EDH is most often due to a fractured temporal or parietal bone damaging the middle meningeal artery or vein, with blood collecting between the dura and the skull. It is typically caused by trauma to the temple just beside the eye, although it may also follow a tear in dural venous sinuses. Children are less likely than adults to have an associated skull fracture. EDH in the spinal column may fo...

We reviewed the medical records of 233 patients having electrodiagnostic evidence of polyradiculopathy. Patients with polyneuropathy or incomplete diagnostic evaluation were excluded. A clinical diagnosis was secured in 92 of the 118 remaining patients. Patients were separated into three groups based upon the anatomic location of root involvement: extradural (55), intradural-extraaxial (23), an...

Thirty patients undergoing primary total hip replacement under lumbar extradural anaesthesia with 0.75% bupivacaine 25 ml were allocated randomly to receive either low-dose adrenaline or phenylephrine infusions i.v. throughout surgery. Haemodynamic measurements and arterial blood samples were obtained before the extradural injection and at 10, 20, 30, 40, 50, 60 and 90 min thereafter. Peak arte...

We have investigated in 10 patients the effect of extradural anaesthesia on temporal summation by comparing pain thresholds to single and repeated (five impulses at 2 Hz) electrical stimuli and compared these tests with pinprick and cold stimulation. Bupivacaine 0.5% (20 ml) was injected at L2-3. After extradural anaesthesia the threshold to repeated stimuli was significantly lower than the thr...

We have examined the effect of extradual injection of 0.5% bupivacaine or normal saline on the progression of spinal anaesthesia in 28 patients undergoing Caesearean section. Three groups were studied. Subarachnoid anaesthesia was established in all patients. Group A (n = 10), the control, received no extradural injection for 20 min. Group B (n = 9) received extradural bupivacaine 10 ml and gro...

We present a case of extradural hemorrhage, a rare and unusual complication associated with Sickle Cell Disease, from Nizwa, Oman. A 12-year old male child with Sickle cell disease (SD) was admitted to hospital with backache and pain in both lower Limbs. Clinical examination revealed an average built child with mild pallor, mild tenderness in the lower back and both legs. Rest of the examinatio...

Nerve sheath tumors are the most common spinal tumors but extradural foraminal nerve sheath tumors are much rarer. Traditionally, these nerve sheath tumors have been resected via an open posterior approach. We describe an alternative minimally invasive (MIS) lateral extracavitary approach for resection of symptomatic extradural foraminal spinal neurofibromas. We describe three consecutive male ...
