Hip abductor defect repair by means of a vastus lateralis muscle shift

Scarring or detachment of the hip abductors, particularly of the gluteus medius, from their insertion may lead to severe abductor weakness, recurrent dislocations, pain, and diminished quality of life. We performed a retrospective study to evaluate whether vastus lateralis shift is associated with satisfactory results and low rate of complications. Eleven adults underwent vastus lateralis shift to bridge a well-documented abductor muscles' insertion defect. Preoperative and postoperative hip functions were assessed applying the Merle d'Aubigne score, British Medical Council scale, and Visual Analog Scale. Significant postoperative improvement was noted in mean Merle d'Aubigne score, gluteus medius muscle force, and quality of life. Vastus lateralis shift represents a viable treatment option for hip abductor deficiency, significantly improving abductor strength and overall quality of life.

Decompressive hemicraniectomy in patients with supratentorial intracerebral hemorrhage

Decompressive craniectomy (DC) lowers intracranial pressure and improves outcome in patients with malignant middle cerebral artery stroke. Its usefulness in intracerebral hemorrhage (ICH) is unclear. The aim of this study was to analyze feasibility and safety of DC without clot evacuation in ICH.

Do Central Hypersensitivity and Altered Pain Modulation Predict the Course of Chronic Low Back and Neck Pain?

OBJECTIVES:: Widespread central hypersensitivity and altered conditioned pain modulation (CPM) have been documented in chronic pain conditions. Information on their prognostic values is limited. This study tested the hypothesis that widespread central hypersensitivity (WCH) and altered CPM, assessed during the chronic phase of low back and neck pain, predict poor outcome. METHODS:: A total of 169 consecutive patients with chronic low back or neck pain, referred to the pain clinic during 1 year, were analyzed. Pressure pain tolerance threshold at the second toe and tolerance time during cold pressor test at the hand assessed WCH. CPM was measured by the change in pressure pain tolerance threshold (test stimulus) after cold pressor test (conditioning stimulus). A structured telephone interview was performed 12 to 15 months after testing to record outcome parameters. Linear regression models were used, with average and maximum pain intensity of the last 24 hours at follow-up as endpoints. Multivariable analyses included sex, age, catastrophizing scale, Beck Depression Inventory, pain duration, intake of opioids, and type of pain syndrome. RESULTS:: Statistically significant reductions from baseline to follow-up were observed in pain intensity (P<0.001). No evidence for an association between the measures of WCH or CPM and intensity of chronic pain at follow-up was found. DISCUSSION:: A major predictive value of the measures that we used is unlikely. Future studies adopting other assessment modalities and possibly standardized treatments are needed to further elucidate the prognostic value of WCH and altered CPM in chronic pain.
