Background: Torus (buckle) fractures of the wrist are the most common fractures in children, involving the distal radius and/or ulna. It is unclear if children require rigid immobilisation and follow-up, or would equally recover by being discharged without any immobilisation or a bandage. Given the large number of these injuries, identifying the optimal treatment strategy could have important effects on the child, school absences and NHS costs. Objectives: To establish whether treating children with a distal radius torus fracture with the offer of a soft bandage and immediate discharge (“offer of bandage”), provides the same recovery, in terms of pain, function, complications, acceptability, school absence and resource use, as treatment with rigid immobilisation and follow-up as per usual practice (“rigid immobilisation”). Design: A pragmatic, multicentre, randomised controlled equivalence trial. Setting: 23 UK Emergency Departments. Participants: 965 children (4-15 years) with a distal radius torus fracture were randomised from January 2019 to July 2020 using a secure, centralised, online encrypted randomisation service. Exclusion criteria included presentation >36 hours after injury, multiple injuries and inability to complete follow-up. Interventions: Offer of bandage (n= 489) of whom the bandage was applied in 458, versus rigid immobilisation (n= 476). Participants and clinicians were not blinded to the treatment allocation. Main outcome measures: Pain at 3-days post-randomisation measured using the WongBaker FACES Pain Rating Scale. Secondary outcomes were the PROMIS Upper Extremity score for children, health related quality of life (QoL), complications, school absence, analgesia use and resource use collected up to 6 weeks post-randomisation. Results: 94% of participants provided primary outcome data. Pain was equivalent at the 3 day primary outcome for both groups. With reference to the pre-specified equivalence margin of 1.0, the adjusted difference in the intention-to-treat population was -0.10; 95% CI -0.37 to 0.17 and the per-protocol population was -0.06; 95% CI -0.34 to 0.21. There was equivalence in pain for both age subgroups (4-7 and 8–15 years). There was no difference in the rate of complications, with five (1.0%) in the offer of bandage group and three (0.6%) in the rigid immobilisation group. There were no differences between treatment groups in functional recovery, QoL or school absence at any point during follow-up. Analgesia use was marginally higher at Day 1 in the offer of bandage group (83% vs 78% participants), though was no different at other times. The offer of bandage significantly reduced the cost of treatment, and had a high probability of cost-effectiveness. Limitations: Families had a strong pre-existing preference for rigid immobilisation. Given this, and the inability to blind families to the treatment allocation, observer bias was a concern. However, there was clear evidence of equivalence. Conclusions: The study findings support the offer of bandage in children with a distal radius torus fracture.

Hip displacement in children with cerebral palsy (CP) is a complex problem and requires a multidisciplinary team approach. It is the most common orthopaedic problem in the non-ambulatory group of children and causes significant pain, which can be prevented or treated with appropriate management. Hip subluxation occurs due to asymmetrical muscle imbalance in the context of abnormal proximal femoral morphology. Work from CP registries has shown strong correlation between Gross Motor Function Classification System (GMFCS) level and rate of hip displacement. This has led to the development of preventative surveillance programmes. This review focuses particularly on non-ambulatory patients (GMFCS IV/V) and the options open to the paediatric orthopaedic surgeon in managing associated hip displacement. Surgical strategies can be broadly grouped into preventative, reconstructive and salvage options.

Aims To determine the impact of COVID-19 on orthopaediatric admissions and fracture clinics within a regional integrated care system (ICS). Methods A retrospective review was performed for all paediatric orthopaedic patients admitted across the region during the recent lockdown period (24 March 2020 to 10 May 2020) and the same period in 2019. Age, sex, mechanism, anatomical region, and treatment modality were compared, as were fracture clinic attendances within the receiving regional major trauma centre (MTC) between the two periods. Results Paediatric trauma admissions across the region fell by 33% (197 vs 132) with a proportional increase to 59% (n = 78) of admissions to the MTC during lockdown compared with 28.4% in 2019 (N = 56). There was a reduction in manipulation under anaesthetic (p = 0.015) and the use of Kirschner wires (K-wires) (p = 0.040) between the two time periods. The median time to surgery remained one day in both (2019 IQR 0 to 2; 2020 IQR 1 to 1). Supracondylar fractures were the most common reason for fracture clinic attendance (17.3%, n = 19) with a proportional increase of 108.4% vs 2019 (2019 n = 20; 2020 n = 19) (p = 0.007). While upper limb injuries and falls from play apparatus, equipment, or height remained the most common indications for admission, there was a reduction in sports injuries (p < 0.001) but an increase in lacerations (p = 0.031). Fracture clinic management changed with 67% (n = 40) of follow-up appointments via telephone and 69% (n = 65) of patients requiring cast immobilization treated with a 3M Soft Cast, enabling self-removal. The safeguarding team saw a 22% reduction in referrals (2019: n = 41, 2020: n = 32). Conclusion During this viral pandemic, the number of trauma cases decreased with a change in the mechanism of injury, median age of presentation, and an increase in referrals to the regional MTC. Adaptions in standard practice led to fewer MUA, and K-wire procedures being performed, more supracondylar fractures managed through clinic and an increase in the use of removable cast.

Aims To our knowledge, there is currently no information available about the rate of venous thromboembolism (VTE) or recommendations regarding chemoprophylaxis for patients whose lower limb is immobilized in a plaster cast. We report a retrospective case series assessing the rate of symptomatic VTE in patients treated with a lower limb cast. Given the complex, heterogeneous nature of this group of patients, with many risk factors for VTE, we hypothesized that the rate of VTE would be higher than in the general population. Patients and Methods Patients treated with a lower limb cast between 2006 and 2018 were identified using plaster room records. Their electronic records and radiological reports were reviewed for details about their cast, past medical history, and any VTE recorded in our hospital within a year of casting. Results There were 136 episodes of casting in 100 patients. The mean age was 55 years (22 to 91). The mean time in a cast was 45 days (five days to eight months). A total of 76 patients had neuropathy secondary to diabetes. No patient received chemical thromboprophylaxis while in a cast. One VTE (0.7% of casting episodes) was documented. This was confirmed by Doppler scan nine days after removing the cast. Conclusion The frequency of VTE was higher than that of the general population (0.05%); this is most likely attributable to our patients’ apparent increase in VTE risk as suggested by The National Institute for Health and Care Excellence (NICE). These findings suggest that thromboprophylaxis is not routinely indicated in patients who undergo immobilization of the lower limb in a cast, although the risks of VTE should be assessed. While the cast itself does not pose an increased risk, other pathologies, such as active cancer, mean that each individual case needs to be considered on their merit.

Aims This study sought to estimate the clinical outcomes and describe the nationwide variation in practice, as part of the feasibility workup for a National Institute for Health and Care Excellence (NICE) recommended randomized clinical trial to determine the optimal treatment of torus fractures of the distal radius in children. Methods Prospective data collection on torus fractures presenting to our emergency department. Patient consent and study information, including a copy of the Wong-Baker Faces pain score, was issued at the first patient contact. An automated text message service recorded pain scores at days 0, 3, 7, 21, and 42 postinjury. A cross-sectional survey of current accident and emergency practice in the UK was also undertaken to gauge current practice following the publication of NICE guidance. Results In all, 30 patients with a mean age of 8.9 years were enrolled over a six-week period. Of the 150 potential data points, data was captured in 146, making the data 97.3% complete. Pain scores were recorded at day 0 (mean 6.5 (95% confidence interval (CI) 5.7 to 7.3)), day 3 (4.4 (95% CI 3.5 to 5.2)), day 7 (3.0 (95% CI 2.3 to 3.6)), day 21 (1.2 (95% CI 0.7 to 1.7)) and day 42 (0.4 (95% CI 0.1 to 0.7)). Of the 100 units who participated in the nationwide survey, 38% were unaware of any local or national protocols regarding torus fractures, 41% treated torus fractures with cast immobilization, and over 60% of patients had follow-up arranged, both contradictory to national guidelines. Conclusion We have demonstrated the severity, recovery trajectory, and variation in pain scores among children with torus fractures. We demonstrate excellent follow-up of patient outcomes using text messages. Despite national guidelines, there is significant variation in practice. This data directly informed the development of an ongoing nationwide randomized clinical trial – the FORearm Fracture Recovery in Children Evaluation (FORCE) study.

Aims Torus fractures are the most common childhood fracture, accounting for 500,000 UK emergency attendances per year. UK treatment varies widely due to lack of scientific evidence. This is the protocol for a randomized controlled equivalence trial of ‘the offer of a soft bandage and immediate discharge’ versus ‘rigid immobilization and follow-up as per the protocol of the treating centre’ in the treatment of torus fractures . Methods Children aged four to 15-years-old inclusive who have sustained a torus/buckle fracture of the distal radius with/without an injury to the ulna are eligible to take part. Baseline pain as measured by the Wong Baker FACES pain scale, function using the Patient-Reported Outcomes Measurement Information System (PROMIS) upper limb, and quality of life (QoL) assessed with the EuroQol EQ-5D-Y will be collected. Each patient will be randomly allocated (1:1, stratified by centre and age group (four to seven years and ≥ eight years) to either a regimen of the offer of a soft bandage and immediate discharge or rigid immobilization and follow-up as per the protocol of the treating centre. Results At day one, three, and seven, data on pain, function, QoL, immobilization, and analgesia will be collected. Three and six weeks after injury, the main outcomes plus data on complications, resource use, and school absence will be collected. The primary outcome is the Wong-Baker FACES pain scale at three days post-randomization. All data will be obtained through electronic questionnaires completed by the participants and/or parents/guardian. Cite this article: Bone Joint Open 2020;1-6:214–221.

Paediatric forearm fractures are a common presentation to orthopaedic surgeons. They include a number of different injuries including diaphyseal fractures, distal radius fractures and Galeazzi equivalent injuries. Apart from angulation, there is often a rotational component to the injury that must be assessed and accounted for to allow adequate reduction. The majority can be treated via conservative methods however K-wire fixation, plating and more recently elastic nails have all been utilised to good effect. K-wires can be used in a trans-physeal fashion or via an intrafocal technique. Outcomes between plate and nail fixation appear similar but nails offer better cosmesis and easier hardware removal. There has been a recent trend towards non-operative treatment of grade 1 open injuries of the forearm but this is yet to have the backing of level I evidence.

Category: Diabetes Introduction/Purpose: Venous Thrombo-Embolism (VTE) is a recognized complication of lower limb immobilization. In the neuropathic patient total contact casting (TCC) is used in the management of acute charcot neuroathropathy and/or to off-load neuropathic ulcers. To our knowledge, there is currently no literature stating the prevalence of VTE in patients, despite the possibility of prolonged lower limb immobilization. There are also no recommendations regarding VTE prophylaxis in the setting of TCCs. We report a retrospective case series assessing the frequency of symptomatic VTE in the patients treated with TCCs. Given that diabetic foot disease manifests as one of many co-morbidities in this medically complex group of patients we hypothesize that the rate of occurrence of VTE should be higher than that of the general population. Methods: Patients undergoing TCC between 2006 and 2018 were identified using plaster room records. These patients subsequently had electronic clinical letters and radiological reports assessed for details around the TCC episode, past medical history and any VTE events. Results: There were 143 TCC episodes in 105 patients. Average age at cast application was 55 years. The mean time in a cast was 45 days (range from 5 days to 8 months). 3 out of 4 patients had neuropathy as a consequence of diabetes. One TCC related VTE (0.7% of casting episodes) was documented. This was a proximal DVT confirmed on USS 9 days following cast removal. Only 3 patients received VTE prophylaxis while in TCC. Conclusion: Despite these complex patients having a multitude of co-morbidities the frequency of VTE in the TCC setting remains similar to that of the general population. This may be due to the fact that TCCs permit weight bearing or that Charcot arthropathy leads to a high outflow state, potentially turning Virchow’s triad in the patient’s favour. This case series suggests that, while all patients should be individually VTE risk assessed as for any lower limb immobilization, chemical thromboprophylaxis is not routinely indicated in the context of TCCs.

Category: Diabetes Introduction/Purpose: Diabetic foot infection (DFI) is a devastating condition which poses risk to both life and limb. Treatment principles revolve around surgical debridement, dead space management, delivery of both local and systemic antibiotics and soft tissue cover. Dead space management and local antibiotic delivery can be achieved simultaneously by using an antibiotic loaded bone substitute. We report our retrospective case series of patients treated with surgical management involving local antibiotic delivery via calcium sulphate bone substitute (Stimulan™; Biocomposites, Keele, UK). Methods: All patients between January 2015 and June 2018 with DFI and proven bony involvement presenting to our university teaching hospital were treated via our extensive MDT approach. A total of 102 patients were included. Surgical debridement was performed along with simultaneous insertion of 10 ml calcium sulphate with 1 g vancomycin and 240 mg gentamycin. Outcome was classified as resolved, requiring prolonged treatment from other medical (endocrinologist) or surgical (plastic surgery, limb reconstruction) services or salvage surgery in the form of proximal amputation. Results: 45.1% of patients had a partial amputation at the index surgery. 52% had bony debridement and just 2.9% had soft tissue debridement in conjunction with calcium sulphate insertion. The surgical wound was primarily closed in 56.8% of patients. 7 patients had delayed wound closure and 36.2% of patients healed via secondary intention. 74 patients (72.5%) had resolution of their DFI with bony involvement following surgical intervention. 21 (20.6%) patients needed further treatment from allied specialties. 7 (6.9%) patients required salvage surgery in the form of a below knee amputation. There was no correlation between either closure type (2 p-value 0.75) or index surgery type and outcome (2 p-value 0.64). Conclusion: DFI is a difficult clinical scenario to treat effectively. An MDT approach is undoubtedly key to a good outcome. We believe that the use of calcium sulphate can be a useful adjunct at the time of surgical debridement to aid in both dead space management and allow local antibiotic delivery.

Surgical access to the subtalar joint is required in a plethora of pathologic conditions of the hindfoot. The conventional lateral approach can give excellent access to subtalar joint; however, in hindfoot valgus deformities, there can be unacceptable risks of wound problems and incomplete deformity corrections. The medial approach offers good access to the subtalar joint with an increasing evidence base for its use, especially with double fusions in pes planus deformities. The authors review the current evidence in the use of the medial approach for the subtalar joint.

We present a classification system that progresses in severity, indicates the pathomechanics that cause the fracture and therefore guides the surgeon to what fixation will be necessary by which approach.The primary posterior malleolar fracture fragments were characterized into 3 groups. A type 1 fracture was described as a small extra-articular posterior malleolar primary fragment. Type 2 fractures consisted of a primary fragment of the posterolateral triangle of the tibia (Volkmann area). A type 3 primary fragment was characterized by a coronal plane fracture line involving the whole posterior plafond.In type 1 fractures, the syndesmosis was disrupted in 100% of cases, although a proportion only involved the posterior syndesmosis. In type 2 posterior malleolar fractures, there was a variable medial injury with mixed avulsion/impaction etiology. In type 3 posterior malleolar fractures, most fibular fractures were either a high fracture or a long oblique fracture in the same fracture alignment as the posterior shear tibia fragment. Most medial injuries were Y-type or posterior oblique fractures. This fracture pattern had a low incidence of syndesmotic injury.The value of this approach was that by following the pathomechanism through the ankle, it demonstrated which other structures were likely to be damaged by the path of the kinetic energy. With an understanding of the pattern of associated injuries for each category, a surgeon may be able to avoid some pitfalls in treatment of these injuries.Level III, retrospective comparative series.

We conducted an investigation into the relative associations of magnetic resonance imaging (MRI)-defined pathologic features of the spring ligament and/or tibialis posterior tendon with radiographic evidence of a planovalgus foot position. A total of 161 patient images (MRI and plain radiographs) obtained from the foot and ankle clinic (2008 to 2011) were retrospectively reviewed. All 161 patients (64 male and 97 female; mean age 45.9 years, range 18 to 86) were included in the analysis. Lateral weightbearing radiographs were analyzed for the talo-first metatarsal angle ≥ 5°, calcaneal pitch ≤ 20°, and talocalcaneal angle ≥ 45°. A positive finding for ≥ 1 measurements identified a radiographic planovalgus position of the foot. The radiographic deformity was analyzed against the MRI evidence of either spring ligament or tibialis posterior tendon pathologic features for significance (p < .05). Evidence of a spring ligament abnormality was strongly associated with a planovalgus foot position, reaching high levels of statistical significance in all 3 categories of radiographic deformity (odds ratio 9.2, p < .0001). Abnormalities of the tibialis posterior tendon failed to demonstrate significance, unless grade I changes were excluded, and grade II and III appearances were analyzed in isolation (odds ratio 2.9, p = .04). Although absolute causal relationships were not tested, this investigation has clearly demonstrated that MRI-defined abnormalities of the spring ligament complex are possibly of at least equal importance to tibialis posterior dysfunction for the presence of a moderate to severe radiographic planovalgus foot position.

The authors aim to present the common MRI appearances of surgically proven spring ligament tears as minimal radiological literature exists regarding injury to this increasingly important structure.Our retrospective review identified a treatment group comprising 13 cases of surgically proven spring ligament injury and a 96-patient comparison group. All patients underwent standard musculoskeletal MRI sequences of the foot and ankle. Images were reviewed by a registrar-grade orthopedic surgeon and a consultant musculoskeletal radiologist for abnormalities of the spring ligament complex.MRI findings in relation to surgically proven injury of the superior-medial portion of the spring ligament included proximal thickening5 mm in 92 % and distal thinning2 mm in 85 % of proven injures to the spring ligament complex. Common abnormalities of the medio-plantar portion comprised ligament thickening7 mm in 31 % and intra-substance signal heterogenicity demonstrated in 38 % of cases.The complex orientation of the medio-plantar ligament makes its evaluation unreliable due to the difficulty obtaining diagnostic quality imaging and our inability to correlate MRI findings in this portion of the ligament with surgically proven injury. However, MRI abnormalities of the superior-medial ligament are consistent, reproducible, and correlate with surgical pathology. As our incomplete understanding of the flexible flatfoot deformity evolves, our ability to recognize injury to the spring ligament may encourage novel surgical treatments looking to incorporate its repair or reconstruction into deformity correction.

Background. Enhanced recovery (ER) for elective total hip or total knee replacement has become common practice. The aim of this study is to evaluate the impact of ER on transfusion rates and incidence of venous thromboembolism (VTE). Methods. A comprehensive review was undertaken of all patients who underwent primary hip or knee arthroplasty surgery electively between January 2011 and December 2013 at our institution. ER was implemented in August 2012, thus creating two cohorts: the traditional protocol (TP) group and the ER group. Outcome measurements of length of stay, postoperative transfusion, thromboembolic complications, and number of readmissions were assessed. Main Findings. 1262 patients were included. The TP group contained a total of 632 patients and the ER group contained 630 patients. Postoperative transfusion rate in the ER group was reduced with 45% (P≤0.05). There was no statistical difference in postoperative VTE complications. The length of stay was reduced from 5.5 days to 4.8 days (P<0.05). Conclusions. There was no difference in the number of readmissions. ER has contributed to a significant decrease in transfusions after elective arthroplasty surgery, with no increase in the incidence of thromboembolic events. Furthermore, it has significantly reduced inpatient length of stay.

Patient reported outcome measures are becoming more popular in their use. Retrospective scoring is not yet a validated method of data collection but one that could greatly decrease the complexity of research projects. We aim to compare preoperative and retrospective scores in order to assess their correlation and accuracy.36 patients underwent elective foot and ankle surgery. All patients were scored preoperatively using the SF-12 (including both the physical and mental subsets) and FFI. Patients then recorded both PROMs at the 3-month follow up (av. 139 days). Results were then analyzed for statistical significance.36 patients (av. age 54.6): completed both sets of questionnaires. There were 15 hindfoot and 21 forefoot procedures. No retrospective scores were identical. The mean percentage difference between the preoperative scores was -7.9% (-17.3 to 1.6%, 95% CI) for Physical Component of SF12, -3.2% (-10.3 to 3.9%, 95% CI) for mental component of SF12 and 40.7% (25.3 to 56.1%, 95% CI) for FFI. This retrospective accuracy was statistically significant (p0.001). When the scores were plotted against each other, the outcome measurements showed positive correlations (Physical SF 12 p=0.48, Mental SF 12 p=0.80 and FFI p=0.81). With both PROMs mean percentage differences combined, patients undergoing hindfoot procedures (3.5%; -5.0 to 12.1%, 95% CI) were more accurate with retrospective scoring than their forefoot counterparts (17.5%; 5.0 to 30.0%, 95% CI). This was not statistically significant (p=0.07). Using regression analysis, we found no significant statistical difference in the retrospective accuracy when compared against both time to retrospective scoring and the outcome measure at 3 months post operatively.Retrospective scoring appears to lack accuracy when compared to prospective methods. However, our data shows the SF12 is recalled more accurately than the FFI (p0.001) and both the mental and physical components are recalled to within 10% of the pre-operative score. These results show patients tend to recall their symptoms at a worse level preoperatively than originally described, especially those with forefoot problems.

Category: Ankle Introduction/Purpose: There is an increasing acceptance that the clinical outcomes following posterior malleolar fractures are less than satisfactory. In creating a treatment guiding classification and algorithm, we report our results in a system change in management of posterior malleolar fractures in our unit. Methods: All fractures were classified according to Mason and Molloy classification (Foot Ankle Int. 2017 Nov;38(11):1229-1235) based on CT scans obtained pre-operatively. This dictated the treatment algorithm. Type 1 fractures underwent syndesmotic fixation. Type 2A fractures underwent ORIF through a posterolateral incision, and type 2B and 3 fractures underwent ORIF through a posteromedial incision. The patient remained NWB for 6 weeks postoperative. Data was collected prospectively from December 2014 to July 2017. Results: Patient-related outcome measures were obtained in 50 patients with at least 1 year follow up (mean 18 months). The overall OMAS score for all posterior malleolar fractures in this cohort was 74.1 (range 35-100). According to Mason and Molloy classification, the mean OMAS for type 1 was 75.9 (Range 30-100), type 2A 75.0 (range 35-100), type 2B 74.0 (range 55-100) and type 3 70.5 (Range 35-100). Using one way ANOVA test, there was no significant difference (p=.886) between groups or within groups. There was a trend, however, that the lower the Mason and Molloy classification had higher OMAS outcomes. The overall 1-year EQ-5D index for this cohort was 0.88 (SD 0.22). The average visual analogue score for this patient group was 77.5 (SD 26.2). Conclusion: We have been able to demonstrate an improvement in functional scores for all posterior malleolar fractures with the treatment algorithm applied using the Mason and Molloy classification. This is compared to our previous study where traditional posterior malleolar management was undertaken. Our OMAS scores have now improved to what would be expected from unimalleolar fractures, illustrating the importance of understanding the injury mechanism and patterns of injury. Mason and Molloy type 3 fractures have marginally poorer outcomes, which correlates with a more significant injury.

The term scarf osteotomy was first used by Weil when presenting his results from more than 1000 cases. Scarf is a carpentry term describing beveling the ends of 2 pieces of wood and securely fastening them so that they overlap to create one continuous piece. This technique was popularized by Weil and Barouk as a versatile method of correcting hallux valgus while maintaining the blood supply to the metatarsal head. It also has rigid fixation, allowing early mobilization. This article addresses the surgical technique of the scarf osteotomy together with the results and complications of hallux valgus correction.
