Paediatric triplane fractures and adult trimalleolar ankle fractures both arise from a supination external rotation injury. By relating the experience of adult to paediatric fractures, clarification has been sought on the sequence of injury, ligament involvement, and fracture pattern of triplane fractures. This study explores the similarities between triplane and trimalleolar fractures for each stage of the Lauge-Hansen classification, with the aim of aiding reduction and fixation techniques. Imaging data of 83 paediatric patients with triplane fractures and 100 adult patients with trimalleolar fractures were collected, and their fracture morphology was compared using fracture maps. Visual fracture maps were assessed, classified, and compared with each other, to establish the progression of injury according to the Lauge-Hansen classification.Aims

Triplane ankle fractures are complex injuries typically occurring in children aged between 12 and 15 years. Classic teaching that closure of the physis dictates the overall fracture pattern, based on studies in the 1960s, has not been challenged. The aim of this paper is to analyze whether these injuries correlate with the advancing closure of the physis with age. A fracture mapping study was performed in 83 paediatric patients with a triplane ankle fracture treated in three trauma centres between January 2010 and June 2020. Patients aged younger than 18 years who had CT scans available were included. An independent Paediatric Orthopaedic Trauma Surgeon assessed all CT scans and classified the injuries as n-part triplane fractures. Qualitative analysis of the fracture pattern was performed using the modified Cole fracture mapping technique. The maps were assessed for both patterns and correlation with the closing of the physis until consensus was reached by a panel of six surgeons.Aims

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
Studies of infant hip development to date have been limited by considering only the changes in appearance of a single ultrasound slice (Graf’s standard plane). We used 3D ultrasound (3DUS) to establish maturation curves of normal infant hip development, quantifying variation by age, sex, side, and anteroposterior location in the hip. We analyzed 3DUS scans of 519 infants (mean age 64 days (6 to 111 days)) presenting at a tertiary children’s hospital for suspicion of developmental dysplasia of the hip (DDH). Hips that did not require ultrasound follow-up or treatment were classified as ‘typically developing’. We calculated traditional DDH indices like α angle (αSP), femoral head coverage (FHCSP), and several novel indices from 3DUS like the acetabular contact angle (ACA) and osculating circle radius (OCR) using custom software.Aims

The aim of this study was to compare outcomes of guided growth and varus osteotomy in treating Kalamchi type II avascular necrosis (AVN) after open reduction and Pemberton acetabuloplasty for developmental dysplasia of the hip (DDH). This retrospective study reviewed patients undergoing guided growth or varus osteotomy for Kalamchi type II AVN between September 2009 and January 2019. All children who had undergone open reduction and Pemberton acetabuloplasty for DDH with a minimum two-year follow-up were enrolled in the study. Demographic and radiological data, which included the head-shaft angle (HSA), neck-shaft angle (NSA), articulotrochanteric distance (ATD), Sharp angle (SA), and lateral centre-edge angle (LCEA) at baseline, two years, and at the extended follow-up, were compared. Revision rates were evaluated. Clinical outcomes using the Harris Hip Score were assessed two years postoperatively.Aims
Methods
Slipped upper femoral epiphysis (SUFE) has well documented biochemical and mechanical risk factors. Femoral and acetabular morphologies seem to be equally important. Acetabular retroversion has a low prevalence in asymptomatic adults. Hips with dysplasia, osteoarthritis, and Perthes’ disease, however, have higher rates, ranging from 18% to 48%. The aim of our study was to assess the prevalence of acetabular retroversion in patients presenting with SUFE using both validated radiological signs and tomographical measurements. A retrospective review of all SUFE surgical cases presenting to the Royal Children’s Hospital, Melbourne, Australia, from 2012 to 2019 were evaluated. Preoperative plain radiographs were assessed for slip angle, validated radiological signs of retroversion, and standardized postoperative CT scans were used to assess cranial and mid-acetabular version.Aims

Aims. 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. Methods. 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. Results. The mean LLD was reduced from 25.2 mm (15 to 45) before surgery to 9.3 mm (6 to 25) at skeletal maturity. Implant-associated complications occurred in 4/56 treatments (7%), and secondary frontal plane deformities were detected in 5/45 legs (11%) of the LLD cohort. Including tall stature patients, the rate increased to 12/67 legs (18%).
Open tibial fractures are limb-threatening injuries. While limb loss is rare in children, deep infection and nonunion rates of up to 15% and 8% are reported, respectively. We manage these injuries in a similar manner to those in adults, with a combined orthoplastic approach, often involving the use of vascularised free flaps. We report the orthopaedic and plastic surgical outcomes of a consecutive series of patients over a five-year period, which includes the largest cohort of free flaps for trauma in children to date. Data were extracted from medical records and databases for patients with an open tibial fracture aged < 16 years who presented between 1 May 2014 and 30 April 2019. Patients who were transferred from elsewhere were excluded, yielding 44 open fractures in 43 patients, with a minimum follow-up of one year. Management was reviewed from the time of injury to discharge. Primary outcome measures were the rate of deep infection, time to union, and the Modified Enneking score.Aims
Methods
Though the pathogenesis of Legg-Calve-Perthes disease (LCPD) is unknown, repetitive microtrauma resulting in deformity has been postulated. The purpose of this study is to trial a novel upright MRI scanner, to determine whether any deformation occurs in femoral heads affected by LCPD with weightbearing. Children affected by LCPD were recruited for analysis. Children received both standing weightbearing and supine scans in the MROpen upright MRI scanner, for coronal T1 GFE sequences, both hips in field of view. Parameters of femoral head height, width, and lateral extrusion of affected and unaffected hips were assessed by two independent raters, repeated at a one month interval. Inter- and intraclass correlation coefficients were determined. Standing and supine measurements were compared for each femoral head.Aims
Methods
Guided growth using eight-plates is commonly used for correction
of angular limb deformities in growing children. The principle is
of tethering at the physeal periphery while enabling growth in the
rest of the physis. The method is also applied for epiphysiodesis
to correct limb-length discrepancy (LLD). Concerns have been raised
regarding the potential of this method to create an epiphyseal deformity.
However, this has not been investigated. The purpose of this study
was to detect and quantify the occurrence of deformities in the
proximal tibial epiphysis following treatment with eight-plates. A retrospective study was performed including 42 children at
a mean age of 10.8 years (3.7 to 15.7) undergoing eight-plate insertion
in the proximal tibia for correction of coronal plane deformities
or LLD between 2007 and 2015. A total of 64 plates were inserted;
48 plates (34 patients) were inserted to correct angular deformities
and 16 plates (8 patients) for LLD. Medical records, Picture Archive
and Communication System images, and conventional radiographs were
reviewed. Measurements included interscrew angle, lateral and medial
plateau slope angles measured between the plateau surface and the
line between the ends of the physis, and tibial plateau roof angle defined
as 180° minus the sum of both plateau angles. Measurements were
compared between radiographs performed adjacent to surgery and those
at latest follow-up, and between operated and non-operated plateaus. Statistical
analysis was performed using BMDP Statistical Software.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
This pilot study aimed to evaluate prospectively the use of inlet
radiographs of the hip as an alternative method of the assessment
of reduction after the surgical treatment of developmental dysplasia
of the hip (DDH). The children in this study underwent surgery between January
2013 and January 2015. All had inlet radiographs and CT scans post-operatively.
Data were analysed by determining inter-observer reliability and
intra-observer reproducibility, using the kappa value (K). Differences
were settled by discussion between the two observers until a consensus
was reached. The sensitivity and specificity of the radiographic
and CT results were compared. A total of 26 radiographs were obtained
from 23 children, with a mean age of 2.38 years (one to five).Aims
Patients and Methods
The traditional techniques involving an oblique
tunnel or triangular wedge resection to approach a central or mixed-type
physeal bar are hindered by poor visualisation of the bar. This
may be overcome by a complete transverse osteotomy at the metaphysis
near the growth plate or a direct vertical approach to the bar.
Ilizarov external fixation using small wires allows firm fixation
of the short physis-bearing fragment, and can also correct an associated angular
deformity and permit limb lengthening. We accurately approached and successfully excised ten central-
or mixed-type bars; six in the distal femur, two in the proximal
tibia and two in the distal tibia, without damaging the uninvolved
physis, and corrected the associated angular deformity and leg-length
discrepancy. Callus formation was slightly delayed because of periosteal
elevation and stretching during resection of the bar. The resultant
resection of the bar was satisfactory in seven patients and fair
in three as assessed using a by a modified Williamson–Staheli classification. Cite this article:
A retrospective study was performed in 18 patients
with achondroplasia, who underwent bilateral humeral lengthening
between 2001 and 2013, using monorail external fixators. The mean
age was ten years (six to 15) and the mean follow-up was 40 months
(12 to 104). The mean disabilities of the arm, shoulder and hand (DASH) score
fell from 32.3 (20 to 40)
pre-operatively to 9.4 (6 to 14) post-operatively (p = 0.037). A
mean lengthening of 60% (40% to 95%) was required to reach the goal
of independent perineal hygiene. One patient developed early consolidation,
and fractures occurred in the regenerate bone of four humeri in
three patients. There were three transient radial nerve palsies. Humeral lengthening increases the independence of people with
achondroplasia and is not just a cosmetic procedure. Cite this article:
Cubitus varus is the most frequent complication
following the treatment of supracondylar humeral fractures in children.
We investigated data from publications reporting on the surgical
management of cubitus varus found in electronic searches of Ovid/MEDLINE
and Cochrane Library databases. In 894 children from 40 included
studies, the mean age at initial injury was 5.7 years (3 to 8.6)
and 9.8 years (4 to 15.7) at the time of secondary correction. The four
osteotomy techniques were classified as lateral closing wedge, dome,
complex (multiplanar) and distraction osteogenesis. A mean angular
correction of 27.6º (18.5° to 37.0°) was achieved across all classes
of osteotomy. The meta-analytical summary estimate for overall rate
of good to excellent results was 87.8% (95% CI 84.4 to 91.2). No technique
was shown to significantly affect the surgical outcome, and the
risk of complications across all osteotomy classes was 14.5% (95%
CI 10.6 to 18.5). Nerve palsies occurred in 2.53% of cases (95%
CI 1.4 to 3.6), although 78.4% were transient. No one technique
was found to be statistically safer or more effective than any other. Cite this article:
We describe the technique and results of medial
submuscular plating of the femur in paediatric patients and discuss its
indications and limitations. Specifically, the technique is used
as part of a plate-after-lengthening strategy, where the period
of external fixation is reduced and the plate introduced by avoiding
direct contact with the lateral entry wounds of the external fixator
pins. The technique emphasises that vastus medialis is interposed
between the plate and the vascular structures. A total of 16 patients (11 male and five female, mean age 9.6
years (5 to 17)), had medial submuscular plating of the femur. All
underwent distraction osteogenesis of the femur with a mean lengthening
of 4.99 cm (3.2 to 12) prior to plating. All patients achieved consolidation
of the regenerate without deformity. The mean follow-up was 10.5 months
(7 to 15) after plating for those with plates still Placing the plate on the medial side is advantageous when the
external fixator is present on the lateral side, and is biomechanically
optimal in the presence of a femoral defect. We conclude that medial
femoral submuscular plating is a useful technique for specific indications
and can be performed safely with a prior understanding of the regional
anatomy. Cite this article:
Redisplacement is the most common complication
of immobilisation in a cast for the treatment of diaphyseal fractures
of the forearm in children. We have previously shown that the three-point
index (TPI) can accurately predict redisplacement of fractures of
the distal radius. In this prospective study we applied this index
to assessment of diaphyseal fractures of the forearm in children
and compared it with other cast-related indices that might predict
redisplacement. A total of 76 children were included. Their ages,
initial displacement, quality of reduction, site and level of the
fractures and quality of the casting according to the TPI, Canterbury
index and padding index were analysed. Logistic regression analysis
was used to investigate risk factors for redisplacement. A total
of 18 fractures (24%) redisplaced in the cast. A TPI value of >
0.8 was the only significant risk factor for redisplacement (odds
ratio 238.5 (95% confidence interval 7.063 to 8054.86); p <
0.001). The TPI was far superior to other radiological indices, with
a sensitivity of 84% and a specificity of 97% in successfully predicting
redisplacement. We recommend it for routine use in the management
of these fractures in children. Cite this article:
We present our experience of the modified Dunn
procedure in combination with a Ganz surgical dislocation of the hip
to treat patients with severe slipped capital femoral epiphysis
(SCFE). The aim was to prospectively investigate whether this technique
is safe and reproducible. We assessed the degree of reduction, functional
outcome, rate of complications, radiological changes and range of
movement in the hip. There were 28 patients with a mean follow-up
of 38.6 months (24 to 84). The lateral slip angle was corrected
by a mean of 50.9° (95% confidence interval 44.3 to 57.5). The mean
modified Harris hip score at the final follow-up was 89.1 ( Cite this article:
Although equinus gait is the most common abnormality
in children with spastic cerebral palsy (CP) there is no consistency
in recommendations for treatment, and evidence for best practice
is lacking. The Baumann procedure allows selective fractional lengthening
of the gastrocnemii and soleus muscles but the long-term outcome
is not known. We followed a group of 18 children (21 limbs) with
diplegic CP for ten years using three-dimensional instrumented gait
analysis. The kinematic parameters of the ankle joint improved significantly
following this procedure and were maintained until the end of follow-up.
We observed a normalisation of the timing of the key kinematic and
kinetic parameters, and an increase in the maximum generation of
power of the ankle. There was a low rate of overcorrection (9.5%,
n = 2), and a rate of recurrent equinus similar to that found with
other techniques (23.8%, n = 5). As the procedure does not impair the muscle architecture, and
allows for selective correction of the contracted gastrocnemii and
soleus, it may be recommended as the preferred method for correction
of a mild fixed equinus deformity.
Percutaneous epiphysiodesis using transphyseal
screws (PETS) has been developed for the treatment of lower limb discrepancies
with the aim of replacing traditional open procedures. The goal
of this study was to evaluate its efficacy and safety at skeletal
maturity. A total of 45 consecutive patients with a mean skeletal
age of 12.7 years (8.5 to 15) were included and followed until maturity.
The mean efficacy of the femoral epiphysiodesis was 35% (14% to 87%)
at six months and 66% (21% to 100%) at maturity. The mean efficacy
of the tibial epiphysiodesis was 46% (18% to 73%) at six months
and 66% (25% to 100%) at maturity. In both groups of patients the
under-correction was significantly reduced between six months post-operatively
and skeletal maturity. The overall rate of revision was 18% (eight
patients), and seven of these revisions (87.5%) involved the tibia.
This series showed that use of the PETS technique in the femur was
safe, but that its use in the tibia was associated with a significant
rate of complications, including a valgus deformity in nine patients
(20%), leading us to abandon it in the tibia. The arrest of growth
was delayed and the final loss of growth at maturity was only 66%
of that predicted pre-operatively. This should be taken into account
in the pre-operative planning.
