The purpose of our study is to prove that the autologous scapular spine bone graft is an alternative for the treatment of anterior shoulder instability and the clinical and radiological results are promising. Method: From July 2016 to August 2018, patients who were diagnosed as having anterior shoulder instability with subcritical (10%-15%) glenoid bone loss were treated by arthroscopic repair with autologous scapular spine bone graft. The inclusion criteria were (1) anterior shoulder instability underwent arthroscopic autologous scapular spine bone graft; (2) glenoid bone loss was within 10% to 15% (measured by Sugaya's method); (3) three complete sets of computed tomography (CT) scans (preoperative, 1 week after surgery, and 1 year after surgery) available; and (4) clinical follow-up time was at least 2 years. The exclusion criteria were (1) concomitant rotator cuff tear; (2) concomitant remplissage or SLAP repair;(3) previous surgery of the affected shoulder; (4) open surgery; and (5) incomplete radiological or clinical follow-up. The preoperative and postoperative Constant-Murley score, dietary approaches to stop hypertension (DASH) score, visual analog scale (VAS) score, and range of motion (ROM) were recorded. CT scans with 3-dimensional reconstruction were obtained at the first week after operation and at 1 year after operation; the graft resorption rate was consequently calculated. Results: Twenty-seven patients were qualified and enrolled in the study. No severe complication was recorded during follow-up. No redislocation or subluxation was found, and the apprehension tests were all negative. At the last follow-up, the mean Constant-Murley score was 89.74 AE 3.71, the mean DASH score was 9.77 AE 5.31, the mean VAS score was 0.74 AE 0.64, which are all improved significantly compared with preoperative scores (P ¼ .00,.00,.00, respectively). At the last follow-up, the ROM including anterior flexion, external rotation by side, and the internal rotation were well restored without significant difference compared with the contralateral shoulder (P ¼.48, .08, .47, respectively). At 1 year after operation, the resorption rate of the bone graft was 19.4%. Conclusion:This study found that anterior shoulder instability with subcritical (10%-15%) glenoid bone loss treated with arthroscopic autologous scapular spine bone graft with suture anchor fixation is safe and could achieve satisfactory result at short-term follow-up. Level of Evidence: Therapeutic case series.

Objective To analyze if general factors such as age, gender, dominant side, fasting blood sugar level, BMI (body mass index), smoking, and drinking play a role in graft resorption after arthroscopic autologous scapular spine bone grafting. Methods From July 2016 to August 2018, patients who were diagnosed with anterior shoulder instability with subcritical bone loss (10%–15%) and underwent arthroscopic autologous scapular spine bone graft transplant were retrospectively reviewed and enrolled in this study. The age, gender, dominant side, fasting blood sugar level, BMI, smoking, and drinking conditions of the enrolled patients were recorded. The graft resorption rate at postoperative 1 year was also measured on three‐dimensional computed tomography (3D‐CT) scans. The Pearson test and the Spearman test were used to identify any significant correlation between the general factors and graft resorption rate. Results A total of 27 patients who underwent arthroscopic autologous scapular spine bone graft for recurrent shoulder instability qualified and were included in this study. There were 20 males and seven females, the mean age was 30.8 ± 9.4 years, the mean follow‐up time was 29.3 months (range, 25–39 months), during which no severe complications such as infection, neurovascular injury, or re‐dislocation were observed. The bone graft healed in all cases, the mean healing time was 2.6 ± 0.5 months (range, 2–3 months). At the last follow‐up, the mean Constant–Murley score was 89.74 ± 3.71, the mean Disabilities of Arm, Shoulder and Hand (DASH) score was 9.77 ± 5.31, and the mean visual analogue score (VAS) was 0.74 ± 0.64. The apprehension test was all negative at final follow‐up. The fasting blood sugar level was 4.78 ± 0.42 mmol/L, BMI was 23.70 ± 4.70. Five patients were “smoking” and 22 “non‐smoking”, four patients were “drinking” and 23 were “non‐drinking.” The graft resorption rate at postoperative 1 year was 19.4% ± 7.5%. The Pearson test and the Spearman test showed no significant correlation between age, gender, dominant side, fasting blood sugar level, BMI, smoking, drinking, and graft resorption rate. Conclusion Age, gender, dominant side, fasting blood sugar level, BMI, smoking, and drinking were not significantly correlated with graft resorption after the arthroscopic autologous scapular spine bone graft for recurrent shoulder instability.

Aim. To assess the reporting quality of randomized controlled trials (RCTs) on acupuncture for primary insomnia (PI). Methods. Seven Chinese and English databases were searched for publication reporting RCTs on acupuncture for PI from the inception of the databases to August 6, 2021. The internationally recognized Consolidated Standards of Reporting Trials (CONSORT) statement and the International Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA) guidelines were used to evaluate the reporting quality. The agreement between two researchers was calculated by Cohen’s kappa. Results. A total of 102 eligible RCTs were assessed. According to the CONSORT statement (2017), the positive reporting rates of items such as “abstract,” “background,” “participants,” and “numbers analyzed” were above 80%. However, the positive reporting rates of items such as “sample size,” “randomization implementation,” “Outcomes and estimation,” “Ancillary analyses,” and “Registration” were below 20%. According to STRICTA guidelines, the positive reporting rates of items such as “style of acupuncture,” “reasons for acupuncture treatment,” “Number of needles inserted,” “Needle retention time,” “Treatment regimen,” and “precise description of the control intervention” were above 80%. However, the positive reporting rates of items such as “setting and context of treatment” and “practitioner background” were below 20%. Conclusion. It is essential to advocate the endorsement of the CONSORT statement and STRICTA guidelines to improve the quality of acupuncture RCT reports.

Based on the morphological characteristics of glenoid and greater tuberosity (GT) fractures and the relationship between them, we explored the injury mechanism of acute anterior shoulder dislocation associated with glenoid and GT fractures. Methods: From December 2013 to December 2019, we retrospectively reviewed the clinical data of patients who were diagnosed with acute anterior shoulder dislocation associated with glenoid and GT fractures in our hospital. According to the fracture site, a glenoid fracture group and a greater tuberosity fracture (GT) group were established, and the morphological characteristics of both glenoid and GT fractures were measured and statistically analyzed. Results: A total of 41 patients (43 shoulders) met the inclusion criteria (39 unilateral shoulders and 2 bilateral shoulders). The mean age was 50.21 years (range, 22-71 years). A total of 27 shoulder injuries (62.8%) were split GT fractures and 33 shoulder injuries (76.7%) were combined with rotator cuff tears. The mean size of glenoid fragments was 30.16% and the mean displacement was 8.85 mm. The mean size of GT fragments was 28.43 mm. The mean superoinferior and anteroposterior displacements of the GT fragment were 6.77 mm and 4.96 mm, respectively. There was a negative correlation between the size of glenoid and GT fracture fragments (r = −0.64, P < 0.05). The glenoid fragments in the Ideberg type Ia glenoid fracture group were smaller than those in the Ideberg type II glenoid fracture group (28.41% and 40.95%, respectively), while the size of GT fragments in the type Ia group were larger than those in the type II group (29.77 mm and 20.21 mm, respectively) (P < 0.05). The GT fragments in the split GT fracture group were larger than those in the avulsion or depression GT fracture group (33.69 mm, 19.07 mm and 21.12 mm, respectively), while the size of glenoid fragments in the split GT fracture group were smaller than those in the avulsion or depression GT fracture group (23.57%, 41.37%, and 43.42%, respectively) (P < 0.05). As for the displacement direction of GT fragments, depression fractures were mainly inferior displacements, avulsion fractures were mainly anterosuperior displacements, while split fractures were mainly posteroinferior displacements (P < 0.05). Multiple regression analysis suggested that the type and the fragment size of GT fractures have a significant influence on the size of glenoid fragments. Conclusion: Acute anterior shoulder dislocations associated with glenoid and GT fractures are often combined with rotator cuff tears. There is a negative correlation between the size of glenoid and GT fragments, and split GT fractures are most common. Such injuries are highly correlated to the relative spatial location between the GT and the glenoid when the shoulder dislocates.

Objective: To report the clinical and radiological outcomes of arthroscopically assisted surgery for combination of glenoid and greater tuberosity fractures after traumatic shoulder dislocation. Methods: From December 2013 to December 2018, patients with concomitant fracture of the greater tuberosity and glenoid who underwent arthroscopically assisted surgery were retrospectively reviewed. Fifteen patients were included. Preoperative computed tomography (CT) scans with 3D reconstruction were performed to evaluate the fracture configuration and associated fractures. All patients underwent arthroscopically assisted surgery under general anesthesia with brachial plexus anesthesia in the lateral position. Under the arthroscopic approach, a comprehensive inspection of the joints was firstly conducted to examine the injury of bones and other tissues. With arthroscopy support, closed reduction and internal fixation of both fractures were performed with suture anchors, with or without additional cannulated screws. At the same time, other injuries were also repaired under the arthroscope. Patients were followed up (6 weeks，8 weeks，3 months，6 months，1 year after surgery) regularly for at least 1 year. At the follow-up, clinical outcomes (Constant score, ASES score, range of motion, and VAS score) and radiological outcomes were analyzed. Results: Of the 15 patients, there are seven cases of men, eight cases of women; aged 22-66 years, with an average age of 48 years; left shoulder for five cases, 10 cases of the right shoulder. The injury mechanisms were: a simple fall (n = 9), an epileptic seizure (n = 1), a high fall injury (n = 2), and a traffic accident (n = 3). Of the 15 cases of glenoid fracture, 11 cases were type Ia and four cases were type II according to the Ideberg Classification System. The mean size of the glenoid fracture fragment was 28.4% (range, 8.7%-47.2%). According to the Mutch classification system, the fractures of the greater tuberosity were divided into: five cases of avulsion, one case of compression, and nine cases of split. Average time of follow-up was 38.2 months (range, 12-70 months), and one case was lost to follow-up. With fractures healing well, almost all patients had a good joint function. At the final follow-up, mean anterior flexion was 157 ; mean external rotation was 40 ; mean internal rotation was T 11 level; the mean Constant-Murley score was 94.6 points (range, 70-100 points); the mean ASES score was 94.6 points (range, 79-100 points); and the mean VAS score was 0.4 points (range, 0-2 points). No recurrent instability or re-dislocation occurred. No patient had revision surgery. Conclusion: Arthroscopic management of glenoid and greater tuberosity bipolar fractures was useful and effective with minimal injury, and it achieved satisfactory clinical and radiological outcomes at a mean follow-up time of more than 3 years.
