Virtual platform to tackle challenges associated with lifelong medical education during the COVID-19 pandemic.

BACKGROUND: During the COVID-19 pandemic, large in-person conferences were mostly cancelled to avoid further disease contagion. Physicians continued to demand changes in form to enable participation in lifelong medical education programs, and the traditional model of in-person conferences needed to be rethought. As such, a regional branch of the national orthopedic association tried to move in-person conferences onto a virtual platform. This study aimed to investigate the effect of transitioning large in-person conferences to a virtual model during the COVID-19 pandemic, especially examining any differences in the attendance of each type of conference. METHODS: In this retrospective observational study, 776 participants in virtual conferences and 575 participants in in-person conferences were analyzed. Institutions were classified based on their location in a central city and two neighboring cities. Affiliated institutions were divided into resident training hospitals, general hospitals, and private clinics. The change in the number and proportion of participants between the virtual conference year and in-person conference year was calculated. RESULTS: The number of virtual conference participants was significantly greater than that of in-person conference participants (P = 0.01). Although the highest number of participants was from central city for both years, the proportion of participants from the two neighboring cities increased. Although the proportion of participants from resident training hospitals and private clinics decreased, the proportion of participants from general hospitals increased. CONCLUSIONS: We implemented a virtual platform to tackle challenges associated with lifelong medical education during the COVID-19 pandemic. The virtual platforms can be helpful for organizations that must hold regular lifelong medical education programs for members spread across a wide geographic region.

Comparison of blood loss between intra-articular microporous polysaccharide hemospheres powder and tranexamic acid following primary total knee arthroplasty.

Total knee arthroplasty (TKA) is associated with substantial blood loss and tranexamic acid (TXA) effectively reduces postoperative bleeding. Although it is known that there is no difference between intravenous or intra-articular (IA) injection, the general interest is directed towards topical hemostatic agents regarding thromboembolic events in high-risk patients. This study aimed to compare the blood conservation effects of IA MPH powder and TXA in patients undergoing primary TKA. We retrospectively analyzed 103 patients who underwent primary TKA between June 2020 and December 2021. MPH powder was applied to the IA space before capsule closure (MPH group, n = 51). TXA (3 g) was injected via the drain after wound closure (TXA group, n = 52). All patients underwent drain clamping for three postoperative hours. The primary outcome was the drain output, and the secondary outcomes were the postoperative hemoglobin (Hb) levels during the hospitalization period and the perioperative blood transfusion rates. An independent Student's t-test was used to determine differences between the two groups. The drain output in the first 24 h after surgery was significantly higher in the MPH group than in the TXA group. The postoperative Hb levels were significantly lower in the MPH group than in the TXA group. In patients with simultaneous bilateral TKA, there was a significant difference in the blood transfusion volumes and the rates between groups. It is considered that IA MPH powder cannot replace IA TXA because of an inferior efficacy in reducing blood loss and maintaining postoperative Hb levels in the early postoperative period after primary TKA. Moreover, in the case of simultaneous bilateral TKA, we do not recommend the use of IA MPH powder because it was notably less effective in the field of transfusion volume and rate.

Musculoskeletal Injuries in Table Tennis during Competition: A Systematic Review.

The study aimed to investigate the incidence of musculoskeletal injuries among table tennis players and identify their associated risk factors. We conducted a literature search in online databases using relevant search terms related to "table tennis" and "injury". To compare the rate of injuries according to player-related variables, we extracted information on sex, level of games, circumstances of injury, and duration of sport absence after injury. Furthermore, we calculated the odds ratios based on the number of injuries according to variables. Eight articles included 873 professional table tennis players, revealing an overall musculoskeletal injury rate of 3.6% (31 musculoskeletal injuries). The incidence was 10.0 injuries per 1,000 playing hours (range, 0-27.0). The rate of musculoskeletal injuries for female and male players were 3.2% and 3.8%, respectively, and those for Summer Olympic Games, Asian Games, and domestic national games was 4.8%, 15.4%, and 0%, respectively. More than half (52%) of injuries occurred during training, and most injuries (64%) were of a nature that did not cause time loss. This review provides valuable information about the incidence of musculoskeletal injuries in table tennis competitions. However, owing to the limitations of this study in identifying injury-related risk factors, future studies analyzing comprehensive variables are required.

Surgery-related anxiety regarding arthroscopic meniscectomy under general anesthesia: a retrospective observational study.

BACKGROUND: The prevalence of anxiety among patients undergoing arthroscopic surgery and its association with postoperative function has been well documented; however, the level of anxiety and anxiety-related characteristics remain unclear. As such, the present study investigated the characteristics of state anxiety in patients undergoing arthroscopic meniscectomy. METHODS: Data from 75 patients, who underwent arthroscopic partial meniscectomy under general anesthesia and completed an anxiety status questionnaire between April 2021 and March 2022, were retrospectively collected and reviewed. The State-Trait Anxiety Inventory (STAI)-X was used to measure state anxiety; a total score ≥ 52 was defined as clinically meaningful state anxiety. STAI score, main cause of preoperative anxiety, most anxious period, and most helpful factors for reducing perioperative anxiety were investigated. Patients were divided into 2 groups according to the main cause of preoperative anxiety; surgery or anesthesia (group I [n = 47]); and postoperative pain or rehabilitation (group II [n = 28]) Characteristics of state-anxiety between the two groups were compared using independent t-tests. RESULTS: The mean STAI score of the total population was 39.1 points (range, 20-60 points). The mean STAI score was significantly higher in group I than in group II (41.9 vs. 34.4 points, respectively; P < 0.001). The proportion of patients with clinically meaningful state anxiety was significantly higher in group I than in group II (23.4% vs. 3.6%, respectively, P = 0.02). Most patients (66.0% in group I and 50.0% in group II) responded that trust in medical staff was the most helpful factor in overcoming preoperative anxiety. In group I, 63.8% reported that the surgeon's explanation was the most helpful factor in reducing postoperative anxiety, whereas in group II, 71.4% reported that the natural course after surgery was the most helpful factor. CONCLUSIONS: Surgeons should be aware that anxiety related to arthroscopic meniscectomy differs according to patient characteristics, and a preoperative explanation of the postoperative process with the surgeon is important for patients who experience preoperative anxiety regarding anesthesia or the surgery itself.

Predictive Variables for Interventional Angiography among Patients with Knee Hemarthrosis.

Studies regarding the variables that could predict the success of conservative treatment for knee hemarthrosis are lacking. This retrospective study evaluated the laboratory variables of patients who had unsatisfactory results from conservative treatment for knee hemarthrosis. Twenty-nine patients conservatively treated for knee hemarthrosis were included and divided into two groups: group A comprised 14 patients who underwent interventional angiography and selective embolization due to failed conservative treatment, and group B comprised 15 patients with successful results after conservative treatment. The results of the serological and synovial fluid tests were evaluated. The mean number of synovial red blood cells (RBCs) was 1,905,857 cells/µL and 7730 cells/µL in groups A and B, respectively (p = 0.01), while the mean number of RBCs per high-power field (HPF) was 68.9 and 3.2, respectively (p < 0.01). Patients who underwent interventional angiography and selective embolization after failed conservative treatment for knee hemarthrosis had higher synovial RBC counts and RBC counts per HPF than those with successful outcomes after conservative treatment. It is necessary to carefully interpret the results of the synovial fluid analysis in patients with knee hemarthrosis; if the synovial fluid analysis shows a synovial RBC count greater than 81,500 and RBC count per HPF greater than 16.3, we recommend immediate interventional angiography rather than continuing conservative treatment.

Open-Door Laminoplasty Using Lateral Mass Anchoring Screws and Nonabsorbable Sutures in Patients with Multilevel Cervical Myelopathy.

BACKGROUD: The purpose of this study was to evaluate the clinical usefulness of open-door laminoplasty using lateral mass anchoring screws and nonabsorbable sutures (ODLLM) for multilevel cervical myelopathy. METHODS: We retrospectively studied 30 patients who underwent ODLLM. Clinical evaluations were performed using a visual analog scale (VAS), Japanese Orthopaedic Association (JOA) score, and Neck Disability Index (NDI) preoperatively, at 1 year postoperatively, and at the last follow-up. Radiographic evaluation was done using cervical spine radiographs to measure changes in the lordotic angle and range of motion (ROM) preoperatively, at 1 year postoperatively, and at the last follow-up and computed tomography at 1 year postoperatively to measure the opening angle and anteroposterior diameter of the spinal canal. RESULTS: Significant improvement in VAS, JOA, and NDI was seen overall at 1 year after operation. However, there was no significant difference between 1 year after operation and the last follow-up. There were no significant changes in the lordotic angle and neck ROM. The mean opening angle of the opened lamina was measured as 39.04°. The mean anteroposterior diameter was significantly increased from 7.51 ± 1.79 mm before surgery to 13.98 ± 1.80 mm at 1 year of operation. Complications such as laminar reclosure and screw loosening were not observed in all cases. CONCLUSIONS: The ODLLM was technically easy to perform and showed good results comparable to those of conventional techniques. It can be suggested that ODLLM is an appropriate treatment option for multilevel cervical myelopathy.

Autogenous Bone Grafts versue Metal Cage with Allogenic Bone Grafts for Post-Corpectomy Anterior Column Reconstruction in Patients with Infectious Spondylitis.

OBJECTIVE: To evaluate and compare the clinical and radiographic features of 25 patients with infectious spondylitis treated with anterior debridement and reconstruction using autogenous bone grafts vs. a metal cage with allogenic bone grafts. METHODS: The study analyzed 25 patients diagnosed with infectious thoracolumbar spondylitis who underwent anterior radical debridement and reconstruction. Autogenous bone grafts were used in 13 patients (group 1), and a metal cage with allogenic bone grafts was used in 12 patients (group 2). Clinical outcomes were assessed by the visual analogue scale (VAS) scores and neurological status. Additionally, the serological results and the radiographic results using the sagittal Cobb angle were compared. Fusion was evaluated by computed tomography (CT) imaging at 24 months postoperatively. RESULTS: Both groups showed a significant decrease in the postoperative mean VAS scores; however, only, group 1 patients showed a significantly higher VAS score than group 2 patients, 1 month postoperatively (p=0.002). The postoperative neurological status significantly improved. Elevated C-reactive protein levels and erythrocyte sedimentation rate values returned to normal limits at the 2-year follow-up without recurrent infection. No significant intergroup difference was observed in Cobb angle. Bony fusion was confirmed in all patients at CT 24 months postoperatively. CONCLUSION: Although the use of a metal cage with allogenic bone grafts for anterior column reconstruction remains controversial, our results suggest that it can be considered as an effective treatment of option for anterior column reconstruction in patients with infectious spondylitis.

Outcomes of Non-Operative Management for Pseudarthrosis after Pedicle Subtraction Osteotomies at Minimum 5 Years Follow-Up.

OBJECTIVE: Minimal data exist regarding non-operative management of suspected pseudarthrosis after pedicle subtraction osteotomy (PSO). This study reports radiographic and clinical outcomes of non-operative management for post-PSO pseudarthrosis at a minimum 5 years post-detection. METHODS: Nineteen consecutive patients with implant breakage indicating probable pseudarthrosis after PSO surgery (13 women/ six men; mean age at surgery, 58 years) without severe pain and disability were treated with non-operative management (mean follow-up, 5.8 years; range, 5-10 years). Non-operative management included medication, intermittent brace wearing and avoidance of excessive back strain. Radiographic and clinical outcomes analysis was performed. RESULTS: Sagittal vertical axis (SVA), proximal junctional angle, thoracic kyphosis achieved by a PSO were maintained after detection of pseudarthrosis through ultimate follow-up. Lumbar lordosis and PSO angle decreased at final follow-up. There was no significant change in Oswestry Disability Index (ODI) scores and Scoliosis Research Society (SRS) total score, or subscales of pain, self-image, function, satisfaction and mental health between detection of pseudarthrosis and ultimate follow-up. SVA greater than 11 cm showed poorer ODI and SRS total score, as well as the pain, self-image, and function subscales (p<0.05). CONCLUSION: Non-operative management of implant failure of probable pseudarthrosis after PSO offers acceptable outcomes even at 5 years after detection of implant breakage, provided SVA is maintained. As SVA increased, outcome scores decreased in this patient population.

Minimally Invasive Plate Osteosynthesis Using a Screw Compression Method for Treatment of Humeral Shaft Fractures.

BACKGROUND: This study aims to compare the surgical outcomes of open reduction and internal fixation (ORIF) and minimally invasive plate osteosynthesis (MIPO) using a screw compression method in simple humeral shaft fractures. METHODS: This retrospective study was performed with 50 patients who had surgical interventions for the treatment of simple humeral shaft fractures and had follow-ups of at least 12 months in Ulsan University Hospital between August 2008 and June 2015. Group 1 included 23 patients treated with ORIF and group 2 included 27 patients treated with the MIPO technique using a locking screw plate. The time to clinical/radiographic union, the joint range of motion (ROM), and function were evaluated. RESULTS: The average time to clinical/radiographic bone union was shorter in group 2 (12.0 ± 3.7 weeks/14.8 ± 2.0 weeks in group 1 and 9.4 ± 1.3 weeks/12.0 ± 3.3 weeks in group 2; p = 0.022/p = 0.034). Shoulder and elbow joint function evaluated by joint ROM and visual analogue scale (VAS), Korean Shoulder Elbow Society (KSS), American Shoulder and Elbow Surgeons (ASES), and the University of California at Los Angeles (UCLA) scores was excellent in both groups. On the average shoulder ROM at 12 months after the operation, group 1 had forward elevation of 160°, external rotation of 30° in adduction and lumbar vertebra 10 level in internal rotation and group 2 had forward elevation of 170°, external rotation of 35° in adduction and lumbar vertebra 9 level in internal rotation. The mean VAS, KSS, ASES, and UCLA scores were 2.8, 87.0 ± 0.9, 89.4 ± 0.9, and 31.0 ± 1.4, respectively, in group 1 and 1.7, 89.1 ± 2.7, 91.0 ± 1.6, and 32.4 ± 3.2, respectively, in group 2. There were statistically significant intergroup differences in VAS score (p = 0.011). There were significantly less postoperative infections in group 2 (three cases, 10.7% in group 1 and 0 case in group 2; p = 0.041) although all of them were superficial infections and well-treated by an average 4-week course of antibiotics (range, 2 to 6 weeks). CONCLUSIONS: MIPO using a screw compression method in simple humeral shaft fractures demonstrated superior efficacy to ORIF in terms of the time to clinical/radiographic union, pain score, and postoperative infection rate.

Comparison of Arthroscopically Guided Suprascapular Nerve Block and Blinded Axillary Nerve Block vs. Blinded Suprascapular Nerve Block in Arthroscopic Rotator Cuff Repair: A Randomized Controlled Trial.

BACKGROUND: The purpose of this study was to compare the results of arthroscopically guided suprascapular nerve block (SSNB) and blinded axillary nerve block with those of blinded SSNB in terms of postoperative pain and satisfaction within the first 48 hours after arthroscopic rotator cuff repair. METHODS: Forty patients who underwent arthroscopic rotator cuff repair for medium-sized full thickness rotator cuff tears were included in this study. Among them, 20 patients were randomly assigned to group 1 and preemptively underwent blinded SSNB and axillary nerve block of 10 mL 0.25% ropivacaine and received arthroscopically guided SSNB with 10 mL of 0.25% ropivacaine. The other 20 patients were assigned to group 2 and received blinded SSNB with 10 mL of 0.25% ropivacaine. Visual analog scale (VAS) score for pain and patient satisfaction score were assessed 4, 8, 12, 24, 36, and 48 hours postoperatively. RESULTS: The mean VAS score for pain was significantly lower 4, 8, 12, 24, 36, and 48 hours postoperatively in group 1 (group 1 vs. group 2; 5.2 vs. 7.4, 4.1 vs. 6.1, 3.0 vs. 5.1, 2.1 vs. 4.2, 0.9 vs. 3.9, and 1.3 vs. 3.3, respectively). The mean patient satisfaction score was significantly higher at postoperative 4, 8, 12, 24, 36, and 48 hours in group 1 (group 1 vs. group 2; 6.7 vs. 3.9, 7.4 vs. 5.1, 8.8 vs. 5.9, 9.2 vs. 6.7, 9.5 vs. 6.9, and 9.0 vs. 7.2, respectively). CONCLUSIONS: Arthroscopically guided SSNB and blinded axillary nerve block in arthroscopic rotator cuff repair for medium-sized rotator cuff tears provided more improvement in VAS for pain and greater patient satisfaction in the first 48 postoperative hours than blinded SSNB.

The recovery of damaged paraspinal muscles by posterior surgical treatment for patients with lumbar degenerative diseases and its clinical consequence.

BACKGROUND: Posterior lumbar surgery can lead to damage on paraspinal muscles. OBJECTIVE: Our study aimed to examine the recovery in the denervated paraspinal muscles by posterior lumbar surgery and to determine that of improvement in the lower back pain (LBP). METHODS: Depending on surgical treatments, the patients were divided into two groups: The group I (interspinous implantation with decompression) and II (posterior lumbar interbody fusion with decompression). The paraspinal mapping score was recorded for individual muscle. RESULTS: In the group I, there was reinnervation in the denervated multifidus and erector spinae at the upper, surgical and lower levels at 12 months. In the group II, there was reinnervation in the denervated erector spinae at the upper, surgical and lower levels at 12 months. There was significant aggravation in the LBP in both groups at immediate postoperative. But there was significant improvement in it at 6 months in the group I and at 12 months in the group II. CONCLUSION: There was reinnervation in not only denervated multifidus and erector spinae at 12 months following interspinous ligament stabilization but also in denervated erector spinae at 12 months following pedicle screw fixation with fusion.

The Influence of Arthroscopic Remplissage for Engaging Hill-Sachs Lesions Combined with Bankart Repair on Redislocation and Shoulder Function Compared with Bankart Repair Alone.

BACKGROUND: Recurrence of glenohumeral dislocation after arthroscopic Bankart repair can be associated with a large osseous defect in the posterosuperior part of the humeral head. Our hypothesis is that remplissage is more effective to prevent recurrence of glenohumeral instability without a severe motion deficit. METHODS: Engaging Hill-Sachs lesions were observed in 48 of 737 patients (6.5%). Twenty-four patients underwent arthroscopic Bankart repair combined with remplissage (group I) and the other 24 patients underwent arthroscopic Bankart repair alone (group II). Clinical outcomes were prospectively evaluated by assessing the range of motion. Complications, recurrence rates, and functional results were assessed utilizing the American Shoulder and Elbow Surgeons (ASES) score, Rowe score, and the Korean Shoulder Score for Instability (KSSI) score. Capsulotenodesis healing after remplissage was evaluated with magnetic resonance imaging. RESULTS: The average ASES, Rowe, and KSSI scores were statistically significantly higher in group I than group II. The frequency of recurrence was statistically significantly higher in group II. The average loss in external rotation measured with the arm positioned at the side of the trunk was greater in group II and that in abduction was also higher in group II. CONCLUSIONS: Compared to single arthroscopic Bankart repair, the remplissage procedure combined with arthroscopic Bankart repair was more effective to prevent the recurrence of anterior shoulder instability without significant impact on shoulder mobility in patients who had huge Hill-Sachs lesions.

Pedicle screw fixation and posterior fusion for lumbar degenerative diseases: effects on individual paraspinal muscles and lower back pain; a single-center, prospective study.

BACKGROUND: To the best of our knowledge, there have been no reports on the points at which the denervated multifidus and erector spinae muscles become reinnervated after pedicle screw fixation and posterior fusion in patients with lumbar degenerative diseases. Our study was designed to confirm reinnervation of denervated paraspinal muscles following pedicle screw fixation and posterior fusion and to confirm alleviation of the patients' lower back pain (LBP). METHODS: In this prospective study, we enrolled 67 patients who had undergone pedicle screw fixation and posterior fusion. The surgery had alleviated their leg pain, but the patients complained of LBP at the L3-5 level 3 months after the surgery. The patients were divided into two groups (I and II) according to the level at which pain was experienced. Paraspinal mapping scores were recorded preoperatively and 3, 6, 12, and 18 months postoperatively. Oswestry Disability Index and visual analogue scale scores were determined. Regression analyses using a general linear model and a mixed model were performed. RESULTS: Pedicle screw fixation and posterior fusion significantly denervated the multifidus and erector spinae not only in the surgical segment, but also in adjacent segments. Group I patients displayed reinnervation in the denervated erector spinae and multifidus muscles at 12 and 18 months, respectively. In contrast, group II showed reinnervation only in of the denervated erector spinae of the upper segment at 18 months, with no other areas of reinnervation. Postoperative LBP was significantly diminished at 12 months in group I and at 18 months in group II. There was also significantly less LBP at 6 months (prior to reinnervation of the paraspinal muscles). CONCLUSIONS: The denervated multifidus and erector spinae muscles at L4-5, which had been denervated using pedicle screw fixation and posterior fusion, were significantly reinnervated at 18 months postoperatively, whereas patients with denervation at L3-5 had only a tendency to be reinnervated at follow-up. Postoperative LBP in these patients was significantly diminished at the follow-up visits.

Symptomatic mucoid degeneration of the anterior cruciate ligament.

PURPOSE: Mucoid degeneration of the anterior cruciate ligament (ACL) is a little-known entity. The aim of this study was to detail the clinical, radiological, arthroscopic and pathological findings of this condition and to report clinical outcomes following arthroscopic partial excision of the ACL. METHODS: Between 1999 and 2009, 80 knees in 78 patients were diagnosed as having mucoid degeneration of the ACL based on MRI and clinical findings, and subsequently underwent arthroscopic treatment. Of these, 68 knees in 66 patients, with a median age of 51 years (range, 35-75 years), were followed-up for at least one year. RESULTS: All patients had insidious onset of knee pain, while 56 knees (82 %) had associated extension deficits and 36 knees (53 %) had restricted flexion. MRI findings typically showed diffuse thickening and increased signal intensity of the ACL. Arthroscopic examination revealed notch impingement and bulging of hypertrophied ACL into lateral compartments. Associated lesions included meniscal tears in 33 knees and chondral lesions of at least Outerbridge grade 2 in 56 knees. All knees underwent arthroscopic partial excision of the hypertrophied ACL, with three undergoing preoperative and 30 undergoing concomitant meniscectomies. Pain relief was achieved in 58 of 62 knees (94 %) following partial excision of the ACL. Extension deficits were normalized in 49 of 56 knees (88 %), and restricted flexion was normalized in 33 of 36 affected knees (92 %). Four knees of four patients had postoperative symptoms of anterior instability. CONCLUSIONS: Pain and limitation of motion due to mucoid degeneration of the ACL can be improved by arthroscopic partial excision of the ACL with or without notchplasty. However, one potential complication is the development of postoperative symptoms of anterior instability. LEVEL OF EVIDENCE: Retrospective study, Level IV.

3D CT analysis of femoral and tibial tunnel positions after modified transtibial single bundle ACL reconstruction with varus and internal rotation of the tibia.

INTRODUCTION: We analyzed the location of femoral and tibial tunnels by three-dimensional (3D) CT reconstruction images after modified transtibial single bundle (SB) anterior cruciate ligament (ACL) reconstruction, creating a femoral tunnel with varus and internal rotation of the tibia. MATERIAL AND METHODS: Data from 50 patients (50 knees) analyzed by 3D CT after modified transtibial SB ACL reconstructions were evaluated. 3D CT images were analyzed according to the quadrant method by Bernard at the femur and the technique of Forsythe at the tibia. RESULTS: The mean distance of the femoral tunnel center locations parallel to the Blumensaat's line was 29.6%±1.9% along line t measured from the posterior condylar surface. The mean distances perpendicular to the Blumensaat's line were 37.9%±2.5% along line h measured from the Blumensaat's line. At the tibia, the mean anterior-to-posterior distance for the tunnel center location was 37.8%±1.2% and the mean medial-to-lateral distance was 50.4%±0.9%. DISCUSSION: The femoral and tibial tunnels after modified transtibial SB ACL reconstruction creating a femoral tunnel with varus and internal rotation of the tibia (figure-of-4 position) were located between the anatomical anteromedial and posterolateral footprints.

Recurrent malignant fibrous histiocytoma in psoas muscle: a case report.

Malignant fibrous histiocytoma is one of the most common sarcomas that occur in soft tissue, it usually develops in old age individuals and the incidence is similar between the genders. We report here on a case with invasive local recurrence after surgical resection of a malignant fibrous histiocytoma that occurred in the left psoas muscle of a 69-year-old male patient. The patient was first admitted to our hospital with a primary lesion in the left lower abdomen, as seen on magnetic resonance imaging. We report here on a rare case of a malignant fibrous histicytoma in the psoas muscle.

Post-traumatic Lumbar Epidural Hematoma with Neurology: Report of 1 Case.

The purpose of this study was to report a case with post-traumatic spinal epidural hematomas with abnormal neurologic findings, which is uncommon. A 40-year-old man presented at our clinic after a blunt trauma caused by a traffic accident in which he was a pedestrian. After admission, abnormal neurologic symptoms developed including loss of sensation and motor function in his left lower extremity. Magnetic resonance imaging demonstrated a spinal epidural hematoma with 40% canal stenosis at the L5-S1 level. Decompression including hematoma evacuation was done. Symptoms started to be reduced 18 days after operation. He was treated conservatively with medications and all symptoms resolved completely during admission and there were no further neurologic sequelae. Post-traumatic lumbar spinal epidural hematoma with abnormal neurologic findings is an uncommon condition that may present belatedly after trauma with significant neurologic compromise.
