Insights

Flexible nails (FNs) offer advantages over submuscular plates (SMPs) for pediatric femur fractures, reducing operative time and blood loss. FNs also led to shorter hospital stays, making them a potentially more efficient treatment option.

Area of Science:

  • Orthopedic surgery
  • Pediatric trauma
  • Biomedical engineering

Background:

  • Diaphyseal femur fractures are common in children.
  • Submuscular plates (SMPs) and flexible nails (FNs) are surgical options.
  • Outcomes of these methods require comparative analysis.

Purpose of the Study:

  • To compare patient characteristics, operative time, blood loss, hospital stay, and complications.
  • The study focuses on pediatric diaphyseal femur fractures.
  • Comparison is between submuscular plates (SMPs) and flexible nails (FNs).

Main Methods:

  • Retrospective review of 58 children with diaphyseal femur fractures.
  • Treatment groups: 30 with SMPs and 28 with FNs (2005-2017).
  • Exclusion criteria: pathological fractures and musculoskeletal comorbidities.

Main Results:

  • FNs associated with significantly shorter operative time for insertion and removal compared to SMPs.
  • FNs demonstrated less estimated blood loss (EBL) during insertion (p < 0.001).
  • The FN group experienced a shorter length of hospital stay (LOS) post-insertion (p = 0.032).

Conclusions:

  • Flexible nails (FNs) are associated with reduced operative time and EBL for insertion.
  • FNs also correlate with a shorter post-insertion LOS in pediatric diaphyseal femur fractures.
  • Both methods had comparable rates of surgical site infections; implant irritation was more common with FNs.

Accessory Structures of the Skin: Nails

Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
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...

¹H NMR of Conformationally Flexible Molecules: Temporal Resolution

At room temperature, the chair conformer of cyclohexane undergoes rapid ring flipping between two equivalent chair conformers at a rate of approximately 105 times per second. These two chair conformers are in equilibrium. The rapid ring flipping results in the interconversion of the axial proton to an equatorial proton and an equatorial to the axial proton. Such interconversions are too rapid and cannot be detected on the NMR timescale. Hence, the NMR spectrometer cannot distinguish between the...

Column Efficiency: Plate Theory01:10

Column Efficiency: Plate Theory

Band broadening in a chromatography column is measured by its efficiency. This is determined by the number of theoretical plates (N). Theoretical plate theory states that a separation column consists of a continuous series of imaginary plates where solute equilibration occurs between stationary and mobile phases.
A higher number of theoretical plates signifies better column efficiency and improved separation capabilities. Plate height affects bandwidth and separation quality; it is inversely...

Electric Field of Parallel Conducting Plates01:16

Electric Field of Parallel Conducting Plates

Gauss' law relates the electric flux through a closed surface to the net charge enclosed by that surface. Gauss's law can be applied to find the electric field and the charge enclosed in a region depending on its charge distribution.
Consider a cross-section of a thin, infinite conducting plate having a positive charge. For such a large thin plate, as the thickness of the plate tends to zero, the positive charges lie on the plate's two large faces. Without an external electric field, the...
