Primary trapeziectomy with Regjoint(TM), a poly-L/D-lactide spacer, a two-year follow-up study with new radiological assessment tool.

The aim of this retrospective study was to evaluate the potential bony erosion and the clinical and radiological results of primary trapeziectomy with RegjointTM interposition, in patients with peritrapezial arthritis. Data were recorded on twenty patients over a period of two years (January 2015-December 2016). On average 24 months, patients were reconvened for a post-operative evaluation (subjective evaluation of pain, function and patient satisfaction; clinical evaluation with strength and mobility measures; post-operative X-rays).

Surgical Fixation of Metacarpophalangeal Collateral Ligament Rupture of the Fingers.

Background: Collateral ligament injury of the metacarpophalangeal joint of the fingers is underreported in the literature and widely underestimated by the medical community. Here, the authors present results from a large series of patients and review factors influencing success of surgery.

Methods: The authors performed a retrospective study of 46 patients who underwent surgical fixation of the metacarpophalangeal collateral ligament using bone anchor in an acute or chronic setting.

[Retiform haemangioendothelioma: a case report].

Retiform haemangioendothelioma is a locally aggressive, very rarely metastasizing vascular lesion. Histologically, it is characterized by distinctive arborizing blood vessels resembling "rete testis" and lined by endothelial cells with characteristic hobnail morphology. We present an additional case, in the leg of a 64-year-old patient.

A severe complication of muscle transfer: clostridial myonecrosis.

We present a case of gas gangrene as a severe complication of muscle transfer for opponensplasty. After debridement, the extensive palmar wound was covered by a free gracilis muscle transfer. This complication of muscle transfer has to our knowledge never been reported previously.
