Complications of total hip ~~joint replacements~~arthroplasty are common and are essential for the radiologist to be aware in the assessment of the radiographs with hip prostheses. They are many and can occur at various time intervals following the initial surgery:.

aseptic loosening: considered to be the most common indication for revision surgery ^1,2,4
infection of hip prostheses ^5,6
particle disease / histiocytic reaction / aggressive granulomatosis
fracture
dislocation (~5% of all replacements ⁴)
- dislocation of femoral head out of the cup: component dissociation
- dislocation of the entire acetabular cup
- dislocation of stem
malpositioning
- creep: can lead to protrusio acetabuli
- polyethylene wear eccentric position of the femoral head component within the acetabular component
heterotopic bone formation
metal-on-metal pseudotumour
pseudobursae formation ²
abductor ~~tendon~~muscle/tendon dysfunction e.g. tears
stress shielding
trochanteric bursitis
revision total hip arthroplasty
general post-orthopaedic surgical complications
- haemorrhage
- wound complications e.g. dehiscence
- thromboembolism, i.e. deep vein thrombosis and pulmonary embolism
- vascular injury
- neurological deficit
- death

A standardised list of complications post total hip arthroplasty was developed by consensus by The Hip Society. This would enable consistent standardised reporting of complications ⁸.
