This is a a simplified alternative to conventional microscope. Space utilisation and surgeon's fatigue factors are minimised. Courtesy: Sunil Verma - Storz

Discal cysts clinically simulate IVDP. MRI differentiates by hypointensity in T1 and hperintensity in T2. Pathogenesis is debatable. It could be due to a resolving haematoma in an injured disc or a degenerative mechanism similar to ganglion cyst. Surgical decompression is the treatment.

This cranioplasty implant was anchored with silk suture which gave way due to constant impinging force of brain pulsation. This is better avoided by anchoring the cranioplasty implant with titanium mini plates and screws or titanium wires.

Excision of spinal intradural extramedullary neurofibroma gives excellent results. Early detection facilitates recovery pattern.

After corpectomy, I feel that Synmesh which has the lids to "bottle up" bone graft pieces as the technically least challenging instrumentation.

Ravi Rectangle in CVJ stabilisation is a useful tool in centres with limited facilities (like.. No Image Intensifier)

These instruments were in practice in the long past. Please read the inset for the details of the instrument

Infected Cranioplasty. Dandruff infestation was the forerunner leading to secondary infection. Implant has been removed.

Ravi Rectangle serves as one unit avoiding use of rods and transverse connector and offers better stability as one unit

Translaminar stabilisation of spinal instability using Ravi Rectangle where spinal canal compromise is to be avoided(as in sublaminar wiring)

One of the rare causes of acute onset paraplegia. Immediate intervention and evacuation of pus gives reasonable result

Scalloping of vertebral body

Phenytoin Toxicity

Exposed Shunt Tube leads to meningitis

Haemangioma of skull. Total excision is the rule.

Secondaries in skull from bronchogenic carcinoma

Multiple Intracerebral lesions. ?cysticercosis ?tuberculomata

Migrated rod in pedicle screw fixation system is not very common.

Chronic subdural haematoma after excision of Arachnoid cyst in the same location

This is a recurrence after microscopically total excision.

Diploic meningioma projecting intra and extracranially. Total excision is always achieved.
