Limb
Dr. Mushfiqul Hoque
Lecturer

2. Topics to be studied
• Anterior Tibial Artery
• Deep Peroneal Nerve
• Superficial Peroneal Nerve
• Dorsalis Pedis Artery
• Superior Extensor Retinaculum
• Inferior Extensor Retinaculum
• Tibial Nerve
• Common Peroneal Nerve
• Posterior Tibial Artery
• Flexor Retinaculum
3. Anterior Tibial Artery
1. Take a point 2.5 cm below the
medial side of the head of the fibula
2. Put another point midway between
the medial and lateral malleoli
Joint these points by a line which passes
downwards and slightly medially
4. Deep Peroneal Nerve
1. Put a point on the lateral side of the
neck of the fibula
2. Put another point midway
between the medial and lateral
malleoli (Same as Anterior tibial
artery)
Join these points by a line which passes
medially in the upper part and is
vertical in the lower part
5. Superficial Peroneal Nerve
1. A point at the lateral aspect of the
neck of the fibula. (same as deep
peroneal nerve)
2. A point at the junction of middle
and lower one-third of the leg, on
the anterior border of the peroneus
longus where the nerve pierces the
deep fascia. The peroneus longus is
made prominent by the eversion
and plantar flexion of the foot.
Join these points by a line
6. Dorsalis Pedis Artery
1. A point midway between the two
malleoli
2. Another point at the proximal end
of the first intermetatarsal space
Join these lines
7. Superior Extensor Retinaculum
1. It is represented by a broad band of
3 cm width from anterior border of
the subcutaneous triangular area of
fibula to the lower part of the
anterior border of the tibia.
8. Tibial Nerve
1. A point at the lower limit of the
popliteal fossa
2. Another point midway between the
medial malleoli and tendo calcaneus
A line joining these points
9. Posterior Tibial Artery
1. A point at the back of the leg at the
level of the neck of the fibula, in line
with the tibial tuberosity
2. A point midway between the medial
malleoli and the tendo-calcaneous
A line joining these points
10. Flexor Retinaculum
It is represented by a band, 2.5 cm
wide, which extends from the medial
malleoli downwards and backwards to
the medial side of the heel.
