AI Article Synopsis
- Ultrasonographic measurement of fetal foot length is a reliable method for assessing gestational age, showing strong correlation with existing data.
- A study involved postpartum and ultrasonographic foot length measurements across a range of gestational weeks, filtering for accurate dates and no physical anomalies.
- The research found that fetal foot length measurements could be particularly beneficial in cases where other measurements, like biparietal diameter or femur length, may not be accurate due to certain conditions.
Article Abstract
Ultrasonographic measurement of fetal foot length is useful in the assessment of gestational age. Two hundred twenty-three postpartum and 224 ultrasonographic measurements were performed between 11 and 43 weeks' gestation; 207 postpartum and 160 ultrasonographic measurements met our requirements of secure dates and no physical anomaly or maternal disease. Mean foot length at each week of gestation compared favorably with Streeter's data, based on pathologic specimens, described in 1920. Comparison of curvilinear regression of foot length versus gestational age demonstrated a strong correlation with an R2 value of 0.981; 95% confidence intervals at each week compared favorably with both biparietal diameter and femur length data. Fetal foot length is a reliable parameter for use in the assessment of gestational age and is particularly useful when other parameters do not accurately predict gestational age, for example, hydrocephalus, anencephaly, short limb dysplasia.

Endoscopic Flexor Hallucis Longus Tendon Transfer for the Treatment of Chronic Achilles Tendon Defects.
JBJS Essent Surg Tech
January 2025
The Ohio State University College of Medicine, Columbus, Ohio.
Background: An all-inside endoscopic flexor hallucis longus (FHL) tendon transfer is indicated for the treatment of chronic, full-thickness Achilles tendon defects. The aim of this procedure is to restore function of the gastrocnemius-soleus complex while avoiding the wound complications associated with open procedures.
Description: This procedure can be performed through 2 endoscopic portals, a posteromedial portal (the working portal) and a posterolateral portal (the visualization portal).
Optimizing Physical Assessment in Intrathecal Baclofen Screening Trials for High-Performing Patients With Spastic Paraparesis.

Department of Neurology, Graduate School of Medicine, Chiba University, Chiba, Japan.
Objectives: Intrathecal baclofen (ITB) therapy is well documented as an effective treatment option for severe spasticity. Before ITB implantation, trials are conducted to evaluate efficacy, safety, and candidate suitability. While many centers conduct ITB trials, appropriate physical assessment has not been fully established.

Department of Orthopedic Surgery, Hallym University Dongtan Sacred Heart Hospital, Hwaseong 18450, Republic of Korea.
: Hallux valgus is a prevalent foot deformity conventionally treated with open surgical techniques, which carry risk of complications due to extensive soft tissue dissection. Minimally invasive surgeries (MISs) as alternatives offer comparable outcomes, reduced pain, and faster recovery; however, their challenges include the risk of shortening of the first metatarsal. This study aimed to assess the efficacy of our modified MIS hallux valgus correction technique and investigate the factors that affect first metatarsal shortening.

Background: Charcot-Marie-Tooth (CMT) is a progressive disease resulting in distal sensory deficit and muscular weakness. As the disease progresses, most children develop a cavovarus foot deformity. Foot orthoses (FO) are widely prescribed in CMT to support the foot and improve gait, but there is a lack of guidelines for their conception.
