Isolate fracture of lunate is very rare. The authors reported a neglected fracture of lunate which was founded incidentally after the dorsal wall fracture of triquetrum. Pain reduction and improvement of range of motion was achieved after excising the dorsal fragment of lunate.

OBJECTIVE: To compare optical motion capture system (MoCap), attitude and heading reference system (AHRS) sensor, and Microsoft Kinect for the continuous measurement of cervical range of motion (ROM). METHODS: Fifteen healthy adult subjects were asked to sit in front of the Kinect camera with optical markers and AHRS sensors attached to the body in a room equipped with optical motion capture camera. Subjects were instructed to independently perform axial rotation followed by flexion/extension and lateral bending. Each movement was repeated 5 times while being measured simultaneously with 3 devices. Using the MoCap system as the gold standard, the validity of AHRS and Kinect for measurement of cervical ROM was assessed by calculating correlation coefficient and Bland–Altman plot with 95% limits of agreement (LoA). RESULTS: MoCap and ARHS showed fair agreement (95% LoA<10°), while MoCap and Kinect showed less favorable agreement (95% LoA>10°) for measuring ROM in all directions. Intraclass correlation coefficient (ICC) values between MoCap and AHRS in –40° to 40° range were excellent for flexion/extension and lateral bending (ICC>0.9). ICC values were also fair for axial rotation (ICC>0.8). ICC values between MoCap and Kinect system in –40° to 40° range were fair for all motions. CONCLUSION: Our study showed feasibility of using AHRS to measure cervical ROM during continuous motion with an acceptable range of error. AHRS and Kinect system can also be used for continuous monitoring of flexion/extension and lateral bending in ordinary range.

In recent years, the sense of equilibrium began to receive a significant attention due to serious motion sickness derived from a high speed and frequency vehicles with the development of civilization. In aerospace age, many studies have been in progress about the equilibrium and spatial orientation under weightless conditions. This article focused on explaining vestibular anatomy and physiology. Furthermore, we tried to put the accent on introducing the role of vestibular system that is responsible for equilibrium of the body in spatial orientation.
