Proximal humerus fractures, although common, have high rates of failure after open reduction and internal fixation. The use of a fibular allograft has been explored as a means to decrease complications, particularly varus collapse and the need for revision surgery. The authors performed a retrospective review of 133 proximal humerus fractures managed surgically with locking plates (n=72) or locking plates with fibular allograft intramedullary struts (n=61). Demographic, intraoperative, and postoperative variables were collected and analyzed...

Multidirectionally unstable supracondylar humeral fractures cause severe instability in both flexion and extension movements. The traditional closed reduction often fails to overcome this lack of stability. The aim of this study is to use a closed reduction technique with a transolecranon pin to achieve temporary stability. From 35 pediatric multidirectionally unstable supracondylar humeral fractures hospitalized between March 2012 and March 2018 at our hospital, 23 fractures (65.7%) were treated with closed reduction and percutaneous pinning (CRPP) (group 1) and the remaining twelve fractures (34...

Vertical Pauwels Type III fractures of the neck of femur in young patients are difficult fractures to treat. These are usually as a result of high energy trauma which are associated with a significant degree of fracture comminution in the neck of femur. This makes the fracture reduction and fixation difficult. Many fixation methods and implants have been described for use in these fractures but are not without reported complications such as non-union and varus collapse. In this article, we highlight the incidence of fracture comminution in both the anterior and posterior cortices of the femoral neck, better visualised with axial computed tomography scanning and describe a simple technique utilizing lag screws and a DHS implant to adequately address these fractures...

OBJECTIVE: Patients undergoing long-segment fusions from the lower thoracic (LT) spine to the sacrum for adult spinal deformity (ASD) correction are at risk for proximal junctional kyphosis (PJK). One mechanism of PJK is fracture of the upper instrumented vertebra (UIV) or higher (UIV+1), which may be related to bone mineral density (BMD). Because Hounsfield units (HUs) on CT correlate with BMD, the authors evaluated whether HU values were correlated with PJK after long fusions for ASD...

BACKGROUND: Treatment of diaphyseal open tibia fractures often results in reoperation and impaired quality of life. Few studies, particularly in resource-limited settings, have described factors associated with outcomes after these fractures. QUESTIONS/PURPOSES: (1) Which patient demographic, perioperative, and treatment characteristics are associated with an increased risk of reoperation after treatment of open tibia fractures with intramedullary nailing or an external fixation device in Tanzania? (2) Which patient demographic, perioperative, and treatment characteristics are associated with worse 1-year quality of life after treatment of open tibia fractures with intramedullary nailing or an external fixation device in Tanzania? METHODS: A prospective study was completed in parallel to a similarly conducted RCT at a tertiary referral center in Tanzania that enrolled adult patients with diaphyseal open tibia fractures from December 2015 to March 2017...

BACKGROUND: Bone strength depends on multiple factors such as bone density, architecture and composition turnover. However, the role these factors play in osteoporotic fractures is not well understood. PURPOSE: The aim of this study was to analyze trabecular bone architecture, and its crystal and organic composition in humas, by comparing samples taken from patients who had a hip fracture (HF) and individuals with hip osteoarthritis (HOA). METHODS: The study included 31 HF patients and 42 cases of HOA who underwent joint replacement surgery between 1/1/2013-31/12/2013...

INTRODUCTION: Antegrade nailing of proximal femur or femoral shaft fractures is a proven treatment with good to excellent results. Nonetheless, clinical evidence from Asia indicates that proximal femur nails can be too proud at the greater trochanter (GT) causing irritation for some Asian patients. This study aimed to identify any significant differences in proximal nail misfit for a set of Asian and Caucasian femora. MATERIALS AND METHODS: Two nails (Gamma3, TFNA) were virtually inserted into 63 femoral 3D models (28 Japanese, 4 Thai, 31 Caucasian)...

BACKGROUND: Tibial plateau fractures (TPFs) are the most common among periarticular fractures. Mechanism of injuries is most from varus/valgus and flexion injury. Hyperextension type injuries are rare and easily to be overlooked. We reported 12 cases of this fracture type. Complications of early cases were reported, and treatment strategies of late cases were suggested. MATERIALS AND METHODS: From 2010 to 2016, we performed a retrospective analysis of 248 cases of TPFs in our institute and 12 cases of hyperextension bicondylar TPFs were diagnosed...

BACKGROUND: Osteoporosis is associated with the risk of fractures near the hip. Age and comorbidities increase the perioperative risk. Due to the ageing population, fracture of the proximal femur also proves to be a socio-economic problem. Preventive surgical measures have hardly been used so far. METHODS: 10 pairs of human femora from fresh cadavers were divided into control and low-volume femoroplasty groups and subjected to a Hayes fall-loading fracture test...

BACKGROUND: Bone cement distribution patterns in percutaneous kyphoplasty (PKP) is the key factor in keeping the vertebral stabilization and curative effect. However, the same cement volume can result in different bone cement distribution patterns and can thereby lead to different clinical outcomes. Therefore we investigated associations between cement distribution patterns and the occurrence rates of recompression in cemented vertebrae after PKP for patients with osteoporotic vertebral compression fractures (OVCFs)...

The aim of this study was to assess the effect of perch positioning on laying hens' locomotion and the resulting energy experienced at the keel. Twenty Nick Chick and 20 Brown Nick hens were trained to transition from a platform to a perch in several configurations. Three variables of perch positioning were tested in a 2 × 2 × 2 factorial design: direction (upward vs. downward), angle (flat vs. steep), and distance (50 cm vs. 100 cm). All hens were tested for five jumps of each treatment combination at 27-28 weeks of age...
