Migration of the Gamma Nail Neck Screw into the Pelvis with Bladder Damage

Medial migration of the cervical screw is a frequent complication of Gamma nails and is observed in 4.3% - 6% of cases. The reasons are a violation of the surgical technique of osteosynthesis of a trochanter fracture, including an unrepaired fracture, a breach of the insertion point of the fixator, and a suboptimal position of the cervical screw. However, the migration of the Gamma nail neck screw into the pelvic cavity is sporadic, and only a few cases have been published in the literature.
