A clinical study of 147 clavicle fracture patients (one patient had bilateral fractures) who were admitted and treated by the Department of orthopedic surgery of Wonju Christian Hospital, Wonju Medical College, Yon Sei University. The period covered was from September 1974 to August 1981, a total of seven years. The study focused on three fertors in relation to the pain and limitation of motion and these causes were comminution of fracture, shortening of the clavicle length and external deformity. The results were as followings; l. Of the 148 cases, 125 were male and 22 female (one with bilateral fractures). The majority were between 31 and 40 years of age. 2. The mid 1/3 fracture was most common and both sides showed no difference in incidence(left ; 73 cases, right; 75 cases). 3. The mean follow up ranged from 4 months to H3 months with a mean 49.5 months. 4. The complications resulting from comminution, shortening of clavicle length and malunion were shoulder joint pain-16 cases (10.8%), limitation of motion-17 cases(11.5%) and external deformity-18 cases(12.9%). 5. Using a rating scale of excellent(no apparent factors), good( one factor), fair(two factors), poor(more than three factors) the results showed, 106 excellent, 31 good, 9 fair and 2 poor. 6. On a percentage scale, the pain showed difference of 9 times with initial comminution, 7 times with shortening of clavicle length and 7 times with deformity. 8. On a percentage scale, the limitation of motion of shoulder joint showed difference of 6 times with initial comminution, 6 times with shortening of clavicle length and 17 times with deformity.
