: Incidence of fragility fracture of a population-based cohort of 345 patients with sarcoidosis was compared with age and sex-matched comparators. The incidence of fragility fracture was higher among patients with sarcoidosis with hazard ratio (HR) of 2.18. INTRODUCTION: Several chronic inflammatory disorders increase the risk of fragility fracture. However, little is known about the risk of fragility fracture in patients with sarcoidosis. METHODS: This study was conducted using a previously identified population-based cohort of 345 patients with incident sarcoidosis from Olmsted County, Minnesota...

Growth plate injuries (Salter-Harris type 1 or physeal fractures) of the long bones in the newborn are easily misdiagnosed as joint fractures with dislocations due to their nonossified epiphyses on plain radiographs. Diagnosis with musculoskeletal ultrasound (US) is advantageous due to its ability to visualize the nonossified epiphysis. We present two cases of humeral growth plate fractures in newborns, one at the shoulder (proximal humerus) and the other at the elbow (distal humerus). These cases emphasize the importance of quick and noninvasive diagnosis with US to avoid unnecessary intervention...

Axillary nerve injury is a risk of the deltopectoral approach to the proximal humerus. The anterior motor branch is potentially vulnerable during subdeltoid dissection. Insertion of the pectoralis major tendon is an easily identifiable landmark on the humerus. This anatomical study explored whether the superior aspect of the pectoralis major tendon is a useful landmark for localizing the anterior motor branch of the axillary nerve as it travels under the lateral and anterior deltoid muscle. A total of 30 fresh-frozen human bilateral cadaveric upper extremities were examined...

BACKGROUND: Many anthropometric studies of the normal glenohumeral relationship have been performed for the implant design and to identify reference points for the correct placement of the prosthesis in glenohumeral joint replacement. However, whether those implantation marks, which adopted from European or American, can achieve the same precision to Eastern Asian, specifically Chinese is still unknown. MATERIALS AND METHODS: One hundred eighty healthy were scanned using CT...

PURPOSE: To evaluate the number of connective tissue progenitor cells (CTPs) and nucleated cells obtained during bone marrow aspiration (BMA) from the proximal humerus using either a fenestrated or a nonfenestrated trocar and determine differences in varying amounts of aspiration volume. The first hypothesis was that the number of CTPs extracted with the fenestrated trocar would be greater due to its potential to extract more cells through its fenestrations. The second hypothesis was that using consecutive aspirations with either trocar would provide a consistent number of CTPs and nucleated cells throughout the aspiration with no significant decrease of cells at the end...

Background and purpose - Fracture healing involves different inflammatory cells, some of which are not part of the traditional bone field, such as B-cells and cytotoxic T-cells. We wanted to characterize bone healing by flow cytometry using 15 different inflammatory cell markers in a mouse model of metaphyseal injury, and incidentally discovered a previously unknown general skeletal reaction to trauma. Material and methods - A bent needle was inserted and twisted to traumatize the cancellous bone in the proximal tibia of C57/Bl6 female mice...

Cryptococcosis is an invasive fungal infection that is common in immunocompromised patients. A 22-year-old woman with Ewing sarcoma in the right proximal humerus was treated by resection and chemotherapy. Computed tomography detected a small nodule in her right upper pulmonary lobe after completion of her chemotherapy. With the presumptive diagnosis of pulmonary metastasis, she underwent resection. Evaluation of the resected specimen revealed pulmonary cryptococcosis, and the patient was treated with oral fluconazole for 18 weeks...

The treatment of the four-part fractures of the proximal humerus remains a therapeutic challenge. The decision-making is based on preoperative criteria concerning the displacement of the fracture, the stability of the fracture and the risk of avascular necrosis of the humeral head. The aim of this study was to analyse the inter- and intra-observer reproducibility of those criteria previously described by Hertel. Three observers analysed three times 20 radiologic files comprising 2D X-rays, 2D CT scan and 3D reconstructions for the intra-observer study, and an expert committee was used to assess the inter-observer reproducibility...

INTRODUCTION: Fracture impaction is a surgical technique used to support the fractured humerus with locking plate or intramedullary nail when treating proximal humeral fractures. However, few studies have investigated the mechanical difference between fracture impaction with locking plate and with intramedullary nail. The mechanism of fracture impaction to increase stability is still unclear. The aim of this study was to use numerical methods to compare the biomechanical effect of treating proximal humeral fracture...

Quadrilateral space syndrome (QSS) is the term used to describe axillary nerve palsy due to compression of the axillary nerve and posterior circumflex artery in the quadrilateral space. The precise pathophysiology of QSS is still unclear; hence, a consensus of diagnosis and treatment for QSS has not yet been achieved. The authors present the case of a 17-year-old male baseball player with symptoms of QSS, including right elbow and shoulder joint pain and upper limb numbness while throwing. The symptoms had worsened during baseball...

BACKGROUND: Straight antegrade intramedullary nailing of proximal humerus fractures has shown promising clinical results. However, up to 36% of all humeri seem to be "critical types" in terms of the potential violation of the supraspinatus (SSP) tendon footprint by the nail's insertion zone. The aims of this study were to evaluate if a computed tomography (CT) scan could reliably predict the nail's entry point on the humeral head and if it would be possible to preoperatively estimate the individual risk of iatrogenic violation of the SSP tendon footprint by evaluating the uninjured contralateral humerus...

INTRODUCTION: Minimally invasive lateral placement of plates on the humerus may be associated with a risk of injury to the radial nerve. Whereas this potential complication has been investigated in several studies, there is no data regarding potential injuries to the distal insertion of the deltoid muscle when the plates are passed distally in a submuscular tunnel. METHODS: Minimally invasive plate placement was performed on eight arms in fresh cadavers. A lateral deltoid split approach was made and the plates were introduced in an antegrade submuscular manner from proximal to distal...

BACKGROUND: The main reconstruction techniques for proximal humerus tumors include osteoarticular allografts (OAs), endoprostheses (EPs), or allograft prosthetic composites (APCs). A common complication is infection, and constructs involving the use of allografts are believed to be at a higher risk of infection. Literature comparing infection rates between different modalities of reconstruction is scarce and underpowered. The study purposes were (1) to determine and compare the prevalence of infection in patients who underwent reconstruction of the proximal humerus including OAs, EPs, and APCs; (2) to identify preoperative, perioperative, and postoperative predictors of infection that might be modifiable; and (3) to present our protocol of treatment in patients with superficial and deep infections...

BACKGROUND: Low socioeconomic status and Medicaid insurance as a primary payer have been associated with major disparities in resource utilization and risk-adjusted outcomes for patients undergoing total joint arthroplasty. With the expansion of Medicaid through the Affordable Care Act in 2014, examination of these disparities has become increasingly relevant for the treatment of proximal humerus fracture (PHF). METHODS: The Healthcare Cost and Utilization Project Nationwide Inpatient Sample database was used to identify patients who were treated for PHF from 2002 to 2012...
