Editorial Commentary: Dermal Allograft: A Viable Allograft for Salvage Procedures in Treating Irreparable Rotator Cuff Tears.

Our experience with superior capsule reconstruction (SCR) has been successful in patients with isolated, irreparable, supraspinatus tears; however, we have found that bridging reconstruction may have a better role in treating patients with some cuff remnant. Our results are promising, and, although there is new evidence to show that dermal allografts can heal in the setting of rotator cuff deficiency, the basic principle of restoring anatomy should not be ignored. SCR has been accepted as a salvage procedure for irreparable cuff tears, with the precise indications being elucidated. Reconnecting viable cuff muscle to tuberosity directly or through a graft should be considered before SCR.

Arthroscopic, Nonrigid Fixation of a Displaced Glenoid Fracture After Anterior Shoulder Dislocation.

Glenoid rim fractures are recognized as a risk factor for recurrent instability after anterior shoulder dislocation. In addition to traditional open treatments of bony Bankart lesions, several arthroscopic techniques of fixation and reconstruction recently have been described. We present a technique of arthroscopic nonrigid fixation for large glenoid rim fractures, as an alternative to existing procedures.

Arthroscopic Anatomic Glenoid Reconstruction in the Setting of a Failed Latarjet Using Distal Tibial Allograft.

Treatment of traumatic anterior glenohumeral dislocation has evolved over the years in terms of surgical approaches and methods of repair. Recurrence of instability following surgical repair remains challenging with conventional methods of open reconstruction. We describe the utilization of arthroscopic anatomic glenoid reconstruction using a distal tibial allograft after a failed Latarjet procedure. Preoperative and operative methodology are described with relevant imaging investigations and a detailed intraoperative arthroscopic technique.

Hip Arthroscopy for Femoral Acetabular Impingement: A Bird's-Eye/En Face Perspective With Ultrasound Guidance and 3-Dimensional Hip Printing.

Femoral acetabular impingement is a common hip disorder that may prove debilitating to many patients. Surgical management is indicated by way of hip arthroscopy for impinging CAM and pincer acetabular lesions. Traditionally, fluoroscopy has been used for the intraoperative assessment of bony resection; however, many disadvantages include radiation risks, equipment demands, and more. With ultrasound-guided arthroscopy, we describe the use of 1:1 3-dimensional hip printed models through various visual perspectives of impinging lesions. Given the low cost of 3-dimensional hip printing, lack of radiation exposure, and tactile multiangular views, we propose a safer and more reproducible intraoperative technique to conventional fluoroscopy to achieve better resection and outcomes after femoral acetabular impingement surgery.
