PerLE (Peroneus Longus Evaluation): A Study Evaluating the Efficacy of Injection of Dysport in Peroneus Longus in Equinus Foot Deformity in Children With Cerebral Palsy

2016-08-05 07:08:22 | BioPortfolio


A recent publication (Boulay et al. 2012) highlighted the role of the peroneus longus (PL) muscle in equinus foot deformity in children with hemiplegia. BoNT (Dysport) injections into this muscle have not yet been described in the literature. Based on the results of a previous study, the hypothesis is: this muscle may thus constitute a new therapeutic target for botulinum toxin injections in the early management of spastic equinus in children aged 2 years or older, before the onset of fixed neuro-orthopedic deformity and the midfoot break.

The aim of this retrospective study is to describe in intramuscular BoNT (Dysport) injections into PL based on the results obtained in a cohort of children (approximately 30 subjects) with cerebral palsy (hemiplegia or diplegia) and which have been treated in the service since 2007 until July 2012.

The investigators results are based on clinical, radiological and video evaluations. For this study, data will be collected in medical folder of each children belonging to this cohort.

All children (approximately 30 subjects) with cerebral palsy (hemiplegia or diplegia) which have been treated by BoNT (Dysport) intramuscular injections into PL in the service between 2007 and July 2012 will be screened. Subjects will be selected according to the following defined inclusion and exclusion criteria.

Data will be collected retrospectively (using a specific case report form designed for the study) in medical folder of each included subject for all visit of follow-up after BoNT (Dysport) injection into PL (since the first BoNT (Dysport) injection up to 2012). Then, data will be entered in a database. After that, they will be analysed .

Medical and Biotech [MESH] Definitions

Plantar declination of the foot.

A foot deformity in which the arch of the foot is high and often the heel adducted.

Deformity in which the foot is misaligned with respect to the TALUS in the ANKLE JOINT. While mostly congenital, as in CLUBFOOT, acquired deformities are included. Acquired talipedes are often associated with other foot deformities such as SYNDACTYLY and POLYDACTYLY.

A rare central nervous system demyelinating condition affecting children and young adults. Pathologic findings include a large, sharply defined, asymmetric focus of myelin destruction that may involve an entire lobe or cerebral hemisphere. The clinical course tends to be progressive and includes dementia, cortical blindness, cortical deafness, spastic hemiplegia, and pseudobulbar palsy. Concentric sclerosis of Balo is differentiated from diffuse cerebral sclerosis of Schilder by the pathologic finding of alternating bands of destruction and preservation of myelin in concentric rings. Alpers' Syndrome refers to a heterogeneous group of diseases that feature progressive cerebral deterioration and liver disease. (From Adams et al., Principles of Neurology, 6th ed, p914; Dev Neurosci 1991;13(4-5):267-73)

A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)
