Objective To investigate the influencing factors of the hi p functional recovery after Pi pkin fracture surgery. Methods The cl inical data were retrospectively analysed, from 37 patients with Pi pkin fracture between May 2002 and February 2009. There were 32 males and 5 females, aged 26 to 98 years (median, 43 years). The causes of injury were traffic accident in 31 cases, a fall ing in 4 cases, and fall ing from height in 2 cases. The time from injury to operation was 1-28 days (mean, 8.6 days). According to the Pi pkin classification criteria, there were 23 cases of type II, 8 cases of type III, and 6 cases of type IV. Open reduction and internal fixation (ORIF) were performed in 27 cases, total hip arthroplasty (THA) in 10 cases.The relationships between gender, age, time from injury to surgery, type of fracture, treatment way and the hip functionalrecovery were analysed statistically. Results All patients achieved heal ing of incision by first intention, no infection anddeep venous thrombosis occurred. All patients were followed up 10 to 94 months with an average of 40.5 months. Bonefusion was observed at 5-11 months (mean, 8.9 months) in patients undergoing ORIF by X-ray examination; no prostheticloosening or subsidence occurred in patients undergoing THA. At last follow-up, Oxford Hip Score (OHS) was 16-58 points(mean, 37.2 points); the results were excellent in 12 cases, good in 13 cases, fair in 2 cases, and poor in 10 cases. The univarible analysis showed that the type of fracture and treatment way significantly affected the hip functional recovery (P lt; 0.05). The multivarible analysis showed that the type of fracture and treatment way had no significant effect on the hip functional recovery (P gt; 0.05). Conclusion Type and treatment way of Pi pkin fracture may affect postoperative hi p function recovery, so appropriate treatment should be selected based on fracture type to ensure the restoration of joint function.
