Gluteus Maximus Distal Myotendinous Junction Tear in a Pickleball Player: A Case Report

Abstract

Abstract A 72-year-old male presented for evaluation of a 2-wk history left buttock pain that began while playing pickleball. He sustained a left inversion ankle sprain while in a squatted position and landed on his left buttock. Four days after his injury, he developed extensive bruising involving his lower back, buttock, and left thigh. On examination, he had tenderness to palpation at the left side of the sacrum and in the region of the deep external rotators. Left hip range of motion was full in extension but limited to 90° of flexion, which reproduced left-sided buttock pain. External rotation provoked pain, but internal rotation was full and pain free. MRI of the pelvis demonstrated a grade 2 partial thickness tear of the left gluteus maximus muscle at its distal myotendinous junction with associated retraction and intramuscular hematoma. He was managed with compression with biking shorts, icing, acetaminophen, and physical therapy. He returned to pickleball approximately 4 wk after his injury, and at his 4-wk follow-up, he reported 99% improvement in his symptoms with the only remaining complaint being minimal discomfort with gluteal stretching.
