Post-traumatic entrapment of the median nerve in the ulno-humeral joint: Diagnosis, treatment and literature review.

Background: The incidence of median nerve injuries in pediatric elbow dislocations is approximately 3% and avulsion of the open medial epicondylar epiphysis in the pediatric population is one predisposing factor that may explain this age predilection. These lesions can be difficult to diagnose in the acute phase because symptoms tend to be mild or delayed, consequently their management can be challenging and functional outcome poorer.

Methods: We present the case of an unrecognized median nerve entrapment in a 16-year-old boy with posterior dislocation of the elbow and a medial epicondyle fracture, treated initially with close reduction and open stabilization with a cannulated screw.

Four-Corner Arthrodesis Using a Dedicated Dorsal Circular Plate.

Background: Scaphoid excision and 4-corner fusion is a standard procedure for advanced carpal collapse. The purpose of this study was to evaluate its effectiveness using a specific designed locking plate of the latest generation.

Methods: Between October 2012 and December 2015, 12 patients underwent this procedure using the Flower (KLS Martin Group, Tuttlingen, Germany) circular locking plate.

Proposal for Treatment of Severe Dupuytren Disease in 2 Steps: Progressive Distraction With External Fixator and Collagenase - A Preliminary Case Series.

We want to describe a treatment for advanced Dupuytren disease using a spanning external fixator (EF) applied dorsally to produce progressive extension, followed by collagenase injection. Between October 2014 and September 2016, a total of 22 fingers from 18 patients were treated with an EF. The devices were implanted under local anesthesia, and the patients were instructed to gradually extend the hinge to gain a progressive extension.

Trapeziometacarpal osteoarthritis: pyrocarbon interposition implants.

Purpose: the aim of this study was to evaluate the effectiveness of interposition arthroplasty of the trapeziometacarpal (TMC) joint with pyrolitic carbon implants for the treatment of TMC osteoarthritis.

Methods: we evaluated two groups of patients surgically treated for TMC osteoarthritis: group 1 (34 patients - 36 TMC joints) treated with PyroDisk implantation and group 2 (25 patients - 25 TMC joints) treated with the Pyrocardan implant. All these patients were clinically evaluated at follow-up using the DASH score, Mayo Wrist score and VAS pain score.
