Arthroscopic Bone Grafting and Arthrodesis of Partial Lunotriquetral Coalition

Background  Lunotriquetal coalition is the most common carpal coalition that can be symptomatic if trauma disrupts the syndesmosis or synchondrosis or if degenerative changes develop between the abnormal articulating surfaces. Case Description  A 15-year-old boy presented with a symptomatic lunotriquetral coalition after a fall 2 years prior. Following appropriate investigation, he was managed via arthroscopic debridement, bone grafting, and lunotriquetral arthrodesis. Literature Review  The majority of symptomatic lunotriquetral coalitions have been managed with open arthrodesis. There is only one prior report of arthroscopic arthrodesis of this articulation that did not utilize bone graft. Relevance  This report details the procedure to allow arthroscopic lunotriquetral arthrodesis with bone grafting, conveying osteogenic properties, and encouraging incorporation at the fusion site while maintaining the dorsal ligaments.
