When evaluating patients with neurofibromatosis and scoliosis, a careful search for the evidence of dystrophic changes should done, because prognosis and management depend highly on the presence of these changes. Preoperative imaging studies including computed tomography or magnetic resonance imaging are recommended, especially in cases of dystrophic scoliosis, to detect unrecognized intraspinal lesions. The radiographic findings and the response to treatment in patients with nondystrophic scoliosis are similar to those in patients with idiopathic scoliosis, and the same decision-making process for idiopathic scoliosis is applicable. Careful follow-up evaluation is mandatory, however, because of the tendency for extraordinary progression to occur with growth. Brace treatment of the short, angulated, dystrophic curves is ineffective; early and aggressive surgical intervention is strongly recommended. In most cases, dystrophic curvatures are best treated with combined anterior and posterior spinal arthrodesis. The fusion area should be generous, and the entire structural area of the deformity both anteriorly and posteriorly should be fused.
We report the results of a one-stage rotational osteotomy of the proximal third of the ulna and distal third of the radius with segmental bone resection for treating congenital radioulnar synostosis. We retrospectively reviewed 25 patients (28 forearms) treated by operation. Patients were divided into two groups according to the method of internal fixation at the osteotomy sites. In Group 1 the ulnar osteotomy was stabilized with an intramedullary pin and in Group 2 no fixation was used. The average forearm position improved from 47° pronation before surgery, to 27° supination after surgery. There were no statistically significant differences between the two groups in surgical outcomes. One-stage rotational osteotomy of the proximal third of the ulna and distal third of the radius with segmental bone resection is a simple and safe treatment for patients with congenital radioulnar synostosis. Internal fixation at the osteotomy site seems to be unnecessary. Level of evidence: Level 4.
We describe our experience with the 'four-in-one' procedure for habitual dislocation of the patella in five children (six knees). All the patients presented with severe generalised ligamentous laxity and aplasia of the trochlear groove. All had a lateral release, proximal 'tube' realignment of the patella, semitendinosus tenodesis and transfer of the patellar tendon. The mean age at the time of the operation was 6.1 years (4.9 to 6.9), and the patients were followed up for a mean of 54.5 months (31 to 66). The clinical results were evaluated using the Kujala score.There has been no recurrence of dislocation. All the patients have returned to full activities and the parents and children were satisfied with the clinical results. The mean Kujala score was 95.3 (88 to 98). Two patients had marginal skin necrosis which healed after debridement and secondary closure. These early results in this small group have shown that the 'four-in-one' procedure is effective in the treatment of obligatory dislocation of the patella in children with severe ligamentous laxity and trochlear aplasia.
Tibial lengthening with use of the Ilizarov external fixator over an intramedullary nail results in new bone formation of a quality equal to that obtained with the conventional Ilizarov method; however, it reduces the duration of external fixation and the rate of complications.
PurposeThe aims of this study were to review our cases of missed Monteggia fracture treated by open reduction of the radial head with or without ulnar osteotomy and to investigate the indications for open reduction alone in surgical treatment of missed Monteggia fracture.Materials and MethodsWe retrospectively reviewed 22 patients who presented with missed Monteggia fracture. The patients' mean age at the time of surgery was 7.6 years. The mean interval from injury to surgery was 16.1 months. The surgical procedure consisted of open reduction of the radiocapitellar joint followed by ulnar osteotomy without reconstruction of the annular ligament. The mean period of follow-up was 3.8 years. Radiographic assessment was performed for the maximum ulnar bow (MUB) and the location of the MUB. Clinical results were evaluated with the Mayo Elbow Performance Index and Kim's scores.ResultsFive patients underwent open reduction alone, and 17 patients underwent open reduction and ulnar osteotomy. When the MUB was less than 4 mm and the location of the MUB was in the distal 40% of the ulna, we could achieve reduction of the radial head without ulnar osteotomy. The radial head was maintained in a completely reduced position in 21 patients and was dislocated in one patient at final follow-up.ConclusionOpen reduction alone can be an attractive surgical option in select patients with missed Monteggia fracture with minimal bowing of the distal ulna. However, ulnar osteotomy should be considered in patients with a definite ulnar deformity.
Salvage surgery can be of benefit to patients with CP with chronic painful hip dislocation, but should be limited to selected patients considering complications.
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.
