Clinical characteristics and results after conservative treatment or interfascicular neurolysis of 100 limbs with spontaneous anterior interosseous nerve palsy: A prospective Japanese multicenter study.

Background: Spontaneous anterior interosseous nerve (AIN) palsy is characterized by the sudden onset of upper limb pain followed by weakness of muscles mainly innervated by the AIN. Although this palsy is conventionally treated conservatively, interfascicular neurolysis to release hourglass-like fascicular constrictions has been recommended. The present study aimed to establish the clinical characteristics and treatment strategy for this condition.

Limited Flexion of the Middle Finger Due to a Degenerative Partial Flexor Tendon Rupture Mimicking a Soft Tissue Tumor.

Atraumatic subcutaneous rupture of the finger flexor tendon of the hand and forearm is rare. Most sites of closed and subcutaneous ruptures of the finger flexor tendon are the tendon-bone insertion and musculotendinous junction, and an intratendinous lesion is unusual. We report the case of a 76-year-old female who presented to our department with a one-month history of a soft tissue mass and limited flexion of the left middle finger without trauma.

Wide-Awake Tenolysis for Tendon Entrapment in a Distal Radial Epiphyseal Separation (Volar Displacement Type): A Case Report.

The patient was a 13-year-old male who fell while riding a bicycle and was initially diagnosed with a distal radial epiphyseal separation (volar displacement type) that was conservatively managed. Four months post-injury, he complained of limited movement in his left index finger and was referred to our hospital. Upon examination, the patient also complained of limited movement of the left index finger in wrist flexion.

Surgical treatment for acute longitudinal radioulnar dissociation with humeral capitellar fracture: A case report.

Background: The forearm connects the wrist and elbow joints, and its stability depends on the two articulations, the proximal and distal radioulnar joints, and the interosseous membrane complex. The aim of this case report is to present an acute case of longitudinal radioulnar dissociation with humeral capitellum fracture.

Case Presentation: A 48-year-old man suffered longitudinal radioulnar dissociation with humeral capitellar fracture following a motorcycle accident.

Carpal Tunnel Syndrome Caused by a Juxta-articular Myxoma: A Case Report.

Juxta-articular myxoma (JAM) is a rare soft tissue tumour predominantly composed of mucinous tissue and usually found around large joints. We report a 73-year-old woman with a 5-year history of a soft tissue mass in the thenar eminence of the right wrist who presented to our department. An initial diagnosis of a ganglion cyst was made using magnetic resonance imaging (MRI) and the jellied content of the mass by aspiration.

Peripheral nerve regeneration by bioabsorbable nerve conduits filled with platelet-rich fibrin.

Purpose: To repair peripheral nerve defects and seek alternatives for autografts, nerve conduits with various growth factors and cells have been invented. Few pieces of literature report the effect of nerve conduits plus platelet-rich fibrin (PRF). This study aimed to investigate the effectiveness of nerve conduits filled with PRF.

Computed Tomography Evaluation of Distal Screw Penetration in Volar Locking Plate Fixation for Intra-Articular Distal Radius Fractures.

Purpose: Volar locking plate fixation for distal radius fractures (DRFs) is a technically demanding procedure with a risk of distal screw penetration through the dorsal cortex or the articular surface. This study aimed to investigate the incidence and details of distal screw penetration after volar locking plate fixation for intra-articular DRFs using a CT scan and to evaluate the relationship between the incidence of screw penetration and fracture comminution severity and the clinical complications of screw penetration.

Methods: This was a retrospective case series of 91 adult patients (mean age, 63 years; 27 men) who underwent volar locking plate fixation for intra-articular DRFs from 2015 to 2018.

Clinical Results of Surgical Treatment for Comminuted Radial Head and Neck Fracture: Headless Compression Screws Versus Plate Fixation.

Background: We surgically treated comminuted radial head and neck fractures using headless compression screws, including multiple screws for the radial head and a single oblique screw for the radial neck. This study aimed to compare the clinical and radiological results for comminuted radial head and neck fractures between surgery using headless compression screws with a single oblique screw for the radial neck, our new procedure, and a plate system precontoured to the proximal radius.

Methods: This retrospective study included 23 patients (11 and 12 in the screw and plate groups, respectively).

Examination on Factors Affecting Symptom Change after Drug Withdrawal in Patients with Mild Erosive Gastroesophageal Reflux Disease Undergoing Symptom-Controlled Maintenance Therapy with Acid-Secretion Inhibition Drugs.

Introduction: In patients with gastroesophageal reflux disease (GERD) on maintenance therapy with acid-suppressive drugs, it is not clear what background factors allow patients to discontinue the drugs. The aims of this study were to examine the relationship of the changes in the frequency and severity of gastrointestinal symptoms after discontinuation of acid-secretion inhibitors for erosive GERD (eGERD) with possible patient background factors and to identify factors that influence these changes.

Methods: This is a multicenter, open-label, interventional, exploratory study.

Arthroscopic Reduction and Internal Fixation for Peritrapezium Traumatic Axial Carpal Dislocation: A Case Report.

Axial carpal dislocations and fracture-dislocations are rare injuries involving derangement of the carpal arches. Several surgical approaches have been reported as a means of treatment, including the use of closed or open reduction and internal fixation. However, to our knowledge, surgical treatment using arthroscopy has not been reported so far.

Nerve-End Capping Treatment with a Polyglycolic Acid Conduit for Rat Sciatic Neuroma: A Preliminary Report.

Background:  The treatment of painful neuroma remains challenging. Recently, a nerve-end capping technique using a bioabsorbable nerve conduit was newly introduced to treat amputation neuroma. A collagen-coated polyglycolic acid (PGA) conduit has been commercially available for the reconstruction of peripheral nerve defects, yielding successful clinical outcomes.

Simultaneous Open Reduction and Corrective Osteotomy for a Child With Lateral Condylar Fracture and Cubitus Varus Deformity Following Supracondylar Fracture: A Case Report.

Posttraumatic cubitus varus deformity in pediatric patients may cause second fractures of the distal humerus. Corrective osteotomy is used to obtain good alignment and is generally performed for patients with prolonged deformity or bony union after fracture. We report the case of a 10-year-old boy who presented with elbow pain after falling.

Nerve Grafting for Isolated Injury to the Intrinsic Motor Branch of the Ulnar Nerve due to a Stab Injury: A Case Report.

Isolated injury to the deep motor branch of the ulnar nerve caused by stabbing is sporadic, with only one reported case in the English-language literature. We report one such case treated successfully using nerve grafting. A 33-year-old patient had sustained a stab wound to the right hypothenar eminence and showed a claw hand deformity.

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.

Microvascular neural blood flow assessment for a chronic nerve compression neuropathy mouse model by fluorescein angiography.

Background And Aims: Intraoperative fluorescence angiography with indocyanine green or fluorescein is used in ophthalmology and neurosurgery. However, there are few reports on the use of fluorescence angiography for peripheral neuropathy. This study aimed to assess the validity of fluorescein angiography (FAG) for peripheral nerve entrapment neuropathy.

Is Repair of a Small Coronoid Fracture Required in the Surgical Treatment of Terrible Triad Injury of the Elbow?

Multiple treatment protocols have been described in literature for the treatment of terrible triad injury (TTI) of the elbow. We believe that repair of the medial collateral ligament (MCL) should be performed in preference to repair of a small coronoid fracture if the elbow is unstable after fixation/replacement of the radial head and repair of the lateral collateral ligament (LCL). The aim of this study is to report the outcomes of surgical treatment of patients with TTI associated with a small coronoid fracture in whom the coronoid fracture was not addressed.

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.

Sequential Clinical Recovery after Replantation for Complete Finger Amputation in Tamai Zone 1.

 The clinical results of replantation for an amputated distal finger are functionally acceptable. However, few reports exist regarding sequential clinical postoperative recovery. The purpose of this study was to examine the clinical recovery at every 3 months up to 1 year postoperatively.

High Median Nerve Entrapment by Fracture Callus in Surgically Treated Pediatric Supracondylar Humeral Fracture: A Case Report.

Case: We describe a patient with incomplete high median nerve palsy after surgical treatment of pediatric supracondylar humeral fracture (SCHF). Preoperative images after 11 months after the surgical treatment of the SCHF showed rotational deformity and an isolated median nerve entrapped between the proximal humerus anteriorly and callus posteriorly in the bony tunnel of the distal humerus. Two years after neurolysis, he showed clinical recovery.

Endoscopic resection of tendon xanthoma in the elbow of a patient with cerebrotendinous xanthomatosis.

We describe the case of a 44-year-old woman with cerebrotendinous xanthomatosis (CTX) who had a tendon xanthoma on the right olecranon. The patient successfully underwent endoscopic resection. There were no signs of recurrence on MRI 2 years postoperatively.
