摘要:
A bone screw for pelvic bone fixation, the bone screw comprising an elongate body having a first end which is threaded for engaging at least one bone in the pelvic region, a second end comprising a screw head, and at least one opening across the length of the elongate body for adjustably receiving a fastening means to limit movement of the bone screw away from the engaged bone in use, wherein the at least one opening is shaped such that the position of the fastening means relative to the elongate body of the bone screw can be adjusted. A system for bone fixation in the pelvic region includes the bone screw and the fastening means.

A device comprises an arm cover to be positioned under the arm before being closed thereover, a shoulder strap to be positioned under the shoulder and adapted to wrap the shoulder when attached, over the shoulder, to the closed arm cover and a longitudinal strap to be fixed to the table opposite to the head. The longitudinal strap can apply tension on the shoulder strap when shortened. A method for installing a device on an immobilized patient comprising positioning an arm cover under the arm and a shoulder strap connected to the arm cover under the shoulder, closing the arm cover over the arm and attaching the shoulder strap, over the shoulder, to the closed arm cover, fixing an end of a longitudinal strap, connected to the arm cover, to the table opposite to the head and pulling on the longitudinal strap to apply tension on the shoulder strap.
摘要:
A series of ortheses for the treatment of scoliotic deformities are each adapted for obliquely applying dynamic derotational forces on the thorax and lumbar spine of the user in opposite directions combined with a kyphosing action on the thorax and a lordosing action on the lumbar spine. The orthoses are designed in order that the correcting forces can be applied on the user's trunk with various degree of mechanical force while allowing for complete or partial mobility of the trunk. The various orthoses can treat small, moderate and substantially severe deformities which are supple or rigid. A supple orthosis for small and supple curves comprises a thoracic garment encircling the upper thorax, short pants to provide a grip around the pelvic girdle and the upper thighs, and upper and lower semi-elastic straps having supple thoracic and lumbar pads, respectively, attached respectively to the garment and the pants. The straps which connect the pads encircle obliquely the trunk for exerting the derotational forces and the kyphosing and lordosing actions. For moderate and supple curves, semi-rigid thoracic, lumbar and pelvic pads are incorporated in the orthosis. For rigid curves, the orthosis comprises a supple plastic shell encircling the pelvic girdle, a vertical member extending posteriorly and upward from the shell and comprising thoracic and lumbar pads. Semi-elastic strap means extend anteriorly between the pads while encircling obliquely the trunk. The vertical member can be integral with the shell or, for more rigidity, can consist of metallic member attached to the shell.

摘要:
A surgical guiding instrument for use with a drilling tool and a bone engaging element, comprises a support on which the bone engaging element is adapted to be mounted for engaging a region of a bone to orient the support with respect thereto. The guiding instrument further includes a drill guide mounted to the support and defining a passage for guiding the drilling tool so as to prevent deviation of the drilling direction. The drill guide can be angularly adjusted relative to the bone engaging element in the plane of the support by simply sliding the drill guide on an arc of circle defined by the support.
