RESUMEN
UNLABELLED: Computed tomography (CT) frequently is used to determine torsional abnormalities. However, its use in clinical practice may be limited. We present a new method for measuring tibial torsion using conventional radiographs. We compared the method with several clinical methods and with CT measurement in 44 lower extremities of 25 subjects. The radiographic method agreed well with all of the clinical methods, and this agreement was better than agreement between CT and clinical examination. The best agreement was between thigh-foot angle and the radiographic method. The proposed radiographic measurement is a practical method for evaluation of tibial torsion in outpatient clinics without the need for specialized equipment. LEVEL OF EVIDENCE: Level II, diagnostic study.

Minimally invasive percutaneous plate osteosynthesis (MIPPO) has well-documented biological advantages and appears to be a reasonable treatment option for complex femoral and tibial fractures. However additional radiation exposure during reduction of the fracture, application of the plate to the bone and screw fixation is one of the disadvantages of this technique. We describe a technical trick for screw fixation in MIPPO with locking compression plates which decreases the duration of fluoroscopy use during the operation.

Malignant fibrous histiocytoma of bone is the osseous counterpart of the tumor in soft tissue. It is a rare primary bone tumor, and there have been conflicting reports on its grades of malignancy. The appendicular skeleton, especially the femur, is the most common site of involvement, whereas the calcaneus is rarely involved. We describe a primary malignant fibrous histiocytoma of the calcaneal bone in a 21-year-old man. The patient underwent neoadjuvant and adjuvant chemotherapy and below-the-knee amputation, and no local recurrence or metastasis was noted after 2 years of follow-up.
