Van Nes rotationplasty with segmental limb resection.

Segmental limb resection is becoming a practical alternative to limb ablation in tumor surgery. The addition of Van Nes rotationplasty to provide a pseudo knee joint has been found to be a practical, functional addition facilitating prosthesis use. This procedure has now been used successfully in 21 children with malignant neoplasms, with few complications. The surgical technique, as outlined, produces significantly improved functional results over an above-knee amputation or hip disarticulation.
