CC : เจ็บมือซ้ายมา 1 วันก่อนมารพ.
PI : 1 วันก่อนมารพ. มือซ้ายกระแทกกาแพงขณะกาลังจับไก่ มีอาการเจ็บมาก มือบวม
มากขึ้น ไม่มีแผลที่มือ กานิ้วไม่ได้เพราะเจ็บมาก จึงมารพ.

Investigation
Film Left hand AP, Oblique
Diagnosis
Close fracture 3rd and 4th shaft of Metacarpal
bone
Management
MO 4 mg IV stat
Close reduction
On short arm volar slab in flexion MCP 90˚c
left arm
On arm sling Left arm
Discharge นัด F/U 1wk พร้อม Film left hand
AP,oblique
Film after close reduction and slab
Review Fracture Metacarpal bone
Metacarpal bone fracture
divided into fractures of metacarpal head, neck, shaft,
base
treatment based on which metacarpal is involved and
location of fracture
acceptable angulation varies by location
no degree of malrotation is acceptable
Epidemiology
Incidence : metacarpal fractures account for 40% of all
hand injuries
Location : metacarpal neck is most common site of
fracture, fifth metacarpal is most commonly injured
Mechanism of injury
direct blow to hand or rotational injury with axial load
high energy injuries (ie. automobile) may result in
multiple fractures
Physical exam
inspect for open wounds and associated injuries
fight wounds over MCP joint are open until proven otherwise
extensor tendon can be lacerated and retracted
dorsal wounds over metacarpal fractures are almost always open
fractures
deformity indicates location
deformity at metacarpal base may indicate CMC dislocation
shortening can be assessed by comparing contralateral hand
malrotation assessed by lining up fingernail in partial flexion and full
flexion if possible, compare to contralateral side
Physical exam
motor examination
typically no motor deficits unless open wounds present
check integrity of flexor/extensor tendons in presence of open wounds
neurovascular examination
dorsal wounds may affect dorsal sensory branch of radial/ulnar nerve
volar wounds can involve digital nerves, test for radial and ulnar border
two-point discrimination on the injured digit before any
regional/hematoma block or attempted reduction
Film
AP
Oblique : เพื่อเลี่ยงการซ้อนกันของกระดูกในแต่ละนิ้ว
General Treatment
Nonoperative: immobilization
indications
must be stable pattern
no rotational deformity
acceptable angulation & shortening
General Treatment
Operative
Intra-articular fracture
Rotational malalignment of digit
Significantly displaced fracture
Multiple metacarpal fracture
Postoperative
Early motion
Remove pins/cast at 4 weeks
Treatment of Metacarpal shaft fracture
Goal : shortening < 5mm, Angulation < 20˚c, no
rotation
หากไม่ได้ตาม Goal  ORIF
Treatment : close reduction then immobilize MCP
joint in 90 degree flexion for 4 weeks
Treatment of Metacarpal neck fracture
M/C Little finger (Boxer’s fracture)
มักมี dorsal angulation เนื่องจากแรงดึงของ interosseous muscle
นิ้วก้อย accept angulation ได้40˚c
Mx : close reduction by Jahss’ Method (Flex MCP and
PIP joint 90˚c) และใช้นิ้วกดบริเวณ apex of angulation จากนั้น
immobilize MCP joint in flexion 90˚c

Editor's Notes

  1. Metacarpal head : The Brewerton view (metacarpophalangeal [MCP] joint flexed 65° with the dorsum of the proximal phalanx flat against the radiograph cassette and the beam angled 15° ulnar to radial) profiles the collateral recesses and is helpful for collateral ligament avulsion fractures
