The Hand Metacarpophalangeal (MP or MCP) Joint
The Hand Metacarpophalangeal (MP or MCP) Joint, also known as “the knuckle,” is formed by the articulation of the metacarpal head and proximal phalanx. This multiaxial joint allows flexion and extension as well as abduction and adduction motions. The MP joint also dynamically coordinates with the interphalangeal (IP) joint to perform thumb opposition and composite

Extensor Tendon Lacerations – Causes, Symptoms, Treatment
Extensor tendon lacerations are relatively common injuries and, when not treated appropriately, may result in a lasting impairment of hand function.[rx] Due to their superficial location and being adjacent to the bones, extensor tendons in the hand are more prone to injury than the flexors.[rx][rx] Causes of Extensor Tendon Lacerations Extensor tendon lacerations are very common

The Dislocation – Causes, Symptoms, Treatment
The Dislocation also called luxation, occurs when there is an abnormal separation in the joint, where two or more bones meet. A partial dislocation is referred to as a subluxation. Dislocations are often caused by sudden trauma on the joint like an impact or fall. A joint dislocation can cause damage to the surrounding ligaments, tendons, muscles, and nerves. Dislocations can occur in any joint

Joint Dislocation – Causes, Symptoms, Treatment
A joint dislocation, also called luxation, occurs when there is an abnormal separation in the joint, where two or more bones meet. A partial dislocation is referred to as a subluxation. Dislocations are often caused by sudden trauma on the joint like an impact or fall. A joint dislocation can cause damage to the surrounding ligaments, tendons, muscles, and nerves.[2] Dislocations can occur in any joint

Finger Joint Dislocation – Causes, Symptoms, Treatment
Finger Joint Dislocation is a common hand injury. Finger dislocation can occur at the proximal interphalangeal (PIP), distal interphalangeal (DIP), or metacarpophalangeal (MCP) joints. This paper discusses the epidemiology, anatomy, examination, imaging, treatment, and complications of finger dislocation. Finger Dislocation is a joint injury in which the finger bones move apart or sideways so the

Three-Dimensional (3D) C- Arm Computed Tomography
Three-dimensional (3D) C-arm computed tomography is a new and innovative imaging technique. It uses two-dimensional (2D) X-ray projections acquired with a flat-panel detector C-arm angiography system to generate CT-like images. To this end, the C-arm system performs a sweep around the patient, acquiring up to several hundred 2D views. They serve as input for 3D

Shoulder Pain – Causes, Symptoms, Treatment
Shoulder pain is a common indication for visits to primary care or orthopedic clinic worldwide. The estimated prevalence of shoulder complaints is 7% to 34%, often with shoulder impingement syndrome as the underlying etiology.[rx] Since it was first described in 1852, shoulder impingement syndrome is believed to be the most common cause of shoulder pain, accounting

The Adhesive Capsulitis – Causes, Symptoms, Treatment
The Adhesive Capsulitis, also known as frozen shoulder, is an inflammatory condition characterized by shoulder stiffness and pain. The American Academy of Orthopedic Surgeons defines adhesive capsulitis as, “a condition of varying severity characterized by the gradual development of global limitation of active and passive shoulder motion where radiographic findings other than osteopenia are absent.”

Glenohumeral Joint Instability – Causes, Symptom, Treatment
Glenohumeral Joint Instability encompasses both dislocation and subluxation events, and instability events commonly affect the general population. Approximately 1% to 2% of the general population will experience a glenohumeral dislocation in their lifetime.[rx] The young, active, athletic population is particularly susceptible to shoulder instability events. Over 95% of shoulder instability events occur in the anterior direction.[rx][rx] Over

Shoulder Subluxation – Causes, Symptoms, Treatment
Shoulder subluxation is defined as partial or incomplete dislocation of the glenohumeral joint or translation between the humeral head and glenoid fossa while the humeral head is in contact with the glenoid fossa.[rx][rx] The weakness of rotator cuff muscles or laxity of the glenohumeral ligaments causes the humeral head to easily slip out of the

The Shoulder – Anatomy, Nerve Supply, Functions
The shoulder is structurally and functionally complex as it is one of the most freely moveable areas in the human body due to the articulation at the glenohumeral joint. It contains the shoulder girdle, which connects the upper limb to the axial skeleton via the sternoclavicular joint. The high range of motion of the shoulder
