BACKGROUND Penile fracture is a relatively rare traumatic rupture of the tunica albuginea of one or both corpora cavernosa of an erect penis. It is a real urological emergency which needs early assessment and surgical management. METHODS Twelve (12) cases of penile fracture were reviewed from July, 1997 to July, 2007 in the Department of Urology, Ayub Teaching Hospital Abbottabad. All cases p...

L5S1 fracture-dislocations are rare three-column injuries. The infrequency of this injury has led to a lack of a universally accepted treatment strategy. Transforaminal lumbar interbody fusion (TLIF) has been shown to be an effective approach for interbody fusion in degenerative indications, but has not been previously reported in the operative management of traumatic lumbosacral dislocation. T...

Sacral stress fractures are common in elderly people. However, sacral stress fracture should be always screened in the differential diagnoses of low back pain during the postpartum period. We present a case of sacral fracture in a thirty-six-year-old woman with low back pain and severe right buttock pain two days after cesarean section delivery of a 3.9 Kg baby. The diagnosis was confirmed by M...

Damage and fracture mechanisms of two 2198 Al-Li thin sheet alloys having different thicknesses (2 and 6 mm) are investigated. Two heat treatments are studied: T3 and T8. Mechanical tests are carried out on flat specimens including smooth tensile samples and U-notched specimens (with various notch radii). Test data are used to identify the parameters of constitutive equations describing plastic...

The aim of this study was to clarify the effects of micro surface defects introduced by the focused ion beam (FIB) technique on the fracture strength of ceramics. Three-point bending tests on alumina-silicon carbide (Al₂O₃/SiC) ceramic composites containing crack-like surface defects introduced by FIB were carried out. A surface defect with area in the range 19 to 35 µm was introduced at the ce...

The ARIES project is currently proposing an all-tungsten divertor for their tokamak designs. In designing such a component, fracture will be a critical failure mechanism, due to the limited ductility of the tungsten. Hence, this paper presents a series of fracture mechanics-based analyses to demonstrate the feasibility of using an alltungsten divertor in a commercial device. The analyses presen...

Postoperative blood recovery in eighty elderly patients (11 male, 69 female) treated for femoral neck fracture was prospectively studied. Twenty-eight patients underwent hemiarthroplasty for intracapusular fracture and 52 underwent Dynamic Hip Screw fixation for extracapsular femoral neck fracture. The mean blood drainage in the postoperative period and the mean drop in haemoglobin level was hi...

OBJECTIVE The goal of the study was to compare functional results in different treament options in cutting-out, and analize factors associated to failure. MATERIAL AND METHODS Retrospective cohort study in 56 patients diagnosed with cutting-out between 2000-2010. Groups were based on rescue treatment: arthroplasty versus alternative treatment. Demographics, fracture characteristics, osteosynt...
