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

Area of Science:

• Orthopedics
• Arthroplasty Surgery
• Public Health

Background:

• Degenerative shoulder diseases affect 16-25% of individuals over 65.
• Mexico lacks a centralized system for documenting shoulder arthroplasty procedures.
• This study addresses the need to understand patient profiles for shoulder arthroplasty in Mexico.

Purpose of the Study:

• To identify the clinical and demographic profile of patients undergoing shoulder arthroplasty in Mexico.
• To analyze comorbidities, surgical indications, and functional outcomes.
• To document the types of prostheses used and associated costs.

Main Methods:

• An observational, descriptive, multicenter study was conducted from 2014 to 2024.
• Data collected included patient demographics, comorbidities, surgical indications, Constant functional scores, arthroplasty type, prosthesis type, and cost.
• A total of 516 patients were included in the analysis.

Main Results:

• The typical patient was female (68.41%), with a mean age of 70.09 years.
• Rotator cuff tear arthropathy (40.31%) was the most frequent indication, and arterial hypertension was the most common comorbidity (39.45%).
• Reverse in-lay arthroplasty was most common (65.69%), with an average cost of $170,000.00 MXN. The Constant score improved by 46.54 points.

Conclusions:

• The profile of a typical shoulder arthroplasty candidate in Mexico is a female aged 60-80.
• Common indications include rotator cuff tear arthropathy and osteoarthritis leading to functional limitation.
• Shoulder arthroplasty demonstrates significant functional improvement in the Mexican population studied.
