Case report on metastatic pelvic bone tumor treated with frozen autograft by liquid nitrogen.

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.

Fatal bilateral lower-limb deep vein thrombosis and pulmonary embolism following single digit replantation.

Hong Kong Med J 2015 Jun;21(3):283-5

Venous thromboembolism in hand surgery is rare. There is no report in the literature on postoperative mortality from venous thromboembolism following microsurgery in upper limbs. We report the case of a 56-year-old Chinese man who died from pulmonary embolism as a result of bilateral lower-limb deep vein thrombosis following prolonged surgery under general anaesthesia after replantation of a finger. This case raises awareness of the need for precautions against venous thromboembolism following prolonged microsurgery and identification of high-risk patients.
