Perilunate Fracture-Dislocation: Results at Mean Follow-Up of 7 Years after ORIF.

Perilunate fracture-dislocations are frequently associated with a high risk of developing post-traumatic arthritis. Current studies indicate that during mid-term follow-ups, radiological signs of arthritis do not appear to correspond with functional score. The aim of this study was to assess the occurrence of posttraumatic arthritis and the wrist function after perilunate dislocations (PLD) and fracture dislocations at a mid-term follow-up of 7 years.

Comparison between scaphotrapeziotrapezoid arthrodesis and Pyrocardan® implant for isolated scaphotrapeziotrapezoid osteoarthritis.

Introduction: Scaphotrapeziotrapezoid (STT) arthrodesis and Pyrocardan® implant for painful isolated STT osteoarthritis have shown good results, but no paper has compared their medium-term outcomes.

Hypotheses: Our main hypothesis would be that the Pyrocardan® implant, by preserving the carpal biomechanics, could lead to better wrist mobility. Our secondary hypotheses would be that no other clinical and radiological differences will be found between these two procedures at a mean 5 years follow-up.

Intercarpal arthrodesis: A systematic review.

Intercarpal arthrodesis is a well-established option to treat various disorders of the carpus, such as localized osteoarthritis, carpal instability, and Kienböck's disease. This is a non-conservative procedure aimed at obtaining a stable and congruent interface between the radius and the proximal carpal row, which restores wrist function by minimizing pain and restoring grip strength. These procedures generally yield good predictable results that are maintained over time.

Pyrocardan Scaphotrapeziotrapezoid Joint Arthroplasty for Isolated Osteoarthritis: Results after a Mean Follow-Up of 5 Years.

 Isolated scaphotrapeziotrapezoid (STT) osteoarthritis (OA) mainly develops in women over 50 years of age in a bilateral manner. Many surgical treatments are available, including distal scaphoid resection with or without interposition, trapeziectomy, and STT arthrodesis. However, there is a controversy about which procedure is the most effective.

Proximal interphalangeal joint arthroplasty with the Tactys® prosthesis: Clinical and radiological outcomes at a mean 3.1 years' follow-up.

Preliminary results with the Tactys® modular gliding prosthesis for proximal interphalangeal joint (PIPJ) replacement were encouraging, with notable improvement in clinical and functional scores at 1 and 2 years' follow-up. However, a recent study found a trend for deterioration over time. We wanted to check this by analyzing medium-term outcomes.
