OBJECTIVE: To explore effectiveness of musculoskeletal ultrasound combined with Wide-Awake technique in extensor indicis proprius tendon (EIP) transfer for repairing extensor pollicis longus tendon (EPL) rupture. METHODS: A clinical data of 20 patients with EPL spontaneous rupture, who were admitted between January 2019 and June 2024 and met the selective criteria, was retrospectively analyzed. During EIP transfer surgery, the musculoskeletal ultrasound-guided incision marking combined with Wide-Awake technique was used in combination group (n=10) and the tourniquet-assisted surgery under brachial plexus block anesthesia in the control group. There was no significant difference in the baseline data between groups (P>0.05), including gender, age, affected side, cause and location of tendon rupture, and time from injury to hospitalization. The accuracy of preoperative musculoskeletal ultrasound in predicting the actual tendon rupture site was evaluated in the combination group. The operation time, intraoperative blood loss, visual analogue scale (VAS) scores during operation and at 6 hours after operation, total incision length, and postoperative complications were recorded. Surgical outcomes were assessed at 12 months after operation using the specific EIP-EPL evaluation method (SEEM), which included measurements of thumb elevation loss, thumb flexion loss, index finger dorsiflexion loss, and total score. RESULTS: In the combination group, the incision position marked by preoperative musculoskeletal ultrasound positioning was consistent with the actual tendon rupture position. Compared with the control group, the operation time and total incision length in the combination group were significantly shorter and the VAS score at 6 hours after operation was significantly higher (P<0.05). There was no significant difference in intraoperative blood loss or intraoperative VAS score between groups (P>0.05). All incisions in both groups healed by first intention. Two patients in the control group developed swelling and blisters in the tourniquet area, which subsided spontaneously without special treatment. All patients were followed up 12-14 months, with an average of 12.5 months. The thumb dorsiflexion function of all patients recovered to varying degrees. At last follow-up, the thumb elevation loss in combination group was significantly lower than that in control group, and the total score was significantly higher (P<0.05); there was no significant difference in thumb flexion loss or index finger dorsiflexion loss between groups (P>0.05). CONCLUSION Musculoskeletal ultrasound can accurately locate the site of tendon rupture, assist the Wide-Awake technique in implementing precise anesthesia, and adjust tendon tension while reducing tissue trauma, with satisfactory effectiveness.

OBJECTIVE: To retrospectively analyze the healing degree of graft in patients who underwent over-the-top reconstruction of the anterior cruciate ligament(ACL) using autologous tendon 1 year postoperatively to find out possible risk factors. METHODS: From January 2017 to March 2023, 207 patients with more than 1 year of follow-up and 1-year postoperative MRI were selected from that receiving ACL autograft tendon over-the-top reconstruction surgery including 137 males and 70 females, with a mean age of (28.01±9.71) years rangeding 12 to 56 years old;time from trauma to surgery was (5.80±3.78) months. All patients had intra-operative pivoshift tested asⅠtoⅡdegree. The 1-year postoperative magnetic resonance imaging (MRI) results were categorized by Howell's method, classifying degreesⅠandⅡas group BHD (better healing degree), while degrees Ⅲ and Ⅳ as group PHD (poorer healing degree). Potential influencing factors such as age, gender, whether it was a sports injury, time from injury to surgery, time to return to sports after surgery, body mass index (BMI), Beighton score, knee hyper-extension, diameter of the graft, whether it was remnant-preserving or not, whether the medial and lateral meniscus were resected, sutured or not, posterior lateral tibial slope, intercondylar notch width ratio (ICNWR), and lateral femoral condyle depth ratio (LFCDR) were analyzed by univariate analysis and Logistic regression to find the influencing factors. RESULTS: All patients were follow-up time for (18.59±4.63) months, and all the patients had good wound healing without any infection after surgery. There were 3 cases of re-ruptrure and 2 cases with secondary medial meniscus barrel handle-like tear 1 year after surgery, which received arthroscopic surgical treatment. Univariate analysis showed statistically significant difference in time from injury to surgery, time from surgery to return to sports, ICNWR, posterior lateral tibial slope, and BMI between the two groups(P<0.05). Multi-factorial regression analysis showed that smaller ICNWR, OR=0.684, 95%CI(0.528, 0.886), P=0.004; larger posterior lateral tibial slope, OR=1.557, 95%CI(1.222, 1.984), P<0.001;larger BMI, OR=1.724, 95%CI(1.369, 2.172), P<0.001;and shorter return-to-sport time<6 months vs. 6 to 12 months, OR=0.167, 95%CI(0.041, 0.672), P=0.012;<6 months vs.>12 months, OR=0.022, 95%CI(0.004, 0.108), P<0.001 might be risk factors for poor MRI healing degree 1 year postoperatively. CONCLUSION In patients received ACL autograft tendon over-the-top reconstruction, smaller ICNWR, larger posterior lateral tibial slope, larger BMI, and shorter time to return to sports may all be high-risk factors for poor graft healing degree on MRI 1 year postoperatively, and the surgical technique and the postoperative rehabilitation are supposed to be individualized for such patients.

The fenrou zhijian is defined as potential gap between different layers in the three-dimensional network structure formed by the twelve meridian tendons. Various pathological changes of the meridian tendons lead to the adhesion and closure of fenrou zhijian, causing abnormal mechanical conduction of the meridian tendon system, which in turn leads to painful bi syndrome of meridian tendons. As such, restarting the fenrou zhijian is the key to acupuncture treatment for painful bi syndrome of meridian tendons. Under the guidance of musculoskeletal ultrasound, the level and the angle of needle insertion of acupuncture at fenrou zhijian could be accurately controlled, the efficacy of acupuncture is improved.

The bony naso-orbital-ethmoid (NOE) complex is a 3-dimensional delicate anatomic structure. Damages to this region may result in severe facial dysfunction and malformation. The management and optimal surgical treatment strategies of NOE fractures remain controversial. For a patient with NOE trauma, doctors should perform comprehensive clinical examination and radiographic analysis to assess the type and extent of fracture. The results of assessment will assist doctors to make a patientspecific program for the sake of reducing post-operation complications and restoring normal appearance and function as much as possible. This review focuses on the advancement of management of NOE fractures including symptoms, classifications, diagnosis, approaches, treatment and new techniques in this field.

Ultrasonography (US) is a cost effective diagnostic imaging tool suitable for routine clinical use. High frequency US is a well-established method for both the diagnosis and monitoring of inflammatory arthritis, capable of detecting a wide range of joint pathologies, including effusion, synovitis, and extra-articular abnormalities. However, to ensure an accurate diagnosis, it is also important to consider periarticular disorders that could clinically mimic joint pathology. Such a diagnosis requires special attention to be paid to the periarticular structures, include the tendon, ligament, muscle, and bursa. Due to the close proximity of these structures to potentially affected joints, periarticular inflammation is often clinically misdiagnosed as articular in origin. In these cases, the processes driving pathology are the result of localized inflammation that is secondary to inflammatory arthritis, such as excessive friction or direct trauma. Therefore, when using US to diagnose inflammatory arthritis, it is important to understand the causative pathology of the periarticular disorders, as well as their clinical presentation.

BACKGROUNDConventional ultrasonography or magnetic resonance (MR) imaging is commonly performed to obtain information about the severity of the disease, location of the injury, and differential diagnosis. The aim of this research was to investigate the diagnostic confidence of sonoelastography as an adjunct to greyscale ultrasonography in lateral elbow tendinopathy.

METHODSA single experienced physiatrist performed greyscale ultrasonography and sonoelastography in 28 patients (9 men, 19 women; mean age, 48.5 years; age range, 36-67 years) with unilateral symptoms of lateral elbow tendinopathy; the asymptomatic elbows were used as controls. Greyscale images were described as normal, tendinosis, partial-thickness tear, and full-thickness tear. Sonoelastographic images of the common extensor tendon were analyzed qualitatively (scoring of the elastic spectrum) and quantitatively (based on a color histogram).

RESULTSBoth the imaging methods had high sensitivity, specificity, and accuracy for diagnosing lateral elbow tendinopathy. Considering the clinical diagnosis of lateral elbow tendinopathy, sonoelastography showed significantly higher diagnostic accuracy (96.4%) than ultrasonography (89.5%, P < 0.01). Quantitative analysis showed objective interpretation of the sonoelastographic images that revealed greater intensity of green and blue pixels in symptomatic elbows (P < 0.01).

CONCLUSIONSonoelastography increases diagnostic confidence in tennis elbow pathology over greyscale ultrasonography alone and may be an additional powerful diagnostic tool in cases of lateral elbow tendinopathy with inconclusive greyscale ultrasonographic findings.

BACKGROUNDIt has been demonstrated that bone tunnel widening could appear after knee anterior cruciate ligament (ACL) reconstruction, especially for those patients whose ruptured ACL were reconstructed with semitendinosus and gracilis tendons. Many factors can influence the extent of tunnel widening. Few studies have investigated the relationship between bone tunnel widening and rehabilitation procedures. This research was carried out to find the rehabilitation procedures' influence on the tibial bone tunnel widening after ACL reconstruction.

METHODSSixty-five cases, whose ACL reconstructions were done using quadrupled semitendinosus and gracilis tendons, were divided into two groups. Group A had 33 cases, 19 men, 14 women, averaged (31.2 +/- 12.4) years old, only ACL reconstruction was done using Paessler's technique, and aggressive rehabilitation procedure was used for function recovery post operation. Group B had 32 cases, 20 men, 12 women, averaged (30.3 +/- 10.3) years old. Except for ACL reconstruction, every patient in group B accepted meniscus repair using re-fixation methods or cartilage repair using microfracture technique, conservative rehabilitation procedure was used post operation. Six months post operation, standard posterior-anterior radiographic plates were taken for each case, CorelDRAW 8.0 software was used to digitize all X-ray plates and measure the upper, middle and lower parts of the tibial tunnel. Magnification effect of X-ray plates was taken out after measurement.

RESULTSSix months after ACL reconstruction the tibial tunnel widening of the upper, middle and lower parts on both the posterior-anterior and lateral X-ray plates in Group A with aggressive rehabilitation procedure was much more serious than in Group B with conservative rehabilitation. KT-1000 knee stability measurement and clinical manifestation showed no difference between the two groups.

CONCLUSIONSRehabilitation procedure after ACL reconstruction is one of the reasons for tunnel widening. It not only can directly influence the function recovery of ACL reconstructed knee, but also perhaps indirectly influence the function recovery and long-term clinical result of the operated knee by influencing the tunnel widening.
