Abstract: (2025 Views)
Introduction: The psoas muscle plays an essential role in the hip and lumbar spine. Total hip arthroplasty surgery can lead to alterations in the ipsilateral psoas muscle that may affect lumbar biomechanics and accelerate disc degeneration. We introduce a clinical study that suggests the theory of a potential association between unilateral psoas muscle atrophy after hip replacement surgery and subsequent low back pain.
Case description: A 53-year-old man with a history of right total hip arthroplasty for osteoarthritis presented with left lumbosciatalgia six years after surgery. In the physical examination, the patient exhibited weakness 2/5 in Kendall´s muscle grading system in the right hip flexion and left extensor hallucis longus and triceps surae. Magnetic resonance imaging revealed a degenerative disk L5-S1 and severe unilateral atrophy of the right psoas muscle. Conservative treatment through physiotherapy was initiated, but persistent pain ultimately necessitated microdiscectomy at the L5–S1 level.
Conclusion: Total hip arthroplasty surgery may lead to long-term unilateral atrophy of the ipsilateral psoas muscle and alter lumbar biomechanics, potentially accelerating the disc degeneration process and subsequent low back pain. Investigating this possible correlation may offer greater clarity regarding low back pain after total hip arthroplasty. In our case, conservative treatment through 15 sessions of physical therapy produced very limited improvement, and advanced discopathy required surgical intervention to decompress the affected lumbar root.
