Background: The purpose of this study was to describe the natural history of Kienböck disease among patients who elected to proceed with nonoperative treatment. Methods: The authors performed a retrospective study of all patients treated nonoperatively for Kienböck disease within their institution from January 1, 1999, to December 31, 2014. Inclusion criteria included follow-up greater than 1 year, serial posteroanterior and lateral wrist radiographs, and clinical examination. Posteroanterior/lateral radiographs were independently reviewed at initial presentation and at final follow-up, including Lichtman stage, carpal index, Stahl index, ulnar variance, and intercarpal angles. Results: Twenty-five patients with 25 wrists were included (mean age, 50.2 years), with an average length of clinical follow-up of 3.9 years and a mean length of radiographic follow-up of 5.2 years. There was no significant difference in range of motion; however, patient-reported pain was significantly decreased, and modified Mayo wrist scores and grip strength were increased. Lichtman stage, scapholunate angle, and radioscaphoid angle were increased; and carpal index, posteroanterior lunate ratio, and Stahl index were decreased across the study period. The mean progression in Lichtman stage was 0.5 stage/year with a range of 0 to 1.6 stages/year throughout the study period. There was no significant difference in Lichtman stage progression based on stage at presentation. A history of smoking was associated with increased radiographic disease progression. Conclusion: The present study demonstrates that among patients with Kienböck disease managed nonoperatively, the majority of patients significantly improve over time with respect to pain, grip strength, and Mayo wrist score, despite radiographic progression of disease. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, IV.

Background: We sought to compare the functional outcomes, radiographic outcomes, and complications of trapeziectomy and flexor carpi radialis (FCR) to abductor pollicis longus (APL) side-to-side tendon transfer with or without suture-button suspensionplasty for thumb basilar joint arthritis. Methods: Patients treated with and without suture-button suspensionplasty were compared over a 6-year period. Data were reviewed for complications and functional outcomes, including grip and pinch strength, range of motion, and visual analog scale (VAS) pain scores. Plain radiographs were independently reviewed at initial presentation and at final follow-up, including proximal phalanx length, trapezial space height, and trapezial height ratio. Results: Seventy thumb arthroplasties were performed in 70 patients. Trapeziectomy with FCR-APL side-to-side tendon transfer was performed in 39 patients, and trapeziectomy with FCR-APL side-to-side tendon transfer with suture-button suspensionplasty was performed in 31 patients. Mean length of follow-up was 28.4 ± 3.9 and 23.8 ± 2.6 months, respectively. Postoperative grip, oppositional and appositional pinch strength, and VAS pain scores improved compared with preoperative values, but were not significantly different based on suture-button suspensionplasty. Percentage decline in trapezial space ratio was significantly different between groups at 36.7% and 20.4% for procedures with and without suture-button suspensionplasty, respectively indicating that the trapezial space was better maintained within the suture suspension cohort. The incidence of postoperative complications, including surgical site infection, paresthesias, reoperation, complex regional pain syndrome, and symptomatic subsidence, was not significantly different between groups. Conclusions: Trapeziectomy with FCR to APL side-to-side tendon transfer with and without suture-button suspensionplasty results in comparable improvement in pain, grip strength, and functional parameters. Suture-button suspensionplasty results in significantly greater preservation of trapezial space.

Abstract Objective To determine the prognosis of patients with non‐secretory myeloma. Methods We studied 124 patients diagnosed with multiple myeloma who had no monoclonal protein detected on serum and urine immunofixation at diagnosis and on all subsequent follow‐up testing (non‐secretory myeloma). The overall survival ( OS ) of patients with non‐secretory myeloma was compared with 6953 patients with typical myeloma seen during the same time period in whom a monoclonal protein was detected at the time of diagnosis. Results One hundred and twenty‐four patients met criteria for non‐secretory multiple myeloma. The median follow‐up was 102 months (range, 1–204 months). The median progression‐free survival with initial therapy was 28.6 months, and the median OS was 49.3 months. There was a significant improvement in OS since 2001; median survival 43.8 months (prior to 2001) vs. 99.2 months (2001–2012), P < 0.001. OS was superior in patients with a normal baseline FLC ratio ( n = 10) compared to patients with an abnormal ratio ( n = 19), medians not reached in both groups. Prior to 2001, OS was similar in non‐secretory myeloma ( n = 86) and secretory myeloma ( n = 4011), median 3.6 vs. 3.5 yr, respectively, P = 0.63. However, among patients diagnosed between 2001 and 2012, OS was superior in non‐secretory myeloma ( n = 36) compared to secretory myeloma ( n = 2942), median 8.3 vs. 5.4 yr, respectively, P = 0.03. Conclusions Non‐secretory myeloma is an uncommon subtype of multiple myeloma. In the last decade, there has been an improvement in the survival of non‐secretory myeloma and appears superior to secretory myeloma.
