Lateral Positioning for Proximal Femoral Nailing of the Intertrochanteric Fracture: Surgical Technique: Kwan Hee Lee, Hoon Jeong, Jong Kyoung Ha, Yong Ju Kim, Won Hee Jang; J Korean Fract Soc 2011;24(1):79-82. Published online January 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.1.79

In the treatment of intertrochanteric fractures, most of intramedullary nailings are performed on a fracture table in supine position. In supine position, however, soft tissue mass of the patients and drapes make it difficult to access to the piriformis fossa and to straighten the trajectory of reamer and nail insertion. To resolve these problems, we have treated twenty intertrochanteric fractures in lateral position on the general operation table with IM nail. Adjustment of the position of lag screw in femoral head was done with the technique that overlaps the shadows of the femoral head, nail and targeting guide in the lateral view. Because the entire injured limb can be moved readily, it was easy to reduce fracture and to convert to open procedure. In cases likely that the fracture table is unavailable in which patients are obese, have short stature or are amputated, and that open procedure is strongly likelihood, lateral position will be helpful technique in the treatment of intertrochanteric fractures with IM nail.

Comparative Study of Intramedullary Nailing and Plate for Metaphyseal Fractures of the Distal Tibia: Hoon Jeong, Jae Doo Yoo, Young Do Koh, Hoon Sang Sohn; J Korean Fract Soc 2007;20(2):154-160. Published online April 30, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.2.154

Abstract PDF

PURPOSE
To compare the radiological and clinical results between intramedullary nailing and plate fixation in the treatment of distal tibial fractures.
MATERIALS AND METHODS
19 cases of distal tibial metaphyseal fractures within 4 cm of the ankle joint line were enrolled. Ten patients were treated with interlocking intramedullary nail and the others with plate and screws.
RESULTS
The mean union time was 14 weeks in nailing group and 16 weeks in plate group. The average angulation in AP view was 4.1 degrees in nailing group and 3.1 degrees in plate group. The average angulation in lateral view was 1.7 degrees in nailing group and 2.7 degrees in plate group. The rotational deformity was 2.8 degrees in nailing group and 1.7 degrees in plate group in average. There was no implant failure and soft tissue problem.
CONCLUSION
There was no difference in clinical and radiological results between intramedullary nailing and plate in the treatment of the distal tibial fractures and, considering the preservation of the soft tissue, the intramedullary nails are a reliable method for managing distal metaphyseal fractures of the tibia.

Extra-articular Triplane Fracuture of the Distal Tibia in Children: Yeo Hun Yun, Hoon Jeong, Yi Kyoung Shin, Sung Gu Yeo; J Korean Fract Soc 2005;18(4):459-461. Published online October 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.4.459

Abstract PDF: PURPOSE
To demonstrate the effectiveness of the conservative treatment which was introduced to the extraarticular triplane fractures of the distal tibia.
MATERIALS AND METHODS
We reviewed radiographs and medical records of eight patients with extraarticular triplane fractures of the tibia. Four patients were treated with closed reduction and internal fixation and the others with closed reduction and plaster.
RESULTS
In all patients, the union of fractures was obtained. Although the physes were closed early, there was no angular deformity or leg length discrepancy.
CONCLUSION
In case of extraarticular triplane fracture, except for open fracture or failure of closed reduction, conservative treatment yield good result.

Treatment of Vertebral Pseudarthrosis after Compression Fracture: Young Do Koh, Hoon Jeong; J Korean Fract Soc 2004;17(2):191-196. Published online April 30, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.2.191

Abstract PDF: PURPOSE
To clarity the features of vertebral pseudarthrosis and to evaluate the efficacy of posterior instrumentation and fusion in treatment of it.
MATERIALS AND METHODS
Twelve patients with severe back pain and intravertebral pseudarthrosis showing vacuum phenomenon were treated by in situ posterior instrumentation and fusion. The kyphotic angle of pre- and post-treatment was measured on a lateral radiograph. MRI was performed in all patients. The intravertebral instability was confirmed from the dynamic lateral view. The pain level was assessed both before and after the treatment using a visual analog scale. The kyphotic angle at last follow up was also checked.
RESULTS
In eight cases, intravertebral instability was shown at the clefts in flexion-extension radiographs. MRI showed that the cleft was low intensity on the T1- weighted image and high intensity on the T2-weighted image. The pre-and postoperative mean kyphotic angles were -18.3degrees and -8.5degrees respectively. The preoperative average pain score was nine and postoperative four. At last follow up the mean kyphotic angle was -16.6degrees CONCLUSION: The cleft with intravertebral vacuum phenomenon and magnetic resonance findings of low intensity on the T1-weighted scans and high intensity on the T2-weighted scans suggests that the cleft is a pseudarthrosis associated with avascular necrosis of the vertebral body. The posterior instrumentation and fusion provides satisfactory pain relief in patient with vertebral pseudarthsosis.

MRI Findings of Posterior Ligament Complex Injury in Thorcolumbar Bursting Fractures: Young Do Koh, Yeo Heon Yun, Hoon Jeong; J Korean Soc Fract 2003;16(4):541-547. Published online October 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.4.541

Abstract PDF: PURPOSE
To investigate the MR findings of structures injured in the burst fractures of thoracolumbar spine.
MATERIALS AND METHODS
Twenty-one patients who had thoracolumbar burst fractures with posterior ligament complex injury on MRI were studied. For the evaluation of stability of fractures, we used the scheme described by Oner et al. We identified the state of posterior ligament complex on surgery.
RESULTS
The MRI findings of ALL were state 1 in four, state 2 in fourteen, and state 3 in three. Those of PLL were state 1 in twelve, state 2 in six, and state 3 in three. The findings of posterior ligament complex were state 2 in one, state 3 in three, and state 4 in seventeen. The endplate state 1 was in four, state 2 in six, state 3 in seven, and state 4 in four. The disc state 1 was in twelve, state 2 in six, state 3 in two, state 4 in one. The vertebral body involvement state was 1 in four, state 2 in nine, and state 3 in eight. The injuries of posterior ligament complex were confirmed intraoperatively in all twenty-one patients.
CONCLUSION
We recommend the use of MRI to evaluate stability of fractures and state of posterior ligament complex in thoracolumbar burst fractures.

Loss of Fixation after Internal Fixation of Intertrochanteric Femoral Fracture with Compression Hip Screw: Jong Oh Kim, Sang Yeol Chang, Joon Gue Moon, Hoon Jeong, Woo Chul Jeong; J Korean Soc Fract 2003;16(3):334-339. Published online July 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.3.334

Abstract PDF: PURPOSE
To evaluate the factors which might affect the loss of fixation after surgical treatment of intertrochanteric fracture with compression hip screw.
MATERIALS AND METHODS
From February 1996 to February 2001, seventy nine cases of intertrochanteric fracture which we operated with compression hip screw was reviewed with minimal follow up for 6 months. There were twelve cases of loss of fixation. The cases were analyzed according to each factors which we thought to affect the loss of fixation. The factors are fracture type by modified Evans classification, Singh index, placement of screw in femoral head, quality of reduction. Then we analyzed these factors with chi square test.
RESULTS
Difference between age group and sex were not thought to be statistically meaningful factors (p>0.05). There were difference of prevalence between two group divided by fracture stability (p<0.05). In cases of superior placement in femoral head, there were more loss of fixation. Displacement of cortex of proximal femur on radiologic AP view other than lateral view showed meaningful difference (p<0.05).
CONCLUSION
Age, sex, Singh index did not affect the loss of fixation. But, next factors as follows affected the loss of fixation; Superior placement of hip screw, unstable fracture pattern, displacement of fracture site more than 5 mm after surgical reduction on radiologic AP view.
