Midfoot Fusion Using Superconstructs for the Charcot Foot: Current Techniques and Complications.

Neuroarthropathy of the foot and ankle presents a series of challenges. The treating physician faces a perfect storm of pathomechanics, deformity, and medical comorbidities. Successful treatment requires a systematic approach in diagnosis, nonsurgical management, surgical management, and long-term maintenance of the affected extremity. Nonsurgical care of the Charcot foot remains the mainstay of treatment and is successful in most cases. Surgery has become more accepted for patients with severe deformity. The concept of a superconstruct has been introduced to describe modern surgical techniques and implants that have been developed since the early 2000s where stability and durability are maximized. A superconstruct is defined by four factors: (1) fusion is extended beyond the zone of injury to bridge the area of bony dissolution; (2) aggressive bone resection is performed to allow for adequate reduction of deformity without undue tension on the soft-tissue envelope; (3) stronger implants are used than for nonneuropathic fusion procedures, including some specifically developed for fixation of the Charcot foot; and (4) the devices are applied in a position that maximizes mechanical stability to allow the implants to become load sharing. It is important to review the current techniques and implants used in fusion of the neuropathic midfoot and discuss the expected outcomes and complications based on the authors' experience.

Management of Acute Ankle Fractures in Patients With Diabetes.

Ankle fractures in patients with diabetes can be difficult to manage, especially when patients present with hyperglycemia. Treatment often requires a combination of both medical and surgical care, especially in patients with poorly controlled diabetes. The goal of any treatment is to obtain a well-aligned ankle fracture that heals without any further displacement and to avoid the development of a Charcot joint. Nonsurgical treatment is usually reserved for nondisplaced fractures. Displaced fractures often require surgical treatment, and there are different options available, including standard fixation, fixation with multiple syndesmotic screw placement, external (thin wire) fixation alone, hybrid or combined internal and external fixation techniques, and primary arthrodesis. It is important to discuss the approach to the evaluation and treatment of these patients.

Charcot foot: a surgical algorithm.

The historic treatment of Charcot foot has entailed non-weight-bearing immobilization during the acute active phase, followed by longitudinal management with accommodative bracing. This treatment plan yields poor outcomes, even in cases classified as successful. An appreciation of poor outcomes convinced experts to attempt correction of the resultant deformities. Early attempts at surgical correction of the acquired deformities in patients with medical comorbidities were complicated by infection, wound failure, and mechanical loss of correction. New surgical techniques have been designed to obtain and maintain correction and minimize the risks for complications and poor outcomes in this complex patient population.

Lasso stitch with peroneal retinaculoplasty for repair of fractured os peroneum: a report of two cases.

UNLABELLED: Fracture of the os peroneus with retraction of the peroneus longus tendon can lead to weakness, instability, and progressive foot deformity. Treatment recommendations vary and include simple immobilization, repair of the fractured ossicle, excision of part or all of the fractured ossicle with repair of the tendon and tenodesis with the peroneus brevis tendon. We present two patients treated with excision of the proximal fragment and repair of the tendon to the distal fragment with relief of pain and restoration of function. The distal fragment was captured with a looped suture which allowed avoidance of a plantar exposure while still achieving an adequate repair. We also describe a technique for retinaculoplasty of the inferior peroneal retinaculum which we believe important to prevent postoperative adhesions to the tendon.

Peroneal tendoscopy: indications and techniques.

Endoscopy of the tendons (tendoscopy) of the foot and ankle has become more frequently performed and reported. New, smaller endoscopic cameras and instruments have made tendoscopy more accessible and useful for sports medicine and related surgeries. The peroneal tendons are particularly accessible for tendoscopy owing to their subcutaneous position along the lateral ankle. Tendoscopy of the peroneal tendon sheaths can be used for diagnosis and minimally invasive treatment of certain disorders. In cases where open procedures are indicated, surgical exposure can be limited by tendoscopic identification of the exact location of the pathology, allowing repair through a limited or "mini" incision. This paper reviews the available literature and presents the authors technique for peroneal tendoscopy. Endoscopic photographs of normal anatomy and pathologic conditions are presented.

Ankle arthrodesis in rheumatoid arthritis: techniques, results, and complications.

This article defines specific risks associated with rheumatoid arthritis, including an increased incidence of medical comorbidities, the use of steroids and other immunosuppressive agents, osteoporosis, vascular disease, and the common occurrence of severe deformity. This article suggests approaches for management and techniques that may improve specific surgical issues in this challenging patient population.
