Introduction. Fibrous dysplasia is a pathological condition, where normal medullary bone is replaced by fibrous tissue and small, woven specules of bone. Fibrous dysplasia can occur in epiphysis, metaphysis or diaphysis. Occationally, biopsy is necessary to establish the diagnosis. We present a review of operative treatment using the Ilizarov technique. The management of tibial fibrous dysplasia in children are curettage or subperiosteal resection to extra periosteal wide resection followed by bone transport. Materials and Methods. A total of 18 patients were treated between 2010 – 2020; 12 patients came with pain and 6 with pain and deformity. All patients were treated by Ilizarov technique. Age ranges from 4–14 years. 12 patients by enbloc excision and bone transportation and 6 patients were treated by osteotomy at the true apex of the deformity by introducing the k/wires in the medullary cavity with stable fixation by Ilizarov device. The longest duration for bone transport was 16 weeks (14–20 weeks) for application, after deformity correction was 20 weeks. We have never used any kind of bone grafts. Results. All the 18 patients were treated successfully by Ilizarov compression distraction device. The patients with localized tibial pathology with deformity had the shortest period on the Ilizarov apparatus, 14 weeks. Conclusions. Preservation and bone regeneration by distraction histogenesis constitutes a highly conservative limb saving surgery. Patients with bone defects of <10 cm, a great deal of preserved healthy tissue and good prognosis are good candidates for these methods

Introduction. Correction of multiplanar bone deformities in children is indicated for prevention of secondary orthopaedic complications. Different problems related to surgical intervention were reported: non-union, delayed union, recurrent deformity, refracture, nerve palsy and pin tract infection. The aim of this study was to show the results of children femur and tibia bowing deformities by Ilizarov technique. Materials and Methods. We analysed 27 cases of children femur and tibia bowing deformities under the age of 13 yrs. Simultaneous deformity correction in femur and tibia was done with Ilizarov device in ipsilateral side. Contralateral side was operated after 14 days. Results. The duration of Ilizarov fixation was 130 days on an average. The deformity correction was achieved with a proper alignment in all the cases. Conclusions. Bowing of femur and tibia can be corrected simultaneously by Ilizarov fixation with minimum complications. There were no recurrent deformities in our cases

Recent recommendations by the National Institute for Health and Care Excellence (NICE) suggest that all patients undergoing elective orthopaedic surgery should be assessed for the risk of venous thromboembolism (VTE). Little is known about the incidence of symptomatic VTE after elective external fixation. We studied a consecutive series of adult patients who had undergone elective Ilizarov surgery without routine pharmacological prophylaxis to establish the incidence of symptomatic VTE. . A review of a prospectively maintained database of consecutive patients who were treated between October 1998 and February 2011 identified 457 frames in 442 adults whose mean age was 42.6 years (16.0 to 84.6). There were 425 lower limb and 32 upper limb frames. The mean duration of treatment was 25.7 weeks (1.6 to 85.3). According to NICE guidelines all the patients had at least one risk factor for VTE, 246 had two, 172 had three and 31 had four or more. . One patient (0.23%) developed a pulmonary embolus after surgery and was later found to have an inherited thrombophilia. There were 27 deaths, all unrelated to VTE. The cost of providing VTE prophylaxis according to NICE guidelines in this group of patients would be £89 493.40 (£195.80 per patient) even if the cheapest recommended medication was used. . The rate of symptomatic VTE after Ilizarov surgery was low despite using no pharmacological prophylaxis. This study leads us to question whether NICE guidelines are applicable to these patients. .

Purpose. According to the National Institute for Clinical Excellence (NICE) a risk assessment for venous thromboembolism (VTE) should be conducted on all patients undergoing elective orthopaedic surgery. We looked at the patient outcome undergoing elective Ilizarov surgery in terms of symptomatic VTE occurring during or after frame management. Methods. We performed a retrospective chart review of all adult Ilizarov cases performed by a single surgeon between 2000–2011. Patient mortality was confirmed using the Demographics Batch Service. Results. There were 457 cases in 445 patients with a mean age of 42.6 years (range 16–84). There were 440 lower limb and 31 upper limb frames. 185 cases were for infection and 62 cases required flap coverage by plastic surgeons. There were 31 bone transports, 112 deformity corrections, 39 lengthening, 37 fusions, 48 stabilizations and 134 compression/distractions. The mean duration of frame treatment was 34 weeks (range 6–85). According to NICE guidelines all our cases had at least one risk factor for VTE; 243 had two, 200 had three and 28 had four or more. All cases received no pharmacological VTE prophylaxis (except 14 flap cases after 2009). There were three cases of VTE in two patients (one man with deep vein thrombosis and a 17 year-old girl with two pulmonary emboli). There were 23 deaths, all unrelated to VTE. The average cost of providing VTE prophylaxis according to NICE guidelines in this group would total £89,493.40 (£195.80 per patient). If only the first 28 days of frame treatment were covered the cost would be £14,231. Conclusion. Our reported incidence of VTE in Ilizarov surgery is low despite no pharmacological prophylaxis being used. This study challenges whether NICE guidelines are applicable to this particular group undergoing Ilizarov surgery

We present a retrospective review of a single-surgeon series of 30 consecutive lengthenings in 27 patients with congenital short femur using the Ilizarov technique performed between 1994 and 2005. The mean increase in length was 5.8 cm/18.65% (3.3 to 10.4, 9.7% to 48.8%), with a mean time in the frame of 223 days (75 to 363). By changing from a distal to a proximal osteotomy for lengthening, the mean range of knee movement was significantly increased from 98.1° to 124.2° (p = 0.041) and there was a trend towards a reduced requirement for quadricepsplasty, although this was not statistically significant (p = 0.07). The overall incidence of regenerate deformation or fracture requiring open reduction and internal fixation was similar in the distal and proximal osteotomy groups (56.7% and 53.8%, respectively). However, in the proximal osteotomy group, pre-placement of a Rush nail reduced this rate from 100% without a nail to 0% with a nail (p < 0.001). When comparing a distal osteotomy with a proximal one over a Rush nail for lengthening, there was a significant decrease in fracture rate from 58.8% to 0% (p = 0.043). We recommend that in this group of patients lengthening of the femur with an Ilizarov construct be carried out through a proximal osteotomy over a Rush nail. Lengthening should also be limited to a maximum of 6 cm during one treatment, or 20% of the original length of the femur, in order to reduce the risk of complications

Standard Ilizarov technique uses the tensioned olive wires to provide interfragmentary compression in the acute fracture setting and in non-union surgery. In osteopenic metaphyseal bone this can lead to the olive “cutting through” the thin attenuated cortex reducing compression and stability. We describe a technique placing a percutaneous 3 hole Synthes Mini-fragment plate against the outer cortex of the bone fragment. An olive wire is then placed through each of the outer two holes and through the bone fragment. The construct is then tensioned. This stops the olive cutting into the bone and allows increased compression which is particularly important in non-union surgery

We report our experience of a humanitarian mission to treat the earthquake victims of October 2005 in Pakistan. The team with their equipment, in two periods of four and ten days respectively, treated 26 fractures in 25 patients with the Ilizarov frame and principles. There were 21 III B open fractures and three Tscherne III closed fractures. Seventeen fractures were infected with discharging pus and non-viable bone. Injuries were treated aggressively using different Ilizarov techniques of reconstruction surgery. All but two open fractures required a plastic surgical procedure for wound cover. Three months post-operatively eight out of thirteen fractures which had been treated in the first four days of the visit were healed and corticotomy for bone lengthening, performed during the second 10 days period visit. All wounds have remained clean with no evidence of superficial or deep infection. Limb lengthening procedures are planned for the rest of the patients

Introduction

Reconstruction of large defect of tibia following infection is considered as one of the most difficult problem facing the orthopaedic surgeon. Amputation with modern prosthetic fitting is a salvage procedure to treat big defects, which gives a functional result with unpredictable psychological impact.

Materials & Methods

Between January 2000 and January 2021, 56 patients (30 males and 26 females) with big defects following infection and post traumatic injury of the tibia were treated. The mean age of the patients at the time of surgery was 20.5 years (4–24 years). The fibula was mobilized medially to fill the defect and was fixed with Ilizarov fixator. The average size of the defects reconstructed was 18.5 cm (17–20 cm).

Distal tibial bone loss involving the ankle is a devastating injury with few options for reconstruction. The purpose of our study was to look at the long term results of ilizarov technique used to achieve lengthening of tibia and fusion at the ankle. 17 cases (16 post traumatic and one post tumor resection) admitted to one institution between 1994 and 2003. 13 cases were done in bifocal and four in trifocal mode. The duration of follow up was 12 to 84 months The average age was 33 years (Range 7-71). The mean length of the defect was 4.5 cm (Range 1-12). Union of the fusion site occurred in 88 % (15/17) of the patients with mean duration to docking and union being 8 months. The mean time in fixator was 13 months (Range 5 to 29). Average number of surgeries per patient was 3.2. Five patients required free vascularised grafts before the index procedure and 4 patients required realignment at the docking site. Functional results – Fourteen (77.5%) of the patients could walk without support or bracing and twelve patients (71%) returned to same or modified occupation. Complications – Two non-union. Deformity – Fusion site equinus deformity occurred with non union after re-fracture in one case. There were 2 cases of residual fore-foot equinus. Residual low grade infection with discharging sinus was present in two patients. One patient needed change of wires for Pin tract infection. Our study showed 76% good and excellent scores on functional scoring but also demonstrates the high morbidity associated with this procedure. In spite of the steep learning curve and high complication rates the procedure can be undertaken in specialised centres for highly motivated patients to achieve good functional results

Humerus non-unions are difficult to treat, especially those with infected non-unions, bone loss, deformity, previous multiple surgeries and/or broken hardware. This paper presents our experience with the use of the Ilizarov frame with humerus non- unions.

Eight consecutive humerus non-unions were treated using the Ilizarov frame. Only loose or infected hardware was removed. The Ilizarov frame was applied using safe zones principles of Ilizarov, Catagni and Paley.

Aspetic non-unions were treated with deformity correction, sequential compression and distraction, bone grafting and intramedullary stabilisation for diaphyseal nonunions. Infected diaphyseal non-unions were treated intra-medullary reaming with or without excision of infected necrotic bone segment, followed by insertion of antibiotic cement rod and compression.

Elbow spanning frames were avoided for supracondylar non-unions. Fine wire fixation of the distal fragment was preferred instead. Free elbow movement was allowed.

There were two infected (diaphyseal) and six aseptic non-unions (four diaphyseal and two supracondylar) treated with this technique. Broken hardware was left in-situ in five cases.

The average time from the index injury was 14 months, with each case having had an average of 3.2 procedures, prior to the application of the Ilizarov frame.

Union was obtained in all cases. The average humerus shortening was 1.5 cm. There was no residual angular or rotational deformity. Infection was eliminated in both the infected non-unions.

Primary bone grafting was used in all aseptic nonunions. Additional bone grafting was needed as a secondary procedure in four cases prior to frame removal. T he average time spent in the frame was 4.5 months. The Ilizarov method is a useful option for the management of complex humerus non-unions. Patients learn to tolerate the fixator and can achieve functional shoulder and elbow range with the fixator.

We reviewed 78 femoral and tibial non-unions treated between January 1992 and December 2003. Of these, we classified 41 as complex non-unions, because of infection (22), bone loss or prior failed surgery to produce union. These were treated with Ilizarov frames. 39 of the 41 nonunions healed successfully at a median time of 11 months.

Using the ASAMI scoring system, we had 17 excellent, 14 good, 4 fair and 6 poor bone results. The functional results were excellent in 14, good in 14, fair in 2 and poor in 2. All but 2 patients were extremely satisfied with the results. The average cost of treatment to the treating hospital was approximately £30,000 per patient. In comparison the cost for a patient with a below-knee amputation was £999 per year. This would amount to a cost of £36,000 per patient in their lifetime.

There is therefore not a great difference between the cost of limb salvage and amputation. The difference that exists favours limb salvage, if patient selection can accurately predict the salvage of a useful limb. Early referral to tertiary centres would reduce the morbidity and the prolonged time off work. The results justify the expense but the NHS needs to make financial provision for reconstruction of complex nonunions.

Introduction. Infected big gap non-union of femur and tibia are difficult to treatment because of infection, bone loss, shortening, poor sift tissue over and deformity. Step by step management and definitive treatment by Ilizarov fixator was achieved in our cases. Materials and Methods. A long defect which is more than 10cm in femur and tibia because of infection and gap, tumor resection, traumatic loss, which is very difficult to treat by conventional method and that's why we treated that type defect by Tibialization of fibula with Ilizarov technique. Management of infected big gap non-union of the femur include debridement and bone transport by Ilizarov technique by using Ilizarov fixator we can correct deformities, regenerate new bone without bone grafting, correct LLD and patient can weight bear during the course of treatment. We retrospectively reviewed records of 246 consecutive patients who underwent distraction osteogenesis using Ilizarov compression-distraction device for infected big gap INU of femur and tibia from 2000 to 2020. Results. All healed with the application of Ilizarov fixator, 5 needed reapplications of Ilizarov to achieve 100% union. 210 were excellent, 25 good and 6 were fair by ASAMI criteria. Mean Ilizarov duration was 366 days (130–250). Mean 8.2 cm length was achieved in the regenerate. Conclusions. A well plan step by step Ilizarov technique to cover infected gap non-union of femur and tibia is an excellent method in challenging cases. Excellent results cannot be achieved with conventional methods but can be easily achieved with Ilizarov technique within 1–2 years

Introduction. The objective of this study is to report the first cases of femoral lengthening in children using Ilizarov fixator. Materials and Methods. We carried out a retrospective study about the cases of femoral lengthening done in 2010 to 2020 in our BARI-ILIZAROV Orthopaedic centre Dhaka. Results. 48 lengthening were done during this period using Ilizarov fixator. The procedure was done incongenital bone diseases in 20 cases and after a distal femoral epiphysiodesis in 10 cases. The mean age at surgery was 12.8 years. Lengthening was required in all patients and an axis correction was required in 16 of 26 cases. The mean lengthening was 5.9 cm. The healing index was 45.5 day/cm (25.5–62). We noticed 8 knee stiffness and 5 broken wires. Knee Stiffness were corrected by Judet'squadricepsplasty and 6 broken wires were replaced by new wires. The goal of lengthening was reached in all cases. The goal of axis correction was reached in 98.5% of cases. Conclusions. Ilizarov technique allows to do accurate lengthening and axis correction and it is a unique reliable external fixator for femoral lengthening in children

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

This study sought to determine if treatment of resistant clubfeet by the Ilizarov method influenced the pattern of recurrence. Forty-seven children were identified as having undergone treatment by the Ilizarov method. Inclusion criteria for treatment with the Ilizarov method were clubfeet belonging to diagnostic categories that had recognised tendencies for resistance to standard methods of clubfoot management or a previous history of soft tissue releases performed adequately but accompanied by rapid relapse. There were 60 feet with a mean follow-up of 133 months (46-224). Diagnoses included 34 idiopathic types, 7 arthrogryposis, 1 cerebral palsy, and 5 other. Summary statistics and survival analysis was used; failure was deemed as a recurrence of fixed deformity necessitating further correction. This definition parallels clinical practice where attainment of ‘normal’ feet in this group remains elusive, and mild to moderate relapses that remain passively correctable are kept under observation. Soft tissue releases were common primary or secondary procedures. The mean time to revision surgery, if a soft tissue release was undertaken as a primary procedure, was 36 months (SD 22), and 39 (SD 23) months if undertaken for the second time. This compares with 52 months (SD 32) if Ilizarov surgery was used. Using survival analysis, there is a 50% chance of a relapse sufficiently marked to need corrective surgery after 44 months following the first soft tissue release, 47 months if after the second soft tissue procedure and 120 months after the Ilizarov technique. We conclude that resistant club feet, defined as those belonging to diagnostic categories with known poor prognoses or those that succumb to an early relapse despite adequate soft tissue surgery, may have longer relapse-free intervals if treated by the Ilizarov method

Tibial fractures complicated by bone and/or soft tissue loss present a great challenge. Traditional methods of limb reconstruction are lengthy and may not yield satisfactory functional results. Despite its tremendous contribution to the management of this condition, the Ilizarov technique of bone transport has several problems and difficulties. The present study was carried out between 1997 and 2002 and included 21 patients with tibial fractures complicated by bone and soft tissue defects as a result of open fractures or surgical debridement of infected non-unions. The bone loss ranged from three to eleven cm. (average 4.7 cm.). Ages ranged from 12 to 54 years (average 28.8 years). The follow-up ranged from 24 to 75 months. The procedure included resection of all devitalised tissues, acute limb shortening to close the defect, application of the external fixator and metaphyseal osteotomy for re-lengthening. In all patients the fractures united with well aligned limbs. Acute limb shortening of up to six cm. was done in the lower third of the leg. Limb lengthening was done in all cases and ranged from 3 to 9.5 cm. (average 4 cm.). An Ilizarov external fixator was used in nine cases (41%) and a monolateral fixator in 13 cases (59%) with a total of 22 applications. Residual leg length discrepancy of more than 3cm. occurred in four cases (19%). Complications included one refracture, one transient peroneal nerve palsy and one equinus contracture of ten degrees. Satisfactory results were obtained in 93% of cases. Acute limb shortening and re-lengthening converts a complicated limb reconstruction into a relatively simpler one of linear limb lengthening, without the difficulties of traditional Ilizarov techniques and eliminated the need for soft tissue flaps. It is better instituted early in the management of these cases to ensure better functional results and shorter treatment time

Aim. Simultaneous use of Ilizarov techniques with transfer of free muscle flaps is not current standard practice. This may be due to concerns about duration of surgery, clearance of infection, potential flap failure or coordination of surgical teams. We investigated this combined technique in a consecutive series of complex tibial infections. Method. A single centre, consecutive series of 45 patients (mean age 48 years; range 19–85) were treated with a single stage operation to apply an Ilizarov frame for bone reconstruction and a free muscle flap for soft-tissue cover. All patients had a segmental bone defect in the tibia, after excision of infected bone and soft-tissue defects which could not be closed directly or with local flaps. We recorded comorbidities, Cierny-Mader and Weber-Cech classification, the Ilizarov method used, flap type, follow-up duration, time to union and complications. Results. 26 patients had osteomyelitis and 19 had infected non-union. Staphylococci were cultured in 25 cases and 17 had polymicrobial infections. Ilizarov monofocal compression was used in 14, monofocal distraction in 15, bifocal compression/distraction in 8, and bone transport in 8. 8/45 had an additional ankle fusion, 7/45 had an angular deformity corrected at the same time and 24 also had local antibiotic carriers inserted. Median time in frame was 5 months (3–14). 38 gracilis, 7 latissimus dorsi and 1 rectus abdominus flaps were used. One flap failed within 48 hours and was revised (flap failure rate 2.17%). There were no later flap complications. Flaps were not affected by distraction or bone transport. Mean follow-up was 23 months (10–89). 44/45 (97.8%) achieved bony union. Recurrence of infection occurred in 3 patients (6.7%). Secondary surgery was required to secure union with good alignment in 8 patients (17.8%; docking site surgery in 6, IM nailing in 2) and in 3 patients for infection recurrence. All were infection free at final follow-up. Conclusions. Simultaneous Ilizarov reconstruction with free muscle flap transfer is safe and effective in treating segmental infected tibial defects, and is not associated with an increased flap failure rate. It shortens overall time spent in treatment, with fewer operations per patient. However, initial theatre time is long and a committed multidisciplinary team is required to achieve good results

Aims. Ilizarov described four methods of treating non-unions but gave little information on the specific indications for each technique. He claimed, ‘infection burns in the fire of regeneration’ and suggested distraction osteogenesis could effectively treat infected non-unions. This study investigated a treatment algorithm for described Ilizarov methods in managing infected tibial non-union, using non-union mobility and segmental defect size to govern treatment choice. Primary outcome measures were infection eradication, bone union and ASAMI bone and function scores. Patients and Methods. A consecutive series of 79 patients with confirmed, infected tibial non-union, were treated with one of four Ilizarov protocols, consisting of; monofocal distraction (26 cases), monofocal compression (19), bifocal compression/distraction (16) and bone transport (18). Median non-union duration was 10 months (range 2–168). All patients had undergone at least one previous operation (mean 2.2; range 1–5), 38 had associated limb deformity and 49 had non-viable non-unions. Twenty-six cases (33%) had a new simultaneous muscle flap reconstruction at the time of Ilizarov surgery and 25 had pre-existing flaps reused. Treatment algorithm based on assessment of bone gap and non-union stiffness, measured after resection of non-viable bone. Results. The treatment algorithm was easy to apply, being based on easily assessable criteria. Infection was eradicated in 76 cases (96.2%) at a mean follow-up of 40.8 months (range 6–131). All three cases of infection recurrence occurred in the monofocal compression group. They required repeat excision and Ilizarov distraction in two cases and below-knee amputation in one. Union was achieved in 68 cases (86.1%) with the initial Ilizarov methods alone. Union was highest amongst the monofocal distraction and bifocal compression/distraction groups, 96.2% and 93.8% respectively. Mean external fixator time was 7.5 months (range 3–17). Monofocal compression was successful in only 73.7% of mobile non-unions, with significantly lower ASAMI scores and a 26.3% re-fracture rate. Bone transport secured union in 77.8% (14/18) but with a 44.4% unplanned reoperation rate. However, after further treatment, infection-free union following bone transport was 100%. Conclusion. We cannot recommend Ilizarov monofocal compression in the treatment of infected, mobile non-unions. Distraction (monofocal or bifocal) was effective and is associated with higher rates of union and infection clearance

Aims

The timing of when to remove a circular frame is crucial; early removal results in refracture or deformity, while late removal increases the patient morbidity and delay in return to work. This study was designed to assess the effectiveness of a staged reloading protocol. We report the incidence of mechanical failure following both single-stage and two stage reloading protocols and analyze the associated risk factors.

Methods

We identified consecutive patients from our departmental database. Both trauma and elective cases were included, of all ages, frame types, and pathologies who underwent circular frame treatment. Our protocol is either a single-stage or two-stage process implemented by defunctioning the frame, in order to progressively increase the weightbearing load through the bone, and promote full loading prior to frame removal. Before progression, through the process we monitor patients for any increase in pain and assess radiographs for deformity or refracture.
