One surgical option to manage idiopathic osteoarthritis of the elbow is an ulnohumeral arthroplasty. A potential complication to avoid during this procedure is inadvertent over penetration of the anterior cortex of the humerus. If this occurs, injury to the median nerve and brachial artery is possible as these structures may lie within 7 mm of the anterior humerus. This surgical technique describes technical tips in regards to patient positioning and specific instrument usage that serve to diminish the risk of this catastrophic complication occurring by allowing these critical neurovascular structures to fall away from the anterior humerus.

Elbow kinematics with increased lengthening of a radial head arthroplasty evaluated with dynamic radiostereometric analysis.
Bone Joint J

AutoRSA Research Group, Orthopaedic Research Unit, Aarhus University Hospital, Aarhus, Denmark.
Aims: The aim of this study was to evaluate the kinematics of the elbow following increasing length of the radius with implantation of radial head arthroplasties (RHAs) using dynamic radiostereometry (dRSA).
Methods: Eight human donor arms were examined by dRSA during motor-controlled flexion and extension of the elbow with the forearm in an unloaded neutral position, and in pronation and supination with and without a 10 N valgus or varus load, respectively. The elbows were examined before and after RHA with stem lengths of anatomical size, + 2 mm, and + 4 mm.

Background: Although many studies have focused on the degenerative changes of the ulnohumeral and radiohumeral joints in osteoarthritis (OA) of the elbow, the proximal radioulnar joint (PRUJ), which facilitates the pronation and supination motions of the forearm, has not been comprehensively evaluated.
Purpose: To assess the prevalence of PRUJ OA in patients diagnosed with OA of the elbow using computed tomography (CT) images and to establish an association between the CT findings and clinical manifestations.
Study Design: Cross-sectional study; Level of evidence, 3.
The Effect of Power Grip on Ulnar Variance A Computed Tomography Study of the Wrist and Elbow.
Bull Hosp Jt Dis (2013)
December 2024
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: The objective of this study was to perform a polyethylene wear test on a nonmechanically linked total elbow arthroplasty implant using a clinically relevant in-vitro elbow wear test methodology that simulated 10 years of use in the light to moderate activity of daily living range.
Materials And Methods: The test protocol applied an 80° arc of ulnohumeral motion beginning at 30° shy of full extension and progressing to 110° of flexion. Force was applied at 7° to recreate a valgus load on the elbow.

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).
