Management of grade III supracondylar fracture of the humerus by straight-arm lateral traction.

Supracondylar fracture of the humerus is a common upper limb fracture in children for which treatment is controversial and often technically difficult, and complications are common. Cubitus varus is the most prevalent complication encountered in such fractures, with a mean incidence rate of 30%. A variety of methods for treating displaced fractures have been recommended. We reviewed 20 cases of severely displaced grade III supracondylar fractures of the humerus in children. There was marked swelling and distorted local anatomy in all these fractures, which were managed conservatively with straight-arm lateral traction. The patients were treated in skin traction for 2 weeks, following which they commenced physiotherapy. The traction was applied with the arm at 90 degrees of abduction and the forearm in supination. None of the patients developed any complication, and all had the full range of movements. None had cubitus varus deformity, and none of these patients required further surgical treatment. There was a complete patient and parent satisfaction. Open or closed reduction with internal fixation is the most common method of treating these injuries, however in some cases this can be very difficult and dangerous. If the local anatomy and swelling do not allow this treatment then non-operative measures have to be adopted. We conclude that straight-arm lateral traction is a safe and effective method of treating these fractures, especially when the local anatomy is disturbed and the swelling makes operative intervention relatively more risky and difficult. Moreover, this method is also appropriate in areas where access to specialised centres in treating these injuries is either difficult or delayed.

Bilateral pedicle stress fracture in the lumbar spine of a sedentary office worker.

A case of bilateral pedicle fracture in the lumbar spine of a sedentary office worker is being presented. No such case has been reported in the literature previously. Bilateral pedicle fracture is a rare entity. Few cases have been reported in literature. All the reported cases had some underlying causative factors like degenerative spine disease, previous spinal surgery or stress-related activities, e.g. athletes. Our case is a 36-year-old sedentary office worker with none of the factors mentioned. We present a case of a 36-year-old sedentary worker with long-standing low backache. There were no root tension signs. Plain radiographs were inconclusive. The patient had a CT scan. The CT scan revealed long-standing defects in the pedicles of L2 vertebra with pseudoarthrosis. Infiltration with anaesthetic relieved the symptoms. Our patient was managed conservatively with spine rehabilitation physiotherapy program. Pedicle fracture can develop due to abnormal stresses in the pedicle either because of previous spinal surgery or spondylitic changes in the spine. Bilateral pedicle fracture in the absence of these conditions is extremely rare.

Quality assurance in nuclear medicine--biological quality control of radiopharmaceuticals.

Quality assurance is the sum of all parameters concerning the preparation and control of a finished product. It is a wide term commonly used for the confirmation and validity of various ways and measurements adopted to obtain a high quality procedure for intended use with guaranteed performance. Biological quality control of pharmaceutical products becomes essential as they are ultimately to be consumed by living organisms, in particular the humans. In this review, we have discussed the importance and significance of biological quality control in nuclear medicine. The current and new procedures for sterility, apyrogenecity and the biodistribution quality control, have been discussed and evaluated in view of the future needs and modern trends in this important area of research.
