Background
Early stage osteonecrosis of the femoral head (ONFH) has many treatment options including core decompression with implantation of a tantalum rod. The purpose of this study was to evaluate clinical and radiological outcomes and potential complications during conversion total hip arthroplasty (THA) in such patients.Methods
Six male patients (8 hips) underwent THA subsequent to removing a tantalum rod (group I) from April 2010 to November 2011. We retrospectively reviewed the medical records of these patients. We enrolled 12 age- and sex-matched patients (16 hips) during the same period, who had undergone primary THA without a previous operation as the control group (group II). All patients were followed for at least 3 years. We checked the Harris hip score (HHS), operative time, and volume of blood loss. Radiological results, including inclination, anteversion of the acetabular cup, presence of periprosthetic osteolysis, and subsidence of femoral stem were checked at the last follow-up.Results
The mean preoperative HHS values were 56.5 (range, 50 to 62) and 59.1 (range, 42 to 70) in groups I and II, respectively. The HHS improved to 96.0 (range, 93 to 100) and 97.6 (range, 93 to 100), respectively, at the 3-year follow-up (p = 0.172). Mean operation time was 98.8 minutes (range, 70 to 120 minutes) in group I and 77.5 minutes (range, 60 to 115 minutes) in group II (p = 0.006). Total blood loss volumes were 1,193.8 mL (range, 960 to 1,360 mL) and 944.1 mL (range, 640 to 1,280 mL) in groups I and II, respectively (p = 0.004). No significant differences in inclination or anteversion of acetabular cup and no evidence of osteolysis or subsidence of the femoral stem were reported in either group in radiological follow-up results. However, one case of squeaking occurred in group I during the follow-up.Conclusions
The two groups showed no clinical or radiological differences except extended operative time and increased blood loss. However, the incidence of squeaking (1 of 8 hips) was higher, as compared to the control group or previously reported values. 相似文献2.

This study compared the pain score, cosmetic outcome and wound complication rate between zip‐type skin‐closing device and conventional staple device. Forty‐five subjects with zip‐type skin‐closing device (the zip group) and 45 subjects with the conventional staple device (the staple group) after total knee arthroplasty were compared. Visual analogue scale score was significantly higher on postoperative (PO) 1, 3, 14 day (D) in the staple group compared to the zip group (P < 0·05). The Vancouver scar score was significantly better in the zip group compared to that of the staple group (4·6 ± 0·7 versus 6·9 ± 1·3, P = 0·043) on PO 90D. There was no significant wound complication rate between the two groups. The zip‐type skin‐closing device showed less pain PO 14D, especially during dressing and removal of the device, and better cosmetic outcome 3 months after surgeries. Surgeons may consider using the zip‐type skin‐closing device for patients who want less pain and better cosmetic outcome. 相似文献
