Summary
A hip implant screw dislodged and entered the pelvic cavity, likely due to technical issues, osteoporosis, and re-injury. Removal is possible via the original incision, but laparotomy may be necessary.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Trauma care
Background:
- Hip fracture fixation commonly uses sliding screws and plates.
- Osteoporosis increases the risk of implant complications.
- Technical failures can compromise surgical outcomes.
Observation:
- A case report details a sliding screw disengaging from its plate.
- The screw penetrated the acetabulum, entering the pelvic cavity.
- The patient had a history of osteoporosis and experienced new trauma.
Findings:
- The dislodged screw caused significant internal displacement.
- Screw removal through the acetabular incision is feasible.
- Potential for intra-abdominal or pelvic organ injury exists.
Implications:
- Highlights the importance of surgical technique in hip fixation.
- Suggests considering patient-specific factors like osteoporosis.
- Emphasizes the need for preparedness for complex revision surgeries, including laparotomy.
