First Metatarsal-Phalangeal Joint Arthrodesis: Primary, Revision, and Salvage of Complications

The ability to wear heeled footwear following first metatarsophalangeal joint fusion

INTRODUCTION

Fusion remains the gold standard treatment for symptomatic first metatarsophalangeal joint (MTPJ) arthritis. Surgeons have traditionally advised female patients during the consenting process that they would have limitations or be unable to wear heeled footwear following first MTPJ fusion due to the loss of dorsiflexion at the first MTPJ. Anecdotally, surgeons have found that some patients were still able to continue wearing heeled footwear post fusion surgery. Heeled footwear has long been a trendy fashion accessory dating back from ancient Egyptian times and are regularly worn by a significant proportion of women today. Given the lack of literature in this matter, this study was conducted to investigate the effect of first MTPJ fusion surgery on the ability to wear heeled footwear, to aid in the consenting process.

METHODS

A retrospective review of 50 female patients who have had an isolated first MTPJ fusion between 2004 and 2015 at the authors' institution was undertaken with a follow-up telephone survey which included questions on ability to wear heeled footwear pre and post-operatively, duration, and the height of heels they could wear.

RESULTS

This study included 50 patients (62 feet) with a mean age of 63 years (range 43-78 years) at the time of surgery, with a mean follow-up of eight years (range 5-16years) from surgery. Of the 42 patients who wore heeled footwear pre-surgery, 26 (62%) continued wearing them. The majority of them (n = 23, 88%) were able to wear the same height heels. Patients could use heeled footwear from 30 min to eight hours continuously (mean=3 h) and, 88% were able to wear heel heights of 1.5 in. or higher. None of the patients wearing heeled footwear returned to the clinic with midfoot/hindfoot symptoms, one returned for worsening of pre-existing first IPJ (interphalangeal joint) symptoms.

CONCLUSION

This study has important implications for information given to patients during the consent process for this operation. The results have shown that many patients continue to wear heeled footwear following first MTPJ fusion with minimal or no symptoms in neighbouring joints.

Surgery Performed by Supervised Trainees Does not Affect Outcome in First Metatarsophalangeal Joint (MTPJ) Arthrodesis

First metatarsophalangeal joint (MTPJ) arthrodesis is an index procedure for orthopedic trainees in the United Kingdom. There is an absence of evidence as to the outcome of surgery when performed by supervised trainees. The aim of this study is to compare the incidence of fusion, complication rate and radiographic outcomes in first MTPJ arthrodesis performed by supervised orthopedic trainees with consultants. This is a retrospective cohort study of 117 patients undergoing first MTPJ arthrodesis from August 2015 to December 2017 in our institute for hallux valgus (HV) deformity with first MPTJ arthrosis or for hallux rigidus. Patients were followed to a minimum of 1-year postsurgery and were given an open appointment thereafter. In the hallux rigidus group, there was no significant difference between the complication rate (p = .477), incidence of fusion (p = .663), postoperatively HVA (p = .763), and postoperative intermetatarsal angle (p = .539) between trainees and consultants. There was a significant difference in mean tourniquet time (p = .563) between trainees and consultants. In the hallux valgus group, there was no significant difference in the complication rate (p = .519), incidence of fusion (p = .786), tourniquet time (p = .075), postoperative HVA (p = .423), and postoperative intermetatarsal angle (p = .143) between the trainees and consultants. This is the first MTPJ fusion series that demonstrates good results can be achieved by supervised trainees performing the procedure. This would suggest that first MTPJ arthrodesis remains an opportunity for trainees to continue learning to perform under supervision whilst ensuring no change in outcome for the patient.

Conversion of First Metatarsophalangeal Joint Arthrodesis to Interpositional Arthroplasty With Acellular Dermal Matrix for First Ray Ulceration: A Case Report

The purpose of this study is to report the outcome of the conversion of a first metatarsophalangeal (MTP) joint arthrodesis to an interpositional arthroplasty with an acellular dermal matrix for a chronic nonhealing first ray wound. To our knowledge, this is the first case report converting a first ray arthrodesis to an interpositional arthroplasty to heal a chronic ulceration. A 78-year-old female developed a chronic neuropathic ulceration under the first metatarsal head and hallux after a first MTP joint arthrodesis. The patient failed local wound care and underwent gastrocnemius recession, hallux interphalangeal joint fusion, and an interpositional arthroplasty with the use of an acellular dermal matrix. Bone tunnels were placed proximal to the metatarsal neck, where absorbable sutures affixed to the dermal matrix were passed from plantar to dorsal, and the graft was secured to the reamed metatarsal head and associated capsule. Postoperative radiographs revealed improved alignment of the first MTP joint. Complete reepithelialization of the plantar ulceration occurred within 2 weeks postoperatively. At the 16-month follow-up, the patient was ambulating without restriction and continued to be free of first ray ulceration and infection. This case study details the use of an acellular dermal matrix in an interpositional arthroplasty to offload a chronic nonhealing ulceration secondary to elevated first ray pressure associated with first MTP joint arthrodesis. The goal of this treatment is to reduce pain, heal the ulceration, and prevent its recurrence.

Revision of Failed First Metatarsophalangeal Joint Implant

Revision surgeries, as well as conversions from implants to arthrodesis, can present unique challenges to the foot and ankle surgeon. Proper perioperative planning assists in optimizing the outcome of the procedure. In general, some amount of bone loss and/or shortening of the first metatarsal takes place, leading to the need for augmenting the site with bone graft or a synthetic substitute. Fixation also plays a key role in obtaining a successful conversion. A solid construct combined with bone graft assists the foot and ankle surgeon in achieving an optimal outcome.

Surgical Treatment of Severe Hallux Abductovalgus With Dislocation of the First Metatarsophalangeal Joint: A Case Presentation and Surgical Technique

Severe hallux abductovalgus deformity with dislocation and contracture at the first metatarsophalangeal joint is difficult to manage, especially in the presence of concomitant, long-standing rheumatoid arthritis. This article highlights a novel surgical technique that may be used to successfully address this challenging condition while minimizing the likelihood of complications. Levels of Evidence: Level IV.

Long-Term Results of Surgical Treatment of Valenti Procedures for Hallux Rigidus: A Minimum Ten-Year Follow-Up Retrospective Study

Few studies reporting long-term results of surgical treatment of hallux rigidus have been published. The aim of this study is to assess the clinical outcome of Valenti procedures in a series of patients with hallux limitus/rigidus with a minimum 10-year follow-up time. We retrospectively evaluated 38 patients (40 feet) who underwent a Valenti procedure with a mean follow-up of 132 ± 19.6 (range 114 to 184) months. All patients were clinically reassessed on the basis of the evaluation of pain (visual analogue scale), function (American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal Scale Assessment and Foot & Ankle Disability Index), and subjective satisfaction. The scores before and after treatment, obtained from clinical recordings and clinical evaluation during the last follow-up visits, were compared. We found significant improvement of the mean values of the visual analogue score (p < .0001), Foot & Ankle Disability Index (p < .0001), and American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal Scale Assessment (p < .0001) during the latest follow-up visits. The results suggest that the Valenti technique represents a safe, reproducible surgical procedure that allows satisfying long-term results. The few reported complications were essentially the progressive worsening of the joint stiffness, but no sesamoiditis, metatarsal overload, secondary surgeries, or failures were documented.
