چکیده

A method is described of measuring radiological subsidence of a femoral prosthesis in relation to the femur after total hip arthroplasty. The method depends on measuring the distance from the tip of the femoral prosthesis to a fixed point in the bone. Subsidence after the use of a conventional design of femoral stem is compared with that after the use of a stem with a dorsal flange (Cobra). A significant reduction in the incidence and amount of subsidence was found when using the dorsal flange. There was also a notable absence of transverse fractures involving the cement near the tip of the stem, which occurred in 26 per cent of the cases using a conventional prosthesis.

Hip Arthroplasty and its Revision in a Child: Case Report and Literature Review

Juvenile idiopathic arthritis is the leading cause of hip replacement in young children. However, arthroplasty in this population is challenging with several concerns about quality of the growing bone, young age for revision surgery, and difficulties in potential several revisions. In this study we introduce a case of a 12-year old who is one of the youngest patients to undergo revision hip art...

A Single Femoral Component for All Total Hip Replacements Performed by a Trust? Does This Affect Early Clinical and Radiological Outcomes?

Background: Hospitals may be under pressure to implement cost saving strategies regarding prosthesis choice. Thismay involve the use of components which are not the first preference of individual surgeons, or those they have littleexperience with. We aim to examine the effect of standardizing the type of femoral stem used in a single trust, anddetermine whether this is safe practice, particular...

Evaluation of an expandable stem total hip replacement system.

The expandable nail concept uses high-pressure saline to inflate the diameter of a cylindrical implant to achieve fixation within the medullary canal of bone. Expandable nails are used clinically in a number of fracture management applications and have been more recently developed as a femoral component for total hip replacement. In this study, the expandable total hip replacement stem design w...
