Proximal tibial neuropathy is an uncommon focal mononeuropathy that is most often caused by trauma, ischemia, or neoplastic infiltration or compression of the tibial nerve. We report a patient who presented with a tibial neuropathy following a leg injury, which initially mimicked a lumbosacral radiculopathy but which was the result of a proximal tibial neuropathy. Electrophysiologic studies confirmed a proximal tibial neuropathy and MRI revealed a popliteus muscle hemorrhage with mass effect on the tibial nerve. Following conservative management the patient had little recovery of function after 15 months.

The acute onset of neck pain and arm weakness is most commonly due to cervical radiculopathy or inflammatory brachial plexopathy. Rarely, extracranial vertebral artery dissection may cause radiculopathy in the absence of brainstem ischemia. We describe a case of vertebral artery dissection presenting as cervical radiculopathy in a previously healthy 43-year-old woman who presented with proximal left arm weakness and neck pain aggravated by movement. Cervical magnetic resonance imaging (MRI) and angiography revealed dissection of the left vertebral artery with an intramural hematoma compressing the left C5 and C6 nerve roots. Antiplatelet treatment was commenced, and full power returned after 2 months. Recognition of vertebral artery dissection on cervical MRI as a possible cause of cervical radiculopathy is important to avoid interventions within the intervertebral foramen such as surgery or nerve root sleeve injection. Treatment with antithrombotic agents is important to prevent secondary ischemic events.

Spinal cord ischemia is a rare but possible neurological complication following routine conservative treatment of lumbosacral radiculopathy. A case of a 46 year old woman with chronic L5 radiculopathy, who developed spinal cord ischemia following epidural steroid injection, is reported. Two months after the epidural injection, she required crutches for walking and had neurogenic bladder and bowel.

Ciprofloxacin is recognized to have a deleterious relationship with tendons, particularly Achilles tendinopathy, which makes up most case reports. Tendinopathy seems to occur because of induction of collagen-degrading enzymes causing damage and ischemia of the poorly vascularized regions preventing repair. The focus on the relationship of ciprofloxacin and the Achilles tendon leaves patients on fluoroquinolones with non-Achilles tendinopathy symptoms at risk of misdiagnosis. There have not been any documented instances of ligament damage with ciprofloxacin administration in the literature, although ligament and tendon compositions are similar and should have similar susceptibility. This report includes two cases, one presenting with right lateral thumb pain and a medical history of gastroenteritis treated with ciprofloxacin. Physical examination showed swelling of the right metacarpophalangeal joint and ultrasound confirmed disruption of the radial collateral ligament at insertion on first metacarpal; the second case is of a woman presenting with right hip pain in setting of chronic recurrent diverticulitis treated with ciprofloxacin. She received work-up for lumbar disc disease and spondylosis. After standard therapy with pharmacotherapy and physical therapy for radiculopathy failed, magnetic resonance imaging was performed showing near complete avulsion of the right hamstring tendons from the ischial tuberosity.

Transforaminal epidural steroid injections are a common intervention in the treatment of radicular pain. Complications are rare, but can be catastrophic. One of the potentially devastating complications is occlusion of the artery of Adamkiewicz (AKA). This report is a description of an approach to avoid the complication of injury to the AKA related to transforaminal epidural injection. A 71-year-old male patient presented at the clinic with radiculopathy secondary to lumbar disc hernia. A transforaminal epidural steroid injection was planned. After a radiocontrast injection, vascular filling was detected. The needle was repositioned and an inferior entrance to the epidural space was used. No vascularity was seen and dexamethasone was administered to the patient. A transforaminal epidural steroid injection is an effective interventional treatment for radicular pain, but it requires careful attention due to the possible complications. The AKA was located in the upper half of the foramen. Keeping the wide variation in the anatomy of the AKA in mind is very important in order to prevent spinal cord ischemia.

Cervical nerve root infiltrations are frequently performed in patients with radiculopathy, and computed tomography (CT) is commonly used for image guidance. With the traditional anterolateral approach, catastrophic side events due to spinal ischemia have been reported. To minimize risk, a dorsal approach has been advised, but the safety of this dorsal approach has not been studied systematically. In a 5-year period, 137 cervical nerve root infiltrations using a dorsal approach were performed on 109 patients and retrospectively reviewed. In our series, no major complications like spinal ischemia, spondylodiscitis, large hematomas with the need for surgery or severe allergic reactions occurred. In conclusion, using a dorsal approach, CT-guided cervical nerve root infiltrations with an extraforaminal needle position seem to be a safe intervention.
