HYPOTHESIS: The objective of the study was to evaluate the development of scapular notching in reverse shoulder arthroplasty by comparing larger glenospheres (42 mm) with smaller glenospheres (38 mm). METHODS: This was a prospective randomized study of 81 patients who had undergone reverse shoulder arthroplasty with a 2-year follow-up. Patients were randomized to receive either a 42-mm glenosphere (38 patients) or a 38-mm glenosphere (43 patients). Scapular notching development was assessed with an anteroposterior radiograph at the end of the follow-up...

BACKGROUND: Plain radiographs still play a role in management of extraarticular scapular neck fractures. Glenopolar angle (GPA) is one of the radiograph measurements that is used to determine the necessity for surgery. Our aim was to establish reliability of GPA on plain radiograph in patients with extraarticular scapular neck fractures. METHODS: We performed a multicentre retrospective study including all patients with extraarticular scapular neck fractures with available imaging between 2006 and 2012...

BACKGROUND: Treatment of post-resective defects of the maxilla can be challenging and usually requires dental obturation or microvascular reconstruction. As compared to soft-tissue microvascular grafts, bone reconstruction can additionally allow for facial support and retention of dental implants. The aim of this study was to evaluate scapular tip grafts with respect to their applicability for maxillary reconstruction and their potential to retain dental implants for later dental rehabilitation...

BACKGROUND: Glenoid retroversion may accelerate glenoid loosening after total shoulder arthroplasty. Accurate measurement of preoperative glenoid deformity is critical for decision-making and prognostication. The purpose of this study was to determine whether glenoid version, inclination, and depth and humeral subluxation measurements on computed tomography (CT) scan slices oriented in the plane of the body differ from those oriented in the scapular plane and those obtained by automated 3-dimensional reconstruction software in the setting of a biconcave B2-type glenoid...

Acromial and scapular spine fractures after reverse total shoulder arthroplasty occur predominantly as a result of bony insufficiency secondary to patient and intra-operative technical factors. The spectrum of the pathology can range from a stress reaction to an undisplaced or displaced fracture. Prompt diagnosis of these fractures requires a high suspicion in the postoperative patient with a clinical presentation of acute onset of pain along the acromion or scapular spine and/or deterioration of shoulder function...

BACKGROUND: The treatment of fracture sequelae of the proximal part of the humerus in combination with posttraumatic arthritis is challenging. The reported results of treatment with anatomic shoulder arthroplasty are disappointing. The aim of this multicenter study was to analyze the clinical and radiographic results of reverse shoulder arthroplasty for treatment of posttraumatic sequelae of the proximal part of the humerus with malunion of the tuberosities. METHODS: This was a retrospective, multicenter study of 42 patients (42 shoulders) with the diagnosis of posttraumatic sequelae of the proximal part of the humerus with malunions of the tuberosities who were treated with reverse shoulder arthroplasty between 2000 and 2010...

Glenoid dysplasia is a developmental anomaly of the scapula that is characterized by a bony deficiency of the posteroinferior glenoid and the adjacent scapular neck. Glenoid dysplasia may occur as a primary isolated condition or in association with various syndromes. It is thought to be related to defective ossification of the inferior glenoid precartilage. Radiographs typically demonstrate bilateral, symmetric dysplasia of the scapular neck with a range of associated bony changes. Glenoid dysplasia has been associated with instability and premature glenohumeral arthritis, although the clinical presentation is highly variable...

BACKGROUND: Large glenoid defects pose difficulties in shoulder arthroplasty. Structural grafts consisting of a humeral head autograft, iliac crest, and allograft have been described. Few series describe grafts used with reverse total shoulder arthroplasty (RTSA). METHODS: We retrospectively reviewed patients who had undergone primary or revision RTSA. We identified 44 patients (20 men and 24 women; mean age, 69 years) as having a bulk structural graft to the glenoid behind the baseplate...

BACKGROUND: Convention dictates that an axillary view be obtained when evaluating proximal humerus fractures (PHF). However, the axillary view is frequently omitted because of pain and technical considerations. Furthermore, its diagnostic utility is unclear in this setting. QUESTIONS/PURPOSES: The purpose of this study was to (1) determine the rate of obtaining an adequate axillary X-ray and complete shoulder series at a level I trauma center, (2) understand the cost of ordering and attempting an axillary radiograph, and (3) determine if axillary radiographs influence the management of PHF...

Fibrodysplasia Ossificans Progressiva (FOP) is a rare autosomal dominant disorder characterized by postnatal progressive heterotopic ossification of connective tissue and congenital malformation of big toes. We report a 3-year male toddler with clinical and radiological features of FOP. He was born with bilateral hallux valgus and at the age of 3 years presented with hard swellings over back, scapular region and forehead that were initially inflammatory and then became bony hard. There is also tilting of neck towards the left due to calcification in neck region...

The purpose of this study was to investigate the effects of a 6-week scapular upward rotation exercise (SURE) on scapular and clavicular alignment and scapular upward rotators strength in subjects with scapular downward rotation syndrome (SDRS). Seventeen volunteer subjects with SDRS were recruited from university populations. The alignment of the scapula and clavicle was measured using radiographic analysis and compared in subjects before and after a 6-week self-SURE program. A hand-held dynamometer was used to measure the strength of the scapular upward rotators...

BACKGROUND: Total shoulder arthroplasty has been shown to improve function and to reduce pain in cases of osteoarthritis. To assess loosening of the glenoid component, serial evaluation of frontal plane radiographs of the scapula has been established as the "gold standard." The aim of this study was to evaluate the reliability of different bone landmarks when the scapula is tilted compared with the ideal view. METHODS: Glenoid components were implanted into 6 human cadaveric scapulae...

BACKGROUND: Current evidence suggests that distinct scapular morphologies may predispose patients to a rotator cuff tear. The objective of this longitudinal study was to evaluate the relationship between symptomatic degenerative cuff tears and different radiographic acromial characteristics, including acromion shape, indices (acromial index [AI], critical shoulder angle [CSA]), and acromial spur. METHODS: We divided 166 patients into 3 groups matched for age and sex: group 1, degenerative full-thickness tear; group 2, partial thickness bursal tear; and group 3, normal cuff...

Measures of scapulothoracic motion are dependent on accurate imaging of the scapula and thorax. Advanced radiographic techniques can provide accurate measures of scapular motion, but the limited 3D imaging volume of these techniques often precludes measurement of thorax motion. To overcome this, a thorax coordinate system was defined based on the position of rib pairs and then compared to a conventional sternum/spine-based thorax coordinate system. Alignment of the rib-based coordinate system was dependent on the rib pairs used, with the rib3:rib4 pairing aligned to within 4...

UNLABELLED: Scapular fractures are still a challenge in traumatology of the musculoskeletal apparatus. Their proper understanding is impossible without fundamental anatomical and clinical knowledge. A considerable part of scapular fractures is associated with other severe injuries, particularly to the chest. Essential for diagnosis and treatment of these fractures is radiographic examination, primarily both Neer projections and 3D CT reconstructions. The classifications used so far should be revised as they do not reflect real types of these fractures...
