Lumbosacral fracture-dislocation is a rare occurrence. There are more than 73 cases reported in the English literature. We report on the imaging findings and surgical treatment in a patient suffered of unilateral traumatic L5-S1 dislocation associated with severe disruption of the posterior ligamentous complex. The patient underwent open reduction and stabilization of L4-S1 vertebrae with poste...

We investigated the pathogenesis of soft-tissue contracture in club foot, using immunohistochemistry to study 41 biopsy specimens and 12 normal deltoid ligaments from cadavers. Five biopsy specimens were studied by electron microscopy (EM) to determine the presence of myofibroblasts. All 41 specimens of club foot stained positively for vimentin as against only one of the 12 control specimens. B...

own experience of considerably over 300 cases of abdominal operations, which I have had an opportunity of assisting at or observing with Dr Halliday Croom and the late Dr Angus Macdonald, I have seen nothing at all resembling this condition. The frequency of the extra-peritoneal development and growth of papillomatous ovarian tumours is well recognised by all authorities. In fact, this inter-li...

The pathomechanics, ligamentous damage, and degree of carpal instability in perilunate and lunate dislocations were analyzed by experimentally loading 32 cadaver wrists to failure. Thirteen perilunate and two lunate dislocations were produced. The mechanism of injury was extension, ulnar deviation, and intercarpal supination. These dislocations occurred in a sequential fashion due to progressiv...

BACKGROUND CONTEXT Despite significant literature associated with spinal injuries and recreational diving, few articles exist regarding competitive diving injuries, with no reports pertaining specifically to spinal injuries. As a result, a case report of a collegiate diver with C5-C6 ligamentous instability requiring operative stabilization is currently presented in addition to a review of the ...

Perilunate dislocations and perilunate fracture-dislocations usually result from high-energy traumatic injuries to the wrist and are associated with a characteristic spectrum of bony and ligamentous damage. Radiographic evaluation of the wrist reveals loss of normal radiocarpal and intercarpal colinearity and bony insult, which may be overlooked at the initial presentation. Prompt recognition i...

Verified and efficient representations of knee ligamentous constraints are essential to forward-dynamic models for prediction of knee mechanics. The objectives of this study were to develop an efficient probabilistic representation of knee ligamentous constraint using the advanced mean value (AMV) probabilistic approach, and to compare the AMV representation with the gold standard Monte Carlo (...

Background Among a general lack of awareness of scoliosis, the incidence of Adolescent Idiopathic Scoliosis (AIS) in the United Arab Emirates is not known although efforts are currently being made to remedy this. The Emirati people have a unique and well-structured culture with strong family relationships and might be considered a closed group. Consequently, there are some factors within this g...

The aim of this study was to investigate whether the ligamentous lumbar vertebral column of a macaque could potentially provide passive mechanical support to the weight of the head, upper body and forelimbs during upright sitting. The seated flexed curvature of the lumbar spine of Macaca sylvana was estimated from a photograph and was partitioned equally among the lumbar-lumbar intervertebral j...
