Young
A 65-year-old man with a long-standing history of type 2 diabetes presents to the clinic with complaints of weakness in his proximal lower limbs. He reports particular difficulty in getting up from a squatting position. On examination, you notice significant muscle wasting in the quadriceps and hip flexor muscles. The patient demonstrates minimal sensory loss in the lower limbs. Reflex testing reveals an absent knee-jerk reflex, while the ankle jerks are preserved.

A) Peripheral neuropathy
B) Diabetic lumbosacral radiculopathy
C) Lumbar spinal stenosis
D) Myopathy
B) Diabetic lumbosacral radiculopathy

………………..Fracture in pars interarticularis
Spondylolysis ( pars defect )
……………….Displacement of one vertebra on another
Spondylolisthesis
People who have Spondylosis are at risk for
Disc herniation
In intervertebral disk degeneration the disc herniate ………. and in facet joints degeneration the disc herniate …………

Patient Case Scenario:
A 45-year-old woman presents to the clinic with complaints of unilateral lower back pain that has been persistent for the past two weeks.
