Summary
This summary is machine-generated.

Rotationplasty offers limb salvage for lower extremity malignant tumors. This procedure preserves function by reattaching the lower leg, using the ankle as a new knee joint, enabling prosthesis use and preventing phantom pain.

Area of Science:

  • Orthopedic Surgery
  • Surgical Oncology
  • Reconstructive Surgery

Background:

  • Malignant tumors of the lower extremity, particularly in the distal femur or proximal tibia, often necessitate aggressive surgical intervention.
  • High amputations can lead to significant functional loss and phantom limb pain.

Purpose of the Study:

  • To evaluate the efficacy of rotationplasty as a limb salvage procedure for malignant lower extremity tumors.
  • To assess the functional outcomes and patient experience with this technique.

Main Methods:

  • Resection of malignant tumors involving the knee joint with wide margins.
  • Preservation of the sciatic nerve.
  • Retransplantation of the lower leg with a 180-degree rotation, positioning the ankle at the knee joint level.

Main Results:

  • Successful limb salvage in 40 cases.
  • The ankle joint functions as a pseudo-knee, enabling prosthesis use.
  • The foot, with its sole skin, bears load effectively.
  • Absence of phantom limb pain reported by patients.

Conclusions:

  • Rotationplasty is a viable limb salvage option for lower extremity malignant tumors.
  • The procedure preserves significant function, allowing for prosthetic fitting and ambulation.
  • It offers a favorable alternative to high amputation, mitigating functional deficits and phantom pain.
