One hundred twenty-seven shoulders treated with replacement arthroplasty for osteonecrosis of the humeral head were reviewed and assessed by mailed questionnaire for results, durability, and complications. These included 71 humeral head replacements and 56 total shoulder replacements. Thirty-six shoulders were lost to follow-up because of death of the patient; an additional 3 shoulders were locking survey follow-up. ⋯ The most common postoperative complication was rotator cuff tearing, found in 23 (18.1%) of 127 shoulders. This complication was more common in shoulders with a history of any surgery. The cause of osteonecrosis and previous treatment have important implications for the results of shoulder replacement for this disease.

Case ReportsIatrogenic ulnar nerve injury after percutaneous cross-pinning of supracondylar fracture in a child.
Supracondylar fracture of the humerus is the most common fracture of the elbow in children and has been treated by a variety of methods. Recently, stabilization of reduced fractures with percutaneous pin fixation has become the accepted method of treatment. Ulnar nerve injury is a complication of percutaneous pinning of supracondylar fractures, although many authors have reported that it resolves spontaneously after removal of the pin.

Clinical Trial Controlled Clinical TrialPatient-controlled lidocaine analgesia for acromioplasty surgery.
Twenty-four consecutive patients undergoing shoulder acromioplasty were given postoperative analgesia with a new method in which a patient-controlled continuous infusion of lidocaine infiltrated the subacromial space. Seventeen of the acromioplasties were done with arthroscopy, whereas 7 were performed with an open procedure. A 2% solution of lidocaine without epinephrine was used for both a continuous dose of 2 cc/h and patient-controlled interval doses of 1 cc administered at 15-minute intervals. ⋯ Blood levels of lidocaine averaged 0.3 microgram/mL in the 12 patients studied. Subjective pain levels and the amount of supplementary pain medication used were both lower in the group receiving patient-controlled lidocaine analgesia at statistically significant levels (P = .168 measuring subjective pain level, and P = .0212 measuring supplementary pain medication use). Patient-controlled lidocaine analgesia in the subacromial space appears to be a safe method for achieving high levels of pain control in patients undergoing an acromioplasty.

The glenoid articular surface is best studied radiographically on a tangential projection with both true anteroposterior and axillary views. Forty-one dry scapulas were studied under fluoroscopy to define the axillary projection that would provide a true scapular lateral view. The superior and inferior articular margins were marked with radiopaque solder wires. ⋯ X-ray films taken of another 8 cadaver shoulders were used to study the position of screws inserted about the glenoid articular surface. The soft tissue shadow superimposition on the inferior glenoid margin can lead to a misinterpretation of the superior margin as the whole glenoid articular surface. Because soft tissue can interfere with the appreciation of the glenohumeral joint line on an axillary view, a projection that will show a continuous line of the coracoid and glenoid articular surface should be obtained, and it will indicate a tangential view of the joint.
