Introduction. Previous studies have shown the potential for virtual reality (VR) immersion as a promising technique for pain and anxiety management. The aim of our study was to evaluate the feasibility of VR in the management of pain and anxiety during post-op external fixator care procedures. Method. This study involved patients aged 5-21 years following limb lengthening/reconstruction surgery with an external fixator. Aqua VR application from the KindVR® was utilized for this study. Subjects were seen during the first four postoperative visits and assigned to a ‘VR-first’ or ‘no-VR-first’ group. Visits alternated between VR immersion and no VR immersion during care procedures. The study endpoints (pain and anxiety levels) were assessed before, during, and after procedures using the Wong-Baker Faces (FACES) and Children's Fear Scale, respectively. Proxy scores for pain and anxiety were also obtained from parents or legal guardians and providers. Result. A total of 29 patients (16 male and 13 female) were evaluated. The mean age at enrollment was 14.4 ± 2.2 years for group 1 and 14.7 ± 4.0 years for group 2. The median number of pin sites was 7. Anxiety scores were consistently higher during the non-VR immersion experience compared to the VR immersion visits. The pain and anxiety scores were significantly lower in the ‘VR-first’ group during the non-VR immersion study visits compared to patients in the ‘no-VR-first’ group. This observation was also consistent with survey findings among the parent proxies and providers. Conclusion. VR immersion is associated with lower anxiety scores for pin-site care procedures. VR immersion at the first post-operative visit following limb reconstruction surgery was also associated with lower pain and anxiety scores during subsequent non-VR immersion visits

Introduction. The non-union of long bones poses a substantial challenge to clinicians and patients alike. The Ilizarov fixation system and Limb Reconstruction System (LRS), renowned for their versatility in managing complex non-unions. The purpose of this retrospective study was to assess the outcomes of acute docking with the bone peg-in-bone technique for the management of non-unions of long bones. The study seeks to evaluate its effectiveness in achieving complete bony union, preserving limb length and alignment, correcting existing deformities, and preventing the onset of new ones. Method. A retrospective analysis of 42 patients was done with infected and non-infected non-unions of long bones who received treatment at a tertiary care hospital between April 2016 to April 2022. We utilized the Association for the Study and Application of Methods of the Ilizarov (ASAMI) scoring system to assess both bone and functional outcomes and measured mechanical lateral distal femoral angle (mLDFA) for the femur and the medial proximal tibial angle (MPTA) for the tibia. Result. In our retrospective study involving 42 patients, a total of 30 patients had post debridement gap of >2 cm and average gap of 4.54 cm (range 1 – 13 cm) and therefore underwent corticotomy and lengthening. The average external fixation time was 6.52 (range 4 – 11 months) and average external fixation index of 2.08 (range 0.4 – 4.5 months/cm). The ASAMI scoring system showed bone result of 38 excellent, 3 good and 1 fair. Functional result of 40 excellent and 2 good outcomes. The post op mLDFA and MPTA were in normal range except in 3 patients which not statistically significant. Conclusion. In conclusion, the use of acute docking provides several advantages such as promoting early fracture healing, increasing stability, shortening treatment time, reducing the number of surgical procedures and reduced number of complications

The TL Hex (Orthofix) is a relatively new hexapod frame system that we have been using at our institution since August 2013 to treat acute fractures and correct tibial and femoral deformity. We report our initial experience of 48 completed treatments with this novel system in 46 patients and discuss illustrative cases. For acute fracture, 30 patients (24 male, 7 female) required framing with a mean age of 43 years (range 19–80). One patient underwent bilateral framing. The tibia was involved in all cases. In two cases, the femur also required framing. Open fractures occurred in 13 cases (43.3%). For elective limb reconstruction, 16 patients (14 male, two female) required framing with a mean age of 35 years (range 16–67). One patient underwent bilateral framing. The tibia was involved in all but one case, which affected the femur. Surgical indications included congenital deformity in four cases, malunion in eight cases, non-union in three cases and chronic infection in two cases. For acute fractures, the mean frame time was 164 days (range 63–560) and all but one fracture achieved union. Complications included pin, wire or strut failure requiring adjustment (three patients) and pin site infection (six patients). Three patients are being considered for residual deformity correction or treatment of non-union. In the elective limb reconstruction group, mean frame time was 220 days (range 140–462). All treatments successfully achieved deformity correction and bone union. Complications included two pin site infections. There was no evidence of recurrence of infection in the two osteomyelitis cases. In conclusion, the TL Hex frame system appears to be a safe and reliable tool for limb reconstruction. We have observed acceptable frame times, low complication rates and almost 100% bony union

Objectives. Fracture non-union poses a significant challenge to treating orthopaedic surgeons. These patients often require multiple surgical procedures. The incidence of complications after Autologous Bone Graft (ABG) harvesting has been reported up to 44%. These complications include persistent severe donor site pain, infection, heterotopic ossification and antalgic gait. We retrospectively compared the use of BMP-7 alone in long bone fracture Non-union, with patients in whom BMP-7 was used in combination with the Autologous Bone Graft (ABG). Material and Methods. The databases of our dedicated Limb Reconstruction Unit were searched for patient with three common long bone fractures Non-unions (Tibia, Femur and Humerus). The patients who had intra-operative use of Bone Morphogenetic Protein (BMP-7) alone and in combination with ABG were evaluated. 53 Patients had combined use of ABG and BMP-7, and 65 patients had BMP-7 alone. Results. In the ABG and BMP-7 group, the union rate for femoral (n=18) Non-unions was 83%, for humeral (n=16) Non-unions 81%, and for tibia (n=19) Non-unions it was 47%. In the BMP-7 alone group, 83% of the femoral (n=12) Non-unions, 87% of the humeral (n=16) and 56% of the tibial (n=37) Non-unions healed. The common risk factors for Non-union were comparable in both the groups and included location and nature (open vs closed) of fracture, infection, smoking and NSAIDs use. The average time to union in ABG+BMP-7 group was 8.1 months (range 3-30 months) and in BMP-7 alone group it was 7.2 months (range 3-24 months). Conclusion. Autologous Bone Grafting has a pivotal role in limb reconstruction surgery but its indication should be carefully evaluated in view of considerable morbidity associated with graft donor site. Our study did not show any significant difference in the union rates of common long bone fracture Non-unions treated with BMP-7 alone or with a combination of Autologous Bone Graft and BMP-7

Consequent upon a retrospective audit of all acute tibial nail patients within GRI in 2010, it was agreed, due to variable follow-up, imaging and requirement for secondary intervention, a standardised protocol for management of acutely nailed tibial fractures within GRI was to be established. Subsequently, a Nurse Led Tibial Nail Clinic commenced in July 201. The majority of consultants (11 of 13) devolving follow up of these patients to a protocol based algorithm designed on evidence based principles and consensus expert opinion. Aims were to standardise/improve management of tibial nail patients in terms of patient education, weight bearing, imaging, follow-up intervals and also coordinate secondary intervention via a single consultant with an interest in limb reconstruction/non union. A secondary goal was to achieve measureable outcome data for this subgroup of patients. All patients underwent post operative radiographs prior to discharge, review in clinic at 10 days for wound assessment, 6 weeks for physiotherapy and 12 weeks where standard AP and lateral tibial radiographs were repeated. Patients are discharged at 12 weeks if the radiographs confirm bony healing on three cortices or more and fractures are clinically united. If not, repeat x rays are undertaken at 20 weeks. A parallel consultant led limb reconstruction clinic is available to review patients failing to demonstrate satisfactory progression to union with secondary intervention instigated thereafter as appropriate. Since commencement of the Nurse Led Tibial Nail Clinic, 60 patients have been treated with a tibial nail, 44 managed in the Tibial Nail Clinic. The mean number of radiographs has reduced from 6.4 to 3.1 per patient to discharge. Clinic visits are reduced from 6.4 to 3.9 per patient to discharge. Non compliance is low with 4.6% of patients failing to attend. Secondary interventions have been low (13%), confirming a relatively benign course of healing for most patients treated with an IM nail for acute tibial fractures. There has been one non union, no deep infections, two nail removals and one DVT. A protocol based specialist nurse led clinic is safe for patients, cost effective for the NHS and gives increased opportunity for measuring outcome and improving care in a previously heterogenously managed group of patients

The implementation of knee arthrodesis has become synonymous with limb salvage in the presence of chronic sepsis and bone loss around the knee. This can be seen in failed trauma surgery or knee arthroplasty as an alternative to trans-femoral amputation. There is no prior literature assessing which factors affect knee arthrodesis using external fixation devices. Sixteen consecutive patients (four women and twelve men) made up of eleven infected knee implants, three internal fixations of the tibial following fractured tibial plateau as well as 2 infected native joints were identified. The mean age at initial surgery was 56 years (range 25 to 82 years). All procedures were performed under the direct supervision of the limb reconstruction teams using a standard protocol with either a Taylor spatial frame or Ilizarov frame. The patient records, microbiology results and radiographs of all patients who underwent knee arthrodesis at this institution between 1999 and 2010 were reviewed. Of the 16 patients in this study knee fusion occurred in eleven patients (69%). The five patients where arthrodesis failed all had significant bone loss on the pre-operative radiographs and confirmed at surgery. We found a relationship between a significant infection of the knee with MRSA and failure to fuse. Three of the five patients had MRSA isolated from inside the knee at some stage during their treatment. The five patients where fusion failed were on average older (mean age 63 years against 51 years) and had more extensive bone loss. Those who failed to fuse had more co-morbidities. We would conclude that where there is little or no bone loss, arthrodesis of the knee can be reliably achieved with the use of circular frame fixation. A greater number of negative factors also prolongs the amount of time spent in the external fixator. The presence of significant bone loss, infection, increased age and multiple co-morbidities requires careful evaluation and consideration of trans-femoral amputation as an alternative

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
