One of the most prevalent gait dysfunctions is the intoeing gait. Femoral derotation osteotomy is the common treatment for internal rotation gait in cerebral palsy. We now present 3D-gait analysis data of the hip rotation in gait before and after femoral derotation osteotomy. We analysed the influence of the age at the index operation on the risk of recurrence and the surgical technique. Methods: We included 48 patients treated with femoral derotation osteotomy during a single event of multi-level surgery. Mean hip rotation in standing was measured before and after femoral derotation osteotomy (FDO). The patients were divided into two groups of different age and in a second analysis into two groups with the osteotomy in different locations, either inter-trochanteric (DO proximal) or supracondylar (DO distal). Results: Age at FDO and surgical technique had no influence on the results. However, the variance of the results was very high. Differences were found in the walking speed between the DO proximal and DO distal groups. The walking speed in the group of distal femoral osteotomy was higher. This difference was not significant, but there was a trend to proximal osteotomy in slower walkers. Significant improvements in IRG after FDO were found in our investigation. Our results indicate that FDO as a part of single-event multilevel surgery SEMLS provides a satisfactory mean overall correction of IRG. The results were independent of the age at the index operation and the location of the osteotomy."],["dc.identifier.doi","10.1055/s-0035-1557934"],["dc.identifier.isi","000370051900017"],["dc.identifier.pmid","26468922"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/35199"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Thieme Medical Publ Inc"],["dc.relation.issn","1864-6743"],["dc.relation.issn","1864-6697"],["dc.title","Femoral Derotation in Children with Cerebral Palsy - Does the Result Depend on the Age at Operation and the Kind of Surgery?"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

To date there is no evidence for SEMLS in adults with BSCP and the intervention remains focus of debate. Methods This study analysed the short-term outcome (mean 1.7 years, standard deviation 0.9) of 97 ambulatory adults with BSCP who performed three-dimensional gait analysis before and after SEMLS at one institution. Results Two objective gait variables were calculated pre-and post-operatively; the Gillette Gait Index (GGI) and the Gait Profile Score (GPS). The results were analysed in three groups according to their childhood surgical history (group 1 = no surgery, group 2 = surgery other than SEMLS, group 3 = SEMLS). Improvements in gait were shown by a significant decrease of GPS (p = 0.001). Similar results were obtained for both legs (GGI right side and left side p = 0.01). Furthermore, significant improvements were found in all subgroups although this was less marked in group 3, where patients had undergone previous SEMLS. Discussion SEMLS is an effective and safe procedure to improve gait in adults with cerebral palsy. However, a longer rehabilitation period is to be expected than found in children. SEMLS is still effective in adult patients who have undergone previous SEMLS in childhood."],["dc.identifier.doi","10.1302/0301-620X.98B2.36122"],["dc.identifier.isi","000369633400022"],["dc.identifier.pmid","26850437"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/41498"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","British Editorial Soc Bone Joint Surgery"],["dc.relation.issn","2049-4394"],["dc.title","Multilevel surgery in adults with cerebral palsy"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

In addition to contracture of the hip joint, in up to 65 % of cases patients suffer from pain which leads to further loss of function and often to limitations in important basic functions, such as lying, care, sitting, standing and transfer. In order to avoid hip dislocation and to be able to implement therapy at an early stage, screening programs have been developed in recent years which clearly demonstrate the risks of hip displacement in ICP depending on the ability to walk. An investigation of the natural course is practically impossible because as a rule patients with painful neurogenic hip displacement receive surgical therapy. In this study 96 patients with high hip dislocation grade IV on the Tonnis classification were included and 68 could be followed up. The average age at the time of surgery was 10.9 years and the mean follow-up period was 7.7 years. In the postoperative course 6 out of 91 reconstructed hips became redislocated and a proximal femoral resection was carried out in one female patient. The migration index according to Reimers was 14.0 % at the time of the follow-up examination. Revision procedures can be avoided by screening programs. These should be strived for so that the neuro-orthopedic treatment on operation planning is not first initiated when pain occurs and revision procedures, such as angulation osteotomy or proximal femoral resection can be avoided. The reconstruction should also involve minimal deformation of the femoral head. In order to implement this, the interdisciplinary cooperation between neuropediatricians, social pediatriatricians and neuro-orthopedists should be intensified in the future."],["dc.identifier.doi","10.1007/s00132-014-2315-1"],["dc.identifier.isi","000341377200002"],["dc.identifier.pmid","24816981"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/32520"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","1433-0431"],["dc.relation.issn","0085-4530"],["dc.title","Long-term results of reconstructive surgery in infantile cerebral palsy patients with high hip dislocation.

However, despite bilaterally increased femoral anteversion asymmetric internal rotation gait is often found. Femoral derotation osteotomy (FDO) is commonly performed bilaterally. Variable functional outcomes are reported especially in cases with mild internal hip rotation during gait and abnormal preoperative pelvic rotation. A major question is if a unilateral treatment of the more involved side in asymmetric cases leads to a comparable or even superior outcome. One hundred and nine children with spastic bilateral CP treated with FDO with pre- and 1-year postoperative 3D gait analysis were retrospectively collected. The asymmetry was calculated from the preoperative difference between both limbs in hip rotation obtained by 3D gait analysis. Twenty-eight children with asymmetry larger than 20 degrees were selected and classified into two groups, according to whether they obtained a unilateral or bilateral FDO. Preoperative clinical examination and pre- and postoperative hip and pelvic rotation in gait analysis on the more and the less involved side did not differ significantly between both groups. Interestingly, in both groups, hip rotation did not change significantly in less-involved limbs, although intraoperative derotation averaged 25 degrees. After unilateral FDO a significant change in pelvic rotation resulted, whereas this was not found after bilateral FDO. The results of this study suggest that unilateral FDO in children with asymmetric internal rotation gait leads to a comparable functional outcome compared to bilateral treatment. Furthermore, it was shown for the first time that considering the asymmetry has a positive effect on pelvic rotation. (C) 2015 Elsevier B.V.
