We describe the results of a policy of highly selective splintage for CDH, using knee plasters. No child suffered because splintage was withheld. In those who were treated the results were satisfactory and the proportion who required a subsequent operation was extremely low. Avascular necrosis was not a significant problem. The method, although a little more time consuming, appears to offer significant advantages over current alternatives.
A retrospective study of the development of the hip opposite a congenitally dislocated hip was carried out to identify at an early age those hips which would develop abnormally. Recognised radiological measurements were used showing the development of the joints with age. The development was compared with that of a control group of normal hips. Single measurements were shown to be unreliable in predicting the development of the hip. A simple hip ratio is proposed which predicts, at an early age and with a high degree of accuracy, the developmental outcome.
Six boys were examined during the second year of life, each with symptoms in one hip. The affected femoral capital epiphysis was smaller or more irregular (or both) than that of the unaffected hip but was neither subluxed nor dislocated. The subsequent radiographs revealed changes similar to those in severe Perthes' disease. Nevertheless, we give reasons for believing that this disorder in boys under two years of age should be distinguished from Perthes' disease.
The results in 102 acetabuloplasties have been assessed in eighty-six patients, with a minimum follow-up of five years. Clinical and radiological assessment was carried out according to a score system very similar to that used in previous studies, and the results were expressed as excellent, good, fair and poor according to the score obtained. Any hip requiring further stabifising procedures was automatically grouped as a failure. Subtrochanteric femoral osteotomy was used when femoral anteversion was excessive. The results revealed that 73 per cent of the hips were satisfactory (excellent or good) overall, but that a steady deterioration was evident when the five-and fifteen-year groups were compared. Few of the hips were regarded as normal on radiological grounds. Homologous bone bank rib was found to be the most satisfactory graft material. Coxa magna was the most common abnormality that was consistent with a good or excellent result. Avascular necrosis of the femoral head was found in only six hips; it was more commonly present in patients subjected to previous operation. Concentric reduction of the femoral head is essential if acetabuloplasty is to maintain stability of the hip.
1. The treatment is described of a consecutive series of fourteen patients suffering from rheumatoid arthritis causing a slip of the cervical vertebrae, mainly at the C.1-2 level, and a cord lesion. 2. The importance of a change of symptoms and signs in these patients, especially the occurrence of the so-called "alarm signs", is stressed. 3. In twelve patients the combination of this kind of cervical instability with a cord lesion was treated by fusion, most frequently of occiput to C.2 and 3. 4. In the eleven patients who survived the operation the results with a follow-up period of one to eight years are considered highly gratifying. 5. Technical details and various problems associated with treatment are discussed.
The management of a personal series of over 500 patients with congenital hip dislocations has been reviewed with special reference to the mistakes that have been made and the safeguards which have now been adopted.
In this review of 106 cases it appears that immobilisation of a contracted, dislocated or subluxated hip in an extreme position in plaster as the initial treatment caused vascular damage to the femoral epiphysis in approximately 50 per cent of cases. Preliminary frame reduction in the dislocated hips slowly stretches the soft tissues and allows adaptation of the vessels to the position required for reduction. Open reduction would seem to reduce the incidence of osteochondritic changes. When a hip is immobilised in plaster the extreme of any position, particularly with regard to rotation, should be avoided.
1. A method of treatment of the congenitally dislocated hip is described. 2. The rationale of the treatment is considered. 3. The subsequent development of the hip generally, and of its individual components, is described. 4. Comparison between the results of other methods of treatment and of this method is not attempted for reasons stated. 5. The advantages of a shortened period of splintage are discussed. 6. The state of fifty completely dislocated hips treated consecutively is described at the end of a follow-up period of from three to seven and a half years.
SummaryâFifty-two cases of exposure of the glenoid labrum are recorded. Fifty-one operations with anterior exposure, followed by capsular reefing and shortening of the subscapularis, were successful. One operation with superior exposure, and without capsular reefing or shortening of the subscapularis, was unsuccessful.
