Postoperative Pathologies of the Hand Following Shoulder Surgery

Shoulder arthroscopy and arthroplasty are increasingly common procedures used to address shoulder pathologies. This study sought to evaluate the incidence of hand-related pathologies, including carpal tunnel syndrome (CTS), cubital tunnel syndrome (CuTS), trigger finger (TF), de Quervain tenosynovitis, and Dupuytren disease following shoulder arthroscopy and arthroplasty procedures. We hypothesized that patients undergoing shoulder surgery would have a higher incidence of hand-related pathologies within 1 year of surgery compared to controls.

This was a retrospective analysis of 12,179 patients who underwent shoulder arthroscopy or arthroplasty surgery that were subsequently diagnosed with CTS, CuTS, TF, de Quervain tenosynovitis, or Dupuytren disease within 1 year after surgery. Relative risk of having associated hand pathologies following shoulder surgery was compared to controls.

In total, 10,285 patients underwent shoulder arthroscopy procedures during this period, of whom 815 (7.9%) had an associated hand pathology within 1 year from their shoulder procedure. Arthroscopic surgery was associated with an increased likelihood of having a hand pathology (RR 1.65, 95% CI 1.54-1.76), CTS (RR 1.57, 95% CI 1.42-1.73), CuTS (RR 2.25, 95% CI 1.94-2.61), TF (RR 1.76, 95% CI 1.53-2.03), and Dupuytren disease (RR 2.02, 95% CI 1.54-2.65), but was not associated with a higher likelihood of having de Quervain tenosynovitis. In total, 1,894 patients underwent shoulder arthroplasty procedures during this period, of whom 188 (9.9%) had an associated hand pathology within 1 year. Shoulder arthroplasty was associated with an increased likelihood of having a hand pathology (RR 2.04, 95% CI 1.78-2.34), CTS (RR 2.10, 95% CI 1.72-2.57), CuTS (RR 3.29, 95% CI 2.48-4.39), and TF (RR 1.99, 95% CI 1.47-2.70), but was not associated with an increased likelihood of having de Quervain tenosynovitis or Dupuytren disease.

Shoulder arthroscopy and arthroplasty procedures were associated with an increased likelihood of having a CTS, CuTS, or a TF diagnosis made within 1 year of surgery. Only shoulder arthroscopy procedures were associated with a higher likelihood of having Dupuytren disease. Neither shoulder arthroscopy nor arthroplasty procedures were associated with an increased likelihood of a diagnosis of de Quervain tenosynovitis. These associations, however, do not necessarily imply causation, and further investigation is warranted to delineate this relationship.
