Felidae species show a great diversity in their diet, foraging and hunting strategies, from small to large prey. Whether they belong solitary or group hunters, the behavior of cats subdue resisting prey presents crucial differences. It is assumed that pack reduces per capita risk each individual. We hypothesize sacroiliac articulation plays key role stabilizing predator while subduing killing U...

Twenty-six years after radiotherapy to the spine for ankylosing spondylitis a patient developed a neurofibrosarcoma initially around the left sacroiliac joint. It is likely that this was a long-term complication of the radiotherapy.

Primary bone tumours, even in very advanced stages, rarely exhibit transarticular spread. We present a case of chondrosarcoma of the ilium with destruction of the sacroiliac joint, the ipsilateral sacral ala and with sacral nerve involvement.

Brucellosis is a protean disease and should be excluded in any febrile child with a constellation of symptoms such as fever, malaise, sweating, arthralgia, and joint swelling in endemic areas. Skeletal system involvement is the most common source of complaints in brucellosis. The frequency of skeletal involvement in children is 6.4% to 73.5%. There are some controversies regarding the most comm...

UNLABELLED Hemipelvic resections for primary bone tumours require reconstruction to restore weight bearing along anatomic axes. However, reconstruction of the pelvic arch remains a major surgical challenge because of the high rate of associated complications. We used the pedicle screw-rod system to reconstruct the pelvis, and the purpose of this investigation was to assess the oncology, functio...
