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.

A retrospective study was performed in 100 children aged between two and 16 years, with a dorsally angulated stable fracture of the distal radius or forearm, who were treated with manipulation in the emergency department (ED) using intranasal diamorphine and 50% oxygen and nitrous oxide. Pre- and post-manipulation radiographs, the final radiographs and the clinical notes were reviewed. A successful reduction was achieved in 90 fractures (90%) and only three children (3%) required remanipulation and Kirschner wire fixation or internal fixation.

The use of Entonox and intranasal diamorphine is safe and effective for the closed reduction of a stable paediatric fracture of the distal radius and forearm in the ED.

By facilitating discharge on the same day, there is a substantial cost benefit to families and the NHS and we recommend this method.

Take home message: Simple easily reducible fractures of the distal radius and forearm in children can be successfully and safely treated in the ED using this approach, thus avoiding theatre admission and costly hospital stay.

Aims. Management of displaced paediatric supracondylar elbow fractures remains widely debated and actual practice is unclear. This national trainee collaboration aimed to evaluate surgical and postoperative management of these injuries across the UK. Methods. This study was led by the South West Orthopaedic Research Division (SWORD) and performed by the Supra Man Collaborative. Displaced paediatric supracondylar elbow fractures undergoing surgery between 1 January 2019 and 31 December 2019 were retrospectively identified and their anonymized data were collected via Research Electronic Data Capture (REDCap). Results. A total of 972 patients were identified across 41 hospitals. Mean age at injury was 6.3 years (1 to 15), 504 were male (52%), 583 involved the left side (60%), and 538 were Gartland type 3 fractures (55%). Median time from injury to theatre was 16 hours (interquartile range (IQR) 6.6 to 22), 300 patients (31%) underwent surgery on the day of injury, and 91 (9%) underwent surgery between 10:00 pm and 8:00 am. Overall, 910 patients (94%) had Kirschner (K)-wire) fixation and these were left percutaneous in 869 (95%), while 62 patients (6%) had manipulation under anaesthetic (MUA) and casting. Crossed K-wire configuration was used as fixation in 544 cases (59.5%). Overall, 208 of the fixation cases (61%) performed or supervised by a paediatric orthopaedic consultant underwent lateral-only fixation, whereas 153 (27%) of the fixation cases performed or supervised by a non-paediatric orthopaedic consultant used lateral-only fixation. In total, 129 percutaneous wires (16%) were removed in theatre. Of the 341 percutaneous wire fixations performed or supervised by a paediatric orthopaedic consultant, 11 (3%) underwent wire removal in theatre, whereas 118 (22%) of the 528 percutaneous wire fixation cases performed or supervised by a non-paediatric orthopaedic consultant underwent wire removal in theatre. Four MUA patients (6%) and seven K-wire fixation patients (0.8%) required revision surgery within 30 days for displacement. Conclusion. The treatment of supracondylar elbow fractures in children varies across the UK. Patient cases where a paediatric orthopaedic consultant was involved had an increased tendency for lateral only K-wire fixation and for wire removal in clinic. Low rates of displacement requiring revision surgery were identified in all fixation configurations. Cite this article: Bone Joint J 2023;105-B(1):82–87

We have modified the Ponseti casting technique by using a below-knee Softcast instead of an above-knee plaster of Paris cast. Treatment was initiated as soon as possible after birth and the Pirani score was recorded at each visit. Following the manipulation techniques of Ponseti, a below-knee Softcast was applied directly over a stockinette for a snug fit and particular attention was paid to creating a deep groove above the heel to prevent slippage. If necessary, a percutaneous Achilles tenotomy was performed and casting continued until the child was fitted with Denis Browne abduction boots. Between April 2003 and May 2007 we treated 51 consecutive babies with 80 idiopathic club feet with a mean age at presentation of 4.5 weeks (4 days to 62 weeks). The initial mean Pirani score was 5.5 (3 to 6). It took a mean of 8.5 weeks (4 to 53) of weekly manipulation and casting to reach the stage of percutaneous Achilles tenotomy. A total of 20 feet (25%) did not require a tenotomy and for the 60 that did, the mean Pirani score at time of operation was 2.5 (0.5 to 3). Denis Browne boots were applied at a mean of 10 weeks (4 to 56) after presentation. The mean time from tenotomy to boots was 3.3 weeks (2 to 10). We experienced one case of cast-slippage during a period of non-attendance, which prolonged the casting process. One case of prolonged casting required repeated tenotomy, and three feet required repeated tenotomy and casting after relapsing while in Denis Browne boots. We believe the use of a below-knee Softcast in conjunction with Ponseti manipulation techniques shows promising initial results which are comparable to those using above-knee plaster of Paris casts

Aims. The Ponseti method is an effective evidence-based treatment for clubfoot. It uses gentle manipulation to adjust the position of the foot in serial treatments towards a more physiological position. Casting is used to hold the newly achieved position. At first, the foot resists the new position imposed by the plaster cast, pressing against the cast, but over time the tissues are expected to adapt to the new position and the force decreases. The aim of this study was to test this hypothesis by measuring the forces between a clubfoot and the cast during treatment with the Ponseti method. Patients and Methods. Force measurements were made during the treatment of ten idiopathic clubfeet. The mean age of the patients was seven days (2 to 30); there were nine boys and one girl. Force data were collected for several weeks at the location of the first metatarsal and the talar neck to determine the adaptation rate of the clubfoot. Results. In all measurements, the force decreased over time. The median (interquartile range) half-life time was determined to be at 26 minutes (20 to 53) for the first metatarsal and 22 minutes (9 to 56) for the talar neck, suggesting that the tissues of the clubfoot adapt to the new position within several hours. Conclusion. This is the first study to provide objective force data that support the hypothesis of adaptation of the idiopathic clubfoot to the new position imposed by the cast. We showed that the expected decrease in corrective force over time does indeed exist and adaptation occurs after a relatively short period of time. The rapid reduction in the forces acting on the foot during treatment with the Ponseti method may allow significant reductions in the interval between treatments compared with the generally accepted period of one week

The Ponseti and French taping methods have reduced the incidence of major surgery in congenital idiopathic clubfoot but incur a significant burden of care, including heel-cord tenotomy. We developed a non-operative regime to reduce treatment intensity without affecting outcome. We treated 402 primary idiopathic clubfeet in patients aged < three months who presented between September 1991 and August 2008. Their Harrold and Walker grades were 6.0% mild, 25.6% moderate and 68.4% severe. All underwent a dynamic outpatient taping regime over five weeks based on Ponseti manipulation, modified Jones strapping and home exercises. Feet with residual equinus (six feet, 1.5%) or relapse within six months (83 feet, 20.9%) underwent one to three additional tapings. Correction was maintained with below-knee splints, exercises and shoes. The clinical outcome at three years of age (385 feet, 95.8% follow-up) showed that taping alone corrected 357 feet (92.7%, ‘good’). Late relapses or failure of taping required limited posterior release in 20 feet (5.2%, ‘fair’) or posteromedial release in eight feet (2.1%, ‘poor’). The long-term (> 10 years) outcomes in 44 feet (23.8% follow-up) were assessed by the Laaveg–Ponseti method as excellent (23 feet, 52.3%), good (17 feet, 38.6%), fair (three feet, 6.8%) or poor (one foot, 2.3%). These compare favourably with published long-term results of the Ponseti or French methods. This dynamic taping regime is a simple non-operative method that delivers improved medium-term and promising long-term results. Cite this article: Bone Joint J 2013;95-B:271–8

Aims

The aim of this study was to gain an agreement on the management of idiopathic congenital talipes equinovarus (CTEV) up to walking age in order to provide a benchmark for practitioners and guide consistent, high-quality care for children with CTEV.

We performed CT to investigate how treatment may modify the basic skeletal pathology of congenital club foot. Two homogenous groups of patients treated by one of the authors (EI) or under his supervision were studied. The first included 32 patients with 47 club feet reviewed at a mean age of 25 years and treated by manipulation, application of toe-to-groin plaster casts and an extensive posteromedial release. The second included 32 patients with 49 club feet reviewed at a mean age of 19 years and treated by the Ponseti manipulation technique, application of toe-to-groin plaster casts and a limited posterior release. At follow-up the shape of the subtalar, talonavicular and calcaneocuboid joints was found to be altered in many feet in both groups. This did not appear to be influenced significantly by the type of treatment performed. Correction of the heel varus and the increased declination angle of the neck of the talus was better in the club feet of the second group, whereas reduction of the medial subluxation of the navicular was better in the first. There was a marked increase in the external ankle torsion angle in the first group and a moderate increase of this angle in the second group, in which medial subluxation of the cuboid on the anterior apophysis of the calcaneum was always corrected. Equinus was corrected in both groups but three-dimensional CT reconstruction of the whole foot showed that cavus, supination and adduction deformities were corrected much better in the second group

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

We present a method of manipulative reduction, immobilisation and fixation using a U-shaped plaster with the elbow in extension for extension-type supracondylar fractures of the humerus in children. When the elbow is in full extension, both the extensor and the flexor muscles are neutralised during manipulative reduction and the carrying angle can be easily assessed thus preventing cubitus varus, the most common complication. In order to evaluate the efficiency of this method, we compared the clinical results of the new method with those of conventional treatment. In a group of 95 children who sustained an extension-type supracondylar fracture of the humerus, 49 were treated by the new method and 46 by the conventional method, reduction and immobilisation in a plaster slab with the elbow in flexion. Reduction and immobilisation were easily achieved and reliably maintained by one manipulation for all the children treated by the new method. In 12 children treated by the conventional method, the initial reduction failed and in seven secondary displacement of the distal fragment occurred during the period of immobilisation in plaster. All required a second or third manipulation. Of the 46 children, 28 (60.9%) had developed cubitus varus at a mean follow-up of 4.6 years when treated by the conventional method. None of the children treated by the new method developed cubitus varus. The mean score, according to the Hospital for Special Surgery (HSS) elbow scoring system, was 91 points using the new method and 78 with the conventional method. The results were statistically significant with regard to the incidence of cubitus varus and the elbow score (p < 0.01) suggesting that the new method is reliable and gives a satisfactory outcome

Aims

The most important complication of treatment of developmental dysplasia of the hip (DDH) is avascular necrosis (AVN) of the femoral head, which can result in proximal femoral growth disturbances leading to pain, dysfunction, and eventually to early onset osteoarthritis. In this study, we aimed to identify morphological variants in hip joint development that are predictive of a poor outcome.

Aims

We aimed to evaluate the health-related quality of life (HRQoL) in children with supracondylar humeral fractures (SCHFs), who were treated following the recommendations of the Paediatric Comprehensive AO Classification, and to assess if HRQoL was associated with AO fracture classification, or fixation with a lateral external fixator compared with closed reduction and percutaneous pinning (CRPP).

In a prospective, randomised controlled trial, 68 children who had a completely displaced metaphyseal fracture of the distal radius were treated either by manipulation (MUA) and application of an above-elbow cast alone or by the additional insertion of a percutaneous Kirschner (K-) wire. Full radiological follow-up to union was obtained in 65 children and 56 returned for clinical evaluation three months after injury. Maintenance of reduction was significantly better in the K-wire group and fewer follow-up radiographs were required. There was no significant difference in the clinical outcome measured three months after injury. Seven of 33 patients in the MUA group had to undergo a second procedure because of an unacceptable position compared with none of the 35 in the K-wire group (chi-squared test, p < 0.01). One patient in the K-wire group required exploration for recovery of a migrated wire. We conclude that the use of a percutaneous K-wire to augment the reduction of the fracture in children who have a completely displaced metaphyseal fracture of the distal radius is a safe and reliable way of maintaining alignment of the fracture

Aims

Following the introduction of national standards in 2009, most major paediatric trauma is now triaged to specialist units offering combined orthopaedic and plastic surgical expertise. We investigated the management of open tibia fractures at a paediatric trauma centre, primarily reporting the risk of infection and rate of union.

Aims

After the initial correction of congenital talipes equinovarus (CTEV) using the Ponseti method, a subsequent dynamic deformity is often managed by transfer of the tendon of tibialis anterior (TATT) to the lateral cuneiform. Many surgeons believe the lateral cuneiform should be ossified before surgery is undertaken. This study quantifies the ossification process of the lateral cuneiform in children with CTEV between one and three years of age.

Aims

Our aim was to describe the mid-term appearances of the repair process of the Achilles tendon after tenotomy in children with a clubfoot treated using the Ponseti method.

Previous studies have identified clinical and demographic risk factors for recurrence in the treatment of idiopathic clubfoot (congenital talipes equinovarus). Evertor muscle activity is not usually considered amongst them. This study aimed to evaluate whether recurrence could be predicted by demographic, clinical and gait parameters. From a series of 103 children with clubfeet, 67 had completed a follow-up of two years: 41 male and 26 female, 38 with idiopathic and 29 with non-idiopathic deformities. The mean age was 3.2 years (2.1 to 6.3). Primary correction was obtained in all 38 children (100%) with an idiopathic deformity, and in 26 of 29 patients (90%) with a non-idiopathic deformity. Overall, 60 children (90%) complied with the abduction brace regime. At a mean follow-up of 31.4 months (24 to 62), recurrence was noted in six children (15.8%) in the idiopathic and 14 children (48.3%) in the non-idiopathic group. Significant correlation was found between poor evertor activity and recurrence in both groups. No statistically significant relationship was found between the rate of recurrence and the severity of the initial deformity, the age at the time of treatment, the number of casts required or the compliance with the brace.

After correction of idiopathic and non-idiopathic clubfoot using the Ponseti method, only poor evertor muscle activity was statistically associated with recurrence. The identification of risk factors for recurrent deformity allows clinicians to anticipate problems and advocate early additional treatment to improve muscle balance around the ankle.

We undertook a retrospective analysis of 306 procedures on 233 patients, with a mean age of 12 years (1 to 21), in order to evaluate the use of somatosensory evoked potential (SSEP) monitoring for the early detection of nerve compromise during external fixation procedures for limb lengthening and correction of deformity. Significant SSEP changes were identified during 58 procedures (19%). In 32 instances (10.5%) the changes were transient, and resolved once the surgical cause had been removed. The remaining 26 (8.5%) were analysed in two groups, depending on whether or not corrective action had been performed in response to critical changes in the SSEP recordings. In 16 cases in which no corrective action was taken, 13 (81.2%, 4.2% overall) developed a post-operative neurological deficit, six of which were permanent and seven temporary, persisting for five to 18 months. In the ten procedures in which corrective action was taken, four patients (40%, 1.3% overall) had a temporary (one to eight months) post-operative neuropathy and six had no deficit.

After appropriate intervention in response to SSEP changes, the incidence and severity of neurological deficits were significantly reduced, with no cases of permanent neuropathy. SSEP monitoring showed 100% sensitivity and 91% specificity for the detection of nerve injury during external fixation. It is an excellent diagnostic technique for identifying nerve lesions when they are still highly reversible.

Supracondylar humeral fractures are common in children, but there are no classification systems or radiological parameters that predict the likelihood of having to perform an open reduction. In a retrospective case–control study we evaluated the use of the medial spike angle and fracture tip–skin distance to predict the mode of reduction (closed or open) and the operating time in fractures with posterolateral displacement. A total of 21 patients (4.35%) with a small medial spike angle (< 45°) were identified from a total of 494 patients, and 42 patients with a medial spike angle of > 45° were randomly selected as controls. The medial spike group had significantly smaller fracture tip–skin distances (p < 0.001), longer operating times (p = 0.004) and more complications (p = 0.033) than the control group. There was no significant difference in the mode of reduction and a composite outcome measure. After adjustments for age and gender, only fracture tip–skin distance remained significantly associated with the operating time (β = -0.724, p = 0.042) and composite outcome (OR 0.863 (95% confidence interval 0.746 to 0.998); p = 0.048).

Paediatric orthopaedic surgeons should have a lower threshold for open reduction when treating patients with a small medial spike angle and a small fracture tip–skin distance.

Children with congenital vertical talus (CVT) have been treated with extensive soft-tissue releases, with a high rate of complications. Recently, reverse Ponseti-type casting followed by percutaneous reduction and fixation has been described, with excellent results in separate cohorts of children with CVT, of either idiopathic or teratological aetiology. There are currently no studies that compare the outcome in these two types. We present a prospective cohort of 13 children (21 feet) with CVT of both idiopathic and teratological aetiology, in which this technique has been used. Clinical, radiological and parent-reported outcomes were obtained at a mean follow-up of 36 months (8 to 57). Six children (nine feet) had associated neuromuscular conditions or syndromes; the condition was idiopathic in seven children (12 feet).

Initial correction was achieved in all children, with significant improvement in all radiological parameters. Recurrence was seen in ten feet. Modification of the technique to include limited capsulotomy at the initial operation may reduce the risk of recurrence.

The reverse Ponseti-type technique is effective in the initial correction of CVT of both idiopathic and teratological aetiology. Recurrence is a problem in both these groups, with higher rates than first reported in the original paper. However, these rates are less than those reported after open surgical release.
