The Treatment of Acromioclavicular Separation / 대한정형외과학회잡지

Of the shoulder injuries in trauma, none are more common than those involving the acromioclavicular joint. There are many procedures described for treatment of injuries of the acromioclavicular separation but difficulties continues to be encounted. To know the functional anatomy of this joint and mechanism of injuries makes more proper treatment. We operated the 16 cases of acromioclavicular separation in the Dept of Orthopedic Surgery, Kyung Hee College of Medicine from January 1975 to August 1978. The following results were obtained. 1. This injuries is more prevalent in male with peak incidence in the third and fourth decades. 2. The mechanism of injuries were traffic accident, falling down and the other direct injuries with in orders. 3. The difference of distance between coracoid process and clavicle gives the information of Type II and Type III. 4. The operative procedures in Type II and Type III are good treatment of acromioclavicular separation.

Clinical Study of Meniscus Tears / 대한정형외과학회잡지

46 knees with injured meniscus diagnosed by the use of history and physical examination as well as by arthrography were meniscectomized from January in 1974 to June in 1978. Statistical analysis of data obtained from the histories, physical examinations and arthrographic studies of 46 knees with a mean follow up 6 months after meniscectomy revealed as follows. 1. Lateral meniscus injuries were higher incidence than medial meniscus. 2. In the posterior horn of the medial meniscus and in the middle third of the lateral meniscus on the injured location were more frequently encountered. 3. To compare the results of twe methods of diagnosis were obtained with 67% accuracy by the use of history and physical examination and with 85% accuracy by arthrography 4. We should be able to diagnosis with 91% armed with a history and physical examination and an arthrogram. 5. As being the excellent results after meniscectomy were classified with 78%.

Review of Trochanteric approach in 285 Total Hip Arthroplasties / 대한정형외과학회잡지

This paper is a consecutive series of total hip arthroplasties were performed over 6 years period by the same group surgeons utilizing the Charnley method as well as the lateral approach with trochanteric osteo. tomy. Trochanteric reattachment was accomplished in 285 hips and method of reattachment were basically standard Charnley technique which we used in most of our series. In addition, some modification of original Charnley technique which we used in early this trial were also included for this study. As far as trochanteric complications are concerned, there are 18 cases of hips where there was wire breakage, proximal drift of greater trochanter and 6 established cases of nonunion also reported. By the use of wire mash, we have performed a revisional surgery which has re-inforced of the greater trochanter. This was the case when the greater trocyhanter was very osteoporotic. Finally, biomechanical considerations of the re-attachment of the greater trochanter and new Charnley staple clamp method were introduced with review of our cases and analysed for technical failures.

Congenital Hyperextension of the Knee: Report of a Case / 대한정형외과학회잡지

Congenital Hyperextension of the Knee is a extremly rare deformity, in which the tibia is displaced anteriorly in relation to the femur. It is usually classified into three subtypes according to severity of the status: genu recurvatum, subluxation and dislocation. (Curtis and Fisher) We experienced a genu recurvatum type of congenital hyperextension of the knee in June, 1976.
