Background: Radiocapitellar arthroplasty fills a treatment void for young patients who experience isolated capitellar fractures or radiocapitellar osteoarthritis who are not candidates for total elbow arthroplasty. The outcomes of this procedure are sparsely reported. We designed a meta-analysis to determine the utility of radiocapitellar arthroplasty with respect to functional and patient reported outcomes.
Methods: The PubMed database was searched for relevant studies. Only studies published in English language that assessed patient reported outcomes following radiocapitellar arthroplasty were included in this study. Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses for 2020.
Results: The initial review yielded 562 studies that met the criteria. After excluding duplications and confounding factors, eight case series were identified for review. Of the eight studies, seven were eligible for inclusion in the meta-analysis for Mayo Elbow Performance Score, flexion-extension arc, and pronation-supination arc. The pooled standard mean difference was found to be statistically significant between pre-operative and post-operative outcomes for Mayo Elbow Performance Score (SMD = 3.04, 95% CI [2.40, 3.67]), flexion-extension arc (SMD = 1.28, 95% CI [0.73, 1.83]), and pronation-supination arc (SMD = 0.81, 95% CI [0.43, 1.18]). Cochran's -test and statistics indicated statistically significant heterogeneity for Mayo Elbow Performance Score ( = .04, = 54%) and flexion-extension arc ( < .01, = 67%).
Conclusions: Patients undergoing radiocapitellar arthroplasty showed statistically significant improvements in flexion-extension arc, pronation-supination arc, and Mayo Elbow Performance Scores compared to pre-operative measures.

Radiocapitellar arthroplasty has been shown to improve pain and function in patients with a degenerative joint. Due to problems with the loosening of the radial head component, one of the few available systems was removed from the global market. This offered specific challenges in terms of treatment strategies when one or both components of a system that is no longer available fail.

Although an increase in ulnar variance with power grip is well documented in the medical literature, there is a paucity of information concerning its mechanism. This concept was examined in five healthy individuals using computed tomography of their wrists and elbows. Images were obtained of both joints in the resting position and with maximum power grip.

Background: Radiocapitellar arthritis can cause pain, loss of motion, and impaired elbow function. Current surgical treatment options are limited. We have developed an original and simple surgical technique to address this, called arthroscopic matched osteoplasty of the radial head (AMOR).

Monteggia injuries are rare childhood injuries. In 25-50% of cases, however, they continue to be overlooked, leading to a chronic Monteggia injury. Initially, the chronic Monteggia injury is only characterized by a moderate motion deficit, which is often masked by compensatory movements.

Background: The incidence of radial head fractures is increasing, and radial head arthroplasty (RHA) is being more frequently used as treatment for irreparable fractures. Our objective was to compare radiocapitellar pressure between the native joint and 2 radial head prosthesis conditions: (1) a prosthetic head that was aligned to the forearm axis of rotation and (2) the same prosthesis with an axisymmetric nonaligned head.
Methods: Ten cadaveric specimens received a pressfit radial head prosthesis (Align; Skeletal Dynamics) for both prosthetic testing conditions.
