Postoperative infection and bone sarcoma survival: systematic review of the role of infection in bone sarcoma prognosis.

Background: Osteosarcoma (OS) and chondrosarcoma (CS) are primary bone malignancies whose prognoses have stagnated despite advancements in surgical management, chemotherapy, radiation therapy, and immunotherapy. The role of the immune system in generating anti-cancer physiologic responses is critical to prognosis. Prior studies have explored if immune system activation via infection enhances survival in bone sarcomas without a clear consensus.

Increased Failure Rates After Arthroscopic Bankart Repair After Second Dislocation Compared to Primary Dislocation With Comparable Clinical Outcomes.

Purpose: The purpose of this study was to compare rates of recurrent dislocation and postsurgical outcomes in patients undergoing arthroscopic Bankart repair for anterior shoulder instability immediately after a first-time traumatic anterior dislocation versus patients who sustained a second dislocation event after initial nonoperative management.

Methods: A retrospective chart review was performed of patients undergoing primary arthroscopic stabilization for anterior shoulder instability without concomitant procedures and minimum 2-year clinical follow-up. Primary outcome was documentation of a recurrent shoulder dislocation.

The Effectiveness of Preoperative Antibiotic Prophylaxis in Ulnar Nerve Release at the Cubital Tunnel.

Background: Although the literature supports not using preoperative antibiotic prophylaxis for clean soft tissue procedures around the hand, there is limited data for soft tissue procedures around the elbow, such as cubital tunnel release. Complications of postoperative infection include scarring, stiffness, and rarely, amputation. The purpose of this study is to determine if preoperative antibiotic prophylaxis decreases the risk of surgical site infection for cubital tunnel release.

Use of L5-S1 transdiscal screws in the treatment of isthmic spondylolisthesis: a technical note.

Surgical treatment of L5-S1 isthmic spondylolisthesis consists of a combination of decompression and fusion. One previously discussed mode of fusion is via transdiscal screws. Biomechanical studies of transdiscal screws have demonstrated greater rigidity than traditional pedicle screw fixation, which theoretically translates to a higher fusion rate.
