Reconstruction nf torn cruciate ligament by using fascia lata, hamstring tendon and patellar tendon has been accompanied not infrequently with such complication as the avascular necrosis and/ or degeneration of the graft with eventual stretching. Normally the knee resists invaision by any tissue not covered by synovial membrane except the meniscus, which is a fibrocartilaginous structure and is not dependent on vascular supply, but is nourished by synovial fluid. The method using the meniscus in this procedure would be superior to the above methods would also entail less complication. In the two knee injuries, the patella and femur fracture in case 1 and the posterior dislocation in case 2, the torn posterior cruciate ligaments were reconstructed with torn lateral menisci. The results were good in both with normal stability.

With the improvement of economic conditions and medical care, the average life span has increased, thus making geriatrics an important consideration in the medical field. Degenerative changes of the cervical spine in aged are not uncommon. Also it is well known tha subjects with radiologic features of cervical spondylosis may be symptom free. On the other hand, cervical myelopathy may occur in the presence of minimal spondylosis as shown radiologically. This discrepancy between symptoms and radiologic features seems to be attributed to the differences in the initial structure of the cervical spine. The authors surveyed at random the various radiographic measurements of 300 Koreans having normal cervical spines and 120 Koreans with cervical spondylosis. The results of the survey are as follows: 1. Osteophyte was noticed more frequently at the 3 rd, 4 th and 5 th cervical vertebrae. 2. Lordosis angle was greater in spondylosis group than in normal group, which might be attributed to paravertebral muscle spasm. 3. Normal sagittal diameter of the canal decreased between C3-C6 and the narrowest was at C4 level. The sagittal diameter, on the average, was 1.5 mm shorter than in European population and 1 mm longer than Japanese. This might be attributed to the difference in the body height. 4. In the normal spine group the average interpedicular distance was greatest at the 5 th, and 6 th cervical vertebra. In the cervical spondylosis group the average interpedicular distance was greater than in normal population it was greatest at the 5 th and 6 th cervical vertebra.

A case of Cleido-Cranial-Dysostosis, which characterized by deficient formation of the clavicle with delayed and imperfect ossification of the cranium, associated with other anatomical errors, was experienced at The Department of Orthopaedic Surgery of Kyung Hee University Hospital in January 73. We report this rare and interest case with reference review.

The suture materials influence the success of microvascular anastomosis importantly. The purpose of this experiment is to observe the effect of absorbable suture material and nonabsorbable suture material in microvascular anastomosis. The study was carried out on one side of carotid arteries of fourty rats which were anesthetized intraperitoneally with urethane. The experimental procedures differed in two groups, Group A in which the carotid artery was sutured with 10-0 monofilament polyglycolic acid, Group B in which the carotid artery was sutured with 10-0 monofilament nylon. Gross and histological examination were used to compare the results of end to end suture above two suture material. The results were as follows. 1. Nylon had greater tensile strength and ease of handling than polyglycolic acid, but held knots poorly. 2. Polyglycolic acid had difficult handling and lesser tenslie strength than nylon, but held knots hardly. 3. Polyglycolic acid had high patency rate, some lesser tissue response than nylon.

Bone marrow pressure is neither arterial pressure nor venous pressure of extremity, that is thought the precapillary pressure of bone. It is different between long bone and flat bone, and is also different in various site of the bone. Author measured bone marrow pressure of 84 normal femoral heads of Korean adults for basic data of early diagnosis of avascular necrosis of femoral head. The results are followings : 1. The baseline bone marrow pressure of Korean healthy adults is average 22.5 ±7.2mmHg. 2. The most significant change of bone marrow pressure in stress test is observed at 5 min. after injection of 5cc normal saline. 3. The increase of bone marrow pressure at 5 min. after stress test was average 7.4 ±4.4 mmHg. 4. Sex and age factors do not influence bone marrow pressure.
