The unstable total hip replacement

Download a copy of the Scientific Article here

Dislocation is one of the most common complications of total hip replacement – dislocation rate of 3.2%.

Despite increased experience with hip replacement, the overall rate has not yet changed. The risk of first-time dislocation as a function of time after the surgery is not well understood. But the risk of dislocation is highest during the first few months after hip replacement; however, first-time late dislocation can also occur many years after replacement.

In this paper, several risk factors were highlighted:

• surgical approach
• the diameter of the head
• impingement
• component malposition
• insufficient abductor musculature

And also treatment options:

• long-term bracing after closed reduction
• component reorientation
• capsulorraphy
• trochanteric advancement
• increasing offset
• exchange of the modular head and the polyethylene liner
• insertion of constrained liner.
