    Abstract Achilles tendinopathy is a prevalent issue among athletes, often resistant to traditional treatments, and can persist chronically. This report presents a 23-year-old female track athlete suffering from refractory Achilles tendinopathy for four years. Despite initial treatments including rehabilitation, the use of insoles, steroid injections, and extracorporeal shock wave therapy, her symptoms persisted. Implementing a combination of innovative treatments - transarterial embolization, extracorporeal shock wave therapy, and prolotherapy - resulted in a significant improvement in symptoms. The case underscores the potential efficacy of a multifaceted approach, suggesting that a combination of treatments may be essential for addressing the complex pathology of chronic Achilles tendinopathy.

    Abstract A 15-year-old female short-distance track and field athlete started to experience pain in her left great toe while competing. One month after the onset of symptoms, she was diagnosed with a stress fracture of the proximal phalanx of the great toe. Despite three months of conservative treatment, no bone healing was observed, resulting in a nonunion. To promote healing of the fractured area, a treatment method involving the combination of extracorporeal shock wave therapy (ESWT) with platelet-rich plasma (PRP) injection was pursued. Complete bone healing was achieved six weeks after the start of the treatment, enabling the patient to fully return to her sport. Based on our findings, the combined use of ESWT and PRP injections, both beneficial for bone healing, is a potentially effective treatment for nonunion of the stress fracture of the proximal phalanx of the great toe.

    Abstract A 16-year-old male had a right elbow contracture after dislocation. The patient underwent supine-position ultrasound-assisted arthroscopic surgery, combining open removal of the posterior oblique ligament with the medial collateral ligament. The elbow joint flexion angle improved from 120 degrees to 145 degrees, and the extension angle improved from -50 degrees to 0 degrees. The patient returned to sports without recurrence of elbow joint contracture three months after surgery. Supine-positioned ultrasound-assisted arthroscopic surgery for elbow joint contracture is a safe and effective technique that eliminates the need for intraoperative position changes and big skin incisions.

    Abstract We present a case study of a 61-year-old man who experienced sural neuropathy following calcaneus fracture surgery, which was effectively treated using ultrasound-guided hydrodissection. Postoperatively, while the patient exhibited good bony fusion, he reported pain on the lateral side of the calcaneus. Ultrasound findings did not suggest any nerve discontinuity, but localized tenderness around the sural nerve was observed. After hydrodissection using 0.09% lidocaine, the patient's pain significantly decreased. Although hydrodissection alleviated the pain, complete resolution was achieved only post plate removal and neurolysis. This study represents the first report on the efficacy of hydrodissection for postoperative sural neuropathy, suggesting its potential as an effective treatment option.

    Abstract Objective: We aimed to investigate the effect and safety of extracorporeal shock wave therapy (ESWT) on ischial apophysitis (IA) in young high-level gymnasts. We hypothesized that ESWT would be safe and effective in alleviating pain.
    Design: Retrospective case series.
    Setting: Funabashi Orthopedic Hospital.
    Patients: The subjects were 18 high-level gymnasts (mean age of 13 years) with a chief complain of chronic buttock pain diagnosed with IA.
    Interventions: Ten patients received only physiotherapy (PT), whereas 8 received both PT and ESWT to the ischial tuberosity. The basic protocol for ESWT was to use an energy dose of 0.20 mJ/mm 2 or less with 3000 shots per session at 4-week intervals.
    Main outcome measures: We investigated whether PT and ESWT relieved the pain and allowed the patient to return fully to gymnastics. Based on radiographs at the last observation, we examined whether early closure of the apophyseal line of the ischium and around hip joint on the affected side occurred.
    Results: In the PT group, pain was relieved in 2 of 10 patients. In the ESWT group, pain was relieved and full return to gymnastics was possible in all 8 patients. None of the patients showed early closure of the apophyseal line.
    Conclusions: Extracorporeal shock wave therapy can be a safe and effective treatment option for IA in young high-level gymnasts.

    Abstract Background: The deltoid ligament is a complex structure composed of multiple ligaments located on the medial side of the ankle joint that can be injured by ankle sprains. Although there have been previous reports on ultrasound imaging of the injured deltoid ligament, a systematic method for depicting each ligament component has not been established. This study aimed to clarify the ultrasound findings of the deltoid ligament in ankle sprains using a systematic scanning protocol.
    Methods: We examined the tenderness of the medial ankle and evaluated the ultrasound findings of the deltoid ligament in 169 sprained ankles with no fracture, within 3 days after injury. Observation and evaluation of the six components of the deltoid ligament were performed using a systematic scanning protocol with four probe positions.
    Results: Of the 169 ankles, 48 ankles had tenderness in the deltoid ligament. Ultrasonography confirmed deltoid ligament damage in 13 of these 48 ankles. Of the 13 ankles, 3 ankles had damages only in the superficial layer, 3 ankles only in the deep layer, and 7 ankles in both the superficial and deep layers.
    Conclusions: We clarified the details of the damage pattern of the deltoid ligament in acute ankle sprains. It was possible to identify the superficial and deep layers of the ligament and to observe the damage pattern of each ligament component in detail, and it appeared that ultrasonography could be used as a tool to evaluate the damage pattern of the deltoid ligament in acute ankle sprains.

    Abstract We present a case report demonstrating a new technique for intradiscal injection under ultrasound guidance in treating lumbar disc herniation. A 16-year-old female gymnast underwent this procedure and experienced relief from pain. Traditional methods have been noted for their technical challenges and potential risk of nerve root damage. In this case, our approach visualized the lateral side of the disc and improved needle visibility. This technique potentially offers a clearer high-resolution confirmation of the needle's position within the disc. It is considered that this technique is effective not only for performing precise injections but also for enhancing safety due to the clear depiction of the needle tip entering the intervertebral disc.

    Abstract Introduction: Stress fracture of the patella is an overuse disorder that occurs in the lower extremity. Surgery may be considered if conservative treatment does not work or if a quicker and more reliable return to sports is expected. Surgery is usually performed under fluoroscopic guidance based on the premise that the proper placement of the internal fixation material can be determined on radiographic images.
    Patient concerns: A 16-year-old female basketball player gradually became aware of pain in the anterior aspect of her right knee during basketball, without any particular history of trauma. A computed tomography scan revealed a small bone fragment on the lateral side of the distal end of the patella.
    Diagnosis: Stress fracture of the patella.
    Interventions: Since it was difficult to determine the exact location of the bone fragment on radiographs, the surgery was performed under ultrasound guidance rather than fluoroscopy. While checking the bone fragment with ultrasound images, insertion of the guide pin, drilling, and screw fixation were performed under ultrasound guidance.
    Outcomes: Postoperative computed tomography showed accurate screw insertion into the bone fragment. Two months after surgery, bony fusion was confirmed, and the patient returned to her preinjury level of basketball.
    Conclusion: Ultrasound-guided screw fixation was useful in this case in which internal fixation of fractures is difficult under fluoroscopic guidance.

    Abstract Objectives: An optimal load and ankle position for stress ultrasound of the injured anterior talofibular ligament (ATFL) are unknown. The objectives of this study were to compare stress ultrasound and ankle kinematics from a 6 degree-of-freedom (6-DOF) robotic testing system as a reference standard for the evaluation of injured ATFL and suggest cut-off values for ultrasound diagnosis.
    Methods: Ten fresh-frozen human cadaveric ankles were used. Loads and ankle positions examined by the 6-DOF robotic testing system were: 40 N anterior load, 1.7 Nm inversion, and 1.7 Nm internal rotation torques at 30° plantarflexion, 15° plantarflexion, and 0° plantarflexion. Bony translations were measured by ultrasound and a robotic testing system under the above conditions. After measuring the intact ankle, ATFL was transected at its fibular attachment under arthroscopy. Correlations between ultrasound and robotic testing systems were calculated with Pearson correlation coefficients. Paired t-tests were performed for comparison of ultrasound measurements of translation between intact and transected ATFL and unloaded and loaded conditions in transected ATFL.
    Results: Good agreement between ultrasound measurement and that of the robotic testing system was found only in internal rotation at 30° plantarflexion (ICC ​= ​0.77; 95% confidence interval 0.27-0.94). At 30° plantarflexion, significant differences in ultrasound measurements of translation between intact and transected ATFL (p ​< ​0.01) were found in response to 1.7 Nm internal rotation torque and nonstress and stress with internal rotation (p ​< ​0.01) with mean differences of 2.4 ​mm and 1.9 ​mm, respectively.
    Conclusion: Based on the data of this study, moderate internal rotation and plantarflexion are optimal to evaluate the effects of ATFL injury when clinicians utilize stress ultrasound in patients.
