Abstract
Pain following total hip arthroplasty is a relatively rare event. Several series place the incidence of some degree of pain post THA at approximately 5%.
A systematic approach to determining etiology will direct treatment. Hip pain can be categorised as:
Extrinsic to the Hip
-
–
Spine +/− radiculopathy
-
–
Vascular disease
-
–
Metabolic (Paget's)
-
–
Malignancy
Intrinsic to the Hip
Intracapsular/Implant
-
Loosening
-
Sepsis
-
Prosthetic failure
-
Osteolysis
-
Instability
-
Thigh pain
-
Stem tip pain
-
Hypersensitivity/ALVAL
Extracapsular
-
Iliopsoas tendonitis
-
Snapping Hip
-
Trochanter problems (bursitis)
-
Heterotopic ossification
A full history and appropriate physical exam will direct the clinician. The use of routine radiographs, blood tests, and special tests (i.e., blood metal ions, advanced imaging techniques) will be discussed I detail.
