“…Ho [16]. In vivo cases are usually asymptomatic, accidental findings but tenosynovitis of this muscle may present as a painful forearm swelling [17,18]. In the present study, origin was from anterior oblique line of radius deep to pronator teres and lower attachment was to flexor retinaculum lateral to FCR.…”

Introduction: Muscular variations in the form of accessory muscles are common and observed during cadaveric dissections, surgeries or investigative radiological procedures. Knowledge of such variations in upper limb is useful for hand surgeons and neurosurgeons. Materials and Methods: Total 156 (80 of right side and 76 of left side) upper limbs of unknown sex were dissected for presence of accessory muscles in the flexor compartment of the forearm. Observed accessory bellies and anatomical variant muscles were studied for its origin and insertion, size and shape and its important relations. Observations: Accessory head for the flexor pollicis longus (ahFPL) was the most common variation found in 56 (36%) limbs. Accessory head for the flexor digitorum profundus (ahFDP) was observed in five (3.2%) limbs, and accessory head for the flexor digitorum superficialis (ahFDS) in two limbs (1.2%,). Two accessory bellies in the same hand with common or separate origin were found in 5 limbs (3.2%). An anatomical variant flexor carpi radialis brevis (FCRB), which is not very common, was found in one limb. Conclusion: Accessory bellies of the muscles in the forearm are known for compression neuropathies like anterior interosseous nerve syndrome (AINS). Available accessory muscles like FCRB could be used for tendon transfers in patients with arthritis of thumb. Awareness of such variations helps in diagnosis of neuropathies, to avoid complications during surgeries and most importantly accessory muscles could be used for tendon graft/ transfer to to transform disability into functional hands.

“…1-2 An FCRB that is associated with pain is extremely rare; we found only one report in the literature. 5 We report another case with the same clinical presentation. The etiology of the pain appeared to be due to the separate compartment for the FCRB and accompanying tenosynovitis.…”

“…3,4 The FCRB tendon usually passes beneath the FCR tendon and has various sites of insertion, such as the second, third or forth metacarpal, trapezium, and capitate. [1][2][3][4][5] The FCR and FCRB tendons were found in the same compartment in all studies. [1][2][3][4][5] To our knowledge, the separate compartment in our case has not been reported previously.…”

“…Hence, the initial muscular portion was only present in the superficial aspect and the FCR on its entire length was ten dinous in its deep aspect. There are various reports stating the existence of FCR brevis [2][3][4][5][6] , but there were no reports of tendinous FCR reported so far based on our literature search, which makes this variant case of FCR the first to be reported.…”
