Reverse total shoulders in patients under 65 years of age, 1 in 7 had reoperations

Complications and implant survivorship following primary reverse total shoulder arthroplasty in patients younger than 65 years: a systematic review

These authors conducted a systematic review of the literature regarding the existing evidence on primary reverse shoulder arthroplasty (RTSA) in patients younger than 65 years. The indications for RTSA were cuff tear arthropathy (39%), massive cuff tear (23%), glenohumeral arthritis (11%), fracture (4%), rheumatoid arthritis (2%).

Data was extracted from 7 studies with a total of 286 shoulders in patients aged 58.4 years (mean age range, 48.9-60.4 years) with a mean follow-up period of 4.7 years (mean follow-up range, 3.0-7.8 years).

The gains in comfort and function were statistically significant, but modest:

In four studies the SST improved from 2.0 to 6.7 
In three studies, the ASES score improved from 31.3 to 68.3.
In three studies the relative Constant score improved from 33.5 to 71.9.
In two studies the SSV improved from 21.2 to 70.5
In one study the UCLA score improved from 12.6 to 27.29 
In two studies visual analog scale score for pain improved from 7.3 to 2.2.

The overall rate of complications was 18.6%; reoperations, 14.4%; and revisions, 11.2%. The most common adverse events were instability and infection.

The overall rate of scapular notching was 22.7% at final follow-up.

Comment: These results prompt us to consider carefully the more conservative options 

for treatment of cuff tear arthropathy without pseudoparalysis (such as the cuff tear arthropathy arthroplasty, see this link), 

for the treatment of massive cuff tears without pseudoparalysis (such as the smooth and move procedure, see this link), and

for the treatment of glenohumeral arthritis (such as an anatomic total shoulder arthroplasty, see this link).
