Many surgical procedures have been described for treating painful osteoarthritis at the carpometacarpal joint of the thumb. This article reports our clinical and radiographic results in performing suspensionplasty using the abductor pollicis longus (APL) tendon without tendon interposition after a complete trapeziectomy for patients with painful osteoarthritis in the carpometacarpal joint of the thumb. ⋯ Therapeutic, Level IV.

With their intrinsic vascularity vascularized bone grafts provide an alternative solution to the challenging problem of scaphoid nonunions. The union rate (after imaging evaluation including magnetic resonance imaging [MRI]) and functional outcome of using vascularized bone grafts pedicled on the palmar carpal epiphyseal artery for waist nonunions of the scaphoid are reported in this prospective case series. ⋯ Therapeutic, Level IV.

Comparative Study
Biomechanical stability of a fixed-angle volar plate versus fragment-specific fixation system: cyclic testing in a C2-type distal radius cadaver fracture model.
To compare the biomechanical stability of 2 recently introduced fixation systems in an intra-articular, dorsal comminution distal radius fracture model. ⋯ Both fixed-angle volar plate and fragment-specific fixation systems performed comparably in a simulated early postoperative motion protocol. Fragment-specific fixation had improved stiffness characteristics only with respect to the smaller ulnar-sided fragment.

For chronic dynamic scapholunate (SL) instability (>3 months after injury) open procedures (capsulodesis, limited intercarpal fusions, tenodesis, SL ligament reconstruction) have become popular in recent years but their long-term results have been suboptimal. We evaluated retrospectively the results of aggressive arthroscopic debridement of the SL ligament to bleeding bone in an effort to induce scar formation and closed pinning of the SL joint in patients unwilling to have an open procedure. ⋯ Therapeutic, Level IV.
