ABSTRACT Objectives Posterior tibial tendon dysfunction (PTTD) affects the support of the medial longitudinal arch and stability of the hindfoot. The purpose of this study was to assess the relationships of PTTD with foot and ankle functions and foot deformities in patients with rheumatoid arthritis (RA). Methods A total of 129 patients (258 feet) who underwent magnetic plain and contrast-enhanced magnetic resonance imaging were enrolled in this study. Positive magnetic resonance imaging findings were defined as tenosynovitis and incomplete and complete rupture of the posterior tibial tendon. Foot and ankle functions were assessed using the Japanese Society for Surgery of the Foot standard rating system for the RA foot and ankle scale (JSSF-RA) and self-administered foot evaluation questionnaire. Plain radiographs were examined for the hallux valgus angle, first metatarsal and second metatarsal angle, lateral talo-first metatarsal angle, and calcaneal pitch angle. Results PTTD was associated with motion in the JSSF-RA (p = .024), activities of daily living in JSSF-RA (p = .017), and pain and pain-related factors in the self-administered foot evaluation questionnaire (p = .001). The calcaneal pitch angle was significantly lower in the feet with PTTD than in those without PTTD (median: 16.2° vs. 18.0°; p = .007). Conclusions The present study shows that PTTD was associated with foot and ankle functions and flatfoot deformity. Thus, a better understanding of PTTD in patients with RA is important for the management of foot and ankle disorders in clinical practice.

The Right

We report a case of a 40-year-old woman with synovial sarcoma who presented with neural symptoms in the medial aspect of the right foot and ankle. The radiographic appearance of the foot and ankle was unremarkable, but magnetic resonance imaging showed a relatively well-defined enhancing lesion in the plantar soft tissues extending from the master knot of Henry to the posterior tibialis tendon. After orthopedic oncologic evaluation and workup, the patient was ultimately treated with a transtibial amputation, and no evidence of recurrence or metastatic disease was seen at 6-month follow-up.

Background Bone marrow edema (BME) of the talus is a rare, mostly self-limiting cause of foot and ankle pain. We sought to investigate in patients with idiopathic BME of the talus the effectiveness of pulsed electromagnetic fields and to determine the effect of this therapy on magnetic resonance imaging findings. Methods Six patients with BME of the talus confirmed by magnetic resonance imaging were enrolled. Pain was quantified with a visual analog scale from 0 (no pain) to 10 (the worst pain imaginable). The clinical outcome was assessed using the American Orthopaedic Foot and Ankle Society scoring system. Treatment consisted of pulsed electromagnetic field stimulation 8 h/d for 30 days. The device used generated pulses 1.3 milliseconds in duration, with a frequency of 75 Hz and a mean ± SD induced electric field of 3.5 ± 0.5 mV. Results The mean American Orthopaedic Foot and Ankle Society score improved from 59.4 (range, 40–66) before treatment to 94 (range, 80–100) at the last follow-up. The visual analog scale score decreased significantly from 5.6 (range, 4–7) before treatment to 1 (range, 0–2) at the last follow-up. Magnetic resonance imaging showed that BME improved after 1 month of treatment and resolved completely within 3 months in 5 patients, with normal signal intensity and no signs of progression to avascular necrosis. Conclusions A significant reduction in BME area was associated with a significant decrease in pain within 3 months of beginning treatment.

Marrow Edema

Background: We sought to determine the changes in the size of the edema observed on MRI scans and its relation to the patient’s pain during activity and pain during rest in bone marrow edema. Methods: A total of 26 patients were followed up at 3-month intervals for a period of 1 year. During the follow-ups, magnetic resonance imaging scans of the patients’ ankles were obtained; the scores obtained on the American Orthopaedic Foot and Ankle Society functional rating scale and visual analog scale were determined. The changes in these parameters and the correlation between them were examined. Results: The size of the edema as observed on magnetic resonance imaging scans decreased, and the pain during activity and rest decreased. Although there is a correlation between the decrease in the edema size observed on magnetic resonance imaging scans and decrease in the pain during activity, there is no correlation between the decrease in the edema size observed on magnetic resonance imaging scans and the decrease in pain during rest. Conclusions: Patients can be informed more precisely, that the pain during rest and activity may not decrease after the third and sixth month, respectively. Magnetic resonance imaging may not alter after the ninth month, so it may not be necessary to be performed again. (J Am Podiatr Med Assoc 101(5): 430–436, 2011)

Asymptomatic Individuals

Category: Ankle, Sports, Trauma Introduction/Purpose: The anterior talofibular ligament (ATFL) is one of the most commonly injured structures of the lower extremity after an ankle sprain. Evidence of remote injury to this structure is frequently encountered on magnetic resonance imaging (MRI) of the ankle, with uncertain clinical significance. Previous studies in the orthopaedic literature have discussed the prevalence of abnormal MRI findings in asymptomatic patients, most notably with regards to the spine and shoulder. More recently, a study on the prevalence of peroneal tendon abnormalities on routine MRI of the ankle was published. However, to our knowledge, no such study exists for the ATFL. The purpose of this study is to determine the prevalence of abnormal findings of the ATFL on MRI in asymptomatic individuals. Methods: All foot and ankle MRIs performed at our institution over a 4-month period were considered for inclusion in our study. Studies were excluded if performed on patients with documented ankle inversion injuries, ankle sprains, lateral ankle trauma, tenderness over the ATFL, or ankle instability. A total of 320 MRIs were eligible for inclusion. The integrity of the ATFL was noted in addition to the primary pathology. Results: The median age of the patients included in this study was 51 years with 203 females (63%) and 117 males (37%). One hundred eighteen (37%) of the 320 MRIs demonstrated some ATFL pathology. The most commonly encountered ATFL pathologies were thickening (38%), chronic tear (35%), attenuation (25%) and acute tear (2%). Conclusion: The results of this study demonstrate that a sizeable percentage of asymptomatic individuals (37%) will have ATFL abnormalities on magnetic resonance imaging of the foot and ankle. This study can have important clinical implications for patients who present with concerning MRI findings that do not correlate clinically. Based on our results, orthopaedic surgeons or any other physician providing musculoskeletal care can provide counseling and reassurance to patients who present with ATFL pathology on MRI but an absence of clinical findings. Much like MRI of the shoulder or spine, abnormalities must be correlated with the clinical exam.

Giant-cell tumor of the tendon sheath (GCT-TS) is an uncommon occurrence for a foot and ankle surgeon. However, there is a need to recognize the symptoms of typical and atypical presentations of this pathology. These benign neoplasms are recognized clinically as a soft-tissue mass that is usually painless and palpable. The foot and ankle account for only 3% to 5% of all GCT-TS in the body, with most being located in the hand. Giant cell tumor in the tendon sheath occurring in the foot and ankle is usually encountered on the lateral ankle and dorsum of the foot, occupying the extensor tendons. Additionally, it is commonly misdiagnosed clinically. This case study illustrates how early use of magnetic resonance imaging decreased patient morbidity with early recognition and excision of GCT-TS.
