To develop a new classification of acromion based on the subacromial impingement theory and the Rockwood tilt view. And explore the application value of the new classification in the diagnosis and treatment of rotator cuff tear.

The clinical data of 101 patients underwent shoulder arthroscopic surgery for impingement syndrome or rotator cuff tear from January to December 2017 were retrospectively analyzed. There were 34 males and 67 females, aged from 34 to 76 years with an average of (56.31±9.63) years old, course of disease from 2 to 12 months with average of 6 months. Preoperative radiographs of the routine anteroposterior view, Rockwood tilt view and the supraspinatus outlet view were obtained. Muvalaplin inhibitor Based on the subacromial impingement theory and Rockwood radiographs, the morphology of the acromion can be divided into three typestypeⅠ(flat type), typeⅡ(bump type), and type Ⅲ (impingement type). Two observers classified 101 shoulder Rockwood radiographs according to the new classification method and the supl classification and AHD, the new classification method has more diagnostic value than for rotator cuff injury.
Rockwood radiographs of the shoulder can well display the anterolateral osteophytes of the acromion. The new acromion classification method based on Rockwood radiographs has high reliability and good reproducibility, in which impingement type of acromion is closely related to supraspinatus tendon tear. Compared with the traditional classification and AHD, the new classification method has more diagnostic value than for rotator cuff injury.
To explore the clinical effect of Kirschner wire retractor-assisted reduction and inverted insertion of elastic nail in the treatment of children's irreducible subradial 1/3 fractures.

A total of 34 children with irreducible subradial 1/3 fractures treated by surgery from August 2016 to December 2020 were retrospective analyzed. Among them, 16 cases underwent Kirschner wire retractor-assisted closed reduction and percutaneous elastic intramedullary nailing with inverted insertion(observation group), 10 males and 6 females, aged from 4 to 10 years old with an average of(6.0±0.4)years;18 cases underwent open reduction and plate internal fixation (control group), 11 males and 7 females, the age from 3 to 10 years with an average of(7.0±0.5) years. The operation time, intraoperative blood loss, hospital stay, incision length, fracture healing time and complications of the two groups were observed and the wrist function was evaluated by Cooney wrist joint score.

All patients were followed up for 3-12 years osisted reduction and percutaneous elastic intramedullary nail fixation for irreducible subradial radial 1/3 fractures has the advantages of less trauma, shorter operation time, less blood loss, and satisfactory short-term clinical results.
To observe the radiological change and curative effect of cervical spondylosis treated with cervical vertebra pulling therapy in young people.

A total of 65 patients(shedding in 5 patients and final inclusion in 60 patients) with cervical spondylosis who were treated from January 2018 to September 2019 were randomly divided into treatment group and control group according to the digital table method. There were 30 patients in treatment group, including 14 males and 18 females, aged from 20 to 44 years old with an average of(29.83±6.99) years, who were treated with cervical vertebra pulling therapy(once a week, 4 times in total). The control group consisted of 30 cases, 12 males and 18 females, aged from 18 to 43 years old with an average of (31.77±5.93) years, who received sitting traction therapy(once a week, 4 times in total). The changes of C

To investigate the short-term clinical effect of the cervical anterior Hybrid surgery in the treatment of two-segment and three-segment cervical spondylosis.

From January 2018 to January 2019, 108 patients who were performed anterior Hybrid surgery with cervical degenerative diseases were collected. The patients were divided into a two-segment group with 52 patients and a three-segment group with 56 patients according to surgical segments. In two-segment group, there were 24 males and 28 females, aged from 35 to 67 years old with an average of(45.94±14.67) years old. In three-segment group, there were 23 males and 33 females, aged from 32 to 65 years old with an average of (47.54±15.34) years old. The outcome indicators of the two groups were compared. Clinical indicatorsneck disability index(NDI) was used to evaluate daily life ability, Japanese Orthopedic Association(JOA) score was used to evaluate neurological function improvement, visual analogue scale(VAS) was used to evaluate pain intensity, and genrove clinical symptoms of patients but also preserve mobility. Meanwhile, the efficacy and safety of Hybrid surgery in different multi-level cervical disc diseases are confirmed, proving its value in clinical practice.
To explore the effects of different administration methods of tranexamic acid(TXA) on the perioperative blood loss, hidden blood loss, transfusion rate and adverse reactions in lumbar spinal decompression and fusion.

Sixty patients who received lumbar spinal canal decompression and fusion from July 2019 to July 2020 were enrolled and divided into observation group and control group, with 30 cases in each group. The observation group was given 2 g TXA orally at 2 hours before operation, control group was given 1 g TXA for 5-10 min before skin incision and 6 hours after operation intravenously. The intraoperative blood loss, postoperative drainage, total blood loss, hidden blood loss, drainage tube removal time, blood transfusion rate, venous thrombosis rate, adverse event rate were recorded respectively. The changes of hemoglobin(Hb) and hematocrit (HCT) were observed before operation and 1, 3 days after operation.

Hb and HCT at 1 and 3 days after operation were significantly improved compared with those before operation(
<0.01). However, there was no significant difference between the groups(
>0.05). There were no significant difference in amount of blood loss, postoperative drainage, total blood loss, intraoperative blood loss, hidden blood loss, postoperative drainage time, and blood transfusion rate between two groups (
>0.05). There were no venous thrombosis and adverse events occurred in both groups.

During the perioperative period of lumbar spinal decompression and fusion, oral TXA and intravenous TXA have the same effect in reducing perioperative blood loss and are safe and reliable. It is recommended that oral TXA be used to save medical costs and convenience.
