Evaluation of Fixation Techniques for Metatarsocuneiform Arthrodesis.

First metatarsocuneiform joint arthrodesis has been used in foot and ankle surgery for the treatment of hallux abductovalgus deformity, among other pedal pathologic entities. The goal of the present retrospective study was to compare the fusion rates and complications of an intraplate compression screw fixation, crossing solid core screw fixation, and a single interfragmentary screw with a simple locking plate. All procedures were performed by a single surgeon, and all patients received an identical postoperative protocol. A medical record review was performed of 147 evenly distributed surgical methods. All patients were non-weightbearing by protocol for 4 weeks. The patient covariates included sex, age, nicotine status, osteoporosis, and diabetes. These variables were balanced among the treatment groups and were noncontributory, with the exception of sex. Male patients had a 6 times greater odds of experiencing nonunion. The overall nonunion rate was 6.7%, with 4% symptomatic and requiring revision. The individual nonunion rates for each method were 2% for intraplate compression screw fixation, 5% for single interfragmentary screw with locking plate fixation, and 9% for crossing solid core screw fixation. None of the differences reached statistical significance. The corresponding hardware removal rates were 12%, 11%, and 0%.

Arthroscopic Treatment of Ankle Arthritis.

Ankle arthritis can be broadly classified as primary arthritis (nontraumatic degeneration) or secondary arthritis (post-traumatic degeneration). A good understanding of the anatomic features and presentations associated with each will assist the surgeon in determining the best course of action for each patient. Many variations of both primary and secondary arthritis can be treated conservatively; however, there are many times when conservative therapy is not adequate. In these cases, ankle arthroscopy may be considered before a joint fusion or replacement. Here, the authors discuss the common types of ankle arthritis, their presentations, and treatment success with ankle arthroscopy.

Complications of Tendon Surgery in the Foot and Ankle.

This article discusses four subsets of patients that have an increased risk of complications from tendon surgery in the foot and ankle: smokers, diabetics, and patients with peroneal or Achilles tendon pathology. Very little has been published on the complications of other tendon surgeries in the foot and ankle other than Achilles tendon repair. Data can be extrapolated from the general orthopedic literature and animal studies to help guide therapy and treatment options. The foot and ankle surgeon must take into account the entirety of the history and physical examination to develop a treatment plan that optimizes each patient's chance for a complication-free recovery.

Instrumentation in Arthroscopy.

In recent years, arthroscopic procedures of the foot and ankle have seen a significant increase in both indications and popularity. Furthermore, technological advances in video quality, fluid management, and other arthroscopy-specific instruments continue to make arthroscopic procedures more effective with reproducible outcomes. As surgeons continue to use this approach, it is important that they have a complete understanding of the instrumentation available to them, including their indications and limitations.
