ABSTRACT
Introduction: Elbow arthrosis is caused by this extremity's overuse or by a previous or repetitive trauma. The American Academy of Orthopedic Surgeons states that the elbow's functional range for daily activities without limitations is of 100°. Articular replacement has one of the highest revision indexes. Due to this fact, it is very important to offer alternatives for treatment. The Outerbridge-Kashiwagi Method (OKM) is a simple procedure that enables liberation and decompression with osteophyte resection produced in olecranon, coronoid and respective fossa. The objective of this study is to demonstrate the efficacy of the OKM as an alternative treatment for total articular replacement in elbow arthrosis.Material and Methods: We included 15 patients who underwent OKM. Initial evaluation and continuous follow-up for 12 months were done using two functional scores: Mayo Elbow Score (MES) and Oxford.
Results: The median age was 58.6 years in preoperative evaluations, flexion range 86.9° (70-104°), extension range 11.6° (0-30°), pronation 49° (40- 54°), supination 56° (46-70°), mean MES of 33.6 points (20-45), and initial Oxford 26.3 points (24-29). During our follow-up, MES 12 weeks after surgery was 80.6 points, with an average of 70-90 points compared to the preoperative values, with a statistical significance of p=0.001 (CI 95% from 52-41). 24 weeks after surgery we recorded a MES of 85 points (80-90), p=0.004 (CI 95% 1-7).
Discussion: The OKM notably remarkably improved the elbow's functionality, pain and movement. This was objectively recorded by the functionality scores with statistical significance.
