Objectives. The surgical challenge with severe hindfoot injuries is one of technical feasibility, and whether the limb can be salvaged. There is an additional question of whether these injuries should be managed with limb salvage, or whether patients would achieve a greater quality of life with a transtibial amputation. This study aims to measure functional outcomes in military patients sustaining hindfoot fractures, and identify injury features associated with poor function. Methods. Follow-up was attempted in all United Kingdom military casualties sustaining hindfoot fractures. All respondents underwent short-form (SF)-12 scoring; those retaining their limb also completed the American Academy of Orthopaedic Surgeons Foot and Ankle (AAOS F&A) outcomes questionnaire. A multivariate regression analysis identified injury features associated with poor functional recovery. Results. In 12 years of conflict, 114 patients sustained 134 fractures. Follow-up consisted of 90 fractures (90/134, 67%), at a median of five years (interquartile range (IQR) 52 to 80 months). The median Short-Form 12 physical component score (PCS) of 62 individuals retaining their limb was 45 (IQR 36 to 53), significantly lower than the median of 51 (IQR 46 to 54) in patients who underwent delayed amputation after attempted reconstruction (p = 0.0351). Regression analysis identified three variables associated with a poor F&A score: negative Bohler’s angle on initial radiograph; coexisting talus and calcaneus fracture; and tibial plafond fracture in addition to a hindfoot fracture. The presence of two out of three variables was associated with a significantly lower PCS compared with amputees (medians 29, IQR 27 to 43 vs 51, IQR 46 to 54; p < 0.0001). Conclusions. At five years, patients with reconstructed hindfoot fractures have inferior outcomes to those who have delayed amputation. It is possible to identify injuries which will go on to have particularly poor outcomes. Cite this article: P. M. Bennett, T. Stevenson, I. D. Sargeant, A. Mountain, J. G. Penn-Barwell.

Aim. Repeat revision surgery of total hip or knee replacement may lead to massive bone loss of the femur. If these defects exceed a critical amount a stable fixation of a proximal or distal femur replacement may not be possible. In these extraordinary cases a total femur replacement (TFR) may be used as an option for limb salvage. In this retrospective study we examined complications, revision free survival (RFS), amputation free survival (AFS) and risk factors for decreased RFS and AFS following a TRF in cases of revision arthroplasty with a special focus on periprosthetic joint infection (PJI). Method. We included all implantations of a TFR in revision surgery from 2006–2018. Patients with a primary implantation of a TFR for oncological indications were not included. Complications were classified using the Henderson Classification. Primary endpoints were revision of the TFR or disarticulation of the hip. The minimum follow up was 24 month. RFS and AFS were analyzed using Kaplan-Meier method, patients´ medical history was analyzed for possible risk factors for decreased RFS and AFS. Results. After applying the inclusion criteria 58 cases of a TFR in revision surgery were included with a median follow-up of 48.5 month. The median age at surgery was 68 years and the median amount of prior surgeries was 3. A soft tissue failure (Henderson Type I) appeared in 16 cases (28%) of which 13 (22%) needed revision surgery. A PJI of the TFR (Henderson Type IV) appeared in 32 cases (55%) resulting in 18 (31%) removals of the TFR and implantation of a total femur spacer. Disarticulation of the hip following a therapy resistant PJI was performed in 17 cases (29%). The overall 2-year RFS was 36% (95% confidence interval(CI) 24–48%). Patients with a Body mass Index (BMI) >30kg/m² had a decreased RFS after 24 month (>30kg/m² 11% (95%CI 0–25%) vs. <30kg/m² 50% (95%CI 34–66%)p<0.01). The overall AFS after 5 years was 68% (95%CI 54–83%). A PJI of the TFR and a BMI >30kg/m² was significantly correlated with a lower 5-year AFS (PJI 46% (95%CI 27–66%) vs no PJI 100%p<0.001) (BMI >30kg/m² 30% (95% KI 3–57%) vs. <30km/m² 85% (95% KI 73–98%)p<0.01). Conclusions. A TFR in revision arthroplasty is a valuable option for limb salvage but complications in need of further revision surgery are common. Patients with a BMI >30kg/m² should be informed regarding the increased risk for revision surgery and loss of extremity before operation

Aims. The aim of this study was to investigate the safety and efficacy of 3D-printed modular prostheses in patients who underwent joint-sparing limb salvage surgery (JSLSS) for malignant femoral diaphyseal bone tumours. Methods. We retrospectively reviewed 17 patients (13 males and four females) with femoral diaphyseal tumours who underwent JSLSS in our hospital. Results. In all, 17 patients with locally aggressive bone tumours (Enneking stage IIB) located in the femoral shaft underwent JSLSS and reconstruction with 3D-printed modular prostheses between January 2020 and June 2022. The median surgical time was 153 minutes (interquartile range (IQR) 117 to 248), and the median estimated blood loss was 200ml (IQR 125 to 400). Osteosarcoma was the most common pathological type (n = 12; 70.6%). The mean osteotomy length was 197.53 mm (SD 12.34), and the median follow-up was 25 months (IQR 19 to 38). Two patients experienced local recurrence and three developed distant metastases. Postoperative complications included wound infection in one patient and screw loosening in another, both of which were treated successfully with revision surgery. The median Musculoskeletal Tumor Society score at the final follow-up was 28 (IQR 27 to 28). Conclusion. The 3D-printed modular prosthesis is a reliable and feasible reconstruction option for patients with malignant femoral diaphyseal tumours. It helps to improve the limb salvage rate, restore limb function, and achieve better short-term effectiveness. Cite this article: Bone Jt Open 2024;5(4):317–323

Introduction. Severe, multiplanar, fixed, pantalar deformities present a challenge to orthopaedic surgeons. Surgical options include limb salvage or amputation. This study compares outcomes of patients with such deformities undergoing limb preservation with either pantalar fusion (PTF) or talectomy and tibiocalcaneal fusion (TCF), versus below knee amputation (BKA). Methods. Fifty-one patients undergoing either PTF, TCF and BKA for failed management of severe pantalar deformity were evaluated retrospectively. Twenty-seven patients underwent PTF, 8 TCF and 16 BKA. Median age at surgery was 55.0 years (17 to 72 years) and median follow-up duration was 49.9 months (18.0 to 253.7 months). Patients with chronic regional pain syndrome, tumour, acute trauma or diabetic Charcot arthropathy were excluded. Clinical evaluation was undertaken using the MOxFQ, EQ-5D and Special Interest Group in Amputee Medicine score (SIGAM). Patients were also asked whether they were satisfied with their surgical outcome and whether they would have the same surgery again. Results. There was no statistically significant difference in patient reported outcomes, satisfaction, or complication profile between the groups. Twenty-two patients undergoing PTF (81.5%), 6 patients undergoing TCF (75%), and 15 patients undergoing BKA (93.8%) were satisfied overall (p=0.414). Similarly, there was no difference in the proportion of patients who would opt for the same procedure again (p=0.142): 23 in the PTF group (85.2%), 8 in the TCF group (100%), and 11 in the BKA group (68.8%). Seven patients undergoing PTF (25.9%), 2 patients undergoing TCF (25%) and 6 patients undergoing BKA (37.5%) had major complications (p=0.692). Conclusion. This study has shown that PTF, TCF and BKA can all provide an acceptable outcome in treatment of severe, degenerative deformities of the lower extremity. Therefore, surgical decisions must be based on individual patient considerations. This data may also be useful in counselling patients when considering limb salvage versus amputation for severe deformity

Abstract. Background. Reconstruction following resection of sarcomas of the upper extremity with methods described in the prevalent literature may not be possible in few selected cases. We describe Surgical Phocomelia or Phoco-reduction as a method of limb salvage in such cases of extensive sarcomas of the upper limb with its functional and oncological outcomes. Methods. Evaluation of functional and oncological outcomes was performed for 11 patients who underwent surgical phocomelia or phocoreduction for extensive sarcomas of the upper limb between 2010 and 2019. Results. Mean follow-up period in the study was27.8 months. Five patients required a segmental resection including the entire humerus while 6 patients underwent segmental resection around the elbow with a mean resection length of 21.5 cm. Mean MSTS 93 score was 22 depicting a good functional outcome. Mean hand grip strength on the operated side was 62% of the contralateral side with preservation of useful hand function. Mean time to humero-ulnar union was 6.7 months. Radial nerve palsy and implant failure occurred in 1 patient each. No patient developed local recurrence while 3 patients died of metastasis. Conclusion. Surgical phocomelia is a prudent alternative to severely incapacitating amputations in situations where other reconstruction methods are not feasible

Amputation was once widely practised for primary bone tumours of the limbs. Yet this situation has changed with limb salvage surgery becoming increasingly popular in the last 30 years. Many different techniques are now available. These include allografts, autografts, endoprostheses and allograft-prosthesis composites. This article reviews these methods, concentrating on the functional outcomes and complications that have been reported

Prior to the 1970s, almost all bone sarcomas were treated by amputation. The first distal femoral resection and reconstruction was performed in 1973 by Dr Kenneth C Francis at the Memorial Sloan-Kettering Cancer Centre in New York. Since that time, limb-sparing surgery for primary sarcoma has become the mainstay of sarcoma surgery throughout the world. Initially, the use of mega-prostheses of increasing complexity, involving all the major long bones and both pelvic and shoulder girdles, was popularised. In the early 1980s, wide use of massive allograft reconstructions became widespread in both Europe and in multiple centres in the USA and UK. Since that time, increasing complexity in the design of prostheses has allowed for increasing functional reconstructions to occur, but the use of allograft has become less popular due to the development of late graft failures of patients survive past ten years. Fracture rates approaching 50% at 10 years are reported, and thus, other forms of reconstruction are being sought. Techniques of leg lengthening, and bone docking procedures to replace segmental bone loss to tumour are now employed, but the use of biological vascularised reconstructions are becoming more common as patient survivorship increases with children surviving their disease. The use of vascularised fibular graft, composite grafts and re-implantation of extra-corporeally irradiated bone segments are becoming more popular. The improvement in survivorship brought about the use of chemotherapy is producing a population of patients with at least a 65% ten year survivorship, and as many of these patients are children, limb salvage procedures have to survive for many decades. The use of growing prostheses for children have been available for some 25 years, first commencing in Stanmore, UK, with mechanical lengthening prostheses. Non-invasive electro-magnetic induction coil mechanisms are now available to produce leg lengthening, with out the need for open surgery. Whilst many of these techniques have great success, the area of soft tissue attachment to metallic prostheses has not been solved, and reattachment of muscles is of great importance, of course, for return of function. There are great problems in the shoulder joints where sacrifice of rotator cuff muscles is necessary in obtaining adequate disease clearance at the time of primary resection, and a stable shoulder construct, with good movement, has yet to emerge. Similar areas of great difficultly remain the peri-acetabular and sacro-iliac resections in the pelvis. Perhaps the real future of the art of limb salvage will be in the reconstruction of failed major joint replacements where there is great loss of bone stock, and already massive tumour prostheses are providing a salvage pathway for failed standard joint replacement. The final future for limb salvage, however, may not rest with increasing surgical complexity and innovation, but with the development of molecular biology and specific targeted treatments, according to the cytogenetics of a particular tumour. We are on the threshold of yet another quantum change in the approach to cancer management; just as chemotherapy brought a tremendous change in the 1970s, molecular biology is the frontier to make much of the current limb salvage surgery that is performed redundant

To compare the costs of treatment and income received for treating patients with tibial osteomyelitis, comparing limb salvage with amputation. We derived direct hospital costs of care for ten consecutive patients treated with limb salvage procedures and five consecutive patients who underwent amputation, for tibial osteomyelitis. We recorded all factors which affect the cost of treatment. Financial data from the Patient-Level Information and Costing System (PLICS) allowed calculation of hospital costs and income received from payment under the UK National Tariff. Hospital payment is based on primary diagnosis, operation code, length of stay, patient co-morbidities and supplements for custom implants or external fixators. Our primary outcome measure was net income/loss for each in-patient episode. The mean age of patients undergoing limb salvage was 55 years (range 34–83 years) whereas for amputation this was 61 years (range 51–83 years). Both groups were similar in Cierny and Mader Staging, requirement for soft-tissue reconstruction, anaesthetic technique, diagnostics, drug administration and antibiotic therapy. In the limb salvage group, there were two infected non-unions requiring Ilizarov method and five free flaps. Mean hospital stay was 15 days (10–27). Mean direct cost of care was €16,718 and mean income was €9,105, resulting in an average net loss of €7,613 per patient. Patients undergoing segmental resection with Ilizarov bifocal reconstruction and those with the longest length of stay generated the greatest net loss. In the amputation group, there were 3 above knee and 2 below knee amputations for failed previous treatment of osteomyelitis or infected non-union. Mean hospital stay was 13 days (8–17). Mean direct cost of care was €18,441 and mean income was €15,707, resulting in an average net loss of €2,734 per patient. Length of stay was directly proportional to net loss. The UK National Tariff structure does not provide sufficient funding for treatment of osteomyelitis of the tibia by either reconstruction or amputation. Average income for a patient admitted for limb salvage is €6,602 less than that for amputation even though the surgery is frequently more technically demanding (often requiring complex bone reconstruction and free tissue transfer) and the length of hospital stay is longer. Although both are significantly loss-making, the net loss for limb salvage is more than double that for amputation. This makes treatment of tibial osteomyelitis in the UK National Health Service unsustainable in the long term

Wide resection of bone tumour has become an accepted treatment in the limb salvage surgery. The reconstruction of the residual defect following wide resection is a major problem. Author had reviewed the results of five reconstruction methods. Osteoarticular graft is suitable for proximal tibial reconstruction and endoprosthesis for distal femoral reconstruction. Autograft is rarely used to reconstruct the large residual defect. Cement can reconstruct the larger defect, but it is not a suitable procedure on long term basis. Health technology has been defined by WHO as the set of techniques, drugs, equipment and procedure used by health care professionals in delivering medical care to individuals and the system within which such care is delivered. Health technology assessment includes analyses of safety, efficacy and effectiveness, cost and cost effectiveness, infrastructure factors, social impact and fit, needs and capabilities of local health care delivery system. The reimplanatation of resected autoclaved tumour bone graft is technically a simple, financially a cost saving and a biological solution for this difficult problem. This method of reconstruction fulfills all criteria of health technology. It is the suitable method of reconstruction in limb salvage surgery for all countries, but most suitable for the developing and poor countries where the resources for other methods are not available due to financial, technical or socio-cultural reasons

Nowadays 80% of patients with bone sarcomas can benefit from limb salvage. Their disease-free life expectancy is not jeopardised by conservative surgery as long as safe margins are obtained. For this reason, the oncological result relies on the accuracy of pre-operative and per-operative surgical measurements. Pre-operative evaluation of tumours is now quite accurate with digital margins (computed tomography, MNR, digital angiography). However, surgeons are still using centimeters or conventional radiographs with their own technical limitations for per-operative evaluation. A more accurate technique is needed. The system is composed of three components: 1) a color, graphic computer workstation with software to calculate and present the location of the surgical instrument on a three-dimensional, reconstructed bone image, 2) a complete set of hand-held instruments containing infrared emitters, 3) an infrared receiver linked to the work station. This measuring system enables determination of the position and incidence of a surgical instrument in real time during surgery, with an accuracy of less than one mm. The system requires four steps: 1) recording data with C.T., N.M.R. or angiography, 2) creating a three-dimensional image displayed on the computer screen for preoperative simulation of a virtual operation, 3) recording the very important anatomical points of the patient and optimal incidences of the surgical instruments, 4) preoperative location of surgical instruments and control of their location on bone. This system is very useful for resection of bone tumours when the conventional location is uncertain (innonimate bone, rib), when very sharp accuracy is needed to preserve the growth plate of the distal femur in young children, and to avoid medullary damage in a spinal tumour. The frameless stereotactic device is also very accurate in the reconstructive phase of limb salvage. After an internal hemipelvectomy, the device permits localisation of the acetabular prosthesis in the precise location before resection. In our practice, the accuracy of the video guiding system is always within two mm as compared to conventional measurements usually between one or two cm for long bones and three to five cm for innominate bone. The use of a video guidance system is very beneficial for limb salvage surgery for pelvic bone tumours

Introduction: Malignant tumours of the foot and ankle are rare. The aim of the study was to document one of the largest series of malignant tumours affecting the foot and ankle and to assess the outcomes following limb salvage and amputation. Methods: The study was a retrospective review of the patients with a malignant tumour of the foot and ankle. Demographic details, diagnosis, treatment and outcomes were retrieved from the electronic patient records containing information on over 20 000 patients seen over a 25 year period. Results: Two hundred and twenty five patients had malignant tumours affecting the foot and ankle. It was common in the fifth decade (35 patients). The mean age was 46 years. The commonest diagnosis was synovial sarcoma (40 patients) followed by chondrosarcoma (23 patients) and Ewing’s sarcoma (21 patients). The mean tumour size was 5.6 cm (0.8 to 17.5 cm). 82 patients (37%) underwent an unplanned excision and 13% (29 patients) presented with metastases at diagnosis. Primary bone tumours were 28% (64 patients), soft tissue sarcomas were 62% and metastatic tumours were 8% while lymphoreticular malignancies were (1%). Limb salvage was possible in 71% (156 patients). 29% (65 patients) had a below knee amputation. 7% (15 patients) had a local recurrence. The 5 years survival was 63%. The 5 years survival for the patients who had limb salvage was 68% compared with 54% for the patients who had an amputation (p 0.03). Conclusion: Though amputation can provide better local control, limb salvage surgery improves survival

Purpose: To review the oncologic outcomes following treatment of soft tissue sarcomas in the foot and ankle, and to determine the results of limb salvage surgery in this anatomically constrained area with often expected close pathologic margins. Method: One hundred twenty-nine patients with soft tissue sarcomas of the foot were treated at our institution since 1986. Average age at presentations was 55 years old. Females and males were equally represented. Most common diagnosis was MFH in 31 patients, followed by leiomyosarcoma in 16 patients, synovial sarcoma in 13, and clear cell sarcoma in 6, the remainder being other soft tissue sarcomas. Most of sarcomas were intermediate or high grade. Our follow-up averaged 58 months. Results: Limb salvage surgery was possible in 97 patients. Of those, negative margin excision was achieved in 75 patients, 18 patients had micro-positive margins, and 4 had grossly positive margins. Fifty-three patients in the limb salvage group required free tissue transfer for coverage. Of 97 limb salvage patients, 82 received radiation therapy, 5 patients received chemotherapy. Local recurrence occurred in 24 patients. Two of these were amenable to re-excision, the remaining required amputation. Thirty-two patents developed systemic disease. Average disease-free survival for patients with recurrent disease was 23 months. At last follow-up, 78 patients were alive with no evidence of disease and 24 were alive with disease. Seventeen patients died of disease, and the remainder of other causes. Conclusion: In the setting of soft tissue sarcoma in foot and ankle, amputation rate is higher than in other anatomic areas. However, limb salvage surgery can be achieved with good oncological outcomes despite often unavoidable close margins. Soft tissue reconstructive procedures aid in achieving good surgical results while radiation therapy aids local control. Given these results, limb salvage in soft tissue tumors of foot and ankle should be the goal

Neoadjuvant chemotherapy for osteosarcoma improves outcomes for the majority, but if the chemotherapy does not work then the dilemma often arises as to whether to do limb salvage with a marginal (or worse) margin of excision or to do an amputation. If limb salvage is carried out with a close margin, does post operative radiotherapy make any difference? This study aims to address these questions. Method. All patients with limb osteosarcoma, no metastases, a poor response to chemotherapy and either a marginal excision or primary amputation were identified from a prospective database. This group were investigated in terms of overall survival and local control. Results. There were 182 patients in this category of whom 60 had an amputation, 105 limb salvage with marginal margins and 17 with an intralesional margin. Local recurrence (LR) arose in 41% of those with an intralesional margin, 22% of those with a marginal margin and 13% of those with an amputation. Radiotherapy was used in 21 of the 122 patients and the risk of LR was the same as in those who did not have radiotherapy. Neither age nor sex of the patient, size or site of the tumour affected the risk of LR. The overall survival for this group was 42% at 10 years. The survival was best in those with marginal margins (38%) than those with an amputation (28%) and worst for those with an intralesional margin (20%). Survival was worst in those who did develop LR, but no worse than in those having amputation. Conclusion. A marginal resection of osteosarcoma with a poor response to chemotherapy leads to a high risk of local recurrence but also carries a poor prognosis. Carrying out an amputation to avoid the risk of LR probably has little survival benefit and the use of radiotherapy remains unclear

The purpose of the study was to evaluate the functional outcome of different limb salvage procedures for osteosarcoma about the knee. A selection of patients who have undergone limb salvage procedures for osteosarcoma about the knee were invited to join the study. Medical and operation notes were reviewed along with recent radiographs of the involved limb. Patients completed the Musculoskeletal Tumour Society functional questionnaire and underwent a gait analysis assessing walking and running. Most patients had stage 2B osteosarcoma involving either the proximal tibia or distal femur. Limb salvage procedures included arthrodesis, allograft reconstruction, endoprosthesis and rotationplasty. All patients scored highly (> 70 %) on the MSTS questionnaire except the arthrodesis that scored 57 %. The gait analysis revealed some subtle changes with a quadriceps-sparing gait in the endoprosthesis, mild foot drop in the proximal tibial allograft and a lateral lean of the trunk over the ipsilateral limb in the rotationplasty. The arthrodesis had an obvious straight leg gait with subtle pelvic hiking to assist foot clearance. While analysis of walking was close to normal most patients were unable to obtain a double float and run. This study shows that limb salvage procedures tailored to each individual case can result in an excellent functional outcome with close to normal gait and high MSTS scores

Endoprosthetic reconstruction as a form of limb salvage in the management of malignant disease is common. We present our experience with custom-made distal femoral replacement as a form of limb salvage in the absence of malignancy. 49 cases of distal femoral replacement were identified using the unit database. There were 18 males and 31 females, with a mean age at operation of 62.3 years (range 26–86). There were 29 cases of failed total knee replacements, 8 cases of fracture associated with bone loss, non-union or deformity, 7 periprosthetic fractures, 3 aneurysmal bone cysts, and one case each of avascular necrosis and Gorham’s disease. Clinical and radiographic review of all available patients, including a functional assessment with the Musculoskeletal Tumour Society (MSTS) Score and Toronto Extremity Salvage (TES) score was undertaken. The average follow-up was 5.4 years (range 1 to 29 years). Three types of endoprosthesis were used, rotating hinge, fixed hinge and arthrodesis prosthesis. One patient required amputation at 2 months following post-operative wound infection with methicillin-resistant staphylococcus aureus and subsequent inability to provide adequate soft tissue coverage. There was one revision at 16 months for deep prosthetic infection. 21 patients were available for functional follow-up. The mean MSTS score was 63.7 (range 16.0–86.7) and the mean TES score was 59.4 (range 9.4–87.5). Custom-made distal femoral replacements have an established role in limb-salvage surgery for malignant disease. This series demonstrates the reconstructive capability of custom prostheses in non-malignant disease, where deformity causes functional embarrassment or when massive bone loss would normally lead to amputation

Aim: To assess the functional outcomes for patients treated by limb salvage surgery for sarcomas of the upper limb and shoulder girdle. Materials and methods: Patients who had undergone limb salvage surgery for upper limb sarcoma between 1997 and 2004 were entered into the study. The operation notes were used to obtain details of the surgery. Pathology reports were consulted to identify the type, grade and margins of the tumour. The Toronto Extremity Salvage Score (TESS) questionnaire was used to assess post-operative function, in a postal survey. Results: A total of 62 patients were identified. Liposarcoma was most common histological diagnosis, and “low” the most common grade (27). Histologically clear margins were achieved in 28 (44%) cases, marginal in 2 (3%), incomplete in 13 (21%) and indeterminate in 20 (32%). 30% had received adjuvant radiotherapy with or without chemotherapy as indicated. A total of 48 (76%) had been treated with excision and primary closure, 7 (11%) with local flaps, and 4 (6%) with endoprostheses. 10 patients had died, and 1 was untraceable. 29 completed TESS questionnaires were returned; with an average follow-up of 33 months post-resection (range 4 to 83). 11 female (38%), 18 male (62%), with an average age at surgery of 55. The average TESS score was 77 +/−10 with a range of 18–100. For the different regions, forearm sarcomas had an average TESS of 81 +/−17, upper arm 76 +/−19 and shoulder 81 +/−14. Discussion: Surgical excision of soft tissue tumours with limb salvage aims to balance morbidity and mortality. Upper limb amputation has greater morbidity than lower limb and thus the argument for limb salvage should be stronger. A limb-salvage procedure should be considered preferable to amputation provided oncological outcomes are not compromised, and the resulting functional outcome is worth the oncological risk. In this cohort, patients had good functional outcomes, as described by the TESS functional assessment score, with no evidence of compromised oncological outcome during the follow up period

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

To assess the performance and success of joint sparing limb salvage surgery in high grade malignancy, in terms of function, complications, recurrence and survival, as compared to joint resection. We report a ten-year experience of twenty patients with high grade malignancies of bone which did not cross the epiphyseal plate. They underwent not only limb salvage surgery but also joint preservation. The aim of this is to preserve function in the joint and to prevent the inevitable wear of prosthetic joints requiring revision surgery. The age range was 4 - 25 years (mean 13. 5). The Diagnoses were 14 Osteosarcomas and 6 Ewings sarcomas. Mean follow up was 49 months. There were 13 femoral & 7 tibial malignancies. 12 underwent complex biological fixation with a combination of reimplanted autoclaved or irradiated bone; vascularised fibular graft; femoral or humeral allograft. In 8 cases custom made hydroxyapatite coated prostheses were used to replace the resected bone. This surgery must clearly be evaluated in the context of recurrence, particularly as this is associated with an increased risk of metastases and death. Analysis of our results to date has not shown a greater rate of complications. We experienced one recurrence, and one death. The custom prostheses group had fewer complications and operations. Functionally these patients report near normal limbs and joints and do not report any limitation of activities. Joint sparing limb salvage surgery is extremely worthwhile as it produces a significantly better functioning limb and lower morbidity, with less likelihood of revision surgery. We have not found a higher risk of post-operative complications, recurrence or death. Furthermore massive prosthetic replacement is quicker, osseointegrates reliably and is associated with a lower complication and further operation rate

Introduction: Primary bone lymphoma is a rare neoplastic disease of bone. Treatment consists predominantly of chemotherapy and radiotherapy. Surgery can be considered for large lytic lesions with impending pathological fractures. This study was performed to find the functional and oncological outcome of patients who underwent limb salvage surgery and custom mega prosthesis for lymphoma of bone. Materials and Methods: Eight patients with lymphoma of bone underwent limb salvage surgery and reconstruction with custom made prosthesis. Males predominated in the study with the average age of 30 years. Lower limb was commonly involved: 6 patients had tumour involving the femur. Five patients had pathological fracture. Resection and reconstruction was done using custom mega prosthesis. Proximal humeral prosthesis was used for proximal humeral tumour and proximal femoral or total hip prosthesis for proximal femoral lesion. One patient each had total femoral prosthesis and total knee prosthesis. Results: With an average follow-up of 78.6 months, two patients died of disease and one patient was alive with disease. The patient with femoral shaft lesion had intra-operative vascular injury requiring vascular repair. The patient with total knee prosthesis had superficial skin necrosis which required skin cover. The functional outcome was satisfactory in 5 patients. Discussion: Primary bone lymphoma accounts for 7% of all bone tumours. There is a male predominance and femur is the most common site of involvement. Five patients in our series had pathological fractures warranting surgical stabilisation. Limb salvage surgery with custom mega prosthesis appears to be a feasible option as more than 65% of our patients had satisfactory functional outcome. They were able to mobilise early with good pain relief and a useful functional limb
