the outcomes of re-dislocation of the radial head after corrective osteotomy
for chronic dislocation. A total of 12 children with a mean age
of 11 years (5 to 16), with further dislocation of the radial head
after corrective osteotomy of the forearm, were followed for a mean
of five years (2 to 10). Re-operations were performed for radial
head re-dislocation in six children, while the other six did not
undergo re-operation (‘non-re-operation group’). The active range

There is a lack of high-quality research investigating outcomes of Ponseti-treated idiopathic clubfeet and correlation with relapse. This study assessed clinical and quality of life (QoL) outcomes using a standardized core outcome set (COS), comparing children with and without relapse. A total of 11 international centres participated in this institutional review board-approved observational study. Data including demographics, information regarding presentation, treatment, and details of subsequent relapse and management were collected between 1 June 2022 and 30 June 2023 from consecutive clinic patients who had a minimum five-year follow-up. The clubfoot COS incorporating 31 parameters was used. A regression model assessed relationships between baseline variables and outcomes (clinical/QoL).Aims

To examine the long-term outcome of arthrodesis of the hip undertaken in a paediatric population in treating painful arthritis of the hip. In our patient population, most of whom live rurally in hilly terrain and have limited healthcare access and resources, hip arthrodesis has been an important surgical option for the monoarticular painful hip in a child. A follow-up investigation was undertaken on a cohort of 28 children previously reported at a mean of 4.8 years. The present study looked at 26 patients who had an arthrodesis of the hip as a child at a mean follow-up of 20 years (15 to 29).Aims

Reimers migration percentage (MP) is a key measure to inform decision-making around the management of hip displacement in cerebral palsy (CP). The aim of this study is to assess validity and inter- and intra-rater reliability of a novel method of measuring MP using a smart phone app (HipScreen (HS) app). A total of 20 pelvis radiographs (40 hips) were used to measure MP by using the HS app. Measurements were performed by five different members of the multidisciplinary team, with varying levels of expertise in MP measurement. The same measurements were repeated two weeks later. A senior orthopaedic surgeon measured the MP on picture archiving and communication system (PACS) as the gold standard and repeated the measurements using HS app. Pearson’s correlation coefficient (r) was used to compare PACS measurements and all HS app measurements and assess validity. Intraclass correlation coefficient (ICC) was used to assess intra- and inter-rater reliability.Aims

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
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
Methods
Multiple secondary surgical procedures of the shoulder, such as soft-tissue releases, tendon transfers, and osteotomies, are described in brachial plexus birth palsy (BPBP) patients. The long-term functional outcomes of these procedures described in the literature are inconclusive. We aimed to analyze the literature looking for a consensus on treatment options. A systematic literature search in healthcare databases (PubMed, Embase, the Cochrane library, CINAHL, and Web of Science) was performed from January 2000 to July 2020, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The quality of the included studies was assessed with the Cochrane ROBINS-I risk of bias tool. Relevant trials studying BPBP with at least five years of follow-up and describing functional outcome were included.Aims
Methods
To identify the minimum set of outcomes that should be collected in clinical practice and reported in research related to the care of children with idiopathic congenital talipes equinovarus (CTEV). A list of outcome measurement tools (OMTs) was obtained from the literature through a systematic review. Further outcomes were collected from patients and families through a questionnaire and interview process. The combined list, as well as the appropriate follow-up timepoint, was rated for importance in a two-round Delphi process that included an international group of orthopaedic surgeons, physiotherapists, nurse practitioners, patients, and families. Outcomes that reached no consensus during the Delphi process were further discussed and scored for inclusion/exclusion in a final consensus meeting involving international stakeholder representatives of practitioners, families, and patient charities.Aims

In five children, six forearms with a fixed pronation deformity secondary to congenital radioulnar synostosis were treated by a derotation osteotomy of the distal radius and the midshaft of the ulna. There were three boys and two girls with a mean age of 4.9 years (3.5 to 8.25) who were followed up for a mean of 29 months (18 to 43). The position of the forearm was improved from a mean pronation deformity of 68° (40° to 80°) to a pre-planned position of 10° of
We reviewed 15 patients, nine girls and six boys, with chronic anterior dislocation of the radial head which was treated by ulnar osteotomy, external fixation and open reconstruction of the elbow joint but without repair of the annular ligament. Their mean age was 9.5 years (5 to 15) and the mean interval between the injury and reconstruction was 22 months (2 months to 7 years). All radial heads remained reduced at a mean follow-up of 20 months (6 months to 5 years). Normal ranges of movement for flexion, extension, pronation and
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. 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.Aims

We aimed to determine hip-related quality of life and clinical findings following treatment for neonatal hip instability (NHI) compared with age- and sex-matched controls. We hypothesized that NHI would predispose to hip discomfort in long-term follow-up. We invited those born between 1995 and 2001 who were treated for NHI at our hospital to participate in this population-based study. We included those that had Von Rosen-like splinting treatment started before one month of age. A total of 96 patients treated for NHI (75.6 %) were enrolled. A further 94 age- and sex-matched controls were also recruited. The Copenhagen Hip and Groin Outcome Score (HAGOS) questionnaire was completed separately for both hips, and a physical examination was performed.Aims
Methods
Hip displacement, common in patients with cerebral palsy (CP), causes pain and hinders adequate care. Hip reconstructive surgery (HRS) is performed to treat hip displacement; however, only a few studies have quantitatively assessed femoral head sphericity after HRS. The aim of this study was to quantitatively assess improvement in hip sphericity after HRS in patients with CP. We retrospectively analyzed hip radiographs of patients who had undergone HRS because of CP-associated hip displacement. The pre- and postoperative migration percentage (MP), femoral neck-shaft angle (NSA), and sphericity, as determined by the Mose hip ratio (MHR), age at surgery, Gross Motor Function Classification System level, surgical history including Dega pelvic osteotomy, and triradiate cartilage status were studied. Regression analyses using linear mixed model were performed to identify factors affecting hip sphericity improvement.Aims
Methods
We aimed to address the question on whether there is a place for shoulder stabilization surgery in patients who had voluntary posterior instability starting in childhood and adolescence, and later becoming involuntary and uncontrollable. Consecutive patients who had an operation for recurrent posterior instability before the age of 18 years were studied retrospectively. All patients had failed conservative treatment for at least six months prior to surgery; and no patients had psychiatric disorders. Two groups were identified and compared: voluntary posterior instability starting in childhood which became uncontrollable and involuntary (group VBI); and involuntary posterior instability (group I). Patients were reviewed and assessed at least two years after surgery by two examiners.Aims
Methods
The diagnosis of developmental dysplasia of the hip (DDH) is challenging owing to extensive variation in paediatric pelvic anatomy. Artificial intelligence (AI) may represent an effective diagnostic tool for DDH. Here, we aimed to develop an anteroposterior pelvic radiograph deep learning system for diagnosing DDH in children and analyze the feasibility of its application. In total, 10,219 anteroposterior pelvic radiographs were retrospectively collected from April 2014 to December 2018. Clinicians labelled each radiograph using a uniform standard method. Radiographs were grouped according to age and into ‘dislocation’ (dislocation and subluxation) and ‘non-dislocation’ (normal cases and those with dysplasia of the acetabulum) groups based on clinical diagnosis. The deep learning system was trained and optimized using 9,081 radiographs; 1,138 test radiographs were then used to compare the diagnoses made by deep learning system and clinicians. The accuracy of the deep learning system was determined using a receiver operating characteristic curve, and the consistency of acetabular index measurements was evaluated using Bland-Altman plots.Aims

Eight-plates are used to correct varus-valgus deformity (VVD) or limb-length discrepancy (LLD) in children and adolescents. It was reported that these implants might create a bony deformity within the knee joint by change of the roof angle (RA) after epiphysiodesis of the proximal tibia following a radiological assessment limited to anteroposterior (AP) radiographs. The aim of this study was to analyze the RA, complemented with lateral knee radiographs, with focus on the tibial slope (TS) and the degree of deformity correction. A retrospective, single-centre study was conducted. The treatment group (n = 64 knees in 44 patients) was subclassified according to the implant location in two groups: 1) medial hemiepiphysiodesis; and 2) lateral hemiepiphysiodesis. A third control group consisted of 25 untreated knees. The limb axes and RA were measured on long standing AP leg radiographs. Lateral radiographs of 40 knees were available for TS analysis. The mean age of the patients was 10.6 years (4 to 15) in the treatment group and 8.4 years (4 to 14) in the control group. Implants were removed after a mean 1.2 years (0.5 to 3).Aims

Transfer of flexor carpi ulnaris combined with selective release of the flexor pronator origin was undertaken in 35 patients with hemiplegic cerebral palsy for a pronation flexion deformity of the forearm, hand and wrist. The patients were divided into four groups depending on the severity of the deformity, the surgical procedure recommended, potential hand function and prognosis. The procedure reduces the power of wrist and finger flexion by release of the flexor pronator origin, and reinforces the strength of extension and
Guided growth has been used to treat coxa valga for cerebral palsy (CP) children. However, there has been no study on the optimal position of screw application. In this paper we have investigated the influence of screw position on the outcomes of guided growth. We retrospectively analyzed 61 hips in 32 CP children who underwent proximal femoral hemi epiphysiodesis between July 2012 and September 2017. The hips were divided into two groups according to the transphyseal position of the screw in the coronal plane: across medial quarter (Group 1) or middle quarter (Group 2) of the medial half of the physis. We compared pre- and postoperative radiographs in head-shaft angle (HSA), Reimer’s migration percentage (MP), acetabular index (AI), and femoral anteversion angle (FAVA), as well as incidences of the physis growing-off the screw within two years. Linear and Cox regression analysis were conducted to identify factors related to HSA correction and risk of the physis growing-off the screw.Aims

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,
To describe and analyze the mid-term functional outcomes of a large series of patients who underwent the Hoffer procedure for brachial plexus birth palsy (BPBP). All patients who underwent the Hoffer procedure with minimum two-year follow-up were retrospectively reviewed. Active shoulder range of movement (ROM), aggregate modified Mallet classification scores, Hospital for Sick Children Active Movement Scale (AMS) scores, and/or Toronto Test Scores were used to assess functional outcomes. Subgroup analysis based on age and level of injury was performed. Risk factors for subsequent humeral derotational osteotomy and other complications were also assessed. A total of 107 patients, average age 3.9 years (1.6 to 13) and 59% female, were included in the study with mean 68 months (24 to 194) follow-up.Aims
Methods
Unstable fractures of the forearm in children present problems in management and in the indications for operative treatment. In children, unlike adults, the fractures nearly always unite, and up to 10° of angulation is usually considered to be acceptable. If surgical intervention is required the usual practice in the UK is to plate both bones as in an adult. We studied, retrospectively, 32 unstable fractures of the forearm in children treated by compression plating. Group A (20 children) had conventional plating of both forearm bones and group B (12 children) had plating of the ulna only. The mean age was 11 years in both groups and 23 (71%) of the fractures were in the midshaft. In group B an acceptable position of the radius was regarded as less than 10° of angulation in both anteroposterior (AP) and lateral planes, and with the bone ends hitched. This was achieved by closed means in all except two cases, which were therefore included in group A. Union was achieved in all patients, the mean time being 9.8 weeks in group A and 11.5 weeks in B. After a mean interval of at least 12 months, 14 children in group A and nine in group B had their fixation devices removed. We analysed the results after the initial operation in all 32 children. The 23 who had the plate removed were assessed at final review. The results were graded on the ability to undertake physical activities and an objective assessment of loss of rotation of the forearm. In group A, complications were noted in eight patients (40%) after fixation and in six (42%) in relation to removal of the radial plate. No complications occurred in group B. The final range of movement and radiological appearance were compared in the two groups. There was a greater loss of pronation than
Delayed diagnosis is a well-known complication of a Monteggia
fracture-dislocation. If left untreated, the dislocated radial head
later becomes symptomatic. The purposes of this study were firstly,
to evaluate the clinical and radiological results of open reduction
of the radial head and secondly, to identify the factors that may
affect the outcome of this procedure. This retrospective study evaluated 30 children with a chronic
Monteggia lesion. There were 18 boys and 12 girls with a mean age
of 7.4 years (4 to 13) at the time of open reduction. The mean interval
to surgery, after the initial fracture, was 23.4 months (6 to 120).
Clinical grading used a Kim modified elbow score: radiological outcome
was recorded. The effect of the patient’s age, gender, duration
from initial injury, Bado classification, and annular ligament reconstruction
were analyzed. The mean follow-up was 42.2 months (15 to 20).Aims

Salter’s criteria and Kalamchi’s classification of avascular necrosis
in patients treated for developmental dysphasia of the hip (DDH). The study involved a retrospective analysis of 123 patients (123
hips) with DDH treated by operative and non-operative reduction
before the age of two years, with a minimum follow-up of ten years.
Salter’s criteria (S1 to S4) were determined from radiographs obtained
at one to two years post-reduction, whilst the Kalamchi grade was determined
from radiographs obtained at ten or more years of age. Early post-reduction
radiographs were also used to evaluate the centre-head distance
discrepancy (CHDD) and the occurrence of a dome-shaped deformity
of the proximal femoral metaphysis (D-shaped metaphysis). The prognosis was described as good (Kalamchi grade K0 or KI),
fair (Kalamchi grade KII) or poor (Kalamchi grade KIII or KIV) for
analysis and correlation with the early Salter criteria, CHDD and
D-shaped metaphysis.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. A total of 15 children (ten boys, five girls) with idiopathic
clubfoot were evaluated at a mean of 6.8 years (5.4 to 8.1) after
complete percutaneous division of the Achilles tendon. The contour
and subjective thickness of the tendon were recorded, and superficial
defects and its strength were assessed clinically. The echogenicity,
texture, thickness, peritendinous irregularities and potential for
deformation of the tendon were evaluated by ultrasonography.Aims

Slipped upper femoral epiphysis (SUFE) is the
most common hip disorder to affect adolescents. Controversy exists over
the optimal treatment of severe slips, with a continuing debate
between Between 2001 and 2011, 57 patients (35 male, 22 female) with
a mean age of 13.1 years (9.6 to 20.3, SD 2.3) were referred to
our tertiary referral institution with a severe slip. The affected
limb was rested in slings and springs before corrective surgery
which was performed via an anterior Smith-Petersen approach. Radiographic
analysis confirmed an improvement in mean head–shaft slip angle

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:
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. Cite this article:
Our goal was to evaluate the use of Ponseti’s
method, with minor adaptations, in the treatment of idiopathic clubfeet
presenting in children between five and ten years of age. A retrospective
review was performed in 36 children (55 feet) with a mean age of
7.4 years (5 to 10), supplemented by digital images and video recordings
of gait. There were 19 males and 17 females. The mean follow-up
was 31.5 months (24 to 40). The mean number of casts was 9.5 (6
to 11), and all children required surgery, including a percutaneous
tenotomy or open tendo Achillis lengthening (49%), posterior release
(34.5%), posterior medial soft-tissue release (14.5%), or soft-tissue
release combined with an osteotomy (2%). The mean dorsiflexion of
the ankle was 9° (0° to 15°). Forefoot alignment was neutral in
28 feet (51%) or adducted (<
10°) in 20 feet (36%), >
10° in
seven feet (13%). Hindfoot alignment was neutral or mild valgus
in 26 feet (47%), mild varus (<
10°) in 19 feet (35%), and varus
(>
10°) in ten feet (18%). Heel–toe gait was present in 38 feet
(86%), and 12 (28%) exhibited weight-bearing on the lateral border
(out of a total of 44 feet with gait videos available for analysis).
Overt relapse was identified in nine feet (16%, six children). The
parents of 27 children (75%) were completely satisfied. A plantigrade foot was achieved in 46 feet (84%) without an extensive
soft-tissue release or bony procedure, although under-correction
was common, and longer-term follow-up will be required to assess
the outcome. Cite this article:

Salter innominate osteotomy is an effective reconstructive
procedure for the treatment of developmental dysplasia of the hip
(DDH), but some children have a poor outcome at skeletal maturity.
In order to investigate factors associated with an unfavourable
outcome, we assessed the development of the contralateral hip. We retrospectively
reviewed 46 patients who underwent a unilateral Salter osteotomy
at between five and seven years of age, with a mean follow-up of
10.3 years (7 to 20). The patients were divided into three groups
according to the centre–edge angle (CEA) of the contralateral hip
at skeletal maturity: normal (>
25°, 22 patients), borderline (20°
to 25°, 17 patients) and dysplastic (<
20°, 7 patients). The
CEA of the affected hip was measured pre-operatively, at eight to
nine years of age, at 11 to 12 years of age and at skeletal maturity.
The CEA of the affected hip was significantly smaller in the borderline
and dysplastic groups at 11 and 12 years of age (p = 0.012) and
at skeletal maturity (p = 0.017) than in the normal group. Severin
group III was seen in two (11.8%) and four hips (57.1%) of the borderline
and dysplastic groups, respectively (p <
0.001). Limited individual development of the acetabulum was associated
with an unfavourable outcome following Salter osteotomy. Cite this article:
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.
We investigated the predictive value of intra-operative
neurophysiological investigations in obstetric brachial plexus injuries.
Between January 2005 and June 2011 a total of 32 infants of 206
referred to our unit underwent exploration of the plexus, including
neurolysis. The findings from intra-operative electromyography,
sensory evoked potentials across the lesion and gross muscular response
to stimulation were evaluated. A total of 22 infants underwent neurolysis
alone and ten had microsurgical reconstruction. Of the former, one
was lost to follow-up, one had glenoplasty and three had subsequent
nerve reconstructions. Of the remaining 17 infants with neurolysis,
13 (76%) achieved a modified Mallet score >
13 at a mean age of
3.5 years (0.75 to 6.25). Subluxation or dislocation of the shoulder
is a major confounding factor. The positive predictive value and
sensitivity of the intra-operative EMG for C5 were 100% and 85.7%,
respectively, in infants without concurrent shoulder pathology.
The positive and negative predictive values, sensitivity and specificity
of the three investigations combined were 77%, 100%, 100% and 57%, respectively. In all, 20 infants underwent neurolysis alone for C6 and three
had reconstruction. All of the former and one of the latter achieved
biceps function of Raimondi grade 5. The positive and negative predictive
values, sensitivity and specificity of electromyography for C6 were
65%, 71%, 87% and 42%, respectively. Our method is effective in evaluating the prognosis of C5 lesion.
Neurolysis is preferred for C6 lesions. Cite this article:
A total of 38 relapsed congenital clubfeet (16 stiff, 22 partially correctable) underwent revision of soft-tissue surgery, with or without a bony procedure, and transfer of the tendon of tibialis anterior at a mean age of 4.8 years (2.0 to 10.1). The tendon was transferred to the third cuneiform in five cases, to the base of the third metatarsal in ten and to the base of the fourth in 23. The patients were reviewed at a mean follow-up of 24.8 years (10.8 to 35.6). A total of 11 feet were regarded as failures (one a tendon failure, five with a subtalar fusion due to over-correction, and five with a triple arthrodesis due to under-correction or relapse). In the remaining feet the clinical outcome was excellent or good in 20 and fair or poor in seven. The mean Laaveg-Ponseti score was 81.6 of 100 points (52 to 92). Stiffness was mild in four feet and moderate or severe in 23. Comparison between the post-operative and follow-up radiographs showed statistically significant variations of the talo-first metatarsal angle towards abduction. Variations of the talocalcaneal angles and of the overlap ratio were not significant. Extensive surgery for relapsed clubfoot has a high rate of poor long-term results. The addition of transfer of the tendon of tibialis anterior can restore balance and may provide some improvement of forefoot adduction. However, it has a considerable complication rate, including failure of transfer, over-correction, and weakening of dorsiflexion. The procedure should be reserved for those limited cases in which muscle imbalance is a causative or contributing factor.
We reviewed the results of a selective à la carte soft-tissue release operation for recurrent or residual deformity after initial conservative treatment for idiopathic clubfoot by the Ponseti method. Recurrent or residual deformity occurred in 13 (19 feet) of 33 patients (48 feet; 40%). The mean age at surgery was 2.3 years (1.3 to 4) and the mean follow-up was 3.6 years (2 to 5.3). The mean Pirani score had improved from 2.8 to 1.1 points, and the clinical and radiological results were satisfactory in all patients. However, six of the 13 patients (9 of 19 feet) had required further surgery in the form of tibial derotation osteotomy, split anterior tibialis tendon transfer, split posterior tibialis transfer or a combination of these for recurrent deformity. We concluded that selective soft-tissue release can provide satisfactory early results after failure of initial treatment of clubfoot by the Ponseti method, but long-term follow-up to skeletal maturity will be necessary.
In Norway total joint replacement after hip dysplasia
is reported more commonly than in neighbouring countries, implying
a higher prevalence of the condition. We report on the prevalence
of radiological features associated with hip dysplasia in a population
of
2081 19-year-old Norwegians. The radiological measurements used
to define hip dysplasia were Wiberg’s centre-edge (CE) angle at
thresholds of <
20° and <
25°, femoral head extrusion index
<
75%, Sharp’s angle >
45°, an acetabular depth to width ratio
<
250 and the sourcil shape assessed subjectively. The whole
cohort underwent clinical examination of their range of hip movement,
body mass index (BMI), and Beighton hypermobility score, and were
asked to complete the EuroQol (EQ-5D) and Western Ontario and McMaster
Universities Osteoarthritis Index (WOMAC). The prevalence of hip
dysplasia in the cohort varied from 1.7% to 20% depending on the
radiological marker used. A Wiberg’s CE angle <
20° was seen
in 3.3% of the cohort: 4.3% in women and 2.4% in men. We found no
association between subjects with multiple radiological signs indicative
of dysplasia and BMI, Beighton score, EQ-5D or WOMAC. Although there
appears to be a high prevalence of hip dysplasia among 19-year-old
Norwegians, this is dependent on the radiological parameters applied. Cite this article:
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:
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:
Most surgeons favour removing forearm plates
in children. There is, however, no long-term data regarding the complications
of retaining a plate. We present a prospective case series of 82
paediatric patients who underwent plating of their forearm fracture
over an eight-year period with a minimum follow-up of two years.
The study institution does not routinely remove forearm plates.
A total of 116 plates were used: 79 one-third tubular plates and 37 dynamic
compression plates (DCP). There were 12 complications: six plates
(7.3%) were removed for pain or stiffness and there were six (7.3%)
implant-related fractures. Overall, survival of the plates was 85%
at 10 years. Cox regression analysis identified radial plates (odds
ratio (OR) 4.4, p = 0.03) and DCP fixation (OR 3.2, p = 0.02) to
be independent risk factors of an implant-related fracture. In contrast
ulnar plates were more likely to cause pain or irritation necessitating
removal (OR 5.6, p = 0.04). The complications associated with retaining a plate are different,
but do not occur more frequently than the complications following
removal of a plate in children.
We analysed the operative technique, morbidity and functional outcome of osteotomy and plate fixation for malunited fractures of the forearm sustained in childhood. A total of 20 consecutive patients underwent corrective osteotomy of 21 malunited fractures at a mean age of 12 years (4 to 25). The mean time between the injury and the osteotomy was 30 months (2 to 140). After removal of the plate, one patient suffered transient dysaesthesia of the superficial radial nerve. The mean gain in the range of movement was 85° (20° to 140°). The interval between injury and osteotomy, and the age at osteotomy significantly influenced the functional outcome (p = 0.011 and p = 0.004, respectively). Malunited fractures of the forearm sustained in childhood can be adequately treated by osteotomy and plate fixation with excellent functional results and minimal complications. In the case of established malunion it is advisable to perform corrective osteotomy without delay.
The medial rotation contracture caused by weak external rotation secondary to obstetric brachial plexus injury leads to deformation of the bones of the shoulder. Scapular hypoplasia, elevation and rotation deformity are accompanied by progressive dislocation of the humeral head. Between February and August 2005, 44 children underwent a new surgical procedure called the ‘triangle tilt’ operation to correct this bony shoulder deformity. Surgical levelling of the distal acromioclavicular triangle combined with tightening of the posterior glenohumeral capsule (capsulorrhaphy) improved shoulder function and corrected the glenohumeral axis in these patients. The posture of the arm at rest was improved and active external rotation increased by a mean of 53° (0° to 115°) in the 40 children who were followed up for more than one year. There was a mean improvement of 4.9 points (1.7 to 8.3) of the Mallet shoulder function score after surgical correction of the bony deformity.
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:
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:
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:
