[Initial Experience with Morscher's Elongation Osteotomy in Coxa Brevis.].

The authors present their initial experience with triple osteotomy of the proximal femur with elongation of the neck of the coxa brevis. The objective of elongation osteotomy is to achieve sufficiency of the abductors after reduction and distalization of the greater trochanter and to improve the biomechanics of the hip joint. The same indication applies to double intertrochanteric Wagner or Dungle osteotomy which achieves also similar results. At the Orthopaedic Clinic of the Medical Faculty, Palacký University Olomouc in the course of 13 months eight patients were operated. The authors describe briefly the surgical procedure, explain the necessity of a certain modification during the final stage of operation during adjustment and refixing of the reduced greater trochanter. They discuss the indication spectrum, explain why they do not use simple transposition of the greater trochanter and mention the possibility of subsequent osteotomy of the pelvis or plastic operation of the tectum in case of concomittant acetabular dysplasia. Key words: coxa brevis, triple osteotomy, elongation of the neck of the femur, reduction and distalization of the greater trochanter.
