BACKGROUND A known species Lutztrema (Lutziella) microacetabularae Rhode, 1966 is being described for the first time from Pakistan. This species is characterized by having body long and slender, oral sucker subterminal, acetabulum smaller than oral sucker lying in anterior third of the body, pharynx small, esophagus prominent which become gradually wider and bifurcates in to two rudimentary cae...

Normal development of the acetabulum is crucial to the growth and stability of the hip. Twenty-five New Zealand white rabbits (postweaning) weighing 1.5 to 2.2 kg were used. Both hips were exposed through an anterolateral approach. On the right hip, a fixed area of superolateral physeal cartilage was damaged with drills. Sham open reduction was performed for the left hip. Radiographic changes o...

Lasiotocus lizae sp. n. (Digenea: Monorchiidae) was collected from the intestine of Liza carinata (Valenciennes) (Mugilidae, Perciformes) in the Taiwan Straits, China. L. lizae is most similar to Lasiotocus glebulentus Overstreet, 1971 from the intestine of Mugil cephalus from the Northern Gulf of Mexico in having tightly compacted vitellaria, a genital pore sinistral to the midline, the ovary ...

We performed Charnley total hip arthroplasties on 64 patients (71 hips) between 1976 and 1984 for moderate congenital acetabular dysplasia in which a superolateral cement thickness of less than 20 mm was expected when the cup was placed in the true acetabulum at an angle of 45 degrees. Of these, 59 hips were examined 10 to 17 years after operation; 37 (group A) had been operated on between 1976...

A retrospective analysis was performed of eight patients with an open triradiate cartilage, who underwent resection for osteosarcoma and reconstruction of the proximal femur with a hemiarthroplasty, in order to identify changes of acetabular development. An analysis of the centre-edge angle, teardrop-to-medial prosthesis distance, superior joint space, teardrop-to-superior prosthesis distance, ...

Certain deformities of the hip joint seem to predispose the hip to the development of osteoarthrosis. Successful surgical correction of these deformities before the onset of osteoarthrosis requires accurate characterization of the anatomic deviations from normal as the first step in planning corrective osteotomy. Three-dimensional computed tomography (CT) reconstruction in planning reconstructi...

The volatile halogenated methyl ethyl ether, isoflurane, used as an anaesthetic, inhibits actin-based dynamics directly or indirectly in animal cells. In plant cells, most intracellular movements are related to actin pathways. We have used isoflurane in a unicellular alga, Acetabularia acetabulum, to test the dynamics of choloroplast organization. By measuring the delayed luminescence, we found...

BACKGROUND Acetabular cementation during total hip arthroplasty is considered difficult mainly due to the appearance and anatomy of the acetabulum. Improved cementation technique has been shown to improve the longevity of acetabular components. METHOD We designed a ceramic model to investigate the effect of varying the initial cement pressurization and cup introduction times on the depth of c...

Unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC) are benign cystic lesions of bone which are easily diagnosed. However, unusual locations may lead to a false diagnosis. Therefore the aim of this retrospective study was to determine the frequency of unusual localizations. The authors studied 451 cases with histopathologically confirmed diagnosis of UBC or ABC, seen between 1981 and 20...

A 34-year-old man had a traumatic thoracic spinal cord injury, with vertebral fracture and a right acetabulum fracture. Dorsal spinal fusion of T6 through T9 was performed on admission. The initial American Spinal Injury Association (ASIA) Impairment Scale (C) showed incomplete motor T10 lesion. Exoskeletal locomotion training with hybrid assistive limb started 77 days post trauma after radiolo...
