Osteoid osteomas consist of a nidus with surrounding sclerotic bone. The differential diagnosis covers a wide range of conditions due to the variable presentation of osteoid osteoma. The natural history is for regression to occur within 6 to 15 years with no treatment; however, this can be reduced to 2 to 3 years with the use of aspirin and non-steroidal anti-inflammatory drugs. Computed tomography-guided percutaneous techniques, including trephine excision, cryoablation, radiofrequency ablation, and laser thermocoagulation, are described.

The purpose of this study was to determine predictors of posttraumatic convulsions in children. Study subjects included children under 12 years of age, who were admitted to the Safdarjang Hospital, New Delhi, during the year 1997 (January to December) after suffering head trauma. The occurrence of first convulsion after head injury was taken as the outcome variable in the study. Medical records were reviewed for data about clinical, radiological and epidemiological features of such children. The study revealed that children younger than 2 years of age (odds ratio, OR 2.96; 95% confidence interval, CI 1.42–6.21), those suffering severe head injuries, i.e. with low Glasgow Coma Score (OR 3.07; 95% CI 1.40–6.77), and those with longer period of unconsciousness after head trauma, especially longer than 12 h (OR 1.71; 95% CI 0.69–4.19) have higher likelihood of suffering convulsions after head injury. However, none of the radiological findings were found to be significantly associated with posttraumatic convulsions.

Rupture of the distal biceps tendon is a relatively uncommon injury. Different methods have been described for its surgical repair. According to published reports, current surgical techniques result in decreased strength and endurance of upper extremity functions requiring supination and flexion. In our anatomic study of 74 cadaveric elbows, we observed that the distal biceps tendon spirals in a predictable manner and has a complex fiber arrangement. Successful surgical repair of a ruptured distal biceps tendon should be predicated on an understanding of the tendon anatomy, but current surgical techniques do not take into account the salient anatomic features of the distal biceps tendon. To our knowledge, there is no description in the surgical literature of the fiber arrangement of the distal biceps tendon. We provide a basis for developing an anatomically accurate protocol for repairing a distal biceps tendon rupture.

The aim of this study was to describe the anatomy of the extensor pollicis brevis tendon, in particular its insertion, in 44 preserved hands from 23 cadavers. We found that only 25% of the tendons were inserted in the conventional way, viz, into the base of the proximal phalanx, and confirmed that the course and insertion of the extensor pollicis brevis tendon varies widely. The importance of these findings to the practice of hand surgery is discussed.
