PurposeDorsal plating of distal radius fractures with traditional 2.5-mm-thick plates is associated with extensor tendon complications. Consequently, volar locking plates have gained widespread acceptance. A new generation of 1.2- to 1.5-mm, low-profile dorsal plates was designed to minimize tendon irritation. This study examines the complication rates of low-profile dorsal plates compared with volar locking plates.MethodsWe identified patients with distal radius fractures treated between September 2002 and June 2006 by low-profile dorsal or volar locking plates. Information pertaining to 7 categories of complications (hardware discomfort and pain, tendon irritation/rupture, failure of reduction, infection, complex regional pain syndrome, stiffness, and neuropathy/hypersensitivity) was collected. Complications were defined as any postoperative plating complications requiring additional surgical intervention, whereas those that only caused patient discomfort were considered secondary problems.ResultsWe included 100 patients, comprising 104 plating cases (57 dorsal, 47 volar), in this study. Overall length of follow-up was 44 ± 21 months (range, 12-80 mo). A total of 18 patients (8 dorsal, 10 volar) experienced complications, whereas 47 (25 dorsal, 22 volar) had secondary reports. Three dorsal and 4 volar patients had complete plate removals. Three dorsal and no volar plates had screw removals only. One volar plate (no dorsal plates) had a major tendon rupture (flexor pollicis longus); 3 dorsal and 3 volar plates resulted in tendon irritation complications, and 4 dorsal and 3 volar plates had secondary problems from tendon irritation. None of the above measures approached statistical significance. Volar cases were associated with significantly more neuropathic complications than dorsal cases.ConclusionsDorsal low-profile plates are not associated with significantly more tendon irritation or rupture complications. However, volar plating is associated with a higher rate of neuropathic complications.Type Of Study/Level Of EvidenceTherapeutic III.Copyright © 2011 American Society for Surgery of the Hand.
