Reversed total shoulder arthroplasty after acromioclavicular joint resection yields equivalent clinical results compared to a matched control group

Concomitant open distal clavicle excision is associated with greater improvement in range of motion without increased risk of acromial stress fracture after reverse total shoulder arthroplasty: a retrospective cohort study

“…In contrast to the Cirigliano et al 's study [17], in the present study we found RTSA-DCE to be associated with significant pre-to-postoperative improvement in ER ROM as well as flexion and IR ROM, and furthermore, the improvements in flexion and IR ROM were significantly greater than those of the RTSA group. RTSA-DCE patients had significantly lower preoperative flexion and IR ROM compared to their RTSA counterparts, which suggests that RTSA patients with clinically symptomatic ACJ OA may have inferior baseline shoulder ROM compared to RTSA patients without symptomatic ACJ OA.…”

“…Similarly, in one of the few studies conducted in the RTSA population, Cirigliano et al [17] performed a retrospective matched-cohort analysis of 39 RTSA-DCE patients matched to 39 RTSA patients and found no significant differences in postoperative flexion, abduction, ER, or IR ROM between the two groups at minimum 2-year follow-up. In addition, while both groups experienced significant pre-to-postoperative improvement in flexion and abduction ROM and no significant change in IR ROM, the RTSA-DCE group experienced a significant de-crease in ER ROM whereas the RTSA group did not.…”

“…Prior retrospective studies involving large cohorts of RTSA patients identified risk factors for postoperative ASF including older age, female sex, osteoporosis, and inflammatory arthritis, but none to date assessed whether concomitant DCE is a predictive factor for risk of ASF [6,7]. Likewise, while open DCE has been associated with common complications such as wound disruption, hematoma, and surgical site infection, neither isolated procedures nor concomitant procedures with RTSA were associated with increased rates of ASF in prior retrospective analyses [16,17]. In contrast, in a retrospective case-control study of 11 primary RTSA patients with postoperative ASFs matched to 44 controls, Townsend et al [3] noted that 20% of the control group had radiographic evidence of a prior DCE or ACJ coplaning procedure, whereas no patients in the ASF group had undergone prior ACJ surgeries.…”
