ABSTRACT
Background@#Radiological correction of hallux valgus deformity is the objective of operation and related to successful outcomes. Nonetheless, footwear problems related to foot width can also affect the clinical outcome. Few studies have analyzed changes in foot width, and data on clinical outcomes after correction of hallux valgus deformity are scarce. @*Methods@#The study included 159 cases with symptomatic hallux valgus deformity who underwent proximal or distal chevron metatarsal osteotomy and were followed up for a mean of 32.8 months. Radiologically, the hallux valgus angle, intermetatarsal angle, first metatarsal head width, bony foot width, and soft-tissue foot width were analyzed. Clinically, the visual analog scale for pain and American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal score were evaluated. @*Results@#The preoperative hallux valgus was corrected radiologically at the last follow-up. The bony foot width was reduced by 9.4%, and the soft-tissue foot width was reduced by 7.1% (p < 0.001 for all). The mean AOFAS score improved from 51.2 preoperatively to 89.4 at the final follow-up (p < 0.001). In multiple regression, the perioperative changes of bony foot width were associated with final AOFAS score (p = 0.029). @*Conclusions@#Chevron osteotomy performed for hallux valgus deformity resulted in satisfactory radiological and clinical outcomes.Perioperative changes in bony foot width showed a significant correlation with AOFAS score. Therefore, to correct hallux valgus deformity, it is necessary to correct known radiological indicators sufficiently and make efforts simultaneously to reduce the foot width optimally.
ABSTRACT
The Lisfranc joint complex is composed of complex bony structures, ligaments, and soft tissues and has a systematic interrelationship. Sufficient radiologic modalities should be considered for an accurate initial diagnosis. Based on an accurate understanding of normal anatomy and restoration of anatomical relationships, the diagnosis should be obtained, and more discussion is needed on detailed treatment strategies.
ABSTRACT
Syndesmotic injuries are found frequently in clinical practice, and they remain controversial because of the variety of diagnostic techniques and management options. Bony avulsions or malleolar fractures are commonly associated with syndesmotic disruptions. Even unstable isolated syndesmosis injuries are associated with a latent or frank tibiofibular diastasis and should not be ignored in the early phase. A relevant instability of the syndesmosis with diastasis results from collateral ligaments tears and requires operative stabilization.The treatment involves an anatomic reduction of the distal tibiofibular articulations followed by stable fixation. Syndesmotic transfixation screws or suture button implants are being proposed as a means of fixation. Recently, suture button fixation has shown more favorable outcomes, but the outcomes can still be controversial. Syndesmotic malreduction can lead to hardware failure, adhesions, heterotopic ossification, tibiofibular synostosis, chronic instability, and posttraumatic arthritis. In particular, the correct diagnosis and evidencebased treatment options for unstable syndesmotic injury should be considered.
ABSTRACT
A checkrein deformity can occur after a distal tibiofibular fracture. Usually, a checkrein deformity due to a dysfunction of the extensor hallucis longus muscle is rarer than that of the flexor hallucis longus. Only a few related studies have been reported. The authors encountered an extensor hallucis longus checkrein deformity due to extensor retinaculum syndrome while managing a triplane fracture. In magnetic resonance imaging, an increase in the heterogeneous signal was observed on the T2-weighted images suggesting muscle necrosis or ischemic changes in a part of the extensor hallucis muscle. Postoperative great toe motor weakness, unintentional movement, sensory changes, and weakness improved spontaneously during the follow-up.

ABSTRACT
Tarsal coalition is an abnormal union between two or more bones of the hind- and mid-feet, which can occur at various rates from cartilaginous to osseous union. Talonavicular coalition is reported less frequently than calcaneonavicular or talocalcaneal coalition and has been associated with various abnormalities, including symphalangism, clinodactyly, ray anomaly, clubfoot, other tarsal coalitions, and a ball-and-socket ankle joint. Patients with talonavicular coalitions are usually asymptomatic and rarely require surgical treatment. We review the literature and report on a case of 59-year-old male patient with talonavicular coalition.

Prostaglandin E1 (PGE-1) is a potent vasodilator, which also inhibits platelet aggregation, affects the blood flow viscosity, and fibrinolysis. The compound also excerts anti-inflammatory effects by inhibiting the monocyte and neutrophil function. PGE-1 has been widely administered following microvascular flap surgery, along with perioperative antithrombotic agents such as low molecular weight heparin or aspirin, showing excellent results. We report a case showing successful salvage recovery from post-traumatic ischemic necrosis of the finger via PGE-1 assisted conservative treatment.

The calcaneal insufficiency avulsion fracture usually occurs in an area of fused apophysis in adults without significant history of trauma or overuse activities. It is an uncommon injury which has been described in patients with complicated diabetes, Charcot neuroarthropathy, amyloidosis with neuropathy, severe osteoporosis, and other conditions. Discussion of the issue of fracture location is still not sufficient. We report on a case of a 50-year-old male who experienced a non-traumatic diabetic calcaneal insufficiency fracture. Intraoperatively, a biopsy specimen was obtained from the exposed fracture site for histological study. We assume that the calcaneal fused apophyseal line is the weak point of failure due to various incomplete mixtures of trabecular bone, woven bone, and cartilaginous tissues, and may fail when repeated tensile stress is imposed.
