Systematic review: dorsal bridge plating in distal radius fractures.

Purpose: Distal radius fractures are the most common upper limb fractures in adults (up to 18% of all fractures in the Emergency Department). Conservative management is possible for the majority, the preferred surgical technique being volar plate fixation. Dorsal bridge plating (DBP) is an alternative method of treatment for complex fractures. DBP acts as an internal fixator and can be used in patients needing early rehabilitation. This systematic review assesses the demographics, functional and radiological outcomes and complications of using DBP in patients with distal radius fractures compared to volar plate fixation.

Methods: A literature search of PubMed, Cochrane, EMBASE and Google Scholar was performed according to PRISMA guidelines. Seven hundred and sixty-one articles were found; 11 articles met the inclusion criteria. Cadaveric studies and case studies of less than five patients were excluded. Primary outcome measures were functional and radiological outcomes. Complications were recorded as secondary outcomes.

Results: Three hundred and ninety-four patients were included in the study with an average age of 54.8 years (53.9% male and 46.1% female). Weighted mean follow-up was 55.2 weeks; the mean time to plate removal was 17.3 weeks with a mean DASH score of 25.7. The weighted range of movement was 46.9° flexion, 48.8° extension, 68.4° pronation and 67.5° supination. The radiological parameters show satisfactory outcomes with a mean radial height of 10mm, volar tilt of 3.1°, ulnar variance of 0.5mm and radial inclination of 18.8°. The complication rate was 11.4%. Digital stiffness was the most common complication but improved if tenolysis was performed at plate removal.

Conclusions: DBP is a good alternative to volar plating for complex distal radius fractures. The functional outcomes showed a slight loss of range of movement, whereas the radiological outcomes were within recommended limits. A significant disadvantage of the plate is the need for further surgical removal.
