The ankle is a modified complex hinge joint consisting of the distal tibio-fibula joint (Syndesmosis), and the ankle joint proper(hinge joint), and is important in weight bearing, standing and walking. So, the goals of treatment of ankle fracture are anatomical positioning of talus in the mortise and regaining a smooth articular suface. Unless these requisites are achieved by treatment, post-traumatic arthritis is likely to occur. We analyzed 120 cases of ankle fracture, most of which were treated surgically by A-0 method, in Department of Orthopaedic Surgery, Hyundai Haesung Hospital from January, 1982 to December 1985. The results are as follows; 1. The most common victim was 3rd–4th decades man, and the cause was direct blow. 2. The most common type was pronation-external rotation type of Lauge-Hansen classification, and Type A of Danis-Weber type. 3. The more favorable result was noted in Danis-Weber type A than type B and type C,and noted worst result in pilon fracture. 4. Favorable results can be gained by semi-tubular plate in fibular fracture than any other fixation material. 5. On application of semi-tubular plate, there were no significant differences in results between that placed posteriorly and that placed laterally. 6. We did not transfix the distal tibio-fibular joint in stable Danis-Weber type C injury without any specific sequellae. 7. We obtained better result by removal of transfixing screw 6 weeks after operation. 8. We obtained good results with only 3 weeks immobilization after operation.

PURPOSE: To investigate the correlation between mammographic findings of infiltrating ductal carcinoma (IDC), patient age and pathologic grading. MATERIALS AND METHODS: The study included 103 cases of infiltrating ductal carcinoma in 102 women who during the preceding three years had undergone mammography and surgery. The mammograms were retrospectively reviewed by two radiologists. The mean age of the patients was 45.2 (range 26-74) years and the age distribution was seven in the 3rd decade, 37 in the 4th, 29 in the 5th, 24 in the 6th, and six in the 7th or above. Thirty-three lesions were histologic. Grade I, 59 were Grade II and 11 were Grade III. RESULTS: Ten (9.7%) of 103 cases, all of whom were younger than 50, were missed during mammographic diagnosis. On mammograms, primary findings of breast malignancy were found in 54 (74%) of 73 patients younger than 50 and 27 (90%) of 30 patients older than 51. Mass with or without microcalcification was found in 45 patients (62%) younger than 50 and in 26 (87%) older than 51. Nine (12%) and 3 (10%) in each age group showed secondary findings. There was no correlation between age distribution and histologic grading. Seventy-three percent of Grade I lesions and 78% of those of Grade III showed primary findings. Five lesions in each of Grade I and II were missed at mammographic interpretation, but this was not statistically significant (p=0.250). In all 11 Grade III cases, breast cancer were manifested as primary findings but this was not statistically significant (p=0.203). CONCLUSION: The majority of IDC were detected by mammography, but 9.7% of IDC patients, all younger than 50, were misdiagnosed. Most IDC was manifested as primary findings, particularly in patients aged over 51. There were no differences in pathlogic grading according to age distribution. All histologic Grade III lesions were detected by mammography.

Dermal melanocytosis such as nevus of Ota and extensive Mongolian spots are sometimes associated with hemangiomatous changes. Ota gave the designation of phakorriatosis pigmentovascularis to a spectrum of these combinations. We oLserved four cases of phakomatosis pigmentovascularis. They showed extensive, various dermal melanocytosis and widespread nevus flammeus. They exhibited signs of involvement of the systemic organs such as abnormality of electroencephalograrn, soft tissue hypertrophy and convulsion.

It has been generally assumed that eccrine poroma ariees from acroayringium, epidermal sweat duct unit. One of the characteriatics of thie structure is abaence of melanocytes and melanin granules among ite cells. Hmvever, a cornplete abeence of melanocytes and melanin granules in eccrine poroma is not invariable and a few reparts of such an occurrenee were presented, We report a case of eccrine poroma on the area below lateral malleolus af left foot. Microscpically melanin granules, confirmed by the use of Fontana Masson stain, were found in some of the tumor cells.

Becker's nevus or Becker's melanosis is a distinct clinical entity in which epimal thickening may be minimal and hairiness and pigmentation obvious. 1Ne report a case of 14-year-old female suffering from Beckers melanosis with multiple and extensive skin lesions. The electron microscope revealed that the melanocytes were bulky with increased melanogenesis and an increased number of melanosomes was found in the keratinocytes. In addition, a large number of melanosomes were seen individually in the keratinocytes.

In dealing with lateral condylar injuries of humerus, the chance of pitfalls and having a poor functional result with poor management is much greater because it is a physeal injury involving intraarticular surface. Lateral condylar physeal injuries of distal humerus have been regarded as Salter-Harris Type IV injury. But indeed, true Salter-Harris type IV injury of lateral condyle of distal humerus are rare. It should be regarded as Salter-Harris type II injury. Previously Milch classified the lateral condyle fracture of distal humerus as type I and type II after Stimson's description. It seems to be most useful to plan therapeutic modalities by classification of lateral condyle fracture on the basis of stage of displacement proposed by Jakob et al and Milch's type. Authors performed clinical analysis about lateral condyle fracture of distal humerus in children. Among 79 cases, who were treated at department of orthopaedic surgery, Hyundai haesung hospital from Mar. 1982 to Mar. 1988, it was possible to follow up in 30 cases. The result were as follows ; 1. The age incidence was confined from age of 3 to age of 12. Peak age was around 6. 2. Most of fractures were Milch's type II (75 cases) in contrast to Milch's type I (4 cases). 3. Precise differentiation of stage I and II displacement was needed for evaluation of stability of fracture and planning treatment modalities. 4. In case of stage II displacement, cast immobilization alone was insufficient. K-wire fixation was needed for prevention of displacement and better result. 5. In all of cases(30 cases) overgrowth of lateral condyle and spur formation were noticed but it has no clinical disabilities. 6. There were no significant differences of outcome between different fracture types and different stage of displacement. But significant differences of outcome were noticed how treatment performed. Accurate anatomical reduction and stable fixation was needed. 7. 2 cases of severe cubitus varus(20') were occured. In 21 cases, carrying angle were changed, valgus change were more common than varus change. It was thought to be relative undergrowth of lateral condyle of humerus and malunion as its causes. 8. In all cases, there were no loss of R.O.M.

Various methods of spinal instrumentation have been used for treatment of unstable fracture & fracture-dislocation of thoraco-lumbar spine. Recently, newly designed short segment fixation devices using pedicle screw were designed and there was a trend to use this posterior short segment instrumentation using pedicle screw. We have used AO internal fixator as posterior instrumentation for unstable spine fracture of thoracolumbar spine since November, 1987. Previously we used Harrington instrumentation and Luque rod wiring for treatment of unstable fracture of thoracolumbar spine and we reported the results of clinical analysis of those systems on Feb, 1987. We analyzed the clinical results of 93 cases those who underwent operative treatment using each posterior instrumentation system for unstable fracture and fracture-dislocation of thoraco-lumabr spine at our hospital from Dec. 1983 to Oct. 1989. Among that 93 cases, the Harrington instrumentation were 35 cases, Luque rod instrumentation were 36 cases and AO internal fixator were 22 cases. The results were as follows:1. The most commonly injured level was Ll (44 case) and followed by T12(33 cases, 86%). 2. By Francis Denis classification, Burst type fracture was most common(42 cases, 45%). 3. Change of kyphotic angle were checked on lateral X-ray view. There no significant differences between those groups using H-rod(58.64%), Luque-rod(54.8%), and AO internal fixator(60.1%) on immediate post-op X-ray. But there noticed least loss of correction of kyphotic angle when using AO internal fixator comparing with other groups. 4. The correction rates of height of anterior and middle column were checked by Denis-Edward method, there noticed best correction rate in AO internal fixator group. 5. The ROM of trunk were checked, there were no significant differences in H-rod, L-rod, and AO internal fixator group in long term follow up.
