Introduction:
The objective of this study was to answer the typical questions from patients regarding the likely neurologic outcome and likelihood of recurrence when discussing peroneal intraneural ganglion cysts preoperatively.
Methods:
Retrospective analysis of all patients who underwent surgery for a peroneal intraneural ganglion cyst between January 1, 2000, and April 1, 2017, was performed. Postoperative neurologic outcomes and radiologic recurrences are reported.
Results:
There were 65 patients. Average clinical follow-up was 14 months. Median dorsiflexion and eversion preoperatively were 2/5 and 4/5, respectively. Median dorsiflexion and eversion at last follow-up postoperatively were 5/5. Radiologic recurrence occurred in 6 (9%) patients, all extraneural.
Discussion:
The data support excellent postoperative motor outcomes, despite frequent dense weakness of peroneal-innervated musculature preoperatively. The surgical approach appears to eliminate risk of intraneural recurrence and minimizes risk of extraneural recurrence. Muscle Nerve 57: 989-993, 2018.

Outcomes of Glycolysis
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...
Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
