Anatomic And Clinical Significance Of The Anterolateral Hip Joint Capsule And Iliofemoral Ligament

Objective:To investigate anatomic features of the anterolateral hip joint capsule and the iliofemoral ligaments for clinical practice.Methods:30 adult cadaver hips fixed with formalin were used for this study. Dissecting into the anterolateral hip joint capsule and the iliofemoral ligaments, the anterolateral hip joint capsules were divided into 3 sectors and 9 parts.The average thickness of each part was measured. The average hight and wide of each sector was measured.The anterolateral hip joint capsules were observed of their origin, insertion, course, branch and histological sections.Results:The iliofemoral ligaments concrescented tightly together with capsule. They formed a complex. The thickness of the capsule was ununiformity. The thinnest part of the complex are B â… ,B â…¡ and Câ…¡. In addition, The average high and wide of each sector was ununiformity. From its origin on the anterior inferior iliac spine and acetabulum, and divided into three branches.Finally it fixed on intertrochanteric line.Conclusions:Understanding of the the anterolateral hip joint capsule and the iliofemoral ligaments may make for the design and the optimization of the operation.Objective:To compare the safety and practical value of with or without reserving the capsule in anterolateral approach total hip arthroplasty(THA).Methods:Since January 2014,39 cases were recruited in the retrospective study within the patients with hip joint disease undergoing THA via anterolateral approach in one year. According to reserving the capule or not, the cases were classified into 2 group, Group A (31 cases reserving articular capsule) and Group B (8 cases not reserving articular capsule).There were no significant difference between the two groups in gender, age and preoperative hemoglobin (P>0.05). Make comparison in the following aspects between groups.including the Harris hip score and Visual Analogue Score in preoperation and postoperation (in 2 weeks, 6 months and 9 months), the volume of drainage in the first day postoperative and the blood transfusion rate of post-operation.Results:All patients were followed up for 9 to 10months postoperatively,9.5months on average and all incisions healing well.There were no significant differences between two groups in operation time, Harris hip score and Visual Analogue Score (in 6 and 9 months after operation)(P>0.05).The groups displayed statistical differences compared with the drainage volume in the first postoperative day,the blood transfusion rate of postoperation and Harris hip score and Visual Analogue Score (in 14 postoperative days)(P<0.05).Conclusions:There was no effect can be proved in reserving capsule or not during THA on changing the several valuation indicators, i.e. operative time,the Harris hip score and Visual Analogue Score in 6 and 9 months after operation. Reserving the capsule provided curative effect in short-term on reducing the rate of post-operative hemorrhage and blood transfusion.
