BACKGROUND Rotator cuff tears are a common shoulder disorder resulting in significant disability to patients and financial burden on the health care system. While both surgical and nonsurgical management are accepted treatment options, there is a paucity of data to support a treatment algorithm for care providers. Defining variables to guide treatment(More)
BACKGROUND This study compared 2- and 3-dimensional (2D and 3D) radiographic measurements of anatomical and functional leg length and knee coronal and sagittal alignments and correlated these measurements with patients' leg-length perceptions. METHODS Patients without symptomatic spinal pathology, previous surgery of the spine, and lower extremities (140(More)
PURPOSE The primary purpose was to compare ipsilateral hip internal rotation (IR) in male and female athletes with or without an anterior cruciate ligament (ACL) tear. A secondary purpose was to compare radiographic markers of femoroacetabular impingement (FAI) in patients with or without an ACL tear. METHODS In this prospective case-control study, based(More)
STUDY DESIGN Systematic review of randomized controlled trials (RCTs). OBJECTIVES To determine the effectiveness of herbal medicine for nonspecific low back pain (LBP). SUMMARY OF BACKGROUND DATA Many people with chronic LBP use complementary and alternative medicine (CAM), visit CAM practitioners, or both. Several herbal medicines have been purported(More)
OBJECTIVES There is a recent trend toward increased surgical treatment of displaced midshaft clavicle fractures in adolescents. The primary purpose of this study was to evaluate the intrarater and interrater reliability of clavicle fracture classification systems and measurements of displacement, shortening, and angulation in adolescents. The secondary(More)
BACKGROUND Variations in scapular morphology have been associated with the development of atraumatic rotator cuff tears (RCTs). The critical shoulder angle (CSA) accounts for both glenoid inclination and lateral extension of the acromion. The impact of the CSA on outcomes after rotator cuff repair (RCR) has not been investigated previously. HYPOTHESIS Our(More)
STUDY DESIGN Prospective comparative study. OBJECTIVE To evaluate whether weight percentile (WP) increases after VEPTR insertion, and whether WP correlates with nutrition labs and pulmonary function. SUMMARY OF BACKGROUND DATA Children with thoracic insufficiency syndrome (TIS) often have "failure to thrive" (WP ≤5). Previous authors have reported an(More)
Coronal malalignment of the lower extremity is closely related to the onset and progression of osteoarthritis. Restoring satisfactory alignment after tibial osteotomy improves the long-term success of this conservative surgery. The purpose of our study was to determine (1) if there is a difference between two-dimensional (2D) and 3D measurements of the(More)
PURPOSE To qualitatively assess and to quantitatively analyze the long head of the biceps tendon (LHBT) in the region of the pectoralis major (PM). METHODS From 11 fresh cadaveric donors, 20 cadaveric shoulders without operative scars were dissected-mean age, 76.9 years (range, 61 to 93 years); male, 75%; left-sided, 55%; mean height, 67.8 inches (range,(More)
