Introduction: Chondrosarcoma (CHS) of the toes is very rare and the involvement of phalanges is extremely rare. The osteolytic destruction of this tumor severely affects limb function and carries the risk of distant metastasis. These tumors are removed surgically to minimize local recurrence and distant metastases, maximize limb function with better prognosis. The main objective of this report is to present the case of a CHS that invaded the phalanx of the left great toe and formed a large phalangeal mass with osteolytic destruction of the distal bone.
Case Report: This case report includes a 60-year-old man suffering from swelling of his left great toe for 2 years, with pain and swelling for 6 months. Serial hematological, radiological and tumor investigations were done. Magnetic resonance imaging revealed a well-defined peripherally enhancing multilobulated soft-tissue mass with central necrotic component involving the entire proximal phalanx of left great toe extending to distal phalanx and head of first metatarsal. The patient was planned for operative intervention due to the possibility of invasion into the adjacent bones. The tumor was excised and sent for histopathological examination, which was reported as Grade 2 CHS (PT, Nx, and Mx) and was S100 positive. The patient has been followed-up for 5 months.
Results: There were no signs of local recurrence or distant metastasis on radiological investigations or clinical assessment during follow-ups.
Conclusion: CHS occurring in toes is extremely rare. In this case, extensive surgical resection of the large low-grade CHS was safe and effective.

Background: Hallux valgus (HV) is the most prevalent foot condition, associated with a decline in quality of life and a high rate of complications. Pedobarography can be a diagnostic tool, although controversies exist due to differences in measurement scales, type of capture, software, and hardware used. Deformity level differences have not been thoroughly explored.

This study presents the longest systematic prospective follow-up of spinal cord disease in adult male ALD patients to date. Standardized yearly quantitative data collection included scoring of the EDSS, SSPROM, 6-min walking test (6MWT), urological and quality of life questionnaires and vibration sense of the hallux. Progression rates were compared between patients with mild (EDSS ≤ 2.

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).

Background: This study aimed to (1) determine the association between varus knee deformity and ipsilateral foot and ankle morphology, and (2) evaluate the relationship between varus knee deformity and foot and ankle pain in patients with end-stage varus knee osteoarthritis (KOA).
Methods: A total of 213 patients who underwent primary total knee arthroplasty for end-stage varus KOA were enrolled in this study and divided into a 'severe varus group' (n = 119) and a 'mild varus group' (n = 94) based on preoperative knee varus degree. Morphological parameters and pain incidence in the foot and ankle were compared between the two groups.

Patients with diabetes polyneuropathy are at a heightened risk for developing foot ulcers, often due to dynamic plantar foot pressure patterns that lead to increased pressure and shear forces in specific foot areas. This study aimed to evaluate the effects of foot insoles on peak pressure and the pressure-time integral in patients with polyneuropathy diabetic foot ulcers over a twelve-week period followed by an eight-week follow up. : This was a prospective, randomized, double-blinded, controlled clinical trial involving 60 patients aged between 50 and 65 years of both genders.
