Aims

High-quality clinical research in children’s orthopaedic surgery has lagged behind other surgical subspecialties. This study used a consensus-based approach to identify research priorities for clinical trials in children’s orthopaedics.

The purpose of this study was to evaluate the long-term outcome of adults with spina bifida cystica (SBC) who had been treated either operatively or non-operatively for scoliosis during childhood.

We reviewed 45 patients with a SBC scoliosis (Cobb angle ≥ 50º) who had been treated at one of two children’s hospitals between 1991 and 2007. Of these, 34 (75.6%) had been treated operatively and 11 (24.4%) non-operatively. After a mean follow-up of 14.1 years (standard deviation (sd) 4.3) clinical, radiological and health-related quality of life (HRQOL) outcomes were evaluated using the Spina Bifida Spine Questionnaire (SBSQ) and the 36-Item Short Form Health Survey (SF-36).

Although patients in the two groups were demographically similar, those who had undergone surgery had a larger mean Cobb angle (88.0º (sd 20.5; 50.0 to 122.0); versus 65.7º (sd 22.0; 51.0 to 115.0); p < 0.01) and a larger mean clavicle–rib intersection difference (12.3 mm; (sd 8.5; 1 to 37); versus 4.1 mm, (sd 5.9; 0 to 16); p = 0.01) than those treated non-operatively. Both groups were statistically similar at follow-up with respect to walking capacity, neurological motor level, sitting balance and health-related quality of life (HRQOL) outcomes.

Spinal fusion in SBC scoliosis corrects coronal deformity and stops progression of the curve but has no clear effect on HRQOL.

The Ponseti method of clubfoot management requires a period of bracing in order to maintain correction. This study compared the effectiveness of ankle foot orthoses and Denis Browne boots and bar in the prevention of recurrence following successful initial management. Between 2001 and 2003, 45 children (69 feet) with idiopathic clubfeet achieved full correction following Ponseti casting with or without a tenotomy, of whom 17 (30 clubfeet) were braced with an ankle foot orthosis while 28 (39 clubfeet) were prescribed with Denis Browne boots and bar. The groups were similar in age, gender, number of casts and tenotomy rates. The mean follow-up was 60 months (50 to 72) in the ankle foot orthosis group and 47 months (36 to 60) in the group with boots and bars. Recurrence requiring additional treatment occurred in 25 of 30 (83%) of the ankle foot orthosis group and 12 of 39 (31%) of the group with boots and bars (p < 0.001). Additional procedures included repeat tenotomy (four in the ankle foot orthosis group and five in the group treated with boot and bars), limited posterior release with or without tendon transfers (seven in the ankle foot orthosis group and two in the group treated with boots and bars), posteromedial releases (nine in the orthosis group) and midfoot osteotomies (five in the orthosis group, p < 0.001).

Following initial correction by the Ponseti method, children managed with boots and bars had far fewer recurrences than those managed with ankle foot orthoses. Foot abduction appears to be important to maintain correction of clubfeet treated by the Ponseti method, and this cannot be achieved with an ankle foot orthosis.

Slipped capital femoral epiphysis may be associated with hypothyroidism and other endocrinopathies. Routine screening for such abnormalities is unlikely to be cost-effective since the overall incidence of these disorders, in association with slipped capital femoral epiphysis, is low. The identification of a presenting characteristic which would predict the chance of an associated endocrinopathy would allow only selected children to be screened.

Our aim was to determine if certain characteristics were useful as a screen for patients with an underlying endocrinopathy who presented with slipped capital femoral epiphysis. Between January 1988 and December 1996 we recorded gender, age, height, unilateral or bilateral involvement and an associated diagnosis of endocrinopathy for all patients who were treated for slipped capital femoral epiphysis. Of 166 such patients 13 (7.8%) had an endocrinopathy. Height was the only useful screening characteristic, although bilateral involvement was more likely in those with an endocrinopathy. Most (90.9%) of this latter group were below the tenth percentile for height compared with only 5.4% in those who did not have an endocrinopathy (p < 0.005). The sensitivity and negative predictive value of detecting an underlying endocrinopathy in a patient presenting with a slipped capital femoral epiphysis and short stature (tenth percentile or less) were 90.2% and 98.6%, respectively.

Patients who are on or below the tenth percentile for height at the time of presentation should be screened for a possible endocrine abnormality using measurement of thyroid-stimulating hormone and free thyroxine as a preliminary screening test. These hormones are most likely to be abnormal in the presence of endocrine dysfunction.

We reviewed 52 children, born between 1974 and 1985 with spina bifida affecting L3 and L4, who had dislocated hips. Their motor function was stable and they were able to walk at the time of dislocation. They were interviewed and examined physically and radiologically. Physical function was measured by the Rand Health Insurance Study questionnaire (HIS), the Childhood Health Assessment questionnaire (CHAQ), and by determining the functional level of ambulation according to Hoffer et al (1973). In a subgroup of 12 patients with L4 level of involvement from both treatment groups we measured the metabolic energy consumption while walking.

Thirty patients (49 hips) had been treated by operative relocation and 22 conservatively. Ten of the hips treated by operation subluxated or redislocated. The function in the two groups (conservative v operated) was similar (HIS score 7.8 v 8.0, p = 0.45; CHAQ 14 v 13, p = 0.2; level of mobility 0.61 v 0.63, p = 0.5). Patients in whom operation had failed had worse function than did those with successful surgery (HIS score 8.8 v 6.1, p = 0.025) and those with successful surgery had better function than patients treated conservatively (HIS score 8.8 v 8.0, p = 0.15). Function in patients with failed operations, however, was worse than in those who did not have surgical treatment (HIS score 6.6 v 7.8, p = 0.07). In the 12 so examined the operated group had a 30% more energy-efficient gait (0.271 v 0.361 ml O₂ kg/m, p = 0.05).

Patients with failed operations had worse function than those who were not operated on. The benefit of surgical relocation of the dislocated hips was marginal.
