Objectives
Hallux valgus (HV) is a progressive foot deformity in which the first metatarsophalangeal (MTP) joint is affected. The relationship between the dome height of the first metatarsal head and the HV deformity has not been studied previously. This study aimed to investigate a possible relation of the dome height of the first metatarsal head with articular alignment and the hallux valgus angle (HVA), which is frequently used to evaluate HV.
Methods
A total of 129 feet of 68 patients were included in the study. Anteroposterior digital radiographic images of the foot taken in a weightbearing, standing position were used to assess the HVA, dome height, and shape of the first metatarsal head and the alignment of the MTP joint. The dome height of the first metatarsal head is the vertical distance from the base to the highest point of the articular surface doming. The alignment was categorized into three groups: aligned, deviated, and subluxated. Patients were assigned into three groups based on the HVA: Normal, Mild HV and Moderate HV.
Results
A statistically significant, positive correlation was found between the HVA and the dome height of the first metatarsal head (r = 0.293, P = 0.001 and P < 0.05). The dome height was significantly lower in the patients with a normal HVA than those with a high HVA (P 1 = 0.042, P 2 = 0.039 and P < 0.05, respectively). The dome height of the first metatarsal head was found significantly higher in feet with subluxation, compared to feet aligned and deviated (P 1 = 0.001; P 2 = 0.0089 and P < 0.05, respectively).
Conclusions
Our study results suggest that HV deformity may be related to an increased dome height and the measurement of the dome height of the first metatarsal head might be used to evaluate an anatomic tendency toward HV development.
Background:
Extracorporeal shockwave therapy (ESWT) has recently been used as a new treatment modality for plantar fasciitis. We aimed to determine the efficacy of ESWT by magnetic resonance imaging (MRI) findings.
Methods:
Thirty patients with plantar fasciitis who had received no treatment for 6 months were included. Extracorporeal shockwave therapy was applied once a week for a total of three sessions (frequency of 12–15 Hz, 2–3 bars, and 2,500 pulses). All of the patients were assessed with the visual analog scale, a 6-point evaluation scale, the Foot and Ankle Outcome Score (FAOS), and MRI findings before and 3 months after ESWT. Visual analog scale scores were used in determining the pain level of patients in the morning, during activity, and at rest. Foot and ankle–related problems were evaluated with the FAOS.
Results:
The duration of painless walking according to the 6-point rating scale, the FAOS, and pain showed significant improvements after ESWT (P < .05). Significant decreases in MRI findings, including thickening of the plantar fascia, soft-tissue edema, and bone marrow edema, were observed after treatment (P < .05).
Conclusions:
Extracorporeal shockwave therapy is a safe and effective treatment that yields favorable results in improvement of pain and function for plantar fasciitis. An MRI is useful for determining response to ESWT for these patients.
