Outcomes of Cutaneous Scar Revision During Surgical Implant Removal in Children with Cerebral Palsy.

Background: Children who have had surgery involving the placement of an implant frequently undergo a subsequent surgery for hardware removal. The cosmesis of surgical scars following initial and subsequent surgeries is unpredictable. Scar incision (subsequent surgical incision through the initial scar) or excision (around the initial scar) is selected on the basis of the quality of the initial scar.

Ultrasound for Infants at Risk for Developmental Dysplasia of the Hip.

The best screening method for developmental dysplasia of the hip is controversial. Ultrasonography is sensitive, but cost-effectiveness may limit its use. This study assessed whether ultrasound screening would increase in effectiveness if targeted toward infants with established risk factors for developmental dysplasia of the hip and normal findings on physical examination.

Gravity versus manual external rotation stress view in evaluating ankle stability: a prospective study.

Background: The purpose of this prospective study was to determine whether gravity versus manual external rotation stress testing effectively detects widening of the medial clear space in isolated ankle fractures when compared with the uninjured contralateral side.

Methods: Manual external rotation stress and gravity stress tests were performed on injured and uninjured ankles of ankle fracture patients in a clinic setting. Medial clear space measurements were recorded and differences between gravity and manual stress views were determined.

Effect of graft shape in lateral column lengthening on tarsal bone position and subtalar and talonavicular contact pressure in a cadaveric flatfoot model.

Background: Lateral column lengthening (LCL) has been used for correction of flatfoot deformity. The purpose of this study was to determine the effect of LCL graft shape on tarsal bone position and talonavicular and subtalar joint pressure.

Methods: A flatfoot model was created in 6 cadaveric specimens.

Effects of flexor-pronator muscle loading on valgus stability of the elbow with an intact, stretched, and resected medial ulnar collateral ligament.

Background: The medial ulnar collateral ligament (MUCL) is an important passive stabilizer to the valgus stresses that athletes experience during overhead throwing motion. However, the role of the flexor-pronator muscles as active stabilizers to valgus stress is not well defined in the literature. The objectives of this study were to quantify the relative contribution of the individual flexor-pronator muscles to valgus stability of the elbow and how this relationship was affected by ligament status.

The effect of glenohumeral position on the shoulder after traumatic anterior dislocation.

Background: Previous cadaveric studies suggest that positioning the shoulder in an externally rotated position reduces displaced Bankart lesions through a coaptation effect.

Hypothesis: We hypothesized that positioning the glenohumeral joint in an externally rotated position creates contact pressure between the subscapularis and the anterior labrum.

Study Design: Descriptive laboratory study.
