Comparative analysis of work-related outcomes in hemiarthroplasty with concentric glenoid reaming and total shoulder...

Anatomic total shoulder arthroplasty (aTSA) has demonstrated high levels of return to work, although there are fears of glenoid component loosening with higher work demand.

A retrospective query was performed of all patients who received hemiarthroplasty with ream-and-run resurfacing (Hemi RR) between 2005 and 2014. Included patients were matched to an aTSA cohort by age, body mass index, sex, and hand dominance. Preoperative and postoperative work status, by level of duty and occupation, was collected.

Twenty-five patients receiving Hemi RR and 28 patients receiving TSA completed this questionnaire (82.8% compliance). Mean follow-up was 69.1 ± 24.8 months. In total, 100% of Hemi RR patients returned to work, and 89.3% of TSA patients returned to work (P = .091). The Hemi RR patients had higher rates of return to work for heavy-duty workers only (7 of 7 vs. 2 of 4, P = .038), although only 1 patient in the TSA group reported failure to work was due to shoulder reasons. Mean duration of return to work was 2.5 ± 4.8 months for patients receiving Hemi RR and 1.98 ± 2.6 months for those receiving TSA (P = .653).

Hemi RR had a high return to heavy-duty work, likely due to fewer surgeon-imposed restrictions. The results of this study may help manage return to work expectations after Hemi RR according to the level of duty and suggest Hemi RR is a viable option for heavy-duty laborers with end-stage glenohumeral arthritis.
