BACKGROUND: Compared with total shoulder arthroplasty (TSA), total shoulder surface replacement (TSSR) may offer the advantage of preservation of bone stock and shorter surgical time, possibly at the expense of glenoid component positioning and increasing lateral glenohumeral offset. We hypothesized that in patients treated for osteoarthritis with a sufficient rotator cuff, TSA and TSSR patients have comparable functional outcome, glenoid component version, and lateral glenohumeral offset...

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...

INTRODUCTION: The shoulder arthroplasty brings satisfaction to patients in terms of quality of life and indolence. However whether anatomic implant or reverse, it does not escape from the loosening of the glenoid component. Moreover, optimal implantation is required to ensure the functional outcome without shortening of the arm. The purpose of this study is obtain CT scan evaluation of the glenoid bone stock in order to optimize glenoid component implantation and obtain a reference to determine optimal humeral component placement in case of humeral proximal fracture...

BACKGROUND: This study's purpose was to assess patient-based functional outcomes following open reduction and internal fixation (ORIF) of displaced scapular body and glenoid neck fractures. This series represents a 9-year experience at a level-I trauma center and referral destination for this injury. METHODS: A database was established to record surgical and functional outcomes of scapular fractures treated with ORIF. For this report, the cases of all patients who had a glenoid neck or scapular body fracture (AO/OTA 14-A3 or 14-C1) without intra-articular involvement were reviewed...

The scapula is valuable for sex estimation in human skeletons. Muscles provide protection to the scapula making it difficult to fracture, therefore increasing the potential for undamaged scapulae at forensic scenes. The goal of this project is to evaluate the accuracy of discriminant functions, created using an indigenous Guatemalan and contemporary Mexican population, when applied to a contemporary Chilean sample for estimation of sex from the scapula. The length of the glenoid cavity (LGC) and breadth of the glenoid cavity (BGC) were measured...

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: A porous tantalum glenoid component for total shoulder replacements was introduced in 2003 to promote biologic ingrowth. However, reports of component failure prompted design modifications. The purpose of this study is to present the largest series to date, of TSR with the second-generation Trabecular Metal™ glenoid component. METHOD: A radiologic and clinical evaluation of the second-generation TM glenoid was conducted in consecutive cases of 76 shoulders (66 patients) with a mean follow-up of 43...

Traumatic dislocation of the mandibular condyle into the middle cranial fossa is an extremely rare complication of maxillofacial injury. The rarity of this injury has led researchers to propose a set of anatomic features that might explain this injury. These features include a small rounded condylar head, hyper-pneumatization of the temporal bone, a thin roof over the glenoid fossa, and missing posterior teeth. The greatest risk factor for this injury is a blow to the chin when the mouth is open without fracture of the condyle (and therefore no dissipation of the forces)...

BACKGROUND: Glenoid erosion is one of the main concerns in shoulder hemiarthroplasty. The goal of this study was to quantify glenoid erosion and to identify risk factors in patients with humeral hemiarthroplasty. METHODS: There were 118 shoulders in 113 patients available for a standardized retrospective review. Erosion was graded as follows: grade 1, none; grade 2, mild (erosion into subchondral bone); grade 3, moderate (medialization of subchondral bone with hemispheric deformation); or grade 4, severe...

BACKGROUND: Total shoulder arthroplasty for end-stage glenohumeral arthritis with severe glenoid bone loss poses a unique challenge for shoulder surgeons. Current surgical solutions are limited and associated with high complication rates. We hypothesized that a custom-made computer-aided design-computer-aided manufacturing (CAD-CAM) total shoulder replacement (TSR; Stanmore Implants Worldwide, Elstree, UK) resembling a total hip prosthesis could offer a reliable alternative for this challenging subset of patients...

BACKGROUND: Revision of failed shoulder arthroplasty is often associated with poor results and a high rate of complications. Significant humeral bone loss after removal of long stems poses a considerable surgical challenge. Therefore, the aim of our study was the evaluation of the clinical and radiologic outcome of cemented long-stem humeral components in revision reverse shoulder arthroplasty with a minimum 5 years' follow-up. METHODS: Between June 2001 and June 2009, revision reverse shoulder arthroplasty using long-stem cemented humeral components was performed in 124 patients...

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: The safety of arthroplasty in patients with a previous periprosthetic joint infection (PJI) remains unclear. The objective of this study was to determine whether patients with a history of a properly treated PJI complicating lower extremity arthroplasty can safely undergo shoulder arthroplasty without an increased risk of shoulder infection or compromise in their clinical outcomes. METHODS: Between 2002 and 2013, 36 patients with successful treatment of an infected lower extremity arthroplasty underwent a subsequent primary shoulder arthroplasty...

BACKGROUND: The purpose of this study was to evaluate the outcome of hemiarthroplasty for comminuted proximal humerus fractures and to verify the risk factors for functional and radiologic outcomes. MATERIALS AND METHODS: We treated 29 comminuted proximal humerus fractures by hemiarthroplasty with a low-profile prosthesis and a bone block graft, with an average follow-up period of 53.9 (24-119) months. The patients' mean age at surgery was 71.7 (52-85) years. We evaluated visual analog scale (VAS) scores for pain and satisfaction, active range of motion, modified University of California-Los Angeles (UCLA) score, and shortened Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score...

Head-splitting fractures occur as a result of violent compression of the head against the glenoid; the head splits and the tuberosities may remain attached to the fragments or split and separate. Isolated humeral head-splitting fractures are rare injuries. Favorable results with osteosynthesis can be difficult to achieve because of the very proximal location of the head fracture and associated poor vascularity. We present a case of a 67-year-old man who sustained a severe, sword-like trauma to his left shoulder after a road traffic accident with associated isolated open Gustilo-Anderson IIIA humeral head-splitting fracture...

Surgical fixation of displaced, intra-articular glenoid fractures represents a clinical challenge. These fractures have traditionally been treated through open approaches to the glenohumeral joint; however, the morbidity associated with open surgery may be reduced with arthroscopic techniques. Previously described arthroscopic methods commonly use clamps and/or Kirschner wires to obtain and maintain provisional fixation. We describe our technique for minimally invasive, arthroscopic fixation of glenoid rim fractures using labral repair as an indirect reduction maneuver, followed by final fixation with an extra-articular screw...

BACKGROUND: Locked anterior shoulder (LAS) with static instability and anterior glenoid bone loss is challenging in the elderly population. Reverse shoulder arthroplasty (RSA) has been employed in treating these patients. No study has compared RSA for LAS with classically indicated RSA. METHODS: A retrospective case-control study of patients treated with RSA for LAS with glenoid bone loss and static instability was performed using matched controls treated with primary RSA for classic indications...

Acute shoulder injuries in adults are often initially managed by family physicians. Common acute shoulder injuries include acromioclavicular joint injuries, clavicle fractures, glenohumeral dislocations, proximal humerus fractures, and rotator cuff tears. Acromioclavicular joint injuries and clavicle fractures mostly occur in young adults as the result of a sports injury or direct trauma. Most nondisplaced or minimally displaced injuries can be treated conservatively. Treatment includes pain management, short-term use of a sling for comfort, and physical therapy as needed...
