Project description:Over the past few decades, there has been increased awareness of pectoralis major muscle injuries necessitating further evaluation of management options and, in particular, surgical repair. Injury typically occurs when an eccentric load is applied to the muscle, such as with bench pressing, and failure usually occurs through the tendon. Although nonoperative management is sometimes appropriate, given the injury's propensity for young, active male patients, surgical intervention is often warranted. Because the injury typically occurs at the muscle-tendon interface, surgery focuses on repair of the avulsed tendon into its anatomic attachment site. We describe the use of a unicortical suture button to repair the ruptured tendon. This technique achieves the goals of strong fixation and anatomic repair of the tendon back into its native footprint.

Project description:PurposeTo describe the proportional anatomic relationship of the long head of the biceps tendon (LHBT) myotendinous junction (MTJ) to pectoralis major tendon (PMT) and to provide an up-to-date review of the current literature.MethodsTen fresh frozen cadaveric specimens were used. A deltopectoral approach was used for exposure and anatomical location of the MTJ as well as the proximal and distal borders of the PMT were identified by 2 fellowship-trained shoulder and elbow surgeons. The longitudinal length of the PMT, the distance from the long head of the biceps (LHB) MTJ to the proximal border of the PMT (pMTJ), and the distance from the LHB MTJ to the distal border of the PMT (dMTJ) were recorded. The relationship between the pMTJ and the PMT length was then reported as a ratio.ResultsThe PMT was found to have a length of 5.16 ± 0.64 cm (4.1-6.1 cm). The pMTJ was 1.14 ± 0.52 cm (0.5-1.9 cm), and the dMTJ was 4.02 ± 0.91 cm (2.5-5.3 cm). The pMTJ/PMT ratio was 0.23 ± 0.11 (0.10-0.39).ConclusionsWe found the average length of the PMT footprint to be 5.16 cm with the LHB MTJ beginning 1.14 cm distal to its proximal border.Clinical relevanceIt is important to understand the LHBT and its relationship to surgically relevant surrounding anatomy to allow for appropriate tensioning and improved patient outcomes in the treatment of LHBT shoulder pathology.

Project description:Pectoralis major tendon rupture is a relatively rare injury, resulting from violent, eccentric contraction of the muscle. Over 50% of these injuries occur in athletes, classically in weight-lifters during the 'bench press' manoeuvre. We present 13 cases of distal rupture of the pectoralis major muscle in athletes. All patients underwent open surgical repair. Magnetic resonance imaging was used to confirm the diagnosis in all patients. The results were analysed using (1) the visual analogue pain score, (2) functional shoulder evaluation and (3) isokinetic strength measurements. At the final follow-up of 23.6 months (14-34 months), the results were excellent in six patients, good in six and one had a poor result. Eleven patients were able to return to their pre-injury level of sports. The mean time for a return to sports was 8.5 months. The intraoperative findings correlated perfectly with the reported MRI scans in 11 patients and with minor differences in 2 patients. We wish to emphasise the importance of accurate clinical diagnosis, appropriate investigations, early surgical repair and an accelerated rehabilitation protocol for the distal rupture of the pectoralis major muscle as this allows complete functional recovery and restoration of full strength of the muscle, which is essential for the active athlete.

Project description:Pectoralis major (PM) ruptures are uncommon injuries, although they are becoming more frequent. We report a case of a PM rupture in a young male who presented with axillar pain and absence of the anterior axillary fold after he perceived a snap while lifting 200?kg in the bench press. Diagnosis of PM rupture was suspected clinically and confirmed with imaging studies. The patient was treated surgically, reinserting the tendon to the humerus with suture anchors. One-year follow-up showed excellent results. The patient was recording his training on video, so we can observe in detail the most common mechanism of injury of PM rupture.

Project description:IntroductionThe pectoralis major muscle (PM) is a large muscle on the anterior chest wall. The rupture of the PM is a rare entity in literature and most incidences had been reported frequently in weight lifting and contact sports. Acute repair of PM rupture yielded better outcome as compared to non-operative treatment in active individuals who wish to return to their sports.Case reportWe presented a case of a champion in bodybuilding who lifted a heavy weigh during his routine exercises, which caused a rupture in the musculotendinous junction of the left pectoralis major muscle.DiscussionAs it is rare to meet ruptures in this site of pectoralis major, we decided to insert anchors into the humeral bone (as in avulsions and tendon's tears), and to duplicate the suturing levels in multiple directions (as in muscular belly ruptures).ConclusionOur aim here is to confirm that the rupture of the musculotendinous junction of the pectoralis major muscle is rare and difficult to deal, but the acute surgical treatment by inserting anchors into the humerus, and duplicating the suturing layers in multiple directions can give good results especially in athletes.

Project description:Pectoralis major tendon ruptures can lead to significant functional deficits that affect high-level athletic and labor-intensive activities. In active populations operative repair of the ruptured pectoralis major tendon has shown significant advantages over nonoperative treatment. We describe a novel surgical technique for pectoralis major repair with tension button fixation. This study included 12 recreational athletes and 2 professional athletes. The initial results were measured subjectively after a minimum of 6 months by the Single Assessment Numeric Evaluation score, the American Shoulder and Elbow Surgeons score, and the ability to return to the patient's sport at a preinjury level. Objectively, strength was measured with resisted horizontal adduction of the arm for both repaired and contralateral sides. Of the 12 recreational patients, 8 returned to their sport at preinjury levels, and the 2 professional athletes returned to their sport at full capacity in the National Football League. The mean Single Assessment Numeric Evaluation score was 87, and the mean American Shoulder and Elbow Surgeons scores were 99 for both the operative and contralateral sides. Isokinetic strength testing showed no significant differences between the operative and nonoperative sides. Patients with pectoralis major tendons repaired with the proposed tensioned cortical button technique had excellent results. This new technique provides a reliable method of repair in an efficient and safe manner.

Project description:A powerlifting athlete ruptured his left tendon of the pectoralis major muscle while attempting to lift 160 kg in a Brazilian bench press championship. The injury seemed to occur in the concentric phase of exercise; however, the more common mechanism of rupture is during the eccentric phase. The tendon was reinserted to the humerus 3 weeks later with screws and washers. The athlete returned to competitive activities after 5 months. One year later he lifted 170 kg and won the national championship.

Project description:Distal triceps rupture is an uncommon but debilitating injury, and surgical fixation is almost invariably warranted. A number of techniques have been described in the literature in which combinations of transosseous tunnels and bone anchors have been used. We describe a modification to existing techniques-the triceps pulley-pullover technique with all-suture anchors. This technique minimizes bone loss, while maximizing the bone-tendon contact area and creating a double-row repair to optimize strength and healing.

Project description:Although injuries of the pectoralis major muscle are generally uncommon, ruptures of the pectoralis major are occasionally seen in younger, more active patients who participate in weightlifting activities. These injuries usually occur during maximal contraction of the muscle, while in extension and external rotation. In the case of a rupture, operative treatment is advocated especially in young, active patients regardless of the chronicity of the injury. Various surgical techniques for reattachment of the avulsed tendon have been described, but bone tunnel and suture anchor repair techniques are most widely used. In this Technical Note, we present our preferred technique for acute pectoralis major rupture repair involving use of cortical buttons for tendon stump-to-bone fixation.
