The patella plays an important role in the knee joint extension, and a patella fracture requires surgical treatment when it is accompanied by displacement of bone fragments and a joint surface gap. In patella fractures, there is disruption of the soft tissue structures that support the knee extension mechanism. We use a method of percutaneous cerclage wiring to fix the patella and include the p...

The number of deep brain stimulation (DBS) hardware complications has increased during the past decade. In cases of abnormally high lead impedance with no evidence of a macroscopic fracture, optimal treatment options have not yet been established. Here, we present the case of a 49-year-old woman with a 12-year history of Parkinson's disease who received bilateral subthalamic nucleus DBS in Marc...

This is a detailed report of a case and a review of literature concerning the patellar sleeve fracture. The diagnosis of this type of fracture is often missed in the emergency room, which the mentioned case also stresses. The fracture is a subtype of patellar fractures, and is mostly seen among children between eight between sixteen years of age. The trauma mechanism is an indirect powerful ext...

The incidence rate of chronic lymphocytic leukemia (CLL) in the United States is approximately 0.005%; men are at slightly higher risk than women. Bony involvement or pathological fracture rarely occurs in CLL, and it may be the initial presentation. An 85-year-old woman presented with acute respiratory failure secondary to pneumonia. Symptomatology included dyspnea. She was found to have patho...

fractures with an intact posteromedial buttress, have been successfully treated with a sliding hip screw or blade.1 However, unstable intertrochanteric fractures tend to collapse even after adequate reduction and fixation with plating, and thus intramedullary nailing is recommended.2 Unstable intertrochanteric fractures include fractures with posteromedial comminution, a reverse oblique configu...

BACKGROUND Supracondylar fracture of humerus is the most common fracture in first decade of life. There are various treatment modalities for this fracture i.e closed reduction and casting, open reduction and internal fixation and percutaneous pinning. Study was conducted to know the outcome of Percutaneous Pinning in the management of displaced supracondylar fracture of humerus in children. M...

This is the second in a series of two papers generated from a study on probabilistic meshless analysis of cracks. In this paper, a stochastic meshless method is presented for probabilistic fracture-mechanics analysis of linear-elastic cracked structures. The method involves an element-free Galerkin method for calculating fracture response characteristics; statistical models of uncertainties in ...

OBJECTIVE To compare the fixation stability in the femoral head with sliding hip screw versus helical blade designs for unstable, intertrochanteric hip fractures. METHODS A simulated, unstable intertrochanteric hip fracture was created in six pairs of cadaveric femurs. One of each pair was treated using an intramedullary nail with a sliding hip screw (ITST) for femoral head fixation and the o...

Bone fracture is a health concern for those with aged bone and brittle bone diseases. Mouse bone is widely used as a model of human bone, especially to investigate preclinical treatment strategies. However, little is known about the mechanisms of mouse bone fracture and its similarities and differences from fracture in human bone. In this work we present a methodology to investigate the fractur...

Carpal malalignments in malunion of distal radius fracture are considered as an adaptive response of the carpus to loss of normal architecture of the distal radius. This condition leads to mechanical overload, ligament attenuation and progressive dynamic instability around the wrist joint. Radial corrective osteotomy is suggested as a treatment option of carpal malalignment after distal radius ...
