Femoral Fractures in Adolescents: A Comparison of Four Methods of Fixation

BACKGROUND The optimal management of femoral fractures in adolescents is controversial. This study was performed to compare the results and complications of four methods of fixation and to determine the factors related to those complications. METHODS We conducted a retrospective cohort study of 194 diaphyseal femoral fractures in 189 children and adolescents treated with elastic stable intramedullary nail fixation, external fixation, rigid intramedullary nail fixation, or plate fixation. After adjustment for age, weight, energy of the injury, polytrauma, fracture level and pattern, and extent of comminution, treatment outcomes were compared in terms of the length of the hospital stay, time to union, and complication rates, including loss of reduction requiring a reoperation, malunion, nonunion, refracture, infection, and the need for a reoperation other than routine hardware removal. RESULTS The mean age of the patients was 13.2 years, and their mean weight was 49.5 kg. There was a loss of reduction of two of 105 fractures treated with elastic nail fixation and ten of thirty-three treated with external fixation (p < 0.001). At the time of final follow-up, five patients (two treated with external fixation and one in each of the other groups) had >or=2.0 cm of shortening. Eight of the 104 patients (105 fractures) treated with elastic nail fixation underwent a reoperation (two each because of loss of reduction, refracture, the need for trimming or advancement of the nail, and delayed union or nonunion). Sixteen patients treated with external fixation required a reoperation (ten because of loss of reduction, one for replacement of a pin complicated by infection, one for débridement of the site of a deep infection, three because of refracture, and one for lengthening). One patient treated with a rigid intramedullary nail required débridement at the site of a deep infection, and one underwent removal of a prominent distal interlocking screw. One fracture treated with plate fixation required refixation following refractures. A multivariate analysis with adjustment for baseline differences showed external fixation to be associated with a 12.41-times (95% confidence interval = 2.26 to 68.31) greater risk of loss of reduction and/or malunion than elastic stable intramedullary nail fixation. CONCLUSIONS External fixation was associated with the highest rate of complications in our series of adolescents treated for a femoral fracture. Although the other three methods yielded comparable outcomes, we cannot currently recommend one method of fixation for all adolescents with a femoral fracture. The choice of fixation will remain influenced by surgeon preference based on expertise and experience, patient and fracture characteristics, and patient and family preferences.

A comparison of ankle foot orthoses with foot abduction orthoses to prevent recurrence following correction of idiopathic clubfoot by the Ponseti method

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.

Comparison of Surgeon and Physiotherapist-Directed Ponseti Treatment of Idiopathic Clubfoot

BACKGROUND Increasingly, the Ponseti method has been adopted worldwide as the preferred method of managing idiopathic clubfoot deformity. Following the successful implementation of the Ponseti method by orthopaedic surgeons in our institution, a clubfoot clinic was established in 2003. This clinic is directed by a physiotherapist who, using the Ponseti protocol, performs the serial cast treatment and supervises the brace management of all children with idiopathic clubfoot deformity. The purpose of this study was to compare the outcomes of physiotherapist-directed with surgeon-directed Ponseti cast treatment of idiopathic clubfeet. METHODS We performed a retrospective cohort study of all patients with idiopathic clubfoot deformity treated from 2002 to 2006 and followed for a minimum of two years. Twenty-five children (thirty-four clubfeet) treated by surgeons were compared with ninety-five children (137 clubfeet) treated by a physiotherapist. The outcomes that were evaluated included the number of casts required, the rate of percutaneous Achilles tenotomy, the rate of recurrence, the failure rate, and the need for additional surgical procedures. RESULTS At the time of presentation, the patients in the two groups were similar in terms of age, sex distribution, laterality of the clubfoot, and history of treatment. The mean duration of follow-up was thirty-four months in the physiotherapist-directed group and forty-eight months in the surgeon-directed group. No significant difference was found between the two groups with regard to the mean number of initial casts, the Achilles tenotomy rate, or the failure rate. Recurrence requiring additional treatment occurred in 14% of the feet in the physiotherapist-directed group and in 26% of the feet in the surgeon-directed group (p = 0.075). Additional procedures, including repeat Achilles tenotomy or a limited posterior or posteromedial release, were required in 6% of the feet in the physiotherapist-directed group and in 18% of those in the surgeon-directed group (p = 0.025). CONCLUSIONS In our institution, the Ponseti method of cast treatment of idiopathic clubfeet was as effective when it was directed by a physiotherapist as it was when it was directed by a surgeon, with fewer recurrences and a less frequent need for additional procedures in the physiotherapist-directed group. The introduction of the physiotherapist-supervised clubfoot clinic at our institution has been effective without compromising the quality of care of children with clubfoot deformity.

Does hip displacement influence health-related quality of life in children with cerebral palsy?

Abstract Objective: To evaluate the association of hip lateralisation with health-related quality of life (HRQL) in children with cerebral palsy (CP) using the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD®) questionnaire. Methods: We assessed n = 34 patients (mean age: 10.2 years, SD: 4.7 years; female: n = 16) with bilateral CP and Gross Motor Function Classification System (GMFCS) Level III–V using the CPCHILD® questionnaire. Hip lateralisation was measured by Reimer`s migration percentage (MP). Results: There was an association between both, MP and GMFCS with CPCHILD® total score. Stratified analyses did not suggest interaction of the association between MP and CPCHILD® total score by GMFCS level. After adjustment for GMFCS level, we found a significant linear decrease of CPCHILD® total score of −0.188 points by 1% increment in MP. Conclusions: There was an association between MP and HRQL, which could not be explained by the GMFCS level.

German Translation of the Caregiver Priorities and Child Health Index of Life with Disabilities Questionnaire: Test–Retest Reliability and Correlation with Gross Motor Function in Children with Cerebral Palsy

We aimed to translate the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) questionnaire into German and to evaluate its reliability and validity by studying the association between CPCHILD scores and gross motor function as measured by the gross motor function classification system (GMFCS) in children with cerebral palsy (CP). The original CPCHILD questionnaire and manual were translated and back translated. It was administered to primary caregivers of persons with CP (GMFCS levels III-V) and was completed a second time 2 weeks after the first to measure test-retest reliability (n = 17). Primary caregivers of 68 children with CP; GMFCS level III (n = 14), level IV (n = 28), and level V (n = 26) completed the questionnaire. Mean total CPCHILD scores across GMFCS levels were 67.1 ± 14.9 for GMFCS level III, 56.6 ± 11.8 for level IV, and 44.3 ± 12.9 for level V. Good correlation (r =  - 0.56) was observed between GMFCS and total scores test-retest reliability showed intraclass correlation coefficients between 0.4 and 0.9. The German CPCHILD yielded similar test-retest reliability and score distributions across the GMFCS level as the original version. The best correlations were observed for domains that are close to the functional deficits.
