When should syndesmosis screws be removed?
Some studies have shown that the removal of syndesmotic screws can be performed about 3 to 4 months after surgery, especially when patients have discomfort or limitation of ankle dorsiflexion due to these screws.
Where do you put the syndesmosis screw?
Fixation of the syndesmotic complex Drill a 2.5 mm hole through the fibula and the lateral cortex of the tibia, just proximal to the inferior tibiofibular joint, 30 degrees from posterior to anterior, parallel to the tibial plafond, with the ankle joint in neutral position.
Do we need to remove syndesmotic screw?
Conclusion: Removal of syndesmotic screws is advisable mainly in cases of patient complaints related to the other implanted perimalleolar hardware or malreduction of the syndesmosis after at least 8 weeks postoperatively. Broken or loose screws should not be removed routinely unless causing symptoms.
What are syndesmotic screws used for?
A syndesmotic screw designed to replace the inferior tibiofibular articulation that fix the tibia and fibula together at the lower joint, is 5–6 cm long and made of a stainless, solid metal. The screw may inhibit normal movement of the bones and, thereby, the corresponding joint(s).
What happens if a syndesmotic screw breaks?
Conclusion: Syndesmotic screw breakage may be more problematic than previously described. Intraosseous breakage was associated with higher rates of implant removal secondary to pain in this study. Placement of screws 20 mm or higher from the tibiotalar joint may decrease risk of intraosseous breakage.
What is a syndesmosis repair?
The syndesmosis cannot be simply repaired by suturing ligaments together, so instead, the two bones of the leg are stabilized together to allow the syndesmosis to heal in the proper alignment – either by using one or two screws that span the fibula and tibia completely (called syndesmosis screws), or alternatively, by …
How do you prevent ankle syndesmosis?
Recently, the most common operative method used to reduce the syndesmosis has involved placement of a pointed reduction clamp around the distal tibia and fibula to maintain reduction of the syndesmosis with fixation (9–13).
Can you walk after syndesmosis screw removal?
After surgery, patients were allowed to walk with protected weight-bearing as early as possible. A full range of motion of the knee and toes was encouraged. Patients were followed up at the outpatient department at six weeks, three months, one year and whenever necessary.
What is the tibiofibular syndesmosis?
The tibiofibular syndesmosis is a fibrous joint essential for ankle stability, whence the classical comparison with a mortise. Syndesmosis lesions are quite frequent in ankle trauma. This is a key element in ankle stability and lesions may cause pain or instability and, in the longer term, osteoarthritis.
Does syndesmosis require surgery?
For unstable ankle syndesmosis injuries (Grades 2 and 3), surgery will be required to restore ankle stability. This is usually achieved by inserting pins to hold the tibia and fibula together to prevent widening of these bones during weight-bearing activities.
What is distal tibiofibular syndesmosis?
A syndesmosis is defined as a fibrous joint in which two adjacent bones are linked by a strong membrane or ligaments. This definition also applies for the distal tibiofibular syndesmosis, which is a syndesmotic joint formed by two bones and four ligaments.
What is the mortise of the ankle?
A majority of the articular surface is formed by the horizontal portion of the distal tibia (the tibial plafond) which extends parallel to the dome of the talus; taken with the medial and lateral malleoli, it forms a rectangular socket known as the ankle mortise.
Does tightrope improve the reduction of tibiofibular syndesmosis?
Improved Reduction of the Tibiofibular Syndesmosis With TightRope Compared With Screw Fixation: Results of a Randomized Controlled Study Therapeutic Level I.
Should syndesmotic screw removal be performed for fractures with interruption of syndesmosis?
Discussion:Fractures with interruption of syndesmosis are lesions that, if not well treated, are complicated by joint stiffness, residual pain and post-traumatic osteoarthritis. Syndesmotic screw removal is not routinely performed, thus accepting the risk of rupture but avoiding a new surgery.
What happens to the fibula when the syndesmosis is disrupted?
It may also be injured in some transsyndesmotic fractures. If the syndesmosis is disrupted, the fibula needs to be held in the correct position in relation to the tibia whilst the ligaments heal. There are differences of opinions between surgeons as to:
Should syndesmosis be fixed in Weber Type B and C fractures?
Conclusion: In ankle fractures, if diastasis of distal tibiofibular joint is present, syndesmosis should be fixed for both Weber Type B and C fractures. The most important predictor of good clinical outcome is accurate reduction of the syndesmosis.
