Introduction: We investigated the incidence, risk factors and outcome of acute renal dysfunction (ARD) in patients with a fractured neck of femur.

Methods: 170 consecutive patients were prospectively included in the Scottish hip fracture audit database and retrospectively analysed. Historically, lack of consensus definition hindered accurate reporting of ARD. We defined ARD using the ‘RIFLE’ criteria recently described by the Acute Dialysis Quality Initiative (ADQI) Group.

Results: 27 patients (16%) developed ARD. Risk factors were male sex, vascular disease, hypertension, diabetes, chronic kidney disease and pre-morbid use of nephro-toxic medications (p< 0.01). Inpatient, 30 and 120 day mortality was higher in the ARD group 19%, 22% and 41% respectively, versus 0%, 4% and 13% in the non-ARD group (p< 0.01) Length of hospital stay was significantly longer in the ARD group; 20 days compared to 13 days for patients in the non-ARD group (p< 0.01). Pre and post-operative complications were 12 and 5 times more frequent respectively in the ARD group (p< 0.01).

Discussion: Acute renal dysfunction is an important adverse event in this population. Awareness of risk factors and serial measurements of renal function will enable early identification and focused monitoring of these patients.

To illustrate the incidence and epidemiology of fractures due to football.

All inpatient and outpatient fractures from a prospectively collected database for a defined population in 2000 were retrospectively analysed.

There were 396 football fractures, 96% male. Football caused 39% of the 1022 sports fractures in 2000. This represented 5% of the 8151 fractures in total. The incidence was 61/105. 115/105 in males and 5 /105 in females. The average age was 22.9 years; 22.8 in males and 26.6 in females. 77% of fractures were treated as outpatients. The top five fractures representing 84% of the injuries were Radius+Ulna 30%, Phalanx 19%, Tibial+Fibula 18%, Metacarpal 11% and Clavicle 5%. 71% were upper-limb fractures. The busiest two months were October and May 17% and 14% respectively. The quietest two months were February and December at 5%.

Although the epidemiology of football injuries will vary amongst different populations, these results can be generalized to similar population bases. Results will be valuable to medical professionals supporting football teams, enabling them to focus their attention on treating the most common injuries, the majority being treated as outpatients.

Football is the most common cause of fractures in sport. As participation increases, the incidence of fractures is likely to reflect this. Upper limb fractures account for over 2/3 rd of fractures with radius+ulna fractures accounting for up to a 1/3rd of fractures; the majority can be treated as an outpatient. Therefore medical teams should be familiar with standard treatment regimes, possible impact on players’ futures and time out of sport.
