Tibiotalar Arthrodesis

Background: The aim of this prospective study was to evaluate and analyse the first clinical results of a recently developed low-profile anatomic plate in combination with two headless compression screws for tibiotalar arthrodesis. Methods: The case series involved 20 consecutive patients who underwent ankle arthrodesis using a hybrid technique. Radiographs were obtained at 6 and 12 weeks and 1 year postoperatively. The outcome was evaluated by using AOFAS and SF 12-questionnaire. Any complications related to the arthrodesis were recorded. Results: The follow-up rate was 100%. Patients mean age at the time of surgery was 60.1 years (range, 40-79). Arthrodesis with full weight-bearing occurred in every patient within 12 weeks postoperatively. There were no patients with delayed union, non-union, infection or implant failure. AOFAS Score and SF-12 scores increased considerably compared to preoperatively. Conclusion: The hybrid technique for ankle arthrodesis is a tibiotalar compression with screws in combination with rigid anterior plate fixation. Our clinical results demonstrated no implant failure, no infection and fusion in any of the 20 patients. Further studies are necessary to support our first results.

Category: Ankle; Ankle Arthritis; Arthroscopy Introduction/Purpose: Tibiotalar arthrodesis is a common procedure for the treatment of ankle arthritis. Arthroscopic arthrodesis with screw fixation has become increasingly popular with reported shorter hospital stays, shorter time to fusion, and equivalent patient reported outcomes to open arthrodesis with screw fixation. However, there is limited research comparing arthroscopic arthrodesis to open arthrodesis with a modern anterior locking plate. The aim of this study was to determine if the use of a modern anterior locking plate in primary ankle arthrodesis would have a similar time to fusion versus arthroscopic arthrodesis with screw fixation. Methods: We performed a retrospective case review of primary ankle arthrodesis cases from 2009 to 2018 that utilized either an open approach with an anterior locking plate or an arthroscopic approach with screw fixation. All open cases were performed by a single surgeon using an anterior locking plate; all arthroscopic cases were performed by another surgeon using cannulated screw fixation. Post-operative protocol was similar for both patient groups, with at least 6 weeks of casting and protected weight- bearing followed by a transition to removable cast-boot and progressive weight-bearing. Exclusion criteria included combined tibiotalar/subtalar arthrodesis, hindfoot arthrodesis, cases where infection was suspected pre-operatively, and revision arthrodesis for any reason (IE, infection, failed total ankle arthroplasty, prior nonunion). Time to fusion was based on evaluation of post- operative radiographs performed at six and ten weeks. Results: 28 open and 25 arthroscopic arthrodesis cases met inclusion criteria. The fusion rate at six weeks was 82.1% (open) versus 72% (arthroscopic). At ten weeks the fusion rate was 100% (open) versus 91% (arthroscopic). 4/28 open arthrodesis cases experienced continued pain versus 8/25 arthroscopic. For the open procedure, one patient required reoperation for skin grafting away from the incision due to a poor-fitting workboot. Two patients had removal of painful hardware; one of these patients required a second reoperation for symptomatic neuroma resection. For arthroscopic cases, two patients had removal of hardware and one patient had an elective below-knee amputation for intractable pain. Average patient age was 53.3 years (open) versus 48.4 (arthroscopic). Average length of hospital admission was 2.3 days (open) versus 0.9 (arthroscopic). Conclusion: Open tibiotalar arthrodesis with a modern anterior locking plate resulted in faster time to radiographic fusion and a lower incidence of continued pain compared to arthroscopic arthrodesis in this study. The faster time to fusion may be due to the superior biomechanical stability of a locking construct. Arthroscopic arthrodesis resulted in shorter hospital admissions, and neither group had any incision-related complications. In this case series, open and arthroscopic fusion had comparable outcomes.

Abstract Background Internal fixation is recommended for treating Vancouver B1 periprosthetic femoral fractures. Although several fixation procedures have been developed with high fixation stability and union rates, long-term weight-bearing constructs are still lacking. Therefore, the aim of the present study was to evaluate the stability of a double-plate procedure using reversed contralateral locking compression-distal femoral plates for fixation of Vancouver B1 periprosthetic femoral fractures under full weight-bearing. Methods Single- and double-plate fixation procedures for locking compression-distal femoral plates were analysed under an axial load of 1,500 N by finite element analysis and biomechanical loading tests. A vertical loading test was performed to the prosthetic head, and the displacements and strains were calculated based on load-displacement and load-strain curves generated by the static compression tests. Results The finite element analysis revealed that double-plate fixation significantly reduced stress concentration at the lateral plate place on the fracture site. Under full weight-bearing, the maximum von Mises stress in the lateral plate was 268 MPa. On the other hand, the maximum stress in the single-plating method occurred at the defect level of the femur with a maximum stress value of 1,303 MPa. The principal strains of single- and double-plate fixation were 0.63 % and 0.058 %, respectively. Consistently, in the axial loading test, the strain values at a 1,500 N loading of the single- and double-plate fixation methods were 1,274.60 ± 11.53 and 317.33 ± 8.03 (× 10− 6), respectively. Conclusions The present study suggests that dual-plate fixation with reversed locking compression-distal femoral plates may be an excellent treatment procedure for patients with Vancouver B1 fractures, allowing for full weight-bearing in the early postoperative period.

ABSTRACT Ankle osteoarthritis patients are young and lack of available long last treatment. Ankle arthrodesis remains the gold standard and is the procedure of choice for younger patients who are heavy laborers. These case series evaluate and report five patients undergone ankle arthrodesis at RSUD Dr. Soetomo Surabaya on 2012-2016. The data were collected from patient files, radiographs, and a recent physical examination. The outcome has been assessed with SF-36 score and clinical scoring system Ankle-Hind foot American Foot and Ankle Society. Three male patients and two female patients underwent ankle arthrodesis with cannulated screw, caused by neglected severe ankle dislocation. One patient had open dislocation. Based on SF-36 scoring, the five patients had average score 76,7 with highest and lowest score were 95,9 and 56,7. Based on clinical score ankle-hind foot American Ankle and Foot Society, the average score was 68(51 – 88). The scoring result includes general health, physic, emotional, and social. And clinical scoring ankle-hind foot American Foot and Ankle Society evaluation includes pain, function, and alignment. It shows that there was patient that gains an almost perfect result. Patient with the lowest score also had knee osteoarthritis contralateral from the operated ankle. Early weight bearing on ankle arthrodesis with cannulated screw was the major factor caused unsatisfactory result of this patient. Ankle arthrodesis with cannulated screw has satisfactory result eventhough remain complain on one patient. Nevertheless, ankle arthrodesis with cannulated screw still has an important role in the treatment of choice on ankle reconstruction.Keywords                   : Ankle arthrodesis, cannulated screw, ankle joint fusion

AbstractFor patients with tumors of the distal femur, options for limb salvage include tumor resection followed by reconstruction. While reconstruction commonly involves a distal femoral replacement, careful selection of patients with tumor involvement limited to a single condyle may be candidates for reconstruction with distal femur hemiarthroplasty. In these procedures, resection spares considerably more native anatomy. Three consecutive patients who underwent resection and reconstruction at the distal femur with custom unicondylar hemiarthroplasty are presented in this case series at a mean follow-up of 45 months (range, 26–78). In two cases, prostheses were utilized as a secondary procedure after failure of initial reconstruction. In one case, the custom prosthesis was utilized as the primary method of reconstruction. Mean Musculoskeletal Tumor Society disease-specific scores were 26.7 (range, 25–28). All patients achieved a return to full weight bearing, activities of daily living, and functional range of motion. In appropriately selected patients with tumors of the distal femur, reconstruction with custom unicondylar hemiarthroplasty provides benefits including optimal function postoperatively via preservation of tumor-free bone and ligamentous structures. Additionally, maintenance of greater bone stock may confer benefits to patients with pathology at a high likelihood for recurrence and need for subsequent procedures.

Between January 1, 2011, and January 1, 2017, an orthopaedic foot and ankle surgeon performed tibiotalar arthrodesis on 221 patients. Thirty-two were included in this study. Inclusion criteria included patients with at least one risk factor for nonunion and/or malunion, isolated anterior ankle arthrodesis with plate fixation, patients older than 18, and a minimum of 1-year follow-up. Risk factors were avascular necrosis of the talus, severe segmental bone defect, smoking, inflammatory arthropathy, coronal deformity greater than 15°, diabetes mellitus, septic nonunion, failed ankle arthrodesis, and body mass index greater than 35. Functional outcome questionnaires (Ankle Osteoarthritis Score [AOS] and Foot Function Index [FFI]) were collected at the latest visit or by phone. Twenty-six (26/32, 81.2%) patients included in the study had computed tomography images available for review at an average of 3.2 months after surgery. The rate of successful arthrodesis was 93.8% (30/32) at an average of 78 days. Overall, 14 patients (14/32, 43.8%) developed a postoperative complication, including 1 patient that had a delayed nonunion and 2 patients that proceeded to nonunion. Twenty-three patients (23/32, 71.9%) completed the functional outcome questionnaires at an average of 26.8 months. Mean AOS and FFI scores improved significantly postoperatively ( P < .001). Sagittal tibiotalar and coronal tibiotalar alignment improved significantly in patients with severe preoperative deformity ( P < .001). Tibiotalar arthrodesis with anterior plate fixation in a high-risk cohort results in high union rates and significantly improved functional outcomes.

Background: Although early accelerated rehabilitation is recommended for the treatment of acute Achilles tendon rupture, most traditional rehabilitation techniques require some type of brace. Methods: We retrospectively analyzed 44 feet of 44 patients (25 male and 19 female) with a mean age of 31.8 years who had an acute Achilles tendon rupture related to athletic activity. Patients had been treated by a double side-locking loop suture (SLLS) technique using double antislip knots between stumps and had undergone early accelerated rehabilitation, including active and passive range of motion exercises on the day following the operation and full weight-bearing at 4 weeks. No brace was applied postoperatively. The evaluation criteria included the American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Scale (AOFAS) score; active plantar flexion and dorsiflexion angles; and the intervals between surgery and the time when patients could walk normally without any support, perform double-leg heel raises, and perform 20 continuous single-leg heel raises of the operated foot. Results: Despite postoperative early accelerated rehabilitation, the AOFAS score and active dorsiflexion angles improved over time (6, 12, and 24 weeks and 2 years). A mean of 4.3 ± 0.6 weeks was required for patients to be able to walk normally without any support. The mean period to perform double-leg heel raises and 20 continuous single-leg heel raises of the injured foot was 8.0 ± 1.3 weeks and 10.9 ± 2.1 weeks, respectively. All patients, except one who was engaged in classical ballet, could return to their preinjury level of athletic activities, and the interval between operation and return to athletic activities was 17.1 ± 3.7 weeks. Conclusion: The double SLLS technique with double antislip knots between stumps adjusted the tension of the sutured Achilles tendon at the ideal ankle position and provided good clinical outcomes following accelerated rehabilitation after surgery without the use of a brace. Level of Evidence: Level IV, retrospective case series.

Introduction: The historic primary treatment for end-stage first metatarsophalangeal (MTP) joint arthritis has been fusion. Traditionally, this has been accomplished by metaphyseal apposition between the proximal phalanx and metatarsal using crossed compression screws. Recently, locked plates have been introduced that help support this technique by offering added stability. We present our experience with 45 first MTP fusions in 45 feet using a locked plate and compression screw. Methods: A retrospective review of 45 patients who met the study criteria with a hallux rigidus correction using a locked plate with a compression screw was performed. Charts and radiographs were independently reviewed by 2 authors not involved in the index procedures to assess outcomes. Results: There was a 93% fusion rate (42/45 feet) with 3 nonunions. The mean time to union was 51.1 days (range = 29-116 days, SD = 24.4). The mean patient age was 58.1 years (range = 29-80 years, SD = 10.1). The mean time to partial weight bearing was 7.0 days (range = 0-53 days, SD = 13.8) and the mean time to full weight bearing was 62.0 days (range = 29-57 days, SD = 17.9). Discussion: We report on the results of first MTP fusion using a compression screw and locked plate technique. The results show that this is an effective means of creating a first MTP joint arthrodesis. Levels of Evidence: Therapeutic, Level IV, Case series

Background: Total hip (THA) and total knee arthroplasty (TKA) are becoming an increasingly standard procedure in the whole world. In conjunction with an aging population and increased prevalence of osteoporosis, proper management of periprosthetic, and interprosthetic fractures is of great interest to orthopedic surgeons. This study aims to report the clinical and radiographic outcomes, complications and reoperations of IFFs in geriatric patients. Methods: A retrospective single-institution case series study was conducted. Between 2011 and 2019, 83 patients underwent surgical treatment for periprosthetic femoral fractures. Thirteen fractures were identified as IFFs. Patient demographics and comorbidities were collected preoperatively, and fractures were classified with the Vancouver and AO unified classification system (AO-UCS). Results: We included 12 patients (13 hips) with IFFs (AO-UCS type IV.3 B (2/13) type IV.3 C (3/13), type IV.3 D (8/13)). The average patient age was 86.54 (range, 79-89) years. There were 10 females and 2 males. Perioperative morbidity has been identified in 10 of the 12 patients, and the 3-month and 1-year mortality were reported in 2 and 3 patients, respectively. Cerclage cables were used in 9 of 12 patients. One of 12 patients showed a local complication, with no documented implant failure or revision. Patients achieved complete union and returned to their preoperative ambulatory status, and full weight-bearing at an average of 5 (range, 2 to 7) months later. Conclusion: Management of IFF can be challenging because these fractures require extensive surgical expertise. Locking plate seems to be a valuable treatment option for geriatric patients with IFFs. Despite the complexity of this type of fracture, the overall complication and revision rate, as well as the radiographic outcome are good to excellent. Level of Evidence: Level III, Therapeutic study.
