INTRODUCTION: After laminoplasty, difficulties with neck mobility often interfere with patients' activities of daily living (ADL). Although it has been reported that the flexion-extension range of motion significantly decreased after laminoplasty, in many studies using radiographs there were few patient-based outcomes. The purpose of this study was to reveal the frequency, severity and factors related to limitations of ADL accompanying neck mobility after laminoplasty. MATERIALS AND METHODS: A total of 58 patients were evaluated after laminoplasty to determine the frequency, severity and pre- and postoperative related factors of postoperative limitations of ADL accompanying each of three neck movements: (1) extension, (2) flexion and (3) rotation. The severity of limitations of each ADL was assessed using a questionnaire that was completed by the patient. RESULTS: Difficulties in neck movement, such as rotation (41%), extension (34%) and flexion (17%), in that order (P = 0.001), caused limitations of ADL. The most relevant factor of limitations of ADL accompanying extension, flexion, and rotation were small postoperative O-C7 range of motion (P = 0.0001), small preoperative O-C7 range of motion (P = 0.001), and small postoperative rotation range of motion (P = 0.0005), respectively. CONCLUSION: There were more than a few patients with limitations of ADL accompanying reduced neck mobility after laminoplasty. This knowledge may be useful in the clinical outcomes of cervical laminoplasty.
