It is likely that the peroneus longus tendon acts as a structure resisting the varus force upon the first column of the foot. Our study was designed to examine the possibility that absence of the peroneus longus insertion into the first metatarsal and first cuneiform will destabilize the first metatarsal. The fresh frozen cadaveric specimens of the lower leg were obtained. There were six right feet. The specimens appeared normal visually and roentgenographically. The tibial remnant was rodded by an intramedullary rod and the sprcimen was positioned in a specially designed rig so that standing position of the foot was simulated. The tibia was then loaded with twenty pounds. To obtain reproducible radiographic landmarks radioopaque beads were implanted underneath the level of the cortex through small drill holes in the following location : First metatarsal (one bead in the head, another bead in the base). The second metatarsal (again one bead in the head, on e bean in the base). To simulate the contraction of the peroneus longus muscle a suture was placed into the proximal end of the tendon, brought through two pulleys and loaded with a five pound weight. To create a varus force on the first metatarsal a stab incision was made over the base of the first metatarsal at its medial aspect and a suture was passed through the base of the first metatarsal. The suture was guided over a pulley and loaded with ten pounds. The second metatarsal head was fixed to the bottom of the rig with a smooth Steinmann pin. At this point an AP roentgenogram was taken of the footto assure proper positioning of the foot. Thereafter, the soft tissue between the first and second toe were cut sequentially : (1) Transection of the skin of the first web space both dorsally and plantarly. (2) Transection of the adductor hallucis tendon and the intermetatarsal ligament. (3) Transection of the peroneus longus tendon at its insertion. Each step in the transaction of the soft tissues was followed by another X-ray examination. In each roentgenogram the proximal and distal beads in the first and second metatarsal were connected by a line and the angles between those lines were measured. The results were statistically analyzed with the Friedman Chi square test between each step of the ten feet. Following the first and second step angular changes are not significant. Following the final step, adding release of the tendon insertion of the peroneus longus, the angle changes from 15.95 to 20.55 degrees (difference 4.60 degrees) and this is significant (p < 0.05).

One of the common cause of the acquired adult flat foot is posterior tibial tendon insufficiency whose etiology and development is different from that of congenital flat foot, and various methods, such as synovectomy, tendon transfer, calcaneal osteotomy and arthrodesis, can be used to treat the symptoms. The sliding calcaneal osteotomy has been recently introduced by Mark Myerson. The basic concept beneath this treatment is that by displacing distal part medially after a calcaneal osteotomy, the valgus strain in hindfoot can be relieved to place the joint back to the normal position. In order to find out the effect of the sliding calcaneal soteotomy on the flat foot, we measured the changes in the strain in the upper medial spring ligament complex underneath the talonavicular joint after the operation. Four right hand four left fresh frozen cadaver foot specimens, which included the distal half of the tibia were utilized. The spring ligament was isolated with its origin at the sustentaculum tali and insertion on the navicular. At the medial calcaneus the soft tissues were periostially dissected and a small incision was made over the lateral calcaneus for the purpose of visualization. For each specimen a calibrated open liquid metal strain gauge was secured at the origin and insertion of the ligament with superglue and the gauge was sutured along the length of the superomedial portion of the spring ligament complex allowing for the gauge to slide freely. A tibial rod was driven into the intramedullary canal and the foot was always placed in the neutral plantigrade position in the test fig such that the rod was vertical at all times. A initial strain measurement was obtained with only the weight of the platform (19.6N) on the tibia. Weights were added in 7 increments to a total 472 Newton and strains were recorded. Three trials were conducted. The specimens were then removed from the rig and an oblique osteotomy were conducted. A repeated measures analysis of variance showed a significant (p < 0.001) reduction in strain following the osteotomy. To conclude, the direct measurements support the concept that a calcaneal osteotomy provides an alteration which is favorable to unloading the medial arch.

The congenital tracheoesophageal fistula without atresia of the esophagus is considered a rare variant, and the literature concerned to the tracheoesophageal fistula fistula without atresia is little in adult especially. The 22-year-old male was admitted to Yeungnam University Hospital with his chief complaints of weight loss (6 kg/6 months), abdominal discomfort, and intermittent coughing. The diagnosis was made by the endoscopy and esophagography. The fistula was 1.5 cm in diameter, 0.5 cm in length. The level was around second thoracic vertebra. The operation was performed transpleurally through the right third intercostals space and the fistula was secured with interrupted silk suture after division. The fibrotic adhesion was seen around the tracheoesophageal fistula. The postoperative course was uneventful, and postoperative esophagogram revealed no extraluminal leakage. Herewith we report this unusual case of isolated tracheo-esophageal fistula with review of literatures.

Haglunds deformity is a prominence at posterosuperior portion of the calcaneus. Extrinsic irritation on this prominence can give rise to retrocalcaneal bursitis or Achilles tendinitis. Partial resection of the posterosuperior aspect of the calcaneus was performed on 7 heels with Haglunds disease. All patients were reviewed both by radiographic examination and by questionnaire after an average 14.5 months. All but one patient showed an excellent result in a view point of pain relief. The average passive dorsiflexion angle of the ankle was improved from 5 to 25 degree, postoperatively. There was no complication such as recurrence, wound problem or paresthesia.

The Journal of the Korean Orthopaedic Association 1990;25(4):1257-1262
A neglected Monteggia fracture can pose a significant clinical problem because of decreased range of motion of the elbow, increased cubitus valgus, progressive damage and elbow instability. Factors leading to misdiagnosis include swelling of soft tissue, overlying of bones on radiographs and lack of inclusion of the elbow on the radiograph at the ulnsr fracture. Therefore, a radiograph that includes the elbow at the ulnar fracture should be taken. A line drawn through the shaft and head of the radius into the elbow should align with the capitulum in any projection, thereby assisting in the correct diagnosis. Three cases of neglected Monteggia fracture were treated by open reduction of the radial head with repair or reconstruction of the annular ligament and osteotomy of the ulna, and satisfactory results were obtained.

In children, the supracondylar fractures of the humerus are common in elbow region, and often associated with various complications and problems in treatment (ie,Volkmann's ischemic contracture, cubitus valgus or varus deformity, rotational deformity). The results of reduction can be measured by Baumann's angle, carrying angle, trochlea-capitellum angle, and displacement of distal radial styloid process on radiological study. So we have made experiments on the process which various three dimensional displacements reflected into two dimensional Baumann's angle and humerocapitellar angle. And we investigated the process of rotation, through various radiological studies by means of molded models of humerus. The results were as follows:l. In experiments, AP & lateral X-ray studies showed no change in rotation of proximal segment of fracture with fixed distal segment of fracture. 2. On the other hand, AP & lateral X-ray showed significant change, in rotation of proximal fracture segment with distal segment of fracture. 3. Supracondylar rotation angle(S.R.A.)depicted as the ratio of the length of proximal fracture width minus that of the distal fracture width in lateral view, to the length of distal fracture width in AP view minus that of the distal fracture width in lateral view. 4. According to the modified Mitchell result, S.R.A. to the result of treatment was average 7.6 degree in excellent group, 15.2 degree in good group and 29.3 degree in unsatisfactory group.

Prurigo pigmentosa is a chror ic pruritic inflammatory dermatosis characterized by erythematous papules in a reticulated pattern that resolve leaving a reticulated, mottled hyperpigmentation and rapidly response to dapsone therapy. Most cases that have been reported are from Japan. We report two cases of prurigo pigmentosa in a 21 year-old female and a 23-year-old female. Histopathologic findings of erythematous papules showed exocytosis, spongiosis, liquefaction degeneration of basal cell layer and perivascular lymphohistiocytic infiltration on the upper dermis. We treated them with dapsone, 100mg daily, which resulted in a remarkable regression of the ery thematous papules and improvenien of pruritus.
