Case Report: Delayed Surgical Reconstruction with an Achilles Tendon Allograft for Triceps Tendon Rupture: Technique and Results

Triceps tendon injuries are relatively rare and represent less than 1% of all tendon injuries [1-3]. Ruptures typically occur following an eccentric force applied against an actively contracting triceps, but may occur following direct trauma [4-8].Tendon ruptures can occur due to intrinsic or extrinsic factors, and risk rupturing with a rapidly applied force [9-10]. The most common mechanism typically involves a fall or direct blow to the posterior aspect of the elbow [2-3]. A history of anabolic steroid use, local steroid injection for olecranon bursitis and chronic tendinopathy can predispose to rupture [4,7,11-14]. In addition, medical comorbidities such as chronic renal disease, metabolic bone disease, diabetes, lupus, secondary hyperparathyroidism and rheumatoid may also be risk factors for rupture [4,5,7,8,11,14]. Males are twice as likely to sustain these injuries [13]. These injuries may be missed initially due to swelling and pain following an acute injury [5]. Operative management is typically required in the event of a complete rupture, however, management can be challenging with professional body builders and athletes. While there are case reports published on triceps tendon ruptures, current literature lacks consensus on a standardized technique for management of these injuries [7].
