BACKGROUND: Traumatic hip dislocation in children and adolescents is a rare entity that typically results from high-energy trauma. After closed joint reduction, further treatment depends on the specific pattern of the lesion as identified using cross sectional imaging. The aim of this retrospective analysis was to evaluate relevant side effects after traumatic hip dislocation in children and adolescents in order to examine the need for focused diagnostics. PATIENTS/MATERIAL AND METHODS: This retrospective analysis covered 8 adolescents under 18 years suffering isolated traumatic hip joint dislocation between 2001 and 2017...

Traumatic glenohumeral dislocations often result in significant injury to the anterior-inferior labrum, most commonly leading to recurrent anterior instability. While in skeletally immature patients, shoulder trauma more commonly results in fracture versus a true dislocation, shoulder instability does occur and can be difficult to manage in the setting of open physes. In any event, the goal of treatment is to reduce the risk of recurrence and allow full participation in activities, including sports. Arthroscopic stabilization has been shown to be an effective treatment option for young patients, with good return to sport rates; however, the vast majority of literature on shoulder instability in the youth patient population focuses on anterior instability...

Traumatic hip dislocations constitute approximately 5% of all pediatric dislocations and typically result from high-energy trauma. However, pediatric hip dislocations can also occur as a result of minor energy due to flexibility of the joint structures of the immature hip. Children with a posteriorly dislocated hip present with the injured hip in flexion, adduction and internal rotation. Spontaneous relocation of hip dislocation is frequent and a thorough physical examination of the whole lower extremity is always required to reduce the chance of missing hip dislocation/subluxation...

The long head of the biceps tendon (LHBT) is a common source of pathology. The biceps-labral complex (BLC) is the collective anatomic and clinical features shared by the biceps tendon and the superior labrum. LHBT pathology can be caused by inflammation, instability, or trauma. Numerous tests can be performed to determine the existence of biceps tendon and superior labrum anterior to posterior (SLAP) lesions; however, many of these tests do not have high sensitivity and specificity, which limit their clinical utility...

➤Subtle forms of glenoid dysplasia may be more common than previously thought and likely predispose some patients to symptomatic posterior shoulder instability. Severe glenoid dysplasia is a rare condition with characteristic radiographic findings involving the posteroinferior aspect of the glenoid that often remains asymptomatic.➤Instability symptoms related to glenoid dysplasia may develop over time with increased activities or trauma. Physical therapy focusing on rotator cuff strengthening and proprioceptive control should be the initial management...

Labral pathologies of the glenohumeral joint are most commonly caused by trauma. The majority of lesions affect the anterior part of labrum, resulting from much higher frequency of anterior shoulder dislocations over posterior ones. Another subgroup of labral lesions, not directly related to joint instability, are SLAP tears. Other findings include degenerative changes of labrum and paralabral cysts. Diagnostic imaging is crucial for making a decision regarding operative treatment. Apart from a standard X-ray examination, the imaging mainly relies on magnetic resonance or computed tomography arthrography...

Rugby is a popular contact sport worldwide. Collisions and tackles during matches and practices often lead to traumatic injuries of the shoulder. This review reports on the epidemiology of injuries, type of lesions and treatment of shoulder injuries, risk factors, such as player position, and return to sport activities. Electronic searches through PubMed (Medline), EMBASE, and Cochrane Library retrieved studies concerning shoulder injuries in rugby players. Data regarding incidence, type and mechanisms of lesion, risk factors and return to sport were extracted and analyzed...

Surgical treatment of superior labral anterior posterior (SLAP) lesion becomes more and more frequent which is the consequence of evolving progress in both, imaging and surgical technique as well as implants. The first classification of SLAP lesions was described in 1990, a subdivision in four types existed. The rising comprehension of pathology and pathophysiology in SLAP lesions contributed to increase the types in SLAP classification to ten. Concerning the causative mechanism of SLAP lesions, acute trauma has to be differed from chronic degeneration...

BACKGROUND: Traumatic posterior hip dislocation in children is a rare injury that typically is treated with closed reduction. Surgical treatment is typically recommended for nonconcentric reduction with joint space asymmetry with entrapped labrum or an osteochondral fragment. The surgical hip dislocation (SHD) approach allows for full assessment of the acetabulum and femoral head and has been our preferred surgical strategy. The purpose of this study was to (1) describe the intra-articular pathologic findings seen at the time of SHD; and (2) to investigate hip pain, function, and activity level of a cohort of children and adolescents after open treatment of a posterior hip dislocation using the SHD approach...

OBJECTIVE: To investigate normal bony anatomy of the glenoid rim, to measure inner glenoid rim angle and outer glenoid rim angle, and the angles for successful anchor insertion for arthroscopic labral repairs. METHODS: Twelve unpaired isolated human glenoids (6 right, 6 left) without any evidence of trauma were for studying. The glenoid specimens were scanned using 320-slice CT (Aquilion ONE), then reconstruction glenoid to a three dimensional model using materialise's interactive medical image control system (Mimics) and to obtain cross-sectional images in 6 different planes, mark the right glenoid rim with clockwise tag, the left with counterclockwise tag...

The glenoid labrum is the fibrocartilage of the shoulder joint, anchoring the joint capsule and shoulder ligaments. Morphology varies regionally, especially in the superior and anterior region; these variants can sometimes be confused with pathological aspects. The labrum is often involved in shoulder pathology, by single trauma or, more often, repeated microtrauma. It seems logical to classify and to describe tears according to two criteria: the sector involved, and associated pain or instability. In the superior labrum, SLAP lesions are the most frequent...

Posterosuperior glenoid internal impingement (PGII) is an impingement syndrome of the shoulder that is most commonly seen in the throwing or overhead athlete. The supraspinatus can be normally compressed or impinged between the greater tuberosity and the posterosuperior labrum in the abduction and external rotation position. However, repetitive throwing and biomechanical abnormalities may lead to the intensification of this contact and to the clinical and pathological picture of PGII. The injured athlete usually complains of poor throwing performance and pain located in the posterosuperior aspect of the shoulder...

The anatomy of the shoulder joint comprises a relatively large humeral head with a shallow glenoid cavity allowing a remarkable range of motion at the expense of inherent instability. Despite anterior shoulder dislocations being the most common type encountered, bilateral dislocations are rare and almost always posterior. The aetiology is usually direct or indirect trauma related to sports, seizures, electric shock or electroconvulsive therapy. We present the first reported case of atraumatic bilateral acute anterior shoulder dislocations with associated Hill-Sachs lesions in a young, fit and well patient with no comorbidities...

Proximal humerus fractures comprise approximately 5% of all fractures, with isolated greater tuberosity fractures accounting for approximately 20% of proximal humerus fractures. Although performing shoulder arthroscopy in situations including a fracture is technically demanding, it allows surgeons the opportunity to identify and treat other coexisting lesions that could have otherwise been missed. The incidence of these pathologies in combination with greater tuberosity fractures has not been established. This study aimed to identify the various types of pathologies that may coexist with greater tuberosity fractures but not be detected before fixation...

The term "biceps brachii" is a Latin phrase meaning "two-headed (muscle) of the arm." As its name suggests, this muscle has two separate origins. The short head of biceps is extraarticular in location, originates from the coracoid process of the scapula, having a common tendon with the coracobrachialis muscle. The long head of biceps tendon (LBT) has a much more complex course, having an intracapsular and an extracapsular portion. The LBT originates from the supraglenoid tubercle, and in part, from the glenoid labrum; the main labral attachments vary arising from the posterior, the anterior of both aspects of the superior labrum (Bletran et al...

BACKGROUND: Some authors have described the ganglion cyst of the spinoglenoidal notch as related to repetitive overhead activities and labral tear caused by trauma, while others have explained lesions of the capsulolabral complex and ganglion cysts to have separate pathologies. The purpose of this study is to compare clinical and radiological outcomes between 2 groups: 1 with superior labrum anterior and posterior (SLAP) repair only and the other with SLAP repair and cyst decompression prospectively...
