Abstract
This article describes the etiology, clinical presentation, surgical management, and outcomes for treatment of the failed first metatarsophalangeal (MTP) joint arthroplasty. Failure following implant arthroplasty typically creates large osseous deficits and surgical management can be difficult. Salvage arthrodesis provides reliable joint stability while maintaining hallux length. Outcomes following conversion of a failed MTP joint arthroplasty to MTP joint arthrodesis have demonstrated consistent pain relief and high satisfaction: however, high rates of complication and nonunion have been reported. Bone graft may be necessary to fill large voids in the joint. Other revision options for failed arthroplasty have been described, but outcomes remain inconsistent and varied. Ultimately, conversion to MTP joint arthrodesis is the recommended intervention for treatment of the failed MTP arthroplasty implant, providing sufficient stability and pain relief.

Abstract
Cheilectomy, a joint-conserving procedure, is often a first-line choice for treating early stages of hallux rigidus. Recent evidence has revealed its efficacy in treating more advanced stages. However, when degeneration is profound, first metatarsophalangeal (MTP) fusion remains the most appropriate strategy. Nevertheless, it is common for surgeons to proceed initially with cheilectomy, reserving joint fusion for subsequent considerations if cheilectomy fails. This article will explore the relationship between the 2 procedures and evaluate the research surrounding the effect of prior cheilectomy on first MTP joint arthrodesis.

Abstract
First metatarsophalangeal (MTP) joint fusion, or arthrodesis, has been a cornerstone treatment for advanced joint degeneration since the 1950s, benefiting not only older patients but also younger individuals. The procedure boasts favorable long-term outcomes and a low rate of revision when fusion is successful. However, complications such as interphalangeal arthritis may occur, and nonunion or malunion can necessitate revision. While the first MTP fusion provides significant relief, its applicability varies, underscoring the need for careful patient selection.

Orthop Traumatol Surg Res 2024:103932. [PMID: 38987032 DOI: 10.1016/j.otsr.2024.103932] [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: 09/21/2022] [Revised: 02/26/2024] [Accepted: 03/12/2024] [Indexed: 07/12/2024]
Abstract
INTRODUCTION Arthrodesis of the first metatarsophalangeal joint (MTP1) is indicated for hallux rigidus, septic arthritis, severe hallux valgus (HV) or HV revision. Few studies have compared the functional and radiographic outcomes between indications. The goal of this study was to compare the results of MTP1 arthrodesis in patients with severe HV or HV revision at 6 months postoperative. The hypothesis was that there are no differences in the fusion rate, functional scores and radiological correction between the two groups. MATERIALS AND METHODS This was a retrospective, observational, single-center study conducted between January 1, 2018 and July 31, 2021. The inclusion criteria were patients treated for severe HV or HV revision by MTP1 arthrodesis with a compression screw and locking plate who were at least 18 years of age. The exclusion criteria were a history of septic arthritis of MTP1 without prior HV surgery, primary hallux rigidus, rheumatoid arthritis, incomplete medical record. The functional outcomes consisted of the Foot Function Index (FFi-f) and the European Foot and Ankle Society (EFAS) score. Radiographs were made to evaluate preoperative and postoperative deformity, the correction and the fusion rate. These outcomes were compared between two groups: severe HV and HV revision. RESULTS An analysis was done of 58 cases of MTP1 arthrodesis: 45 severe HV and 13 HV revisions. The mean patient age was 66 years, and the mean follow-up was 15.7 months. There were no significant differences between the two groups in the postoperative functional scores: EFAS (p = 0.85) and FFI-f (p = 0.14). At the final review, there were no significant differences between the two groups in the foot angle measurements (hallux valgus angle, p = 0.08 and intermetatarsal angle, p = 0.15) and fusion rate (p = 0.89) with a 93% fusion rate in patients with severe HV and 92% in patients with HV revision. CONCLUSION Given the good radiographic and functional outcomes, MTP1 arthrodesis by locking plate and compression screw is indicated as a first line surgical treatment for patients with severe HV or for patients undergoing HV revision. There is no evidence of a significant difference in the functional scores, fusion rate and radiographic correction between these two indications. LEVEL OF PROOF IV; retrospective case series.

Abstract
Background Arthrodesis of the first metatarsophalangeal joint is an effective treatment of advanced hallux rigidus. Numerous options have been described for performing this intervention. The aim of this study was to evaluate the outcomes following a consistent surgical technique of joint preparation with hand tools and fixation with 2 crossed screws and a dorsal compression plate. Methods Thirteen patients (16 feet) who underwent primary isolated arthrodesis of the first metatarsophalangeal joint between March 2019 and June 2021 were available for clinical, radiologic, and pedobarographic evaluation at a minimum of 12 months after surgery. American Orthopaedic Foot & Ankle Society scores, numerical pain rating scale, the radiologic hallux valgus and intermetatarsal 1-2 angles as well as the distribution of plantar pressure during gait were compared between the pre- and postoperative conditions. Results After an average follow-up period of 26 months, union was achieved in all cases and the mean AOFAS score raised significantly by 39 points. All the patients were satisfied with the result. Only 1 patient complained of mild residual pain at walk. Hardware removal was performed in 2 cases. The mean hallux valgus angle dropped from 12.3 to 6.3 degrees. The mean postoperative dorsiflexion angle was 21.6 degrees. After the procedure, peak pressure was significantly higher beneath the first metatarsal head and heel, whereas pressure-time integral was significantly lower beneath the hallux and medial lesser toes. Conclusion Arthrodesis of the first metatarsophalangeal joint with 2 crossed screws and a dorsal compression plate is a safe and effective treatment of advanced hallux rigidus. This procedure provides adequate pain relief and functional improvement of gait. Level of Evidence Level IV, therapeutic, retrospective case series.

Abstract
BACKGROUND First metatarsophalangeal joint (MTPJ) arthrodesis is a commonly utilised procedure. In this study, the authors aim to explore functional outcomes of patients undergoing nonsynchronous bilateral first MTPJ arthrodesis under the care of a single surgeon using a compression screw/locking plate construct. METHODS This is a prospectively collected, retrospectively analysed case series of fifty five patients who underwent bilateral nonsynchronous first MTPJ arthrodesis. Clinical and radiological outcomes were assessed preoperatively and at a minimum of two years postoperatively. Clinical outcomes were assessed using the Foot and Ankle Outcome Score (FAOS), the Self-Reported Foot and Ankle Score (SEFAS) and the Sports Questionnaire version 1 (SQ). Postoperative radiographs were used to assess evidence of union and compare both hallux valgus and intermetatarsal angles. Removal of hardware, revision surgery and correction of deformities were also recorded. RESULTS Fifty five patients were included in the study. There was statistically significant improvements in all five facets of the FAOS (p value < 0.05). The mean postoperative SEFAS was 45.1. In total, patients participated in thirteen different sporting activities. This represented 92 patient specific activities preoperatively and 104 postoperatively. The most common activities were walking, cycling and swimming. Overall, 94.5% (N = 52) of the cohort were satisfied with their return to sport while 98.2% (N = 54) would recommend bilateral first MTPJ arthrodesis. Mean reductions in hallux valgus angles and intermetatarsal angles were noted at 18.87 and 4.69 degrees respectively. There was one non-union in the cohort which required revision surgery. One patient required removal of hardware. CONCLUSIONS Bilateral first MTPJ arthrodesis is a safe and effective surgical option for patients with bilateral first MTPJ pathology. It has a high union rate, low complication rate and significantly improves clinical outcomes and allows patients reliably return to physical activities.

Abstract
There have been many reports describing the proposed alignment of a first metatarsal phalangeal arthrodesis to obtain optimum function. Most of these recommendations are based upon historical and anecdotal evidence. Furthermore, there are few reports directly comparing alignment to patient reported function. We studied radiographic sagittal plane alignment in a group of 60 patients (80 feet) who had undergone a first metatarsal phalangeal joint arthrodesis (20 of the 60 had bilateral arthrodesis) to better understand how this component of the arthrodesis position translates to real world function. The patients in this study had completed a functional survey in 2022 at a mean of 28.4 (median 27.8; range 13.2-45.7) months with very high satisfaction for return to activities of daily living and recreational sports. We measured the sagittal plane position of the first metatarsal relative to the proximal phalanx in this cohort with known post operative activity data. We found that a mean (standard of deviation) sagittal plane angle (angle between the anatomic axis of the first metatarsal and the proximal phalanx) of 15.4 (SD 7.4) degrees and a proximal phalanx head to ground height of 12.7 (SD 3.3) mm was present in this group. Comparing the functional and positional results we conclude that this sagittal plane position provides a good recommendation for alignment.

Abstract
INTRODUCTION First metatarsophalangeal joint (MTPJ) arthrodesis is a common treatment for various foot conditions, with nonunion as a frequent complication. The incidence of nonunion varies widely in the literature. In particular, males have a higher risk of nonunion than females. This is possibly due to biomechanical and anatomical differences, as men have on average larger feet than women. This study therefore aims to explore whether shoe size, as a proxy for foot size, affects nonunion rates and could explain the gender disparity in nonunion rates. METHODOLOGY An exploratory analysis of retrospectively collected data from patients who underwent primary first MTPJ arthrodesis in a single secondary hospital between January 2012 and December 2019. Additional data on body weight, height, and shoe size were prospectively collected from patients. RESULTS Among 261 included patients, 57 (21.8%) experienced nonunion. Nonunion incidence was higher in males (18, 26.9%) than in females (39, 20.1%). Self-reported shoe size showed no significant association with nonunion in both univariate and multivariate analyses. DISCUSSION The study's findings suggest that shoe size, as a proxy for foot size, is not associated with nonunion after the first MTPJ arthrodesis. Despite observing a gender difference in nonunion rates, this disparity could not be explained by shoe size. CONCLUSIONS Shoe size as a proxy for foot size appears to have no clinical association with nonunion following the first MTPJ arthrodesis.

Abstract
First metatarsal phalangeal joint and the first Tarsometatarsal arthrodesis have both been used for deformity correction and treatment of pain and arthritis. Concomitant arthrodesis of the first metatarsophalangeal and first tarsometatarsal joints (Double First Ray Arthrodesis) has rarely been described. We surveyed 29 patients who underwent double first-ray arthrodesis for primary or revision correction of hallux valgus. A custom questionnaire was used to assess their activities of daily living and sports activity at a mean follow-up of 19.6 months (median 18.4 months). Secondary endpoints were return to activity, deformity correction, and arthrodesis healing rate. The primary outcomes showed an excellent return to activities of daily living with 96.6% of patients capable of walking as much as they liked after surgery at a normal pace. About 96.6% reported they felt that their surgery was successful, they had no pain, and the loss of motion at the joint fusion sites did not affect their ability to perform daily activities. Protected walking in a fracture boot was initiated at a mean (SD) of 9.8 (9.9) days. Return to an athletic shoe occurred at a mean (SD) of 44.2 (11.7) days. Full unrestricted activity was at a mean (SD) of 105.2 (19.3) days with 65% of the patient group reporting that their recovery was easier than expected. There was 1 nonunion and no other complications. This data set supports the hypothesis that patients undergoing double first-ray arthrodesis can return to activities of daily living and sports with and low complication rate.

Abstract
Joint arthroplasty of the first metatarsophalangeal (MTP) joint is an accepted surgical option for patients with hallux rigidus. However, this procedure has been reported to have a high complication rate and unpredictable survivorship. Implant arthroplasty failure is a devastating complication that results in significant osseous defect with altered biomechanics of the foot. Commonly, salvage options are limited to arthrodesis with bone grafting. However, outcomes are rarely reported. The purpose of this study is to investigate the fusion rates of first metatarsophalangeal joint arthrodesis after conversion from failed implant arthroplasty. A systematic review of electronic databases to find reports of conversion arthrodesis after failed implant arthroplasty was performed. Six studies involving a total of 76 patients with a weighted mean age of 54.9 met the inclusion criteria. Out of the 6 included articles, the nonunion rate was 16.5% at a weighted mean follow-up of 48.1 months. The nonunion rate in the current report is higher than reported nonunion rates of primary arthrodesis. More prospective studies with consistent and standard outcome measures are needed to further determine the success rate of this salvage procedure.Levels of Evidence: 4, Systematic Review of Level 4 Studies.

Abstract
The traditional postoperative management of common foot and ankle procedures has involved a prolonged period of immobilization and nonweight bearing. The concern was loss of correction and fixation failure. However, it has been shown that a prolonged period of nonweight bearing can predispose patients possible deep vein thrombosis, disuse osteopenia, cardiovascular complications, and generalized deconditioning. The authors' institution has published studies reviewing the efficacy of early weight bearing after first metatarsophalangeal joint arthrodesis, modified Lapidus bunionectomy, and open reduction and internal fixation of ankle fractures. This article highlights the literature and rationale supporting the safety of early weight-bearing protocols.

Abstract
BACKGROUND The ideal fixation method for the first metatarsophalangeal joint (first MTP) remains uncertain. This study compares nonunion and revision surgery rates of first MTP arthrodesis between nonlocking semitubular plates and precontoured locking plates. METHODS Demographics, fixation technique, and complications of all patients who underwent primary first MTP arthrodesis between 2013 and 2018 were determined from radiographs and clinical records. Cost data were from a 1-year subset of isolated first MTP fusion surgeries. The primary outcome measures of this study were the nonunion and complication rates, with associated costs of patients undergoing first metatarsophalangeal arthrodesis with either a noncontoured semitubular plate or a precontoured locking plate. RESULTS The study included 189 patients, with a mean follow-up of 18.7 months. The overall nonunion rate was 10.1%, with no difference between the locking and nonlocking plates. The prevalence of a painful implant was also similar. Surgeries using locking plates cost an average of $1,500 more than those using nonlocked plates. CONCLUSIONS Because there was no difference in revision between locking and nonlocking plate fixation for primary first MTP arthrodesis, routine use of the more expensive locking plates may not be justified.

Abstract
BACKGROUND Percutaneous metatarsophalangeal arthrodesis is an option for the treatment of hallux rigidus in more advanced cases. The aim of this study was to investigate the clinical and radiographic results at least 2 years after percutaneous metatarsophalangeal arthrodesis in patients with hallux rigidus. METHODS This is a case series of consecutive patients undergoing percutaneous metatarsophalangeal arthrodesis in patients with hallux rigidus grades III and IV with a minimum of 24 months of clinical and radiographic follow-up. The primary outcome was clinical assessment using the Visual Analog Scale for Pain (VAS). Secondary outcomes included American Orthopedic Foot & Ankle Society (AOFAS) score, patient satisfaction, complications, and bone healing (radiographic analysis). RESULTS Between August 2017 and February 2020, 29 feet (24 patients) underwent percutaneous metatarsophalangeal arthrodesis. The mean follow-up was 38.4 (range 24-54) months. There was an improvement in the pain (VAS) from 7.8 to 0.6 (p < 0.001) and in the AOFAS score from 49.9 to 83.6 (p < 0.001). There was a rate of bone union of 82.8% and screw removal of 13.8%. All patients considered the result to be excellent or good. CONCLUSION The treatment of grade III and IV hallux rigidus with percutaneous metatarsophalangeal arthrodesis demonstrated high patient satisfaction and significantly improves in clinical outcomes but the nonunion rate was higher than reported outcomes for open 1st metatarsophalangeal joint arthrodesis. LEVEL OF EVIDENCE IV, case series.

Abstract
First metatarsophalangeal joint (MPJ) arthrodesis procedures are a mainstay of forefoot surgery and are associated with high rates of patient satisfaction for addressing a multitude of first ray pathologic conditions. This procedure is often also used as a fallback option for the revision of poor outcomes after other surgical procedures involving the first ray. Despite its successes, there remain instances of complications that can develop after primary first MPJ arthrodesis. This article reviews first MPJ arthrodesis as a procedure for revisional surgery of the first ray, and potential surgical options after failed primary first MPJ arthrodesis.

Abstract
Aim Osteoarthritis of the first metatarsophalangeal joint (MTPJ) is a common forefoot problem affecting patients in later years. It leads to pain, gait problems, and difficulty with activities of daily living. Treatment is controversial and varies according to patient symptoms and surgeon preference. Arthrodesis remains the gold standard but it has its own complications. It is associated with adjacent joint arthritis and transfer metatarsalgia. The aim of this study was to analyze the outcome of double-stemmed silastic joint arthroplasty (Wright-Medical, Memphis, TN) for end-stage hallux rigidus. Methods This retrospective analysis included 117 consecutive first MTPJ silastic arthroplasties done between January 2016 and February 2023 for end-stage hallux rigidus. There were 77 females and 40 males with a mean age of 65 years (46-82 years). Radiological and clinical assessments were performed, and patient-reported outcome measure data (PROMS) and visual analogue scale (VAS) scores were collected pre- and post-operatively. Results Findings showed 99.1% survivorship following a silastic joint arthroplasty with a mean follow-up of four years (six months to seven years). The MOXFQ (Manchester Oxford Foot Questionnaire) score improved from a mean of 81 (59.8-100) to 13 (0-57). The mean VAS scores improved from 7.2 (5-10) to 1.5 (0-7) postoperatively. Five patients were lost to follow-up. Two patients developed deep infection and one required revision. The other patient with infection was lost to follow-up. In total 10 patients (8.9%) developed complications, out of which eight patients responded to simple treatments. Conclusion Results have shown good to excellent outcomes following a silastic arthroplasty of the first MTPJ for the treatment of end-stage hallux rigidus. The survivorship at a mean follow-up of four years was 99.1% and the patient satisfaction rate was 90.1%. As historically reported, we did not see any soft tissue reaction or progressive osteolysis in any of our patients. It provides comparable and predictable outcomes to joint fusion for end-stage arthritis.

Abstract
First metatarsal phalangeal (MTP) joint arthrodesis has been employed for decades for pain related to arthritis and other associated abnormalities. Despite the commonality of the procedure there continues to be questions regarding functional expectations following the procedure especially when employed for correction of hallux valgus deformity. We surveyed 60 patients who had a tri plane MTP joint arthrodesis at mean 28.4 months (median 27.8) regarding their activities of daily living and sports activity through a direct conversation. Secondary endpoints assessed were return to activity, deformity correction and arthrodesis healing rate based on chart review and weightbearing radiographs. The primary outcomes showed robust return to all activities of daily living with 96.7% able to walk without restrictions and or pain, 98.3% were able to walk at a normal pace and 95% responded that loss of motion of their big toe did not affect their daily function. Regarding return to sports all patients that participated in sports before surgery resumed participation after with a trend toward increased sports activity. Early return to walking in a fracture boot was noted in this cohort at mean 4.1 days, return to athletic shoe at mean 6.3 weeks and full unrestricted activity at mean 13.3 weeks with no non-unions identified on radiographic or clinical exam. Deformity correction of the typical components of hallux valgus deformity was similar to previously published studies. This data set supports the hypothesis that patients undergoing first MTP joint arthrodesis can expect rapid and full return to activities of daily living and sports with a low complication rate.

Abstract
First metatarsophalangeal arthrodesis has been used to treat end-stage arthritis of the great toe (e.g., gout, post-traumatic, infection), severe hallux valgus deformity, hallux valgus caused by neuromuscular disorders, rheumatoid forefoot deformity, primary hallux varus, and rigid plantarflexion deformities, as well as a salvage procedure for failed previous operation of the great toe. As with any arthrodesis procedure, proper positioning of the hallux in first metatarsophalangeal arthrodesis is of utmost importance for good clinical outcome. The chief problem tends to be sagittal alignment. In case of the significant dorsiflexion malunion of the fusion site with excessive plantar pressure of the first metatarsophalangeal joint and abutment of the hallux to the shoebox, corrective osteotomy is indicated. If there is isolated excessive plantar pressure of the first metatarsophalangeal joint without hallux problem, arthroscopic sesamoidectomy and bone shaving of the plantar side of the first metatarsal head is another surgical option. The purpose of this technical note is to describe the details of arthroscopic sesamoidectomy and bone shaving of the plantar side of the first metatarsal head.

Abstract
Background First metatarsophalangeal (MTP) joint arthrodesis can be fixed using either a dorsal plate or crossed screws. However, there is considerable difference in the cost of these implants, and it is not known if there is sufficient difference in outcome that might justify this cost difference. Our aim was to compare the functional results and patient satisfaction rates after first MTP joint arthrodesis in a group of patients using the same surgical technique except for the fixation devices. Methods A prospective cohort of 27 patients who underwent first MTP joint fusion by the same surgeon using 2 crossed screws or a single screw with a dorsal plate was recruited over a 3-year period. Demographic information, patient satisfaction rates, complications, and union rates were evaluated. American Orthopaedic Foot & Ankle Society (AOFAS) and visual analog scale (VAS) scoring systems were used pre- and postoperatively to compare the functional outcomes. Thirty consecutive procedures (screws, n = 15; plate, n = 15) were performed. Age (55.8 ± 11.1 vs 63.3 ± 12.4 years for screws and plate respectively; P = .091) and female gender percentages (80% and 73%, P = .666) were similar between groups. Results The overall union rate was 93% with no differences between groups. AOFAS and VAS scores improved significantly postoperatively for each technique, and no differences were found between the two in the improvement in AOFAS (42.4 ± 8.0 vs 44.3 ± 8.2, screws and plate respectively; P = .520) and VAS scores (66.0 ± 5.4 vs 69.0 ± 6.9;P = .195). The implant cost for screws was $40 and for dorsal plate, $328. Conclusions First MTP joint fusion using either screws or plate fixation results in an improvement in AOFAS and VAS scores. Functional improvement and patient satisfaction did not differ between the 2 techniques, despite a considerable difference in cost between the two methods of fixation.

Abstract
Background Recalcitrant or persistent nonunions of the metatarsophalangeal (MTP) joint occur following failed MTP surgery for MTP fusion, failed MTP prosthesis, for hallux rigidus or due to infection and erosion. A deficient soft tissue envelope and compromised vascular supply of tissues in this region compound further attempts to salvage the great toe and preserve function. The medial femoral condyle (MFC) free flap provides vascularized corticocancellous bone and periosteum and has been successfully used for a variety of complex hindfoot and ankle pathologies. We present an additional indication with a small cohort study demonstrating its use in persistent nonunions of the first MTP joint. Methods A retrospective review was completed of all MFC flaps used for revision of failed first MTP joint fusion from January 2019 to November 2022. Demographic information, comorbidities, as well as clinical and radiologic follow-up was obtained from the patient charts. Results Three patients were included with MTP nonunion and an average of 7.5 (range, 5-11) failed prior surgeries. Mean age at index surgery was 50 (range, 46-57) years. An osseous union was achieved in all patients after 82 (range, 75-88) days. Hardware removal was possible after 81 (range, 55-98) days. Mean follow-up was 17 (range, 5-31) months. We note a 100% flap success rate without returns to the operating room. The lengths of the bone flaps were 2 to 4 cm, the volumes were 8 to 12 cm3. Fixation was performed with 1 intramedullary K-wire. The recipient vessel in all patients was the dorsalis pedis artery or a tributary thereof. All arterial anastomoses were performed under the operating microscope. Conclusion The MFC free flap is a reasonable option for salvage of complex recalcitrant or persistent nonunions of the first MTP joint. More prospective long-term studies with functional outcomes are necessary to confirm these findings. Level of Evidence Level IV, retrospective case series.

Abstract
BACKGROUND Fusion of the first metatarsophalangeal (MTP1) joint is a common surgery performed to correct hallux rigidus, hallux rigidus et valgus and other painful degenerative diseases of the MTP1.
AIM To assess outcomes of our surgical technique including non-union rates, accuracy and aims of correction.
METHODS Between September 2011 and November 2020 a total 72 of MTP1 fusions were performed using a low profile, pre-contoured dorsal locking plate and a plantar compression screw. Union and revision rates were analyzed with a minimum clinical and radiological follow up of at least 3 mo (range 3-18 mo). The following parameters were evaluated on pre- and postoperative conventional radiographs: Intermetatarsal angle, Hallux-valgus angle, dorsal extension of the proximal phalanx (P1) in relation to the floor and the angle between the Metatarsal 1 and the P1 (MT1-P1 angle). Descriptive statistical analysis was performed. Pearson analysis was used to assess for correlations between radiographic parameters and achievement of fusion.
RESULTS An overall union rate of 98.6% (71/72) was achieved. Two out of 72 patients did not primarily fuse with one patient suffering from a non-union, whilst the other demonstrating a radiological delayed union without clinical symptoms, with eventually complete fusion after 18 mo. There was no correlation between the measured radiographic parameters and the achievement of fusion. We believe the reason for the non-union was mainly attributed to the patient’s incompliance without wearing the therapeutic shoe leading to a fracture of the P1. Furthermore, we didn`t find any correlation between fusion and the degree of correction.
CONCLUSION With our surgical technique, high union rates (98%) can be achieved using a compression screw and a dorsal variable-angle locking plate to treat degenerative diseases of the MTP1.

Abstract
BACKGROUND Arthrodesis of the first metatarsophalangeal joint is the current treatment of choice for symptomatic advanced hallux rigidus and moderate-to-severe hallux valgus. There are different methods to perform arthrodesis, yet no consensus on the best approach. Therefore, this study aimed to determine the effects of preoperative and postoperative hallux valgus angle (HVA), joint preparation and fixation technique, and postoperative immobilization on the incidence of nonunion. METHODS A retrospective multicenter cohort study was performed that included 794 patients. Univariate and multiple logistic regression was conducted to determine associations between joint preparation, fixation techniques, postoperative immobilization, weightbearing, and pre- and postoperative HVA with nonunion. RESULTS Nonunion incidence was 15.2%, with 11.1% symptomatic and revised. Joint preparation using hand instruments (OR 3.75, CI 1.90-7.42) and convex/concave reamers (OR 2.80, CI 1.52-5.16) were associated with greater odds of a nonunion compared to planar cuts. Joint fixation with crossed screws was associated with greater odds of nonunion (OR 2.00, CI 1.11-3.42), as was greater preoperative HVA (OR 1.02, CI 1.00-1.03). However, the latter effect disappeared after inclusion of postoperative HVA in the model, with a small association identified between residual postoperative HVA and nonunion (OR 1.04, CI 1.01-1.08). Similarly, we found an association between odds of nonunion and higher body weight (OR 1.02, CI 1.01-1.04) but not of body mass index. CONCLUSION Based on our results, first metatarsophalangeal joint arthrodesis with planar cuts and fixation with a plate and interfragmentary screw is associated with the lowest odds of resulting in a nonunion. Higher body weight and greater preoperative HVA were associated with slight increase in rates of nonunion. It is crucial to properly correct the hallux valgus deformity during surgery.

Abstract
BACKGROUND The most common indications for revision of first metatarsophalangeal joint (MTPJ) arthrodesis are symptomatic failures of prior arthrodesis, failed hallux valgus correction, and failed MTPJ arthroplasty implants. However, the outcomes of revision MTPJ arthrodesis have rarely been studied. The purpose of this study was to compare the clinical, radiographic, and patient-reported outcomes of revision MTPJ arthrodesis following different primary procedures. METHODS A retrospective review of revision MTPJ arthrodesis cases between January 2015 and December 2019 was performed. The radiographic results, patient-reported outcomes, and rates of complications, subsequent revisions, and nonunions, were analyzed and compared preoperatively and postoperatively. A multivariate analysis was utilized to determine risk factors for complications and reoperations. RESULTS This study yielded a total of 79 cases of revision MTPJ arthrodesis. The mean follow-up time was 365 days (SD ± 295). The overall complication rate was 40.5%, of which the overall nonunion rate was 19.0%. Seven cases (8.9%) required further revision surgery. The multivariate analysis revealed that Diabetes mellitus was associated with significantly higher overall complication rates (p = 0.016), and nonunion was associated with "in-situ" joint preparation techniques (p = 0.042). Visual Analog Scale (VAS) significantly improved postoperatively (p < 0.001); However, PROMIS-10 physical health and PROMIS-10 mental health did not change significantly during the study period. CONCLUSION Treatment of MTPJ surgery failures is a clinical challenge in orthopedic surgery. In our study, revision of first MTPJ surgery resulted in higher nonunion rates and overall complication rates compared to typical outcomes from primary MTPJ arthrodesis. Diabetes, Tobacco use, and "in-situ" joint preparation technique were found to be independent risk factors for complications and reoperations. LEVEL OF EVIDENCE III-Retrospective Cohort Study.

Abstract
Arthrodesis of the great toe joint is a valuable procedure for hallux valgus deformities. The primary aim of this study was to determine nonunion rates of a first metatarsophalangeal joint (MTPJ) arthrodesis for bunion deformity. This was a retrospective review of 166 consecutive limbs that underwent a first metatarsal phalangeal joint arthrodesis at Wake Forest Baptist Medical Center (WFBMC). Procedures were performed using 4 different constructs for the arthrodesis. Incidence of nonunion, intermetatarsal correction, infection, and recurrence were measured. Overall, 20 patients (12%) experienced nonunion following a first metatarsophalangeal joint arthrodesis. Eighty-seven patients (86%) of plate and screw patients achieved union while 14 (78%) of crossing screw patients achieved union. The minimum time of follow-up was 3 months and the maximum time was 15.4 months. The mean change in intermetatarsal and hallux valgus angle correction was 3.4° and 20.3°, with no statistical difference based on hardware construct or being diabetic. First metatarsophalangeal joint arthrodesis is a viable option for hallux valgus. However, the results of the present study suggest that there is a lower fusion rate of the first MTPJ using crossing screws for bunion deformities.

Abstract
BACKGROUND This study compared radiographic and functional patient outcomes of 1st MTP arthrodesis between hallux rigidus (HR) and hallux valgus (HV) cohorts. METHODS A retrospective review was conducted at an academic medical center on patients who underwent 1st MTP arthrodesis during 2009-2021. In total, 136 patients (148 feet: HR=57, HV=47, combined=44) met the inclusion criteria of minimum three-month follow-up (mean=1.25 years, range=0.25-6.14 years). Data collection included patient-reported outcome measures (PROMs), radiographic markers, and complication and reoperation rates. RESULTS PROMs improved overall, with HV patients significantly improving the least. The HR group had a significantly smaller improvement in HV angle (HR=-3.6, HV=-17, Combined=-15 p < .001), intermetatarsal angle (H=-0.16, HV=-2.8, Combined=-2.6 p < .001), and 1st-5th metatarsal width (HR=-0.98, HV=-4.6, Combined=-4.6, p < .001). Complication and reoperation rates did not differ by group. CONCLUSION Outcomes of 1st MTP arthrodesis does not appear to differ between diagnostic indications of hallux rigidus, hallux valgus, or both. LEVEL OF EVIDENCE Level III, Retrospective cohort study.

J Foot Ankle Surg 2022; 61:1341-1347. [PMID: 35705455 DOI: 10.1053/j.jfas.2022.04.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 04/20/2022] [Accepted: 04/29/2022] [Indexed: 02/03/2023]
Abstract
The purpose of this systematic review and meta-analysis was to appraise and combine the available systematic reviews reporting nonunion incidence and prevalence in foot and ankle arthrodesis procedures. The Cochrane Library and MEDLINE were searched for relevant systematic reviews from inception to January 2022. Two independent reviewers selected and reviewed eligible studies. Studies were included if they were systematic reviews or meta-analyses reporting nonunion incidence and prevalence in foot or ankle arthrodesis procedures. Fourteen systematic reviews of 8 types of joint arthrodesis procedures were included for meta-analysis. These reviews comprised 138 studies with 5793 joint arthrodesis procedures. Quality of the included reviews were assessed using the AMSTAR2 checklist. Overall and subgroup meta-analysis of prevalence were performed using random effects model. Publication bias was determined by evaluation of a DOI plot with the Luis Furuya-Kanamori index of asymmetry. The pooled prevalence for foot and ankle nonunion rate was 8.1% (95% confidence interval [CI] 6.5%-9.9%). Overall prevalence of nonunion for single joint foot and ankle joint arthrodesis was 6.1% (95% CI 4.8%-7.6%). Subgroup analysis found that the highest rate of nonunion occurred during tibiotalocalcaneal arthrodesis with 27.1% (95% CI 19.4%-35.2%). We have reported the first meta-analysis of systematic reviews on nonunion rates in foot and ankle arthrodesis procedures. The overall nonunion rate for foot and ankle arthrodesis procedures was 8.1%. For single joint fusion procedures, the nonunion prevalence was 6.1%. Our reported nonunion rates are lower than previously published numbers.

Abstract
Background: Different fixation techniques are established for first metatarsophalangeal joint (MTPJ) arthrodesis, including compression screws, plates, Kirschner wires, metal- and bioabsorbable screws as well as staples. The purpose of this study was to investigate and present first clinical and radiologic results using a novel human, allogeneic cortical bone screw for arthrodesis of the first MTPJ. Methods: Arthrodesis of the first MTPJ was performed in 31 patients with hallux rigidus. Percentage union and time to union were the first outcomes; visual analog scale for pain, hallux valgus angle (HVA), intermetatarsal angle, and American Orthopaedic Foot & Ankle Society (AOFAS) hallux score were secondary outcomes. Results: Median time to union was 89 days, and union was observed in all patients. There were 4 complications (2 osteolysis margin, 1 cystic brightening, and 1 severe swelling at the first follow-up) all of that resolved at last follow-up. Pain significantly decreased from visual analog scale 8.0 to 0.2 points ( P < .0001). The HVA decreased from 30.4 to 10.2 degrees in the patient group with deformities. The total AOFAS score increased significantly from 48 to 87 ( P < .0001). Conclusion: Primary and revision arthrodesis of hallux rigidus with the human, allogeneic cortical bone screw reveals satisfying results similar to clinical and radiologic outcomes of other surgical techniques. Within 1 year, the human, allogeneic cortical bone screw is fully remodeled to host bone. Level of Evidence: Level IV, retrospective case series without control group.

Abstract
Hallux rigidus can be treated with a variety of surgical procedures, including joint preserving techniques, arthrodesis, and arthroplasty. The most commonly reported complications for joint preserving techniques consist of progression of arthritis, continued pain, and transfer metatarsalgia. Although good outcomes have been reported for arthrodesis overall, careful attention must be paid to technique and positioning of the toe to avoid nonunion or malunion. Arthroplasty preserves motion but in the case of failure can present the additional challenge of bone loss. In these scenarios, the authors recommend distraction bone block arthrodesis with structural autograft.

Abstract
Background First metatarsophalangeal joint arthrodesis is commonly performed for symptomatic end-stage hallux rigidus. It has been postulated to produce good results in the literature. Various fixation techniques offer differences in union rates, complications and functional outcomes, stirring debates about which produces the best outcomes for patients. Therefore, this review aims to synthesise and compare the outcomes of modern fixation techniques used for first metatarsophalangeal joint (FMPJ) arthrodesis. Methods The electronic database searched were PubMed, CINAHL, Cochrane Library, and Google Scholar. The critical appraisal skills programme tool for cohort study was used. The interventions consisted of screw(s), plate(s), and staple(s). Studies comprising outdated fixation techniques such as suture, metallic wire, external fixation, Rush rods or Steinmann pins were excluded. Participants were adults over 18 years, undergoing FMPJ arthrodesis in the UK. Studies with the population consisting primarily of revision cases, patients with rheumatoid arthritis or diabetes were excluded. Results Seven UK studies included 277 feet and a 95.7% overall union rate at a mean union time of 83.5 days. Staples had the highest union rate of 98.2% at mean union time of 84 days, followed by plates (95.2%, 92 days), and finally screws (94.9%, 71 days). The overall complication incidence is 5.8%. All of the fixation techniques produced good functional outcomes postoperatively. Conclusions Whilst staple techniques showed the highest union rate, plating techniques are preferable over screws or staples for better results across several outcome measures, including reduced complication incidence, stability, early ambulation, and good functional outcome. The Manchester-Oxford Foot Questionnaire and EuroQol-5Dimensional are recommended as measurement tools to assess functional outcomes following FMPJ arthrodesis.

Abstract
The complication rate for an arthrodesis of the first metatarsophalangeal joint remains high. To improve results, we used a complete intraosseous fixation device (IOFIX) with proposed biomechanical advantages. Our hypothesis is that this technique has at least an equal union rate and less hardware irritation compared to other techniques. Seventy procedures were performed in 55 patients. Average follow-up was 24.5 months. All patients returned to follow-up after 6 weeks and were evaluated for union. Fifty-nine feet (84%) completed full follow- up. Union occurred in 62 of 70 feet (88.5%). Eight feet had nonunion at 1 year follow-up. Average time to fusion was 51 days. Three of 59 feet had malunion. No hardware removal was necessary. In conclusion, an MTP1 arthrodesis using IOFIX provides consistent and good functional outcomes. Due to the low-profile design, no hardware removal was necessary. However, union rates seem slightly lower compared to other techniques.

Clinical Outcomes After First Metatarsophalangeal Joint Arthrodesis by Flat Cut Joint Preparation With Individual Adjustment for Sagittal Alignment. J Foot Ankle Surg 2022; 61:60-66.

Abstract
Sagittal misalignment is a major cause of patient dissatisfaction and re-operation after first metatarsophalangeal (MTP) joint arthrodesis. The stereotypical application of the fixed angle would be undesirable, especially in cases of flat or cavus foot. We retrospectively reviewed 31 cases (27 patients) in which first MTP joint arthrodesis was performed using the flat cut joint preparation technique with reference to the plantar clearance beneath the pulp of the toe while simulating weightbearing by pushing a board against the sole. The most common underlying cause of surgery was rheumatoid arthritis (22 cases [71%]). Clinical outcomes were evaluated by the Japanese of Surgery of the Foot (JSSF) hallux scale and the self-administered foot evaluation questionnaire (SAFE-Q). Twenty-three cases were also examined by pedobarography to evaluate postoperative walking plantar pressure. At the most recent follow-up of a mean 19.6 months, the toe-to-floor distance of the hallux in static standing posture was a mean of 2.5 mm (range, 0-10 mm). All but 1 foot (97%) achieved bone union. There were no complications or revisions due to misalignment of the fused MTP joint. JSSF hallux scales improved significantly from 47 preoperatively to 82 postoperatively. All subscale scores except general health and well-being in the SAFE-Q improved significantly at final follow-up versus preoperative period. Plantar pressure under the hallux was correlated with the toe-to-floor distance but not radiographic parameter. In conclusion, first MTP joint arthrodesis achieved good clinical outcomes when using toe-to-floor distance and Kirschner wire template for flat cut joint preparation.

Abstract
Arthrodesis of the first metatarsal phalangeal joint (MTPJ) is a widely utilized surgical procedure for a wide array of metatarsal pathologies. This study aims to explore the functional limitations following first MTPJ arthrodesis, overall satisfaction and patient's abilities to achieve activities of daily living (ADL). This prospective cohort study assessed functional limitations as well as footwear and lifestyle restrictions using several questionnaires. One hundred and three participants who had a first MTPJ arthrodesis under the care of a single surgeon were recruited. Pre- and postoperative patient-reported outcome measures were recorded. The American Orthopaedic Foot and Ankle Score (AOFAS) and the Manchester-Oxford Foot Questionnaire were also used to further examine functional status. Hallux valgus angle (HVA) and intermetatarsal angle (IMA) were compared using preoperative and postoperative weightbearing radiographs and successful fusion was recorded. Complications were documented and are discussed in detail. The duration of follow-up was more than 12 months. There was one nonunion in the cohort while 2 patients experienced delay to fusion. Approximately 97% of patients were very satisfied with the procedure and their ability to achieve ADLs post operatively. A further 82.5% of patients were able to return to wearing nonadaptive footwear. The mean reduction in HVA and IMA was 21.78° and 6.84°, respectively. This study demonstrates the safe and successful use of a compression screw/locking plate construct for arthrodesis of the first MTPJ. Furthermore, the study provides clear evidence of high levels of functionality after the procedure with statistically significant differences (p value <.05) in all 4 facets of the AOFAS questionnaire as well as several notable differences in activity levels and footwear restrictions pre and postoperatively.

Abstract
Multiple fixation techniques for first metatarsophalangeal joint arthrodesis have been described with an average fusion rate of 93.5%. This retrospective cohort study assesses the association between crossed screws (vs dorsal plating) and medical comorbidities and the outcome radiographic union. Bivariate tests of association and multivariable logistic regression were employed to assess differences across fixation type and outcomes. We identified 305 patients who underwent a first metatarsophalangeal joint arthrodesis during the study period. Crossed screw fixation was used in 158 (51.8%) patients while dorsal plating (tubular or anatomic locking plate) was used in 147 (48.2%) patients. Dorsal plating was utilized more often in patients with rheumatoid arthritis (p = .019) and history of smoking (p = .044). At 12 weeks post-operatively there were no significant differences in fusion rates between the two groups (crossed screw group = 95.3% vs dorsal plate group (referent) = 93.5%, Adjusted odds ratio (AOR) 1.39, 95% confidence interval [CI] 0.45-4.26). Not smoking was associated with a greater odds of fusion at 12 weeks (96.2% for nonsmokers vs 75.0% for smokers (referent), AOR 0.07, 95% CI 0.02-0.28). Lower body mass index was associated with a greater odds of fusion at 12 weeks (AOR 0.90, 95% CI 0.82-0.99). Surgeons allowed weightbearing earlier with dorsal plate fixation (2 weeks (interquartile range [IQR] 2.6) versus 5 weeks (IQR 2.6) for crossed screw fixation, p = .001). Patients with multiple medical comorbidities were more likely to require revision surgery than patients having 0-1 comorbidities (p < .05). Crossed screws can provide an inexpensive yet effective option for first metatarsophalangeal joint arthrodesis.

Abstract
First metatarsophalangeal joint (MTPJ) arthrodesis is currently the gold standard technique for advanced hallux rigidus. This retrospective study aimed to identify the risk factors for nonunion after first MTPJ arthrodesis with a dorsal locking plate and compression screw construct. Between April 2014 and April 2019, 165 consecutive patients (28 men and 137 women; mean age, 60 (range, 28-84) years) who underwent 178 primary first MTPJ arthrodeses were retrospectively reviewed. All arthrodeses were performed using either a dorsal locking plate with an integrated compression screw (Anchorage CP plate, Stryker, n = 97) or a dorsal locking plate (Anchorage V2 plate, Stryker, n = 81) with a separate compression screw (4 mm cannulated ACE screw). Union was defined as bone bridging across the fusion site on at least 2 of the 3 standard foot radiographs (anteroposterior, lateral, oblique) and no MTPJ movement or pain during clinical examination. Potential risk factors for nonunion were analyzed with the use of univariate and multivariate analyses. The overall nonunion rate was 6.2% (11 of 178 cases). The risk factors identified in the univariate analysis included preoperative hallux valgus deformity, postoperative residual hallux valgus deformity, and diabetes (p < .05). Multivariate analysis confirmed that postoperative residual hallux valgus deformity (odds ratio 6.5; p= .015) and diabetes (odds ratio 7.4; p = .019) are independent risk factors for nonunion after first MTPJ arthrodesis. Diabetes is the most important independent risk factor for nonunion after first MTPJ arthrodesis with a dorsal locking plate and compression screw construct. A residual postoperative hallux valgus deformity is associated with a significantly increased risk for nonunion. It is therefore crucial to correct the hallux valgus deformity to a hallux valgus angle of less than 20°.

Abstract
Background. We present clinical and functional results of first metatarsophalangeal joint (MTPJ) arthrodesis using Memory staples. Methods. This retrospective observational study reviewed MTPJ arthrodesis with Memory staples from 2012 to 2016. Results. The mean age of 50 patients (55 feet) was 63 years (range 41-77 years). Forty-one feet were in women. Indication was hallux rigidus (n = 49) and hallux valgus (n = 6). The overall union rate was 98.2% (n = 54 of 55), including delayed healing in 3 (5.5%). The average time to union was 12 weeks. At a mean follow-up of 38 months (range 12-73 months), the mean Foot and Ankle Ability Measure score (47 out of 55, 86% response rate) was 87% (interquartile range 78%-100%). Complications included partial laceration of extensor hallucis longus (n = 1), wound infection (n = 4), wound-related (n = 2), lesser metatarsalgia (n = 3), cock up deformity (n = 1), and pain (n = 3). Conclusions. The high union rate, good patient satisfaction scores, and low rate of complications support our use of Memory staples.Levels of Evidence: Therapeutic, Level IV.

Abstract
BACKGROUND The aim of this study was to determine if a single or separate construct with interfragmentary screw was associated with higher rates non-union following first metatarsophalangeal joint (MTPJ) arthrodesis. METHODS A retrospective analysis of patients undergoing first MTPJ arthrodesis between April 2010 and June 2017 was performed. Patients who received either a single (Stryker Anchorage 1 MTP Cross Plate) or separate (Stryker Anchorage 1 MTP locking plate with one Asnis partially threaded compression screw) construct locking plate and interfragmentary compression screw were reviewed. Descriptive statistics were generated for sample demographics and between-group differences were calculated. Multivariable regressions explored internal fixation type and association with non-union. RESULTS A total of 280 first MTPJ arthrodesis met the inclusion criteria and were reviewed. The incidence of non-union was 7.9% of procedures (22 joints). Following multivariable binary logistic regression, the single construct locking plate with interfragmentary compression screw was associated with an increased risk of non-union (OR 3.43, 95% CI 1.26-9.33), adjusting for age, gender and comorbidity. CONCLUSIONS A single construct interfragmentary screw and locking plate (Stryker Anchorage 1 MTP Cross Plate) was associated with an increased incidence of non-union following first MTPJ arthrodesis.

Abstract
Successful deformity correction utilizing first metatarsophalangeal (MTP) fusion for hallux valgus with concomitant degenerative changes of the first MTP joint is well documented. Currently, there is limited discussion in the literature focusing on triplanar correction of the first MTP arthrodesis. Presented is a novel approach for triplane correction and fusion of the first MTP joint utilizing a biplanar locked plating system.

Abstract
Arthrodesis of the first metatarsophalangeal (MTP) joint has been established as the “gold standard” for the treatment of several first ray disorders, due to its perceived efficacy and the consistently reported good results in the literature. Arthrodesis is a commonly performed procedure for the treatment of end stage arthritis, rheumatoid arthritis with severe deformity, selected cases of severe hallux valgus (with or without signs of degenerative joint disease), as well as a salvage procedure after failed previous operation of the first ray. The goals of a successful 1st MTP arthrodesis are pain alleviation and deformity correction in order to restore a comfortable gait pattern and to improve shoe wear. Several techniques have been reported with several proposals regarding the preparation of the articular surfaces and the method of definitive fixation. As with any given surgical procedure, various complications may occur after arthrodesis of the 1st MTP joint, namely delayed union, nonunion, malunion, irritating hardware, etc.

Abstract
Hallux rigidus is the most common arthritic pathology of the foot. This review article discusses the pathophysiology and common clinical presentation of hallux rigidus. Furthermore, we discuss multiple classification systems that categorize the arthritic process and guide management. Surgical interventions include cheilectomy, Moberg osteotomy, synthetic cartilage implants, interpositional arthroplasty, and arthrodesis. The common complications are reviewed, and the rates of these complications highlighted. Surgical options for hallux rigidus globally have successful outcomes with low rates of complications when done on appropriate patients.

Abstract
In this multicenter study, we evaluated commonly used methods of fixation and 2 methods of joint preparation for first metatarsophalangeal joint fusion, in terms of radiological union and revision rates. Included were 409 consecutive fusions in 385 patients. The overall union rate was 91.4% (34/409). About 29.4% (10/34) of our nonunions were symptomatic. Preoperative hallux valgus showed a statistically significant relation to nonunion (odds ratio [OR] = 9.33, p = .017). Other potential contributing factors like gender (OR 1.9, p = .44), diabetes (OR = 0, p = .99), steroid use (OR = 2.07, p = .44), inflammatory arthritis (OR = 0, p = .99), and smoking (OR = 2.69, p = .34) did not attain statistical significance. Further, the methods of fixation like solid screws (OR = 0, p = .99), plate (OR = 3.6, p = .187), or cannulated screws (OR = 0.09, p = .06) showed no correlation with incidence of nonunion. We compared 2 techniques of joint preparation and found no significant difference in union rates (chi-square = 1.0426, p = .30). Our crude comparison of costs showed the average saving to the trust per year could be 33,442.50£ by choosing screws over plates. To conclude, only hallux valgus had a statistically significant relation to nonunion. All other variables had no significant impact on the union. Solid screw seems to be economically the most viable option and a valid alternative.

Abstract
The incidence of nonunion after first metatarsophalangeal joint (MTP-1) arthrodesis was found to be high in our clinic. By raising awareness for the problem, making a uniform surgical treatment protocol, banning the commonly used convex-concave reamers, and promoting solely the use of hand instruments to prepare the joint for arthrodesis, we tried to decrease the numbers of nonunion. This prospective cohort study included all patients who underwent MTP-1 fusion between January 2018 and March 2019. Patients were treated according to a standardized protocol, using hand instruments to prepare the joint for fusion. Anthropometric and therapy-related data were collected and compared with an earlier 2015-2016 cohort that was retrospectively assessed. Furthermore, the frequency of nonunion between convex-concave reamers and hand instruments was compared. A total of 53 patients underwent MTP-1 fusion surgery. The incidence of nonunion was 3.8%, significantly lower than the 24.1% in 2015 to 2016 (p = .002). Multivariate regression analysis showed a 7.11 times higher risk of nonunion in 2015 to 2016 compared with 2018 to 2019 (95% confidence interval [CI] 1.55 to 32.55) (p = .012). Furthermore, an increase of 10° in HVA showed a 1.52 risk of occurrence of nonunion (95% CI 1.07 to 2.17) (p = .021). The use of convex/concave reamers was univariately associated with a 3.61 times higher risk of nonunion (95% CI 1.14 to 11.43) (p = .029); however, after correction for preoperative HVA, the preparation method was no longer associated with the occurrence of nonunion (p = .108). Patients suffering from severe hallux valgus had nonunion in 32.1% of cases. Incidence of nonunion after MTP-1 arthrodesis was significantly reduced by raising awareness and by standardizing the treatment protocol. There was no significant difference in nonunion frequency between the methods of joint surface preparation. Severe hallux valgus is prone to nonunion, and more research into this indication for MTP-1 fusion and outcome is needed.

Abstract
This work concerns a biomechanical study aiming to ascertain the optimal type of joint resection when performing a joint arthrodesis. A 3-dimensional digital model of the first metatarsophalangeal joint including the entire first metatarsal bone and proximal phalanx using CT scans of the forefoot was created. Using this computer model, 4 types of resections; ball-and-socket, flat-on-flat, wedge 90°, and wedge 100° were simulated. Parameters measured using this model were the force necessary to separate the 2 fused surfaces, the surface area of the resected surfaces and the shortening of the first ray. By measuring the reactive force necessary to separate the phalanx from the first metatarsal, the 90° wedge resection was found to be the most stable, with comparable results in the case of the 100° wedge resection. Wedge resections are also more favorable when comparing the shortening of the first ray. Wedge resections, though being more technically difficult to perform prove to be the most stable for metatarsophalangeal joint-1 arthrodesis using this model.

Abstract
BACKGROUND The prevalence of osteoarthritis of the hallux metatarsophalangeal joint (MTPJ) is 1 in 40 people over the age of 50. Surgical treatment options for MTPJ arthritis include joint preservation, joint resurfacing, and arthrodesis. Hallux MTPJ implants have evolved over the past several decades, but are associated with various complications. The aim of this study was to examine the MAUDE database to determine reported adverse events for hallux MTPJ implants. MATERIALS AND METHODS The US Food and Drug Administration's (FDA) Manufacturer and User Facility Device Experience (MAUDE) database was reviewed from 2010 to 2018 to review voluntary reported adverse event reports for approved implants within the United States. We recorded the type of adverse event and excluded duplicate reports and those extracted from already published literature. RESULTS Among 64 reported hallux MTPJ implant adverse events, the most common modes of adverse events were component loosening (34%), infection (14.1%), component fracture (9.4%), inflammation (9.4%), and allergic reaction (7.8%). Regarding implant type, Cartiva SCI had the highest percentage of adverse events (23.4%), followed by Arthrosurface ToeMotion (20.3%), Ascension MGT (12.5%), Arthrosurface HemiCAP® (10.9%), Futura primus (9.4%), and Osteomed Reflexion (6.3%). There was an increase in reported adverse events after 2016. The MAUDE database does not report the total incidence of implant insertion. CONCLUSION Our study of the MAUDE database demonstrated that component loosening and infection are the most common modes of adverse events for hallux MTPJ implants. Cartiva accounted for one-fourth of the implant-related adverse events during our study period, followed by ToeMotion, and Ascension MGT implants. Continued reporting of adverse events will improve our understanding on short and long-term complications of various hallux MTPJ implants.

Abstract
AIMS To assess the results of a biomechanical test of cadaveric specimens, comparing 2 methods of fixation of modified Lapidus arthrodesis in combination with arthrodesis of the first metatarsophalangeal joint. METHODS A total of 12 cadaveric specimens were used in the test. Arthrodesis of the first MTP joint was in all patients fixed with a Variable Angle LCP 1st MTP Fusion Plate 2.4/2.7. Two methods of fixation of the Lapidus arthrodesis were compared, i.e. fixation with two screws in the PS (plate-screw) version versus fixation with X-Locking Plate 2.4/2.7 in the PP (plate-plate) version. Measurements were obtained with the use of a testing machine ZWICK Z 020-TND with an optical device Mercury RT for measuring deformities. Each specimen was subjected to 3 loading options, a. displacement 5 mm, the support is placed under the proximal phalanx, b. displacement 5 mm, the support is placed under the first metatarsal head and c. load to failure, the support is placed under the first metatarsal head. RESULTS In all specimens the PS construct showed a statistically considerably higher stiffness than the PP construct. In all specimens treated with the PP construct the load to failure was lower than in the PS construct. For loading mode a., at a significance level of 0.05 (P<0.05), the P-value was 0.036, for mode b. the P-value was 0.007 and for loading mode c. the P-value was 0.006. In addition, age-related decrease in stiffness of the specimen was proved at a significance level of 5% (P=0.004). CONCLUSION In all the three loading modes, the PS (plate-screw) construct showed a statistically higher stiffness than the PP (plate-plate) construct.

Abstract
BACKGROUND Nonunion rates in hind or midfoot arthrodesis have been reported as high as 41%. The most notable and readily modifiable risk factor that has been identified is smoking. In 2018, 14.4% of the UK population were active smokers. We examined the effect of smoking status on union rates for a large cohort of patients undergoing hind- or midfoot arthrodesis. METHODS In total, 381 consecutive primary joint arthrodeses were identified from a single surgeon's logbook (analysis performed on a per joint basis, with a triple fusion reported as 3 separate joints). Patients were divided based on self-reported smoking status. Primary outcome was clinical union. Delayed union, infection, and the need for ultrasound bone stimulation were secondary outcomes. RESULTS Smoking prevalence was 14.0%, and 32.2% were ex-smokers. Groups were comparable for sex, diabetes, and body mass index. Smokers were younger and had fewer comorbidities. Nonunion rates were higher in smokers (relative risk, 5.81; 95% CI, 2.54-13.29; P < .001) with no statistically significant difference between ex-smokers and nonsmokers. Smokers had higher rates of infection (P = .05) and bone stimulator use (P < .001). Among smokers, there was a trend toward slower union with heavier smoking (P = .004). CONCLUSION This large retrospective cohort study confirmed previous evidence that smoking has a considerable negative effect on union in arthrodesis. The 5.81 relative risk in a modifiable risk factor is extremely high. Arthrodesis surgery should be undertaken with extreme caution in smokers. Our study shows that after cessation of smoking, the risk returns to normal, but we were unable to quantify the time frame. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Abstract
First metatarsophalangeal joint (MTPJ) arthrodesis is a surgical treatment option for failed first MTPJ procedures. In cases of failed MTPJ arthroplasty, removal of failed implants and necrotic bone can cause shortening and biomechanical insufficiency of the first ray. Distraction arthrodesis with bone grafting can be used to maintain first ray length. We describe a technique of autograft harvest from the ipsilateral calcaneus. We present a retrospective case series of clinical and radiographic outcomes of distraction arthrodesis with bicortical calcaneal autograft in patients with failed procedures of the first MTPJ. We achieved a 100% osseous union rate. There was an insignificant change in first ray length from preoperative to postoperative (P = .2402). First ray length was maintained with a median autograft length of 10 (range 5 to 14) mm. We were able to correct first ray deformity with a significant reduction in preoperative to postoperative intermetatarsal angle and hallux abduction angle (P = .0156, P = .0068, respectively). Seven (88%) of 8 patients with available subjective follow-up were satisfied with the outcome of the procedure and would undergo the procedure again. Our results indicate that first MTPJ distraction arthrodesis with calcaneal autograft is a viable option for failed first MTPJ procedures. Surgeons who implement our techniques can expect high rates of osseous union, deformity correction, and patient satisfaction.

Abstract
Objective: The standard therapy for a symptomatic hallux rigidus is still the arthrodesis of the first metatarsophalangeal (MTP) joint. A nonunion of the arthrodesis is a possible postoperative complication. This study aimed to evaluate the incidence of nonunion associated with first MTP joint arthrodesis and identify risk factors influencing this. Methods: This retrospective study included 197 patients who were treated with an isolated first MTP joint arthrodesis. The severity of MTP-related osteoarthritis was assessed clinically and radiologically prior to surgery according to the Waizy classification. Patient characteristics and radiological parameters were evaluated postoperatively. Results: A full clinical and radiological data set was collected from 153 out of 197 patients. We identified 14 cases of nonunion and found that nonunion was associated with higher incidence of male gender (P = .29), comorbidity (P = .035), higher grade of osteoarthritis (P = .01), and increased postoperative great toe dorsiflexion (P = .022). Conclusions: Arthrodesis of the first MTP joint is a safe operative treatment, as demonstrated by a nonunion rate of 9.2%. Negative influencing factors were the presence of preexisting diseases, higher grades of osteoarthritis, and a relative increased dorsiflexion position of the great toe after surgery. These factors should be considered during pre-, intra-, and postoperative planning.Levels of Evidence: Therapeutic, Level IV: Retrospective.

Abstract
BACKGROUND Arthrodesis of the first metatarsophalangeal joint (MTPJ) is a frequently performed surgical procedure. Many patients have bilateral hallux MTPJ pathology requiring bilateral arthrodesis. There are concerns that bilateral simultaneous hallux surgery, under one anaesthetic, results in the patient being severely incapacitated in the early post-operative period. We hypothesize that bilateral simultaneous hallux MTPJ fusions does not compromise outcomes or the patients' post-operative comfort and rehabilitation and is cost and time effective. METHODS In this retrospective study, 16 patients who underwent bilateral simultaneous first MTPJ arthrodesis were compared to 16 patients who had unilateral MTPJ arthrodesis with regards to outcome, tolerance, cost and time effectiveness. Outcome measures were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) hallux score and the Self-Reported Foot and Ankle questionnaire (SEFAS). RESULTS There was a significant improvement in the AOFAS scores post surgery in the bilateral group and according to the SEFAS grading, 14 patients (87.5%) had good or excellent outcome scores with 13 (81.25%) of these patients having excellent scores. This was comparable to the outcome scores in the unilateral group. Two patients developed non-unions bilaterally compared to one in the unilateral group. There is also a notable general cost saving and less time off work when bilateral fusions are done at the same setting. CONCLUSION Bilateral simultaneous hallux MTPJ arthrodesis is an effective, convenient and cost effective option for patients requiring MTPJ fusions for bilateral hallux pathology.
