Avulsion fracture of the brachioradialis origin at its proximal attachment on the lateral supracondylar ridge of the distal humerus is exceedingly rare, and only two cases have been reported in the literature so far. In this article, we present a 38 years old patient who sustained a closed avulsion fracture of the lateral supracondylar ridge of left humerus at the proximal attachment of brachioradialis following a fall backwards on outstretched hand after being struck by a lorry from behind while riding on a two-wheeler (motorcycle)...

Fractures of the proximal humerus are highly related to age and osteoporotic bone remodeling. Previous studies have highlighted the cortex as a major side of the bone loss, but the microstructural changes of the humerus have not been evaluated entirely. Sixty-four (n = 64) humeri of a representative collective (18-100 years) were scanned with high-resolution peripheral quantitative computed tomography (82 µm). Bone mineral density (BMD), trabecular bone volume fraction (Tb.BV/TV), cortical thickness (Ct...

Proximal humerus fractures in the elderly are increasing in frequency as the population ages. The purpose of this study was to investigate surgical and cost trends in the Medicare population. The PearlDiver database was queried using diagnosis codes to identify Medicare recipients with proximal humerus fractures from 2005 to 2012. Surgical trends, demographics, and charge/reimbursement data were analyzed. There were 750,426 proximal humerus fractures in Medicare recipients during the 8-year period. Eighty-five percent of the fractures were treated nonoperatively; however, the percentage of operative vs nonoperative management increased significantly over time for all fractures, isolated fractures, and fracture dislocations...

BACKGROUND: With the introduction of the deltoid tuberosity index (DTI), a simple radiographic tool has become available to measure bone mineral density of the proximal humerus. The aim of this study was to assess the influence of local bone mineral density on the early failure rate after angular stable open reduction-internal fixation of proximal humeral fractures (PHFs). METHODS: We retrospectively followed up all patients treated with angular stable implants for PHFs from 2007 to 2014...

BACKGROUND: Proximal humeral fractures in elderly patients present with severe comminution and osteoporotic bone quality. Reverse shoulder arthroplasty has lately been proven beneficial in treating patients with complex proximal humeral fractures. The above technique is recommended and has better results in elderly than in younger individuals. METHODS: We performed a literature search in the databases Pubmed, Medline, EMBASE and Cochrane Library for published articles between 1970 and 2016 using the terms: proximal humerus fractures and reverse shoulder arthroplasty...

Alterations have been made over the years to the standard reverse total shoulder arthroplasty (RTSA) prosthetic components in an effort to decrease adverse events; this has led to the advent of a short humeral stem prosthesis. To the authors' knowledge, there are no reports describing the complication of a traumatic periprosthetic Wright and Cofield classification type A fracture with use of a short metaphyseal humeral stem component for RTSA. The authors describe a 49-year-old woman with this pathology who was treated with open reduction and internal fixation using a proximal humerus locking plate, unicortical and bicortical screw fixation, and a cerclage wire construct without the need to violate the shoulder joint or revise components...

Cortical desmoids are self-limiting fibro-osseous lesions commonly occurring at the medial supracondylar femur in active adolescents, at either the origin of the medial head of the gastrocnemius or at the insertion of the adductor magnus aponeurosis. Less commonly, in a similar demographic, cortical desmoids may occur in the proximal humerus medially at the insertion of the pectoralis major muscle or laterally at the insertion of the deltoid. The radiographic appearance of the proximal humerus cortical desmoid has been described previously, but not the MRI appearance...

BACKGROUND: An ideal animal model has always been the key to research the pathogenesis and treatment of adolescent idiopathic scoliosis (AIS), while available methods have obvious disadvantages. The deficiency of melatonin has been proved relating to AIS. In this research, we intended to apply Luzindole, the melatonin antagonist, in bipedal rat model, for the block of combination of melatonin and its receptor, to inhibit the melatonin effect, and then to understand whether this method can effectively improve the scoliosis rate of bipedal rat model, and investigate the role of melatonin in scoliosis...

BACKGROUND: Recently, minimally invasive plate osteosynthesis (MIPO) has been widely used for the treatment of proximal humeral fractures. However, there is concern about whether the MIPO in comminuted proximal humeral fractures is also comparable to open plating. The purpose of this study was to compare the clinical and radiographic outcomes of open plating and MIPO for acute displaced proximal humeral fractures. MATERIALS AND METHODS: In this prospective, randomized controlled study, 107 patients who had an acute proximal humeral fracture were randomized to either the open plating or MIPO techniques...

Peripheral quantitative computed tomography (QCT) has been used in poultry bone research in recent years to analyze cortical and cross-sectional geometry. For QCT to be used as a standard research tool for analysis of bones of laying hens (cortical thickness <2 mm), the accuracy of the scans must be assessed. The primary difference between the QCT and micro-computed tomography (micro-CT) is image resolution. Image resolution is inversely related to the pixel size. The aim of the current study was to correlate the cortical parameters measured using clinical CT scans with the measurements from micro-CT, the current gold standard...

Treatment of a nonunion of the proximal humerus remains a challenge because of the small proximal fragment and poor central cancellous bone stock of the humeral head. In this report, we describe our experience using a "half-folded" pedicled scapular bone flap with an anatomical locking plate to treat an atrophic nonunion of the proximal humerus in a 64-year-old right-handed woman. The patient had fallen and experienced a common humeral neck fracture 2.5 years previously. During the operation, we elevated the pedicled scapular bone flap, which measured 8...

Current studies of anuran morphology use sacral vertebrae, hindlimbs as main predictor for locomotor modes, while forelimbs and their segments were not analysed in this context. Due the fact that the complex interplay of numerous morphological traits determines the locomotion ability of anurans, we used ratios for both fore- and hindlimbs to obtain useful information of the structural and functional properties of locomotor system. We examined patterns of variation in total length of fore-, and hindlimbs as well as sacral vertebrae width and diapophyseal expansion in order to position two locomotor modes (jumpers and walkers) in a morphological shape space...

PURPOSE: A chevron osteotomy of the ulna is widely used to obtain intra-articular access to the elbow in the treatment of type C distal humerus fractures. The trochlear notch of the proximal ulna is divided into 2 articular parts by the "bare area." Ideally, the olecranon osteotomy should be centered on the bare area to minimize damage to the joint cartilage. The goals of this study were to describe the anatomy of the bare area and design an ideal chevron-shaped osteotomy. METHODS: We dissected 38 cadaver elbows and measured the width of the bare area, the distance between the tip of the triceps insertion and the area on the olecranon cortex corresponding to the bare area...

Although the proximal humerus is a common site of osteochondroma, osteochondroma arising from the lesser tuberosity of the proximal humerus is rare. Because of the anatomy of the shoulder, mechanical impingement can occur via direct contact of the protruding lesser tuberosity against the glenoid rim or coracoid. In younger patients, this may cause isolated tearing of the subscapularis. In this study, is presented a rare case of osteochondroma on the lesser tuberosity that caused a subscapularis tear after shoulder impingement in a 34-year-old male...
