1. From 1959 through 1963, 97 patients were seen at our hospital because of elbow fracture and/or dislocation. Seventy (72 percent) of these were seen at follow-up.
The age of patients ranged from 1 to 15 years. Male left elbow are predisposed. Most common causes are a fall from bicycle (10 cases), from tree (10 cases), during gymnastic on the bar (16 cases) and fall down while playing (15 cases).
2. Seventy patients are as follows:
There are 31 fresh (15 closed treat. & 16op. treat.) & one old op. treated supracondylar fr., 14 fresh (7 closed treat. & 7op. treat.) and 4 old (2 closed treat. & 2op. treat.) lat. cond, fr., 4 fresh (3 closed treat. & 1op. treat.) and 2 old closed treated med. cond. fr., 3 fresh (2 closed treat. & 1op. treat.) & 2 old op. treated dislocation and/or fr. and 9 fresh (6 closed treat. & 3 op, treat.) other type of fractures.
(Fresh: treated with in 2 weeks after injury. Old: treated after 2 weeks after inyury.)
3. one to seven years follow-up after injury are as follows:
(1) In five of thirty two patients of supracondylar fracture and two of eighteen patients of lateral condylar fracture the range of flexion motion were not complete with restriction ranged from 60 to 90 degrees.
(2) The incidence of changes in carrying-angle after supracondylar fracture are 58 per cent. Of thirty-one patients (fresh fracture), sixteen (52 per cent) showed decreasing in carrying-angle. of these sixteen patients, seven (23 percent) were enough to be called Gunstock deformities (8 to 27 degrees). Of thirty-one patients, two (6 per cent) showed increasing (5 degrees) in carrying angel. The incidence of that changes after lateral condylar fracture are 50 percent. of fourteen patients (fresh fracture), four (28 percent) showed decreasing in carrying-angle. Of these four patients, two (14 per cent) showed Gunstock deformities (6 to 27 degrees). Of fourteen patients, three (21 per cent) increased in carrying-angle (5 to 12 degrees).
Such a changes, decreasing and increasing, in carrying-angle after the other type of fractures were noted one patient respectively.
(3) The elongation of condylar line with enlarged lower end of humerus ranged from 2 to 10 milimeters with the average of 4 milimeters.
(4) Two of eighteen. patients of the lateral condylar fracture and two of eighteen patients of the medial condylar fracture were showed non-union respectively.
(5) Only one patient of supracondylar fracture had nerve damage; This patient showed signs of claw hand on admission. Recovery had not occurred when he was seen for follow up one year later. The other one patient of supracondylar fracture was noted miositis ossificans with restriction of motion.
