PURPOSE
The purpose of this study is to compare the Phemister technique with the modified Phemister technique for the patients with Rockwood type 3, acromio-clavicular separation.
MATERIALS AND METHODS
The 45 cases of 45 patients received surgical treatment for Rockwood type 3, acute acromio-clavicular separation in our hospital from Feb. 1992 to Aug. 2001 later with the follow-up study were selected as subjects. The average ages were 28.1 years old, male and female were 42, 3 persons, respectively. Physical examination and plain radiography were used for their diagnosis and the intervals between injury and surgical treatment were 7.8 days. In intraoperative finding, we performed Phemister technique in 15 cases according not to be able to repair coraco-clavicular ligament (group I), modified Phemister technique in 30 cases according to be able to repair that (group II). The average follow up period was 16.2 months, and the UCLA shoulder scoring system and the acromio-clavicular separation scoring system were used to obtain clinical results.
RESULTS
Only in Group II, the complication after surgery were associated with superficial infection in two cases and K-wire migration in one case. At last follow up, there were no pain and limitation of range of motion in all cases, and two cases in Group II were found to be subluxation in radiography. Clinical results revealed excellent was 93.3%, good was 6.7% in UCLA shoulder scoring system in both groups, and excellent was 90%, good was 10% for group II in acromio-clavicular separation scoring system.
CONCLUSION
The results are considered to be good with only Phemister technique in type 3, acute injury occurred in working ages.

Stress Fracture of the Femoral shaft
Sung Ho Hahn, Bo Kyu Yang, Seung Rim Yi, Shun Wook Chung, Hyoung Sik Kim
J Korean Soc Fract 2001;14(2):200-207.   Published online April 30, 2001
DOI: https://doi.org/10.12671/jksf.2001.14.2.200
AbstractAbstract PDF
PURPOSE
This study was evaluated to find the aspect of the femoral shaft stress fracture. MATERIAL AND METHOD: From Jan. 1990 to May. 1999, this study included 8 cases diagnosed as stress fracture of the femoral shaft that were proved by clinical & radiologic findings in our hospital. Patients with undisplaced femoral shaft stress fracture were treated conservatively and patients with displaced ones were treated with open reduction and internal fixation.
RESULT
5 of 8 fractures were located in the distal shaft and 3 were in the middle shaft. 5 of 8 fractures were undisplaced and 3 were displaced. These 3 displaced fractures were located in the distal shaft.
CONCLUSION
According to our experience, femoral distal shaft stress fracture which is rare, has a high tendency to displace. Therefore, the early diagnosis and prevention of femoral distal shaft fracture is important to prevent progression to displaced fracture.

MRI Findings of Stress Fracture in Long Bone
Sung Ho Hahn, Bo Kyu Yang, Seung Rim Yi, Shun Wook Chung, Yang Hee Park, Dong Oh Ko
J Korean Soc Fract 2001;14(2):145-151.   Published online April 30, 2001
DOI: https://doi.org/10.12671/jksf.2001.14.2.145
AbstractAbstract PDF
PURPOSE
The goal of our study was to evaluate diagnosis and management of stress fracture in long bones using MRI findings. MATERIAL & METHOD: Between May 1995 to May 1999, 40 patients( 45 cases ) were confirmed to have a stress fracture by clinical and radiological findings. All patients were evaluated with clinical, X-ray, bone scan, and MRI findings. The patient was 21 years in average( range from 18 to 23 years ). All were males and soldiers. The evaluation was made by comparison of MRI and plain radiograph, and duration of symptom was evaluated with MRI grading by Fredericson et al.
RESULT
The locations of stress fracture of long bones were tibia(n=25), fibula(n=14), and femur(n=6). MRI findings were bone marrow edema in 38(84.4%)cases, intramedullary low signal intensity band in 19(42.2%)cases which was continuous with cortex and cortical fracture line. Periosteal reaction was seen in 45(100%)cases and surrounding soft tissue edema in 20(44.4%)cases. Plain X-ray findings were peristeal reaction in 31( 68.9%)cases, medullary sclerosis in 10(22.2%)cases, and cortical fracture line in 8(17.8%) cases. Duration of symptom was longer in higher MRI grade.
CONCLUSION
MRI was more useful in early diagnosis and differential diagnosis of stress fracture, showing various findings than plain radiograph. MRI grading was helpful in planning tlhe therapy of stress fracture.

Treatment of the Distal Femoral Fracture with Anatomical Bone Plate
Sung Ho Hahn, Bo Kyu Yang, Seung Rim Yi, Shun Wook Chung, Je Oh Lee
J Korean Soc Fract 2000;13(2):258-266.   Published online April 30, 2000
DOI: https://doi.org/10.12671/jksf.2000.13.2.258
AbstractAbstract PDF
PURPOSE
: In this paper, we have intended to evaluate the types of fracture of the distal femur treated with anatomical bone plate, simple and user's friendly apparatus and to assess their clinical results.
MATERIALS AND METHODS
: We retrospectively reviewed 21 cases in 20 patients who were followed up over 1 year among the patients that had distal femoral fractures treated with anantomical bone plate. We analysed their fracture types in AO classification and assessed clinical results according to Neer system. The average duration of follow-up was 30 months(range, 14months to 49 months).
RESULTS
: Ont of twenty-one cases, twelve were A type(A1, 3 cases;A2, 4cases;A3, 5 cases)and nine were C type(C1, cases;C2, 4cases; C3, 3 cases). But B type was none.
CONCLUSIONS
: This study demonstrate that the operation with anatomical bone plate is not only simple and user's friendly technique but also widely appleicable method to treat A and C types of the distal femoral fractures.
