Sažetak
INTRODUCTION: Patients with high hip dysplasia (Crowe type III and IV) are more difficult to manage surgically, when compared to patients with Crowe type I and II dysplasia, due to much more pronounced anatomical irregularities of the bones that constitute the hip. The acetabulum is usually set much higher and also anteverted and shallow. Deficiency of bone mass at the superolateral acetabular ream may often be found. The femoral canal may be quite narrow, very deformed and there is usually big anteversion of the femoral neck. Functional results using standard surgical procedures for management of Crowe type III and IV patients are sometimes not optimal. A modification of the direct lateral approach was developed in our Department, which enables the surgeon an almost standard operating procedure even in the most difficult cases. OBJECTIVES: To present outcomes of total hip arthroplasty in patients with high hip dysplasia (Crowe type III and IV) using a modification of the lateral approach to the hip developed in our Department. METHODS: 28 patients with Crowe type III and type IV hip dysplasia were operated on using our modified approach. Clinical and functional analysis was performed preoperatively and 6 months after total hip arthroplasty (Muscle strength and range of motion as well as COOP WONCA, SF 36, Harris hip score, Oxford hip score, Womac hip score, Selfefficacy scale for falls, and stability testing with balance platform.) RESULTS: Results of all tests are provided and discussed (average preoperative vs. postoperative is given: HHS 52-89 pts, Womac 35.3-8.3, Oxford 30-17, SF36 Physical 37.3-49.9, SF36 Mental 44-53.8, Self efficacy scale 13-12, COOP WONCA 22-14). ROM and strength are recorded. CONCLUSION: Results suggest that even for patients with high hip dysplasia very good results after total hip arthroplasty could be achieved. Results are as good as in any THA for primary hip osteoarthritis. Additionally, technique is fairly simple to utilize and standard approach can be easily extended.
