Article entitled "short-term effectiveness analysis of one-stage bilateral total hip arthroplasty by direct anterior approach" written by gong dawei, yang yunkang, chen ge, and yin yiran was reviewed.Publication date is unknown.The aim of our study was to compare the effectiveness of one-stage bilateral total hip arthroplasty by direct anterior approach (daa) and by posterolateral approach, and to investigate the application value of daa in one-stage bilateral total hip arthroplasty.From june 2010 to november 2015 - 34 patients underwent simultaneous bilateral hip replacement using daa (group a) and 31 patients who underwent simultaneous bilateral hip replacement using as posterolateral approach (group b).All patients were implanted with either a corail or trilock stem, pinnacle cup (with screws), and ceramic on ceramic or ceramic on poly bearing.Adverse events: group a ¿ 4 hips developed lateral thigh skin numbness due to lateral femoral cutaneous nerve injury, which resolved spontaneously after 3 months without special treatment.Group b ¿ 1 hip developed sciatic nerve contusion, which recovered after nutritional nerve treatment.Group a ¿ 1 hip had intraoperative greater trochanter fracture and was treated with double-strand wire cerclage, which healed 3 months after surgery.Group b ¿ 2 hips had intraoperative femoral fracture and healed after wire banding and 2 hips had hip dislocation due to intraoperative change of body position and were successfully treated with manual reduction under anesthesia.Group a -2 hips had surgical incision exudation and healed after primary joint cavity debridement and drainage (without prosthesis removal) at 7 days after surgery.Group b ¿ 2 hips had posterior venous thrombosis due to bed rest time and recovered after regular anticoagulant therapy.Group b ¿ 3 patients had postoperative difference in the length of lower limbs of more than 1 cm, of which 2 cases were not recovered to the anatomical length, and 1 case was not recovered to the anatomical length unilaterally, with a total of 5 hips abnormal.
