Fixation of fractures of the proximal humerus with the PlantTan Humerus Fixator Plate: early experience with a new implant.
The majority of fractures of the proximal humerus can be managed nonoperatively. However, displaced fractures generally require operative repair, and in the young patient with good bone quality, the results are usually satisfactory. In contrast, the osteoporosis found in the elderly patient makes internal fixation problematic and frequently contributes to failure of fixation and poor results. ⋯ In 3 of 7 patients, all under 65 years of age, the results were good. However, in the remaining 4 patients, all over the age of 75 years, there was a 100% failure rate, with screw penetration of the head in 3 patients and secondary displacement of the fracture at 7 days postoperatively in another. We conclude that this implant is unsatisfactory for patients with osteopenic bone in the humeral head.

Glenohumeral joint translation after arthroscopic thermal capsuloplasty of the rotator interval.
The treatment of recurrent anterior, posterior, or multidirectional glenohumeral instability by operative closure of the rotator interval has been proposed. The purpose of this study was to determine whether arthroscopic thermal capsuloplasty of the rotator interval with the radiofrequency probe significantly decreases anterior-posterior glenohumeral translation. Anterior and posterior loads of 10, 15, and 20 N were sequentially applied to 8 cadaveric shoulder joints while mounted in a translation testing apparatus with an electromagnetic tracking device measuring anterior and posterior glenohumeral translation. ⋯ The results of this study indicate that arthroscopic thermal capsuloplasty of the rotator interval is an effective way by which to decrease both anterior and posterior glenohumeral translation in vitro. To date, no in vivo studies that sufficiently document long-term clinically successful outcomes of such a procedure exist. Future studies are warranted to evaluate the effects of the biologic response to thermal shrinkage and whether these reduced glenohumeral translations will be maintained.

Patients' preoperative expectations of shoulder surgery affect both the decision to proceed with surgery and how patients assess outcomes of surgery. Our goals were to identify patients' expectations of shoulder surgery, to develop and test a patient-derived shoulder surgery expectations survey, and to determine the prevalence of major expectations by diagnosis. An initial sample of 409 patients (mean age, 51 +/- 17 years; 58% men) with diverse shoulder diagnoses were asked open-ended questions preoperatively about their expectations of shoulder surgery. ⋯ Items retained to form the final survey were frequently cited, represented clinically relevant or potentially unrealistic expectations, and had concordance levels of 0.40 to 0.83 measured by the kappa statistic (71% had kappa >or= 0.60). The final 17-item Hospital for Special Surgery Shoulder Surgery Expectations Survey requires less than 5 minutes to complete. This patient-derived, self-administered survey has several possible uses in daily clinical practice, such as providing a way to learn about the patient's perspectives, providing the orthopaedist with a template to guide a formal discussion about realistic and unrealistic goals, and providing a prospective record that can be used jointly by the orthopaedist and patient postoperatively to assess the outcome of surgery.
