Comparative Study
Analysis of a knotless flexor tendon repair using a multifilament stainless steel cable-crimp system.
To compare the biomechanical and technical properties of flexor tendon repairs using a 4-strand cruciate FiberWire (FW) repair and a 2-strand multifilament stainless steel (MFSS) single cross-lock cable-crimp system. ⋯ A cable crimp flexor tendon repair may offer an attractive alternative to current repair methods. The benefits may be important especially for flexor tendon repair in zone 2 or for the repair of multiple tendons.

Comparative Study
Effect of partial, distal epicondylectomy on reduction of ulnar nerve strain: a cadaver study.
To compare the decrease in ulnar nerve strains using a modification of medial epicondylectomy by removing the distal half of the medial epicondyle with in situ decompression and partial medial epicondylectomy. ⋯ The results of the present cadaveric study suggest that excision of the distal half of the medial epicondyle in cubital tunnel syndrome may decrease ulnar nerve strain effectively. The clinical effect of decrease in nerve strain and the indications for the procedure need to be investigated.

Multicenter Study Comparative Study
The minimal clinically important difference after simple decompression for ulnar neuropathy at the elbow.
Establishing minimally clinically important difference (MCID) for patient-reported outcomes questionnaires is an important component of outcomes research to understand treatment effectiveness from the patient's perspective. For patients with ulnar neuropathy at the elbow (UNE), these assessments are vital to examine how much change in the questionnaire scores equate to patient satisfaction. ⋯ Therapeutic II.

Radioscapholunate arthrodesis with excision of the distal scaphoid: comparison of contact characteristics to the intact wrist.
To evaluate the midcarpal contact characteristics at the lunocapitate (LC) and scaphotrapezio-trapezoidal (STT) joints in 3 wrist conditions: intact, after simulating a radioscapholunate (RSL) arthrodesis, and after an RSL arthrodesis with distal scaphoid excision (DSE). ⋯ Radioscapholunate arthrodesis results in increased midcarpal contact pressures that may explain the clinical incidence of midcarpal arthritis. Excision of the distal scaphoid further increases contact pressures in the remaining midcarpal joint and may further increase the incidence of midcarpal arthritis. These alterations in contact characteristics of the midcarpal joint should be considered when excising the distal scaphoid for improved range of motion.
