  • RESEARCH PROGRESS IN INFLUENCE OF BONY STRUCTURE OF GLENOHUMERAL JOINT ON SHOULDER JOINT STABILITY

    Objective To review the progress in influence of bony structure of glenohumeral joint on the shoulder joint stabil ity. Methods Recent l iterature, concerning the influence factors of the shoulder joint stabil ity and the action of bony structure of the glenohumeral joint in the stabil ity of shoulder joint, was extensively reviewed and summarized. Results The specific factors which the bony structure of the glenohumeral joint influences the stabil ity of the shoulder joint are the conformity index, the shape of the glenohumeral joint, version angle, incl ination angle, and head shaft angle, etc. Conclusion Although the predecessor’s research experience and cl inical reports have prel iminarily determined therelationship between the bony structure of the glenohumeral joint and the stabil ity of the shoulder joint, it is necessary to further study in various aspects (including anatomy, biomechanics, and cl inical practice).

  • BIOMECHANICAL EVALUATION OF GLENOHUMERAL LIGAMENT IN HOLDING ANTERIORSTABILITY OF SHOULDER JOINT

    ObjectiveTo investigate the effect of glenohumeral ligament(GHL) in static stabilizing structure of shoulder joint. Methods Fifteen upper limbs specimen from fresh adult corpse were made shoulder jointbone ligament specimen and divided in 5 groups (n=3). The loadshift curve of the following specimen was measured respectively at the shoulder joint in abductive angles of 0°,45° and 90°,influenced by 50 N posterioranterior load to evaluate anterior stability of shoulder joint. According to different selectivecutting test, 5 groups were divided subgroups:group A (A1-A4), respectively normal group, superior GHL (SGHL) injury group;SGHL/middle GHL (MGHL) injury group and SGHL/MGHL/inferior GHL (IGHL) injury group; group B(B1-B3),respectively normal group,MGHL injury group,MGHL/IGHL injury group; group C(C1-C2),respectively normal group,IGHL-anterior band(IGHL-AB) injury group; group D(D1-D2),respectively normal group, IGHL-posterior band(IGHL-PB) injury group; and group E(E1-E2),respectively normal group, IGHL injury group. Results For complete shoulder joint(A1 group), there was verysmall average shift (15.00±4.99 mm), for A4 group, there was the worst stability of shoulder joint,the average shift was 22.34±5.70 mm. For B2 group,the stability of shoulder joint had no obvious decrease. For B3 group, the stability of shoulder joint was worst at abduction angleof 45° and 90°. For C2 group, the stability of shoulder joint at abduction angle of 45° (23.19±4.58 mm) and 90°(15.32±1.30 mm) was worse than that of A1 group (P<0.05); halfdislocation or dislocation could be seen. For D2 group(17.30±4.93 mm), there was less effect on anterior stability of shoulder joint than that of A1 group(P<0.05).For E2 group(20.26±4.75 mm), the effect on anterior stability was similar toC2 group. Conclusion GHL is a key static stabilizing structure of shoulder joint. SGHL has no obvious effect on anterior stability of shoulder joint. MGHL and IGHL together holds anterior stability of shoulder joint, and IGHL plays the most important role.

  • The efficacy and safety of different site corticosteriod injection for patient with frozen shoulder at early stage

    Objective To evaluate the efficacy and safety of different site injection of compound betamethasone injection, ropivacaine and sodium hyaluronate for treatment of frozen shoulder at early stage. Methods A Total of 68 participants were included from May 2015 to May 2017 and randomly assigned to the glenohumeral joint and subacromial space group (IA+SA group, n=34) and glenohumeral joint group (IA group, n=34). In the IA+SA group, a solution of 1 mL corticosteroid, 6 mL ropivacaine, 2 mL sodium hyaluronate, and 8 mL normal saline were prepared and injected to glenohumeral joint, and a solution of 1 mL corticosteroid, 2 mL ropivacaine, 2 mL sodium hyaluronate, and 2 mL normal saline were injected to subacromial space. In the IA group, participants were given the same dose of drugs to the glenohumeral joint. The Visual Analogue Scale (VAS) score and Constant-Murley score were used to assess pain and function of shoulder respectively. The change of VAS score and Constant-Murley score after treatment were used to evaluate pain relief and shoulder function improvement. Results Of the 68 participants, two in each group were lost to follow up and one in the IA+SA group dropped out. There was significant effect on pain relief and shoulder function improvement on all measurement in both groups (P<0.001) during the 12 weeks after treatment. In the IA group, group- by-time interaction were significant for pain relief at 6 and 12 weeks comparing with that at 3 weeks (P<0.001), while no significant difference at 6 weeks comparing with 12 weeks. In the IA+SA group, group-by-time interaction were significant for pain relief at all endpoints (3 weeksvs. 6 weeks: P<0.001; 3 weeksvs. 12 weeks: P<0.001; 3 weeksvs. 6 weeks: P=0.034). In both groups, there was significant effect on shoulder function improvement when compared at each endpoint within group (P<0.001). Between-group comparison revealed no significant effect on pain relief (P=0.386) or shoulder function improvement (P=0.685). There was also no significant effect on pain relief (3 weeks: P=0.898; 6 weeks: P=0.448; 12 weeks: P=0.216) and shoulder function improvement (3 weeks: P=0.120; 6 weeks: P=0.152; 12 weeks: P=0.868) at each same endpoint. Conclusions Different site injection can effectively release pain and improve shoulder function for the patients with frozen shoulder at early stage and be well tolerated. However, it is not found that two site injection is inferior to single site injection.

  • Interpretation of 2020 American Academy of Orthopaedic Surgeons (AAOS) on the Management of Glenohumeral Joint Osteoarthritis Evidence-Based Clinical Practice Guideline

    The 2020 Management of Glenohumeral Joint Osteoarthritis Evidence-Based Clinical Practice Guideline which was prepared by the American Academy of Orthopaedic Surgeons (AAOS) were publicated on October 2020. The guideline involves the following 8 chapters: drug therapy and injectable biologics, physical therapy and non-surgical treatments, radiographs, prognostic factors, surgical treatments, intraoperative hemostasis measure (tranexamic acid), management of supraspinatus tears, multimodal pain management and discharge. In this paper, the guideline is interpreted to provide cutting-edge information for domestic glenohumeral joint osteoarthritis researchers.
