Short-term link between percutaneous treatments for acetabular breaks: practical outcomes, radiographic evaluation and also problems.
Average (SD) NRS-11 was 4.2 (2.6). Significant impact of LBP on sleep (24%), depression/psychological problems (24%), and social life (28%) were observed. Women (OR, 2.23; 95% CI, 1.80-2.77; P < 0.05), walking/lifting activity (OR, 1.362; 95% CI, 1.097-1.692; P < 0.05), and increasing age (OR, 1.03; 95% CI, 1.02-1.04; P < 0.05) were most significant positive predictors of LBP.

The progression of LBP could not be assessed in the enrolled patients.

LBP is highly prevalent in India, adversely affecting QOL in respondents. This calls for action by health officials to plan prevention, education, and management programs in the society.

Intraspinal cement leakage is a catastrophic complication of percutaneous vertebroplasty (PVP). Percutaneous endoscopic spinal surgery (PESS) for intraspinal cement leakage has rarely been reported.

To evaluate the therapeutic effectiveness of PESS for intraspinal cement leakage following PVP.

This was a retrospective study approved by the ethics committee of our institution.

Department of Orthopedics from an affiliated hospital.

Twelve patients with neurologic impairments resulting from intraspinal cement leakage after PVP were treated with PESS for spinal decompression from May 2014 to June 2018. Computed tomography and 3-dimensional reconstruction were used to confirm the vertebral level of cement leakage. The surgical index, neurologic function, and clinical results were recorded in this study.

The leaked cement of all patients was successfully removed under PESS, and no severe intraoperative complications were reported in our study. The operation time ranged from 43 to 119 minutes (mean, 65.5minimally invasive surgery, percutaneous vertebroplasty.
Surgical options for thoracic pain are limited and carry significant risk and morbidity. Spinal cord stimulation has the potential to be used for treatment of thoracic pain, as it has been useful for treating multiple types of chronic pain. Conventional tonic stimulation is limited in the treatment of thoracic pain, as it can produce paresthesia that is difficult to localize. Conversely, high-frequency spinal cord stimulation (HF-SCS) does not activate dorsal column A Beta fibers and does not produce paresthesia, and thus may be more beneficial in treating thoracic back pain not manageable with tonic stimulation.

To evaluate (1) the efficacy of 10 kHz HF-SCS for patients with chronic thoracic pain; and (2) appropriate paresthesia-free lead placement and programming targets for 10 kHz HF-SCS for patients with chronic thoracic pain.

Retrospective case series.

Multisite academic medical center or pain clinic.

A retrospective chart review was performed on 19 patients with thoracic back pain who underwenertebrae were used for stimulation.

This study is limited by its retrospective design. Additionally, including documentation from multiple sites may be prone to selection and abstraction bias. Data were also not available for all patients at all time points.

HF-SCS may be a viable option for significant, long-lasting pain relief for thoracic back pain. There may also be evidence for anatomically based lead placement and programming for thoracic back pain. Randomized, controlled trials with extended follow-up are needed to further evaluate this therapy.

Ultrasound-guided perineural injections at the lateral femoral cutaneous nerve (LFCN) may confirm the correct diagnosis and provide symptom relief in meralgia paresthetica. Although correct visualization of the nerve is generally described as feasible, failure rates of the procedure may be as high as 30%.

This study investigated the spread of injected fluids in ultrasound-guided perineural injections at the LFCN. The aim of the study was to evaluate whether the inguinal ligament impedes the distribution of injected fluids along the course of the LFCN.

We used a descriptive research design.

Research was conducted at an anatomical research facility.

In fresh, nonembalmed cadavers, 2 mL of ink were injected with ultrasound-guidance at the LFCN below the inguinal ligament. The course of the nerve was then dissected to show the extent of nerve staining.

Spread of the injected ink proximal to the inguinal ligament was found in 67.65% of specimens, while the ink did not pass the inguinal ligament in 32.35%. Concerning proximal spread, specimen body mass index was not of any relevance.

This cadaver study is only a simulation of the real clinical setting and does not allow any insight into the efficacy of the injection in living patients.

The inguinal ligament is a barrier in the distribution of injected fluids in about one-third of specimens. This might be a major cause of failure in ultrasound-guided injections. The results from our study are in line with previously published failure rates and our findings might provide the anatomic basis to advance injection techniques.

Fibromyalgia (FM) syndrome is characterized by widespread pain, fatigue, and generalized increased pain sensitivity. Appropriate and simple pain models are methods employed to assess pain mechanisms that can potentially lead to improved treatments. Selleckchem AZD1080 Pressure pain thresholds (PPTs) or mapping the referred pain area produced by pressure stimulation at suprathreshold intensities are used to assess pain mechanisms. The optimal suprathreshold stimulation intensity to elicit referred pain with minimal discomfort for patients with FM has yet to be determined.

The aim of this study was to compare the area and intensity of pressure-induced referred pain in patients with FM as elicited by systematic increases in PPTs, compared with controls.

Observational, crossed-section study.

Research laboratory.

Twenty-six patients with FM and 26 healthy controls, age- and gender-matched, were included. Suprathreshold stimulation was applied to the infraspinatus muscle of the dominant side at 4 different intensities (PPT +20%, +30%, +40%, and +50%), after which referred pain was evaluated by measuring the area of pain in pixels using a digital body chart and its intensity on a Visual Analog Scale.
