Long-term results of the Aptis total distal radioulnar joint prosthesis after previous failed surgical procedures.

We present a prospective study with the results of ten Aptis total distal radioulnar joint replacements in patients who had one to five previous operations. The mean postoperative follow-up was 9.7 years (range 3-14.

Results of the total wrist arthrodesis with contoured plate in a series of 41 wrists with median follow-up of 6 years.

We present a comparative analysis between the pre and postoperative status of 41 wrists subjected to total arthrodesis with contoured plate, analysing the functional and radiological results, subjective satisfaction and return to work. The indications for surgery were post-traumatic arthritis (56.1%), Kien- böck's disease (17.

Total wrist fusion versus total wrist prosthesis: a comparative study.

We present a comparative study of 41 total wrist fusions (TWFs) with contoured plate and 22 total wrist prostheses using the Universal 2™ model, with a mean follow-up of 6 years for the fusion and 6.5 years for the prosthesis. We evaluated grip strength, pain according to the visual analogue scale, functional results using the Quick Disabilities of the Arm, Shoulder and Hand and the Patient-Rated Wrist Evaluation, degree of satisfaction and complications, with no significant differences being observed in any of these variables.

Postoperative assessment and management of metallosis and periprosthetic osteolysis in patients treated with metal-on-polyethylene total wrist prostheses.

We analysed the relationship between serum metal ions, radiological periprosthetic osteolysis and the clinical features in a series of 25 patients treated with fourth-generation metal-on-polyethylene total wrist prostheses. The mean implant follow-up was 7 years. Our results show that titanium was the main elevated serum metal ion in patients with the prostheses that we used; elevated serum cobalt or chromium values were infrequent.

Aggressive digital papillary adenocarcinoma of the hand: an unsuspected malignant tumour of the sweat glands.

We report a case of a man with a tumour of the palm that grew slowly for five years, being repeatedly diagnosed as a synovial cyst. Histopathological diagnosis showed an aggressive digital papillary adenocarcinoma. Thirty-eight months postoperatively there was neither recurrence nor signs of metastases.

Skin coverage in frostbite injuries: experimental study.

Objective: Dermal grafting after secondary wound healing constitutes the mainstay of management in cold injury tissue defects, displacing the use of local flaps. We present an experimental study in which the following treatments for frostbite defects are compared: guided wound healing, partial-thickness skin grafts and cutaneous flaps, which by definition posses an independent vascular supply.

Material And Methods: A dorsal defect in the rabbit leg was created using a cold injury model.
