Abstract
Our objective was to report the use of distraction osteogenesis at the site of angular limb deformity correction using external skeletal fixation for treatment of 1 femoral and 1 tibial angular limb deformity in 2 large-breed puppies. Medical records were reviewed from 2 dogs (a 7-month-old intact male golden retriever and a 4-month-old intact female German shepherd mixed breed) diagnosed with angular limb deformities and truncation of a pelvic limb. Surgical treatment consisted of neutral wedge ostectomy and distraction osteogenesis at the site of bone deformity with an external skeletal fixator (ESF). The surgical technique and postoperative period of distraction osteogenesis were reviewed along with postoperative complications and clinical outcomes after complete bone healing was evident radiographically. Both dogs had adequate bone formation during distraction osteogenesis and the ESFs remained intact and structurally stable. At ESF removal, femoral length had increased 2.6 cm for Dog 1 and tibial length increased 3.88 cm for Dog 2, distal femoral valgus improved 16.3 degrees for Dog 1, and tibial procurvatum improved 19.5 degrees and distal tibial valgus improved 6.2 degrees for Dog 2. At the last follow-up examinations, 5 mo (Dog 1) and 3 mo (Dog 2) postoperatively, both dogs were ambulating without any visible lameness. Key clinical message: Acute angular correction and subsequent distraction osteogenesis at the site of bone deformity and corrective ostectomy using an ESF enabled successful treatment of femoral (Dog 1) and tibial (Dog 2) truncation and angulation in 2 large-breed puppies. Optimal deformity correction and lengthening were achieved through distraction osteogenesis at the site of neutral wedge ostectomy, minimizing soft tissue dissection and risk for potential complications that can occur with bifocal deformity correction (i.e., correction of the deformity at 1 osteotomy/ostectomy and correction of bone length at another, remote osteotomy).

J Clin Orthop Trauma 2023; 44:102255. [PMID: 37817763 PMCID: PMC10561033 DOI: 10.1016/j.jcot.2023.102255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 06/30/2023] [Accepted: 09/21/2023] [Indexed: 10/12/2023] Open
Abstract
Introduction Treatment of infected nonunion of the distal juxta-articular tibia is a challenge due to a short distal fragment, deformity, thin soft-tissue envelope, and active infection. There is still no consensus on the approach that is able to maximally salvage the limb and ankle function. Material and methods Infected juxta-articular nonunion of the distal tibia was managed with two Ilizarov techniques, monofocal compression (MC) used in 12 patients and bifocal compression-distraction (BCD) in 6 patients. The choice of the technique depended on the size of the postresection defect, ≥3 cm or ≤3 cm, respectively. The tactics of functional approach were careful debridement, insertion of wires in the distal fragment so that they do not penetrate the ankle joint, stable fixation, and temporary bridging of the ankle and forefoot. MSCT was used along with regular radiography to assess the union and regeneration. Ankle functions were evaluated with AOFAS ankle-hindfoot score system. Results Bone consolidation, infection arrest and ankle function improvement were achieved in all patients. External fixation continued 221.7 ± 15.1 days for MC and 235 ± 25.8 days for BCD. Complications were wound divergence, wire-tract infection, premature consolidation of the fibula, and hypoplastic regeneration in one case. The mean functional AOFAS score after treatment was 90.7 ± 2.5 points in MC and 89.7 ± 1.3 in BCD patients. Residual limb discrepancy after MC ranged 0-4 cm. Bone shortening was compensated in BCD patients. Conclusion Limb-salvage and functional approach to the treatment of infected nonunion of the juxta-articular distal tibia with the Ilizarov techniques achieves good outcomes. It provides bone infection arrest, consolidation, defect compensation and significantly improves the ankle joint function.

Abstract
Hindfoot and ankle Charcot neuroarthropathy is a challenging condition to treat, specifically with segmental bone defects secondary to avascular necrosis or infection. Several techniques exist alongside continued challenges of nonunion and complication rates. The authors assert that combining distal tibial distraction osteogenesis with external fixation in tibiocalcaneal or tibiotalocalcaneal arthrodesis should be considered an effective method for management of complex Charcot neuroarthropathy conditions of the ankle. This staged procedure technique resulted in a high rate of union in patients who are often considered a high risk for nonunion, as well as eradication of infection, minimal soft tissue disruption, and improvement in limb length.

Abstract
Charcot neuroarthropathy of the hindfoot and ankle poses substantial challenges due to deformity, segmental bone loss, chronic infection, and difficulty with bracing. Hindfoot or ankle arthrodesis is often employed at high rates of complications and nonunion. This study reports 15 consecutive patients with Charcot neuroarthropathy who underwent tibiotalocalcaneal or tibiocalcaneal fusion with simultaneous distal tibial distraction osteogenesis with a mean follow-up period of 20.2 ± 5.66 months. Arthrodesis rate was 93.3% (14 patients) with mean time to fusion of 4.75 ± 3.4 months. One hypertrophic nonunion occurred at the arthrodesis site. Complete consolidation of 4 cortices was achieved at the distraction site in 93.3% of patients (14 patients) with a mean duration to consolidation of 9.8 ± 3.3 months. One patient experienced hypertrophic nonunion at the regeneration site. The authors report a technique to enhance arthrodesis rates in Charcot neuroarthropathy by combining distal tibial distraction osteogenesis with simultaneous tibiotalocalcaneal or tibiocalcaneal arthrodesis for hindfoot fusion and salvage. Distraction osteogenesis supports enhanced vascularity to the arthrodesis site.Level of Clinical Evidence: Level 4.

Abstract
Large osseous defects of the hindfoot and ankle pose a surgical challenge. Tibiotalocalcaneal (TTC) arthrodesis utilizing a structural allograft may be required to fill the osseous void, preserve limb length and achieve fusion. Several authors have reported small case series on this topic, however outcomes have varied and no systematic review of this data has been published to date. The primary aim of this study is to report rates of osseous union, limb salvage and complications in patients undergoing TTC arthrodesis with a structural allograft. A total of 11 publications were identified that met the inclusion criteria. One hundred seventy-five patients were included with a weighted mean age of 60.5 (range 50-72) years and follow-up period of 29.7 (range 3-62) months. Femoral head allograft was the most commonly utilized structural graft and a retrograde intramedullary nail was the most common fixation construct. Results demonstrated an overall union rate of 67.4%, limb salvage rate of 92.5% and complication rate of 26.6%. Allograft-related complications were rare with an allograft fracture rate of 0.1% and allograft collapse rate of 1.2%. There was no significant difference in union rate when using a retrograde intramedullary nail versus a plate construct (p = .9148). TTC arthrodesis with use of a structural allograft is a viable treatment option for limb salvage when faced with complex hindfoot and ankle pathology involving large osseous defects. Despite high rates of radiographic nonunion, this approach can provide patients with a stable and functional limb while avoiding amputation.

Abstract
Background. The use of circular external fixation is a fundamental necessity in the armamentarium of a lower limb orthoplastic reconstructive surgeon. External fixation offers orthoplastic surgeons the ability to address soft tissue and osseous defects simultaneously. Using Ilizarov principles, the reconstructive surgeon must have the ability to address unique scenarios when performing orthoplastic principles. This article offers practical surgical management concepts based on experience using the TL-Hex Orthofix Truelok Hexapod System for acute shortening and relengthening. A soft tissue and osseous defect can be managed through this surgical approach as a limb salvage alternative to amputation. The information provided will lead to improved management strategies and outcomes for the practitioner and patient when presented with soft tissue and osseous defects.

Abstract
Osteoarticular infections are challenging and difficult to treat. The use of innovative technologies like 3D printing already employed in other types of surgeries and pathologies can suppose a great asset to tackle the problem and improve functional results. We present a case of an osteoarticular infection of an ankle treated with a custom-made titanium talus made with 3D metal printing technology: A 63-year-old patient, with chronic infection of the ankle. A 2-staged surgery was performed, with a hand-made cement spacer used during the first stage and the implantation of a custom-made titanium talus with an arthrodesis nail in the second stage. After a 2-year follow-up, a good clinical evolution was achieved, with no signs of reactivation of the infection, no pain, good skin condition and optimal functionality: functional gait pattern without pain and any external aids.

Abstract
Aims Distraction osteogenesis (DO) is a useful orthopaedic procedure employed to lengthen and reshape bones by stimulating bone formation through controlled slow stretching force. Despite its promising applications, difficulties are still encountered. Our previous study demonstrated that pulsed electromagnetic field (PEMF) treatment significantly enhances bone mineralization and neovascularization, suggesting its potential application. The current study compared a new, high slew rate (HSR) PEMF signal, with different treatment durations, with the standard Food and Drug Administration (FDA)-approved signal, to determine if HSR PEMF is a better alternative for bone formation augmentation. Methods The effects of a HSR PEMF signal with three daily treatment durations (0.5, one, and three hours/day) were investigated in an established rat DO model with comparison of an FDA-approved classic signal (three hrs/day). PEMF treatments were applied to the rats daily for 35 days, starting from the distraction phase until termination. Radiography, micro-CT (μCT), biomechanical tests, and histological examinations were employed to evaluate the quality of bone formation. Results All rats tolerated the treatment well and no obvious adverse effects were found. By comparison, the HSR signal (three hrs/day) treatment group achieved the best healing outcome, in that endochondral ossification and bone consolidation were enhanced. In addition, HSR signal treatment (one one hr/day) had similar effects to treatment using the classic signal (three three hrs/day), indicating that treatment duration could be significantly shortened with the HSR signal. Conclusion HSR signal may significantly enhance bone formation and shorten daily treatment duration in DO, making it a potential candidate for a new clinical protocol for patients undergoing DO treatments.

Abstract
The Ilizarov method is one of the current methods used in bone reconstruction. It originated in the middle of the past century and comprises a number of bone reconstruction techniques executed with a ring external fixator developed by Ilizarov GA. Its main merits are viable new bone formation through distraction osteogenesis, high union rates and functional use of the limb throughout the course of treatment. The study of the phenomenon of distraction osteogenesis induced by tension stress with the Ilizarov apparatus was the impetus for advancement in bone reconstruction surgery. Since then, the original method has been used along with a number of its modifications developed due to emergence of new fixation devices and techniques of their application such as hexapod external fixators and motorized intramedullary lengthening nails. They gave rise to a relatively new orthopedic subspecialty termed “limb lengthening and reconstruction surgery”. Based on a comprehensive literature search, we summarized the recent clinical practice and research in bone reconstruction by the Ilizarov method with a special focus on its modification and recognition by the world orthopedic community. The international influence of the Ilizarov method was reviewed in regard to the origin country of the authors and journal’s rating. The Ilizarov method and other techniques based on distraction osteogenesis have been used in many countries and on all populated continents. It proves its international significance and confirms the greatest contribution of Ilizarov GA to bone reconstruction surgery.

Abstract
We present a case of a 13-year-old female with severe varus deformity and limb discrepancy resulting from epiphyseal fracture. The preoperative tibial articular surface angle was 64.1°, and the affected tibia was 14 mm shorter than the contralateral tibia. She underwent a medial open osteotomy and fibular osteotomy with gradual distraction correction using Ilizarov fixator. The deformity was corrected at 3 months, and the external fixator was removed when bony union was achieved 6 months postoperatively. At 9 months after surgery, the patient could play basketball without feeling pain. At the last follow-up, namely 36 months after the operation, the American Orthopaedic Foot and Ankle Society hindfoot-ankle score was improved from 58 to 90, the patient was pain free, and the radiological measurements were nearly normal. Ilizarov fixator gradual distraction correction for distal tibial severe varus deformity is a safe and cost-effective method that can yield excellent radiological and clinical outcomes.

Abstract
PURPOSE Treatment of irreducible femoral intertrochanteric fractures often requires open reduction. However, the technique unavoidably causes patients to suffer greater trauma. As such, minimally invasive techniques should be employed to reduce the surgical-related trauma on these patients and maintain a stable reduction of the fractures. Herein, a minimally invasive wire introducer was designed and used for the treatment of femoral intertrochanteric fractures. The effectiveness of using a wire-guided device to treat irreducible femoral intertrochanteric fractures was evaluated. METHODS Between 2013 and 2018, patients with femoral intertrochanteric fractures who were initially treated by intramedullary nail fixation but had difficult reduction using the traction beds were retrospectively reviewed. Decision for an additional surgery was based on the displacement of the fracture. The patients were then divided into two groups: those in the control group received an open reduction surgery while those in the observation group received a closed reduction surgery using a minimally invasive wire introducer to guide the wire that could assist in fracture reduction. The operation time, blood loss, visual analogue scale scores, angulation, reduction, neck-shaft angle, re-displacement, limb length discrepancy, and union time were then recorded and analyzed to determine the efficiency of the wire introducer technique. Categorical variables were analyzed by using Chi-square test, while continuous variables by independent t-test and the Mann-Whitney test accordingly. RESULTS There were 92 patients included in this study: 61 in the control group and 31 in the observation group. There were no significant differences in baseline demographic factors between the two groups. All surgeries were successful with no deaths within the perioperative period. The average follow-up time for the patients was 23.8 months. However, the observation group had a significantly shorter operation time, lower visual analogue scale score, less intraoperative bleeding, and shorter fracture healing time. There were no significant differences in the angulation, reduction, neck-shaft angle, and limb length discrepancy between the two groups. CONCLUSION The minimally invasive wire guide achieved a similar effect to that of open reduction in the treatment of intertrochanteric fractures with difficult reduction. Moreover, the minimally invasive wire introducer is a good technology that accurately guides the wire during reduction. Indeed, it is an effective technique and achieves good clinical outcomes in restoration of irreducible femoral intertrochanteric fractures.

Abstract
Background and purpose - Motorized intramedullary lengthening nails (ILNs) have been developed as an alternative to external fixators for long bone lengthening. The antegrade approach represents the standard method for tibial ILN insertion. In patients with preexisting ankle and hindfoot fusion a retrograde approach provides an alternative technique that has not been evaluated so far. We report the outcome of this method in 10 patients. Patients and methods - This retrospective study included 10 patients (mean age 18 years [13-25]) with preexisting ankle and hindfoot fusion who underwent tibial lengthening with a retrograde ILN (PRECICE). The mean leg length discrepancy (LLD) was 58 mm (36-80). The underlying conditions were congenital (n = 9) and post tumor resection (n = 1). The main outcome measures were: ILN reliability, distraction achieved, distraction index (DIX), time to bone healing, consolidation index (CIX), complications, and functional results. Results - All patients achieved the goal of lengthening (mean 48 mm [26-80]). Average DIX was 0.6 mm/day (0.5-0.7) and mean CIX was 44 days/cm (26-60). Delayed consolidation occurred in 2 patients and healed after ILN dynamization or nail exchange with grafting. Toe contractures in 2 other patients were resolved with physiotherapy or tenotomy. Until last follow-up (mean 18 months [12-30]) no true complications were encountered, knee motion remained unaffected, and full osseous consolidation occurred in all patients. Interpretation - In patients with LLD and preexisting ankle and hindfoot fusion distal tibial lengthening using a retrograde ILN is a reliable alternative to the standard approach with equivalent bone healing potential and low complication rates leaving the knee unaffected.

Abstract
Revision surgery for failed total ankle replacement is a challenge to the revision surgeon. Deformity, presence of infection, segmental bone defects, patient comorbidities, and soft tissue compromise all are significant considerations when determining appropriate procedures. Revision total ankle replacement, explant and fusion with or without lengthening, use of a trabecular metal cage, placement of an antibiotic cement spacer, grafting, and amputation all are viable options to treat patients with failed ankle arthroplasty.
