Spinal Stenosis / 대한정형외과학회잡지

Spinal stenosis is defined as diminition in the size of the spinal canal that produces nerve entrapment resulting in symptoms, the most common of which is low back pain & radiating pain to leg. The central spinal canal contains the dura and other meninges, and inside these, the nerves of the cauda equina. The nerve root canal contains the spinal nerve from the point which the dura leaves the intervertebral foramina. Each foramen is a door through which the nerve enters to the nerve root canal. In its canal the nerve passes behind the disc and then in front of the superior articular process of the lower vertebra. Pathological and anatomical changes by various cases can produce narrowing of the central and nerve root canal. But they are sometimes not important because they are not severe enough to cause nerve entrapment and such medical treatment, Spinal stenosis is only significant when nerves are entraped, indicated by severe leg pain and sometime by sensory and motor changes. Spinal stenosis is classified into two groups: congenital and acquired. Among acquired groups, the combined type is most common and significant. Authors have experienced 61 cases of spinal stenosis and among these, 58 cases were treated surgically between 1981 and 1984 at the Department of Orthopaedic Surgery, Eulji Glneral Hospital, Daejeon. The following results were obtained. 1. There were 52 males and 33 females, and peak incidence in 5th and 6th decade(69%) 2. The most common type by Arnoldi's etiological classification was combined type(69%) 3. The most common chief complaint on admission was low back pain and radiating pain to leg (43%) 4. The most common sign was limitation of lumbar hyperextension (75.9%) and S.L.R.test was positive in only 12 cases(20.7%). 5. The common findings of myelography were hour glss appearance (39.7%) and complete block (27.6%), and simple radiologic findings were hypertrophy of facet joint, osteophyte formation in the periphery of vertebral bodies involved and narrowing of disc speace. 6. The A-P diameter of spinal canal was between 14.44 mm and 14.97 mm in simple findings, and the A-P diameter of dural sac between 8.10 mm and 9.19 mm in myelography. The spinal index was between 1:4.90 and 1:5.60. 7. Decompressive surgery was done in the 2 levels in 39 cases (67.3%), 3 levels in 10 cases (17.2%) and 1 level in 9 cases (15.5%). Discectomy was done in 40 cases (69%) and partial laminectomy was done in 58 cases (100%). 8. The most common site was L3,4-L4,5 (36.2%).

A Clinical Study of Low Back Pain / 대한정형외과학회잡지

As Kelsey stated “Four out of five individuals will have a significant complaint of back painat one time or another in their lives and impairment of the spine are the most frequent cause of time lost from work”., low back pain affects the quality of life for just about everyone, medical and economic impacts of low back pain are enormous. Nevertheless, neither the government not industry has been seriously involved in the study of the cause, prevention, and management of back pain. The purpose of this study was to review and analysis the clinical materials of low back painand draw differences, if any, between discogenic and stenotic low back pain. Three hundreds and fourty nine cases suffering from low back pain and/or sciatic pain, excluded fresh traumatic and inflammatory conditions of the spine, have been admitted and treated at Dept. of orthopaedic surgery, Eul-Ji General Hospital, Dae-Jeon from May, 1981 to April, 1984. They were consisted of H.N.P. (172 cases), Spinal stenosis (61 cases), Spondylolisthesis (42) cases), Degenerative joint Disease of the spine (48 cases), and Others (26 cases). Among them, two hundred and twenty six cases who were followed more than four months were mainly subjectecl to this study.

A Case of Fibromatosis Associated with the Skeletal Change in Childhood / 대한정형외과학회잡지

Fibromatosis in childhood is a rare tumor and also prone to aggressive behavior. This tumor may spread to involve contiguous soft parts and osseous structures, but does not metastasize. We experienced a case of fibromatosis in an 12-year-old giri who complained of palpable masses in the region of the right buttock and right foot. The case has been followed for 6-years since February 1973. Bony change has occured even after several attempts of surgical excision but a distant metastasis has not occured.

Direct Bone Invasion of the Squamous Cell Carcinoma Arising from Chronic Osteomyelitis and Burn Scar: Report of 4 Cases / 대한정형외과학회잡지

Squamous cell carcinoma is a malignant tumor arising from the epidermis or its appendages, Squamous cell carcinoma of extremity comprises approximately 1 to 2 percent of all squamous celi carcinoma and of these 0.2 to 1.7 percents are secondary to chronic osteomyelitis and 2 percents are secondary to the burn scar. We experienced 4 cases of squamous cell carcinoma invading bone directly, of these 2 cases are secondary to chronic osteomyelitis and 2 cases are secondary to the burn scar. With prompt and aggressive surgical treatment the prognosis is good. Routine regional lymphadenectomy is unnecessary because in most instances enlarged nodes are inflammatory and subside after amputation.

Treatment of the Infected Ununited Fractures of the Tibia by Posterior Bone Graft / 대한정형외과학회잡지

In treatment of infected ununited fractures of the tibia, We have solved this disastrous problems by posterior bone graft through posterolateral approach. By this posterior bone graft, We can achieve both bone union and infection contral simultaneously. The results were as follows: 1. Total cases of the infected ununited fractures were 17 cases, among them 16 cases were open fracture initially. 2. They occured more commonly in young adult, 7 cases(41%) were in 4th decade, and all cases were male. 3. Tibial union was achieved in 16 cases and one patient can not walk without brace due to ain on fracture site. 4. Infection was cleared in 16 cases, but one case had intermittent drainage of pus. 5. The most common complication was stiffness of the ankle and tarsal joint. 6. There was no infection in grafted bone.
