A Flexor Carpi Radialis Brevis Muscle With an Anomalous Origin on the Distal Radius

Background: Volar locking plates were increasing popular as treatment of distal radius fractures. Various distal forearm anatomical variants were encountered during surgery. Flexor carpi radialis brevis (FCRB) was one of the most common and relevant anatomical variants because of its close proximity to fracture site. Methods: This is a retrospective single-centre study. In a 3.5-year period from March 2015 to August 2018, 133 patients who suffered from distal radius fracture requiring volar wrist plating were identified. Operation records and clinical photos were reviewed. All patients were followed up for at least 1 year. Any complications were recorded. Results: 9 patients with FCRB variant were identified. The prevalence was 6.8%. Hypoplastic pronator quadratus were found in 5 cases out of the 9 cases. None of these cases had any neurovascular injuries. No complications were noted during follow-up at 1 year. Conclusions: In Chinese population with volar locking plate done for distal radius fracture, the prevalence of flexor carpi radialis brevis was 6.8%. Surgeons should be aware of the possibility of FCRB variant.

Clinical Series

An anomalous presentation of flexor carpi radialis brevis (FCRB) is reported in six patients. These findings occurred in a consecutive series of 172 distal radius fracture fixations using a volar approach between 2002 and 2007. This is the first report of this anomalous muscle from a clinical series.

Minimal Invasive Approach

This article reviews the author’s currently used minimal invasive approach for volar plating of distal radius fractures. A single longitudinal incision of 1.5 cm is drawn on the lateral aspect of the flexor carpi radialis tendon in order to insert a plate under the pronator quadratus. With the wrist flexed, the plate is applied on the anterior cortex of the radius to reduce the fracture. This approach offers the advantage of preserving ligamentotaxis, which facilitates the reduction, and the small scar improves the cosmetics. It is mainly indicated for extra-articular and simple intra-articular fractures of the distal radius. Relative contraindications are comminuted articular fractures in elderly osteoporotic patients. Functional and radiological results are comparable with those obtained with an extended flexor carpi radialis approach. My colleagues and I have used it for more than 2000 cases since 2012. This technique requires practise. Attempted conversion to a larger incision is possible in case of difficulty, but this is seldom necessary.
