BACKGROUND: The acromioclavicular (AC) capsule is an important stabilizer against horizontal translation and also contributes to the strut function of the clavicle, which guides rotation of the scapula. To best reproduce the biomechanical properties and the complex 3-dimensional (3D) guidance of the AC joint, detailed knowledge of the contribution of each of the distinctive capsular structures is needed. Purpose/Hypothesis: To perform a detailed biomechanical evaluation of the specific capsular structures of the AC joint and their contribution to translational and rotational stability...

BACKGROUND: Suspension suture button fixation was frequently used to treat acromioclavicular joint (ACJ) dislocation. However, there were many studies reporting about complications and residual horizontal instability after fixation. Our study compared the stability of ACJ after fixation between coracoclavicular (CC) fixation alone and CC fixation combined with ACJ repair by using finite element analysis (FEA). MATERIALS AND METHODS: A finite element model was created by using CT images from the normal shoulder...

Acromioclavicular dislocation is a frequent pathology commonly encountered in traumatology. Therefore, its management is generally standardized, guided by clinical and radiological evaluation. This can range from conservative treatment by limb immobilization and functional rehabilitation, to surgical treatment by using minimally invasive techniques. We present the particular case of a 74-year-old patient with an acromioclavicular dislocation associated with a non-displaced fracture of the coracoid process as well as of the spine of the scapula...

Injuries to the acromioclavicular joint and coracoclavicular ligaments are common. Many of these injuries heal with nonoperative management. However, more severe injuries may lead to continued pain and shoulder dysfunction. In these patients, surgical techniques have been described to reconstruct the function of the coracoclavicular ligaments to provide stable relationship between the clavicle and scapula. These surgeries have been fraught with high complication rates including clavicle and coracoid fractures, infection, loss of reduction and fixation, hardware migration, and osteolysis...

Office-based ultrasonography has become increasingly available in many settings, and its use to guide joint and soft tissue injections has increased. Numerous studies have been conducted to evaluate the use of ultrasound-guided injections over traditional landmark-guided injections, with a rapid growth in the literature over the past few years. A comprehensive review of the literature was conducted to demonstrate increased accuracy of ultrasound-guided injections regardless of anatomic location. In the upper extremity, ultrasound-guided injections have been shown to provide superior benefit to landmark-guided injections at the glenohumeral joint, the subacromial space, the biceps tendon sheath, and the joints of the hand and wrist...

BACKGROUND: A magnetic resonance imaging (MRI) scan of the shoulder can have added value in diagnosing symptomatic osteoarthritis of the acromioclavicular (AC) joint. Specific MRI signs have been recognized but not analyzed extensively before. This study aims to identify predictive MRI signs in patients with symptomatic AC osteoarthritis. METHODS: The MRI scans of 70 patients with symptomatic AC osteoarthritis were compared with those of 70 patients with subacromial pain syndrome and no clinical signs of symptomatic AC osteoarthritis...

BACKGROUND: The purpose of this study is to analyze the 3-dimensional scapular dyskinesis and the kinematics of a hook plate relative to the acromion after hook-plated acromioclavicular dislocation in vivo. Reported complications of acromioclavicular reduction using a hook plate include subacromial erosion and impingement. However, there are few reports of the 3-dimensional kinematics of the hook and scapula after the aforementioned surgical procedure. METHODS: We studied 15 cases of acromioclavicular dislocation treated with a hook plate and 15 contralateral normal shoulders using computed tomography in the neutral and full forward flexion positions...

BACKGROUND: An anatomic double-tunnel (DT) reconstruction technique has been widely adopted to reconstruct the ruptured coracoclavicular (CC) ligaments seen with high-grade acromioclavicular (AC) joint injuries. However, the anatomic DT reconstruction has been associated with the risk of clavicle fractures, which may be problematic, particularly for contact athletes. Purpose/Hypothesis: The purpose was to compare a single-tunnel (ST) CC ligament reconstruction for AC joint injuries with the native state as well as with the more established anatomic DT CC ligament reconstruction...

Acromioclavicular (AC) joint injuries are common and often seen in contact athletes, resulting from a fall on the shoulder tip with adducted arm. This joint is stabilized by both static and dynamic structures including the coracoclavicular (CC) ligament. Most reconstruction techniques focus on CC ligament augmentation as the primary stabilizer of the AC joint. The best surgical technique for some AC joint dislocations is still controversial. In this study, we explained a modification of the CC ligament reconstruction technique described by Wellmann...

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...

BACKGROUND: Several techniques have been introduced to treat acromioclavicular (AC) separation using the semitendinosus tendon as a graft for coracoclavicular (CC) ligament reconstruction. However, the tendon may have been used previously or the patient may not want it harvested. Hence, synthetic tendon transfers have become increasingly popular. METHODS: Five patients with chronic AC separations were treated. A synthetic polyurethane urea tendon graft (Artelon Tissue Reinforcement [ATR]) was chosen for its ability to partially transform into connective tissue...
