Metaphysis cancellous bone fracture is one of the most common fracture types in clinical orthopedic practice. The specialized healing process of cancellous bone fracture has long been ignored by the academic society. Comparing with diaphyseal cortical bone healing, cancellous bone healing showed less bone tissue necrosis, barely any hematoma formation, limited inflammation events and no externa...

PURPOSE To present a previously unreported avulsion-type injury of the rectus muscle, usually the inferior rectus, and detail its diagnosis and operative repair. METHODS Thirty-five patients underwent repair of flap tears of 42 rectus muscles. The muscle abnormality was often subtle, with narrowing or thinning of the remaining attached global layer of muscle. The detached flap of external (or...

To asses fracture risk, bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA) is the most commonly used tool. The search for clinical risk factors is also advised and can provide a 10-year fracture probability (FRAX model). Another important determinant of bone strength is bone remodeling. High bone remodeling rates have been associated with a higher fracture risk and bo...

conclusions time plays an important role in treatment results of femoral neck fractures. to treat the fractures, closed reduction and fixation using cannulated screws may still be the best option. objectives the present study aimed to evaluate long-term results of delayed fixation of femoral neck fractures using cannulated screws. patients and methods this retrospective descriptive-analytical s...

subchondral insufficiency fracture of the femoral head (siffh) is characterized by acute onset hip pain without overt trauma. it appears as a low intensity band with bone marrow edema on t1-weighted mri. the most common course of treatment is protected weight bearing for a period of several weeks. total hip arthroplasty (tha) has been commonly used if the patient does not respond to the initial...

in this paper, an efficient algorithm is proposed for detection of vertical root fractures (vrfs) in periapical (pa), and cone-beam computed tomography (cbct) radiographs of nonendodontically treated premolar teeth. pa and cbct images are divided into some sub-categories based on the fracture space between the two fragments as small, medium, and large for pas and large for cbcts. these graphics...

OBJECTIVES To calculate the volume of bone in 3 areas of the deep lateral orbit that are available for removal in decompression surgery and to demonstrate these 3 areas within a 3-dimensional computed tomographic reconstruction of the orbit. DESIGN The 3 areas of bone in the deep lateral orbit were designated the lacrimal keyhole, the sphenoid door jamb, and the basin of the inferior orbital ...

With the recent advent of accurate orbital volume assessment by computed tomography, a retrospective analysis was made of 31 patients with 'pure' blowout fracture of the orbital floor, managed either surgically or conservatively, to determine whether orbital volume measurement could provide an additional parameter of use in the management of such fractures. There was a significant difference in...

BACKGROUND Trapdoor-type orbital fractures usually associated with marked motility restriction are common in the pediatric age group. We reviewed the characterization and surgical outcomes of orbital blow-out fracture in children. METHOD This is a retrospective review study. From Jan. 1997 to Dec. 2006, 75 patients under 18 years of age with orbital blow-out fractures were seen in the departm...
