Introduction. We present a case of a 49-year-old patient who initially presented in May 2020 with an open pilon fracture. Managed with initial debridement, fixation and flap - who subsequently underwent circular frame application for failure of fixation, requiring a transport to fusion frame who developed beta-haemolytic streptococcus A within the site of the proximal corticotomy. Materials & Methods. A systematic review of the literature was conducted searching EMBASE, MEDLINE and Cochrane library for all articles discussing infected bone regenerate- a paucity of information was found. Abstracts were independently reviewed by 2 authors (LH and LT). In total, there were 16 papers, and then subsequently analysed we identified two case reports regarding infected regenerate. Results. Developing an infection in a regenerate is highly rare with very few reported cases within the published literature. The literature identified risk factors for an infected regenerate, with open fracture and smoking being the two consistent factors. The open fracture deep infection rate is cited at 10% in most publications, this is at the site of the open fracture and not within the regenerate. Conclusions. Infection within the regenerate during distraction osteogenesis is highly unusual, with only two other published papers in the literature to the best of our knowledge. This should be borne in mind when managing patients with infection of unknown sources in cases of distraction osteogenesis

Introduction. Hip dysplasia is the most common congenital deformity of the musculoskeletal system. This is a pathology that brings the hip joint from subluxation to dislocation. Frequency of hip dysplasia − 16 children per 1000 newborns. Materials and Methods. Diagnostic methods of research are X-ray inspection which is necessarily carried out at internal rotation (rotation) of an extremity as lateral rotation of a hip on the radiograph always increases an angle of a valgus deviation of a neck. Surgical treatment is performed in the subclavian area of the femur. An external fixation device is applied and a corrective corticotomy is performed, and valgus deformity and anteversion are eliminated. The duration of treatment is 2.5–3 months. Results. Frequency of hip dysplasia − 16 children per 1000 newborns. We perform about 30 operations a year, including 60% girls and 40% boys. In addition, valgus deformity can be traced -. - in cerebral palsy. - after polio. - at progressing muscular dystrophies. - tumor in the area of the epiphyseal cartilage. At insufficient stability in a hip joint at insufficiently expressed roof of an acetabulum of rotational deformation of a neck of a hip, for prevention of a coxarthrosis and normalization of a ratio of articular ends operation detorsion-varying subvertebral corticotomy of a femur is shown. Conclusions. The operation is minimally invasive, with accesses of 5–6 mm, anatomical and topographical features are taken into account, which will eliminate damage to tissues, nerve trunks and the circulatory system

Introduction. Critical limb ischemia (CLI) is the reduced blood flow in the arteries of the lower extremities. It is a serious form of peripheral arterial disease, or PAD. If left untreated the complications of CLI will result in amputation of affected limb. The treatment experience of diabetic foot with transverse tibial transport was carried out by Ilizarov technique. Madura foot ulcer is not a common condition. It disturbs the daily activities of the patient. Pain swelling with multiple nodules with discharging sinus with discoloration(blackening) of the affected area is the main problem. Materials and Methods. We treated total case: 36 from Jan. 2003 – Jan. 2020 (17yrs.). Among these-. TAO- 20. Limb Ishchemia- 5. Diabetic Foot- 9. Mycetoma pedis- 2. Infected sole and dorsum of the foot- 5. Results. Transverse corticotomy and wire technique followed by distraction increases blood circulation of the lower limbs, relieving the pain. The cases reported here were posted for amputation by the vascular surgeons, who did not have any other option for treatment. Hence we, re-affirm that Academician Prof. Ilizarov's method of treatment does help some patients suffering from these diseases. Conclusions. By Ilizarov compression distraction device for TAO, modura foot ulcer, diabetic foot ulcer, mycetoma pedis ulcer, infected sole and dorsum of the foot ulcer were treated by introducing K/wires through the bones with proper vertical corticotomy. Application of this noble device will bring angeogenesis within the reach of all deserving patients

Aim. Post traumatic distal tibia osteomyelitis (DTOM) with an upper ankle joint involvement is a serious complication after primary osteosynthesis and can be a nightmare for the patient and the surgeon as well. Our aim was to identify mayor complications during treatment and to find the way to prevent or treat them. Method. It is a retrospective analysis of eight patients with DTOM and an upper ankle joint involvement treated in our institution from 2012 to 2018. The average size of a bone defect after a debridement was 9 centimeters (4–15). Patients were treated in two stages. First stage was segmental bone resection, external fixation and soft tissue envelope reconstruction if necessary. At second stage a distraction frame was applied and proximal corticotomy performed. In all but one case a circular frame was used. Results. We have had one major intra-operative complication, an injury of arteria tibialis posterior during the corticotomy procedure. Except in one patient we did not observe major problems with pin-track infections. Despite bone-grafting in all patients, we observed three nonunions of docking site. We treated them by external fixator in two and retrograde intramedullar nail in one case. In two patient the distraction callus was weak. We had to bone graft and secure the callus with a plate in one and use a retrograde reamed intramedullar nail in second patient. We have observed two callus fracture after removal of the frame. A surgery was needed for both because of the deformation. The first patient was treated by new external frame, the second by retrograde reamed intramedullar nail. Conclusions. Callus distraction is a valuable option to treat a bone defect. The procedure has many possible problems and complications, especially during treatment of defects larger than six centimeters. It is very difficult for patients to tolerate a frame more than one year. We have found the use of an intramedullar tibial nail inserted in a retrograde way as a helpful option not just to shorten the time of external frame, but in combination with reaming also to accelerate the healing of the distraction callus and the upper ankle joint arthrodesis as well

Introduction. Bone transport and distraction osteogenesis have been shown to be an effective treatment for significant bone loss in the tibia. However, traditional methods of transport are often associated with high patient morbidity due to the pain and scarring caused by the external frame components transporting the bone segment. Prolonged time in frame is also common as large sections of regenerate need significant time to consolidate before the external fixator can be removed. Cable transport has had a resurgence with the description of the balanced cable transport system. However, this introduced increasingly complex surgery along with the risk of cable weave fracture. This method also requires frame removal and intramedullary nailing, with a modified nail, to be performed in a single sitting, which raised concern regarding potential deep infection. An alternative to this method is our modified cable transport system with early intramedullary nail fixation. Internal cables reduce pain and scarring of the skin during transport and allow for well controlled transport segment alignment. The cable system is facilitated through an endosteal plate that reduces complications and removes the need for a single-stage frame removal and nailing procedure. Instead, the patients can undergo a pin-site holiday before nailing is performed using a standard tibial nail. Early intramedullary nailing once transport is complete reduces overall time in frame and allows full weight bearing as the regenerate consolidates. We present our case series of patients treated with this modified cable transport technique. Methodolgy. Patients were identified through our limb reconstruction database and clinic notes, operative records and radiographs were reviewed. Since 2019, 8 patients (5 male : 3 female) have undergone bone transport via our modified balanced cable transport technique. Average age at time of transport was 39.6 years (range 21–58 years) with all surgeries performed by the senior author. Patients were followed up until radiological union. We recorded the length of bone transport achieved as well as any problems, obstacles or complications encountered during treatment. We evaluated outcomes of full weight bearing and return to function as well as radiological union. Results. 4/8 bone defects were due to severely comminuted open fractures requiring extensive debridement. All other cases had previously undergone fixation of tibial fractures which had failed due to infection, soft tissue defects or mal-reduction. The mean tibial defect treated with bone transport was 41mm (range 37–78mm). From the start of cable transport to removal of external fixator our patients spent an average of 201 days in frame. 7/8 patients underwent a 2-week pin-site holiday and subsequent insertion of intramedullary nail 2 weeks later. One patient had sufficient bony union to not require further internal fixation after frame removal. 10 problems were identified during treatment. These included 4 superficial infections treated with antibiotics alone and 5 issues with hardware, which could be resolved in the outpatient clinic. 1 patient had their rate of transport slowed due to poor skin quality over the site of the regenerate. 4 obstacles resulted in a return to theatre for additional procedures. 1 patient had a re-do corticotomy and 3 had revision of their internal cable transport constructs due to decoupling or screw pull out. 1 patient had residual ankle joint equinus following treatment which required an Achilles tendon lengthening procedure. Another patient underwent treatment for DVT. There were no deep infections identified and no significant limb length discrepancies or deformities. Conclusions. Overall, we have found that our modified balanced cable transport technique has allowed for successful bone transport for significant defects of the tibia. We have learned from the obstacles encountered during this case series to avoid unnecessary return trips to theatre for our future transport patients. The internal cable system allowed all patients to complete their planned transport without excessive pin tract scarring or pain. Early conversion to intramedullary nail allowed for a shorter time in frame with continued full weight bearing as the regenerate consolidated. No metalwork failure or deformity has occurred in relation to docking site union. All patients have made a good return to pre-operative function during their follow-up period with no evidence of late complications such as deep infection

Aims. The aims of this study were to establish whether composite fixation (rail-plate) decreases fixator time and related problems in the management of patients with infected nonunion of tibia with a segmental defect, without compromising the anatomical and functional outcomes achieved using the classical Ilizarov technique. We also wished to study the acceptability of this technique using patient-based objective criteria. Patients and Methods. Between January 2012 and January 2015, 14 consecutive patients were treated for an infected nonunion of the tibia with a gap and were included in the study. During stage one, a radical debridement of bone and soft tissue was undertaken with the introduction of an antibiotic-loaded cement spacer. At the second stage, the tibia was stabilized using a long lateral locked plate and a six-pin monorail fixator on its anteromedial surface. A corticotomy was performed at the appropriate level. During the third stage, i.e. at the end of the distraction phase, the transported fragment was aligned and fixed to the plate with two to four screws. An iliac crest autograft was added to the docking site and the fixator was removed. Functional outcome was assessed using the Association for the Study and Application of Methods of Ilizarov (ASAMI) criteria. Patient-reported outcomes were assessed using the Musculoskeletal Tumor Society (MSTS) score. Results. The mean age of patients was 38.1 years (. sd. 12.7). There were 13 men and one woman. The mean size of the defect was 6.4 cm (. sd. 1.3). the mean follow-up was 33.2 months (24 to 50). The mean external fixator index was 21.2 days/cm (. sd. 1.5). The complication rate was 0.5 (7/14) per patient. According to the classification of Paley, there were five problems and two obstacles but no true complications. The ASAMI bone score was excellent in all patients. The functional ASAMI scores were excellent in eight and good in six patients. The mean MSTS composite score was 83.9% (. sd. 7.1), with an MSTS emotional acceptance score of 4.9 (. sd. 0.5; maximum possible 5). Conclusion. Composite fixation (rail-plate) decreases fixator time and the associated complications, in the treatment of patients of infected nonunion tibia with a segmental defect. It also provides good anatomical and functional results with high emotional acceptance. Cite this article: Bone Joint J 2018;100-B:1094–9

Aims. The aim of this double-blind prospective randomised controlled trial was to assess whether low intensity pulsed ultrasound (LIPUS) accelerated or enhanced the rate of bone healing in adult patients undergoing distraction osteogenesis. Patients and Methods. A total of 62 adult patients undergoing limb lengthening or bone transport by distraction osteogenesis were randomised to treatment with either an active (n = 32) or a placebo (n = 30) ultrasound device. A standardised corticotomy was performed in the proximal tibial metaphysis and a circular Ilizarov frame was used in all patients. The rate of distraction was also standardised. The primary outcome measure was the time to removal of the frame after adjusting for the length of distraction in days/cm for both the per protocol (PP) and the intention-to-treat (ITT) groups. The assessor was blinded to the form of treatment. A secondary outcome was to identify covariates affecting the time to removal of the frame. Results. There was no difference in the time to removal of the frame between the PP (difference in favour of the control group was 10.1 days/cm, 95% confidence interval (CI) -3.2 to 23.4, p = 0.054) or ITT (difference 5.0 days/cm, 95% CI -8.2 to 18.21, p = 0.226) groups. The smoking status was the only covariate which increased the time to removal of the frame (hazard ratio 0.47, 95% CI 0.22 to 0.97, p = 0.042). Conclusion. LIPUS does not influence the rate of bone healing in patients who undergo distraction osteogenesis. Smoking may influence bone healing. . Cite this article: Bone Joint J 2017;99-B:494–502

Introduction. The BOAST (British Orthopaedic Association Standards for Trauma) guidelines do advise that open pilon fractures amongst other open lower limb fractures need to be treated at a specialist centre with Orthoplastic care. The purpose of this study was to determine clinical outcomes in patients with open pilon fractures treated as per BOAST guidelines including relatively aggressive bone debridement. Methods. A retrospective analysis of a single surgeon series of open pilon fractures treated between 2014 and 2019 was conducted. Injuries were graded according to the Gustillo-Anderson classification and all patients were included for the assessment of the rate of infection and fracture healing. Functional outcome assessment was performed in all patients according to the American Orthopedic Foot and Ankle Score (AOFAS) at 6 months after definitive surgery. Initial wound with bone debridement and application of a spanning external fixator was performed within an average of 13.5 (Range: 3–24) hours. Fixation with FWF (Fine Wire Frame) was performed when the wound was healed, with the mean time from primary surgery to application of FWF being 24.5 (Range: 7–60) days. Results. There was a total of 20 patients including 16 males and 4 females. The mean age was 50.45 (Range: 16–88) years. Follow-up was for an average of 23.2 (Range: 5–51) months. There were 3 patients with Gustilo Type I injuries, 6 with Type II, 4 Type with type IIIa and 7 with Type IIIb injuries. Average time to bone union was 9.3 (Range: 2–18) months. The mean AOFAS score was 66 (Range: 15–97) points. TSF was used on 18 patients, while 2 patients had an Ilizarov frame. A corticotomy was performed on 4 patients with critical bone defect post debridement, while 2 patients had Stimulan beads with antibiotics. There was 1 case (5%) of deep infection and 9 cases (45%) of superficial infection. There were also 2 cases (10%) of non-union which required bone grafting from their femur using a RIA (Reamer Irrigation Aspirator). Other complications included 1 case of acute compartment syndrome, 1 case of pulmonary embolism, 1 case of necrotic skin and 1 case of amputation. Conclusion. Results of our study suggests that the use of staged wound debridement including relatively aggressive bone debridement in conjunction with antibiotics, external fixators and patient tailored conversion from spanning external fixator to fine wire frame achieves low rates of wound infection and complications for patients with open pilon fractures

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. 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. Results:. 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. Discussion:. Both Gigli saw and DeBastiani corticotomy techniques result in good bone formation following distraction osteogenesis. The anterior tibial cortex consolidates more slowly than the other cortices in both groups. This is likely due to deficient soft tissue cover and direct periosteal damage at time of osteotomy

In this paper the results of correction of bone deformities using the llizarov methods, are presented. Fifty-nine patients, 42 with malunion and 17 with mal-nonunion of tibia or femur were operated upon using the llizarov circular fixator. Another 28 cases were corrected using a unilateral device. There were: a) 30 angular deformities, 18 of which were combined with shortening, b) 21 angular deformities associated with translation and c) 36 complex, deformities including angulation, translation, shortening and malrotation. Two rings above and two below the apex of the deformity were always required. Different types of hinges were used between them, depending on the type of the deformity. The corticotomy was performed at the apex of the deformity for the majority of the cases. In 18 patients with hypovascular and eburnated bone, or bone covered with soft tissue of poor quality, the corticotomy was done more proximal or more distal to the apex of the deformity. In complex deformities the correction sequence was: 1) correction of angulation and shortening simultaneously, 2) correction of rotation, 3) and finally correction of translation. The true plane of the deformity and the plane of placement of the hinges were determined by a computerized formula that we developed. The deformities were corrected in all cases in which the hinges were placed at the correct position but in 5 cases we had to re-orient the hinges in order to achieve the correction. The corticotomy or pseudarthrosis consolidated in all cases. Residual leg length discrepancy remained in three patients, not exceeding 135 cm. Great care was taken to prevent complications during operation as well as during the post operative period. However, there were numerous obstacles, problems and true complications. All these were managed aggressively as soon as they appeared. The final results were very satisfactory. We conclude that the revolutionary llizarov methods can solve bone deformity problems that cannot be faced by the traditional methods. It is critically important to place the hinges at the correct position in order to achieve the desired correction. Our computer program definitely helps to this purpose. The surgeon must always be vigilant in order to prevent complications and to deal with them immediately

This study compares the initial outcomes of minimally invasive techniques for single-event multi-level surgery with conventional single-event multi-level surgery. The minimally invasive techniques included derotation osteotomies using closed corticotomy and fixation with titanium elastic nails and percutaneous lengthening of muscles where possible. A prospective cohort study of two matched groups was undertaken. Ten children with diplegic cerebral palsy with a mean age of ten years six months (7.11 to 13.9) had multi-level minimally invasive surgery and were matched for ambulatory level and compared with ten children with a mean age of 11 years four months (7.9 to 14.4) who had conventional single-event multi-level surgery. Gait kinematics, the Gillette Gait Index, isometric muscle strength and gross motor function were assessed before and 12 months after operation. The minimally invasive group had significantly reduced operation time and blood loss with a significantly improved time to mobilisation. There were no complications intra-operatively or during hospitalisation in either group. There was significant improvement in gait kinematics and the Gillette Gait Index in both groups with no difference between them. There was a trend to improved muscle strength in the multi-level group. There was no significant difference in gross motor function between the groups. We consider that minimally invasive single-event multi-level surgery can be achieved safely and effectively with significant advantages over conventional techniques in children with diplegic cerebral palsy

Hig energy fractures of the lower limb are often associated with tibial or femoral bone loss, skin exposition with vascular and nervous injuries (Gustilo et al.). The surgical procedure is a real challenge, consisting in a temporary stabilization of the fracture associated with a plastic and/or vascular reconstruction. Once the skin and vascular injuries are recovered, the orthopaedic surgeon can remove the temporary stabilization performing a circular external fixation with bone lengthening by using the “bifocal” (one site of metaphiseal corticotomy and one site of compression) or “trifocal” (two sites of metaphiseal corticotomy and one site of compression) technique. We use to do a “docking site” treatment when bone fragments are nearly in contact. Our experience indicates that circular external fixation, by using the Orthofix system, is a very useful and safe technique in the management of severe lower limb injuries. Our good clinical results lead us to suggest this surgical technique that allow to obtain a limb reconstruction, avoiding segment amputation

Ten patients, who were unsuitable for limb lengthening over an intramedullary nail, underwent lengthening with a submuscular locking plate. Their mean age at operation was 18.5 years (11 to 40). After fixing a locking plate submuscularly on the proximal segment, an external fixator was applied to lengthen the bone after corticotomy. Lengthening was at 1 mm/day and on reaching the target length, three or four screws were placed in the plate in the distal segment and the external fixator was removed. All patients achieved the pre-operative target length at a mean of 4.0 cm (3.2 to 5.5). The mean duration of external fixation was 61.6 days (45 to 113) and the mean external fixation index was 15.1 days/cm (13.2 to 20.5), which was less than one-third of the mean healing index (48 days/cm (41.3 to 55). There were only minor complications. Lengthening with a submuscular locking plate can successfully permit early removal of the fixator with fewer complications and is a useful alternative in children or when nailing is difficult

We investigated the effect of bone lengthening by callotasis on longitudinal growth of the tibia in rabbits. Ninety-nine five-week-old immature rabbits were divided into five groups according to the percentage of lengthening: group I, 10%; group II, 20%; group III, 30%; group IV, 40%; and group V, sham operation without lengthening. Corticotomy was performed at the proximal metaphysis of the left tibia and the right tibia was used as a control. The lengthening rate was 0.25 mm twice daily. Radiological, histomorphometric, and immunohistochemical studies were done on animals killed at the time of corticotomy, at the completion of lengthening, and thereafter every two weeks until 12 weeks. Tibial lengthening did not cause retardation of growth when the bone was lengthened by up to 20%. When the bone was lengthened by 30% or more, growth retardation was evident, and persisted until skeletal maturity

Conservative treatment of neoplastic bone lesions in paediatric patients may require the sacrifice of growth cartilage with subsequent hypometria or axial deviation of the lower limb. Segmental reconstructions can be made using acrylic cement and intramedullary nailing or allograft. In case of involvement of the joint, reconstruction can be performed with prosthesis or arthrodesis. These reconstruction techniques can lead to a progressive deformity associated with shortening of the limb. The resolution of legs discrepancy and axial defects in survived patients often requires more than one surgical procedure. In our Institute, the patients affected by aforementioned defects, are treated with axial or circular external fixator at completed skeletal growth. This paper refers complications and outcomes in five patients treated:. 1st case. Male, 10 years: osteosarcoma of the distal femur healed with residual shortening of 8 centimeters. – We proceeded with a double level lengthening (proximal femur and proximal tibia) using Ilizarov technique. 2nd case. Female, 8 years:distal femur osteosarcoma healed with a shortening of 6,5 centimeters. – We used the Ilizarov apparatus to achieve an elongation of cm. 7 on soft tissues allowing the subsequent bone replacement with allograft of appropriate length. 3rd case. Female, 9 years: Ewing sarcoma of the femoral shaft. The correction of the legs discrepancy (8 centimeters) was performed using the Ilizarov apparatus with a proximal tibial corticotomy. 4th case. Female, 11 years: distal femur osteosarcoma healed with residual shortening of 8 centimeters. – A gradual lengthening of soft tissues with recovery of the length leg allowed the insertion of a new allograft associated with vascularised fibula. 5th case. Male, 13 years: femoral fracture in fibrous dysplasia. Residual leg discrepancy of 5 centimeters treated with tibial lengthening by a proximal corticotomy and use of the Ilizarov apparatus. The results obtained in our patients show that the use of the external fixator increases the quality of life in long-term survivors

Planning of surgical correction in sequelae of vitamin D-resistant rickets preliminarily requires the management of the metabolic defect with appropriate measures. In fact, surgery perfomed with the patient in a compensated metabolic condition greatly contributes to the prevention of recurrences. The deformity most frequently observed is genu varum (where femur, tibia and fibula are usually all deformed), often combined with internal torsion. Compression-distraction systems (or circular external fixators) provide an easy control of the corticotomy fragments and a gradual correction of all kinds of deformity during the operative and post-operative phases. Careful pre-operative planning is necessary, which may require a multi-stage and/or a sequential strategy of management. Between 1988 and 2002, 16 cases of sequelae of vitamin D-resistant rickets, with combined angular and torsional lower limb deformities, were treated with monofocal or bifocal tibial or femoral corticotomy and gradual correction with compression-distraction devices. There were nine men and seven women, with a mean age of 15 years. The Ilizarov system was used in 14 cases; in two cases the Volkov-Oganesian system was employed. The mean follow-up time was 8 years (range 1 – 15 years). The anatomical and functional results have been highly satisfactory, with a very low complication rate. These techniques thus represent an excellent option in the management of such complex diseases

Aims: We wanted to study the outcome of bone transport by Ilizarovñs method in simple and complicated gap non-unions where other conventional methods have little role to play. Methods: Sixty-six consecutive patients with an age range of 23–64 years (58 males and 8 females) were included in this study. Forty-four patients (67%) had associated problems like infection, deformity and shortening along with gap non unions of varying length. All the patients were treated with ring þxators and the principles of Ilizarovñs treatment were adopted. Corticotomy was carried out in all the cases. Appropriate arrangement of apparatus assembly was done according to the requirement of individual gap non-unions. Follow up ranged from 6 to 46 months. Results: In all but three cases, union was achieved along with satisfactory correction of other associated problems. In one case the patient had previously undiagnosed hypothyroidism and showed signs of callus at corticotomy site after treatment with thyroxine. This patient lost to follow-up. Two other cases needed further surgery (Ilizarovñs ring þxator). In one case, cancellous bone grafting had to be carried out. In six tibial gap non-unions, residual equinus deformity persisted. Conclusions: Ilizarovñs method of bone transport is quite effective in treatment of gap non-unions associated with complex problems, where other methods have proven to be less successful

Fracture or periosteal elevation near epiphysis induces inflammatory vascularity which is reported in early bone lengthening literature. In this study, corticotomy and periosteal elevation were put to use to induce new inflammatory vessels as collaterals in an ischaemic limb. In this prospective investigation between May 1990 and May 2000, seventy-two patients suffering from severe occlusive arterial disease (44 TAO, 13 atherosclerosis, 11 Raynaud’s disease, and 4 diabetics), who had not responded to previous non-surgical or failed surgical treatment, and had progressively deteriorating ischemic limbs, were subjected to corticotomy near major neurovascular bundles and the periosteal elevation along the whole length of the bone. There was complete relief from rest pain and an indefinite postponement of amputation in sixty-one out of seventy two patients. Longest follow up is ten years and shortest is six months. This new approach is based on principle of inflammation which is the universal reparative biological process. Digital Subtraction Angiography (DSA) studies before and after operation convincingly showed the continuance of a new vascular collateral network across the affected arteries, a process, which saved the ischemic limbs from certain amputation. This new Inflammatory vascular leash acts as a biological ‘bypass’ and appears to be an answer to small and diffuse artery disease, where vascular reconstruction is otherwise impossible

Introduction and Aims: I was presented with a Land-mine victim with closed fracture of right talus, compound injury to left lower limb, and defect in heelpad. Distal third of tibia and most of hindfoot were missing. Left foot neurovascularly intact and he was able to move his toes. Aim: reconstruct left distal tibia to enable full weight-bearing. Method: Lower leg debrided. LRS applied, using proximal ring with Sheffield clamp and two rings around foot. Corticotomy of proximal tibia. Bone transport, 10 days later. Heel debridement, to clear necrotic bone. Two months later transported bone was 2cm from ankle. Sepsis controlled. Distal tibia beveled, bone transport continued. Docking procedure performed. Ex-fix adjusted, attaining compression of hindfoot and midfoot. Distal tibia and foot transported 4cm, to correct disproportion. Osteoset used for bone growth. During the following two years, length discrepancy resolved, sepsis manageable. X-rays showed two cortices between proximal tibia and transported tibia. Fixator removed two months later. Received orthotic boot. Results: In September 2003 the patient came for follow-up. There was no evidence of sepsis in the leg. He was full weight-bearing using an orthotic shoe and rocker bottom sole. There was no pain. He had left the army and was now working as a builder in his country of origin and putting in a whole day’s work. The length of the transported segment is approximately 14cm. It is now fully consolidated and four cortices are visible on x-ray. The fusion of the distal tibia into the foot is solid and no pain is experienced from that. Conclusion: Big defects in the distal tibia can be managed with a straight rail reconstruction system, using unifocal bone transport with proximal corticotomy
