Novel Descriptions of the Radial Osteotomy in Kienböck's Disease: A Systematic Review.
Journal of hand surgery global online. 2023 July
PURPOSE: Kienböck's disease consists of intrinsic and extrinsic characteristics that coalesce into a pathology with multifactorial etiology. Mechanical, morphological, and vascular factors have been identified as contributory. Radial osteotomy is one of the most commonly used surgical treatment for late-stage Kienböck's disease. Despite its frequent use and reported value, the specifics of radial osteotomy have not been described in aggregate. Our objective was to review the recent literature for descriptions of the radial osteotomy techniques used for treatment of Kienböck's disease.
METHODS: The inclusion criteria for the systematic review were as follows: (1) patients aged >18 years, (2) a publication date no older than 2012, and (3) a complete description of the distal radius osteotomy technique, including verbiage that specified numeric dimensions of bony resection or verbiage that detailed a goal in terms of a radiographic parameter that would guide the bony resection.
RESULTS: The studies were grouped according to the stated description of radial osteotomy. This process yielded the following three main groups: (1) studies that used radial shortening, (2) studies that used lateral closing wedge osteotomy or combined lateral closing wedge with radial shortening, and (3) novel osteotomy descriptions.
CONCLUSIONS: The Kienböck's disease literature predominantly describes an osteotomy to shorten the radius by 2-3 mm. In some studies, the degree of radial shortening corresponded to the value necessary to achieve near-neutral ulnar variance. The common goal in using lateral closing wedge osteotomy was to achieve a radial inclination of 5° to 15°. Unique wedge resections, some with multiplanar corrections, have been recently described with each purporting specific advantages.
CLINICAL RELEVANCE: Our findings support the premise of mechanical and biologic efficacy for radial osteotomy, with satisfactory results being reported across a wide spectrum of osteotomy techniques.
