RESULTS OF REVERSE TOTAL SHOULDER ARTHROPLASTY FOR THE TREATMENT OF PROXIMAL HUMERUS FRACTURE

The International Society for Technology in Arthroplasty (ISTA), 27th Annual Congress. PART 4.



Abstract

Purpose

To evaluate the results of reverse total shoulder arthroplasty for complicated proximal humerus fractures in old ages.

Materials and Methods

We retrospectively evaluated 13 cases who underwent reverse total shoulder arthroplasty for proximal humerus fracture, fracture-dislocation and nonunions of the fractures. Mean age was 77(68–87)years old and mean follow-up period was 15.2(12–26)months. four part fractures of proximal humerus in 7 cases, fracture-dislocation in 3 cases, locked dislocation with greater tuberosity in 2 cases, nonunion with defiency of rotator cuff in 1 case were included. We evaluated mean ASES, mean UCLA, mean KSS, mean SST and mean range of motion(ROM).

Results

Postoperative mean ASES was 59(13–98.5), mean UCLA was 21(12–34), mean KSS was 62(21–94), mean SST was 5(1–11). Postoperative mean ROM was 103°(30°–135°) in forward flexion, 93°(30°–135°) in abduction, 21°(0°–45°) in external rotation and L4 level in internal rotation. The complications were not shown in any cases except for resolved heterotropic ossification. 4 cases demonstrated bony unions on greater tuberosity and 4 cases showed scapular notching on last follow-up.

Conclusions

Reverse total shoulder arthroplasty for complicated proximal humerus fracture, nonunion of the fracture, or chronic locked dislocation seems to be a good treatment options. Regardless of bony union of the greater tuberosity, reverse total shoulder arthroplasty for the complicated proximal humerus fractures had a satisfied results.
