Unstable Intertrochanteric Fracture Treated with ITST: A Comparative Study between Groups with and without Comminution of Greater Trochanter: Kyung Sub Song, Sang Ho Lee, Seong Hun Jeong, Su Keon Lee, Sung Ha Hong; J Korean Fract Soc 2014;27(1):36-41. Published online January 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.1.36

Abstract PDF: PURPOSE
To evaluate whether the radiological and clinical results of treatment with intertrochanteric/subtrochanteric (ITST) nail on unstable intertrochanteric fractures are combined with comminution of the greater trochanter or not.
MATERIALS AND METHODS
We reviewed the results on 210 cases of unstable intertrochanteric fractures (grouped 88 patients with comminution of greater trochanter [GT] and 122 patients without comminution of GT) treated with ITST nail from January 2007 to October 2011, which was to be followed-up for more than 12 months.
RESULTS
The mean union time was 15.2 weeks in the study group (combined with comminution of GT). The mean union time was 14.7 weeks in control group (no comminution of GT). The lag screw sliding was 8.7 mm in the study group and 7.2 mm in the control group. Changes of neck-shaft angle was 4.2degrees in study group and 4.1degrees in control group. Tip-apex distance was 17.4 mm in study group and 16.4 mm in control group. The complications were 4 cases in each study group and control group. The clinical results checked by Skovron recovery scores decreased similarly in both groups, 73.7% in study group and 76.5% in control group. There were no significant differences in both groups according to radiological and clinical results.
CONCLUSION
The comminution of great trochanter does not affect on the radiological and clinical results when using the ITST nail of unstable intertrochanteric fractures.

The Comparison between ITST(TM) (Intertrochanteric/Subtrochanteric) & DHS (Dynamic Hip Screw) in Unstable Femur Intertrochanteric Fracture: Ho Seung Jeon, Byung Mun Park, Kyung Sub Song, Hyung Gyu Kim, Jong Ju Yun; J Korean Fract Soc 2009;22(3):131-137. Published online July 31, 2009; DOI: https://doi.org/10.12671/jkfs.2009.22.3.131

PURPOSE
To evaluate between DHS and ITST nail (2nd generation) on the treatment of unstable femur intertrochanteric fracture in patients over 70 years old.
MATERIALS AND METHODS
61 cases of unstable intertrochanteric fracture (grouped 37 patients with DHS and 24 patients with ITST) who were taken the operation from Mar. 2003 to Sep. 2007 were analysed regarding to union time, sliding length of lag screws, operation time, blood loss, postoperative complications and functional recovery score by Skovron.
RESULTS
The mean union time was 14.7 weeks in study group (ITST). The mean union time was 16.2 weeks in control group (DHS). The lag screw slidings were 7.2 mm in study group and 8.7 mm in control group. The operation times were 57.9 min in study group and 76.9 min in control group. The amount of blood loss were 67.7 ml in study group and 227.4 ml in control group. The complications were 4 cases in study group and 4 cases in control group. The Skovron recovery scores were 76.5% in study group and 73.7% in control group.
CONCLUSION
From a practical point of short operation time, less amount of bleeding and less complication, author think that the ITST nail is useful implant for treatment of unstable femur intertrochanteric fracture in patient of old age.

Arthroscopically Assisted Fixation of Intraarticular Distal Radial Fractures: Won Young Lee, Byung Mun Park, Dae Eu Lim, Kyung Sub Song, Jung Woo Hong; J Korean Soc Fract 2003;16(3):399-406. Published online July 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.3.399

Abstract PDF

PURPOSE
To investigate the results of arthroscopically assisted reduction of intraarticular fracture of distal radius with percutaneous K-wires and external fixation.
MATERIALS AND METHODS
We reviewed 12 intraarticular distal radial fractures of 11 patients treated arthroscopically assisted reduction in Orthopedic Department of Sung-Ae hospital between January, 2001 and August, 2001. The mean length of follow-up was 14 months. Analysis of them revealed that B3 was 1 case, C2 4 cases and C3 7 cases according to the AO classification. All cases were treated by 2.7 mm arthrosopic devices and percutaneous K-wires pinning with external fixation, but additionally invasive reductional technique was not used. We removed the osteochondral flap in the joint space and detected the carpal ligaments and triangular fibrocartilage complex tears but not treated. The K-wires were removed at 4 weeks, external fixation was 7 weeks, respectively.
RESULTS
The mean active range of movement in the affected wrist was total arc of the flexion-extension 72% of the opposite side. Radiographically mean volar tilt, radial inclination and radial length were 5.7 degrees, 22.4 degrees, and 12.3 mm. The mean articualar step-off was 2 mm or less. Post-operative compartment syndrome and fracture collapse were not occured during follow-up period. According to the Gartland and Werley demerit-point system, eleven cases were a excellent or good and one was a fair result.
CONCLUSION
Arthroscopically assisted fixation is a useful method for reducing the soft tissue injuries and preventing the articular surface incongruency by anatomically reduction in cases of intraarticular comminution.
