This exploratory randomized controlled trial (RCT) aimed to determine the splint-related outcomes when using the novel biodegradable wood-composite splint (Woodcast) compared to standard synthetic fibreglass (Dynacast) for the immobilization of undisplaced upper limb fractures in children. An exploratory RCT was performed at a tertiary paediatric referral hospital between 1 June 2018 and 30 September 2019. The intention-to-treat population consisted of 170 patients (mean age 8.42 years (SD 3.42); Woodcast (WCG), n = 84, 57 male (67.9%); Dynacast (DNG), n = 86, 58 male (67.4%)). Patients with undisplaced upper limb fractures were randomly assigned to WCG or DNG treatment groups. Primary outcome was the stress stability of the splint material, defined as absence of any deformations or fractures within the splint during study period. Secondary outcomes included patient satisfaction and medical staff opinion. Additionally, biomechanical and chemical analysis of the splint samples was carried out.Aims
Methods
Fractures of the forearm (radius or ulna or both)
in children have traditionally been immobilised in plaster of Paris (POP)
but synthetic cast materials are becoming more popular. There have
been no randomised studies comparing the efficacy of these two materials.
The aim of this study was to investigate which cast material is
superior for the management of these fractures. We undertook a single-centre
prospective randomised trial involving 199 patients with acute fractures
of the forearm requiring general anaesthesia for reduction. Patients
were randomised by sealed envelope into either a POP or synthetic
group and then underwent routine closed reduction and immobilisation
in a cast. The patients were reviewed at one and six weeks. A satisfaction
questionnaire was completed following the removal of the cast. All
clinical complications were recorded and the cast indices were calculated.
There was an increase in complications in the POP group. These complications
included soft areas of POP requiring revision and loss of reduction
with some requiring re-manipulation. There was an increased mean
padding index in the fractures that lost reduction. Synthetic casts
were preferred by the patients. This study indicates that the clinical outcomes and patient satisfaction
are superior using synthetic casts with no reduction in safety. Cite this article:
Two protocols for the operative technique and care of the pin-site with external fixation were compared prospectively. There was a total of 120 patients with 46 in group A and 74 in group B. Infection was defined as an episode of pain or inflammation at a pin site, accompanied by a discharge which was either positive on bacterial culture or responded to a course of antibiotics. Patients in group B had a lower proportion of infected pin sites (p = 0.003) and the time to the first episode of infection was longer (p <
0.001). The risk of pin-site infection is lower if attention is paid to avoiding thermal injury and local formation of haematoma during surgery and if after-care includes the use of an alcoholic antiseptic and occlusive pressure dressings.
We conducted a prospective randomised controlled trial to compare the standard Ponseti plaster method with an accelerated method for the treatment of idiopathic congenital talipes equinovarus. The standard weekly plaster-change method was accelerated to three times per week. We hypothesised that both methods would be equally effective in achieving correction. A total of 40 consecutive patients (61 feet) were entered into the trial. The initial median Pirani score was 5.5 (95% confidence interval 4.5 to 6.0) in the accelerated group and 5.0 (95% confidence interval 4.0 to 5.0) in the standard control group. The scores decreased by an average 4.5 in the accelerated group and 4.0 in the control group. There was no significant difference in the final Pirani score between the two groups (chi-squared test, p = 0.308). The median number of treatment days in plaster was 16 in the accelerated group and 42 in the control group (p <
0.001). Of the 19 patients in the accelerated group, three required plaster treatment for more than 21 days and were then assigned to the standard control method. Of the 40 patients, 36 were followed for a minimum of six months. These results suggest that comparable outcomes can be achieved with an accelerated Ponseti method. The ability to complete all necessary manipulations within a three-week period facilitates treatment where patients have to travel long distances.
There is much debate about the nature and extent of deformities in the proximal femur in children with cerebral palsy. Most authorities accept that increased femoral anteversion is common, but its incidence, severity and clinical significance are less clear. Coxa valga is more controversial and many authorities state that it is a radiological artefact rather than a true deformity. We measured femoral anteversion clinically and the neck-shaft angle radiologically in 292 children with cerebral palsy. This represented 78% of a large, population-based cohort of children with cerebral palsy which included all motor types, topographical distributions and functional levels as determined by the gross motor function classification system. The mean femoral neck anteversion was 36.5° (11° to 67.5°) and the mean neck-shaft angle 147.5° (130° to 178°). These were both increased compared with values in normally developing children. The mean femoral neck anteversion was 30.4° (11° to 50°) at gross motor function classification system level I, 35.5° (8° to 65°) at level II and then plateaued at approximately 40.0° (25° to 67.5°) at levels III, IV and V. The mean neck-shaft angle increased in a step-wise manner from 135.9° (130° to 145°) at gross motor function classification system level I to 163.0° (151° to 178°) at level V. The migration percentage increased in a similar pattern and was closely related to femoral deformity. Based on these findings we believe that displacement of the hip in patients with cerebral palsy can be explained mainly by the abnormal shape of the proximal femur, as a result of delayed walking, limited walking or inability to walk. This has clinical implications for the management of hip displacement in children with cerebral palsy.
