Tibiotalocalcaneal arthrodesis using a retrograde intramedullary nail with a valgus curve.

ABSTRACT: OBJECTIVE:Many different techniques have been described for performing tibiotalocalcaneal arthrodesis (TTCA) in patients with severe hindfoot disorders such as failed ankle arthroplasty and failed ankle joint arthrodesis with subsequent subtalar arthritis. The use of straight retrograde intramedullary nails is extremely limited because they may interfere with normal heel valgus position and risk damaging the lateral plantar neurovascular structures. Curved retrograde intramedullary nails have been designed to overcome these shortcomings. The purpose of this single surgeon series was to investigate the outcomes of TTCA using a curved retrograde intramedullary nail. METHODS:From June 2009 to January 2012, 22 patients underwent TTCA using intramedullary nails with a valgus curve by the same senior surgeon. All patients were available for analysis, the mean follow-up being 22.3 months (range, 6.8-38 months). The main outcome measurements included EQ-5D functional scores, the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scale, radiologic assessment and clinical examination. RESULTS:Bony union and a plantigrade foot were achieved in 100% of subjects, the mean time to union being 3.9 months (range, 2.4 to 6.2 months). Structural bone graft was used in all patients. Postoperative radiologic results showed a good hindfoot alignment in all patients. The only complication was one case of delayed wound healing without deep infection. The mean postoperative EQ-5D functional and AOFAS ankle-hindfoot scores were 69.33 (range, 20 to 90) and 69.9 (range, 45 to 85) points, respectively. No revision surgery was necessary in our cohort. CONCLUSION:The results of the present study indicate that TTCA using a short, retrograde, curved intramedullary nail is an acceptable technique for obtaining solid fusion and good hindfoot alignment inpatients with severe hindfoot disorders.

Project description:BackgroundTibiotalocalcaneal (TTC) intramedullary nailing has been suggested as an alternative to open reduction and internal fixation (ORIF) for the primary treatment of unstable fragility ankle fractures with a poor soft tissue envelope. This study aims to investigate the clinical efficacy of TTC intramedullary nail fixation for the primary treatment of unstable ankle fractures in frail elderly patients with poor soft tissue condition, by assessing the number of postoperative complications and the patient-reported functional outcomes.MethodsA retrospective cohort study was performed including patients with an unstable ankle fracture treated between 2015 and 2019 with TTC stabilization using a retrograde intramedullary hindfoot nail that was inserted without joint preparation and allowing immediate weight-bearing postoperatively. The primary outcome was the total number of postoperative complications.ResultsA total of 10 patients were included out of 365 operatively treated ankle fractures. The mean age was 85.2 years (range 66-92) with a mean follow-up of 11.2 months (range 6-16). Fracture types included AO/OTA 44-B2 (n = 1), 44-B3 (n = 6), 44-C1 (n = 2) and 44-C3 (n = 1). Postoperative complications were observed in 4 patients (40%), including 3 nonunions, 2 implant related complications and 1 wound infection. No wound healing disorder or below-the-knee amputation was observed. Four patients (40%) deceased between post-operative 6 to 16 months due to medical conditions unrelated to surgery. The mean Foot and Ankle Outcome Score was 52.6 (range 44.2-73.8).ConclusionHindfoot nailingis a viable treatment option in selected high-risk patients with an advanced age, unstable ankle fractures with significant bone loss, poor soft tissue condition and/or severely impaired pre-injury mobility. In a frail geriatric population, hindfoot nailing may be a safe alternative fixation method with a low risk of wound complication or major amputation. However, unprepared joint may lead to symptomatic nonunion after TTC intramedullary nailing.

Project description:A retrograde nail with posterior-to-anterior (PA) locking into os calcis, talus and tibia was used to correct deformity and achieve fusion after failed fusion. A variety of methods have been published to achieve union of the ankle and subtalar joint in a failed fusion situation. We have studied a retrograde locking nail technique through a 2.5-cm incision in the non-weightbearing part of the sole of the foot. Remaining cartilage in the ankle joint, where necessary, was percutaneously removed through an anterior approach and the locking nail was inserted after reaming of os calcis, talus and tibia. Locking screw insertion was in the sagittal plane (p.a. direction), in talus os calcis and tibial diaphysis using a nail mounted jig. Ten patients were entered in the study (age 27-60 years). The initial aetiology for attempted fusion was post-traumatic in nine cases and rheumatic in one case. There were 25 previous operations in the cohort not leading to fusion. An additional temporary external fixator was used in four cases to reach and maintain the optimum position for the procedure. The intervention time was 30-75 min. Dynamisation of the nail was performed after four months under local anaesthesia. The mean duration of follow-up was 4 years (3-5.5 years). Radiologically and clinically, fusion was achieved in 16 weeks (range, 12-20 weeks). There was no loosening of the implant or implant failure. A leg length discrepancy was avoided using this technique. There was one complication with varus malunion in a heavy smoker which united after corrective osteotomy, revision nailing and bone grafting. Patient satisfaction was measured on a scale (not visual analogue) of 0 (not satisfied) to 10 (completely satisfied); overall satisfaction averaged 9.5 points (range, 6-10 points). The postoperative ankle-hindfoot score of the American Orthopedic Foot and Ankle Society averaged 73.5 points (range, 61-81 points). Retrograde locked nailing with locking in the sagittal plane is a reliable minimally invasive procedure to achieve fusion of the ankle and the subtalar joint after failed fusion.

Project description:Tibiotalocalcaneal arthrodesis is most common and effective surgical treatment for severe hindfoot pathology, but the fusion rate is often lower than the ordinary tibiotalar arthrodesis because of the more serious joint disease associated with obvious deformity and osteoporosis. Recent literature describe tibiotalocalcaneal arthrodesis with reverse PHILOS plate with good clinical outcome result, though some patients non-union, due to eccentric force of the plate may be hidden. The purpose of this study was to evaluate clinical outcome of the lateral approach for tibiotalocalcaneal (TTC) arthrodesis with reverse PHILOS Plate and medial cannulated screw.Between Jun, 2013 to April, 2015 12 patient with hindfoot pathology had TTC arthrodesis with a reverse PHILOS plate with medial cannulated screw through a lateral approach with resection of the distal fibula and bone graft. Perioperatively observe for wound and neurovascular status. Patients were follow-up from post-operative 1, 3, 6 and12 months, to observation of wound healing, ankle pain, subtalar Joint Fusion, internal fixation and ankle function. Ankle function were scored according to the American Orthopaedic Foot and Ankle Society(AOFAS) Ankle-Hindfoot Scale system.Twelve ankle fusion all patient follow-up, with mean time to surgery 18.6 months (12-36 month). No cases infection and issue necrosis; one patient complaint of lateral foot numbness we observe and follow-up was spontaneously recovery after 3 months. After 3 months of operation, no obvious pain of ankle joint and internal fixations loose were found. Almost fusion and good axial alignment of TTC joint also were found by X-ray and CT examination. After final fellow-up of each case, no case complain of pain of ankle joint, good fusion and axial alignment of TTC joint were also all found through Terminology. The mean American Orthopaedic Foot and Ankle society (AOFAS) score average was 77.5.TTC arthrodesis with reverse PHILOS Plate and medial cannulated screw have advantages of clear incision, effective bone orthopaedic and graft fully secure, stable internal fixation, high fusion rate and less complications, can effectively correct deformities, alleviate hindfoot pain and improve function, and is an effective method of treatment of after severe hindfoot disease.This trial is registered on ClinicalTrials.gov with reference number: ID: NCT02977910 . Registered 26 Nov 2016, retrospectively registered.
