Spinal epidural hematoma (SEH) can occur naturally or traumatically and is most common in patients with an underlying disease of the vascular structure or coagulation disorder. Most SEHs occur naturally for no apparent reason, and epidural hematoma caused by trauma is less common, comprising 1.0%-1.7% of total spinal injuries. Few reports of SEH induced cauda equine syndrome resulting from low-energy injury caused by osteoporotic vertebral compression fractures are available. The authors experienced a case of delayed SEH after hemorrhage due to a low-energy injury in an elderly patient. No cases in Korea have been reported; therefore, this case is reported with a review of the relevant literature.

Spinal adhesive arachnoiditis is an inflammation and fibrosis of the subarachnoid space and pia mater caused by infection, trauma, spinal vascular anomalies, and iatrogenic (surgery and/or puncture). Adhesive arachnoiditis develops various symptoms and signs (gait disturbances, radiating pain, paralysis, and incontinence). On the other hand, adhesive arachnoiditis associated with cauda equina syndrome has not been reported in Korea until now. The authors experienced cauda equina syndrome caused by adhesive arachnoiditis of the lumbar spine with satisfactory results following decompression. We report this case with a review of the relevant literature.

As the elderly population increases, the incidence of lumbar fusion is increasing, and there has been increasing interest in rapid rehabilitation and functional recovery after surgery. Enhanced recovery after surgery program and multimodal pain control methods can reduce the complications and allow rapid recovery. Various methods have been used to increase the fusion.

Spinal hematomas are a rare but serious complication that is typically observed in the epidural space. Spinal subdural hematomas are a dangerous clinical situation because of their potential to cause significant compression of the neural elements and can be mistaken easily for spinal epidural hematomas. This paper reports a case of a severe whole lumbar subdural hematoma after a simple epidural injection that was treated with surgical decompression with excellent clinical results.

Medial knee joint pain is a common problem in the field of orthopedics. In these patients, a high resolution ultrasound examination can reveal medial collateral ligament (MCL) bursitis, meniscal cyst, degeneration changes to the MCL and meniscal protrusion etc. Prolotherapy is effective in these patients. The author performed prolotherapy for MCL bursitis of the knee joint, and confirmed the disappearance of the bursitis using high resolution ultrasound.

The incidence of postoperative ileus (POI) after colonic and abdominal surgery is high. On the other hand, the reported incidence after lower extremity reconstruction ranges from 0.3% to 4.0%. This paper reports an 81-year-old woman who expired due to POI at six days after primary total knee arthroplasty. The risk factors, diagnosis, preventive methods, and treatment of POI were also investigated through literature reviews.

The radiographic findings of an osteolytic lesion in the knee may indicate numerous possible impressions. Furthermore, osteolysis is a possible cause if there is a surgical history of total knee arthroplasty (TKA). The authors diagnosed osteolysis of the fibular head after aseptic loosening of the tibial component of a cemented TKA in an 83-year-old female patient who visited with right knee pain and report their treatment with revision TKA along with a literature review.

Anaplastic large cell lymphoma (ALCLs) are a group CD30-positive mature T-cell lymphomas, an uncommon subtype of non-Hodgkin lymphomas, characterized by diverse clinical and genetic features. Among the types of ALCL, anaplastic lymphoma kinase (ALK)-negative ALCL, though typically involves the lymph nodes, can infrequently invade other tissues. When soft tissue involvement occurs, it may mimic the clinical presentation of infectious diseases, leading to potential misdiagnosis. Therefore, a histological examination is necessary to differentiate between ALK-negative ALCL and similar phenotypes associated with infectious conditions. This paper reports a case of ALCL, initially misdiagnosed as an infection.

Purpose: No attempt has been made to identify the relationship between the study characteristics and citation rates of articles published in the Journal of the Korean Orthopaedic Association (JKOA). This study classified the study characteristics of articles in the JKOA and analyzed the relationship between the study characteristics and citation rates. Materials and Methods: A cohort study was conducted on all articles published from February 2001 to December 2015. Three independent reviewers classified the articles according to the article type, material, time of the study, design, clinical categories, number of authors, and number of cases. The citation numbers of each article by other journals were taken in January 2020. Univariate analyses were conducted to assess the effect of each characteristic, and multivariate linear regression analysis was performed to analyze the overall relationship between the characteristics and the citation rates. Results: A total of 1,640 articles were published from 2001 to 2015, and 724 articles were cited more than once. The articles published in 2009 had the highest average number of citations. Original articles had the highest citation rates, followed in descending order by surgical techniques and reviews, instructional course lectures, and case reports (p<0.001). Among the case reports, articles dealing with general trauma scored significantly higher average citations (mean=1.5, p=0.006). Among the original articles, articles on general orthopedics had the highest citation rates, followed in order by clinical articles and experimental articles. Among the clinical articles, epidemiologic studies (mean=5.0, p<0.001) and studies on the spine (mean=1.7, p<0.001) recorded significantly higher citation rates than the others. Conclusion: Of all the articles published in the JKOA from 2001 to 2015, articles dealing with general trauma had the highest citation rates among case reports. Among the original articles, epidemiologic studies and studies concerning the spine were cited significantly more than others.
