Pseudotumor formation and serum ions after large head metal-on-metal stemmed total hip replacement. Risk factors, time course and revisions in 706 hips.
The incidence and natural course of pseudotumors in metal-on-metal total hip arthroplasties is largely unknown. The objective of this study was to identify the true incidence and risk factors of pseudotumor formation in large head metal-on-metal total hip arthroplasties. ⋯ This study confirms a high incidence of pseudotumors, dramatically increasing after prolonged follow-up. Risk factors for pseudotumors are of limited importance. Pain was the strongest predictor for pseudotumor presence; cobalt chromium and swelling were considered poor predictors. Cross-sectional imaging is the main screening tool during follow-up.

Update TFCC: histology and pathology, classification, examination and diagnostics.
The TFCC is a crucial stabilizer of the DRUJ. Based on its superficial and deep fibers, the TFCC guarantees unrestricted pronation and supination which is essential for performing sophisticated tasks. The ability to perform complex movements is of uppermost importance for hand function. ⋯ Therefore, a thorough clinical examination is not dispensable. Wrist arthroscopy remains the "gold standard" for diagnosing TFCC pathologies despite technical progress in imaging modalities. MR arthrography may have the potential to become a real alternative to wrist arthroscopy for diagnosing TFCC pathologies with technical progress in the future.

Randomized Controlled Trial Comparative StudyComparison of novel intramedullary nailing with mini-invasive plating in surgical fixation of displaced midshaft clavicle fractures.
This prospective randomized pilot study sought to determine whether fixation with Sonoma CRx intramedullary pin is a comparable alternative to minimally invasive plating fixation in patients with displaced clavicle fractures. ⋯ Given the shorter operative times and better cosmetic appearance, Sonoma CRx intramedullary pin may be an alternative to minimally invasive plating. Further safety studies are warranted.

Structural and clinical integrity of the rotator cuff in athletes after arthroscopic Bankart repair using the three-portal technique.
Muscular recovery of structural integrity after arthroscopic Bankart repair using the para- and trans-musculotendinous three-portal technique has not been investigated. ⋯ Arthroscopic Bankart repair using the three-portal technique prevents full muscular integrity for para-tendinous anteroinferior portals at the SSC, the trans-tendinous suprabicipital portal through the SSP, and the trans-tendinous portal through the ISP.

Comparative StudyComparison of Bryan versus ProDisc-C total disk replacement as treatment for single-level cervical symptomatic degenerative disk disease.
The purpose of this retrospective trial was to compare the role of the Bryan with ProDisc-C total disk replacement (TDR). ⋯ Both the Bryan and the ProDisc-C TDR resulted in satisfactory clinical outcome. Moreover, Bryan TDR can maintain the lordosis of FSU, whereas ProDisc-C TDR can restore the lordosis of FSU, whether or not this radiographic evidence leads to more favorable clinical outcome for ProDisc-C TDR requires further investigation.
