We measured the distribution of contact area and pressure between the acetabulum and the femoral head of cadaveric pelves in three different conditions: intact, with an operatively created fracture of the posterior wall, and after anatomical reduction and fixation of the fracture with a buttress plate and interfragmentary screws. The study involved eight cadaveric hip joints from five pelves lo...

Delayed posterior wall (PW) peak in the detection of PW asynergy was studied by M-mode echocardiography in 53 patients with angiographically proven PW aneurysm, hypokinesis and normal PW. The timing of the PW peak was evaluated by the intervals between (1) the aortic valve closure (Ac) and the PW peak, and (2) the R wave of the electrocardiogram and the PW peak (R-peak). The PW excursion predic...

BACKGROUND The results after acetabular fracture are primarily related to the quality of the articular reduction. We evaluated the results of internal fixation of posterior wall fractures with using three-step reconstruction. METHODS Thirty-three patients (mean age at the time of injury, 47.9 years; 28 males and 5 females) were followed for a minimum of 2 years after surgery. The three-step r...

BACKGROUND Variations in position of the vermiform appendix considerably changes clinical findings. Retrocaecal appendicitis presents with slightly different clinical features from those of classical appendicitis associated with a normally sited appendix. K-sign looks for the presence of tenderness on posterior abdominal wall in the retrocaecal and paracolic appendicitis. This is the first case...

Posterior wall velocities have been advanced as a useful technic for the assessment of left ventricular function. To evaluate the echocardiographic effects of regional myocardial infarction on posterior wall motion (PWM), measurements were obtained in 22 open-chest dogs. Coronary artery ligation produced infarction of the apex in 11 dogs (group I) and the posterior wall in 11 dogs (group II). E...

Diverticula of the left atrium are very rare malformations of unknown etiology and may be associated with arrhythmias, thromboembolism, or mitral valve regurgitation. We report a patient with suspected coronary artery disease (CAD) in whom we performed a low-dose computed tomography coronary angiography using prospective electrocardiogram triggering. CAD could be ruled out. Incidentally, we fou...

abstract traumatic hip dislocations are common in high-energy motor vehicle accidents. we present a case of a 43-year old man who sustained posterior hip dislocation with posterior wall acetabular fracture and ipsilateral intertrochantric fracture following a motorcycle accident. urgent open reduction and internal fixation of the hip fracture-dislocation and fixation of intertrochantric fractur...

Vaginal wall cysts occur rarely and can cause a variety of symptoms. A 35 year old woman presented with history of mass bulging from vagina for a year. Pelvic examination revealed a reducible non-tender mass protruding from the vagina and diagnosed as rectocele. Physical examination is important for the detection and characterization of vaginal cysts but may be inadequate for appropriate diagno...
