Published online January 31, 2019; DOI: https://doi.org/10.12671/jkfs.2019.32.1.47

Abstract PDF: Shoulder joint dislocation has the most common incidence rate compare compared to other joints. It is reported that shoulder Shoulder dislocation couldmay be associated with glenoid rim, greater tuberosity of humerus and coracoid process fracture. There were have only been 2 cases of anterior shoulder dislocation simultaneously combined with simultaneous glenoid rim, coracoid process, and humerus greater tuberosity fracture worldwide and no report reports in Korea. We present a case of quadruple fracture (glenoid rim, coracoid process, greater tuberosity, surgical neck of humerus) associated with anterior shoulder dislocation and treated successfully by open reduction. In addition, with we provide the injury mechanism, diagnosis, treatment procedure and discussion.

Atypical Bipolar Segmental Fracture of the Clavicle in an Adolescent: A Case Report: Joong Bae Seo, Sung Hyun Yoon, Jun Kyom Kim, Sung Hyun Kim, Jae Sung Yoo; J Korean Fract Soc 2018;31(1):18-21. Published online January 31, 2018; DOI: https://doi.org/10.12671/jkfs.2018.31.1.18

Abstract PDF: Clavicular fractures commonly occur in adults and children. The usual site of these fractures is the mid clavicle with lateral end and medial end clavicular fractures being less common. Bipolar segmental clavicular injuries involving medial and lateral ends are rare but almost always occur in adults. This paper reports a very rare case of segmental clavicular fracture involving the medial and lateral end in an adolescent caused by direct trauma. The surgical management of a segmental fracture clavicle in an adolescent is reported with a discussion of the relevant literature.

Missed Fractures in Severely Injured Patients: Hee Gon Park, Jae Sung Yoo, Hyung Suk Yi; J Korean Fract Soc 2014;27(2):113-119. Published online April 30, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.2.113

Abstract PDF

PURPOSE
The purpose of this study is to analyze anatomic distributions, diagnostic methods, and prognosis of missed fractures in patients with severe injury.
MATERIALS AND METHODS
A review of single-institutional medical records between January 2001 and May 2012 identified 58 patients with 62 delayed diagnoses of fractures among 4,643 severely injured patients older than 20 years with Injury Severity Scores higher than 16. We evaluated combined injuries, location of fractures, diagnostic methods, and reasons for missed diagnosis at initial exam.
RESULTS
Among 62 missed fractures, there were eight cases of spine fracture, 10 cases of peri-shoulder joint fracture, eight cases of upper extremity fracture, 10 cases of pelvis of acetabulum fracture, and 26 cases of lower extremity fracture. Head injury was the most common concomitant injury (23 cases). Initially missed fractures were most commonly discovered by official reading by radiologists. The most common reasons for misdiagnosis were the use of improper radiologic study and missed-reading of proper radiologic studies.
CONCLUSION
In order to prevent misdiagnosis of fractures in patients with severe injury, meticulous physical examination with suspicion of fractures should come first. In addition, obtaining proper radiologic study and thorough evaluation of radiologic images are important to decreasing the rates of missed fracture diagnoses. In addition, thorough surveillance for ipsilateral fractures is important in extremities with identified fractures.

Clinical Outcomes of Locking Compression Plate Fixation through Minimally Invasive Percutaneous Plate Osteosynthesis in the Treatment of Distal Tibia Fracture: Jae Sung Yoo, Hyun Woo Park; J Korean Fract Soc 2012;25(2):117-122. Published online April 30, 2012; DOI: https://doi.org/10.12671/jkfs.2012.25.2.117

Abstract PDF

PURPOSE
To analyze the clinical results of operative treatment of distal tibia fracture with locking compression plate fixation through a minimally invasive percutaneous plate osteosynthesis technique.
MATERIALS AND METHODS
The subjects were 46 patients (conventional open surgery: 22 patients, minimally invasive percutaneous plate osteosynthesis: 24 patients) with fracture of the distal tibia who were treated with plating between November 2006 and June 2010. The time of bony union, complications, range of motion, and clinical functional outcome (according to American Orthopedic Foot and Ankle Society, AOFAS) were investigated.
RESULTS
In the minimally invasive percutaneous plate osteosynthesis group, the average union time was 14.3 weeks, postoperative range of motion was an average of 55.2, average AOFAS was 96.9, and incidence of complications was 20.8%. In the open surgery group, the average union time was 18.9 weeks, postoperative range of motion was an average of 49.1, average AOFAS was 83.8, and incidence of complications was 32.6%. There were statistically significant differences (p<0.05).
CONCLUSION
Surgical treatment with locking compression plate fixation through the minimally invasive percutaneous plate osteosynthesis technique showed favorable results regarding its union time, postoperative functional outcome, and incidence of complications. The locking compression plate fixation through minimally invasive percutaneous plate osteosynthesis technique can be an effective treatment option.

Clinical Outcome of Surgical Treatment for Fracture of the Femoral Shaft with Ipsilateral Fracture of the Proximal Femur: Hee Gon Park, Jae Sung Yoo; J Korean Fract Soc 2011;24(4):307-312. Published online October 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.4.307

Abstract PDF: PURPOSE
To analyze diagnostic process and clinical data in cases of fracture of the femoral shaft with fracture of the proximal femur.
MATERIALS AND METHODS
We reviewed 24 cases of patient who undergone surgery for fracture of the femoral shaft with ipsilateral fracture of the proximal femur and more than 1 year of examination of follow up was available. Age, sex.location and classification of the fracture, the time of diagnosis and operation, the method of operation, the associated injuries, the time of bony union and complication were investigated, postoperative function was evaluated on Friedman and Wyman criteria.
RESULTS
Bony union showed significant difference in the displacement and comminution of fracture, postoperative function revealed significant difference according to the associated injuries. The 6 cases (25%) out of 24 cases are failed early diagnosis, 4 cases out of 6 cases was detected during operation and 2cases was found after surgery. 21 cases out of 24 cases of femoral shaft fractures showed union, 23 cases out of 24 cases of femoral neck fractures showed union. There were eleven good, eleven fair, and two poor functional result according to Friedman and Wyman criteria.
CONCLUSION
Precious clinical and radiologic examination is needed not to miss the diagnosis of proximal femur fractures in ipsilateral femoral shaft fractures with proximal femur fractures. Anatomical reduction and rigid fixation of proximal femur are important to reduce avascular necrosis of femoral head and nonunion of proximal femoral fractures.

Operative Treatment of Distal Humeral Comminuted Fractures with Orthogonal Plating: Joong Bae Seo, Jae Sung Yoo; J Korean Fract Soc 2011;24(3):243-248. Published online July 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.3.243

Abstract PDF: PURPOSE
To analyze the results of operative treatment for Comminuted Fracture of Distal Humerus with Transolecranon approach and Orthogonal plating.
MATERIALS AND METHODS
The subjects were 22 patients with Comminuted fracture of humerus who were treated with Orthogonal plating. Patient's age, sex, type of fracture, surgical approach, method of fixation, time of operation, time of bony union, complication, range of motion were investigated, and Function of elbow was evaluated by functional evaluation of Riseborough and Radin, Mayo Elbow Performance Score (MEPS).
RESULTS
Age, sex, injuried arm, operation time were not related to postoperative result. Type C2 fractures showed better results in function and range of motion (ROM) than type C3 fractures. Also early rehabilitation was important to functional recovery and ROM. The postoperative ROM was average 110. Good were 16 cases, fair were 6 cases in functional evaluation of Riseborough and Radin. Excellent were 13 cases, good were 8 cases, fair was 1 case in MEPS.
CONCLUSION
Operative treatment with Transolecranon approach and Orthogonal plating showed favorable result on its function. Intraarticular comminution and early rehabilitation were closely related to postoperative function of elbow.
