Division of Orthopaedic Surgery, McGill University Health Centre, Montreal, Quebec, Canada.

Background: Current repair techniques using cortical button fixation cannot achieve anatomic reconstruction of the distal biceps when performed through a single-incision anterior approach. We recently introduced a single-incision technique that uses flexible guide pins and flexible reamers to allow for an insertion point on the tuberosity that more closely approximates the anatomic footprint of the distal biceps.

Purpose: To investigate the safety of this technique with regard to nerve injury by comparing the guide pin position relative to the posterior interosseous nerve in 16 cadaveric elbows through use of a flexible versus rigid reamer. Read More

Background: Due to anatomic variance in subscapular nerve innervation patterns, it is theorized that the dysfunction of the subscapularis could be the result of iatrogenic denervation during mobilization of the subscapularis while exposing the anterior glenohumeral joint in anterior surgical approaches. The purpose of this study was to describe innervation patterns of the subscapularis and to characterize a safe zone when conducting an anterior surgical approach.

Methods: The study used 6 human cadaveric shoulder specimens (12 shoulders total). Read More

Background: The posterior interosseous nerve (PIN) is occasionally damaged during distal biceps tendon repair. But to our knowledge, no studies have examined the position of the PIN in relation to the bicipital tuberosity in full supination, which is the recommended position during single-incision distal biceps repair or reconstruction QUESTIONS/PURPOSES: (1) What is the anterior safe zone when exposing the anterior tuberosity with the arm in supination? (2) When drilling the radial tuberosity for bicortical button placement in full supination, how should the drill be angled to avoid PIN injury?

Methods: Fifteen adult cadaver elbows had the PIN dissected around the proximal radius. The position of the PIN was measured relative to the most ulnar aspect of the radius at three sites in full supination: at the bicipital tuberosity (bicipital tuberosity-PIN), 10 mm proximal to the bicipital tuberosity (bicipital tuberosity-proximal), and 10 mm distal to the bicipital tuberosity (bicipital tuberosity-distal).

Division of Anatomy, University of Toronto, Toronto, ON, Canada.

Objective: Long head biceps tendon peritendinous or sheath injections are routinely administered at or immediately distally to the bicipital groove. The main indication for injection remains the clinical diagnosis or treatment of biceps tendinopathy, although true inflammation of the tendon within the bicipital groove is rare. Because the tendon sheath is merely an extension of the joint cavity, it is plausible to assume that an injection into the sheath would result in intraarticular spread. Read More

Proximal radioulnar synostosis is a rare but highly disabling posttraumatic complication in periarticular elbow injuries. Surgical treatment is an option for functionally limiting proximal radioulnar synostosis; however, the approach can endanger local neurovascular structures, especially if the synostosis affects the level of the bicipital tuberosity. We report two cases of proximal radioulnar synostosis with a preoperative prono-supination range of motion of 0° and 15° treated by a reverse Sauvé-Kapandji procedure resecting a 1-cm section of the radial shaft distal to the bicipital tuberosity and leaving the synostosis in place.
