What is tibiofibular synostosis?

Tibiofibular synostosis is a rare condition of union between tibia and fibula. Etiologically, it may be congenital, acquired (traumatic, iatrogenic, therapeutic types) or idiopathic [8].

Which ankle movement is restricted following tibiofibular synostosis?

Therefore, synostosis between the tibia and fibula will be associated with a restricted fibular rotation and translation and accordingly may be complicated by a painful decreased ankle motion, usually during weight bearing and push off.

What does the distal tibiofibular joint do?

It strongly connects the bones and it is the principal stabilizer of this joint. The anterior and posterior tibiofibular ligaments extend between the anterior and posterior surfaces of the tibia and fibula, respectively.

What movement occurs at the distal tibiofibular joint?

During ankle plantar flexion and dorsiflexion, some movement normally occurs at the distal tibiofibular syndesmosis. When the foot is moved from a plantar-flexed position to a dorsiflexed position, the joint permits approximately 1 to 2 mm of widening at the mortise.

What is tibiofibular syndesmosis?

The tibiofibular syndesmosis is a complex fibrous joint composed of multiple ligaments and a broad fibrous interosseous membrane that spans between the tibia and fibula throughout the length of both bones.

Are the tibia and fibula fused together?

In many mammals, such as the horse and the rabbit, the fibula is fused for part of its length with the tibia. Fractures of the fibula usually are associated with an ankle injury, though they can occur in isolation (without ankle involvement) or in combination with fractures of the tibia (e.g., in severe injuries).

How long does syndesmosis take to heal?

Evidence suggests that syndesmosis sprains typically require 6 to 8 weeks for recovery, but this is variable. Chronic pain, instability, and functional limitations are common after syndesmosis sprains.

What type of joint is the distal tibiofibular?

syndesmotic joint
A syndesmosis is a complex fibrous joint between two bones and connected by ligaments and a strong membrane with slightly movement allowed. The distal tibiofibular syndesmosis/inferior tibiofibular joint is a syndesmotic joint.

What does ankle mortise mean?

When the foot is plantar flexed, the ankle joint also allows some movements of side to side gliding, rotation, adduction, and abduction. The bony arch formed by the tibial plafond and the two malleoli is referred to as the ankle “mortise” (or talar mortise). The mortise is a rectangular socket.

What is the function of syndesmosis?

The function of syndesmosis ligament complex: Provide strong stabilization and dynamic support to the ankle mortise. Maintain the integrity between the distal tibia and fibula. Resist forces (axial, rotational, and translational) that attempt to separate the two bones.

How long does it take to walk after a broken tibia and fibula?

Recovery from a tibia-fibula fracture typically takes about three to six months. Your child may be able to heal faster by resting and not putting too much weight on their leg until the bone has healed.

How do you sleep with a broken tibia and fibula?

Invest in a specialized pillow, like a body pillow, for elevation—keeping the broken bone above your heart prevents blood from pooling and causing swelling. Try sleeping on your back first while propped up on a few pillows. If that doesn’t work, slowly adjust yourself to a side position if possible.

What causes synostosis of the distal tibiofibular joint?

Synostosis of the distal tibiofibular joint is usually acquired but it may also be idiopathic or congenital. The latter has been noted in patients suffering from the syndrome of multiple hereditary exostoses, fibrodysplasia ossificans progressive, flourosis, scurvy and hemophilia.

Can a synostosis of the tibia cause ankle pain?

These lesions may potentially lead to ankle pain, since the synostosis interferes with the normal motion that occurs between the tibia and fibula during weight-bearing [1]. Synostosis of the proximal tibiofibular joint has been reported in both children and adults.

What kind of condition is Congenital radioulnar synostosis?

Congenital radioulnar synostosis is a rare condition in which there is an abnormal connection (synostosis) of the radius and ulna (bones in the forearm) at birth.

Can a fractured synostosis cause recurrent compartment syndrome?

A fractured synostosis and a recurrent compartment syndrome after a fractured synostosis have been reported as rare complications of the lesion [19 -28]. The distal tibiofibular joint is a syndesmosis formed by two bones and four ligaments.
