Orthogonal and parallel plating methods: equivalent for distal humerus fracture treatment .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(16):51 Eur J Orthop Surg Traumatol. 2013 Aug 7.72 patients with Type C distal humerus fractures were included in this trial and scheduled for treatment using a double-plating surgery. Patients were then randomized to two different plating groups to compare an orthogonal pattern with a locking compression distal humerus plate and a parallel plating pattern. Both plating methods utilized anatomically precontoured plates. At final follow-up there were no non-unions observed in either group. Pain, functional outcomes, complications and heterotrophic ossification rates were similar between the two groups. The results of this study did not identify any advantage of one plating method over another.

The Fragility Index is a tool that aids in the interpretation of significant findings, providing a measure of strength for a result. The Fragility Index represents the number of consecutive events that need to be added to a dichotomous outcome to make the finding no longer significant. A small number represents a weaker finding and a large number represents a stronger finding.
Why was this study needed now?
Distal humeral fractures can be treated in a number of different ways. Previous investigations have demonstrated that double plate fixation provides adequate stability. Typically this treatment involves two plates placed perpendicular to each other to secure the fractured bone; however stable fixation can also be achieved with a parallel plating method. Currently there is a lack of clinical trials comparing outcomes between orthogonal and parallel plating methods using preconditioned distal humerus plates. This study was required to compare theses differing surgical plating option for the treatment of distal humeral fractures.
What was the principal research question?
Does a parallel plating method yield higher success in clinical and radiological outcomes than the standard orthogonal plating method for operating on distal humeral fractures?
- Complications such as ulnar neuropathy, metal failure, and infection occurred regardless of which plating method was used (p>0.05).
- 8 patients in the orthogonal plating group and 13 patients in the parallel plating group needed hardware removal (mean removal date 1.8 +/- 0.6 years after surgery).
- No nonunions were found in any patients (p=1.00).
- Operation time (p=0.68) and the time it took for bony union to form were very similar in both groups (p=0.62).
- There were no differences found in final clinical outcomes including MEPS, DASH, VAS, or elbow ROM scores (p>0.05).
- Heterotrophic ossification occurred in 3 orthogonal plating patients and 2 parallel plating patients (p=0.55).
What should I remember most?
Double-plating surgery with precontoured anatomical plates is equally effective when using orthogonal or parallel plating methods based on clinical and radiographic outcomes measured every 3 months for over 2 years.
How will this affect the care of my patients?
Patients treated for Type C distal humerus fractures undergoing double-plate fixation surgery experienced the same clinical and radiographic outcomes regardless of the plating method used. Further research is required to determine the functional outcomes associated with each method and to examine different plating methods to treat specific fracture patterns.
