Re: Mariconda et al. Partial trapeziectomy and pyrocarbon interpositional arthroplasty for trapeziometacarpal joint osteoarthritis: Results after minimum 2 years of follow-up. J Hand Surg Eur. 2014, 39: 604-610

摘要

We read this prospective study with interest, with particular focus on the functional results of thumb opposition. The authors used the Kapandji test to demonstrate a statistically significant postoperative improvement in thumb opposition. We would like to comment on a related subgroup of patients who benefit in another way from the Ascension? PyroDisk? implant; namely those with Eaton stage li or III osteo-arthritis and an adducted trapeziometacarpal joint (TMCJ) that fails to abduct, which can be difficult to address with other techniques.
