Malunion of the Odontoid Process Developing Cervical Myelopathy: A Case Report: Teak Soo Jeon, Sang Bum Kim, Whan Yong Chung, Woo Sik Kim, Sung Hun Kim, Tae Kyun Kim; J Korean Fract Soc 2006;19(3):378-380. Published online July 31, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.3.378

Late-onset progressive myelopathy, years after odontoid fracture, is considered a rarity. Undiagnosed or untreated odontoid fractures may develop into nonunion or malunion, thereby leading to secondary delayed cervical myelopathy. We present a case of a 50-year-old man with malunion of odontoid fracture. We had a good result following one-staged posterior decompression and occipito-cervical fusion.

Distal Radioulnar Joint Injuries Associated with Intra-articular Fracture of Distal Radius: Woo Sik Kim, Yong Sang Kim, Whan Yong Chung, Woo Suk Lee, Taek Soo Jeon, Seung Ryul Ryu; J Korean Fract Soc 2006;19(2):221-227. Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.221

Abstract

PURPOSE
To evaluate the significance of distal radioulnar joint injury which may affect the postoperative radiologic and clinical results of AO classification, type C distal radius fractures.
MATERIALS AND METHODS
From October 2000 to October 2005, 58 patients of AO classification, type C distal radius fracture, who had been treated with operative methods were studied. They are thirty-six men and twenty-two women. The average follow up period was 14 months. The patients were divided into five groups. In the first group (13 cases), there was no distal radioulnar joint injuries. In the second group (20 cases), there were ulnar styloid fractures. In the third group (11 cases), there were separation of distal radioulnar joint. In the fourth group (9 cases), there were ulnar styloid fractures with separation of distal radioulnar joint. In the fifth group (5 cases), there were displacement of ulna in sagittal plane. We measured the radial length, radial inclination and volar tilt in plain radiograph in each group and analyzed the results through Scheck's methods. To analyzed the clinical results, we used the Demerit Point System by Sarmiento.
RESULTS
There was no significant differences in radiologic and clinical results among the five groups.
CONCLUSION
According to compairing the radiologic results of each group which was suspicious of distal radioulnar joint injuries, in the intraarticular comminuted fractures of distal radius, the distal radioulnar joint injuries did not affect the results of treatment when anatomical reduction of distal radius was achieved.

Instability of Knee Associated with Ipsilateral Femoral and Tibial Shaft Fractures: Whan Yong Chung, Woo Suk Lee, Woo Sik Kim, Yong Chan Kim, Taek Soo Jeon, Sun Hong Kim, Ji Hyuk Lim, Young Su Lim; J Korean Fract Soc 2005;18(2):136-143. Published online April 30, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.2.136

Abstract PDF: PURPOSE
To establish the incidence, type and significance of knee instability in patients with ipsilateral femoral and tibial shaft fracture, comparing with the patients with femoral shaft or tibial shaft fracture alone.
MATERIALS AND METHODS
Two hundreds and seventy-nine consecutive patients were retrospectively reviewed from February 2000 to April 2004. They were composed of 80 patients with femoral shaft fracture alone, 176 patients with tibial shaft fracture alone and 23 patient with ipsilateral femoral and tibial shaft fracture. We evaluate the instability of knee based on physical examinations, plain stress films and MRI. We analyze incidence and period to diagnosis of instability, period to complete bony union and Hospital for Special Surgery (HSS) knee score respectively.
RESULTS
There were 6.3% of knee instability in femoral shaft fracture alone, 9.7% in tibial shaft fracture alone and 30.4% in ipsilateral femoral and tibial shaft fracture. The average period to diagnosis of instability, average period to complete bony union and average HSS knee score were 9.2 months, 4.7 months and 65 points in femoral shaft fracture alone, 9.1 months, 4.2 months and 69 points in tibial shaft fracture alone, 8.7 months, 5.3 months (femur), 4.7 months (tibia) and 57 points in ipsilateral femoral and tibial shaft fracture respectively.
CONCLUSION
We should consider MRI to evaluate the knee instability in patient with ipsilateral femoral and tibial shaft fracture at the time of injury and make a plan early about the treatment of knee instability.

Intercondylar Fracture of Distal Humerus in Children: Woo Suk Lee, Whan Yong Chung, Woo Sik Kim, Yong Chan Kim, Taek Soo Jeon, Nam Hyun Kim, Kyoo Tae Kim; J Korean Fract Soc 2004;17(4):380-383. Published online October 31, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.4.380

Abstract PDF

Intercondylar fractures of the distal humerus are very rare in children. The pattern of the fracture would suggest that the mechanism of injury involves a fall directly on the flexed elbow. Most agree that the undisplaced fracture can be managed conservatively. With increasing displacement and comminution, the opinions tend to differ. We suggest that closed reduction with percutaneous K wire pinning and open reduction with percutaneous K wire pinning offer a satisfactory methods by which to treat displaced intercondylar fracture in children.

Anterolateral Approach for the Distal Metaphyseal Fracture of the Tibia: Taek Soo Jeon, Jae Woo Lim, Whan Yong Chung, Woo Suk Lee, Woo Sik Kim, Cheol Mog Hwang, Yong Chan Kim, Nam Hyun Kim, Yong Sang Kim, Sung Kwan Jo; J Korean Fract Soc 2004;17(3):243-248. Published online July 31, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.3.243

Abstract PDF: PURPOSE
The purpose of this study is to evaluate the effectiveness of anterolateral approach of the ankle for the distal tibial fracture in aspect of preventing complication and acquiring union.
MATERIALS AND METHODS
Authors reviewed 21 patients of distal metaphyseal fracture of the tibia treated by anterolateral approach and lateral plating method from February, 2000 to May, 2002. Mean follow-up period was 17 months (12~29 months). There were twelve type A, two type B, and four type C patients according to AO/OTA classification. We have analyzed the bone union rate and Ovadia`s functional scale. We also reviewed the complication rate, such as soft tissue problem and postoperative infection.
RESULTS
In all cases union was achieved and mean time to union were 16 weeks. The functional result by Ovadia's scale were 17 excellent cases and 4 good cases in objective evaluation, and 19 excellent cases and 2 good cases in subjective evaluation. Wound infection occurred in one case, but the infection was controlled after plate removal and the union was acquired through cast immobilization. There was no other complication, such as soft tissue necrosis.
CONCLUSION
The anterolateral approach is a safe and worthwhile method for distal tibia fracture while avoiding some of the complication associated with standard anteromedial approach and plating method.

Postoperative Evaluation of Displaced Intra-articular Calcaneal Fractures by Computed Tomography: Woo Sik Kim, Kwang Kyoon Kim, Whan Yong Chung, Woo Suk Lee, Yong Chan Kim, Taek Soo Jeon, Dae Hwan Kim, Seong Jin Cho, Chul Mok Hwang; J Korean Fract Soc 2004;17(3):249-256. Published online July 31, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.3.249

Abstract PDF

PURPOSE
The purpose of the present study was to define the factors that affect the treatment and clinical result of displaced calcaneal fracture with use of the pre- operative and final follow-up computed tomography scanning.
MATERIALS AND METHODS
Present study included the 17 patients(18 feet) whom we performed surgery for displaced intra-articular calcaneal fracture at our institution between March 2000 and March 2002 and had a minimum follow-up of 12 months. For all patients, the Bohler's angle and posterior facet incongruity were measured with computed tomography pre- and post-operatively. The Creighton-Nebraska Health Foundation Assessment Scale for Fractures of the Calcaneus (CN scale) was used to evaluate the clinical results.
RESULTS
Of all eighteen fractures, the clinical results were excellent in three (16.6%), good in six (33.3%), fair in six (33.3%), and poor in three (16.6%). The Bohler's angle averaged 21degrees, 15degrees, 27degrees, 25degrees at final follow-up in each above clinical result group. The step-off averaged 1.0, 1.6, 3.9 and 6.0 mm and the average range of motion of the subtalar joint at final follow-up were 85, 76, 60 and 45% of normal. CT evaluation showed intra-articular screws in the posterior subtalar joint in three (16.6%) of the eighteen fractures but their average clinical result was good (80.3 points).
CONCLUSION
The restoration of the congruity and range of motion of posterior subtalar joint are considered important factor that affect clinical result.

Delayed Brachial Plexus Palsy due to Clavicular Fracture: A Case Report: Woo Suk Lee, Whan Yong Chung, Taek Soo Jeon, Yong Sang Kim, Nam Hyun Kim; J Korean Soc Fract 2003;16(2):230-234. Published online April 30, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.2.230

Abstract PDF

The brachial plexus palsies secondary to nonunion of the clavicle fracture are extremely rare. The nonunions are hypertrophic and usually in the middle third of the clavicle. Hypertrophic callus produced during healing process will cause a compression of the neurovascular bundle. This lesion requires operative treatment for decompression of the brachial plexus and internal fixation of nonunion. We present a case of delayed brachial plexus palsy due to nonunion and excessive callus formation of a clavicular fracture.

Abstract PDF

PURPOSE
This is a retrospective study to analyze the clinical results of the usefulness of K-wires and tension band wiring that fix the fracture fragment directly without passing the acromioclavicular joint in distal clacivle type II fractures.
MATERIALS AND METHODS
From May 2000 to May 2001, eleven patients with distal clavicle type II fracture were treated by open reduction and internal fixation with K-wires and tension band wiring. The clinical results were analyzed according to modified shoulder rating scale for distal clavicle freacture. Radiological union, complication, and range of motion of the shoulder were assessed.
RESULTS
All fractures were united at 10 weeks (8~12 weeks) in average. Finally, full range of motion of the shoulder joint was achieved in all patients. No complication was found and the modified shoulder rating scale for distal clavicle fracture were as follows: excellent 9 and good 2.
CONCLUSION
K-wires and tension band wiring can be a good treatment method for distal clavicle type II fractures.

Abstract PDF: PURPOSE
This is a retrospective study to analyze the clinical results of the usefulness of the lateral J plate fixations in distal humeral shaft and metaphyseal fractures.
MATERIALS AND METHODS
From October 1996 to May 2000, eleven patients with distal humeral shaft and metaphyseal fracture were treated by open reduction and internal fixations with lateral J plate fixations. The clinical results were analyzed according to Morrey 's functional rating scale. Radiological unions, complication, and range of motion of the elbow were assessed.
RESULTS
All fractures were united at 12 weeks (range, 10 ~18) in average. Finally, average range of motion of the elbow joint was flexion contracture 6 degrees in average(range, 0 ~20) to further flexion 126 degrees in average (range, 90 ~1 5 0 ) . Morrey 's functional rating scale were as follows; excellent 4, good 6, and fair 1.
CONCLUSION
Lateral J plate fixations can be a good treatment method for the transitional zone of distal humeral shaft and metaphyseal fractures.
