Surgical Outcome of Posterior Pelvic Fixation Using S1, S2 Screws in Vertically Unstable Pelvic Ring Injury: Kwang Hee Yeo, Nam Hoon Moon, Jae Min Ahn, Jae Yoon Jeong, Jae Hoon Jang; J Korean Fract Soc 2018;31(1):9-17. Published online January 31, 2018; DOI: https://doi.org/10.12671/jkfs.2018.31.1.9

PURPOSE
Iliosacral screw fixation is an effective and less invasive method that is used widely for the definitive treatment of unstable pelvic ring injuries. On the other hand, fixation failures after iliosacral screw fixation have been reported in vertically unstable pelvic ring injuries. This study examined the surgical outcomes of posterior pelvic fixation using S1 and S2 screws in vertically unstable pelvic ring injuries.
MATERIALS AND METHODS
Between January 2011 and April 2016, 17 patients with vertically unstable pelvic ring injuries who met the minimum 1 year follow-up criteria were treated with internal fixation using posterior pelvic S1 and S2 screws. Their mean age was 43.9 years. According to the AO/OTA classification, 10 patients had C1, 6 had C2, and 1 had C3 injuries. Surgical treatments of single or multiple steps, where necessary, were performed by two surgeons. The clinical and radiologic outcomes were assessed retrospectively using radiographs and medical records.
RESULTS
Overall, 16 patients had bone healing without screw loosening; however, one patient could not maintain anterior pelvic fixation because of an open fracture and deep infection in the anterior pelvic ring. Of five patients who complained of neurological symptoms after injury, three had partially recovered from their neurological deficit. At the last follow-up, the clinical outcomes according to the Majeed score were excellent in 5, good in 6, fair in 4, and poor in 2 patients. The postoperative radiologic outcomes by Matta and Tornetta's method were excellent in 5, good in 8, and fair in 4 patients. Malposition of the S2 screw was identified in one case. The mean time to union was 14.6 weeks after surgery.
CONCLUSION
S1 and S2 screw fixation can be an effective treatment option for posterior pelvic stabilization in vertically unstable pelvic ring injuries when considering the surgical outcomes, such as screw loosening and loss of reduction.

Comparison of the Compression Hip Screw (CHS) and the Proximal Femoral Nail Antirotation (PFNA) for Intertrochanteric Femoral Fracture: Jong Min Lim, Jeung Il Kim, Jong Seok Oh, Kuen Tak Suh, Jae Min Ahn, Dong Joon Kang; J Korean Fract Soc 2010;23(4):360-366.

Abstract PDF

PURPOSE
To evaluate the radiologic, clinical results between who had intertrochanteric fracture, treated with Compression Hip Screw (CHS) and Proximal Femoral Nail Antirotation (PFNA).
MATERIALS AND METHODS
We retrospectively reviewed each 36 and 48 patients of intertrochanteric fracture which were treated with CHS or PFNA by one surgeon from January 2005 to June 2009. We evaluated mean operation time, amount of bleeding, radiologic results, and the clinical outcomes with the mobility score of Parker and Palmer, social function scoring system.
RESULTS
The mean operation time, amount of bleeding were less in the PFNA group, there were 116.7 min, 486.1 ml for the CHS group versus 87.7 min, 289.6 ml for the PFNA group. The radiologic results were not significantly different. Decrease of mobility score of Parker and Palmer, social function score were similar. Proximal migration of leg screw and perforation of femoral head was 2 case and deep infection was 1 cases in CHS group.
CONCLUSION
There were no significant differences that are clinical and radiological results in treatment of intertrochanteric fracture using the CHS and PFNA. But PFNA is less invasive device than CHS, therefore it may be useful device in elderly patients.
