Adjusting an external fixator can be a daunting process for patients. Despite comprehensive training, patients often request supervision for the initial adjustments which may result in a prolonged hospital stay. Following the introduction of telemedicine during the pandemic we believed that this could be utilised to support patients with their fixator adjustments. A quality improvement project was implemented to assess and evaluate a change in practice from existing Face to Face support to a telemedicine format. The aim of the project was to reduce median length of stay (LOS). The telemedicine platform was introduced in our unit from April 2021 with the change in practice. Using the life QI platform, run charts were used to record the numbers of patients whose LOS was 4 days or less. Median LOS was assessed prior to and following introduction of the telemedicine platform. Service user experience with telemedicine as well as overall training and education by the CNS team was sought through on-line questionnaires.Introduction

The FitBone lengthening nail (Orthofix UK) is an intramedullary device licensed for the lengthening of long bones in adults in the UK. It contains a motor powered by electricity transmitted via an induction coil placed underneath the skin. It was developed in Germany two decades ago but uptake in the UK has only started more recently. The aim of this study was to review the first cohort of FitBone lengthening nails in a unit with significant experience of other lengthening nails (including PRECICE and Stryde). Demographic, clinical and radiological data was prospectively collected on all FitBone cases starting in February 2022. Accuracy of lengthening rate, patient satisfaction and implant issues were all considered. Complications and learning points were recorded and discussed by the multidisciplinary team involved in the patients care.Introduction

Patients undergoing limb reconstruction surgery often face a challenging and lengthy process to complete their treatment journey. The majority of existing outcome measures do not adequately capture the patient-reported outcomes relevant to this patient group in a single measure. Following a previous systematic review, the Stanmore Limb Reconstruction Score (SLRS) was designed with the intent to address this need for an effective instrument to measure patient-reported outcomes in limb reconstruction patients. We aim to assess the face validity of this score in a pilot study. The SLRS was designed following structured interviews with several groups including patients who have undergone limb reconstruction surgery, limb reconstruction surgeons, specialist nurses, and physiotherapists. This has subsequently undergone further adjustment for language and clarity. The score was then trialled on ten patients who had undergone limb reconstruction surgery, with subsequent structured questioning to understand the perceived suitability of the score.Aims
Methods
The use of intramedullary lengthening devices is becoming increasingly popular. There are no published data regarding the incidence of venous thromboembolism following intramedullary lengthening and no reports or guidance for current practices on use of thromboprophylaxis. Following a case of post-operative deep vein thrombosis in our institution, we felt that it is important to assess best practice. We conducted this survey to collect data that would describe current practice and help guide consensus for treatment. We have identified surgeons across the UK that perform intramedullary lengthening through the British Limb Reconstruction Society membership and a Precise Users database. Surgeons were contacted and asked to respond to an online survey (SurveyMonkey - SVMK Inc.). Responses to thromboprophylaxis regimes employed in their practice and cases of venous thromboembolism were collated.Introduction

Muscle stiffness and joint contractures are common complications of limb lengthening. Authors have demonstrated less permanent soft tissue complications with intramedullary lengthening than external fixation. Our aim was to evaluate the joint response following intramedullary femoral lengthening and need for physiotherapy and alteration to rate/rhythm of lengthening. A retrospective review of documentation for all femoral Precice nails in our centre inserted between 2012 and 2017. This involved 98 nails (68 antegrade, 30 retrograde) in 88 patients (59 males, 29 females) with a mean age of 32 years (range 12–69 yrs). We excluded cases where there was no documentation regarding Range of Movement (ROM). Bilateral lengthenings were recorded as separate cases. This left 50 antegrade, 16 retrograde cases with hip ROM data and 55 antegrade, 26 retrograde cases with Knee ROM data.Introduction
Method
Patients undergoing femoral lengthening by external fixation
tolerate treatment less well when compared to tibial lengthening.
Lengthening of the femur with an intramedullary device may have
advantages. We reviewed all cases of simple femoral lengthening performed
at our unit from 2009 to 2014. Cases of nonunions, concurrent deformities,
congenital limb deficiencies and lengthening with an unstable hip
were excluded, leaving 33 cases (in 22 patients; 11 patients had
bilateral procedures) for review. Healing index, implant tolerance
and complications were compared.Aims
Patients and Methods
Several low energy osteotomy techniques are described in the literature but there is limited evidence comparing healing indices. We present a retrospective review of two techniques to evaluate an optimum method. Two cohorts of patients underwent osteotomy of the tibia using a Gigli saw (n=15) or DeBastiani corticotomy (n=12) technique. Indications for surgery included limb lengthening and bone transport for defect reconstruction with a minimal distraction of 2 cm. The patient radiographs were anonymised and the regenerate assessed by the two senior authors who were blinded to the osteotomy type. Bone quality was recorded along the anterior, posterior, medial and lateral cortices, graded 1–5 from absent to full consolidation over time in frame. The time to 3 cortices healed/regenerate length was calculated. The time to consolidation of the anterior, posterior, medial and lateral cortices were compared. The mean 3 cortices index in the Gigli group was 2.0 months/cm and in the DeBastiani group 1.8 months/cm, This was not a significant difference. In both groups anterior bone formation was slower, and in 50% and 33% of the Gigli and DeBastiani groups respectively the anterior cortex did not fully heal by the time of frame removal.Method:
Results:
The Exogen Ultrasound Device is licensed for fracture non-union under NICE guideline MTG-12. Reimbursement is offered if there is no fracture union after 250 days of treatment as per manufacturer guidelines. Quoted healing rates vary between 62% and 100%: we compare our results to these. A retrospective audit of all patients who received Exogen for long bone non-union was undertaken. The indication, duration of treatment, fracture outcome and compliance with the recommended treatment pathway were recorded.Background:
Method:
External fixators are not as well tolerated around the femur when compared to the tibia. Lengthening with an intramedullary device is therefore attractive. We reviewed all cases of femoral lengthening performed at our unit from 2007 to 2014. Cases of non-unions, concurrent deformities, congenital limb deficiencies and lengthening with an unstable hip were excluded. This left 33 cases for review. Healing index, implant tolerance and complications were compared.Background:
Method:
Leg length discrepancy related to absence of the femoral head with proximal migration of the femur presents a treatment dilemma. Late sequelae of neonatal hip sepsis and chronic hip dislocation due to developmental dysplasia are the most common causes. Traditional teaching dictates that the hip is stabilised prior to limb lengthening. Reconstructive options alter the shape of the proximal femur which complicates future surgery. We retrospectively reviewed 3 cases of femoral lengthening with an ‘unstable’ hip without prior stabilization. The aetiology was neonatal hip sepsis in 2 cases and chronic hip dislocation due to developmental dysplasia in 1 case. Lengthening was performed with the use of a retrograde Precice lengthening nail.Background:
Methods:
Pin site care in external fixation remains a major challenge. The ideal dressing regime still remains controversial as does the type of dressing. We present an audit following the use of a sponge compression dressing in comparison to previously used sterile gauze. All pins and wires were inserted using a standardised technique. Dressings were applied during surgery to prevent haematoma formation. The new sponge dressing was applied to the wire or half-pin sites and compressed to the skin by either pierced tubing over the wire or clips at the end of the procedure. Dressings were changed weekly unless the pin sites were discharging serous fluid or frankly infected, when they were changed as required. The pin sites were evaluated for evidence of infection or irritation using the good, bad or ugly grading system. Each evaluation was performed by two of the authors on two separate occasions to assess the inter- and intra-observer error. The results were compared to those previously reported using sterile gauze as the pin site dressing. 1035 pin sites were assessed. 985 pin sites were graded as “good” (95.2%), 49 “bad” (4.7%) and 1 “ugly”. The kappa values demonstrated excellent inter- and intra-observer correlation, 0.892 and 0.905 respectively. The previous study using gauze reported 600 pin sites with 514 graded “good” (85.7%), 80 “bad” (13.3%) and 6 “ugly” (1%). The use of compression sponge dressing appears to reduce the rate of pin site irritation and infection. Further anecdotal evidence by patients who have undergone surgical treatment using both techniques demonstrated a preference for the sponge dressings due to ease of dressing change and general comfort once applied. We therefore would recommend this type of dressing in the use of external fixation.
We present the results of a new non-invasive lengthening nail enabling accurate control of the lengthening process and joint rehabilitation. The use of intramedullary lengthening nails have gained popularity as they reduce common complications associated with external fixators, including infection, joint stiffness, bone regenerate deformity, late fracture and patient implant acceptance. Current nails however are associated with complications including implant breakage, mechanical failure, runaway nail and requiring MUA to restart or obtain segment lengthening. The Precice nail incorporates magnet technology with a hand held device allowing non-invasive lengthening. The nail is also reversible allowing shortening if required. Physiotherapy can continue throughout treatment to maintain joint range of motion without concern of uncontrolled nail runaway. The lengthening is axial reducing shear/torsional forces on the regenerate. The lengthening of 4 femora was undertaken in 3 patients, mean age 34 yrs for post-traumatic shortening and short stature. A standard technique included an Ilizarov corticotomy followed by a 6 day latent period. Patients were mobilised partial weight bearing and knee range of motion maintained. The femora were lengthened one third of a millimetre three times per day. Radiographic and clinical review was performed every 2 weeks.Introduction
