The purpose of this study was to evaluate pubic ramus fracture fixation. This biomechanical evaluation compared standard plating techniques with retrograde medullary screw fixation of a superior pubic ramus fracture in a pelvic fracture model. ⋯ The posterior disruptions of the pelvic ring were not fixed. The APC-II injury created in this study resulted in significant (p < 0.05) motion at the disrupted rami and the injured SI joint, compared with the intact pelvic specimen.(ABSTRACT TRUNCATED AT 250 WORDS)

Between January 1989 and September 1991, 117 consecutive open tibial shaft fractures were treated at our institution. Of these, 64 (55%) met the inclusion criteria and were prospectively treated according to protocol using unreamed interlocking intramedullary nails as definitive fixation. Wounds were classified according to the method of Gustilo et al., and included 10 type I, 16 type II, and 38 type III (17 type IIIA, 21 type IIIB) wounds. ⋯ Mean time to healing was as follows: type I, 4.8 months; type II, 4.7 months; type IIIA, 8.28 months; and type IIIB, 9.30 months. Twenty fractures exhibited a delay in healing (> 6 months). This included two of 12 type II (16%), six of 10 type IIIA (60%), and 12 of 15 type IIIB fractures (80%).(ABSTRACT TRUNCATED AT 250 WORDS)
