BACKGROUND: Recurrence of glenohumeral dislocation after arthroscopic Bankart repair can be associated with a large osseous defect in the posterosuperior part of the humeral head. Our hypothesis is that remplissage is more effective to prevent recurrence of glenohumeral instability without a severe motion deficit. METHODS: Engaging Hill-Sachs lesions were observed in 48 of 737 patients (6.5%). Twenty-four patients underwent arthroscopic Bankart repair combined with remplissage (group I) and the other 24 patients underwent arthroscopic Bankart repair alone (group II)...

Humeral bone loss has been shown to be a risk factor for failure after arthroscopic treatment of instability. We present the arthroscopic remplissage technique originally described by Koo and Burkhart et al. with a modification in the percutaneous anchor placement and suture tying that is reproducible and effective. We percutaneously place 2 suture anchors, which require no additional suture passing across the tissue, to create a double pulley technique, filling the defect with posterior capsule and rotator cuff...

PURPOSE: To assess the short-term outcomes of the arthroscopic subscapularis augmentation (ASA) technique, consisting of a tenodesis of the upper third of the subscapularis tendon and a Bankart repair, and its effect on shoulder external rotation. METHODS: Patients selected for this study were involved in contact sports, with a history of traumatic recurrent shoulder dislocations and a minimum of 2-year follow-up. Inclusion criteria were patients with glenoid bone loss (GBL) ranging from 5% to 25%, anterior capsular deficiency, and Hill-Sachs lesion who underwent ASA technique...

BACKGROUND: Glenoid and humeral bone loss are well-described risk factors for failure of arthroscopic shoulder stabilization. Recently, consideration of the interactions of these types of bone loss (bipolar bone loss) has been used to determine if a lesion is "on-track" or "off-track." The purpose of this study was to study the relationship of the glenoid track to the outcomes of arthroscopic Bankart reconstructions. METHODS: Over a 2-year period, 57 shoulders that were treated with an isolated, primary arthroscopic Bankart reconstruction performed at a single facility were included in this study...

Posterior Hill-Sachs humeral defects are present in 80% to 100% of cases of anterior shoulder dislocation and are a factor in recurrent instability. Several techniques have been described to fill the defect and avoid recurrence. We developed a percutaneous technique to fill the newly created defect in which a percutaneous balloon, analogous to the one used in vertebral kyphoplasty, is used to reduce the defect, which is then filled with calcium phosphate cement. One patient with an acute anterior dislocation of the shoulder with no previous history was treated using this method...

A neglected shoulder dislocation is a rarer entity and only few cases are reported in the literature. An anterior dislocation of the shoulder is rarely missed as patients present with limb in abduction and external rotation, an attitude very familiar to orthopaedic surgeon. Occasionally such cases are missed when they present with fracture of proximal humerus or when they receive treatment from unqualified practitioners who commonly practise in rural areas. Owing to very few reports there is paucity of literature and no standard treatment protocol exists for neglected anterior dislocation of the shoulder, though most such chronic cases are managed by open reduction...

BACKGROUND: Although recurrent anterior shoulder instability (RASI) is a common condition in young patients, no studies to date have measured the 3-dimensional (3D) locked position of the glenohumeral joint during an anterior dislocation. Therefore, our goal was to estimate it with 3D computed tomography (CT) scans. METHODS: Patients in this prospective observational study were separated in 3 groups: normal laxity, hyperlaxity, and epilepsy. They were characterized by questionnaires (Western Ontario Shoulder Instability Index, 11-item version of the Disabilities of the Arm, Shoulder and Hand, and Beighton Laxity Score), and a CT scan revealing bipolar bone defects...

BACKGROUND: The purpose of the present study was to evaluate the results of the Sheffield bone block procedure for anteroinferior bone loss in traumatic shoulder instability. In this modified open technique, the medial half of coracoid process without its soft tissue attachments is used to provide congruent augmentation of the anteroinferior glenoid and secured with two screws. METHODS: In this retrospective consecutive case series (2007-11), all patients having recurrent traumatic instability with glenoid bone loss > 20% and/or a large Hill-Sachs lesion were included...

BACKGROUND: Among the uncommon and frequently missed orthopedics injuries is the posterior shoulder dislocation, accounting for about 2-4 % of all shoulder dislocations. Commonly, it is associated with the well-known reverse Hill-Sachs lesion. Several surgical treatment modalities such as transfer of subscapularis tendon or lesser tuberosity, humeral rotational osteotomy, osteochondral grafts were used to repair this defect. Hemiarthroplasty or total shoulder arthroplasty was used as salvage procedure in non-constructable defect or neglected old dislocation...

The inherently unstable anatomy of glenohumeral (GH) joint predisposes it to shoulder dislocation. Shoulder dislocation can occur either due to acute trauma or due to chronic microtraumas in the setting of underlying morphological abnormality. A plain radiograph is the initial imaging modality for diagnosis and management of shoulder dislocation and its associated osseous abnormalities such as Hill-Sachs deformity or osseous Bankart lesion. However, advanced imaging techniques such as multidetector CT (MDCT) with three-dimensional (3D) volume rendering and MRI can be helpful in further characterization of osseous abnormalities and detection of associated soft tissue injuries, respectively...

BACKGROUND: Anatomic studies have demonstrated that bipolar glenoid and humeral bone loss have a cumulative effect on shoulder instability and that these defects may engage in functional positions depending on their size and location, potentially resulting in failure of stabilization procedures. Determining which lesions pose a risk for engagement remains challenging, with arthroscopic assessments and a 3-dimensional computed tomography (CT)-based glenoid track method being accepted approaches at this time...

BACKGROUND: Abnormal glenoid version is a risk factor for shoulder instability. However, the degree to which the variance in version (both anteversion and retroversion) affects one's predisposition for instability is not well understood. PURPOSE: To determine the influence of glenoid version on anterior shoulder joint stability and to determine if the direction of the humeral head dislocation is a stimulus for the development of Hill-Sachs lesions. STUDY DESIGN: Controlled laboratory study...

The patient was a 21-year-old collegiate running back who was tackled during a football game and sustained a posterior glenohumeral dislocation. He was referred to an orthopaedist and presented 3 weeks after the injury, and, following examination, further imaging was ordered by the orthopaedist due to rotator cuff weakness. Magnetic resonance imaging showed a complete tear of the supraspinatus and infraspinatus, as well as a posterior Bankart lesion, a subscapularis tear, and a dislocation of the biceps long head tendon into the reverse Hill-Sachs lesion...

The patient was a 61-year-old woman who underwent long-lever manipulation under anesthesia (MUA) for adhesive capsulitis. Two weeks following MUA, the constellation of clinical findings raised concern for possible adverse outcomes. Radiographs were obtained, as well as subsequent magnetic resonance imaging and computed tomography scans. Images revealed anterior shoulder dislocation with Bankart and Hill-Sachs lesions, and an anterior rotator cuff tear. J Orthop Sports Phys Ther 2016;46(8):707. doi:10.2519/jospt...

BACKGROUND: Patients who suffer anterior shoulder dislocations are at higher risk of developing glenohumeral arthropathy, but little is known about the initial cartilage damage after a primary shoulder dislocation. T1ρ is a magnetic resonance imaging (MRI) technique that allows quantification of cartilage proteoglycan content and can detect physiologic changes in articular cartilage. PURPOSE: This study aimed to establish baseline T1ρ MRI values for glenoid and humeral head cartilage, determine whether T1ρ MRI can detect glenohumeral cartilage damage after traumatic primary shoulder dislocation, and assess for patterns in cartilage damage in anterior shoulder dislocation...

PURPOSE: To validate the glenoid track concept in a cadaveric bipolar bone loss model and to test whether "on-track" and "off-track" lesions can be stabilized with Bankart repair (BR) with or without Hill-Sachs remplissage (HSR). METHODS: Eight fresh-frozen cadaveric shoulders were tested in a custom apparatus with passive axial rotation and then progressive translational loading (10 to 40 N) at mid-range (60°) and end-range external rotation (90°). Injury conditions included glenoid bone loss of 15% with on-track (15%) and off-track (30%) Hill-Sachs lesions...
