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.

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.

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 evaluate the intra-articular pathology of popliteal cysts of knee, we performed arthroscopy on patients with popliteal cysts between February 1992 and February 1995. Thirty-one patients (32 cases) have been treated by excision of cyst after arthroscopy. Mean duration of follow-up was 15 months (13-19 months). Location of cysts was in the right knee in 17 cases, in the left knee in 13 cases, and bilateral in one case. Pain or swelling was present in 12 (38%), giving-way was reported by 4 cases. Three cases revealed quadryceps atrophy. The McMurray test was postive in 6 cases. After arthroscopy, the cysts were excised. Ninteen cases (59%) had associated intra-articular lesions: seven medial meniscal tears, two lateral meniscal tears, seven had chondral damages, one had medial plica syndrome, and one had rheumatoid arthritis, Communication between the cyst and the knee was present in 7 cases (22%), all of whom were over 40 years of age. Thirteen cases was younger than 30 years of age, and 11 cases of these cases had no intra-articular pathology. Two other cases had lateral meniscal tears and medial plica syndrome, respectively. We recommend arthroscopy in middle and older aged patients with popliteal cysts for evaluating and treating intra-articular lesions.

Fractures of the shaft of the humerus due to muscle violence esp. from throwing hand grenades are uncommon. Even so there are reports from many authors documenting such fractures from throwing a javerin, baseball, hand grenade and arm wrestling. Fractures of this type are usually spiral in nature; located between the middle and distal third of the humerus. We have treated four such cases during activities in which hand grenades were thrown. These fractures were sustained by military recruits in the Department of Orthopaedic Surgery, Capital Armed Forces General Hospital from Jan. 1980 Dec. 1980.
