RECONSTRUCTION WITH TUMOUR PROSTHESIS

Tumor prostheses are a useful alternative in hip revision surgery for patients with massive bone defects of the proximal femur and with a low functional demand.

The new modular designs with porous coating favor the reattachment of soft tissues and allow a customized reconstruction of the bone defect.

RECONSTRUCTIONS WITH ALLOGRAFTS AND ALLOPROSTHESIS

Reconstruction procedures may be biological or prosthetic. Biological procedures are based on vascularized diaphyseal or epiphyseal autografts or may consist of the induced membrane technique or allografts.

Reconstruction using prostheses often requires growth prostheses to limit the problems resulting from limb inequality.

In some cases, the combination of biological procedures and prostheses may be useful. Reconstruction procedures must take into account the short- and long-term functional outcome.

INTERNAL AND EXTERNAL HEMIPELVECTOMIES

This involves amputation of a section or the entire pelvis, and sometimes the entire hip and leg region.

For the recovery of patients, a hemipelvectomy prosthesis can be used, which is custom designed according to the level and area of amputation in the patient.

In some cases, a section of bone from the patient's amputated leg can even be used to replace a region of the pelvis, joining it with surgical screws.

RESECTION OF SOFT TISSUE TUMORS

Soft tissue resection is a surgical procedure in which abnormal or damaged soft tissues, such as tumors, masses, or lesions, are removed from the body.

These soft tissues may include muscles, fatty tissue, tendons, ligaments, fascia, and other connective tissues.

It is usually performed to treat and remove benign or malignant tumors found in soft tissues.

CEMENTATION IN BONE DEFECTS

Cementation is the most commonly used procedure for fixing prostheses.

Its function is to distribute and transmit loads in a more homogeneous manner, increase the contact surface between the bone and the prosthetic material, prevent stress concentrations, allow the filling of bone interstices and compensate for defects and imperfections in the surgical technique.

CRYOSURGERY WITH NITROUS OXIDE

Cryosurgery is a procedure that uses extremely cold liquid or an instrument called a cryoprobe to freeze and destroy abnormal tissue. The cryoprobe is cooled with substances such as liquid nitrogen, liquid nitrous oxide, or compressed argon gas.
