Background:
Post-traumatic elbow contractures in children and adolescents are
challenging to manage, and studies investigating surgical treatment are
limited by the rarity of this condition. Small case series have shown
variable gains in immediate and long-term elbow arc of motion after open
surgical release. We reviewed our experience with open surgical release of
post-traumatic elbow contracture in patients less than 21 years old at two
institutions.
Methods:
A retrospective chart review identified patients who underwent
post-traumatic open elbow contracture release by two surgeons at two
institutions between 2006 and 2013. Non-traumatic contractures and
arthroscopic releases were excluded. 26 patients were included in this
study. Mean age at the time of injury was 12 years (5–19 years) and
at the time of surgery was 14 years (7–20 years). Capsulotomy,
osteoplasty, removal of hardware, ulnar nerve release or transposition, and
ligament reconstruction were performed through medial and lateral approaches
as indicated by the pathology. 10 patients had ligament repair or
stabilization, and 16 patients used a CPM post-operatively. Outcomes
included active range of motion and complications.
Results:
Mean time from injury to surgical release was 29 months. Mean
post-operative follow-up was 42 months. Elbow active flexion-extension and
forearm rotation arcs both increased significantly by a mean of 49°
and 70°, respectively, at final follow-up. A mean 85% of
intra-operative flexion-extension arc was maintained at final follow-up.
Ligament repair or reconstruction and the use of a postoperative CPM did not
significantly change these outcomes. Outcomes were not significantly
different if our contracture release was performed within a year from
injury. Patients who had surgery prior to our contracture release had
decreased restoration of forearm rotation after release. Complications
included two recurrent contractures (one used a CPM and one did not), and
two post-operative ulnar neuropathies (one used a CPM and one did not).
Conclusions:
Open contracture release for post-traumatic elbow contracture in an
adolescent population can significantly improve active range of motion.
