Humeral fracture following subpectoral biceps tenodesis in 2 active, healthy patients.

چکیده
Pathology involving the long head of the biceps tendon is a common and significant cause of shoulder pain. For active patients with refractory biceps tendinosis, tenodesis of the tendon to either soft tissue or the humerus is the preferred surgical treatment. Subpectoral biceps tenodesis to the humeral diaphysis with an interference screw has been gaining popularity as an effective method for treating biceps pathology, as clinical studies have demonstrated favorable outcomes with low rates of postsurgical complications with this technique. This procedure involves drilling a cortical hole distal to the bicipital groove for placement of the tendon and bioabsorbable screw. The size, depth, and location of this hole create a stress riser effect in the humerus, which previously was thought to be insignificant; however, several case reports exist in the literature describing postoperative fracture through the humeral drill hole. This report presents 2 patients with postoperative humeral fractures involving the subpectoral tenodesis drill hole that occurred within 6 months of surgery. This finding suggests that this complication may be more prevalent in active patients than previously thought.

BACKGROUND Humeral fracture after subpectoral tenodesis of the long head of biceps tendon (LHB) is a rare but devastating complication. PURPOSE To determine whether malpositioned (laterally eccentric) tenodesis screw placement has an influence on humerus strength reduction compared with central placement. STUDY DESIGN Controlled laboratory study. METHODS Two groups, each consisting of 10 ...

BACKGROUND Long head biceps tendon pathology is a common cause of anterior shoulder pain and is often associated with other shoulder conditions, such as rotator cuff tears and osteoarthritis. It is well accepted that older patients are at increased risk for major and minor peri- and postoperative complications. The purpose of this study is to investigate patients over 65 years old who underwent...

BACKGROUND Tenodesis of the long head of the biceps tendon is a common procedure used to alleviate pain caused by instability or inflammation of the tendon. The purpose of this study is to report on the incidence and types of complications following an open subpectoral biceps tenodesis (OBT) procedure. HYPOTHESIS Our hypothesis was that the rate of adverse events after OBT was low. METHODS ...

BACKGROUND Bioabsorbable interference screw fixation has superior biomechanical properties compared to suture anchor fixation for biceps tenodesis. However, it is unknown whether fixation technique influences clinical results. HYPOTHESIS We hypothesize that subpectoral interference screw fixation offers relevant clinical advantages over suture anchor fixation for biceps tenodesis. STUDY DES...
