The layman's term "jammed finger" often refers to injuries that are incurred around the proximal interphalangeal (PIP) joint of the fingers. Although imprecise in its diagnostic accuracy, jammed finger aptly describes a constellation of injuries that are related to varying degrees of axial loading across the PIP joint.

The term mallet finger has long been used to describe the deformity produced by disruption of the terminal extensor mechanism at the distal interphalangeal (DIP) joint.1, 2, 3 Mallet finger is the most common closed tendon injury that is seen in athletes; this injury is also common in nonathletes after...

Posted 07/01/2007 HHG Handoll Introduction Date of Most Recent Substantive Amendment: 2004 03 04 Background Mallet finger, also called drop or baseball finger, is where the end of a finger cannot be actively straightened out due to injury of the extensor tendon mechanism. Treatment commonly involves splintage of the finger for six or more weeks....

Dislocation of a joint occurs when traumatic forces cause complete loss of continuity between the joint’s 2 articulating surfaces. Subluxation, on the other hand, occurs when the loss of continuity between the joints is only partial. A dislocation may or may not involve a fracture. Dislocations of the finger joints...

Phalangeal fractures are common injuries that may significantly affect hand function if not managed appropriately. Closed treatment has been the mainstay of treatment. Percutaneous pinning allowed the conversion of more unstable fracture patterns to stable configurations capable of tolerating early motion. More recently, minifragment screws and plates were developed to...

Sprains and dislocations of the metacarpophalangeal joint (MPJ) of the finger are relatively rare due to the protected position of this joint in the hand. Injuries to the MPJ of the thumb are more common, although these usually consist of collateral ligament injuries rather than dorsal or palmar dislocations.

Trigger Finger Due to Tenosynovitis From Mycobacterium Kansasii Infection in an Immunocompetent Patient By Hector Mejia, MD; Mark Ryzewicz, MD; Frank Scott, MD ORTHOPEDICS 2007; 30:1055
First described by Notta in 1850, a trigger finger, or stenosing tenosynovitis is caused by the discrepancy between the volume of the flexor tendon sheath and its...

If you think a broken (fractured) finger is a minor injury, think again. Without proper treatment a fractured finger can cause major problems. The bones in a normal hand line up precisely. They let you perform many specialized functions, such as grasping a pen or manipulating small objects in your... Highly Reputable

Phalangeal fractures are common injuries that may significantly affect hand function if not managed appropriately. Closed treatment has been the historical mainstay of treatment. Percutaneous pinning allowed the conversion of more unstable fracture patterns to stable configurations capable of tolerating early motion. More recently, minifragment screws and plates were developed...

A 35-year-old man was referred to our clinic by a neurosurgeon for hypersensitivity and severe pain in his right middle finger. History showed that the symptoms had been present for three years and he had made several attempts to seek medical attention. A sensitive, very painful mass was palpated under...

Loss of extensor tendon continuity at the distal interphalangeal joint (DIPJ) causes the joint to rest in an abnormally flexed position. This occurs with a laceration to the dorsum of the digit near the DIPJ. Mallet finger describes the condition in which the skin remains closed and the extensor tendon...

Structural deformities of the digits of the hand are common in patients with rheumatoid arthritis (RA). A swan-neck deformity, typically defined as proximal interphalangeal (PIP) joint hyperextension with concurrent distal interphalangeal (DIP) joint flexion, occurs in approximately 50% of patients with RA. However, swan-neck deformity is not unique to RA,...

Pollicization is the surgical creation of a thumb from a finger, usually the index finger. There are several techniques, but they have in common steps to shorten, rotate, and reposition muscles to achieve a functional and aesthetic result.

Closed rupture of the middle slip of the extensor hood of a finger is easily missed until the late appearance of a buttonhole deformity. Early diagnosis gives the best chance of satisfactory treatment, but Boyes' test becomes positive only at a late stage. A new test is described in which,...

Definition Finger reattachment (or replacement) is defined as reattachment of the part that has been completely amputated. Purpose Replantation refers to reattachment of a completely severed part, meaning there is no physical connection between the part that has been cut off and the person. Reattachment can be surgically performed for the finger and... Expert

This 11 year old boy developed clicking and locking of his index finger after a chemical (hydrofluoric acid) burn of the finger at the proximal phalanx level. This is an unusual situation in several respects. Locking flexor tendinitis is most common in adults, spontaneous, and involves the tendon in the...

OBJECTIVES: We evaluated patients who underwent surgery for glomus tumors of the finger. METHODS: During a 23-year period, 60 patients (48 females, 12 males; mean age 34.6 years; range 5 to 60 years) underwent surgery for glomus tumors of the finger. The patients were evaluated with respect to symptoms on...

Radiology case 436-3122 Clinical presentation: 30 year old man with a history of pain in the left middle finger, relieved by aspirin.
There is sclerosis of the proximal phalanx of the left middle finger. This takes the form of a peripheral mid-diaphyseal fairly well-defined 4mm. lucency and adjacent related cortical thickening.

Ectrodactyly-ectodermal dysplasia-cleft syndrome (EEC) is an autosomal dominant disorder characterized by the triad of ectrodactyly, ectodermal dysplasia, and facial clefting (Celli, Duijf, Hamel, et al. 1999). Other features noted in association with EEC include vesicoureteral reflux, recurrent urinary tract infections (Ramirez, Lammer, 2004), obstruction of the nasolacrimal duct (Peterson-Falzone, Hardin-Jones,...

The "delta bone" refers to a situation in which the middle bone in the finger is more of a triangular than a rectangular shape. This can occur with or without syndactyly. Although a delta bone results in a sideways curve of the finger, the joints on each end of the...

Feindel and Stratford (1958) were the first to use the term cubital tunnel. They emphasized that the ulnar nerve is compressed at the elbow because of anatomic peculiarities to that region. In 1898, Curtis performed the first published case of management for ulnar nerve neuropathy at the elbow, which consisted...

Reconstruction of an irreparably amputated thumb in multiple digit amputations using amputated fingers can considerably improve hand function and allows creation of a newly transplanted thumb with acceptable cosmetic and functional attributes. However, the surgery is challenging and rarely reported. We report six cases using this procedure in patients with...

In 1939, Kanavel, author of the landmark Infections of the Hand, observed, "In almost all cases of serious infection the difficulty is to make a correct diagnosis both as to the nature of the infection and the position of the pus." Specific infections covered in this article include paronychia, felon,...

Human fingernails, located on the dorsal aspect of the terminal 40% of the distal phalanx of each finger, are dynamic and physiologically important organs of the hand. Trauma to the fingertip and nail unit remains the most common of all hand injuries. The fingertip is one of the last anatomic...
