Effects of Prior Cervical Fusion on Patient Outcomes After Shoulder Arthroplasty

BackgroundThe coexistence of cervical disease and shoulder pathology is not uncommon. The purpose of this study is to evaluate the early complication rates and outcomes after shoulder arthroplasty in patients with prior cervical arthrodesis.MethodsA retrospective analysis was performed on a prospectively collected cohort at a single institution. Shoulder arthroplasty (TSA or RTSA) patients with prior cervical fusion (cervical arthrodesis-shoulder arthroplasty [CASA]) were identified and age-matched to controls without cervical fusion from 2012 to 2015. Early (<90-day) complications, visual analog scale (VAS) pain scores, and hospital length of stays were analyzed. Active shoulder range of motion (ROM) and American Shoulder and Elbow Surgeon (ASES) scores preoperatively, 6-week, 6-month, and 1-year postoperatively were compared.ResultsSeventeen CASA patients were matched to 34 controls. Patients were similar in gender, American Society of Anesthesiologist score, body mass index, opioid use, and arthroplast...
