What attaches to distal phalanx of thumb?
On the thumb, the extensor pollicis brevis tendon attaches to the dorsal aspect of the base of the proximal phalanx, and the extensor pollicis longus tendon attaches to the distal phalanx 1.
What does it mean when your proximal phalanx hurts?
Metatarsalgia is pain that occurs in the foot between the arch and the toes, often in the metatarsophalangeal joint of the big toe. It is usually associated with problems with foot biomechanics or deformities. Tenderness and pain when walking are common symptoms.
What is the difference between phalanx and phalanx?
In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones….

What muscle inserts on the distal phalanx?
The distal phalanges are capable of flexion and extension at the DIP joints. Two forearm extensors and one flexor muscle insert directly into the bases of the distal phalanges, permitting these actions. These include flexor digitorum profundus, flexor pollicis longus and extensor pollicis longus.
Which tendon controls the thumb?
Abductor pollicis longus (APL) tendon It attaches to the metacarpal bone of the thumb and helps pull the thumb away from the rest of the hand. This tendon along with the extensor policies brevis tendon can get inflamed and painful.
What is PIP and DIP?
The PIP and DIP joints are hinge joints between proximal and middle phalanges and between the middle and distal phalanges respectively.
How long does it take for a proximal phalanx fracture to heal?
Many stable phalanx fractures can be treated nonoperatively through close monitoring until clinical healing is noted. Proximal phalanx fractures will often be clinically healed 4 weeks status post injury, at which time it is unlikely that the fracture will displace.
Why does my 1st MTP joint hurt?
Metatarsophalangeal joint pain most often results from misalignment of joint surfaces, causing synovial impingement with only minimal warmth and swelling, but may be the initial manifestation of rheumatoid arthritis. Patients have dorsal and plantar joint tenderness with usually minimal signs of acute inflammation.
Did the Romans use phalanx?
The Romans had originally employed the phalanx themselves but gradually evolved more flexible tactics. The result was the three-line Roman legion of the middle period of the Roman Republic, the Manipular System. Romans used a phalanx for their third military line, the triarii.
Where is the phalanx bone located?
The phalanges are comprised of the proximal, middle, and distal groups. The proximal bones are located just below the knuckle, while the middle bones are located above the knuckle. The distal phalanges are the fingertips.
Where is the FDP tendon?
forearm
Flexor digitorum profundus (FDP) tendons They run down the forearm and within the carpal tunnel. The four tendons glide in sheaths along the hand and fingers and insert into the fingertip bone. These tendons run closer to the bone compared to the rest of the flexors in the hand and fingers.
Which tendon moves the thumb?
The FPL tendon bends the thumb. It is unique to humans. It starts as a muscle in the forearm and then travels as a tendon in the wrist through the carpal tunnel. It is then covered by a tunnel, or sheath, and inserts into the most distal (farthest from your body) bone in the thumb.
What is the proximal phalanx?
What is the Proximal Phalanx A proximal phalanx (plural: phalanges) is one of the tubular long bones located in the bottom row of the phalanges or finger bones. Each proximal phalanx has a head, a body/shaft, and a base. Where are the Proximal Phalanges Located
What is a flexor hallicus longus tendon transfer to the proximal phalanx?
A flexor hallicus longus (FHL) tendon transfer to the proximal phalanx is used to treat clawing of the toe. Small muscles in the foot help to stabilize the toes. When those muscles are weakened by disease, an imbalance occurs that leads to clawing. The clawing puts abnormal pressure on the ball of the foot that can cause an ulcer to form.
Which finger does the proximal phalanx of the thumb articulate with?
Proximal phalanx of the thumb articulates with the first metacarpal. Proximal phalanx of the index finger articulates with the second metacarpal. Proximal phalanx of the middle finger articulates with the third metacarpal. Proximal phalanx of the ring finger articulates with the fourth metacarpal.
What causes the flexor pollicis longus to rupture?
Spontaneous rupture of flexor pollicis longus tendon by tendolipomatosis in proximal phalanx: A case report Spontaneous rupture of the FPL tendon, attributed to degenerative changes caused by tendolipomatosis, is the first report of its kind, in the authors’ opinion.
