Sciatic nerve : - Origin – it originated from L4,l5,s1,s2,s3 Lumbosacral Plexus Courses - it leaves the pelvis and enters the gluteal region via greater sciatic foramen. It emerges inferiorly to the piriformis muscle and descends in an inferolateral direction. Termination – In the middle of the Back Of the thigh. It divided into
Two terminal branch- tibial nerve and common peronial nerve. MuscleS SuppLIed by SCIATIC NERVe – SemiTendinoSus, semimemBranosus, long and short head of biceps femoris, adductor magnus. Sensory supply- posterior Aspect of thigh
Definition Sciatic Nerve Injury can occur due to trauma (pressure, stretching or cutting) to the nerve. This type of injury can cause degrees of muscle power loss and altered sensation.
CAUSES Spinal stenosis Spondylolisthesis Piriformis syndrome Gunshot Any trauma that leds to hip dislocation and acetabulam fracture 6. Injection pAlsy
7. Total hip joint replacement
Sign and SymPtom Weak flexion of knee
Foot drop
Wasting Of cuff muscle
Loss of achilis tendon Reflex Trophic ulcer
Sensory loss below the knee (except the area supplies by sAphenous Nerve) 7. Sciatica – pain along the posterior aspect
Of thigh
Management Non surgical management – 1. Nsaids can use for Reduced pain, inflammation, Swelling 2. Physical therapy : The goal of physical therapy is to find exercise movements that decrease sciatica by reducing pressure on the nerve. An exercise program should include stretching exercises and aerobic exercises (such as walking, swimming, water aerobics)to improve muscle flexibility. 3 .Spinal injections : An injection of a corticosteroid, an anti-inflammatory medicine, into the lower back might help reduce the pain and swelling around the affected nerve roots.
Cont…… Surgical management – 1. Laminectomy- It is most commonly done for sciatica pain caused by lumbar spinal stenosis .
Cont… Microdiscectomy: This is a minimally invasive procedure used to remove fragments of a herniated disk that are pressing on a nerve.
Cont…. Urgent surgically reduction of Hip dislocation
Proper treatment of Fracture
Open wound repaiR
A drop foot splint can be fitted
