To perform the test, one hand should stabilize the metacarpal neck while the other grasps the proximal phalanx and controls rotation, because rotation of the phalanx can masquerade as valgus laxity (Fig.
stated.[26] In our study, among these Stener lesions, there were five cases with rupture of UCL at the insertion into the proximal phalanx, which confirmed the statement that in most cases of UCL injuries, most of them occurred at the distal insertion.[17] We assumed that the main reason was the insertion of the UCL which located in the base of the proximal phalanx increased the possibility of injury when the thumb was hyperabducted.
Plain radiography showed that the angle between the proximal growth plate and the distal articular surface of the proximal phalanx was 15.3[degrees] on the affected side compared with 4.7[degrees] on the contralateral noninjured side (Figure 7).
The translational stiffness values are lower in comparison with those obtained by other researchers (e.g., [3, 19, 20]), and the damping is also lower for the distal and middle phalanx and comparable for the proximal phalanx. The reason for different value ranges is mainly due to the scale of the finger-measurements data that were used for the modeling.
(19) They reported the results of 12 unstable extra-articular fractures of the proximal phalanx treated with the intramedullary K-wires.
(2) Open fractures of the proximal phalanx are a surgical emergency and immediate orthopedic consultation is recommended to reduce complications, particularly infection.

With a #11 blade the adductor tendon is sharply released from its attachments to the base of the proximal phalanx and the lateral aspect of the fibular sesamoid (Fig 2).
He was a multiple-injured case with closed fractures of femoral shaft and proximal phalanx of left second finger.
It is only on the lateral view that the astute clinician will see the dorsally displaced proximal phalanx on the metacarpal head.
Radiography of the feet revealed soft-tissue syndactyly of the 2nd and 3rd toes bilaterally and a bone island on the proximal phalanx of the big toe (Fig.
