Connaître les noms communs des fractures les + fréquentes
Début chap.42
Détailler le grade de Fracture de Gustillo et traitement/atb associés
Grades
Grade I: Wound less than 1 cm long, punctured from below
Grade II: Laceration 5 cm long; no contamination or crush; no excessive soft tissue loss, flaps, or avulsion
Grade III: Large laceration, associated contamination or crush; frequently includes a segmental fracture
IIIA: Involves extensive soft tissue stripping of bone
IIIB: Periosteal stripping has occurred
IIC: Major vascular injury present
Management
1.
Control hemorrhage in field with sterile pressure dressing after carefully removing gross debris (eg, wood, clothing, leaves).
2.
Splint without reduction, unless vascular compromise is present.
3.
Irrigate with saline, cover with saline-soaked sponges after arrival in the emergency department.
4.
Begin IV antibiotic prophylaxis, usually a first-generation cephalosporin for grade I, with the addition of an aminoglycoside for grades II and III. Ajout ampi ou PNC si blessure dans ferme (clostridium)
5.
Administration of tetanus prophylaxis, including tetanus immune globulin, for large crush wounds

Prise en charge subluxation/luxation IPP/IPD
IPD : rare, réduire, référer
IPP:
Dorsal and lateral dislocations should be immobilized in 20 to 30 degrees of flexion or with an extension block splint—dorsal splint allowing flexion but restricting extension—for 2 to 3 weeks, followed by active movement. Reduced volar dislocations should be splinted in full extension. Open or irreducible dislocations, unstable reductions, dislocations with volar plate avulsion and intraarticular fractures involving more than 30% of the joint surface should receive hand service referral.
Comment réduire subluxation dorsale MCP?
Hyperextension and longitudinal traction should be avoided because the volar plate of the MCP joint may become entrapped in the joint space. Rather, simple subluxed MCP joints should be reduced with the wrist in flexion, relaxing the flexor tendons, and applying direct dorsal pressure on the proximal phalanx. To stabilize, the hand should be splinted with 90 degrees of MCP joint flexion (see Fig 43.28). Hand service referral should be requested for complex dorsal and volar dislocations because both may require operative reduction for stabilization
Expliquer la lésion de stener
Associé à la lésion du ligament collatéral ulnaire du 1er MCP
Si lésion partielle - immobilisation spica 3 sem
Si lésion complète ou stener - immobilisation - référence

Prise en charge les lésion des tendons extenseurs selon les zones
Zone 1: mallet finger, immobilisation extension 6-8 sem, réparation si lésion ouverte, en chronique - déformation col de cygne ( par déplacement des bandes latérales vers l’aspect dorsal)
Zone 2: The central band inserts on the middle phalanx and the lateral bands extend to the base of the distal phalanx. Rarely, lacerations transecting all the tendons will produce a mallet deformity. Treatment options are similar to those for zone I injuries
Zone 3: cf autre question
Zone 4: réparation avec suture 5.0, rarement rétraction
Zone 5: lésion clenched fist ad preuve du contraire, exploration en SOP. Clavulin ou clinda + doxy/cipro/bactrim
Zone 6: réparation si facilement visible
Zone 7-8: référence en ortho/plastie

décrire la lésion des extenseurs zone 3
The Elson test may identify a central slip rupture; with the patient’s PIP joint in 90 degrees of flexion over the edge of a counter, the patient is asked to extend the middle phalanx actively. Weak extension with rigid DIP joint extension is suggestive of a central slip injury (Fig. 43. 37). Closed PIP joint injuries should be immobilized in extension, leaving the DIP joint free, with referral to a hand specialist
