RESUMO
Objective To assess the effectiveness of Bankart repair under arthroscope in treatment of recurrent anterior shoulder joint instability. Methods From February 2010 to February 2015, 63 patients with recurrent anterior shoulder dislocation under arthroscipic Bankart repair, and 53 patients (28 male, 25 female) were available for follow-up. The mean age at the time of surgery was 27.9 years (range, 16 ~ 51). All of the 63 patients underwent surgical treatments, and the effectiveness was evaluated with University of California at Los Angeles (UCLA), American Shoulder and Elbow Surgeon scores (ASES), Constant-Murley scores, forward elevation, abduction and external rotation and X-ray. Results The ASES scores, UCLA scores were (97.0 ± 6.8), (29.6 ± 2.5) respectively, improved significantly higher after the surgery (P < 0.05). No significant change was found regarding Constant-Murley scores (99.1 ± 2.4), forward elevation (168.7 ± 2.7)°, abduction and external rotation (72.6 ± 8.7)° compared with the pre-operation. Conclusions Significant difference between pre-operation and post-operation suggests that Arthroscopic Bankart repair is a good option for the treatment of recurrent anterior shoulder dislocation without large glenoid bone loss and poor quality Ligament and joint capsule. Risk factors of recurrence should be evaluated before the surgery to reduce the recurrence rate of dislocation.
RESUMO
Based on the digital and network environment, this paper analyzes the problems existing in the teaching of traditional orthopedics in medical colleges and universities, including single teaching form, neglecting the students' practical skills and the phenomenon of students' poor learning initiative. It points out that the orthopedics teaching under the digital and network environment should be integrated through interactive teaching, multimedia teaching, WeChat network teaching, simulation teaching, practice teaching and other teaching forms and should pay attention to the reasonable use of teaching methods, make clear teachers and students' subject status, pay attention to students' learning ability training, so as to improve the teaching quality of orthopedics in medical colleges.
RESUMO
BACKGROUND:Studies have shown that factors affecting the outcomes of anterior cruciate ligament reconstruction mainly depend on the position of bone tunnels. However, there stil exists certain controversy over the researches on the position of bone tunnels. OBJECTIVE:To investigate the clinical value of three-dimensional computed tomography on postoperative evaluation of bone tunnel after anterior cruciate ligament reconstruction under arthroscopic assistance. METHODS:Fifty-eight patients with anterior cruciate ligament injury who received the treatment from January 2014 to August 2014 underwent anterior cruciate ligament reconstruction under arthroscopic assistance. The femoral end was fixed using an Endobutton, and tibial end was fixed using absorbable interference screws. 58 knees from patients were scanned respectively by means of a dual-source CT scanner. A three-dimensional model of knee was rebuilt on a CT image post-processing workstation to reproduce the medial wal of the lateral femoral condyle and reconstruct single-bundle anterior cruciate ligament, tibial plateau and bone tunnel. The cases that had a Lysholm score≥ 80 points were included in the excelent and good group and those who had a Lysholm score 0.05). These results confirm that three-dimensional computed tomography can help to clearly reconstruct the images of bone tunnel and anterior cruciate ligament grafts after operation, which can be used clinicaly to assess the relationship between bone tunnel location and graft misshaping.
RESUMO
BACKGROUND:There is a controversy in the clinical anterior cruciate ligament reconstruction using autologous hamstring tendon or tendon alograft. OBJECTIVE:To compare the clinical results of anterior cruciate ligament reconstruction with tendon alograft and autograft. METHODS: Totaly 123 patients with injured anterior cruciate ligament received anterior cruciate ligament reconstruction and they were divided into two groups: 63 cases in autograft group and 60 cases in alograft group. The postoperative effects were assessed by the Lysholm score and Lachman test. RESULTS AND CONCLUSION: Al the patients were folowed for more than 8 months. After anterior cruciate ligament reconstruction, the stability of the knee joint, Lysholm scores and Lachman test results were al improved significantly in the two groups; while there was no difference between the two groups at the last folow-up (P > 0.05). The clinical outcomes of anterior cruciate ligament reconstruction with alograft and autograft are almost similar; therefore, surgeons should select ideal graft according to the patient’s condition and surgeon’s experience.
RESUMO
BACKGROUND:It is stil disputed about the treatment of subacromial impingement syndrome at present, arthroscopic subacromial decompression or open subacromial decompression. OBJECTIVE:To assess the clinical therapeutic effects of arthroscopic subacromial decompressionversus open subacromial decompression in the treatment of subacromial impingement syndrome. METHODS:Controled trials on arthroscopic subacromial decompressionversus open acromioplasty in the treatment of subacromial impingement syndrome were colected in different databases through computer search. There was no limitation for language, randomized controled trials or blinded studies. At last, the meta-analysis was conducted by using RevMan5.0 software. RESULTS AND CONCLUSION:Four randomized controled trials and six non-randomized controled trials were included in this study, involving 583 patients with subacromial impingement syndrome. The results of meta-analysis prompted that as to the hospital inpatient days and time until return to work, the group of arthroscopic subacromial decompression was shorter than open subacromial decompression. However, as to the postoperative shoulder functional scores, the operative time, patient’s satisfaction, and the rate of excelent and good results of postoperative UCLAs, there were no significant statistical differences between two groups. Due to the certain limitations and deficiencies of the quantity and quality in the included trials, there must stil need large-sample, multi-centered, high-quality randomized controled trials to confirm these results.
