JBJS september
Background: Plate osteosynthesis is the most commonly used technique for the treatment of diaphyseal forearm fractures in adults. However, application of a plate can disrupt the periosteal blood supply and necessitates skin incisions that may be unsightly, and there is a risk of refracture if the implant is removed. The purpose of this study was to assess the early results of the use of a contoured interlocking intramedullary nail to stabilize displaced diaphyseal fractures of the forearm.
Methods: Between January 2004 and July 2006, a total of thirty-eight interlocking intramedullary nails were inserted into the forearms of twenty-seven adults. Eighteen nails were used in the radius and twenty were used in the ulna to stabilize a diaphyseal fracture. The mean follow-up period was seventeen months. Functional outcomes were assessed with use of the Grace and Eversmann rating system, and patient-rated outcomes were assessed by completion of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire.
Results: The average time to fracture union was fourteen weeks. There was one nonunion of an open comminuted fracture of the middle third of the ulna. There were no deep infections or radioulnar synostoses. According to the Grace and Eversmann rating system, twenty-two patients (81%) had an excellent result; three (11%), a good result; and two (7%), an acceptable result. The DASH scores averaged 15 points (range, 5 to 61 points).
Conclusions: Our experience indicates that the advantages of an interlocking intramedullary nail system for the radius and ulna are that it is technically straightforward, it allows a high rate of osseous consolidation, and it requires less surgical exposure and operative time than does plate osteosynthesis. We suggest that the interlocking intramedullary nail system be considered as an alternative to plate osteosynthesis for selected diaphyseal fractures of the forearm in adults.
Outcome After Surgery for the Treatment of Hip Fracture in the Extremely Elderly
JBJS september
Background: As a consequence of changes in population demographics, the extremely elderly represent one of the fastest growing groups in Western society. Previous studies have associated advanced age with increased mortality after hip fracture; however, this finding has not been consistent.
Methods: The Scottish Hip Fracture Audit is a prospective, national, multicenter study that collects data on patients over the age of fifty years who are admitted to the hospital with a hip fracture. For the present study, we used data collected from twenty-two acute-care orthopaedic units between January 1998 and December 2005. The extremely elderly cohort consisted of 919 individuals with an age of ninety-five years or more. Case-mix variables and outcomes were compared with those for a modal control group of 15,461 individuals who were seventy-five to eighty-nine years of age. Outcome measures included thirty and 120-day mortality rates, the length of the hospital stay, the place of residence, and mobility. A multivariable logistic regression model was used to compare outcomes between groups while controlling for significant case-mix variables.
Results: The extremely elderly presented with poorer indicators of health status as demonstrated by higher American Society of Anesthesiologists scores. In addition, this group was less likely to be independently mobile and more likely to be in institutional care at the time of the fracture (p < 0.001). Mortality at thirty and 120 days was higher in the extremely elderly even after adjusting for case-mix variables. The extremely elderly also were less likely to return home or to return to previous levels of mobility.
Conclusions: Although the extremely elderly exhibited a higher prevalence of prefracture indicators of poor outcome, statistical control for these case-mix variables showed further age-related deterioration in survival and outcomes after surgery for the treatment of a hip fracture.

背景 钢板接骨术对于治疗成人前臂骨干骨折来说，是最常用的技术。然而钢板的使用可能扰乱骨膜血供，皮肤切口也是不雅观的，如果植入物取出后，也存在再次骨折的风险。本研究的目的是评估交锁髓内钉用于稳定移位的前臂骨干骨折的早期结果。
