In the 1990s, radiofrequency ablation emerged as a novel therapeutic approach tool for pain alleviation that did not result in neurological harm. Radiofrequency techniques are emerging methods as a possible option for upper extremity pain management. Furthermore, joint pain can result from multiple etiologies, and the management can differ based on what joint is affected. With the various management methods available to treat joint pain, radiofrequency ablation could be an effective, minimally invasive, promising intervention. ⋯ Radiofrequency techniques are a promising, minimally invasive procedure for controlling upper extremity pain. More studies on the topic, especially on elbow and wrist pain, are warranted for the generalizability of the results.

Epidural injection (EI) has been used to manage lower back and radicular leg pain caused by a herniated lumbar disc. There are 3 types of EI techniques currently being used: transforaminal (TFEI), interlaminar (ILEI), and caudal epidural injections (CEI). ⋯ TFEI had the best potential of the 3 EI techniques to reduce pain and improve function in patients with a herniated lumbar disc. Further qualified trials comparing the effects of these 3 techniques are warranted to derive definitive conclusions.

Treatment of intermediate-stage painful degenerative disc disease is controversial, with few reliable options. Allogenic mesenchymal stem cells (MSCs)are an alternative to autologous stem cell transplantation. Allogeneic MSCs in the treatment of discogenic low back pain have some practical advantages, ranging from availability to ease of treatment in a procedure-room setting. ⋯ The results of our feasibility study suggest that the injection of allogeneic MSCs to treat patients with painful intermediate-stage degenerative disc disease has merit. No adverse reactions were observed. The authors recommend further study in a randomized prospective study setting with a placebo control group or a natural history study group of patients to solidify this research.

Postoperative pain is a concern after thoracic and breast surgeries. Recent studies have demonstrated that ultrasound-guided serratus anterior plane block (SAPB) could provide postoperative analgesia. ⋯ Our findings suggest that SAPB not only relieves acute pain after thoracic and breast surgery, but also reduces the incidence of chronic postsurgical pain.

Although poorly studied, chronic postsurgical neuropathic pain (CPNP) represents the second most frequent chronic neuropathic pain etiology, probably affecting 0.5% to 75% of patients with a severe impact on quality of life (QoL). No consensus or treatment algorithm has been elaborated to date, despite a large variety of approaches now available. Transversus abdominis plane (TAP) block has been endorsed as an efficient treatment for acute postoperative pain although its effect on CPNP in terms of intensity and QoL has yet to be considered. ⋯ The TAP block is easy to learn, easy to reproduce, and easy to administer. After pooling our results with those from the literature, a TAP block is deemed to be effective for the treatment of CPNP with 82.25% effectiveness over a mean time of 13.9 weeks. A TAP block improves long-term QoL, reduces consumption of painkillers and lowers pain scale scores. Thus, it may reduce health care costs. We argue that A TAP block should be considered early, from the onset of the first pain symptoms.
