Abstract
Background:
Peroneal tendon subluxation is a rare condition that often misdiagnosed, generally associated with sport related injury. Subluxation of the peroneal tendons is uncommon and is frequently misinterpreted as an ankle sprain, usually in young and active patients. The most common pathological mechanism is a dorsiflexory and mostly caused by avulsion of the superior peroneal retinaculum (SPR) from its fibular insertion. Treatment may be conservative or surgical, although there is no agreement on the best technique to use.
Case Report:
A 35-year-old man presented with pain and swelling of the lateral side of the left foot after play badminton. The patient felt pain upon palpation and snapping sign during flexion–extension of the left ankle. The patient was treated with conservative treatment for 1 month with no improvement, and we recommended to do surgical treatment for relieved the pain.
Discussion:
Superior Peroneal Retinaculum Reconstruction shows an great result; after the procedure, there are no significant side effects such infections, wound issues, or ongoing discomfort. The surgical outcome was viewed as satisfactory overall. Following surgery, the ankle was put in a semi-equinus position for two weeks while being immobilized with a non-weight-bearing, temporary below-knee cast.
Conclusion:
Acute peroneus longus subluxation might be difficult to diagnose since it is usually misinterpreted as an ankle sprain. The occurrence of peroneal tendon subluxation is rather low, and surgery is the main treatment for this injury. If conservative treatment shows no improvement, variety of surgical techniques are available. Several literature reported superior peroneal retinaculum reconstruction has satisfactory outcome.
