Randomized Controlled Trial
Pulsed radiofrequency for chronic inguinal neuralgia.
Chronic inguinal neuralgia has been reported after inguinal herniorrhaphy, caesarean section, appendectomy, and trauma to the lower quadrant of the abdomen or inguinal region. ⋯ For intractable chronic inguinal pain, PRF for the dorsal root ganglion represents a promising treatment modality.

Randomized Controlled Trial Comparative Study
Piriformis syndrome: comparison of the effectiveness of local anesthetic and corticosteroid injections: a double-blinded, randomized controlled study.
Piriformis syndrome (PS), which is characterized by pain radiating to the gluteal region and posterior leg, is accepted as one of the causes of sciatalgia. Although the importance of local piriformis muscle injections whenever PS is clinically suspected has been shown in many studies, there are not enough studies considering the clinical efficacy of these injections. ⋯ LA injections for the PS were found to be clinically effective. However, addition of CS to LA did not give an additional benefit. This gives us the idea that PS is mostly muscular in origin and responds well to both LA and LA+CS injections.

Cervicogenic headache is a secondary headache that has a source in the upper cervical spine. There is a small but growing body of evidence to establish effectiveness of radiofrequency (RF) neurotomy, and the pulsed RF (PRF) procedure for management of cervicogenic headache. ⋯ There is limited evidence to support RF ablation for management of CHA as there are no high quality RCTs and/ or multiple consistent non-RCTs without methodological flaws. There is poor evidence to support PRF for CHA as there are no high quality RCTs or Non-RCTs.

Randomized Controlled Trial Comparative Study
Comparison of high-viscosity cement vertebroplasty and balloon kyphoplasty for the treatment of osteoporotic vertebral compression fractures.
Percutaneous vertebroplasty is a widely used vertebral augmentation procedure for treating osteoporotic vertebral compression fractures (OVCFs). But high cement leakage rate caused by a low-viscosity cement and high injection pressure has limited its general use. Balloon kyphoplasty (BKP) and high-viscosity cement vertebroplasty (HVCV) are 2 modifications of vertebroplasty designed to decrease cement leakage. ⋯ HVCV and BKP are safe and effective in improving quality of life and relieving pain. HVCV has a lower cement leakage rate, whereas BKP is more effective in vertebral height restoration. Subsequent fractures are not different between the 2 groups.

Randomized Controlled Trial
Perioperative lidocaine infusion reduces the incidence of post-mastectomy chronic pain: a double-blind, placebo-controlled randomized trial.
Chronic post-surgical pain (CPSP) is a not uncommon complication after mastectomy, with a reported incidence between 20% and 68%. Careful dissection, the use of minimally invasive surgical techniques, and attempts to reduce the associated inflammatory and hyperalgesic responses are suggested methods to prevent CPSP. ⋯ Perioperative lidocaine administration was associated with a decreased incidence of CPSP, while breast implant placement and radiotherapy were associated with an increased incidence. These findings suggest a protective effect of lidocaine on CPSP development in mastectomy patients.
