68. What other approaches (` posterolateral) can be used in resurfacing ?

1) Anterior approach (Watson-Jones) (Smith-Peterson) 2) Anterolateral approach 3) Ganz-approach (anterior dislocation, after anterior capsulotomy and greater trochanter osteotomy) All 3 approaches keep the vascularisation of the femoral head intact (circumflex vessels). The anterolateral approach has the disadvantage of abductor muscle destruction with possible persistent gaitproblems. The Watson-Jones and Ganzapproach do not have this problem where the big disadvantage in the Ganzapproach is the greater trochanter osteotomy. 1) Possible risk on not healing of the osteotomy (pseudarthrosis) 2) 6 weeks partial weight bearing with 2 crutches are necessary (only 10 kg!) 3) A second procedure for removal of the screws is necessary
