Treatment modalities included internal fixation (80%; 76% of displaced fractures), hemiarthroplasty (17%) and total hip replacement (3%). Follow-up was for a mean 3.67 years (range 0.01–5.96 years). Three patients died (3.4%). Of the displaced fractures treated with fixation, five patients developed avascular necrosis (8.9%); two of these were managed conservatively. Seven patients (12.5%) required a total of nine revision procedures. No failures occurred in other initial treatment modalities or undisplaced fractures. There was no significant relationship between pre-operative duration and subsequent avascular necrosis or need for revision surgery.
There was a significant difference between groups in interval between injury and surgery, with alcohol-abusers undergoing surgery 40.2 hours after injury compared to 22.2 hours for controls (p=0.039). Post-operative stay was also significantly different, with discharge at 7.0 and 5.0 days post-operatively for abusers and controls respectively (p=0.002). 26% of abusers required increased level of care after discharge compared with 15% of non-abusers, although this did not reach statistical significance. Reduction and fixation was employed in 26 alcohol-abusing patients and 30 controls. Early postoperative complications were similar in both groups with the exception of delirium tremens (17% of abusers). Of patients treated with internal fixation, four patients in the alcohol-abuse group required revision surgery (15%) compared to three of the control group (10%, no significant difference). Two patients within the abusers group developed avascular necrosis (7.7%) compared to three within the control population (10%, no significant difference); only two of these five required revision surgery with femoral head replacement. During the follow-up period, alcohol-abusers had a five-fold higher rate of subsequent fractures of their contralateral hip or elsewhere (p=0.02).
