What is the function of the ligaments in the hand?
There are six major ligaments in the hand, and they function to give stability to the wrist. These ligaments join the carpal bones and the radius together, and they also link the two different rows of carpal bones together. The ligaments that link the carpal bones together keep the bones in place while the wrist moves around.
What are ligaments and tendons in the wrist?
Ligaments attach bones to bones and tendons attach muscles to bones. The wrist and hand are made up of many bones and thus have many ligaments and tendons that provide stability and facilitate movement. A partially or completely torn ligament or tendon may require surgical intervention.

The four ligaments responsible for maintaining the stability of the joint are the palmar and dorsal radiocarpal ligaments and the ulnar and radial collateral ligaments.
What is a torn ligament in hand?
A hand sprain is an injury to a ligament, the strong tissue that connects bones. In a hand sprain, the ligament has been stretched or torn. This commonly occurs when a person falls on his or her outstretched hand.
How do you know if you tore a ligament in your hand?
Signs of a ligament injury include pain and swelling that's similar to many other hand and wrist injuries. The wrist may also look bruised or discolored, and feel painful for several weeks. In some cases, a ligament injury may go undiagnosed, causing the joint to heal improperly.
What happens if a tendon is cut?
If a tendon is torn or cut, the ends of the tendon likely will be pulled apart, making it impossible for the tendon to heal on its own because of the gap between the two ends. It is not uncommon for other structures to be injured at the time of a cut flexor tendon.
What happens if a torn tendon is not repaired?
Left untreated, injuries like partial tendon tears can become full ruptures that leave no connection between bones and muscle. Achilles tendon ruptures and ACL ruptures can disable your ability to put weight on your legs, bend or straighten your knees, stand on tiptoe, or walk with a normal heel-to-toe stride.
What's the difference between ligament and tendon?
A tendon serves to move the bone or structure. A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.

What connects the muscles in the arm to the bone?
The tendons connect muscles in the arm or hand to the bone to allow movement. In addition, there are arteries, veins and nerves within the hand that provide blood flow and sensation to the hand and fingers.
What are the ligaments on the palm side of the hand?
There are 2 Collateral Ligaments one on each side of each joint in the finger to provide stability. Joint instability can limit finger range of motion (ROM) to perform full flexion with making a tight fist or full extension to lay hand flat on the table. The Annular Ligaments of the hand and finger are referred to as pulley’s which form tunnels on the palm side of the hand and into the finger for the tendons to pass through. Injury to a pulley can cause bowstring of tendon and limited smooth motion. Digital Cutaneous Ligaments tether the skin to the bone to prevent increased movement of the skin when gripping. The Central Slip and Lateral Bands are ligaments that are components of Expansion Hood on the dorsum/back of the finger which help extend fingers. Injury to the Central slip can prevent a person from fully straightening the finger.
What is the most common ligament injury of the finger?
The most common ligament injury of the finger is to the middles joint. It referred to as proximal interphalangeal joint (PIP joint). People will refer to this injury as “jamming my finger”. A common injury to the middle joint is to the Volar Plate which is a sturdy band of connective tissue that prevents hyperextension of the finger. The Volar Plate can be partial or fully torn due to backward force.
How long does it take for a finger to heal from a torn ligament?
Buddy taping two fingers together for stability or finger splint can promote the healing of ligaments by reducing the stress to the ligaments. X-rays may be necessary to check for fractures.

What Are the Ligaments of the Wrist?
Ligaments are thick bands of connective tissue that connect one bone to another. The wrist has an extensive network of ligaments that can be divided into two types.
Why are Wrist Ligaments Important?
Ligaments connect one bone to another and provide important stability for the wrist. Injury of the ligaments in your wrist can disrupt this stability resulting in wrist instability . This is similar to a loose lug-nut on your car wheel. The excessive play in the wheel compromises your ability to drive, the safety of the car and leads to premature wear and tear of the tire. So too with the wrist. Loose ligaments allow excessive motion in the joint which can cause injury to the ligaments, tendons, and the onset of arthritis.
What is the best treatment for a wrist injury?
Grade 1 and 2 wrist injuries can be treated with precise ultrasound injection of PRP or bone marrow concentrate. PRP is rich in platelet growth factors that can increase blood flow and accelerate ligament healing. Bone marrow concentrate contains many different types of your own body’s cells that can promote ligament healing and reorganization of the disrupted fibers. At the Centeno-Schultz Clinic, we are experts in the treatment of ligament hand ligament pain and injuries. The procedures are demanding and require advanced training. Wrist ligaments are small in size and require ultrasound guidance to be injected. Injections without ultrasound guidance, otherwise known as blind injections, can not accurately target and treat specific ligaments. To learn more about precise ligament injections watch Dr. Pitts in the video below.

The tendons move the bones when the muscles contract. The tendons in the hand include the superficialis tendons, the extensor tendons, the flexor tendons, the extensor pollicis brevis, the pollicis longus, and the profundus tendons. Tendons attach the bones to the muscles of the hand and arm. The muscles which move the thumb ...
How many phalanges are there in the finger?
There are three phalanges in each finger, and the proximal phalanx is the largest out of the phalanges. The proximal phalanx has joints that connect with the middle phalanx and the metacarpal. The middle phalanx of the finger is second or middle of the three different bones in the fingers. The distal phalanx is the third or final bone in each ...
Which tendons are responsible for flexing the wrist?
The superficialis tendons are responsible for flexing the wrist along with the PIP and MCP joints, aided by the profundus tendons. These tendons are linked to the bases of the middle phalanges and they run through the wrist and hand along the palm side of the hand. Finally, the profundus tendons are also responsible for moving the PIP and MCP joints and they are attached to the distal surface of the middle phalanges.
What are the bones of the hands?
The bones found in the hands and fingers include the carpals, the metacarpals, the proximal phalanges, the middle phalanges, and the distal phalanges. The metacarpals found in the fingers are the bones which make up the largest portion of the hand. They are located in between the carpals (see the wrist below) and the phalanges.
What is the third bone in the hand?
The distal phalanx is the third or final bone in each finger, when counted from the base of the hand to the ends of the fingers. Because it is on the end, the distal phalanx only joins with the middle phalanx. The thumb, unlike the four fingers, is made out of only the distal phalanx , the proximal phalanx, and the thumb’s metacarpal.
How to know if you have ligaments in your hand?
The first clue that you may have a ligament injury is having a traumatic event occur where the hand is forced into an unnatural position, or if it sustains some sort of blunt force, like during a fall. When this happens, the strong tissue that connects the bones can be injured. This can cause pain, swelling and bruising around the injury, and the area might feel weak or ‘loose’. Immediately after the injury, the “RICE” protocol should be followed, which includes Rest, Ice, Compression and Elevation, then schedule an appointment with a hand doctor who can evaluate if further treatment is needed.
How to treat a ligament injury in the hand?
Ligament injuries are often treated by immobilizing the injured area with a splint or cast and by treating the inflammation with anti-inflammatory medications. Sometimes, however, for an extensive injury, a hand specialist may recommend surgical repair. Severe injury can lead to permanent deformation or reduction of mobility, so it’s important to consult a hand doctor if you suspect a ligament injury in the wrist, fingers or hand.
What is the hand specialist?
A hand specialist will examine the hand and ask for an explanation of how the injury occurred in order to understand the type of trauma that caused the injury. This will give them an idea of the structures that may be damaged. The hand specialist may also order diagnostic tests, such as an x-ray, MRI ultrasound or CT scan, to confirm the type of injury sustained.
What are hand ligaments?
Ligaments are tough pieces of connective tissue that join one bone to another. Ligaments are attached on either side of a joint, strengthening and stabilizing it by limiting excess motion of the bones. Injuries to ligaments are very common; in fact, what we call a sprain is actually an injury to the ligaments of the “sprained” joint. The hand is particularly susceptible to ligament injuries simply because it gets so much use and thus is exposed to many possibilities for injury. One common place for a hand ligament injury to occur is in the scapholunate ligament. This ligament connects the scaphoid and the lunate, two of the small carpal bones, which make up the wrist and base of the palm.
What are the treatment options for a hand ligament injury?
In many cases, conservative treatments such as splinting or casting the injured wrist/hand and taking anti-inflammatory medications are sufficient.
What is a scapholunate ligament tear?
The scapholunate ligament is responsible for ensuring that the two bones – scaphoid and lunate – move in unison. This ensures smooth rotation of the wrist. When this hand ligament is torn, the scaphoid and lunate move in different directions, which results in pain and loss of strength when gripping.
Where can I find treatment for my hand ligament injury in NYC?
Dr. Steven Lee is the Chief of Hand and Upper Extremity Surgery at Lenox Hill Hospital in NYC and has been consistently recognized as one of New York’s top orthopedic doctors by New York Magazine and Castle Connolly. If you are suffering from symptoms of a hand ligament injury and evaluating your treatment options, schedule a consultation with Dr. Lee today.

What is a sprain in the hand?
Injuries to ligaments are very common; in fact, what we call a sprain is actually an injury to the ligaments of the “sprained” joint. The hand is particularly susceptible to ligament injuries simply because it gets so much use and thus is exposed to many possibilities for injury.
What does it feel like to have a hand ligament injury?
While hand ligament injuries are often obvious due to the local pain and swelling that accompanies them, the severity of such injuries is easy to misjudge. Symptoms vary depending on the severity of the injury, but commonly include pain on the thumb side of the wrist, swelling and/or bruising, loss of grip strength, and sometimes a snapping or popping in the wrist.
What Does Repair of Hand and Wrist Ligaments and Tendons Treat?
An accident or injury, such as a fall onto an outstretched hand or direct blow to the hand or wrist may cause a hand or wrist ligament tear. Osteoarthritis can also make patients more susceptible to a tear. Hand or wrist ligament tears may cause any of the following symptoms:
How to repair a torn ligament?
First, a tiny incision is made near the torn ligament or tendon. Next , sutures are used to attach torn tendon ends or suture anchors are used to attach the ligament to the bone.
What is hand splint?
The splint holds the wrist and hand in a position that gently stretches the tendon or ligament to prevent tightness and scar tissue. Hand therapy after surgery is a very important part of recovery. The patient and hand therapist perform stretching and strengthening exercises together to regain complete wrist and hand function.
What is the repair of the wrist and hand?
What is Repair of Hand and Wrist Ligaments and Tendons? Ligaments attach bones to bones and tendons attach muscles to bones. The wrist and hand are made up of many bones and thus have many ligaments and tendons that provide stability and facilitate movement.
