A positive tangent sign predicts the repairability of rotator cuff tears.

Hypothesis: We hypothesize that patients with a positive tangent sign will have rotator cuff tears that are not able to be repaired primarily.

Methods: We performed a retrospective review of the charts of patients who had undergone surgery for repair of a rotator cuff tear. The operative note was reviewed to determine whether the cuff tear was primarily repaired.

Inpatient enoxaparin and outpatient aspirin chemoprophylaxis regimen after primary hip and knee arthroplasty: a preliminary study.

Our institution has used a thromboprophylaxis regimen consisting of inpatient enoxaparin and outpatient aspirin for patients at standard risk for venous thrombosis after hip and knee arthroplasty. We reviewed 500 cases using this protocol. Inpatient treatment with enoxaparin averaged 2.

Anterior cruciate ligament femoral tunnel drilling through anteromedial portal: axial plane drill angle affects tunnel length.

Purpose: The purpose of this study was to correlate femoral tunnel length with axial drilling angle through the anteromedial portal.

Methods: Ten anatomically correct Sawbones knee models (Pacific Research Laboratories, Vashon, WA) were used for this study. With the knee flexed to 120°, tunnels were drilled through a simulated anterior medial portal with a custom outrigger guide.

Mini-screw fixation for the treatment of proximal interphalangeal joint dorsal fracture-dislocations.

Purpose: Surgical intervention may be necessary to treat unstable dorsal fracture-dislocations of the proximal interphalangeal (PIP) joint of the hand. One method of stabilization is open reduction and internal fixation (ORIF). The purpose of this study was to assess the outcomes of ORIF for unstable dorsal fracture-dislocations of the PIP joint using mini-screws via a volar approach.
