Background: It has been theorized that tibialis posterior tendon dysfunction (TPTD) is a degenerative process unrelated to inflammation. The purpose of this study was to determine if inflammatory cytokines, matrix metalloproteases (MMPs), and glutamate were elevated in diseased tibialis posterior tendons (TPTs).
Methods: Matched diseased TPT, TPT insertion, and flexor digitorum longus (FDL) samples were collected from 21 patients. The samples were individually incubated in media, which was analyzed for inflammatory cytokines, MMPs, and glutamate. Histology and statistical analyses were performed.
Results: Diseased TPT and TPT insertion were significantly elevated compared to transferred FDL in eight inflammatory markers (p < 0.005). Only the diseased TPT was significantly elevated compared to the transferred FDL tendons for glutamate (p < 0.01). Histologic grading correlated with inflammatory cytokine levels.
Conclusion: Diseased TPT and TPT insertion demonstrated significantly elevated levels of inflammatory markers compared to the transferred tendons used as controls, suggesting a role for inflammation in the disease process. The amount of inflammation correlated with increased tendon degradation.
Level Of Evidence: Level III.

Peroneal nerve injury is a common neuropathy that affects the lower extremities. It results in loss of dorsiflexion at the tibiotalar joint and eversion at the subtalar joint, ultimately leading to foot drop. Various etiological factors contribute to this pathology.

Background Context: Total en bloc spondylectomy (TES) for lumbar tumors significantly impacts lower extremity motor function because of surgical stress on the lumbar nerve roots and psoas muscles.
Purpose: The aim of this study was to assess the strength of the major lower extremity muscles and walking function following lumbar TES using prospectively collected data and identify functional differences based on the levels of the resected vertebrae.
Study Design/setting: Retrospective study with prospectively collected data PATIENT SAMPLE: Data were collected from 34 patients who underwent single-level TES for lumbar spinal tumors at our institution between January 2010 and December 2021.

Ultrasound-guided interventions for the ankle and foot offer precise treatment for musculoskeletal conditions. This article reviews injections of the talocrural joint, first metatarsophalangeal joint, Achilles tendon (via stripping and retrocalcaneal bursa injections), plantar aponeurosis, and tibialis posterior tendon, detailing probe selection, patient positioning, and procedural techniques. Precise needle guidance is emphasized to prevent complications like nerve injury and tendon rupture.

Background: This study aimed to investigate how barbell type (elastic vs. inelastic) and lifting speed affect postural stability and lower limb muscle activation during the single-leg deadlift (SLDL), a common unilateral exercise in rehabilitation and performance training.
Methods: Twenty-seven healthy adults performed SLDLs using both elastic and inelastic barbells under three lifting speeds (normal, fast, and power).

Isolated subtalar dislocations constitute 1% of all dislocations and are extremely rare. They frequently occur as a result of high-energy trauma. Dislocations are classified based on the direction of the dislocation, with 80% being medial.
