To compare the complications and functional and radiographic outcomes of volar and dorsal plating of intra-articular distal radius fractures. ⋯ Therapeutic, Level III.

In contrast to isolated diaphyseal fractures of the ulna (so-called night-stick fractures), isolated fractures of the radial diaphysis generally are expected to have associated injury of the distal radioulnar joint (DRUJ), the so-called Galeazzi fracture. This study retrospectively reviewed isolated fractures of the radial diaphysis in a large cohort of patients to determine how often such fractures occur without DRUJ injury ⋯ Therapeutic, Level IV.

Recently the length of core suture purchase has been identified as a variable affecting the strength of tendon repairs. The influence of the length of the core suture purchase on the strength of multistrand locking and grasping suture repairs, however, has not been studied extensively in transversely lacerated tendons. We assessed the effects of the length of the core suture purchase on the strength of three 4-strand grasping or locking repair techniques. ⋯ The length of core suture purchase significantly affects the strength of these 4-strand tendon repairs. The forces required for gap formation and the ultimate failure of repairs with 0.4-cm purchase were 20% to 45% lower than those of the repairs with 1.0-cm purchase. Locking repairs did not show a greater capacity to offset the decrease in strength than grasping repairs when the length of core suture purchase was decreased from 1.0 to 0.4 cm. Our study indicates that the length of suture purchase directly influences the strength of both locking and grasping core tendon repair methods.

Radial collateral ligament (RCL) injuries of the thumb metacarpophalangeal (MCP) joint are much less common than ulnar collateral ligament injuries. Cast or splint immobilization is recommended for treating grade I and grade II tears; however, there is no consensus for treating grade III (complete) tears of the RCL. The purpose of this study was to assess the results of repair of acute grade III tears of the RCL and evaluate the efficacy of late reconstruction for chronic instability. ⋯ Therapeutic, Level IV.

Because our experience with the techniques used in denervation surgery of the wrist joint often has proven insufficient in treating chronic pain we conducted an anatomic study to clarify the exact contributions of the nerves supplying the wrist joint. Our goal was to reveal all periosteal and capsular nerve connections and if necessary adjust our technique used in denervation surgery. ⋯ Based on our findings we propose to denervate the wrist by making 2 incisions. With one palmar and one dorsal incision it should be possible to disconnect the periosteum from the capsule and interrupt the majority of the capsular nerve branches.
