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 compare effectiveness of injecting platelet-rich plasma (PRP) with different concentrations of leukocytes under ultrasound in treatment of supraspinatus tendon injury. METHODS: A clinical data of 30 patients with supraspinatus tendon injury, who met the selection criteria and were admitted between December 2022 and December 2023, was retrospectively analyzed. Thirty patients were treated with 4 injections of leukocyte-poor PRP (LP-PRP, n=10), leukocyte-rich PRP (LR-PRP, n=11), and triamcinolone ( n=9), with an interval of 7-10 days between each injection. There was no significant difference between groups ( P>0.05) in the age, gender, disease duration, affected shoulder side, Ellman classification, preoperative visual analogue scale (VAS) score, Constant score, Disabilities of the Arm, Shoulder, and Hand (DASH) score, and American Shoulder and Elbow Surgeons (ASES) score. At 1, 3, and 6 months after injection, the shoulder pain and function were evaluated by using the VAS score, Constant score, DASH score, and ASES score. MRI was conducted to observe supraspinatus tendon healing. RESULTS: No severe adverse reactions was observed in all groups. All patients were followed up 6-7 months, with an average of 6.5 months. After injection, the ASES score and Constant score gradually increased in the LR-PRP group and LP-PRP group, while the VAS score and DASH score decreased, with significant differences compared to before injection ( P<0.05). Except for no significant difference between 3 and 6 months after injection in LR-PRP group ( P>0.05), the above scores showed significant differences between different time points ( P<0.05). At 1 month after injection, the Constant score in triamcinolone group significantly increased compared to before injection, while the VAS score significantly decreased ( P<0.05). There was no significant difference in all scores between other time points in the triamcinolone group ( P>0.05). Except for 1 month after injection, there was no significant difference in Constant score and VAS score between groups ( P>0.05). At all other time points, the LR-PRP group and LP-PRP group had better scores than the triamcinolone group ( P<0.05). There was no significant difference between the LR-PRP group and the LP-PRP group ( P>0.05). MRI showed that only 4 patients in the LP-PRP group had signs of repair at the supraspinatus tendon injury site at 6 months after injection, while no significant tendon repair sign was observed in the other patients. CONCLUSION Compared with triamcinolone treatment, multiple injections of LP-PRP and LR-PRP under ultrasound can promote the recovery of shoulder joint function and significantly relieve pain in patients with supraspinatus tendon injury, and imaging improvement can be seen after LP-PRP treatment.

Flexor carpi radialis (FCR) muscle is located in the forearm anteriorly that runs through a synovial fibro-osseous tunnel in the forearm. We described a case of FCR tendon rupture due to repetitive overuse injury. A 55-year-old man, right-hand dominant, presented with right forearm pain and swelling which started 3 days ago while playing amateur golf. Focal tenderness and bruising over volo-ulnar region of the right forearm were examined. Plain radiographs showed soft tissue edema around lesion area and no detectable fracture. Ultrasonography showed multiple hypoechoic lesions suspected as hematoma of the flexor muscle group. After done magnetic resonance imaging, he was diagnosed with rupture of FCR tendon at proximal origin and strain of flexor digitorum superficialis and palmaris longus muscle. He received compressive dressing and restriction of wrist range of motion for three weeks. Two months later, remaining traces of lesions were observed at the follow-up ultrasonography and the pain disappeared.

OBJECTIVE: To compare the clinical outcomes following conservative treatment and arthroscopic repair in patients with a rotator cuff tear. METHODS: In this retrospective study, patients aged >50 years with a symptomatic rotator cuff tear were reviewed. The rotator cuff tendons were evaluated using ultrasonography, shoulder magnetic resonance imaging or MR arthrography, and the patients with either a high-grade partial-thickness or small-to-medium-sized (≤3 cm) full-thickness tear were included in this study. The primary outcome measures were a pain assessment score and range of motion (ROM) at 1-year follow-up. The secondary outcomes were the rate of tear progression or retear along with the rate of symptom aggravation after the treatments. RESULTS: A total of 357 patients were enrolled, including 183 patients that received conservative treatment and 174 patients who received an arthroscopic repair. The pain assessment score (p<0.001) and the ROM in forward flexion (p<0.001) were significantly improved in both groups. The ROM in internal rotation did not significantly change after conservative treatment and arthroscopic repair. The pain assessment score and ROM were not significantly different between the two groups. Retear was observed in 9.6% of patients who had an arthroscopic repair and tear progression was found in 6.7% of those who underwent conservative treatment. The proportion of aggravation for pain and ROM did not significantly differ between the two groups. CONCLUSION: The effectiveness of conservative treatment is not inferior to arthroscopic repair for patients >50 years old with a less than medium-sized rotator cuff tear in a 1-year follow-up period. Further study is warranted to find the optimal combination of conservative treatment for a symptomatic rotator cuff tear.

Avulsion injury of the flexor digitorum profundus (FDP) tendon from the distal phalanx is considered as a rare injury. We report a patient who sustained a FDP tendon rupture insertion on her fifth finger as a result of a closed, hyperextension with no accompanying laceration or predisposing pathologic condition. Preoperative ultrasonography showed complete rupture of FDP and the gap between the tendon ends. According to the classification by Leddy and Pacter, this case is type II. The reconstruction of flexor tendon using pull-out suture and tie-over button. We are reporting a case with brief review of literatures.

BACKGROUND: This study was designed to perform conventional ultrasonography, magnetic resonance arthrography (MRA) and arthrosonography exams after rotator cuff repair to compare the results of conventional ultrasonography and arthrosonography with those of MRA as the gold standard. METHODS: We prospectively studied 42 consecutive patients (14 males, 28 females; average age, 59.4 years) who received arthroscopic rotator cuff repair due to full-thickness tears of the supraspinatus tendon from 2008 to 2010. The integrity assessment of the repaired rotator cuff was performed 6 months postoperatively using conventional ultrasonography, MRA, and arthrosonography. RESULTS: The diagnostic accuracy of the conventional ultrasonography compared to MRA was 78.6% and the McNemar test results were 0.016 in full-thickness tear and 0.077 in partial-thickness tear. The diagnostic accuracy of arthrosonography compared to MRA was 92.9% and the McNemar test results were 0.998 in full-thickness tear and 0.875 in partial-thickness tear. CONCLUSIONS: It was found that the integrity assessment of the repaired rotator cuff by ultrasonography must be guarded against and that arthrosonography is an effective alternative method in the postoperative integrity assessment. Also, an arthrosonography seems to be a suitable modality to replace the conventional ultrasonography.

A twenty-year-old male visited our clinic with wrist and long finger metacarpophalangeal (MP) joint pain. Dynamic ultrasonography revealed sagittal band (SB) ulnar subluxation and extensor carpi ulnaris (ECU) volar subluxation. Magnetic resonance imaging showed longitudinal splitting and dislocation of the volar half slip of the ECU tendon. The redundant radial SB was augmented and ECU sheath was advanced to the periosteum using suture anchors. He was able to perform his previous activities at the last follow-up. We encountered a case of "simulateous" ECU dislocation with extensor tendon subluxation of the long finger at the MP joint. Therefore, we report this case with a review of the relevant literature.

OBJECTIVE: The purpose of this study was to demonstrate the ultrasonographic (US) findings of rupture and the healing process of the medial head of the gastrocnemius ("Tennis Leg"). MATERIALS AND METHODS: Twenty-two patients (age range: 30 to 45 years) with clinically suspected ruptures of the medial head of the gastrocnemius were referred to us for US examination. All the patients underwent US of the affected limb and the contralateral asymptomatic limb. Follow-up clinical evaluation and US imaging of all patients were performed at two-week intervals during the month after injury and at one-month intervals during the following six months. RESULTS: Of the 22 patients who had an initial US examination after their injury, partial rupture of the medial head of the gastrocnemius muscle was identified in seven patients (31.8%); the remaining 15 patients were diagnosed with complete rupture. Fluid collection between the medial head of the gastrocnemius and the soleus muscle was identified in 20 patients (90.9%). The thickness of the fluid collection, including the hematoma in the patients with complete rupture (mean: 9.7 mm), was significantly greater than that seen in the patients with partial tear (mean: 6.8 mm) (p < 0.01). The primary union of the medial head of the gastrocnemius with the soleus muscle in all the patients with muscle rupture and fluid collection was recognized via the hypoechoic tissue after four weeks. CONCLUSION: Ultrasonography is a useful imaging modality for the diagnosis and follow-up examination for the patients suffering with rupture of the medial head of the gastrocnemius.
