Painful Entrapment of the Lateral Antebrachial Cutaneous Nerve After Distal Biceps Repair: A Case Report.

Case: A 46-year-old man presented with continued pain after distal biceps repair. On revision surgery, he was found to have entrapment of the lateral antebrachial cutaneous nerve (LABCN). After nerve transection, relocation to its native course, and subsequent repair, the patient experienced complete resolution of his preoperative symptomatology.

The utility of the biceps palpation-rotation test in diagnosing partial distal biceps tendon tears.

Background: Partial tears of the distal biceps tendon can be difficult to diagnose based on clinical examination and magnetic resonance imaging (MRI).

Methods: Patients from a single surgeon's practice from 2000 to 2018 with a partial distal biceps tendon tear were retrospectively reviewed to determine the utility of the distal biceps palpation-rotation test in the detection of partial tears. This test is performed by palpating the bicipital tuberosity at the lateral forearm while ranging the forearm from supination to pronation with the arm adducted at the patient's side and the elbow flexed to 90°.

Augmentation of Distal Biceps Tendon Ruptures With the Lacertus Fibrosus: A Biomechanical Study in a Tendon-Deficient Model.

Background: Chronic distal biceps tendon ruptures may require tendon graft augmentation secondary to tendon attrition or retraction. The lacertus fibrosus is a local, cost-effective graft that can be used to supplement reconstruction.

Purpose: To compare the biomechanical strength of distal biceps tendon repairs with and without lacertus fibrosus augmentation in a tendon-deficient cadaveric model.

Distal biceps repair using the lacertus fibrosus as a local graft.

Background: We report a case series of 15 patients who underwent a new surgical technique that uses a transfer of the lacertus fibrosus to augment the repair of the distal biceps tendon. This technique seeks to minimize the need for and potential complications associated with autogenous or allograft tendon reconstruction in this clinical scenario.

Methods: We reviewed the clinical outcomes of patients who both underwent a lacertus transfer for biceps tendon reconstruction during a 10-year period and had at least 6 months of follow-up.

Operative treatment of chronic distal biceps tendon ruptures.

Chronic biceps tendon ruptures typically involve tendon retraction, scarring, and even compromised tissue. Indirect repair, such as tenodesis to the brachialis, does not provide optimal functional recovery. Chronic biceps tendon ruptures can be reconstructed with autogenous grafts (semitendinosis, tensor fascia lata) or allografts (typically Achilles tendon).

Articular cartilage injuries of the capitellum interposed in radial head fractures: a report of ten cases.

Ten cases of Mason type I and type II isolated radial head fractures are reported, in which an unexpected cartilaginous fragment of the capitellum trapped within the radial head fracture was identified at the time of surgery. In no case was this injury pattern identified on preoperative imaging, including computed tomography in 2 cases. Five patients did have preoperative mechanical findings with forearm rotation.

Lateral compression injuries in the pediatric elbow: Panner's disease and osteochondritis dissecans of the capitellum.

Lateral compression injuries of the elbow typically occur in throwing athletes and gymnasts. In the preadolescent and adolescent patient, these injuries predominantly include Panner's disease and osteochondritis dissecans. Panner's disease, an osteochondrosis of the capitellum, is a rare disorder that usually affects the dominant extremity in individuals younger than age 10 years.
