Buckling down on torus fractures: has evolving evidence affected practice?

PURPOSE: The purpose of this study was to evaluate the management of paediatric torus fractures of the distal forearm in current practice in light of growing evidence supporting a 'minimalist' approach with splint immobilization and limited follow-up. We hypothesized that 'traditional' cast-based management has persisted despite alternative evidence. METHODS: A retrospective review was performed of a consecutive series of paediatric patients diagnosed with torus fractures of the distal forearm between 2011 and 2014. Records were reviewed to abstract the type of immobilization (splint versus cast) prescribed at each visit, number of radiographic exams, duration of immobilization, number of clinical visits and complications. The primary outcome was the proportion of patients exclusively managed in splints. Injuries were grouped based on treatment into a cast group (CG) and a splint group (SG) for statistical analyses. Additionally, injuries were grouped by epoch of time to determine if immobilization usage patterns evolved. RESULTS: A total of 240 forty injuries met criteria for inclusion. Of these, 16 (6.7%) were exclusively splinted (SG). Relative to the CG, the SG had fewer clinical visits (p < 0.001), fewer radiographic exams (p < 0.001) and a shorter total encounter time (p = 0.015). No change in immobilization use occurred over the study period. In all, 21 (9.4%) of the CG experienced complications. No clinically significant displacements occurred in either group. CONCLUSION: Cast utilization and frequent radiographic follow-up remain prevalent at our institution in the management of paediatric torus fractures. Splint-only management was associated with fewer clinical visits, fewer radiographic exams and a shorter total encounter time. LEVEL OF EVIDENCE LEVEL III: Therapeutic retrospective cohort study.

Submuscular Isola rod with or without limited apical fusion in the management of severe spinal deformities in young children: preliminary report.

STUDY DESIGN: Retrospective review of the results of submuscular rod placement with and without limited apical fusion for the treatment of severe spinal deformities in young children. OBJECTIVES: To determine the success of this method for controlling severe deformities while allowing for spinal growth and to compare this method with previously reported results. SUMMARY OF BACKGROUND DATA: A variety of methods for controlling scoliosis in young children have been reported, but complications including spontaneous fusion, loss of correction, instrumentation failure, and limited spinal growth are common. METHODS: The cases of 29 young children with progressive scoliosis or kyphoscoliosis as a result of a variety of diagnoses treated with a submuscular Isola rod and a postoperative orthosis were retrospectively reviewed. Eleven patients also had a short anterior and posterior apical fusion or convex hemiepiphysiodesis to aid in correction and stabilization of their deformity. The remaining 18 patients had a submuscular rod only. RESULTS: The mean age at surgery was 6.7 years (range, 1-11 years). The initial preoperative mean magnitude of the major curve was 66 degrees (range, 42-112 degrees ). After surgery this decreased to a mean of 38 degrees (range, 16-70 degrees ). The most recent radiographs demonstrated a mean 47 degrees curve (range, 28-79 degrees ). The mean number of lengthenings per patient has been two (range, 0-5). Nine patients have reached a suitable age and have been converted to a posterior spinal fusion and segmental spinal instrumentation. Nine complications have occurred in seven patients (24%). These included five hook displacements and three rod breakages. These were treated by hook reinsertion and rod exchange or sleeve and a repeat lengthening. There was one superficial infection treated medically. CONCLUSION: This technique is useful in the management of severe spinal deformities in young children who have either failed, or have a contraindication to, orthotic management. Complications are relatively frequent but well tolerated.

The Effect of epsilon-aminocaproic acid on perioperative blood loss in patients with idiopathic scoliosis undergoing posterior spinal fusion: a preliminary prospective study.

STUDY DESIGN: A prospective study evaluating the efficacy of epsilon-aminocaproic acid (EACA) in decreasing perioperative blood loss in idiopathic scoliosis. OBJECTIVES: To compare the perioperative blood loss and need for blood replacement in two groups of patients undergoing surgery for idiopathic scoliosis. One group received intraoperative EACA; the other did not and served as controls. SUMMARY OF BACKGROUND DATA: Excessive blood loss increases the operative time, risk for blood product disease transmission, postoperative complications, and costs associated with posterior spinal fusion and instrumentation. EACA is an antifibrinolytic agent that has been shown to be effective in reducing perioperative blood loss during pediatric cardiothoracic surgical procedures. We hypothesized that it would also be effective in lowering blood loss during posterior spinal fusion for idiopathic scoliosis. METHODS: We compared the perioperative blood loss of 28 consecutive pediatric patients with idiopathic scoliosis who underwent posterior spinal fusion and received intraoperative EACA with 31 consecutive patients who did not receive this medication and served as a control group. RESULTS: The patients in both groups were similar. Patients in the EACA group demonstrated statistically significant decreases in total estimated perioperative blood loss and the need for autologous blood transfusion. The patients in the EACA group had no intraoperative or postoperative complications related to the use of this medication. CONCLUSIONS: Based on these preliminary findings, we believe that EACA is helpful in decreasing blood loss in patients undergoing posterior spinal fusion and instrumentation, and may decrease the number of autologous units needed to maintain safe perioperative hemoglobin levels, thereby improving safety and lowering cost associated with scoliosis surgery.

The rigid flatfoot. Tarsal coalitions.

Tarsal coalitions are the major cause of painful rigid flatfoot deformity in children and adolescents. Talocalcaneal and calcaneonavicular coalitions are the most common sites. They are often bilateral and may be asymptomatic. They represent a failure of fetal mesenchymal differentiation, and onset of symptoms in children often corresponds to the time of ossification of the fibrous or cartilaginous coalition. The most common presenting symptom is pain, and diagnosis is aided by plain radiographs and computerized tomography. Some patients respond to conservative measures, but surgical treatment is often required. Resection and interposition of fat or tendon (talocalcaneal) or muscle (calcaneonavicular) are the most common operative treatments, with arthrodesis reserved for symptomatic recurrences, patients with degenerative changes, and those with multiple coalitions.

Compartment syndrome in ipsilateral humerus and forearm fractures in children.

Ipsilateral fractures of the humerus and forearm are uncommon injuries in children. The incidence of compartment syndrome in association with these fractures is controversial. The authors reviewed 978 consecutive children admitted to the hospital with upper extremity long bone fractures during a 13-year period. Forty-three children with ipsilateral fractures of the humerus and forearm were identified. Of 33 children with a supracondylar humerus fracture and ipsilateral forearm fracture, three children (7%) had compartment syndrome develop and required forearm fasciotomies. All three cases of compartment syndrome occurred among nine children with ipsilateral displaced extension supracondylar humerus and displaced forearm fractures; the incidence of compartment syndrome was 33% in this group. These findings suggest that children who sustain a displaced extension supracondylar humerus fracture and displaced forearm fracture are at significant risk for compartment syndrome. These children should be monitored closely during the perioperative period for signs and symptoms of increasing intracompartmental pressures in the forearm.

Role of intentional abuse in children 1 to 5 years old with isolated femoral shaft fractures.

We reviewed 42 children, aged 1-5 years, with isolated femoral shaft fractures to investigate the possible role of intentional injury in these children. Those children with documented motor vehicle accidents or pathologic fractures were excluded. Follow-up from the Department of Social Services regarding the potential for the fractures being inflicted was obtained. The average age of the children was 3.1 +/- 1.2 years; the fracture was spiral in 28. oblique in six, and transverse in eight; history of a fall was present in 34 and absent in eight. The history was considered suspicious for intentional injury in 14 children. In all 42 children, only one fracture was documented to be inflicted; one other child had prior documentation of intentional injury. From this review, the likelihood of intentional injury to the femoral shaft appears to be low; unfortunately, there were no discriminating clinical parameters to help to determine which injuries were intentional. The clinician should continue to have a high index of suspicion and have the circumstances investigated if concern exists regarding the fracture.

The role of melatonin in the pathogenesis of adolescent idiopathic scoliosis.

STUDY DESIGN: A matched, case-control study comparing melatonin production in female patients with and without adolescent idiopathic scoliosis. OBJECTIVES: To determine whether melatonin production is decreased in adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA: A central etiology for idiopathic scoliosis has never been established. Previous authors have produced experimental scoliosis in chickens after pinealectomy, preventable by administration of melatonin. They suggested that a defect in melatonin synthesis might be involved in the pathogenesis of human idiopathic scoliosis. METHODS: Nine female adolescents with no medical problems, normal neurologic examinations, radiographic idiopathic scoliosis of 15-40 degrees, and Risser Stage I-III were in the patient group. Eighteen healthy adolescent girls with no medical problems, a negative school screening, and no family history of scoliosis were control subjects. Patients and control subjects were matched for age, weight, Tanner stage, sleep duration, and light exposure by multiple linear regression. Nighttime and daytime urine samples were analyzed for melatonin by high-performance liquid chromatography. RESULTS: Although nighttime melatonin levels were significantly higher than daytime levels in all volunteers (P < 0.00002), there were no significant differences in nighttime (P > 0.63) or daytime (P > 0.78) melatonin levels between patients and control subjects, even after matching by multiple linear regression analysis. A statistical analysis demonstrated that if a melatonin deficiency of 25% or more did exist in patients with scoliosis compared with control subjects, the likelihood that it would have been detected in this study was more than 98%. CONCLUSION: Although melatonin deficiency may cause scoliosis in the chicken, this study suggests that it is not a mechanism in the pathogenesis of adolescent idiopathic scoliosis in humans.
