The aim of this study was to determine the comorbid risk factors for failure in young patients who undergo fixation of a displaced fracture of the femoral neck. We identified from a prospective database all such patients ≤ 60 years of age treated with reduction and internal fixation. The main outcome measures were union, failure of fixation, nonunion and the development of avascular necrosis.

There were 122 patients in the study. Union occurred in 83 patients (68%) at a mean follow-up of 58 months (18 to 155). Complications occurred in 39 patients (32%) at a mean of 11 months (0.5 to 39). The rate of nonunion was 7.4% (n = 9) and of avascular necrosis was 11.5% (n = 14). Failures were more common in patients over 40 years of age (p = 0.03). Univariate analysis identified that delay in time to fixation (> 24 hours), alcohol excess and pre-existing renal, liver or respiratory disease were all predictive of failure (all p < 0.05). Of these, alcohol excess, renal disease and respiratory disease were most predictive of failure on multivariate analysis.

Younger patients with fractures of the femoral neck should be carefully evaluated for comorbidities that increase the risk of failure after reduction and fixation. In patients with a history of alcohol abuse, renal or respiratory disease, arthroplasty should be considered as an alternative treatment.

We reviewed 27 diabetic patients who sustained a tibial fracture treated with a reamed intramedullary nail and compared them with a control group who did not have diabetes. There were 23 closed fractures and four were open. Union was delayed until after six months in 12 of the 23 (52%) diabetic patients with closed fractures and ten of the 23 (43%) control patients (p = 0.768). In two patients with diabetes (9%), closed tibial fractures failed to unite and required exchange nailing, whereas all closed fractures in the control group healed without further surgery (p = 0.489). In both the diabetic and control groups with closed fractures two patients (9%) developed superficial infections. There were two (9%) deep infections in diabetic patients with closed fractures, but none in the control group (p = 0.489).

Overall, there was no significant difference in the rate of complications between the diabetic patients and the control group, but there was a tendency for more severe infections in patients with diabetes.
