Background: This study aimed to evaluate the outcomes of ankle fractures with posterior malleolus fragments (PMFs) involving <25% of the articular surface treated with or without screw fixation. Methods: Among patients with ankle fractures and PMFs who underwent surgery between March 2014 and February 2017, 62 with type 1 PMFs involving <25% of the articular surface were included. Of these 62 patients, 32 underwent screw fixation for PMFs and lateral and/or medial malleolar fracture fixation (group A) and 30 underwent internal fixation for malleolar fractures without screw fixation for PMFs (group B). Ankle joint alignment and fracture healing were measured using plain radiography and computed tomography (CT). Clinical outcomes were determined using the American Academy of Orthopaedic Surgeons Foot and Ankle Questionnaire, Short Form-36, and American Orthopaedic Foot & Ankle Society Scale. Results: Nonunion was not noted in either group. However, we detected union with a step-off of 2 mm or more in 2 cases from group B. With regard to ankle joint alignment, 1 case in group A and 3 cases in group B showed mild asymmetry of the medial and lateral clear spaces on CT at 12 months. Clinical outcomes at 6 and 12 months after surgery were better in group A than in group B. Conclusion: Screw fixation of PMFs was effective for fracture healing and maintaining ankle alignment. Additionally, it improved short-term clinical outcomes, which we believe was due to stabilization of ankle fractures with PMFs involving <25% of the articular surface. Level of Evidence: Level II, prospective comparative study.

Background: We compared the radiographic results and clinical outcomes of patients operated on via the extended sinus tarsi approach (ESTA) and the extended lateral approach (ELA) for treatment of displaced intraarticular calcaneal fractures. Methods: We retrospectively studied the utility of the ELA (46 patients, 52 feet) and the ESTA (56 patients, 64 feet) in patients operated on between January 2009 and March 2015. We evaluated pre- and postoperative x-rays and computed tomography (CT) data. Pain, patient-reported functional outcomes, satisfaction, and postoperative complications were investigated at the 3-year follow-up. Results: Neither the postoperative nor 3-year follow-up Böhler angles, nor the calcaneal width, differed significantly between the 2 groups (both P > .05). However, the maximum step-off of the posterior facet on the 3-month CT follow-up of the ESTA group was significantly less than that of the ELA group ( P < .05). We found no significant between-group differences in terms of postoperative translation ( P = .232) or angulation ( P = .132) of the sustentacular fragment on the 3-month CT follow-up. At the 3-year follow-up, we found no significant between-group difference in the mean visual analog scale pain score at rest ( P = .641) or during weightbearing ( P = .525). We found no significant between-group difference in the Foot Function Index (FFI) ( P = .712) or self-reported satisfaction ( P = .823). The ELA group experienced significantly more wound complications ( P = .041) and nonunions ( P = .041) than the ESTA group. Four instances of superficial peroneal nerve injury were reported in the ESTA group ( P = .127). Conclusion: Compared with the ELA, the ESTA afforded comparable, favorable radiological results and clinical outcomes, associated with fewer wound complications and nonunions. We suggest that the ESTA is an effective operative option when treating displaced, intraarticular calcaneal fractures. Level of Evidence: Level III, comparative study.

We compared the radiographic and clinical outcomes of moderate and severe hallux valgus treated by extended distal chevron osteotomy (EDCO) and distal soft tissue release (DSTR). We performed a retrospective analysis comparing the utility of EDCO for the treatment of moderate (36 patients, 46 feet) and severe (36 patients, 42 feet) hallux valgus. The radiologic outcomes were evaluated based on the preoperative and 3-year follow-up x-rays. The clinical results were investigated based on the 3-year follow-up Manchester-Oxford Foot Questionnaire (MOXFQ), patient satisfaction, and postoperative complications. The mean postoperative intermetatarsal angle, hallux valgus angle, tibial sesamoid position, and relative metatarsal bone length were significantly different compared with the preoperative values for both the moderate and severe groups (P < .001). At 3-year follow-up, intergroup differences were observed in the mean postoperative intermetatarsal angle (P = .001), hallux valgus angle (P = .003), and tibial sesamoid position (P = .013); however, mean radiographic results were within the normal range for both groups. There were no intergroup differences for either the first metatarsal bone length (P = .172) or shortening (P = .621). No significant difference in MOXFQ (P = .525) was evident between the groups at 3-year follow-up. In satisfaction analysis, 82.6% of the moderate group reported good to excellent results, as did 81.0% of the severe group (P = .815). A total of 7 complications were reported in each group (P = 1.000). The present study showed that midterm mean radiographic results of both moderate and severe hallux valgus treated by EDCO with DSTR were favorable, and those values were within the normal range. Clinical outcomes were comparable between the 2 groups, including overall efficacy. Based on these results, we recommend EDCO with DSTR as an efficient and reliable operative option for both moderate and severe hallux valgus. Level III, retrospective comparative study.
