Multiple Tendon Release of Lower Extremity for Cerebral Palsy Patients M.Bülent BALİOĞLU, Özgür KORKMAZ, M.Akif KAYGUSUZ MH Metİn SabancI BaltalİmanI Bone Disease Education Hospital, İstanbul, TURKEY

Purpose To evaluate the success of simultaneous multiple release of lower extremities of patients with spastic cerebral palsy (CP). Special attention was given to flexion deformity of the knee, which is the most common deformity observed in the knee. The purpose of our study was…

Purpose We compared the pre-op and post-op popliteal angles (PA) and Gross Motor Function Measurement (GMFM) of CP patients who received multiple level lower extremity lengthening to evaluate the effect of surgery and patient satisfaction.

Background Hamstrings are nearly always affected in patients with CP. Hamstrings cross two joints, the hip and the knee. Hamstrings serve as hip extensors at the hip, and at the knee they serve as knee flexors. …they…and they…

Background Hamstring spasticity can be measured with PA. Holt’s method of determining hamstring contracture. ..here is a picture of Holt’s method

Background In healthy children 4 years and older there is variability in normal PA, with a mean value of 26°. Values greater than 50° in this age range are considered abnormal.

Background A fixed knee flexion contracture may develop in severe hamstring contractures. Assessment for a fixed contracture is necessary as such a contracture may lead to complications after hamstring lengthening.

Background GMFM is a scoring system that separates CP patients into five functional levels.

Background Level 1: a child who can run, walk, and climb stairs but has mild impairments in speed and balance. Level 5: a child who depends on others for mobility, uses a wheelchair, and has no control of head or trunk.

Materials and Methods We performed multiple level lower extremity tendon lengthening for 6 CP patients with a mean age of 9.1 years (5 - 15) between 2001 and 2005. The average follow up was 57.3 months (43-76).

Materials and Methods 12 lower extremities of 6 patients (3 male, 3 female) received lengthening operations. Long term results of all patients were evaluated to control success of simultaneous multiple release of lower extremities.

Materials and Methods Hamstring, rectus femoris, iliopsoas, adductor tenotomies, tenolysis w/wo achiloplasty for both lower extremities were released simultaneously.

Materials and Methods Circular casts were applied to all patients’ lower extremities. Casts were removed 15 days postop and we began phyisiotherapy and rehabilitation with KAFO. Then…

Materials and Methods GMFM and pre versus post operative PA were used for evaluation.

Conclusion Many different methods are used to assess the surgical and conservative treatment of CP patients. Gait analysis GMFM WEE-FIM (a pediatric measure of functional independence) PODCI (Pediatric Outcomes Data Collection Instrument)

Conclusion In our study we used GMFM and PA to evaluate multiple tendon release lengthening of CP patients. GMFM scores showed that all multiple tendon releases of lower extremities in CP patients was successful.

Conclusion With regards to flexion deformity of the knee, the changes in the PA were positive. The most important factor in preventing knee flexion deformity after surgery is appropriate physical therapy and bracing.

Conclusion Both methods were practical and cost effective for postop assessment and long term evaluation and useful in terms of evaluating patient satisfaction. .
