Description

As the magnitude of resection increases, the ability to correct deformity improves, but also the risk of complication increases. Therein, an understanding of potential applications and complications is helpful. The technique for accurate biplane osteotomy at the level of the lesser trochanter for the treatment of slipped capital femoral epiphysis by making reasonably accurate roentgen graphic measurements is described and illustrated. He is best remembered for his work on osteotomy of the upper end of the femur, particularly the pelvic support osteotomy.

Turnbuckle

Full correction of the deformity was attempted only under controlled conditions after the patient was fully awake and after the spine was securely immobilized in a full spinal brace equipped with a jury-mast and a turnbuckle to raise the chin. The turnbuckle was unthreaded slowly and the cervical spine was extended in stages while the patient was closely observed and frequently examined to test her sensory perceptions, reflexes, and muscle power. The problem of instability of reduction of congenital dislocation and congenital subluxation of the hip has been studied. The basic cause of this instability is the abnormal direction in which the entire acetabulum faces. An operation, innominate osteotomy, has been designed to correct the abnormal direction of the entire acetabulum. The principle of innominate osteotomy is redirection of the acetabulum so that the reduced dislocation or subluxation, which was stable previously only in the position of abduction and flexion, is rendered stable in the functional position of weight-bearing. Some clinical and other observations are made on cavus deformity of the foot, and a new surgical procedure is presented for the correction of anterior pes cavus. This procedure includes fasciotomy in the sole according to the technique of Steindler and a V-osteotomy of the tarsus that permits the correction of deformity at the most prominent point without the disadvantages of the classic techniques (shortening of the foot, delay in consolidation, and interference with tarsal motion). The results in seventeen feet followed for from two to six years have been encouraging. Widening of the ankle mortise following fracture can be a subtle diagnosis requiring special radiographs to fully appreciate the extent of shortening and rotation of the fibula. Once this fibular shortening has been recognized, a lengthening and rotational osteotomy can be conducted with use of a special compression/distraction device and bone graft. A series of 23 cases demonstrates that reconstructive lengthening osteotomy is well worthwhile when there is absent or minimal osteon-arthritic change, irrespective of the time from the original injury. Most osteoarthritis of the hip results from chronic abnormal hip mechanics often associated with instability, impingement, or combinations of instability and impingement

Osteoarthritis

The ethology of the mechanical problems in many hips is a surgically treatable anatomic abnormality, often a developmental deformity (dysplasia, Perthes disease, slipped epiphysis, femoral or acetabula retroversion, or reduced headneck offset). The rationale of mechanically-based measures to prevent or treat osteoarthritis assumes the following: Correctable mechanical overload is a major etiologic factor in osteoarthritis; and relief of the mechanical overload can prevent or improve osteoarthritis. The success of such mechanicallybased joint-preserving measures depends largely on the completeness with which the joint-preserving treatment normalizes the mechanical environment of the hip. A limiting factor often is the amount of irreversible articular damage that is present at the time treatment is begun. Articles have been published regarding Smith-Petersen osteotomies, pedicle subtraction procedures, and vertebral column resections. Expectations and complications have been reviewed. However, decision-making regarding which of the 3 procedures is most useful for a particular spinal deformity case is not clearly investigated.

Fairly centered joints and decentered joints with an elongated acetabulum had a high percentage of normal and slightly pathologic values. In false acetabuli and high dislocations, this rate was diminished. Measurements of acetabular rotation that guarantee greatest pain relief have been evaluated for the future. In forty-five patients, twenty-three with congenital dislocations and the rest with paralytic or other disturbances, this new displacement osteotomy of the hip joint was done when other iliac osteotomies were considered ineffective. The patients seven to seventeen years old were followed two to ten years. Of the fiftytwo procedures, forty were satisfactory. Most of the unsatisfactory results were in cases of myelodysplasia, peroneal atrophy, and cerebral palsy.
