Project description:Purpose of reviewDistal biceps tendon ruptures (DBTR) are uncommon injuries in 40- to 50-year-old men but occur at a younger age in the athlete population. The distal biceps tendon is an important supinator of the forearm and flexor of the elbow. A complete injury results in limiting function in the upper extremity. The current review evaluates the different options in management and the current literature on return to play in athletes.Recent findingsThe distal biceps tendon inserts on the posterior aspect of the radial tuberosity as two independent heads. The long head footprint is more proximal and posterior giving it a better lever arm for supination. The short head footprint is more distal and anterior giving it a better lever arm for flexion. Surgical anatomic repair is highly recommended among the athlete population, to restore proper function of the upper extremity. There is scarce literature on return to play among athletes. The most recent studies on high-performance athletes are on National Football League (NFL) players. These studies showed that 84-94% of NFL players returned to play at least one game after distal biceps repair. Compared to matched control groups, there was no difference in the player's performance after surgery. Anatomic repair of DBTR results in excellent outcomes, high return to work, and high rate of return to play among athletes. When compared to matched control groups, NFL players have the performance score and play the same number of games after surgery.

Project description:Distal biceps tendon ruptures are thought to be secondary to an acute forceful eccentric load on a degenerative tendon. Nonoperative treatment following rupture leads to significantly decreased forearm supination and elbow flexion strength. There are several techniques described in the literature for repair. This article describes, with video illustration, distal biceps tendon repair using a double tension slide technique with 2 No. 2 high-tension nonabsorbable composite sutures.

Project description:Distal biceps tendon ruptures are uncommon injuries that can cause impairment in range of motion and function. While distal bicep tendon repair to the radial tuberosity has been demonstrated to restore function and strength, there is a lack of consensus on the optimal technique. The purpose of this Technical Note and video is to provide our preferred method of repair using an open, onlay-tissue fixation with all-suture anchors (FiberTak; Arthrex) and anatomic positioning of the biceps tendon on the radial tuberosity.

Project description:BackgroundDistal biceps tendon repair using endobutton fixation has shown the best biomechanical results in terms of pullout strength. Here, we compared Sethi's enhanced tension adjustable endobutton technique known as the "tension slide technique" to a new knotless endobutton fixation technique without a post-fixation screw. Our new approach is as effective as the tension slide technique in terms of pullout strength and gapping after early mobilization.MethodsA biomechanical cadaveric study with 16 paired arms was performed. With the radius held in place, the distal biceps tendon was loaded at 100 N for 500 cycles and the load was then increased until failure. Gapping after loading cycles and maximum load to failure were recorded and compared.ResultsMedian bone-tendon gapping was 5.77 mm (interquartile range (IQR) 4.84-9.11) for tension slide technique and 4.72 mm (IQR 1.77-6.16) for the knotless fixation (p = 0.047). Median load to failure was 257.87 N (IQR 222.07-325.35) in the tension slide technique group and 407.78 N (IQR 358.54-485.20) in the knotless group (p = 0.047).DiscussionThe knotless endobutton provides better pullout strength and elongation results compared to the tension slide technique without the use of an interference screw, allowing early mobilization in order to faster return to daily living activities.Level of evidence: Basic science study.

Project description:Distal biceps tendon ruptures are treated operatively in active healthy individuals. Treatment consists of either single- or double-incision techniques, each with its own set of advantages and complications. The double incision was traditionally preferred for a more anatomic reattachment of the distal biceps tendon, but there has been renewed interest in the single-incision anterior approach given its lower risk for heterotopic ossification. However, current single-incision techniques cannot achieve anatomic reconstruction of the distal biceps because of a restricted operational angle with standard rigid instruments. The purpose of this study was to introduce a single-incision technique using flexible instrumentation, flexible guide pins, and flexible reamers that allows for an insertion point that better approximates the anatomic footprint of the distal biceps on the tuberosity. This offers the theoretical advantage of restoring forearm supination mechanics, while still maintaining the benefits of a single limited anterior exposure.

Project description:There are several techniques that have been described for distal biceps tendon repair but there is still controversy regarding the optimal technique. Our hypothesis is that the single-incision technique will have a similar complication rate and functionally equivalent restoration of function compared with the two-incision approach. A retrospective review of consecutive biceps tendon repairs was performed at one institution over a 5-year period. Thirty-six patients met the inclusion criteria and 26 were available for follow-up including subjective assessment, physical examination, and strength testing. Patients were divided into two groups based on the surgical approach utilized: 12 patients underwent single-incision repair and 14 had a two-incision repair. The average follow-up was 33 months (minimum 13; maximum 75). There were no statistically significant differences in regards to flexion strength or endurance, supination strength or endurance, or complication rates between the two techniques. In conclusion, both surgical techniques led to adequate restoration of strength with a low complication rate. Both techniques are safe to perform and should be guided by surgeon comfort with the approach.

Project description:Irreparable distal biceps tendon tears typically are treated using a free tendon graft. We asked whether our new method to fix the graft--using two suture anchors--yields similar results to our previous bone canal method. We compared the two methods for strength, endurance, and clinical findings. There were two groups, the suture anchor group (Group A, seven patients) and the bone canal group operated on before suture anchors (Group B, seven patients). The patients were males with a mean age at surgery of 44.9 years. The operative delay from primary trauma to index surgery averaged 5.9 months. The minimum followup was 2 years (mean, 11.1 years; range, 2-23 years). The mean arc of elbow motion was 0 degrees to 132 degrees, pronation 83 degrees, and supination 80 degrees. Compared with the contralateral side, the maximal peak torque was 84% in supination and 91% in pronation, and the maximal static elbow flexion strength was 94%. The Mayo elbow score averaged 99 in Group A and 100 in Group B. There were no major differences between the two groups. Our novel modification to fix a tendon graft yields equal clinical outcomes compared with the bone canal method for treatment of irreparable distal biceps tendon injuries.Level IV, therapeutic study.

Project description:Distal biceps tendon ruptures are uncommon injuries responsible for only 3% of all injuries to the biceps tendon. For most of these cases, unless the patient is elderly or infirm, conservative management should be avoided and the injury should be treated with a surgical procedure to reattach the bicep tendon to the radial tuberosity. In this Technical Note and accompanying video, we describe an anatomic single-incision technique using 2 intramedullary soft anchors, which decreases the likelihood of complications associated with bicortical drilling and metal suspensory fixation.

Project description:Distal biceps tendon ruptures are uncommon and generally occur in men aged 30 to 50 years in their dominant arm as a result of a strong eccentric load. Numerous surgical exposures and methods of fixation exist for repair of a ruptured distal biceps tendon. The goal of surgical management is to restore the anatomic footprint of the biceps tendon on the radial tuberosity to maximize flexion strength, supination strength, and muscle endurance. When compared with 2-incision repair techniques, single-incision repairs historically may not have restored the anatomic footprint of the distal biceps. Single-incision repair with the ArthroTunneler is a safe and effective technique that provides the anatomic restoration of a 2-incision approach with the decreased complication profile of a single-incision approach and does not require suture anchors, buttons, screws, or other implants.

Project description:Surgical repair of distal biceps tendon rupture is a technically challenging procedure that has the potential for devastating and permanently disabling complications. We report two cases of posterior interosseous nerve (PIN) injury following successful biceps tendon repair utilizing both the single-incision and two-incision approaches. We also describe our technique of posterior interosseous nerve repair using a medial antebrachial cutaneous nerve graft (MABC) and a new approach to the terminal branches of the posterior interosseous nerve that makes this reconstruction possible. Finally, we advocate consideration for identification of the posterior interosseous nerve prior to reattachment of the biceps tendon to the radial tuberosity.
