A rare complication of a rare pediatric injury: Transient drop foot following a floating knee injury.

Floating Knee is a rare injury caused by high velocity, and has rarely been described in children. The purpose of this report is to present a case of a six-year-old female after a fall down three and a half flights of stairs, suffering from this rare injury and a rare complication, and her rehabilitation. She suffered fractures of the femur and tibia (Floating Knee type), and was operated on the day of the injury with closed reduction and internal fixation (CRIF). Following the operation, painful drop-foot was evident, related to the fractured bone pressure on the sciatic nerve and a very high level of anxiety. The patient was transferred to a rehabilitation hospital, where she received a total of about 350 physical therapy, hydrotherapy, psychology and occupational therapy treatments over a period of one year. Treatment also consisted of an ankle-foot orthosis (AFO) and transcutaneous electrical stimulation, and were assisted with examinations at the motion analysis laboratory using surface electromyography. The combined orthopedic and physical therapy treatment, and cooperation with psychology in the intervention and training for the care team, enabled achievement of all rehabilitation goals. The patient returned to a high functional level and full participation in daily life activities with her peers, without the need for the AFO or further treatment in the community. A re-examination after about six months showed continued functional improvement according to objective indicators. This case raises awareness of rare injuries and complications in pediatric orthopedic patients, that require multidisciplinary rehabilitation treatment and cooperation between the surgical and rehabilitation teams. Closed injury of the sciatic nerve can be followed for a long period without additional invasive studies or formal nerve exploration, and complete recovery can be achieved.

Hydrotherapy for Patients With External Fixation: Effect on Infectious Events.

BACKGROUND: Surgery to achieve long bone lengthening and deformity correction in skeletally immature patients is traditionally performed through external fixators. The incidence of infection during treatment is high. Hydrotherapy is highly beneficial during external fixation management, but the infection rates may impact its utilization. The objective of this paper is to document the incidence and duration of infection in patients who participated in a full hydrotherapy program when performed under medical supervision and in accordance with strict follow-up protocols. METHODS: In this retrospective study, we documented the key characteristics of patients who participated in hydrotherapy after lower limb external fixation surgery including age, sex, diagnosis and surgery site, the incidence and duration of pin site infections, and the percentage of cases, which were able to comply with a full hydrotherapy protocol. RESULTS: The hydrotherapy pool met all daily water quality metrics. Thirty-four children (19 males and 15 females) had a mean±SD age of 10.9±4.6 years. Of the cases, 80% were unilateral and 20% were bilateral. Diagnoses included congenital hereditary (eg, achondroplasia), congenital nonhereditary conditions (eg, fibular hemimelia), and acquired conditions (eg, traumatic). The location of osteotomy site was quite evenly spread between the femur and the tibia/fibula. Three out of the 34 patients were unable to receive hydrotherapy due to continuous secretions; 2 patients did not miss any sessions. The mean number of treatments was 3 per week. During the entire period, a total of 1200 treatments were performed for these patients with only 32 cancellations (about 3%) due to secretions or other signs of infection. Spearman correlation coefficients showed significantly high correlations between the duration of external fixation and the duration of hydrotherapy. There are no significant correlations between infections and other factors (sex, age segment, whether the problem is unilateral or /bilateral, diagnosis, and duration of treatment). CONCLUSIONS: This is the first report, to our knowledge, that documents the low prevalence of infectious events during hydrotherapy treatment and demonstrates its feasibility. LEVEL OF EVIDENCE: Level III; retrospective, comparative study.

Measuring the knowledge of juvenile idiopathic arthritis among Israeli paediatricians and paediatric orthopaedic surgeons: what needs to be improved?

OBJECTIVES: Approximately 1 child in 1,000 is affected by juvenile idiopathic arthritis (JIA). Persistent, undiagnosed JIA with high disease activity interferes with daily life and carries a risk of irreversible physical and psychosocial damage. Due to its relative rarity, primary care physicians often do not recognise it. Consequently, diagnosis and referral to paediatric rheumatologists are delayed. We aimed to evaluate the knowledge of Israeli paediatricians and paediatric orthopaedic surgeons regarding the epidemiology, clinical manifestations, laboratory parameters and treatment of JIA. METHODS: An 11-item, online questionnaire regarding JIA was sent to Israeli paediatricians and paediatric orthopaedic surgeons. The questionnaire was completed by 318 paediatricians and 30 paediatric orthopaedic surgeons (total response rate 22.5%). RESULTS: The average score was 67/100 points and the pass rate was 70.1% (set at 60 points). Several factors were associated with better overall scores: paediatric residents compared to senior physicians, exposure to rheumatology during residency, and seeing more patients with JIA in the past 5 years. No significant difference was found between paediatricians and paediatric orthopaedic surgeons. The true incidence of JIA was underestimated by 40% of participants, 30-45% were not familiar with its clinical presentation (age of onset, pain characteristics, chronic uveitis symptoms), and 60% were not familiar with up-to-date treatments. CONCLUSIONS: Paediatricians and paediatric orthopaedic surgeons in Israel have gaps in knowledge regarding JIA. This could result in delayed referral and treatment, which might affect outcomes. The results of this study highlight the need for better education and exposure to a rheumatologist, to improve knowledge and recognition of JIA.

The correlation between rhythm perception and gait characteristics at different rhythms among children with cerebral palsy and typically developing children.

BACKGROUND: It has been shown that motor training while listening to constant rhythm, is associated with coupling between movement and rhythm. To gain a better understanding of how rhythm perception may affect gait in children with cerebral palsy (CP) it seems important first to assess rhythm perception (RP) in these children. RESEARCH QUESTION: To describe and compare RP and step characteristics in children with CP and typically-developing (TD) children, and to assess the impact of RP on step characteristics during different rhythms. METHODS: The study included 24 children with CP, Gross Motor Function Classification System (GMFCS) levels I-II, age 7-12 years, who walk without assistive device, and 24 TD children matched for age and gender. RP was assessed by the perceptual beat alignment test (BAT). Gait parameters were recorded using a pressure-sensitive mat - the Gaitrite® system. Each participant walked on the mat at a comfortable walking pace and with the metronome set at 92.5 %, 100 % and 107.5 % of his preferred walking rhythm. RESULTS: No significant difference in RP was noted between groups. Children with CP presented significantly larger step time and length variability. In TD children, those with better RP walked significantly slower, with lower step variability as compared to TD children with lower RP. Children in both groups, regardless of rhythm perception, successfully matched their cadence to the metronome's pace, both at the lower and higher rhythm, except TD children with lower rhythm perception, who failed to reduce their cadence sufficiently in the 92.5 % pace. Children with better RP in both groups changed more parameters in gait in response to rhythm changes. SIGNIFICANCE: Assessing RP may predict which parameters of gait are expected to change when employing a metronome during child's walk.

The impact of breathing rate on the cardiac autonomic dynamics among children with cerebral palsy compared to typically developed controls.

PURPOSE: To describe the immediate effect of breathing rate on heart rate (HR) and heart rate variability (HRV) in children with cerebral palsy (CP) and a control group of typically developed (TD) age and gender-matched children. METHODS: Twenty children with CP at gross motor function classification system levels I-III and 20 TD children aged 6-11 participated in the study. HR was monitored at rest and during paced breathing with biofeedback. Respiratory measures were assessed by KoKo spirometry. RESULTS: Children with CP have lower spirometry and HRV values at rest compared to TD children. The mean reduction of breathing rate during paced breathing among children with CP was significantly smaller. Nonetheless, while practicing paced breathing, both groups reduced their breathing rate and increased their HRV. CONCLUSIONS: The results of the current work present the immediate effect of paced breathing on HRV parameters in CP and TD children. Further studies are needed to investigate the effect of long-term treatment focusing on paced breathing for children with CP.

Treatment of the Lower Extremity Contracture/Deformities.

Lower extremity deformities of patients with arthrogryposis multiplex congenita present a wide spectrum of severity and deformity combinations. Treatment goals range from merely ensuring comfortable seating and shoe wear, to fully independent and active ambulation, but the overarching intention is to help realize the patient's greatest potential for independence and function. Treatment of hip and knee contractures and dislocations has become more interventional, whereas treatment of foot deformities has paradoxically become much less surgical. This article synopsizes the treatment strategies presented in September 2014 in Saint Petersburg, Russia at the second international symposium on arthrogryposis.

Cardiac Autonomic System Response to Submaximal Test in Children With Cerebral Palsy.

AIM: To describe the heart rate (HR) and heart rate variability at rest, during a submaximal treadmill test and at rest posttreadmill in children with cerebral palsy (CP). METHODS: Twenty children (6-11 years) with CP participated, who had Gross Motor Function Classification System levels I to III. The HR was monitored for 5 minutes seated, during a submaximal treadmill test, and after 5 minutes rest posttreadmill. Outcome variables were HR and the square root of the mean squared differences of successive differences between adjacent heart beats (RMSSD). RESULTS: HR increased during the last stage of the treadmill test compared with rest. RMSSD was reduced during the last 2 minutes of the treadmill test compared with rest. The HR and RMSSD mean value at the second minute posttest were not significantly different from the pretreadmill rest value. INTERPRETATION: The cardiac system in children with CP responded to the submaximal testing.

Nemaline body myopathy caused by a novel mutation in troponin T1 (TNNT1).

INTRODUCTION: Nemaline myopathy is a rare disorder characterized by skeletal muscle weakness of varying severity and onset, with the presence of nemaline rods on muscle biopsy. Congenital nemaline body myopathy due to mutations in TNNT1 has hitherto only been described as a result of a single founder mutation in patients of Amish origin and in 2 other individuals with different recessive mutations. METHODS: Autozygosity mapping and whole exome sequencing were applied after we identified 9 Palestinian patients from 7 unrelated families who have nemaline myopathy. RESULTS: All patients were homozygous for a novel complex rearrangement of the TNNT1 gene (c.574_577delinsTAGTGCTGT | NM_003283) leading to C-terminal truncation of the protein (p.L203* | NP_003274.3). Their clinical course was remarkable for early respiratory failure and striking stiffness of the cervical spine. CONCLUSIONS: This report exemplifies the utility of combining autozygosity mapping and whole exome sequencing and expands the phenotype associated with TNNT1 mutations.

Hand surgery for dystrophic epidermolysis bullosa.

BACKGROUND: Epidermolysis bullosa (EB) is a group of inherited, mechanobullous disorders caused by mutations in various structural proteins in the skin. The manifestation of these disorders in the hand is of digital contractures and pseudosyndactyly or "cocoon hands," causing significant functional impairment.Our preferred surgical treatment of these patients involves separation of the digits from the palm by releasing the finger flexion contractures and separating them, primarily the adducted thumb. However, recurrence is common. Our hypothesis was that functional improvement is gained irrespective of recurrence of contractures. METHODS: We retrospectively evaluated 4 patients, 2 male and 2 female, whose average age was 11 years, treated surgically by the separation of all their digits and by coverage with skin grafts. The follow-up period was between 1 and 3½ years. RESULTS: Partial recurrence of the deformity was observed in all patients. Recurrence was more pronounced in the nondominant hand, especially between the digits and of flexion contractures, but did not preclude the use of precision or oppositional pinch at final follow-up. The patient with the longest follow-up has been referred for revision surgery to gain further release of contractures.Significant rehabilitation goals were achieved in all 4 patients after surgery. After 6 months, both of the younger patients were measured for finger dexterity, which showed lower scores than the norm, although this was felt to be dependent on which daily manual activities they were more familiar with. These tests could not have been performed before surgery. CONCLUSIONS: All patients and families felt the effort was worthy. Separating the thumb and straightening the digits was found to be significant, yet the indication for separating all the digits is debatable. The need for revision surgery, to maintain the digit function, is clear. LEVEL OF EVIDENCE: Level 4, case series.

Factors associated with the success of the Rigo System Chêneau brace in treating mild to moderate adolescent idiopathic scoliosis.

BACKGROUND: Adolescent idiopathic scoliosis (AIS) is the most prevalent spine deformity within the pediatric population. Orthosis is the mainstay of conservative treatment for mild to moderate AIS. The Rigo System Chêneau (RSC) brace is a custom-made thoracolumbar sacral orthosis (TLSO) based on a three-dimensional correction concept. The purpose of this study was to identify factors that could predict the therapeutic success/failure of the RSC brace. MATERIALS AND METHODS: A retrospective cohort study was performed on all consecutive patients according to the Scoliosis Research Society (SRS) criteria for the success of conservative treatment. Participants had a 2-year follow-up beyond the termination of brace treatment. All patients were treated with the RSC orthotic device. RESULTS: Ninety-three patients met the inclusion criteria. At treatment onset, their average age was 12.9 years, average Cobb angle 31.97°, Risser score 1.07, and the mean angle of thoracic rotation (ATR) was 10.2°. The mean brace treatment period was 36 months. Treatment was successful in 83.8 % of these patients (n = 79). The average final Cobb angle was 28.97°, Risser score 4.88, and ATR 8.09°. The pre-treatment factors associated with the success of applying the RSC brace were a high Risser score [odds ratio (OR) = 2.97, 95 % confidence interval [CI] 1.18-7.44; p = 0.02), a low Cobb angle (OR = 0.92, 95 % CI 0.85-0.99; p = 0.02), and low ATR (OR = 0.86, 95 % CI 0.75-0.99; p = 0.04). CONCLUSIONS: The treatment of mild to moderate AIS with the RSC brace provides excellent clinical results. Its added benefit is enabling a three-dimensional correction of a three-dimensional deformity. Pre-treatment high Risser score, low Cobb angles, and low ATRs are associated with treatment success. LEVEL OF EVIDENCE: Retrospective analysis, Level III.

Divergent elbow dislocation in the very young child: easily treated if correctly diagnosed.

We report a case of a 3-year-old boy that sustained a divergent elbow dislocation and was treated appropriately once the diagnosis was established. The purpose of this report is to bring attention to this rare injury.

Outcome of Ilizarov ankle arthrodesis.

BACKGROUND: Many operative techniques have been described for ankle arthrodesis, with varying fusion rates. In revisions, the fusion rate is lower than in primary arthrodesis. Recent reports have described good results after Ilizarov ankle arthrodesis. However, descriptions were qualitative, with none using an accepted score. We describe our experience with this technique and functional outcomes in our patients. METHODS: Seventeen patients (average age 48 years) had primary or revision unilateral ankle arthrodesis using the Ilizarov technique at two centers. Diagnoses included post-traumatic arthritis and Charcot arthropathy. Three patients had talar osteonecrosis. Time in the frame averaged 15 weeks and in a cast 4 weeks. Followup averaged 6 years. Outcome was assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. RESULTS: All ankles achieved solid fusion. The average AOFAS score was 65 out of 86 possible. Based on this, results were defined as excellent in three patients, good in eight, fair in four, and poor in two. Minor complications were common, all resolving with local treatment. No deep infection developed. One fusion malunited in 8 degrees of varus. CONCLUSIONS: The Ilizarov external fixator has numerous advantages applicable to ankle fusion, including: stable fixation, respect for soft tissues, and the possibility of postoperative alignment 'fine-tuning'. Additionally, the ability to direct forces through or around skeletal elements allows varying of the load through the skeletal elements, allowing early weightbearing. The Ilizarov technique, with its high union rate, may be considered for any ankle arthrodesis but is especially useful in complex cases such as revisions, talar osteonecrosis, soft-tissue compromise, and infection. Early weightbearing is an added benefit.

Vascular complications of supracondylar humeral fractures in children.

The purpose of this study was to analyze the vascular complications of 24 children with supracondylar humeral fractures treated in two affiliated hospitals and to propose a management plan. Exploration and repair of the brachial artery were undertaken in 11 of the 24 cases in which the pulse did not resume following reduction of the fracture. The repaired vessels were found to be patent on follow-up. Angiography was performed in six of the 24 cases and resulted in improved management in comparison with cases in which no angiography was performed. We believe that intra-operative angiography and vascular repair are indicated in most cases in which a palpable pulse does not resume after fracture reduction.

Femorotibial ankylosis in a child with Roberts syndrome: an "aggressive" approach to habilitation.

INTRODUCTION: Roberts syndrome is a rare autosomal recessive disorder affecting many organs. The marked disabilities are mainly due to extreme short stature and severe limb deformities. Treatment in children who survive focuses on surgical correction of facial and limb defects. CASE DESCRIPTION: Z.B., a 9.5-year-old girl, was diagnosed at birth with Roberts syndrome. She gradually achieved gross and fine motor developmental milestones and spontaneously ambulated by "walking" on her knees. Her primary obstacle to further improvement was the severe fixed flexion deformities of the knees. At age 5 years and 9 months, she underwent surgery which involved quadriceps splitting, exposure, and then excision of the bony ankylosis. Stable fixation was achieved with crossed Kirschner wires. Quadriceps reefing was then performed, and long-leg casts applied. Currently, she walks independently without orthoses and functions as well as her height permits. DISCUSSION: Knee ankylosis is a very rare entity, and the affected patients are usually treated nonoperatively. Careful evaluation and appropriate surgery afforded our patient a better quality of life and should be considered in other patients.

Close reduction and intramedullary flexible titanium nails fixation of femoral shaft fractures in children under 5 years of age.

We retrospectively reviewed 13 cases of diaphyseal femoral fractures treated with close reduction and intramedullary flexible titanium nails, in children aged 3-5 years. The mean follow-up time was 11.5 months (range 3-29). No cases of nonunion or malunion were noted. Minor complications were observed in two children. Loss of initially restored femoral lengthening had occurred in one child, with nail protrusion and related focal cellulites. Mild postoperative leg-length discrepancy occurred in another child. The healed fractures usually exhibited abundant callus, which allowed an early ambulation. Although the operative approach to simple diaphyseal fractures of the femur at such a young age is not routinely recommended, it can be a valuable option as an initial treatment, or when a conventional treatment with a spica cast has failed. In our group of patients, the parents chose this type of treatment as an alternative to the conventional spica cast.

[Arrow injury to the elbow causing arthritis].

We describe a severe injury caused by children's games. During a children's game, a 13 years-old girl was injured by an arrow with a metallic head and suffered injury to the elbow joint necessitating surgical drainage of an inflammatory reaction. This article enhances other descriptions in the literature of body injuries caused by dangerous games, and aims to draw attention to this phenomenon.

Preoperative cardiac events in elderly patients with hip fracture randomized to epidural or conventional analgesia.

BACKGROUND: Perioperative myocardial ischemia occurs in 35% of unselected elderly patients undergoing hip fracture surgery. Perioperative epidural analgesia may reduce the incidence of adverse cardiac events. METHODS: The effect of early administration of epidural analgesia during the stressful period, on cardiac events was evaluated in a prospective randomized study in 68 patients with hip fractures who either had known coronary artery disease or were at high risk for coronary artery disease. On admission to the emergency room, patients were assigned to receive a usual care analgesic regimen (intramuscular meperidine, control group, n = 34) or continuous epidural infusion of local anesthetic and opioid (epidural group, n = 34). Monitoring in the preoperative period included a preoperative history and physical examination, daily assessment of cardiac adverse events, serial electrocardiograms, cardiac enzymes, and pain scores. RESULTS: Preoperative adverse cardiac events were significantly more prevalent in the control group compared with the epidural group (7 of 34 0 of 34; = 0.01). Adverse cardiac events included fatal myocardial infarction in three, fatal congestive heart failure in one, nonfatal congestive heart failure in one, and new onset atrial fibrillation in two. The incidence of intraoperative and postoperative adverse cardiac events was similar for the two groups. The significant difference between groups in the incidence of preoperative cardiac events prompted interruption of the study after the planned interim analysis. CONCLUSIONS: The authors' data indicate that compared with conventional analgesia, early administration of continuous epidural analgesia is associated with a lower incidence of preoperative adverse cardiac events in elderly patients with hip fracture who have or are at risk for coronary artery disease. Preoperative epidural analgesia may be advantageous for this surgical population.
