Randomized Controlled Trial Comparative Study
Work of flexion related to different suture materials after flexor digitorum profundus and flexor digitorum superficialis tendon repair in zone II: a biomechanical study.
Repair of both flexor digitorum profundus (FDP) and flexor digitorum superficialis (FDS) tendons is commonly performed in zone II flexor tendon injuries; however, the bulk of the repair may impair tendon gliding. We evaluated whether repairing 1 slip of FDS tendon and resecting the other would significantly decrease work of flexion and whether suture material affected this interaction in an in vitro study. ⋯ Resection of 1 slip of FDS tendon significantly reduces work of flexion in zone II flexor tendon repair. Suture material had no effect on this interaction.

Randomized Controlled Trial
Dose effectiveness of transthecal digital block.
The optimal volume of local anesthetic for transthecal digital block has not yet been identified. The goal of this study was to understand the effect of different volumes of local anesthetic using a modified transthecal digital block. ⋯ The effectiveness of the 3-mL modified transthecal digital block is greater than the 1- and 2-mL blocks in terms of rapidity of onset, completeness, and duration of anesthesia.

Randomized Controlled Trial
Open compared with 2-portal endoscopic carpal tunnel release: a 5-year follow-up of a randomized controlled trial.
The purpose of this investigation was to extend the previously reported short-term randomized trial of open and endoscopic carpal tunnel release in patients with carpal tunnel syndrome (CTS) to compare outcomes 5 years after surgery. ⋯ Therapeutic I.

Randomized Controlled Trial Comparative Study
Comparison of 2 methods of immobilization of fifth metacarpal neck fractures: a prospective randomized study.
The objective of this study was to prospectively compare the effectiveness of 2 methods of cast immobilization for fifth metacarpal neck fractures with respect to the time required for cast application, durability and tolerability of the cast, efficacy of maintaining reduction, and postimmobilization range of motion. ⋯ There was no difference between the 2 groups on maintaining the reduction on final lateral radiographs. Stiffness was not a complication of either group. Advantages of the MCP-ext cast include quicker application and, to a much lesser degree, better tolerability, range of motion, and final grip strength.

Randomized Controlled Trial
Injection of dexamethasone versus placebo for lateral elbow pain: a prospective, double-blind, randomized clinical trial.
We tested the hypothesis that there is no difference in disability, pain, and grip strength 1 and 6 months after corticosteroid and lidocaine injection compared with lidocaine injection alone (placebo). ⋯ Therapeutic I.
