RESUMEN
INTRODUCTION AND IMPORTANCE: Periosteal ganglion cyst is a rare disorder, found only in 55 out of 100,000 people annually. Periosteal ganglion location may cause partial external cortical destruction with irregular saucerization and erosion. This report presents a rare case of periosteal ganglion cyst that occurred of the cruris sinistra. CASE PRESENTATION: A male patient, 68 years old, came with complaint of a lump in the left cruris since one year ago. Nine months later, the lump has increased in size like a chicken egg and still felt painless. MRI result revealed a well-circumscribed multilocular cystic lesion in the peri-osseous soft tissue of the tibia. We performed directly excisional biopsy within the mass, and the histopathology result was periosteal ganglion cyst. CLINICAL DISCUSSION: The exact pathogenesis of periosteal ganglion is unclear. Synovial herniation and mucoid degeneration of the connective tissue of the periosteum are two suggested mechanisms. In some cases, ganglion cysts may compress nearby nerves. Surgical treatment is recommended for patients who still experience symptoms after non-surgical management has failed. Complete resection of the cyst and surrounding periosteum is recommended to prevent recurrence. After 6 months post-operative follow up clinical examination, no recurrence symptoms founded on the patient. CONCLUSION: Periosteal ganglion is a rare lesion and may mimic other bone surface lesions. Resection of the periosteal ganglion cyst with surrounding periosteum is important to prevent recurrence.
RESUMEN
INTRODUCTION: Every emergency surgery performed is aimed at saving lives; however, during COVID-19 pandemic, surgeries are often postponed. Many existing recommendations take into account postponing surgery during a pandemic. How these surgeries can lead to increasing infection rates has not been widely published. This study aims to investigate the relationship of emergency orthopaedic surgery and the incidence rate of COVID-19. PRESENTATION OF CASE: This was a case series of 14 patients. The study was performed at the emergency department unit at a national tertiary hospital in Jakarta, Indonesia. A total of 14 patients underwent orthopaedic surgery in the emergency room of our institution. The mean age of the subjects was 40.07 ± 20.5 years. Twelve (85.7%) were male patients and 2 (14.3%) were female patients. The average duration of surgery was 125 minutes. The most used type of anaesthesia was general anaesthesia for 6 operations (50%). Patients were hospitalized for an average length of 4 days. Three patients had infiltrates found on plain x-ray examination, which required further examination to determine whether the cause was COVID-19 infection or not. There was no ground glass appearance (GGO) in the three patients in further follow-up examination. CONCLUSIONS: We found that emergency orthopaedic surgery was not associated with increasing number of COVID-19 cases. Factors including duration of surgery, length of stay, types of anaesthesia and comorbidities were also not associated with COVID-19 cases in this study.
RESUMEN
INTRODUCTION: Current treatment in treating patient with osteosarcoma is combination of chemotherapy and surgery, either limb-sparing or limb-ablation surgery. One challenge in limb-sparing technique in children is how to deal with the remaining growth of the bone. We created a limb-sparing reconstruction technique that can be fitted in many types of hospital and have a good functional outcome. CASE PRESENTATION: We reported a case of 13-years-old female with left knee pain since 8 months prior hospital admission with previous treatment to a bone setter and open biopsy at previous hospital. Histopathological findings demonstrated osteosarcoma. The patient had a neoadjuvant chemotherapy and followed with limb-sparing surgery. We performed wide excision of proximal tibia and reconstruction using a bone on polyethylene hemiarthroplasty system of the knee joint. Patient then continued on adjuvant chemotherapy. Later on, local recurrence occurred and we performed excision again. Within one year, the patient could walk full weight bearing, perform daily activities with no limitation and no pain, and she had MSTS score of 21. DISCUSSION: Limb-sparing surgery remains a challenging procedure in skeletally immature patients. This bone on polyethylene technique would be functional due to high adaptability in paediatric patients in order to decrease the number of surgeries until the final goal of limb equalization. CONCLUSION: Bone on polyethylene hemiarthroplasty system enables good and reliable functional outcome while maintaining the knee joint for daily activity. It can be chosen as one of viable options in treating osteosarcoma around the knee joint in children.
RESUMEN
INTRODUCTION: Neglected shoulder dislocation is a rare case and may be accompanied by pathological changes in bony and soft tissue structure. Therefore, it requires extensive surgical procedure. Until now, there is no standard treatment protocol to overcome this case and it is still a challenging case. PRESENTATION OF CASE: We presented a 27-year-old male patient with deformity on his left shoulder. The patient has suffered a ten-month-neglected anterior shoulder dislocation with a Hill-Sachs lesion. The treatment was open reduction combined with Latarjet procedure. Evaluation of treatment was performed three months after surgery. DISCUSSION: Management of a neglected shoulder dislocation, especially with signiï¬cant bony defects, is challenging and cannot be managed with standard surgical technique because of severe soft-tissue contracture and imbalance as well as bone deï¬ciency. Chronic locked anterior shoulder dislocation is a difficult condition for both patient and clinician. In addition to that, the treatment results can be unsatisfactory. Latarjet procedure has been shown to be effective for the treatment of recurrent anterior shoulder dislocation with a large glenoid osseous defect which might justify the application of this procedure for the treatment of neglected anterior shoulder dislocation. CONCLUSION: Open reduction combined with Latarjet procedure performed for treatment of neglected anterior shoulder dislocation was found to have a high rate of successful in preventing further dislocation of the shoulder joint although the high risk of osteoarthritis of the shoulder joint can still persist.
RESUMEN
INTRODUCTION: Non-union due to large bone loss often causes significant long-term morbidity. We incorporate the use of allogeneic umbilical cord-derived mesenchymal stem cells (UC-MSCs) as part of the diamond concept of regenerative medicine in a case of infected non-union fracture. PRESENTATION OF CASE: We reported a 54-year-old female patient presenting with pain on the right thigh. She was previously diagnosed with a closed fracture of the right femoral shaft and underwent four surgeries before finally being referred to Dr. Cipto Mangunkusumo General Hospital with infected non-union of the right femoral shaft. The patient was treated with a combination of UC-MSCs, bone morphogenetic protein-2 (BMP-2), Hydroxyapatite (HA), and mechanical stabilization using Masquelet Technique. The combination of allogeneic MSCs, BMP2, HA, and Masquelet Technique was successful in creating new bone with no apparent side effects. DISCUSSION: Bone loss might be caused by external factors (true defects), or structural loss of the existing bone. The combination of allogeneic UC-MSCs, BMP-2, HA and an induced membrane technique pioneered by Masquelet allowed for faster regeneration process and more optimal bone healing. This paper aims to assess and compare the result of such procedures with the previous four surgeries done to the patient, which did not yield satisfactory results. CONCLUSION: The application of allogeneic UC-MSC, BMP-2, HA and Masquelet technique as proposed in the diamond concept is a viable method in treating critical-sized bone defect and provides an effective way to overcome non-union caused by large defect.
