Calcaneal fractures of 82 feets in 68 patients which were treated at the Dept. of Orthopedic Surgery, St. Mary's Hospital since 1974 to 1978 were cllnically analysed, and the following results were obtained. 1. Of 68 patient 50 patients were male and 18 female. Their ages ranged from 9 to 58 years and averaged 33 years. 2. Fourteen patients had both calcaneal fractures, and the spine fractures were associated in 14 patients with calcaneal fractures. 3. Of 82 fractures 50 fractures were Rowe's type 5. Of these type 5 fracture 14 cases of tongue type were treated by axial pin flxation and favourable result were obtained. All the other types of fractures were treated conservatively. 4. After treatment, the most common complication after treatment was presistant foot pain. The commonest site of residual pain was beneath the lateral malleculus. Of 82 fractures 22 cases had this complaint. This residual pain occured in the seventeen cases type 5 fracture. 5. Residual flat foot deformity and weakness of triceps power were clinically not significant if the residual foot pain is nat associated with those two factors.

Patients with rickets frequently are seen by orthopaedic surgeon with complaints of growth disturbance, limb deformity, weakness, and multiple fracture. Among them, bow leg deformity is the most common and difficult orthopaedic problem. In growing child, however, if effective tretment is given sufficiently in early age and early disease process, the deformities usually correct spontaneously and there is little need for orthopaedic treatment other than careful observation. The orthopaedic treatment may be required to correct deformities that cannot be expected to improve with growth. A clinical study was done for 11 cses of rachitic bow leg deformity who were treated at the department of orthopaedic surgery, Catholic medical College and Center from Jan. 1978 to Dec. 1981. Results obtained were as follows: 1. The most common patients age group was in 1 to 2 years of age and there was no sexual difference. 2. Associated deformities with rachitic bow leg were rachitic rosary (5 cases), double wrist (3 cases), coxa vara (1 case), and Harrison's groove (1 case). 3. Low Ca * P solubility product, below the level of 30 (mg/dl)2 suggested active form of rickets in all cases. 4. Laboratory values such as Ca * P solubility product and alkaline phosphatase improved at 3 weeks after administration of vitamin D in 7 cases, 3 at 6 weeks, and no improvement in one case even at 6 months after treatment. 5. Six months after treatment, the average amount correction of tibiofemoral angle was 9° (43.7% of initial angle) in group 1, 13.3° (47.0%) in group II, 4.9° (29.6%) in group III, and 3.3°(25.6%) in group IV. 6. Through this study it is suggested that the more growth correction of the rachitic bow leg deformity in a younger child below the age of 2 is obtained with growth by treatment, whereas a little or no growth correction can be expected after the age of 3 or 4 years.

Seventy consecutive ipsilateral fracture of the femur and tibia in sixty-eight patients from December 1974 through December 1984 treated at Severance Hospital were analysed in clinical and radiological aspect. 1. Fifty-nine patients were male and nine patients were female. The male patients were more injured in the ratio of 6: 1. The avarage age was 34. 2. The main cause of injuries were traffic accidents; 59 patients. (86.8%). 3. The majority of the fractures were shaft fracture; for example, femur shaft 57% and tibia shaft 47%, The open fracture of the tibia was 34% and the femur was 17%. 4. There were 24 cases of concomitant fracture and dislocation of other sites. A fat embolism was disgnosed in 4% of the patients. Four patients had died one month after sustaining injuries. 5. Over-all, a good or excellent functional result was achieved in 76% of the patients treated with internal fixation of both fracture, 65% of the patients with intexnal fixation for the femur fracture only and 35% of the patients managed conservatively.

The head patient with musculoskeletal trauma is a challenge to the orthopedic surgeon and its incidence is increasing markedly with the development of modern culture and a high velocity motor vehicle. So, for the purpose of studying the difference between lower extremity fracture concomitant with head injury and only lower extremity fractured patients, we studied the radiologic bone union time, serologic test and heterotopic ossification. For the control group we analysed each 10 patients of only femur and tibia fractures. The following clinical results were obtained by analysis of 46 patients of lower extremity fracture concomitant with head injury, experienced in the Department of Orthopedic Surgery, Yonsei University College of Medicine in past 5 years from Jan. 1980 to Dec. 1984. 1. The mean age was 24.5 yrs old (2~6 yrs old) and the prevalent age was 1st and 3rd decade, and the sex ratio between males and females was 2.8: l. 2. The most common mode of injury was auto-pedestrian injury (84.8%) and the other was falling down injury(15.2%) . 3. The common brain injuries were cetebral contusion with skull fracture (37.0%) and cerebral contusion only(34.8%) . Among 26 patients whos mental states were not alert, 23 patients recovered mental states completely. 4. Serum Calcium, Phosphate, and Alkaline Phosphatase level were no difference between the head injury with lower extremity fractured patients and only lower extremity fractured patients. 5. There were no evidence of early bony union in the patients with head injury. 6. The formation of callus were abundant in the patients of lower extremity fracture with head injury rather than the only lower extremity fractured patients. 7. The incidence of heterotopic ossification was 10.9% and all patients with heterotopic ossification were treated with physiotherapy and all patients recovered fully. 8. The incidence of complication was 17.3% and there was no fat embolic patients. In conclusion, there was no evidence of early bony union, but the callus formation was abundant in the patients of lower extremity fracture concomitant with head injury.

Limb salvage operation in primary malignant bone tumors is increasing recently, according to the improvement of diagnostic methods, surgical technique and adjuvant chemotherapy. The purpose of this study is to obtain the interim results of survival rate and the functional grade of the limb in primary malignant bone tumors treated by limb salvage operation. Between 1985 to 1993, 63 primary malignant bone tumors treated by limb salvage operations. Tumor prosthesis arthroplasty was performed in 49 patients, resection arthrodesis in 9 patients, and IM nailing with cement molding in 5 patients. Autoclave autograft was combined in 2 patients. Adjuvant chemotherapy and postoperative radiotherapy were performed in selected patients. The average follow-up period was 50 months(ranged 12 months to 116 months). In the cases of osteosarcoma, estimated survival rate was 61.9% based on Kaplan-Meier survival plot. In the parosteal sarcoma, the survival rate was 87.5% and 80% in chondrosarcoma patients. According to functional grading by Enneking, 66% was excellent, 20% was good, 11% was fair and one patients was poor. Complications occurred in 16 patients:wound infection was developed in 6 patients, local recurrence in 4, peroneal nerve palsy in 2 patients and femoral stem loosening in 2 patients. Fracture in resection arthrodesis and pulmonary metastasis were also occurred. Reoperation was performed in 10 patients at average 31 months after initial operation. Revision tumor persthesis arthroplasty was performed in one patient due to local recurrence and in 2 patients due to femoral stem loosening. Three amputations were done due to recurrence of tumor. IM nailing with cement molding was performed in one patient due to deep infection and repeated arthrodesis was done in a fracture patients. Scheduled custom-made tumor prosthesis arthroplasty was performed within a year in 2 patients treated with IM nailing with cement molding. In conclusion, with the careful preoperative assessment, adjuvant chemotherapy and skillful surgical technique, limb salvage operation would provide the primary malignant bone tumor patients for longer survival and better quality of life.

Lipoma is one of the unusual benign breast neoplasms and usually manifests at fatty breast of women at the age of 40 to 60. We experienced a case of large breast lipoma nearly replacing the whole left breast parenchymal tissue with mammographic finding of well-defined radiolucent mass, sonographic finding of hyperechoic mass with disorganized echopattern and computerized tomographic finding of very low attenuation mass, characteristic to adipose tissue, in a young woman of her dense breast.

Pilomattiaoma, aften called calcifying epithelioma of Malherbe, is a benign tumor originating from the outer root sheath cell of the hair follicle and extending into the hair matrix, Pilomatricoma usually occurs as a single, asymptomatic dermal or subcutaneous nodule. Multiple lesions are quite unueuel, comprising only 2-3.5% of cases. We report two patients with multiple pilomatricoma.

We present a case of angiographically-confirmed transverse and sigmoid sinus thrombosis, image with MR, in a 20 year old male with a history of otitis media and maxillary sinusitis. T1-weighted image demonstrated an isosignal intensity mass with tubular-shaped low signal intensity in right transverse and sigmoid sinus. The thrombus had high signal intensity on T2-weighted image. The signal intensity of the thrombus on Gd-DTPA enhanced T1-weighted image was unusually high similar to that of transverse sinus. Although dural sinus thrombosis has a non-specific MR signal intensity, findings of MRI in this case may serve as an aid in future evaluation of venous thrombosis.
