Prospective Study of Arthrodesis of Finger Distal Interphalangeal Joints Using the Kerifuse Device

Arthrodesis of a distal interphalangeal joint of the finger (DIP) is mainly performed for a degenerated and painful joint. Various stabilization methods have been used to provide compression at the arthrodesis site such as pins, steel wires, compression screws, headless compression screws, bioresorbable implants and intramedullary staples. Although with complications such as implant fractures or dorsal cortical erosion, intramedullary arthrodesis staples provide reliable pain relief and a consistent fusion rate while inevitably scarring the finger pulp or nail dystrophy. The aim of this study is to evaluate the bone fusion time during an arthrodesis performed with the Kerifuse shape memory implant.

Denervation for Osteoarthritis in the PIP-joint Efficacy Study (DOPS)

The goal of this clinical trial is to compare the effects of a surgical and a non-surgical treatment method in patients with osteoarthritis in the proximal interphalangeal (PIP) joint. The main questions it aims to answer are: * Are the treatments effective? * Is the surgical treatment more effective than the non-surgical treatment? Participants will receive surgical treatment (PIP joint denervation) or non surgical treatment (patient education plus exercise). Researchers will compare the non-surgical and surgical groups to see if pain, patient-reported function, quality of life, movement and grip strength differs between the groups.
