Occupational Diseases*

Stroke is a common cause of death in South Korea. The etiology of stroke affects prognosis, outcome, and management. Trials of therapies for patients with acute stroke should include measurement of responses as influenced by the subtypes of stroke. Stroke can be classified into ischemic and hemorrhagic stroke. Ischemic stroke classification denotes five subtypes of ischemic stroke : ① large-artery atheromatous disease, ② cardioembolism, ③ lacunes, ④ stroke of other causes, and ⑤ transient ischemic attack. Hemorrhagic stroke can be classified into ① intracerebral hemorrhage, ② subarachnoid hemorrhage, and ③ other hemorrhages. Stroke is a syndrome with various etiologies, and proper classification is important for the treatment and prognosis. Risk factors for stroke such as hypertension, heart disease, smoking, diabetes, and hypercholesterolemia should be controlled properly. Clinical trials testing new treatment for acute stroke are on-going worldwide, and it is appropriate to standardize the classification of stroke.

Due to rapid industrialization and economic development, the occupational diseases have appeared as one of the social problems in Korea. Up until now little has been known about the prevalence rate, predisposing factor and symptomatology the occupational disease due to localized vibration in Korea. The researcher intends to investigate the prevalence rate and affecting factors of the occupational disease due to localized vibration among rock-drillers in the anthracite mines. A total of 135 rock-drillers were interviewed and examined from May 15th to 31th, 1980. The results were revealed as follows; 1. The prevalence rate of the vibration syndrome among rock-drillers was 12.6%. 2. The latent period of the vibration syndrome was 6.8% years. 3. The prevalence rate of the vibration syndrome was not significantly different between smokers and non-smokers. 4. With the increase of total vibration exposure time, the prevalence rate of the vibration syndrome increased also. 5. The average vibration sensation threshold was high (6.4dB) in stage 1 of the vibration syndrome and low (-0.6dB) in stage 0. 6. The average pain sensation threshold was high (4.4g) in stage 1 of the vibration syndrome and low (2.5g) in stage 0.

Neoplasm Metastasis*

Dislocation of the metacarpophalangeal joint of the finger is rare except thumb. We experienced a case of volar dislocation of little finger and 2 cases of dorsal dislocation of index finger. The mechanism of injury seems to be direct trauma to the dorsum of hand with the metacarpophalangeal joint acutely flexed in volar dislocation and the dorsal dislocation is forced the metacarpophalangeal joint into hyperextension. In 1957, Kaplan advocated the triple incision, that is release of the volar fibrocartilageous plate, the natatory ligament, and the superficial transverse metacarpal ligament, exposing the operation field through a palmar approach. The recommended treatment for such very rare injury is open reduction through nalmar approach in dorsal dislocation, and dorsal approach in volar dislocation; the single most important element preventing reduction is interposition of the volar plate within the joint space in dorsal dislocation and the obstacles of volar dislocation are entraped dorsal capsule and partial ruptured extensor tendon. In dorsal dislocation, we advocated only half release of volar fibrocartilage for lessor trauma of soft tissue and reduction was made easily after release of 1/2 volar fibrocartilage. We report this rare and interesting cases with review of literature.

Stress fractures have been well documented in the lower extremity. Stress fractures of the upper extremities are uncommon. We report a case of an ulna stress fracture in a 32 year old female non-professional golfer.

To determine whether simple curettage is recommendable for the solitary enchondroma of hand, the results of the simple curettage and the curettage with bonegraft were compared in the respects of operation time, the degree of new bone formation, healing time and complications. Thirty five patients have been evaluated to assess the results of treatments. The bone healing and the degree of new bone formation have been evaluated according to the criteria of Tordai (l990). The bone healing had been achieved at average 7.4 months after operation in the simple curettage group and at average 4.6 months in the curettage with bonegraft group (P<0.05). According to Tordai's criteria, among the simple curettage patients, 9 cases (64%) were group I, 5 cases (36%) were group II, no case was group III. Among the curettage with bonegraft patients, 16 cases (76%) were group I, 4 cases (19%) were group II, 1 case (5%) was group III. No significant difference was observed between the two groups in the degree of new bone formation (P=0.05). Although the healing time was longer in the simple curettage group, no significant difference was found in the degree of new bone formation. The pain of the bone donor site was absent in the simple curettage group, and the simple curettage can reduce the operation time. The curettage alone is a recommendable treatment for solitary enchondroma in hand.

After reconstruction of anterior cruciate ligament, increased idameter of femoral or tibia1 bone tunnel has been obsened on plain radiogram. The etiology of radiographic tunnel enlargement is not well understood and the significance of this tunnel enlargement is unknown. This retrospective study reviewed tibial tunnel diameter in 34 cases of anterior cruciate ligament reconstructions. And we evaluated the correlation between the tibial tunnel enlargement and the position of screw fixation, instability, choice of graft, and clinical results at 1 year postoperatively. AII operation was per formed using a single incision technique. After 3 or 4 months and one year after operation, the diameter of tibial tunnel was measured with digital caliper on the plain radiogram. Tibial tunnel sclerotic margins were measured in the level Of medial tibial plateau on the lateral view of knee. Average tunnel enlargement of 3 allografts was 1.62mm and that of 15 autografts was 2.03mm. No significant difference was seen in KT-10000 arthrometer measurements between enlarged group (amount of enlage-ent >+1 S.D) and not-enlarged group (less than +1 S.D). No coelation was present between the increased tunnel diameter and Lysholm score. Cases with 10mm or more vertical distance between the most proximal point of tihial interference screw and the level of m4eial tibial plateau had average 1.15mm tibial tunnel enlargement and cases with less than 10mm vertical distance ha & I average 2.52mm tibial tunne] enlargement;the difference was not significant (P>0.05). The tibial tunnel enlargement was not correlated with position of screw, clinical results, stability of knee. The tibial tunnel enlargement was not caused hy only mechanical factor such as motion of intra-tunnel portion of graft-tendon.
