Assessment of the distribution of load on the lower limbs and balance before and after ankle arthrodesis with the Ilizarov method. Sci Rep 2018; 8:15693. [PMID: 30356110 PMCID: PMC6200736 DOI: 10.1038/s41598-018-34016-3] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2018] [Accepted: 10/06/2018] [Indexed: 01/03/2023] Open
Abstract
Ankle arthrodesis with the Ilizarov method is an accepted form of treatment of advanced degenerative changes of the ankle joint. Incorrect balance and load distribution on the lower limbs may result in pain and dysfunction. The aim of the study was to assess the change of balance and load distribution in lower extremities in patients before and after ankle arthrodesis with the Ilizarov method. Between 2013 and 2016, ankle arthrodesis using the Ilizarov method was performed on 21 patients. The evaluation of balance and percentage of load in each lower limb was performed before the surgery and during the follow-ups. The evaluation was performed using a Zebris pedobarographic platform. Before the surgery, the patients exhibited an average load of 41.9% of body weight in the affected limb, whereas the load in the healthy limb was 58.1%. The difference was statistically significant (p = 0,000031). In two years follow-up, the average load in the treated limbs was 48.19%, whereas the healthy limbs were subjected to an average load of 51.81%. In preoperative tests, the average path length of the center of gravity was 161.55 cm; postoperatively, the average path length of the center of gravity was 129.7 cm (p = 0.00003206). Preoperatively, the average area of the center of gravity was 18.85 cm2; it decreased to 6.19 cm2 (p = 0.000032) postoperatively. Arthrodesis of the ankle with the Ilizarov method improved the statics of the musculoskeletal system by improving the distribution of loads in the lower limbs as well as balance. However, it failed to restore the parameters of a healthy person. Advanced degenerative changes of the ankle disturb the biomechanics of the entire lower limb.

Abstract
BACKGROUND Nonunions of the distal tibia in close proximity to the ankle joint can be a challenge to treat. The purpose of this study was to evaluate radiographic and clinical outcomes of patients who underwent ankle-sparing bone transport for periarticular distal tibial nonunions. METHODS Twenty-one patients underwent ankle-sparing bone transport between January 2006 and July 2016. The mean age of the patients was 48.6 years, and 71% (15/21) were male. Patients were followed for an average of 14.6 months (range, 10.6-17.7 months), with an average of 8.6 months in-frame. Thirteen of 21 patients had infected nonunions. Primary endpoints included time to union and American Orthopaedic Foot & Ankle Society (AOFAS) score. RESULTS All fractures achieved union. Mean time to union was 37.4 weeks. Mean AOFAS score was 86.3 points (range, 37-100). A score of 37 was observed in 1 patient with preexisting Charcot foot. Radiographic evaluation at 6 months revealed a mean lateral distal tibial angle of 89.2 degrees and a mean anterior distal tibial angle of 76 degrees. Leg length discrepancy was less than 1.2 cm in all patients. Superficial pin infection was observed in 7 patients, and operative wound infection at the level of bone resection was observed in 3 patients. CONCLUSION The ankle-sparing bone transport technique was an effective alternative to bone graft and arthrodesis for the treatment of periarticular nonunions of the distal tibia and was safe for use in patients with infected nonunions in close proximity to the ankle joint.

Abstract
Aims The aim of this study was to describe the technique of distraction osteogenesis followed by arthrodesis using internal fixation to manage complex conditions of the ankle, and to present the results of this technique. Patients and Methods Between 2008 and 2014, distraction osteogenesis followed by arthrodesis using internal fixation was performed in 12 patients with complex conditions of the ankle due to trauma or infection. There were eight men and four women: their mean age was 35 years (23 to 51) at the time of surgery. Bone healing and functional recovery were evaluated according to the criteria described by Paley. Function was assessed using the ankle-hindfoot scale of the American Orthopedic Foot and Ankle Society (AOFAS). Results A solid fusion of the ankle and eradication of infection was achieved in all patients. A mean lengthening of 6.1 cm (2.5 to 14) was achieved at a mean follow-up of 25.2 months (14 to 37). The mean external fixation index (EFI) was 42 days/cm (33.3 to 58). The function was judged to be excellent in six patients and good in six patients. Bone results were graded as excellent in ten patients and good in two patients. The mean AOFAS score was 37.3 (5 to 77) preoperatively and 75.3 (61 to 82) at the final follow-up. Minor complications, which were treated conservatively, included pain, pin-tract infection, loosening of wires, and midfoot stiffness. Major complications, which were treated surgically included grade V pin-tract infection with inflammation and osteolysis, poor consolidation of the regenerate bone, and soft-tissue invagination. The reoperations required to treat the major complications included the exchange of pins and wires, bone grafting and invagination split surgery. Conclusion The technique of distraction osteogenesis followed by arthrodesis using internal fixation is an effective form of treatment for the management of complex conditions of the ankle. It offers a high rate of union, an opportunity to remove the frame early, and a reduced EFI without infection or wound dehiscence. Cite this article: Bone Joint J 2018;100-B:755–60.

Abstract
INTRODUCTION Charcot's neuroarthropathy of ankle leads to instability, destruction of the joint with significant morbidity that may require an amputation. Aim of surgical treatment is to achieve painless stable plantigrade foot through arthrodesis. Achieving surgical arthrodesis in Charcot's neuroarthropathy has a high failure rate. We assess the outcomes of retrograde intramedullary interlocked nailing in tibio-talar arthrodesis for Charcot's neuroarthropathy. MATERIALS AND METHODS 42 diabetic patients with a mean age of 49 year underwent ankle tibio-talar arthrodesis using retrograde nailing for Charcot's neuroarthropathy. The postoperative complications have been discussed and their management outlined. The outcomes were measured radiologically and clinically. Follow up was done after 6 weeks, 3 months, 6 months and 1 year. RESULTS 14 patients (33.3%) achieved uneventful uncomplicated fusion. Thirty three patients had varus deformity. Nine patients had valgus deformity. Using Paired t test, it showed statistically significant improvement in the functional outcomes (AOFAS& EQ-5D-5L) over the follow up time, despite of the mild deterioration of radiological angles in the final follow up visit compared to the postoperative radiological findings. CONCLUSION Retrograde nailing is one of the best options for tibio-talo-calcaneal arthrodesis in the high-risk Charcot's neuroarthropathy population. It could be done through small incisions with lower soft tissue complications, its load-sharing properties allows a considerable compression across the ankle and talocalcaneal joints with early weight bearing and with satisfactory functional outcomes.

Abstract
BACKGROUND Ankle fusion is difficult to achieve in the diabetic Charcot ankle Brodsky type 3a because of the poor quality of the bone and the inability to achieve a stable biomechanical construct. The aim of this study was to report the outcome of ankle fusion using a combination of an intramedullary nail and a circular external fixator in patients with diabetic Charcot arthropathy. METHODS We prospectively studied 24 patients with diabetic Charcot arthropathy of the ankle who were treated by fusion of the tibiotalar joint using a combined retrograde intramedullary nail and Ilizarov external fixator. Their mean age was 50.7 ± 6.9 (range, 43-62) years. The mean follow-up after surgery was 36.4 ± 5.8 (range, 24-98) months. RESULTS Twenty-two patients (92%) achieved clinical and radiographic solid bony fusion. No patients in this series needed amputation. All the patients were pain free, and the mean American Orthopaedic Foot & Ankle Society Score (AOFAS) improved significantly from 34.6 ± 6.8 to 66.4 ± 4.5 at the last follow-up. Two patients developed an ulcer over the heel due to a prominent nail. The ulcer healed after nail removal. Eight patients developed pin tract infection. CONCLUSION We report a successful outcomes of ankle fusions using combined intramedullary nail locked only proximally and ring external fixator (hybrid fixation) in patients with diabetic Charcot arthropathy.

Abstract
The purpose of this study was to evaluate the effect of Ilizarov external fixation (IEF) and plate internal fixation (PIF) in the treatment of end-stage ankle arthritis on pain relieving and function improvement. The study cohort consisted of 59 patients with end-stage ankle arthritis underwent ankle arthrodesis with IEF or PIF between June 2011 and June 2015. Standard radiographs and computed tomography (CT) scans were obtained before surgery and during the follow-up. Functional assessments were performed using Foot and Ankle pain score of American Orthopedics Foot and Ankle Society (AOFAS) and Visual Analogue Scale (VAS). The average AOFAS scores in both IEF group and PIF groups increased significantly after operation, from 45.5 ± 6.3 to 84.8 ± 4.9 and from 45.9 ± 6.6 to 86.6 ± 5.4, respectively. The average VAS scores in both groups decreased significantly after operation, from 8.4 ± 1.9 to 2.5 ± 0.6 and from 8.2 ± 1.5 to 2.3 ± 0.7, respectively. Nevertheless, there was no significant difference for preoperative or postoperative AOFAS and VAS scores between the two groups. The IEF would result in comparable postoperative functional recovery and pain relieving to PIF and may be an effective substitute to PIF in the treatment of end-stage ankle arthritis.

Abstract
INTRODUCTION We asked whether the type of ankle joint arthrodesis stabilization will affect: (1) rate of union, (2) rate of adjacted-joint arthritis, (3) malalignment of the ankle joint. MATERIAL AND METHODS We retrospectively radiological studied 62 patients who underwent ankle arthrodesis with Ilizarov external fixator stabilization (group 1,n=29) or internal stabilization (group 2,n=33) from 2006 to 2015. Radiologic outcomes were mesure by: (1) rate of union, (2) rate of adjacent-joint arthritis, (3) malalignment of the ankle joint. The Levene's test,Mann-Whitney U test and Students t-test were used to the statistical analyses. RESULTS Ankle fusion was achieved in 100% of patients treated with external fixation and in 88% with internal stabilization. Desired frontal plane alignment was achieved in 100% of patients with external fixation and 76% with internal stabilization. Desired sagittal plane alignment was achieved in 100% of external fixation and 85% of internal stabilization. A total of 14 (48.3%) patients from group 1 showed a radiographic evidence of pre-existing adjacent-joint OA. The radiographic evidence of pre-existing adjacent-joint OA was also found in 27(81.8%) subjects from group 2. Alterations of adjacent joints were also found on postoperative radiograms of 19 (65.5%) patients subjected to Ilizarov fixation and in all 33 patients from group 2. DISCUSION Ilizarov fixation of ankle arthrodesis is associated with lower prevalence of adjacent-joint OA and ankle joint misalignment,and with higher fusion rates than after internal fixation.Although achieving a complex ankle fusion is generally challenging,radiological outcomes after fixation with the Ilizarov apparatus are better than after internal stabilization.

Abstract
BACKGROUND Pin infection continues to be a nuisance when using definitive external fixation. Prophylactic antibiotic treatment has been proposed in an effort to decrease pin complications. QUESTIONS/PURPOSES We performed a prospective, randomized, single-blinded study to answer the following questions: (1) what was the effect of a 10-day course of oral prophylactic antibiotics administered immediately after external fixation surgery on the incidence of a subsequent pin infection, (2) what was the effect on the severity of a subsequent pin infection, and (3) what was the effect on the timing of a subsequent pin infection? METHODS Patients were randomized into antibiotic treatment and control groups, and incidence, severity, and time of onset of pin infection were recorded. RESULTS The incidence of pin infection for the entire cohort during the 90-day observation period was 46/58 (79%) without a statistically significant difference (p = 0.106). There was no statistical difference found (p = 0.512) in pin infection severity. There was no significant difference in the time of onset of infection between the two groups from the date of surgery (p = 0.553). CONCLUSIONS Our randomized data do not suggest that oral antibiotics alter the incidence, timing, or severity of pin infection. This study does not support the use of prophylactic oral antibiotics in healthy patients.

Abstract
Although numerous studies have linked smoking with lower extremity wound and bone healing complications, a comprehensive study on the effects of smoking in foot and ankle surgery has not yet been reported. The purpose of the present study was to report the results of our systemic literature review, identifying the effects of tobacco use on common foot and ankle procedures. The systematic literature review was performed according to guidelines set by the PRIMSA statement (Preferred Reporting Items for Systematic Review and Meta-Analyses). Smoking, as a single risk factor, was analyzed and used to compare adverse outcomes in the postoperative setting of foot and ankle surgery. We reviewed 528 abstracts that met our initial identification criteria. After an extensive review process, 46 of the articles (8.71%) met the eligibility requirements to be included in the present study. Distal bunionectomy with osteotomy, first metatarsophalangeal joint arthrodesis, Lapidus bunionectomy, toe amputation, transmetatarsal amputation, Syme's amputation, open reduction internal fixation (ORIF) of calcaneal fractures, ankle fracture ORIF, pilon fracture ORIF, subtalar arthrodesis, rearfoot arthrodesis, tibiocalcaneal arthrodesis, ankle arthrodesis, total ankle arthroplasty, and plastic surgery procedures and their respective negative association with smoking was identified and described in our review. Our systematic literature review revealed that procedures involving arthrodesis, fracture ORIF, and plastic surgery were associated with negative outcomes in smokers. Procedures that did not involve osseous unions such as total ankle arthroplasty and amputations did not appear to have negative outcomes associated with smoking.

Abstract
Posttraumatic infection of the foot and ankle is a challenging issue for orthopedic surgeons. Making the diagnosis often requires combining laboratory and radiologic testing, patient examination, and history. Patient comorbidities should be identified and optimized whenever possible. Treatment must combine effective antibiotic therapy with thorough debridement of the infected zone. Reconstruction often requires a 2-staged approach using antibiotic spacers and temporary external fixation, with the goal of obtaining a functional, pain-free limb that is free of infection.

Abstract
BACKGROUND Surgical strategies to address deformities of the ankle and hindfoot in patients with Charcot arthropathy include the use of retrograde intramedullary nails and ring fixators. The literature has not shown superiority of one technique over the other. This study presents a single surgeon's case series of Charcot arthropathy patients treated with either a ring fixator or retrograde intramedullary nail to achieve tibiotalocalcaneal arthrodesis. METHODS We performed a retrospective analysis of 27 consecutive patients with Charcot arthropathy who underwent a tibiotalocalcaneal arthrodesis using either a retrograde intramedullary (IM) nail (n = 16 patients) or a ring fixator (RF) (n = 11 patients) by a single surgeon. We report the rates of limb salvage complications requiring secondary surgery and fusion in both groups. The patient demographics and presence of medical comorbidities known to increase the risk of surgical complications were similar between groups. The mean duration of follow-up for the retrograde nail group was 3.6 years and 2.2 years for the ring fixator group. RESULTS The mean time to discharge from the hospital after the index surgical procedure was 2.7 days for the IM group and 4.6 days for the RF group. For the patients treated with a ring fixator, the mean time to removal of the frame after the initial application was 13.3 ± 1.8 weeks. The limb salvage rate for the RF group was 9 of 11 patients whereas it was 15 of 16 in the IM group. Complications including deep infection, hardware failure, and symptomatic nonunion requiring revision surgery were common in the IM group, with 11 of 16 patients requiring further surgery. Seven patients in the IM group required removal of the implant at a mean of 117.2 weeks after the index procedure because of the development of deep infection or nail cutout. In the RF group, only 1 patient required revision surgery. Fusion rates were similar between both groups, with 10 of 16 patients fusing in the IM group and 7 of 11 in the RF group. CONCLUSION Use of a retrograde intramedullary rod or ring fixator resulted in high rates of successful limb salvage when used for tibiotalocalcaneal arthrodesis in patients with Charcot arthropathy. However, in this study, the need for revision surgery was more frequent in the retrograde nail group compared to the ring fixator group. LEVEL OF EVIDENCE Level III, retrospective comparative series.

Abstract
OBJECTIVES Systematic review and meta-analysis of published observational cohort studies. To quantify the increased risk smokers have of experiencing a delayed and/or non-union in fractures, spinal fusion, osteotomy, arthrodesis or established non-unions. SETTING Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica database (EMBASE), Allied and Complementary Medicine Database (AMED) and Web of Science Core Collection from 1966 to 2015. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND INTERVENTIONS Observational cohort studies that reported adult smokers and non-smokers with delayed and/or non-union or time to union of the fracture, spinal fusion, osteotomy, arthrodesis or established non-union were eligible. DATA EXTRACTION AND OUTCOME MEASURES 2 authors screen titles, abstracts and full papers. Data were extracted by 1 author and checked independently by a second. The relative risk ratios of smoking versus non-smoking and the mean difference in time to union patients developing a delayed and/or non-union were calculated. RESULTS The search identified 3013 articles; of which, 40 studies were included. The meta-analysis of 7516 procedures revealed that smoking is linked to an increased risk of delayed and/or non-union. When considered collectively, smokers have 2.2 (1.9 to 2.6) times the risk of experiencing delayed and/or non-union. In all the subgroups, the increased risk was always ≥1.6 times that of non-smokers. In the patients where union did occur, it was a longer process in the smokers. The data from 923 procedures were included and revealed an increase in time to union of 27.7 days (14.2 to 41.3). CONCLUSIONS Smokers have twice the risk of experiencing a non-union after fracture, spinal fusion, osteotomy, arthrodesis or treatment of non-union. Time to union following fracture, osteotomy, arthrodesis or treatment of an established non-union is longer in smokers. Smokers should be encouraged to abstain from smoking to improve the outcome of these orthopaedic treatments.

Abstract
OBJECTIVES Systematic review and meta-analysis of published observational cohort studies. To quantify the increased risk smokers have of experiencing a delayed and/or non-union in fractures, spinal fusion, osteotomy, arthrodesis or established non-unions. SETTING Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica database (EMBASE), Allied and Complementary Medicine Database (AMED) and Web of Science Core Collection from 1966 to 2015. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND INTERVENTIONS Observational cohort studies that reported adult smokers and non-smokers with delayed and/or non-union or time to union of the fracture, spinal fusion, osteotomy, arthrodesis or established non-union were eligible. DATA EXTRACTION AND OUTCOME MEASURES 2 authors screen titles, abstracts and full papers. Data were extracted by 1 author and checked independently by a second. The relative risk ratios of smoking versus non-smoking and the mean difference in time to union patients developing a delayed and/or non-union were calculated. RESULTS The search identified 3013 articles; of which, 40 studies were included. The meta-analysis of 7516 procedures revealed that smoking is linked to an increased risk of delayed and/or non-union. When considered collectively, smokers have 2.2 (1.9 to 2.6) times the risk of experiencing delayed and/or non-union.

Abstract
End-stage arthritis of the tibiotalar joint is disabling and causes substantial functional impairment. Most often it is the residual effect of a previous traumatic injury. Nonsurgical treatment of end-stage arthritis of the ankle includes bracing, shoe-wear modifications, and selective joint injections. For patients who fail to respond to nonsurgical modalities, the two primary treatment options are arthroplasty and arthrodesis. Each has its proponents. Although no ideal treatment of ankle arthritis exists, high-quality studies can help guide treatment in patients of varying demographics. Inherent risks are linked with each treatment option, but those of greatest concern are early implant loosening that requires revision following arthroplasty and the acceleration of adjacent joint degeneration associated with arthrodesis.

Abstract
Charcot neuroarthropathy (CN) of the foot and ankle is a demanding clinical dilemma, and surgical management can be very complicated. Historically, the evidence guiding surgical management of CN has been small retrospective case series and expert opinions. The purpose of the present report was to provide a systematic review of studies published from 2009 to 2014 and to review the indications for surgery. A Medline search was performed, and a systematic review of studies discussing the surgical management of CN was undertaken. Thirty reports fit the inclusion criteria for our study, including 860 patients who had undergone a surgical procedure for the treatment of CN. The surgical procedures included amputation, arthrodesis, debridement of ulcers, drainage of infections, and exostectomy. The midfoot was addressed in 26.9% of cases, the hindfoot in 41.6%, and the ankle in 38.4%. Of the 30 studies, 24 were retrospective case series (level 4), 4 were controlled retrospective studies (level 3), and 2 were level II studies. The overall amputation rate was 8.9%. The quality of the published data on the surgical management of CN has improved during the past several years. Evidence concerning the timing of treatment and the use of different fixation methods remains inconclusive.

Abstract
Complex ankle arthrodesis is defined as an ankle fusion that is at high risk of delayed and nonunion secondary to patient comorbidities and/or local ankle/hindfoot factors. Risk factors that contribute to defining this group of patients can be divided into systemic factors and local factors pertaining to co-existing ankle or hindfoot pathology. Orthopaedic surgeons should be aware of these risk factors and their association with patients' outcomes after complex ankle fusions. Both external and internal fixations have demonstrated positive outcomes with regards to achieving stable fixation and minimizing infection. Recent innovations in the application of biophysical agents and devices have shown promising results as adjuncts for healing. Both osteoconductive and osteoinductive agents have been effectively utilized as biological adjuncts for bone healing with low complication rates. Devices such as pulsed electromagnetic field bone stimulators, internal direct current stimulators and low-intensity pulsed ultrasound bone stimulators have been associated with faster bone healing and improved outcomes scores when compared with controls. The aim of this review article is to present a comprehensive approach to the management of complex ankle fusions, including the use of biophysical adjuncts for healing and a proposed algorithm for their treatment.

Abstract
We report the outcomes of 20 patients (12 men, 8 women, 21 feet) with Charcot neuro-arthropathy who underwent correction of deformities of the ankle and hindfoot using retrograde intramedullary nail arthrodesis. The mean age of the patients was 62.6 years (46 to 83); their mean BMI was 32.7 (15 to 47) and their median American Society of Anaesthetists score was 3 (2 to 4). All presented with severe deformities and 15 had chronic ulceration. All were treated with reconstructive surgery and seven underwent simultaneous midfoot fusion using a bolt, locking plate or a combination of both. At a mean follow-up of 26 months (8 to 54), limb salvage was achieved in all patients and 12 patients (80%) with ulceration achieved healing and all but one patient regained independent mobilisation. There was failure of fixation with a broken nail requiring revision surgery in one patient. Migration of distal locking screws occurred only when standard screws had been used but not with hydroxyapatite-coated screws. The mean American Academy of Orthopaedic Surgeons Foot and Ankle (AAOS-FAO) score improved from 50.7 (17 to 88) to 65.2 (22 to 88), (p = 0.015). The mean Short Form (SF)-36 Health Survey Physical Component Score improved from 25.2 (16.4 to 42.8) to 29.8 (17.7 to 44.2), (p = 0.003) and the mean Euroqol EQ‑5D‑5L score improved from 0.63 (0.51 to 0.78) to 0.67 (0.57 to 0.84), (p = 0.012). Single-stage correction of deformity using an intramedullary hindfoot arthrodesis nail is a good form of treatment for patients with severe Charcot hindfoot deformity, ulceration and instability provided a multidisciplinary care plan is delivered.

Abstract
BACKGROUND Although its FDA-approved applications are limited, the pro-osteogenic benefits of recombinant human BMP-2 (rhBMP-2) administration have been shown in off-label surgical applications. However, the effects of rhBMP-2 on ankle fusions are insufficiently addressed in the literature, which fails to include a case-control study of adequate sample size to evaluate the efficacy of rhBMP-2 treatment. QUESTIONS/PURPOSES In this study we asked whether rhBMP-2 treatment (1) would increase the rate of successful ankle fusion in complex patients (patients with comorbidities associated with poor surgical healing) compared with a control group of patients undergoing ankle fusion who did not receive rhBMP-2; (2) would reduce total time wearing a frame when compared with the control group; (3) would result in a difference in the percentage of bone bridging between the group treated with rhBMP-2 and the control group, as determined by CT scans 3 months after surgery; and (4) would encounter an equal rate of complications different from untreated patients. METHODS A retrospective chart study was performed on 82 patients who, because of a host of comorbidities associated with poor healing, required a complex ankle arthrodesis with the Ilizarov technique. The first 40 patients did not receive rhBMP-2, whereas the subsequent 42 patients received intraoperative rhBMP-2. Time wearing the frame was determined by chart review; decision to remove the frame was made by the surgeon based on quantitative bone bridging measured using a CT scan taken 3 months after fusion. RESULTS Patients treated with rhBMP-2 were more likely to obtain fusion after the initial surgery (93% versus 53%, p < 0.001; OR, 11.76; 95% CI, 3.12-44.41), spent less total time wearing the frame (124 versus 161 days, p < 0.01), and showed more bone bridging on CT scans (48% versus 32%, p < 0.05). All patients with greater than 30% bone bridging observed on CT scans 3 months postoperatively achieved successful union without further intervention. CONCLUSIONS Our findings suggest that rhBMP-2 is a beneficial adjunct for selected groups of patients undergoing complex ankle arthrodesis. CT is a promising modality in the assessment of bone healing in ankle fusion. A proper randomized controlled trial remains necessary to fully describe the efficacy of rhBMP-2 in accelerating bone healing.
