To investigate the effect of soft tissue release (STR) and the length of postoperative immobilisation on the long term outcomes of closed reduction (CR) of the hip for developmental dysplasia of the hip. 77 hips (72 patients) who had undergone closed reduction (CR) between 1977-2005 were studied retrospectively to review their outcome (Severin grade), identify the reasons for failure and to assess factors associated with residual dysplasia. Particular attention was paid to the use of a STR at the time of CR (to improve initial hip stability) and the duration of postoperative immobilisation.Purpose
Materials
To document the incidence and nature of complications associated with hemiepiphysiodesis using a screw and plate device (8-plate, Orthofix). We reviewed case notes and radiographs of 71 children (130 segments) with lower limb deformities treated with temporary hemiepiphyseal arrest using the 8-plate. 96% of deformities were in the coronal plane, 4% sagittal. 72% of coronal deformities demonstrated valgus malalignment. We defined three types of complications: complications Complications were related to variables of patient age, gender, diagnosis, location of deformity and associated surgery.Purpose
Methods
Following the cuneiform osteotomy, patients were mobilized partial weight bearing for 8 weeks. At a mean 12 month follow up, radiographs confirmed that all oste-otomies had united and no hip showed evidence of AVN.
Patients were reviewed clinically and completed questionnaires documenting pain, function and satisfaction before and after treatment at a mean follow-up of 44 months (range 14–131). All patient’s notes and radiographs were examined.
Complications included almost universal minor pin-site infections, flexion contractures of the toes in 5 feet and skin ulceration in 2 feet, 1 requiring a muscle flap.
Scoliosis and hip subluxation/dislocation are common and often coexistent problems encountered in patients with cerebral palsy (CP). The underlying mechanism may be related to muscle imbalance. Surgical correction may become necessary in severe symptomatic cases. The effect of surgical correction of one deformity on the other is not well understood. We retrospectively reviewed a series of 17 patients with total body cerebral palsy with diagnoses of both scoliosis and hip subluxation who had undergone either surgical correction of their scoliosis (9 patients) or a hip reconstruction to correct hip deformity (8 patients). In all patients, the degree of progression of both deformities was measured, radiographically, using the Cobb angle for the spine and the percentage migration index for hip centre of rotation at intervals before and at least 18 months post surgery. All patients who underwent scoliosis correction had a progressive increase in the percentage of hip migration at a rate greater than that prior to scoliosis surgery. Similarly, patients who underwent a hip reconstruction procedure demonstrated a more rapid increase in their spine Cobb angles post surgery. There may be a relationship between hip subluxation/dislocation and scoliosis in CP patients. Surgery for either scoliosis or hip dysplasia may in the presence of both conditions lead to a significant and rapid worsening of the other. The possible negative implications on the overall functional outcome of the surgical procedure warrants careful consideration to both hip and the spine before and after surgical correction of either deformity. In selected cases there may be an indication for one procedure to follow soon after the other.
Highly active anti-retroviral therapy has transformed HIV into a chronic disease with a long-term asymptomatic phase. As a result, emphasis is shifting to other effects of the virus, aside from immunosuppression and mortality. We have reviewed the current evidence for an association between HIV infection and poor fracture healing. The increased prevalence of osteoporosis and fragility fractures in HIV patients is well recognised. The suggestion that this may be purely as a result of highly active anti-retroviral therapy has been largely rejected. Apart from directly impeding cellular function in bone remodelling, HIV infection is known to cause derangement in the levels of those cytokines involved in fracture healing (particularly tumour necrosis factor-α) and appears to impair the blood supply of bone. Many other factors complicate this issue, including a reduced body mass index, suboptimal nutrition, the effects of anti-retroviral drugs and the avoidance of operative intervention because of high rates of wound infection. However, there are sound molecular and biochemical hypotheses for a direct relationship between HIV infection and impaired fracture healing, and the rewards for further knowledge in this area are extensive in terms of optimised fracture management, reduced patient morbidity and educated resource allocation. Further investigation in this area is overdue.
Percutaneous drill epiphyseodesis is an effective method of achieving physeal ablation with no significant complications. While the growth remaining method is a crude estimate of the timing of epiphyseodesis, it was accurate in the majority of cases in this small series. The determination of skeletal age was found to be a useful adjunct to management in a small proportion of cases.
Purpose: To review the orthopaedic manifestations and document the results of surgical intervention. Material and Methods: A review of all 22 children currently attending a specialist scleroderma clinic was performed. Disease extent was measured in terms of percentage body surface area (BSA) affected and all orthopaedic abnormalities were documented. The outcome of surgical intervention was evaluated. Results: All children presented by the age of 12 and all but 2 had developed joint contractures of either the lower or upper limbs affecting function within 2yrs of diagnosis. Overall, lower limbs were more commonly affected than upper. Abdominal scleroderma led to a scoliosis in 75% of cases. The mean BSA affected was 35% (range 5-65%) with contractures more related to site of disease rather than extent. Pain was associated with lower limb contractures and loss of function with hand contractures. Limb length discrepancy (LLD) was common with a mean of 3cms (range 2-6.5cms). 8 children have had surgery. 7 developed wound healing problems. 50% of operations failed to correct the deformity and in a further 25% relapse has occurred. In the remaining 2 cases a good result was achieved. In addition, one epiphysiodesis has been performed and 3 are planned. Conclusions: This is the largest known review of children with linear scleroderma. Joint contractures are common but poorly managed by conservative methods alone. Surgical intervention is difficult but early defini-tive treatment is recommended with subsequent aggressive splinting during growth whilst the disease is active. LLD must be corrected.
The purpose of the study was to perform an independent assessment of the results of open reduction and internal fixation (ORIF) on a selected group of displaced intra-articular calcaneal fractures from two centres. It still remains controversial whether to manage intraarticular calcaneal fractures conservatively or operatively with few long-term results. The identification of patients who may benefit from the procedure is still undecided. Fifty fractures in 46 patients with a defined significant displacement of an intra-articular fracture of the calcaneum underwent ORIF by one of the two senior authors. Mean age at operation was 46 years and mean follow-up was 44 months. 88% of the injuries were due to a fall from a height. 30% of the patients had contralateral foot/ankle injuries, and 20% of the patients developed a superficial wound infection. The infection rate was significantly higher in patients whose surgery was delayed more than 14 days. All patients were independently reviewed after a minimum two-year follow-up. A clinical, radiographic and subjective assessment of the outcome was made. The results were correlated to the original fracture type. The mean Atkins score was 88 (out of 100). Bilateral injuries fared worse. Heel pain at follow-up correlated with a poor score. Atkins scores over 90 occurred in 77% of Saunders Type II, 50% in Type III, and 43% in Type IV fractures. 94% returned to work at a mean of 10 months post-injury. Three patients have undergone a subtalar arthrodesis – two for persistent pain and one for a significant malunion. One patient required a flap but there have been no cases of chronic osteomyelitis. In patients with significantly displaced fractures, ORIF is a worthwhile procedure with 90% of patients satisfied and 94% returning to work. Gross articular comminution does not preclude a good/excellent result if hindfoot alignment is restored. ORIF after fourteen days should be avoided due to the high risk of infection.

We have developed a clinical method for the graphic recording, analysis and planning of treatment of leg-length discrepancy during growth. Initially, the clinically determined discrepancy is plotted against the chronological age yearly, and then in late childhood at six-monthly intervals. CT and measurements of skeletal age are made in middle and late childhood to confirm the clinical findings. In a prospective study in 20 children, we observed that only eight had a linear increase in discrepancy. The observed pattern of increase was therefore used to estimate the mature discrepancy. Epiphyseodesis reference slopes were used to determine the most appropriate time and type of epiphyseodesis. In all children, the leg-length discrepancy at maturity was within 1 cm of the predicted amount. Changes in discrepancy due to leg lengthening or correction of deformity were also plotted graphically. We conclude that the clinical graphic method is simple to use, takes into account the varying patterns of discrepancy, and minimises radiation dosage.
We have studied the radiographic and CT features of 120 displaced intra-articular fractures of the calcaneum in order to define the pathological anatomy. In 96% of cases, the CT scans identified three main fragments: sustentacular, lateral joint and body. The sustentacular fragment was often rotated into varus, the lateral joint fragment into valgus and the body fragment impacted upwards, in varus and displaced laterally. The displacement of these fragments varied according to which of three fracture types was present, as defined by the composition of the fractured lateral wall of the calcaneum. In type 1 it was formed by the lateral joint fragment alone; in type 2 by both body and lateral joint fragments; and in type 3 by the body fragment alone. Fracture fragment displacement differs from that previously described, in that true uniform depression of the lateral joint fragment is rare.
The classification of intra-articular fractures of the calcaneum described in part I is related to an operative approach which allows accurate reduction and stable fixation of the fracture fragments. An extended lateral incision is used to avoid sural nerve damage and problems of soft-tissue healing. In type 3 fractures, access to the lateral joint fragment requires an osteotomy of the lateral wall, but after this the lateral joint fragment can be rotated out of the subtalar joint to allow transcalcaneal reduction of the medial wall. Reduction of the body fragment and lateral joint fragment on to the sustentacular fragment allows the three fragments to be stabilised by a 3.5 mm Y-shaped reconstruction plate. Our early results have been successful in terms of fracture reduction and the restoration of heel shape and joint congruity, but extended follow-up will be necessary to define the indications for this difficult procedure.
The results of treatment in 242 patients with intracapsular fractures of the neck of femur treated with Garden screws are presented with reference as to whether the screws were crossed or parallel. The incidence both of nonunion and of avascular necrosis was less in those fractures treated with parallel screws. The outcome was also superior if the reduction was good.
