Outcomes were assessed clinically and radiographically at a period averaged 11.5(range from 4 to 20) years.RESULTS Minor trauma caused dislocation in seven and severe trauma in ten patients. All dislocations were posterior, six isolated dislocation and 11 were associated with other injuries. The negligence period averaged 2.5(ranged from 1 to 4) d. At the latest visit, the radiography revealed normal hip in 11 and avascular necrosis(AVN) in six patients. Clinically, eight patients were rated as excellent, three good, three fair and three poor.CONCLUSION We believe the factors that contribute to increased intracapsular pressure also increase the influence of delayed reduction toward the development of AVN.展开更多

The objective of this study was to compare the effectiveness of coblation intracapsular tonsillectomy (ICT) and coblation complete tonsillectomy (CT) as treatments for OSA. Study design: A retrospective study of all the children ages 2 - 18 years with OSA who underwent coblation intracapsular tonsillectomy (ICT) or coblation complete tonsillectomy (CT) from January 2007 to August 2010 by the same surgeons at one institution. Methods: Data were retrieved from children’s charts and from telephone interviews with children’s parents, regarding pre and postoperative OSA-18 scores, postoperative pain, postoperative complications, use of analgesic drugs, and time to return to a solid food diet. Results: All 43 children who underwent ICT and 37 children who underwent CT suffered from OSA before surgery, and none did postoperatively. There were no minor complications in the ICT group, compared to 13.5% in the CT group (p = 0.01). According to parental report, 72% and 21% suffered a low level of postoperative pain, and 9% and 33% severe pain in the ICT and CT groups, respectively. For these respective groups, 49% and 73% needed analgesic drugs (p < 0.05);and 65% and 35% ate solid food during the first 3 days post surgery. Conclusions: Both ICT and CT were safe, with few complications;however recovery was faster in the ICT group, as demonstrated by less pain, and more rapid return to a solid food diet.展开更多

Malunion of these fractures have been described in the coronal plane （coxa valga or coxa rata）. We reported a case of young adult patient with displaced intracapsular fracture of femoral neck that had malunited in sagittal plane with callus formation with excellent functional outcome. The radiographs revealed intracapsular fracture of femoral neck right side （Garden type 4 and Pauwel type 3）. The patient was operated and closed reduction and internal fixation with three cannulated cancellous screws was performed. The postoperative radiograph revealed a loss of reduction in the lateral view. Due to this technical error, the patient was counselled for revision fixation for which he refused. At 9 months we observed union of the fracture in the displaced position by callus formation. Harris hip score at 2 years was 96 that indicate excellent functional outcome and the ra- diographs did not reveal any evidence of avascular necrosis of femoral head. We advised revision surgery to our patient as he had increased chances of implant failure and nonunion. However he refused the revision surgery and was continued with the suboptimal reduction. However, the fracture united and that too with callus formation, which is not a described phenomenon in neck of femur fracture.展开更多
