In the period of 1976-1987 there were in total 181 patients operated on with the diagnosis of infantile cerebral palsy at the Orthopaedic Clinic of the Faculty of Pediatrics of Charles University in Prague-Motol. 412 operations were performed in total in these patients. The indication was mainly the improvement of the statics and gait, therefore operations on lower extremities prevailed. Within the preoperative preparation it is essential to precisely classify the type of affection of the patient from the neurological viewpoint and mainly estimate the future physical and psychical abilities of the child which is of substantial importance in the postoperative treatment. The surgical solution is always individual and respects the specificity which need not be symmetric on both extremities. Therefore the range of orthopaedic operations is wide. The surgeon has to treat the equinus position of the foot, the valgus position, flexion contractures of knees, adduction position in hip joints. In case it is necessary to operate the affection of the entire lower extremity the specialists at the above mentioned Orthopaedic Clinic prefer a single solution to the stepwise one. Recently the surgical treatment of patients suffering from spasm has achieved a certain progress. Substantial is the contribution for patients who on the basis of the operation regain the ability to walk. Therefore the authors emphasize the importance of the cooperation of the neurologist and the rehabilitation worker with the orthopaedic surgeon when considering comprehensive therapeutical possibilities.
