Laceration of the extensor digitorum communis tendon just proximal to its insertion at the proximal phalangeal base. A common example is a distal avulsion of the ED from the distal phalanx (“mallet finger”), with or without an avulsion fracture. The mechanism for the closed injury is most commonly sudden, forceful flexion of the DIP joint in an extended digit. Wieschhoff GG, Sheehan SE, Wortman JR et-al. A high proportion of mallet finger injuries will present as isolated tendon injuries without any associated avulsions fractures known as a "mallet fracture" 5. A 49-year-old man jams his left index finger playing softball. Check for errors and try again. With mallet finger, the tendon on the back of the finger (not the palm side) is separated from the muscles it connects. Observe skin color, warmth, and capillary refill to assess blood flow, Evaluate sensation to light touch and two-point discrimination to assess integrity of the digital nerves, Inability to extend the distal phalanx actively, Most tenderness to palpation over the dorsal distal phalanx and DIP joint, Possible compensatory swan neck deformity, Possible subungual hematoma (blood under the nail plate). The alternative is for fixation with a screw or hook plate if the fragments size will accommodate. This injury is caused by hyperflexion of the distal interphalangeal joint, resulting in avulsion of the attachment of the extensor tendon from the base of the distal phalanx.

There is slight flexion at this joint, which is where the term "mallet" comes from - the finger position resembles a mallet (for example, a piano key mallet). The bony mallet finger refers to the avulsion fracture at the phalangette basilar part caused by traction of the extensor tendon when the original trauma occurs, leading to a limited extension of the distal phalanx. They are the most prevalent finger tendon injury in sport. Clavero JA, Alomar X, Monill JM et-al. The loss of continuity of the extensor tendon over the distal interphalangeal joint may cause the deformity called mallet finger. Findings are consistent with a mallet fracture and orthopedic review is recommended. Sonographic imaging of mallet finger. Injury to these structures commonly results from direct axial or flexion loading of the DIP joint, as can occur by direct blow from a ball. Dorsal avulsion of the distal phalanx base; Soft tissue swelling; In this case the extensor tendon is intact Chronic injury can result in swan-neck deformity (hyperextension PIP) They may represent an isolated tendinous injury or occur in combination with an avulsion fracture of the dorsal base of the distal phalanx. 1. —Mallet finger results from disruption of the extensor tendon at its insertion site at the dorsal aspect of the distal phalanx base, and mallet finger is the most common finger tendon injury in sports . baseball, basketball), or a crush injury (slamming a door towards the distal interphalangeal joint) in the extensor direction. Posteroanterior (PA) and lateral radiographs centered at the distal interphalangeal (DIP) joint of the affected finger are required. Masks are required throughout all facilities. There are a few different ways this can happen. The patient with a mallet finger not only has a painful and swollen distal finger but is unable to extend the DIP joint actively. The joint rests in an abnormally flexed position. Trigger finger; We take a multidisciplinary approach to treatment, getting input from all of the medical areas that are involved with your care.

MRI is used with increasing frequency by hand surgeons and other clinicians to help in the evaluation of patients presenting with suspected ligament and tendon injuries of the fingers. This can damage the tendon and bone, causing the finger to droop. The extensor tendon is damaged (possibly ruptured). The injury classically occurs while playing sports where the DIP undergoes sudden flexion (extended finger is struck at the tip by an object, e.g. The joint rests in an abnormally flexed position.

This can include dorsal ulceration, nail deformities and maceration of the skin. It is characterized by an inability to extend the distal phalanx at the distal interphalangeal (DIP) joint. Classically, they occur during athletic activities, when an extended finger is struck at the tip by a basketball, volleyball, baseball, or softball. A pure tendon injury shows no evidence of fracture, only the mallet deformity (Fig. Sometimes, the tendon itself tears rather than avulsing the bone fragment, in which case … Non operative treatment would usually involve 6 weeks of full time splinting followed by 6 weeks of night splinting 8. 5.
