The former included the Rüedi-Allgöwer, Kellam-Waddell, Ovadia, AO/OTA, and Letts classifications, which were convenient for assessing general fracture morphology, evaluating alignment, and deducing injury mechanisms. However, they were limited in visualizing articular surface, planning surgical approaches and fixation strategies. The latter included Topliss, four-column, three-column, and Leonetti classifications, which offer advantages in evaluating articular surface fractures, and in guiding surgical approaches and internal fixation strategies, but lack description of the spatial configuration of fracture surfaces. At present, no existing classification system incorporated all the elements required of an ideal system, and none achieve both satisfactory reliability and validity simultaneously.

Its imaging diagnosis, treatment methods, rehabilitation strategies, and prognosis assessment have always been the focus of academic attention. MRI examination is widely used in diagnosing Achilles tendon rupture, but it has disadvantages such as high cost, long examination time, and metal contraindications. Ultrasound examination has the advantages of being non-invasive, low cost, comfortable, and portable, and it also has high specificity and accuracy, which has significant application value. The treatment methods for Achilles tendon rupture mainly include conservative treatment and surgical treatment. The choice of treatment strategy should be comprehensively considered based on the patient's age, degree of injury, physical condition, and rehabilitation compliance. The advantage of conservative treatment is that it costs less and avoids incision infection or poor healing, but it has a higher re-rupture rate. The advantages of open surgery include direct visualization of the tendon end and application of correct tension to restore the tendon length, but it is prone to incision infection and sural nerve injury. Minimally invasive surgery has the advantages of small incision and low complications, and is increasingly being applied in clinical practice. Regardless of the treatment plan adopted, systematic rehabilitation plays a crucial role in improving functional prognosis. In my opinion, the current research focus is on the improvement of minimally invasive surgical methods, the development and clinical application of new anti-adhesion technologies, and the optimization design of personalized rehabilitation plans.

At 30 days after intervention, ultrasound was used to measure the thickness of palmar ligament and median nerve;electromyography was employed to measure the conduction velocity, latency and action potential of median nerve to assess function of the median nerve;the transverse ligament of wrist and the median nerve were subjected to hematorglineosin(HE) staining to observe tissue morphology. The concentrations of transforming growth factor β1(TGF β1), connective tissue growth factor(CTGF), and collagen typeⅠ(ColⅠ) and collagen type Ⅲ(Col Ⅲ) were detected by enzyme-linked immunosorbent assay (ELISA) to observe the concentrations of fibrosis-related factors. Immunofluorescence was used to detect the relative fluorescence intensity of TGFβ1 in the tissues of the median nerve and the transverse ligament of wrist.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Compared with model group, the thickness of the median nerve and palmar ligament in ultrasound group, non-ultrasound group and hormone group decreased, and the differences were statistically significant(&lt;i&gt;P&lt;/i&gt;&lt;0.05). In terms of electrophysiological examination, ultrasound group, non-ultrasound group and hormone group all showed improvements in the conduction velocity, latency and action potential of the median nerve, and the differences were statistically significant compared with model group(&lt;i&gt;P&lt;/i&gt;&lt;0.05). In terms of Elisa test, the concentrations of TGFβ1 in ultrasound group, non-ultrasound group and hormone group were lower than those in model group(&lt;i&gt;P&lt;/i&gt;&lt;0.05). The CTGF level in ultrasound group was decreased, and the difference was statistically significant(&lt;i&gt;P&lt;/i&gt;&lt;","PeriodicalId":23964,"journal":{"name":"Zhongguo gu shang = China journal of orthopaedics and traumatology","volume":"39 9","pages":"918-27"},"PeriodicalIF":0.0,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149070129","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}
