In all levels of disc herniations the absolute surgical indications include deteriorating neurological deficits with myelopathy or cauda equina syndrome. However, this review summarized the relative indications for surgery in each level. In cervical disc herniation (CDH), the indications for surgery consist of six months of persisting symptoms, not responding to conservative treatment. However, high-quality studies are lacking, and a randomized controlled trial is now underway to clarify the indications. In thoracic disc herniation (TDH), the indications for surgery comprise failure of conservative measures and/or worsening neurological symptoms. Moreover, giant calcified thoracic disc herniations or myelopathy signs on magnetic resonance imaging, even in the absence of neurological symptoms, may benefit from surgical treatment as a preventive measure. In lumbar disc herniation (LDH), the indications for surgery include imaging confirmation of LDH, consistent with clinical findings, and failure to improve after six weeks of conservative care.

Study designA systematic review reporting on the efficacy of an ERAS protocol in patients undergoing spinal fusion for AIS.ObjectiveTo systematically evaluate the relevant literature pertaining to the efficacy of ERAS protocols with respect to the length of stay, complication, and readmission rates in patients undergoing posterior spinal corrective surgery for AIS.Summary of background dataERAS is a multidisciplinary approach aimed at improving outcomes of surgery by a specific evidence-based protocol. The rationale of this rapid recovery regimen is to maintain homeostasis so as to reduce the postoperative stress response and pain. No thorough review of available information for its use in AIS has been published.MethodsA systematic review of the English language literature was undertaken using search criteria (postoperative recovery AND adolescent idiopathic scoliosis) using the PRISMA guidelines (Jan 1999-May 2020). Isolated case reports and case series with ResultsOf a total of 24 articles, 10 studies met the inclusion criteria (9 were Level III and 1 of level IV evidence) and were analyzed. Overall, 1040 patients underwent an ERAS-type protocol following posterior correction of scoliosis and were compared to 959 patients following traditional protocols. There was a significant reduction in the length of stay in patients undergoing ERAS when compared to traditional protocols (p p = 0.19) or readmission rates (p = 0.30). Each protocol employed a multidisciplinary approach focusing on optimal pain management, nursing care, and physiotherapy.ConclusionThis systematic review demonstrates advantages with ERAS protocols by significantly reducing the length of stay without increasing the complications or readmission rates as compared to conventional protocols. However, current literature on ERAS in AIS is restricted largely to retrospective studies with non-randomized data, and initial cohort studies lacking formal control groups.Level of evidence3.

PURPOSE: We report a case of a patient with an acute symptomatic Schmorl node (SN) that spontaneously resolved with characteristic imaging findings. The extensive hematological investigations also allow some insight as to the likely pathophysiology of the painful lesion. METHODS: Case report of an acute symptomatic SN. RESULTS: A fit and athletic 44-year-old female participant in a competitive paddling event developed atypical thoracic pain and was admitted for further investigation. Normal blood results included complete blood cell count, clotting, and D-dimer. Creatine phosphokinase was 63 U/L (reference < 167 U/L) and troponin I levels were not raised. Her only hematological abnormality was an elevated C-reactive protein (CRP) at 60.2 mg/L (reference < 5 mg/L). Magnetic resonance imaging (MRI) scan showed signal hyperintensity involving T7 vertebral body, surrounding an enlarged SN. Patient was given oral nonsteroidal anti-inflammatory drugs, opioid analgesia, and gradually mobilized. After 3 days, the pain had sufficiently subsided and CRP was 17.8 mg/L. Follow-up MRI scan showed some reduction in the T2 hyperintensity and size of the intraosseous herniation. Patient gradually returned to full activities and had no recurrence of symptoms. MRI scan 8 months after the initial scan showed almost complete resolution of the T2 hyperintensity and pan-vertebral marrow edema. CONCLUSION: Symptomatic SN should be part of the differential diagnosis of unexplained thoracolumbar pain. Modality of choice for diagnosis would be MRI. Once diagnosed, several treatment options are available with the most likely being spontaneous resolution of symptoms and bone healing within a few months. The conservative approach is recommended when the symptoms can be medically well controlled.

Background MRI is the most accurate imaging modality for diagnosing knee pathologies. However, there is uncertainty concerning factors predicting false negative MRI, such as meniscal tear patterns as well as patient factors. The aims of this study were to report 1.5-Tesla MRI accuracy of ACL, meniscus and articular cartilage damage and characterize false negative lesions. Methods Two hundred eighteen consecutive knee arthroscopies performed in our institution between 2013 and 2016 and their respective prospectively-collected MRI reports were reviewed. Inclusion criteria were age > 15 years-old, primary arthroscopy, 1.5-Tesla MRI performed at the same institution, and time interval MRI-surgery Results The highest accuracy was observed in medial meniscus and in ACL findings. For the medial meniscus sensitivity, specificity, agreement, and Kappa coefficient were 77, 92, 86%, and 0.7, and for the ACL these measures were 82, 97, 87%, and 0.73. MRI accuracy was lower in the lateral meniscus and articular cartilage with Kappa coefficient 0.42 and 0.3, respectively. More specifically, short peripheral tears in the posterior horn of the medial meniscus were characteristic of false negative findings compared to true positive findings of the MRI (p r = − 0.21, p = 0.002) and for articular cartilage damage (r = − 0.45, p Conclusion 1.5-Tesla MRI will accurately diagnose ACL and medial meniscal tears and can reliably complete the diagnostic workup following physical examination, particularly in young adults. This modality however is not reliable for diagnosing short peripheral tears at the posterior horn of the medial meniscus and partial thickness articular cartilage lesion of the femoral condyles. For these lesions, definitive diagnosis may require cartilage-specific MRI sequences or direct arthroscopic evaluation. Level of evidence Prognostic study, Level III.

Most spinal metastases are detected late, and thus, the impact of treatment on the health-related quality of life (HRQOL) is an important consideration. This study investigated the HRQOL following surgery for spinal metastases. A prospective study of patients operated for symptomatic spinal metastases, at a single tertiary referral spine centre (2011–2013). Data were collected pre-operatively and up to 2 years following surgery (if alive). The HRQOL assessment was performed using recognised systems including the Frankel score (neurological status), EQ-5D, and the Oswestry Disability Index. A total of 199 patients were studied (median age 65 years, 43% (86) F; 57% (113) M). The Frankel score improved significantly after surgery in 69 patients (35%), worsened in 17 (8%), with 20/39 patients regaining the ability to walk (51%). All the HRQOL scores improved significantly following surgery. The complication rate was 27% and median survival 270 days, and 44 patients (22%) survived at 2 years. This large prospective study showed that surgical treatment for spinal metastases significantly improved the HRQOL.

Objective To test whether patients with spontaneous osteonecrosis of the knee (SONK) are characterized by abnormal levels of thrombophilia-associated factors. Design Twenty-five patients with SONK were recruited. Inclusion criteria were (1) age >40 years, (2) acute onset knee pain not precipitated by trauma, and (3) MRI findings consistent with SONK. Exclusion criteria were (1) history of cancer and chemotherapy and (2) factors associated with secondary osteonecrosis. Blood tests included 13 thrombophilia-associated factors that were either heritable mutations or acquired factors. Descriptive statistics included medians, ranges, means, and standard deviations. Mann-Whitney test was used to compare thrombophilia-associated factor levels between the sexes. Spearman’s rank test was used to test correlations between smoking status and each thrombophilia-associated factor. Level of significance was set at 0.05. Results Median patient age was 62 years (range, 44-77 years). There were 16 (64%) men. Thirteen (52%) patients had thrombophilia-associated factor abnormalities of which 9 were elevated fibrinogen but this was less than 1 standard deviation above norm threshold. Other findings were 3 patients with marginally decreased antithrombin below norm threshold, low protein S Ag in only 1 patient, and factor V Leiden mutation heterozygosity in 2 patients, which was not higher than normal population prevalence. Thrombophilia-associated factors neither differed between sexes ( P = nonsignificant) nor correlated with smoking status ( P = nonsignificant). Conclusion Thrombophilia-associated factor abnormalities in patients with SONK were minimal. Therefore, clinical workup and treatment strategy in this disease should focus on addressing alternative etiologies leading to abnormal subchondral bone metabolism with focal osteopenia.

Background:There are limited data regarding associated factors of return to sports activities at more than 5 years after anterior cruciate ligament (ACL) reconstruction.Purpose:To test interrelationships between patient characteristics, concomitant articular lesions, graft laxity, and maintenance of sports activities at 5 to 10 years after ACL reconstruction. It was hypothesized that at 5 to 10 years after the operation in young adult men, maintenance of greater activity level and better knee function would be associated with greater preinjury activity level, younger age at reconstruction, absence of concomitant articular lesions, and minimal graft laxity at follow-up.Study Design:Case series; Level of evidence, 4.Methods:One hundred six men with autologous hamstring ACL reconstruction between the ages of 18 and 35 years were reviewed at 5 to 10 years after surgery. Excluded patients had contralateral ACL tear, revision reconstruction, or another injury impairing function. Fifty-five patients were eligible and available for follow-up. Independent variables included preinjury Tegner score, time interval from injury to surgery, smoking status, age, articular lesions, KT side-to-side difference, and pivot-shift grade. Main outcome measures were Tegner activity level, International Knee Documentation Committee (IKDC) subjective score, and Knee injury and Osteoarthritis Outcome Scale (KOOS) score at 5 to 10 years after surgery.Results:Greater Tegner activity level at follow-up was associated in a regression model with greater preinjury Tegner activity level (correlation coefficient, 0.423; P = .01), lower KT difference (correlation coefficient, –0.278; P = .04), and negative pivot shift (correlation coefficient, –0.277; P = .05). Younger age at operation predicted return to greater Tegner activity level in a univariate analysis (correlation coefficient, –0.266; P = .05) but not in a regression model (not significant). Chondral lesions at surgery predicted lower IKDC subjective scores (71.4 ± 14.3 vs 84.1 ± 11.5; P < .01) and KOOS scores but did not affect maintenance of sports activities.Conclusion:At 5 to 10 years after autologous hamstring ACL reconstruction in young men, predictors of greater sports activity level are primarily high preinjury activity level and reestablishment of knee laxity. Younger age at operation and moderate chondral lesions have lower impact in this respect.
