ObjectiveTo observe the accuracy of location and operation of traditional blind acupotomy lysis in the treatment of scapulohumeral periarthritis by using the high-frequency ultrasound.MethodsForty-two patients with scapulohumeral periarthritis diagnosed in the First Affiliated Hospital of Xinjiang Medical University and Urumqi Hospital of Traditional Chinese Medicine from February to April 2018 were selected. Four common sites of needle knife in the treatment of scapulohumeral periarthritis were operated blindly, and the process of the needle insertion points location and needle perform were both observed by high-frequency ultrasound.ResultsUsing high-frequency ultrasound to observe and confirm the bare-handed positioning point and needle-knife operating point, we found that the accuracy rate of bare-handed positioning needle-point was 100.0% (42/42). In the process of needling, the accuracies of needle insertion at the point of small tubercle of humerus and the point of bursa of deltoid muscle were high, which was 95.2% (40/42) and 100.0% (42/42), respectively. However, because of the deviation of the needle depth and direction, the accuracies of needle insertion at the coracoid point and the sulcus point between the humeral tubercles were low, which was 45.2% (19/42) and 4.8% (2/42), respectively.ConclusionsTraditional acupotomy lysis is a commonly used method of needle knife treatment. Using high-frequency ultrasound, it is found that even by experienced needle knife doctors, there may still be positioning deviation when using blind method to insert needles. Because the visualization of clinical needle knife is difficult to be carried out universally due to the limitations of time and technology, it is suggested that high-frequency ultrasound could be used as a visualization teaching tool in the training of needle knife operation to assist the training of blind needle knife operation technology, which may improve the accuracy of blind needle knife operation.
ObjectiveTo analyze the feasibility and effectiveness of elastic intramedullary nail fixation for the fifth metacarpal neck fracture under the guidance of high frequency ultrasound.MethodsThe clinical data of 30 patients with the fifth metacarpal neck fractures who were treated with elastic intramedullary nails fixation under the guidance of high frequency ultrasound and met the selection criteria between May 2013 and September 2017 were retrospectively analysed. There were 24 males and 6 females, the age ranged from 18 to 58 years, with an average of 31.4 years. The head-shaft angle of the fifth metacarpal was (55.6±11.3)°. The time from injury to operation was 12 hours to 8 days, with an average of 2.4 days. The operation time, number of intraoperative fluoroscopy, fracture reduction, complications, and fracture healing time were recorded. The head-shaft angle of the fifth metacarpal on the affected side after fracture healing were measured and compared with the healthy side. At last follow-up, the active range of motion of the fifth metacarpophalangeal joint of both sides were measured, and the function was evaluated by using the total active movement (TAM) evaluation standard of the Hand Surgery Association of Chinese Medical Association.ResultsThe operation time was 22-40 minutes, with an average of 32.4 minutes; the intraoperative fluoroscopy was performed once; ultrasound images and X-ray fluoroscopy showed that the fracture was well reduced and no adjustment was required. The incisions healed well after operation, without tendon adhesion or local numbness. All 30 patients were followed up 8-16 months, with an average of 11.7 months. The fracture healing time was 4-8 weeks, with an average of 5.6 weeks. The head-shaft angle of the fifth metacarpal was (13.2±1.4)°, which was significantly improved when compared with preoperative value (t=−20.02, P=0.00); and there was no significant difference (t=1.94, P=0.06) when compared with the healthy side [(12.6±1.0)°]. At last follow-up, the active range of motion of the fifth metacarpophalangeal joint on the affected side was (89.4±2.4)°, showing no significant difference (t=−1.58, P=0.13) when compared with the healthy side [(90.3±2.0)°]. According to the TAM evaluation standard of the Hand Surgery Association of Chinese Medical Association, all patients were considered to be excellent.ConclusionThe effectiveness of elastic intramedullary nail fixation for the fifth metacarpal neck fracture under the guidance of high frequency ultrasound is definite. It can dynamically observe the fracture reduction from different angles, reduce ionizing radiation and postoperative complications.
Objective To explore the effect of self-designed early rehabilitation procedure of frozen shoulder incorporating high-frequency ultrasound technology in the outpatient treatment of patients with early frozen shoulder. Methods One hundred and eighty-two consecutive patients who attended the outpatient clinic of the Department of Rehabilitation Medicine of the First Affiliated Hospital of Xinjiang Medical University and were diagnosed with frozen shoulder between January 2018 and May 2021 were selected and randomly divided into the trial group and the control group, with 91 patients in each group. Patients in the trial group received early rehabilitation procedures for frozen shoulder, and patients in the control group received conventional physiotherapy. The Visual Analogue Scale (VAS) (including VAS score for resting pain and VAS score for active motion), active range of motion of the shoulder joint (external rotation, forward flexion, and abduction), Shoulder Pain and Dysfunction Index (SPADI) (including pain subscale score, dysfunction subscale score, and total score) were compared between the two groups before treatment (Week 0) and 4 and 8 weeks after the start of treatment (Week 4 and 8). Results A total of 143 patients (74 in the trial group and 69 in the control group) completed the study. There was no significant difference in any assessment index between the two groups in Week 0 (P>0.05). The results of the within-group comparison after treatment showed that the VAS score for resting pain (F=44.359, P<0.001), VAS score for active motion (F=158.458, P<0.001), anterior shoulder flexion (F=123.334, P<0.001), abduction mobility (F=117.539, P<0.001), total SPADI score (F=133.814, P<0.001), SPADI pain subscale score (F=74.093, P<0.001), and SPADI dysfunction subscale score (F=145.336, P<0.001) in Week 4 and 8 were better than those in Week 0, and the assessments in Week 8 were better than those in Week 4 in each group (P<0.05); in the control group, there was no statistically significant difference in the external rotation mobility of the shoulder in Week 4 compared with that in Week 0 (P=0.599), and the external rotation in Week 8 improved significantly compared with that in Week 0 (P<0.001), whereas the external rotation of the shoulder in Week 4 and 8 in the trial group improved significantly compared with that in Week 0 (P<0.001). The results of the between-group comparison after treatment showed that the two groups had statistically significant differences in resting shoulder pain VAS score (F=93.712, P<0.001), active motion VAS score (F=103.565, P<0.001), external shoulder rotation (F=13.388, P<0.001), anterior shoulder flexion (F=66.375, P<0.001), abduction mobility (F=110.253, P<0.001), total SPADI score (F=7.917, P=0.006), and SPADI pain subscale score (F=39.091, P<0.001); the SPADI dysfunction subscale score was lower in the trial group than that in the control group in Week 4 (P=0.002), but by Week 8 there was no statistically significant difference between the two groups (P=0.352). Conclusion The early rehabilitation program for frozen shoulder incorporating high-frequency ultrasound technology is more effective than conventional physiotherapy in the intervention of patients with early frozen shoulder, and may provide a referenceable example for the combined application of high-frequency ultrasound technology and physiotherapy.
