With advances in peripheral nerve stimulation technology, there has been an emergence of new minimally invasive techniques to provide neurostimulation therapies for chronic pain. This technical note describes the utilization of ultrasonography for percutaneous placement of peripheral nerve stimulation leads at the sciatic, femoral, and lateral femoral cutaneous nerves. ⋯ The option of ultrasound-guided percutaneous technique for neurostimulation lead placement allows this treatment modality to be made available to more patients with chronic pain in specific nerve distributions.

Upper limb complex regional pain syndrome is an important cause of chronic pain, and its treatment is challenging. In this pilot case series, we preliminarily evaluated the feasibility, effectiveness, and safety of a new technique for brachial plexus neuromodulation in the treatment of this disease in patients refractory to conservative treatment. ⋯ Our data suggest that this new technique of brachial plexus stimulation may have long-term utility in the treatment of painful upper limb complex regional pain syndrome. New more detailed comprehensive studies should be carried out to confirm our findings in a larger population and to further refine the clinical implementation of this technique.
