Case Reports Observational Study
The response to radiofrequency neurotomy of medial branches including a bipolar system for thoracic facet joints.
Background and aims The evidence for interventional treatment of thoracic facet joint pain remains limited. This is partly due to inconsistency of the path of thoracic medial branches and a lower incidence of thoracic facet pain among spine pain patients. The purpose of this study is to evaluate the efficacy of bipolar radiofrequency (RF) neurotomy of medial branches for treating chronic thoracic facet joint pain. ⋯ There were no serious adverse effects or complications of the procedure reported in this study. Conclusions Bipolar RF neurotomy of thoracic medial branch is associated with a significant reduction in thoracic facet joint pain. The promising findings from this case series merit further assessment with prospective, randomized controlled trial which will produce a more reliable and accurate finding for its clinical applications.

Background and aims Previous studies have suggested there is an association between preoperative expectations about the outcome and outcomes of total knee and total hip arthroplasty (TKA/THA). However, expectations have been rarely examined on their clinical relevance relative to other well-known predictive factors. Furthermore expectations can be measured on a more generic level (e.g. does one expect their symptoms to improve after surgery) or on a more specific level (e.g. does one expect to be able to squat again after surgery). ⋯ Conclusions In planning of surgical treatment, orthopedic surgeons should take a range of variables into account of which the patient's expectations about outcome of surgery is one. The CEQ expectancy subscale predicted outcomes slightly better as the HSS expectation surveys, but differences in predictive value of the two measurements were too small to prefer between the two. Future studies are advised to replicate these findings and externally validate the models presented.

Randomized Controlled Trial
Adding steroids to lidocaine in a therapeutic injection regimen for patients with abdominal pain due to anterior cutaneous nerve entrapment syndrome (ACNES): a single blinded randomized clinical trial.
Background and aims Anterior cutaneous nerve entrapment syndrome (ACNES) may result in chronic abdominal pain. Therapeutic options include local injection therapy. Data on the efficacy of adding corticosteroids to these injections is lacking. ⋯ Minor side effects included temporary increase of pain, tenderness at injection sites or transient malaise (LA23/68, LC 29/68, p=0.46). Conclusions Adding corticosteroids to a lidocaine does not increase the proportion of ACNES patients with a successful response to injection therapy. Lidocaine alone can provide long term pain relief after one or multiple injections, in approximately 1 of 5 patients.

Background and aims Evaluating the degree to which pain has become chronic beyond mere duration poses several problems. The IASP Pain Taxonomy Axis IV employs intensity and duration combined to nine ordered categories. The Chronic Pain Grade links intensity and disability, but only the latter contributes to higher grades. ⋯ There is evidence for at least three weakly coupled core domains of chronicity, i.e. the primary clinical characteristics, the direct consequences of current interference with activities, and aspects of the patient history. Hence, multivariate assessment is recommended. The particular syndrome, the diagnostic context and the population under investigation should likewise be considered.

Background and aims Chronic pelvic pain (CPP) impacts significantly on the lives of women. Negative coping responses such as pain catastrophizing are thought to be significant in predicting both pain severity and outcome. The combined effect of the individual's response to pain and its severity on their quality of life (QoL) has not been well studied in women with CPP. ⋯ Conclusions Pain catastrophizing is prevalent at clinically relevant levels in women with CPP across all domains. It is associated with higher pain levels and decreased QoL. Implications There is potential for further studies to investigate the predictive nature of pain catastrophizing and management targeting catastrophizing to improve outcomes in women with CPP.
