“…The radiographic fusion rate of 88% at 26 weeks’ follow-up with the fiber-reinforced implant is consistent with the higher end of published fusion rates for other intramedullary PIP joint implants. 2,9,10,12,16 -18,22,23,26,27,34,35,39 -42,45 Three studies of absorbable intramedullary implants in PIP joint arthrodesis reported fusion rates of 79%, 26 83%, 27 and 85%. 45 In 8 studies of intramedullary nitinol implants for PIP joint arthrodesis to correct hammertoe deformity, fusion rates ranged from 44% 34 to 100%, 2 and averaged around 79%.…”

Background: A novel biointegrative implant was developed for proximal interphalangeal joint (PIPJ) arthrodesis to treat hammertoe deformity. Composed of continuous reinforcing mineral fibers bound by bioabsorbable polymer matrix, the implant demonstrated quiescent, gradual degradation with complete elimination at 104 weeks in animal models. This prospective trial assessed the implant’s safety, clinical performance, and fusion rate of PIPJ arthrodesis for hammertoe correction. Methods: Twenty-five patients (mean age 63.9±7.5 years) who required PIPJ arthrodesis were enrolled at 3 centers. Outcomes included radiographic joint fusion, adverse events, pain visual analog scale (VAS) score, Foot and Ankle Ability Measure (FAAM) Activities of Daily Living (ADL) score, and patient satisfaction. Patients were evaluated 2, 4, 6, 12, and 26 weeks postoperatively. Results: Twenty-two patients (88%) achieved radiographic fusion at 26 weeks. All joints (100%) were considered clinically stable, with no complications or serious adverse events. Pain VAS improved from 5.3±2.5 preoperatively to 0.5±1.4 at 26 weeks postoperatively. FAAM-ADL total scores and level of functioning improved by mean 19.5±19.0 points and 24.4±15.7 percentage points, respectively, from preoperation to 26 weeks postoperation. Improvements in pain VAS and FAAM scores surpassed established minimal clinically important differences. All patients were very satisfied (84%) or satisfied (16%) with the surgery. Patient-reported postoperative results greatly exceeded (72%), exceeded (20%), or matched (8%) expectations. Conclusion: This prospective, multicenter, first-in-human clinical trial of a novel biointegrative fiber-reinforced implant in PIPJ arthrodesis of hammertoe deformity demonstrated a favorable rate of radiographic fusion at 12 and 26 weeks, with no complications and good patient-reported clinical outcomes. Level of Evidence: Level IV, prospective case series.

“…Thus, it is imperative to have everything ready beforehand. 15 Scholl et al 28 hypothesized that another possible reason for Smart Toe breakage could be the length of the selected With regards to the K-wire, arguments against its use typically focus on complications associated with the pins. Pin-tract infection is the most commonly cited pin-related complication.…”

“…29 Many studies argue that intramedullary implants reduce K-wire complications. 1,7,[14][15][16] The aim of this study was to analyze functional outcomes in patients who had undergone proximal interphalangeal joint fusion using 2 types of intramedullary implants, the Smart Toe and the TenFuse, and to compare them with the outcomes in patients treated with standard K-wire temporary fixation. The hypothesis was that intramedullary implants would offer superior fixation, less pain, fewer complications, and superior rates of arthrodesis than K-wires.…”

The pathology and management of lesser toe deformities

Deformities of the lesser toes are common and can be associated with significant morbidity. These deformities are often multiple, and numerous treatment strategies have been described in the literature.The goal of surgical treatment is to improve symptoms by restoring alignment and function, and avoiding recurrence. In order to achieve this, it is essential for the treating surgeon to understand the normal anatomy and pathology of the various deformities.There is a paucity of prospective studies and randomisedcontrolled trials assessing the efficacy of specific interventions.We describe the normal anatomy and biomechanics of the lesser toes, and the pathology of commonly adult deformities. The rationale behind various treatment strategies is discussed and the results of published literature presented. Algorithms for the management of lesser toe deformities based on current literature are proposed.
