BACKGROUND: Biceps tenodesis reduces the incidence of Popeye deformity occurring with tenotomy, but pain may occur with tenodesis superior to or within the bicipital groove. Arthroscopic suprapectoral tenodesis is an attractive alternative. The purpose of this study was to establish landmarks for arthroscopic suprapectoral tenodesis and determine the appropriate fixation point to optimize muscle tension. METHODS: Twelve fresh cadaveric shoulders were dissected. Urethane polymer was injected into the axillary artery...

We sought to identify changes in individual muscle hardness after a full marathon and to track time-dependent changes using ultrasound strain elastography (SE). Twenty-one collegiate marathon runners were recruited. Muscle hardness (i.e., strain ratio, SR) was measured using SE for the rectus femoris (RF), vastus lateralis (VL), biceps femoris long head (BF), tibialis anterior (TA), gastrocnemius medial head (GM), and soleus (SOL) muscles at the following time points: pre (PRE), immediately post (POST), day-1 (D1), day-3 (D3), and day-8 (D8), after a full marathon...

BACKGROUND: The prevalence and severity of concomitant rotator cuff pathology in the setting of proximal biceps tendon ruptures are poorly understood. Concomitant rotator cuff disease may have important implications in the prognosis and natural history of this shoulder condition. Therefore, an observational cohort of patients with an acute rupture of the long head of the biceps tendon (LHBT) was evaluated to determine the prevalence and severity of concomitant rotator cuff disease. METHODS: Thirty consecutive patients diagnosed with acute proximal biceps tendon rupture were prospectively enrolled...

Purpose: To investigate the extent and evolution of hamstring muscle damage caused by an intensive bout of eccentric leg curls (ELCs) by (1) assessing the time course and association of different indirect markers of muscle damage such as changes in the force-generating capacity (FGC), functional magnetic resonance (fMRI), and serum muscle enzyme levels and (2) analyzing differences in the degree of hamstring muscle damage between and within subjects (limb-to-limb comparison). Methods: Thirteen male participants performed six sets of 10 repetitions of an ELC with each leg...

Arthroscopic repair of the long head of the biceps (LHB) is performed to treat various biceps pathologies yet the choice between tenotomy or tenodesis remains controversial. Although tenotomy is simpler and quicker, tenodesis results in fewer complications, and there are several techniques available using various fixation devices and sites. This Technical Note describes an all-arthroscopic, suprapectoral tenodesis technique using a bioresorbable interference screw, without motorized devices to create the humeral tunnel in the bicipital groove...

In the treatment of anterior shoulder instability, there are various conditions in which a sling effect is needed to enhance anterior stability. The traditional Latarjet procedure provides a sling effect but destroys the coracoacromial arch, which may result in superior instability. To preserve the coracoacromial arch and create a sling to enhance the anterior-inferior side of the shoulder, we introduce an arthroscopic technique to transfer the long head of the biceps (LHB) brachii. Indications of LHB transfer are patients younger than 45 years of age who participate in competitive sports, require forceful external rotation and abduction movement of the shoulder, and/or have capsule-ligament insufficiency, as well as patients 45 years o or older who have combined SLAP lesions (type II or IV)...

With a range of tear characteristics such as chronicity, degree of fatty atrophy, and number of tendons involved as well as varying patient-specific characteristics including age, injury mechanism, and expectations after treatment to consider, proper and successful treatment of a rotator cuff tear is multifactorial and, consequently, challenging. Although conservative management of a rotator cuff tear may be successful, a more severe tear with involvement of more tendons may warrant surgical intervention. Furthermore, additional pathology including biceps tendinopathy may result in greater patient morbidity and an even more complex treatment decision-making process and surgical technique...

INTRODUCTION: A "perineal" branch of the sciatic nerve has been visualized during surgery, but there is currently no description of this nerve branch in the literature. Our study investigates the presence and frequency of occurrence of perineal innervation by the sciatic nerve and characterizes its anatomy in the posterior thigh. MATERIALS AND METHODS: Fifteen cadavers were obtained for dissection. Descriptive results were recorded.Statistical analysis was performed and analyzed statistically...

Anterior cruciate ligament (ACL) injuries are a burdensome condition due to potential surgical requirements and increased risk of long term debilitation. Previous studies indicate that muscle forces play an important role in the development of ligamentous loading, yet these studies have typically used cadaveric models considering only the knee-spanning quadriceps, hamstrings and gastrocnemius muscle groups. Using a musculoskeletal modelling approach, we investigated how lower-limb muscles produce and oppose key tibiofemoral reaction forces and moments during the weight acceptance phase of unanticipated sidestep cutting...

Disorders of the long head of the biceps tendon (LHBT) are a common source of shoulder pain and disability. This tendon can be well visualized using ultrasonography; however, little is known if such examination allows clinicians to predict pathological changes of the tendon structure. In the study described below, we compare preoperative sonographic findings with the data from shoulder arthroscopy and microscopic examination of the excised tendon fragments in 19 consecutive patients with LHB tendinopathy and clinical suspicion of its instability...

The long head of the biceps (LHB) tendon is a potential source of shoulder pain encountered by orthopaedic surgeons. A multitude of approaches to addressing LHB tendinopathy have been described. These include various surgical techniques such as tenodesis versus tenotomy, an arthroscopic versus an open approach, and differing methods of tenodesis fixation. Our preferred approach to addressing LHB tendinopathy is through a mini-open approach using a double-loaded 4.5-mm suture anchor. This Technical Note with accompanying video describes our technique for performing this procedure, as well as supporting clinical evidence and technical pearls...

OBJECTIVE: The aim of a tenotomy of the long biceps tendon is to remedy a painful pathology in the proximal region of the tendon. Tenodesis of the tendon can restore the motor and cosmetic function of the biceps brachii muscle. INDICATIONS: Partial rupture or tendopathy of the long biceps tendon, injuries of the anchor of the long biceps tendon (SLAP lesions; SLAP: superior labrum anterior posterior), lesions of the pulley system. CONTRAINDICATIONS: Infections or tumors, loss of the long head biceps tendon from the intertubercular groove...

An irreparable cuff tear is defined as the inability to achieve direct repair of native tendon to the great tuberosity despite intra- and extra-articular release of the remaining tissue. Three distinct anatomic patterns are identified: posterosuperior cuff tears which involve the supraspinatus, infraspinatus and teres minor; anterosuperior tears which involve the supraspinatus and subscapularis; and global tears which comprise both. Subacromial debridement and tenotomy or tenodesis of the long head of the biceps are proposed for older patients with a functional but very painful shoulder...

PURPOSE: To investigate whether acute rupture of the proximal long head biceps is a harbinger of disease of the nearby supraspinatus and subscapularis tendons. METHODS: A retrospective chart review from February 1, 2008, to August 31, 2016, was performed at our institution identifying patients who presented with an acute (<12-week) history of "Popeye" deformity of the distal biceps and a magnetic resonance imaging (MRI) of the affected shoulder. MRI images were then reviewed in duplicate to determine supraspinatus and subscapularis tendon tear incidence, size, chronicity, and depth...
