Planificación preoperatoria con impresión 3D para colocación de prótesis reversa en artropatía por manguito rotador

Abstract

Rotator cuff arthropathy is an injury caused by an irreparable tear of the tendons that make up the rotator cuff, whose main treatment is mostly surgical, our objective is to present a case where planning and 3D printing was performed preoperative and anatomical guide for the placement of a reverse prosthesis in a patient with irreparable rotator cuff arthropathy. Rotator cuff arthropathy is characterized by glenohumeral osteoarthritis caused by long-standing rotator cuff tear. The treatment of this pathology is mostly surgical. We present a 67-year-old female patient with pain in the right shoulder of 18 years of evolution. On physical examination, she revealed limitation in all the arches of
movement anterior flexion 150 degrees, abduction 100 degrees, internal rotation L3, external rotation 20 degrees and positive maneuvers for the rotator cuff. Scores Constant 45/100 and ASES 38.6 / 100. The surgical time was 55 minutes from incision to synthesis, one day of postoperative hospitalization with recovery of the ranges of mobility, AF 150°, ABD 130°, ER 20°, IR L3. With these results we have concluded that preoperative planning with 3D printing of anatomical components and individualized
guides is a highly reproducible method in our environment with good functional and anatomical results.
