2.The Effect of Orthopaedic Operations upon Postoperative Arterial Oxygen Tension
The Journal of the Korean Orthopaedic Association 1976;11(1):104-109
To 48 adult patients general and spinal anethesia was administered for elective orthopedic (intra-thoracic and extremity) and abdominal(general and gynecological) operations. Radial artery was cannulated and postoperative change of PaO2 was observed for 7days. The results are as follows: 1) General anesthesia administered for operations on the legs results in a reduction of PaO₂ which is maximal immediately after discontinuation of anesthesia, gradually returns toward normal in a 3-hour period, and becomes normal on the first postoperative day. 2) General anesthesia administered for thoracomy and laparotomy is followed by the same early changes, which do not return toward normal in the first 3 hours. Reduciton of PaO₂ persists, and PaO₂ continue to deteriorate for several days, not completely returning to normal even 7days post-operatively. 3) When spinal anesthesia is administered for laparotomy, PaO₂ does not begin to fall untill several hours after the end of operation. The subsequent course follows as that in 2, above. 4) When spinal anesthesia is administered for operation on the legs, PaO₂ does not change significantly throughout the postoperative period. 5) Thus, it is concluded that late forms of postoperative hypoxemia is influenced primarily not by the method of anesthesia, but by site of operation.

3.Pulmonary Function in Spine Deformity
The Journal of the Korean Orthopaedic Association 1978;13(3):343-351
The deformed and rigid spine presenting moderate to severe kyphosis and scoliosis results in a restriction of function of the lung best characterized spirographically by a reduction in vital capacity. When the lesion involves the thoracic spine, restriction of function is more marked. Spinal deformities such as kyphosis and scoliosis develop from various causes. Tuberculous spondylitis, a main cause of kyphosis and scoliosis, is increasingly found in Korea. Cardiorespiratory dysfunction caused by spinal deformity poses another problem besides the spinal deformity perse. To perform therapeutic measures such as Harrington instrumentation, with or without preoperative localizer cast and halofemoral traction, as well as anterior interbody fusion, evaluation of pulmonary function and arterial gas analysis preoperatively is helpful to prevent and reduce postoperative cardiorespiratory failure or complications. The authors have reviewed the results of arterial gas analyses and pulmonary function tests on 35 cases of scoliosis and 60 cases of kyphosis done at the Department of Orthopedic Surgery, Seoul National University Hospital, from January 1975 to February 1978. The results were as follows: 1. Average degree of scoliosis in 35 cases was 89; vital capacity 60% of normal, and maximum breathing capacity 72%. Average degree of dorsal spine kyphosis in 38 cases was 93.5; vital capacity 38%, and maximum breathing capacity 73% Average degree of lumbar spine kyphosis of 22 cases was 79; vital capacity 77%, and maximum breathing capacity 84%. 2. Static values for pulmonary function such as vital capacity and dynamic values such as maximum breathing capacity hed a significant negative correlation with the severity of scoliosis and kyphosis. 3. Decrease in vital capacity due to scoliosis and kyphosis correlated positively with decrease in maximum breathing capacity. 4. Arterial oxygen saturation had a significant negative correlation with the severity of scoliosis and kyphosis.

6.Treatment of Large-gap Non-union in Long Bone Using a Tibial Cortico-cancellous Bone Graft and Heavy Duty Plate Fixation

When the non-union gap in a long bone is more than half of the diameter of the bone at that level, it presents a significant challenge to traditional bone grafting technique. Even if there are several good ways for this problem, such as shortening, traditional various bone grafting, electrical stimulation and free vascularized bone graft, most of these techniques have some difficulties to maintain the stability of fracture post-operatively, and we have to keep their extremities into a cast or external fixator so long. So we have attempted to treat the large osseus gap non-union in long bone with fixation of heavy duty or condylar plate on one side of fracture for fracture stability, a long tibial corticocancellous strut graft on the other side of fracture for fracture stability and rapid bony union, and extensive cancellous chip bone graft between the plate and tibial graft to enhance the bony union. We have experienced 9 cases of large osseus gap non-union in long bone with this technique from March 1981 to September 1986 at the department of orthopaedic surgery, St. Mary's hospital, Catholic University Medical College. 1. Their, 7 males and 2 females, average age was 38 years old, with a range of 24 to 53 years old. The distribution of the involved bone was 6 femur, 2 humerus, 1 radius and ulna with 1.4 years of average duration of non-union, ranged from 7 months to 2.4 years. The average gap from normal bone to normal bone was 4.8cm, with a range of 2.7cm to 7.4cm. The average number of previous surgical procedures was 4, with a range of 2 to 7. Four of the nine patients had quiescent osteomyelitis. 2. Post-operative immobilization with splint or cast was applied for 6 weeks for upper extremity and 8 weeks for lower extremity followed by active R.O.M. exercise and non-weight bearing crutch walking. 3. Five of the nine cases(55.6%) had completely bony union. This occured on an average 8 months post-operatively and was faster in the forearm bones and femur than in the humerus. An additional cancellous bone graft was done in two. But other two of the patients had subsequent amputation because of recurrent and uneontrollable osteomyelitis stirred up by the surgery. 4. This procedures was proved to be one of valuable adjuvant method in treatmqnt of large osseous gap non-union of long bones.

Monilethrix is a rare hereditary disorder of hair which was described by smith in 1879. The scalp hair is most frequently affected but the body or sexual hair are rarely affected. The affected hair shows periodic constrictions that break easily, so the hair could not grow more than a few millimetere long. It is thought that the node of the affected hair is normal and the thin internodal segment is deficient in hair matrix. Keratosis pilaris is generally an associated feature. We experienced a case of monilethrix with keratosis pilaris. The 4 years old male patient with monilethrix affected only scalp hair with keratosis. The family history was non-contributory.

The authors observed 2 cases of poikilcdermatomyositis who were 16 and l0 years old female. The former visited our dept. due to rashes on the anterior portion of right thigh with 3 months duration. The skin lesion revealed mottled skin pigmentation, telangiectasia, atrophy, and cigarrette paper like wrinklings. On the palpation, hardness and tenderness in the lesion were felt. The latter visited our dept. due to weakness of the right lower extremity for 3years. The skin lesion revealed the same feature as the former but more prominent. Histophthologically, P.V.A. patterns are seen in the both skin lesions. The epidermis shows moderate atrophy of St. malphigi and flattening of reteridges. The dermis is edematous, vascular dilatations, and cellular infiltrations, most of lymphocytes, around the blood vessels. The muscle biopsies for the Quardriceps Femoris sbow Dermatomyositis patterns which the muscle bundles are degenerative changes and many cellular infiltrations, chiefly of lymphocytes, are seen between the muscle bundles. Diagnosis was confirmed by the clinical and histological pictures. These patients were markedly improved by the prednisolone therapy.
