FIGURE 1: The wrist crease and hand lie at the top of the photograph, ulnar on the left, and radial on the right. The proximal (1) and distal (2) ends of the divided FCR tendons are being retracted ulnarward. The intact radial artery (3) lies immediately radial to the supernumerary FCRB muscle (4). The FCRB presented as a fleshy muscle at the wrist, with an oblique shelving laceration, and it is labeled at the laceration midpoint.  
FIGURE 2: The orientation is the same as that of Figure 1. The distal (1) and proximal (3) ends of the supernumerary FCUB are demonstrated, being retracted radially by the forceps. The FCU tendon (2) lies ulnar to the anomalous muscle, and it is being retracted by a tendon hook. The proximal end of the FPL tendon (4) is shown. Multiple divided flexor tendons to the digits are shown in an exploratory carpal tunnel release (5).
FIGURE 4: A T1-weighted MRI of the non-operated (left) forearm, coronal slice. Again, the FCRB is seen crossing the radial wrist as a fleshy fusiform muscle with a central tendon. The FPL tendon is seen more distally, and it appears distinct to that of FCRB. Unlike the contralateral forearm, there is no supernumerary muscle belly crossing the ulnar wrist.  
FIGURE 5: Sagittal slice. The FCRB has a broad, longitudinal origin from the volar half of the radius. The muscle belly lies deep to the FCR tendon. The 2 tendons cross the wrist and are seen passing together toward the base of the second meta- carpal.

We present findings of anomalous musculotendinous anatomy in a patient having exploration of an acute volar wrist laceration. Surgical dissection demonstrated supernumerary flexor carpi radialis brevis and flexor carpi ulnaris brevis muscle bellies crossing the radiocarpal and ulnocarpal joints, in addition to injuries to several normal tendons and nerves. Postoperative magnetic resonance imaging confirmed the presence of a bilateral supernumerary flexor carpi radialis brevis but contralateral absence of flexor carpi ulnaris brevis.

... Among cases of FCRB specifically, many FCR tendons insert normally onto the second and third metacarpal. However, the FCRB often inserts into the FCR tendon sheath, running parallel with the FCR tendon and creating an anomalous shared insertion onto the second metacarpal base [9][10][11]. The FCR tendon serves as an important anatomical landmark in several procedures performed on the volar aspect of the distal upper extremity [12]. ...
