AMPUTATION SURGERY AND PROSTHESES

Prostheses for Syme's amputation.

Whereas detailed information on Syme prostheses prior to the turn of the 20th century is not readily to be had, the catalogs issued by limb manufacturers in the early 1900's seem invariably to include a description of a prosthesis for the Syme stump. Of many different designs offered, some used articulated ankles (if space were available below the stump and socket), some used rubber feet withou...

Patient specific implants for amputation prostheses: design, manufacture and analysis.

OBJECTIVES To design, manufacture and analyze custom implants with functional gradation in macrostructure for attachment of amputation prostheses. METHODS The external shape of the implant was designed by extracting geometrical data of canine cadavers from computed tomography (CT) scans to suit the bone cavity. Three generations of implant designs were developed and were optimized with the he...

Transfemoral amputation. Biomechanics and surgery.

The technique of transfemoral amputation has evolved during the last decade whereby muscle stabilization and biomechanical principles have gained new significance. Maintenance of the femoral shaft axis close to normal can be achieved by preservation of the adductor magnus and by myodesis of the muscle to the residual femur. By following established biomechanical principles, and satisfactory sur...

Below-Knee Amputation Surgery

Throughout the history of lower-extremity amputation surgery, the relative emphasis placed on various parts of the procedure has undergone many changes as new techniques have become available and as new goals have been appreciated. At present, the amount and direction of available knowledge demand the surgeon's concern with fundamental principles. Since some of these problems must be considered...
