Growth Expectation in Children: Leg Length Discrepancy Related with Bone Tumor in Children / 대한골관절종양학회지

The main goals of treatment of malignant bone tumor are the prolongation of life survival and the improvement of quality of life. In growing children, however, leg length discrepancy (LLD) is one of major problem in the treatment of malignant bone tumors. Therefore, the precise understanding of growth in children is essential, and the prediction of LLD is critical in deciding the time and options of surgery. In addition, to use the adequate method of growth expectation, periodic follow-up and collaboration with patient's parents are needed.

The Alignment and Deformity of the Upper Extremity in Hereditary Multiple Exostoses / 대한골관절종양학회지

PURPOSE: This study was aimed to analyze the incidence and the anatomical distributions of HME (Hereditary Multiple Exostoses) on upper limbs and its related change in alignment of the upper limbs in HME patients. MATERIALS AND METHODS: Thirty eight patients who had been diagnosed HME between 2001 and 2009, were categorized into two groups; (1) group A (1-2 involvements); (2) group B (> or =3 involvements). We checked the carrying angle, VAS (Visual Analogue Scale), limitations in daily activities, cosmetic satisfaction according to the number of exostoses invasion. RESULTS: Among the 38 patients, 23 patients (43 cases) had exostoses in the upper limbs. The locations of exostoses in the upper limbs were proximal humerus in 33 cases (30%), distal ulna in 31 cases (28.2%), and distal radius in 24 cases (21.8%). The carrying angle of group A and B was 10.7degrees, 13.8degrees, VAS was 1.3, 3.5, and the limitations in daily activities was 7.3, 6.6 of 8 points. The cosmetic satisfactory cases were 13 and 10 cases, respectively. CONCLUSION: The deformity in upper limbs was observed in 65% of the HME patients. As the number of invasion increases, carrying angle and VAS were increased but limitations in daily activities and cosmetic satisfaction were decreased.

Double Primary Presentation of Liposarcoma and Ewing's Sarcoma: A Case Report / 대한골관절종양학회지

The development of different entities of soft tissue sarcoma in one patient is rare. It usually affects head and neck or abdominal region, whereas those affecting the extremities are much rarer. We describe a patient with double primary presentation of liposarcoma and Ewing's sarcoma in extremity. This case implies that sarcoma patients are at increased risk of a second malignancy, and this implies a need to search for occult tumors during follow up.

Hip Joint Surgery without Transfusion in Patients Who Were Jehovah's Witnesses: A Report of Two Cases

Jehovah's Witnesses are widely known for their prohibition for accepting blood transfusion. Because of the firm refusal to receive transfused blood and blood components by Jehovah's Witnesses, the management of Jehovah's Witness patients with severe bleeding is often complicated by medical, ethical and legal concerns. We report here on two cases of successful treatment of Jehovah's Witnesses who underwent total hip replacement for secondary osteoarthritis and Chiari osteotomy for acetabular dysplasia.

Plate Fixation of AO Type C3 Fractures of the Distal Radius

PURPOSE: To evaluate clinical and radiographic results of open reduction and internal fixation with plate in AO type C3 distal radius fracture. MATERIALS AND METHODS: We treated 18 fractures and the mean follow up was 16 months. The average age was 47.1 years old, 12 male and 6 female were included. There were 9 C3.1 fracture, 5 C3.2 and 4 C3.3. Green & O'Brien's modified clinical scoring system and Demerit Point system were applied to evaluate clinical results, for radiographic evaluation, radial length, radial inclination, volar tilt, and Sarmiento's Criteria for Anatomic results were assessed. RESULTS: Clinical results were 5 of excellent, 7 of good, and 6 of fair by Green & O'Brien's score and were 5 of excellent, 6 of good, and 7 of fair by Demerit point. There was no significant difference of radiographic results between immediate postoperation and last follow-up, and Sarmiento's Criteria showed 8 excellent, 4 good, and 6 fair. CONCLUSION: The open reduction and internal fixation with plate in AO type C3 distal radius is considered as a good treatment method that particularly benefits from fracture stable fixation without fixation loss and early rehabilitation.
