To carry out the procedure general or spinal (from the waist down) anaesthetic is used. When replacing the prosthesis, general anaesthetic is used as the procedure tends to take more time.
The materials used in a hip prosthesis are intended to make movement be as similar as possible to normal joint movements. Different types of metal are used to make the implants, including: stainless steel, cobalt alloys, chromium, titanium. Some replacements are made of plastic – normally polyethylene, which is highly durable and resistant to wear and tear.
The surgery usually takes between 60 and 90 minutes to complete.
