From the Research
Yes, the head of the fibula can dislocate, though it's relatively uncommon, as reported in a study from 2019 1. This injury typically occurs from direct trauma to the knee area, a fall, or during sports activities that involve twisting motions. Fibular head dislocations often present with pain on the outside of the knee, swelling, difficulty walking, and sometimes a visible deformity. Some key points to consider about this condition include:
- The dislocation can occur in an anterolateral, posteromedial, or superior direction, as noted in the study from 2019 1.
- Treatment usually involves manual reduction (repositioning) of the dislocated fibula by a healthcare professional, followed by immobilization with a brace or cast for 2 weeks, as seen in the cases presented in the study from 2019 1.
- Physical therapy is typically recommended during recovery to restore strength and range of motion.
- This type of dislocation can be serious because the peroneal nerve runs close to the fibular head, and injury to this nerve can cause numbness, tingling, or weakness in the foot and leg.
- If you suspect a fibular head dislocation, it's essential to seek immediate medical attention to prevent complications and ensure proper healing, as the prognosis is good if the joint is stable after closed reduction, as reported in the study from 2019 1.
Some other studies have reported on the treatment of fibular head dislocations, including the use of surgical techniques such as capsular reconstruction using free autologous gracilis tendon, as described in the study from 2011 2, and the use of suture anchors for fixation of avulsion fractures of the fibular head, as reported in the study from 2018 3. However, the most recent and highest quality study, from 2019 1, provides the most relevant guidance on the treatment of this condition.
It's also worth noting that fibular head dislocations can be associated with other injuries, such as avulsion fractures of the iliotibial band, as reported in the study from 2020 4. Overall, the key to successful treatment of a fibular head dislocation is prompt medical attention and appropriate management to prevent complications and ensure proper healing.
