This study was performed to assess the growth plate closure time with aging in the Korean native goat. Radiographs of proximal and distal epiphysis of humerus, radius, ulna, femur and tibia were obtained at 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 17, 18, 20, 21, 30, 43 and 52 weeks after birth in 30 Korean native goats. The secondary ossification centers were scrutinized and assessed the maturity process on the basis of the criteria(stage 0 to 10). The secondary ossification centers of proximal and distal epiphysis of humerus, radius, femur and tibia and proximal ulna epiphysis appeared immediately after birth. While, that of distal ulna epiphysis appeared during the 1st to 2nd week of life. The fusion of distal humeral epiphysis occurred during the period from 8 to 12 months. The fusion of proximal radial epiphysis and distal tibial epiphysis were found at 1 year. The fusion of proximal and distal epiphysis of ulna and femur, proximal epiphysis of humerus and tibia and distal epiphysis of radius were found at 1 year or more than 1 year. As a result, growth plate closure was highly related to age in the Korean native goat and it is suggested that the estimation of animal's age might be useful by illustration of maturity process of the secondary ossification centers in the Korean native goat.

Brown tumor is tumor like lesion resulted from hyperparathyroidism, and it has been rarely reported recently. We evaluated a 29-year-old woman who had brown tumor on proximal humerus caused by primary hyperparathyroidism. She first had presented pain and swelling over the upper arm, and was suspected as giant cell tumor in biopsy combined with hyperparathyroidism. Wide marginal excision and tumor prosthesis were performed. However, it was confirmed as brown tumor resulted from parathyroid adenoma according to laboratory findings and radioactive isotopes image, and surgical excision of adenoma relieved clinical symptoms. We report this case with a review of literatures.

Shoulder bone scan everyday life, sports activities at the side of the shoulder joint, or applying strong force in the lateral occurs. Mainly on upper arm abduction, temple, other rotational dislocation of the shoulder joint gahaejyeo as useful for observing the presence or absence of lesions is used. Shoulder PA oblique projection prevent distortion of the image due to the angle and the most useful diagnostic radiological investigate shooting angle. Shoulder blade body and the acromion and coracoid process Y-view is formed characters. $10^{\circ}$ angle between the shoulder blades and the acromion is the obstruction. $20^{\circ}{\sim}25^{\circ}$ to the Y-view of the humerus head looks superimposed, the position of the shoulder joint and seemed appropriate. $35^{\circ}$ of the humerus head superimposed on the Y-view, but above the humerus head and shoulder joints were distorted. When $45^{\circ}$ elevation observed on the side of the best has come Y-view also acromion and coracoid process is finished.

Background: The execution of fibular allograft augmentation in unstable proximal humerus fractures (PHFs) was technically demanding. In this study, the authors evaluated the clinical and radiographic outcomes after tricortical iliac allograft (TIA) augmentation in PHFs. Methods: We retrospectively assessed 38 PHF patients treated with locking-plate fixation and TIA augmentation. Insertion of a TIA was indicated when an unstable PHF showed a large cavitary defect and poor medial column support after open reduction, regardless of the presence of medial cortical comminution in preoperative images. Radiographic imaging parameters (humeral head height, HHH; humeral neck-shaft angle, HNSA; head mediolateral offset, HMLO; and status of the union), Constant score, and range of motion were evaluated. Patients were grouped according to whether the medial column support after open reduction was poor or not (groups A and B, respectively); clinical outcomes were compared for all parameters. Results: All fractures healed radiologically (average duration to complete union, 5.8 months). At final evaluation, the average Constant score was 73 points and the mean active forward flexion was $148^{\circ}$. Based on the Paavolainen assessment method, 33 patients had good results and 5 patients showed fair results. The mean loss of reduction was 1.32 mm in HHH and 5.02% in HMLO. None of the parameters evaluated showed a statistically significant difference between the two groups (poor and not poor medial column support). Conclusions: In unstable PHFs, TIA augmentation can provide good clinical and radiological results when there are poor medial column support and a large cavitary defect after open reduction.

Purpose : The purpose of the current study is to evaluate the functional and oncologic results of the limb salvage surgery with intramedullary nailing and cementization in malignant bone tumors of the proximal humerus. Materials and Methods : We reviewed 18 cases of limb salvage surgery of resection and reconstruction with an intramedullary nail and cement-molded humeral head for the malignant bone tumors of the proximal humerus, which performed between August, 1992 through the April, 1998. The diagnoses included the osteosarcoma in 7 patients, chondrosarcoma in 3, the recurrent giant cell tumor in 3, metastatic tumor in 3, multiple myeloma in one patient and the one patient with malignant fibrous histiocytoma. The mean age at the time of surgery was 38 years(range, 15-73 years). The mean follow-up period was 26 months(range, 6-67 months). Results : Average functional score by ISOLS evaluation system was 21.1(70.3%). There were 3 local recurrences and 5 distant metastases. There were one case of shoulder instability and one case of deep infection. The seven patients are continuously disease free state and seven patients are alive with disease. Four patients died from the disease. Conclusion : The limb salvage surgery with intramedullary nailing and cementization in the bone tumors of the proximal humerus may be considered an option for the malignant bone tumors of the proximal humerus in selected patients.

The anatomical structure of the Skeleton of thoracic limb of thirty-one adult Korean native goats(body weight: 14~17kg) was observed after skeletal preparation, and the osteometry was performed in each bone. The results were as follows; 1. The thoracic limb of the Korean native goat was composed of scapula, humerus, radius, ulna, carpal bones, metacarpal bones, phalanges and sesamoid bones. 2. The scapula was flat and triangular in shape. There were no distinct tuber of spine and acromion in the spine. The subscapular fossa was deep and triangular in shape and the vertebral border was sigmoid form. The coracoid bone was formed as the coracoid process at the medial aspect of the supraglenoid tubercle but the clavicle wa.s not observed. The left and right scapular indexes were 57.92 and 58.31 and the glenoid cavity indexes were 89.23 and 86.82, respectively. 3. The greater tubercle of the humerus was devided into cranial and caudal parts. The third tubercle was observed and the face for the infraspinatus muscle was rectangular form. The left and right humerus indexes were 32.44 and 32.63, the head indexes were 94.13, 96.62 and the trochlear-epidondyle indexes were 67.32 and 65.81, respectively. 4. The radius and ulna were fused entirely except at the broad proximal and narrow distal interosseous spaces. The ulna was longer than the radius, and its reduced body and distal end were fused at the caudomedial surface of the radius. 5. The carpal bones were six in number. There were radial, intermediate, ulnar, accessory, second-third and fourth carpal hones in carpal bones. 6. The metacarpal bone was composed of a large metacarpal bone resulted from the fusion of the third and fourth metacarpal bones, and there was a metacarpal tubercle at the dorsolateral part of the proximal end. There were no vestiges of the second and fifth metacarpal bones. 7. The digits were composed of third and fourth digits and each digit was composed of the proximal, middle and distal phalanges. 8. The sesamoid bones were six in number. There were two at the fetlock joint and one at the coffine joint palmarly in each digit. 9. The ratios of the lengths among the scapula, humerus, antebrachium and metacarpal bone were 1.42 : 1.47 : 1.77 : 1.00 in the left and 1.42 : 1.45 : 1.77 : 1.00 in the right, respectively.

Consideration of Glenohumeral joint's image with the Changed Body angle of the Glenohumeral joint's Oblique Position in Erect Position. Glenohumeral joint's of Grashey method is a shoulder oblique method available to view the shoulder joint. Grashey method projects AP view of the Glenohumeral joint's so that the Humerus head's subluxation or joint degeneration can be easily visualized. However in this view, the patients, erect position, have to keep their body obliquely. Oblique position is will be needed to get the good quality Glenohumeral joint's view. Therefore, we thought of examining a method which shows the Glenohumeral joint's well by angling the patient one side upward in erect position. For this study, total 20 subject with no history of neurological or psychiatric illness, were recruited for examinations. They consisted of 13 mails and 7 femails, Statistic group analysis was performed with ANOVA test. Score of the evaluation of the expects were $30^{\circ}$ at $0.40{\pm}0.499$, $35^{\circ}$ at $1.34{\pm}0.657$, $40^{\circ}$ at $1.84{\pm}0.573$, $45^{\circ}$ at $0.76{\pm}0.649$, and they were significant(P<0.05). The degree of $40^{\circ}$ views were shown to yield good quality shoulder oblique images.

Purpose: To evaluate and compare the results of children with displaced supracondylar fractures of humerus treated with open reduction and pinning with closed reduction and pinning. Materials and Methods: From March 2002, we treated 17 patients with completely displaced supracondylar fractures under the age of 7 with a minimal follow up period of 6 months. 9 patients were treated with closed reduction and pinning and 8 patients were treated with open reduction and pinning. The clinical results were evaluated with Flynn's criteria. Time to bone union was also analyzed for these two set of patients. Results: The group treated with open reduction had 6 excellent and 2 good results for change in carrying angles, 5 excellent, 2 good and 1 fair results for motion loss evaluated by Flynn's criteria. The average time to bony union for this group was 5.8 weeks. The group treated with closed reduction had 6 excellent, 2 good, and 1 fair results for change in carrying angles and 7 excellent, 1 good and 1 fair results for motion loss. The average time to bony uinon for this group was 3.7 weeks. Conclusion: In treating completely displaced supracondylar fractures of humerus in children, the closed reduction method and open reduction method all showed good results. But the operation time, duration of hospital stay and time to union was somewhat shorter for the patients treated with closed redution and pinning.

Fibrous dysplasia is a benign pathologic condition in which the normal cancellous bone is replaced by the fibro-osseous tissue. It is found mostly in the femur, tibia, skull, rib, and humerus. Clinically it may develops pain, progressive deformity, and pathologic fracture. Curettage with bone graft has been the most popular treatment method thesedays. A 17-year-old female who had fibrous dysplasia of the humerus combined with multiple cystic lesion was treated by intralesional steroid injection into the lesion total 2 times. The follow-up plain X-ray which was taken 11 months after steroid injection reveals decrease in size and increase in bone density and cortex thickness. The follow-up MRI reveals significant decrease in size and signal intensity. The signal intensity was decreased to that of normal bone marrow in T2 weighted image. She complains no pain and lives symptom free in last follow-up at 2 years and 8 months after steroid injection.

Purpose: To evaluate the results of the compression plate fixation and autogenous bone graft in the management of humerus shaft nonunion. Materials and Methods: Eighteen cases were treated for humerus shaft nonunion using compression plate fixation and an autogenous iliac bone graft. The mean follow-up period was 28 months. Bony union was confirmed from the serial radiographs and the clinical outcomes were assessed according to ASES scoring system. Results: In 12 cases of initial plate fixation, the causes of nonunion were 6 cases of inadequate plate length, 2 with a broken plate, 2 with screw loosening, 1 infection and 1 noncompliance of a psychiatric patient. In 3 cases of initial intramedullary fixation, the cause of nonunion was a distraction of the fracture site. In 3 cases of external fixation, the cause of nonunion was inadequate fixation. All cases showed bony union after an average of 24 weeks. The clinical outcomes were 11 excellent, 6 good and 1 fair. Conclusion: In the treatment for nonunion, compression plate fixation with autogeneous bone graft after complete removal of the fibrous and necrotic tissue is believed to give satisfactory results.
