Abstract:
The application value of Masquelet induced membrane technique for the treatment of rat chronic osteomyelitis was explored. A total of 180 male Sprague-Dawley (SD) rats were randomly divided into sham operation group (control group), chronic osteomyelitis model group (model group) and Masquelet induced membrane therapy + chronic osteomyelitis model group (observation group); 60 rats in each group. A rat model of traumatic osteomyelitis was established using a modified blunt trauma method in model and observation group. All rats in observation group were treated with membrane induction technology while in the control group they were not. Postoperative complications, bone healing time and functional status of the affected limbs were recorded. After surgery, no obvious perioperative complications occurred in most of the rats, except that 5 rats experienced partial necrosis at the edge of the flap, and 3 experienced superficial infection around the incision site in the ilium. Primary bone healing was achieved in 50 rats with an average healing time of 15 weeks. Among them, 38 rats restored weight-bearing function after 20 weeks. Seven rats experienced infection after surgery, but complete bone healing was achieved after treatment with induced membrane technique again. Following treatment with induced membrane technique, the rat body weight, body temperature and the number of bacteria in the wound decreased over time. In conclusion, Masquelet induced membrane technique is effective for the treatment of large bone defects in rats after traumatic osteomyelitis. This technique significantly shortens the treatment cycle. The surgical procedure is simple, and the incidence of postoperative complications is low.
Insights
The Masquelet induced membrane technique effectively treats chronic osteomyelitis in rats with large bone defects, showing promising bone healing and functional recovery. This method offers a simple surgical procedure with a low complication rate.
Area of Science:
- Orthopedics
- Regenerative Medicine
- Surgical Innovation
Background:
- Chronic osteomyelitis presents a significant challenge in orthopedic surgery, often requiring extensive treatment for large bone defects.
- Current treatment modalities can be lengthy and associated with high complication rates.
Purpose of the Study:
- To evaluate the efficacy of the Masquelet induced membrane technique in treating chronic osteomyelitis with large bone defects in a rat model.
- To assess bone healing time, functional recovery, and postoperative complications associated with this technique.
Main Methods:
- A rat model of traumatic osteomyelitis was established in 180 Sprague-Dawley rats.
- Rats were divided into control, model, and Masquelet induced membrane therapy groups.
- The Masquelet technique involved membrane induction followed by bone graft implantation.
Main Results:
- The Masquelet technique demonstrated effective bone healing, with an average healing time of 15 weeks.
- 38 out of 50 rats regained weight-bearing function within 20 weeks.
- Postoperative complications were minimal, and recurrent infections were successfully treated with repeat application of the technique.
Conclusions:
- The Masquelet induced membrane technique is a viable and effective treatment for large bone defects in chronic osteomyelitis.
- This innovative approach simplifies the surgical procedure, shortens the treatment cycle, and results in a low incidence of complications.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
