From the nail down the distal phalances, distal interphalangeal joint, the middle phalanges and then the proximal interphalangeal joints. The base of the finger is comprised of the proximal phalanges and the knuckles.
There are 9 interphalangeal joints in an anatomically normal hand: 2 in each finger and 1 in the thumb.

Finger joints are condyloid joints.It is the Hinge Jointthey are called proximal interphilangeal jointsThe joint of the finger can be called the knuckle or saddle joint for the thumb.Hope that helped.hinge jointsSynovial joints .
Simply put, there are nine (9) interphalangeal joints in the hand. The hand consists of 5 digits numbered 1-5 from thumb to "pinkie". Digit 1 (thumb) has two phalanges one called the proximal phalanx and another called the distal phalanx. So, there is one interphalangeal joint between the proximal and distal phalanges of the thumb. Digits 2-5 each has three phalanges a proximal phalanx, a middle phalanx and a distal phalanx. So, each digit has 2 interphalangeal joints.
The joints at the base of the fingers are called metacarpal phalangeal joints (MPJ's) and form knuckles when you make a fist. These are elliposoidal joints. The ones that are in the fingers themselves are called interphalangeal joints. The thumb only has one called a proximal interphalangeal joint (PIP) and the other four fingers each have two. The first one is called the proximal interphalangeal joint (PIP)and the last one is the distal interphalangeal joint (DIP. These are all hinge joints.
Finger reattachment (or replacement) is defined as reattachment of the part that has been completely amputated.
The extensor digiti minimi extends the minimum digit, ie. it straightens the interphalangeal joints of the pinky finger.
The most expensive finger as far as replacement would be the middle finger. This finger has many ligaments that would need to be microscopically operated on in order to attach the finger and get the best use out of the hand.
Sesamoid bones are also found occasionally at the metacarpophalangeal joints of the middle and ring fingers, at the interphalangeal joint of the thumb and at the distal interphalangeal joint of the index finger. In the lower extremity the largest sesamoid bone of the joints is the patella, developed in the tendon of the Quadriceps femoris.
The area between the thumb and index finger (digitus secundus manus, pointer finger, or forefinger), is called the thenar space. The skin is called webbing. In other sources it is called thumb webbing. The muscles at the base of the thumb form the thenar eminence.
