I reviewed P today and explained to him that he used his “get out of jail card” with the successful interspinous focal steroid injection between L4 and L5 has treated the periostitis and ligament injury. Within days he had an improvement in the local pain and the impulse pain and was moving freely. He lost his impulse pain and began to move freely. Examination I saw him jog across the road today as he was running late, so I think he is moving freely. His general movements are fine without any obvious issues. He was able to bend forward and effortlessly reach just to his ankles; extension was normal. His straight leg raise was increased on the right to approximately 80 degrees limited by hamstring tightness, and on the left to 70 degrees limited by hamstring tightness. There was no tenderness to palpation in his buttocks or spinous and interspinous processes today.
