RESUMEN
Eleven patients (8 males, 3 females) undergoing limb-lengthening procedures were subjected to weekly conventional radiography along with fortnightly skeletal sonography of the distraction site, to assess the rate of new bone production and complications. The radiographs were assessed for: (i) distance between the distracted bone ends, (ii) presence of new bone formation at the distraction site, (iii) regeneration of the cortical outline and (iv) overlaying soft tissue abnormality. The sonographs were assessed for: (i) distance between the distracted bone ends, (ii) rate of new bone formation, (iii) density of the new bone produced, (iv) integrity and continuity of the cortical outline and (v) overlaying soft tissue abnormality. Our results indicate the superiority of sonography over conventional radiographs in: (i) detecting early new bone formation, (ii) establishing cortical and medullary canal remodelling, (iii) detecting soft tissue complications at the distraction site and (iv) determining the presence of fluid collection at the distraction site, in patients with delayed consolidation. Conventional radiographs were more accurate in determining the distance between the two distracted bone ends, and thus the degree of distraction achieved. Ideal assessments of events at the distraction site can be achieved by a combined assessment of conventional radiotherapy and skeletal sonography.

A case of hydatid cyst of the tibia, which manifested as a pathologic fracture is being reported. Pain and swelling of left lower limb with inability to bear the weight were the main features. Tender swelling was also noted at the upper and middle third of tibia. Open biopsy revealed the hydatid cyst wall and scolices of Echinococcus granulosus. Albendazole treatment was followed by curettage and bone grafting.

A rare case of a bizarre parosteal osteochondroma in the foot is presented. The tumour first described in 1983 by Nore et al is rare in any location and has to be differentiated from a juxta-cortical osteosarcoma and a benign osteosarcoma. Its differentiating characteristics are discussed.

A rare case of simultaneous disruption of superior radio-ulnar joint and posterior dislocation of the same elbow in a 6 year old boy is presented. It was possible to achieve the stable reduction by means of closed manipulation, restoring normal function in 6 weeks time. The possible mode of injury is discussed. There are only 4 cases reported of such a divergent elbow dislocation in modern literature.
