Reverse Total Shoulder Arthroplasty With or Without Partial Coracoidectomy: Evaluation of Functional Internal Rotation (I-CORE)

May 28, 2026 updated by: Clinique Générale dAnnecy

Reverse Total Shoulder Arthroplasty With or Without Partial Coracoidectomy: a Randomized Controlled Trial Evaluating Functional Internal Rotation

This project aims to conduct a randomized controlled trial comparing the functional outcomes and complications of standard reverse total shoulder arthroplasty and reverse total shoulder arthroplasty combined with partial coracoidectomy. The study will assess functional internal rotation at 12 months post-surgery, as measured by the ADLIR (Activities of Daily Living requiring Internal Rotation) score.

Description

Inclusion Criteria:

- Adults undergoing reverse total shoulder arthroplasty (rTSA), including primary procedures or fracture repair. Indications may include arthropathy due to a rotator cuff tear, primary glenohumeral osteoarthritis with an irreparable rotator cuff tear, or post-traumatic arthritis.

Exclusion Criteria:

  • Patients with a history of coracoid fractures or who have previously undergone surgery involving the coracoid process.
  • Patients undergoing latissimus dorsi transfers
  • Presence of an active infection, inflammatory arthritis, or a tumor affecting the shoulder region.
  • Patients with pre-existing neuromuscular disorders affecting shoulder function
  • Patients who are unwilling or unable to participate in the trial or complete follow-up assessments
  • Patients deprived of their liberty by judicial or administrative order, in pretrial detention, or under guardianship, conservatorship, or judicial protection.
  • Pregnant women, women in labor, or breastfeeding women
  • Patients receiving psychiatric care
  • Patients not enrolled in a social security program

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assessment of functional internal rotation, as measured by the change in the ADLIR (Activities of Daily Living requiring Internal Rotation) score
Time Frame: 12 months after surgery
A maximum score of 100 indicates that the patient experiences no discomfort in daily life due to limited internal rotation. A minimum score of 14 indicates severe functional impairment due to limited internal rotation.
12 months after surgery
