Adverse events involving hallux metatarsophalangeal joint implants: Analysis of the United States Food and Drug Administration data from 2010 to 2018. Foot Ankle Surg 2021; 27:381-388. [PMID: 32505511 DOI: 10.1016/j.fas.2020.05.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 04/27/2020] [Accepted: 05/08/2020] [Indexed: 02/04/2023]
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
Background This study aimed to clarify the characteristics associated with postoperative floating of the lesser toes, especially focusing on the medial and lateral lessor toes, after arthrodesis of the first metatarsophalangeal joint and resection arthroplasty of the lessor toes in rheumatoid forefoot deformity. Methods Fourty-seven feet of 43 people who underwent resection arthroplasty of the metatarsal head of the lesser toes for rheumatoid arthritis of the metatarsophalangeal joints were included. We retrospectively evaluated the preoperative radiographic findings and clinical characteristics of the patients, and the occurrence of postoperative floating of the lesser toes. The mean duration of follow-up was 36.5 (range 12 to 114) months. Results Preoperative dislocation grades of the second and third toes that demonstrated postoperative floating were significantly higher than those of toes that did not experience postoperative floating. The hallux valgus deformity before surgery was significantly more severe in toes with postoperative floating of the second and third lessor toes than those with no floating (p < 0.05). In addition, the Japanese Society for Surgery of the Foot (JSSF) hallux scale scores before surgery in toes with postoperative floating of the fourth and fifth lessor toes were significantly worse than those in non-dislocating toes (p < 0.05). Conclusions The preoperative condition of the first metatarsophalangeal joint, including hallux valgus deformity, pain, range of motion, activity of daily living, and function is significantly different between postoperative floating of the lesser toes and non-floating of them after resection arthroplasty for rheumatoid forefoot deformity.

Abstract
BACKGROUND Ultrasonography is among the valid methods to assess articular cartilage in the foot. This study aimed to evaluate the validity of ultrasonographic grading to assess metatarsal head articular cartilage for rheumatoid forefoot deformity in vivo and to compare the findings with in vitro ultrasonographic and histologic gradings. METHODS Participants were 15 patients scheduled to undergo resection arthroplasty of the metatarsal heads of the lesser toes because of rheumatoid arthritis of the metatarsophalangeal joints. Ultrasonographic examination was performed in vivo the day before surgery. Specimens of the second to fifth metatarsal heads taken intraoperatively were graded from in vitro ultrasonographic and histologic evaluations. Correlations among in vivo ultrasonographic, in vitro ultrasonographic, and histologic gradings were analyzed. RESULTS In 46 metatarsal heads, the distribution of grading ranged from grade 1 to 6 for in vivo ultrasonographic examinations and from grade 1 to 4 for histologic examinations. In vivo ultrasonographic grading showed significant correlation to both in vitro ultrasonographic grading (P < .001, R = 0.74) and histologic grading (P < .001, R = 0.67). CONCLUSIONS The significant correlations between in vivo ultrasonographic and histologic gradings suggest that a semiquantitative in vivo ultrasonographic assessment of forefoot deformity in rheumatoid arthritis may be possible. Ultrasonographic grading may prove useful for pre- and postoperative evaluation of remaining joint function in rheumatoid forefoot deformity. An ultrasonographic grading system for remaining joint surfaces might be helpful in selecting surgical procedures such as joint-sparing osteotomy and metatarsal head resection.

Abstract
OBJECTIVES The introduction of powerful antirheumatic drugs has dramatically improved the treatment of rheumatoid arthritis (RA), leading clinicians to reconsider the benefits of joint preservation for rheumatoid forefoot deformities. We have employed joint-preserving forefoot surgeries, including rotational closing-wedge osteotomy of the first metatarsal. The aim of our study is to assess the short-term results of this procedure. METHODS From January 2011 through December 2011, 35 feet were treated with this procedure. Subjective, functional, and radiographic outcomes were surveyed. RESULTS The mean Japanese Society for Surgery of the Foot improved from a preoperative level of 52.6 to 68.7 postoperatively. The average hallux valgus and intermetatarsal angles improved from 47.3° preoperatively to 17.5° postoperatively, and from 16.7° preoperatively to 9.0° postoperatively, respectively. To assess the repositioning of pronation deformities of the first metatarsal, the position of the medial sesamoid was also surveyed according to the measurement system proposed by Hardy and Clapham. All feet except two were classified as grade V or higher preoperatively; 25 of these were grade IV or lower at the latest follow-up. CONCLUSIONS Rotational closing-wedge osteotomy of the first metatarsal was beneficial for correcting forefoot deformities in RA over the short term.

Abstract
BACKGROUND A standard rheumatoid forefoot reconstruction consists of arthrodesis of the first metatarsophalangeal (MTP) joint and resection arthroplasty of the lesser metatarsal heads. However, preservation of the metatarsal heads has gained renewed interest since the medical treatment of rheumatoid arthritis has improved dramatically. MATERIAL AND METHODS Nineteen consecutive patients with severe rheumatoid forefoot deformities underwent 24 forefoot reconstructions including first MTP arthrodesis with lesser MTP resection arthroplasty (resection arthroplasty group, ten feet), arthrolysis (arthrolysis group, six feet), or a combination of both (combined group, eight feet). Subjective, functional, and radiographic results were evaluated at 28 and 133 months (mean) followup. RESULTS The overall AOFAS Forefoot Score at short- and long-term followup improved significantly (all p < 0.0001). There were no substantial differences between groups with regard to subjective rating, function, use of orthopaedic aids or shoewear, and walking capacity. Radiographic evaluation revealed a significant increase in axial malalignment of the lesser toes at long-term followup in all groups (all p < 0.018). Sagittal malalignment increased substantially in the resection arthroplasty group only. Reoperation rate was comparable among all groups, and a single third MTP arthrolysis (3%, 1/40) was converted to resection arthroplasty. CONCLUSION In combination with first MTP arthrodesis, arthrolysis with preservation of all or only the lateral lesser MTP joints in rheumatoid forefoot reconstruction was a viable and durable alternative to resection arthroplasty when the joint destruction was mild to moderate.

Abstract
This study aimed to evaluate joint-preserving procedures by a modified Mann method for rheumatoid forefoot deformities and their functional outcomes in the mid-term. Eleven feet in seven patients underwent forefoot surgery using a modified Mann method for the big toe, combined with offset osteotomy or resection arthroplasty of the lesser toes. The mean follow-up period was 3.6 years. The mean score on the Japanese Society for Surgery of the Foot scale for rheumatoid arthritis foot and ankle joints improved from 44.0 to 72.0. The mean hallux valgus angle improved from 39.4 degrees to 20.5 degrees and the mean M1M5 angle improved from 31.1 degrees to 25.8 degrees . However, deformities involving a hallux valgus angle of more than 25.0 degrees recurred in three feet at the latest follow-up, although the patients did not complain of any symptoms from the recurrence. Improvement in the Sharp score for joint space narrowing was observed in the big toe, indicating better congruity of the metatarsophalangeal joint. For restraint of rheumatoid forefoot deformities, a modified Mann method, combined with offset osteotomy or resection arthroplasty, was satisfactory for not only improving the foot function, but also preserving the metatarsophalangeal joint mobility.

Abstract
This study evaluates the outcome of rheumatoid forefoot reconstruction with arthrodesis of the first metatarsophalangeal joint (MTPJ) combined with multiple Weil's metatarsal osteotomies (WMO) to the lesser rays. A retrospective study on 17 consecutive patients (26 feet) was performed with subjective, clinical, and radiological analysis. At an average follow-up of 26.2 months, patients rated the result in 88% of cases as excellent or good with 76% improvement in pain, 74% improvement in function, and 70% improvement in footwear. This corresponded with a high mean modified AOFAS score of 72/100 (34 to 90). First MTPJ arthrodesis union rate was 92%. Fourteen percent of lesser toes were aligned preoperatively compared to 86% at latest review. There was a 12% rate of recurrent metatarsalgia and or callosities. This combined procedure provides stabilization of the first ray, offloading the lesser metatarsals and preventing early recurrence of deformity. Preserving the lesser metatarsal head further widens the surgical options if revisional surgery is necessary in the future. ACFAS Level of Clinical Evidence: 4.

Abstract
Forefoot problems in patients who have rheumatoid arthritis are common. The progressive joint destruction causes a redistribution of weight about the forefoot, with a diminished weightbearing capacity of the first metatarsophalangeal (MTP) joint. Changes around the first MTP joint include synovitis, joint instability with subluxation, and arthritic change. Hallux MTP fusion in patients who have rheumatoid arthritis acts to permanently restore alignment and restore the medial column support of the foot, while at the same time enabling the first MTP to resume its original weightbearing role. Rheumatoid hallux MTP fusion and its rationale are reviewed.

Abstract
Surgical options for treatment of the hallux valgus deformity in the rheumatoid forefoot are numerous, but long-term results of many of these procedures have been less than satisfactory. Controversy exists as to whether excision or fusion is preferred for the treatment of the hallux metatarsophalangeal (MTP) joint. The role of replacement arthroplasty needs to be evaluated. The available surgical options for treatment of the arthritic first MTP joint in rheumatoid arthritis include arthrodesis, excision of the metatarsal head with or without interposition of the soft tissues, excision of the proximal phalanx, and silicone hinge replacement. This article discusses the various types of arthroplasty of the first MTP joint and the reported outcomes in the rheumatoid forefoot.

Abstract
To preserve the function of metatarsophalangeal joints and to ensure forefoot stability in patients with rheumatoid arthritis (RA), we performed a modified Hohmann method for hallux valgus (HV) and telescoping osteotomy or shortening of lesser toe deformities. Forty-seven RA patients (90 feet) with severe HV and forefoot deformities were examined. The indication for the procedure in all the patients was disabling foot pain secondary to intractable plantar callosities below the lesser metatarsal heads and painful HV deformities. The HV and intermetatarsal (M1M2) angles and sesamoid complex were measured on the preoperative and postoperative roentgenograms. Visual analogue scales were studied preoperatively, postoperatively, and in the follow-up period. HV and M1M2 angles significantly improved compared between the pre- and postoperative conditions. Out of the 47 patients, 78.9% were satisfied with the results of the operation, 8.9% were unsatisfied, and 12.2% reported fair results. There were several complications, such as painful callosity, which was recurrent in seven feet, and delayed wound healing was observed in two out of the 90 feet. A modified Hohmann method and abductor hallucis muscle correction are effective in relieving pain and ensuring the bony union of the great toe in spite of severe osteoporosis.

Abstract
To preserve the function of metatarsophalangeal joints and to ensure forefoot stability in patients with rheumatoid arthritis (RA), we performed a modified Hohmann method for hallux valgus (HV) and telescoping osteotomy of lesser toe deformities instead of fusion of HV or resection of all metatarsal heads. From October 1995 through March 2001, 47 RA patients (90 feet) with severe HV and forefoot deformities were examined. The indication for the procedure in all the patients was disabling foot pain secondary to intractable plantar callosities below the lesser metatarsal heads, painful HV deformities, and the severe deviation of the sesamoid complex diagnosed by the basis of X-ray images. The HV and intermetatarsal (M1M2 and M1M5) angles and sesamoid complex were measured on the preoperative and postoperative roentgenograms. According to the results of a questionnaire survey, the patients were divided into three groups using the visual analogue scale; group 1: satisfied, group 2: fair and or no pain, group 3: dissatisfied. HV and M1M2 angles significantly improved compared between pre- and postoperative or preoperative and the follow-up periods. Out of the 47 patients, 78.9% were satisfied with the results of the operation and 8.9% were dissatisfied. Of these patients, 12.2% reported fair results. There were several complications, such as painful callosity, which was recurrent in seven feet, and delayed wound healing was observed in two out of 90 feet. A modified Hohmann method and abductor hallucis correction are effective in relieving pain and ensuring the bony union of the great toe in spite of severe osteoporosis.

Abstract
We reviewed the results of arthrodesis of the first metatarsophalangeal joint and excisional arthroplasty of the lesser metatarsophalangeal joints performed on patients who presented intractable metatarsalgia and forefoot deformities. The study included 18 feet (15 patients) in 12 women and 3 men. The follow-up averaged 5.2 years. A good to excellent result was achieved in 15 (83%) feet; pain, which had been moderate to severe before surgery, was reduced to none to mild, and function, which had been severely limited before surgery, was improved to virtually unlimited. The fusion rate of the first metatarsophalangeal joint was 94% (17 of 18 feet). Thirteen of the 15 patients (87%) stated they would have the procedure again. This repair has been demonstrated to be a useful salvage procedure in nonrheumatoid patients with severe metatarsalgia secondary to failed forefoot surgery.

Abstract
Thirteen patients (14 feet) were treated for mild rheumatoid forefoot deformities with lesser toe partial proximal phalangectomies and partial syndactylizations. Eleven patients (85%) were reviewed at an average of 8 years postoperatively. The results were completely satisfactory in four patients, satisfactory with minor reservations in three patients, satisfactory with major reservations in one patient, and unsatisfactory in three patients. The major cause of reservations and lack of satisfaction was metatarsalgia. Seven patients (64%) reported that their activities were limited by intermittent metatarsalgia. Four patients (36%) considered the cosmetic appearance of the forefoot to be unsatisfactory. All but one patient required some form of shoewear modification. Based on this study, we believe the indications for this procedure are limited. These include rheumatoid patients with mild forefoot deformities without significant metatarsalgia or ongoing disease who have failed nonoperative treatment. Relative contraindications to this operation appear to include the recent onset of rheumatoid arthritis, active disease, significant metatarsalgia, and strong cosmetic concerns regarding outcome. In borderline clinical decisions that involve whether or not to leave or excise the lesser metatarsal heads, they probably should be excised to decrease late metatarsalgia.
