43-year-old male suffered of cervical disc herniation, and therefore C5-6 and C6-7 discectomy and fusion were done. About one year later he experienced acute sciatica followed by hot pricking sensation in the arm and neck. MRI showed far lateral bulge of L3-4 on the left and small disc bulge on C4-5, and a larger C5-6 disc herniation. Neurological examination disclosed C6-C7 radiculopathy on the left, minimal weakness of biceps and triceps muscles and reduced biceps reflex. EMG and physical examination were consistent with bilateral radiculopathy, attributed to small disc herniation.

Male patient had twist injury of his knee with tear of the ACL and was operated. After the surgery he suffered acute lumbalgia. Twelve days later he was re-admitted for knee effusion and elevated body temperature, and arthrolysis and joint washing were performed. Following the procedure he complained of hypoesthesia of the proximal lower left limb and knee. EMG reveled L4 and S1 root damage, and MRI showed reduced lumbar lordosis and different disc lesions. In case of compression neuropathy (tourniquet), the expert recommends symptomatic only treatment.
