The aim of this study was to evaluate the usefulness of computer tomography (CT) in preoperative planning and outcome assessment in operative management of idiopathic scoliosis with severe internal vertebral deformity.

Unlabelled: Authors present the effect of intramuscular injections of botulinum toxin A (BTX-A) in the treatment of hip instability in children with spastic cerebral palsy.

Material And Method: The sixty-seven non walking children (110 hips) with quadriplegia and hip instability (MP > 33% or increase of MP > 20% in the second follow-up after 12 months) were evaluated. The mean age of patients in the beginning of study was 3 years and 8 months (SD = 2 years).

Unlabelled: The hip joint dislocation is one of the most serious complications associated with severe type of spastic cerebral palsy in children. The natural history of this secondary problem is poorly defined: how often and why the dislocated hip joint is going to be painful. The aim of our study was to specify prevalence of hip pain in the quadriplegic spastic type of cerebral palsy children with dislocated one or two hip joints.
