Object Large-scale natural history studies of gross motor development have shown that children with spastic cerebral palsy (CP) plateau during childhood and actually decline through adolescence. Selective dorsal rhizotomy (SDR) is a well-recognized treatment for spastic CP, but little is known about long-term outcomes of this treatment. The purpose of this study was to assess the durability of functional outcomes in a large number of patients through adolescence and into early adulthood using standardized assessment tools. Methods The authors analyzed long-term follow-up data in children who had been evaluated by a multidisciplinary team preoperatively and at 1, 5, 10, and 15 years after SDR. These evaluations included quantitative, standardized assessments of lower-limb tone (Ashworth Scale), Gross Motor Function Measure (GMFM), and performance of activities of daily living (ADLs) by the Pediatric Evaluation of Disability Inventory in children who had been stratified by motor severity using the Gross Motor Function Classification System (GMFCS). In addition, group-based trajectory modeling (GBTM) was used to identify any heterogeneity of response to SDR among these treated children, and to find which pretreatment variables might be associated with this heterogeneity. Finally, a chart review of adjunct orthopedic procedures required by these children following SDR was performed. Results Of 102 patients who underwent preoperative evaluations, 97, 62, 57, and 14 patients completed postoperative assessments at 1, 5, 10, and 15 years, respectively. After SDR, through adolescence and into early adulthood, statistically significant durable improvements in lower-limb muscle tone, gross motor function, and performance of ADLs were found. When stratified by the GMFCS, long-lasting improvements for GMFCS Groups I, II, and III were found. The GBTM revealed 4 groups of patients who responded differently to SDR. This group assignment was associated with distribution of spasticity (diplegia was associated with better outcomes than triplegia or quadriplegia) and degree of hip adductor spasticity (Ashworth score < 3 was associated with better outcomes than a score of 3), but not with age, sex, degree of ankle plantar flexion spasticity, or degree of hamstring spasticity. In a sample of 88 patients who had complete records of orthopedic procedures and botulinum toxin (Botox) injections, 52 (59.1%) underwent SDR alone, 11 (12.5%) received only Botox injections in addition to SDR, while 25 patients (28.4%) needed further lower-extremity orthopedic surgery after SDR. Conclusions In the majority of patients, the benefits of SDR are durable through adolescence and into early adulthood. These benefits include improved muscle tone, gross motor function, and performance of ADLs, as well as a decreased need for adjunct orthopedic procedures or Botox injections. The children most likely to display these long-term benefits are those in GMFCS Groups I, II, and III, with spastic diplegia, less hip adductor spasticity, and preoperative GMFM scores greater than 60.

Purpose To examine the functional outcomes of children with osteogenesis imperfecta (OI) following initial FassierDuval (FD) rodding to the femur at 1 year, and to determine which factors are associated with change in gross motor function, ambulation, and functional performance. Methods Approval from our Institutional Review Board was obtained. A retrospective chart review identified 60 children (28 males, 32 females) with OI who underwent initial FD femoral rodding (101 rods) and who were receiving bisphosphonates. The mean age of the children was 3 years, 11 months at the initial femoral FD rodding. Two had type I OI, 30 type III, 27 type IV, and one type VI. The maximum length of follow-up was 4 years. Telescoping FD rods were used for the femurs, with surgeries performed one leg at a time, with a 1-week interval. The active range of motion (AROM) of the hips and knees in flexion was measured 4-5 weeks post-initial rodding. Outcomes on the Gillette Functional Assessment Questionnaire (FAQ) Ambulation Scale, the Gross Motor Function Measure (GMFM), and the Pediatric Evaluation of Disability Inventory (PEDI) were compared pre-operatively and at 1 year post-surgery using t-tests and multivariate linear regression. Results Pre-operatively, the mean FAQ score was 2.0, and this increased to 5.8 at 1 year post-surgery. Statistically significant improvements (P B 0.05) were found on the FAQ, crawling, standing, walking and running, and total domains of the GMFM, and PEDI mobility and self-care from baseline to 1 year. The results from the multivariate linear regression indicate that older age (P = 0.0045) and higher weight (P = 0.0164) are significantly associated with lower scores in the self-care domain of the PEDI, and that OI type III compared to type IV is significantly associated (P = 0.0457) with greater improvement on the crawling domain of the GMFM. Higher weight was also associated (P = 0.0289) with lower scores in the standing domain of the GMFM, as well as with the total GMFM score (P = 0.0398). Conclusions Our findings indicate that initial FD femoral rodding resulted in benefits in ambulation, gross motor function, self-care, and mobility for children with OI beyond physiological expectations due to developmental growth. FD rodding is a procedure which can improve the overall mobility in children with OI with significant femoral deformities.

BackgroundAchieving a successful transition from pediatric to adult care for young adults with special needs, especially rare genetic diseases such as osteogenesis imperfecta (OI), is a prominent issue in healthcare research. This transition represents a challenge for patients with OI, their families, clinicians and healthcare managers because of the complex nature of the process and the lack of evaluation of existing transition programs. We evaluated a transition program for adolescents and young adults with OI from a pediatric orthopedic hospital to adult care.MethodsData were collected by interview, observation, and document review from April 2013 to October 2013. Participants included six patients with OI, four parents, and 15 staff, including administrators, coordinators, social workers, nurses, pediatricians, surgeons, occupational therapists and physiotherapists. A SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis was performed.ResultsThe strengths of the transition program included a solid theoretical approach based on a partnership with parents, and a comprehensive transition model based on fostering independent living and professional integration. The program’s main weaknesses were the successive organizational changes and discontinuation of certain transition activities, and the potential conflict between the transition program and participation in research protocols. Further opportunities include the implementation of a multi-site transition model with cross-site personnel and user evaluations, with the inclusion of second-generation patients. Dissatisfaction reported by some care-team members at the adult care hospital could threaten collaboration among institutions involved in the transition process, whereas dissatisfaction of some former patients may reduce their perceptions of quality of care received during the transition.ConclusionsThis study confirmed that a “one-size-fits-all” transition model for patients with OI would be inappropriate across, or even within institutions. Opportunities should be seized to create tailored, theoretically-sound transition programs that reflect patient preferences, especially those of young adults with complex and chronic health conditions. Alignment with other organizational activities should be considered, and ongoing evaluation of transition programming may be required. This SWOT analysis and utilization-focused evaluation has led to a comprehensive new project to improve the transition program for patients with OI and other conditions requiring special follow-up.
