Summary
PURPOSE: Little scientific proof on the scientific and radiological consequence after stemless reverse shoulder arthroplasty (RSA) exists. The speculation of this research was that stemless RSA has an inferior consequence in comparison with RSA with stem.
METHODS: All circumstances of cuff-arthropathy fullfilling strict choice standards (choice price 18.four %) had been handled with stemless RSA between 2009 and 2013. Twenty 9 of 37 circumstances (78.four %) had been clinically and radiologically examined by an impartial observer. Twenty 4 of the 29 circumstances might be matched with 24 sufferers that underwent typical stemmed RSA at a distinct establishment based mostly on the next standards: indication (cuff-arthropathy), age (inside 5 years), gender, and time of follow-up (inside 2 years). Clincial and radiological outcomes of each teams had been in contrast.
RESULTS: After imply follow-up of 35 months (vary 24-75) no important distinction relating to fixed rating, ASES, subjective shoulder worth, ache rating, affected person satisfaction, energy, and vary of movement was detected. One case of traumatic dislocation was noticed within the stemless RSA group. Scapular notching grade 1 was detected in two circumstances of the stemless group whereas within the stemmed group 5 circumstances with grade 1 and 4 circumstances with grade 2 notching had been noticed. Common post-operative humeral element inclination (neck-shaft angle) within the stemless RSA group (134.four°) was considerably steeper than within the stemmed RSA group (155°) (p?<?zero.001). No loosening of the humeral element was noticed in each teams.
CONCLUSION: At brief to mid-term follow-up, stemless RSA doesn’t function inferior scientific or radiological outcomes in a strictly chosen affected person inhabitants.
