Abstract. Objectives. Epiphysiodesis is a commonly used treatment for lower limb angular deformities. However, in recent years, distal tibial growth modulation using ‘eight plates’ or screws has emerged as an alternative treatment for paediatric foot and ankle disorders, such as CTEV. Our objective was to assess the efficacy of distal tibial modulation in correcting various paediatric foot and ankle disorders. Methods. This retrospective study analysed 205 cases of paediatric foot and ankle disorders treated between 2003 and 2022, including only cases where the eight plate or screw was fixed on the anterior surface of the distal tibia. Our aim was to measure post-operative changes in dorsiflexion, the distal tibial angle, and the tibiocalcaneal angle by examining clinical records and radiology reports. Results. We identified nine cases (nine feet) meeting the full inclusion criteria, comprising seven cases of CTEV, one case of arthrogryposis, and one case of cavovarus foot. The cohort consisted of five male and four female patients, with a mean age of 10 years and 9 months at the time of surgery. Seven cases involved the left tibia, and two cases involved the right tibia. The mean time between pre-operative X-ray to surgery was 168 days, and the mean turnaround time between surgery and post-operative X-ray was 588 days. A mean change in the distal tibial angle of 4.33 degrees was noted. However, changes in dorsiflexion were documented in only one case, which showed a change of 13 degrees. Notably, our average distal tibial angle was significantly lower than reported in the literature, at 4.33 degrees. Additionally, some studies in the literature used the Oxford Ankle Foot Questionnaire for Children to assess pre- and post-operative outcomes, but it is important to note that it is validated only for children aged 5 to 16. Furthermore, most cases reported an improved tibiocalcaneal angle except for an anomaly of 105 degrees. We assessed satisfactory patient outcomes using patient notes. Out of the 6 procured notes, one has been discharged. The rest are still under yearly or 6-monthly review and are at various stages, such as physiotherapy, removing the eight plate, or requiring further surgery. The most common presentations at review are plantaris deformity and pain. Conclusions. Our study suggests that distal tibial growth modulation can be an effective treatment option for selected paediatric foot and ankle disorders. However, due to the limited number of cases in our study, the lack of documentation of changes in dorsiflexion, and a lack of pre- and post-operative outcomes using a standardised method, further research is needed to investigate this procedure's long-term outcomes and potential complications.

Our study seeks to determine whether characteristics of radiographs taken post-reduction of a forearm fracture can indicate future risk of refracture or loss of reduction. We hypothesize that reducing forearm fractures too precisely may be counterproductive and provide less benefit than reductions left slightly offset prior to cast immobilization. We conducted a retrospective review of 1079 pediatric patients treated for forearm fractures between January 2014 and September 2021 in a 327 bed regional medical center. Percent fracture displacement, location, orientation, comminution, fracture line visibility and angle of angulation were determined by AP and lateral radiographs. Percent fracture displacement was derived by: (Displacement of Bone Shafts / Diameter) x 100% = %Fracture Displacement. Patients treated with closed reduction were reduced from a mean displacement of 29.26±36.18% at an angulation of 22.67±16.57 degrees to 7.88±9.07% displacement and 3.89±6.68 degrees angulation post-reduction. Patients developing complications including a loss of reduction or refracture were found to have post-operative radiographs with a lower percent displacement (0.50±1.12) than those not developing complications (8.65±9.21)(p=0.0580). Post-reduction angulation (p=1.000), average reduction in angulation (p=1.000) and average reduction in displacement percent(p=0.2102) were not significantly associated with development of complications. Percent displacement of radial shafts was seen to be the most important metric to monitor in post-operative radiographs for patients undergoing closed reduction of a forearm fracture. We theorize a slight displacement provides greater surface area for osteoblastic expansion and callus formation leading to a decreased risk of refracture or loss of reduction. While our sample size precludes our ability to measure the ideal amount of post-reduction displacement for optimal healing, our results demonstrate that some degree of shaft displacement is required for optimal healing conditions

Paediatric musculoskeletal (MSK) disorders often produce severe limb deformities, that may require surgical correction. This may be challenging, especially in case of multiplanar, multifocal and/or multilevel deformities. The increasing implementation of novel technologies, such as virtual surgical planning (VSP), computer aided surgical simulation (CASS) and 3D-printing is rapidly gaining traction for a range of surgical applications in paediatric orthopaedics, allowing for extreme personalization and accuracy of the correction, by also reducing operative times and complications. However, prompt availability and accessible costs of this technology remain a concern. Here, we report our experience using an in-hospital low-cost desk workstation for VSP and rapid prototyping in the field of paediatric orthopaedic surgery. From April 2018 to September 2022 20 children presenting with congenital or post-traumatic deformities of the limbs requiring corrective osteotomies were included in the study. A conversion procedure was applied to transform the CT scan into a 3D model. The surgery was planned using the 3D generated model. The simulation consisted of a virtual process of correction of the alignment, rotation, lengthening of the bones and choosing the level, shape and direction of the osteotomies. We also simulated and calculated the size and position of hardware and customized massive allografts that were shaped in clean room at the hospital bone bank. Sterilizable 3D models and PSI were printed in high-temperature poly-lactic acid (HTPLA), using a low-cost 3D-printer. Twenty-three operations in twenty patients were performed by using VSP and CASS. The sites of correction were: leg (9 cases) hip (5 cases) elbow/forearm (5 cases) foot (5 cases) The 3D printed sterilizable models were used in 21 cases while HTPLA-PSI were used in five cases. customized massive bone allografts were implanted in 4 cases. No complications related to the use of 3D printed models or cutting guides within the surgical field were observed. Post-operative good or excellent radiographic correction was achieved in 21 cases. In conclusion, the application of VSP, CASS and 3D-printing technology can improve the surgical correction of complex limb deformities in children, helping the surgeon to identify the correct landmarks for the osteotomy, to achieve the desired degree of correction, accurately modelling and positioning hardware and bone grafts when required. The implementation of in-hospital low-cost desk workstations for VSP, CASS and 3D-Printing is an effective and cost-advantageous solution for facilitating the use of these technologies in daily clinical and surgical practice

To investigate changes in quadriceps and hamstrings muscle groups during sustained isokinetic knee flexion and extension. 125 paediatric participants (45 males and 80 females, mean age 14.2 years) were divided into two groups: participants with a confirmed ACL tear (ACLi, n = 64), and puberty- and activity-level matched control participants with no prior history of knee injuries (CON, n = 61). Participants completed a series of 44 repetitions of isokinetic knee flexion and extension at 90 deg/ sec using a Biodex dynamometer (Biodex Medical Systems Inc, Shirley, New York). Surface EMG sensors (Delsys Incorporated, Natick, MA) simultaneously recorded the quadriceps and hamstring activations. Muscle function was assessed as the change in quadriceps activation and extension torque were calculated using the percent difference between the mean of the first five trials, and the mean of the last five trials. ACLi participants had significantly higher percent change in quadriceps activation for both healthy and injured legs, in comparison to CON dominant leg. As such, the healthy leg of the ACLi participants is activating significantly more than their health matched controls, while also demonstrating reduced muscular endurance (less torque in later repetitions). Therefore, we conclude that the non-injured limb of the ACLi participant is not performing as a healthy limb. Since return to activity clearance following ACLi implies return to sport against age- and activity matched opponents, clearing young athletes based on the non-injured contralateral limb may put them at greater risk of reinjury

‘Safety’ is at the centre of surgical practice with the aim of minimising the risks of complications and adverse events. Much evidence, based on either retrospective case series or prospective cohorts, concerns the frequency of adverse events. There may be a temptation to describe a procedure as ‘safe’ if no – or few – serious adverse events (the numerator) have occurred out of a number of procedures performed (the denominator). In 1983, Hanley and Lippman-Hand described a simple algorithm to calculate the 95% upper Confidence Interval for data sets in which the numerator is zero (ie series in which there no adverse events). Paediatric orthopaedics suffers from small datasets which may make its researchers especially prone to the erroneous attribution of procedures being ‘safe’. The aim of the current study was to formally assess the evidence on which paediatric orthopaedic surgical procedures are described as ‘safe’. In particular, the objective was to ascertain the proportion of studies describing a procedure as ‘safe’ which achieved a 95% upper limit Confidence Interval of risk of 5% for major adverse events. We examined all papers published by the Journal of Paediatric Orthopaedics in the previous 5 years searching for the single term ‘safe’. 84 papers were returned and 71 were considered appropriate for analysis. Of these 60 papers positively identified their intervention as ‘safe’. These papers were read in full and the number of interventions was recorded along with the rate of complication. 66 data sets were created and the 95% upper confidence interval was calculated for complication rates. Only 16 out of 66 data sets could safely predict a major complication rate of under 5%. Our work would tend to suggest that a failure to apply proper statistical tools is leading to procedures being erroneously classified as safe in the published literature

Purpose. Flat feet are an important cause of foot problems in children. The flexible flat foot is the most common form and is normally physiological and asymptomatic. Further assessment is necessary when a symptomatic flat foot persists. Surgical interventions are indicated when conservative therapies have failed. The Kalix arthroereisis is a surgical option and is placed in the subtalar joint of the foot, thereby preventing hyperpronation, and stabilizes the foot against excessive movements. The purpose of this study was to evaluate the functional and radiological outcomes of pediatric patients who had undergone a Kalix implantation for the treatment of a symptomatic flexible flat foot. Methods. Patient files of our institution were searched for patients who underwent a Kalix implantation between 2009 and 2014. Sixteen patients (26 feet) with symptomatic flexible flat feet were clinically and radiographically evaluated in this retrospective study. The calcaneal pitch and Meary”s angle were measured on the pre-, and postoperative follow-up radiographs and patient satisfaction survey was performed at follow-up to gain insight into functional outcome and satisfaction after the intervention. Results. Surgery was performed on an average age at 12.5 (range:10–15) years with a mean time from surgery to follow-up of 45.1±3.16 (range:18–78) months. There was a statistically significant increase in calcaneal pitch of 2.9° (11.7°to14.6°) and decrease in Meary”s angle of 15.8° (23.2° to7.85°) after surgery. The postoperative angles were maintained during follow-up, for both the calcaneal pitch (13.89°) and Meary”s angle (8.67°) in patients with the Kalix in situ (n=9/26) and in patients with the Kalix removed (15.4° and 7.8° respectively, n=17/26). The patient satisfaction survey shows that the majority of patients were satisfied regarding the state (81%) and appearance (75%) of their feet at follow-up. The majority never complained about their feet (81%) and heavy exercise was the major cause of complaints (23%). Limitations during walking were usually not the case (81%), though some patient experienced limitations during running (57%). Most reported preoperative complaints were pain, walking problems or a combination of both. The majority of these are relieved after surgery and patients were still asymptomatic at follow up. Conclusion. Kalix implantation improves the calcaneal pitch and Meary”s angle, thereby restoring foot anatomy towards a normal anatomy. These improvements were observed directly postoperatively and remained at follow-up. In addition, relieve of symptoms was observed postoperatively and the majority of patients were even satisfied at follow-up. We therefore suggest that Kalix arthroereisis is an appropriate treatment option for pediatric patients with symptomatic flexible flat feet. Significance. This was the first study evaluating functional and radiological outcomes of the Kalix arthroereisis in patients with symptomatic flexible flat feet

Supracondylar fractures of the humerus (SCFH) are the most common type of paediatric elbow fractures. Due to beliefs that non-operatively managed SCFH may displace further from the original position, they are monitored with repeated radiographs and a large number are unnecessarily surgically pinned. Very limited evidence currently exists to support these beliefs. This study aimed to determine the incidence of late “significant” displacement (requiring surgical management) of non-operatively managed paediatric SCFH, and whether they necessitate close radiographic follow-up. Patients aged ≤16, with a SCFH, were included in this retrospective cohort study. All were initially managed non-operatively with at least one follow-up radiograph within six weeks of injury. Data from four consecutive years (2013–2016) was collected using the hospital's radiology database. Two observers independently analysed patient radiographs and classified fractures by the Gartland and AO systems. The incidence of late displacement was determined using follow-up radiographs and clinic notes. Of the 164 patients included in the study, one patient (Gartland Type II, AO Type III) suffered late displacement at two weeks, requiring surgical fixation. One further patient (AO Type II) had a persistent cubitus varus deformity (Baumann's angle 90°), with no long-term functional deficit. Incidence of late displacement was 0.6% (n=1). Our findings suggest that stable Gartland Type I/AO Type I and II fractures do not require repeated radiographic follow-up. However, some Gartland Type II/AO Type III fractures require monitoring. This could considerably reduce the financial costs for the healthcare system, and inconvenience to families, associated with repeated follow-ups

Femoral shaft fractures are potentially devastating injuries. Despite this, clinical studies of the biomechanics of this injury are lacking. We aimed to clinically evaluate bone behaviour under high and low energy trauma in paediatric, adult and older patients. Single-centre retrospective study identifying all diaphyseal femoral fractures between Feb 2015-Feb 2017. Peri-prosthetic and pathological fractures were excluded. Patients were subdivided into groups 1 (paediatric, <16yo), 2 (adult, 17–55yo) and 3 (older, >55yo) to reflect immature, peak bone age and osteoporotic bone respectively. Chi-Squared analysis assessed significance of bone age to degree of comminution and fracture pattern. A p-value <0.05 was significant. A total 4130 radiographs were analysed with 206 femoral shaft fractures identified. Forty-three patients were excluded with 163 remaining. Group 1, 2 and 3 included 38, 37 and 88 patients respectively. Mean age 50.8 (SD 32.8) with male-to-female ratio of 1:1.2. Groups 1 and 3 included majority simple fractures (35/38 and 62/88 respectively). Group 2 included more comminuted injuries (33/37). Bone age to degree of comminution proved significant (p<0.05) with a bimodal distribution of simple fractures noted in groups 1 and 3. Energy to fracture was significant in group 2, where a high energy injury was associated with comminution (p<0.05). This study is the first to demonstrate an association between fracture comminution and age. Simple femoral shaft fractures showed a bimodal age distribution in paediatric and older patients regardless of mechanism energy. High energy mechanism trauma was directly related to fracture comminution at peak bone age

Forearm fractures are a common paediatric injury. This study was aimed to describe the epidemiological of paediatric forearm fractures in the urban population of Glasgow. We reviewed of all the forearm fracture treated by the orthopaedic service in Yorkhill Children's Hospital in 2008. Datum gathered from case notes and radiographs using the prospective orthopaedic database to identify patients with forearm fractures. The age, sex, side and type of fracture, the timing and mechanism of the injury and treatment were documented for the 436 fractures. Census data were used to derive absolute age-specific incidences. Distinction was made between torus and other types of fractures. Torus fractures require no specific orthopaedic treatment and were segregated out. For the remaining 314 fractures, the age and sex distribution, seasonal variation of fractures and treatments for each type of fracture were examined. The incidence of forearm fractures in our population is 411 fractures per 100,000 population per year. An increased number of fractures occurred during the months of May and August. A fall from less than one metre was the commonest mechanism of injury, sporting injuries were the second commonest with football the most common sport associated. This study identifies some features which are in good agreement with studies from elsewhere in Britain, such as incidence and seasonality. However, there are also interesting differences – such as the Glasgow peak incidence for forearm fractures being at age 8, with a marked decline by 12 years. Furthermore, our findings have been extended to consideration of type of intervention, and likelihood of successful treatment

The process of gaining informed consent can be a complex and much debated pursuit, especially within a paediatric setting. The role of the trainee surgeon and its explanation to children and their families prior to an operation has not been explored from the resident surgeons' point of view. Ten face-to-face interviews were conducted with orthopaedic surgery trainees at a tertiary level paediatric hospital in Toronto, Canada. These were transcribed and subsequently thematically coded by 3 reviewers. Three main themes were identified from the interviews. 1) Surgical trainees feel their level of participation and autonomy gradually increases dependent on their observed skills and level of training. 2) Trainees feel the consent process is adequate but acknowledge it is often purposely vague with regards to their intra-operative involvement as this is often unpredictable and it avoids patient/family anxiety. 3) Trainees believe families are aware of their participation however most likely underestimate their role during operations. Trainees in surgical specialties believe their level of autonomy is variable dependent on a number of factors and that this impacts on the ability to be more specific when gaining informed consent. This must be balanced with a family's right to an appropriate understanding of their child's operation and who is performing it. It may be that further patient education regarding trainees and their role in operations would help develop a more thorough and patient centred informed consent process

Introduction. Two randomised trials concluded cast type (above or below elbow) makes no significant difference in the re-displacement rate of paediatric forearm fractures involving the distal third of the radius. This has not, however, led to the universal use of below elbow casts. In particular we noted one trial reported significant re-displacement in 40% or more of cases, which was much higher than we would expect. To review the radiological outcomes and need for re-manipulation of paediatric distal forearm fractures treated with closed manipulation under anaesthesia in our institution, in part for subsequent comparison with published results. All forearm fractures treated at a specialist children's hospital in one year were reviewed retrospectively. Based on the methodology of one trial, we included all fractures involving the distal third of the radius, with or without an ulna fracture, which underwent closed manipulation. Outcomes were radiological alignment using existing radiographs and need for re-manipulation. Cast type was at the discretion of the treating surgeon. The radiological criteria for re-displacement were based on published methodology. 79 children underwent manipulation, 71 receiving above elbow casts and 8 below elbow casts. Radiologically 21% of injuries treated in an above elbow cast re-displaced (15/71) compared to 38% of those in below elbow plasters (3/8). In 2 cases the re-displacement was treated with re-manipulation. The preference in our institution was clearly for above elbow casts in this injury pattern. The small number of below elbow casts in our series limits any comparisons. Our rate of re-displacement using above elbow casts was half that of one of the published studies, so the existing literature is not consistent with our experience

Pelvic fractures in children are uncommon. Despite their potentially serious nature, there is little information in the literature regarding their epidemiology. We performed a retrospective review of case notes and radiographs, if available, of all patients admitted with bony pelvic injuries to our unit over a 28 year period (1980-2008). Sixty-four children with pelvic fractures were identified (median age 8 years, 75% male). 58% were pedestrians involved in road traffic accidents (RTA), 19% were caused by a fall from a height and 8% were crush injuries. There was seasonal variability, with a 50% increase in pelvic injuries in Autumn and 33% decrease in Winter - compared to Spring/Summer months (in contrast to the peak in overall fracture incidence in the Summer). Median length of stay was 8 days (range 1-180), 11% requiring direct admission to ITU and 5% to HDU. There is a high incidence of associated major injuries - for Stable fractures 52%, Partially stable fractures 60% and Unstable fractures 100%. Five required surgery to the bony pelvis, and 6 for-non pelvic orthopaedic injury. 3 required operative intervention from other specialities, 1 urological repair, 1 laparotomy and 1 lobectomy. Pelvic fractures in children are potentially serious injuries with a high proportion of major associated injuries. Multiple injuries were sustained in 55% of pedestrian/RTA accidents, 100% of crush injuries and 58% of falls from a height. In this series, 52% of “Stable” pelvic injuries were associated with other major injuries. All paediatric pelvic injuries, even stable pubic rami fractures should be approached with caution, full ATLS assessment and close monitoring

Neurological examination in children presenting with upper limb fractures is often poorly performed. In the peripatetic emergency department environment this may be confounded by patient distress or reduced comprehension. We aimed to assess the quality of documented neurological examination in children presenting with upper limb fractures and whether this could be improved following introduction of a simple guideline for paediatric neurological assessment. We reviewed the clinical notes of all children presenting to the emergency department with upper limb fractures over a three month period. Documentation of initial neurological assessment and clinical suspicion of any nerve injury were noted. Subsequently, we introduced a guideline for paediatric upper limb neurological examination (‘Rock, Paper, Scissors, OK’) to our hospital and performed a further 3 month review to detect resulting changes in practice. In the initial study period, 121 children presented with upper limb fractures. 10 (8%) had a nerve injury. Neurological examination was documented in 107 (88%) of patients. However, information on nerves examined was only recorded in 5 (5%) with the majority (85%) documented as ‘neurovascuarly intact’. None of the nerve injuries were detected on initial assessment. Following guideline introduction, 97 patients presented with upper limb fractures of which 8 children (8%) had a nerve injury. Documentation of neurological examination increased to 98% for patients presenting directly to our own hospital (Fisher's Exact Test, p=0.02) with details of nerves examined increasing to 69%. Within this cohort all nerve injuries with objective motor or sensory deficits were detected on initial examination. The recent British Orthopaedic Association Standards for Trauma (BOAST) guideline on peripheral nerve injuries emphasises the importance of clearly recorded neurological assessment in trauma patients. Our study shows that introduction of a simple guideline for neurological examination in children with upper limb fractures can significantly improve the quality of documented neurological assessment and detection of nerve injuries

Neurological examination is essential in patients with upper limb injuries and should be clearly documented. We aimed to assess the quality and documentation of neurological examination performed for children presenting with upper limb fractures to the emergency department. Clinical notes of all children admitted with upper limb fractures over a three month period were reviewed. Documentation of initial neurological assessment was analysed and clinical suspicion of any nerve injury noted. In parallel, we conducted an anonymous survey of emergency doctors evaluating their upper limb neurological examination in children. The casenotes of 121 children with upper limb fractures were reviewed. 10 children (8%) had a nerve injury (median = 4, ulnar = 2, radial = 2, anterior interosseous = 2). Neurological examination was documented in 107 (88%) of patients. However, none of the nerve injuries were detected on initial examination. In patients with nerve injuries, 5 (50%) were documented as being ‘neurovascularly intact’, 2 (20%) as ‘CSM normal’, 1 (10%) as ‘moving fingers’ and 2 (20%) had no documented neurological examination. 30 emergency doctors completed the questionnaires (5 consultants, 9 registrars, 16 foundation doctors). All doctors stated that they routinely performed an upper limb neurological examination and assessed median, ulnar and radial nerves. However, 30% of doctors described incomplete examination of median nerve function, 30% inadequate ulnar nerve assessment and 50% incomplete radial nerve examination. In addition, 75% of doctors failed to identify the need for assessment of anterior interosseous nerve function. While emergency doctors recognise the importance of neurological assessment in children with upper limb injuries, it is often performed inadequately. This in part may be due to difficulties performing neurological examination in paediatric patients. As a result of this study, we have introduced local guidelines to assist neurological assessment in children

To investigate differences in the drop vertical jump height in female adolescents with an ACL injury and healthy controls and the contribution of each limb in this task. Forty female adolescents with an ACL injury (ACLi, 15.2 ± 1.4 yrs, 164.6 ± 6.0 cm, 63.1 ± 10.0 kg) and thirty-nine uninjured (CON, 13.2 ± 1.7 yrs, 161.7 ± 8.0 cm, 50.6 ± 11.0 kg) were included in this study. A 10-camera infrared motion analysis system (Vicon, Nexus, Oxford, UK) tracked pelvis, thigh, shank, and foot kinematics at 200Hz, while the participants performed 3 trials of double-legged drop vertical jumps (DVJ) on two force plates (Bertec Corp., Columbus, USA) sampled at 2000Hz.The maximum jump height normalised by dominant leg length was compared between groups using independent samples t-test. The maximum vertical ground reaction force (GRFz) and sagittal ankle, knee and hip velocities before take-off were compared between limbs in both groups, using paired samples t-test. The normalised jump height was 11% lower in the ACLi than in the CON (MD=0.04 cm, p=0.020). In the ACLi, the maximum GRFz (MD=46.17N) and the maximum velocities of ankle plantar flexion (MD=79.83°/s), knee extension (MD=85.80°/s), and hip extension (MD=36.08°/s) were greater in the non-injured limb, compared to the injured limb. No differences between limbs were found in the CON.

ACL injured female adolescents jump lower than the healthy controls and have greater contribution of their non-injured limb, compared to their injured limb, in the DVJ task. Clinicians should investigate differences in the contribution between limbs during double-legged drop vertical jump when assessing patients with an ACL injury, as this could help identify asymmetries, and potentially improve treatment, criteria used to clear athletes to sport, and re-injury prevention.

Background

The pattern of appearance of secondary ossification centers in the elbow has been based on historical studies and is popularly referred to with the mnemonic CRITOL. However the six secondary ossification centers can be variable in their presentation and pose a challenge in assessment of children with elbow injuries. Furthermore limited studies available in the current literature have reported an aberration to the sequence of appearance especially with the ossification centers of trochlea and olecranon.

Aims

The aim of the study was to evaluate the relative sequence of appearance of secondary ossification centers for the trochlea and olecranon.

We noted, in the immature ankle, a discrepancy between the alignment of the distal tibial physis, the distal tibial articular surface and the talar dome in the coronal plane. This led to variability in the orientation of wires and half pins used for limb reconstruction depending on which landmark was used. We aimed to investigate the variability in normal ankle joints to determine which is the most reliable landmark to use for correct wire or pin insertion.

Radiographs of the ankle of 98 children were analysed. A variety of angular measurements were made with respect to the axis of the tibia and classified according to methods described by Shapiro & Mulhotra.

We investigated the inter- and intra-observer variation in these measurements and classifications. Using the Bland-Altman method we found that the talar plafond angle (TPA) showed less variation than the lateral distal tibial angle (LDTA) with narrower limits of agreement and coefficients of repeatability. This was the same across the age and gender groups studied.

The Shapiro classification of distal tibial epiphyseal shape did not appear to correlate with age or gender, but showed more inter- and intra-rater variation using weighted Kappa analysis.

This study suggests that when measuring the orientation of the ankle joint from plain radiographs that the TPA is a more reliable measurement than the LDTA and this should be taken into consideration during decision making and pre-operative planning of lower limb deformity correction.

During the cold snap in the West of Scotland 20 December 2009 to 10 January 2010 there was a cluster of uncommon lower limb injuries in children from sledging accidents. These cases are presented as a series.

This retrospective descriptive study details acute orthopaedic admissions for the period of the cold snap. The case-notes for all admissions were reviewed for diagnosis, mechanism of injury.

Five (ex 20 ie 1/4) trauma admissions involved sledging: (1) combined avulsion of anterior and posterior cruciate ligaments left knee (2) Lisfranc injury, (3) distal femoral fracture, (4) distal tibial plafond fracture, (5) pelvis, patella also forearm and facial fractures. These cases are analysed in more detail

Sledging injuries comprise a substantial portion of workload and morbidity. In children, there is a propensity for lower limb and higher energy trauma. Tertiary referrals and non-standard trauma equipment may be required.

We present a novel use for an adult proximal humeral locking plate. In our case an 18-year-old female with cerebral palsy sustained a peri-prosthetic fracture of a blade plate previously inserted for a femoral osteotomy. Treatment was revision using a long proximal humeral locking plate. She had a successful outcome.

We present the history and operative management.

The female had a history of quadriplegic cerebral palsy, asthma, diabetes mellitus and congenital heart disease. She had a gastrostomy tube for enteral feeding. She was on nutritional supplements, baclofen, Omeprazole and movicol. She is looked after by her parents and requires a wheelchair for mobility. She is unable to communicate. Surgical History: Right adductor tenotomy, aged 11. Femoral Derotation Osteotomy & Dega Acetabular Osteotomy, aged 13. Right distal hamstring and knee capsule release, aged 14. Admitted to A&E (aged 18); unwitnessed fall. Painful, swollen, deformed thigh with crepitus. Xrays demonstrated peri- prosthetic fracture below blade plate.

No specific equipment available to revise. Decision made to use PHILOS (Synthes, UK). GA, antibiotics, supine on table. Lateral approach. Plate removed after excising overgrown bone. Reduced and held. 10hole PHILOS applied. Near anatomical reduction. Secure fixation with locking screws proximally away from blade plate defect. Blood loss 800ml. 5 days in hospital. Sequential fracture clinic review. Wound healed well. Fracture healed on Xray at 11 months and discharged.

To our knowledge this is the first reported use of a PHILOS plate for this specific fracture. The complexity of this case and underlying neurological disorder deemed long blade plate revision unsuitable. Fracture rates after femoral derotation osteotomies rare. 5/157 and 1/58 in the two largest studies to date. Conservative measures were the main recommendation. We have demonstrated a straightforward method for revision fixation with an excellent outcome. It would be recommended as an alternative to other surgeons in this position.
