nerve Palsy.

A palmaris longus (PL) to extensor pollicis longus (EPL) is a standard tendon transfer used to restore thumb extension in patients with radial nerve palsy. This transfer is done by withdrawing the EPL from the third compartment and passing it subcutaneously to reach the PL. We modified this transfer by rerouting the EPL through the second extensor compartment to improve the retropulsion of the thumb.

Interosseous wiring for fragmented proximal phalangeal fractures.

Fragmented proximal phalangeal fractures are difficult to treat. Fixation with plate and screws often lead to contractures and extensor tendon adhesions. Interosseous wiring could prevent those complications by repairing the periosteum and avoiding direct contact between implants and extensor tendon, while a good total active motion can be achieved.

Effectiveness of ultrasonographic evaluation under general anesthesia for radial nerve palsy associated with humeral fractures during the first operation.

Purpose: To evaluate the effectiveness of sonographic evaluation of the radial nerve at the first operation for closed humeral fracture cases.

Methods: Seventeen cases of closed humeral fractures were included in this study. These cases were categorized into two groups: Group P, consisting of seven cases with complete radial nerve palsy after the injuries; and Group C, consisting of ten cases without radial nerve palsy after the injuries.

The effectiveness of distraction lengthening in traumatic hand amputation with Ilizarov mini fixator.

Background: Bone distraction lengthening has been used for hand reconstruction. The healing process involved in this technique is affected by many factors. Here, the effectiveness and rates of healing of the phalanges and the metacarpals were evaluated in cases of traumatic finger amputation treated using an Ilizarov mini-fixator.

Evaluation of intramedullary nail fixation via the Neviaser portal for proximal humerus fracture.

Objectives: To our knowledge, no cases have been reported so far regarding the treatment of proximal humerus fracture with intramedullary nail fixation via the Neviaser portal. This study aimed at evaluating the results of intramedullary nail fixation via the Neviaser portal for proximal humerus fracture.

Methods: Four patients with 2-part proximal humerus fracture, who underwent the intramedullary nail fixation via the Neviaser portal, were included in this study.

Efficacy and safety of novel collagen conduits filled with collagen filaments to treat patients with peripheral nerve injury: A multicenter, controlled, open-label clinical trial.

Introduction: The safety and efficacy of using artificial collagen nerve conduits filled with collagen filaments to treat nerve defects has not been fully studied in humans. We conducted a multicenter, controlled, open-label study to compare the safety and efficacy of artificial nerve conduit grafts with those of autologous nerve grafts.

Methods: We included patients with a sensory nerve defect of ≤30 mm, at the level of the wrist or a more distal location, with the first-line surgical methods selected according to a patient's preference.

Corrective Osteotomy of Malunited Diaphyseal Fractures of the Forearm Simplified Using 3-Dimensional CT Data: Proposal of Our Simple Strategy Through Case Presentation.

Background: Reconstruction of malunited diaphyseal fractures of the forearm is one of the most difficult treatments due to its complicated structure. Widespread usage of Digital Imaging and Communications in Medicine (DICOM) data of 3-dimensional (3D) computed tomography (CT) and 3D printing can make estimating the true plane of the deformity easy.

Methods: A 21-year-old man with limited supination due to left forearm nonunion deformity initially treated by locking plate fixation was referred to our hospital.

Evaluation of flexor pollicis longus tendon attrition using color Doppler imaging after volar plate fixation for distal radius fracture.

Purpose: Early diagnosis of attritional wear of the flexor pollicis longus (FPL) tendon is essential in preventing subsequent tendon rupture. There are currently few objective methods of assessing FPL attrition. We hypothesized that color Doppler imaging could visibly detect FPL tendon attrition, and analyzed our results.

Clinical outcomes and prognostic factors depending on implant design in the treatment of proximal humeral fractures: A retrospective study.

Purpose: We aimed to examine the clinical outcomes of proximal humeral fractures treated with different intramedullary nail shapes.

Methods: Thirty-seven patients were divided into two groups depending on the implant shape. We also defined F group as a subgroup of fracture classification.

Sonographic evaluation of effects of the volar plate on trigger finger.

Background: We evaluated trigger fingers ultrasonographically and clarified differences between fingers with and without continuous locking or snapping symptoms according to the thicknesses of the A1 pulley, flexor tendon and volar plate.

Methods: We evaluated 26 trigger fingers, divided into two groups: Group 1, 14 fingers with locking or snapping; and Group 2, 12 fingers without such symptoms. We also evaluated 26 contralateral fingers as controls (Control 1 and 2 groups).

Reliability of the Hand20 questionnaire: comparison with the 36-Item Short-Form Health Survey.

Background: Hand20 is an illustrated, self-administered questionnaire comprising 20 short and easy-to-understand questions to assess upper limb disorders. This study aimed to test the reliability, validity, and responsiveness of Hand20.

Methods: Eighty-five patients with three upper limb disorders (51 with trigger finger, 29 with ulnar impaction syndrome, and five with carpal tunnel syndrome) completed Hand20, the Japanese Society for Surgery of the Hand version of the Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH-JSSH), and the 36-Item Short-Form Health Survey (SF-36).

Responsiveness of the Japanese version of the patient-rated wrist evaluation (PRWE-J) and physical impairment measurements in evaluating recovery after treatment of ulnocarpal abutment syndrome.

Background: We evaluated the responsiveness of patient-derived questionnaires and physical findings in evaluating recovery after treatment of ulnocarpal abutment syndrome.

Methods: Patients were assessed at their initial visit to our clinic and again 3 months after the treatment. At each visit, patients completed a Short Form-36, the Japanese Society for Surgery of the Hand version of Disability of the Arm, Shoulder, and Hand questionnaire (DASH-JSSH), and the Japanese version of patient-rated wrist evaluation (PRWE-J).

Reliability, validity, and responsiveness of the Japanese version of the Patient-Rated Wrist Evaluation.

Background: The Patient-Rated Wrist Evaluation is a regionspecific, self-administered questionnaire consisting of a pain scale (PRWE-P) and a functional scale (PRWE-F), with the latter consisting of specific function (PRWE-SF) and usual function (PRWE-UF). The PRWE was cross-culturally adapted from the original English version by the Impairment Evaluation Committee, Japanese Society for Surgery of the Hand (JSSH). The purpose of this study was to test the reliability, validity, and responsiveness of the Japanese version of PRWE (PRWE-J).
