BACKGROUND: Patients with moderate to severe hallux valgus (HV) sometimes exhibit second metatarsophalangeal (MTP) joint dislocation. Second MTP joint instability due to plantar plate (PP) injury has been suggested as one of the causes. However, there have been no reports that quantitatively evaluate this instability. This study aimed to evaluate second MTP joint instability in patients with HV without dislocation via ultrasonography and investigate its relationship with the presence of PP injury or foot form. METHODS: Between May 2018 and July 2023, symptomatic female patients with HV without any lesser toe deformity were included in this study. Second MTP joint instability was defined as the dorsal displacement ratio (DDR) of the passively subluxated proximal phalangeal articular surface on the metatarsal head articular surface. The presence of PP injury was assessed using ultrasonography. Foot "form" was determined by measuring standard foot bony angles on weight-bearing foot-ankle radiographs. The relationship between DDR or PP injury and radiographic measurements was investigated. RESULTS: Sixty-four patients (100 feet) were included. The average DDR of the second MTP joint in patients with HV without dislocation was 35.7%. There was an increase in the probability of PP injury, above a cutoff DDR value r of 35.4% (area under the curve = 0.712). The sensitivity, specificity, positive predictive value, and negative predictive value for the presence of PP injury based on this cutoff level were 63.9%, 74.4%, 79.6%, and 56.9%, respectively. Metatarsalgia was reported in 21 feet (21.0%), of which 15 feet (71.4%) showed PP injury. An increase in DDR was weakly associated with increased metatarsus adductus angle and decreased second metatarsal height. CONCLUSION: In female patients with HV without second MTP dislocation, we found ultrasonographic evidence of second MTP plantar plate injury and joint instability to be a relatively common finding with a high prevalence in those with localized metatarsalgia. LEVEL OF EVIDENCE: Level II, development of diagnostic criteria based on consecutive patients.

BACKGROUND: Mastectomy has been the standard surgical treatment for ipsilateral breast tumor recurrence (IBTR). Recently, there has been growing interest in repeat breast-conserving surgery (rBCS) for IBTR among breast surgeons; however, there is currently little information regarding patient preferences for surgical procedure for IBTR. The purpose of this study was to evaluate preference for surgical procedure (mastectomy vs. rBCS) among breast cancer patients who had undergone salvage surgery for IBTR. METHODS: Overall, 100 breast cancer patients who had undergone salvage surgery for IBTR were asked about their preferred surgical methods for IBTR and the reason. The association of patient preference and the reasons related to various clinical and pathological factors were assessed. RESULTS: Of the 100 respondents, only 11 patients (11%) preferred rBCS. Patients who had undergone rBCS and radiotherapy for IBTR were significantly more likely to prefer to undergo rBCS than other groups (p = 0.030). The most frequent reason for choosing rBCS was the patient's desire to minimize breast deformity and surgical wounds. CONCLUSIONS: Our study revealed that there is a low rate of patients who opt to undergo rBCS among patients who had undergone salvage surgery for IBTR. Discrepancies in perceptions regarding the surgical procedure for IBTR between patients and their surgeons may exist.
