Aims. Congenital pseudarthrosis of the tibia (CPT) has traditionally been a difficult condition to treat, with high complication rates, including nonunion, refractures,
Accurate skeletal age and final adult height prediction methods in paediatric orthopaedics are crucial for determining optimal timing of growth-guiding interventions and minimizing complications in treatments of various conditions. This study aimed to evaluate the accuracy of final adult height predictions using the central peak height (CPH) method with long leg X-rays and four different multiplier tables. This study included 31 patients who underwent temporary hemiepiphysiodesis for varus or valgus deformity of the leg between 2014 and 2020. The skeletal age at surgical intervention was evaluated using the CPH method with long leg radiographs. The true final adult height (FHTRUE) was determined when the growth plates were closed. The final height prediction accuracy of four different multiplier tables (1. Bayley and Pinneau; 2. Paley et al; 3. Sanders – Greulich and Pyle (SGP); and 4. Sanders – peak height velocity (PHV)) was then compared using either skeletal age or chronological age.Aims
Methods
Temporary hemiepiphysiodesis (HED) is applied to children and adolescents to correct angular deformities (ADs) in long bones through guided growth. Traditional Blount staples or two-hole plates are mainly used for this indication. Despite precise surgical techniques and attentive postoperative follow-up, implant-associated complications are frequently described. To address these pitfalls, a flexible staple was developed to combine the advantages of the established implants. This study provides the first results of guided growth using the new implant and compares these with the established two-hole plates and Blount staples. Between January 2013 and December 2016, 138 patients (22 children, 116 adolescents) with genu valgum or genu varum were treated with 285 flexible staples. The minimum follow-up was 24 months. These results were compared with 98 patients treated with 205 two-hole plates and 92 patients treated with 535 Blount staples. In long-standing anteroposterior radiographs, mechanical axis deviations (MADs) were measured before and during treatment to analyze treatment efficiency. The evaluation of the new flexible staple was performed according to the idea, development, evaluation, assessment, long-term (IDEAL) study framework (Stage 2a).Aims
Methods
The aim of this retrospective cohort study was to assess and investigate the safety and efficacy of using a distal tibial osteotomy compared to proximal osteotomy for limb lengthening in children. In this study, there were 59 consecutive tibial lengthening and deformity corrections in 57 children using a circular frame. All were performed or supervised by the senior author between January 2013 and June 2019. A total of 25 who underwent a distal tibial osteotomy were analyzed and compared to a group of 34 who had a standard proximal tibial osteotomy. For each patient, the primary diagnosis, time in frame, complications, and lengthening achieved were recorded. From these data, the frame index was calculated (days/cm) and analyzed.Aims
Methods
Temporary epiphysiodesis (ED) is commonly applied in children and adolescents to treat leg length discrepancies (LLDs) and tall stature. Traditional Blount staples or modern two-hole plates are used in clinical practice. However, they require accurate planning, precise surgical techniques, and attentive follow-up to achieve the desired outcome without complications. This study reports the results of ED using a novel rigid staple (RigidTack) incorporating safety, as well as technical and procedural success according to the idea, development, evaluation, assessment, long-term (IDEAL) study framework. A cohort of 56 patients, including 45 unilateral EDs for LLD and 11 bilateral EDs for tall stature, were prospectively analyzed. ED was performed with 222 rigid staples with a mean follow-up of 24.4 months (8 to 49). Patients with a predicted LLD of ≥ 2 cm at skeletal maturity were included. Mean age at surgery was 12.1 years (8 to 14). Correction and complication rates including implant-associated problems, and secondary deformities as well as perioperative parameters, were recorded (IDEAL stage 2a). These results were compared to historical cohorts treated for correction of LLD with two-hole plates or Blount staples.Aims
Methods
The aims of this study is to report the clinical and radiological outcomes after pre-, central-, and postaxial polydactyly resection in children from a tertiary referral centre. All children who underwent resection of a supernumerary toe between 2001 and 2013 were prospectively enrolled and invited for a single re-assessment. Clinical parameters and several dedicated outcome scores (visual analogue scale (VAS), Paediatric Outcomes Data Collection Instrument (PODCI), Activities Scale for Kids (ASK), and American Orthopaedic Foot and Ankle Society Score (AOFAS)) were obtained, as were radiographs of the operated and non-operated feet along with pedobarographs.Aims
Methods
To analyze outcomes reported in trials of childhood fractures. OVID MEDLINE, Embase, and Cochrane CENTRAL databases were searched on the eighth August 2019. A manual search of trial registries, bibliographic review and internet search was used to identify additional studies. 11,476 studies were screened following PRISMA guidelines. 100 trials were included in the analysis. Data extraction was completed by two researchers for each trial. Study quality was not evaluated. Outcomes reported by trials were mapped onto domains in the World Health Organization (WHO) International Classification of Function framework.Aims
Methods
Anterior cruciate ligament (ACL) surgery in children and the adolescent population has increased steadily over recent years. We used a national database to look at trends in ACL reconstruction and rates of serious complications, growth disturbance, and revision surgery, over 20 years. All hospital episodes for patients undergoing ACL reconstruction, under the age of 20 years, between 1 April 1997 and 31 March 2017, were extracted by procedure code from the national Hospital Episode Statistics (HES). Population standardized rates of intervention were determined by age group and year of treatment. Subsequent rates of serious complications including reoperation for infection, growth disturbance (osteotomy, epiphysiodesis), revision reconstruction, and/or contralateral ACL reconstruction rates were determined.Aims

The purpose of this study was to evaluate the long-term outcome
of adolescents with cerebral palsy who have undergone single-event
multilevel surgery for a flexed-knee gait, followed into young adulthood
using 3D motion analysis. A total of 59 young adults with spastic cerebral palsy, with
a mean age of 26 years (Aims
Patients and Methods
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. A retrospective review was performed on 61 children who between
2007 and 2015 presented with an open tibia fracture. Their mean
age was nine years (2 to 16) and the median follow-up was ten months
(interquartile range 5 to 18). Management involved IV antibiotics,
early debridement and combined treatment of the skeletal and soft-tissue injuries
in line with standards proposed by the British Orthopaedic Association.Aims
Patients and Methods
We wished to examine the effectiveness of tibial lengthening
using a two ring Ilizarov frame in skeletally immature patients.
This is a potentially biomechanically unstable construct which risks
the loss of axial control. We retrospectively reviewed a consecutive series of 24 boys and
26 girls, with a mean age of 8.6 years (4 to 14), who underwent
52 tibial lengthening procedures with a mean follow-up of 4.3 years
(4.0 to 16.9). Tibial alignment was measured before and after treatment
using joint orientation lines from the knee and a calculation of
the oblique plane axis.Aims
Patients and Methods
In this study we evaluated the results of midtarsal
release and open reduction for the treatment of children with convex
congenital foot (CCF) (vertical talus) and compared them with the
published results of peritalar release. Between 1977 and 2009, a
total of 22 children (31 feet) underwent this procedure. In 15 children
(48%) the CCF was isolated and in the remainder it was not (seven
with arthrogryposis, two with spinal dysraphism, one with a polymalformative
syndrome and six with an undefined neurological disorder). Pre-operatively, the mean tibiotalar angle was 150.2° (106° to
175°) and the mean calcaneal pitch angle was -19.3° (-72° to 4°).
The procedure included talonavicular and calcaneocuboid joint capsulotomies,
lengthening of tendons of tibialis anterior and the extensors of
the toes, allowing reduction of the midtarsal joints. Lengthening
of the Achilles tendon was necessary in 23 feet (74%). The mean follow-up was 11 years (2 to 21). The results, as assessed
by the Adelaar score, were good in 24 feet (77.4%), fair in six
(19.3%) and poor in one foot (3.3%), with no difference between
those with isolated CCF and those without. The mean American Orthopaedic
Foot and Ankle Society midfoot score was 89.9 (54 to 100) and 77.8
(36 to 93) for those with isolated CCF and those without, respectively.
At the final follow-up, the mean tibiotalar (120°; 90 to 152) and
calcaneal pitch angles (4°; -13 to 22) had improved significantly
(p <
0.0001). Dislocation of the talonavicular and calcaneocuboid
joints was completely reduced in 22 (70.9%) and 29 (93.6%) of feet,
respectively. Three children (five feet) underwent further surgery
at a mean of 8.5 years post-operatively, three with pes planovalgus
and two in whom the deformity had been undercorrected. No child
developed avascular necrosis of the talus. Midtarsal joint release and open reduction is a satisfactory
procedure, which may provide better results than peritalar release.
Complications include the development of pes planovalgus and persistent
dorsal subluxation of the talonavicular joint. Cite this article:
At our institution surgical correction of symptomatic
flat foot deformities in children has been guided by a paradigm in
which radiographs and pedobarography are used in the assessment
of outcome following treatment. Retrospective review of children
with symptomatic flat feet who had undergone surgical correction
was performed to assess the outcome and establish the relationship
between the static alignment and the dynamic loading of the foot. A total of 17 children (21 feet) were assessed before and after
correction of soft-tissue contractures and lateral column lengthening,
using standardised radiological and pedobarographic techniques for
which normative data were available. We found significantly improved static segmental alignment of
the foot, significantly improved mediolateral dimension foot loading,
and worsened fore-aft foot loading, following surgical treatment.
Only four significant associations were found between radiological
measures of static segmental alignment and dynamic loading of the foot. Weakness of the plantar flexors of the ankle was a common post-operative
finding. Surgeons should be judicious in the magnitude of lengthening
of the plantar flexors that is undertaken and use techniques that
minimise subsequent weakening of this muscle group. Cite this article:
Between 2005 and 2010 ten consecutive children
with high-energy open diaphyseal tibial fractures were treated by early
reduction and application of a programmable circular external fixator.
They were all male with a mean age of 11.5 years (5.2 to 15.4),
and they were followed for a mean of 34.5 months (6 to 77). Full
weight-bearing was allowed immediately post-operatively. The mean
time from application to removal of the frame was 16 weeks (12 to
21). The mean deformity following removal of the frame was 0.15°
(0° to 1.5°) of coronal angulation, 0.2° (0° to 2°) sagittal angulation,
1.1 mm (0 to 10) coronal translation, and 0.5 mm (0 to 2) sagittal
translation. All patients achieved consolidated bony union and satisfactory
wound healing. There were no cases of delayed or nonunion, compartment
syndrome or neurovascular injury. Four patients had a mild superficial
pin site infection; all settled with a single course of oral antibiotics.
No patient had a deep infection or re-fracture following removal
of the frame. The time to union was comparable with, or better than,
other published methods of stabilisation for these injuries. The
stable fixator configuration not only facilitates management of
the accompanying soft-tissue injury but enables anatomical post-injury
alignment, which is important in view of the limited remodelling
potential of the tibia in children aged >
ten years. Where appropriate
expertise exists, we recommend this technique for the management
of high-energy open tibial fractures in children.
Septicaemia resulting from meningococcal infection is a devastating illness affecting children. Those who survive can develop late orthopaedic sequelae from growth plate arrests, with resultant complex deformities. Our aim in this study was to review the case histories of a series of patients with late orthopaedic sequelae, all treated by the senior author (CFB). We also describe a treatment strategy to address the multiple deformities that may occur in these patients. Between 1997 and 2009, ten patients (seven girls and three boys) were treated for late orthopaedic sequelae following meningococcal septicaemia. All had involvement of the lower limbs, and one also had involvement of the upper limbs. Each patient had a median of three operations (one to nine). Methods of treatment included a combination of angular deformity correction, limb lengthening and epiphysiodesis. All patients were skeletally mature at the final follow-up. One patient with bilateral below-knee amputations had satisfactory correction of her right amputation stump deformity, and has complete ablation of both her proximal tibial growth plates. In eight patients length discrepancy in the lower limb was corrected to within 1 cm, with normalisation of the mechanical axis of the lower limb. Meningococcal septicaemia can lead to late orthopaedic sequelae due to growth plate arrests. Central growth plate arrests lead to limb-length discrepancy and the need for lengthening procedures, and peripheral growth plate arrests lead to angular deformities requiring corrective osteotomies and ablation of the damaged physis. In addition, limb amputations may be necessary and there may be altered growth of the stump requiring further surgery. Long-term follow-up of these patients is essential to recognise and treat any recurrence of deformity.
Between June 2001 and November 2008 a modified Dunn osteotomy with a surgical hip dislocation was performed in 30 hips in 28 patients with slipped capital femoral epiphysis. Complications and clinical and radiological outcomes after a mean follow-up of 3.8 years (1.0 to 8.5) were documented. Subjective outcome was assessed using the Harris hip score and the Western Ontario and McMaster Universities osteoarthritis index questionnaire. Anatomical or near-anatomical reduction was achieved in all cases. The epiphysis in one hip showed no perfusion intra-operatively and developed avascular necrosis. There was an excellent outcome in 28 hips. Failure of the implants with a need for revision surgery occurred in four hips. Anatomical reduction can be achieved by this technique, with a low risk of avascular necrosis. Cautious follow-up is necessary in order to avoid implant failure.
This study evaluated the results of a physeal-sparing technique of intra-articular anterior cruciate ligament (ACL) reconstruction in skeletally immature patients, with particular reference to growth disturbance. Between 1992 and 2007, 57 children with a mean age of 12.2 years (6.8 to 14.5) underwent ACL reconstruction using the same technique. At a mean of 5.5 years (2 to 14) after surgery, 56 patients underwent clinical and radiological evaluation. At that time, 49 patients (87.5%) had reached bony maturity and 53 (95%) achieved A or B according to the IKDC 2000 classification. Four patients had stopped participation in sports because of knee symptoms, and three patients (5.4%) had a subsequent recurrent ACL injury. There was no clinical or radiological evidence of growth disturbance after a mean growth in stature of 20.0 cm (3 to 38). This study demonstrates that ACL reconstruction sparing the physes in children is a safe technique protecting against meniscal tears and giving better results than reconstruction in adults, without causing significant growth disturbance.
We report the outcome of 28 patients with spina bifida who between 1989 and 2006 underwent 43 lower extremity deformity corrections using the Ilizarov technique. The indications were a flexion deformity of the knee in 13 limbs, tibial rotational deformity in 11 and foot deformity in 19. The mean age at operation was 12.3 years (5.2 to 20.6). Patients had a mean of 1.6 previous operations (0 to 5) on the affected limb. The mean duration of treatment with a frame was 9.4 weeks (3 to 26) and the mean follow-up was 4.4 years (1 to 9). There were 12 problems (27.9%), five obstacles (11.6%) and 13 complications (30.2%) in the 43 procedures. Further operations were needed in seven patients. Three knees had significant recurrence of deformity. Two tibiae required further surgery for recurrence. All feet were plantigrade and braceable. We conclude that the Ilizarov technique offers a refreshing approach to the complex lower-limb deformity in spina bifida.
We have reviewed our experience of the removal of deep extremity orthopaedic implants in children to establish the nature, rate and risk of complications associated with this procedure. A retrospective review was performed of 801 children who had 1223 implants inserted and subsequently removed over a period of 17 years. Bivariate analysis of possible predictors including clinical factors, complications associated with implant insertion and indications for removal and the complications encountered at removal was performed. A logistical regression model was then constructed using those predictors which were significantly associated with surgical complications from the bivariate analyses. Odds ratios estimated in the logistical regression models were converted to risk ratios. The overall rate of complications after removal of the implant was 12.5% (100 complications in 801 patients), with 48 (6.0%) major and 52 (6.5%) minor. Children with a complication after insertion of the initial implant or with a non-elective indication for removal, a neuromuscular disease associated with a seizure disorder or a neuromuscular disease in those unable to walk, had a significantly greater chance of having a major complication after removal of the implant. Children with all four of these predictors were 14.6 times more likely to have a major complication.
We report five children who presented at the mean age of 1.5 years (1.1 to 1.9) with a progressive thoracolumbar kyphosis associated with segmental instability and subluxation of the spine at the level above an anteriorly-wedged hypoplastic vertebra at L1 or L2. The spinal deformity appeared to be developmental and not congenital in origin. The anterior wedging of the vertebra may have been secondary to localised segmental instability and subsequent kyphotic deformity. We suggest the term ‘infantile developmental thoracolumbar kyphosis with segmental subluxation of the spine’ to differentiate this type of deformity from congenital displacement of the spine in which the congenital vertebral anomaly does not resolve. Infantile developmental kyphosis with segmental subluxation of the spine, if progressive, may carry the risk of neurological compromise. In all of our patients the kyphotic deformity progressed over a period of three months and all were treated by localised posterior spinal fusion. At a mean follow-up of 6.6 years (5.0 to 9.0), gradual correction of the kyphosis was seen on serial radiographs as well as reconstitution of the hypoplastic wedged vertebra to normality. Exploration of the arthrodesis was necessary at nine months in one patient who developed a pseudarthrosis.
