An alternative treatment option for scaphoid nonunion advanced collapse (SNAC) and radioscaphoid osteoarthritis: early results of a prospective study on the pyrocarbon adaptive proximal scaphoid implant (APSI).

Introduction: Scaphoid nonunion advanced collapse (SNAC) and radioscaphoid osteoarthritis are difficult to treat. Options include proximal row carpectomy (PRC), four corner fusion (4CF) and wrist arthroplasty or arthrodesis. However, with inevitable disease progression, a significant proportion of patients undergo total wrist fusion.

Early results of a prospective study on the pyrolytic carbon (pyrocarbon) Amandys® for osteoarthritis of the wrist.

Introduction: The preliminary results of a pyrocarbon interpositional radiocarpal implant in a small cohort of patients were reviewed. As it is currently only a limited release product, we describe to potential users early complications and negative outcomes.

Methods: Patients were assessed using pain levels, ranges of motion, grip strength, type of and time to return to work as well as pre-operative and post-operative DASH (Disabilities of the Arm, Shoulder and Hand) scores.

Immediate unprotected weight-bearing of operatively treated ankle fractures.

The objective of this study was to determine whether immediate mobilisation and unprotected weight-bearing of rigidly internally fixed fractured ankles had a significant effect on ankle function or whether it predisposed the ankle to loss of reduction or hardware failure. Twenty five patients with operated Weber A/B/C fractures were allowed immediate full weight-bearing without a plaster and were compared with matched historical controls treated in a non-weight-bearing plaster cast. Matched-pair analysis revealed no differences for hospital stay and functional outcome on Olerud and Molander scoring system but significant difference in time until return to work (mean: 91.
