BACKGROUND AND PURPOSE: The dislocation of mandibular condyle is a clinical condition in which the head of condyle has been displaced out of the glenoid fossa. Complete dislocation of the mandibular condyle can occur in anterior, posterior, lateral and superior direction. Among these dislocations, bilateral superolateral dislocation of mandibular condyles is quite rare and often misdiagnosed. Because of its rare occurrence and unusual clinical course, the best treatment is debatable. PATIENTS AND METHOD: We present the first case series of true bilateral superolateral dislocation of intact mandibular condyles (Type 2B) without fracturing the Zygomatic arch, associated with symphysis fracture...

The goal of this study was to describe an internal fixation technique for periprosthetic humeral fractures using a cortical onlay strut allograft stabilized with cerclage wires and to evaluate the preliminary results of this approach. An anterolateral approach was used to direct access the fracture and to protect the radial nerve. The fracture was reduced with two forceps, under visual control. The fracture was surrounded by two hemicylinder tibial allografts, placed around the humerus with no prior reaming to create a "sarcophagus" system...

An articular glenoid fracture is an uncommon injury. Usually significantly displaced intra-articular glenoid fractures are treated with open reduction surgery. Conventional open surgery techniques involve high morbidity. Here we describe an arthroscopy-assisted reduction and fixation method of an Ideberg type III glenoid fracture. This method provides good articular reduction without extensive exposure or soft tissue dissection and without nerve and/or vascular lesion.

BACKGROUND: A combined fracture of the glenoid rim, greater tuberosity, and coracoid process after anterior shoulder dislocation is a rare event. Only 1 patient has been reported in the literature. METHODS: All patients with a first-time traumatic anterior shoulder dislocation in a level A trauma center were retrospectively reviewed. Among the 2068 patients treated between 1998 and 2013, we identified 6 patients (0.3%; 1 female, 5 male) with "triple dislocation fracture" (anterior shoulder dislocation with concomitant fracture of the glenoid rim, greater tuberosity, and coracoid process)...

BACKGROUND: In a previous biomechanical study, eccentric glenospheres with more inferior position of the center of rotation were shown to improve range of motion and reduce the incidence of scapular notching after reverse total shoulder arthroplasty (RSA). The purpose of this study was to compare the clinical and radiological results of RSA using an eccentric glenosphere to those using a concentric glenosphere and to determine the usefulness of the eccentric glenosphere. METHODS: From 2009 to 2015, we performed a retrospective review of 20 consecutive patients who underwent RSA using a deltopectoral approach...

An osseous Bankart lesion is commonly seen in patients with an anterior shoulder dislocation. It is defined as a detachment of the anteroinferior labrum associated with a glenoid rim fracture. Radiological studies are crucial not only for detecting glenoid bone defects but also for measuring the amount of bone loss. The precise quantification of the bony defect is crucial for the therapeutic desicion-making and clinical outcomes. Although we know that major glenoid bone loss requires surgical intervention, none of the studies performed so far answered the question what size of the defect should be an indication for open surgery procedures...

INTRODUCTION: Calcifying tendinitis of the shoulder is characterized with the formation of the calcium deposits in tendon, which mostly involves supraspinatus. The formation of the calcium deposits may be related to the excessive mechanical stimulation and non-tenocytes generation from tendon stem cell. The disease is usually associated with pain, especially when activating the shoulder. MATERIALS AND METHODS: We describe one case of calcifying tendinitis involving the long head of the biceps brachii and superior labrum...

Temporomandibular joint replacement (TJR) with alloplastic prosthesis has shown promising long-term results in end stage joint disorders. We present a case of young woman with painful ankylosis that where reconstructed with TJR, due to a complex mandibular fracture with dislocation of the left condyle into the middle cranial fossa two years earlier. At the age of 18 the subject underwent a total joint replacement with custom-made alloplastic TMJ prosthesis. To determine the bone response and remodeling activity around the prosthesis, a F18 PET/CT-scan was used...

BACKGROUND: Increased operative duration has been shown to have demonstrable effects on the outcomes and complications in multiple areas of orthopedic surgery. We sought to determine if patient- and surgeon-specific factors correlated to operative duration in shoulder arthroplasty. Our hypothesis was that increased surgeon and trainee volume would decrease operative times and that more complex pathology would increase operative duration. METHODS: A retrospective review of primary and revision total and reverse shoulder arthroplasties performed at a single institution from 2012 through 2015 was performed evaluating the correlation between specific patient and surgeon factors and operative duration...

BACKGROUND: Reverse total shoulder arthroplasty (RTSA) is a viable treatment option for rotator cuff tear arthropathy but carries a complication risk of scapular fracture. We hypothesized that using screws above the central glenoid axis for metaglene fixation creates a stress riser contributing to increased scapula fracture incidence. Clinical type III scapular fracture incidence was determined with screw placement correlation: superior screw vs. screws placed exclusively below the glenoid midpoint...

Large glenoid fractures are relatively uncommon with shoulder dislocation. Simultaneous glenoid and greater tuberosity fractures with anterior shoulder dislocation are very rare. We report on a 48-year right-handed male who sustained a fall during skiing. He had anterior shoulder dislocation combined with large glenoid fracture and greater tuberosity fracture. He was treated surgically with fixation of the glenoid and greater tuberosity fractures, using two different approaches. The deltopectoral approach with coracoid osteotomy and subscapularis split was used for glenoid fixation...

Intramedullary nailing for stabilization of proximal humeral fractures is well-established. Complications as part of a cut-through, such as backing out of locking screws, loss of reduction, and perforation of the screws into the glenoid, are equally well-known. The test bench presented in this study enables testing of the cut-through behavior of multiple intramedullary implants on a simulated osteoporotic three-part fracture configuration with three different loading circumstances (A, B and C). In situation A, the glenohumeral dynamic force with progressive loadings entered at an angle of 15° to the humeral shaft...

Recurrent anterior shoulder instability following shoulder dislocation has an incidence as high as 68% among the younger population, however its association with coracoid fracture is extremely rare. Majority of coracoid fractures reported earlier have been shown to be associated with seizure disorder. We report a case of displaced coracoid fracture associated with recurrent anterior instability in a patient with no history of seizure disorder and its implications in causation as well as management are discussed...
