The aim of this study was to determine medium term functional outcomes in military casualties undergoing limb salvage for severe open tibia fractures, and compare them to trans-tibial amputees. Cases of severe open diaphyseal tibia fractures sustained in combat between 2006 – 2010 were contacted and interviewed. These results were compared to a similar cohort of 18 military patients who sustained a unilateral trans-tibial amputation in the same period. Forty-nine patients with 57 severe open tibia fractures met the inclusion criteria, of which 30 patients (61%) were followed-up. Ten of the 30 patients required revision surgery, 3 of which involved conversion to a circular frame. Twenty-two of the 30 patients (73%) recovered sufficiently to complete a basic military fitness test. The median physical component score of SF-36 in the limb salvage group was 46 (IQR 35–54) which was similar to the trans-tibial amputation cohort (p=0.3057, Mann-Whitney). There was no significant difference in the proportion of patients in either the amputation or limb salvage group reporting pain (p=0.1157, Fisher's exact test) or with respect to SF-36 physical pain scores (p=0.5258, Mann-Whitney). This study demonstrates that medium term outcomes for military patients are similar following trans-tibial amputation or limb salvage following combat trauma

The aim of this study was to establish medium term outcomes in military casualties following severe open tibia fractures.

Cases from a previously published series were contacted and assessed with the SF-36 outcome tool. Their results were then compared to a similar study of military trans-tibial amputees.

Of the original data set of 49 patients, 30 patients were followed up and completed an SF-36 (61%) with a median follow-up of 4 years (49 months, IQR 397–63). Ten of the 30 required revision surgery, 3 of which involved conversion from initial fixation to a circular frame. Twenty-two of the 30 patients recovered sufficiently to complete a military basic fitness test. The median physical component of SF-36 in the tibia fracture group was 46 (IQR 35–54) which was similar to the trans-tibial amputation cohort (p=0.3057, Mann-Whitney). Similarly there was no difference in mental component scores (p=0.1595, Mann-Whitney). There was no significant difference in the proportion of patients in the amputation or fracture group reporting pain (p= 0.1157, Fisher's exact test) or with respect to SF-36 physical pain scores (p=0.5258, Mann-Whitney).

We present the patient reported outcomes following combat open tibia fracture and show that they are similar to those achieved after trans-tibial amputation.

Aims. Complex fractures of the femur and tibia with associated severe soft tissue injury are often devastating for the individual. The aim of this study was to describe the two-year patient-reported outcomes of patients in a civilian population who sustained a complex fracture of the femur or tibia with a Mangled Extremity Severity Score (MESS) of ≥ 7, whereby the score ranges from 2 (lowest severity) to 11 (highest severity). Methods. Patients aged ≥ 16 years with a fractured femur or tibia and a MESS of ≥ 7 were extracted from the Victorian Orthopaedic Trauma Outcomes Registry (January 2007 to December 2018). Cases were grouped into surgical amputation or limb salvage. Descriptive analysis were used to examine return to work rates, three-level EuroQol five-dimension questionnaire (EQ-5D-3L), and Glasgow Outcome Scale-Extended (GOS-E) outcomes at 12 and 24 months post-injury. Results. In all, 111 patients were included: 90 (81%) patients who underwent salvage and 21 (19%) patients with surgical amputation. The mean age of patients was 45.8 years (SD 15.8), 93 (84%) were male, 37 (33%) were involved in motor vehicle collisions, and the mean MESS score was 8.2 (SD 1.4). Two-year outcomes in the cohort were poor: six (7%) patients achieved a GOS-E good recovery, the mean EQ-5D-3L summary score was 0.52 (SD 0.27), and 17 (20%) patients had returned to work. Conclusion. A small proportion of patients with severe lower limb injury (MESS ≥ 7) achieved a good level of function 24 months post-injury. Further follow-up is needed to better understand the long-term trajectory of these patients, including delayed amputation, hospital readmissions, and healthcare utilization.

Background. The decision to attempt limb salvage vs to amputate in a significant traumatic limb injury is based on patient´s best predicted outcome. When amputation cannot be avoided the aim is to provide a pain free limb whilst preserving the soft tissue and limb length. Methods. Retrospective study covering 5 years (2011–2016), all the trauma patients requiring lower limb amputation (LLA) included. Demographics, mechanism, type of injury, amputation type, cause and level, theatre trips for stump management were analysed. Results. 19 patients aged 27–93 included. RTC was the leading cause (47%) of LLA. Amputation type: traumatic, caused by the injury itself (31.5%) acute surgical, amputation performed in a limb threatening injury (37%); 72% of them had vascular compromise delayed amputations after failure of limb salvage surgery (31.5%); failed soft tissue coverage and poorly functioning limb were the lead cause (33% each) Type of injury: open fractures (89%), isolated to a limb segment (53%). One level/extended level=9/10 patients. More than 50% of initial amputations were extended with multiple subsequent theatre trips (33/10 patients) for stump management. Conclusions. It was difficult to predict the patients needing an extended amputation. Early MDT and prosthetic rehab service involvement is crucial in LLA decision. When consenting patients for LLA consider a 50% change to extend the initial level of amputation with subsequent theatre trips

Aims. Open fractures of the tibia are a heterogeneous group of injuries that can present a number of challenges to the treating surgeon. Consequently, few surgeons can reliably advise patients and relatives about the expected outcomes. The aim of this study was to determine whether these outcomes are predictable by using the Ganga Hospital Score (GHS). This has been shown to be a useful method of scoring open injuries to inform wound management and decide between limb salvage and amputation. Methods. We collected data on 182 consecutive patients with a type II, IIIA, or IIIB open fracture of the tibia who presented to our hospital between July and December 2016. For the purposes of the study, the patients were jointly treated by experienced consultant orthopaedic and plastic surgeons who determined the type of treatment. Separately, the study team (SP, HS, AD, JD) independently calculated the GHS and prospectively collected data on six outcomes for each patient. These included time to bony union, number of admissions, length of hospital stay, total length of treatment, final functional score, and number of operations. Spearman’s correlation was used to compare GHS with each outcome. Forward stepwise linear regression was used to generate predictive models based on components of the GHS. Five-fold cross-validation was used to prevent models from over-fitting. Results. The mean follow-up was 11.4 months (3 to 31). The mean time to union was 9.7 months (3 to 21), the mean number of operations was 2.8 (1 to 11), the mean time in hospital was 17.7 days (5 to 84), the mean length of treatment was 92.7 days (5 to 730), the mean number of admissions was 1.7 (1 to 6), and the mean functional score (Lower Extremity Functional Score (LEFS)) was 60.13 (33 to 80). There was a significant correlation between the GHS and each of the outcome measures. A predictive model was generated from which the GHS could be used to predict the various outcome measures. Conclusion. The GHS can be used to predict the outcome of patients who present with an open fracture of the tibia. Our model generates a numerical value for each outcome measure that can be used in clinical practice to inform the treating team and to advise patients.

Aims. The management of open lower limb fractures in the United Kingdom has evolved over the last ten years with the introduction of major trauma networks (MTNs), the publication of standards of care and the wide acceptance of a combined orthopaedic and plastic surgical approach to management. The aims of this study were to report recent changes in outcome of open tibial fractures following the implementation of these changes. Patients and Methods. Data on all patients with an open tibial fracture presenting to a major trauma centre between 2011 and 2012 were collected prospectively. The treatment and outcomes of the 65 Gustilo Anderson Grade III B tibial fractures were compared with historical data from the same unit. . Results. The volume of cases, the proportion of patients directly admitted and undergoing first debridement in a major trauma centre all increased. The rate of limb salvage was maintained at 94% and a successful limb reconstruction rate of 98.5% was achieved. The rate of deep bone infection improved to 1.6% (one patient) in the follow-up period. . Conclusion. The reasons for these improvements are multifactorial, but the major trauma network facilitating early presentation to the major trauma centre, senior orthopaedic and plastic surgical involvement at every stage and proactive microbiological management, may be important factors. . Take home message: This study demonstrates that a systemised trauma network combined with evidence based practice can lead to improvements in patient care.

Background. Extendable proximal femoral replacements(PFR) are used in children with bone tumours in proximity to the proximal femoral physis, previously treated by hip disarticulation. Long-axis growth is preserved, allowing limb salvage. Since 1986, survival outcomes after limb salvage and amputation have been known to be equal. Method. Retrospective review of all patients <16years undergoing extendable PFR at Royal National Orthopaedic Hospital (UK) between 04/1996 and 01/2006, recording complications, failures, procedures undertaken and patient outcomes. Results. 8 patients (mean age 8.9±3 years) underwent extendable PFR for Ewing's Sarcoma(5), Osteosarcoma(1), Chondrosarcoma(1) and rhabdomyosarcoma(1). 2 primary PFRs failed (infection of unknown source & local recurrence, both at 26months); 2 required revision for full extension (1 became infected at revision, requiring 2 stage revision). 3 patients had the original prosthesis in situ at last follow-up (mean 7.2;range 3–10.5years). 1 patient had no implant complications, but died (neutropaenic sepsis) 63 days after implant insertion. 2 were treated for recurrence but disease free at last review. 5 were continuously disease free. 5 patients were lengthened a mean 3.7cm; 2 were not lengthened.1 had incomplete data. 5 patients suffered subluxation/dislocation (mean 15.6months), 3 recurrently. Each underwent a mean 1.6 open & 1.4 closed procedures for the displaced joint. 3 patients had 4 open reductions and acetabuloplasties and 2 patients were converted to THR, with 3 major complications: 2 sciatic nerve palsies and 1 (THR) infection. The 5th patient was due for acetabuloplasty but had hip disarticulation for recurrence. Acetabular erosion occurred in 3; 2 were revised to THR (3.5 & 6.8years). 3 patients suffered peri-prosthetic supracondylar fracture (treated conservatively). 5 patients were revised to THR (mean 5.9years): 2 for dislocation, 2 for acetabular erosion & 1 for infection. 1 underwent amputation and another died. Only 1 surviving implant was not converted to THR: this patient had progressive acetabular erosion at 10.5 years & will eventually require THR. The amputee had poor hip function prior to disarticulation but went on to become an international Paralympic sportsman and had very good function 11.4 years post-disarticulation. 3 patients had fixed hip adduction deformity. 1 was isolated and treated with adductor tenotomy, whilst 2 were associated with knee flexion deformity (one required in-patient physiotherapy; the other prosthetic shortening). Conclusions. Extendable PFR permits limb salvage with psychological & functional benefits, but complications are common and some are specific to PFR. Surgery for these may result in further complications. Patients should be warned of the high conversion rate to THR. All the above should be borne in mind when selecting patients. As illustrated above, functional outcome is sometimes better with amputation

Purpose. To examine the management and outcome of patients suffering complex paediatric lower limb injuries with bone and soft tissue loss. Method. A retrospective review was conducted identifying patients from our trauma database. Inclusion criteria were age (4–17 years) and open lower-limb trauma. Outcome measures included time to soft tissue coverage, surgical techniques, trauma impact scores, health-related quality of life, union and complication rates. Results. We identified 26 patients. 24 patients had open tibia fractures including 10 patients with bone loss. In 9 patients primary skin closure was achieved by acute shortening. 17 patients required soft tissue coverage including 14 free vascularised muscle flaps (89% within 48 hours). The surgical techniques applied were: circular fine wire frame (16), external fixateur (5) and open reduction internal fixation (5). Median follow up time was 8 (3–45) months. The trauma impact scores showed one in three patients were at risk of PTSD. All fractures went on to unite over a median time of 4.2 (2–9) months. No deep infections occurred. Conclusion. All our patients had limb salvage, fracture union and near normal levels of physical scores in the short term. Close psychological follow up is advisable to minimise the risk of PTSD

Although it is widely accepted that grade IIIB open tibial fractures require combined specialised orthopaedic and plastic surgery, the majority of patients in the UK initially present to local hospitals without access to specialised trauma facilities. The aim of this study was to compare the outcome of patients presenting directly to a specialist centre (primary group) with that of patients initially managed at local centres (tertiary group). We reviewed 73 consecutive grade IIIB open tibial shaft fractures with a mean follow-up of 14 months (8 to 48). There were 26 fractures in the primary and 47 in the tertiary group. The initial skeletal fixation required revision in 22 (47%) of the tertiary patients. Although there was no statistically-significant relationship between flap timing and flap failure, all the failures (6 of 63; 9.5%) occurred in the tertiary group. The overall mean time to union of 28 weeks was not influenced by the type of skeletal fixation. Deep infection occurred in 8.5% of patients, but there were no persistently infected fractures. The infection rate was not increased in those patients debrided more than six hours after injury. The limb salvage rate was 93%. The mean limb functional score was 74% of that of the normal limb. At review, 67% of patients had returned to employment, with a further 10% considering a return after rehabilitation. The times to union, infection rates and Enneking limb reconstruction scores were not statistically different between the primary and tertiary groups. The increased complications and revision surgery encountered in the tertiary group suggest that severe open tibial fractures should be referred directly to specialist centres for simultaneous combined management by orthopaedic and plastic surgeons

Extracorporeal irradiation and re-implantation of a bone segment is a technique employed in bone sarcoma surgery for limb salvage in the setting of reasonable bone stock. There is neither consensus nor rationale given for the dosage of irradiation used in previous studies, with values of up to 300Gy applied. We investigated the influence of extracorporeal irradiation on the elastic and viscoelastic properties of bone. Bone specimens were extracted from mature cattle and subdivided into thirteen groups; twelve groups exposed to increasing levels of irradiation and a control group. The specimens, once irradiated, underwent mechanical testing in saline at 37°C. Mechanical properties were calculated by experimental means which included Young's Modulus, Poisson's Ratio, Dissipation Factor, Storage Modulus, Loss Modulus and Dynamic Modulus. These were all obtained for comparison of the irradiated specimens to the control group. We found there to be a statistically significant increase in Poisson's ratio after increasing irradiation doses up to 300Gy were applied. However, there was negligible change in all other mechanical properties of bone that were assessed. Therefore, we conclude that the overall mechanical effect of high levels of extracorporeal irradiation (300Gy) is minute, and can be administered to reduce the risk of malignancy recurrence

Aims

Ankle fractures are common injuries and the third most common fragility fracture. In all, 40% of ankle fractures in the frail are open and represent a complex clinical scenario, with morbidity and mortality rates similar to hip fracture patients. They have a higher risk of complications, such as wound infections, malunion, hospital-acquired infections, pressure sores, veno-thromboembolic events, and significant sarcopaenia from prolonged bed rest.

Methods

A modified Delphi method was used and a group of experts with a vested interest in best practice were invited from the British Foot and Ankle Society (BOFAS), British Orthopaedic Association (BOA), Orthopaedic Trauma Society (OTS), British Association of Plastic & Reconstructive Surgeons (BAPRAS), British Geriatric Society (BGS), and the British Limb Reconstruction Society (BLRS).

Introduction. Dedifferentiated chondrosarcoma (D.C.) has a very poor prognosis. The efficacy of chemotherapy is still debated. Aim of this study was to evaluate the survival of patients with D.C. and to evaluate possible prognostic factors. Methods. Between 1990 and 2006, 109 patients were treated for D.C.: 55 males and 54 females, mean age of 59.6 years. In 81 cases tumor was located in the extremities and in 28 cases in the trunk. The most frequent dedifferentiation was in osteosarcoma (53.2%) followed by spindle cell sarcoma (21%), malignant fibrous histiocytoma (13.8%), fibrosarcoma (6.4%). All patients received surgery and mostly, limb salvage with tumor resection and implantation of a megaprosthesis or allograft (65 patients). Chemotherapy was given to 43 patients. Results. 16 patients (15.5%) were Ned at a mean followup of 10 yrs, 8 patients Ned1 after treatment of relapse, 1 patient AWD at 4.7 yrs, 77 patients DWD at a mean time of 1.6 yrs, 1 patient dead for other causes and 6 patients lost to followup were excluded. The overall survival of patients was 15%. There was significant difference in survival between patientens with D.C. of the trunk and those with D.C. of the extremities (p=0.0156). There was no significant difference in survival with chemoterapy and surgery or with surgery only (p=0.1115). Conclusion. The prognosis for patients with D.C. remains dismal. Surgery with wide margins is the principal treatment for this condition. There was no statistical evidence of any beneficial effect from chemotherapy

There are few reports on function after limb salvage surgery using the Ilizarov technique, and none that document the pattern of recovery or predict when maximum function returns. This prospective, longitudinal study documents the baseline functional abilities of 40 consecutive patients with nonunion of a fracture in the lower limb. Patients were studied for at least two and a half years following the completion of surgery. Function was measured by timed tests of functional performance and by the Toronto Extremity Salvage Score self-reported patient questionnaire. Recovery was slowest in the early stages after removal of the frame and greatest between six months and one year. Statistically significant improvement continued up to, but not beyond two years. This observation has important implications for the length of follow-up incorporated into the rehabilitation programmes for patients, predictions of patient status in regard to compensation and for the design of future studies to evaluate functional outcome

Introduction. Telangiectatic osteosarcoma (TOS) is a rare subtype of osteosarcoma. We review our experience to characterize its prevalence, treatment, relapse and survivorship at long term follow-up. Methods. Eighty-seven patients aged from 4 to 60 years (mean 20 years), were treated from 1985 to 2008. Lesions affected the femur (38), humerus (20), tibia (19), fibula (4), pelvis (3), foot (2) and radius (1). Eight patients had metastatic disease at diagnosis. Seventy-eight patients were treated with neoadjuvant chemotherapy with three or more drugs according to different protocols, nine had surgery as first treatment. Limb salvage surgery was performed in 71 cases, amputation in 14 and rotationplasty in one. One patient died before surgery. Prognostic factors were evaluated with Kaplan-Meier analysis. Results. At a mean follow-up of 8 years, overall survival was 81%, 65% and 65% at 2, 5 and 10 years respectively. Fifty-two patients were disease-free, three were alive with disease, twenty-nine died with disease and three died of other causes. Thirteen local recurrences were observed. Twenty-three patients developed lung (20) or bone (3) metastases. Pathologic fracture did not significantly influence survivorship. Prognostic influence of age of the patients was evaluated at three different cut-off (15, 20 and 25 years-old): younger patients had better survivorship, without statistical significance. Induced necrosis according to Huvos’ classification was significant at both univariate and multivariate regression Cox analysis (p=0.0001). Conclusion. TOS does not have a poor prognosis as previously reported in the literature. A high percentage of patients can be cured with neoadjuvant chemotherapy and surgery. In most patients, limb sparing surgery is possible and safe

Limb salvage after loss of bone and soft tissue may require many operations to obtain soft-tissue cover and bony continuity. We describe a fibula-flexor hallucis longus osteomuscular flap which can provide both soft tissue and bone in a single stage. The flap is based on the peroneal vessels and is covered by a split-thickness skin graft. We report the results in five patients with an average bone defect of 8.3 cm and soft-tissue and skin loss. All regained a normal gait on the donor side; four had clinical and radiological union with excellent soft-tissue cover, but one required later amputation due to diffuse coagulopathy. The flap provides free vascularised bone with muscle cover. It has a dependable, long pedicle with minimal morbidity at the donor site, and allows monitoring of the vascularity of the fibular graft

The reconstruction of lower limb defects after oncological reconstructions is still a problem in limb salvage surgery. Large bony defects need to be treated with sound and durable reconstructions. During recent decades, the life expectancy of patients affected with cancer has improved considerably because of advances in chemotherapy, immunotherapy, hormonal treatment and radiotherapy. This improvement requires greater reliability in the reconstructive procedure in order to avoid mechanical failure during prolonged survival of the patient. The author experience with modular megaprosthesis by Link (megasystem C) allowed us to present a rapid, effective and functional solution. From June 2001 to December 2007 225 patients have been operated with a megaprosthesis C for tumoral resection. The new megaprosthesis C by Link represents a wide-ranging system that can afford a large variety of reconstructions in the inferior limb, from very short replacement of 5 cm in proximal femur, to a total femur and proximal tibia replacement. Modularity is represented by 1 cm increase in length. The different options of cemented and not cemented stem may be used with intraoperative decision. In cemented stem a rough collar seals the osteotomy and prevents polyethylene debris from entering the femoral canal by inducing a scar tissue around the stem entrance (so-called purse-string effect). Moreover in patients with solitary lesions and very good prognosis an allograft-prosthesis composite can be performed with improved clinical results on walking and function. Of the 225 patients that underwent tumoral resection and reconstruction with a modular megaprosthesis approximately 43% (97 cases) were operated for metastatic disease. Among these cases 55 cases were proximal femoral recontructions, 39 cases were distal femoral reconstructions and 3 cases were proximal tibial reconstructions. All cases were performed with cemented stems. We experienced a 7% of postoperative infections, 2% of dislocations of proximal femoral prosthesis and 3% of mechanical failures. While infections and dislocation rates were in the average for this surgery, mechanical failures were relatively high. We should consider that in patients with relatively long resections and muscle deficiency the mechanical stress exerted on the prosthesis can explain this kind of mechanical failure. However the new design of morse tapers have annulled these problems

INTRODUCTION. Limb salvage surgery is a common treatment for patients who suffer from bone tumors. In the case of pelvic tumors this creates a challenge for the surgeon and the treatment remains controversial because the oncologic complications like local recurrence, dissemination and orthopaedic ones, like infection, haemorrhage, and mechanical problems of reconstructions Tumors affecting the acetabulum are a challenge for the surgeon because of the impact in the function of the extremity. There are many reconstruction techniques described in the literature like prosthesis, allograft systems, arthrodesis, etc…, but still there is not a gold standard due to the poor functional results at long term follow up, and the associated complications of all techniques. In this study we show the experience in our center on pelvic reconstructions after tumors affecting the acetabulum area (zone II). MATERIAL AND METHODS. We surgically treated 81 pelvic tumors from 1997 to 2009 following the Enneking and Dunham calssification attending to the localization of the tumor: Zone I 38 (iliac bone)Zone II 25 (acetabulum)Zone III 18 (pelvic branches)In zone II tumors we performed pelvic reconstruction in eight cases, with different type of prosthesis. In 5 cases we performed saddle prosthesis (group A) and in 3 cases we performed Coned-Stanmore Implants type prosthesis with sacro-iliac anchorage. The mean follow up of the serie was 3,5 years (1–6 years). In group A the mean follow up was 5 years and in group A and in group B the mean follow up was 1 year due to the recent implantation in our center of Coned type prosthesis for pelvic reconstruction. We evaluated our results with these two types of prosthesis. RESULTS. Oncologic: group A we had a local recurrence of 25% and 25% of the patients died. group B we had no cases of local or systemic recurrence and we didn't registered any death. Functional: In group A the patients showed local pain and difficulty to walk probably due to the change of the center of rotation of the hip and instability of the saddle prosthesis. In group B all patient's followed physical therapy programs without problems and were able to walk with crutches ten months after surgery. Complications:group A we had a 25% of perioperative infection and a 25% of dislocation of the prosthesis. In group B we did not have any of these complications. CONCLUSIONS. Saddle prosthesis mantain the length of the extremity and allow weight bearing but they do not give a good stability. Even if we only have one year follow up with this Coned prosthesis with sacro iliac anchorage we achieved much better functional results and a lower rate of complications

We studied the outcome and functional status of 33 patients with 34 severe open tibial fractures (Gustilo grade IIIb and IIIc). The treatment regime consisted of radical debridement, immediate bony stabilisation and early soft-tissue cover using a muscle flap (free or rotational). The review included standardised assessments of health-related quality of life (SF-36 and Euroqol) and measurement of the following parameters: gait, the use of walking aids, limb-length discrepancy, knee and ankle joint function, muscle wasting and the cosmetic appearance of the limb. Personal comments and overall patient satisfaction were also recorded. The mean follow-up was 46 months (15 to 80). There were 30 Gustilo grade IIIb fractures and and four grade IIIc fractures. Of the 33 patients, 29 had primary internal fixation and four, external fixation; 11 (34%) later required further surgery to achieve union and two needed bone transport procedures to reconstruct large segmental defects. The mean time to union was 41 weeks (12 to 104). Two patients (6.1%) developed deep infection; both resolved with treatment. The mean SF-36 physical and mental scores were 49 and 62 respectively. The mean state of health score for the Euroqol was 68. Patients with isolated tibial fractures had a better outcome than those with other associated injuries on both scoring systems. Knee stiffness was noted in seven patients (21%) and ankle stiffness in 19 (56%); 12 patients (41%) returned to work. Our results compare favourably with previous outcome measurements published for both limb salvage and amputation. All patients were pleased to have retained their limbs

Background/Aims. The development of extendable prostheses has permitted limb salvage surgery in paediatric patients with bone tumours in proximity to the physis. Prostheses are extended to offset limb length discrepancy as the child grows. Aseptic loosening (AL) is a recognised complication. The implant stem must fit the narrow paediatric medullary canal and remain fixed while withstanding growth and increasing physical demands. Novel designs incorporate a hydroxyapatite (HA) coated collar that manufacturers claim improves bony ongrowth and stability, providing even stress distribution in stem and shoulder regions and providing a bone-implant seal, resulting in decreased AL and prolonged survival. This study aims to assess whether there is a relationship between bony ongrowth onto a HA collar and AL. Hypothesis: Bone ongrowth onto the HA collar of extendable prostheses is associated with more stable fixation and less AL despite patient growth. Methods. Retrospective review of 51 primary partial femoral extendable prostheses implanted over 12 years from 1994–2006 (followed up to death at a mean of 2.5±2.2 years or last clinical encounter at a mean of 8.6 years) and 24 subsequent revisions, to ascertain failure rate and mode, together with a cohort study reviewing bony ongrowth onto the HA coated collar in 10 loose and 13 well fixed partial femoral, humeral and tibial implants. Patient growth was measured as a change in bone:implant-width ratio. Results. 21 (41.2%) primary femoral implants failed at a mean 42.8 months, 5 through AL. 1 secondary implant was revised for AL. 2 implants displayed evidence of progressive AL but had not failed at last follow-up. 5 of 11 tibial component revisions in distal femoral replacement were due to AL. 1 major complication occurred after revision surgery for AL in a primary implant: deep infection requiring 2 stage revision. Bony collar ongrowth was significantly higher in all 4 quadrants (anterior, posterior, medial and lateral) in the well-fixed as opposed to loose group, demonstrating a strong negative relationship in each quadrant between bony ongrowth and AL (p0.001) in the presence of patient growth as shown by increased bone:implant width ratio. In both groups, collar ongrowth was greatest in the posterior quadrant. Summary and Conclusions: AL has been confirmed as a common cause of failure in massive extendable endoprostheses. Revision surgery is difficult and may cause serious complications. For the first time, a significant relationship between a well fixed implant stem and bony ongrowth onto a HA coated collar in the context of massive implants used in tumour surgery has been demonstrated. This newly-proven relationship may result in longer-term implant survival and thus a reduced need for revision surgery. It is hoped that this study will provide the basis for further study of this relationship

Background. Extendable partial femoral replacements (EPFR) permit limb salvage in children with bone tumours in proximity to the physis. Older designs were extended through large incisions or minimally invasive surgery. Modern EPFR are lengthened non-invasively. Lengthening improves functional score (Futani, 2006) but has been associated with complications including infection (Jeys, 2005). This study is the first to look specifically at the relationship between EPFR lengthening and complications. Method. Retrospective review of 51 paediatric (<16 years) oncology patients undergoing primary (1 °) EPFR (minimally/noninvasive) between 06/1994 and 01/2006. Exclusions: 1 patient with 5cm extension without medical intervention and 5 patients with incomplete data. Results. There was a negative relationship between age at 1 ° operation and EPFR lengthening (p = 0.03). Mean lengthening for all (including revision) EPFR was 3cm (range 0–13.05). 28 (64%) patients were lengthened a mean 4.8cm at a mean 7 procedures each. 18 were not lengthened, of which 12 were deceased at last followup and 1 had undergone amputation. Lengthening of secondary prostheses contributed a mean 3.7cm to limb length. 2 tertiary implants were lengthened noninvasively by 1.2cm (3 lengthenings) and 1.275cm (5 lengthenings). 16 of 21 failed 1 ° femoral components had been lengthened. The 21 implants underwent a mean 4.2 lengthenings in comparison to mean 1.3 lengthenings in the 28 that did not fail. Number of 1 ° prosthetic lengthenings was positively related to risk of component failure (p = 0.035) and total number of complications (p = 0.049). Complication rate was also related to total lengthening of 1 ° prosthesis (in cm) (p = 0.004). There was a statistically insignificant (p = 0.059) trend towards increased infection rate with higher number of minimally invasive lengthening procedures. Complications were commoner in those undergoing lengthening (mean 3 vs 1.75 in non-lengthened prostheses). Number of lengthenings correlated with number of complications (p = 0.001). Total lengthening of distal EPFR correlated with incidence of knee fixed flexion deformity (FFD)(p = 0.034). Median lengthening was 3cm in those with FFD and 0cm in those without (p = 0.019). Open lengthening procedures caused 6 complications: 2 deep & 3 superficial infections and recurrent subluxation requiring acetabuloplasty in a proximal replacement. Summary/Conclusions. The inverse relationship between age at 1 ° operation and lengthening is expected if the aim of offsetting limb length discrepancy during growth is being achieved. Lengthening is associated with increased complications (particularly infection and FFD) and femoral component failure, suggesting that lengthening procedures are implicated in the cause of some complications. 5 infective complications after lengthening were theoretically avoidable if noninvasive growers were used
