Fractures: Bone Repair01:27

Fractures: Bone Repair

5.0K
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...

Bones of the Lower Limb: Tibia and Fibula

8.8K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Area of Science:

  • Orthopedics
  • Podiatry
  • Surgical Complications

Background:

  • Intramedullary fixation of tibia fractures can lead to complications.
  • Checkrein deformity is a known complication, but isolated flexor digitorum longus (FDL) involvement is rare.
  • Post-traumatic adhesions can impair tendon function.

Purpose of the Study:

  • To report a case of isolated FDL checkrein deformity after tibial fracture fixation.
  • To describe the surgical management and outcome of this rare complication.
  • To enhance understanding of postoperative tibial fracture complications.

Main Methods:

  • A 36-year-old female patient with claw toe deformity post-tibia fracture surgery.
  • Diagnostic assessment revealing adhesions between FDL and posterior tibial tendons.
  • Surgical lysis of adhesions performed.

Main Results:

  • Successful surgical release of FDL tendon adhesions.
  • Complete resolution of claw toe deformity and symptoms.
  • Restoration of normal toe function at 1-year follow-up.

Conclusions:

  • Isolated FDL checkrein deformity is a rare but treatable complication of tibial fracture fixation.
  • Surgical lysis of adhesions is an effective treatment.
  • This case expands knowledge on the spectrum of postoperative tibial fracture complications.
