In most cases this causes soft tissue inflammation and rarely injures the bone itself.

Striking the back of the hand against an object.

Trauma to the knuckles may arise with one or more of the following factor : However, it is sometimes difficult to differentiate between pain in the bone or joint and therefore knuckle pain from both areas is discussed collectively. Knuckle joint pain is often caused by overusing the hands and finger leading to muscle, tendon and joint strain. Knuckle bone pain is more commonly a result of injury, particularly with an impact on a hard object. Another term, knuckle joint, is used to refer to the hand-finger joints (metacarpophalangeal joint) and finger-finger joints (interphalangeal joints). This is sometimes commonly referred to as the knuckle bone. The hand knuckles are the bony protrusions formed by the head of the hand bones (metacarpals).

Finger-finger joint – interphalangeal joint (IP joint).

Hand-finger joint – metacarpophalangeal joint (MCP joint).The joints of the hands and fingers are named as follows : The outer lying finger bones are known as the distal phalanges. Between the two finger bones (absent on thumb) is the intermediate (middle) phalanges. The finger bones closest to the hand bones are known as the proximal phalanges. The base articulates with the wrist bones (carpal) and the head articulates with the finger bones (phalanges).Įach finger has 3 bones (phalanges) except for the thumb which has 2 bones. The hand bones (metacarpals) have three parts – a base, shaft and head. Fingers : 14 bones (finger bones or phalanges).Hand (palm) : 5 bones (hand bones or metacarpals).Wrist : 8 bones (wrist bones or carpals).The number of bones in each part of the hand is as follows : The human hand has 27 bones which move at joints (articulates) to make the hand one of the most flexible parts of the body. However, there are several other causes of knuckle pain that may not be caused by injury and can be related to underlying diseases with severe complications. It is easily injured when the hands and fingers, particularly when clenched, strikes against any object because there is very little tissue surrounding and protecting it. The hand knuckles are most prominent when the hand is clenched into a fist. The term is more common when referring to the hand and especially to the head of the hand bones where it meets the finger bones. The knuckles refers to the joints of the fingers and toes and in particular to the bony bumps located by these joints. Some types of injury and certain diseases tend to affect specific joints, while at other times the disorder may not be as discriminatory and there is generalized arthritis. Similarly, the pain may be isolated to a single joint (monoarticular pain) or affect several joints at the same time (polyarticular pain). Pain may occur in small or large joints only or in both simultaneously.

It can be associated with other signs and symptoms like stiffness, swelling of the joint, redness of the overlying skin and decreased mobility. Joint pain is known as arthralgia and may affect any joint in the body. From bearing the body weight to endlessly moving in daily activity, joints are prone to a range of injuries and diseases as is the case with any part of the body. The joints experience a significant amount of stress and strain throughout life.
