Sternoclavicular joint anatomy

Wanpeng Li, Hongming Xu, Liming Zhao, Xiaoyan Li
BACKGROUND: Branchial anomalies (BAs) account for 20% of all congenital masses in children. We sought to review the incidence of involvement of individual anomalies, diagnostic methods, surgical treatment, and complications of BAs in children. In addition, we also classified our study and analyzed a congenital lower neck cutaneous fistula near the sternoclavicular joint that was thought to be the skin-side remnant of the fourth BAs. METHODS: We conducted a retrospective analysis of 105 children who were referred to our hospital from June 2009 to December 2016 for the treatment of BAs...

Chest wall ultrasound has been awarded little interest in the literature, with chest wall anatomy described only in limited extent. The objective of this study has been to discuss the methodology of chest wall ultrasound and the sonographic anatomy of the region to facilitate professional evaluation of this complex structure. The primarily used transducer is a 7-12 MHz linear one. A 3-5 MHz convex (curvilinear) transducer may also be helpful, especially in obese and very muscular patients. Doppler and panoramic imaging options are essential...

INTRODUCTION: Injuries to the medial clavicle in pediatric patients typically involve the physis and/or sternoclavicular joint. Clavicle fractures are one of the most common injuries in children, but ones at its medial end are rare. Most medial clavicle fractures are treated nonoperatively, but surgery is indicated in some cases. This original case report is unique in describing the use of an elastic intramedullary nail for fixation of a completely displaced medial clavicle fracture in a pediatric patient...

Chronic and acute shoulder pain and dysfunction are common complaints among patients. Shoulder pain may be the result of abnormality involving the rotator cuff, subacromial-subdeltoid bursa, biceps tendon, glenoid labrum, glenohumeral joint, acromioclavicular joint, sternoclavicular joint, or glenohumeral joint capsule. Ultrasound-guided (USG) procedures of the shoulder are well established for interventional management. Ultrasound provides the advantages of excellent soft tissue resolution, injection accuracy, low cost, accessibility, portability, lack of ionizing radiation, and the ability to perform real-time image-guided procedures...

BACKGROUND: The optimal location and extent of medial clavicle resection for sternoclavicular (SC) joint resection arthroplasty are unknown. HYPOTHESIS: Resection of the intra-articular disc alone cannot reliably decompress the SC joint, and a parallel resection technique will decompress the SC joint significantly more compared with the same amount with an oblique resection technique. STUDY DESIGN: Controlled laboratory study. METHODS: Force transmission through the SC joint was measured in 7 matched-pair human cadaveric SC joints in a dynamic tensile testing machine...

Dislocations of the sternoclavicular joint (SCJ) occur with relative infrequency and can be classified into anterior and posterior dislocation, with the former being more common. The SCJ is inherently unstable due to its lack of articular contact and therefore relies on stability from surrounding ligamentous structures, such as the costoclavicular, interclavicular and capsular ligaments. The posterior capsule has been shown in several studies to be the most important structure in determining stability irrespective of the direction of injury...

OBJECTIVE: The transradial catheterization (TRC) is becoming widespread, primarily for neurointerventions. Therefore, the evaluation of radial artery puncture in clinical practice and a better understanding of the anatomy are important to improve the safety of neuroendovascular surgery. METHODS: Ten formalin-fixed adult Korean cadavers were dissected to expose radial artery (RA), brachial artery (BrA) and subclvian artery (ScA), bilaterally. Vessel lengths and diameters were meaured using a caliper and distance between the specific point of vessels and the anatomical landmarks including the radial styloid process, the medial epicondyle of the humerus, the sternoclavicular joint, and the vertebral artery orifice were also measured...

Sternoclavicular joint dislocation is a rare event. It occurs most often in a violent trauma. The authors report the case of a10 years old child, received at emergencies for right shoulder blunt trauma after been punched by another child. He presented with right shoulder pain, right upper limb functional impairment and right sternoclavicular joint depression. Standard chest radiographs were normal. Chest CT scan showed posterior dislocation and allowed us to determine its variety. Twelve hours after the trauma, a closed reduction has been done under general anesthesia...

BACKGROUND: The quantitative anatomical relationships of the main ligamentous, tendinous, and osseous structures of the sternoclavicular joint have not been widely investigated. The purpose of this study was to provide a quantitative description of the sternoclavicular joint in relation to relevant surgical landmarks. METHODS: We dissected eleven nonpaired, fresh-frozen cadaveric sternoclavicular joints from four men and seven women (mean age at death, fifty-three years; range, thirty-three to sixty-four years) and measured the ligaments, musculature, and osseous landmarks with use of a three-dimensional coordinate-measuring device...

An otherwise healthy 45-year-old man presented to our emergency department holding his left arm in abduction and external rotation. He reported pain in his left shoulder and chest for the preceding 10 days that had become much worse over the last 48 h and was eased only by holding his arm in this position. The CT of the chest revealed soft tissue swelling around the left sternoclavicular joint consistent with sternoclavicular joint septic arthritis with significant inflammatory involvement of the medial component of the left pectoralis major muscle...

Professional rugby players are prone to traumatic thoracic injuries due to the use of minimal protective gear to cover the torso. In the 2007 Rugby World Cup, thoracic injuries occurred at a rate of 8.3 cases/1000 player-hours. CT and MRI play an important role in the diagnosis of these injuries. Vital internal organs, such as the heart, lungs, trachea, liver and large blood vessels lie within close proximity to the bony structures and what seems to be a simple rib fracture or clavicular dislocation can have potentially life-threatening complications that are not detected by conventional radiography...

Dissection studies revealed the fascicular anatomy of the trapezius. Its occipital and nuchal fibres passed downwards but mainly transversely to insert into the clavicle. Fibres from C7 and T1 passed transversely to reach the acromion and spine of the scapula. Its thoracic fibres converged to the deltoid tubercle of the scapula. Volumetric studies demonstrated that the fibres from C7, T1, and the lower half of ligamentum nuchae were the largest. The essentially transverse orientation of the upper and middle fibres of trapezius precludes any action as elevators of the scapula as commonly depicted...

The sternoclavicular joint (SCJ) is a pivotal articulation in the linked system of the upper limb girdle, providing load-bearing in compression while resisting displacement in tension or distraction at the manubrium sterni. The SCJ and acromioclavicular joint (ACJ) both have a small surface area of contact protected by an intra-articular fibrocartilaginous disc and are supported by strong extrinsic and intrinsic capsular ligaments. The function of load-sharing in the upper limb by bulky periscapular and thoracobrachial muscles is extremely important to the longevity of both joints...

Pathologies of the sternoclavicular (SC) joint are infrequent and effective management is often hindered by a limited understanding of the anatomy. In this study, we did macroscopic evaluations of the ligaments, the intra-articular disc, and the articulating surfaces of 25 SC joints. After removal of the joint capsule, the articulating surfaces of the sternal end of clavicle and the sternum were evaluated and the intra-articular disc was macroscopically examined. The anterior SC ligament covered the intra-articular disc, which divided the joint into a clavicular and a sternal part...

OBJECTIVES: To describe the plane of the sternoclavicular joint (SCJ) to aid planning of instrument orientation during invasive procedures. METHODS: Computed tomography (CT) images of 80 consecutive patients aged 25 to 40 years with appropriate chest imaging series were retrospectively reviewed. Patients with a previous median sternotomy, fused manubriosternal joint or fracture were excluded. The medial clavicle was found to vary greatly in its anatomy such that a representative morphology could not be described...

BACKGROUND: Dislocation of the sternoclavicular joint is rare. However, posterior dislocation compressing important structures in the mediastinum may be fatal. Early diagnosis and prompt therapy of sternoclavicular joint dislocation are important. Computed tomography (CT) is an optimal means to investigate sternoclavicular joint anatomy; however, there are few reports on the imageological anatomical features of the sternoclavicular joint. The study investigated imageological anatomical features, and a new plate was devised according to these data to treat sternoclavicular joint dislocation...

Temporomandibular joint (TMJ) ankylosis is characterized by difficulty or inability to open the mouth due to fusion of the temporal and the mandible, resulting in facial symmetry/deformity, malocclusion and dental problems. The only treatment option for TMJ ankylosis is surgical with or without condylar reconstruction. Various autogenous grafts are available for condylar reconstruction after freeing the ankylotic mass such as costochondral, sternoclavicular, fibular, coronoid, and metatarsophalangeal. Costochondral graft is preferred by surgeons, but distraction osteogenesis is slowly gaining popularity and may ultimately become the standard procedure, providing a cost-effective approach with low morbidity and excellent functional outcomes...

Dislocation of the sternoclavicular joint (DSCJ) with posterior displacement of the clavicle is uncommon in children. This can lead to ipsilateral compression of the great vessels. Diagnosis may not be apparent on routine radiographs. Axial computed tomographic (CT) scan is the imaging of choice for diagnosis. Reconstruction and 3-dimensional (3D) views on CT scan may be helpful to define the anatomy before surgical reduction. We present 2 patients who had traumatic posterior DSCJ with compromise to their vascular structures...
