BACKGROUND: We investigated the effectiveness of fibular strut allograft augmentation of proximal humerus fractures to prevent varus deformity in patients over the age of 65 years with insufficient medial support. METHODS: We analyzed the clinical and radiological outcomes of locking plate fixation with adjunct fibular strut allograft augmentation in 21 patients with proximal humeral fractures. The inclusion criteria were age (65-year-old or older); presence of severe medial comminution; inadequate medial support; and those who could participate in at least a one year follow-up. The average age was 76.4 years. We analyzed each patient's Constant score, our indicator of clinical outcome. As radiological parameters, we analyzed time-to-bone union; restoration of the medial hinge; difference between the immediately postoperative and the last follow-up humeral neck-shaft angles;; and anatomical reduction status, which was assessed using the Paavolainen method. RESULTS: A successful bone union was achieved in all patients at an average of 11.4 weeks. We found that the average Constant score was 74.2, showing a satisfactory outcome. The average difference in the humeral neck-shaft angles between the immediately postoperative time-point and at the final follow-up was 3.09°. According to the Paavolainen method, the anatomical reduction was rated excellent. The medial hinge was restored in 14 of 21 patients. Although we did not find evidence for osteonecrosis, we found that a single patient had a postoperative complication of screw cut-out. CONCLUSIONS: Fibular strut allografting as an adjunct treatment of proximal humeral fractures may reduce varus deformity in patients with severe medial comminution.

One case of osteoid osteoma in the lamina of the fifth lumbar spine with hamstring muscle tightness was experienced and successfully treated by surgery at the department of orthopedic surgery in Seoul National University Hospital. Literature on the subject was reviewed in detail.

Marfan Syndrome is a rare congenital disease characterized by the abnormalities of Sheletal system, eye and cardio-vascular system which was initially desiribed by Marfan in 1896. One case of marfan syndrome was treated at the department of Orthopedic Surgery, College of Medicine, Seoul National University for multiple skeletal deformities. Moderate degree of scoliosis was treated with Milwaukee brace and finger deformities with Z-plasty and full thickness skin graft.

Two hundreds cases of spine tuberculosis were treated surgically for the period of 7 years between 1970 and 1976 at Seoul National University Hospital and following results were obtained. 1. Many patients failed to be treated with conservative method. Spontaneous fusion was found in 10% of 200 cases with long duration of disease. Anterior fusion was performed in 166 cases and posterior fusion was carried out in 34 cases. In those 34 cases, anterior currettage was combined in 7 cases, anterior fusion combined in 19 cases in which 7 cases were performed anterior and posterior fusion at one stage. Posterior fusion alone was carried out only in 8 cases. 2. Anterior fusion is indicated for: a. decompression in cord involvement b. confirmation of diagnosis c. involvement of one joint space in children d. mild to moderate kyphosis in adult 3. Anterior and posterior fusion is indicated in: a. severe kyphosis for solid funsion b. involvement of more than two joint spaces in children to prevent increasing kyphosis c. one stage operation was technically possible and has many advantages 4. Posterior fusion is indicated in: a. poor general condition b. technically difficult cases.

PURPOSE: Retrospectively, the purpose of this study is to investigate the necessity for early operation for patients with rotator cuff tears and concomitant adhesive capsulitis. METHODS: From March 2013 to March 2017, we conducted a retrospective study on patients with rotator cuff tears and concomitant adhesive capsulitis. We analyzed 32 cases out of 39 cases who have small to medium rotator cuff tears, excluding patients who were unable to follow up over 1 years. We evaluated range of motion, visual analog scale (VAS) score, and Constant score. We compared patients of non-symptom and symptomatic patients related to rotator cuff tear. RESULTS: Among patients in the 32 cases, 21 cases of total patients improved without discomfort after recovering their range of motion and pain (group 1), and 11 cases were developed symptoms related to rotator cuff tear for the last 1 year (group 2). Average age of group 1 patients was 53.4 years old, and recovered from forward elevation 95.5° to 163.2°, external rotation from 8.5° to 68.7°, mean VAS score improved from 6.2 to 1.2. Average age of group 2 patients was 58.4 years old, and recovered from forward elevation 96.2° to 162.2°, external rotation from 8.1° to 67.8°, mean pain VAS score improved from 6.4 to 4.4. But there was statistically significant difference in pain reduction after restoration of motion compared to asymptomatic group. CONCLUSION: We do not need surgical treatment at the same time because the symptoms of rotator cuff tear may not be manifested in patients with rotator cuff tear associated with adhesive capsulitis. Sufficient follow-up should be considered after restoration of shoulder motion related to adhesive capsulitis.

Supracondylar fracture of the femur is not as common as the shaft fracture. There is wide range of potential complication in the treatment of these fractures and the method of the treament and the evaluation of it's result is variable and remains controversial. Until 1960, we believed conservative treatment supirior to the operative treatment of the supracondylar fracture of the femur. But recently, anatomical reduction and internal fixation with early joint motion showed satisfactory results and is the trend of treatment of these fracture. The authors of this thesis performed treatment of supracondylar fracture of femur by utilizing Ender nails and screws in 13 cases during the period from October 1987 to November 1988 and it was found that operation was relatively simple, bleeding was little and early exercise of knee was allowed and even for patients of old age internal fixation could be maintained easily.

Transplantation of the scleral homograft was performed with 6 rabbits in order to evaluate its usefulness as a material for frontalis sling operation. Scleral homografts which were surrounded by connective tissue maintained normal scleral architecture until the 12th week of subcutaneous implantation. Under the electronmicroscopic examination, sclenl homografts maintained their proper collagen fiber type I architecture until the 12th week. With these results we considered that homologous scleral shell could be a promising material for frontalis sling operation.

PURPOSE: This study analyzed the results of the midclavicle fracture treatment using the minimally invasive percutaneous plate osteosynthesis (MIPO) technique in a retrospective manner. MATERIALS AND METHODS: Between March 2013 and March 2017, this study analyzed 40 patients who received MIPO surgery. Excluding 1 patient who underwent surgery on another body part injury, and 4 patients who were lost to follow-up over 1 year, 40 patients were analyzed for their operation time, bone union, functional American Shoulder and Elbow Surgeons score, scar lengths, pain relief (visual analogue scale), and complications. RESULTS: All patients over a 1 year of follow-up achieved bone union, and American Shoulder and Elbow Surgeons score 97.6 (94–100) on their shoulder functional scores. Their average operation time was 42.7 minutes, and the average scar length was 6.1 cm. Eighteen patients successfully received metal removal using the previous scar without additional incision. The clavicle length was similar in the normal and operated group. CONCLUSION: Despite its small sample size, clavicle fixation using the MIPO technique can be considered an effective treatment because of its limited number of complications, such as nonunion and rotational angulations.
