[Shoulder arthroplasty in Mexico. Ten-year experience, multicenter study]

degenerative shoulder diseases have an estimated prevalence between 16 and 25% in the population over 65 years of age. Mexico lacks a system to document and analyze shoulder arthroplasty procedures. This study aimed to identify the clinical profile of patients undergoing shoulder arthroplasty in Mexico.

observational, descriptive, and multicenter study conducted between 2014 and 2024. Clinical and demographic characteristics were collected, including comorbidities, surgical indication, Constant functional score, type of arthroplasty performed, type of prosthesis used, and average cost.

a total of 516 patients were included; 353 (68.41%) were female. The mean age was 70.09 ± 9.5 years. The right shoulder was affected in 321 (62.2%) cases, and right-hand dominance was present in 485 (93.9%) patients. The most common comorbidity was arterial hypertension (266 patients, 39.45%). The most frequent indication was rotator cuff tear arthropathy (208 patients, 40.31%). The Constant score improved by 46.54 points. The most commonly used arthroplasty was reverse in-lay (339 cases, 65.69%). The average cost per prosthesis was $170,000.00 MXN.

in our country, the typical candidate for shoulder arthroplasty is a female patient between 60 and 80 years of age, with a diagnosis of rotator cuff tear arthropathy or osteoarthritis causing significant functional limitation of the affected limb.
