Juxtafacet cysts are an uncommon cause of radiculopathy. They occur most frequently in the lumbar region, and their distribution across the spine correlates with mobility. Haemorrhagic complications are rare and may occur in the absence of any provocation, although there is some association with anticoagulation and trauma. We present a case of acute radiculopathy due to an L5/S1 juxtafacet cyst with unprovoked haemorrhage which was found to extend into ligamentum flavum. The patient underwent uncomplicated microscope assisted decompression with excellent results. The demographics, presentation, aetiology, and management of juxtafacet cysts are discussed. 1. Case Report A 77-year-old female was referred with a 2-month history of sudden onset left leg pain fitting an S1 radiculopathy. There was a long history of mild lower back pain. There was no history of traum...

Results: In addition to its traditional role in the treatment of diving medicine, there is increasing evidence of the role of HBOT in improving wound healing, neovascularisation, decreased inflammatory responses, reduced tissue hypoxia and potentiation of chemotherapy. A review over the past thirty years demonstrates good evidence for the efficacy of HBOT in the treatment of fracture non-union, chronic non-healing wounds, chronic osteomyelitis, radiation tissue injury and acute traumatic ischaemia. However, multicenter randomized controlled trials for these indications are often lacking. More limited, but promising, research exists for its potential efficacy in the treatment of primary bone cancer, compromised grafts, avascular necrosis, necrotizing fasciitis and gas gangrene. Conclusion: The use of Hyperbaric Oxygen Therapy is an exciting new frontier in the treatment of many challenging orthopaedic conditions. In Australia, the mechanisms and uses of HBOT are often poorly appreciated by surgeons, with limited access to chambers and cost also restricting its use. It is hoped that this review will illuminate the potential uses of HBOT for many orthopaedic conditions and encourage further research into its role.
