Final answer:
A flexion deformity caused by a progressively contracting palmar fascia is known as Dupuytren contracture. This condition can cause fingers to bend towards the palm and is treated through various methods including surgery. The option (B) is correct.
Step-by-step explanation:
The term that refers to a flexion deformity caused by a slowly progressive contracture of the palmar fascia is Dupuytren contracture.
Dupuytren contracture is a condition where the fascia—the fibrous layer underneath the skin in the palm and fingers—becomes thickened and tight. This causes the fingers to be pulled towards the palm, which cannot be straightened completely, resulting in a characteristic flexed posture. Treatment often involves physical therapy, injections, or surgery to relieve the tension in the palmar fascia.
To understand the impact of this condition, it is important to recognize that the hands play a critical role in daily activities and repetitive strain or injury can lead to disorders affecting their function. An example of a disorder likely to be caused by repetitive strain, such as the use of a jackhammer, is Carpal tunnel syndrome. Therefore, option (B) is correct.
