• #1 Mallet Finger: What It Is, Complications & Recovery Time

  https://my.clevelandclinic.org/health/diseases/21825-mallet-finger

  Mallet finger occurs when the tip of your finger droops downward. An injury to your extensor tendon causes it. […] Any traumatic injury that weakens, tears, cuts or dislocates the terminal extensor tendon at the tip of your finger can cause mallet finger. Extensor tendons allow you to extend (straighten) your finger joints. If the tendon cant pull on your fingertip, you wont be able to straighten it. This can happen if: […] A hard impact forces the tendon away from the bone […] A jammed finger stretches or tears the tendon […] A penetrating injury cuts through the tendon […] You break your finger and the bone pulls away from its normal position with the tendon attached […] Your finger joint dislocates and stretches the tendon […] Swelling and inflammation in your finger from arthritis gradually weaken the tendon and cause it to rupture.

  https://orthoinfo.aaos.org/en/diseases–conditions/mallet-finger-baseball-finger/

  Mallet finger is an injury to the thin tendon that straightens the end joint of a finger or thumb. […] The injury can happen when an unyielding (rigid or solid) object (like a baseball) strikes the tip of a finger or thumb and forces it to bend further than it is intended to go. […] In a mallet injury, when an object hits the tip of the finger or thumb, the force of the blow causes a tear near the insertion (attachment) of the extensor tendon at the last joint of the digit. […] While the force to cause this injury is typically large, a minor force, such as tucking in a bed sheet, will sometimes cause a mallet finger. […] The injury may either rupture the middle of the tendon or pull the tendon away from the place where it attaches to the finger bone (distal phalanx). […] In some cases, a small piece of bone is pulled away along with the tendon.

  Any forced flexion of the finger while it is held in an extended position risks the integrity of the extensor mechanism at the DIP joint. The classic mechanism of injury is a finger held rigidly in extension or nearly full extension when the finger is struck on the tip by a softball, volleyball, or basketball. Other common mechanisms of injury include forcefully tucking in a bedspread or slipcover or pushing off a sock with extended fingers. A direct blow over the dorsum of the DIP joint may also produce mallet finger. […] Mallet deformity can also be associated with a fracture of the dorsal articular surface of the distal phalanx. Radiographically, these bony avulsions can be characterized into three common patterns, as follows: A tiny fleck of bone that involves less than 25% of the articular surface; A large bony fragment that involves 30% or more of the articular surface; An avulsion of any size that is associated with palmar subluxation of the distal phalanx.

  Mallet finger is the term usually applied to extensor avulsion fractures. However, this entity may also be caused by distal extensor tendon ruptures. Either one results in an inability to extend the DIP joint. Mallet finger injuries are caused by the disruption of the extensor mechanism of the phalanx at the level of the distal interphalangeal joint, usually due to a forced flexion at the distal interphalangeal joint. […] The distal extensor tendon is ruptured. The rupture occurs when the distal phalanx of a finger is forced into flexion while being actively extended. […] A mallet finger injury occurs when the extensor tendon is disrupted. In contrast, a mallet fracture occurs when the tendon injury causes an avulsion fracture of the distal phalanx.

• #5 Mallet Finger: Causes, Symptoms, and Treatment

  https://www.healthline.com/health/mallet-finger

  Mallet finger is a common injury caused when an impact damages the tendon of a fingertip. […] In sports, any direct hit to your extended fingers from a baseball (or football, basketball, or volleyball) can rupture the tendon that straightens the tip of your finger. This is known as the extensor tendon. […] Although a hard blow to the tendon is the cause of most mallet finger injuries, sometimes a minor force can injure the tendon. […] Mallet finger occurs most often among young men in sports activities. In children, the injury occurs more often from a direct shock, like crushing a finger in a door. […] An impact injury to the extensor tendon will prevent you from straightening your fingertip. […] A tendon is like a rope made up of collagen (protein) fibers that attach your muscles to your bones. An impact injury to the finger may tear only the soft tissue of the tendon. Or it may pull the tendon away from the fingertip bone (distal phalange). Sometimes a fragment of bone will pull away with the tendon.

  Loss of the extensor mechanism at the distal interphalangeal (DIP) joint leads to mallet finger also known as baseball finger or drop finger. This can be secondary to tendon substance disruption or to a bony avulsion. […] Soft tissue mallet finger is the result of a rupture of the extensor tendon in Zone 1, and a bony mallet finger is the result of an avulsion of the extensor tendon from the distal phalanx with a small fragment of bone attached to the avulsed tendon. […] Injury to the extensor mechanism at the distal interphalangeal (DIP) joint can lead to mallet finger also known as baseball finger or drop finger. This can be secondary to tendon substance disruption or to a bony avulsion. […] The most common mechanism of injury in mallet finger is a sudden flexion of the DIP joint with the resistance force directed along the long axis of the finger. This leads to terminal extensor tendon tear or tendon avulsion with a bony fragment.

  Trauma to a finger usually causes mallet finger. This injury most commonly occurs in sports, particularly when trying to catch a ball that then strikes the tip of a finger—which is why it is often called baseball finger. […] A direct blow to the finger causes mallet finger. Most commonly, the injury happens when you are trying to catch an object, but the object hits the top or tip of your finger rather than landing in the palm of your hand. […] Although most mallet fingers are caused by a hard blow to the finger during sports, they can also be the result of something that doesn’t seem serious at first. Jamming your finger while reaching for something on a shelf or even tucking in a bedsheet can pull the tendon away from the bone and cause pain and deformation of your finger.

• #16 Mallet Finger: Symptoms & Treatment | The Hand Society

  https://www.assh.org/handcare/condition/mallet-finger

  A mallet finger is a deformity of the finger typically caused by injury. […] The cause of this condition is an injury to the extensor tendon, which straightens the end joint just before the fingernail. There are two types of mallet finger. The first type is an injury to the extensor tendon itself called a rupture. This can happen fast from jamming or cutting the finger, and it can happen slowly from arthritis stretching out the tendon over time. […] The second type is a broken bone at the extensor tendons attachment site that prevents the tendon from pulling on the whole bone. The tendon itself is intact, but the bone it attaches to breaks off. […] Mallet fingers can happen when an object (such as a ball) strikes the tip of the finger or thumb. The force can cause either the tendon or broken-bone type of mallet finger.

  https://www.bssh.ac.uk/patients/conditions/28/mallet_finger_injury

  A mallet finger injury is a tear of tendon that straightens the end joint of the finger. It is often caused by catching the finger end-on during sport, but it sometimes results from a minor injury such as catching the finger when tucking in bed sheets. […] The tendon may tear where it joins on to the end bone of the finger, or it may pull off a small fragment of bone at this point (in which case it is called a mallet fracture).

• #18 Mallet Finger: Practice Essentials, Anatomy, Etiology

  https://emedicine.medscape.com/article/1242305-overview

  From experimental studies, the rate of loading determines whether a tendon (or ligament) ruptures in midsubstance or is avulsed from its bony attachment. Rapid loading rates are more likely to cause a tear in the tendon itself, while lower loading rates are more likely to cause a bony avulsion. This is because the bone is relatively more viscoelastic than the tendon.

  Mallet finger is a deformity that occurs when an injury disrupts a tendon at the joint near the tip of a finger and prevents it from straightening. […] Mallet finger can be due to disruption of the tendon alone or it can involve a small fragmentation of the bone. […] Mallet finger can be caused by a simple action or it may be the result of a direct blow on the finger. […] A mallet finger is caused when an object strikes the tip of an outstretched finger with force and damages the extensor tendon located near the fingertip. […] A mallet finger is caused when a ball, or any other object, strikes the tip of an outstretched finger with force and bends it. This causes damage to the extensor tendon, located at the distal inter phalangeal joint (DIP the joint near the finger tip), which plays a role in straightening the finger. […] In children, the injury may involve the growth plate, the growing part of the bone while in adults it may involve the joint surface.

  Mallet finger is most often caused by an object forcefully hitting the fingertip and bending the joint too far, which can result in a torn or detached tendon or even a broken bone. […] Any action that causes the joint to be forcefully bent can cause mallet finger. […] If left untreated, your finger could become stiff and have a higher risk of reinjury. Untreated mallet finger can also lead to a condition called swan neck deformity, where the joint below your injury becomes hyperextended to compensate for the flexion happening in the last knuckle. […] All of the tendons that straighten out your finger are an intricate balance of things, and when that balance gets disrupted, it can cause deformities like the swan neck deformity, where you might have trouble actually bending your finger.

  Mallet finger is a common injury that can cause significant pain and discomfort. It occurs when the outermost joint of the finger is injured, usually from a forceful impact or accident. […] When dissecting the mechanism that causes this injury, the most common mechanism of injury in mallet finger is a sudden flexion of the DIP joint with the resistance force directed along the long axis of the finger. This leads to terminal extensor tendon tear or tendon avulsion with a bony fragment. […] Mallet finger leads to an imbalance in the distribution of the extensor force between the proximal interphalangeal (PIP) and DIP joints. If left untreated, mallet finger leads to a swan neck deformity from PIP joint hyperextension and DIP joint flexion. […] Soft-tissue mallets can be quite complex and requires consistent patient compliance to ensure a positive result is meet as little as 1 mm of terminal tendon lengthening resulted in 25 of DIP joint extension lag.

  https://www.medicalnewstoday.com/articles/mallet-finger

  Mallet finger occurs when something forces the tip of a finger or thumb to bend further than usual. […] Sometimes, an object hits the tip of a finger or thumb with enough force to stretch or tear the extensor tendon, making the top of the digit droop. This is called mallet finger. […] Occasionally, the force of the impact pulls a piece of bone away with the torn tendon. This is called an avulsion fracture. […] Mallet finger is not a sign of arthritis. […] Sometimes, if the mallet finger injury damages a joint, a person may develop post-traumatic arthritis. […] The Arthritis Foundation says that people who have injured their joints are more likely to develop osteoarthritis, even if the joint has healed properly. […] It adds that fractures and dislocated joints are among the most common injuries that lead to arthritis.

  https://www.keilorroadphysio.com.au/blog-articles/mallet-finger

  Mallet finger injuries commonly result from direct trauma to the fingertip, which can occur in several ways. One of the most frequent causes is a direct blow to the tip of the finger, often seen in sports when a ball or object strikes the finger, forcing it to bend further than its natural range of motion. Another cause is forceful hyperextension, where the finger is pushed backward too aggressively, damaging the tendon responsible for straightening the fingertip. […] Risk factors for developing mallet finger primarily involve activities or professions that expose individuals to higher chances of finger injuries. Athletes, particularly those involved in ball sports like basketball, volleyball, or baseball, are at a significant risk due to the nature of the game, which often involves fast-moving objects coming into contact with the fingers. […] The significance of understanding and mitigating the risks associated with mallet finger cannot be overstated.
