![]() The same general principles as listed above should be applied. ![]() Type of fracture line - transverse, oblique, spiral, comminuted, segmental. We utilized a simple modification that allowed for closed reduction and percutaneous pinning of displaced RO fractures. Proximal humerus fractures often occur in older patients after a low-energy fall. Further, traditional reduction methods proved to be ineffectual for this fracture pattern. We found increased rates of soft tissue compromise including antecubital ecchymosis and AIN palsy in this fracture type. This study introduces a previously undescribed supracondylar humerus fracture subtype: the RO fracture. Compared with non-RO type III fractures, RO type III fractures had higher rates of AIN injury (P=0.047), antecubital ecchymosis (P=0.007), and overall soft tissue injury (P=0.009). When comparing RO with non-RO type II fractures, there were no differences in soft tissue injury (P=0.439). Compared with non-RO fractures, the RO fracture group had significantly higher rates of anterior interosseous nerve (AIN) palsies (P=0.013), antecubital ecchymosis (P=0.018), and compartment syndrome (P=0.043). Overall cohort rates of preoperative soft tissue injury included antecubital ecchymosis 16.8%, nerve palsies 15%, and vascular compromise 6.4%. All displaced RO fractures were able to be closed reduced with a modification to the traditional reduction sequence. The RO fracture pattern was seen in 12 patients. Two hundred ninety-nine consecutive patients were reviewed. Associated neurovascular injuries were compared between groups. Patients were categorized into RO and non-RO groups for analysis. Retrospective evaluation of operative supracondylar humerus fractures treated at a tertiary pediatric hospital from 2014 to 2016. We hypothesized that the RO pattern would be associated with greater soft tissue trauma. The purpose of this study is to compare the clinical and radiographic characteristics of the RO and non-RO patterns of supracondylar humerus fractures. C, A long oblique fracture of the midshaft of the humerus repaired with an intramedullary pin and cerclage wires. 37,42,63,68 Diaphyseal humeral fractures are caused by road traffic accidents. This pattern presents a challenge during closed manipulation utilizing traditional reduction maneuvers. Humeral fractures account for 8 to 10 of fractures in dogs and 5 to 13 of fractures in cats. We describe a reverse oblique (RO) pattern in which the distal fragment has a prominent anterior spike that is displaced posterior to the proximal fragment. Sagittal profile descriptions of supracondylar humerus fractures are limited.
