Open Surgery for Trigger Finger Required Combined a1-a2 Pulley Release. A Retrospective Study on 1305 Case.

Objectives: We retrospectively reviewed 1305 open-surgery for idiopathic trigger finger performed by 4 senior hand surgeons between 2014 and 2016.

Material And Methods: Medical records and a telephone interview made with a minimum follow-up of 1 year were used to identify the recurrent rate of triggering and other complications.

Results: This retrospective study let us note that 169 fingers (13%) required simultaneous release of the A1-A2 pulleys because the sectioning of the A1 pulley alone did not lead to complete free sliding of the tendons.

Antegrade Percutaneous Intramedullary Fixation Technique for Metacarpal Fractures: Prospective Study on 150 Cases.

Objectives: The aim of our study was to assess the results of antegrade percutaneous intramedullary Kirschner wire (K-wire) fixation, for the treatment of unstable displaced metacarpal fractures in a large number of cases, in order to support the usage of this mini-invasive technique in the largest variety of fractures as possible.

Material And Methods: Every patient meeting the inclusion criteria was treated with closed reduction and antegrade intramedullary fixation with 1 or 2 K-wire from January 2013. A total of 150 patients with 165 metacarpal fractures were evaluated until February 2016.

Debris of carbon-fibers originated from a CFRP (pEEK) wrist-plate triggered a destruent synovitis in human.

Application of carbon-fiber-reinforced-polymer (CFRP) artifacts in humans has been promoted in Orthopedic and Trauma Surgery. Literature documents the biocompatibility of materials used, namely carbon fibers (CF) and poly-ether thermoplastics, like poly-ether-ether-ketone (PEEK). A properly designed and accurately implanted composite artifact should not expose its fibers during or after surgery: however this may happen.

A more detailed mechanism to explain the "bands of Fontana" in peripheral nerves.

Introduction: In 1779, Fontana identified transverse and oblique bands along peripheral nerves. Subsequent studies pointed alternatively to endoneural or perineural components as the cause. Our aim was to clarify these conflicting findings.

Combining an external fixator and an artificial nerve-guide for the treatment of a complex digital injury.

A complex digital injury, with tendon, nerve and bone losses, may pose the problem of which structure deserves the highest priority. Authors were able to treat tendon, nerve and bone lesions with the same level of priority thanks to the combined use of an external fixator and a nerve-guide.
