Long-term follow-up of open reduction surgery for developmental dislocation of the hip.

Background: We posed 2 questions: what is the long-term result of open reduction surgery in developmental dysplasia of the hip, and is there an age at surgery above which the outcome was too poor to recommend the operation?

Methods: Between 1955 and 1995, 148 patients with 179 dislocated hips had open reduction surgery for developmental dysplasia of the hip (141 anterior and 38 Ludloff medial approaches). We attempted to locate all 148 patients for the follow-up evaluation.

Results: Fifty-three patients (36%) with 66 hips (37%) were located and participated in the study.

Measurement of the center edge angle and determination of the Severin classification using digital radiography, computer-assisted measurement tools, and a Severin algorithm: intraobserver and interobserver reliability revisited.

Background: Numerous studies underscore the poor intraobserver and interobserver reliability of both the center edge angle (CEA) and the Severin classification using plain film measurements. In this study, experienced observers applied a computer-assisted measurement program to determine the CEA in digital pelvic radiographs of adults who had been previously treated for dysplasia of the hip (DDH). Using a teaching aid/algorithm of the Severin classification, the observers then assigned a Severin rating to these hips.

Is research presented at the scoliosis research society annual meeting influenced by industry funding?

Study Design: All abstracts submitted to the 2006 SRS annual meeting were reviewed.

Objective: To determine the rate of funding in abstracts submitted for presentation at the 2006 Annual Scoliosis Research Society (SRS) meeting and whether funding produced bias toward a positive outcome.

Summary Of Background Data: Financial conflicts of interest have been attributed to bias in research.
