RESUMO
Patellar tumors are rare and are usually benign as opposed to malignant tumours. The most frequent benign lesions of patella are giant cell tumor (common in adults), chondroblastoma and osteoid osteoma. A solitary exostosis is the most common benign bone tumor which occurs around the growth plate of long bones. The treatment of choice is extra periosteal resection of exostosis and ensuring complete removal of cartilaginous cap. Indications of surgery are when the exostosis is interfering or disturbing the growth of extremity, malignant transformation, presence of bone erosion, neurovascular compression, interference with joint motion, bursitis, fracture through the stalk and cosmesis. We report a rare case in an adult patient with an extra-articular skeletal osteochondroma of the patella located antero - superiorly which presented as an enlarged bursa and a bony swelling over knee joint.
RESUMO
Ulnar nerve injury in closed fracture of forearm in children is uncommon.Commonly, neurapraxia is the reason for this palsy but other severe injuries or nerve entrapment has been reported in some cases. The importance of diagnosis concerning the types of the nerve injury lies in the fact that they have totally different management.We present a case of ulnar nerve deficit in a child following a closed fracture of the forearm bones. It is imperative to diagnose exact cause of palsy as it forms the basis for treatment. MRI scan can help diagnosis and accordingly guide the management. Simple nerve contusion should be treated conservatively, and exploration with fixation of the fracture should be done in lacerations and entrapments of the nerve. Surgery is not the treatment of choice in cases that could be managed conservatively.
