One-stage total hip arthroplasty for advanced hip tuberculosis combined with developmental dysplasia of the hip: A case report.

BACKGROUND

A patient with advanced tuberculosis of the hip joint combined with Crowe type IV developmental dysplasia of the hip (DDH) and a drainage sinus is a rare condition. There are no previous reports of this condition, and it is a complex challenge for surgeons to develop a treatment scheme.

CASE SUMMARY

We report a 73-year-old male patient with severe hip pain and drainage sinus of the left hip for one month. Approximately 40 years ago, a drainage sinus occurred at the lateral left hip was healed at the local hospital with anti-infectious therapy. After the sinus healed, gradual pain occurred in the left hip for 40 years. Approximately one month prior, hip pain was sharply aggravated, and a drainage sinus reoccurred in the left hip. The X-ray and computed tomography examinations showed destruction of the head and neck of the left femur, as well as an acetabular deformity. The results of antibody and Xpert were positive. Therefore, the patient was diagnosed with advanced TH combined with Crowe type IV DDH. After 22 d of treatment with anti-tuberculosis chemotherapy, the sinus healed, and the patient underwent one-stage total hip arthroplasty (THA) surgery consisting of debridement, osteotomy, and joint replacement. After surgery, the patient received anti-tuberculosis chemotherapy drugs for nine months, with no recurrent infection. After one year of follow-up, the Harris score of the patient increased from 21 pre-THA to 86.

CONCLUSION

Although drainage sinuses are a contraindication to one-stage THA, one-stage THA is still an effective and safe surgical method after the sinus heals.
