Continuous Compression Implants in Foot and Ankle Surgery: Tips and Tricks

Background: Continuous Compression Implants (CCIs) are low-profile implants made of nitinol and titanium. They offer multiple benefits in comparison to plate and screw fixation for foot and ankle indications, and they are designed in such a way that they continuously and dynamically compress the opposed bony surfaces throughout the entire healing process. Methods: In this study, we present our experience on the use of those nitinol implants for midfoot and hindfoot surgery. Furthermore, we elaborate on the advantages and downsides of using this internal fixation method and highlight common pitfalls which could lead to undesirable clinical outcomes. We also demonstrate our proposed surgical technique on how to use CCIs in a reproducible and reliable way and present surgical tips which could help reduce surgical time when utilising these implants. We also make surgical recommendations on their use and present the underlying biomechanics, which could provide a better understanding of the rationale behind using them in the field of foot and ankle surgery. Last but not least, we presented the early clinical and radiological results of a series of patients who underwent primary midfoot fusion for Lisfranc injury between 2020 and 2023. Results: With a minimum follow-up of 9 months, satisfactory clinical and radiological union was noted in all those patients. The mean difference between pre- and post-operative MOxFQ scores was -37.7 (95% CI was 16.9 to 58.5; p = 0.03). The mean post-operative VAS pain at rest was 3.2 (SD = 2.3). No major complications were noted. Conclusions: CCI internal fixation is a safe, reproducible, and reliable method when it comes to foot and ankle conditions, but it requires appropriate pre-operative planning, surgical training, and careful implantation

Osteochondral Autologous Transplantation Versus Dorsal Closing Wedge Metatarsal Osteotomy for the Treatment of Freiberg Infraction in Athletes: A Randomized Controlled Study With 3-Year Follow-up

Background:Dorsiflexion closing wedge metatarsal osteotomy (DCWMO) has been considered the traditional treatment of Freiberg disease. Several case reports presented osteochondral autologous transplantation (OAT) as an alternative treatment.Purpose/Hypothesis:The purpose was to compare the results of DCWMO versus OAT for the treatment of Freiberg infraction in an athletic population. It was hypothesized that OAT was superior to DCWMO regarding functional outcomes, pain, and the time that the athletes returned to training and to previous sport level.Study Design:Randomized controlled trial; Level of evidence, 2.Methods:Between 2008 and 2013, 27 consecutive patients with Freiberg disease were randomly assigned to either the DCWMO group (14 patients) or the OAT group (13 patients). The primary outcomes collected were as follows: postoperative complications, range of motion of the metatarsophalangeal joint, length of the metatarsal, function of the foot (measured with the American Orthopaedic Foot and Ankle Society–lesser metatarsophalangeal-interphalangeal [AOFAS-LMI] score), and pain (assessed with the visual analog scale–foot and ankle score).Results:Mean follow-up was 46 months (range, 36-60 months). The mean ± SD AOFAS-LMI score in the DCWMO group was 63.4 ± 14.4 preoperatively, 81.8 ± 6.6 at 1 year postoperatively, and 84.4 ± 5.6 at 3 years postoperatively, while in the OAT group, it was 62.8 ± 14, 89.9 ± 7.1, and 92 ± 6.9, respectively ( P &lt; .001). The differences in the AOFAS-LMI scores favoring the OAT group at 1 and 3 years reached statistical but not clinical significance. The mean visual analog scale–foot and ankle score was improved significantly from 48.1 ± 11.5 to 91.8 ± 9.5 in the DCWMO group and from 49.9 ± 10.9 to 95.4 ± 4.4 in the OAT group. There was a shortening of the metatarsals by a mean 1.9 ± 0.5 mm in the DCWMO group, as opposed to a metatarsal lengthening of 0.2 ± 0.1 mm in the OAT group. In the OAT group, patients were able to start training at 6 ± 1 weeks ( P &lt; .001) and return to full sport action at 10 ± 2.5 weeks ( P &lt; .05), while in the DCWMO group, the time was 8 ± 1.5 and 13 ± 2.5 weeks, respectively.Conclusion:The authors concluded that OAT is equal to DCWMO. Acceptable clinical results were reported, as well as very low morbidity and early return to sport activities. That makes the OAT procedure a safe, effective, and optimal treatment for an athletic population experiencing Freiberg infraction.</jats:sec

Intratendinous Ganglion Cyst of the Hand: A Case Report and Review of the Literature

Intratendinous ganglion of the hand is an extremely rare benign tumor, and only few cases have been reported so far in the literature. We present a case with an intratendinous ganglion of the extensor digitorum communis that treated with en bloc resection and subsequent tendon repair. According to the review of the literature and published data, the ganglion is predominantly located at hand extensor tendons (82%), and it is more frequent among females (75%) and shows a high incidence in 5th and 6th decades of life (94.5%). Surgical excision with or without side-to-side repair and/or tendon transfer leads to excellent outcome and low potential for recurrence
