Figures & data
Figure 1. Preoperatively, advanced metastatic destruction of the right acetabulum with a pathological fracture and medial and cranial dislocation of the acetabulum.
Figure 2. Periacetabular reconstruction with modified Harrington technique and total hip replacement. Unthreaded pin is marked with an arrow.
Figure 3. Six months postoperatively: note the appearance of the most medial pin projecting beyond the medial acetabular border (marked with an arrow). There was no definite pin migration at that point.
Figure 4. The migrated pin projecting into the pelvic cavity.
Figure 5. CT scan 10 months after surgery; transverse plane of the pelvis just below the level of the hip joint. Note the projection of the tip of the Steinmann pin crossing the narrow space between rectum and prostate, overlapped with mental artefacts of the pin.
