Variability in Management Practices and Surgical Decision Making in Spinal Tuberculosis: An Expert Survey-Based Study

Methods@#Seventeen fellowship-trained spinal TB experts representing different geographical regions of India completed an online survey consisting of questions pertaining to the conservative management of spinal TB (antitubercular therapy) and 30 clinical case vignettes including a wide spectrum of presentations of spinal TB with no or minimal neurological deficit. The variability in the responses for questions and case wise variability with respect to surgical decision making was assessed using the index of qualitative variation (IQV). The average tendency to operate (TTO) was calculated for various groups of respondents. @*Results@#High variability was observed in all questions regarding conservative spinal TB management (IQV > 0.8). Among the 30 case vignettes, 14 were found to have high variability with respect to surgical decision making (IQV > 0.8). With respect to levels of fixation, all but two cases had poor or slight agreement. Younger age and practice in a government or tertiary care teaching hospital were factors associated with a higher TTO. @*Conclusions@#Significant variability was detected in treatment practices for the management of spinal TB among experts. Most of the case vignettes were found to have significant heterogeneity with respect to surgical decision making, which reflects a significant lack of consensus and lacunae in literature.

Assessment of Acetabular Component Anteversion after Total Hip Arthroplasty: Comparison of Anteroposterior and Cross-Table Lateral Radiographs with Computed Tomography Scans

Background@#Several methods of measurement of anteversion of acetabular components after total hip arthroplasty (THA) have been described in the literature using plain radiographs or computed tomography (CT) scans. None of these have proved to be the gold standard. We aimed to study the correlation between the CT and radiographic methods of calculation of acetabulum anteversion. @*Methods@#CT scans of the pelvis, anteroposterior (AP) and cross-table lateral (CL) radiographs were obtained in 60 patients who underwent THA two weeks after surgery. Anteversion was measured using Widmer method and Liaw method on AP radiographs, and the ischiolateral method on CL radiographs. Anteversion measured on the CT scan was taken as the reference anteversion and the above measurements were analysed for correlation with the measurements on CT scan. Intraclass correlation coefficients (ICCs) were calculated for both intra- and interobserver reliability. @*Results@#Mean acetabular version on CL radiographs was 53.1 ± 10.7. Mean version on AP radiographs by Widmer method was 21.4 ± 3.6 and by Liaw method was 20.3 ± 4.8. Mean version on CT scans was 26.02 ± 6.8. There was a good correlation between the acetabular version on CT scans with the version on AP radiographs by Widmer method (r = 0.78, p < 0.001) and Liaw method (r = 0.87, p < 0.001). Good correlation was seen between the acetabular version on CL radiographs and CT scans (r = 0.91, p < 0.001). Also, a good correlation was observed between the acetabular version measurements on CL radiographs and AP radiographs by Widmer method (r = 0.81, p < 0.001) or Liaw method (r = 0.70, p < 0.001). Excellent inter- and intraobserver reliability were seen for all the measurements. @*Conclusions@#Calculation of acetabular component version on AP views as well as CL views of plain radiographs showed a strong correlation with the version measurements on CT scans. Good correlations were observed between different techniques of measurement on radiographs. Therefore, all these measurements can be valid methods for assessment of anteversion.

Hip Arthroscopy for Sequelae of Legg-Calve-Perthes Disease: A Systematic Review / 대한고관절학회지

There is no clear evidence on indications and outcomes of hip arthroscopy in sequelae of Legg-Calve-Perthes disease (LCPD). The aim of the current study was to evaluate current literature on the role and outcome of hip arthroscopy in LCPD. A literature search using four databases was conducted in April 2020, focusing on the role of hip arthroscopy in sequelae of LCPD. A systematic search was carried out in confirmation with the Cochrane Collaboration, Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of nine studies were included in the systematic review. The total number of hip arthroscopies performed for LCPD was 109. The mean age of included patients was 34.8±7.88 years (7-58 years). Recalcitrant hip pain was the main indication for surgery, followed by pain and stiffness. The most common finding in arthroscopy was labral tears, followed by osteochondral lesions of femoral head or acetabulum and intra-articular loose bodies. Consequently, debridement of labrum tears chondroplasty for cartilage defects and osteoplasty for impingement from deformed femoral head (hinged abduction) were commonly performed. A significant improvement in hip function was seen in all studies. Pooled data of Harris hip score showed significant improvement after surgery was conducted.Hip arthroscopy may be beneficial in patients having symptoms of impingement secondary to changes in labrum, femoral head or acetabulum. Limited evidence shows improved function and range of motion after surgery. This treatment has been found to be safe in terms of complication rates and improvement may persist for years.

Local infiltration analgesia following total hip replacement: a review of current literature / 中华创伤杂志(英文版)

Controlling postoperative pain after total hip replacement is important and controversy remains regarding different regimens. By reviewing 18 studies, we attempt to find whether local infiltration analgesia after total hip replacement has any effect on postoperative pain, length of hospital stay and opioid consumption. We conclude that local infiltration analgesia is an effective method for decreasing postoperative pain.

Evaluation of interadductor approach in neurolytic blockade of obturator nerve in spastic patients

Spasticity is a syndrome associated with a persistent increase in involuntary reflex activity of a muscle in response to stretch. Adductor muscle spasticity is a common complication of spinal cord and brain injury. It needs to be treated if it interferes with activities of daily living and self-care. Obturator neurolytic blockade is one of the cost-effective therapeutic possibilities to treat spasticity of adductor group of muscles. In this study, we assessed the efficacy of interadductor approach in alleviating the spasticity. Obturator neurolysis using 8-10 ml 6% phenol was given with the guidance of a peripheral nerve stimulator in 20 spastic patients. Technical evaluation included number of attempted needle insertions, time to accurate location of the nerve, depth of needle insertion, and success rate. Pain, spasticity, hip abduction range of motion [ROM], number of spasms, gait, and hygiene were evaluated at 1[st] hour, 24[th] hour, end of the 1[st] week, and in the 1[st], 2[nd], and 3[rd] months following the intervention. The success rate was 100% with mean time to accurate nerve location 4.9 +/- 2.06 min. Average depth of needle insertion was 2.91 +/- 0.32 cm. Compared with the scores measured immediately before the block, all studied parameters improved significantly. An increase in the Modified Ashworth Scale values was observed in the 2[nd] and 3[rd] months, but they did not reach their initial values. The interadductor approach proved to be accurate and fast, with a high success rate. Phenol blockade is an efficient and cost-effective technique in patients with adductor spasticity. It led to a decrease in spasticity and pain with an increase in the ROM of the hip and better hygiene, with an efficacy lasting for about 3 months

Spasticity - pathogenesis, prevention and treatment strategies

This review of the long-term management of spasticity addresses some of the clinical dilemmas in the management of patients with chronic disability. It is important for clinicians to have clear objectives in patient treatment and the available treatment strategies. The review reiterates the role of physical treatment in the management, and thereafter the maintenance of patients with spasticity. Spasticity is a physiological consequence of an injury to the nervous system. It is a complex problem which can cause profound disability, alone or in combination with the other features of an upper motor neuron syndrome, and can give rise to significant difficulties in the process of rehabilitation. This can be associated with profound restriction to activity and participation due to pain, weakness, and contractures. Optimum management is dependent on an understanding of its underlying physiology, an awareness of its natural history, an appreciation of the impact on the patient, and a comprehensive approach to minimizing that impact. The aim of this article is to highlight the importance, basic approach, and management options available to the general practitioner in such a complex condition
