ABSTRACT
Objective To study the short-and long-term effects of SuperPath minimally invasive arthroplasty for the treatment of femoral head necrosis.Methods The subjects were 50 patients with femoral head necrosis.Randomly divided into the control group and observation group with 25 cases in each group.The patients in the control group were treated with total hip replacement through anterolateral small incision.The patients in the observation group were treated with minimally invasive total hip replacement through SuperPath incision.Compared two groups of the perioperative indexes and the incidence of complications, and all patients were followed up for 6 months, compared before and after operation of the Harris hip function score and visual analogue method were evaluated.Results The observation group of the drainage flow[ (211.83±23.76) ml], intraoperative blood loss[ (354.06±38.28) ml], hospitalization time[ (8.74±1.53) d], the difference of leg length[ (12.97±3.05) mm] and thigh circumference[ (5.41±0.58) mm] was significantly lower than the control group[ (150.49±18.61) ml, (213.95±30.24) ml, (4.52±1.06) d, (8.12±2.30) mm and (2.87±0.51) mm, respectively] (P＜0.05).1 year after operation, the Harris score (89.30±4.19) and Barthel index (90.63±4.95) in the observation group were significantly higher than the control group (81.86±5.24, 79.47±5.36) (P＜0.05).VAS score was significantly lower in observation group (0.85±0.43) than that in control group (2.09±0.61) (P＜0.05).The incidence of complications in the two groups was not significantly different (P＞0.05).Conclusion SuperPath incision minimally invasive total hip arthroplasty for the treatment of avascular necrosis of the femoral head has advantages such as small trauma, low complication and significant effect.It can relieve pain and promote hip joint function and quality of life recovery.
ABSTRACT
Objective:To compare various data of open pyeloplasty,laparoscopic pyeloplasty and en-dopyelotomy as a treatment of ureteropelvic junction obstruction(UPJO),and to investigate and discuss the feasibility and effect of the three methods.Methods:In the study,109 cases of UPJO treated by dif-ferent surgical approaches in Peking University People’s Hospital from January 2004 to December 2014 were retrospectively investigated.The patients were divided into three groups according to the treatment they received:open peyloplasty group (32 cases),laparoscopic peyloplasty group (31 cases)and en-dopyelotomy group (46 cases).We compared the data of the operative time,intraoperative blood loss, perioperative complications and post-operative hospital stay among the three groups.The mean follow-up time was(51.9 ±40.1 )months (6 -132 months).Results:None of the laparoscopic peyloplties was converted to open peyloplasty.All endpyelotomies were successfully completed.The operative time was as follows:laparoscopic peyloplasty group (195.97 ±55.22)min,open peyloplasty group (121.19 ± 33.95)min and endopyelotomy group (74.04 ±33.95 )min,and there were significant differences among the three groups respectively(P 0.05).Conclusion:The laparoscopic peyloplasty group had a longer operative time than open peyloplasty group,while its post-operative stay was shorter. There was no significant difference on the operative blood loss between open peyloplasty group and laparo-scopic peyloplasty group.Although the success rate of endopyelotomy was lower than those of the other two groups,it had advantages over the aspect of operative time,operative blood loss and post operative stay.
