There are five kinds of ring orthopedic External Fixation mainly used for tibial and femoral fractures.
1. Ring fixator for tibial & femur fracture 2. 2/3 ring fixator for tibial & femur fracture 3. Bone lengthening ring fixator for tibial & femur fracture and bone lengthening 4. Ring fixator for tibial & femur fracture 5. Ring fixator for tibial & femur fracture
For example,patients with proximal tibial fractures who cannot walk and have severe soft tissue injuries can be treated with external fixation using a ring frame.The ring External Fixator has the advantages of short operation time,simple operation and minimally invasive operation.It does not affect the blood supply of the fracture end and does not require secondary surgery.The dynamic design of the controlled external fixator can be used to micromove and promote fracture healing.The orthopedic Bone Screw is designed with conical thread,the tighter the screw is,the fixation is reliable,and it is suitable for the correction of various deformities.

Surgical orthopedic surgery
1.The patient was placed in the supine position, using a radiolucent or fracture table.
2.A small incision is usually used to reduce the articular surface.The incision should be selected according to the fracture, usually including:anterolateral or anteromedial incision,Medial or posteromedial incision.
3.The annular external fixator should be preinstalled according to the preoperative image.In general,2pcs proximal and distal rings are included.
4.Reduction of the articular surface through one or more approaches.The meniscus was observed for tear and retracted to expose the articular surface.The aim is to obtain as stable internal fixation of articular fractures as possible.
5.The intra-articular hematoma and unfixable fracture debris were cleaned,and the fracture fragments were temporarily fixed with reduction forceps or Kirschner wire after reduction.The fracture reduction was observed under direct vision and fluoroscopy, and then the smaller fracture fragments were fixed with screws and fine needles with threads.
6.The fixation material is parallel to and as close as possible to the articular surface,and does not penetrate the articular surface, leaving enough space for the circular external fixator.The injured meniscus was removed or repaired,depending on the location.The meniscus was sutured to the medial and lateral collateral ligaments using nonabsorbable sutures.
7.The incision was closed first, and then the annular external fixator was applied.The proximal fracture was fixed with an external fixation ring.The distal external fixation ring was fixed to the femoral shaft. Install the external fixator.
8..Bone defects can be managed in a variety of ways:Use of allogenic or autogenous bone grafts during open reduction and internal fixation.Artificial bone can also be injected locally.
