Apart from Subarachnoid block, combining lumbar plexus and sciatic nerve blocks has been a technique of prolonged interest to anaesthesiologists.
Surgical Anatomy of the Lumbar Plexus (online access included)
The lumbar plexus arises primarily from the ventral rami of L1-L4.
For TKA, nerves of lower limbs, including lumbar plexus-sciatic nerve and femoral-sciatic nerve, are mostly blocked.4 However, the lumbar plexus and sciatic nerve are located deeply, so patients should be kept in the lateral position and suffer from long surgical time even if nerve stimulator or ultrasonic assistance is used.

Additionally, the thoracic paravertebral space and lumbar plexus within the psoas muscle were not affected in all blocks regardless of approaches.
When we compare transpsoas approach, MIS-OLIF has several advantages such as less invasion of the psoas muscle and lumbar plexus, direct visualization of sensory nerves and important structures.
Motor or sensory deficits are the most common disadvantages of MISS, especially in lateral transpsoas approach, because the femoral nerve and the lumbar plexus nerve roots may be damaged during the operation.
The femoral and obturator nerves are the terminal nerves of the lumbar plexus that innervate the hip joint together with the lumbosacral trunk of the sacral plexus.
The femoral nerve is the largest nerve of the lumbar plexus, formed by dorsal divisions of the ventral rami of spinal nerves L2, L3 and L4 and innervates the anterior thigh muscles, hip and knee joints and the skin of the anteromedial thigh (Moore & Dalley, 1999).
