Objective: To observe the early wound healing of orthopedic surgery in human immunodeficiency virus (HIV) carrier patients treated with optimized auxiliary treatments.
Methods: During a period of 48 months, according to the inclusion and exclusion criteria plus CD4⁺ T lymphocyte count, the patients scheduled for orthopedic surgery (including HIV positive and negative) were divided into group A (HIV positive, CD4<500/ml) with optimized auxiliary treatments, group B (HIV positive, CD4 ≥ 500/ml) and group C (HIV negative) on prophylactic antibiotic therapy alone. Wound healing of 3 groups were observed postoperatively. The rates of clinical wound infection were compared among 3 groups.
Results: A total of 471 cases (n = 79, HIV+; n = 392, HIV-) were selected due to fresh fracture (n = 544, 77.28%), fracture of spine (n = 57, 12.31%), mal-union (n = 13, 2.76%), aseptic necrosis (n = 15, 3.18%) and osteoarthritis (n = 21, 4.46%). During surgery, early open reduction and plate screw internal fixation (group A, n = 23; group B, n = 21; group C, n = 274); pedicle screw internal fixation (group A, n = 5; group B, n = 6; group C, n = 47); total joint replacement (group A, n = 3; group B, n = 4; group C, n = 8); interlocking intramedullary nail fixation (group A, n = 7; group B, n = 4; group C, n = 35) and other operations (group A, n = 3; group B, n = 3; group C, n = 28). For infections, 2 cases (4.88%) were observed in group A, 3 (5.26%) in group B and 26 (6.63%) in group C. The differences were statistically insignificant.
Conclusion: Reasonable perioperative adjuvant treatments, including use of antibiotic, nutritional supports, immunomodulators and anti-retroviral drugs, are offered to HIV infected patients undergoing orthopedic surgery. Their risks of postoperative wound infection may be controlled.
