The Treatment of Intertrochanteric Femoral Fracture with Proximal Femoral Nail Antirotation: Jong Won Kim, Hyun Soo Park, Young Soo Jang, Jae Hyuk Choi, Sung Ju Bae, Chan Il Bae; J Korean Fract Soc 2012;25(4):257-262. Published online October 31, 2012; DOI: https://doi.org/10.12671/jkfs.2012.25.4.257

Abstract PDF: PURPOSE
This study was performed to evaluate the results of treating intertrochanteric fracture with proximal femoral nail antirotation (PFNA).
MATERIALS AND METHODS
We performed PFNA on 41 intertrochanteric femur fracture patients from May 2008, to August 2010. We analyzed the operation time, blood loss, recovery of ambulatory function, T-score, the tip apex distance (TAD), the sliding distance of the blade, neck-shaft angle, and complications.
RESULTS
The mean operation time was 51 minutes and the mean amount of blood loss was 350 ml. The time to ambulation averaged 7.2 days. Thirty-two cases (79%) recovered their previous walking status at 6 months after operation. The average T-score was 3.3 and TAD was 12.3 mm (8.6~27 mm). 35 cases (87%) achieved acceptable reduction. The average amount of PFNA blade sliding was 3.3 mm. The neck-shaft angle was changed 2.6 degrees varus displacement at the final follow-up. There was one case of nonunion due to tuberculosis infection.
CONCLUSION
The findings from this study indicate that PFNA is a useful and reliable choice for the treatment of intertrochanteric fracture of the femur.

The Importance of Position of the Distal Fragment in Intertrochanteric Fracture of the Femur using Compression Hip Screw: Jong Deuk Rha, Hyun Soo Park, Young Bong Park, Chang Suk Lim, Seung Woo Kim; J Korean Soc Fract 2003;16(4):447-455. Published online October 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.4.447

PURPOSE
We reviewed the amount of impaction and the change of neck shaft angle of intertrochanteric fracture of the femur which were treated with compression hip screw according to the fracture type and the displaced state of the distal fragment.
MATERIALS AND METHODS
There were 50 patients who had at least six months follow up, 13 men, and 37 women who were treated from January 1995 to December 2000. We have analysed the amount of impaction (measurement of the ratio between screw length and screw outside barrel length) and the change of neck shaft angle according to the fracture type and the displaced state of the distal fragment. The results were assessed statistically.
RESULTS
The fracture healing was achieved in about 13 weeks. There were 36 stable fracture types and 14 unstable fracture types by Evans classification. The most common osteoporotic singh index was grade II. The mean impaction amount of the fracture site was 5.4 mm and the mean neck shaft angle change was 1.5degrees of varus angulation. The mean tip apex distance was 32 mm. There was no case of lag screw penetration into the joint. There was significant difference in result according to the displaced state of the distal fragment. The amount of impaction was less in cases that anatomically reduced or got the posterolateralization of the distal fragment.
CONCLUSION
The results of our study indicate that the anatomical reduction and posterolateralization of the distal fragment could reduce the amount of impaction and the change of neck shaft angle. We advise that the position of the distal fragment in intertrochanteric fracture of the femur is very important to reduce the failure.

Flexion-type Humerus Supracondylar Fractures in Children: Jae Do Kang, Kwang Yul Kim, Hyung Chun Kim, Moon Sup Lim, Shin Kwon Choi, Hyun Soo Park; J Korean Soc Fract 2002;15(4):601-606. Published online October 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.4.601

Abstract PDF: PURPOSE
We investigated the treatment modality and clinical results in flexion-type supracondylar fractures of the humerus in children.
MATERIALS AND METHODS
11 cases of flexion-type supracondylar fractures of the humerus(3 type I, 5 type II, 3 type III) were treated, 3 fractures(3 type I) with extension cast, 6 fractures(5 type II, 1 type III) with two lateral percutaneous K-wire fixation, 2 fractures(2 type III) with open reduction and crossed pin fixation. The K-wire were removed after 4-6 weeks of operation and the follow-up period ranged from 12 months to 26 months, averaging 18 months.
RESULTS
By Flynn 's functional and cosmetic criteria, nine cases were good and excellent results, one case (type III with two lateral percutaneous pin fixation) is fair result.
CONCLUSION
As the same methods of the extension-type supracondylar fractures, the K-wire fixation is useful method in the treatment of flexion-type supracondylar fractures of the humerus in children.

Assessment of the Stability of the Isolated Lateral Malleolar Fracture: Woo Chun Lee, Hyun Soo Park, Young Kil Han, Jang Woon Rim, Jong Deuk Rha; J Korean Soc Fract 1998;11(4):873-879. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.873

Abstract PDF: Recent advances in the understnading of the biomechanics of the ankle have given rise to the clinical uncertainty about the indications for the operative treament of isolated fractures of the lateral malleolus. If deltoid ligament injury is associated, it may be unstable and operation may be indicated. This study was done to determine if we are able to assess the stability of the isolated lateral malleolus fracture based on the fracture patterns seen on radiographs and clinical findings. 37 patients with malleolar fracture of the ankle were treated at Hanil General Hospital by open reduction and internal fixation from Dec. 1996 to Jan. 1998. Lauge-Hansen classification was tried in all cases to determine if it could be applied. Stress test under anesthesia on 10 isolated lateral malleolar fracture patients with clinical findings of injury on the deltoid ligament area, whose medial clear space were normal or widened less than 2 mm on initial film. Exploration of the deltoid ligament was performed in 6 of above 10 patients There were 21 supination-external rotation type injuries, 2 supination-adduction injuries, 1 pronation-abduction injury and 13 fractures could not be clearly categorized into specific group. In 6 among 13 unclear cases, there were short oblique fracture lime indicating pronation injury, but direction of the fracture line could not be clearly determined. In 4 cases, direction of the fracture lime indicated pronation injury, but the length of the fracture line was too long. In 3 cases, both the direction and length of the fracture line was indeterminate. The stress test on 10 isolated lateral malleolar fraactures with clinical findings of deltoid injury revealed less than 2 mm widening in 7 cases, more than 2 mm widening in 3 cases. In 3 cases with less than 2 mm widening, tearing of anterior third of superficial deltoid was confirmed by exploration. In 3 cases with more than 3 mm widening, partial rupture of the deep deltoid was observed in 2 cases and anterior third of superficial deltoid was torn in 1 case. We suggest that we cannot clearly assess the stability of isolated lateral malleolar fracture either by fracture patterns or clinical findings, so stress test can be considered in determining the stability.

Interlocking Intramedullary Nailing of Femoral Shaft Fractures in Adolescents: Chil Soo Kwon, Jong Kuk Ahn, Jin Hyok Kim, Byung Hyun Jung, Yerl Bo Sung, Hyung Jin Jung, Jong Deuk Rha, Woo Chun Lee, Hyun Soo Park, Myung Ho Lee, Bu Maan Kim; J Korean Soc Fract 1996;9(4):914-920. Published online October 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.4.914

Abstract PDF: Although treatment of femoral shaft fractures by traction and casting satisfactory in young children, it is less useful in obtaining and maintaining satisfactory alignment in adolescent patients. Residual angulation, malrotation. and leg length inequality is well documented. The options for surgical treatment of femoral shaft fractures in adolescents include extemal fixation, plate fixation, and intramedullary nailing. Surgical treatments carry the-risks of growth plate damage and infection, but these risks are very low. Recently, it is generally anepted that adolescent femoral shaft fractures are preferably treated by intramedullary nailing with care taken to avoid damaging the distal femoral physis. The authors experienced 9 femoral shaft fractures in 8 patients treated with interlocking intramedullary nails from August 1989 to May 1994, and followed up for more than 18 months(range from 18 to 45 months). The results were as follows: 1. There were 6 cases in male, 2 cases in female. Average age at the time of injury was 13 years(range, 11-14). 2. All fractures were united, and the nails were removed at an average 13.3 months after operation: no refracture or femoral neck fracture has since occured. 3. None had angular or rotational malunions, infection and avascular necrosis of femoral head. The average leg-length discrepancy at the last follow-up was 0.5cm(range, 0-1.0cm) and all were clinically acceptable. Coxa valga due to premature closure of trochanteric apophysis was not found. The average femoral neck-shaft angle was 133(130~138) at the last follow-up. So, interlocking intramedullary nailing is a reasonable alternative for the treatment of femoral shaft fracture in adolescents.

Treatment of Patella Fracture Using Wiring Method: Kwon Ick Ha, Sung Ho Hahn, Min Young Chung, Hyun Soo Park; J Korean Soc Fract 1989;2(2):229-233. Published online November 30, 1989; DOI: https://doi.org/10.12671/jksf.1989.2.2.229

Abstract PDF

To determine whether any of the commomly used wiring technique are rigid enough to allow early motion in treatment of patellar fracture. Twelve cases of extensively commivuted and displaced patellar fracture were treated using wire technique (circumferential combined tension band wiring) at N.P.H. from April 1987 to April 1989. This method has advatages of simple and rigid fixation and results were satisfactory.
