RESUMO

The three major causes of vertebral body collapse include infection, malignant neoplasia, and trauma and it may be difficult to distinguish between them, particularly in the presence of severe osteoporosis. In 1891, however, Dr Hermann Kümmell, further added another possibility of vertebral body crush; the delayed posttraumatic collapse. As originally described, this rare clinical entity includes patients, who after a trivial trauma and an asymptomatic clinical course they develop a progressive vertebral body collapse and a painful kyphosis. Although more than a century has passed from its initial description, only few cases have been reported in the literature, whereas the main pathologic eliciting event is still under investigation. As a consequence, great controversy exists regarding the discrete features of the clinical course, its radiographic appearance and the histopathological findings. To explain the time lag between the initial trauma and the occurrence of the vertebral collapse, the hypothesis of ischemic necrosis was advanced. Equation of Kümmell's disease with vertebral osteonecrosis, however, has wrongly led many authors to report cases of Kümmell's disease, even in the absence of history of spinal trauma. On the other hand, high coincidence of vertebral osteonecrosis and the pathognomonic radiographic finding of intravertebral vacuum cleft, has further added to the confusion. In this review we present an overview of the literature on Kümmell's disease, focusing on the different proposed eliciting mechanisms. We also highlight controversial subjects on clinical course, diagnosis and treatment of this entity, in an attempt to further clarify patients' inclusion criteria.

RESUMO

Kümmell's disease (KD) is a rare clinical entity and includes patients, who after a trivial trauma and an asymptomatic period, develop a progressive vertebral body collapse and a painful kyphosis. The main pathologic eliciting event still remains unclear. Vertebral body collapse can be the result of infection, malignant neoplasia or trauma. It may be difficult to distinguish among them, particularly in osteoporosis. To explain the time lag between initial trauma and vertebral collapse, the hypothesis of ischemic necrosis was suggested. Many authors considering KD as a case of mere vertebral osteonecrosis have wrongly reported cases of osteonecrosis without a spinal trauma, as KD. The fact that intravertebral vacuum cleft often coexists with vertebral osteonecrosis further added to confusion. Various imaging modalities including bone scan support the diagnosis of KD. It is described that bone single photon emission tomography (SPET) or SPET/computed tomography scintigraphy using dynamic and static, acquisition can identify the chronicity of the lesions.

RESUMO

Over 100 years ago, Dr Hermann Kümmell described a rare clinical entity in which patients, after a trivial trauma and an asymptomatic period, developed a progressive vertebral body collapse and a painful kyphosis. We present the case of a 31years old heavy labourer, fitting Kümmell's criteria. The patient referred to us in an incapacitated state, due to persistent back pain. Radiographic examination revealed a body collapse of L1 vertebra. The patient had no previous medical record, other than a prolonged history of transient back pain episodes, related to heavy-weight lifting. Last attack was 1 year before presentation. Through course of time, he had undergone several clinical and radiological evaluations, by different orthopaedists, on different occasions, including the last episode, with no major findings. After an extensive workup, a percutaneous kyphoplasty of the affected vertebra was performed and a biopsy was obtained. The histologic examination of the specimen revealed vertebral osteonecrosis. A triggering pattern of repetitive spinal loading in hyperflexion is, for the first time, being recognized. We conclude that Kümmell's disease, although a rare condition, should be considered in any patient with refractory back pain symptoms. In such patients, vigorous follow-up turns to be of the essence.

RESUMO

INTRODUCTION: Radical prostatectomy is a standard approach to the management of prostate cancer. As the oncological outcome has improved, focus has drawn to the postoperative amelioration of health-related quality of life (HRQOL). MATERIALS AND METHODS: The instruments that have already been used, or may be used, in assessing the HRQOL postoperatively in men with prostate cancer are presented. RESULTS: Urinary and sexual dysfunction as well as fecal incontinence form the three possible major complications after surgery which affect the patient's quality of life. Meticulous counseling regarding the potential morbidity associated with the operation that may affect the patient's quality of life should be made before the patient gives his informed consent. CONCLUSIONS: Questionnaires only partially help to identify patients with dysfunction, especially sexual and bowel dysfunction, and careful patient counseling with their partners present is the best way to evaluate the presence of dysfunction pre- or postoperatively.
