Plate Complications

Plate Complications

  • Vast majority of complications are implant

related

– irritation or failure of the plate being consistently reported on in almost every study,

  • n average ranging from 9 to 64%
  • “We conclude, based on the figures of plate

debridement, removal or revision, that the incidence of major complications is high, ranging up to 64%”

Infection after Plate Fixation

  • Reports range from 0.4% - 7.8%
  • Bostman (1997):
  • – 5 deep, 3 superficial

– 7.8%

  • Liu, et al (2008):

– 7 of 142 – Average time to presentation: 28 days – 4.9%

Vascular Injury

  • Vascular

injury can

the proximity

subclavian vessels to the medial clavicle

Intramedullary Fixation

  • IM fixation is not a new concept

Intramedullary fixation with beef bone (Brockway, JBJS, 1930)

slide-14
SLIDE 14

Types of IM fixation

  • Flexible

–Titanium elastic nail

  • Rigid

–Screws –Rockwood pin

  • Hybrid

–Arthrex CRx

slide-15
SLIDE 15

Intramedullary Fixation

  • Minimizes soft tissue dissection
  • Preservation of periosteal blood supply
  • Callus healing – faster and observable
  • Better resistance to repetitive bending
  • Ease of reduction

– “If it’s IM – It’s anatomic!”

  • Minimal stress shielding

– load sharing not sparing

  • Ease of hardware removal
  • Cosmetic incisions
  • Outpatient procedure

Results

  • With the exception of the IM Removal group, all

specimens failed significantly lower than the intact specimens.

Problems with IM Fixation

  • Painful, prominent hardware
  • #1 problem
  • Migration – smooth pins
  • Lack of length and rotational

control

  • Static distraction (fully treaded

pins, Herbert type screws)

“intramedullary pin fixation is the optimum treatment method for displaced midshaft clavicle fracture because of the low probabilities

  • f nonunion and infection”

“Major re-intervention and re-fracture after implant removal occurred more frequently after plate fixation of non-comminuted, displaced midshaft clavicle fractures.”

  • “Our results suggest that

intramedullary nailing and plating provide equivalent long-term functional outcomes; however, plating may lead to a higher risk of treatment failure and nonoperative complications.”
