Attachment Rupture of the Long Extensor Tendon (Mallet Finger, Mallet Thumb)

The extensor tendon of the finger is attached to the terminal phalanx (distal end of the finger). Disruption of the extensor tendon at this insertion (mallet finger) is one of the most common tendon injuries in sports. It is especially common in ball-handling sports. The usual mechanism of injury is that of a forceful bending […]

Dislocation of PIP Joint

Dislocation of the PIP joint is a common injury which often affects team handball, basketball and volleyball players, and cricketers. In 80% of cases it is the little finger that is damaged. The most common mechanism of injury is axial loading and hyperextension of the joint causing dorsal dislocation (dislocation upwards and backwards). The dorsal […]

Hand Injuries

The hand is one of the most common sites of injury during athletic competition. The palm consists of five metacarpal bones, one for each digit. The metacarpals in the middle of the hand have very little motion and provide a stable palm, while the little finger and especially the thumb have significantly more motion to […]

Rugby Finger

SYMPTOMS

There is localised exercise-induced pain and inability to flex the DIP or PIP joint of the third finger.

AETIOLOGY

These symptoms are caused by rupture of the volar plate with or without avulsion of a bony fragment or the flexor tendon insertion. It occurs when the finger is hyper-extended by force during […]

Extensor Tendon Laceration

Basics Description Extensor tendon lacerations are common because of the superficial location of the extensor tendons on the back of the hand. Tendon disruption often is indicated by a change in the posture of the hand or fingers. The most distal injury, at the DIP joint, shows a mallet-type of deformity. An injury over […]

Dupuytren Contracture

Basics Description Dupuytren contracture is a proliferative disorder of subcutaneous palmar fibrous tissue (fascia) that occurs in the form of nodules and cords and results in contractures of the finger joints. It occurs typically in men in the 5th to 7th decades. Younger patients are more likely to have rapid progression of disease with […]

Clinodactyly

Basics Description

Clinodactyly presents as a painless bent finger with angulation in a radial or ulnar direction . It is most commonly the little finger bent in a radial direction. Most often, the finger has a short, delta-shaped middle phalanx. This condition may be associated with mental retardation, especially when clinodactyly is severe. Synonym: Bent […]

Claw Toes

Basics Description The term claw toes describes a hyperextension deformity of the MTP joint of the lesser toes with flexion deformity of the PIP joint . General Prevention Use of appropriate shoe wear (wide shoes with a high toe box) can prevent the development of claw toes in many cases. Epidemiology Incidence Increases with […]

A Patient’s Guide to Swan Neck Deformity of the Finger

Introduction

Normal finger position and movement occur from the balanced actions of many important structures. Ligaments support the finger joints. Muscles hold and move the fingers. Tendons help control the fine motion of each finger joint. Disease or injury can disturb the balance in these structures, altering normal finger alignment and function. The result may […]

A Patient’s Guide to PIP Joint Injuries of the Finger

Introduction

We use our hands constantly, placing them in harm’s way continuously. Injuries to the finger joints are common and usually heal without significant problems. Some injuries are more serious and may develop problems if not treated carefully. One such injury is a sprain of the proximal interphalangeal joint, or PIP joint, of the finger. […]
