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...

OBJECTIVE: Shoulder stabilization. INDICATIONS: Symptomatic recurrent anterior shoulder instability combined with glenoid bone loss of approximately 20-35 % of the glenoid surface, engaging Hill-Sachs lesion and/or previously failed arthroscopic Bankart repair. In patients with a high risk of redislocation (contact sports) or irreparable soft tissue injury the Latarjet procedure can be considered as a first-line treatment. CONTRAINDICATIONS: Contraindicated if arthroscopic Bankart repair is possible...

BACKGROUND: The prevalence of combined humeral and glenoid defects varies between 79 and 84 % in case of chronic posttraumatic anterior shoulder instability. The main goal of this study was to evaluate the relationship between humeral and glenoid defects based on quantitative radiological criteria. METHODS: A retrospective study was performed between 2000 and 2011 including patients who underwent primary surgical shoulder stabilization for chronic posttraumatic anterior shoulder instability, with bone defects in both the glenoid and humerus and a healthy contralateral shoulder...

: Management of a posterior shoulder dislocation with an associated reverse Hill-Sachs lesion is challenging, both diagnostically and therapeutically. Diagnosis is frequently delayed or missed, whereas the resulting humeral head defect is often larger and more difficult to salvage than in anterior shoulder dislocations. This report presents the case of a 29-year-old male with a recurrent posterior shoulder dislocation associated with a large reverse Hill-Sachs defect, treated with bone augmentation of the lesion with a combination of fresh femoral head allograft and a locally harvested humeral head autograft transfer, with a successful outcome...

Management of the unstable shoulder after a failed stabilization procedure can be difficult and challenging. Detailed understanding of the native shoulder anatomy, including its static and dynamic restraints, is necessary for determining the patient's primary pathology. In addition, evaluation of the patient's history, physical exam, and imaging is important for identifying the cause for failure after the initial procedure. Common mistakes include under-appreciation of bony defects, failure to recognize capsular laxity, technical errors, and missed associated pathology...

INTRODUCTION: Neglected bilateral anterior shoulder dislocation is a very rare condition, often related to seizures or major trauma. Open reduction is recommended whenever Hill-Sachs lesion is >25% of the joint and the dislocation is elder than 3 weeks. CASE REPORT: We describe a case report of a 28-year-old man left handed Jehovah's Witness laborer assessed 12 weeks after bilateral anterior shoulder dislocation. The patient was evaluated with clinical examination, and it was observed an asymptomatic intrarotation of both shoulders with a mild left circumflex nerve deficit...

BACKGROUND: The effect of osteoallograft repair of a Hill-Sachs lesion and the effect of allograft fit on glenohumeral translations in response to applied force are poorly understood. PURPOSE: To compare the impact of a 25% Hill-Sachs lesion, a perfect osteoallograft repair (PAR) of a 25% Hill-Sachs lesion, and an "imperfect" osteoallograft repair (IAR) of a 25% Hill-Sachs lesion on glenohumeral translations in response to a compressive load and either an anterior or posterior load in 3 clinically relevant arm positions...

BACKGROUND: The Latarjet procedure for the treatment of recurrent anterior shoulder instability is highly successful, but reasons for failure are often unclear. Measurements of the "glenoid track" have not previously been evaluated as potential predictors of postoperative stability. HYPOTHESIS: There are clinical and anatomic characteristics, including the glenoid track, that are predictive of outcomes after the Latarjet procedure. STUDY DESIGN: Case series; Level of evidence, 4...

PURPOSE: To study the degree of surface congruency between the talar dome and humeral head, to determine the size of graft harvestable from the talar dome, and to determine if there are surrogate markers that correspond to a higher degree of surface congruency. METHODS: Computer models of 7 nonmatched humeral heads and 7 talar domes were generated by digital segmentation of magnetic resonance (MR) images. Modeled defect regions of each humeral head were then aligned with medial and lateral surfaces of each talar dome using software to maximally limit surface mismatch...

PURPOSE: To evaluate the effect of "off-track" Hill-Sachs lesions, according to the glenoid track concept, as a risk factor for recurrent instability and need for revision surgery after arthroscopic Bankart repair. METHODS: We retrospectively reviewed 254 patients with anteroinferior glenohumeral instability who were managed with an arthroscopic stabilization procedure between 2006 and 2013. Preoperative magnetic resonance imaging and/or computed tomography scans were available for 100 of these patients to calculate the glenoid track and the presence of "on-track" or off-track Hill-Sachs lesions...

BACKGROUND: Recurrent glenohumeral instability is often a result of underlying bony defects in the glenoid and/or humeral head. Anterior glenoid augmentation with a coracoid bone block (ie, Latarjet procedure) has been recommended for glenoid bone loss in the face of recurrent instability. However, no study has investigated the effect of Latarjet augmentation in the setting of both glenoid and humeral head defects (Hill-Sachs defects). PURPOSE: To evaluate the glenohumeral kinematics of the Latarjet procedure in the presence of combined bony defects...
