Sterling Bunnell, MD, was the key person in the founding of the specialty of hand surgery in the United States. In 1944 he published Surgery of the Hand, which was to remain the authoritative hand text for almost 30 years. At about the same time he organized and was the guiding light of 9 United States Army Hand Centers spread throughout the United States. For the most part the surgeons who directed these hand centers became the founders of the American Society for Surgery of the Hand.

The purpose of this study is to report the results of intact radial collateral ligament (RCL) soft tissue sleeve advancement with bony reattachment without additional soft tissue reinforcement as the sole surgical repair technique for the treatment of grade III RCL injuries to the thumb metacarpophalangeal (MCP) joint in acute, chronic, and late cases. ⋯ Acute, chronic, and late grade III RCL instability of the thumb MCP joint can be successfully treated in the majority of cases by RCL soft tissue sleeve advancement and bony reattachment alone without the need for other soft tissue reinforcement.

Comparative Study
AO-wrist arthrodesis: with and without arthrodesis of the third carpometacarpal joint.
The incorporation of the third carpometacarpal joint (CMCJ-3) during wrist arthrodesis is controversial. This retrospective study of 146 consecutive wrist arthrodeses with AO plate fixation specifically addresses this question. In 79 wrist arthrodeses the CMCJ-3 was also arthrodesed, and in 67 the CMCJ-3 was simply bridged. ⋯ Eleven of these were painful and further surgical treatment was required. In contrast, of 34 wrists with the CMCJ-3 bridged all but one remained free of symptoms after the plate had been removed. We conclude that the CMCJ-3 must not be included in the arthrodesis when performing an AO-wrist arthrodesis.

Ulnar-sided injuries of the wrist have received more attention recently for their potential negative impact on the outcome of distal radius fractures. Radiographs and medical records were retrospectively reviewed for 166 distal radius fractures treated during a 1-year interval. Distal radius fractures were classified according to the AO system, and accompanying ulnar styloid fractures were evaluated for both size and displacement. ⋯ The distribution of ulnar styloid fractures was not random; greater than one third involved the base. All distal radius fractures complicated by distal radioulnar joint instability were accompanied by an ulnar styloid fracture. A fracture at the ulnar styloid's base and significant displacement of an ulnar styloid fracture were found to increase the risk of distal radioulnar joint instability.

The purpose of this study was to quantify the strain of the median nerve and the ulnar nerve throughout upper-extremity positioning sequences used by clinicians to evaluate nerve dysfunction. A microstrain gauge was used to quantify strain and digital calipers were used to assess nerve excursion in 4, fresh, intact cadavers. Data analysis of noncontinuous motion trials showed that the median nerve tension test caused a maximum summative strain in the median nerve at the carpal tunnel of 7.6%, with the largest increase in strain during elbow extension (3.5%). ⋯ The ulnar-nerve tension test caused a maximum summative strain in the ulnar nerve of 2.1%, with the largest increase in strain during shoulder abduction (0.9%). Some components of the ulnar-nerve tension test decreased strain in the median nerve. These cadaver findings lend support to the use of upper-extremity positioning sequences in the clinic to induce nerve strain during evaluation of nerve dysfunction.
