The purpose of this study was to determine if three-dimensional computed tomography (3-D CT) scans of the glenoid can be used to accurately quantify, by means of a glenoid index, bone loss in patients with anterior glenohumeral instability, and to compare the results with arthroscopic measurements to determine if the 3-D CT scan can preoperatively predict which patients with anterior glenohumeral instability will benefit from a bone grafting procedure. ⋯ Level III, development of diagnostic criteria with universally applied reference (nonconsecutive patients).

Randomized Controlled Trial Comparative Study
Assessment of pain relief provided by interscalene regional block and infusion pump after arthroscopic shoulder surgery.
This study was performed to evaluate the efficacy of interscalene regional blocks and infusion pumps for postoperative pain control after arthroscopic subacromial decompression with or without arthroscopic rotator cuff repair. ⋯ Level II, prospective comparative therapeutic study.

Comparative Study
Arthroscopic perspective of the axillary nerve in relation to the glenoid and arm position: a cadaveric study.
The purposes of this study were to examine the morphologic features of the axillary nerve and its relation to the glenoid under an arthroscopic setup, and to determine the changes in nerve position according to different arm positions. ⋯ Knowledge of the anatomy of the axillary nerve aids the shoulder surgeon in avoiding nerve injury during arthroscopic procedures. Abduction-neutral rotation may be more helpful for arthroscopic surgeons performing procedures in the anteroinferior glenoid with the nerve being farther away from the working field.

A case is described in which hot irrigation fluid used during a routine knee arthroscopy caused severe morbidity. The patient sustained full-thickness skin burns requiring debridement, a muscle flap, and split-skin grafting. ⋯ The underlying factors included equipment failure but also a delay in appreciating the severity of the soft-tissue damage. This case highlights the need for a robust protocol for the management of warming the irrigation fluid, as well as monitoring the actual fluid temperature.
