Term
Proximal end
Definition

·      Expanded relative to shaft

o   Posterolateral part: gives rise to bony process that projects SUP (Apex or Styloid process of Fibula)

Term
Articular Facet of the Head of Fibula
Definition

 

 

 

 

Superomedial part has facet that articulates w/ Fibular Facet of LAT Condyle of Tibia at Proximal Tibiofibular joint (Synovial; plane type)

Term
Apex of the Head
Definition

·      Bony process on Posterolateral part of proximal end 

Term
Fibular Neck
Definition

·      Common Fibular Nerve passes immediately LAT to neck; fractures can cause ruptures leading to Foot Drop

Term
Medial Anteromedial Surface
Definition

o   located between anterior and interosseous borders à narrowest surface of fibular shaft à gives origin to muscles of anterior compartment of leg

Term
Lateral Fibular Surface
Definition

located between anterior and posterior borders à gives origin to muscles of lateral compartment of leg

Term
Posterior Fibular Surface
Definition

located between posterior and interosseous borders à largest surface of fibular shaft à SUP divided by vertical bony ridge (medial crest) 

Term
Medial Crest of Fibula
Definition

·      Vertical bony ridge on POST surface and seperates into 2 parts (posteromedial and posterolateral) à both parts give origin to muscles of posterior compartment of leg

Term
Nutrient Foreamen of Fibula
Definition

·      for nutrient artery of fibular shaft) is located on posterior surface, usually in its posterolateral part (directed distally)

Term
Lateral Malleolus
Definition

More POST and projects more Distally than Medial malleolus; Lateral surface palpable and subcutaneous

Term
Articular facet of the Lateral Malleolus
Definition

On MED surface of Lateral Malleolus; containts triangular facet for articulation with lateral surface of Body of Talus at ankle joint.

Term
Malleolar Fossa of Fibula
Definition

Depression on MED surface of LAT malleolus; POST to articular facet; gives attachment to Posterior Tibiofibular ligament of distal tibiofibular joint and to Posterior Talofibular ligament of ankle joint

Term
Malleolar Groove of Fibula
Definition

Shallow groove on POST border of LAT Malleolous formed by Tendon of Fibularis Brevis muscle
