Secondary Condition Claim · VASRD 5252
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Limitation of Flexion of the Thigh (Hip) when it develops after Sacroiliac Injury and Weakness.
Primary condition · VASRD 5236
Sacroiliac Injury and Weakness
The sacroiliac joints connect the base of the spine to the pelvis, and injury or weakness there can cause chronic lower back and hip pain, especially with lifting, twisting, or prolonged standing. It's commonly linked to lifting injuries or repetitive strain from carrying gear during service.
Secondary condition · VASRD 5252
Limitation of Flexion of the Thigh (Hip)
Hip flexion limitation makes it difficult to walk, sit, squat, or bend at the waist.
The VA rates Limitation of Flexion of the Thigh (Hip) the same way whether it's claimed directly or as secondary to Sacroiliac Injury and Weakness — severity of Limitation of Flexion of the Thigh (Hip) itself determines the percentage.
Example combined rating
20% Sacroiliac Injury and Weakness + 10% Limitation of Flexion of the Thigh (Hip) = 28%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 20% and 10% combine to 28%, not 30%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
