Case Description:
A 25 years old man presented with a laceration on radial side of proximal phalanx of 4(th) finger (zone II flexor) which was due to cut with glass.
Clinical Findings:
The sheaths of Tendons of flexor digitorum superficialis and profundus were not the same and each tendon had a separate sheath.

The tendons were reconstructed by modified Kessler sutures, after 15 months the patient had a 30 degrees of extension lag even after physiotherapy courses.
Clinical Relevance:
This is the first reported of such normal variation in human hand tendon anatomy.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
