The vertical-centre-anterior margin (VCA) angle quantifies the anterior cover of the femoral head. However, when the femoral head is deformed it may be difficult to identify its centre. We have therefore created a new index, the anterior acetabular head index (AAHI) which is measured on the false-profile radiograph. We measured the VCA and AAHI angles in 312 hips in which the centre-edge angle was >25°. There were 250 patients, 86 men and 164 women, whose ages ranged from 20 to 65 years. The mean AAHI was 84.1% (81.7% in women and 88.5% in men). There was a correlation between the AAHI and VCA angles. Our data suggest that the AAHI is useful in the evaluation of anterior acetabular cover and that it is higher in men than in women.

Objective: To evaluate whether the serum β-enolase level is a useful indicator of exercise-induced muscle damage in athletes. Design: Blood samples were taken from 49 adult amateur marathon runners before and immediately after a marathon race, and the serum levels of β-enolase and creatine phosphokinase were measured. Setting: The Aoshima Taiheiyo Marathon 2000, Miyazaki, Japan, on a cloudy day in December with an ambient temperature of 18°C. Subjects: Forty-nine adult amateur marathon runners (42 men and 7 women) who regularly participated in runs. Intervention: The intervention was a marathon run. Main Outcome Measures: Serum β-enolase was measured using a sensitive sandwich enzyme-linked immunosorbent assay. Serum creatine phosphokinase was measured using a standard procedure. Results: The mean β-enolase concentration was 9.45 ± 3.11 ng/mL before the race. It increased to 22.11 ± 8.80 ng/mL after the race, representing a proportional increase of 1.57 ± 1.46. The serum concentration of β-enolase after the race was significantly higher than that before the race (P < 0.0001). Moreover, the serum β-enolase level increased as much as the creatine phosphokinase level after the race, and strongly correlated with creatine phosphokinase (r = 0.828, P < 0.0001). The proportional increase of β-enolase also correlated with that of creatine phosphokinase (r = 0.441, P < 0.005). Conclusions: Our data suggest that the absolute values of the serum β-enolase are more appropriate to relate to muscle damage.
