Purpose:. To examine the feasibility of surgical outcome measures for a children's orthopaedic surgeon when compared with other specialties. Methods & Results:. Details of procedure codes for 2726 inpatient episodes were used to examine the distribution of procedures and the breadth of diagnoses dealt with by a variety of orthopaedic sub-specialists. The author's practice included 199 surgical cases and was compared with two arthroplasty surgeons (n=971); a spinal surgeon (n=256); a foot and ankle surgeon (n=341) and an upper limb surgeon (n=393). Arthroplasty surgeons can report 50% of their outcomes as primary knee or hip replacements the index procedure for the author is metalwork removal (14.5%). My upper limb colleague could be judged on 25% of his cases (carpal tunnel decompression) and my spinal surgical colleague on 20% of his cases (primary posterior decompression of spinal cord). Only my foot and ankle colleague compared in terms of diversity with 9% of his cases consisting of first metatarsal osteotomy and the next 9% consisting of 1st MTPJ arthrodesis. The proportion of multiple procedures also varies between sub-specialists with 66% of my cases being multiple compared with 38% for the arthroplasty surgeons and 42% for the upper limb surgeons. Foot and ankle has a high rate of multiple procedures (62%) and the spinal surgeons code different procedures at each level in the spine giving the high rates of multiple procedures. Conclusion:. Outcome measures in
This 20-year prospective longitudinal observational study aims to determine the incidence of pathological developmental dysplasia of the hip (DDH) in children referred with clicky hips and define the risk posed to inform neonatal hip screening programmes including the role of ultrasound. 355 children from 1997 to 2016 were referred with clicky hips to our “one stop” paediatric hip clinic under the local neonatal hip screening programme. Hips were assessed clinically for instability and by ultrasound using a simplified Graf classification. Dislocated or dislocatable hips were classed as Graf type IV.Purpose

This study aims to report the radiological corrections achieved and complication profile of Peri-Acetabular Osteotomy (PAO) undertaken through the minimally invasive approach. 106 PAOs were performed in 103 patients, by senior author, using a minimally invasive approach from 2007 to 2015. Pre- and post-operative radiographs were reviewed and the degree of acetabular re-orientation was analysed. Case notes were examined retrospectively to identify haemoglobin levels and complications across two sites.Purpose

The treatment of developmental dysplasia of the hip (DDH) in children remains controversial, we describe the clinical and radiological outcomes of 47 hips in 43 children treated with open surgery by one surgeon between 2004 and 2008 for DDH. The mean age at operation was 25 months (5 to 113) with a mean follow up of 89 months (22 to 169). 46 hips had an anterior open reduction, 1 had a medial approach performed and 16 had anterior open reductions only. 5 of the primary operations also had a pelvic osteotomy, 7 had a femoral osteotomy and 18 had a combined femoral and pelvic osteotomy. 7 (15%) of the hips required a second operation for dislocation, subluxation or dysplasia. At the latest follow up 40 of the 45 hips where Severin grades were recordable (89%) were graded as excellent or good, Severin class I or II. Clinically significant AVN (grade II to III according to the Kalamchi and MacEwen classification) was seen in 5 (11%) of the hips. We found a pelvic osteotomy to be a risk factor for AVN (p 0.02) and age at operation to be a risk factor for poor morphology at final follow up (p 0.03). We proceed to open surgery in patients over 12 months old or those with failed closed reduction. Over 18 months old a pelvic osteotomy should be performed in selective cases depending on intra-operative stability, but we will now consider doing this as a staged procedure and delaying the osteotomy for a period of time after open reduction to reduce the risk of AVN. We will also have a much lower threshold for performing a femoral shortening osteotomy in these patients as open reduction with Salters osteotomy alone tended to have a poorer outcome.
The aim of our survey was to study the current practice to manage DDH in UK by the members of the British Society for Children's Orthopaedic Surgery. An online questionnaire link to ask about the management of DDH was emailed to 204 members of the British Society for Children's Orthopaedic Surgery. The response rate was 39%. 73% respondents have a local screening programme, 19% screen only high risk children and 8% had no screening programme. Pavlik harness was used by 87% respondents for Graf Type 2, 96% for Graf type 3 and 90% for Graf type 4. 14% respondents will only observe for Graf Type 2. 36% respondents will follow up children every week, 45% every 2 weeks, 3% every 3 weeks, 9% every 4 weeks, 4% every 6 weeks and 3% will decide the follow up according to severity of DDH and treatment.1.3% respondents will follow up these patients for 6 months, 13% for 12 months, 10.5% each for 24 months, 36 months, 48 months and 50% until skeletal maturity. After the failure of initial splintage, 7% respondents will consider surgery immediately, 13.5% at 3 months, 36.5% at 6 months, 4% at 9 months, 28% at 12 months, 5.4% according to HIP-OP Trial and 5.6% according to the situation. There was no consensus about the treatment of DDH. 73% respondents have a local screening programme. The most common splintage method used was Pavlik harness. 45% respondents will follow up children every 2 weeks following the start of treatment. 50% respondents will follow up these patients until skeletal maturity. 36% respondents will consider surgery at 6 months following the failure of splintage. This survey highlights the fact that the management of DDH is an art based on the scientific evidence, parent's choice and personal expertise.
Originally used for correction of angular malalignment, 2 hole plate epiphyseodesis has recently gained popularity in paediatric orthopaedic practice for the correction of leg length discrepancy. In this study we aim to assess the efficiency of guided growth plates in correcting leg length discrepancy Thirty-three children treated for leg length discrepancy with guided growth plates (“8-Plate”, Orthofix, Inc and “I-Plate”, Orthopediatrics) in a tertiary referral centre were retrospectively analysed. Medial and Lateral plates were inserted for symmetrical growth reduction and patients were followed up with clinical and radiological assessment. Thirty patients had distal femoral epiphyseodesis and three had proximal tibial epiphyseodesis. Leg lengths and individual bone lengths were measured from pre and post – operative radiographs. The angle between the screws was measured from radiographs taken intra operatively and at the time of final follow up to assess screw divergence with growth. Efficiency was calculated as the ratio of growth inhibition achieved to the projected discrepancy at maturity if left untreated. At a mean follow up of 17 months (4–30 m) leg length discrepancy improved from a mean of 30 mm (50–15mm) to 13 mm (2.5–39mm) (p < 0.01). The angle between screws increased from 6 degrees to 26 degrees over the follow up period. Efficiency was found to be 66%. There were 5 patients with angular deformity who needed plate removal and 2 patients developed superficial infection that responded to oral antibiotics. Epiphyseodesis using guided growth plates is an effective way to correct leg length discrepancy as it is a reversible procedure. Patients undergoing this treatment should be kept under close follow up to prevent development of angular malalignment. Inserting the screws in a divergent fashion at the outset may increase the effectiveness of this procedure.
This pilot study aims to investigate the utility and feasibility of a unique upright MR scan for imaging hips affected by Legg-Calve-Perthes Disease (LCPD) with patient standing up, in comparison to the standard supine scans. Protocol development using this unique upright MRI included healthy adult and child volunteers. Optimum patient positioning in a comparable way between supine to standing was assessed. The balance between shorter scan time (to what a child can tolerate) and longer scan time (for better image acquisition). The study protocol has begun in 2 children with LCPD. Patient recruitment continues. Early results indicate a dynamic deformity of the femoral head in early stage LCP disease. Femoral epiphysis height decreased on standing (7.8 to 6.8mm), width increased on standing (16.6 to 20.9mm) and lateral extrusion increased (3.5 to 4.1mm). Overall epiphyseal shape changed from trapezoidal (LCP femoral head when supine) to flattened triangular (LCP femoral head when standing). Differences were thus demonstrated in all parameters of bony epiphyseal height, width, extrusion and shape of a femoral head with LCP Disease when the child stood and loaded the affected hip. Satisfactory image acquisition was possible with Coronal T1 GFE sequences, with both hips in the Field of View. 2.5min scans were performed with the child standing first, then supine. Hip position was comparable when standing and supine. Longer scans were not tolerated by younger children, more so those with LCP disease. To our knowledge this is the first reported use of standing MRI in LCPD. A dynamic deformity has been demonstrated, with flattening, widening and worsened lateral extrusion when the child is standing compared to supine. This proof of concept investigation demonstrates the feasibility of upright MRI scanning and may demonstrate previously undetected deformity.
This study sought to determine the genetic contribution of Perthes' disease, using the world's largest twin-registry. We extracted all twin pairs from the Danish Twin Registry (DTR) in which at least one individual had Perthes' Disease. The DTR captures every twin pair born alive in Denmark. Those with Perthes' disease were identified using health record linkage to the Danish Morbidity Record. Probandwise concordance was calculated to describe the likelihood that any given individual had LCPD if their co-twin was also diagnosed. There were 81 twin pairs; 10 monozygotic (MZ), 51 dizygotic (DZ), and 20 unclassified (UZ). There was no association between birth weight and being the affected co-twin. Four pairs (two dizygotic and two unclassified) were concordant for LCPD, which is greater than would be expected assuming no familial aggregation. There were no concordant MZ twin pairs. The overall probandwise concordance was 0.09 (95% CI 0.01–0.18): 0.00 for the MZ, 0.08 (95% CI 0.00–0.18) for the DZ, and 0.18 (95% 0.00–0.40) for the UZ twin pairs. This study found evidence of familial clustering in LCPD but did not demonstrate a genetic component. The absolute risk that a co-twin of an affected individual will develop LCPD is low, even in the case of MZ twin pairs.
We present the long term outcome from children with Legg-Calves-Perthes (LCPD) treated at our unit. Patients treated for LCPD were identified retrospectively from an orthopaedic database between 1990 and 2005. Patient demographics, clinical examination, treatment and Herring classification were recorded at initial presentation and treatment. Long-term clinical and radiological follow-up was also recorded. 85 patients were identified and 4 excluded due to insufficient data giving a total of 81 patients. Of these, 58 were male and 23 female. Average age range at presentation was 6.5 years (range 1.5–14 yrs). The side affected was 34 right, 35 left, 24 bilateral giving 93 hips in total. Time between presentation and diagnosis averaged 4.7 months (range 0–48 months). In patients with recorded clinical examination 87% had reduced abduction and 88% reduced internal rotation. Treatment was largely conservative with 12 hips (13%) undergoing surgery within the first 4 years of diagnosis. Radiographs were available for 71 hips. Herring classification was A-12, B-22, C-37. Long term follow up averaged 16 years (range 10–25 yrs). Stulberg grading was available in 67 hips; Grade I 13, Grade II 21, Grade III 19, Grade IV 18 and Grade V 6. There were ongoing issues (mostly pain) in 18 hips, 5 of which required a subsequent operation. No correlation was found between abduction and Stulberg grade (p-value = 0.7). A correlation was found between delay in diagnosis of ≥6 months and the need for a subsequent operation (p-value = 0.0408). The overall trend as expected showed that a better Herring classification generally led to a more favourable Stulberg classification. Range of motion was not predictive for Stulberg grade. The need for further surgical intervention for symptoms at long term follow up was 0.05%.
To evaluate the safety and efficacy of treating patients with Graf IIa developmental hip dysplasia. The management of the developmentally immature Graf Type IIa dysplastic hip is controversial. Some authors advocate early treatment with an abduction harness whilst others adopt watchful waiting. At our institution selective sonographic assessment for developmental dysplasia of the hip (DDH) was established in 1997 with prospective data collection. All infants diagnosed with Graf Type IIa hip(s) were treated with either a Pavlik harness or double nappies, with clinical and sonographic follow up until normalisation. Pelvic radiographs were routinely performed at 8 and 18 months follow up for assessment of residual dysplasia and/or complications of treatment. We evaluated the safety and efficacy of all treated patients between 2005 and 2013. Complete clinical and radiological follow up (mean 2.1 years, 0.7–6.5) was available for 103 of 118 infants. 69 were treated with a Pavlik harness and 49 with double nappies. The chosen treatment was successful in 110 hips with no documented complications, well developed ossific nuclei on follow up radiographs, and no further treatments undertaken. In the double nappy group 4 infants deteriorated sonographically so were changed to a Pavlik harness with subsequent normalisation and successful treatment. 3 patients required VDRO at age 18 months (17–20) and 1 patient required closed reduction and spica cast treatment at age 11 months. No further complications arose in this group. The 15 patients lost to follow up had successful initial treatment but failed to attend for radiographic review. Both Pavlik harness and double nappies are safe treatment modalities for Type IIa hip dysplasia. However, sonographic deterioration was observed in both groups with surgical intervention required in the minority, supporting the ongoing treatment of these immature hips.
The aim of this study was determine if the detection of pathology in children with a limp can be optimised by screening with blood tests for raised inflammatory markers. The entry criteria for the study were children (0–15 years) presenting to our hospital Emergency Department from 2012–2015 with a non-traumatic limp or pseudoparalysis of a limb, and no sign of fracture or malignancy on plain radiographs. ESR and CRP blood tests were performed along with other standard investigations. Children with ESR or CRP over 10 underwent MRI scan of their area of pain or tendernesss, with those under 7 years old having general anaesthetic. MRI provided the diagnosis in cases of osteomyelitis, pyomyositis, fasciitis, cellulitis, discitis, as well as non-infective conditions such as malignancy and fracture not visible on plain radiographs. Where a joint effusion was present, the diagnosis of septic arthritis was made from organisms cultured following surgical drainage, or high white cell count in joint fluid if no organisms were cultured. The study was completed once data from 100 consecutive children was available. 64% of children had an infective cause for their symptoms (osteomyelitis, septic arthritis, pyomyositis, fasciitis, cellulitis or discitis). A further 11% had positive findings on MRI from non-infective causes (juvenile idiopathic arthritis, cancer, or occult fracture). The remaining 25% had either a normal scan, or transient synovitis. ESR was a more sensitive marker than CRP, since ESR was raised in 97% of those with abnormal scans, but CRP in only 70%. There were no complications from any of the GA MRI scans. Conclusion: This shows that MRI imaging of all children with a limp and either raised ESR or CRP is a sensitive method to minimise the chance of missing important pathology in this group, and is not wasteful of MRI resources.
The aim was to determine reliability in treatment threshold based on USS angular measurements between observers involved in the DDH hip screening programme at the NOC and assess the effect of image orientation on the accuracy of these measurements. 3 independent observers measured alpha and beta angles on bilateral hips in 10 consecutive patients seen in the DDH hip screening clinic. All scans were performed by a single radiographer and observers used the same set of USS images for a given patient. Each observer measured alpha and beta angles a total of 4 times: conventional ultrasound image projection (with the ilium horizontal) (round 1), Graf's anatomical projection (round 2), and both techniques repeated 1 month later (round 3 and 4 respectively) to assess intra-observer reliability. To determine its effect on treatment threshold taking into account alpha and beta angles and patient's age, the consistency between observers' management recommendations was evaluated for each round. Possible outcomes were: 1) patient discharged, 2) no treatment needed yet, but follow-up required, 3) start treatment. Intra-observer reliability for conventional projection was moderate (Kappa 0.58), and improved for anatomical projection (Kappa 0.65). Inter-observer reliability, as a surrogate measure of consistency in management recommendations between observers, ranged from fair to moderate across the 4 rounds (Kappa 0.30 – 0.50). However, contrary to previous recommendations, reliability was better with conventional projection (Kappa 0.41 (95% CI 0.11–0.72)) compared to anatomical projection (Kappa 0.36 (95% CI −0.01–0.73)). The overall agreement in management recommendations, pooling all results across 4 rounds, was 51.3% (Kappa 0.39 (95%CI 0.15–0.63)). This audit supports the argument that anatomical image projection improves intra-observer consistency. However, as with all USS measurements, angular measurements were highly user dependent and treatment threshold based on USS may not be as consistent as anticipated.
The aim was to assess the value of the GP 6–8 week hip examination. In a 15-year prospective observational longitudinal cohort study, every infant referred by the GP with suspected pathological developmental dysplasia of the hip (DDH) had their hip joints clinically and sonographically examined in a specialist hip screening clinic. Graf Type IV and dislocated hips were classified as pathological. Screening failures were defined as those who had not been identified by the 6–8 week check and presented with late instability. Secondary univariate and multivariable analysis was performed to determine which clinical findings are predictive of instability. 64,518 infants underwent the 6–8 week GP check. Of 176 referrals, 5 had pathological hips. 13 screening failures, presented between the ages of 17 and 80 weeks. The 6–8 week check has a sensitivity of 28% and a specificity of 99.7%. Univariate analysis revealed positive Ortolani tests and patients referred as ‘unstable hip’ to be significant predictors of hip pathology. Clicky hips, asymmetric skin creases, and leg length inequality were not predictive of pathological hips. A multivariable model showed a positive Ortolani test to be the sole independent predictor of instability at 6–8 weeks. This is the first attempt to test the validity of the 6–8 week GP clinical hip check. A low rate of hip pathology was identified. The high rate of false negatives raises questions about the value of screening at this age. At 6–8 weeks, clinical signs of hip instability are unreliable as hips become irreducible and stiff. Based on our findings, we recommend that at 6–8 weeks, referrals are only made if the Ortolani test is positive. We advocate the reintroduction of the 8-month check, including an assessment for limited hip abduction, which may improve the detection rate of those missed by initial screening.
To evaluate effectiveness and safety of acute ulnar lengthening osteotomy in Madelung's deformity associated with Hereditary Multiple Exostoses (HME) Seventeen ulnas in 13 patients had acute ulnar lengthening for HME associated forearm deformity. Defined radiographic parameters were compared pre- and post-operatively using student's t-test; ulnar variance, carpal slip, radial bowing, radial articular angle. All complications were noted. Mean follow-up was 27 months (range 1.5 – 72months). An increase in ulna length by a mean of 15.4mm (range 4.5 – 29.3mm) was achieved acutely, corresponding to an increase of 9.3% of total ulnar length. Negative ulnar variance was improved from a pre-operative mean of 12.4mm (range 6.1–16.5mm) to a post-operative mean of 4.6mm (range 0–11.25mm) (p=<0.00001). Carpal slip was significantly improved by a mean of 2.2mm (p=0.02). No significant change in radial bowing (p=0.98) or radial articular angle (p=0.74) was observed. Inter-rater reliability was excellent (r=0.96, Pearson Correlation). Three patients required second procedures for recurrence of deformity at 18 months – 6 years following their primary operation. There were no incidences of compartment syndrome, neurovascular injury nor infection. One ulna fractured intra-operatively requiring a longer plate. One patient had a non union which united on revision surgery. Significant radiographic improvements in forearm and wrist alignment were seen with acute ulnar lengthening. The procedure is safe, with no compartment syndrome nor neurovascular injury and low complications rate. Recurrence rates in the skeletally immature patients are comparable to that reported with gradual lengthening. Acute ulnar lengthening for forearm deformity associated with HME has been demonstrated to be a safe, reproducible and effective surgical procedure.
To evaluate the outcome of combined tibialis anterior tendon shortening (TATS) and calf muscle-tendon lengthening (CMTL) in spastic equinus. Prospectively collected data was analysed in 26 patients with hemiplegic (n=13) and diplegic (n=13) cerebral palsy (CP) (GMFCS level I or II, 14 males, 12 females, age range 10–35 years; mean 16.8 years). None had received botulinum toxin A injections or surgery in the preceding six and 12 months respectively. All patients had pre-operative 3D gait analysis and a further analysis at a mean of 17.1 months (± 5.6months) after surgery. None was lost to follow-up. Twenty-eight combined TATS and CMTL were undertaken and 19 nineteen patients had additional synchronous multilevel surgery. At follow-up 79% of patients had improved foot positioning at initial contact. Statistically significant improvements were seen in the Movement Analysis Profile for ankle dorsi-/plantarflexion (4.25, p=0.032), maximum ankle dorsiflexion during swing phase (11.68°, p<0.001), and Edinburgh Visual Gait Score (EVGS) (4.85, p=0.014). Diplegic patients had a greater improvement in the EVGS than hemiplegics (6.27 -vs- 2.21, p = 0.024). The originators of combined TATS and CMTL showed that it improved foot positioning during gait. The present study has independently confirmed favourable outcomes in a similar patient population and added additional outcome measures, the EVGS, foot positioning at initial contact, and maximum ankle dorsiflexion during swing phase. Study limitations include short term follow-up in a heterogeneous population and that 19 patients had additional surgery. However, distinguishing between the natural history of CP and interventions and isolating the effects of one intervention from others in multilevel surgery are well recognised difficulties in cohort studies in CP. TATS combined with CMTL is a recommended option for spastic equinus in ambulatory patients with CP.
Due to abnormal neuromuscular development, functional capability in children with cerebral palsy is often severely compromised. Single event multi-level surgery (SEMLS) is the gold standard surgical treatment for patients with cerebral palsy. It has been demonstrated to improve gait, however, how standing posture is affected is unknown. The aim was to investigate the effect of SEMLS in patients with spastic cerebral palsy on walking and standing posture using 3D gait analysis. Participants were identified from the One Small Step Gait Laboratory database. Standardised 3D-Gait analysis was performed within 2 years pre- and post-SEMLS. Gait abnormality was measured using the Gait Profile Score (GPS) index; standing abnormality was measured using the newly-developed Standing Profile Score (SPS) index. A control group (n=20) of age/sex-matched CP patients who did not undergo surgery were also assessed. 104 patients (73 boys, 31 girls) with spastic cerebral palsy underwent SEMLS with appropriate pre- and post-gait analyses (2000–2015). 91 patients had bilateral limb involvement, 14 had unilateral limb involvement. Average age at surgery was 10.38 years (range 4.85–15.60 years). A total of 341 procedures were performed, with hamstring and gastrocnemius lengthening representing approximately 65% of this. There was a 20% mean improvement in walking (GPS reduced 2.4°, p<0.001) and standing (SPS reduced 3.4°, p<0.001) following SEMLS. No improvement was noted in the control group. Significant correlations were observed between the changes in SPS and GPS following surgery (r2, p<0.001). Patients with poorer pre-operative standing posture (SPS) reported the most significant improvement following surgery. We confirmed improvement in walking following SEMLS using the Gait Profile Score (GPS). This is the first paper to report that standing posture is also improved following surgery using a novel index, the Standing Posture Score (SPS). SPS could be adopted as a tool to assess functional capability and predict post-operative changes.
The aim was to examine the descriptive epidemiology of Slipped Capital Femoral Epiphysis, with respect to geography and time. We extracted all children with a diagnosis of Slipped Capital Femoral Epiphysis from the Clinical Practice Research Database between 1990 and 2014 (24 years). CPRD is the world's largest database of primary care, which encompasses 8% of the UK population. CPRD was linked to Hospital Episode Statistics, and a validation algorithm applied to maximise sensitivity and specificity of the cases finding methodology. Poisson confidence intervals were calculated, and poison regression used. 596 cases of SCFE were identified. The internal validation algorithm supported a SCFE diagnosis in 88% cases. The age and sex distribution of cases mirrored that in the literature, offering external validity to the cases identified. There was no significant change in the incidence of SCFE over the 24-year study period, with the overall incidence being 4.8 cases per 100,00 0–16 year olds. There was no significant geographic variation in SCFE within the UK. There was a positive association with rising socioeconomic deprivation (p<0.01). There was no seasonal variation in presentation. This study found no evidence to support the common belief that SCFE incidence is increasing, and for the first time demonstrated an association with socioeconomic deprivation. The results are important for considering the feasibility of intervention studies, and offer insights into the disease aetiology.
The study describes a technique of tibial autograft to augment posterior instrumented spinal fusion in a population of paediatric patients with severe idiopathic, neuromuscular or syndromic scoliosis who are at a higher risk of postoperative pseudarthrosis and reports patient outcomes in terms of union rate, donor site morbidity and cost. Patients were identified from a review of waiting list and operating room records between 2007–2014. Surgery was performed by the senior author. Information on patient demographics, underlying diagnosis, age at surgery, revision surgery and length of follow-up was obtained from clinic notes. Parents of children were followed up with a structured telephone questionnaire regarding ambulatory status, post-operative pain, infection, further surgery and general satisfaction. Four hundred and nine patients underwent posterior instrumented spinal fusion, during the study period. Forty-two patients’ fusions were augmented with tibial graft, 40 of whom participated in the study. There were no cases of donor site infection, compartment syndrome, tibial fracture or perioperative mortality. In 85% of cases leg pain had resolved within 6 weeks, and 100% within 6 months of surgery. There were 6 cases of revision spinal surgery, 3 for infection, 2 for sacroiliac screw removal and 1 for sacroiliac screw revision. There were no clinical cases of spinal pseudarthrosis in this series. All parents were satisfied by the clinical outcome of both the tibial and spinal surgeries. Spinal fusion utilising tibial autograft is advocated as a simple, safe and cost-effective method of providing significant structural autograft to support fusion for a population of patients with high risk of junctional pseudarthrosis. With the exception of transient post-operative pain, the procedure was without any serious donor site morbidity. The outcomes of this study were as expected and in keeping with previous reports.
The aim of the study was to review the effectiveness of rigid IM nailing in stabilisation and deformity correction of lower limb long bones in adolescents with metabolic bone disease which to our knowledge has not been studied before. Medical records and radiographs were retrospectively reviewed looking at indications, deformity correction, number of osteotomies-if needed, bone healing, time to healing and incidence of complications. Between Aug 2010 and Mar 2015 fifteen patients (24 segments) had rigid IM nailing. Ten patients had Osteogenesis Imperfecta, four with McCune Albright syndrome and one with hypophosphatemic rickets. 22 femora and two tibiae were IM nailed. The mean age of the patients was 13.1 (9.6–16.75 years). Eleven out 24 segments were previously rodded. Eight segments were for acute fractures. 13 bones had significant deformities requiring corrective osteotomies. One patient had previous fracture non union. All patients were allowed to partial weight bear immediately postoperatively and were fully mobile six weeks following surgery. Mean follow up was 24 months (3–51 months) post-operatively. All deformities were corrected. All fractures and osteotomies radiologically united. Mean radiological union time was 5.5 months (6 weeks – 11 months). Patients with acute fractures had mean radiological union time of 4 months. Patients who had osteotomies had a mean radiological union time of 7.1 months. The patient with previous non union had BMP at the same time and radiologically healed in 10 months. Two patients had persistent bisphosphonate osteotomy lines but were asymptomatic. One patient had removal of a prominent distal locking screw and one had persistent Trendelenburg gait. Rigid intramedullary nailing is effective in stabilisation and deformity correction of long bones in adolescent patients with brittle bone disease. The technique has a low complication rate. We recommend the use of this technique in paediatric limb reconstruction in managing metabolic bone conditions.
We present a review of our Specialist Physiotherapy clinic for normal physiological variations of the lower limb (SPNV) clinics, demonstrating them to be clinically effective and cost effective. Children with normal variation of rotational profile and limb angulation present much anxiety to parents and primary care. Providing consultation: to eliminate significant pathology and reassure families, is an important service that a Paediatric Orthopaedic department provides. In our tertiary referral department we have a Specialist Physiotherapy led clinics into which primary care practitioners refer children with whom there are concerns about lower limb development variation. The (SPNV) Clinic was first set up by a Consultant and Senior Physiotherapist in 1999. The aim of the clinic was to reduce the waiting times for incoming referrals but ensuring they are seen in an appropriate environment by an experienced health care professional. Clinics are run by Senior Specialist Physiotherapists, alongside Consultant clinics who are available for advice and direction. This provides security for the physios, the Trust and the patient. Over 15 years there have been more than 4000 patient visits to this clinic. Over 80% were new patient visits. 70% of these visits were discharged in one or two reviews. 97.4% of new referrals were discharged without subsequent review by an orthopaedic surgeon. The most common conditions reviewed were Genu valgum (25%), Genu Varum (16%), intoeing (17%) and flexible flat feet (11%). The clinic has proven to be cost effective as well in drawing in up to £500,000 revenue into the trust in a single year. The department has been approached by other trusts to assist in the implementation of similar clinics. We present this review of the patients, as a template for supporting the work of Paediatric Orthopaedic Departments. This service has facilitated the streamlining of our Consultant Paediatric Orthopaedic clinics.
