Do Dynamic Plantar Pressures Differ Based on Sonographic Evidence of Metatarsophalangeal Joint Synovitis in People With Rheumatoid Arthritis?
Libby Anderson et al
ACR Open Rheumatol. 2023 Dec 20

Objective: The metatarsophalangeal joints (MTPJs) are the most common location for synovitis in people with rheumatoid arthritis (RA), yet their association with plantar foot pressures has received very little attention. This study aimed to determine whether plantar pressures differed based on sonographic evidence of MTPJ synovitis in people with RA.

Method: Ultrasound was used to assess synovitis (grey scale synovial hypertrophy and power Doppler signal) in MTPJs 1 to 5 using the combined EULAR/Outcome Measures in Rheumatology scoring system. Peak pressure (PP) and pressure time integrals (PTIs) were assessed during barefoot walking for seven plantar foot regions (heel, midfoot, first metatarsal, second metatarsal, third to fifth metatarsals, hallux, lesser toes). Mixed-effects linear regression was used to determine the difference in PP and PTI between MTPJs with none/minimal synovitis and MTPJs with moderate/severe synovitis.

Results: Thirty-five participants with RA were included. Mean age was 66.3 years and mean disease duration was 22.2 years. Participants with sonographic evidence of moderate/severe synovitis at the first MTPJ had reduced PTI at the hallux compared with those with none/minimal synovitis at this joint (P = 0.039). Participants with moderate/severe synovitis at the second MTPJ and fourth MTPJ had reduced PP and reduced PTI at lesser toes compared with those with none/minimal synovitis in these joints (all P ≤ 0.048). No significant differences were observed for synovitis in other joints.

Conclusion: These findings may be suggestive of an inverse relationship between plantar pressure and soft tissue pathology, which is consistent with an offloading strategy and reduced use of the toes during propulsion.

Multifocal stress fractures in a patient with rheumatoid arthritis
Edwin Yuen Hao Tong et al
BMJ Case Rep. 2024 Jan 30;17(1):e254840

Stress fractures are often associated to activities that requires repetitive stress such as running. However, insufficiency-type stress fractures can also occur in patients with risk factors such as rheumatoid arthritis. Diagnosis of stress fracture would require a thorough clinical evaluation along with radiological imaging. However, this may be difficult due to how it mimics other musculoskeletal problems. The case of a woman in her 60s presenting with 2 months of severe ipsilateral right knee and ankle pain is used as an example. Based on initial clinical assessment and plain radiograph, her provisional diagnosis was osteoarthritis or inflammatory arthritis secondary to rheumatoid disease. However, MRI scan revealed that she had multifocal stress fractures in her knee, ankle and foot. Hence, we hope that this case study can allow clinicians to consider multifocal stress fracture as a possible diagnosis in patients with risk factors and to have lower threshold in performing MRI scans.

Reverse V-shaped osteotomy for ankylosing rocker-bottom foot deformity in patients with rheumatoid arthritis. A report of 3 cases
Takaaki Noguchi et al
Mod Rheumatol Case Rep. 2024 Jan 22

This study evaluated reverse V-shaped osteotomy for ankylosing rocker-bottom foot deformity in patients with rheumatoid arthritis. We experienced 3 feet: rheumatoid rocker-bottom deformities with painful and/or infectious bony prominence towards the bottom of the foot, treated with a reverse V-shaped osteotomy in the mid-hindfoot. In all three cases, significant correction was achieved with restoration of the medial longitudinal arch, and improvement in clinical scores was confirmed. Reverse V-shaped osteotomy has the potential to be a useful and definitive procedure for ankylosing rocker-bottom deformity in patients with rheumatoid arthritis.
