The Reverse Shoulder Prosthesis for Glenohumeral Arthritis Associated With Severe Rotator Cuff Deficiency

Scapula Fractures After Reverse Total Shoulder Arthroplasty: Classification and Treatment

“…We found 22 fractures to the ipsilateral scapula among 400 RTSAs during followup for an incidence of 5.5%. This is similar to the previously reported incidences of 5.0% and 6.9% in two small series [2,9]. The 22 fractures were classified into three distinct patterns (Types I-III) that may be helpful in directing treatment.…”

“…Complications such as scapular notching, glenosphere fixation failure, and joint instability are well described. However, scapula fracture, although a known complication of RTSA, has been rarely reported [2,9]. One author reported on 60 patients treated with RTSA for deficient rotator cuffs and osteoarthritis [2].…”

“…However, scapula fracture, although a known complication of RTSA, has been rarely reported [2,9]. One author reported on 60 patients treated with RTSA for deficient rotator cuffs and osteoarthritis [2]. Three scapula fractures in two patients were identified at an average duration of followup of 33 months with an incidence of 5%.…”

Surgical Technique: The Anterosuperior Approach for Reverse Shoulder Arthroplasty

“…We excluded biomechanical studies and allowed articles analyzing surgical approach. We identified seven singlecenter studies reporting on primary RSA [2,8,12,17,18,20,21]. Seven additional studies described revision RSA [2, 5-7, 11, 17, 20].…”

What Are the Instability and Infection Rates After Reverse Shoulder Arthroplasty?

“…The two most common and major complications related to RSA are instability and infection [17]. Instability rates from 2% to 31% and infection rates from 1% to 15% have been reported [1,2,4,6,9,10,[13][14][15][16][17][18][19]. One of the largest series in the literature to date contains 199 patients from two surgeons with an instability rate of 8% and an infection rate of 4% [17].…”
