Subacromial impingement syndrome results from irritation of the tendons of the rotator cuff muscles in the subacromial space and may manifest as a range of pathologies. However, subacromial impingement is a dynamic condition for which imaging reveals predisposing factors but no pathognomonic indicators. Also, the usual imaging features of subacromial impingement may be seen in symptomatic and asymptomatic patients.

Overhead athletes subject their shoulders to extreme repetitive torque, compression, distraction, and translation stresses, resulting in adaptive changes of the soft tissues and osseous structures within and around the glenohumeral joint. These anatomic adaptations result in biomechanical enhancements, which improve performance. Understanding the difference between necessary and adaptive changes and pathologic findings is critical when making treatment decisions.

The influence of preoperative rotator cuff fatty infiltration (FI) and muscle atrophy (MA) on the postoperative outcome of total shoulder arthroplasty (TSA) has only rarely been investigated and reported in the literature. We hypothesized that more FI and MA would be associated with a worse postoperative functional outcome.
This prospective cohort study included 63 patients (31 female and 32 male patients; mean age, 71 years [range, 53-89 years; standard deviation, 7 years]) with primary osteoarthritis of the shoulder operated on with anatomic stemless TSA.

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.

Shoulder instability after a posterior glenoid rim fracture is rare and potentially difficult pathology to treat. Operative techniques often involve a large dissection to view the fragments resulting in local soft tissue injury. Internal fixation is often achieved with interfragmentary screws; however, this may not be possible with small or multifragmentary fracture patterns.

Traditionally, initial management of first anterior shoulder dislocations consists of reduction of the glenohumeral joint followed by a period of immobilization and subsequent physical therapy to recover shoulder range of motion and strength. This traditional approach in management is now controversial due to the high rate of recurrence. The aim of this paper is to review and discuss the literature about the global management of patients presenting with first-time traumatic anterior glenohumeral dislocation, analyzing the factors that affect shoulder instability after the first episode of dislocation.

We present a computer-assisted planning solution "ArthroPlanner" for acromioplasty based on 3D anatomical models, computed tomography and joint kinematic simulations.
In addition to a standard static clinical evaluation (anamnesis, radiological examination), the software provides a dynamic assessment of the shoulder joint by computing in real time the joint kinematics from a database of activities of daily living. During motion, the precise bone resection (location and amount) is computed based on detected subacromial impingements, providing surgeons with precise information about the surgical procedure.

Arthroscopic techniques are an emerging technology to deal with glenoid bone defects in patients with anterior shoulder instability, and improvements are being made to safely minimize the risk of injury to the anterior neurovascular structures including the axillary nerve. Arthroscopic glenoid reconstruction is a technically demanding procedure, but it does have promising short-term outcomes. I truly like the concept of anterior (and also posterior) bone grafting for defects of the glenoid, including the arthroscopic Latarjet.

Ipsilateral phrenic nerve blockade is a common adverse event after an interscalene brachial plexus block, which can result in respiratory deterioration in patients with preexisting pulmonary conditions. Diaphragm-sparing nerve block techniques are continuing to evolve, with the intention of providing satisfactory postoperative analgesia while minimizing hemidiaphragmatic paralysis after shoulder surgery.
We report the successful application of a combined ultrasound-guided infraclavicular brachial plexus block and suprascapular nerve block in a patient with a complicated pulmonary history undergoing a total shoulder replacement.

The majority of musculoskeletal injuries located in the shoulder are often due to repetitive or sustained movements that occur in work routines in different areas. In the case of musicians, such as violinists, who have long and daily training routines, the repetitive movements they perform are forced and sometimes the postures are not natural. Therefore, this article aims to study and simulate the dynamic behavior of the glenohumeral joint under repetitive conditions that represent the different postures assumed by a violinist during his daily training.

Robotic stroke rehabilitation therapy can greatly increase the efficiency of therapy delivery. However, when left unsupervised, users often compensate for limitations in affected muscles and joints by recruiting unaffected muscles and joints, leading to undesirable rehabilitation outcomes. This paper aims to develop a computer vision system that augments robotic stroke rehabilitation therapy by automatically detecting such compensatory motions.

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.

Dislocation of the sternoclavicular joint is a rare injury and typically requires high-energy forces applied through the joint. Initial treatment is dependent on the direction of dislocation, with acute reduction indicated for posterior dislocations presenting with signs of tracheal, esophageal, or neurovascular compression. Although most patients do well with conservative treatment after the initial trauma, some can have persistent pain and scapular dyskinesia due to instability or locked dislocation of the sternoclavicular joint.

The armies of the North Atlantic Treaty Organization need a shoulder injury criterion for the EuroSID-2re dummy that must be reliable over a large range of loading conditions, from high velocity, short duration impacts (28 m/s - 3 ms) to low velocity long, duration impacts (4 m/s - 50 ms). In the literature, the human shoulder response to lateral impact was investigated at bounds of the loading condition spectrum as previously mentioned. For the low velocities, the injuries were mainly clavicle fractures and the maximum compression between the acromion and the sternum (Cmax) was proposed as an injury criterion.

The musculoskeletal configuration of the mammalian pectoral limb has been heralded as a key anatomical feature leading to the adaptive radiation of mammals, but limb function in the non-mammaliaform cynodont outgroup remains unresolved. Conflicting reconstructions of abducted and adducted posture are based on mutually incompatible interpretations of ambiguous osteology. We reconstruct the pectoral limb of the Triassic non-mammaliaform cynodont Massetognathus pascuali in three dimensions, by combining skeletal morphology from micro-computed tomography with muscle anatomy from an extended extant phylogenetic bracket.
