Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this research, a new bone harvesting technique is introduced in order to find an iliac crest bone harvesting method for patients with less trauma, less postoperative pain in donor sites, and lower incidence of postoperative complications, so as to get ideal bone grafting materials at a small cost, enhance the effect of osteogenesis repair on bone defect or fusion site, and improve the operation quality.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Based on the domestic and foreign research on minimally invasive bone harvesting, we have developed a disposable battery-powered bone harvesting device that can be used for milling bone tissues. Using this disposable battery-powered bone harvesting device, cancellous bone milling can be performed in a small bone hole with a diameter of 7.5 mm. The morselized bone or bone chips it milled can be used for bone fusion at the desired site. The technique adopts patented milling tool bit and electric drive, with high operation efficiency, so the surgery can be completed very quickly. The bone trauma in the operation can be significantly reduced and the pain in the donor site can be greatly alleviating. Moreover, the technique can obviously reduce the duration of bone harvesting and the cost of operating room. In addition, significant reductions in postoperative pain will also be helpful to a range of clinical advantages and benefits, such as the average hospitalization days, and will be expected to benefit significantly in patients undergoing autologous bone harvesting.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Minimally invasive bone harvesting surgery

1. .Applying routine approach in iliac crest bone harvesting surgery, make a 4cm long incision before or after the iliac crest, slice skin and subcutaneous tissue by layer., exposing the iliac crest ridge, outer plate and part of the iliac crest bone.
2. Use the cortical bone opening device to open two bone holes with a diameter of 7.5 mm side by side in the iliac bone cortex ,place disposable battery-powered bone harvesting device for iliac crest bone harvesting operations.
3. The direction of the tool bit should be parallel to the outer iliac plate, to avoid penetration of inner iliac layer, and avoid the injury to iliac blood vessels, nerves or internal organs.
4. .Scrap and collect the cancellous bone by tool bit during operation.
5. . After collecting sufficient amount of cancellous bone, turn off the power, screw out the cabin, and pour out the cancellous bone.
6. . Suturing the iliac crest periosteum and deep fascia, closing the incision layer by layer, no drainage.

Intervention Type PROCEDURE

Minimally invasive bone harvesting surgery

Traditional iliac crest bone harvesting surgery

1. .Applying routine approach in iliac crest bone harvesting surgery, make a 4cm long incision before or after the iliac crest, slice skin and subcutaneous tissue by layer., exposing the iliac crest ridge, outer plate and part of the iliac crest bone.
2. Use a bone chisel to open a lid on the iliac crest ridge cortex ,open the cover length at 3cm.
3. Lift the iliac crest ridge cortex plate cover, use bone knife and scraper to harvest bone in the iliac bone marrow cavity.
4. Avoid violence when using bone knives and scrapers, to avoid penetration of inner iliac layer, and avoid the injury to iliac blood vessels, nerves or internal organs.
5. After collecting sufficient amount of cancellous bone, suturing the iliac crest periosteum and deep fascia, closing the incision layer by layer, no drainage
