What is a disadvantage of open reduction and internal fixation (ORIF) of a fracture compared to closed reduction?

Choice A reason: Equal weights on each side are appropriate in skeletal traction, ensuring balanced force to maintain bone alignment. This finding supports the traction’s purpose of stabilizing the fracture without causing uneven stress on the bone or soft tissues. No correction is needed, as this is a correct setup.

Choice B reason: Securely attached ropes to pins are essential in skeletal traction to transmit consistent force to the bone. Loose attachments could disrupt alignment or cause pin site complications like infection. This finding is correct and does not require correction, as it ensures effective traction and patient safety.

Choice C reason: Weights resting against the bed negate the traction’s pulling force, failing to maintain bone alignment. Weights must hang freely to apply continuous tension, counteracting muscle spasms and stabilizing the fracture. This finding requires correction to restore effective traction and prevent malunion or delayed healing.

Choice D reason: Ropes centered in wheel grooves ensure smooth movement and consistent traction force without fraying or misalignment. This is a correct setup, as misaligned ropes could reduce traction effectiveness or cause mechanical issues. No correction is needed, as this supports proper traction mechanics.

Choice A reason: Assessing tetanus immunization status is critical for an open fracture, as wounds exposed to soil or debris risk Clostridium tetani infection. Tetanus prophylaxis (vaccine or immunoglobulin) prevents lockjaw and neuromuscular complications. This ensures timely immunization, reducing life-threatening infection risks in contaminated wounds like those from bicycle accidents.

Choice B reason: Determining exposure to dirt or gravel is essential, as open fractures are prone to bacterial contamination (e.g., Staphylococcus aureus or Pseudomonas). Contaminated wounds require urgent irrigation, debridement, and antibiotics. This assessment guides infection prevention, ensuring prompt surgical and antimicrobial interventions to minimize osteomyelitis or sepsis risks in open tibial fractures.

Choice C reason: Previous leg injuries are relevant for overall musculoskeletal history but not immediate for open fracture management. Current wound contamination and infection risk take precedence. Focusing on past injuries delays critical interventions like tetanus prophylaxis or debridement, potentially worsening outcomes in acute open fractures from bicycle accidents.

Choice D reason: Recent antibiotic use is less urgent than contamination or tetanus status in open fractures. While it may inform antibiotic resistance, it’s not a primary assessment focus. Prioritizing this risks delaying wound cleaning and prophylaxis, increasing infection risks like cellulitis or osteomyelitis in contaminated open tibial fractures.
