Introduction Percutaneous screw fixation is considered the best option in unstable pelvic fracture with severe soft tissue injury. However, fixation technique at the level of S3 has not been well established. This paper showed the feasible surgical technique of S3 screw insertion in unstable pelvic fracture with severe soft tissue injury. Methods We reported 2 cases of unstable pelvic injury of an 11 years old boy with Marvin-Tile (MT) C1 pelvic fracture with sacroiliac (SI) joint disruption, skin avulsion and Morel-Lavallée lesion. Second case was 30 years old male with open pelvic fracture MTB2 and vertical sacral fracture Denis zone I with Morel-Lavallée lesion, intraperitoneal bladder rupture, infected laparotomy wound dehiscence. We performed percutaneous screws insertion on both pubic rami and IS screw on S1 and S3 to both cases. Functional outcome was evaluated using Majeed and Hannover pelvic score. Results All patients survived and had good reduction with no residual displacement on SI joint. The former case at 21-month follow up presented with excellent outcome (100/100) by Majeed score and very good outcome (4/4) by Hannover score; while the latter case, at 18-month, present with good outcome (85/100) Majeed score and fair outcome (2/4) Hannover score. Conclusions Percutaneous screw fixation at the level of S3 is feasible and can be inserted in S3 level by sacroiliac type and sacral type with minimal soft tissue intervention and good functional outcome.
