STUDY DESIGN Cross-sectional. OBJECTIVES The purpose of this study is to describe the normative data of the sagittal plane on pediatric age population, and to document the evolution of sagittal alignment with growth. SUMMARY OF BACKGROUND DATA Having normative data about the sagittal plane is an integral part in the planning of the three-dimensional(More)
Alignment radiographs of 174 extremities in patients undergoing total knee arthroplasty were measured to determine the variability in valgus cut angle (VCA) and the anatomical factors that affect the VCA necessary to restore the mechanical axis. The VCA averaged 5.6 degrees +/- 1.0 degrees with a range of 2 degrees to 9 degrees . With the 3 different(More)
STUDY DESIGN Outcome study to determine the internal consistency, and validity of adapted Turkish version of Scoliosis Research Society-22 (SRS-22) Instrument. OBJECTIVES To evaluate the validity and reliability of adapted Turkish Version of SRS-22 questionnaire. SUMMARY OF BACKGROUND DATA The SRS-22 questionnaire is a widely accepted questionnaire to(More)
STUDY DESIGN Experimental study. OBJECTIVES To investigate the effects of pedicle screw insertion on spinal canal and pedicle morphology in immature pigs, and, if transpedicular fixation has an effect, to document whether this occurs because of the inhabitance of the screw inside the growth plate (neurocentral cartilage [NCC]) or because of compression(More)
INTRODUCTION This study was conducted to determine the survival of different glenoid component designs, assess the reasons for revision surgery, and identify patient and diagnostic factors that influence this need. METHODS Between January 1, 1984, and December 31, 2004, 1337 patients underwent 1542 total shoulder arthroplasties with 6 types of glenoid(More)
The authors studied 32 patients to delineate the reliability of well-defined but frequently extended indications to define the ideal patient who will benefit from convex growth arrest. Mean age at the time of convex growth arrest was 29 (range 6-72) months, and average follow-up was 40 (24-120) months. Mean Cobb angle was 55 degrees (31-105 degrees) before(More)
BACKGROUND Total shoulder arthroplasty is traditionally performed through an anterior deltopectoral exposure with subscapularis tenotomy. Postoperative subscapularis dysfunction is common and adversely affects clinical outcomes. Consequently, surgeon interest in lesser tuberosity osteotomy has grown in an effort to improve subscapularis repair strength.(More)
BACKGROUND Reported healing rates of a subscapularis tenotomy have been extremely variable in the literature. The purpose of this study was to document the subscapularis healing rate after subscapularis tenotomy using ultrasound, and to correlate healing with physical examination findings and shoulder internal rotation strength. METHODS Fifteen patients(More)
BACKGROUND Nonunion is a challenging and not uncommon complication of distal humeral fractures. Our long-term experience with linked semiconstrained total elbow arthroplasty as a salvage procedure for patients with distal humeral nonunion not amenable to internal fixation was investigated. METHODS Ninety-one consecutive patients (ninety-two elbows)(More)
PURPOSE The purposes of this study was to better understand the utilization of anterior acromioplasty over time, in the absence of rotator cuff repair; to examine the relation to patient characteristics (age, sex) and types of rotator cuff pathology (inflammation or fibrosis, partial-thickness tearing, full-thickness tearing undergoing debridement); and to(More)
