Christopher Nacca

About

Christopher Nacca is an orthopedic surgeon and researcher whose work centers on shoulder instability, particularly posterior glenohumeral pathology and glenoid bone loss. His major contributions have advanced the understanding of critical bone loss thresholds and optimal graft selection for posterior shoulder reconstruction. In his landmark 2018 study on “Critical Glenoid Bone Loss in Posterior Shoulder Instability” (69 citations), Nacca helped define the amount of posterior bone loss at which isolated labral repair fails to restore stability—a key clinical benchmark for surgical decision-making. He further demonstrated impact through his comparative analysis of distal tibial allograft versus scapular spinal autograft for posterior instability with bone loss (26 citations), addressing important concerns about graft morbidity and biomechanical performance. Nacca’s work has directly informed surgical practice by providing evidence-based guidelines for when and how to reconstruct the deficient posterior glenoid. His research is widely cited by shoulder surgeons and trainees seeking to improve outcomes in complex instability cases, establishing him as a thoughtful contributor to the evolving literature on glenoid bone loss management.
