CROSSED LATERAL ASCENDING AND DESCENDING PINNING IN PEDIATRIC SUPRACONDYLAR FRACTURE OF HUMERUS

Abstract

Background: Extra-articular supracondylar fracture of the humerus is 3% in children and 60% in all
elbow fractures. The highest incidence of ligament laxity and the weakening of distal humerus at this
era are at present in the first decade of existence. The aim of the present study was to assess the results
of cross lateral ascending and descending pinning in pediatric supracondylar fractures humerus.
Patients and methods: This study consisted of 18 children with supracondylar humerous fractures
who underwent lateral pinning in the Zagazig University, and Ibnsina hospitals. Results: The age of
the studied group was (6.6±2.1) years ranged from 6 to 10 years, half of the group (50 %) had aged less
than 6.5 years and (50%) from 6.5 to 11 years. More than half of the studied group (61.1%) were males
and (38.9%) of them were females. Regarding side affected, 55.6%) of the studied group were right
sided affected and (44.4%) of them were left sided. The commonest mechanism of injury was FD
among (83.3%) of the studied group followed by RTA was among (16.7%) of the studied group.
Regarding displacement, postero-medial was the commonest displacement among (61.1%) of the
studied group followed by postero-lateral was among (22.2%) of the studied group and lastly posterior
one (16.7%). More than half of the studied group (55.6%) had excellent cosmetic score, (27.7%) of
them had good cosmetic score and (11.1%& 5.6%) had fair and poor cosmetic score respectively. More
than half of the studied group (55.6%) had excellent functional outcome, (27.7%) of them had good
functional outcome and (11.1%& 5.6%) had fair and poor functional outcome respectively.
Conclusion: Possibly the best mechanical stability is provided by a cross pin fixation. The lateral
cross-pinning technique has been found to be excellent for stability with crossed pins and to prevent
damage to the ulnar nerve.
