With increasing urban development in New Zealand, prehistoric Polynesian skeletal remains are frequently being recovered. Since such material must often be reinterred quickly, it has become important that the sex of individuals be determined from the remains in a relatively short time. For this purpose, discriminant function analysis was utilised for sex determination of prehistoric adult New Zealand Polynesian innominates (21 male and 35 female). Maximum diameter of the acetabulum was measured and subjected to SPSS direct discriminant function analysis. Accuracy of sex determination ranged from 85.2% to 86.2%. Reduction in error over random assignment by sex ranged from 70% to 72%. The two discriminant functions derived will provide a useful tool for the assessment of human remains in the forensic and archaeological context because they incorporate a single measurement which can be taken on incomplete bones.
OBJECTIVE: To determine if acetabular dysplasia increases the risk of incident hip osteoarthritis (OA) among elderly white women. METHODS: Baseline and followup anteroposterior pelvic radiographs were obtained a mean of 8 years apart, and read for individual radiographic features (IRFs) of hip OA; summary grades (0-4) were then assigned based on the IRFs present. Acetabular dysplasia was defined by the results of measurements of the acetabular depth (<9 mm) or the center-edge angle (<30 degrees). Logistic regression analyses were performed to determine the association between acetabular dysplasia and incident hip OA, and all analyses were adjusted for age, current weight, body mass index, affected side, and investigational site. RESULTS: The odds ratios for the association of abnormal center-edge angle and acetabular dysplasia with incident hip OA were 3.3 (95% confidence interval 1.1-10.1) and 2.8 (95% confidence interval 1.0-7.9), respectively. CONCLUSION: Acetabular dysplasia, defined by a decrease in the center-edge angle, is associated with a modestly increased risk of incident hip OA in elderly white women.
Fourty-nine patients with 50 complex acetabular fractures were treated with open reduction and internal fixation from August 1993 to February 1996 in a prospectively documented study. The fractures were fixed with small fragment implants through a modified extensile iliofemoral approach (Maryland approach). Thirty-seven patients were polytraumatized with an ISS of 20 pts. on average. In 10 patients the ISS was > 25 pts. Good or anatomic initial fracture reduction with a fragment stepoff K 2 mm could be achieved in 48 fracturers (96 %). Thirty-six patients with 37 fractures could be evaluated after 25 months on average. In 28 fractures (76 %) the functional outcome was good or excellent according to the d'Aubigne and Harris scores. Radiological results were excellent in 21 fractures (57 %) and satisfactory in 12 fractures (Heeg score). In 7 cases (14 %) a postoperative subcutaneous seroma had to be treated surgically. No wound infections, however, were observed. Further complications were secondary a loss of reduction in 4 cases (11 %), relevant heterotopic ossifications (Brooker III/IV) in 5 cases (14 %), and aseptic femoral head necrosis in 2 cases (5 %). In two cases a total hip replacement (THR) for posttraumatic arthritis had to be performed. Two more cases are scheduled for THR due to symptomatic femoral head necrosis. A good joint reconstruction can be achieved through the modified extensile iliofemoral approach (Maryland) in complex fractures of the acetabulum. However, the approach related morbidity seems to be worrisome. In complex fractures with comminution in the roof of the acetabulum the prognosis remains uncertain even in cases where initial anatomic joint reconstruction can be achieved.
