Craniocervical fixation is used for the treatment of instability owing to several pathological conditions. Initial operative techniques to stabilize the craniocervical junction involved onlay fusion. Onlay fusion is effective but…
Iliac fixation adds biomechanical strength in situations where the lumbosacral junction is exposed to high shear forces. Lumbopelvic fixation should be considered to reduce strain on the S1 pedicle screws…
Anterior cervical diskectomy and fusion (ACDF) is a safe and effective treatment for cervical spondylosis refractory to nonoperative management. Despite excellent results, concern remains about the decreased neck range of…
Surgical resection is the mainstay of treatment for intradural extramedullary (IDEM) spinal tumors such as meningiomas and nerve sheath tumors. 1 The goal of surgery is complete tumor removal, thereby…
Intraplexal or extraplexal nerve transfer (neurotization) procedures are being increasingly used as a management alternative for high-grade upper-extremity peripheral nerve injuries with outcomes that are either equivalent or improved compared…
Spinal stability is classically defined by White and Punjabi as the ability of the spine under physiologic loads to limit patters on displacement so that neither the spinal cord nor…
Techniques for achieving atlantoaxial fusion include posterior interspinous fusion with sublaminar cables and iliac crest bone graft ( ▶ Fig. 7.1), C1–2 transarticular screw fixation, and interlaminar clamp fixation. Although…
Before the popularity of lateral mass screws, posterior wiring techniques were the mainstay for posterior cervical spinal fixation. Initially, wiring was accomplished with monofilament stainless steel wire. Cable systems were…
Introduction and Patient Selection Lumboperitoneal (LP) shunting allows for extracranial management of hydrocephalus, cerebrospinal fluid (CSF) fistula, pseudomeningocele, and pseudotumor cerebri, thereby eliminating intracranial complications. LP shunts are also used…
Lumbar degenerative disease is a progressive process of disk and joint deterioration. As this pathology continues, it can lead to deformity of the lumbar spine. As a result of the…
