Patients with Dual Shoulder-Spine Disease: Does Operative Order Affect Clinical Outcomes?

OBJECTIVE

1. To analyze the effect of operative sequence (anterior cervical discectomy and fusion [ACDF] first or rotator cuff repair [RCR] first) on surgical outcomes after both procedures for patients with dual shoulder-spine injuries and 2) to determine how operative sequence affects patient-reported outcome measures (PROMs) after surgery.

METHODS

Patients >18 years of age who underwent primary ACDF and primary RCR at our institution were retrospectively identified. Only patients with overlapping symptoms before the first procedure were included. Patients were divided into 2 cohorts (ACDF first or RCR first). Patient demographics, surgical characteristics, surgical outcomes, and PROMs were compared between groups. Multivariate linear regression models were developed to determine if operative order was predictive of improvements in PROM scores at the 1-year postoperative point after the second procedure. Alpha was set at P < 0.05.

RESULTS

Of the 85 patients included, 44 patients (51.8%) underwent ACDF first, whereas 41 patients (48.2%) underwent RCR first. There were no significant differences in the rate of 90-day readmission, spine reoperations, and rotator cuff reoperations between groups (all, P > 0.05). Multivariate linear regression showed that undergoing an ACDF first was not a significant predictor of Δ Mental Component Score of the Short-Form 12 (β = -2.78; P = 0.626) and Δ Physical Component Score of the Short-Form 12 (β = 7.74; P = 0.077) at the 1-year postoperative point after the second procedure.

CONCLUSIONS

For patients with dual shoulder-spine injuries who are appropriate surgical candidates, undergoing ACDF first compared with RCR first does not result in significant differences in clinical surgical or patient-reported outcomes.
