Aims. The paediatric trigger thumb is a distinct clinical entity with unique anatomical abnormalities. The aim of this study was to present the long-term outcomes of A1 pulley release in idiopathic paediatric trigger thumbs based on established patient-reported outcome measures. Methods. This study was a cross-sectional, questionnaire-based study conducted at a tertiary care orthopaedic centre. All cases of idiopathic paediatric trigger thumbs which underwent A1 pulley release between 2004 and 2011 and had a minimum follow-up period of ten years were included in the study. The abbreviated version of the Disabilities of Arm, Shoulder and Hand questionnaire (QuickDASH) was administered as an online survey, and ipsi- and contralateral thumb motion was assessed. Results. A total of 67 patients completed the survey, of whom 63 (94%) had full interphalangeal joint extension or hyperextension. Severe metacarpophalangeal joint hyperextension (> 40°) was documented in 15 cases (22%). The median QuickDASH score was 0 (0 to 61), indicating excellent function at a median follow-up of 15 years (10 to 19). Overall satisfaction was high, with 56 patients (84%) reporting the maximal satisfaction score of 5. Among 37 patients who underwent surgery at age ≤ two years, 34 (92%) reported the largest satisfaction, whereas this was the case for 22 of 30 patients (73%) with surgery at aged > two years (p = 0.053). Notta’s nodule resolved in 49 patients (73%) at final follow-up. No residual triggering or
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
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). Methods. 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. Results. A total of 24 patients underwent guided growth and 19 underwent varus osteotomy, over a mean period of 3.3 years (95% confidence interval (CI) 2.8 to 3.8) and 5.2 years (95% CI 4.5 to 6.0), respectively. There were no differences in demographic and preoperative radiological data, except for a younger age at time of acetabuloplasty and larger ATD for the osteotomy group. The HSA did not differ at two years and the extended follow-up because of postoperative rebound in the osteotomy group. The NSA of the osteotomy group remained smaller postoperatively. There were no significant differences in the follow-up ATD, SA, and LCEA, except for a smaller two-year ATD of the osteotomy group. Seven patients (29.2%) in the guided growth group underwent
Aims. The aim of this study was to inform the epidemiology and treatment of slipped capital femoral epiphysis (SCFE). Methods. This was an anonymized comprehensive cohort study, with a nested consented cohort, following the the Idea, Development, Exploration, Assessment, Long-term study (IDEAL) framework. A total of 143 of 144 hospitals treating SCFE in Great Britain participated over an 18-month period. Patients were cross-checked against national administrative data and potential missing patients were identified. Clinician-reported outcomes were collected until two years. Patient-reported outcome measures (PROMs) were collected for a subset of participants. Results. A total of 486 children (513 hips) were newly affected, with a median of two patients (interquartile range 0 to 4) per hospital. The annual incidence was 3.34 (95% confidence interval (CI) 3.01 to 3.67) per 100,000 six- to 18-year-olds. Time to diagnosis in stable disease was increased in severe deformity. There was considerable variation in surgical strategy among those unable to walk at diagnosis (66 urgent surgery vs 43 surgery after interval delay), those with severe radiological deformity (34 fixation with deformity correction vs 36 without correction) and those with unaffected opposite hips (120 prophylactic fixation vs 286 no fixation). Independent risk factors for avascular necrosis (AVN) were the inability of the child to walk at presentation to hospital (adjusted odds ratio (aOR) 4.4 (95% CI 1.7 to 11.4)) and surgical technique of open reduction and internal fixation (aOR 7.5 (95% CI 2.4 to 23.2)). Overall, 33 unaffected untreated opposite hips (11.5%) were treated for SCFE by two-year follow-up. Age was the only independent risk factor for contralateral SCFE, with age under 12.5 years the optimal cut-off to define ‘at risk’. Of hips treated with prophylactic fixation, none had SCFE, though complications included femoral fracture, AVN, and

Aims. 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. Methods. 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. Results. In all, 39 children (52 feet) with a mean follow-up of 7.2 years (3.1 to 13.0) were included in the study. Resection of a duplicated great toe was performed in ten children, central polydactyly in four, and postaxial polydactyly in 26. The mean postoperative VAS (0.7; 0 to 7), ASK (93.7; 64.2 to 100), and AOFAS range (85.9 to 89.0) indicated excellent outcomes among this cohort and the PODCI global functioning scale (95.7; 75.5 to 100) was satisfactory. No significant differences were found regarding outcomes of pre- versus postaxial patients, nor radiological toe alignment between the operated and non-operated sides. Minor complications were observed in six children (15%). There were seven surgical revisions (18%), six of whom were in preaxial patients. In both groups, below the operation area, a reduced mean and maximum force was observed. Changes in the hindfoot region were detected based on the prolonged contact time and reduced force in the preaxial group. Conclusion. Excellent mid-term results can be expected after foot polydactyly resection in childhood. However, parents and those who care for these children need to be counselled regarding the higher risk of subsequent
Aims. The Fassier Duval (FD) rod is a third-generation telescopic implant for children with osteogenesis imperfecta (OI). Threaded fixation enables proximal insertion without opening the knee or ankle joint. We have reviewed our combined two-centre experience with this implant. Methods. In total, 34 children with a mean age of five years (1 to 14) with severe OI have undergone rodding of 72 lower limb long bones (27 tibial, 45 femoral) for recurrent fractures with progressive deformity despite optimized bone health and bisphosphonate therapy. Data were collected prospectively, with 1.5 to 11 years follow-up. Results. A total of 24 patients (33%) required exchange of implants (14 femora and ten tibiae) including 11 rods bending with refracture. Four (5%) required
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
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

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

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 reviewed the long-term radiological outcome,
complications and revision operations in 19 children with quadriplegic
cerebral palsy and hip dysplasia who underwent combined peri-iliac
osteotomy and femoral varus derotation osteotomy. They had a mean
age of 7.5 years (1.6 to 10.9) and comprised 22 hip dislocations
and subluxations. We also studied the outcome for the contralateral
hip. At a mean follow-up of 11.7 years (10 to 15.1) the Melbourne
cerebral palsy (CP) hip classification was grade 2 in 16 hips, grade
3 in five, and grade 5 in one. There were five complications seen
in four hips (21%, four patients), including one dislocation, one
subluxation, one coxa vara with adduction deformity, one subtrochanteric
fracture and one infection. A recurrent soft-tissue contracture occurred
in five hips and ten required
Current American Academy of Orthopaedic Surgeons (AAOS) guidelines for treating femoral fractures in children aged two to six years recommend early spica casting although some individuals have recommended intramedullary stabilization in this age group. The purpose of this study was to compare the treatment and family burden of care of spica casting and flexible intramedullary nailing in this age group. Patients aged two to six years old with acute, non-pathological femur fractures were prospectively enrolled at one of three tertiary children’s hospitals. Either early closed reduction with spica cast application or flexible intramedullary nailing was accomplished under general anaesthesia. The treatment method was selected after discussion of the options by the surgeon with the family. Data were prospectively collected on patient demographics, fracture characteristics, complications, pain medication, and union. The Impact on Family Scale was obtained at the six-week follow-up visit. In all, 75 patients were included in the study: 39 in the spica group and 36 in the nailing group. The mean age of the spica group was 2.71 (2.0 to 6.9) years and the mean age of the nailing group was 3.16 (2.0 to 6.9) years.Aims
Methods
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). We were able to follow-up on 775 patients (395 girls, 380 boys) who sustained a SCHF from 2004 to 2017. Patients completed questionnaires including the Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH; primary outcome), and the Pediatric Quality of Life Inventory (PedsQL).Aims

The purpose of this study was to compare the prevalence of hip displacement and dislocation in a total population of children with cerebral palsy (CP) in Scotland before and after the initiation of a hip surveillance programme. A total of 2,155 children with CP are registered in the Cerebral Palsy Integrated Pathway Scotland (CPIPS) surveillance programme, which began in 2013. Physical examination and hip radiological data are collected according to nationally agreed protocols.Aims
Patients
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
The aim of this study was to compare the surgical and quality-of-life outcomes of children with skeletal dysplasia to those in children with idiopathic early-onset scoliosis (EOS) undergoing growth-friendly management. A retrospective review of two prospective multicentre EOS databases identified 33 children with skeletal dysplasia and EOS (major curve ≥ 30°) who were treated with growth-friendly instrumentation at younger than ten years of age, had a minimum two years of postoperative follow-up, and had undergone three or more lengthening procedures. From the same registries, 33 matched controls with idiopathic EOS were identified. A total of 20 children in both groups were treated with growing rods and 13 children were treated with vertical expandable prosthetic titanium rib (VEPTR) instrumentation.Aims
Patients and Methods
Displaced fractures of the lateral condyle of the humerus are
frequently managed surgically with the aim of avoiding nonunion,
malunion, disturbances of growth and later arthritis. The ideal
method of fixation is however not known, and treatment varies between
surgeons and hospitals. The aim of this study was to compare the
outcome of two well-established forms of surgical treatment, Kirschner
wire (K-wire) and screw fixation. A retrospective cohort study of children who underwent surgical
treatment for a fracture of the lateral condyle of the humerus between
January 2005 and December 2014 at two centres was undertaken. Pre,
intraoperative and postoperative characteristics were evaluated. A total of 336 children were included in the study. Their mean
age at the time of injury was 5.8 years (0 to 15) with a male:female
patient ratio of 3:2. A total of 243 (72%) had a Milch II fracture
and the fracture was displaced by > 2 mm in 228 (68%). In all, 235
patients underwent K-wire fixation and 101 had screw fixation. Aims
Patients and Methods
Extendible endoprostheses have been available for more than 30
years and have become more sophisticated with time. The latest generation
is ‘non-invasive’ and can be lengthened with an external magnetic
force. Early results have shown a worryingly high rate of complications
such as infection. This study investigates the incidence of complications
and the need for further surgery in a cohort of patients with a
non-invasive growing endoprosthesis. Between 2003 and June 2014, 50 children (51 prostheses) had a
non-invasive growing prosthesis implanted for a primary bone sarcoma.
The minimum follow-up was 24 months for those who survived. Their
mean age was 10.4 years (6 to 14). The incidence of complications
and further surgery was documented.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. 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

Pelvic obliquity is a common finding in adolescents
with cerebral palsy, however, there is little agreement on its measurement
or relationship with hip development at different gross motor function
classification system (GMFCS) levels. The purpose of this investigation was to study these issues in
a large, population-based cohort of adolescents with cerebral palsy
at transition into adult services. The cohort were a subset of a three year birth cohort (n = 98,
65M: 33F, with a mean age of 18.8 years (14.8 to 23.63) at their
last radiological review) with the common features of a migration
percentage greater than 30% and a history of adductor release surgery. Different radiological methods of measuring pelvic obliquity
were investigated in 40 patients and the angle between the acetabular
tear drops (ITDL) and the horizontal reference frame of the radiograph
was found to be reliable, with good face validity. This was selected
for further study in all 98 patients. The median pelvic obliquity was 4° (interquartile range 2° to
8°). There was a strong correlation between hip morphology and the
presence of pelvic obliquity (effect of ITDL on Sharpe’s angle in
the higher hip; rho 7.20 (5% confidence interval 5.59 to 8.81, p
<
0.001). This was particularly true in non-ambulant adolescents
(GMFCS IV and V) with severe pelvic obliquity, but was also easily
detectable and clinically relevant in ambulant adolescents with mild
pelvic obliquity. The identification of pelvic obliquity and its management deserves
closer scrutiny in children and adolescents with cerebral palsy. Cite this article:
Proximal femoral resection (PFR) is a proven
pain-relieving procedure for the management of patients with severe cerebral
palsy and a painful displaced hip. Previous authors have recommended
post-operative traction or immobilisation to prevent a recurrence
of pain due to proximal migration of the femoral stump. We present
a series of 79 PFRs in 63 patients, age 14.7 years (10 to 26; 35
male, 28 female), none of whom had post-operative traction or immobilisation. A total of 71 hips (89.6%) were reported to be pain free or to
have mild pain following surgery. Four children underwent further
resection for persistent pain; of these, three had successful resolution
of pain and one had no benefit. A total of 16 hips (20.2%) showed
radiographic evidence of heterotopic ossification, all of which
had formed within one year of surgery. Four patients had a wound
infection, one of which needed debridement; all recovered fully.
A total of 59 patients (94%) reported improvements in seating and
hygiene. The results are as good as or better than the historical results
of using traction or immobilisation. We recommend that following
PFR, children can be managed without traction or immobilisation,
and can be discharged earlier and with fewer complications. However,
care should be taken with severely dystonic patients, in whom more
extensive femoral resection should be considered in combination
with management of the increased tone. 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 report the results of Vulpius transverse gastrocsoleus
recession for equinus gait in 26 children with cerebral palsy (CP),
using the Gait Profile Score (GPS), Gait Variable Scores (GVS) and
movement analysis profile. All children had an equinus deformity
on physical examination and equinus gait on three-dimensional gait
analysis prior to surgery. The pre-operative and post-operative
GPS and GVS were statistically analysed. There were 20 boys and
6 girls in the study cohort with a mean age at surgery of 9.2 years
(5.1 to 17.7) and 11.5 years (7.3 to 20.8) at follow-up. Of the
26 children, 14 had spastic diplegia and 12 spastic hemiplegia.
Gait function improved for the cohort, confirmed by a decrease in
mean GPS from 13.4° pre-operatively to 9.0° final review (p <
0.001). The change was 2.8 times the minimal clinically important
difference (MCID). Thus the improvements in gait were both clinically and
statistically significant. The transverse gastrocsoleus recession
described by Vulpius is an effective procedure for equinus gait
in selected children with CP, when there is a fixed contracture
of the gastrocnemius and soleus muscles. 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:
The aim of this study was to determine whether
an osteoplasty of the femoral neck performed at the same time as an
intertrochanteric Imhäuser osteotomy led to an improved functional
outcome or increased morbidity. A total of 20 hips in 19 patients
(12 left, 8 right, 13 male, 6 female), who underwent an Imhäuser
intertrochanteric osteotomy following a slipped capital femoral
epiphysis were assessed over an eight-year period. A total of 13
hips in 13 patients had an osteoplasty of the femoral neck at the
same time. The remaining six patients (seven hips) had intertrochanteric
osteotomy alone. The mean age was 15.3 years (13 to 20) with a mean
follow-up of 57.8 months (15 to 117); 19 of the slips were severe
(Southwick grade III) and one was moderate (grade II), with a mean
slip angle of 65.3° (50° to 80°); 17 of the slips were stable and
three unstable at initial presentation. The mean Non-Arthritic Hip Scores
(NAHS) in patients who underwent osteoplasty was 91.7 (76.3 to 100)
and the mean NAHS in patients who did not undergo osteoplasty was
76.6 (41.3 to 100) (p = 0.056). Two patients required a subsequent
arthroplasty and neither of these patients had an osteoplasty. No
hips developed osteonecrosis or chondrolysis, and there was no increase
in complications related to the osteoplasty. We recommend that for
patients with a slipped upper femoral epiphysis undergoing an intertrochanteric
osteotomy, the addition of an osteoplasty of the femoral neck should
be considered. Cite this article:
The medial approach for the treatment of children
with developmental dysplasia of the hip (DDH) in whom closed reduction
has failed requires minimal access with negligible blood loss. In
the United Kingdom, there is a preference for these children to
be treated using an anterolateral approach after the appearance
of the ossific nucleus. In this study we compared these two protocols,
primarily for the risk of osteonecrosis. Data were gathered prospectively for protocols involving the
medial approach (26 hips in 22 children) and the anterolateral approach
(22 hips in 21 children) in children aged <
24 months at the
time of surgery. Osteonecrosis of the femoral head was assessed
with validated scores. The acetabular index (AI) and centre–edge
angle (CEA) were also measured. The mean age of the children at the time of surgery was 11 months
(3 to 24) for the medial approach group and 18 months (12 to 24)
for the anterolateral group, and the combined mean follow-up was
70 months (26 to 228). Osteonecrosis of the femoral head was evident
or asphericity predicted in three of 26 hips (12%) in the medial approach
group and four of 22 (18%) in the anterolateral group (p = 0.52).
The mean improvement in AI was 8.8° (4° to 12°) and 7.9° (6° to
10°), respectively, at two years post-operatively (p = 0.18). There
was no significant difference in CEA values of affected hips between
the two groups. Children treated using an early medial approach did not have
a higher risk of developing osteonecrosis at early to mid-term follow-up
than those treated using a delayed anterolateral approach. The rates
of acetabular remodelling were similar for both protocols. Cite this article:
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.
The results of further soft-tissue release of 79 feet in 60 children with recurrent idiopathic congenital talipes equinovarus were evaluated. The mean age of the children at the time of re-operation was 5.8 years (15 months to 14.5 years). Soft-tissue release was performed in all 79 feet and combined with distal calcaneal excision in 52 feet. The mean follow-up was 12 years (4 to 32). At the latest follow-up the result was excellent or good in 61 feet (77%) according to the Ghanem and Seringe scoring system. The results was considered as fair in 14 feet (18%), all of whom had functional problems and eight had anatomical abnormalities. Four feet (5%) were graded as poor on both functional and anatomical grounds. The results were independent of the age at which revision was undertaken.
Fractures of the femoral neck in children are
rare, high-energy injuries with high complication rates. Their treatment has
become more interventional but evidence of the efficacy of such
measures is limited. We performed a systematic review of studies
examining different types of treatment and their outcomes, including
avascular necrosis (AVN), nonunion, coxa vara, premature physeal
closure (PPC), and Ratliff’s clinical criteria. A total of 30 studies
were included, comprising 935 patients. Operative treatment and
open reduction were associated with higher rates of AVN. Delbet
types I and II fractures were most likely to undergo open reduction
and internal fixation. Coxa vara was reduced in the operative group,
whereas nonunion and PPC were not related to surgical intervention. Nonunion
and coxa vara were unaffected by the method of reduction. Capsular
decompression had no effect on AVN. Although surgery allows a more
anatomical union, it is uncertain whether operative treatment or
the type of reduction affects the rate of AVN, nonunion or PPC,
because more severe fractures were operated upon more frequently.
A delay in treatment beyond 24 hours was associated with a higher
incidence of AVN. 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.
Most cases of club foot (congenital talipes equinovarus) respond to non-operative treatment but resistant cases may need surgery. It is broadly accepted that lengthening of tendo Achillis, the tendon of tibialis posterior and capsulotomy of the ankle and subtalar joints are necessary during surgical release, but there is no consensus as to whether lengthening of the tendons of flexor hallucis longus and flexor digitorum longus is required. We randomised 13 children with severe bilateral club foot deformities to undergo lengthening of the flexor hallucis longus and flexor digitorum longus tendons on one side and simple decompression on the other. We found no difference in the deformities of the toes between the lengthened and non-lengthened sides at a mean follow-up of four years (2 to 6). We conclude that routine lengthening of the tendons of flexor hallucis longus and flexor digitorum longus during soft-tissue surgery for resistant club foot is not necessary.
Treatment by continuous passive movement at home is an alternative to immobilisation in a cast after surgery for club foot. Compliance with the recommended treatment, of at least four hours daily, is unknown. The duration of treatment was measured in 24 of 27 consecutive children with a mean age of 24 months (5 to 75) following posteromedial release for idiopathic club foot. Only 21% (5) of the children used the continuous passive movement machine as recommended. The mean duration of treatment at home each day was 126 minutes (11 to 496). The mean range of movement for plantar flexion improved from 15.2° (10.0° to 20.6°) to 18.7° (10.0° to 33.0°) and for dorsiflexion from 12.3° (7.4° to 19.4°) to 18.9° (10.0° to 24.1°) (both, p = 0.0001) when the first third of therapy was compared with the last third. A low level of patient compliance must be considered when the outcome after treatment at home is interpreted.
We reviewed retrospectively 45 patients (46 procedures) with bladder exstrophy treated by bilateral oblique pelvic osteotomy in conjunction with genitourinary repair. The operative technique and post-operative management with or without external fixation are described. A total of 21 patients attended a special follow-up clinic and 24 were interviewed by telephone. The mean follow-up time was 57 months (24 to 108). Of the 45 patients, 42 reported no pain or functional disability, although six had a waddling gait and two had marked external rotation of the hip. Complications included three cases of infection and loosening of the external fixator requiring early removal with no deleterious effect. Mid-line closure failed in one neonate managed in plaster. This patient underwent a successful revision procedure several months later using repeat osteotomies and external fixation. The percentage pubic approximation was measured on anteroposterior radiographs pre-operatively, post-operatively and at final follow-up. The mean approximation was 37% (12% to 76%). It varied markedly with age and was better when external fixation was used. The wide range reflects the inability of the anterior segment to develop naturally in spite of close approximation at operation. We conclude that bilateral oblique pelvic osteotomy with or without external fixation is useful in the management of difficult primary closure in bladder exstrophy, failed primary closure and secondary reconstruction.
Subluxation of the hip is common in patients with intermediate spinal muscular atrophy. This retrospective study aimed to investigate the influence of surgery on pain and function, as well as the natural history of subluxed hips which were treated conservatively. Thirty patients were assessed clinically and radiologically. Of the nine who underwent surgery only one reported satisfaction and four had recurrent subluxation. Of the 21 patients who had no surgery, 18 had subluxation at the latest follow-up, but only one reported pain in the hip. We conclude that surgery for subluxation of the hip in these patients is not justified.
