Abstract
BACKGROUND

Postoperative pain following total hip arthroplasty (THA) may occur in a few patients but may pose a significant challenge to surgeons if the etiology is not identified. Herein, we report the case of a patient who developed late-onset pain following THA due to screw penetration of the iliopsoas tendon.

CASE SUMMARY

We report the case of a 77-year-old man who developed inguinal pain 7 years after THA. While the symptoms resembled that of iliopsoas impingement by the acetabular cup, the pain resolved only when the supplementary acetabular screw protruding through the ilium was decompressed. Decompression was performed using the pararectus approach. The patient was able to ambulate pain-free immediately after surgery.

CONCLUSION

A protruded screw through the ilium may penetrate the iliopsoas muscle, causing pain following THA. Pain may resolve with the decompression of the protruded screw.

Keywords: Acetabular cup, Iliopsoas impingement, Para-rectus approach, Screw penetration, Total hip arthroplasty, Case report

Core Tip: The acetabular screws are mostly positioned in the posterolateral quadrant and rarely protrude through the anterior ilium. However, when supplementary screw is protruded anteriorly and penetrate through iliopsoas muscle, the symptom may resemble that of the iliopsoas impingement by acetabular cup. Instead of removing the entire screw, which would require dislocation of the hip and disassembly of the ceramic liner, flatten the protruded portion of the screw with the para-rectus approach may relieve the symptom.
