Length of the forearm, length of the PL muscle tendon and the length of the RCE muscle tendons and their radial half, by sex (in mm and with radial deviation
(beyond 48.6[degrees] of flexion, 32.7[degrees] of extension, 21.8[degrees] of radial deviation
, or 14.5[degrees] of ulnar deviation) have been operationally defined as extreme or exceeding the limits of the neutral range of wrist orientations .
The continued growth of ulna and stunted radial growth has resulted in radial deviation
of the wrist and the hand (Figures 9 & 10).
In the XCSR group, in comparison with the contralateral wrist, the following values were achieved: volar flexion, 82.5%; dorsal flexion, 82.0%; radial deviation
, 85.7%; ulnar deviation, 61.3%; pronation, 92.6%; supination, 88.8 % and grip strength, 73.8%.

(3), (4) Thus, patients with a PIN lesion still may be able to extend their wrists, but only weakly, with a radial deviation
. This is due to the relative preservation of the extensor carpi radialis longus (ECRL) along with a non-functional extensor carpi ulnaris (ECU) that is dynamically not balancing the action of the functioning ECRL and extensor carpi radialis brevis (ECRB) muscles.
Deformity needs to be differentiated from other similar deformities such as clinodactyly (radial deviation
at the DIP joint) and camptodactyly (flexion deformity at the PIP joint).
Active wrist ROM revealed discomfort at end ranges of flexion, extension, and radial deviation
. Ulnar deviation as well as active thumb extension and abduction movements were limited by 50%.
Upper extremity examination reve aled radial deviation
of both wrist with ulnar deviation of the finger ("Z" deformation) and swan-neck deformities of the fingers of both hands (Fig.

Patient was treated by reduction under general anaesthesia done by forcible flexion, radial deviation
of the wrist along with simultaneous milking of the pisiform bone back into its anatomical position.
