A row pattern has a predominantly distal distribution, involving the IP joints more than the MCP joints, which creates a diagnostic challenge with OA.
The MCP joint collateral ligaments of the thumb and lesser digits extend with slight obliquity from shallow depressions on the radial and ulnar aspects of the metacarpal heads to the bases of the proximal phalanges.
In EF4T and EMT, (9,15) ECRL and ECRB is used as the donor tendon, respectively with TFL as a tendon graft to restore the active flexion of the MCP joints and extension of the interphalangeal joints of the digits.
This stabilises the IP joint in extension and causes semi active flexion at the MCP joint and allows pulp-to-pulp pinch.
Regarding the orthotic management of the nonfunctional hand, Perry stated that power loss results from the wrist traveling an oblique path while the WDFHO must be aligned longitudinally to match the anatomical axes of the wrist and MCP joints
Figure 4 shows the angular displacement of the PIP and MCP joints
for the control group and experimental group.

Whether these signs or other secondary impairments develop, such as MCP instability and/or carpo-metacarpal (CMC) (sub) luxation, depends on such factors as hand dominance and use, duration of the palsy, configuration of MCP joint
surfaces and joint laxity.
The glove uses stretching fabric for the back side of the MCP joints
and semistretching fabric for the palm side so that stretching along the finger direction is avoided.
Swelling, warmth, limitation of movement, and tenderness were noted at the ankle, wrist, PIP and MCP joints
The novel 4-DOF planar robot consists of four revolute joints, each one representing the proximal interphalangeal (PIP) and MCP joints
of the thumb and index finger (Figure 2).
Ulnocarpal joint erosions, midcarpal, and MCP joint
erosions were the most frequent (Table 2).
