The limited bone resection (only the proximal phalanx
or only metatarsal head resection) and lack of detailed information about the localization of internal amputations in their study represent a major difference from our study.
Although it does not insert into the proximal phalanx
, it is able to dorsiflex the proximal phalanx
of the MTP joint through this aponeurotic band, which goes around the MTP joint and is inserted onto the plantar plate.
Of the 21 patients, eighteen were male and three females of which 10 were proximal phalanx
fracture and 11 were metacarpal fracture (4-4th metacarpal, 4-3rd metacarpal, 3-2nd metacarpal) (Table 2).
Surgical treatment involved en bloc resection of the affected metacarpal with a portion of the proximal phalanx
of the thumb and the entire trapezium in order to obtain negative margins.
A fracture extending from the medial cortex of the metaphysis at the base of the second proximal phalanx
into the adjacent physis was noted.
Caption: Figure 1 Thumb amputations distal to the mid-portion of the proximal phalanx
typically function well.
The abductor digiti minimi manus (ADMM) muscle attaches proximally to the pisiform and distally to the proximal phalanx
of the little finger.
On the other hand, ultrasonography showed erosion of the proximal phalanx
The proximal phalanx
is short and stout, very close to the range of metrics reported for E.
The pulley at the MCP joint can move independently from the proximal phalanx
6b-d); 74673, fragment of proximal phalanx
1 of digit III; 74674, fragment of distal phalanx 1 of digit III; 74675, phalanx 2 of digit III (Fig.
Applying an adduction stress to the proximal phalanx
of the great toe will enhance the visualization of the adductor tendon as it attaches to the base of the proximal phalanx
and the fibular sesamoid.
The fifth finger had a short proximal phalanx
with absent middle and distal phalanges.
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.
