Tibia

Contents
Description
The tibia and fibula labeled[1]
- General
- Major weight bearing bone of the lower leg
Proximal
- Tibial plateau forms articular surface, articulates with the femur, to form the Knee Joint along with the patella
- Tibial tuberosity is described below
Mid Shaft
- Interosseus Membrane
- Acts as a fibrous anchor between the tibia and Fibula
- Runs along the length of both bones (lateral side of tibia)
Distal
- Tibial plafond forms articular surface for the Ankle Joint
- Medial malleolus contributes to medial stability
Gerdy's Tubercle
- Bony landmark on superior anterolateral tibia
- Site of attachment of the Iliotibial Tract, Tibialis Anterior
Tibial Tubercle
- Attachment site for Patellar Tendon
- Final component of Knee Extensor Mechanism
Pediatric Considerations
- Proximal Tibial Physis
- Tibial Tubercle Physis
- Apophysis, does not contribute to length of bone
- Attachment site of the patellar tendon
- Appears around age 10 to 12, closes around age 16 to 19[4]
- Developmental Anatomy
- Cartilage stage: occurs before a secondary ossification center appears at the tubercle
- Apophyseal stage: secondary ossification center appears in girls (8-12), boys (9-14)
- Epiphyseal stage: secondary ossification centers (proximal tibia, tubercle) merge into a bony tubercle adjacent to proximal tibial epiphysis
Actions
- Biomechanical
- Supports knee
- Supports knee flexion/extension at the tibial tubercle
- Supports ankle
- Myofascial Compartments
Vascular Supply
Innervation
- Needs to be updated
Clinical Significance
Knee
- All
- Pediatric
- Tibial Tubercle Avulsion Fracture
- Osgood Schlatter Disease
- Patellar Apophysitis (Sinding-Larsen-Johnansson Disease)
- Patellar Pole Avulsion Fracture
Leg
- Adult
- Pediatric
