“…The utilization of this guide exhibited a statistically significant reduction in intraoperative duration by 26 minutes, diminished intraoperative hemorrhagic losses by 23 %, and expedited attainment of osteosynthesis when compared to conventional surgical methods. Notably, when scrutinizing parameters such as postoperative range of motion and complications, there was a lack of statistically significant disparity between osteotomies executed by seasoned orthopedic surgeons and those guided by 3D-printed templates (36).…”

Background: Musculoskeletal abnormalities are estimated to be 21.1% of all birth defects, if left untreated such defects represent high morbidity in patients. Advances in biomedical technologies such as prosthetics and 3D printing can further improve treatment in orthopedics and enhance patient’s quality of life. The aim of this paper is to review the literature in search of the state of the art in 3D printing related to orthopedics and musculoskeletal birth defects.Methods: A comprehensive literature search was performed in indexed databases. Keywords included: orthopedics,”, “3d printing”, “congenital”, “malformations”, “defects” and “treatment”. A total of 29 articles were suitable for the subject matter and included for this review.Results and Discussion: 3D printing allows a better surgical planning in the orthopedic field as it can be used as a surgical guide or for creating custom 3D-printed tools, devices, patient-specific prostheses, and implants. Also, complex limb malformations can be modeled, and further 3D printed to accurately understand, study, and plan a surgical approach. Scaffold and bio-ink for 3D bioprinters can also be capable of developing bone and cartilage suitable for complex orthopedic and pediatric remodeling. Conclusion: 3D printing in orthopedics and musculoskeletal birth defects is an important and innovative subject, as it allows to make better surgical approaches and supply the structural function of the original malformed tissue.

“…Moreover, the coverage of soft tissue defects in limbs involves several techniques ranging from the simple second-intention healing to skin grafting with or without dermal substitutes, to local homodigital or heterodigital flaps and partial toe transfers, and the arsenal in terms of skin coverage and especially flaps is diverse [ 9 , 10 ]. Thus, successful and timely treatment and management are significant [ 11 – 13 ]. Otherwise, it is easy to produce a series of complications, such as wounds infection, scar contracture, and dysfunction of functional activity at wound sites, and serious cases may eventually result in disability, which might cause huge psychological and economic burden to patients and reduce the quality of life [ 14 , 15 ].…”

Objective Currently, among wounds with large skin tissue defects caused by various reasons, the treatment of refractory wounds is still a major clinical problem. This study is aimed to preliminarily assess the therapeutic potentials of platelet-rich plasma (PRP) in refractory wounds with exposed tendons, as well as corresponding efficacy and safety. Methods A total of 12 patients (5 males and 7 females) with refractory wounds and exposed tendons who were admitted to our hospital from June 2018 to December 2020 were included in this study. After the preparation of PRP, the included patients underwent the PRP injection after the debridement of wounds, and the efficacy and prognosis were assessed by the same group of senior surgeons. Results The average age of included patients was 42.7 ± 12.9 years, and the causes of injury included traffic accidents (3 cases), contusion (2 cases), burns (2 cases), diabetes complications (4 cases), and melanoma complications (1 cases). The average healing time was 23.0 ± 5.0 days, and the mean size of the wound was 3.1 × 5.1 cm2. During the whole treatment process, Vancouver Scar Scale (VSS) decreased from 7.4 ± 1.6 before PRP treatment to 3.6 ± 0.9 after treatment (P < 0.001), Manchester Scar Scale (MSS) decreased from 12.3 ± 4.5 before PRP treatment to 5.4 ± 1.2 after treatment (P < 0.001), and no redness and swelling were observed around wounds, the size and degree of wounds gradually reduced, the coverage rate of granulation tissue was acceptable, overall quality of scar was relatively good, skin sensitivity around wounds was normal, there was no local wounds secretion, and postoperative patient's satisfaction was relatively good during follow-up. Conclusions Our study has preliminarily indicated that PRP can promote the wounds healing, reduce the inflammation around wounds, and improve the granulation tissue and angiogenesis, thereby effectively polishing up the safety and efficacy.

Background The orthopedic treatment of the stiff clubfoot is challenging for clinicians, and the purpose of this study was to explore the preliminary findings of 3D printing-assisted patient-specific instrument (PSI) osteotomy guide for use in the orthopedic treatment of the stiff clubfoot. Material and methods There were 20 patients (25 feet) with stiff clubfoot admitted from December 2018 to June 2022, including 13 males (16 feet) and 7 females (9 feet), aged 24–52 years, mean 40.15 years; 8 left feet, 7 right feet, 5 bipedal. All patients underwent triple arthrodesis and were divided into 10 cases (12 feet) in the PSI group (n = 12) and 10 cases (13 feet) in the conventional surgery group (n = 13) according to the surgical approach. The duration of surgery and the number of radiation exposures were recorded in all cases, and the American Orthopedic Foot and Ankle Society (AOFAS), and International Congenital Clubfoot Study Group (ICFSG) scoring systems were applied postoperatively to assess the effect of corrective treatment. All measurement data were expressed as mean ± standard deviation, and differences between groups were determined by Student’s t test. All count data between the two groups were compared using the chi-square test or Fisher’s exact test analysis. Results All 20 patients (25 feet) were followed up for 1 year. No major complications related to osteotomy, such as overcorrection, incomplete correction, or bone nonunion, were observed in the PSI and conventional surgery groups at the final follow-up, and the PSI group had the advantage of shorter operative time (P < 0.01), less radiation exposure (P < 0.01), and higher excellent rate compared with the conventional surgery group. The AOFAS score (P > 0.05) and ICFSG score (P > 0.05) at the last follow-up were not statistically significant in both groups, but the excellent rate at the last follow-up was 91.7% in the PSI group which was significantly higher than that of the conventional surgery group at 76.9%. Conclusions The utilization of 3D printing-assisted PSI osteotomy guide in orthopedic surgery for stiff clubfoot offers a safe and effective surgical tool for triple joint fusion treatment. This technology simplifies surgical procedures, minimizes intraoperative radiation exposures, reduces surgical time, and enables precise and personalized treatment.
