KOL-Index: 27 Purpose: Surgery is often required for fixed knee flexion contractures in patients with neuromuscular conditions. Anterior distal femoral hemiepiphysiodesis (ADFH) is an alternative to distal femoral extension osteotomy (DFEO) in skeletally immature patients. ADFH is typically not accompanied by patellar tendon shortening surgery (PTS). Our purpose was to compare ADFH alone versus ADFH with ...

KOL-Index: 25 Cerebral palsy (CP) is defined as motor impairment that limits activity, and is attributed to non-progressive disturbances during brain development in fetuses or infants. The motor disorders of CP are frequently accompanied by impaired cognition, communication, and sensory perception, behavioural abnormalities, seizure disorders, or a combination of these features. CP is thought to affect ...

KOL-Index: 18 BACKGROUND: Medial calcaneal sliding (CS) osteotomy and lateral column lengthening (LCL) are often performed to relieve pain and improve transverse plane alignment and gait stability for children with cerebral palsy (CP) and valgus foot deformities. The purpose of this study was to examine the effectiveness of these procedures in this population. METHODS: Retrospective medical record review ...

KOL-Index: 17 BACKGROUND: Shoulder ROM and function of the shoulder are difficult to evaluate in young children. There has been no determination of the age at which children can comply with the current assessment tools in use, but doing so would be important, because it gives us more accurate insight into the development and assessment of shoulder functional ROM in young children. QUESTIONS/PURPOSES: We ...

KOL-Index: 16 BACKGROUND: Children with cerebral palsy (CP) have decreased strength, low bone mass, and an increased propensity to fracture. High-frequency, low-magnitude vibration might provide a noninvasive, nonpharmacologic, home-based treatment for these musculoskeletal deficits. The purpose of this study was to examine the effects of this intervention on bone and muscle in children with CP. METHODS: ...

KOL-Index: 15 Introduction The study aims were to assess impact of an intensive camp-based intervention using a hybrid model of modified constraint induced movement therapy with bimanual therapy in children with upper extremity impairment, and to see if improvements persisted over time. Method Twenty subjects participated. Eight subjects attended camp 2 years in a row, and 12 subjects attended camp only ...

KOL-Index: 13 INTRODUCTION: The study purpose was to determine the safety/efficacy of a split anterior tibialis tendon transfer (SPLATT) to the peroneus tertius or brevis in children with static encephalopathy and varus feet. METHODS: A retrospective review of short- and long-term complications, change in ankle range of motion, strength, and gait kinematics. Predictors of postoperative varus or valgus ...

KOL-Index: 13 BACKGROUND: Hamstring lengthening surgery (HSL) is often performed to correct crouch gait in patients with cerebral palsy (CP). However, crouch can recur over time, and repeat HSL may be ineffective. One possible reason is that the hamstrings in repeat HSL patients are neither short nor lengthening slowly and would therefore not benefit from HSL. RESEARCH QUESTION: This study aimed to ...
