We have reviewed the outcome of 134 hips in 96 children with Graf type-III or type-IV dysplasia of the hip on ultrasound examination. We treated 28 affected hips in 22 children with the Craig splint, 43 hips in 30 children with the Pavlik harness, and 26 hips in 16 children with the von Rosen splint. A total of 37 affected hips in 28 children was not splinted. All children were less than three months of age at referral. Those treated with the von Rosen splint had a significantly better ultrasound appearance at 12 to 20 weeks of age and fewer radiological abnormalities than those not splinted or treated with the Pavlik harness. In the von Rosen group no hip required further treatment with an abduction plaster or operation compared with ten in the Pavlik harness group, three in the Craig splint group and eight in the group without splintage. Our results suggest that the von Rosen splint is more likely to improve the outcome of neonatal dysplasia of the hip and a definitive, large-scale randomised trial is therefore indicated

Aims. The study was undertaken to compare the efficacy of Woodcast splints and plaster-of-Paris casts in maintaining correction following sequential manipulation of idiopathic clubfeet. Methods. In this randomized prospective trial, 23 idiopathic clubfeet were immobilized with plaster-of-Paris casts and 23 clubfeet were immobilized with a splint made of Woodcast that encircled only two-thirds the circumference of the limb. The number of casts or splints needed to obtain full correction, the frequency of cast or splint-related complications, and the time taken for application and removal of the casts and splints were compared. Results. The mean number of casts required to obtain full correction of the deformity (Pirani Score 0) was 4.35 (95% confidence interval (CI) 3.74 to 4.95) when plaster-of-Paris was used and 4.87 (95% CI 4.33 to 5.41) when the Woodcast splint was used (p = 0.190). The time required for application and removal of the Woodcast splint were significantly less than that required for application and removal of plaster-of-Paris casts (p < 0.001). Woodcast splint-related complications were not more frequent than plaster-of-Paris cast related complications. Conclusion. Though Woodcast splints covering two-thirds of the circumference of the lower limbs of infants were effective in maintaining the correction of clubfoot deformity during serial manipulation and casting treatment, the superiority of Woodcasts over plaster-of-Paris could not be established.

Aims. The objective of this study was to evaluate the clinical and radiological outcomes of patients younger than six months of age with developmental dysplasia of the hip (DDH) managed by either a Pavlik harness or Tübingen hip flexion splint. Methods. Records of 251 consecutive infants with a mean age of 89 days (SD 47), diagnosed with DDH between January 2015 and December 2018, were retrospectively reviewed. Inclusion criteria for patients with DDH were: younger than 180 days at the time of diagnosis; ultrasound Graf classification of IIc or greater; treatment by Pavlik harness or Tübingen splint; and no prior treatment history. All patients underwent hip ultrasound every seven days during the first three weeks of treatment and subsequently every three to four weeks until completion of treatment. If no signs of improvement were found after three weeks, the Pavlik harness or Tübingen splint was discontinued. Statistical analysis was performed. Results. The study included 251 patients with Graf grades IIc to IV in 18 males and 233 females with DDH. Mean follow-up time was 22 months (SD 10). A total of 116 hips were graded as Graf IIc (39.1%), nine as grade D (3.0%), 100 as grade III (33.7%), and 72 as grade IV (24.2%). There were 109 patients (128 hips) in the Pavlik group and 142 patients (169 hips) in the Tübingen group (p = 0.227). The Tübingen group showed a 69.8% success rate in Graf III and Graf IV hips while the success rate was significantly lower in the Pavlik group, 53.9% (p = 0.033). For infants older than three months of age, the Tübingen group showed a 71.4% success rate, and the Pavlik group a 54.4% success rate (p = 0.047). Conclusion. The Tübingen splint should be the preferred treatment option for children older than three months, and for those with severe forms of DDH such as Graf grade III and IV, who are younger than six months at time of diagnosis. The Tübingen hip flexion splint is a valid alternative to the Pavlik harness for older infants and those with more severe DDH. Cite this article: Bone Joint J 2021;103-B(5):991–998

Aims. It is not clear which type of casting provides the best initial treatment in adults with a distal radial fracture. Given that between 32% and 64% of adequately reduced fractures redisplace during immobilization in a cast, preventing redisplacement and a disabling malunion or secondary surgery is an aim of treatment. In this study, we investigated whether circumferential casting leads to fewer fracture redisplacements and better one-year outcomes compared to plaster splinting. Methods. In a pragmatic, open-label, multicentre, two-period cluster-randomized superiority trial, we compared these two types of casting. Recruitment took place in ten hospitals. Eligible patients aged ≥ 18 years with a displaced distal radial fracture, which was acceptably aligned after closed reduction, were included. The primary outcome measure was the rate of redisplacement within five weeks of immobilization. Secondary outcomes were the rate of complaints relating to the cast, clinical outcomes at three months, patient-reported outcome measures (PROMs) (using the numerical rating scale (NRS), the abbreviated version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Patient-Rated Wrist/Hand Evaluation (PRWHE) scores), and adverse events such as the development of compartment syndrome during one year of follow-up. We used multivariable mixed-effects logistic regression for the analysis of the primary outcome measure. Results. The study included 420 patients. There was no significant difference between the rate of redisplacement of the fracture between the groups: 47% (n = 88) for those treated with a plaster splint and 49% (n = 90) for those treated with a circumferential cast (odds ratio 1.05 (95% confidence interval (CI) 0.65 to 1.70); p = 0.854). Patients treated in a plaster splint reported significantly more pain than those treated with a circumferential cast, during the first week of treatment (estimated mean NRS 4.7 (95% CI 4.3 to 5.1) vs 4.1 (95% CI 3.7 to 4.4); p = 0.014). The rate of complaints relating to the cast, clinical outcomes and PROMs did not differ significantly between the groups (p > 0.05). Compartment syndrome did not occur. Conclusion. Circumferential casting did not result in a significantly different rate of redisplacement of the fracture compared with the use of a plaster splint. There were comparable outcomes in both groups.

Aims. 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. Methods. 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. Results. Of the initial 170 patients, 168 (98.8%) completed at least one follow-up, and were included for analysis of the primary endpoint. Both treatment groups were well-matched regarding to age, sex, and type and localization of the fracture. Splint breakage occurred in three patients (3.6%; 95% confidence interval (CI), 0.007% to 0.102%) in the WCG and in three children (3.5%, 95% CI 0.007% to 0.09%) in the DNG (p > 0.99). The incidence of splint-related adverse events did not differ between the WCG (n = 21; 25.0%) and DNG (n = 24; 27.9%; p = 0.720). Under experimental conditions, the maximal tensile strength of Dynacast samples was higher than those deriving from Woodcast (mean 15.37 N/mm² (SD 1.37) vs 10.75 N/mm² (SD 1.20); p = 0.002). Chemical analysis revealed detection of polyisocyanate-prepolymer in Dynacast and polyester in Woodcast samples. Conclusion. Splint-related adverse events appear similar between WCG and DNG treatment groups during the treatment of undisplaced forearm fractures. Cite this article: Bone Joint J 2020;102-B(10):1405–1411

The Thomas splint is a common piece of equipment in emergency departments and orthopaedic units in hospitals worldwide. Its basic design has changed little since its first description by Hugh Owen Thomas was published in 1875. We have reviewed the origins of the Thomas splint as a means of correction of deformities of the lower limb and its evolution through both World Wars into an essential item for the management of trauma of the lower limb

Between January 1987 and December 1988 there were 7575 births in the Swansea maternity unit. Of these 823 (10.9%) were considered to be at ‘high risk’ for developmental dysplasia of the hip (DDH). Static ultrasound examination was performed in each case and the results classified on the basis of the method of Graf. A total of 117 type III–IV hips in 83 infants was splinted using the Aberdeen splint. Radiographs of these hips were taken at six and 12 months. Hilgenreiner’s measurements of the acetabular angle were made in all cases and the development of the femoral capital epiphysis was assessed by measuring the epiphyseal area. The effect of splintage on the acetabular angle and the epiphyseal area between the normal and abnormal splinted hips was compared. Radiographs of 16 normal infants (32 normal unsplinted hips) were used as a control group. This cohort has now been followed up for a minimum of nine years. There have been no complications as a result of splintage. The failure rate was 1.7% or 0.25 per 1000 live births. No statistical difference was found when comparing the effect of splintage on the acetabular angle and epiphyseal area between normal and abnormal splinted hips and normal unsplinted hips. Our study has shown that while the Aberdeen splint had a definite but small failure rate, it was safe in that it did not produce avascular necrosis. The current conventional view that a low rate of splintage is always best is therefore brought into question if the Aberdeen splint is chosen for the management of neonatal DDH

We have treated 22 patients with an elbow contracture using a static progressive turnbuckle splint for a mean of 4.5 ± 1.8 months. All had failed to improve with supervised physiotherapy and splinting. The mean range of flexion before splintage was from 32 ± 10° to 108 ± 19° and afterwards from 26 ± 10° (p = 0.02) to 127 ± 12° (p = 0.0001). A total of 11 patients gained a ‘functional arc of movement,’ defined as at least 30° to 130°. In eight patients movement improved with turnbuckle splinting, but the functional arc was not achieved. Six of these were satisfied and did not wish to proceed with surgical treatment and two had release of the elbow contracture. In three patients movement did not improve with the use of the turnbuckle splint and one subsequently had surgical treatment. Our findings have shown that turnbuckle splinting is a safe and effective treatment which should be considered in patients whose established elbow contractures have failed to respond to conventional physiotherapy

Aims. A national screening programme has existed in the UK for the diagnosis of developmental dysplasia of the hip (DDH) since 1969. However, every aspect of screening and treatment remains controversial. Screening programmes throughout the world vary enormously, and in the UK there is significant variation in screening practice and treatment pathways. We report the results of an attempt by the British Society for Children’s Orthopaedic Surgery (BSCOS) to identify a nationwide consensus for the management of DDH in order to unify treatment and suggest an approach for screening. Methods. A Delphi consensus study was performed among the membership of BSCOS. Statements were generated by a steering group regarding aspects of the management of DDH in children aged under three months, namely screening and surveillance (15 questions), the technique of ultrasound scanning (eight questions), the initiation of treatment (19 questions), care during treatment with a splint (ten questions), and on quality, governance, and research (eight questions). A two-round Delphi process was used and a consensus document was produced at the final meeting of the steering group. Results. A total of 60 statements were graded by 128 clinicians in the first round and 132 in the second round. Consensus was reached on 30 out of 60 statements in the first round and an additional 12 in the seond. This was summarized in a consensus statement and distilled into a flowchart to guide clinical practice. Conclusion. We identified agreement in an area of medicine that has a long history of controversy and varied practice. None of the areas of consensus are based on high-quality evidence. This document is thus a framework to guide clinical practice and on which high-quality clinical trials can be developed. Cite this article: Bone Joint J 2023;105-B(2):209–214

1. The principle of the vacuum splint is described. 2. A simple, cheap operating splint has been found useful to replace sandbags and other supports. 3. Applications to commonly practised orthopaedic operations are discussed

We treated 91 congenital club feet in 59 children using a modified Denis Browne splint, and followed them for an average of 6 years and 3 months. The modified splint has an aluminium crossbar holding a pair of plastic shoe inserts moulded into corrected positions, and its use was started in children whose ages ranged from four weeks to nine months. Operation was later required in only 31 feet in 20 children. We have reviewed the other 60 feet in 39 children treated by splintage alone. All 60 feet had excellent or good function and from radiographic assessment, equinus, adduction, varus and cavus deformities had all been well corrected. Our results show that the modified splint can give good results

Twenty-two patients with ulnar nerve palsy at the elbow, confirmed by electromyography, were treated by a night splint which prevented flexion of the elbow beyond 60 degrees. The splint was worn all night regularly for at least six months. At a mean follow-up of 11.3 months, 17 patients had clinical and electromyographic assessment and five were contacted by telephone. There was improvement in the symptoms in every patient, including three who had failed to respond to surgical decompression. There was electromyographic improvement in 16 of the 17 patients re-examined at follow-up. The mean improvement in motor nerve conduction velocity was 6.5 m/s and in sensory nerve conduction velocity 9.5 m/s. The efficacy of this treatment suggests that nocturnal elbow flexion is an important cause of ulnar nerve lesions at the elbow

We have assessed the current range of synthetic splinting bandages, using physical and mechanical tests and the subjective opinions of patients, volunteers and orthopaedic staff. Modern bandages have some better properties than standard plaster bandage but do not conform as well, are more expensive, and potentially more hazardous

Forty patients with acute complete rupture of the calcaneal tendon were managed conservatively and randomly allocated to treatment groups using either cast immobilisation for eight weeks, or cast immobilisation for three weeks, followed by controlled early mobilisation in a Sheffield splint. The splint is an ankle-foot orthosis which holds the ankle in 15 degrees of plantar flexion, but allows some movement at the metatarsophalangeal joints. It is removed to allow controlled movement during physiotherapy. Patients treated with the splint regained mobility significantly more quickly (p less than 0.001) and preferred the splint to the plaster cast. The range of dorsiflexion at the ankle improved more rapidly after treatment in the splint (p less than 0.001), and patients were able to return to normal activities sooner. Recovery of the power of plantar flexion was similar in the two treatment groups, and no patient had excessive lengthening of the tendon. One re-rupture occurred in each group

The effect of the position of splintage on displacement of fractures of the waist of the scaphoid was studied during operations and in cadavers. We found that these fractures were best splinted in neutral or slight palmar flexion with no ulnar deviation. Providing the wrist was not ulnar deviated, the position of the thumb had no effect on displacement

1. The records of forty-nine patients with idiopathic structural scoliosis in infancy treated by a combination of splinting and physiotherapy have been reviewed. 2. Nine curves (18·3 per cent) failed to respond to treatment and five of these progressed. 3. The percentage of good results (81·7 per cent) shows no improvement on the natural course of the condition

Aims

The aim of this trial was to assess the cost-effectiveness of a soft bandage and immediate discharge, compared with rigid immobilization, in children aged four to 15 years with a torus fracture of the distal radius.

Avascular necrosis of the scaphoid following a fracture in children is rare and there is no established treatment protocol in the literature. We present two boys with nonunion and avascular necrosis of the scaphoid treated by simple immobilisation. Both cases healed with painless wrists and full movements. Our cases confirm that an ununited scaphoid fracture in children may heal with conservative treatment, even when an MRI scan suggests avascular necrosis. Unlike in adults, operative treatment need only be considered in children when conservative treatment fails.
