The purpose of this study was to evaluate the safety and the effectiveness of a new modified anconeus transfer technique in revision surgery for refractory lateral epicondylitis of the elbow. A modified anconeus muscle transfer was performed in nine patients with persistent symptoms after previous surgical release of the common extensor origin. The original technique was modified by using only half of the anconeus muscle. Patients were clinically evaluated, including quickDASH score and grip strength measurement. At a mean follow up period of 36 months, 4 patients had an excellent result, 3 a good result and 1 a poor result. All patients rated their clinical situation as better than before surgery. All but one patient said to be happy with the result and they would undergo the procedure again. The mean quickDash score at the follow up was 10.6 (SD 14.4). No complications were observed. The modified Anconeus muscle transfer is a safe and effective procedure in patients with persistent lateral epicondylitis complaints after a previous surgical release.

Inducing postactivation potentiation alters human motor unit behavior of the elbow extensors during unconstrained velocity contractions.

The purpose of this study was to test whether inducing postactivation potentiation (PAP) altered motor unit (MU) activity during dynamic isotonic contractions. From 12 participants (3 females), 39 MUs were recorded from the anconeus ( = 31) and lateral triceps brachii ( = 8) with fine-wire electrodes during elbow extensions at 50% and 75% of peak power with, and without PAP. To induce PAP, participants produced a 2-s ramp conditioning contraction (CC) up to maximal isometric elbow extension with a 3-s hold.

Article Synopsis
- * The anconeus hemipeel approach offers improved access to the distal humerus by reflecting the anconeus muscle, serving as a potential alternative to the more invasive olecranon osteotomy.
- * This study presents the first clinical outcomes for patients treated with the anconeus hemipeel approach, highlighting its effectiveness in managing comminuted intraarticular distal humerus fractures without the added complications of an olecranon osteotomy.

When the lateral collateral ligament (LCL) complex fails to support the radiocapitellar and ulnohumeral joints in advanced stages of insufficiency, the patient experiences posterolateral rotatory instability (PLRI). Open lateral ulnar collateral ligament repair with a ligamentous graft has been the standard treatment for PLRI. Despite producing good clinical stability rates, this method is associated with significant lateral soft-tissue dissection and a lengthy recovery period.

Fixation of radial head fracture with minimally invasive posterior approach remains a significant challenge. The aim of this study was to determine the feasibility of trans-anconeus posterior elbow approach and to observe lateral ulnar collateral ligament (LUCL) in extended elbows. This cadaveric study was performed in twenty upper limbs of fresh fixed adult male cadavers.

Posterolateral rotatory instability is concerning pathology in patients with recalcitrant lateral elbow pain. An arthroscopic technique can be used to perform reconstruction of lateral collateral ligament for eradicating the instability and also to manage concomitant lesions in a simultaneous operation. Similar to the modified Brostrӧm procedure using an inferior extensor retinaculum to augment the lateral collateral ligament for lateral ankle instability, in our Technical Note, we use anconeus muscles and annular ligament to augment the lateral collateral ligament for elbow instability during the reconstruction, allowing all tissue to heal with the bone by using a knotless technique.
