Hypertroof peroneaal tuberculum met tenosynovitis van de peroneuspezen

Hypertrophy of the peroneal tubercle: a rare cause of peroneal tendon synovitis Hypertrophy of the peroneal tubercle is a rare cause of peroneal tendon synovitis. The peroneal tubercle of the calcaneal bone is an anatomical structure with both structural and biomechanical functions. When abnormal in shape and size, it can cause friction or impingement of the peroneal tendons, resulting in tenosynovitis and/or tendon tears. Clinically, the patient presents with tenosynovitis and a prominent peroneal tubercle palpable on the lateral calcaneus. A radiography and an ultrasound are sufficient for the diagnosis. An additional CT scan and MRI are often performed to better visualize the bony structures and soft tissues, respectively. The treatment consists of conservative therapy for at least 6 weeks. If this therapy fails or if the tendon is torn, surgery may be required.
