Tuberculosis remains a major international health problem despite advances in radiological diagnosis and antituberculous therapy. Disseminated tuberculous infection affecting a single bone and manifested as multifocal lytic cortical lesions is rare and unusual. We report on a 50-year-old man with multifocal involvement of the femur by tuberculosis and demonstrate positive reaction using tuberculosis-polymerase chain reaction on formalin-fixed, paraffin-embedded histological specimens.
Although general recommendations exist regarding the correct placement of the skin incision and the direction of deep dissection for closed antegrade intramedullary nailing of the femur, in surgical practice simultaneously establishing the correct entry point and exact direction for insertion of the entry instrument in the lateral (sagittal) plane may be difficult. This is due to sub-optimal radiographic images in the lateral plane as a result of the overlying shadows of the pelvis, variations in the degree of rotation of the femur during patient positioning and fracture reduction manoeuvres, variations in the degree of anterior bowing of the femoral shaft and the anatomy of the greater trochanter, and deviations of the plane of deep dissection caused by the glutei muscle fibres. This may lead to the need for several attempts with increased damage to the glutei muscles, high exposure to radiation and the risk of an iatrogenic fracture. The present technical note describes a simple method for swift, easy and accurate access to the medullary canal during closed antegrade femoral nailing.
The reliability of the AO/Orthopaedic Trauma Association classification system has not been evaluated for diaphyseal fractures or fractures attributable to gunshot injuries. Therefore, the current authors assessed its reliability for diaphyseal femur fractures and investigated the effect of a gunshot mechanism of injury. Forty-seven diaphyseal femur fractures, 23 caused by gunshots and 24 caused by blunt trauma, were classified by four observers on two occasions. The interobserver and intraobserver reliability of each level of the AO/Orthopaedic Trauma Association classification was assessed with kappa statistics. Determination of fracture type had substantial interobserver and intraobserver reliability for gunshot and blunt injuries. Reliability decreased at the subsequent levels of the classification. Fractures caused by gunshots compared with those caused by blunt trauma were characterized by significantly lower interobserver agreement on fracture group (k = 0.26 versus 0.45) and subgroup (k = 0.21 versus 0.38). The AO/Orthopaedic Trauma Association classification system has substantial interobserver and intraobserver reliability when evaluating the type of diaphyseal femur fractures. Determination of fracture group and subgroup, however, progressively reduces the reliability of the classification, especially for fractures caused by a gunshot. Diaphyseal femur fractures caused by gunshots, by means of their fracture patterns, cannot be classified reliably with the AO/Orthopaedic Trauma Association classification system.
