Introduction And Importance: Frozen autograft recycling has been used for biological reconstruction of bone defects following tumor excision, more commonly in extremities. We report on the histological outcome of a pelvic recycled frozen autograft.
Case Presentation: We investigated the pelvic frozen autograft removed in 2 years and 8 months after surgery because of soft tissue recurrence in pelvic floor. The autograft bone showed no evidence of revitalization and was non-viable with patchy inflammation, and no residual tumor. There was only fibrous union but the autograft bone remained mechanically stable.
Clinical Discussion: We confirmed the clearance of tumor cells with the treatment with liquid nitrogen. The union at the host-graft junction might be affected by the previous radiotherapy, the presence of infection, the small contact area limited by the anatomy, and the inadequate compression across the osteotomy interface with the fixation.
Conclusion: Frozen autograft treated by liquid nitrogen can be used safely for biological reconstructions after pelvic tumor excision.

Purpose: To biomechanically evaluate a flat posterior cruciate ligament (PCL) reconstruction utilizing rectangular femoral bone tunnels.
Methods: Eight fresh-frozen human knee specimens were tested in a six-degrees-of-freedom robotic test setup. In each testing step, a force-controlled test protocol was performed, including 89 N posterior tibial translation (PTT) in neutral, internal and external rotation, from 0 to 90° of flexion.

Managing patients with severe fixation of intra-abdominal contents, known as frozen abdomen, often creates a vicious cycle of tissue injury that further prolongs open abdomen resolution. We share the management course of a 28-year-old male status post motor vehicle accident with traumatic pancreatitis and complex liver injury. Following multiple laparotomies for abdominal wash out, he developed a frozen abdomen and an entero-atmospheric fistula (EAF) through granulated bowel.

Purpose: This study aims to compare the clinical outcomes of intercalary frozen autograft and allograft reconstruction for primary malignant bone tumors.
Methods: A retrospective study was conducted on 144 patients who underwent intercalary biological reconstruction for primary malignant bone tumors at a single institution between January 2012 and July 2023. Seventy-two patients underwent intercalary liquid nitrogen-frozen autograft reconstruction, and 72 patients underwent intercalary allograft reconstruction in this study.

Importance: Ovarian tissue cryopreservation (OTC) is an innovative and established fertility preservation method. More than 150 live births have been reported worldwide to date with the use of this strategy. OTC is one of the options to preserve fertility in prepubertal girls and for women who have time constraints and/or contraindications for ovarian stimulation for oocyte/embryo freezing before cancer treatment.

Aims: We analysed the survival, complications, and function of frozen autograft augmented with intramedullary cement and bridging plates fixation for intercalary bone defect reconstruction in primary bone sarcomas.
Patients And Methods: A retrospective cohort study was conducted on 72 patients with primary bone sarcomas (34 males, 38 females) between January 2016 and June 2023. The average age was 22.
