What is proximal tibiofibular joint?
What is proximal tibiofibular joint?
The proximal tibiofibular joint is a synovial joint that functions in dissipating lower leg torsional stresses and lateral tibial bending moments and in transmitting axial loads in weight-bearing [1]. The proximal tibiofibular joint is located between the lateral tibi al condyle and the fibular head.
What attaches to the proximal tibiofibular joint?
The PTFJ is the site of attachment of numerous structures which help stabilize the tibiofemoral joint. These include the fibular collateral ligament (FCL), the capsular arm of the short head of the biceps femoris, the fabellofibular ligament, the popliteo-fibular ligament, and the popliteus muscle.
What is proximal tibiofibular joint instability?
Instability of the proximal tibiofibular joint occurs when the ligaments which provide stability to this joint are injured. Because the joint is relatively inherently stable because of its bony anatomy when the knee is out straight, most cases of proximal tibiofibular joint instability occur when the knee is bent.
What classification is the proximal tibiofibular joint?
The proximal tibiofibular joint (PTFJ) is a plane type synovial joint. The primary function of the PTFJ is dissipation of torsional stresses applied at the ankle and the lateral tibial bending moments besides a very significant tensile, rather than compressive weight bearing.
What is the function of the tibiofibular joint?
As a plane synovial joint, the superior tibiofibular joint allows slight gliding movements. More specifically, this joint allows the accessory movement of anteroposterior gliding of the fibula against the tibia. These movements occur in a superior-inferior direction, and range to only a few degrees.
Which of the following describe the superior tibiofibular joint?
The superior tibiofibular joint is a plane synovial joint, while the inferior one is a syndesmosis (fibrous joint). These joints allow no active movements. They do, however, permit a small range of gliding movements that accomodate the movements of the ankle joint.
What is Tibiofibular pain?
What are the symptoms of a superior tibiofibular joint injury? Pain is felt on the outside of the leg, just below the knee if the superior tibiofibular joint is injured. Pain is usually worsened by activities that require rotation of the lower leg, such as pivoting or changing direction whilst running.
Where is the tibiofibular ligament?
The anterior ligament of the lateral malleolus (anterior tibiofibular ligament or anterior inferior ligament) is a flat, trapezoidal band of fibers, broader below than above, which extends obliquely downward and lateralward between the adjacent margins of the tibia and fibula, on the front aspect of the syndesmosis.
What type of synovial joint is the superior tibiofibular joint?
plane type
The superior tibiofibular joint is a plane type of synovial joint, which allows the involved bones to glide over one another to create movement. This joint is located between the flat articular facet on the fibular head and a similar articular facet situated posterolaterally on the lateral tibial condyle.
What are tibiofibular joints?
The tibiofibular joints are a set of articulations that unite the tibia and fibula. These two bones of the leg are connected via three junctions; The superior (proximal) tibiofibular joint – between the superior ends of tibia and fibula.
Where is the proximal tibiofibular joint located?
The proximal tibiofibular joint is located between the lateral tibial plateau of the tibia, and the head of the fibula. Typically, the proximal tibiofibular joint is injured in a fall when the ankle is plantar-flexed, with the stress being brought through the fibula,…
How is proximal tibiofibular subluxation related to lateral knee pain?
Proximal tibiofibular subluxation relationship to lateral knee pain: A review of proximal tibiofibular joint pathologies. Treatment for patients with acute PTFJ dislocation consists of urgent reduction, followed by immobilization in extension and restricted weight bearing. Instability of the proximal tibiofibular joint.
What is the prognosis of tibiofibular joint replacement surgery?
Most patients are cleared to begin full activities between four to six months postoperatively, assuming they have adequate restoration of proximal tibiofibular joint stability, pain relief, and return of strength, agility and endurance.
How is the diagnosis of tibiofibular joint instability confirmed?
In acute cases, it may be difficult to make the patient relax sufficiently to be able to examine for proximal tibiofibular joint instability, but usually having the knee flexed to 90 degrees and trying to perform an anterolateral subluxation maneuver of the proximal tibiofibular joint is sufficient to confirm this diagnosis.
