To determine if uncemented implants would provide similar outcomes while avoiding the complications associated with cement in the treatment of elderly patients with proximal humerus fractures (PHFs) with primary reverse total shoulder arthroplasty (RTSA).
A single Level I trauma center
Patients/Participants: A prospectively-obtained cohort of 30 patients who underwent uncemented RTSA as initial treatment for a comminuted PHF: 4 male, 26 female; average age 71 ± 11 years.
Uncemented reverse total shoulder arthroplasty.
1) Radiographic analysis, 2) Postoperative clinical range of motion (ROM), and 3) Functional outcome scores: the American Shoulder and Elbow Surgeons Shoulder (ASES) score and the Simple Shoulder Test (SST) score.
Radiographic analysis showed 97% achieved stable humeral stem fixation and 70% had healing of the tuberosities in anatomic position. Average ROM was 130 ± 31° of forward flexion, 32 ± 18° of external rotation, and internal rotation to the mid-lumbar spine. Average ASES score was 82.0 ± 13.5 (with an average pain rating of 0.8 ± 1.3), and average SST score was 69.4 ± 19.1%.
Our data show that treatment of comminuted PHFs in elderly patients with uncemented RTSA can consistently produce good clinical outcomes with a low rate of complications and suggest that cement may not be necessary for RTSA in the trauma setting.
