Fig. 17.4. ( a , b ) Metal corrosion from metal-on-metal hip implant or modular
components can lead to painful adverse local tissue response (ALTR) and socalled
“pseudotumors”.
cases done through an anterior approach show transient irritation of the
iliopsoas tendon that often subsides without aggressive intervention.
Stress fractures around cementless acetabular component, hematomas,
impingement, loosening, or leg length discrepancy that aggravates
preexisting spinal disease can all lead to groin pain. Metal corrosion
from metal-on-metal hip implants or modular components can lead to
painful effusions and so- called “pseudotumors” (Fig. 17.4 ) [26 , 27 ].
Lastly, groin pain in a patient with a previous hip fracture treated with a
hip replacement may in fact have a partial hip replacement, also known
as a hemiarthroplasty. A good number of these patients, deemed “low
demand” and given this type of implant, go on to have groin pain due to
acetabular degeneration, either preexisting or progressive since surgery.
