Background: Modified Phemister operation has been widely used for the treatment of acute acromioclavicular (AC) joint dislocation. Additionally, the use of suture anchor for coracoclavicular (CC) fixation has been reported to provide CC stability. This study was conducted to evaluate the clinical and radiological results of a modified Phemister operation with CC ligament augmentation using suture anchor for acute AC joint dislocation.Methods: Seventy-four patients underwent the modified Phemister operation with CC ligament augmentation using suture anchor for acute AC joint dislocation and were followed-up for an average of 12.3 months. The visual analogue scale (VAS), range of motion, Constant score, and Korean shoulder scoring system (KSS) were used for clinical assessment. Acromioclavicular interval (ACI), coracoclavicular distance (CCD), and acromioclavicular distance (ACD) were obtained to evaluate the radiological assessments.Results: At the last follow-up, the mean VAS Score was 1.7 points, the mean joint range of the forward flexion was 164.6°, external rotation at the side was 61.2°, and internal rotation to the posterior was a level of T12. The mean Constant score and the mean KSS was 82.7 points and 84.2 points, respectively. At the mean ACI, CCD, and ACD, significant differences were found preoperatively and at the last follow-up. When the ACI, CCD, and ACD were compared with the contralateral unaffected shoulder at the last follow-up, the affected shoulders had significantly higher values.Conclusions: The modified Phemister operation with CC ligament augmentation using suture anchor is clinically and radiologically effective at acute AC joint dislocation.
Purpose: This study was performed to evaluate the results of treating intertrochanteric fracture with proximal femoral nail antirotation (PFNA). Materials and Methods: We performed PFNA on 41 intertrochanteric femur fracture patients from May 2008, to August 2010. We analyzed the operation time, blood loss, recovery of ambulatory function, T-score, the tip apex distance (TAD), the sliding distance of the blade, neck-shaft angle, and complications. Results: The mean operation time was 51 minutes and the mean amount of blood loss was 350 ml. The time to ambulation averaged 7.2 days. Thirty-two cases (79%) recovered their previous walking status at 6 months after operation. The average T-score was 3.3 and TAD was 12.3 mm (8.6∼27 mm). 35 cases (87%) achieved acceptable reduction. The average amount of PFNA blade sliding was 3.3 mm. The neck-shaft angle was changed 2.6 degrees varus displacement at the final follow-up. There was one case of nonunion due to tuberculosis infection. Conclusion: The findings from this study indicate that PFNA is a useful and reliable choice for the treatment of intertrochanteric fracture of the femur.
Purpose: There are numerous opinions about the methods and usefulness of minimizing leg length discrepancies after hip arthroplasty. In this study, we tried to evaluate the usefulness of an intraoperative x-ray in addition to preoperative templating for minimizing leg length discrepancy.
Materials and Methods:We reviewed pre-and post-operative pelvis AP x-rays of 46 patients who underwent hip arthroplasty due to a traumatic femoral neck fracture or intertrochanteric fracture between May 2008 and February 2009. A leg length discrepancy is the difference in vertical distance between a horizontal line drawn along the bottom of the ischial tuberosities and the most inferior points of the lesser trochanter. It was measured in a pelvis AP x-ray.In each case, pre-operative templating was performed and an intraoperative pelvis AP x-ray was taken again to assess the accuracy of preoperative planning. Implant positions were readjusted when necessary.
Results:The mean post-operative leg-length discrepancy was 0.3 mm (SD, 3.1 mm). The range was from -5.8 mm to +5.9 mm.
Conclusion:Combining preoperative templating and intraoperative x-rays is a useful method of minimizing leg length discrepancy during hip arthroplasty.
