VALBUENA, Sebastián E  and  LE VIET, Dominique. Uncinate process of hamate excision in nonunion. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2010, vol.75, n.4, pp.351-356. ISSN 1852-7434.

Background: The hook of the hamate fracture is rare. The diagnosis is generally late and nonunion is frequent. Methods: Between 1988 and 2005, 14 patients with nonunion of the hook of the hamate were treated surgically with hook excision. We analyzed the following: time to diagnosis, images, and clinical presentation. Results were evaluated with the Mayo Modified Wrist Score, while the Student's t-test was used for the statistical analysis. Results: The time to diagnosis was 9 months in average (range 3-204). Eight patients had very good results (57.2%), 4 good (28.6%), 1 fair (7.1%) and 1 poor result (7.1%). From 11 athletes, 10 returned to the same level at the final follow up. No major complications were found. Conclusions: The excision of the hook of the hamate is an excellent option in case of non-union, allowing a quick return to daily activities.
