Objective To explore the differences in scapular motion and shoulder function between patients suffering from rotator cuff tears(RCT)with and without type Ⅲ scapular dyskinesis(SD).Meth-ods Between September 2021 and March 2023,sixteen patients suffering from rotator cuff tears with SD(SD group)and 17 counterparts without SD(non-SD group)were recruited from the Sports Hospital of the General Administration of Sport of China.Their scapular motion was assessed by measuring three parameters in the X-rays,including scapular spine line(LSS),scapular upward rotation angle(SU-RA),and coracoid upward shift distance(CUSD).Moreover,their shoulder range of motion in flexion,abduction and external rotation were recorded,and further evaluated using the Pain Visual Analog Scale(VAS)and American Shoulder and Elbow Surgeons Score(ASES).Results No significant differenc-es were found between the two groups in the average score of SURA,CUSD and LSS at 0°～30° shoul-der abduction,or in that of CUSD and LSS at 60°～90°shoulder abduction.However,the average SU-RA score of the SD group at 60°～90°shoulder abduction was significantly greater than the other group(P<0.05).The shoulder ranges of motion during active flexion,abduction and external rotation were significantly smaller in the SD group than in the non-SD group(P<0.05).Moreover,the average VAS score in the SD group was significantly higher than the non-SD group(P<0.05),while the average ASES score was significantly lower than the latter group(P<0.05).Conclusions RCT patients type III SD exhibits greater scapular upward rotation during shoulder abduction compared to those without SD.Moreover,the former patients suffer from more severe pain and have worse shoulder range of motion and functional performance than the latter.

Objective:To explore the clinical outcomes of intraoperative fluoroscopy on femoral tunnel placement in treating professional snow sports athletes with anterior cruciate ligament (ACL) injury.Methods:A retrospective case series study was used to analyze the clinical data of 13 professional snow sports athletes with ACL injury treated in the National Institute of Sports Medicine, General Administration of Sport of China from January 2016 to January 2019. There were 5 males and 8 females, aged 16-27 years [(18.5±3.0)years]. Intraoperative lateral fluoroscopy combined with quadrant method was performed for the accurate femoral tunnel placement in single-bundle ACL reconstruction by using autologous hamstring tendon in all patients. KT1000 side-to-side difference (KT1000-ssd), pivot shift test, International Knee Documentation Committee (IKDC) subjective score, Lysholm score, Marx activity scale and maximum extension and flexion resistance ratio of the involved and uninvolved knee were compared before operation (or before injury) and at 3, 6, 12 and 24 months after operation. Whether returning to the field, time taken in returning to the field and re-injury were recorded at each follow-up visit. ACL graft signal intensity ratio (SIR) in MRI of the involved knee was evaluated at postoperative 24 months.Results:All patients were followed up for 24-33 months [(25.8±2.7)months]. There were 7 patients with KT1000-ssd degree I, 5 with degree II and 1 with degree III before operation, compared to 12 patients with KT1000-ssd degree 0 and 1 with degree I at 3 and 6 months after operation and 13 patients with KT1000-ssd degree 0 at 12 and 24 months after operation. The pivot shift test was grade I in 8 patients and grade II in 5 before operation, compared to 11 patients with degree 0 and 2 with degree I at 3 months after operation and 12 patients with degree 0 and 1 with degree I at 6, 12 and 24 months after operation. IKDC subjective score was (68.0±4.3)points, (84.7±7.9)points, (94.6±3.3)points and (96.5±1.8)points at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, IKDC subjective score was significantly improved compared to the preoperative (48.3±25.0)points (all P<0.01). The Lysholm score was (63.4±6.6)points, (80.1±6.5)points, (93.8±4.6)points and (96.5±2.4)points at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, the Lysholm score was significantly improved compared to the preoperative (47.5±29.4)points (all P<0.01). The Marx activity scale was (7.4±0.5)points, (13.8±0.7)points, (14.6±0.8)points and (15.0±0.7)points at postoperative 3, 6, 12 and 24 months, respectively, significantly lower than (16.0±0.0)points before the injury (all P<0.01). The maximum extension resistance ratio of the involved and uninvolved knee was 0.60±0.10, 0.85±0.08, 0.91±0.06 and 0.97±0.04 at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, the maximum extension resistance ratio of the involved and uninvolved knee was significantly increased compared to the preoperative 0.57±0.18 (all P<0.01).The maximum flexion resistance ratios of involved and uninvolved knee were 0.64±0.09, 0.82±0.06, 0.89±0.04 and 0.94±0.06 at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, the maximum flexion resistance ratio of the involved and uninvolved knee was significantly increased compared to the preoperative 0.60±0.12 (all P<0.01). Thirteen athletes returned to the field within 12 months after operation with the time taken in returning to the field ranging from 5-12 months [(8.7±1.9)months]. There was no ACL re-injury at postoperative 24 months. The ACL graft SIR in MRI of the involved knee was 1.80±0.20 at postoperative 24 months. Conclusion:Intraoperative fluoroscopy on femoral tunnel placement in the treatment of professional snow sports athletes with ACL injury can significantly improve the knee joint stability, subjective function, sports performance and muscle strength within 6 months, and can help them return to the field within 12 months, and accelerates graft healing.

Objective:To summarize the clinical characteristics and efficacy of hemorrhage resulted from cortical venous infarction with seizure as the first symptom after craniotomy.Methods:Eleven patients with hemorrhage resulted from cortical venous infarction with seizure as the first symptom after craniotomy admitted to Neurosurgical Center, 988 th Hospital of PLA Joint Logistic Support Force from June 2011 to September 2019 were chosen in our study; primary diseases included meningioma in 7 patients, contusion and laceration of frontal lobe in 2, hypertensive cerebral hemorrhage in 1, and obsessive-compulsive disorder in 1 patient. Epilepsy was the first symptom after craniotomy. Clinical characteristics and efficacy of these patients were analyzed retrospectively; seizure control efficacy was evaluated by Engel grading. Results:First seizure occurred 4 h-7 d after craniotomy in these 11 patients, including 2 with focal sensory retention seizure, 3 with focal bilateral tonic-clonic seizure, and 6 with general tonic-clonic seizure. Follow-up cranial CT revealed hematoma in surgical region, adjacent cortex or subcortex in 9 patients (hematoma volume: 15-50 mL); emergency craniotomy (hematoma clearance) and decompressive craniectomy was performed in 5 patients; only emergency craniotomy (hematoma clearance) was performed in 3 patients; conservative treatment was performed in 1 patient. A small amount of diffuse bleeding with severe cerebral edema in the surgical region appeared in 2 patients, and the transient limb paralysis gradually recovered after 2 months of conservative treatment. Follow-up was performed for (4.5±1.7) years ([2.3-7.0] years). During the last follow-up, 4 patients were normal, 5 patients had mild to moderate hemiplegia, 1 had mild decreased vision in the right eye, and 1 had long-term coma. Epileptic control efficacy analysis indicated that 8 had Engel grading I and 3 grading II.Conclusion:Complete removal of hematoma and inactivated brain tissues can effectively control seizures and rebleeding in patients with hemorrhage resulted from cortical venous infarction.

Mineralized tissue regeneration is an important and challenging part of the field of tissue engineering and regeneration. At present, autograft harvest procedures may cause secondary trauma to patients, while bone scaffold materials lack osteogenic activity, resulting in a limited application. Loaded with osteogenic induction growth factor can improve the osteoinductive performance of bone graft, but the explosive release of growth factor may also cause side effects. In this study, we innovatively used platelet-rich fibrin (PRF)-modified bone scaffolds (Bio-Oss

Objective:To investigate the imaging and electrophysiological characteristics, surgical methods and efficacies of preschoolers with refractory temporal lobe epilepsy.Methods:A retrospective data study was conducted on 27 patients with refractory temporal lobe epilepsy accepted surgical treatment in our hospital from June 2014 to January 2019. By combined with clinical manifestations, preoperative epileptogenic zones were evaluated by imaging data, such as MR imaging, MR spectroscopy and positron emission tomography-CT, and interictal and ictal video-electroencephalogram (VEEG) data. During the surgery, cortical electroencephalography (ECoG) and deep electrode monitoring were used to monitor and locate the abnormal discharge areas to guide the surgical excision of epileptic zone. Engel grading was used to evaluate the efficacy after surgery.Results:All children had typical clinical manifestations of temporal lobe epilepsy; abnormal signal images were found in one side of the temporal lobe and the hippocampus in MR imaging; epileptic discharges were originated from one side frontotemporal region in interictal and ictal VEEG. Obviously persistent or paroxysmal spike waves, spike waves and slow spikes and spike composite waves were intraoperatively discovered by ECoG and depth electrode electroencephalography in the temporal lobe. All patients accepted standard anterior temporal lobectomy+lesion resection+peripheral abnormal discharge resection of the temporal lobe cortex; partial insular lobe was excised and frontal cortex was performed low power thermal coagulation in two patients. Follow-up was performed for 6 months; Engel grading I was reported in 22 patients (81.5%), Engel grading II in 3 patients (11.1%), and Engel grading III in 2 patients (7.4%).Conclusion:Early surgery and moderate extension of resection under intraoperative ECoG and deep electrode monitoring are the key factors to improve the surgical efficacy of preschoolers with refractory temporal lobe epilepsy.
