Bankart injury of the shoulder joint is defined as an avulsion of the glenohumeral ligament and glenoid labrum complex from the anterior attachment of the shoulder glenoid, accompanied by rupture of the anterior scapular neck periosteum and the development of a distinct gap between the scapular glenoid and the glenoid labrum. Anterior dislocation of the shoulder is a common cause of Bankart injury and recurrent anterior instability of the shoulder. Recurrent anterior dislocation of the shoulder is common in clinical practice, whereas posterior dislocation is only 2-4%. The shoulder capsule-ligament-glenoid labrum complex is an important structure that stabilizes the shoulder joint, and its anterior stability is often compromised when it is involved. The pathologic changes include capsular laxity, bony changes in the humeral head (e.g., Hill-Sach injury), and glenoid labral damage, of which glenoid labral injury is the most important pathologic basis, and the location and extent of glenoid labral injury directly affects the surgical approach and method. Gartsman observed a slightly different outcome in the repair of rotator cuff injuries with and without combined glenohumeral intra-articular pathology. Depending on the direction and magnitude of the force of the injury, the lesion could occur at three different sites, including the attachment of the joint capsule to the glenoid, the joint capsule tissue itself, and the joint capsule attachment to the humeral neck. Injuries to the shoulder pelvis account for 74%, the joint capsule itself for 17%, and the humerus for 9%. The anterior labral ligament cuff tear (ALPSA) is identical to the Bankart injury, with the only difference being that Bankart tears the periosteum at the scapular neck, whereas the ALPSA periosteum is unbroken and peels intact along the bone surface, allowing the complex to peel away and rotate inward and downward in a floating fashion. In old lesions, this exfoliation has been filled with fibrous tissue and becomes a fold that sinks below the shoulder glenoid rim. In bony Bankart injuries, the bone anterior or inferior to the shoulder glenoid is pulled down when the ligament-glenoid labrum complex is avulsed. Leigh imaging is of great clinical value in the diagnosis of shoulder instability. Shoulder arthrography or MRA reveals leakage of contrast through the torn glenoid labrum to the subscapularis muscle.CT has high accuracy and specificity in the diagnosis of bony Bankart injury.Articular glenoid labral injury presents as a low-density soft tissue shadow that breaks or disappears at the glenoid attachment with a small avulsed fracture mass on CT scan angiography (CTA).CTA is considered to be the most accurate way to diagnose articular CTA is considered to be the simplest and ideal method to diagnose injury to the capsule-glenoid labrum complex. Normal MRI scans show high intensity signal in fat and cancellous bone, moderate intensity signal in muscle, low intensity signal in tendon, glenoid labrum, and cortical bone, and moderate intensity signal in T1-weighted images and low intensity signal in T2-weighted images of glenoid cartilage. Injury to the glenoid labrum shows increased signal between the glenoid labrum and the glenoid rim, and blunt displacement, complete disappearance, or calcification of the triangular glenoid labrum. In MRA, in addition to the same presentation as MRI, the contrast is more intense and contrast leakage between the glenoid labrum and hyaline cartilage is seen through the injury. 1987 Hajek et al. contrast MRI (MRA) technique has a higher sensitivity and specificity compared to CTA. The positive accuracy of MRA, CTA, and MRI in diagnosing joint capsule-glenoid labral complex injury has been reported to be 90%, 89%, and 82%, respectively. Arthroscopic repair of Bankart injury with an absorbable Bankart nail and repair of anterior instability of the shoulder joint is the key to prevent and treat anterior dislocation of the shoulder joint. With the advancement of arthroscopic techniques, arthroscopic repair of anterior shoulder instability has a tendency to gradually replace open surgery to repair anterior shoulder instability. Arthroscopic examination reveals yellow staining of synovial tissue, which is caused by old bleeding after shoulder dislocation and iron-containing heme deposition. The shoulder capsule-a ligament-a glenoid lip complex was separated and displaced from the shoulder glenoid, and an obvious sulcus-like fissure was formed between them, and the anterior joint capsule and ligament tissues were lax. The injury site was located at the 2-5 o’clock position on the right shoulder and more at the 8-11 o’clock position on the left. After confirmation of the lesion site, radiofrequency or planing was performed to clean up the trauma and scar tissue of the Bankart injury, and an angular file was inserted between the shoulder pelvis and the joint capsule-ligament-a glenoid labrum complex for stripping, resulting in a fresh trauma for healing until the bone surface of the shoulder pelvis was bleeding, and the shoulder joint capsule-a ligament-a glenoid labrum complex was drawn toward the glenoid labrum edge, and a 2-mm diameter Kirschner needle was used to pass through and The rivet is driven into the bone with a 2.5 mm diameter drill bit, and the absorbable anchor nail is driven into the bone along the guide pin, close to the glenoid labrum, and then the rivet is driven into the bone with a drill, and the tooth-like protrusion under the nail will hold the shoulder capsule, ligament, and glenoid labrum firmly in place at the glenoid labrum. Depending on the size of the injury, 2-3 rivets are usually inserted. The stability of the shoulder joint is checked postoperatively. In the absorbable anchor nail fixation method, the shoulder glenoid and capsule are cleaned and the anchor nail is fixed to the shoulder glenoid injury through a working cannula along the guide pin under arthroscopic surveillance. Pagnani et al. reported bioresorbable rivet (Acufes) fixation for type II and IV SLAP lesions with satisfactory results in 86% of 22 patients, and Warner reported good results with bioresorbable nails (Surtac) for SLAP lesions with Bankart lesions (type V). However, the resorbable rivets are gradually resorbed over time, and the potential osteolysis problems associated with them have not been fully resolved. The surgical application of a periosteal stripper to dissect the glenoid, lift the glenoid labrum tissue to separate the injured capsule, and use a planer to remove scar tissue until there is fresh bleeding from the exposed glenoid bone to achieve adequate release and preparation of the glenoid and glenoid labrum to create a “bone bed” with blood flow to allow the glenoid labrum to heal; the The composite is retracted to the glenoid labrum and the guide pin is inserted under the fixation of the guide. The depth and correct angle of the guide pin should be sufficient to enter the shoulder glenoid bone, otherwise the hollow drill will bring out the guide pin after entering and affect the operation. The nail path should reach a certain depth so that the anchor nail is not obstructed when it is placed and the anchor nail is broken.
