- Is the smaller of the two bones of the leg.
- Involvement in the transmission of weight is controversial
- Some authors state not directly involved in the transmission of weight.
- Others report it supports 7-16% of body weight during walking
- Is important for ankle stability.
- Acts as a site for numerous muscle attachments.
- Consists of a head, shaft and distal malleolus.
- Head of fibula
- Irregular with a small tubercle called the styloid process.
- Articulates with the tibia to form the superior tibiofibular joint via an articular surface.
- Fibular Neck
- Common peroneal nerve wraps around, posterolaterally to anteromedially, before dividing into superficial and deep branches
- Fibular Shaft
- Three borders and three surfaces.
- Anterior border: runs from the anterior aspect of the head to the triangular shaft proximal to the lateral malleolus.
- Posterior border runs from the styloid process to the medial aspect of the posterior groove of the lateral malleolus.
- Medial border is medial to the anterior border.
- Distal Fibula
- The Lateral malleolus has a triangular facet that articulates with the talus.
- Sixty percent of growth comes from the proximal epiphysis
- This remains open for 18-20 years in males, 16-18 years in females
- Static and dynamic knee stability
- Proximal tibiofibular joint (PTFJ)
- Communicates with the synovial joint space of the knee in 10% of people
- Stabilized by anterior and posterior proximal tibiofibular ligaments, fibular attachment of the LCL, interosseous membrane and distal tibiofemoral joint (DTFJ), surrounding musculature
- Actions: buttress for tibial bending, dissipation of torsional forces applied to the ankle, tensile weight bearing
- Talocrural joint distally.
