Multilevel Surgery Improves Gait in Spastic Hemiplegia But Does Not Resolve Hip Dysplasia
Background: Multilevel orthopaedic surgery may improve gait in Type IV hemiplegia, but it is not known if proximal femoral osteotomy combined with adductor release as part of multilevel surgery in patients with hip dysplasia improves hip development. Questions/purposes: We asked whether varus derotational osteotomy of the proximal femur, combined with adductor release, influenced hip development in patients with Type IV hemiplegia having multilevel surgery. Patients and Methods: We retrospectively reviewed 11 children and adolescents with Type IV hemiplegia who had a proximal femoral osteotomy due to unilateral hip displacement to correct gait dysfunction between 1999 and 2006. The mean age at the time of surgery was 11.1years (range, 7 to 16 years). We obtained the Movement Analysis Profile and Gait Profile Score before and after surgery. We also measured the Migration Percentage of Reimers and applied the Melbourne Cerebral Palsy Hip Classification System (MCPHCS). The minimum followup was 2years 3months (mean, 6years 6months; range, 2years 3months to 10years 8months). Results: The majority of gait parameters improved but hip development was not normalized. According to the MCPHCS at last followup, no hips were classified as Grade I, two hips were classified as Grade II, and the remainder were Grade III and IV. Conclusions: Unilateral surgery including a proximal femoral osteotomy improved gait and walking ability in individuals with spastic hemiplegic cerebral palsy. However, hip dysplasia persists. Level of Evidence: Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidenc
Behandlung der kindlichen proximalen Humerusfrakturen
Zusammenfassung: Frakturen des proximalen Humerus im Kindesalter können wegen des hohen Spontankorrekturpotenzials für Fehlstellungen in der Nähe der proximalen Humeruswachstumsfuge in der überwiegenden Mehrzahl der Fälle mit sehr gutem funktionellem Ergebnis konservativ behandelt werden. Ziel dieser Übersicht ist es, die Indikationen und Techniken für die operative Behandlung dieser Verletzungen im Wachstumsalter darzustellen. Indikationen zur primären Reposition und ggf. Stabilisation stellen kosmetisch störende Valgusfehlstellungen bei Kindern und dislozierte proximale Epiphysenlösungen und proximale Humerusfrakturen von vor dem Wachstumsabschluss stehenden Jugendlichen dar, da hier das Remodellingpotenzial fehlt. Während die geschlossene Reposition und perkutane Kirschner-Draht-Fixation von dislozierten proximalen Humerusfrakturen und Epiphysenlösungen sich durch die Möglichkeit die Drahtenden über die Hautoberfläche vorstehen zu lassen und dann ambulant zu entfernen, sowie die meist geringere Durchleuchtungszeit auszeichnet, fehlt dieser Methode die Übungsstabilität im Vergleich zur elastisch stabilen intramedullären Schienung ("elastic stable intramedullary nailing",  ESIN). Die ESIN zeichnet sich dagegen durch Übungsstabilität aus, jedoch um den Preis eines 2.Eingriffes in Narkose für die Metallentfernung. Die für die ESIN notwendige exakte Vorreposition für die korrekte Einbringung der Markschienen erfordert meist eine längere Durchleuchtungszeit im Vergleich zur Stabilisation mit perkutan eingebrachten Kirschner-Drähten. Die Interposition von Weichteilen wie Periost oder selten der Sehne des langen Bizepskopfs vorne im Frakturspalt bedingt einen erheblichen Anteil offener Repositionen (bis 50%) bei operativer Frakturstabilisatio
Conservative treatment and outcome of upper cervical spine fractures in young children: A STROBE-compliant case series.
Cervical spine (C-spine) fractures in young children are very rare, and little information on treatment modalities and functional, radiographic, and patient-reported outcome exists. In this 2-center, retrospective case series, we assessed subjective and functional mid-term outcomes in children aged ≤5 years whose C-spine fractures were treated nonoperatively.Between 2000 and 2018, 6 children (median age at injury: 23.5 months; range: 16-31 months) with C1 or C2 injuries were treated with Minerva cast/brace or soft collar brace at 1 of the 2 study centers. Two patients suffered C1 fractures, and 4 patients had lysis of the odontoid synchondrosis. Overall, 3 children had sustained polytrauma. One child died due to the consequences of massive head injury.For the primary outcome parameter, we recorded subjective symptoms such as pain and functional restrictions due to the sequelae of C-spine injuries at follow-up.Based on medical records, we also assessed the causes of injury, diagnostic procedures, treatments and complications, and time to fracture consolidation.Median follow-up of the 5 surviving children was 51 months (range: 36-160 months). At the latest follow-up, 4 of 5 children did not complain of any pain. One child who sustained an open head injury in combination with a subluxation of the odontoid and undisplaced fracture of the massa lateralis reported occasional headache. All patients experienced complete fracture healing and normal range of motion of the cervical spine.Median duration of cast/brace treatment was 8.5 weeks. Fracture healing was confirmed by computed tomography in all patients.All C-spine injuries were managed with either Minerva cast/Halo brace or soft collar brace without complications.In our retrospective case series, nonoperative treatment of atlas fractures and dislocations or subluxations of the odontoid in young children using Minerva casts or prefabricated Halo braces resulted in good subjective and functional outcomes at mid-term. We observed no complications of conservative treatment of C1 and C2 injuries in young children
Treatment of unstable occipital condylar fractures in children-a STROBE-compliant investigation
Background and objectives: Occipital condyle fractures (OCF) occur rarely in children. The choice of treatment is based on the Anderson–Montesano and Tuli classification systems. We evaluated the outcome of unstable OCF in children and adolescents after halo-vest therapy. Materials and Methods: We treated 6 pediatric patients for OCF, including 3 patients (2 girls, 1 boy) with unstable OCF. Among the 3 patients with unstable OCF, 2 patients presented with an Anderson–Montesano type III and Tuli type IIB injury, while 1 patient had an Anderson–Montesano type I fracture (Tuli type IIB) accompanied by a C1 fracture. On admission, the children underwent computed tomography (CT) of the head and cervical spine as well as magnetic resonance imaging (MRI) of the cervical spine. We treated the children diagnosed with unstable OCF with halo-vest immobilization. Before removing the halo vest at the end of therapy, we applied the CT and MRI to confirm OCF consolidation. At follow-up, we rated functionality of the craniocervical junction (CCJ) based on the Neck Disability Index (NDI) and Questionnaire Short Form 36 Health Survey (SF-36). Results: All children achieved OCF consolidation after halo-vest therapy for a median of 13.0 weeks (range: 12.5–14.0 weeks). CT and MRI at the end of halo-vest therapy showed no signs of C0/C1 subluxation and confirmed the correct consolidation of OCF. The only complication associated with halo-vest therapy was a superficial infection caused by a halo-vest pin. At follow-up, all children exhibited favorable functionality of the CCJ as documented by the NDI score (median: 3 points; range: 3–11 points) and SF-36 score (median: 91 points; range: 64–96 points). Conclusions: In our small case series, halo-vest therapy resulted in good mid-term outcome in terms of OCF consolidation and CCJ functionality. In pediatric patients with suspected cervical spine injuries, we recommend CT and MRI of the CCJ to establish the diagnosis of OCF and confirm stable fracture consolidation before removing the halo vest
The Non-Affected Muscle Volume Compensates for the Partial Loss of Strength after Injection of Botulinum Toxin A
Local botulinum toxin (BTX-A, Botox®) injection in overactive muscles is a standard treatment in patients with cerebral palsy. The effect is markedly reduced in children above the age of 6 to 7. One possible reason for this is the muscle volume affected by the drug. Nine patients (aged 11.5; 8.7–14.5 years) with cerebral palsy GMFCS I were treated with BTX-A for equinus gait at the gastrocnemii and soleus muscles. BTX-A was administered at one or two injection sites per muscle belly and with a maximum of 50 U per injection site. Physical examination, instrumented gait analysis, and musculoskeletal modelling were used to assess standard muscle parameters, kinematics, and kinetics during gait. Magnetic resonance imaging (MRI) was used to detect the affected muscle volume. All the measurements were carried out pre-, 6 weeks post-, and 12 weeks post-BTX-A. Between 9 and 15% of the muscle volume was affected by BTX-A. There was no effect on gait kinematics and kinetics after BTX-A injection, indicating that the overall kinetic demand placed on the plantar flexor muscles remained unchanged. BTX-A is an effective drug for inducing muscle weakness. However, in our patient cohort, the volume of the affected muscle section was limited, and the remaining non-affected parts were able to compensate for the weakened part of the muscle by taking over the kinetic demands associated with gait, thus not enabling a net functional effect in older children. We recommend distributing the drug over the whole muscle belly through multiple injection sites
Erratum to: Poor outcome at 7.5years after Stanisavljevic quadriceps transposition for patello-femoral instability
Introduction: Congenital dislocation of the patella and recurrent symptomatic dislocation in adolescents are difficult pathologies to treat. Stanisavljevic described an extensive release procedure essentially involving medializing the entire lateral quadriceps and medial soft tissue stabilization. There are no significant series reporting the success of this method. This procedure has been performed in our institution over several years and we report our results. Method: Retrospective case series. Between 1990 and 2007, 20 knees in 13 children and adolescents (mean age 12.8years; 4-17, 7 female) with recurrent or congenital dislocation of the patella (8 knees) underwent this procedure after failed conservative treatment (mean follow-up 7.5years; 4-16). All were immobilized in a long leg cast for 6weeks. Results: Five knees in five patients (20%, 1 congenital dislocation) reported their knees as improved without further dislocations. Out of the 15 knees with failures (80%) 12 in six patients (60%) were revised due to redislocation. Three knees in two patients (15%) still had dislocations or subluxations, but any revision was refused. Three knees in three patients caused pain and discomfort during daily activity. Redislocation first developed after a mean of 21.3months (4-72) postoperatively. Only one patient had returned to sport at the 12-month follow-up. Discussion: The Stanisavljevic procedure produces a mediocre success rate with our long-term follow-up series showing a failure rate up to 80%. We therefore recommend more specific procedures dealing with the anatomical deformity such as trochleaplasty to produce superior success rates
Needs and Research Priorities for Young People with Spinal Cord Lesion or Spina Bifida and Their Caregivers: A National Survey in Switzerland within the PEPSCI Collaboration.
The aim of this study was to describe the needs and research priorities of Swiss children/adolescents and young adults (from here, "young people") with spinal cord injury/disorder (SCI/D) or spina bifida (SB) and their parents in the health and life domains as part of the international Pan-European Pediatric Spinal Cord Injury (PEPSCI) collaboration. Surveys included queries about the satisfaction, importance, research priorities, quality of life (QoL), and characteristics of the young people. Fifty-three surveys with corresponding parent-proxy reports were collected between April and November 2019. The self-report QoL sum scores from young people with SCI/D and SB were 77% and 73%, respectively. Parent-proxy report QoL sum scores were lower, with 70% scores for parents of young people with SCI/D and 64% scores for parents of young people with SB. "Having fun", "relation to family members", and "physical functioning" were found to be highly important for all young people. "Physical functioning", "prevention of pressure injuries", "general health", and "bowel management" received the highest scores for research priority in at least one of the subgroups. As parents tend to underestimate the QoL of their children and young people prioritized research topics differently, both young peoples' and caregivers' perspectives should be included in the selection of research topics
Assessment of foot alignment and function for ambulatory children with cerebral palsy: Results of a modified Delphi technique consensus study
PURPOSE
The purpose of this study was to establish consensus for the assessment of foot alignment and function in ambulatory children with cerebral palsy, using expert surgeon's opinion through a modified Delphi technique.
METHODS
The panel used a five-level Likert-type scale to record agreement or disagreement with 33 statements regarding the assessment of foot alignment and function. Consensus was defined as at least 80% of responses being in the highest or lowest of two of the five Likert-type ratings. General agreement was defined as 60%-79% falling into the highest or lowest two ratings. There was no agreement if neither threshold was reached.
RESULTS
Consensus was achieved for 25 (76%) statements, general agreement for 4 (12%) statements, and lack of consensus for 4 (12%) of the statements. There was consensus that the functional anatomy of the foot is best understood by dividing the foot into three segments and two columns. Consensus was achieved concerning descriptors of foot segmental alignment for both static and dynamic assessment. There was consensus that radiographs of the foot should be weight-bearing. There was general agreement that foot deformity in children with cerebral palsy can be classified into three levels based on soft tissue imbalance and skeletal malalignment.
CONCLUSION
The practices identified in this study can be used to establish best care guidelines, and the format used will be a template for future Delphi technique studies on clinical decision-making for the management of specific foot segmental malalignment patterns commonly seen in children with cerebral palsy.

Distal femoral extension osteotomy and patellar tendon advancement or shortening in ambulatory children with cerebral palsy: A modified Delphi consensus study and literature review
PURPOSE
In children with cerebral palsy, flexion deformities of the knee can be treated with a distal femoral extension osteotomy combined with either patellar tendon advancement or patellar tendon shortening. The purpose of this study was to establish a consensus through expert orthopedic opinion, using a modified Delphi process to describe the surgical indications for distal femoral extension osteotomy and patellar tendon advancement/patellar tendon shortening. A literature review was also conducted to summarize the recent literature on distal femoral extension osteotomy and patellar tendon shortening/patellar tendon advancement.
METHOD
A group of 16 pediatric orthopedic surgeons, with more than 10 years of experience in the surgical management of children with cerebral palsy, was established. The group used a 5-level Likert-type scale to record agreement or disagreement with statements regarding distal femoral extension osteotomy and patellar tendon advancement/patellar tendon shortening. Consensus for the surgical indications for distal femoral extension osteotomy and patellar tendon advancement/patellar tendon shortening was achieved through a modified Delphi process. The literature review, summarized studies of clinical outcomes of distal femoral extension osteotomy/patellar tendon shortening/patellar tendon advancement, published between 2008 and 2022.
RESULTS
There was a high level of agreement with consensus for 31 out of 44 (70%) statements on distal femoral extension osteotomy. Agreement was lower for patellar tendon advancement/patellar tendon shortening with consensus reached for 8 of 21 (38%) of statements. The literature review included 25 studies which revealed variation in operative technique for distal femoral extension osteotomy, patellar tendon advancement, and patellar tendon shortening. Distal femoral extension osteotomy and patellar tendon advancement/patellar tendon shortening were generally effective in correcting knee flexion deformities and extensor lag, but there was marked variation in outcomes and complication rates.
CONCLUSION
The results from this study will provide guidelines for surgeons who care for children with cerebral palsy and point to unresolved questions for further research.
