Cementless femoral fixation in total hip arthroplasty.

Cementless femoral fixation by means of bone ingrowth has been successful in total hip arthroplasty in patients with sufficient bone quality. Consistent bone ingrowth and resultant long-term success involve many factors, including surgical technique, initial mechanical stability achieved at time of implantation, stem design and material, and implant surface. One potential method for achieving faster, more consistent initial bone ingrowth is use of the osteoconductive ceramic hydroxyapatite. In addition, more stable initial fixation most likely improves long-term outcome. In this article, we review the criteria for successful cementless femoral fixation and the long-term results reported in the literature.

Long-term outcome of replantation of proximal-third amputated arm: a worthwhile endeavor.

We report a successful replantation of a proximal-third avulsed left arm in a 26-year-old female with maintenance of good functional, clinical, Short Form 36, and the Disabilities of the Arm, Shoulder, and Hand outcomes results at 10 years. An organized approach combining staged surgical reconstruction and intense hand therapy allowed for both successful replantation and outcome. There exist no clear guidelines in making the decision between replantation and revision amputation. Controversy regarding the value of upper limb replantation seems to increase with ascending levels of amputation. A case report cannot provide guidelines, but several points can be made that may be of help to hand surgeons confronting this uncommon situation. In a highly motivated patient with realistic expectation, a preoperatively intact functioning shoulder should be considered an indication for attempt at replantation. With further staged reconstruction, a helper arm can still be achieved even in an avulsion-type amputation. Current operative and perioperative aspects of microsurgical replantation and subsequent reconstruction are discussed.

Percutaneous release of A1 pulley.

We performed 100 percutaneous releases of the trigger digits in a cadaveric model using an 18-gauge needle. Successful percutaneous release was achieved for only 59 digits (59%). No neurovascular injury occurred. We found that a percutaneous trigger digit release resulted in high percentage of incomplete releases of A1 pulley, especially in the thumb, index, and little fingers.

Joint distraction may be unnecessary in ankle arthroscopy.

Ankle arthroscopy can be performed safely using a 2.7-mm arthroscope without joint distraction.

Minimally invasive technique for finger flexor pulley reconstruction.

A minimal invasive technique for finger flexor pulley is described. The technique is compared biomechanically to a "single loop" tendon graft technique using a cadaveric model.

Recurrent enchondroma protuberans: a case report.

Enchondroma protuberans is a rare benign tumor. We present a case of late recurrence of a previously reported enchondroma protuberans in the hand. This was treated successfully with curettage and calcium carbonate grafting.

Simultaneous dislocations of the carpometacarpal joints: a case report.

A case of simultaneous dislocations of the carpometacarpal joints is reported. Closed reduction and splinting produced a good result.

Giant cell tumour of the distal phalanx of the hand.

Giant cell tumour of bone in the phalanx of the hand is extremely rare. A case of giant cell tumour of distal phalanx treated with a ray amputation is presented.

Synovial chondromatosis of the distal radioulnar joint.

Synovial chondromatosis is a rare lesion in the wrist and it is extremely uncommon in the distal radioulnar joint. This case presented with wrist pain, swelling and locking secondary to synovial chondromatosis of distal radioulnar joint.
