Rotator cuff repair in the setting of a chronic tear or poor tissue quality presents a surgical challenge because of the high risk of structural failure. Patients with an increased risk of retear may be candidates for enthesis augmentation with a novel, biphasic allograft, composed of a demineralized cancellous matrix with a layer of mineralized bone. This interpositional graft was designed with the intention to promote both soft-tissue and osseous integration into the matrix, thereby conferring greater stability and regeneration of the transitional zone of the rotator cuff enthesis. Here, we describe a technique for a transosseous-equivalent supraspinatus repair with placement of a biphasic interpositional allograft.
在慢性撕裂或组织质量较差的情况下进行肩袖修复，由于结构失败的风险较高，因此面临手术挑战。再撕裂风险增加的患者可能适合使用一种新型双相同种异体移植物进行附着点增强，该移植物由脱矿松质基质和一层矿化骨组成。这种插入式移植物的设计目的是促进软组织和骨组织与基质的整合，从而赋予肩袖附着点过渡区更大的稳定性和再生能力。在此，我们描述一种使用双相插入式同种异体移植物进行等效于经骨的冈上肌修复的技术。
