3. Aponeurosis
A flat/thin sheet of connective
tissue in your body.
It help connect muscles to bone.
Important for Movement and
posture.
You have Aponeurosis all over
your body.
7. Palmar Aponeurosis:
The central part of the
deep fascia of the palm.
Highly specialized
thickened structure with
little mobility.
Triangular in shape in
centre of Palm.

9. Continue,,,
It covers underlying
neurovascular and tendon
structures.
It considered as degenerated
tendon of Palmaris Longus.
Fuses medially and laterally with
deep fascia.
10.
11. Function:
• Gives firm attachment
to the skin of palm to
improve grip.
• Protect Underlying
tendons, vessels
&nerves.
12. Mainly it covers:
Superficial Palmar Arch.
Long flexor Tendon.
Terminal part of median nerve.
Superficially ulnar nerve.
Hypothenar & Thenar muscles.
13.
14. Apex:
Lies proximally & blends with flexor
retinaculum.
Continuous with tendon of Palmaris
Longus.
15. Base:
Base is from distal border of
flexor retinaculum.
Rise out distally towards fingers.
Base is further divided into
Superficial & deep strata.
17. Deep strata
Again divided into four slips (one for
each finger) .
Slips opposite the heads of
Metacarpals of medial four digits.
18. Clinical relevance:
Thickening and contraction
due to inflammation of ulnar
side of aponeurosis leads to
DUPUYTREN’s
CONTRACTURE.
19.
20.
21. Dupuytren’s contracture:
A benign, progressive disease of
Palmar fascia/ Palmar
Aponeurosis.
It results in thickening, shortening,
and fibrosis of the fascia and
Aponeurosis of palm.
22.
23. Continue,,
Dupuytren’s disease affects
hands/fingers and result in contracture
deformities.
Commonly afected digits are fourth &
fifth digits.
Disease begins with cords & nodules.
