Abstract PDF: PURPOSE
The goal of our study was to evaluate the usefulness and results of the Interlocking Compression Nail in femoral shaft stable fractures.
MATERIALS AND METHODS
The 87 patients, 88 cases, who were underwent internal fixations with interlocking compression nail for the stable fracture of the femoral shaft were evaluated. The majority of the causes of injury was traffic accident and the majority of location of the fractures was middle one thirds. The classification of the fracture using Winquist-Hansen classification showed that grade 0 were 23 cases(26.1%), grade 1, 47 cases(53.4%) and grade 2, 18 cases(20.5%). We used ICnail(Osteo, Switzerland) that can actively compress the fracture gap, maximum 10mm.
RESULTS
We used active compression in 63 cases(71.6%) and the mean length of compression was 2.3mm(range 1-5mm). The bone union was seen in 63 cases(71.6%) at postoperative 4 months and in 87 cases(98.9%) at postoperative 6 months. There was one case of delayed union, but there were no nonunion, infection, leg length discrepancy, and angular or rotational deformity, disturbing the daily activity.
CONCLUSION
The interlocking compression nail can reduce the fracture gap easily and effectively using compression screw by active interfragmentary compression. Thereby promote fracture healing and postoperative stability at the fracture site can be obtained, so early weight bearing is possible. Especially, this is recommendable useful method for femoral shaft stable fracture.

Interlocking Compression Nails for the Treatment of Acute Tibial Shaft Fractures: Sang Wook Bae, Ho Yoon Kwak; J Korean Soc Fract 2000;13(1):74-80. Published online January 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.1.74

Abstract PDF: PURPOSE
To evaluate the differences between interlocking compression nail and ordinary compression nail in the treatement of acute tibial shaft fractures ,ATERIALS AND METHODS: From March, 1995 to November, 1998, 67 patients were treated with intramedullary nail for the acute tibial shaft fractures. Among them, 27 cases treated with interlocking compression nails and 22 cases, with ordinary interlocking nails were analyzed in terms of average union time, complications and functional results.
RESULTS
One tibial shaft treated with interlocking compression nail failed to unite. Average union time was 14.4 weeks in the group treated with interlocking compression nails, 14.2 weeks, with ordinary interlocking nails. Functional results were graded as excellent and good in 85% in the group treated with interlocking compression nails, 90%, with ordinary compression nails.
CONCLUSION
There was no difference in the treatment results between the groups treated with interlocking compression nails and ordinary interlocking nails.

Treatment of the Femoral Shaft Fractures with Interlocking Compression Nail: Sung Taek Jung, Taek Rim Yoon, Jong Keun Seon; J Korean Soc Fract 1998;11(2):281-287. Published online April 30, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.2.281

The results of treatment of femoral shaft fractures with interlocking compression nail, the third generation nail, were evaluated to determine the incidence of union of the fracture & clinical usefulness. Fifty-three femoral fractures that had been treated by interlocking compression nailing between February 1994 and March 1996 and had been followed for more than twelve months were included in this study. forty-eight cases were fresh closed fracture and five, fresh open fracture. The results were as follows 1. According to Winquist-Hansen classification, 25 cases were type I, 13 type II, 7 type III, 5 type IV, 3 type V. 2. Union occurred in 52(97%) of 53 femoral shaft fractures. The mean fracture union period was 18.1 weeks with a range of 10 to 32 weeks. 3. Postoperative complication were delayed union(5 cases), leg length discrepancy(2 cases) and nonunion(1 case). We concluded that interlocking compression nailing for femoral shaft fracture seems to promote the fracture healing process without conversion to dynamic intramedullary fixation.

Interlocking Intramedullary Nailing of the Femoral Shaft Fracture: A Comparison between Gross-Kempf Nail and Interlocking Compression Nail: Ki Soo Kim, Yong Soo Choi, Chae In Lim, Yang Min Chung; J Korean Soc Fract 1995;8(4):767-776.

Abstract PDF: Various designs of interlocking intramedullary nailing systems allowing closed nailing techniques have been used in the treatment of femoral shaft fractures, but there are little objective data available to compare their performance. The authors reviewed 58 patients of femoral shaft fractures which were treated at Kwang ju christian hospital from April 1992 to June 1994. The Gross-Kempf nail was used in 39 patients and the Interlocking compression nail was used in 19 patients. The purpose of this study is to determine if there are any significant difference in the application, ease of use or clinical outcome. The average follow up period up period was 21.5 months (range 12 to 31 months) and the results were as follows. 1. Two nails have similar indication for use, but G-K nail was more satisfactory for proximal fractures of the femur and I-C nail was used as a compression nail with application of one proximal interlocking screw in oval hole in simple stabilizable fractures(Winquist Hansen type I and / or type II). 2. In the G-K naiBing group, the partially threaded screw of distal locking gaining purchase in only one cortex comes loose more often and backs out more frequently. In the I-C nailing group, the fully threaded screw of distal locking is able to fail of screw because of smaller core diameter of the screw. Successful distal locking is not only dependent upon strength of transverse screw, but also upon achieving cortical fixations with threads. 3. Complications seemed to be failure of operative principle and postoperative care rather than any intrinsic problems with the nail themselves.
