Background. External fixation for a fracture-dislocation to a joint like the elbow, while maintaining joint mobility is currently done after identifying the center of rotation under X-ray guidance, when applying either a mono-lateral or a circular fixator. Current treatment. using the galaxy fixation system by Orthofix, the surgeon needs to correctly identify the center of rotation of the elbow under X-ray guidance on lateral views. If the center of rotation of the fixator is not aligned with that of the elbow joint, the assembly will not work, i.e. the elbow will be disrupted on trying to achieve flexion or extension movements. Figures (A, B, C and D) summarize the critical steps in identifying the centre of rotation (Courtesy of Orthofix Orthopedics International). New design. This new idea aims to propagate the principle of sliding external fixation applied on the extensor side of a joint, with the limbs of the fixator being able to slide in and out during joint extension and flexion respectively, without hindering the joint movement. Taking the ulno-humeral joint as an example, it is enough to apply the sliding

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

Management of compound fractures of the tibial diaphysis forms a large proportion of the trauma workload at Tygerberg Hospital. This prompted a prospective study to compare external fixation with unreamed intramedullary nailing in the treatment of grade-I, II, IIIA and IIIB compound fractures of the tibial diaphysis. For a year we followed up 18 skeletally mature patients. External fixation was used in eight patients, four of whom had grade II fractures, two grade IIIA and two grade IIIB. Ten fractures (two grade-I, one grade-II, two grade IIIA and five grade IIIA) were stabilised with an unreamed intramedullary nail. Except for the method of fixation, fracture care was the same: all patients received antibiotics on admission, primary fracture debridement occurred within 24 hours and redebridement within 48 to 72 hours of injury.

Background:. Recurrent or late presenting Tibia Vara is a complex clinical problem. In addition to the multiplanar deformity the disorder is often accompanied by obesity. Simple re-alignment osteotomy with acute correction is effective early in the disease. Its use in recurrent or severe deformities is limited by geometric constraints (mechanical axis translation), difficult fixation and the risk of compartment syndrome. Gradual correction with external fixation devices is a well-accepted technique in these cases. It has been shown to obtain accurate correction and provides stable fixation. This allows early weight bearing which facilitate consolidation and rehabilitation. Hexapod fixators are technically less demanding than standard Ilizarov techniques. The TLHex is a relatively new hexapod fixator available in South Africa. Frame pre-assembly allows easier mounting on a limb with complex deformity. The software allows for non-orthogonal mounting, which simplifies frame-mounting assessment. Double telescoping struts allow greater strut excursion and the outside mounting of struts on the ring increases mounting options for fixation elements. This is the first report on its use in Blount's disease. Purpose:. Evaluation of the result of gradual correction with the TLHex

Twenty patients with mean age 56 years with bicondylar tibial plateau fractures, were treated at the author’s institution with fine wire fixation over a three-year period. Ten followed road traffic accidents and four followed high-energy falls; The remainder mainly in the elderly resulted from a simple fall. There were four Schatzeker type V, and sixteen type VI. Four were open fractures (Gustilo grade III); Seven patients sustained associated fractures at the same time. They were treated according to a prospective protocol and were followed up for an average of thirty months, (11 – 51). The protocol included CT Scan Guided planning, closed reduction if possible and percutaneous interfragmentary screw fixation to reconstruct the articular surface, under image intensifier control; The
Introduction: Currently used small animal models of a critical size defect do not sufficiently simulate the biologically unreactive situation in an atrophic non-union. Furthermore, models using intramedullary nails are of little, and poorly standardised, biomechanical stability. This is a characteristic known to promote callus formation though, rather leading to a hypertrophic non-union. The aim of this study was to establish an atrophic non-union model in the rat femur under well defined biomechanical conditions and with minimised interactions between the processes in the healing zone and the implant by using external fixation. MATERIALS AND METHODS: 80 male Sprague Dawley rats were randomly divided into two groups (non-union vs. control). All animals received an osteotomy (app. 0.5 mm gap) of the left femur, stabilised with a custom made

In the treatment of acute elbow dislocation promising clinical results have been reported on articulated external fixation and surgical reconstruction of major joint stabilizers. However, it remains unclear whether or not surgical reconstruction of the major joint stabilizers sufficiently stabilizes the elbow joint or if augmentation by a hinged elbow fixator is beneficial to provide early stability and motion capacity. The aim of the present study was to compare the stabilizing potential of surgical reconstruction versus augmentation by a hinged external elbow in a model of sequentially induced intability of the elbow. Materials and Methods: 8 unpreserved human upper extremities were mounted to a testing apparatus which was integrated within a material testing machine. In a first series, varus and valgus moments were induced to the intact elbow joint at full extension, as well as at 30°, 60°, 90° and 120° of flexion and the mean angular displacement at 2.5, 5, an 7.5 Nm was calculated. Instability was then induced by sequentially dissecting the lateral and the medial collateral ligament, the radial head, and the posterior capsule. The elbow joint was then sequentially restabilized by osteosynthesis of the radial head and refixation of the lateral and medial collateral ligament using bone anchors. In each sequence, elbow stability was tested with and without augmentation by a hinged
We tested the hypothesis that it is possible to accelerate fracture healing by changing the mechanical environment used in current methods i.e., from initial rigidity or micromovement followed by dynamisation to initial macromovement followed by rigidity (micro-movement). It is accepted that callus formation requires movement at the fracture site and this callus response is limited to the first few weeks after fracture. Logically, early macromovement at the fracture site would be beneficial for callus formation. Additional callus is not produced by further movement. Indeed, it may be counter-productive, just as continuing movement around two ends of a wooden stick bonded with glue will retard and even prevent “union”. We postulate that continuing movement at the fracture site after the callus response has ceased will also delay union. As a result, rigidity rather than dynamisation is required in the later stage of fracture healing. After testing an animal model, we built an
To fully verify the reliability and reproducibility of an experimental method in generating standardized micromotion for the rat femur fracture model. A modularized experimental device has been developed that allows rat models to be used instead of large animal models, with the aim of reducing systematic errors and time and money constraints on grouping. The bench test was used to determine the difference between the measured and set values of the micromotion produced by this device under different simulated loading weights. The displacement of the fixator under different loading conditions was measured by compression tests, which was used to simulate the unexpected micromotion caused by the rat’s ambulation. In vivo preliminary experiments with a small sample size were used to test the feasibility and effectiveness of the whole experimental scheme and surgical scheme.Aims

Background: The treatment of extensive soft tissue injury with bony involvement due to orthopaedic trauma or other pathologic conditions has undergone great improvement in the last decade. The main fields that assisted with that progress are: the ability to transfer autogenous vascularized soft and/or bony tissues to the injured areas and the possibility to apply external fixation either statistically for acute stabilization of a limb or using dynamic frames to correct late occurring contractures or deformities. Objectives: To present our experience in treating young patients with severe, post traumatic or tumor resection soft tissue and bony injuries including bone loss and late joint contractures. That was treated by a combination of free vascularized flaps and static or dynamic circular external fixation with special emphasis on preplanning and technical issues critical for the success of such complex procedures. Methods: Seven patients were included in the study; six post traumatic patients who received free vascularized myocutaneous latissimum dorsi or fasciocutaneous anterolateral thigh flaps to the calf and foot. All six patients had an Ilizarov frame for initial stabilization; two of them needed late dynamic correction of equines with the frame. The seventh patient had surgery for removal of osteosarcoma and received a vascularized osteocutaneous fibula flap with fixation by Ilizarov frame, this patient also needed late dynamic frame application for equines correction. Results: The mean age at surgery was 11.6 years (range 7–14 years); mean follow up was 1.8 years (range 2 months – 3.4 years). All microvascular flaps but one survived where the patient with the failed latissimus dorsi flap had the second muscle transferred at the next day. One patient needed 2 vascular revisions. All bone flap showed solid union at 3 months post operatively. Four patients achieved plantigrade foot initially. The three patients with dynamic correction achieved plantigrade foot at frame removal. Complications: Equinus contracture of the ankle in three patients, injury to the vascular anastomosis in one patient. Pin tract infection in all patients that responded well to antibiotics.

The most common indication for knee arthrodesis is pain and instability in an unreconstructable knee following an infected knee arthroplasty. In this study, we compare the use of the Mayday arthrodesis nail (Ortho-dynamics, Christchurch, UK) versus external fixation, Orthofix (Berkshire UK) and Stryker Hoffman II (County Cork, Ireland). All patients in this study underwent arthrodesis between 1995 and 2006 at Conquest Hospital, Hastings. In group A, 11 patients underwent arthrodesis with a Mayday nail. In all cases, the indications were infected total knee replacements (TKR). Three of these patients previously had failed attempts at arthrodesis with external fixation devices. In group B, seven patients underwent arthrodesis using external fixation. In six patients, the indication was infected TKRs. Results were reviewed retrospectively, with union assessed both clinically and radiologically. The mean inpatient stay for the Mayday nail group was 23 days (range 8 – 45 days) compared with 76 days (range 34 – 122) for the external fixation group (p<
0.01, CI 95). Ten patients in group A went on to confirmed primary arthrodesis. One patient underwent revision arthrodesis with a Mayday nail and subsequently united. In group B only two patients achieved union. The rate of union was significantly greater in the Mayday nail group than the external fixation group (91% vs 29%, p<
0.01). Of those patients that achieved union, there was no difference in the time to fusion between groups. Our study supported the existing literature and found that the Mayday nail appeared more effective than monoaxial
Purpose of study: Aim was to evaluate the functional outcome of External fixation supplemented by K-wire fixation in communited fractures of lower end radius and compare the outcome in closed and open fractures treated by this method. Methods: External fixation along with K-wire fixation was done in 25 consecutive patients (mean age-41.9 years; range-20 to 72 years). According to Frykman’s classification, there were 3 Type VII fractures and 22 Type VIII fractures. 15 fractures were closed type, 4 were Open grade I, 4 were Open grade II and 2 were Open grade III according to Gustilo and Anderson classification. The mean follow-up period was 14.1 months (range- 6 to 25 months). Results: The mean union time was 7 weeks (range-5 to 8 weeks). Mean dorsiflexion was 37.6 degrees, mean palmar flexion was 44.4 degrees, mean ulnar deviation was 16.2 degrees, mean radial deviation was 14.2 degrees, mean supination was 73 degrees and mean pronation was 79 degrees. Comparison of union time, dorsiflexion, palmarflexion, ulnar deviation, radial deviation, supination and pronation between closed, Open grade I, Open grade II and Open grade III fractures revealed no significant difference. Significant radial shortening was observed in patients with open fractures (P=0.004). 1 patient developed schanz pin tract infection and late distal radioulnar joint subluxation was seen in 4 patients.

External fixation is widely used in orthopaedic
and trauma surgery. Infections around pin or wire sites, which are usually
localised, non-invasive, and are easily managed, are common. Occasionally,
more serious invasive complications such as necrotising fasciitis
(NF) and toxic shock syndrome (TSS) may occur. We retrospectively reviewed all patients who underwent external
fixation between 1997 and 2012 in our limb lengthening and reconstruction
programme. A total of eight patients (seven female and one male)
with a mean age of 20 years (5 to 45) in which pin/wire track infections
became limb- or life-threatening were identified. Of these, four
were due to TSS and four to NF. Their management is described. A
satisfactory outcome was obtained with early diagnosis and aggressive
medical and surgical treatment. Clinicians caring for patients who have external fixation and
in whom infection has developed should be aware of the possibility
of these more serious complications. Early diagnosis and aggressive
treatment are required in order to obtain a satisfactory outcome. Cite this article:
External fixation (EF) devices are commonly used in the management of complex skeletal trauma, as well as in elective limb reconstruction surgery for the management of congenital and acquired pathology. The subsequent removal of an EF is commonly performed under a general anaesthetic in an operating theatre. This practice is resource intensive and limits the amount of operating theatre time available for other surgical cases. We aimed to assess the use of regional anaesthesia as an alternative method of analgesia to facilitate EF removal in an outpatient setting. This prospective case series evaluated the first 20 consecutive cases of EF removal in the outpatient clinic between 10/06/22 to 16/09/22. Regional anaesthesia using ultrasound-guided blockade of peripheral nerves was administered using 1% lidocaine due to its rapid onset and short half-life. Patients were assessed for additional analgesia requirement, asked to evaluate their experience and perceived pain using the Visual Analogue Scale (VAS).Introduction

Aims. Impaired fracture repair in patients with type 2 diabetes mellitus (T2DM) is not fully understood. In this study, we aimed to characterize the local changes in gene expression (GE) associated with diabetic fracture. We used an unbiased approach to compare GE in the fracture callus of Zucker diabetic fatty (ZDF) rats relative to wild-type (WT) littermates at three weeks following femoral osteotomy. Methods. Zucker rats, WT and homozygous for leptin receptor mutation (ZDF), were fed a moderately high-fat diet to induce T2DM only in the ZDF animals. At ten weeks of age, open femoral fractures were simulated using a unilateral osteotomy stabilized with an
Tibial nonunion represents a spectrum of conditions
which are challenging to treat, and optimal management remains unclear
despite its high rate of incidence. We present 44 consecutive patients
with 46 stiff tibial nonunions, treated with hexapod external fixators
and distraction to achieve union and gradual deformity correction.
There were 31 men and 13 women with a mean age of 35 years (18 to
68) and a mean follow-up of 12 months (6 to 40). No tibial osteotomies
or bone graft procedures were performed. Bony union was achieved
after the initial surgery in 41 (89.1%) tibias. Four persistent
nonunions united after repeat treatment with closed hexapod distraction,
resulting in bony union in 45 (97.8%) patients. The mean time to
union was 23 weeks (11 to 49). Leg-length was restored to within
1 cm of the contralateral side in all tibias. Mechanical alignment
was restored to within 5° of normal in 42 (91.3%) tibias. Closed
distraction of stiff tibial nonunions can predictably lead to union
without further surgery or bone graft. In addition to generating
the required distraction to achieve union, hexapod circular external
fixators can accurately correct concurrent deformities and limb-length
discrepancies. Cite this article:
External fixation is useful for the treatment of selected injuries to the hand. Some authors have suggested that external fixation of a phalanx may tether the extensor hood, thereby hindering active movements and predisposing to permanent adhesions. There is no consensus as to the best site for placement of the pin to minimise these problems. This study was performed on cadaver specimens to investigate the influence of the pin site on the range of simulated active movement of the interphalangeal joint. The dorsal midline position produces least interference with the extensor mechanism; radial and ulnar to this, interdigitating oblique fibres prevent a clean longitudinal split in the direction of gliding thus limiting movement of the extensor hood. At the proximal phalanx, positioning of the pin just off the midline avoids the thickening of the proximal median hood, whereas at the middle phalanx, a true midline position utilises the bare area at its base.
The aim of the study was to test the biomechanical effectiveness of the radiolucent fixator “X-caliber”. For this reason, care was taken to include a heterogeneous group of leg fractures capable of treatment with external fixation. A multi-centre study was organized to taste the biomechanical effectiveness of the radiolucent synthesis device. Our centre was equipped with this external fix-ator, which is preassembled and completely radiolucent. The fixator is manufactured from a carbon fibre composite, with stainless steel cams and locking nuts, and aluminium alloy bushes. The fixator types comprise standard fixators, fixators with a periarticular ring attachment, and fixators with a swivel clamp for ankles. Between December 2000 and May 2002 the authors tasted the biomechanical effectiveness of the new fixators in 13 patients with leg fractures. After a follow up of 6 months, analysing the results of other centres the authors retook the utilization of the radiolucent fixator and, in this paper, relate their total experience until April 2004 in 42 patients with leg fractures.
Our clinical experience in treating lower limb deformities by external fixation started in 1982 by applying an Ilizarov external fixation frame. Correcting lower limb deformity by gaining the proper length and the optimal mechanical performance is of the outmost importance and essential for valid restoration of the articular function. We treated 145 patients: 25 patients affected by post-traumatic deformities; 12 patients affected by axial deviation of the knee; 82 patients affected by limb shortening and associated limb deformities; eight patients with lower limb deformities and shortening following pathological hip alterations; and 18 patients affected by severe foot deformities. It is important to stress that in congenital lower limb deformities both axial deviation and limb shortening contribute to the final picture of the deformity. Combined (hybrid) external fixation provides an adequate correction of the mechanical axis and a proper lengthening of the shorter limb by a corticotomy followed by a gradual distraction.
Arthrolysis and dynamic splinting have been used in the treatment of elbow contractures, but there is no standardised protocol for treatment of severe contractures with an arc of flexion <
30°. We present our results of radical arthrolysis with twin incisions with the use of a monolateral hinged fixator to treat very severe extra-articular contracture of the elbow. This retrospective study included 26 patients (15 males and 11 females) with a mean age of 30 years (12 to 60). The mean duration of stiffness was 9.1 months (5.4 to 18) with mean follow-up of 5.2 years (3.5 to 9.4). The mean pre-operative arc of movement was 15.6° (0° to 30°), with mean pre-operative flexion of 64.1° (30° to 120°) and mean pre-operative extension of 52.1° (10° to 90°). Post-operatively the mean arc improved to 102.4° (60° to 135°), the mean flexion improved to 119.1° (90° to 140°) and mean extension improved to 16.8° (0° to 30°) (p <
0.001). The Mayo elbow score improved from a mean of 45 (30 to 65) to 89 (75 to 100) points, and 13 had excellent, nine had good, three had fair and one had a poor result. We had one case of severe instability and one wound dehiscence which responded well to treatment. One case had deep infection with poor results which responded well to treatment. Our findings indicate that this method is very effective in the treatment of severe elbow contracture; however, a randomised controlled study is necessary for further evaluation.
All patients were allowed to weight bear from the first postoperative week. Physiotherapy was started immediately after operation and continued until normal knee and ankle function was regained. Dynamization was done in all cases 2 weeks before removal of frame. Following removal, the patients were advised to use crutches for an additional two weeks.
We studied the effectiveness of treatment with AO-Mini external þxator in complete articular fractures of distal radius, type 23-C. At the end of the follow-up, in 81% of cases the use of extremity was better than 75%, and 83% of patients were pain free. X-Ray: 10% had Distrophy, and 56% had some articular alterations. Four month post-operative, 54% were recovered, and at the end of the follow-up 68%, of cases the þnal disability is <

In our study we will review 28 patients suffering from mal- nonunion, whom were treated by an Ilizarov external fixation, and the results of the treatment concerning radiological alignment and consolidation rate.
Malunions were treated either with acute or gradual correction of the deformity, following low energy osteotomy. For hypertrophic nonunion and mal-nonunion in general only distraction compression technique (mono-focal) was used. Atrophic and infected nonunion were treated with a bifocal technique (so-called bone transport), except for one case treated with monofocal technique only.

The main weakness of the classical external þxator is the penetration of the bone, this conducting to the entrance of the pathogenic germs by their migration toward the pins. Despite the fact that the centromedullary synthesis is done after several weeks after the removal of the external þxator the risk of infection after the operation remains signiþcantly high. Considering these theoretical assumptions and experiencing in our current practice such complications we have started to use 3 years ago the pinless external þxator for the stabilization of the tibia fractures. Between 1999–2002 there were hospitalized and operated 213 patients with open tibia fractures, 28 being treated using the pinless external þxator. From those cases PEF was used for 9 patients with type II lesions, 8 patients with type IIIA lesions and 3 patients with type IIIB lesions. After resolving the soft tissue injuries (approx. 2 weeks) the external stabilization was converted to internal centromedullar solid stabilization, without the risks associated with the use of the classical external þxator. Our conclusion was that the external pinless þxator is less invasive, stable and realize a good adherence to the bone. This guarantees the centromedullary conversion of the osteosynthesis with minimal risks, as it doesnñt expose the medullar cavity of the shaft.
We would like to present this case series of 10 adolescent patients with displaced, closed diaphyseal tibial fractures managed using the Taylor Spatial Frame. Management options for these injuries include non-operative treatment, antegrade nailing, flexible nailing systems, plating and external circular fixation. External circular fixation allows anatomical reduction avoiding potential complications such as growth arrest associated with antegrade nailing and retained metal work with plating. Flexible nailing system and cast immobilisation are unreliable for precise anatomical reduction. With limited evidence as to the extent of post-traumatic deformity that is acceptable, combined with the limited remodeling potential that this patient group possess, the precision of percutaneous fixation with the Taylor Spatial Frame system has clear advantages. This is a retrospective analysis of 10 adolescent patients with a mean age of 14.5 years (range 13 to 16 years). Data collected includes fracture configuration, deformity both pre and post operatively compared to post frame removal, length of time in frame and complications. The data was gathered using the patient case notes and the Picture Archiving and Communications System. The mean time in frame was 15.5 weeks (range 11 to 22 weeks). One non-union in a cigarette smoker was successfully managed with a second Taylor Spatial Frame episode. Our conclusion was that with careful patient selection the Taylor Spatial Frame allows successful treatment of closed tibial fractures in adolescents, avoiding complications such as growth arrest and post-traumatic deformity as well as avoiding retained metalwork.
Introduction. The vast majority of orthopaedic surgeons use C-arm fluoroscopy in the operating theatre when building a circular
The main problem, in the follow up results is a lack of pronosupination that stresses the importance of a perfect reduction of distal radioulnar joint to begin early a phisiotherapy
We believe that a combination of the two fixation system allow an optimal external stabilization in the first week (So the therapist can move the patients in intensive care room). Secondary the internal fixator allows an anatomical reduction with a stable fixation in the secondary kinesiterapeutic time.
Introduction. Knee arthrodesis is a useful limb salvage technique to maintain function in patients with complex and infected total knee arthroplasties (TKA). There are a number of commonly used

Aims. We aimed to evaluate the health-related quality of life (HRQoL) in children with supracondylar humeral fractures (SCHFs), who were treated following the recommendations of the Paediatric Comprehensive AO Classification, and to assess if HRQoL was associated with AO fracture classification, or fixation with a lateral
Abstract. Congenital posteromedial bowing of tibia (CPMBT) progresses with decreasing deformity and increasing shortening. Lengthening in CPMBT has not been studied extensively. Our series compares duration and complications of lengthening in younger vs older children. Methods. 28 tibial lengthenings (23 patients) by a single surgeon, divided into two equal groups of 14 segments: group-A ≤ 5 years, Group-B > 5 years. Lengthening was done in all with
