To analyze the effect of lower-limb rotation on foot pressure distribution, 16 patients (23 feet) with neuromuscular diseases who received derotation osteotomy of lower limbs without concomitant foot-ankle procedures were included in this retrospective study. The cross-correlation analysis showed that the interval change of the foot progression angle was correlated with the interval change of the medial-lateral foot pressure impulse distribution. The externally rotated foot progression angle tends to introduce higher loading on the medial foot, and the internally rotated foot progression angle shifts the loading to lateral side of the foot. This study provides evidence that the rotational profile of the lower limb has a substantial impact on foot pressure distribution.

Background: Few studies reported the long-term clinical outcomes and joint degeneration of patients with chronic lateral ankle instability (CLAI) and small osteochondral lesions of the talus (OLTs) following simultaneous open modified Broström-Gould (MBG) surgery and arthroscopic bone marrow stimulation (BMS). The purpose of this study was to study the long-term results of patients after BMS and BMG surgery, and to further evaluate the potential effect of OLT size on postoperative results.
Methods: In this retrospective study, 110 CLAI patients were divided into 57 patients with OLTs (including 24 patients having combined small osteochondral lesions of the tibial plafond) receiving simultaneous BMS and MBG surgeries (BMS+MBG group), and 53 patients without OLTs receiving isolated open MBG surgery (MBG group).

Exosomes, small extracellular vesicles secreted by various cells, play crucial roles in the pathogenesis and treatment of oral diseases. Recent studies have highlighted their involvement in orthodontics, periodontitis, oral squamous cell carcinoma (OSCC), and hand, foot, and mouth disease (HFMD). Exosomes have a positive effect on the inflammatory environment of the oral cavity, remodeling and regeneration of oral tissues, and offer promising therapeutic options for bone and periodontal tissue restoration.

Introduction: Musculocontractural Ehlers-Danlos syndrome (mcEDS) is a rare autosomal recessive connective tissue disorder caused by systemic depletion of dermatan sulfate. Symptoms characteristic of mcEDS include multiple contractures, fragile skin with subcutaneous bleeding, and hypermobile joints, which suggest difficulty in perioperative management. However, safe surgical techniques and perioperative management of this disorder remain unknown because of its rarity.

Background: Calcaneal fracture malunion (CFM) commonly occurs with multiple pathologic changes and progressive pain and difficulty walking. The purpose of this study was to propose a modified 3-plane joint-preserving osteotomy for the treatment of CFM with subtalar joint incongruence, and to compare its efficacy to subtalar arthrodesis.
Methods: A retrospective comparative analysis of the data of 56 patients with CFM admitted from January 2017 to December 2022 was performed.
