Proximal phalanx finger

Is the thumb proximal to the finger? In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. What are proximal phalanges?


There is one proximal phalanx in each finger (including the thumb), which means there are five proximal phalanges in each han a total of ten in both. These are sometimes specifically referred to as the first (thumb), second (index finger ), third (middle finger ), fourth (ring finger ), and fifth (little finger ) proximal phalanx.

Each finger has three phalanges, except the thumb, which has two phalanges. A broken, or fracture finger occurs when one or more of these bones breaks. A break is usually the result of an injury. A dorsal PIP dislocation is the most common type of finger. They are named proximal because they are the closest phalanges to the metacarpals.


The periosteum of the proximal and middle phalanges form the dorsal wall of fibro-osseous tunnel in which flexor tendon glide, when violated by a fracture flexor tendon adhesions may develop and reduce motion in this manor as well. Fractures of the proximal phalanx can be complex owing to forces exerted on the fracture fragments by a number of muscles and tendons which often result in angular or rotational deformity. This topic review will discuss fractures of the proximal phalanx.

The proximal phalanx (PP) of the fingers is fractured more frequently than the middle or even distal phalanges. The problems of malunion, stiffness and sometimes loss of skin or other soft tissues associated with PP fracture increases the disability. The optimum treatment depends on fracture. When functional disability is severe, surgical correction is mandatory. PIP joint dislocation is the most common injury in the han especially in young athletic individuals.


A thumb proximal phalanx fracture is a disruption of the mechanical integrity of the proximal phalanx. Instructions Laith Al-Shihabi, MD 3-days Patients are seen and ! Finger Phalanx Fracture ORIF ! Splint: -For proximal phalanx fractures, a hand-based P1-blocking splint is fashioned holding the MP joints of the injured ! Proximal Phalanx Base (not involving the joint) These are typically transverse i. A) Adults This typically follows a fall with the finger tipping back most often affecting the little finger. The first bone in your finger is called the proximal phalanx , the middle finger bone is called the middle phalanx , and the finger tip bone is called the distal phalanx.


In this talk we will look at the diagnosis and treatment of a broken proximal or middle phalanx. If your proximal phalanx fracture is stable and undisplaced (ie the fragments are still in their normal position) it is unlikely that you will need surgery. This is the American ICD-10-CM version of S62. A - other international versions of ICD-S62.


The image shows a diagram of where these bones lie in the foot—the midpoint of the proximal phalanges being where to the toes branch off from the main body of the foot.

The useful range of motion of the PIP joint is 30–70°, increasing from the index finger to the little finger. During maximum flexion the base of the middle phalanx is firmly pressed into the retrocondylar recess of the proximal phalanx , which provides maximum stability to the joint. Note the surrounding bone marrow edema (arrowhead).


Nabil Ebraheim - Duration: 2:32. The patient has given full written consent for the filming and use of this video on. The palmar aspect of the little finger was black. The finger was extremely tender to light touch and swollen over the proximal two thirds of the finger. Medical Examination Findings.


Plane film radiographs of the finger were taken on the th. There was a complete separation of the shaft of the proximal phalanx.
