Operative treatment of diaphyseal fractures of both forearm bones in adults: Eui Hwan Ahn, Sung Tae Lee, Ja Heon Koo; J Korean Soc Fract 2001;14(2):245-252. Published online April 30, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.2.245

PURPOSE
The purpose of this study is to evaluate the effectiveness of operative methods for diaphyseal fractures of both forearm bones in adults.
MATERIALS AND METHODS
Forty five cases with diaphyseal fractures of both forearm bones over 18 year old that are treated by operative methods from January 1994 to December 1998 were followed and analyzed. The most common age group was 3rd and 4th decade(each, 24.4%). Traffic accident was the most common cause of injuries(31.2%). Among both the radius and ulna, middle 1/3 was the most common level of fractures(60%, 57.8%). In operative methods, open redeuction and internal fixation with dynamic compression plate(D.C.P.) and screws were performed in 39 cases, closed reduction and internal fixation with Rush pin were performed in 5 cases, And another 1 case was performed with D.C.P. and Rush pin simultaneously.
RESULTS
According to simple X-ray and physical examinations, The average of bone union periods was 12.7 weeks in radius, 13.5 weeks in ulna. The range of bone union periods according to the level of fractures was from 12.4 weeks to 14.1 weeks. For the functional results assessed by Grace and Eversmann method, excellent was 48.9%, good was 35.6%, acceptable was 11.1% and unacceptable was 4.4%.
CONCLUSION
The functional result was satisfactory in 84.5%. So the operative method of diaphyseal fractures of both forearm bones, if proper operative method had been selected and meticulous surgical technique had been performed, was considered as recommendable method.

Posterior Dislocation of Elbow Joint with Fracture of Radial Head and Coronoid Process (Terrible triad of Elbow Fracture and Dislocation): case report: Eui Hwan Ahn, Sung Tae Lee, Hyun Sik Ahn; J Korean Soc Fract 2000;13(4):1011-1015. Published online October 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.4.1011

Abstract PDF: Dislocation of the elbow with fracture of the radial head and the coronoid process is a complex injury that includes severe damage to both soft tissue and bone. The above injury is named as 'terrible triad of elbow fracture and dislocation'. This injury is very rare and difficult to treat and this combined lesion has been reported to have a worse prognosis than either of the single injury. The complications of ectopic ossification, recurrent dislocation, and loss of motion are recognized as a source of considerable concern to the treating orthopaedic surgeon. Many authors emphasized the importance of fixation of coronoid process. The proper management of radial head fracture is controversial. Whatever method used, the elbow must be stable enough to permit early motion. We treated 2 patients who sustained posterior dislocation of elbow with fracture of radial head and coronoid process. First case was treated by closed reduction for dislocation of elbow immediately. After 2 days, radial head was excised and coronoid process was fixed with pulled-out technique. Second case was treated by closed reduction for dislocation of elbow immediately. After 3 days, radial head was treated with open reduction and internal fixation with K-wire and teared anular ligament was repaired. Clinical result of both cases was good

Treatment of comminuted Tibial Fractures using Ilizarov Method: Eui Hwan Ahn, Sung Tae Lee, Hyeon Seok Kang; J Korean Soc Fract 1999;12(4):916-923. Published online October 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.4.916

Abstract PDF: From March 1996 to March 1999, thirty two cases of comminuted tibial fractures were treated with Ilizarov external fixator. 13 cases were closed fractures and 19 cases open fractures. Among 19 open fractures, there were 3 cases of Gustilo type I, 10 cases of type II and 6 cases of type III fractures. All the cases could not be initially treated by open reduction and internal fixation because of open wound or severe comminution. Among 32 cases, 4 were tibial condyles, 22 were tibial shafts, 6 were tibial plafonds. All the cases were followed up from a minimum 12 months up to 35 months with an dverage of 22 months. We obtained satisfactory bony union in ail cases with the average duration of 18.1 weeks. Bone graft was done initially in two cases. Numerous complications were encountered, most commonly, joint stiffness and pin tract infection were developed but they were treated well. To avoid such complications, careful management was needed. According to Tuckers clafsification, the result was graded as excellent in 8, good in 18, fair in 4 and poor in 2 cases. We conclude that Ilizarov external fixatior is a very useful method for initial treatment in getting reduction, maintenance of reduction, early ambulation and fracture healing in cases of communited tibial fractures whether open or closed.

Management for Postoperative Infection of Fractures: Eui Hwan Ahn, In Whan Chung, Jeong Hwan Oh, Seong Tae Lee, Duk Hwan Kho; J Korean Soc Fract 1999;12(2):402-410. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.402

Abstract PDF

It is often difficult to eradicate infection and achieve bony union in postoperative infection after fracture fixation. Authors treated 14 such cases from February 1992 to February 1998, and followed up for 6 to 35 months. The purpose of this study is to review the clinical features of the postoperative infection and assess the treatment modality which influence the time required for attaining bony union and healing of infection. The results were as follows : 1. Primary fixation were left in place in 5 cases of stable fixation, and new external fixation and/or another fixations were required in 8 cases of unstable fixation. 2. Time required for achieving union was 4.7 months for stable primary fixation and 12.8 months for unstable primary fixation. 3. Time required for healing in infection was 3.5 months for stable primary fixation and 14.4 months for unstable primary fixation. 4. Bony union was delayed as the number of surgical procedures were increased. 5. Antibiotic cement beads were inserted for 5 cases into bony defect and dead space after curettage and sequestrectomy, and pus discharge was stopped after 8.8 weeks in average.

Treatment of Intertrochanteric Fractures of the Femur using Compression Hip Screw in the Senile Osteoporosis: Eui Hwan Ahn, In Whan Chung, Jeong Hwan Oh, Hyuck Jun Lee; J Korean Soc Fract 1998;11(1):168-174. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.168

Abstract PDF: The intertrochanteric fracture of the femur are seen in elderly patients who are highly vulnerable to generalized osteoporosis and various senile disease. Firm internal fixation and early ambulation is a goal of treatment. The morbidity and mortality after fracture remain high despite of the development of various devices. For this purpose, compression hip screw becomes popular recently. The purpose of this report is to assess the availability of compression hip screw in the intertrochanteric fracture in the senile osteoporosis by the review of 107 cases from Jan. 1990 to Jan. 1996. The result were as follows : 1. Eighty-three cases(77.6%) were unstable fractures. 2. The lag screw position in the femoral head of 76 cases(71%) were centerd 3. The average length of sliding of the lag screw was 9.9mm. 4. Satisfactory results were obtained in 91% of patients by the functional class of Clawson.

Remodelling and Reangulation following the Fracture of Both Bones of the Forearm in Children: Sung Tae Lee, Jeong Hwan Oh, Eui Hwan Ahn, Hyuck Jun Lee; J Korean Soc Fract 1997;10(4):972-978. Published online October 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.4.972

Abstract PDF: One-hundred fifty children underwent closed reduction for the fracture of both bones of the forearm were retrospectively reexamed with an average follow-up time of 28.7 months(range, 13-60 months). Patients were divided into three groups of 50-complete fractures, 50-green-stick fractures broken intact cortex and 50-green-stick fractures preserved intact cortex. The rate of the reangulation after closed reduction was lowest on the green-stick fractures preserved intact cortex. Forty-seven patients with residual angulation after healing were divided into two age groups of 4-10 years and 10- 15 years at the time of fracture. In children younger than 10 years of age with residual angulation after distal fractures of both bones of the forearm, the change of orientation of the epiphyseal plate toward the normal seemed to account for nearly all the actual correction at the site of fracture. The hinge should be used to aid in an accurate and stable reduction. The importance of the orientation of the epiphyseal plate is related to the distance between the fracture site and the epiphyseal plate according to the age of the patient.
