Screw inserting in different phase of cement affect the pull-out strength of cement augmented screws.

Background: For large bone defects, after curettage of aggressive bone tumors; such as giant-cell tumors, cementation with supplement internal fixation was used to prevent subsequent collapse of the cement-bone constructs. The purpose of this study is to compare the pull-out strength of cement augmented screws between inserting screws in the working phase or hard phase of bone cement.

Hypothesis: Timing at which completed screw insertion takes place affecting the pull-out strength of cement augmented screws.

Comparing the running subcuticular technique versus the Donati technique in open carpal tunnel release: a randomized controlled trial.

Background: There are various skin suture techniques for wound closure following carpal tunnel release, and well-performed suturing will result in low post-operative scar tenderness. The aim of this study was to compare the Donati suture technique and running subcuticular technique in terms of surgical scar, post-operative pain and functional outcome in open carpal tunnel release.

Methods: One-hundred forty-two patients were randomized using a computer-generated random number table into two groups receiving either running subcuticular suturing or Donati suturing after surgical intervention.

Location of the radial nerve along the humeral shaft between the prone and lateral decubitus positions at different elbow positions.

Identification of the radial nerve is important during the posterior approach to a humerus fracture. During this procedure, the patient can be placed in the prone or lateral decubitus position depending on the surgeon's preference. The distance from the radial nerve to the osseous structures will be different in each position.
