Ilizarov technique for treating elbow stiffness caused by myositis ossificans: A case report.

Background: Myositis ossificans (MO) is a rare disease involving the formation of bone outside the musculoskeletal system. While surgical intervention is the main treatment approach, preventing recurrence and standardized rehabilitation are also crucial. Here, we present a surgical strategy to prevent the recurrence of MO.

[Expression of Ras-Associated Protein 1 in the Vascular Endothelium of Bone Tissue with Non-Traumatic Osteonecrosis of Femoral Head].

Objective: To investigate the difference in the expression of Ras-associated protein 1 (Rap1) in necrotic and healthy areas of non-traumatic osteonecrosis of femoral head (NONFH) patients.

Methods: Femoral head tissue samples from 30 cases of NONFH and 30 cases of traumatic osteonecrosis of the femoral head (TONFH) were collected after hip replacement surgery, respectively. No significant difference of Association Research Circulation Osseous (ARCO) staging was found between the NONFH and the TONFH groups ( =-0.

[Long non-coding RNA for metabolism of bone tissue].

The mechanism of metabolism of bone and cartilage are one of focus of orthopedic knowledge, and its clinical and basic study plays an important role in preventing and treating osteoporosis, degeneration of bone and joint, bone tumor. At present, the mechanism of metabolism of bone and cartilage studied from protein, signal pathway to mRNA transcription factor regulation. As a new regulatory factor for non-coding proteins, long non-coding RNA(LncRNA) participates in physiological and pathological process.

[Research progress of gene therapy in the treatment of non-traumatic osteonecrosis of femoral head].

There are many methods of conservative treatment for early non-traumatic osteonecrosis of femoral head, but still lack of a mature and effective treatment. Gene therapy is a new treatment method for non-traumatic osteonecrosis of femoral head in recent years. This article showed that the non-traumatic osteonecrosis of femoral head related to progress and problems on pathogenesy, molecular biology foundation, exogenous theoretical gene,carrier selection and so on, discussed some problems and countermeasure and future applications.

[Update of research on minimally invasive treatment of lumbar disc herniation].

There has been rapid progress in endoscopy-and imaging technology-based minimally invasive surgery for the treatment of lumbar disc herniation (LDH). It is advategeous over conventional surgery in that it not only reduces surgical trauma but relieves sufferings of patients. However, endoscopy-and imaging technology-based minimally invasive surgery cannot completely replace traditional surgery at present because of its limited indications.

[Investigations and analysis of traumatic condition of Longnan area in Wenchuan earthquake].

Objective: To investigate and analyze the traumatic conditions of Longnan area of Gansu in Wenchuan earthquake, and to explore the measures coping with unexpected disasters.

Methods: A sample survey including questionnaire survey, interviews and other methods was adopted to investigate the conditions of affected population of Longnan area in earthquake, especially on the traumatic conditions, the injured causes, treatment methods.

Results: In the sample survey of a total of 1652 earthquake casualties, the dead were 16 and the patients with extremities fractures were 750 (45.
