RESUMO
AIM: Mid-term result documentation of ceramic-on-ceramic cementless total hip replacement. METHOD: From November 1998 to December 2005, 356 patients were submitted to 419 total hip arthroplasties of the hip with a cementless, ceramic-ceramic Bicontact/Plasmacup type of prosthesis. Patients were controlled in a consecutive prospective study. RESULTS: The average age of the patient group is 47.9 years, with an average follow-up of 48 months. There was no case with release of osteolysis of the acetabular or femoral components. There was one ceramic head fracture in an obese patient. Articular wear was negligible and could not be measured radiographically. CONCLUSION: The ceramic-ceramic Bicontact hip joint replacement presents a low complication rate in young patients, with very low wear.

The Madelung deformity can result in pain and decreased function of the wrist and hand. None of the surgical techniques available has been shown consistently to improve grip strength, range of movement or relieve pain. In this prospective study we have treated 18 patients with the Madelung deformity (25 wrists) by wedge subtraction osteotomy of the radius and shortening of the ulna. Our results show statistically significant improvement in grip strength and range of movement of the wrist and forearm. Pain improved in 80% of the patients and 88% were satisfied with the appearance. One patient had a wound infection and another developed reflex sympathetic dystrophy. Two had some recurrence due to continued growth of the ulna and it is recommended that the procedure be delayed until skeletal maturity, or else combined with epiphysiodesis of the ulna.

The authors studied the dorso-lateral cutaneous branches of the radial artery in 26 forearms of fresh cadavers following injection of latex. Three to eight branches were identified, with frequent anastomoses. Extensive venous drainage was also observed. One to three cutaneous branches arose within a 3-cm region close to the radial styloid precess. This provides a basis for an island flap supplied by these branches and thus, it is possible to maintain the radial artery intact.

Based on results of a prospective study of 200 patients with "mallet finger", the author establishes criteria to divide the injuries into recent and late. In view of the radiologic and anatomic findings as well as the extent of "falla" of the distal phalanx, a classification that allows prognosis and type of most adequate treatment for each case, is proposed.
