The Motown Corkscrew: A Simple Method for Extraction of an Embedded Intra-Articular Foreign Body.

CASE: A 17-year-old boy presented after a gunshot wound; computed tomography showed a comminuted posterior-wall acetabular fracture and a bullet 90% embedded. Through a Ganz surgical dislocation, a standard 2.5 mm drill bit was advanced 8 to 10 mm into the projectile, its flutes functioning as a self-tapping screw to rock and extract the bullet en bloc, followed by trochanteric osteotomy fixation. He regained painless full activity by 2 months; 33-month imaging confirmed durable union with no osteolysis.

CONCLUSION

The "Motown Corkscrew" technique provides a cost-neutral, controlled method to remove bone-embedded intra-articular bullets while preserving articular structures.
