RESUMO
Despite common occurrence, congenital talipes equinovarus (clubfoot) is still a subject of controversy. It poses a significant problem with its unpredictable outcome, especially when the presentation for treatment is late. The true etiology remains unknown although many theories have been put forward. A standard management scheme is difficult as there is no uniformity in the pathoanatomy, classification and radiographic evaluation. These differ according to the age of the child and the severity of the condition. The paper discusses these controversies with an emphasis on the proposed etiologies and types of treatment performed.
RESUMO
Sixty percent of open fracture wounds are contaminated at the time of injury. Despite that, the necessity for sequential multiple cultures and sensitivity studies for open fractures and their interpretation are still controversial. Predebridement, intraoperative, postoperative swabs and swabs in established infection for culture and sensitivity study were taken in 33 open tibial fractures over a 6 months period. 39.3% of predebridement swabs grew bacteria with the majority yielding gram-positive organism. None of the patients developed infection with similar organisms. 24.2% of the postoperative swabs grew bacteria, of which 75% were gram-negative. 50% of the patients with positive postoperative swabs developed infection. Thus, the role of sequential multiple cultures and sensitivity studies are not helpful in management of open fracture.

Malignant pelvic tumours often present late, hence a high index of suspicion should be maintain in order to arrive at the diagnosis. This is particularly true for those who have unusual symptoms. A proper planning and staging strategies is required to save the limb, and the limb salvage surgery is at present the surgery of choice to achieve local control and restoring optimum functions of the lower limbs as being illustrated by our three cases.
