Comparative Study
Interfragmentary compression across a simulated scaphoid fracture--analysis of 3 screws.
To measure the interfragmentary compression generated across a simulated fracture in cadaveric scaphoids by 3 different headless compression screws. ⋯ The interfragmentary compression generated by the Acutrak Standard screw was significantly greater and more consistent than that generated by either the Bold or Acutrak Mini screws. The compression generated by the Acutrak Standard and Mini screws was significantly better sustained over time than that generated by the Bold screw; however, these differences were small and may not be clinically important. The optimal compression required to promote scaphoid fracture union remains unknown and clinical trials are needed to further evaluate the outcome from using these devices.

Closing wedge osteotomies are an attractive treatment option for distal radius malunion in patients with osteopenia; however, they require an ulnar head resection to accommodate closure of corrective osteotomy and to address the issue of ulnocarpal abutment. The literature contains little information on concomitant ulnar shortening osteotomy despite a physiologic solution. We report the functional and radiographic outcomes of 5 patients treated for symptomatic distal radius malunion with simultaneous radial closing wedge and ulnar shortening osteotomies. ⋯ This study showed that closing wedge osteotomy of the radius concomitant with ulnar shortening osteotomy is technically and functionally adequate. Our procedure is indicated for patients with osteopenia for whom opening wedge osteotomy of the radius is inadequate.
