Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

3.1K
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...

Fractures: Bone Repair

3.2K
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: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

2.4K
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...

Ankle Joint01:10

Ankle Joint

1.5K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Knee Joint01:23

Knee Joint

1.7K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Muscles that Move the Leg01:23

Muscles that Move the Leg

1.6K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

Summary
This summary is machine-generated.

Proximal tibiofibular fracture and dislocation (PTFD) is a common indicator of severe knee trauma with vascular injury. This condition, often missed, presents a high amputation risk, underscoring the need for prompt diagnosis in trauma cases.

Area of Science:

  • Orthopedic Surgery
  • Trauma Surgery
  • Vascular Surgery

Background:

  • Traumatic proximal tibiofibular fracture and dislocation (PTFD) is an understudied injury, frequently missed in clinical settings.
  • PTFD signifies severe knee trauma and is often associated with vascular compromise.
  • Understanding PTFD's incidence and impact in vascularly injured knees is crucial for patient outcomes.

Purpose of the Study:

  • To retrospectively determine the incidence of PTFD in patients with traumatic knee injuries and associated vascular damage.
  • To evaluate the clinical impact and outcomes of PTFD in this patient cohort.

Main Methods:

  • Retrospective analysis of patients with knee trauma and vascular injury from January 2022 to October 2023.
  • Radiographic (X-ray) and CT scan review to identify PTFD.
  • Comparative analysis between patients with PTFD and those without.

Main Results:

  • The incidence of PTFD in traumatic knees with vascular injury was 39.3% (11/28 limbs).
  • The PTFD group showed a significantly higher rate of open injuries (10/11) compared to the non-PTFD group (7/17).
  • The amputation rate in the PTFD group was 40% (4/10 limbs), compared to 23.5% (4/17 limbs) in the non-PTFD group, though not statistically significant.

Conclusions:

  • PTFD is frequently overlooked in traumatized knees with vascular injury, despite its high incidence.
  • The presence of PTFD may indicate a more severe injury pattern, including a higher likelihood of open fractures.
  • While not statistically significant in this study, the 40% amputation rate in the PTFD group highlights its potential severity and the need for vigilant management.
