Abstract
’ ’ ’
The goals of management of a displaced supracondylar fracture are to recover
full function in a cosmetically normal elbow and avoidance of complication. The commonly accepted
treatment in children is fracture reduction and percutaneous pin fixation.
In this work we studied the results of treatment of displaced extension type
supracondylar fractures of the humerus in children by closed reduction and percutaneous
fixation by K-wires
Twenty children were treated by this method. All of them were grade 3 according to
Wilkin’s modification of Gartland classification.
The cases were examined clinically and radiologically at first. and ten cases were
operated in the same day and 10 cases were delayed because of severe oedema. Under general
anesthesia ,with fluoroscopic control, the fracture was reduced and two K-wires were used to fix
the fracture percutaneously. then the arm was immobilized in posterior slab for 3 weeks
After removal of the slab the patients were left to do exercises till full range of movement was
achieved
The results were assessed both functionally and cosmetically according to criteria described by
Flynn et al1974.
The overall results obtained were satisfactory in 95% of cases (19 case) and unsatisfactory in 5 %
of cases ( one case) and that was in the case which was
treated by two lateral wires because of pin migration .
Very important factors were studied in relation to the results and revealed that:
Early treatment of the patients make the reduction easy and gives good results
Management Of edema in the form of anti-edema drugs and elevation of the limb make the reduction
easy and allow palpation of the ulnar nerve during insertion of the medial pin.
In our study, only one of the cases treated with 2 lateral pms (5%) developed pin migration which
led to some loss of reduction. The cause was that the distance between the 2 pins was not wide
enough and that pin did not engage the far cortex. This was not severe enough to necessitate any
secondary operative procedure.
