Picture 1: Flexor tendon tunnel in the finger and complex intertwining of the superficial and deep flexor tendons in the hand

Picture 2: Malet Deformity - inability to straighten the distal most part of the finger due to extensor tendon injury

Picture 3: Hyperextension splints commonly used to treat Malet deformity

Picture 4: Flexor tendon Injury - inability to bend finger fully and make a proper fist

Picture 5: Fracture commonly associated with a deep flexor tendon avulsion injury also known as "Jersey finger"

Picture 6: Retraction of flexor tendon after complete avulsion or laceration

Picture 7: Palmaris Longus tendon in the forearm is often used as a donor tendon for grafting (no functional impairment is caused by its removal)

Picture 8: Silicon rod (yellow structure) inserted to recreate flexor tendon tunnel (sheath)

Picture 9: Exchange of the silicone rod with tendon graft
