The Metacarpophalangeal (MCP) joint of the thumb are stabilize by two major ligaments. Mechanism of Injury / Pathological Process

The ligamentous anatomy is analogous to that seen in the finger MCP joints, with extrinsic tendons providing additional support

Abductor pollicis brevis (APB) muscles insert partially on the sesamoids and provide stability against hyperextension forces.

The articular morphology found in this joint makes it the most varied motion of all joints, with range of motion of 6 to 86 degree in flexion-extension. The thumb MCP is similar in anatomical appearance to those of the finger,but essentially functions as a hinge or ginglymus joints. Thumb ligament injuries are common, particularly those involving the metacarpophalangeal joint.Two major ligaments stabilize the MCP joint of the thumb: the ulnar collateral ligament (UCL) and the radial collateral ligament (RCL) Clinical Relevant Anatomy

3 Mechanism of Injury / Pathological Process.

Conclusion: Soft neoprene thumb abduction splints have a positive effect on weight bearing and upper limb function in children with thumb-in-palm deformity, particularly with the splint on.

The caregivers/parents perceived the home programme as easy to follow, and those who were prescribed the splint mostly reported that it was easy to use. Protective extension decreased within both groups except for the intervention group with the splint on. Only dissociated movement showed a clinically relevant medium effect size for change within the control group. The effect size for improvement within the intervention group was large for dissociated movement and weight bearing with and without the splint on as well as for grasps with the splint on. Clinically relevant between group differences indicated by effect sizes were found however with large effect sizes for the total QUEST score and weight bearing. Results: No statistically significant differences between the intervention and control groups were found. The intervention group additionally received a soft neoprene thumb abduction splint. Both the intervention and control groups received monthly individual occupational therapy and a home programme over a three month period. The Quality of Upper Extremity Skills Test (QUEST) was used to assess upper limb function in terms of dissociated movement, grasps, weight bearing and protective extension to obtain baseline information. Twenty-eight CP children between the age of 18 and 68 months, presenting with thumb-in-palm deformity, functioning on a Level II to IV on the Gross Motor Function Classification Scale (GMFCS) participated in the study. Methods: A non-blinded randomised intervention study was carried out in a CP clinic at a tertiary level public hospital. There is insufficient evidence for the effectiveness of this splint on upper limb function in children with CP with a thumb-in-palm deformity within the South African public health context.

The soft neoprene thumb abductor splint is prescribed by occupational therapists to correct these impairments. Introduction: Children with cerebral palsy (CP) have limitations in hand function due to weakness and spasticity, with long term effects causing shortening and stiffness of muscles in the hand and arm.
