Retention of the well-fixed implant in the single-stage exchange for chronic infected total hip arthroplasty: an average of five years of follow-up.

Purpose: Removal of an infected prosthesis was considered the gold standard for eradication of infection. However, removal of well-fixed components can result in structural bone damage and compromised reconstruction. In these situations we questioned whether the infection after the total hip arthroplasty could be treated effectively and retain the well-fixed implant in a single-stage exchange.

[The method and result analyses of pathogenic bacteria culture on chronic periprosthetic joint infection after total knee arthroplasty and total hip arthroplasty].

Objective: To analyze the results of pathogenic bacteria culture on chronic periprosthetic joint infection after total knee arthroplasty (TKA) and total hip arthroplasty (THA).

Methods: The medical data of 23 patients with chronic periprosthetic joint infection after TKA or THA from September 2010 to March 2014 were reviewed. Fifteen cases of TKA and 8 cases of THA were included in this study.

Treatment of the femoral shaft nonunion with double plate fixation and bone grafting: A case series of 14 patients.

Introduction: The management of femoral shaft nonunion still remains a challenge in orthopaedic surgery. It represents a serious postoperative problem for the patient, associated with plate breakage and loosening, bone defect, shortening deformity and infection. A double plate fixation combined with bone grafting may become a promising therapeutic strategy for the treatment of patients with femoral shaft nonunion.

[Total hip arthroplasty for non-functional bony ankylosed hip in young and middle-aged patients].

Objective: To explore the effectiveness of total hip arthroplasty (THA) for non-functional bony ankylosed hip in young and middle-aged patients.

Methods: Between January 2010 and March 2013, 14 cases (19 hips) of non-functional bony ankylosed hip were treated by THA. There were 9 males and 5 females, aged 37.

[Effect of femoral offset change on pain and function after total hip arthroplasty].

Objective: To investigate the effects of altering the femoral offset after total hip arthroplasty on postoperative pain and function.

Methods: A total of 162 patients undergoing single total hip arthroplasty between March 2009 and December 2011 met the inclusion criteria. According to difference of femoral offset between operative side and contralateral side, the patients were divided into 3 groups: decreased offset group (< 5 mm, 30 cases), normal offset group (-5-5 mm, 87 cases), and increased offset group (> 5 mm, 45 cases).
