AB  - OBJECTIVE: The hip joint can be affected by extraspinal diffuse idiopathic 
      skeletal hyperostosis (DISH). This study aimed to compare the clinical 
      characteristics of hips with DISH to those with mixed-type femoroacetabular 
      impingement symptoms (FAIS). In addition, patient-reported outcome (PRO) scores 
      were reported among patients with DISH involving the hip joint who underwent 
      arthroscopic treatment. METHODS: A retrospective analysis was performed using 
      data from patients who underwent hip arthroscopy between 2017 and 2021. Patients 
      who had a preoperative diagnosis of extraspinal DISH of the hip joint and 
      postoperative Hip Outcome Score-Activities of Daily Living (HOS-ADL), Hip Outcome 
      Score-Sports Subscale (HOS-SSS), International Hip Outcome Tool 12-component form 
      (iHOT-12), modified Harris Hip Score (mHHS) and visual analog scale (VAS) for 
      pain scores were enrolled in the study. The patients' characteristics were 
      compared with those of a control group (1:2) consisting of mixed-type patients 
      with FAIS. The control group was matched in terms of age, sex, body mass index 
      (BMI), and symptom duration. RESULTS: Eleven hips (0.87%) with extraspinal DISH 
      (study group) were matched to 22 FAIS hips (control group). All the patients were 
      male. The mean age of patients was 42.0 +/- 8.0 in the study group. The study group 
      was characterized by a larger preoperative alpha angle (79.1 +/- 6.8 vs 64.8 +/- 9.7, 
      P < .001), lateral center-edge angle (LCEA) (49.7 +/- 6.0 vs 40.7 +/- 3.2, P < .001), 
      and postoperative LCEA (36.6 +/- 3.0 vs 34.2 +/- 2.0, P = .013). In addition, a 
      higher proportion of acetabular (81.8% vs 31.8%, P = .007) and femoral head 
      chondral lesions (45.5% vs 9.1%, P = .016). Cartilage damage has the potential to 
      affect the prognosis of arthroscopic treatment. Nevertheless, at the final 
      follow-up, patients with DISH experienced a significant increase in range of 
      motion (ROM), notable enhancements in all PROs, and favorable rates of minimal 
      clinically important difference (MCID) for the PROs. CONCLUSION: The occurrence 
      of DISH in the hip joint is considerably infrequent, characterized by hip pain 
      and limited ROM. Despite increased alpha angle and LCEA, and more acetabular and 
      femoral head chondral damage noted at the time hip arthroscopy, patients with 
      DISH observed a significant improvement in ROM, notable enhancements in all PROs, 
      and favorable rates of MCID for the PROs.
