Abstract:

Purpose:

To evaluate and compare patient-reported outcomes (PROs) after isolated greater tuberosity (GT) fracture fixation versus acute rotator cuff repair (RCR) at a minimum of 2 years.

Methods:

Patients who underwent isolated GT fracture fixation were compared in a 1-to-3 fashion with patients who underwent arthroscopic RCR for an acute rotator cuff tear by a single surgeon from January 2006 and to July 2018. Data were prospectively collected and retrospectively reviewed. PROs were compared pre- and postoperatively as well as between groups (American Shoulder and Elbow Surgeons [ASES], General Health Short Form-12 Physical Component [SF-12 PCS], Single Assessment Numerical Evaluation [SANE], Quick Disabilities of the Arm, Shoulder, and Hand [QuickDASH], and satisfaction). Reoperation rates were analyzed.

Results:

A total of 57 patients (14 with isolated GT fracture fixation, mean age 45.7 years; and 43 who underwent ARCR for acute tears, mean age 56.6 years) were evaluated (P = .050). ASES scores significantly improved from 39.7 to 94.1 (P = .018) in the isolated GT fracture fixation group and from 51.0 to 95.2 (P < .001) in acute RCR group. At final follow-up, mean QuickDASH scores were 8.9 and 7.9 (P = .677) and SANE scores were 91.1 and 87.3 (P = .616) for the GT and acute RCR groups, respectively. The median satisfaction was 10/10 for the GT group and 10/10 for the RCR group. Additional comparison of patients who underwent double-row repair for an acute rotator cuff tear or isolated GT fracture revealed no significant difference in outcomes (P > .404).

Conclusion:

Minimum 2-year PROs after fixation of isolated GT fractures show relatively high outcome scores whether treated by open reduction and internal fixation or arthroscopic fixation using a double-row bridging technique. The improvements in PROs are similar to those achieved with acute rotator cuff tears that were fixed arthroscopically with RCR. Further analysis of these results suggest that the functional outcomes of tendon-to-bone healing with linked, double-row rotator cuff repairs are similar to those of bone-to-bone healing as seen with GT fractures.

Level of evidence:
