The subject under discussion here is one of the most frequent and most typical fractures in children. The use of Kirschner pins is not in question, but their number and position is. We present here a biomechanical analysis of how the train force affects the fissure in supracondylar fractures of the humerus with different forms of osteosynthesis using Kirschner pins, and how stable the osteosynthesis is. The experiments were carried out at the Laboratory of Biomechanics in the Institute of Anatomy of the Medical Faculty of Zagreb.
Fifty patients up to 15 years of age with simple bone cysts were treated at the Department of Pediatric Surgery at the Children's Hospital Zagreb. There were 35 boys and 15 girls with 26 humeral cysts, 15 femoral cysts, 8 tibial cysts, and 1 radial cyst. There was one case of multilocularity of a simple bone cyst (in the humerus and femur). Among those cysts, 19 were multicameral (in the femur and humerus). The size of cysts was determined with regard to the length of the affected bone. Cysts involving up to one tenth of the bone length were defined as small, those up to one fifth as medium, and those exceeding one fifth of the bone length as large. Small cysts were followed up, medium ones were treated surgically in case they did not heal after pathologic fracture, and large cysts were treated surgically without delay. The surgery included opening the cyst wall, curetting the wall epithelium, rinsing with peroxide, opening the medullar canal, and filling the cavity with lyophilized bone. If necessary, a thin "old" Küntscher nail was inserted to achieve stability of fragments and to keep the medullar canal free. The medullar canal was opened in 38 surgically treated patients, and there were 36 good results. In the patients who had the medullar canal opened during surgery, there were fewer recurrences. Healing time was shorter than reported in the literature, even more so if the thin Küntscher nail was used.
BackgroundChronic abdominal pain (CAP) is a serious medical condition which needs to be approached with great attention. Chronic abdominal pain may be caused by entrapment of cutaneous branches of intercostal nerves (ACNES).ObjectivesThe aim of this study is the surgery for abdominal wall pain which caused by cutaneous nerve entrapment in children during last 5 years.Materials and MethodsIn all children with ACNES, we tried conservative treatment with anesthetic and steroid injections. In children who were refractory to conservative treatment, we received surgical procedure like sectioning the entrapped nerve to obtain relief.ResultsIn 12 pediatric patients with chronic abdominal pain, we diagnosed ACNES. Each presented with abdominal pain and a positive Carnett sign. Local nerve blocks using anesthetic and steroid injections are the treatment. In all patients, we tried with local nerve block. In 3 patients, pain improvement occurs in the few minutes, and they were without pain after 5 days. In other 4 patients required a reinjection for pain recurrence. In one patients pain was gone. The maximum reinjection was 3. In other 5 patients, we did operative treatment like sectioning the entrapped nerve.ConclusionsSome children with CAP have ACNES. In all children with ACNES, we recommended local nerve blocks. If the local block in 3 times is not helping, neurectomy of the peripheral nerve is method of choice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
