A Combination of Open Decompression and Percutaneous Pedicle Screw Fixation Ralph J Mobbs, MD1,2,3, Praveenan Sivabalan, MD2,3, Jane Li, MD2,3, Peter Wilson, MD1,2, Prashanth J Rao, MD1,2,3 Research The authors describe a hybrid technique that involves a combination of open decompression and posterior lumbar interbody fusion (PLIF) and percutaneously inserted pedicle screws. This technique allows […]

A Contrast-Enhancing Lumbar Ligamentum Flavum Haematoma Finn Ghent,1  Xuan Ye,1  Max Yan,2  Ralph J Mobbs1 Research We present a case of lower back pain with lumbar nerve compromise due to a ligamentum flavum haematoma which was successfully treated surgically. A 62-year-old man was evaluated for lower back pain with associated leg pain and early signs of cauda equina

A unique approach to fixed occipito-cervico-thoracic deformity G.E. Aw *, R.J. Mobbs1,2,3 Research We discuss a unique approach to a patient who presented with severe kyphosis and laterolisthesis of the cranio-cervico-thoracic spine, following a history of neck trauma 24 months prior to presentation. The patient had organized voluntary euthanasia if no treatment could be performed. Our

L5 En-Bloc Vertebrectomy with Customized Reconstructive Implant: Comparison of Patient-Specific Versus Off-the-Shelf Implant Ralph J Mobbs, MD 1,2,3,Mina Chung, MD2,Prashanth J Rao, MD1,3 Research The procedure of anterior lumbar interbody fusion (ALIF) is commonly performed on patients suffering from pain and/or neurological symptoms associated with disorders of the lumbar spine caused by disc degeneration and trauma.

Medio-Latero-Superior Trajectory Technique Ralph J Mobbs1,2,3 Research An alternative pedicle trajectory for use at the superior end of a construct to limit dissection of the mobile superior facet joint and reduce incision length and muscle dissection, thus minimizing approach-related trauma during pedicle fixation, is reported. The medio-latero-superior trajectory technique involves a starting point on the

Minimally Invasive Spinal Fusion Ralph Ralph J Mobbs1,2,3, Praveenan Sivabalan2,3*, Jane Li2,3 and Peter Wilson1,2 Research The authors describe a hybrid technique that involves a combination of open decompression and posterior lumbar interbody fusion (PLIF) and percutaneously inserted pedicle screws. This technique allows performance of PLIF and decompression via a midline incision and approach without compromising
