ABSTRACT
Renal osteodystrophy (ROD) is a skeletal complication resulting from pathologic alterations in calcium, phosphate, and bone metabolism. The potential link between bone turnover and bone quality is an important question meriting study because of the relatively high incidence of fractures reported. In this case presents a pathological fracture on a routinely hemodialyzed woman. She complained pain on her left subtrochanteric area after low energy trauma accident. A thickening of the shaft femoral bone cortex was also found, reflecting the osteosclerosis event due to imbalance of proliferation and differentiation of osteoblast with increase bone formation. She also had a blastic lesion on her contralateral shaft femoral during the bone survey, but this finding remains asymptomatic. Decreased osteoclastic activity may contribute to cortical thickening, resulting in overall bone mass increase, which may lead to decreased elasticity of the bone or impaired repair capabilities, therefore increasing the risk of fracture. The blastic lesion that occurred on contralateral side may indicated effect of ROD or primary bone lesion. Careful assessment and holistic management of patients with kidney disease is necessary to achieve optimal outcome. The prevention of falls is also an important strategy to prevent pathological fractures. End stage renal disease (ESRD) have reduced bone mineral density, a risk factor for fracture incidence. Careful anamnesis and clinical examination are needed for diagnosis and management.
ABSTRACT
Multiple myeloma (MM) is a malignant B-cell lymphoproliferative disorder of the marrow, with plasma cells predominating. It is unlikely to encounter rising level of any tumor marker in MM patient. We present a case of 46-year-old female came to the orthopaedic clinic with chief complains of pain on her right arm, left shoulder and right hip after 5 months. The results of the bone survey of these patients showed multiple lytic lesions with a punched-out appearance in calvaria. The expansive lytic mass was seen with cortical destruction in one third proximal metaphysis to diaphysis of humerus with periosteal reaction and surrounding soft tissue mass. The basic metabolic panel (BMP) result of these patient is hipocellular with decrease of erythroid, myeloid, and megakaryocytes activity and there are 30% plasma cells with positive myeloma cells. Therefore, the patient was diagnosed with MM. The laboratory result of these patient also showed elevation of carbohydrate antigen 125 (CA-125) marker to 56 and 92 (normal range is <35). The patient reported herein showed clear signs and symptoms of MM accompanied by elevated level of CA-125 and CA-15.3 tumor markers. Elevated CA-125 values most often are associated with epithelial ovarian cancer, although levels also can be increased in other malignancies such as endometrial, fallopian tube, breast, lung, esophageal, gastric, hepatic, and pancreatic. However, there were no clear mechanism of how a malignant B-cell lymphoproliferative disorder of the marrow stimulates the production of tumor marker such as CA-125.
ABSTRACT
Giant cell tumor (GCT) is a relatively common benign primary bone tumor, commonly seen in end of long bones. Treatment goals for GCT of the distal radius are complete excision of the tumor and preservation of wrist function. Usually it can be treated by en-bloc resection and reconstruction using autogenous non vascularized ipsilateral proximal fibular graft. Authors present a case of twenty two years old female complaining of pain and lump in left wrist since two years ago. The pain worsened since 1 month before consultation, but did not radiate elsewhere. Pain was aggravated by movement and decreased with rest. Physical examination revealed a 3 cm mass with tenderness over left wrist. With clinical suspicion of benign bone tumor on left wrist, further evaluation was needed. Plain radiograph revealed an expansile, lytic lesion and soap bubble appearance on her left distal radius like a GCT. Open biopsy result revealed similar morphology with GCT. Reconstruction by en-bloc surgical excision, followed with non-vascularized fibular bone graft fixed with dynamic compression plate (DCP) and wrist ligament reconstruction and fixation of the head of the fibula with carpal bones and distal end of the ulna using K-wires along with palmaris longus tendon were performed. En-bloc resection of giant cell tumors of the lower end radius is a widely accepted method. Reconstruction with non-vascularized fibular graft, internal fixation with DCP with trans fixation of the fibular head and wrist ligament reconstruction minimizes the problem and gives satisfactory functional results.
ABSTRACT
Background: Metastatic bone disease (MBD) causes a massive morbidity, pain, and disability for the sufferers. Thyroid carcinoma, which is the most common endocrine cancer worldwide, also contributes to the increased rate of MBD, as 60% of patients with thyroid carcinoma experience bone metastasis. An urgency to further analyze the risk factors of bone metastasis in thyroid cancer is necessary in order to prevent and treat this unwanted occurrence earlier and better.Methods: A descriptive retrospective study was conducted using patients’s medical record data obtained from Sanglah General Hospital between January 2013 until March 2019. The variables obtained were sex, age, diagnosis, management, and fracture site.Results: There were 15 patients involved in this study, presenting with pathological fracture due to MBD from thyroid cancer. Ten patients were female (66.7%) and 5 were male (33.3%). According to the age group, 2 patients (13.3%) were <40 years old, 5 patients (33.3%) were >60 years old, while the majority of 8 patients (53.4%) were 40-60 years old. From the pathological result, 9 patients had follicular neoplasm (60%) and 5 patients had papillary neoplasm (33%). The most common site of metastasis was humerus in 7 patients (47%), while the other sites were femur, pelvic, and tibia.Conclusions: According to this series, there are several risk factors related to MBD from thyroid carcinoma, including female gender, the age of 40-60 years old, and follicular type neoplasm. A further study with bigger amount of sample is needed to improve the result.
ABSTRACT
Abstract Tuberculous osteomyelitis is an uncommon form of tuberculosis (TB); the isolated involvement of the wrist joint is particularly rare. The symptoms and clinical manifestation mimic other conditions; hence, careful diagnosis is required. The authors present two cases of patients presenting with soft tissue mass and a lytic bone lesion. The biopsy revealed granulomatous osteomyelitis. Lesion culture identified Mycobacterium tuberculosis. The authors urge clinicians to include TB as a differential diagnosis when investigating the primary cause of lytic bone lesions, even in the absence of pulmonary symptoms or risk factors of TB infection. The inclusion of mycobacterial cultures when analyzing biopsies of lytic bone lesions is also advised.
Resumo A osteomielite tuberculosa é uma forma incomum de tuberculose (TB) e o acometimento isolado da articulação do punho pelo TB é particularmente raro. Os sintomas e a manifestação clínica imitam outras doenças; portanto, um diagnóstico cuidadoso é necessário. Os autores apresentam dois casos de pacientes com massa nas partes moles e lesão óssea lítica. A biópsia revelou osteomielite granulomatosa. A cultura da lesão identificou Mycobacterium tuberculosis. Os autores recomendam que médicos clínicos incluam a TB como um diagnóstico diferencial da causa primária das lesões ósseas líticas, mesmo na ausência de sintomas pulmonares ou fatores de risco de infecção por TB. A inclusão de culturas micobacterianas na análise de biópsias de lesões ósseas líticas também é recomendada.

Chondrosarcoma is the second most frequent malignant bone tumour after osteosarcoma. It most often occurs in the pelvis. Treatment of pelvic chondrosarcoma is a difficult problem for the musculoskeletal oncologist. We report 3 patient with chondrosarcoma in pelvic region that undergoing internal hemipelvectomy. First patient, male 28 y.o. with chondrosarcoma in left iliac wing 11.2cm x 10.8cm x 9.2cm. Second, woman, 47 y.o with chondrosarcoma in right superior and inferior pubic rami 13.7cm x 11.5cm x 14.2cm with soft tissue mass around extended to medial part of proximal thigh. Already done A wide excision of the tumor was performed and we use non-vascularized fibular graft (NVFG) to fill the defect. Last patient, pregnant woman 22 y.o. (16weeks gestational age) with chondrosarcoma in right pubic rami 9.8cm x 11.4cm x 13cm. We already done internal hemipelvectomy without terminating the fetus. The second and third patient confirmed with the histopathology result with chondrosarcoma grade II, and the first patient with chondrosarcoma grade I. After 3month post operatively, all of the patients have no pain, no urinary tract complain. The first patient can ambulatory full weight bearing with no crutches or walker. Second patient ambulatory partial weight bearing with crutches. The last patient ambulatory with wheel chair during the pregnancy. Since chondrosarcomas are unresponsive to chemotherapy or radiotherapy, surgical resection was the only therapeutic solution for these patients. It also reinforce the need of a correct diagnose and collaboration between specialities in the treatment of oncological patients.
