Due to the high-intensity pressure that the shoulder cuff endures, it is prone to traumas and tears. The main critical function of the shoulder cuff muscles is to effectively facilitate shoulder movement and securely maintain the humeral head in the precise center of the joint cavity to prevent superior migration during abduction processes. Shoulder cuff injuries typically involve the muscle-tendon-bone interface, but existing repair techniques do not always guarantee complete and secure healing, leading to retears. Hyperbaric oxygen therapy, as an auxiliary treatment, can significantly promote the muscle-tendon-bone healing process. To explore the impact of hyperbaric oxygen therapy on the bone-tendon interface healing process in a rabbit model specifically designed for shoulder cuff tears, an experiment was conducted on New Zealand white rabbits by performing a full-thickness tear of the supraspinatus tendon in the left shoulder, followed by 2 hours per day of 100% oxygen treatment at 2 absolute atmospheres for 5 days. The results indicate that hyperbaric oxygen therapy significantly enhances vascularization at the interface between the shoulder cuff and tendon-bone, promotes collagen fiber regeneration in the tendon, improves the tensile strength of the tendon-bone complex, and does not have a significant effect on biomechanical stability. This suggests that hyperbaric oxygen therapy has a significant positive impact on the histological and biomechanical healing of shoulder cuff tears in rabbits, expediting the healing process of the tendon-bone interface.
由于肩袖末端承受的高强度压力，它容易受到创伤和撕裂。肩袖肌肉的主要关键功能是有效地促进肩部运动，并将肱骨头安全地保持在关节腔内的精确中心位置，以防止在外展过程中向上迁移。肩袖损伤通常涉及肌肉-肌腱-骨界面，但现有的修复技术并不总是能保证完全和安全的愈合，导致再撕裂。高压氧治疗作为一种辅助治疗，可以显著促进肌肉-肌腱-骨的愈合过程。为了探讨高压氧治疗对兔模型肩袖撕裂特定设计的骨-腱界面愈合过程的影响，通过对新西兰白兔进行实验，在左侧肩部进行冈上肌腱全层撕裂，然后每天 2 小时在 2 个绝对大气压下接受 100%的氧气治疗，持续 5 天。结果表明，高压氧治疗显著增强了肩袖和肌腱-骨界面的血管生成，促进了肌腱中胶原纤维的再生，提高了肌腱-骨复合体的拉伸强度，对生物力学稳定性没有显著影响。这表明高压氧治疗对兔肩袖撕裂的组织学和生物力学愈合有显著的积极影响，加速了肌腱-骨界面的愈合过程。
