Hallux Valgus Nonunion Correction in an Active Duty Military Member.

Hallux valgus is one of the most common conditions treated by foot and ankle orthopedists; over 140 surgical procedures have been developed for management of the condition. A rare complication of hallux valgus repair is nonunion, and the literature regarding nonunion after hallux valgus repair is correspondingly sparse. We present a 39-year-old active duty male who underwent operative management after developing nonunion and transfer metatarsalgia following a proximal oblique metatarsal osteotomy. The patient underwent nonunion correction and metatarsal lengthening via bone allografting. No complications were observed during the intra- or perioperative periods. At 2.5-years postoperatively, the patient's symptoms had largely resolved. He expressed high satisfaction with his outcome and was able to continue activity duty. Our findings indicate that nonunion repair can have excellent clinical outcomes with high patient satisfaction, even in an active military population.

Unilateral Dislocation of the Posterior Tibialis Tendon (PTT) and Flexor Digitorum Longus Tendon With Contralateral PTT Subluxation in a Patient With Congenitally Shallow Flexor Groove.

INTRODUCTION: Flexor tendon dislocation from the flexor tendon groove posterior of the medial malleolus has been previously described, and may be difficult to diagnose initially, but is amendable to surgical treatment with good outcomes. We present a unique case of unilateral dislocation of the posterior tibialis and flexor digitorum longus tendons with contralateral flexor digitorum longus subluxation that was treated surgically with a good outcome. CASE PRESENTATION: A 37-year-old active duty male sustained a dislocation and subluxation of the flexor tendons bilaterally after a forced dorsiflexion injury. Bilateral ankle magnetic resonance imaging revealed the injuries that this patient sustained and aided in surgical planning. Surgical Treatment. Bilateral flexor tendon groove deepening with periosteal flap elevation and retinacular repair. DISCUSSION/CONCLUSION: This injury has not been previously described in the literature after a forced dorsiflexion mechanism. Advanced imaging is helpful as this injury may be initially misdiagnosed. This case shows that delayed bilateral reconstruction of the flexor tendon grooves and retinacula are reliable methods for pain relief to allow a patient to return to a physically demanding level of function. LEVELS OF EVIDENCE: Level V.

Current thoughts on ankle arthritis.

The ankle is the most commonly injured joint in athletic and work activities. In contrast, osteoarthritis of the ankle joint is relatively rare and is typically post-traumatic or inflammatory in nature. Common symptoms that prompt an orthopaedic consultation include pain, disability and altered gait mechanics. Non-operative management has been the mainstay for previously undiagnosed patients. For those with advanced disease, ankle fusion or total ankle replacement may be the only surgical options. Though some recent studies have shown patients' preference for a well functioning ankle replacement, significant long- term follow-up data is lacking.

Diagnosis and management of lisfranc injuries and metatarsal fractures.

Forefoot and midfoot injuries are relatively common and can lead to chronic disability, especially if they are not promptly diagnosed and appropriately treated. A focused history and physical examination must be coupled with a thorough review of imaging studies to identify the correct diagnosis. Subtle radiographic changes can represent significant ligamentous Lisfranc injury. Midfoot swelling in the presence of plantar ecchymosis should be considered to be a Lisfranc injury until proven otherwise. While most metatarsal fractures can be treated with some form of immobilization and protected weight-bearing, this article will distinguish these more common injuries from those requiring surgical intervention. We will review relevant anatomy and biomechanics, mechanisms of injury, clinical presentation, imaging studies, and diagnostic techniques and treatment.

Case report: Bowel perforation presenting as subcutaneous emphysema of the thigh.

Necrotizing fasciitis is recognized as a surgical emergency. Early detection and aggressive surgical débridement are crucial to reduce patient mortality and morbidity. There are, however, other causes of subcutaneous emphysema. We present the case of a 64 year-old patient with a history of postsurgical radiation for rectal carcinoma with subcutaneous emphysema of the thigh in the presence of urinary sepsis. Surgical exploration revealed the source of the emphysema to be an enterocutaneous fistula. The patient had an unstable and prolonged hospitalization after débridements of the thigh and abdominal surgery and was readmitted for recurrence of thigh drainage, but eventually was discharged; nine months after the initial diagnosis all wounds had healed and he was walking with a walker. Despite an otherwise benign clinical appearance, the radiographic finding of subcutaneous emphysema in the absence of penetrating trauma must be considered a case of a necrotizing soft tissue infection until proven otherwise.
