Introduction. A clinical case of catastrophic ring failure in a 13 year old autistic overweight patient during treatment for tibial lengthening and deformity using a Taylor Spatial Frame is reported. Ring failure was noted during the later stages of bone healing and the frame was removed. The clinical outcome was not affected by the catastrophic ring failure. The photograph of the deformed ring is presented below:. Materials and Methods. The patient's notes and X-rays were reviewed and a macroscopic examination of the deformed ring was performed. Mechanical tests of different Taylor Spatial frame constructs were performed in an attempt to simulate the deformity that was clinically observed. Different constructs of TSF of different ring sizes were fixed to polyurethane cylinders simulating bone, were mechanically tested to failure and load/deflection curves were produced. Results. Macroscopically the ring looked otherwise normal. Gradual mechanical compression tests of Taylor Spatial frame constructs showed that ring deformation increased by increasing the ring diameter and by using jointed rather than full joints without a ring. The ring deformation observed clinically was reproduced at the lab by applying high loads on frame constructs composed of large diameter jointed rings not rigidly fixed to bone. Conclusions. Taylor Spatial frame ring failure during treatment is a serious complication that has not been described in the literature. Possible causes are discussed. Clinicians are advised to use the smaller possible diameter rings. Where large diameter rings are required, these rings should preferably be not jointed. Half rings when used should be carefully and securely joined together by the operating surgeon in order to make a complete ring. For any figures or tables, please contact the authors directly

Introduction. In my paediatric Orthopaedic practice I use Kirchner wires for the fixation of the TSF on bone. I noted a significant percentage of wire loosening during the post-operative period. The aim of this project was to establish the effectiveness of the wire clamping mechanism and find ways to reduce the incidence of wire loosening when using the TSF. Materials and Methods. In the first instance wire slippage was measured intra-operatively after the tensioner was removed using an intra-operative professional camera. Following this study mechanical tests were performed in the lab measuring the pull out properties of Kirchner wires using different bolts and different torque levels in order to tighten the wire on the fixator. Results. Our clinical study confirmed wire slippage intra-operatively immediately after the tensioner was removed. Wire slippage after the tensioner was removed was found to vary from 0.01 mm to 0.51 mm (mean 0.19 mm). Our mechanical tests showed that the ideal torque for tightening the wire on the frame using a bolt was around 15 N.m. A comparison between cannulated and slotted bolts suggested that cannulated bolts are more effective as a clamping mechanism. A comparison between aluminium made Taylor Spatial frame rings and stainless steel made Ilizarov rings suggested that the Taylor Spatial frame rings are more effective as part of a clamping mechanism. Conclusions. It is important that clinicians routinely measure the torque they use to clamp wires on circular external fixators. Clinicians and manufacturers are informed that the type of bolt used is important in maintaining wire tension. Manufacturers should design the ideal bolt which effectively grips the wire without the risk of fracture. The Ilizarov frame clamping mechanism can be effectively used with the Taylor Spatial frame

Purpose of study. The primary treatment of congenital talipes equinus varus with the Ponsetti method remains the gold standard of treatment. Relapsed, neglected and/or teratogenic clubfeet pose a significant treatment challenge as the long term outcome of posteromedial release surgery is poor. Advances in circular fixation offer predictable deformity correction without the need for extensive soft tissue release. The Taylor Spatial Frame utilizes the correction principles of the “Ponsetti Method”, but little literature exists describing the correction of relapsed clubfeet with these fixators. This study assesses the outcome of relapsed clubfeet treated with the Taylor Spatial Frame Circular fixator. Methods. Ethics approval was obtained for a prospective descriptive study (N10-10-338). Patients with clubfeet who met inclusion criteria were treated with a Taylor Spatial Frame. The International Clubfoot Study Group Score was used to assess the feet preoperatively and six months postoperative. This scoring system scores the morphology, functionality and radiographic parameters of the clubfoot. Quality of life was assessed by means of the Child Health Questionnaire. Results. Ten feet (6 bilateral, 4 unilateral) were included in the study. Seven male and three female patients with average age of 6 years (range 3 – 13 years, sd ±4) qualified for the study. Feet were scored using the International Clubfoot Study Group Score. All feet scored poor preoperatively (average score 37±6). Postoperatively two feet scored excellent, seven good and one fair (Average score 9±4). This was statistically significant, p=0.00000. Two patients required additional surgical procedures for residual deformity. Five patients had superficial pin tract infection and one tibia fracture occurred. Conclusion. Treatment of relapsed clubfeet with the Taylor Spatial Frame gives a predictable correction of deformities without the need for extensive soft tissue and bony procedures. TSF assisted clubfoot correction constitute a useful salvage treatment modality. NO DISCLOSURES

Introduction. Lower limb mal-alignment as a result of fracture malunion can result in knee degenerative arthritis or predispose to early arthroplasty failure due to the altered mechanical axis. The choice of corrective osteotomy is often determined by potential complications. Opening wedge osteotomy is associated with poor bone healing especially in adult diaphyseal bone. Distraction osteogenesis enables gradual deformity correction with the gap filled by regenerate bone. Bone formation however is formed less favourably in the diaphysis and metaphyseal osteotomy is advised. We present a consecutive series of adult tibial diaphyseal correction using the Taylor Spatial Frame utilising the method of distraction osteogenesis. Method. 15 adults, 11 male and 3 female, underwent tibial deformity correction. A mid diaphyseal osteotomy was made using minimal soft tissue dissection and an osteotome. The site was determined by the centre of rotation of angulation (CORA). After a 6 day latency period distraction was undertaken by the Taylor Spatial Frame. Patients were encouraged to fully weight bear throughout the treatment process. Following regenerate consolidation the frame was removed and a below knee weight bearing cast applied for 4 weeks. Result. A mean correction of 11 degrees (4∼19) was undertaken. Correction time was a mean 13.5 days (6∼22). All osteotomies consolidated and frame removal was after a mean 136 days (92–192). All patients had at least one superficial pin site infection which responded to oral antibiotics. There were no deep infections or significant complications. Conclusion. Deformity correction at the CORA produces realignment without translation. The Taylor Spatial Frame allows accurate virtual hinge placement and stable correction of adult bone. Concern over diaphyseal osteotomy in adult bone has been previously raised but our study confirms that tibial diaphyseal correction using distraction osteogenesis is successful with minimal morbidity and rapid return to function. We believe that this should be considered as the optimal technique when undertaking tibial diaphyseal deformity correction

Statement of Purpose. Our experience with Taylor Spatial Frame correction of complex foot deformities in children. Persistent foot deformity in congenital talipes equinovarus is a challenge. Open surgery is associated with complications including difficulty in achieving acute corrections in stiff, scarred feet. Gradual correction using the Ilizarov circular frame has been described as an alternative and we present the experience using a computer assisted hexapod gradual frame correction with the Taylor Spatial Frame (TSF). A retrospective audit of sequential patients treated by TSF was performed. Technique, outcome, complications and key learning points were recorded. 21 paediatric patients underwent 27 treatments with a Taylor Spatial frame for complex foot deformity correction. Average age 11 years with majority diagnosis of congenital talipes equinovarus. The deformities severity meant acute correction would result in either neurovascular or soft tissue compromise. Plantigrade feet with good function was achieved in 22 feet. 3 feet were deemed as failures. 2 feet have residual deformity but acceptable function. According to Paley's classification, there were 4 complications, 7 obstacles and 35 difficulties (pin tract infection and pain management). Complications did contribute to poorer outcomes. The key learning points were: protection of the ankle joint and distal tibial physis; staged osteotomy reduces swelling and complication rates; and consideration of further procedures at frame removal is important. Finally a thorough preoperative counselling programme should be instituted and patients warned of the time commitment and high difficulty rates associated with treatment. Managing patient expectation with goals is as important as meticulous surgery. Although complication rates were high, the majority of treatment goals were met, therefore the TSF is valid in the treatment of complex deformities in the foot. Most patients with severe deformity can achieve a plantigrade functional foot but residual stiffness and need for minor orthotics is almost universal

We have treated 17 patients with bone defects of the tibia by internal bone transport using a stacked Taylor Spatial Frame. There were 12 cases of infected non unions, 2 cases of osteomyelitis, 1 case of acute traumatic bone loss, 1 case of non union in a patient with neurofibromatosis, and 1 case of pseudoarthrosis of the tibia. The mean bone defect was 51.8mm (range 10–100mm). Leg length has been restored to within 10mm in 16 cases and to within 15mm in one case. All patients have united. Residual deformity at the docking site or regenerate was negligible in 4 patients and less than 5 degrees in any plane in the remaining 13 patients. There have been two cases of re-fracture which have united with conservative treatment and 1 case of partial peroneal nerve palsy which is recovering. The use of a stacked Taylor Spatial Frame system is effective in mediating bone transport resulting in predictable regenerate, accurate docking and minimal induced bone deformity

Introduction. Charcot Arthropathy related foot and ankle deformities are a serious challenge. Surgical treatment of these deformities is now well established. The traditional surgical method of extensive surgical exposure, excision of bone, acute correction and internal fixation is not always appropriate in presence of active ulceration, deep infection and poor bone quality. Minimally invasive osteotomies and gradual correction of deformities with a circular frame are proving helpful in minimizing complications. We present our experience with the use of Taylor Spatial Frame (TSF) in 10 patients with recurrent ulceration and deformity. Materials and Methods. Our indication for the treatment with TSF is recurrent or intractable ulceration with or without active bone infection or a history of infection in a deformed foot and/or ankle. There are 2 female and 8 male patients in this cohort. We used a long bone module for ankle and hindfoot deformities (3 patients) and a forefoot 6×6 butt frame (7 patients) for midfoot deformities. An osteotomy through midfoot was performed in all chronic stable midfoot deformity cases and a calcaneal osteotomy and gradual correction through ankle in when hindfoot and ankle deformities co-existed. Results. Our outcome measures are a complete healing of ulcer and infection without recurrence, clinically plantigrade foot and ability to wear regular shoes or diabetic footwear. We achieved this outcome in 9 out of 10 patients. Successful patients remain ulcer free at minimum 7 and maximum 14 years follow up. Complications included eight episodes of pin infection that responded to oral antibiotics only and two pin breakages. Conclusions. Our results confirm that Taylor Spatial Frame treatment is a good alternative to traditional surgery in high-risk complex Charcot neuroarthropathy foot and ankle deformities

Purpose of the study. To assess use of Taylor Spatial Frame to correct posttraumatic equinus contracture of ankle by soft tissue distraction. Description of a successful technique. Methods and end results. We have treated five cases of severe and resistant equinus contracture (20–30 degrees) between 2005 and 2010. All cases resulted from severe soft tissue injury and compartment syndrome of affected limb. They had undergone prolonged treatment for open fracture of tibia prior to referral to our institute and failed to respond to at least six months of aggressive physiotherapy. In all cases fractures did not involve ankle articular surface and all tibial fractures had united. Three out five cases also had associated peroneal nerve palsy. Our procedure included Tendo Achilles Lengthening, ankle and subtalar capsulotomy and application of two-ring Taylor Spatial Frame. We used long bone module to correct the deformity gradually. All deformities were over corrected by 5–10% to prevent recurrence. We successfully corrected equinus deformity in all cases. Follow up ranged from three months to five years and we found no recurrence. Patients with peroneal palsy were provided with Ankle Foot Orthosis (AFO). Conclusion. Taylor Spatial Frame treatment provides a safe, finely controllable, accurate and reproducible method of correcting soft tissue equinus deformity

Background. Severe infantile Blount's disease can result in a multiplanar deformity of the proximal tibia with both intra-articular and metaphyseal components. Correction can represent a significant surgical challenge. We describe our results using the Taylor spatial frame for acute tibial hemiplateau elevation combined with gradual metaphyseal correction in patients with severe infantile blounts with an associated physeal bony bar. Methods. Eight patients (10 knees) underwent tibial hemiplateau elevation and metaphyseal correction with use of the Taylor Spatial Frame between 2012–2016. We undertook a retrospective case note and radiographic review of all patients to assess clinical and radiographic outcomes. Mean age at the time of surgery of was 11.7 years and mean length of follow up was 16.8 months. Results. At time of latest follow up all patients reported no hip, knee or ankle pain. All knees were clinically stable without lateral thrust during gait. Improvement in radiographic parameters was seen in all patients. The mean tibiofemoral angle improved from −28.3 to 5.9 degrees post operatively. The angle between femoral condyles and the tibial shaft improved from a mean of 56.3 degrees to 90.3 degrees. The joint depression angle was also seen to improve from mean 47.4 degrees to 9.8 degrees. No significant complications were seen. Conclusion. This technique has been shown to be an effective method of correction of the complex deformity encountered in severe infantile Blount's disease. Use of the Taylor spatial frame may provide certain advantages in comparison to previously described approaches. Level of Evidence: Level IV (Case Series)

Treatment of tibial osteomyelitis can be challenging and lengthy, with numerous complications possible during rehabilitation. We report on the usage of the Taylor Spatial Frame (TSF) for a large cohort of patients, and analyse factors that affect outcomes. Between 2015-2020, 51 patients were treated with TSF for osteomyelitis at a major trauma centre. Demographic, infection and treatment factors of: age, smoking status, diabetes, and BMI, acute (<6 weeks post injury) or chronic (>6 weeks) osteomyelitis, bacteria isolated, time to debridement, therapy/surgery number of TSF, time TSF was in, antibiotic treatment period, time to partial weight bear (PWB) and full weight bear (FWB) prescriptions, were collected. Outcomes of complications and time to union were obtained. Radiological union was achieved at mean 11.0 months. Mean follow up was 24.1 months. Six and three patients were further treated with fusion and amputation respectively. Mean treatment time with TSF was 12.1 months. 78% had some complications, with pin site infection, malunion, and non-union being most prevalent. Univariate factor analysis, multicollinearity diagnostics, then multivariate model construction were performed. Staphylococcus Epidermidis in bone debridement microbiology was significantly negatively associated with pin site infection (OR 0.093, 95% CI 0.011-0.828) and malunion (OR 0.698, 95% CI 0.573-0.849), and enterococcus with non-union (OR 0.775, 95% CI 0.656-0.916), during the treatment period. Time to union was significantly positively associated with time from admission to debridement (p=0.035), time TSF was in (p=0.021), presence of complications (p=0.045), bone loss complication(p=0.037), time to FWB prescription(p=0.001). We have analysed the effectiveness of TSF in the treatment of tibial osteomyelitis, and elucidated important injury, treatment and rehabilitation factors that affect outcome. The negative bacterial-complication cross associations could be due to successful eradication as culture specific antibiotics were used postoperatively. Earlier patient full weight bearing could enhance callous formation leading to faster union

Introduction. Open fractures are fortunately rare but pose an even greater challenge due to poor soft tissues, in addition to poor bone quality. Co-morbidities and pre-existing medical conditions, in particular, peripheral vascular diseases make them often unsuitable for free flaps. We present our experience in treating severe open fractures of tibia with Acute Intentional Deformation (AID) to close the soft tissues followed by gradual correction of deformity to achieve anatomical alignment of the tibia and fracture healing with Taylor Spatial Frame. Materials and Methods. We treated 4 geriatric (3 female and 1 male) patients with Gustillo-Anderson III B fractures of the tibia between 2017–18. All were unfit to undergo orthoplastic procedures (free flap or local flaps). The age range is 69 yrs to 92 years. Co-morbidities included severe rheumatoid arthritis, multiple sclerosis and heart failure. The procedure involved wound debridement, application of two ring Taylor Spatial Frame, acute deformation of the limb on the table to achieve soft-tissue closure/approximation. Regular neurovascular assessments were performed in the immediate post-operative period to monitor for compartment syndrome and nerve compression symptoms. After 7–10 days of latent period, the frame was gradually manipulated, according to a method we had previously published, to achieve anatomical alignment. The frame was removed in clinic after fracture healing. Results. Time in frame ranged from 1.5 months to 7 months. In one patient (92 yr old with an open fracture of the ankle) hindfoot nail was inserted after soft-tissue closure was achieved at 1.5 months, and frame removed. We achieved complete healing of soft tissue wounds without any input from plastic surgeons in all patients. All fractures healed in anatomical alignment. 3 patients had one episode of superficial pin infection each requiring 5 days of oral antibiotics. None of the patients developed a deep infection. Conclusions. Acute intentional deformation (AID) with Taylor Spatial Frame achieves good closure of soft tissues in physiologically compromised geriatric patients who were deemed unfit for plastic surgery. We also achieved fracture healing in all four cases without any major complications

We present our experience of lower limb reconstruction for patients with obvious defects in the tibia, by bone transport using a stacked Taylor Spatial Frame. A retrospective review of 40 patients treated between 2003 and 2009. There were 19 cases of infected non union, 9 cases of acute bone loss following fracture, 6 cases of chronic osteomyelitis, 4 cases of aseptic non union, 1 case of neurofibromatosis and 1 case of a loose and infected total ankle replacement. Twenty-eight out of the 40 patients reviewed have completed their treatment. Of these 28 patients, bony union was achieved in 23 patients, of whom 22 were assessed at discharge to have regained good to excellent limb function, a functional assessment was not available for review in the remaining patient. In 5 patients, docking site union failed, 3 of whom then underwent below knee amputation. Two patients required treatment with an intramedullary nail following frame treatment to achieve consolidated union of the docking site. Anatomic sagittal and coronal alignment was achieved in 19 out of 23 patients. The mean bone regenerate was 53.3 mm (range: 15-180mm), with a mean healing index of 9.2 days/mm (range: 4.4-25 days/mm). The majority of patients experienced at least one complication, these included pin site and soft tissue infections, refracture, nerve palsy and joint stiffness. Surgical stimulation of the docking site was required in 12 of the 28 patients to promote union. The use of a stacked Taylor Spatial Frame system is effective for restoring bone length and limb function in patients with bone loss following complex trauma and orthopaedic cases. The computer assisted nature of the spatial frame allows for predictable bone regenerate, minimal residual deformity and accurate bone docking

Introduction. The use of the Taylor Spatial Frame (TSF) in the management of tibial fractures and deformity correction is well established in the literature, however the majority of published papers are small in patient number. The aim of the project was to evaluate clinical and radiographic outcomes of patients with tibial fractures treated with a TSF. Materials and Methods. A retrospective analysis of patient records and radiographs was performed to obtain patient data, information on injury sustained, the operative technique used, frame construct, time duration in frame, union rates and complications of treatment. Results. In total, 111 tibial fractures managed with a TSF between 2009 and 2020 were reviewed. 55 were open fractures and 56 were closed. Overall union rate was 93.5%. Average time spent in the frame was 27.9 weeks. Complications included 4.6% deep infection rate, 3.7% of patients required component exchange and 8.3% required frame adjustment in theatre. Conclusions. The TSF is an effective way of managing tibial fractures. Our data has found high union rates when used in the management of both closed and open injuries with a low complication rate. Further data collection and analysis will help to aid the patient experience and clinical practice

To determine the effectiveness of six-axis analysis deformity correction using the Taylor Spatial Frame for the treatment of post-traumatic tibial malunions and non-unions, the study design was a retrospectively reviewed, consecutive series. Mean duration of follow-up: 3.2 years (range 2–4.2 years). All patients had been referred to a tertiary referral centre for deformity correction. Eighteen patients were included in the study (11 mal-unions and 7 nonunions). All deformities were post-traumatic in nature. The mean number of operations prior to the application of the spatial frame was 2.6 (range 1–6 operations). All patients completed the study. Six-axis analysis deformity correction using the Taylor Spatial Frame (Smith & Nephew, Memphis, TN) was used for correction of post-traumatic tibial malunion or nonunion. Nine patients had bone grafting at the time of frame application. One patient with a tibial plafond fracture simultaneously had deformity correction and an ankle fusion for a mobile atrophic nonunion. Two patients had infected tibial nonunions that were treated with multiple debridements, antibiotic beads, and bone grafting at the time of spatial frame application. A rotational gastrocnemius flap was used to cover a proximal third tibial defect in one patient. The average length of time the spatial frame was worn, time to healing, was 18.5 weeks (range 12–32 weeks). The main outcome measurements involved assessment of deformity correction in six axes, knee and ankle range of motion, incidence of infection, and return to preinjury activities. Results: Seventeen of the 18 patients treated with the Taylor Spatial Frame, with adjunctive bone graft as necessary, achieved union and significant correction of their deformities in six axes, i.e. coronal angulation and translation, sagittal angulation and translation, rotation, and shortening. Fifteen of the 18 patients returned to their pre-injury activities at last follow-up. Conclusion: Six-axis analysis deformity correction using the Taylor Spatial Frame is an effective technique in treating post-traumatic malunions and nonunions of the tibia, with several advantages over previously used devices

The Taylor Spatial Frame is a new external ring fixation system for correction of multi-planar deformities of the extremities. We report the first 100 consecutive cases treated with this system at the Bristol Limb Reconstruction Unit from November 1999. The Taylor Spatial Frame incorporates the technology of a virtual hinge and a Stewart Gough Platform. With the use of computer software it is capable of adjustments to within 1 degree and 0.5mm accuracy. Deformities are measured on plain radiographs. Required corrections over any period of time are calculated and a printed prescriptiion of daily adjustments is given to the patients to perform themselves at home. The following conditions were treated: Non-union (44), malunion (16), Leg length discrepancy (14), limb deformity (13), and acute fractures (13). The aims of frame treatment were non-union treatment (28), bone transport (12), acute fracture healing (12), correction of deformity (28), leg lengthening (15), and arthrodesis (5). Most cases involved the tibia (77) but the frame was also used on the femur (13), knee (3), ankle (4), humerus (2), and forearm (1). Complete correction of deformity was achieved in all but 7 patients. Union was achieved in 99 cases. All non unions united without bone graft. Mean transport of 46mm and lengthening of 38mm was achieved. 1 arthrodesis failed to unite. All fractures united without any residual deformity. Mean treatment time was 169 days (range 43 to 401). There was 100% compliance with patients performing adjustments themselves. Minor pin site problems were common (34 patients) but only 3 required debridement. Other problems included wire breakage (10), pain (3), peroneal nerve palsy (1) and DVT (1). 15 knees and 11 ankles developed stiffness which resolved. This study demonstrates the role of the Taylor Spatial Frame as an extremely versatile, accurate and safe new tool at the orthopaedic surgeon’s disposal in limb reconstruction and trauma surgery

Opening wedge proximal tibial osteotomy has become more popular in recent years, particularly in the management of medial compartment osteoarthritis. Unfortunately, fixation failures and/or non-unions of this osteotomy still occur. The aim of this study is to review two cases of failed opening wedge osteotomies salvaged with the Taylor Spatial frame. Both cases were reviewed clinically and radiographically and an analysis of their deformity was carried out. If required, metalware was removed and the Spatial frame applied and the deformity gradually corrected with either repeat osteotomy (case 1) or distraction of the non-union (case 2) until ideal alignment had been achieved. When the osteotomy regenerate had satisfactorily hardened, the frame was removed, and the patients were initially protected in a range of motion brace. Both patients achieved the desired correction of their deformities and union of their osteotomies, and had the frames removed at an average of 124 days following application. The Taylor Spatial frame is a very powerful tool for correcting complex multi-apical deformities in the juxta-articular region of the proximal tibia through minimally invasive techniques

Purpose: To assess the efficacy of the Taylor Spatial Frame in the correction of rigid long standing foot deformities in older children. Method: Children presenting with rigid longstanding foot deformities were fitted with a Taylor Spatial Frame (TSF) utilizing specialized small foot rings. Prior to surgery an operative plan was devised including soft tissue release and osteotomies usually consisting of a curved midfoot osteotomy and a dome shaped hind foot osteotomy. About 30% correction was obtained at surgery and held with the TSF. Postoperatively a computerized program of correction over a period of 8 weeks was calculated for each foot beginning 5 days after surgery and including an initial lengthening at each osteotomy site of 1 cm. Results: A total of eight feet have been corrected utilizing this technique with the TSF. All feet have been successfully returned to a plantigrade position enabling the child to don normal footwear. Ankle-foot orthosis are utilized for one year following surgery. Although the feet are stiff none are painful and all children arev fully ambulatory and weight bearing. All have at least 10 degrees of ankle motion which is improving with time. Families have been very pleased with the improved anatomical appearance of the feet as well as the child’s ability to use normal footwear. Conclusion: The Taylor Spatial Frame is an efficient and safe method to effect excellent correction of a rigid club foot deformity in combination with osteotomies and soft tissue releases of the foot

The implementation of standards for deformity correction planning of axial deformities and leg length discrepancy in paediatric orthopaedics and posttraumatic cases have improved the results of postoperative alignment and joint orientation. A variety of externally and internally applicable devices have been developed for limb lengthening and deformity correction. One of the most recent developments is the Taylor Spatial Frame Fixator based on a hexapod system and a computer software for deformity correction. But little is published about clinical results using this sophisticated technique and its possible advantages over other traditional unilateral fixators or ring systems. In times of difficulties financing our health care systems, a surgeons choice for a comparatively costly system should be based on qualified data. The aim of the present study was to compare the results of deformity correction and limb lengthening using a Taylor Spatial Frame with those of other ring fixators or unilateral systems. Between 1996 and 2004, 72 deformity corrections and/or limb lenghtenings have been performed on 52 patients with the unilateral Orthofix system (n=32), the Ilizarov system (n=22) and the TSF device (n=18). Statistical analysis showed a direct correlation between the healing index and the age at operation, as well as between the lengthening distance and the rate of complications. There were no significant differences of the healing index between all three fixators and the number of complications between the Ilizarov and TSF device, but the unilateral Orthofix fixator showed significantly more axial deviations during distraction osteogenesis. The Taylor Spatial Frame is easier to handle than the Ilizarov fixator but did not show superior results in clinical use

Purpose of the study. To use a simple way of manipulating Taylor Spatial Frame to achieve soft tissue closure by acute intentional deformation and then gradually achieving anatomical alignment of the fracture without complex deformity and frame parameters. Methods and end results. 10 consecutive cases of Gustillo III B open fractures of tibia and of soft tissue defect due to infected implant were treated with a new technique of acute intentional deformation using Taylor Spatial frame to successfully close the soft tissue defect without plastic surgery. We describe a new simple technique of achieving anatomical alignment of the fracture after creating complex deformity to close the soft tissue defect. We achieved complete full thickness cover of the exposed bone in all cases without plastic surgery and restored the bone to anatomical alignment. Only one patient needed additional Taylor Spatial Frame total residual prescription to correct minor residual deformity. Conclusion. We describe a simple way of using Taylor Spatial Frame (TSF) for acute deformation of Gustilo IIIB tibial fractures and other tibial defects in order to close soft tissue defects and gradual correction to the anatomical alignment. We have used the Direct Scheduler Utility module of the web-based software for Taylor Spatial Frames (TSF) to successfully restore the anatomical alignment
