The aim of this study is to assess outcomes of a lateral surgical approach for proximal interphalangeal joint arthroplasty with NeuFlex ® silicone implants for primary degenerative osteoarthritis. We reviewed 51 arthroplasties performed on 43 patients. The mean follow up period was 36 months (range 18-42). The average preoperative range of motion (ROM) was 38°. The average postoperative ROM was 63°. In 21/51 (41%) cases, there was an average axial deviation of 17° (range 10-30°). VAS and Quick DASH scores improved. In 5/51 (10%) cases, further surgery was required. Our lateral approach seems to be effective and minimally invasive, providing adequate exposure. Contralateral incision and contralateral ligament reinforcement should be performed, whenever necessary, to improve lateral stability.
