Objective:
Determine predictive injury factors for wound complications in open pilon fractures (OTA/AO 43B and 43C).
Design:
Retrospective Case Series.
Setting:
Level I Trauma Center.
Patients/Participants:
A total of 61 open pilon fractures in 60 patients were evaluated after meeting inclusion and exclusion criteria.
Intervention:
The majority of injuries underwent a staged protocol with immediate antibiotics, debridement, irrigation and external fixation. Following soft tissue stabilization, internal fixation was performed and wound closure achieved in a coordinated fashion depending on the type of closure required.
Main Outcome Measurements:
Early amputation rate, 90-day major (wound dehiscence or deep infection requiring operative intervention) and minor (superficial infection) wound complications.
Results:
Four patients incurred early amputations, 11 had major wound complications and 5 had minor wound complications. An early amputation was more likely if they presented with an OTA Open Fracture Classification (OTA-OFC) Bone Loss Grade 3. A major wound complication was more likely if they presented with a fall from > 3 m, a multifragmentary articular surface, a segmental fibula fracture, or an OTA-OFC Contamination Grade 3. A multifragmentary articular surface was also predictive of developing any wound complication.
Conclusions:
Open pilon fractures are severe, limb-threatening injuries and are at risk for wound complications. Patients presenting with these injuries and a predictive factor should be counseled regarding the possibility of early limb loss or experiencing a wound complication that will require additional treatment.
Level Of Evidence:
Level III.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

01:24Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
