Superficial haematoma formation, seroma formation and infection are typically treated nonoperatively. Postoperative donor site pain can be avoided by careful handling of soft tissues, minimal subperiosteal dissection or stripping of pelvic muscles and anterior thigh musculotendinous attachments to the iliac crest and protection of sensory cutaneous nerves. Thus, an oblique incision is usually recommended. Sensory deficit to the superior two-thirds of the buttocks may occur. In posterior bone grafting, the superior cluneal nerves may be injured as they cross lateral to the posterior superior iliac spine.

Ilioinguinal neuralgia can occur by compression from the retractor against the iliac crest. This is more common with tricortical graft harvest. Long-term harvest site pain (3 months to 2 years) reportedly occurs in 2.5% of iliac crest bone grafting cases. Areas of concern include the face, iliac crests, lower ribs, patella and anterior ankle joints.

Adequate padding under pressure points can prevent skin and peripheral nerve complications especially in prolonged prone positioning. Injury to the common peroneal nerve can occur if the legs are placed in abduction and external rotation, which can cause pressure over the fibular head. Hanging the arm over the edge of the operating table can injure the radial nerve. Excessive traction with the tape or extension of shoulders below the coracoid process should be avoided to prevent compression of the brachial plexus. Arms are kept by the side and shoulders are usually pulled distally and taped to the operating table to facilitate lateral radiographs. Pressure over the eyeballs due to Mayfield headrest or Gardner Wells tongs should be avoided. This can result in ischaemic optic neuropathy, blindness and occipital stroke. Being in a prone position may increase intraocular pressure leading to ischaemia, decreased perfusion pressure and blood supply to the retina. Adequate head and neck control is mandatory to prevent damage to the spinal cord, such as skeletal traction via Halo ring or Mayfield tongs. Positioning the patient is important to permit access to the surgical field and is necessary to avoid pressure areas or iatrogenic injuries. The first step in handling any intraoperative drop in spinal cord signal/function is increasing the blood pressure. This is more apparent in cases of traumatic spinal cord injury where the patient may already have a contused and swollen spinal cord. Maintaining adequate blood pressure is important for neural perfusion. A mean arterial pressure of 65 mm Hg or 20 mm Hg below baseline in normotensive patients is usually safe. At least 65% of the usual spinal blood flow is required for physiological integrity and a 12% decrease in blood flow may produce paralysis. Unwanted effects include spinal cord ischaemia and neurological damage.

Manual inline axial stabilisation with fibre-optic nasal or oral endoscopy can reduce risk of spinal cord injury during tracheal intubation.Ĭontrolled hypotension reduces blood loss and facilitates surgical exposure. Forceful manipulation during laryngoscopy and tracheal intubation may jeopardise the spinal cord. During induction of general anaesthesia in patients with cervical instabilities, no protective mechanism exists for the compromised spinal cord due to the paralysed neck musculature. This is likely caused by trauma to the anterior soft-tissue and prolonged prone position both can result in upper airway oedema and impaired respiration. The reported incidence of postoperative respiratory compromise varies from 0%–14%.
