1/7. Evaluation of suspected stress fractures.Stress fractures can occur if normal bone is exposed to repeated abnormal stress (fatigue fractures) or if normal stress is placed on bones with compromised elastic resistance (insufficiency fractures). This article describes two patients without a history of excessive stressful activity or apparent metabolic bone disease who developed bilateral distal tibial stress fractures. Different etiologies, clinical presentation, differential diagnosis, and diagnostic imaging modalities of stress fractures are discussed.- - - - - - - - - - ranking = 1keywords = bone disease (Clic here for more details about this article) |
2/7. Three different stages of bone stress reactions of long bones in one patient: case report and review of the literature.INTRODUCTION: The similar clinical and radiological early course of stress fractures and bone tumors can lead to diagnostic misinterpretation. MATERIALS AND methods: A patient is presented who was admitted to our clinic with the diagnosis of similar bone tumors in the distal femur and the proximal tibia. We found an additional localization with high bone turnover in the contralateral proximal tibia; including this lesion, the patient presented with three different types of stress reaction of bone. The final diagnostic decision-making was based on MRI and bone scintigraphy as well as the consideration of localization, age of occurrence, and behavior of malignant bone diseases. Therefore, bone biopsy was not performed. RESULTS: After 8 weeks of partial weight-bearing, the symptoms disappeared, and the patient could return to normal activity.- - - - - - - - - - ranking = 1keywords = bone disease (Clic here for more details about this article) |
3/7. hip pain in a case of hypophosphatemic osteomalacia.Hypophosphatemic rickets, a rare metabolic bone disease, presents mainly in children but has also been reported in several adults. In this report, we describe the case of a man presenting with hip pain and weakness, both of several months' duration, and tested for hypophosphatemic rickets. The patient was eventually referred to a tertiary-care center, where he was diagnosed with bilateral subtrochanteric femoral stress fractures and severe osteopenia secondary to hypophosphatemic osteomalacia. The patient was treated with closed reduction and internal fixation and vitamin d and phosphorus. Outcomes were good at 7-month follow-up.- - - - - - - - - - ranking = 1keywords = bone disease (Clic here for more details about this article) |
4/7. Femoral stress fractures in children.Stress fractures reported in the medical literature almost exclusively affect young athletes, military recruits and patients with metabolic bone disease. The classification of stress-induced bone injury is somewhat confused and includes "fatigue" stress fractures which occur in previously normal bones and "insufficiency" stress fractures which occur in bones weakened by various causes. Femoral stress fractures in children are extremely rare, and we report 5 cases in young patients who sustained their injuries during the course of normal play activities. It is well-known that these lesions can simulate malignant lesions; however, we believe that careful review of the radiographs in the context of the clinical history can in many cases lead to the correct diagnosis being made and obviate the need for further intervention.- - - - - - - - - - ranking = 1keywords = bone disease (Clic here for more details about this article) |
5/7. Sequential metatarsal fatigue fractures secondary to abnormal foot biomechanics.Sequential fatigue fractures of the fourth, second, and third metatarsals in the same foot are reported for a military aviator in the absence of abnormal stresses or underlying bone disease. The likely etiological factor is altered foot biomechanics, as identified in pedobarographic assessment. We have reviewed the literature regarding multiple metatarsal stress fractures.- - - - - - - - - - ranking = 1keywords = bone disease (Clic here for more details about this article) |
6/7. fatigue fractures of the sacrum in children: two case reports and a review of the literature.We present the clinical and radiological features of two children with fatigue fractures of the sacrum. Both patients were active, had no underlying bone disease and presented with insidious onset of low back pain. Plain radiography was non-contributory to the diagnosis. In both patients a focal area of increased activity was present in the lateral aspect of the sacrum on bone scintigraphy, which corresponded to linear medullary sclerosis in the sacral ala demonstrated by computed tomography. magnetic resonance imaging in one patient revealed a linear signal void in the sacral ala on T1- and T2-weighted images. This was surrounded by diffuse low marrow signal on T1-weighted images, and increased marrow signal on T2-weighted images. fatigue fractures of the sacrum should be considered in the differential diagnosis of low back pain in children. An awareness of their appearance on magnetic resonance imaging is important as this modality is increasingly utilised, particularly in children.- - - - - - - - - - ranking = 1keywords = bone disease (Clic here for more details about this article) |
7/7. Case report 772. Stress fracture of the hip secondary to renal osteodystrophy and erosion of ischium due to amyloid deposition.We have reported the case history of a 72-year-old woman who was on hemodialysis for 15 years. Her course was marked by many of the musculoskeletal complications of ESRD including CTS, stromal amyloid deposition of synovium, amyloid cystic degeneration of bone, and inflammation of the synovium due to the deposition of calcium oxalate and calcium pyrophosphate microcrystals. She also had evidence of metabolic bone disease: moderate osteoporosis related to secondary hyperparathyroidism and osteomalacia related to aluminum deposition at the mineralization front. The pathological and radiological findings associated with her bone disease are described.- - - - - - - - - - ranking = 2keywords = bone disease (Clic here for more details about this article) |
