Abstract Bone regeneration obtained by distraction osteogenesis is influenced by a series of factors. These include factors that are related to the mechanical stability of the system of distraction ...(internal or external devices), and to factors directly depending on the biology of the bone tissue, such as the method of bone interruption (osteotomy), the delay and rhythm of distraction, the anatomical site of the osteotomy, and the histological characteristics of the bone requiring reconstruction. The stability of the system of bone fixation depends on the rigidity of the frame, the connexion of the apparatus to the bone (wires, pins) and the intrinsic stability of the segment (length and level of maturation of bone regenerate). The radiological characteristics of bone regeneration (hypo- or hypertrophy) lead to the adaptation of the rhythm of distraction. Following more than 28 years of experience of application of the Ilizarov method for bone reconstruction, the authors describe the technique of frame assembly and the methods of evaluation and treatment of the complications of new bone formation.

Supracondylar fracture malunion usually results in cubitus varus deformity. The long-standing unsightly deformity causes psychological stress to the child and his/her parents in addition to biomechanical disturbances and functional disorders in the affected elbow. The optimal timing of corrective osteotomy is not well-established in the literature. The present study aimed to report the results of early correction of cubitus varus deformity using a simple technique and to focus on the timing of early correction after supracondylar fracture malunion.
Thirty consecutive patients treated for recent cubitus varus deformity after malunited supracondylar fractures, in the period between January 2012 and August 2017, were retrospectively reviewed. All patients had early surgical correction of the deformity within one year after the initial injury. In patients who presented with maluniting supracondylar fracture, the fracture was splinted until union was achieved, then active exercises were encouraged until elbow ROM was regained. The deformity was then corrected with a lateral closing wedge (LCW) osteotomy and fixed with two lateral and one medial wire.
All the osteotomies united. All the deformities were corrected. The humerus-elbow-wrist (HEW) angle significantly improved compared to the pre-operative values (p<0.001). All patients achieved satisfactory results at the final evaluation. Twenty-six patients (86.7%) achieved excellent results while four patients (13.3%) achieved good results.
Early correction of cubitus varus deformity avoids the psychological stress of the long-standing unsightly deformity to the young child and his/her family. It also avoids the delayed biomechanical and functional disturbances to the affected elbow. The LCW osteotomy and the three-wires fixation technique are simple and effective to correct the deformity and maintain the correction.
Background
Fibular hemimelia is partial or total aplasia of the fibula; it represents the most frequent congenital defect of the long bones. It usually is associated with other anomalies of the ...tibia, femur, and foot.
Questions/purposes
We reviewed 32 patients with Type III fibular hemimelia treated by successive lower limb lengthening and deformity correction using the Ilizarov method. We had three aims; first, to analyze complications, including the need for reoperation. The second was to assess knee and ankle function, specifically addressing knee ROM and stability and function of the foot and ankle. The third was assessment of overall patient satisfaction.
Patients and Methods
Thirty-two patients underwent 56 tibia lengthenings and 14 ipsilateral femoral lengthenings. Their mean age and mean functional leg-length discrepancy at initial treatment were 6.7 years and 6.2 cm, respectively. Activity level, pain, patient satisfaction with function, pain, and cosmesis, complications, and residual length discrepancy were assessed at the end of treatment.
Results
The mean number of surgeries was six per case. The healing index was 44.9 days/cm. Although complications were observed during 60 lengthenings (82%), the highly versatile system overcame most of them. Nearly equal limb length and a plantigrade foot were achieved by 16 patients. For two patients, a Syme’s amputation was performed. The outcome was considered satisfactory in 17 patients (53%) and relatively good in eight patients (25%).
Conclusions
The Ilizarov technique has satisfactory results for treatment of Type III congenital fibular hemimelia and can be considered a good alternative to amputation.

Arthrodesis is the most common salvage procedure for failed first metatarsophalangeal joint replacement arthroplasty. However, such procedure is not without limitations. Hereafter, we present the ...first case of replacement arthroplasty by distraction lengthening without associated arthrodesis as a salvage procedure for a failed first metatarsophalangeal joint replacement arthroplasty.
Background Surgical arthrodesis of the elbow joint is frequently unsuccessful and rarely performed. It is the purpose of this article to evaluate tactics and different constructs to achieve elbow ...arthrodesis (EA) using the Ilizarov apparatus in patients with post-traumatic nonreconstructable elbow sequelae. Methods A consecutive series of 4 patients were treated between 2009 and 2013 (3 men and 1 woman; mean age, 46.7 35-75 years). Two patients had late complications in total elbow replacement and developed nonunion after condylar fractures of the distal humerus. There were 3 ulnohumeral arthrodeses and 1 radiohumeral arthrodesis. The hybrid advanced Ilizarov technique was used in all cases. Results Complete union was obtained in 3 EAs (75%) without additional surgery at an average of 23 weeks. Fusion angles ranged from 90° to 120°. One patient required amputation above the elbow because of persistent infection and chronic pain after attempted reconstruction with distraction osteogenesis for infected total elbow replacement with humeral bone loss. The average length of follow-up after EA was 33 months (range, 18-60 months). At final follow-up, the median score of the shortened Disabilities of the Arm, Shoulder, and Hand questionnaire was 42.4 (27.3-52.2). Three patients returned to their working activities. Conclusions EA is not a common orthopedic procedure. Despite its difficulties and need of specific training, the Ilizarov technique provides a reproducible and reliable way of achieving solid fusion with the desired angle. Advantages include infection control, early mobilization, accurate application, convertibility and versatility compared with a monolateral fixator, and improved union rate.
Massive segmental tibial bone loss from trauma, tumor, or infection is a limb-threatening situation. It is a considerable surgical challenge, especially when associated with extensive skin and soft ...tissue damage. Amputation was the only solution in the past, but current limb-salvage options include contralateral or ipsilateral microvascularized or free-fibular transfer. However, these methods are not without risks and disadvantages. We report seven patients with massive tibial bone loss treated by gradual medial transport of the ipsilateral fibula using an Ilizarov traction apparatus with olive wires after proximal and distal fibular osteotomies. This method has the advantages of avoiding surgery on the contralateral limb while allowing early weightbearing because of the stability of the Ilizarov frame. Hypertrophy of the transported fibula accompanied by full weightbearing and satisfactory joint motion occurred in all patients. All patients were satisfied with the results, and none thought amputation would have been a better treatment. The minimum followup was 5 years. We think the Ilizarov frame for ipsilateral fibular gradual transport is a reasonable alternative for limb salvage in patients with massive tibial bone loss.

Abstract We retrospectively review 84 cases of diaphyseal humeral fractures (24 type A, 38 type B, 22 type C of the AO/OTA classification) treated with external fixation (Hoffmann II frame) between ...1995 and 2007. Six of these fractures were complicated with radial nerve palsy. Four cases were open fractures. All reductions were achieved closely or through minimal open approaches. All fractures achieved consolidation with an average of 95 days (range 58–140). The six radial nerve palsies had complete spontaneous recovery. According to the Constant score excellent shoulder function was recorded in 54.6% of the cases, good results in 25%, fair in 13.6% and poor in 6.8%. The elbow function according to the Mayo elbow performance index was excellent in 81.8% of cases, good in 13.6%, fair in 2.3%, and poor in 2.3%. We observed superficial pin tract infections in 12% of the patients. There was no cases of deep infection. External fixation of humeral diaphyseal fractures as recorded in this case series, represents a management option, which allows straightforward fracture reduction and adequate stability, with a short operative time, excellent consolidation rate and good functional results with no major complications secondary to this type of surgery.
This article affirms the value of the application of the Ilizarov frame for gradual transport of the ipsilateral fibula to replace massive tibial bone loss following chronic refractory osteomyelitis.
