The‍‌‍‍‌‍‌‍‍‌ bone lengthening ring fixator is a kind of external fixation device, very advanced and specialized; in fact, each segment of the ring can be rotated independently. It also allows controlled adjustments during the healing without recurrent surgeries. Surgeons usually offer it in the treatment of limb deformities, complex fractures, bone defects, and bone lengthening procedures.

The ring fixator is one of the foreign devices that can achieve the same healing environment as very good quality internal fixation. The bone lengthening ring fixator mainly consists of a ring, rod, clamps, fixation pins, and tension wire. During treatment, the surgeon can gradually adjust the device according to clinical needs to achieve compression, traction, alignment correction, or bone transport. The ring structure helps maintain stable alignment during recovery, and surgeons can make controlled adjustments without repeating major surgeries.

An ilizarov external fixator is the collective term for a set of devices that are located outside the limb and connected to the bone through pins and wires. The bone lengthening ring fixator can be used in combination with other treatment techniques to treat the most complex trauma cases of the lower limb.

This ilizarov external fixator has significantly facilitated the management of cases with soft tissue injury, open fracture, and fracture associated with infection, conditions in which internal fixation is generally contraindicated. In addition to providing reliable mechanical stability, this external fixation system is designed to minimize damage to the surrounding tissues.

The bone lengthening ring fixator is made up of several components, with each having its own function. Ring: supports and stabilizes the bone during limb lengthening. Rods: used for assembly of the ring fixator frame or the mounting of the fixator piece. Clamps: secures the rods and rings together.Fixation pins: allow the ring to be secured to the bone for stability. Tension wire:used along with pins for fixation.

Apart from being an effective mechanical stabilization tool, the ilizarov external fixator frame can also be used as a treatment method for nonunion and malunion, bone transport, or even as a temporary measure in case of open fractures. Moreover, ilizarov external fixator allow more freedom of movement compared to other fixation methods since the treatment can be externally manipulated during the healing phase.
