High-resolution 3-dimensional cartilage-specific magnetic resonance imaging (MRI) was performed at 3 T to test the following hypotheses: (1) there is a nonuniform cartilage thickness distribution both on the proximal humerus and on the glenoid surface and (2) the glenohumeral joint as a combined system is congruent with the level of the joint cartilage surface without substantial radial mismatch. Inclusion of 38 volunteers (19 females, mean age 24.34 ± 2.22 years; range 21-29 years) in a prospective study...

OBJECTIVES: Proximal humerus fractures are a common injury in the elderly population that can usually be managed non-operatively. However, arthroplasty has become increasingly utilized for complex fractures and poor bone quality. We evaluated national trends in treatment, specifically looking at the adoption of reverse total shoulder arthroplasty. METHODS: The incidence of proximal humerus fractures was calculated from the Nationwide Emergency Department Database (NEDD) from 2006-2012...

Although most pediatric proximal humeral fractures can be successfully treated conservatively with satisfactory results, many operative techniques have been described for the treatment of displaced proximal humeral fractures. The aim of this study is to evaluate the efficacy of percutaneous fixation using a modified palm tree technique for proximal humerus fractures in children. Between March 2011 and May 2013, the modified palm tree technique was used for the management of 30 children (20 boys and 10 girls) with displaced proximal humeral fractures...

In patients aged over 70 years, a non-functioning rotator cuff is an indication for a reversed shoulder prosthesis. Here we describe an 84-year-old woman with rotator cuff arthropathy and a 76-year-old man with a proximal humerus fracture, who both received a reversed shoulder prosthesis. This prosthesis decreases pain and improves the range of movement; however, the high risk of complications associated with this prosthesis should be taken into account and should be discussed preoperatively.

BACKGROUND: The B-B Score is a straightforward kinematic shoulder function score including only two movements (hand to the Back + lift hand as to change a Bulb) that demonstrated sound measurement properties for patients for various shoulder pathologies. However, the B-B Score results using a smartphone or a reference system have not yet been compared. Provided that the measurement properties are comparable, the use of a smartphone would offer substantial practical advantages. This study investigated the concurrent validity of a smartphone and a reference inertial system for the measurement of the kinematic shoulder function B-B Score...

The implants used in reverse shoulder arthroplasty were originally designed for white patients; thus, they might not be optimal for smaller Asian patients. The selection of reverse shoulder arthroplasty systems is limited in Japan. The purpose of this study was to measure the geometry of the proximal humerus in elderly Japanese patients to inform implant selection according to humerus size. This study included 155 shoulders from 148 patients 50 years or older who underwent computed tomography for shoulder disorders other than arthritis and trauma...

BACKGROUND: Proximal humerus fractures are common injuries. Locking plates and anterograde medullary nails are the two most common fixation devices used when open reduction and internal fixation (ORIF) is indicated. Complications related to fracture and to hardware are numerous, especially shoulder stiffness. The goal of this study is to report the clinical outcomes of gleno-humeral arthroscopic arthrolysis combined with hardware removal. METHODS: A total of 58 patients (25 men, 33 women) with a mean age of 58 years (24-79) were reviewed retrospectively...

Fracture sequelae of the proximal humerus poses a complex management decision due to the frequent deformity and its consequences on the peri-articular soft tissues. These patients are frequently elderly with significant medical comorbidities. Due to the age of the patient there is frequently rotator cuff deficiency and therefore the reverse shoulder arthroplasty (RSA) becomes the arthroplasty of choice. We have performed a systematic review of the literature and report nine studies presenting RSA for the treatment of fracture sequelae of the proximal humerus...

Osteoblastoma is benign bone forming tumour with rare malignant transformation. The common locations include spine, proximal humerus and hip. It rarely affects the talus. A case of osteoblastoma of the talus in a 33-years old healthy male who presented to the foot and ankle clinic in October 2015 complaining of pain of the right ankle for 12 months following football injury is discussed.

REVIEW
Jennifer S Walsh, Tatiane Vilaca
In an increasingly obese and ageing population, type 2 diabetes (T2DM) and osteoporotic fracture are major public health concerns. Understanding how obesity and type 2 diabetes modulate fracture risk is important to identify and treat people at risk of fracture. Additionally, the study of the mechanisms of action of obesity and T2DM on bone has already offered insights that may be applicable to osteoporosis in the general population. Most available evidence indicates lower risk of proximal femur and vertebral fracture in obese adults...

Chondroblastoma is a benign bone tumor, represents 1%-2% of all primary bone tumors, typically seen in patients 10-25-year-old and more common in males. It occurs most frequently in the distal femur, proximal tibia, and proximal humerus. Soft tissue extension is extremely rare. Adjacent joints may develop effusions, but the tumor mass protruding into the joint has never been seen in case of chondroblastoma. We report a rare case of intra-articular chondroblastoma arising from proximal tibia in a 16-year-old boy and growing into the knee joint mimicking an intra-articular osteochondroma...

Proximal humerus fractures are common, but associated injury of the axillary artery is uncommon. The majority of published blunt traumatic axillary artery injuries are associated with anterior glenohumeral dislocation; a few are associated with isolated proximal humerus fractures or fracture-dislocation. Experience within our institution demonstrates that axillary artery injury is often unrecognized on initial presentation owing to palpable peripheral pulses and the absence of ischemia and places the hand at risk of necrosis and amputation if there is prolonged ischemia and the forearm at risk of compartment syndrome after revascularization...

Proximal humerus fractures are characterized by their frequency, the difficulties and the absence of treatment of reference. New means of osteosynthesis appeared since the years 2000, as well as the preferential recourse to the reversed prostheses of shoulder. A chapter is dedicated to classifications, as a whole not very reproducible. The new treatments are represented by the nails, such as Telegraph(®), and the plates with blocked screws. It appeared a real progress in the osteosyntheses and became infinitely more solid with the stability of the screws in the bone...

Extraskeletal myxoid chondrosarcoma is a rare neoplasm of soft tissue. The usual location is in deep parts of the proximal extremities and limb girdles in middle-aged adults. The bone location as primary location is extremely rare and few cases are reported. We present three cases arising in bone with molecular confirmation using both RT-PCR and FISH analysis. Patients include two men and one woman with an age of 62, 69 and 73 years old. The mean size of the lesion was 13cm (range 8-18cm). Tumors arose in the iliac bone in two cases and in the proximal humerus in the other case...

BACKGROUND: Deformity and growth arrest of the humerus in children may result as sequelae of proximal humerus fractures and unicameral bone cysts, or as complications of their treatment. As approximately 80% of the growth of the humerus arises from the proximal physis, the resultant upper limb-length discrepancy can be substantial. Benefits to lengthening the shortened arm have been previously demonstrated with the use of external fixation devices. To our knowledge, no reports have been published on the use of intramedullary implants for this purpose...

INTRODUCTION: Cemented stem remains the gold standard for prosthesis in trauma. The purpose of this study was to evaluate the functional and radiological outcomes of a cementless, trauma-specific locked stem (hemi and reverse) for 3- and 4-part proximal humeral fractures. MATERIALS AND METHODS: One hundred and thirty-four 3- and 4-part fractures have been treated by locked stem, 69 with hemiarthroplasty [mean age 68 years (50-90)] and 65 with reversed [mean age 78 years (66-91)]...

BACKGROUND: The humerus shaft is one of the sites with the largest probability of developing pseudoarthrosis after fracture. We present the results of nine patients with atrophic pseudoarthrosis of humeral shaft treated with angular stability plate associated with allograft and platelet-rich plasma (PRP), after a first treatment with intramedullary nail to correct the fracture. MATERIAL AND METHODS: From January 2012 to December 2014, nine patients were treated for atrophic pseudoarthrosis (PSA) of humeral shaft treated previously using intramedullary nail; seven humeral diaphysis fractures were located in the middle-proximal third and two in the middle third...

We report a rare case of disseminated coccidioidomycosis with multifocal musculoskeletal involvement. The patient presented to the emergency department with left shoulder pain and swelling. Magnetic resonance imaging of the left shoulder revealed enhancing soft tissue masses, bony lesions, and fluid collections in and around the glenohumeral joint with involvement of the proximal humerus, glenoid, and rotator cuff musculature. Multiple additional areas of involvement were subsequently discovered. Fungal cultures confirmed coccidioidomycosis infection at all surgical sites with superimposed polymicrobial bacterial infection in the left shoulder...
