- Percutaneous Pin Fixation
- Type III Supracondylar Frx
- vascular injuries
- inadequate reduction;
- brachialis may become interposed at frx site or by proximal humeral frx fragment button-holed thru brachialis (see physical exam);
- if this occurs, closed reduction w/ longitudinal traction may worsen tightening of the muscle around protruding fragment;
- tears proximal to frx site, and may become interposed into anterior frx gap;
- w/ interposed periosteum open reduction is required;
- Surgical Approach for Inadequate Reduction:
- consider the standard posterior approach;
- alternatively limited medial and lateral incisions allow direct access to the entire surface of the fracture and should guarantee protection for the nerve;
- Surgical Approach for Vascular Injury:
- begin w/ transverse incision over antecubital fossa, and subsequently decide if further exposure is needed on the proximal-medial side vs. the distal-lateral side;
- posterolateral displacement:
- need to visualize the medial spike of the proximal fragment and to explore the median nerve and brachial artery;
- consider anteromedial approach;
- posteromedial displacement:
- need to visualize the lateral spike of the proximal fragment and radial nerve;
- consider anterolateral approach:
- w/ either approach, reduction requires hyperflexion, which precludes adequate visualization of frx site;
- attempt to palpate frx reduction as elbow is hyperflexed;
- following frx reduction, insert crossed pins thru stab incisions; (cross pinning technique);
- Case Example:
- 3-year-old child who sustained a type III supracondylar fracture following a fall;
- on physical exam there was subcutaneous ecchymosis (bone has buttonholed thru brachialis);
- an attempt was made at closed reduction and pinning, but this resulted in marked decrease in pulse;
- an open reduction was subsequently performed and the brachial artery was noted to be partially entrapped at the fracture site;
- Case Example:
- 7-year-old female who presented with a displaced supracondylar fracture - an attempt at closed reduction was carried out, but the reduction was unacceptable;
- open reduction was carried out via limited medial and lateral incisions;
