The improved positioning device, for use in hip, pelvis or bariatric surgery, securely and safely supports a morbidly obese patient lying in the lateral decubitus position at one side of an operating table so the surgeon may stand close to the anterior side of the patient. The support device includes a double-ended bracket having a pair of oppositely positioned padded end portions secured to an angular bracket post adapted to securely mount to an operating table via a question mark-shaped bracket. The angular bracket arm vertically adjusts to support the patient on one side, with the padded end portions applied to bony prominences such as the symphysis pubis and the lower side anterior superior iliac spine. The support device is used in combination with a posterior pelvic support plate, and a pair of anterior-posterior chest support plates to retain the patient in a secure and stable manner during surgery.

An improved anterior pelvic support device is provided for use in securely and safely positioning a patient during a surgical procedure, such as hip or pelvis surgery. The support device comprises a double-ended bracket arm having a pair of padded support members at opposite ends thereof and adjustably carried on a bracket post adapted for secure mounting as by clamping onto an operating table. The bracket arm is adjustably positioned to support the patient lying on one side in a lateral decubitis position, with the padded support members applied to bony prominences particularly such as the symphysis pubis and the lower side anterior superior iliac spine. The support device is used in combination with a posterior pelvic support plate, and a pair of anterior-posterior chest support plates to retain the patient in a secure and stable manner during surgery.

An alignment fixture for taking X-ray images of a patient, such as an image of the patient's hip region preparatory to hip arthroplasty. The alignment fixture comprises multiple support legs for resting on the patient at known positions, such as upon known bony prominences, in combination with aiming marks used for anatomically aligning the patent's pelvis under an X-ray beam. A ruled grid plate on the fixture is adjustably positioned between an image beam source and the patient, as a function of patient thickness in the pelvic region, so that a ruled grid overlays the anatomical region of interest and exhibits an apparent parallax image magnification corresponding with the parallax image magnification of a centerline of the anatomical region, such as the hip joint. X-ray images taken by use of the alignment fixture can be viewed and/or scaled to select a properly sized prosthesis for the specific patient.

A bone plug is provided for insertion into the medullary canal of a patient bone during orthopedic surgery, wherein the bone plug restricts or prevents passage of bone cement introduced under pressure into the medullary canal. The bone plug includes a generally cylindrical member formed from a biocompatible material such as polyethylene and having sets of distal and proximal fins. The distal fins are defined by a spiral thread set at an angle to extend distally, to bend to accommodate the shape of the medullary canal and thereby anchor the bone plug by biting into patient bone, whereas the proximal fins flex during plug insertion to extend proximally and thereby seal against bypass flow of bone cement past the bone plug. An insertion tool is also disclosed, for use in placing the bone plug during a surgical procedure, such as hip arthroplasty.

The bone plug comprises a generally cylindrical member formed from a biocompatible material such as polyethylene and having sets of distal and proximal fins formed thereon. The bone plug is installed with an insertion tool that can be readily manipulated to orient the distal fins to define distally presented outer edges to anchor the bone plug by biting into patient bone, whereas the proximal fins are oriented to define proximally presented outer edges to seal against bypass flow of bone cement past the bone plug.
