As hallux valgus (HV) worsens clinical and radiological signs of arthritis develop in metatarsophalangeal joint due to incongruity of joint surfaces. The purpose of this prospective study was to determine if intraoperative mapping of articular erosion of the first metatarsal head, base of the proximal phalanx, and tibial and fibular sesamoids can be correlated to clinical and/or radiographic parameters used during the preoperative assessment of the HV deformity We analysed 50 patients prospectively who underwent surgery between Jan 2009-Jan 2010. Patients with a known history of previous first metatarsophalangeal joint surgical intervention, trauma, or systemic arthritis were excluded from analysis. Preoperative demographics and AOFAS score were recorded. Intraoperative evaluation and quantification of the first metatarsal head, base of the proximal phalanx, and sesamoid articular cartilage erosion was performed. Cartilage wear was documented using International Cartilage Research Society grading.Background
