[The place of intertrochanteral valgus osteotomy (Pauwels II) in the surgical treatment of coxarthrosis. Biomechanical principles. Results. Apropos of a homogeneous series of 80 cases].
The authors report their experience of treating certain forms of coxarthrosis by valgus osteotomy (Pauwel's operation II). Their study was carried out on 80 patients in whom the disease was of sufficient duration. The authors recall the main principles of biomechanics that must be strictly applied following careful and detailed study of the radiological films and of the results of the pre-operative test: failure to do this will lead to failure in treatment. The cases that are usually improved by the Pauwels II operation are those arthroses with a flattened head or with gout, often dislocated. The authors describe the surgical technique and the postoperative treatment. They obtained very good or good results in 85 percent of cases, and unsatisfactory results in 15 percent of patients, mainly because of errors at beginning of the series. As with varus, osteotomy, these operations must be regarded as surgery to relieve restrictions on movement and not surgery to restore shape.
