Video-assisted gastrocnemius-soleus and hamstring lengthening in cerebral palsy patients.

The aim of the study was to present the results of video-assisted fractional lengthening of the triceps surae muscle and the hamstrings in children with spastic cerebral palsy. In the period from September 2003 to December 2004, triceps surae muscle contractures were treated in 35 lower extremities (22 patients) and hamstring lengthening was performed in 12 knees (eight patients). The patients were between 4 and 10 years of age. Lengthening of the gastrocnemius-soleus was sufficient for achieving 10 degrees dorsiflexion of the foot in 31 of the 35 extremities. The short-term follow-up, at least 1 year after operation, did not reveal any complications. The hamstring lengthening resulted in full correction in nine knees; one endoscopic procedure required conversion to open surgery owing to bleeding. In one case, incomplete sciatic nerve palsy developed. Video-assisted gastrocnemius-soleus recession as well as video-assisted lengthening of the hamstrings proved to be fully efficient in the group reported here.
