Aims

The health-related quality of life (HRQoL) of paediatric patients with orthopaedic conditions and spinal deformity is important, but existing generic tools have their shortcomings. We aim to evaluate the use of Paediatric Quality of Life Inventory (PedsQL) 4.0 generic core scales in the paediatric population with specific comparisons between those with spinal and limb pathologies, and to explore the feasibility of using PedsQL for studying scoliosis patients’ HRQoL.

Aims

Iliac wing (Type I) and iliosacral (Type I/IV) pelvic resections for a primary bone tumour create a large segmental defect in the pelvic ring. The management of this defect is controversial as the surgeon may choose to reconstruct it or not. When no reconstruction is undertaken, the residual ilium collapses back onto the remaining sacrum forming an iliosacral pseudarthrosis. The aim of this study was to evaluate the long-term oncological outcome, complications, and functional outcome after pelvic resection without reconstruction.

The Fulkerson osteotomy has proved to be a reliable treatment for subluxation of the patella due to malalignment. Aggressive rehabilitation in the early postoperative period is unwise since the proximal tibia is weakened by the oblique osteotomy. Early weight-bearing and unrestricted activity have caused fractures in a few patients. Even late in the postoperative period the osteotomy may adversely influence the biomechanical properties of the proximal tibia. We describe two athletes who sustained a fracture of the proximal tibia, during recreational activities, six months after a Fulkerson osteotomy. Both had been bearing full weight for about ten weeks without complaint. Bony healing of the osteotomy had been demonstrated on plain radiographs at ten and at 12 weeks. After a Fulkerson osteotomy, jogging and activities which impose considerable impact force should be discouraged for at least nine to 12 months

We reviewed the results of 277 intertrochanteric valgus-extension osteotomies performed between 1973 and 1975 for primary or secondary osteoarthritis. The average age of the patients was 51 years and follow-up varied from 11 to 15 years. At the latest evaluation 67% of the hips were good or excellent on the Merle D'Aubigne scale. Better results were obtained in patients under 40 years of age with unilateral involvement and a mechanical (secondary) aetiology. An elliptical femoral head, minimal subluxation and an adequate pre-operative range of motion were also favourable. There was radiographic evidence of regression of the arthritic changes in 39% of the hips at final review. Valgus-extension osteotomy is effective for secondary osteoarthritis of the hip in selected younger patients, but not for those with primary hip disease or a poor range of movement

Shoulder arthrodesis is often used to treat flail shoulder after a brachial plexus injury, but has a high complication rate and entails loss of passive mobility. We have reviewed 27 patients with brachial plexus injury treated by transfer of the trapezius to the proximal humerus at an average time from injury of 31.3 months. Pre-operatively, all 27 shoulders were subluxated, with an average abduction of 3.5 degrees. Postoperatively, shoulder abduction averaged 45.4 degrees, and subluxation was abolished. All patients were satisfied with their improvement in function. Trapezius transfer is recommended as a simple procedure that requires only a brief period in hospital, allows early rehabilitation, and gives a satisfactory outcome, while retaining passive mobility of the shoulder

Objectives

This review aims to summarize the outcomes used to describe effectiveness of treatments for paediatric wrist fractures within existing literature.

Some arthritic knees with varus deformity show excessive valgus angulation of the femoral joint surface with proximal tibia vara. This causes a downward and medial inclination of the articular surfaces in the coronal plane. The patients we studied had a medial shift of the standing load-bearing axis, and arthritic changes mainly in the medial compartment. Some also had lateral tibial subluxation with twisting of the distal femur and proximal tibia in opposite directions. We assessed the articular geometry by precise radiographic analysis, and compared the results with those in normal volunteers and a group of osteoarthritic patients. The prevalence of this type of deformity in our osteoarthritic patients was 11.5%; its recognition allows the use of specific operative correction that may include double osteotomy or the precise orientation of prosthetic components

To determine the natural history of dislocation of the hip in cerebral palsy, and to evolve methods to predict dislocation, the notes and radiographs of 462 patients with cerebral palsy were reviewed. Dislocation occurred in 10% of patients by progressive migration and subluxation of the proximal femur in the presence of acetabular dysplasia. Statistical analysis identified the radiographic features that helped to predict dislocation. Measurement of acetabular index, by a method that allows for rotation of the acetabulum, was the most powerful single predictor. Measurement of this index at two and four years of age could identify patients who would dislocate unless effective treatment was undertaken, those at risk of dislocation only if scoliosis developed, and those who would not dislocate. On the basis of this method of screening for dislocation, a logical system of surgical prophylaxis is proposed

We studied the morphological changes in the proximal femur in 42 patients (42 hips) who had had varus derotation osteotomy of the upper femur for residual acetabular dysplasia and congenital subluxation of the hip and who did not show deformity of the head of the femur. In 19 patients the alignment of the whole leg was examined. The femoral neck-shaft angle (FNSA) at the final examination was unrelated to that immediately after operation or to the state of the acetabulum at that time. The postoperative FNSA was not related to the final result but the CE angle obtained at surgery influenced the outcome. The femoral length did not differ significantly between the unaffected and affected sides. Significant differences were found in the femorotibial angle (176.6 degrees v 174.5 degrees) and in the point of intersection between the mechanical axis and knee (65.0% v 57.2%)

Hereditary multiple exostoses is an autosomal dominant disorder characterised by multiple osteochondromata, most commonly affecting the forearm, knee and ankle. Osteochondromata of the proximal femur have been reported to occur in 30% to 90% of affected patients with coxa valga in 25%. Acetabular dysplasia is rare but has been described. This is the first report of a patient requiring surgical intervention. A girl was seen at the age of nine with hereditary multiple exostoses and when 12 developed bilateral pain in the groin. Radiographs showed severely dysplastic acetabula with less than 50% coverage of the femoral heads and widening of the medial joint space. Large sessile osteochondromata were present along the medial side of the femoral neck proximal to the lesser trochanter, with associated coxa valga. The case illustrates the importance of obtaining initial skeletal surveys in children with hereditary multiple exostoses to identify potential problems such as acetabular dysplasia and subluxation of the hip

In this prospective study, 35,550 neonates were examined shortly after birth by a team of orthopaedic surgeons. They diagnosed 775 unstable or dislocated hips in 656 babies; there were two teratological dislocations. Treatment was first with a Frejka pillow and, if this failed to give a normal hip, a Pavlik harness at three months. Early clinical examination did not identify 21 infants who were found to have subluxation or dislocation of the hip at the three-month review. The number of missed cases declined during the study, however, reflecting the increasing experience of the examiners. One case of avascular necrosis occurred in the group treated from birth and one in the late-diagnosed group. Open reduction was necessary only in the two teratological dislocations. Experienced examiners are needed for accurate clinical diagnosis; and treatment should be started before the baby is discharged from the maternity ward

Aims

The aims of this study were to determine the effect of osteophyte excision on deformity correction and soft tissue gap balance in varus knees undergoing computer-assisted total knee arthroplasty (TKA).

Isolated dislocations of the navicular are rare injuries; we present our experience of six cases in which the navicular was dislocated without fracture. All patients had complex injuries, with considerable disruption of the midfoot. Five patients had open reduction and stabilisation with Kirschner wires. One developed subluxation and deformity of the midfoot because of inadequate stabilisation of the lateral column, and there was one patient with ischaemic necrosis. We believe that the navicular cannot dislocate in isolation because of the rigid bony supports around it; there has to be significant disruption of both longitudinal columns of the foot. Most commonly, an abduction/pronation injury causes a midtarsal dislocation, and on spontaneous reduction the navicular may dislocate medially. This mechanism is similar to a perilunate dislocation. Stabilisation of both medial and lateral columns of the foot may sometimes be essential for isolated dislocations. In spite of our low incidence of ischaemic necrosis, there is always a likelihood of this complication

The work capacity of 26 women after a Chiari pelvic osteotomy for symptomatic unilateral subluxation of the hip was assessed using two simple exercise tests: the maximal walking speed during a 12-minute test and the time taken to climb stairs. A significant linear decline in walking speed occurred with increasing age, despite the operation, and only one patient over the age of 25 years was able to walk at a normal rate. Compared to the results in a control group of women of similar age the stair climbing time was increased in 54 per cent of the patients and showed a significant negative correlation with the maximal walking speed. Age-adjusted walking speed was closely associated with the degree of pain experienced but there was no relationship between observed function and conventional clinical assessment based on the range of movement and the radiographic appearances of the hip

Shelf arthroplasty is briefly reviewed in historical perspective and the results in 45 hips (39 patients) which had undergone this procedure at the Royal Children's Hospital are presented. The majority of these patients were adolescents who had previously been treated for congenital dislocation or subluxation of the hip. The indications for operation and the operative technique are discussed. Clinical examination was carried out upon 33 of the 39 patients at an average of 11 years after operation. The results suggested that where pain had been an indication for operation almost 80 percent of the hips remained relatively free of symptoms at the time of follow-up and in those patients where acetabular dysplasia had been an indication, the coverage remained good and pain had not appeared. It is concluded that the shelf operation is useful for dealing with both pain and dysplasia in the adolescent

1. Synovitis was induced in the hip joints of fifty-six rabbits by the intra-articular injection of surgical talc. The opposite hip joint and eleven suitable"sham" operations served as controls. 2. The results in the hips injected with talc were as follows. Widening of the medial joint space and sometimes acetabular changes were seen; enlargement of the femoral head and neck in two planes was found, with, in most cases, flattening of the superior aspect of the head; there was thickening of the joint cartilage and sometimes deformity of the capital epiphysis; thickening of the cartilage was the main cause of the coxa magna, cervix magna and ischium magnum. 3. The embryology, micro-anatomy and development of the hip joint is reviewed and attention is drawn to the configuration of the layers of germinal cartilage cells. The effect of an induced synovitis in producing hyperplasia of the joint cartilage, incongruity of the articulating surfaces and subsequent subluxation is discussed

1. Forty-eight paralytic dislocations of the hip have been studied and twenty-seven operations for correction of valgus deformity of the femoral neck have been done. 2. The differing features of dislocations occurring in poliomyelitis, cerebral palsy and meningomyelocoele are considered in relation to management after operation. 3. Early recognition of subluxation is essential to a successful varus osteotomy. An angle of 105 degrees rather than the 120 degrees previously recommended is advisable for children under the age of five. 4. Redislocation is most likely to occur in meningomyelocoele in which muscular imbalance is greatest, and in later cases where the acetabulum has become shallow by growth without the femoral head within it. It has not occurred as a late complication after weight bearing has been established, from a recurrence of valgus deformity

1. Attention is drawn to that type of rigid congenital flat foot in which the talus lies vertically instead of horizontally. 2. This deformity is rare, but if not treated successfully leads to an ugly, painful foot in adolescence. 3. The experience of five patients forms the basis of the present preliminary account. One adolescent and two young children under the age of five were treated unsuccessfully by both conservative and operative measures. More recently in two children with bilateral deformity open operation has been successful in restoring the shape of the foot. 4. The operation is essentially a reduction of a subluxation at the talo-navicular and subtalar joints. It entails freeing the head of the talus sufficiently to allow it to be lifted dorsally and laterally. The talus is then anchored in position by transplanting the distal end of the peroneus brevis tendon through the neck of the bone

Spondylolisthesis without a defect in the neural arch, the "pseudo-spondylolisthesis" of Junghanns, usually affects the fourth lumbar vertebra. The essential lesion is an increase in the angle between tile inferior facets and the pedicles which allows subluxation at the inferior joints. The forward displacement averages less than one centimetre. It commonly produces a clinical picture of backache and sciatica, but may present with. a "drop foot," and in unusual instances compression of the cauda euluina may occur. Patients seen in the early stages without signs of nerve root compression are best treated by localised spinal fusion. Late fusion may afford no relief because of secondary changes in the spine, but these patients obtain some benefit from a corset. Laminectomy is indicated for severe symptoms in patients who show signs of nerve root compression; it should be followed by spinal fusion
