To characterise injuries sustained in basketball and netball that result in hospital admission and to compare the profiles of injury between the two sports.

Population-based retrospective descriptive epidemiological study using data from the National Hospital Morbidity Database, July 2000 to June 2004.

Patients discharged from a public or private hospital with basketball or netball codes as the “activity when injured”.

There were 5090 basketball-related hospital admissions (mean patient age, 22.2 [SD, 10.7] years; 71.5% male) and 4596 netball-related admissions (mean patient age, 26.3 [SD, 10.9] years; 88.9% female). Fractures were the most common injury (46.8% [2384] of basketball-related and 29.5% [1358] of netball-related admissions), with the forearm and hand or wrist the most common fracture sites. The participant-based forearm fracture hospitalisation rate (5 + years age group) peaked in the 5–14-years age group. Anterior cruciate ligament rupture was the most common diagnosis, accounting for 760 (16.5%) netball-related admissions (mean [SD] age, 26.7 [8.4] years) and 354 (7.0%) basketball-related admissions (mean age, 25.5 [7.9] years). Achilles tendon injury accounted for 732 (15.9%) netball-related admissions (mean age, 35.2 [7.5] years) and 381 (7.5%) basketball-related admissions (mean age, 35.8 [7.8] years).

The high rates of anterior cruciate ligament rupture and Achilles tendon injury resulting in hospital admission and their long-term consequences impact extensively on the individual and the community. The common injuries sustained in basketball and netball were strongly age-related.
