Randomized Controlled Trial Clinical Trial
Mini-open blind procedure versus limited open technique for carpal tunnel release: a 30-month follow-up study.
To evaluate prospectively the safety and effectiveness of a mini-open blind technique for carpal tunnel release (group A) when compared with a limited open technique (group B). ⋯ The blind mini-invasive technique has been shown to be as safe as traditional techniques but the recovery period is significantly shortened. With the technique we described a low recurrence rate was observed. All patients in group A reported great reduction in preoperative pain and numbness.

Randomized Controlled Trial Comparative Study Clinical Trial
Excision of the trapezium for osteoarthritis of the trapeziometacarpal joint: a study of the benefit of ligament reconstruction or tendon interposition.
To investigate whether palmaris longus interposition or flexor carpi radialis ligament reconstruction and tendon interposition improved the outcome of excision of the trapezium for the treatment of painful osteoarthritis of the trapeziometacarpal joint. ⋯ The outcomes of these 3 variations of trapeziectomy were very similar at 1-year follow-up evaluation. In the short term at least there appears to be no benefit to tendon interposition or ligament reconstruction.

Randomized Controlled Trial Clinical Trial
Modified transthecal digital block versus traditional digital block for anesthesia of the finger.
This study compared the modified transthecal digital block (MTDB) technique with the traditional digital block (TDB) according to the degree of discomfort caused by injection and to the onset and the duration of anesthesia. ⋯ The effect of MTDB is equal to that of TDB in terms of pain perception. For the dorsal and radial proximal zones, the TDB appears to have better distribution of anesthesia. The MTDB has slower onset to anesthesia than the TDB.

Randomized Controlled Trial Comparative Study Clinical Trial
External fixation of the distal radius: to predrill or not to predrill.
Using both clinical and laboratory studies we investigated whether predrilling before insertion of external fixation pins is necessary for use in treating distal radius fractures. Our clinical study included 50 consecutive external fixators (4.0- and 2.5-mm pins) using 100 predrilled and 100 direct-drilled pins placed in a randomized manner. ⋯ There were, however, significantly elevated temperatures with the direct-drilled technique. We therefore recommend predrilling even though the temperature differences in this bone with this fixator were not clinically evident.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of transthecal and subcutaneous single-injection digital block techniques in cadaver hands.
A controlled, randomized single-blinded study was performed on the thumbs and little fingers of 20 cadaver hands. The digits were randomly divided into 2 groups. In the transthecal group, 2 mL of 0.5% methylene blue was injected into the tendon sheath at the A1 pulley. ⋯ In the transthecal group, intra-articular staining of the metacarpophalangeal joint was noted in 3 little fingers and 1 thumb. This complication did not occur in the subcutaneous group. This difference was significant (p < .05).
