How do you stop a MCP joint dislocation?
The suggested reduction technique for a simple MCP joint dislocation is flexion at the wrist and proximal interphalangeal joint to relax flexor tendons while pressure is applied to the proximal phalanx at the base.
How do you treat a dislocated thumb?
How can you care for yourself at home?
- Wear the splint day and night until your follow-up visit.
- Take pain medicines exactly as directed.
- Put ice or a cold pack on your thumb for 10 to 20 minutes at a time.
- Prop up your hand on a pillow when you ice it or anytime you sit or lie down.
How do you relocate a dislocated thumb?
An X-ray is usually used to diagnose a dislocated thumb. The bones may move back into place on their own or a doctor may gently put the joint back with a quick maneuver called a reduction. In some cases, surgery is needed to repair the joint.
How do you fix a dislocated thumb MCP?
Following closed reduction, the thumb is immobilized in a forearm-based thumb spica splint or cast with the MCP joint in extension for 4-6 weeks in thumb MCP joint volar dislocations. Thumb radial collateral ligament injuries may be treated in a forearm-based or hand-based thumb spica cast for 4 weeks.
How do you stop a dislocated thumb MCP?
Apply distal pressure either on the volar base of the distal phalanx (for IP dislocations) or on the proximal phalanx (for MCP dislocations). Achieve reduction by moving the dislocated joint into a position of relative extension without hyperextending the joint.
How long does dislocated thumb take to heal?
Once the joint is back in place again, it will take about 6 to 8 weeks or more for the ligaments to heal. During this time, your thumb should be protected from re-injury. This may be done with a cast or splint. Finger splints prevent motion at the joint.
What is thumb CMC?
The thumb carpometacarpal (CMC) joint, a biconcave-convex saddle joint, consists of the articulation between the first metacarpal of the thumb and the trapezium carpal bone. Other significant articulations of the trapezial bone are the scaphoid and trapezoid carpal bones and the second metacarpal bone.
Why does my MCP joint hurt?
Causes of Metacarpophalangeal (MCP) Joint Arthritis Traumatic injury leading to broken bone or loss of cartilage (Post-traumatic arthritis) Routine wear and tear of the MCP joint (osteoarthritis) Certain medical conditions (gout, pseudogout, psoriasis, etc.) Infections (after a cut, puncture or animal bite)
How long does it take for a dislocated thumb to recover?
How are dislocations of the metacarpophalangeal joint treated?
Summary MCP Dislocations are a dislocation of the metacarpophalangeal joint, usually dorsal, caused by a fall and hyperextension of the MCP joint. Diagnosis can be made clinically and is confirmed by orthogonal radiographs. Treatment is closed reduction unless soft tissue interposition blocks reduction, in which case open reduction is indicated.
When to use a dorsal splint for MCP dislocation?
Simple dorsal: Dorsal blocking splint to prevent extension beyond neutral with the MCP joint in 50–70 degrees of flexion for 7–10 days if no evidence of significant instability; buddy taping also may be implemented. Active flexion exercises are permitted. With thumb MCP dislocations, a thumb spica splint is used for immobilization ( 1, 2 ) [C].
What kind of joint is the thumb metacarpophalangeal?
The thumb metacarpophalangeal (MP) joint has features of both a ginglymus (hinge) joint and a condyloid joint. The joint moves mostly in a flexion-extension mode (ginglymus style), but there are also elements of rotation and abduction-adduction in the normal joint (condyloid).
How are dorsal dislocations of the thumb more common?
PATHOGENESIS Dorsal dislocations of the thumb MP joint are much more common than are volar dislocations.4,5 The typical mechanism is a hyperextension force strong enough to rupture the volar plate and joint capsule. Occasionally, the radial or ulnar collateral ligaments (or both) of the MP joint are ruptured along with the volar plate.
