Trapeziectomy With Ligament Reconstruction and Tendon Interposition Versus a Trapeziometacarpal Prosthesis for the Treatment of Thumb Basal Joint Osteoarthritis.

Numerous surgical procedures have been described to treat trapeziometacarpal osteoarthritis, but no approach is currently considered superior. Good long-term outcomes have been reported with multiple procedures. No studies have been published comparing outcomes of the Arpe joint replacement (Biomet, Valence, France) with those of ligament reconstruction and tendon interposition (LRTI) using the Burton-Pellegrini technique.

Ghrelin and adipose-derived mesenchymal stromal cells improve nerve regeneration in a rat model of epsilon-caprolactone conduit reconstruction.

Objective: Attempts have been made to improve nerve conduits in peripheral nerve reconstruction. We investigated the potential therapeutic effect of adipose-derived mesenchymal cells (ASCs) and ghrelin (GHR), a neuropeptide with neuroprotective, trophic, and developmental regulatory actions, on peripheral nerve regeneration in a model of severe nerve injury repaired with nerve conduits.

Material And Methods: The right sciatic nerves of 24 male Wistar rats were 10-mm transected unilaterally and repaired with Dl-lactic-ε-caprolactone conduits.

Comparison of Outcomes of Intertrochanteric Fracture Fixation Using Percutaneous Compression Plate Between Stable and Unstable Fractures in the Elderly.

Objectives: To evaluate the outcomes of treatment with a percutaneous compression plate (PCCP) in stable and unstable intertrochanteric hip fractures.

Design: Clinical prospective nonrandomized cohort study.

Setting: San Cecilio University Hospital, Granada (Spain).

Sauvé-Kapandji and reverse Sauvé-Kapandji procedures for treating chronic longitudinal radioulnar dissociation with capitellum fracture.

Almost all reported cases of longitudinal radioulnar dissociation have involved fracture of the radial head, rupture of the interosseous membrane, and disruption of the distal radioulnar joint, although unusual patterns of Essex-Lopresti injury have also been described. To our knowledge, this is the first report of a chronic Essex-Lopresti variant including fracture of the capitellum. A displaced capitellum fracture must alert to the possibility of longitudinal radioulnar dissociation, even without concomitant radial head fracture or symptoms at the forearm and ulnar wrist.

An ex vivo model in human femoral heads for histopathological study and resonance frequency analysis of dental implant primary stability.

Objective: This study was designed to explore relationships of resonance frequency analysis (RFA)-assessed implant stability (ISQ values) with bone morphometric parameters and bone quality in an ex vivo model of dental implants placed in human femoral heads and to evaluate the usefulness of this model for dental implant studies.

Material And Methods: This ex vivo study included femoral heads from 17 patients undergoing surgery for femoral neck fracture due to osteoporosis (OP) (n = 7) or for total prosthesis joint replacement due to severe hip osteoarthrosis (OA) (n = 10). Sixty 4.

Rupture of extensor tendon secondary to previously undiagnosed Kienböck disease.

We report three patients with an unusual pattern of rupture of the extensor tendon. All were found to have previously undiagnosed Kienböck disease. Radiographic study of the wrist is essential before treating any closed rupture of an extensor tendon.
