Résumé
Objective To investigate the method and effect of arthroscopic repair of recurrent anterior shoulder dislocation caused by anterior and inferior labrum complete defect.Methods Retrospective analyzed the clinical data of 23 patients with anterior and inferior la-brum complete defect who were admitted into hospital from June 2014 to October 2016 and recieved arthroscopic repair opreation with gleno-humeral ligament combined with articular capsule.Intraoperative arthroscopy was used to suture the lower glenohumeral ligament and articular capsule at the missing part of the glenoid labrum.The Rowe score,ASES score and UCLA score were compared before and after operation. Results There was no postoperative complications such as dislocation or infection occurred.All the 23 cases were followed up for 12~42 months,with an average of(19.6 ±3.4)months.The average lost angle of shoulder external rotation was(17.3 ±3.9)°.And the postopera-tive Rowe score,ASES score and UCLA score were significantly better than those before operation.Conclusion Arthroscopic repair opreation with glenohumeral ligament combined with articular capsule can effectively restore the stability of front shoulder joint,and it can be a good method for the treatment of recurrent anterior shoulder dislocation caused by anterior and inferior labrum complete defect.
Résumé
Objective To investigate the precision and clinical practicability of anchor point locating under the guidance of augmented reality (AR) navigation for anterior cruciate ligament (ACL) reconstruction.Methods A cube model was made by 3D print which contained some concentric circles of different diameters to be the target.Fifty orthopedists were chosen and numbered from 1 to 50 to locate with AR guidance.Finally,the results of precision and score of satisfaction were analyzed.Results The location precision guided by AR in different diameter concentric circle were 74% (0.25 cm),78% (0.5 cm),83% (0.75 cm),86% (1.0 cm),89% (1.25 cm),96% (1.5 cm) respectively.The average satisfaction score of the orthopedists' was (8.7 ± 1.3).Conclusion Anchor point locating under the guidance of AR navigation is a feasible and effect method for clinical ACL reconstruction,which can observe the relations of the anchor point and the adjacent structure in real time.
Résumé
Objective To explore the clinical effect of arthroscopic repair without traction for non-osseous Bankart injury.Methods From January 2009 to January 2015,the clinical data of 182 cases underwent arthroscopic Bankart repair for anterior shoulder instability in our hospital were analyzed retrospectively.They were aged from 18 to 39 years old,mean age was(26.5 ± 9.3) years.The course of disease was from 1 to 10 years,mean duration was(3.2 ±2.6) years.Recurrent dislocation was 6 to 62 times,with average of (24.2 ± 17.3) times.All cases were performed arthroscopic repair without traction.Rowes scores and UCLA scores were used for evaluation.Results All of 182 cases were followed up from 6 to 18 months,an average of (12.5 ± 6.7) months.Of the 182 patients,12 cases with postoperative limited 20°external rotation could not attend confrontational training and the other 170 cases had no adverse effect.The average loss of shoulder joint extorsion activity angle were (10.5 ± 4.1) °.Postoperative UCLA score (89 ± 3.5) was more than preoperative (25 ± 6.2),the differences were significant (P < 0.05).Postoperative Rowes score (28.7 ± 2.2) were more than preoperative (7.3 ± 1.6),the differences were significant (P < 0.05).Conclusion Curative effect of arthroscopic repair without traction for non-osseous Bankart injury caused by training is satifactory,which can provide brachial plexus,blood vessel and other tissues during surgery from traction,and be helpful to the popularization and application in basic-level hospitals.
