Closed reduction and intramedullary nailing, due to their minimally invasive nature and ability to promote fracture healing, have become the mainstream treatment for FSF. However, accurately assessing and correcting rotational deformities during surgery remains a major challenge for this technique. This article reviews the research progress on the assessment and correction of rotational deformities in closed reduction and intramedullary nailing of FSF. Current assessment methods involve the wire-drawing method, femoral neck anteversion angle method, lesser trochanter-femoral shaft tangent method, cortical \"step-sign\" method, lesser trochanter morphology comparison method, greater trochanter inclination index quantification method, and computer-assisted navigation for reduction. These methods all have their own advantages and disadvantages, and the choice depends on fracture type, hospital resources, and surgical skill. Methods for correcting rotational deformities are mainly divided into two types:closed reduction under traction and percutaneous device-assisted reduction. Closed reduction under traction is easy to perform and suitable for patients with mild shortening deformities. However, it's less effective for patients with extensive shortening, and may cause iatrogenic fractures and nerve injuries. Percutaneous device-assisted reduction can effectively reduce surgical time, blood loss, and radiation exposure. However, it still has limitations when dealing with complex fractures. In recent years, the application of computer-assisted navigation for reduction has offered new possibilities for the precise correction of rotational deformities. However, it's operationally complex and demands high technical skills from surgeons. This article, through a review of existing methods, aims to provide clinicians with more references. It is expected to achieve more accurate rotational deformity correction in the treatment of FSF, thereby improving patients' prognosis.</p>","PeriodicalId":23964,"journal":{"name":"Zhongguo gu shang = China journal of orthopaedics and traumatology","volume":"39 8","pages":"842-8"},"PeriodicalIF":0.0,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148866972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a random number table method, patients were divided into two groups according to the postoperative lumbar corset wearing time:70 cases in the 1-month wearing group 70 cases, including 20 males and 50 females, aged (63.4±7.9) years;and 50 cases in the 3-month wearing group, including 18 males and 35 females, aged (64.3±7.5) years. To deeply analyze the impact of osteoporosis status on outcomes, all patients were further divided into an osteoporosis subgroup (54 cases) and a non-osteoporosis subgroup (69 cases) based on preoperative bone mineral density results following the initial randomization. All patients underwent plain lumbar CT scans preoperatively and at 1, 3, and 6 months postoperatively. Bone's FRAX V1.0 software was used to quantitatively measure vertebral bone mineral density and assess screw stability, aiming to compare the temporal changes under different wearing durations and different bone mineral density states.

This technology through precise biological tissue engineering, and can be produced with the patient's own tissue matching the artificial bone implants, thus in the bone graft surgery and cosmetic surgery play a key role. With the deepening of the research found that different material and printing method can significantly affect the artificial bone implant biological specificity and clinical effect. In addition, the personalization of 3D printing implants can better adapt to the patient's anatomical structure, improve the success rate of surgery and patient satisfaction. In recent years, 3D printing technology in expanding the application of orthopedic surgery, its potential value also gradually by mining.
