Therefore, this is also a longitudinal split tear of the brevis with an accessory muscle and a bony spur, which may also be a cartilaginous spur. This spur would be removed in surgery. Treatment for longitudinal split tears starts off conservatively with orthotics, bracing, and decreased activity. Repair can, however, be eventuated. The lateral collateral ligaments also need to be shored up.
Surgeons can easily resect the brevis.
Resection does not leave the patients with any deficit, and it ceases their pain. Surgeons also will remove the lateral bony spur if present, and they will decompress the peroneal tunnel if there is an accessory muscle or tendon there. However, before surgery can be effectively done, the ailment must be diagnosed. Longitudinal split tears are not easily diagnosed, because they can mimic many chronic lateral ankle problems. The flexor hallucis longus is not commonly involved with pathology.
