Joint Reliability

The purpose of this study was to first determine the intra-rater reliability of four different static measurement procedures used to assess first metatarsophalangeal joint extension range of motion and, second, determine which of the four static procedures provided a valid measure of the amount of first metatarsophalangeal joint extension required for normal walking. Twenty healthy adult subjects between the ages of 21 and 43 years participated in the study. Four static techniques were evaluated and dynamic first metatarsophalangeal joint extension was also determined from video recordings during walking. The results indicate that 1) all static measurement techniques were reliable; 2) the degree of first metatarsophalangeal joint extension obtained for each of the four static measurement techniques exceeded the amount of first metatarsophalangeal joint extension required for walking; 3) although each of the static measurement techniques was reliable, they should not be considered interchangeable; and 4) approximately 65 degrees of first metatarsophalangeal joint extension are required for normal walking.

Dimensional Finite Element

Two-dimensional finite element analysis was used to obtain the magnitude and distribution of the stresses in models of two different designs of a flexible one-piece double-stemmed first metatarsophalangeal joint implant. The loading and constraint conditions have been reported by previous researchers to occur in vivo at the joint during the push-off phase of the normal walking cycle. Based on the results obtained, the authors recommend the direction that future studies in this area should take.

The first metatarsophalangeal (MTP1) joint fusion is a very useful procedure in forefoot surgery and is still the gold standard for the treatment of severe and painful hallux rigidus. Normal walking and running are possible after MTP1 fusion, the first ray mobility being essentially in the interphalangeal (IP) joint with a compensatory hypermobility in dorsal flexion. Percutaneous MTP1 fusion is a simple procedure providing comparable results to fusions performed with open techniques. Postoperative cares are simplified with an immediate full weight bearing on rigid flat shoes and quick return to normal walking. Bone preparation is an important step and requires an experience in percutaneous forefoot surgery. Arthrodesis positioning and fixation with this percutaneous procedure are simple with possibility of clinical and radiological control. The indications for percutaneous MTP1 fusion are very large and only severe bone loss or osteoporosis represent the limits for this technique.

Hallux valgus is characterized by the appearance and growth of a painful “lump” in the region of the first metatarsophalangeal joint, the development of forefoot corns, and inability to choose the right shoes, which leads to a significant decrease in the quality of life of these patients. Corrective osteotomies that preserve the metatarsophalangeal joint, for example Austin (Chevron) osteotomy, are usually used for hallux valgus deformity of the I, II degrees. Radiography with the study of the hallux valgus angle (HVA), the intermetatarsal angle (IMA), the distal metatarsal articular angle (DMAA) is a research method that shows the true correlation between bone structures. The correlation between the radiological and functional indicators of osteotomy allows us to determine possible recommendations for indications for surgical treatment of Hallux valgus. Correlation shows that the largest correction of hallux valgus in older patients occurs due to a small adjustment of the angle of DMMA and HVA. IMA had the best correction after Austin osteotomy among patients of a younger age, then the HVA, and the DMMA had minimum correction according to the AOFAS rating scale (Kitaoka). The revealed correlations allow us to determine the correct tactics for the treatment of hallux valgus by identifying the benefits of Austin osteotomy.

Category: Bunion, Midfoot/Forefoot Introduction/Purpose: Hallux rigidus is a degenerative disease of the first metatarsophalangeal joint. Severe, end-stage hallux rigidus can become debilitating with surgical intervention becoming necessary once conservative measures and shoe modifications have failed. Joint salvage procedures include metatarsal phalangeal (MTP) arthrodesis and MTP arthroplasty. The purpose of this study was to assess for differences in patient reported outcomes in two cohorts who underwent fusion or joint reconstruction. Methods: This study was a retrospective review of prospectively collected data of 385 patients from an academic medical institution. Patients who underwent surgical intervention from July 2015 to November 2016 were identified based on CPT codes for MTP arthrodesis (28750) and arthroplasty (28293). We extracted outcome scores including SF12-M, SF12-P, FAAM, and VAS scores. Exclusion criteria included poly-trauma, revision procedures, and lack of pre and post-operative outcome scores. Mann- Whitney t-test was performed using GraphPad Prism version 7.0b for Mac to compare procedure groups, with significance define by a p-value of 0.05. Results: A total of eighteen patients met the inclusion criteria, with 6 who underwent arthroplasty and 12 arthrodesis. The average age was 63.7 amongst the cohort, with a total of 16 female and 2 males. Patients who underwent arthrodesis had better outcomes across all parameters. When comparing preoperative and postoperative scores, arthrodesis patients showed greater improvement of SF12-M (arthrodesis 9 vs arthroplasty -2, p=0.05), and SF12-P (9 vs -16, respectively p=0.05) scores. Arthroplasty patients were more likely to have a decrease in their SF-12 scores. VAS scores and FAAM scores showed no statistical difference between the two cohorts. Postoperative VAS scores were worse in 33% of arthroplasty patients despite surgical intervention, compared to 10% of arthrodesis patients. Conclusion: Our results suggests that both procedures provide a statistically significant difference in pain with several patients having a Global Rate of Change that is “very much better”. However, fusion of the metatarsophalangeal joint results in improved pain and functional outcomes for patients with severe hallux rigidus. These findings are consistent with current reports in the literature, which are mostly case series reports. Larger studies are needed to provide appropriate power and better support the findings of this study.
