Touch® double mobility arthroplasty for trapeziometacarpal osteoarthritis: outcomes for 92 prostheses.

Trapeziometacarpal prostheses have been used in the treatment of first carpometacarpal joint osteoarthritis for many years. No studies have demonstrated statistical superiority over gold-standard trapeziectomy, but they have been proved to enable shorter convalescence, better pain relief and faster functional recovery. The aims of the present study were to report functional results in a large cohort treated with the Touch® new-generation dual mobility trapeziometacarpal prosthesis, with comparison to results in the literature. A retrospective study included 92 Touch® prostheses. Assessment comprised pre- and post-operative pain, QuickDASH score and satisfaction rate. Mean follow-up was 1.33 ± 0.4 years. Pain significantly improved after surgery. Functional QuickDASH scores did not significantly differ from those reported in the age-matched general population. Return to work was fast, at 2.6 months. Satisfaction scores were high. There were no major complications such as dislocation, fracture or loosening, but the rate of De Quervain's tenosynovitis was higher than in other studies. The Touch® prosthesis appeared to be a safe and stable implant, providing good satisfaction and very good functional scores and fast return to work and leisure activity. Considering the high rate of postoperative De Quervain's tenosynovitis, we suggest opening the first sheath of the extensors tendons while positioning the prosthesis.

Study of anatomical bases of a latero-dorsal flap of the forearm preserving the radial artery

The authors studied the dorso-lateral cutaneous branches of the radial artery in 26 forearms of fresh cadavers following injection of latex. Three toeight 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 mantain the radial artery intact
