Phalangeal fractures are more common, which can occur in the proximal, middle or distal section, section shaft fracture nearly the most common. It is usually caused by direct violence. Each hand has 14 phalanx: into the far section, and the proximal phalanx of the thumb only two phalanx.
 

Phalangeal fractures can be divided into the following types:
 

1. The proximal phalanx fractures: volar angulation projections (due interosseous muscle and lumbrical traction).
 

2. phalangeal neck fractures: volar projection angled, distal to the dorsal rotation of 90 degrees (referring to the central portion of the extensor stretch).
 

3. phalanx fracture:
 

(1) Bottom groups phalanx fracture, the fracture line in superficial flexor tendon proximal Reattachment point, due to superficial flexor tendon stretch, fracture distal palmar flexion, the fracture into the dorsal horn.
 

(2) shallow fracture of the distal tendon dead, nearly ends allegedly led to the superficial flexor tendon palmar fracture volar angulation.
 

4. distal phalanx fracture: more direct violence injury, such as extrusion, injured, by transverse or comminuted fracture, minimal displacement.
 

5. the bottom avulsion fracture of the distal phalanx: mallet finger deformity, can not take the initiative straight.

 

Conservative treatment
 

1. finger shaft fractures:
 

Reset: correct volar angulation.
 

Fixation methods: finger flexion.
 

Fixed time: 3 weeks.
 

2. phalangeal neck fractures
 

Reset: increase angled, reflexed practices.
 

Fixation: the finger shaft fractures with.
 

Fixed time: 3 weeks.
 

3. The fracture of the distal phalanx avulsion bottom:
 

Reset: the proximal interphalangeal joint flexion, distal interphalangeal joint hyperextension.
 

Fixation: the more difficult.
 

Fixed time: 6 weeks.
 

Surgical treatment
 

Indications: open fractures, manipulative failure and nonunion
