However, two cases with post-operative scapular spine fractures were reported to have a poor outcome, with pain and poor motion. Different systems may have different modes of disassembly, and it remains to be seen whether this complication can be completely eliminated. Eccentric glenospheres with an inferior offset and glenoid components with increased lateral offset (bony or metal) can reduce the rate of notching. Complications after reverse shoulder arthroplasty (see Table 1) continue to be higher in primary and revision shoulder surgery when compared to total shoulder arthroplasty.

As the concept and design of the reverse shoulder is evolving, the rate and type of complication may change over time. After 1.5 years the patient was diagnosed with a periprosthetic joint infection and underwent a two-stage revision arthroplasty. When instability happens, it is usually in the first six months, and of those, half occur in the first three months.26 Conservative management can be successful in almost half of patients, and shoulders that remain stable after closed reduction have a similar outcome in terms of pain and motion.

Of note, repair of the subscapularis was associated with a greater improvement in range of motion in internal rotation when compared to patients without repair in a study by Wall et al.13 Trappey et al further analysed 284 arthroplasties and found 11 cases of instability in 212 primary cases (5.2%) and six cases in 72 revision arthroplasty cases (8.3%), and found a higher risk of dislocation when the subscapularis was irreparable and in fracture sequelae.30 Fracture sequelae, tumour surgery and instability arthropathy have shown the greatest incidence of instability.5,6,30 The primary diagnosis may affect the status of the subscapularis, the rate of impingement, and may increase the difficulty of assessing the correct height, version and adequate soft tissue tension, all of which can affect the stability of the arthroplasty.

Guery et al have shown a 91% implant survival rate at ten years, although it should be emphasised that most of the patients included in this study were elderly with low functional demands, and the primary diagnosis was rotator cuff tear arthropathy (Fig. Fig. 5 This figure shows the case of a patient that four months after uneventful RSA for rotator cuff arthropathy (left column) suffered a fall with acute onset of pain on the top of his right shoulder. They may also be under-reported due to the fact that spontaneous recovery happens in many cases.57 The most common nerve dysfunction after RSA involves the axillary nerve, although post-operative radial, ulnar, and musculocutaneous nerve palsies have been reported as well.58 Partial recovery of the axillary nerve may affect the clinical outcome, as it can affect deltoid strength.46 The suprascapular nerve and artery may be at risk at the spinoglenoid notch when drilling the posterior screw.
It can be easily observed that qB/I, r· At very low orbital altitudes (≲450 km) the aerodynamic forces can become major attitude disturbances. The rate of complications is influenced by many factors. Factors that may explain the higher infection rate include increased implant surface, a larger dead space, patient factors and the complexity of some of the indications.16 The reported incidence in the literature varies from 1% to 15%. In a meta-analysis, Zumstein et al reported a mean infection rate of 3.8% in a systematic review including primary and revision RSA, with a higher rate in revision surgery.14 For non-reverse arthroplasty, lower rates of infection have been reported.
