Acute calcific tendinitis of the peroneus longus tendon

Painful lateral foot swelling

“…Early recognition and supportive therapy including NSAIDs, elevation, non-weight bearing, ice, and rest are appropriate first line treatments. If symptoms do not improve with supportive therapy, ultrasound-guided needle lavage, corticosteroid injection and surgical debridement may offer clinical improvement [4][5][6]; however, with appropriate diagnosis, management, and time, the majority of cases will resolve without surgical intervention.…”

“…The incidence of peroneus longus calcific tendonitis is uncommon with few cases reported in the literature [3][4][5][7][8][9]. Patients typically present with acute onset unilateral foot pain with swelling.…”

“…Patients typically present with acute onset unilateral foot pain with swelling. Full range of motion in the ankle, sub-talar, and midfoot joints are preserved [4,5,7]. Mild tenderness to palpation in the lateral aspect of the foot proximal to the base of the fifth metatarsal has been described [5,7].…”

“…Full range of motion in the ankle, sub-talar, and midfoot joints are preserved [4,5,7]. Mild tenderness to palpation in the lateral aspect of the foot proximal to the base of the fifth metatarsal has been described [5,7]. Patients have no history of trauma to the area but often have a history of working on their feet such as standing on a ladder for extended periods of time, ballroom dancing, and wearing high-heeled shoes [4,7].…”

“…Patients have no history of trauma to the area but often have a history of working on their feet such as standing on a ladder for extended periods of time, ballroom dancing, and wearing high-heeled shoes [4,7]. Laboratory examination can reveal mildly elevated ESR, CRP, and leukocytosis [5,7]. Radiographic examination demonstrates calcifications within the peroneus longus tendon unilaterally.…”
