Background: The earliest distal humeral hemiarthroplasty (or elbow hemiarthroplasty [EHA]) implants, which date back to the late 1940s, were performed in patients with severe elbow joint injuries as an alternative to arthrodesis. After some clinical reports and case studies with a short follow-up, published in the 1990s, a new "anatomically convertible" EHA model was introduced in 2005 and became a common surgical option to treat complex elbow fractures and their sequelae. We describe the mid- and long-term outcomes of EHA performed to treat acute intra-articular fractures or their sequelae., Methods: From 2006 to 2017, 51 patients underwent EHA for acute intra-articular fractures or their sequelae. A total number of 41 patients (80.5% female) with a minimum follow-up of 2 years, 24 with acute lesions and 17 with sequelae, were identified retrospectively. Clinical evaluation was according to the Disabilities of the Arm, Shoulder, and Hand (DASH) score (subjective), and the Oxford Elbow Score (OES) and Mayo Elbow Performance Score (MEPS) (objective). Radiographic follow-up was with standard radiographs., Results: Mean follow-up was 92.2 months (range, 24-151). Mean patient age at surgery was 62.8 years (range, 45-81). The mean MEPS was 87.1 points, with excellent results in 26 cases, good results in 9 cases, fair in 2, and poor results in 4. The mean DASH score was 15.9 and the mean OES was 40.5, with satisfactory results in 30 cases. Twenty patients experienced complications and 2 required revision surgery., Discussion: EHA is a valuable surgical option in selected patients with comminuted distal humeral joint fractures that cannot be reconstructed with stable fixation and in those with malunion of the articular surface of the humerus. EHA offers potential advantages, especially in active elderly patients and in those aged less than 70 years. It is essential to achieve joint stability, restoring medial and lateral ligament function besides the integrity of the coronoid process. An intact olecranon surface without signs of degenerative changes is also critical for EHA success., Conclusion: Our mid- and long-term experience with EHA is favorable, with a high proportion of satisfactory results and long survival rates for both lesion types. In selected patients with acute and post-traumatic injuries, EHA is a valuable surgical option., (Copyright © 2022 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

Background: Anatomic surgical reduction of intra-articular fractures of the distal humerus is important to achieve the best long-term outcomes and prevent post-traumatic arthritis. In this study we compared the radiographic reduction using the trochleocapitellar index. We also correlated the trochleocapitellar index to the functional outcomes next to the comparison of the triceps brachii lifting approach and olecranon osteotomy approach, 2 common approaches for distal humeral fractures., Methods: From January 2006 to June 2016, patients with elbow fractures were registered in 4 centers. The trochleocapitellar index, a ratio between the angle of the capitellum and the trochlea to the midline of the distal humerus on anterior-posterior radiographs, was calculated for included patients. Functional outcomes were measured using the Oxford Elbow Score and the Mayo Elbow Performance Score. Bone healing was measured using radiographic union scoring., Results: There were 86 patients enrolled: 46 in the olecranon osteotomy group and 40 in the triceps lifting group. Functional outcomes and bone healing did not differ between the approaches. Functional results had a medium correlation with the trochleocapitellar index, which did not differ between the 2 approaches (olecranon osteotomy group, κ = 0.56; triceps lifting group, κ = 0.57; P = .7932)., Conclusions: The trochleocapitellar index has a moderate predictive value on the functional results after 12 months after open reduction and internal fixation of intra-articular distal humeral factures. There is no difference in reduction, as measured by trochlear index and functional outcome scores, between the olecranon osteotomy approach and the triceps brachii lifting approach groups., (Copyright © 2018 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: Chronic coronoid deficiency can occur subsequent to coronoid fracture malunion/nonunion or to coronoid hypoplasia or dysplasia resulting from injury during development. Several surgical options have been described to treat this difficult condition, but results are equivocal. We hypothesized that a modified coronoid reconstruction using a radial head osteochondral graft could restore elbow stability and congruity and that a technique involving rigid internal fixation would promote graft union., Methods: The coronoid was reconstructed using an osteochondral fragment from a frozen allograft radial head in 3 young women affected by complex post-traumatic elbow instability and incongruity resulting from coronoid deficiency. To promote bone healing, the fragment was kept as large as could be fitted in place, the cut surface compressed onto the remaining coronoid was as large as possible, the medial portion of the radial head (containing dense bone) was used, and 3 lag screws were inserted in different directions., Results: At a mean follow-up of 26 months, all 3 patients achieved a painless, congruent stable joint with a functional range of motion. Computed tomography scans performed 3 months after surgery showed complete union of the graft in all the patients. Each patient rated herself as "almost normal" or "greatly improved" on the Summary Outcome Determination scale., Conclusion: Coronoid reconstruction with a radial head osteochondral allograft was successful in restoring stability and function in chronically unstable elbows with coronoid deficiency. Strong fixation using a large segment of the medial radial head achieved rapid graft healing., (Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

Background: Total elbow arthroplasties (TEAs) are usually indicated in chronic inflammatory arthropathies. This procedure has also recently been used in complex distal humeral fractures and nonunions in selected patients. This study analyzed the clinical and radiographic outcomes in patients treated for nonunions around the elbow region with a minimum follow-up of 3 years., Methods: Between May 2002 and June 2012, 20 patients affected with distal humeral nonunions were treated with TEA. All patients were assessed clinically using the Mayo Elbow Performance Score and radiographically to evaluate the positioning of the prosthetic components and signs of loosening. Statistical analyses were performed to investigate the presence of clinical and radiographic variables as predictive factors of poor functional outcomes., Results: The Mayo Elbow Performance Score of the affected arm improved significantly between the preoperative period and follow-up. Results were good or excellent in 90% of the patients even if a high rate of complications (30%) was encountered. The development of complications after surgery and stages II, III, and IV radiolucency, according to the Morrey criteria, were predictive factors of poor outcomes., Conclusions: According to the satisfactory results observed in this study, TEA could be indicated in selected patients aged older than 70 years with low functional demands and affected with distal humeral nonunions in which obtaining a stable fixation is difficult., (Copyright © 2015 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: This article presents the experience at the Rizzoli Orthopaedic Institute in the treatment of intracapsular osteoid osteoma (OO) of the elbow by computed tomography-guided percutaneous radiofrequency thermal ablation (RFA)., Materials and Methods: Our team performed more than 800 RFA procedures to treat OO up to 2010. In 27 cases, the lesion site was the articular area of the elbow (humerus in 13 cases, ulna in 13, and radius in 1). These patients were reviewed and assessed for eradication rate, incidence of complications, and functional results measured by the Mayo Elbow Performance Score. The outcome was evaluated after a mean follow-up period of 67.4 ± 35.3 months (range, 24-128 months)., Results: The mean duration of symptoms at the time of diagnosis was 31.0 ± 19.8 months (range, 5-72 months). All patients complained about pain, and in 24 of 27 cases (88.8%), the joint function was significantly impaired by the presence of OO (pretreatment score, 54.8). After RFA, the Mayo Elbow Performance Score improved by a mean of 37.7 ± 14.8 points, with 25 of 27 patients (92.5%) scoring 90 to 100 points at final follow-up. OO recurred in only 1 patient (3.7%), 5 months after the procedure. However, this was successfully retreated by RFA. No adverse effects were observed, and all patients were free of disease at the final follow-up., Discussion: The RFA procedure can be technically challenging in difficult sites such as the elbow joint. The low invasiveness of RFA compared with traditional surgery allows excellent functional recovery. RFA of elbow OO is effective and safe, and it should be considered the first-choice treatment for this disease., (Copyright © 2014 Journal of Shoulder and Elbow Surgery Board of Trustees.
