The February 2013 Trauma Roundup³⁶⁰ looks at: the risk of ankle fractures; absorbable implants; minimally invasive heel fracture fixation; pertrochanteric fractures; arthroplasty and intracapsular hip fractures; and extensor mechanism disruption.

The October 2012 Trauma Roundup³⁶⁰ looks at: which patients die from pelvic ring fractures; monolateral distraction osteogenesis; surgical management of pelvic and peroneal blast injuries; weekend warriors at risk of going AWOL; early experience with the locking attachment plate; and fibula nailing - an alternate, and viable technique.

Many orthopaedic surgeons believe that obese patients have a higher rate of peri-operative complications and a worse functional outcome than non-obese patients. There is, however, inconsistency in the literature supporting this notion.

This study was performed to evaluate the effect of body mass index (BMI) on injury characteristics, the incidence of complications, and the functional outcome after the operative management of unstable ankle fractures.

We retrospectively reviewed 279 patients (99 obese (BMI ≥ 30) and 180 non-obese (BMI < 30) patients who underwent surgical fixation of an unstable fracture of the ankle. We found that obese patients had a higher number of medical co-morbidities, and more Orthopaedic Trauma Association type B and C fracture types than non-obese patients. At two years from the time of injury, however, the presence of obesity did not affect the incidence of complications, the time to fracture union or the level of function.

These findings suggest that obese patients should be treated in line with standard procedures, keeping in mind any known associated medical co-morbidities.
