Ankylosing spondylitis is a chronic inflammatory disease which most frequently affects the sacro-iliac joints of young men, and also the synovial joints of the whole spine. Bony fusion of these joints and ossification along the longitudinal ligaments lead to total immobility of the vertebrae. Sixty-two cases of ankylosing spondylitis treated at the Severance Hospital from June 1980 to June 1986 were analysed clinically and the followings were obtained. 1. The average age was 38 years and the sex ratio between the male and the female was 58: 4(Male=94%). 2. The most frequent location of pain was low back (32%), and the pain was usually bilateral (81%). 3. The main stiff regions were the hip joint (35%) and the lumbar spine (27%). 4. The most frequent joint affected was the hip (44%), and the extraarticular manifestations were pleuropulmonary disease (29%), gastrointestinal disorder (15%), iritis (10%), etc. 5. The characteristic X-ray findings were sacro-iliac changes (72%), facet joint blurring (53%), and syndesmophyte (37%). 6. Laborstory findings showed increased ESR (85%), positive HLA B-27 (97%), negative rheumatoid factor (94%), and the serum immunoglobulins snd complements were not decreased.

The depth of wound level is as important as the level of the tendon injury itself. And the timing of the operative procedure is an important factor. As a rule, tendons injured outside of the flexor sheath yield much better results than those injured within the sheath. The nutritional supply of the flexor tendons is not completely understood. Many elaborate studies have outilned the vascular anatomy of these tendons, and not all authors are in agreement. It is now clear that synovial fluid within the sheath supplies nutrition to the tendon much as synovial fluid in a joint supports cartilage. With this in mind, the present study was designed to determine the effect of exposing tendons for varying periods of time on the viability of the tendon and sequential morphological changes. The results are as follows: 1. Twelve hours after tendon sheath removal, collagen fibrillar dissociation and irregular surface of the tendon sheath were noted on the chicken flexor tendons by electronmicroscopy. 2. Superficial tenocyte necrosis was created after 24 hours of tendon exposure. 3. At 3 days, inflammatory cell infiltration and thickening of the outer synovial layer were noted. After 7 days, fibrosis of the degenerated tendon started from the exposed surface. 4. The fibrous connective tissue and new blood vessel infiltration into the tendon were progressed after 7 days. From these morphological results, any interference with the synovial environment leads to a regressive change of the flexor tendons immediately. It is suggested that delayed primary wound covering procedure within three days an after exposed tendon injury is ideal, and it should by done at least 7 days after tendon exposure.

Diabetes mellitus is one of troublesome disorder for the orthopaedic patient who should be operated on some other problems. Internist will advice and take care of them as far as diabetic problem is concern. However, orthopaedic surgeon should fully understand and follow every details about the condition of his own patient. Gamerin-Davalos hadclassified the diabetes mellitus into four types of potentiate, chemical and clinical diabetes. Potentiate form is not detectable at present method. The chemical and latent chemical forms are subclinical types and will be detected by the special examinations. In the orthopaedic practice, surgeon should keep in mind and perform proper tests for any suspecious symptomes or histories related to diabetes mellitus. Administration of insulin for the diabetes should be full doses but nerve be over-dosed. Neuropathy, vascular changes and infections are the common complications to diabetic patient and closely influence to the prognosis of major surgery. Ellenbery et al. had emphasized that the neuropathy is not a complication but rather a concomitant feature of diabetes mellitus. It may appear nerve root symptome to confuse with the herniated intervertebral disc. Vascualr change of the thickening of capillary basement membrane will causes gangrene of extremities and unexpected massive bleeding during surgery. Susceptibility of infection on diabetic patient is well known fact and in case of chronic osteomyelitis or tuberculosis of bone persist for long time without specific reason, surgeon should check once for the posibility of diabetes mellitus. Administration of any general anesthetic agents will elevate blood sugar level especially the ether, however, fluothane is a selective one at present. In case of surgery on diabetic patient, aceton uria and CO2 combining power should be checked closely for four to five days post-operatively. Blood sugar level should be kept slightly elevated during and post-operative period for diabetic patient. Surgeon should check his patient for any complications in case of increased dose of insulin is required post-operatively.

Five cases of congenital pseuduthrosis of the tibia were treated at Department of Orthopedic Surgery, Yonsei Medical Center from September 1971 to February 1982. In four cases, many cafe-au-lait spots were shown on the whole body skin, which are suggestive of neurofibromatosis. The evidence of hereditary factor is elicited on Case 2. Satisfactory bony union occurred in Case 1 & 3 in which the delayed autogenous bone graft was used. Among various methods of treatment of the congenitaeudarthrosis, in this study, the delayed autogenous bone graft and the free vascularized bone graft was recommended.

Low back pain and sciatica is one of the most frequent and troublesome problem in the orthopedic field. A study of the effectivity and reliability of the anterior interbody fusion with autoiliac bone graft for the spondylogenic and Discogenic back pain was done on 166 patients who had been hospitalized from January 1978 to December 1984. The approach to the lesion was retroperitoneal with anterior approach. The anterior interbody fusion was performed by using one block or two block from autoiliac bone. The status of the spine fusion after operation was decided by the plane roentgenogram or clinical sign, and the tomogram or dynamogram in some case. We analysed 116 patients having anterior fusionto study whether fusion rate has any relation with the number of the grafted bone, preoperative diagnosis and the level of fusion. At 9 months after operation, the clinical result was assesed and was compared between the group of the preoperative diagnosis. The following results were obtained from analysis of the cases studied. 1. The fusion rate for the grafted bone was 92.2%. There was no difference in fusion rates between the group of patients operated using one block and two-block. 2. The fate of the grafted bone could be categorized into 5 different types. 3. In patients with spondylolisthesis or spondylolysis, there was high incidence of non union.Also in terms of the vertebral level, the fusin between the L5-Sl showed high incidence of non union. 4. High fusion rate was obtained by using back brace without cast immobilization. The average duration of brace wearing was 6.6 months. 5. Overall clinical results were as follows:excellent or good 64.6%, fair 31.9%, poor 3.5%,and spondylolisthesis showed better clinical results than other diseases. 6. Post sympathectomy symptoms were noticed in 12 patients after operation and there were no permanent genitourinary problem.

Tibial tunnel placement during endoscopic anterior cruciate ligament (ACL) reconstruction has received increased emphasis in the recent literature. Tibial tunnel length is a factor that affect graft fixation, potential impingement, and graft abrasion. Appropriate tunnel length is a critical tecpnical consideration. A tunnel that is too long may make distal fixation and femoral tunnel placement difficult... A tunnel that is too short results in graft extrusion, necessitating supplemental fixation techniques. This grafl-tunnel mismatch can be avoided if fhe sum of the tibial tunnel length plus the intraarticular distance of ACL is equal to or greater than the graft tendon length plus 20mm (the minimum interference fixation possible when using the smallest available 20 mm long interference screw). Authors published an article to determine the reiationship between the length of patellar tendon and that of anterior cruciate ligament, to calculate the tibial tunnel length through the dissection of 19 cadaveric knees (ACL length (mm)=0.73 X Patellar tendon length-2.69 (p Anterior Cruciate Ligament ; Cadaver ; Humans ; Knee ; Patellar Ligament ; Tendons ; Transplants

Chronic compression or ischemia of the spinal cord in the cervical spine causes a clinical syndrome known as cervical myelopathy. Recently, a new term “degenerative cervical myelopathy (DCM)” was introduced. DCM encompasses spondylosis, intervertebral disk herniation, facet arthrosis, ligamentous hypertrophy, calcification, and ossification. The pathophysiology of DCM includes structural and functional abnormalities of the spinal cord caused by static and dynamic factors. In nonoperative patients, cervical myelopathy has a poor prognosis. Surgical treatments, such as anterior or posterior decompression accompanying arthrodesis, arthroplasty, or laminoplasty, should be considered for patients with chronic progressive cervical myelopathy. Surgical decompression can prevent the progression of myelopathy and improve the neurologic status, functional outcomes, and quality of life, irrespective of differences in medical systems and sociocultural determinants of health. The anterior surgical approach to the cervical spine has the advantage of removing or floating the intervertebral disk, osteophytes, and ossification of the posterior longitudinal ligament that compress the spinal cord directly. The posterior surgical approach to the cervical spine is mainly used for multisegment spinal cord compression in patients with cervical lordosis. In this review article, we addressed the pathophysiology, clinical manifestations, differential diagnosis, and treatment options for DCM.
