A retrospective study of AO type 42 tibial diaphyseal fractures that presented to a teaching hospital over a 54 month period was made to identify the proportion sustained whilst playing soccer, determine their characteristics and report treatment and outcome. Sport accounts for 73/329 (22.1%) of these fractures and soccer 58/73 (79. 5%) of these. All patients were male with mean age of 24.3 years (range 8-48). Fifty-four fractures were closed and 93.1% (54/58) were situated in the middle third or at the junction of the middle and distal thirds of the diaphysis. Fifty-six (96.6%) had simple or wedge patterns and 45 (77.6%) were right sided. Forty-four (76.2%) were treated non-operatively in plaster, 12 (20.3%) by intramedullary nails and two (3.4%) with external fixators. Two patients were lost to follow-up and the remaining 56 fractures united at a mean of 6.5 months. There were 21 complications in 19/56 (33.9%) patients which included 8/56 (14.3%) delayed/non-unions requiring surgery. There was a significantly higher complication rate for operated fractures (p<0.005) but no significant link to AO fracture type. Thus we cannot assume that treatment of these common fractures is without risk, especially if they are treated operatively.
