Ultra-short stems with proximal load transfer: Clinical and radiographic results at five-year follow-up.

Bone stock preservation is crucial when performing THR in young patients. Following this philosophy, an original ultra-short custom-made implant with extensive proximal load transfer was developed. It presents three very innovative features: absence of the diaphyseal portion of the stem, a well defined lateral flare with load transfer on the lateral column of the femur and a very high femoral neck cut.

Shoulder prosthesis in reconstruction of the scapulohumeral girdle after wide resection to treat malignant neoformation of the proximal humerus.

Progress in preoperative chemotherapy and radiation therapy, both intra- and postoperative, has in time allowed for an increase in indications for shoulder implant surgery in malignant tumors, thus drastically reducing the number of amputations. The use of prostheses, particularly those of the more recent generation, respond to the needs to overcome the limits of loss of movement, as long as good anatomical reconstruction of the soft tissues, the premise for good functional and cosmetic recovery, is also possible. The current tendency is that of using modular shoulder prostheses that provide a wide variety of sizes.
