Comparison of Intact Fish Skin Graft and Allograft as Temporary Coverage for Full-Thickness Burns: A Non-Inferiority Study.

The extent and depth of burn injury may mandate temporary use of cadaver skin (allograft) to protect the wound and allow the formation of granulation tissue while split-thickness skin grafts (STSGs) are serially harvested from the same donor areas. However, allografts are not always available and have a high cost, hence the interest in identifying more economical, readily available products that serve the same function. This study evaluated intact fish skin graft (IFSG) as a temporary cover to prepare the wound bed for STSG application. Thirty-six full-thickness (FT) 5 × 5 cm burn wounds were created on the dorsum of six anesthetized Yorkshire pigs on day -1. To mimic the two-stage clinical situation, on day 0, wounds were excised down to a bleeding wound bed and a temporary cover (either IFSG or cadaver porcine skin) was applied; then, on day 7, wounds were debrided to a viable wound bed prior to the application of autologous 1.5:1 meshed STSG (mSTSG). Rechecks were performed on days 14, 21, 28, 45, and 60 with digital images, non-invasive measurements, and punch biopsies. The IFSG created a granulated wound bed receptive to the application of an mSTSG. FT burn wounds treated with an IFSG had similar outcome measures, including contraction rates, trans-epidermal water loss (TEWL) measurements, hydration, and blood perfusion levels, compared to cadaver skin-treated burn wounds. Pathology scoring indicated significant differences between the allograft- and IFSG-treated wounds on day 7, with the IFSG having increased angiogenesis, granulation tissue formation, and immune cells. Pathology scoring indicated no significant differences once mSTSGs were applied to wounds. The IFSG performed as well as cadaver skin as a temporary cover and was not inferior to the standard of care, suggesting the potential to transition IFSGs into clinical use for burns.

Safety and Efficacy of Autologous Cartilage Graft in Augmentation Rhinoplasty.

Augmentation rhinoplasty or commonly known as "nose jobs" is one of the most common plastic surgical procedures aimed to improve cosmetic appearance. This procedure is considerably safer, less time consuming with faster recovery and immediate cosmetic effect. This procedure needs of highly experienced and well-trained plastic surgeon. According to facial analysis you can select the type of rhinoplasty. Open discussion with the patient to select appropriate surgical technique and its possible risks with your plastic surgeon to ensure the highest level of safety and satisfaction. Autologous grafting materials are safe, efficient and also the first choice for rhinoplasty due to it can survive without a vascular supply, the resorption rate of cartilage is much lower than that of a bone graft. Autologous grafting materials are stable and resistant to infection and extrusion over time so, they are successfully used for dorsal augmentation. To perform successful augmentation rhinoplasty, surgeons should be highly experienced and well-trained and augmentation materials that are currently available and understand their risks, benefits and uses. Autologous cartilage graft regarded as the graft of choice in augmentation rhinoplasty because of their lower rate of infection, rejection, resorption, extrusion, donor site morbidity, easy reshaping.

Portal vein wedge resection and patch venoplasty with autologous vein grafts for hepatobiliary-pancreatic cancer.

BACKGROUND: Advanced hepatobiliary-pancreatic cancer often invades critical blood vessels, including the portal vein (PV) and hepatic artery. Resection with tumor-free resection margins is crucial to achieving a favorable prognosis in these patients. Herein, we present our cases and surgical techniques for PV wedge resection with patch venoplasty using autologous vein grafts during surgery for pancreatic ductal adenocarcinoma (PDAC) and perihilar cholangiocarcinoma (PhCC). CASE PRESENTATION: Case 1: 73-year-old female patient with PDAC; underwent subtotal stomach-preserving pancreatoduodenectomy, with superior mesenteric vein wedge resection and venoplasty with the right gonadal vein. Case 2: 67-year-old male patient with PDAC; underwent distal pancreatectomy and celiac axis resection, with PV wedge resection and venoplasty with the middle colic vein. Case 3: 51-year-old female patient with type IV PhCC; underwent left hepatectomy with caudate lobectomy and bile duct resection, with hilar PV wedge resection and venoplasty with the inferior mesenteric vein (IMV). Case 4: 69-year-old male patient with type IIIA PhCC; underwent right hepatopancreatoduodenectomy, with hilar PV resection and patch venoplasty with the IMV. All patients survived for over 12 months after the surgery, without local recurrence. CONCLUSIONS: PV wedge resection and patch venoplasty is a useful technique for obtaining tumor-free margins in surgeries for hepatobiliary-pancreatic cancer.

[Comparison of clinical outcomes of anterior cruciate ligament repair in the active military using allograft versus autograft, 2-year follow-up]. / Comparación de resultados clínicos de reparación de ligamento cruzado anterior en militares en el activo con uso de aloinjerto versus autoinjerto, seguimiento de 2 años.

INTRODUCTION: Due to the inherent activities of the active duty personnel of the Mexican Navy, ligament injuries are constant, particularly the anterior cruciate ligament of the knee (ACL). Currently, we have various techniques and resources for its repair. OBJECTIVE: identify the clinical results obtained in anterior cruciate ligament reconstruction in active military. MATERIAL AND METHODS: retrospective observational study comparing clinical outcomes of anterior cruciate ligament repair in active military with the use of allograft and autograft in 23 patients who met inclusion criteria for the surgical procedure from 2017 to 2019 at the Naval Medical Center. 23 patients (46 in total) were considered for each category of anterior cruciate ligament repair with autologous graft (contralateral patellar) and heterologous graft (cadaveric anterior cruciate ligament). With an average age of autologous (35.6 years), heterologous (35 years). BMI average: autologous (26.5), heterologous (26.5). Male gender in its entirety. The IKDC and Lysholm scales were applied to all patients for the evolution of subjective results of clinical improvement in a 2-year follow-up; where a significant difference (p = 0.0001) could be observed when comparing both anterior cruciate ligament reconstruction techniques. RESULTS: we included 46 patients who underwent anterior cruciate ligament reconstruction for indication of complete injury respectively by the Joint Surgery Service of the Naval Medical Center. A better level of clinical benefit was observed in patients with heterologous graft, both in evaluation by IKDC scale (median 95.52 ± 1.85) as in Lysholm scale (median 94.91 ± 1.62) compared to autologous grafts, IKDC (median 89.92 ± 2.55) and Lysholm (median 86.04 ± 5.58), with value of p = 0.0001 for both cases. CONCLUSIONS: The results our study suggests that a superiority of functionality is obtained as reported by patients in whom heterograft was used.

DALK combined intralamellar tectonic patch graft: an alternative approach to treat frank corneal perforation.

BACKGROUND: Deep anterior lamellar keratoplasty (DALK) has gained popularity in cases of corneal thinning and leaking descemetocele. In this study, we introduced an intralamellar tectonic patch graft in addition to conventional DALK procedures to treat frank cornea perforation. METHODS: This retrospective case series included 13 patients (13 eyes) with frank corneal perforations who underwent DALK combined with intralamellar tectonic patch graft between December 2015 and December 2021. In addition to the standard DALK procedure, the perforation site was repaired with an extra intralamellar tectonic patch graft. The collected data included patient demographics, aetiology, size and location of the corneal perforation, visual acuity, surgical details, and postoperative complications. RESULTS: Seven patients underwent autologous intralamellar patch grafts, whereas six received allogeneic ones. Anatomical success was achieved in all patients. The mean postoperative follow-up was 33.31 ± 25.96 months (6-73 months). The postoperative visual acuity (0.90 ± 0.65 logMAR) was significantly improved (P = 0.003) compared to the preoperative score (1.74 ± 0.83 logMAR). Best corrected visual acuity (BCVA) improved in 12 eyes (92.3%). The mean endothelial cell density was 2028 ± 463 cells/mm2, 6-12 months postoperatively. There was no recurrence of perforation, and the anterior lamellar graft remained transparent in 12 patients (92.3%). Postoperative complications included epithelial defects (23.1%), ocular hypertension (15.4%), and cataract (7.7%). CONCLUSIONS: DALK combined with intralamellar tectonic patch graft may serve as a secure and effective alternative in treating frank corneal perforation, with reduced complications compared to conventional penetrating keratoplasty.

Comparative analysis of cancellous graft and cortico-cancellous graft in osteosynthesis of scaphoid pseudoarthrosis with plate.

INTRODUCTION: Scaphoid is the most fractured carpal bone, with a 5-10% nonunion rate. Treatment challenges include choosing the implant and graft that best corrects humpback deformity and carpal malalignment with higher chances of bony healing. OBJECTIVE: Compare cortico-cancellous and cancellous grafts between two groups of patients treating scaphoid nonunion with locking plates using autologous bone graft and evaluate bone healing rates and radiographic, tomographic, and functional parameters before and after surgery. METHODS: Non-randomized prospective study including 20 cases of scaphoid nonunion. Groups were divided into Group A (ten patients treated with cortico-cancellous iliac graft) and Group B (ten patients treated with cancellous iliac graft). Patients underwent pre- and postoperative radiographs, computed tomography, and functional evaluation. RESULTS: In postoperative analysis, Group A showed a statistically significant difference in intrascaphoid angle (p = 0.002) and scapholunate angle (p = 0.011) correction when comparing the pre- and postoperative periods. Group B showed a statistically significant difference in intrascaphoid angle (p = 0.002) and scapholunate angle correction (p = 0.0018), grip strength (p = 0.002), and tip pinch strength (p = 0.001) when comparing the pre- and postoperative periods. By comparing both groups, Group B showed a statistically significant difference in intrascaphoid angle correction (p = 0.002), grip strength (p = 0.002), tip pinch strength (p = 0.002), and radial deviation (p = 0.0003). There was no statistical difference when comparing bony healing between groups. CONCLUSION: Scaphoid nonunion treatment with a locking plate was effective, showing a high bony healing rate and improved carpal alignment in imaging tests for both graft types. However, results for intrascaphoid angle correction, grip strength, tip pinch strength, and radial deviation were better in Group B. LEVEL OF EVIDENCE: IV, case series.

Comparison of oral morbidity and mid-term efficacy of anterior urethroplasty using an autologous tissue-engineered graft (MukoCell®) versus native oral mucosa graft.

OBJECTIVE: Our study aimed to compare surgical success rate (SR) and oral morbidity of augmentation urethroplasty for anterior urethral strictures using autologous tissue-engineered oral mucosa graft (TEOMG) named MukoCell® versus native oral mucosa graft (NOMG). METHODS: We conducted a single-institution observational study on patients undergoing TEOMG and NOMG urethroplasty for anterior urethral strictures >2 cm in length from January 2016 to July 2020. SR, oral morbidity, and potential risk factors of recurrence were compared between groups were analyzed. A decrease of maximum uroflow rate < 15 mL/s or further instrumentation was considered a failure. RESULTS: Overall, TEOMG (n = 77) and NOMG (n = 76) groups had comparable SR (68.8% vs. 78.9%, p = 0.155) after a median follow-up of 52 (interquartile range [IQR] 45-60) months for TEOMG and 53.5 (IQR 43-58) months for NOMG. Subgroup analysis revealed comparable SR according to surgical technique, stricture localization, and length. Only following repetitive urethral dilatations, TEOMG achieved lower SR (31.3% vs. 81.3%, p = 0.003). Surgical time was significantly shorter by TEOMG use (median 104 vs. 182 min, p < 0.001). Oral morbidity and the associated "burden" in patients' quality of life were significantly less at 3 weeks following the biopsy required for TEOMG manufacture, compared to NOMG harvesting and totally absent at 6 and 12 months postoperatively. CONCLUSIONS: The SR of TEOMG urethroplasty appeared to be comparable to NOMG at a mid-term follow-up but taking into account the uneven distribution of stricture site and the surgical techniques used in both groups. Surgical time was significantly shortened, since no intraoperative mucosa harvesting was required, and oral complications were diminished through the preoperative biopsy for MukoCell® manufacture.

Rehabilitation of Post-traumatic Anterior Maxillary Osseous Deficit Using Iliac Onlay Bone Graft Combined With Dental Implants.

Fracture of the anterior maxilla usually causes a scooped-out defect in this region which leads to loss of lip support and a sub-optimal condition for placement of implants. The iliac crest is a frequently used donor location in oral and maxillofacial procedures for bone augmentation in order to restore jaw deformities brought on by trauma or pathological diseases prior to the placement of dental implants. Here we present the case of a patient who had undergone reconstruction of the maxillary osseous defect caused due to trauma by iliac crest grafting, followed by placement of dental implants after six months.

Case report: Limb-sparing surgery of tibial chondrosarcoma with frozen autologous bone graft using liquid nitrogen in a dog.

Chondrosarcoma is the second most common primary bone tumor after osteosarcoma in dogs. Chondrosarcoma has a good prognosis owing to its low metastatic rate and long survival time, even with amputation alone. However, amputation risks reducing the quality of life in patients with other orthopedic diseases of the non-affected limb, neurological diseases, or large body size. Limb-sparing surgery with frozen autologous bone grafting using liquid nitrogen allows bone quality to be maintained in the normal bone area while killing tumor cells, thereby preserving the affected limb. Thus, it is expected to maintain the quality of life. We describe herein limb-sparing surgery for tibial chondrosarcoma with frozen autologous bone graft using liquid nitrogen in an 8-year and 8-month-old castrated male bulldog weighing 29.2 kg. The patient had chondrosarcoma of the left tibia, suspected cranial cruciate ligament rupture of the right stifle, and degenerative lumbosacral stenosis. In such a case, amputation would increase the burden on the non-affected limb or spine, which could cause difficulty in walking; therefore, we performed limb-sparing surgery. Postoperatively, although a circumduction gait associated with stifle arthrodesis remained, the patient maintained the quality of life for 20 months, and the owner was satisfied with the results.

Autologous Tooth Graft: Innovative Biomaterial for Bone Regeneration. Tooth Transformer® and the Role of Microbiota in Regenerative Dentistry. A Systematic Review.

Different biomaterials, from synthetic products to autologous or heterologous grafts, have been suggested for the preservation and regeneration of bone. The aim of this study is to evaluate the effectiveness of autologous tooth as a grafting material and examine the properties of this material and its interactions with bone metabolism. PubMed, Scopus, Cochrane Library, and Web of Science were searched to find articles addressing our topic published from 1 January 2012 up to 22 November 2022, and a total of 1516 studies were identified. Eighteen papers in all were considered in this review for qualitative analysis. Demineralized dentin can be used as a graft material, since it shows high cell compatibility and promotes rapid bone regeneration by striking an ideal balance between bone resorption and production; it also has several benefits, such as quick recovery times, high-quality newly formed bone, low costs, no risk of disease transmission, the ability to be performed as an outpatient procedure, and no donor-related postoperative complications. Demineralization is a crucial step in the tooth treatment process, which includes cleaning, grinding, and demineralization. Since the presence of hydroxyapatite crystals prevents the release of growth factors, demineralization is essential for effective regenerative surgery. Even though the relationship between the bone system and dysbiosis has not yet been fully explored, this study highlights an association between bone and gut microbes. The creation of additional scientific studies to build upon and enhance the findings of this study should be a future objective of scientific research.

Outcomes of surgical management and implant consideration for depressed skull fractures: A systematic review.

Background: Traumatic brain injuries (TBIs) are associated with high mortality and morbidity. Depressed skull fractures (DSFs) are a subset of fractures characterized by either direct or indirect brain damage, compressing brain tissue. Recent advances in implant use during primary reconstruction surgeries have shown to be effective. In this systematic review, we assess differences in titanium mesh, polyetheretherketone (PEEK) implants, autologous pericranial grafts, and methyl methacrylate (PMMA) implants for DSF treatment. Methods: A literature search was conducted in PubMed, Scopus, and Web of Science from their inception to September 2022 to retrieve articles regarding the use of various implant materials for depressed skull fractures. Inclusion criteria included studies specifically describing implant type/material within treatment of depressed skull fractures, particularly during duraplasty. Exclusion criteria were studies reporting only non-primary data, those insufficiently disaggregated to extract implant type, those describing treatment of pathologies other than depressed skull fractures, and non-English or cadaveric studies. The Newcastle-Ottawa Scale was utilized to assess for presence of bias in included studies. Results: Following final study selection, 18 articles were included for quantitative and qualitative analysis. Of the 177 patients (152 males), mean age was 30.8 years with 82% implanted with autologous graft material, and 18% with non-autologous material. Data were pooled and analyzed with respect to the total patient set, and additionally stratified into those treated through autologous and non-autologous implant material.There were no differences between the two cohorts regarding mean time to encounter, pre-operative Glasgow coma scale (GCS), fracture location, length to cranioplasty, and complication rate. There were statistically significant differences in post-operative GCS (p < 0.0001), LOS (p = 0.0274), and minimum follow-up time (p = 0.000796). Conclusion: Differences in measurable post-operative outcomes between implant groups were largely minimal or none. Future research should aim to probe these basic results deeper with a larger, non-biased sample.

Upper Transversal Hepatectomy with Two Hepatic Veins Reconstruction: Combining Parenchymal-Sparing Liver Surgery with Transplantation Techniques for Colorectal Liver Metastases.

BACKGROUND: Colorectal liver metastases (CRLM) involving two or three main hepatic veins pose a surgical challenge. For these lesions, compelled surgical strategies have usually included major and/or extended liver resections according to the two-stage hepatectomy (TSH) strategy. More recently, a one-stage transversal hepatectomy resecting the posterosuperior liver segment (7,8,4 superior) along with one or more hepatic veins has been described, such as showed herein in a didactical video. METHODS: The patient is a 78-year-old woman with two large CRLMs located into segment 2 and into segment 8. Magnetic resonance imaging and computed tomography showed tumour stability after chemotherapy. The lesion of segment 2 is close to the left hepatic vein while the lesion of segment 8 infiltrates the middle (MHV) and the right hepatic veins (RHV). RESULTS: Under intermittent pedicular clamping, resection of the segment 7, 8, 4 superior along with the right and middle hepatic veins is performed. Reconstruction of the veins was performed with 2 cryopreserved autologous saphenous grafts. Postoperative course was uneventful and postoperative CT scan showed patency of the two venous graft reconstructions. CONCLUSIONS: Surgery for CRLM has evolved over the last two decades shifting from large anatomical resections to parenchymal-sparing resections. Sparing liver parenchyma allows surgical radicality while reducing the risk of liver failure and allowing repeated liver resection. Associating vascular reconstruction to parenchymal-sparing surgery reduces the risk of venous congestion of the spared liver parenchyma.

Intraoperative extracorporeal irradiation for giant sarcoma-infiltrated calvarium: a case report.

Large bone defects that occur after resection of calvarial tumours are commonly remedied using titanium meshes or bone prostheses. However, these methods have several problems. While intraoperative extracorporeal radiotherapy for bone flaps could avoid these problems, there have been only a few reports wherein meningiomas were treated with 120 Gy irradiation. Moreover, no reports are available on calvarial metastasis of sarcoma, and the therapeutic radiation dose remains uncertain. Here, we report a case of giant calvarial metastasis of myxoid liposarcoma treated with intraoperative extracorporeal radiotherapy at a dose of 50 Gy. The treatment resulted in successful tumour control followed by favourable bone reconstruction.

In Situ Replacement for a Mycotic Aneurysm on the Porcelain Aorta Using the Superficial Femoral Artery as a Vascular Graft / 日本心臓血管外科学会雑誌

Infected thoracic aortic aneurysms are rare. Standard treatment methods have not yet been established for medical treatment, timing of surgery, or surgical techniques. In this study, we report a case in which an ascending aortic reconstruction using an autologous superficial femoral artery was successfully performed for an infected pseudoaneurysm of the thoracic aorta without the use of artificial materials. The patient was a 78-year-old man with bacteremia caused by Staphylococcus aureus and an infected pseudoaneurysm of the thoracic aorta. The patient underwent replacement of the ascending aorta and coronary artery bypass grafting. The patient was discharged from the hospital with no recurrence of infection and no abnormality of the reconstructed aorta.

[Reconstruction of painful neuroma of superficial branch of radial nerve after first dorsal compartment release: presentation of two cases]. / Reconstrucción de neuroma de nervio radial superficial con injerto autólogo de nervio sural: presentación de dos casos.

INTRODUCTION: nerve lesions are potentially catastrophic injuries. They can cause motor loss, severe pain and neuroma formation. The superficial branch of the radial nerve is at risk during first dorsal compartment release, its injury can cause neuroma formation. Autologous nerve reconstruction is the gold standard for treatment of small nerve gaps. CASES PRESENTATION: we present two cases of adult women (F/47 y F/51) with a prior history of first dorsal compartment release in another institution. Both patients developed debilitating neuropathic pain, as well as allodynia in the surgical site. They were diagnosed with superficial radial nerve neuroma. Oral medication and physical therapy was attempted without success. Surgical exploration and autologous nerve reconstruction was performed. Both patients had excellent relief of pain from visual analogue scale (VAS 9-10 to VAS 1-2). Postoperatively, both patients recovered partial sensitivity to pain in the zones distal to the repair. CONCLUSIONS: neuromas are feared complications that occur with unrecognized nerve lesions during surgery, they are difficult to treat and require multidisciplinary management. These two cases demonstrate that autologous nerve reconstruction is an excellent option for recovering function in small gaps of nerve tissue.

INTRODUCCIÓN: las lesiones iatrogénicas de nervio son complicaciones devastadoras de cualquier procedimiento quirúrgico. Ocasionan pérdida motora, dolor y formación de neuromas. En el abordaje para la liberación del primer compartimiento extensor de la muñeca, la rama superficial del nervio radial debe identificarse y protegerse previo a la liberación tendinosa. La lesión de este nervio sensitivo puede ocasionar dolor postoperatorio clínicamente significativo. La reconstrucción nerviosa con nervio autólogo ha demostrado en diversos escenarios buenos resultados para mejorar el dolor y recuperar la conducción nerviosa. PRESENTACIÓN DE LOS CASOS: se presentan dos casos de mujeres adultas (F/47 y F/51) con antecedente de liberación de primer compartimiento dorsal de muñeca en otro centro hospitalario. Desarrollaron posteriormente dolor incapacitante y alodinia en sitio quirúrgico, así como limitación funcional. Fueron evaluadas y diagnosticadas como neuroma de rama superficial del nervio radial. No hubo mejoría con terapia física, por lo que se realizó reconstrucción nerviosa con injerto autólogo de nervio sural. Ambas pacientes tuvieron alivio del dolor de EVA 9-10 hasta EVA 1-2. A los cuatro meses de seguimiento, las dos mujeres recuperaron parcialmente la sensibilidad distal al sitio del neuroma, sin recurrencia del dolor presentado. CONCLUSIONES: los neuromas son complicaciones devastadoras que ocurren con lesiones inadvertidas de nervios motores y sensitivos. La reconstrucción con nervio autólogo es una excelente opción para reconstrucción de pequeños tramos de nervio periférico.

Endonasal Septoplasty Using a Septal Cartilaginous Batten Graft for Managing Caudal Septal Deviation.

Caudal nasal septal deviation is an important condition altering nasal obstruction and cosmetic appearance and many surgical techniques have been published on how to correct caudal septal deviation, as successful management of caudal septal deviation is challenging. The goal of our study was to explore the effect of endonasal septoplasty using a septal cartilaginous batten graft for managing caudal septal deviation. We tested 26 participants with caudal septal deviation who received endonasal septoplasty using a septal cartilaginous batten graft from 1 April 2019 to 29 June 2022, and followed up for at least 6 months. Nasal Obstruction Symptom Evaluation (NOSE) Scale and visual analog scale (VAS) were recorded at baseline, 1 month, and 6 months after surgery. Valid samples were analyzed by repeated measures ANOVA and paired sample t-test. Average participant age was 36.15 ± 11.02 years old. The preoperative, 1-month postoperative, and 6-month postoperative NOSE scale decreased significantly (75.38 ± 15.62, 13.85 ± 7.79, and 14.04 ± 9.90; p < 0.001), while preoperative, 1-month postoperative, and 6-month postoperative VAS (convex/concave side) also improved (7.50 ± 0.81/3.38 ± 0.94, 2.27 ± 0.53/1.54 ± 0.58, and 2.31 ± 0.55/1.58 ± 0.58; p < 0.001). Our results showed that endonasal septoplasty using a septal cartilaginous batten graft had good surgical outcomes without an open scar or severe complications.

Phalangeal autologous bone graft for flail digit subluxation: A case report.

A 70-year-old patient was referred for a surgical opinion with a flail digit. Flail digit occurs as a result of over resection to the head of the proximal phalanx beyond the surgical neck and proximally into the shaft. The patient was complaining of a symptomatic right fourth digit (pain 7/10 on a Visual Analogue Scale) that had previously undergone two failed hammer toe surgeries resulting in symptomatic plantar hyperkeratosis with no history of ulceration or infection. The patient was surgically managed with autologous bone graft harvested from an adjacent digit biphalangic phalanx. Six months postoperative, the patient presented asymptomatic. Anatomical alignment, digital stabilisation and function were achieved. Full autologous graft consolidation was confirmed radiographically. Favourable patient-reported outcomes using the Manchester-Oxford Foot Questionnaire showed improvement in all domains. Currently, there is no published case study or description utilising our surgical technique to treat flail digit deformity.

Reverse Shoulder Arthroplasty with Bony and Metallic versus Standard Bony Reconstruction for Severe Glenoid Bone Loss. A Retrospective Comparative Cohort Study.

There are different techniques to address severe glenoid erosion during reverse shoulder arthroplasty (RSA). This study assessed the clinical and radiological outcomes of RSA with combined bony and metallic augment (BMA) glenoid reconstruction compared to bony augmentation (BA) alone. A review of patients who underwent RSA with severe glenoid bone loss requiring reconstruction from January 2017 to January 2019 was performed. Patients were divided into two groups: BMA versus BA alone. Clinical outcome measurements included two years postoperative ROM, Constant score, subjective shoulder value (SSV), and the American Shoulder and Elbow Surgeons Shoulder (ASES) score. Radiological outcomes included radiographic evidence of scapular complications and graft incorporation. The BMA group had significantly different glenoid morphology (p < 0.001) and greater bone loss thickness than the BA group (16.3 ± 3.8 mm vs. 12.0 ± 0.0 mm, p = 0.020). Both groups had significantly improved ROM (anterior forward flexion and external rotation) and clinical scores (Constant, SSV and ASES scores) at 2 years. Greater improvement was observed in the BMA group in terms of anterior forward flexion (86.3° ± 27.9° vs. 43.8° ± 25.6°, p = 0.013) and Constant score (56.6 ± 10.1 vs. 38.3 ± 16.7, p = 0.021). The BA group demonstrated greater functional and clinical improvements with higher postoperative active external rotation and ASES results (active external rotation, 49.4° ± 17.0° vs. 29.4° ± 14.7°, p = 0.017; ASES, 89.1 ± 11.3 vs. 76.8 ± 11.0, p = 0.045). The combination use of bone graft and metallic augments in severe glenoid bone loss during RSA is safe and effective and can be considered in cases of severe glenoid bone loss where bone graft alone may be insufficient.

Autologous lamellar keratoplasty for the treatment of feline corneal sequestrum: A retrospective study of 35 eyes (2012-2020).

OBJECTIVE: To evaluate the use of autologous lamellar keratoplasty for the treatment of feline corneal sequestrum (FCS). PROCEDURE: The medical records of cats diagnosed with FCS that underwent autologous lamellar keratoplasty between 2012 and 2020 with a minimum of 2 months of follow-up were reviewed. After keratectomy of FCS, a button adjacent to the corneal limbus was harvested on the same eye and sutured to the recipient bed. A nictitating membrane flap was left in place until the first recheck except for one patient. Postoperative treatment with topical and systemic antibiotics and systemic nonsteroidal anti-inflammatory medications was prescribed. Follow-up examinations were carried out 2 weeks, 1 month and 2 months post-operatively and consisted of a complete ophthalmic examination. RESULTS: A total of 35 cats (35 eyes) were included. The median follow-up time was 3.2 months (range, 2-59 months). Brachycephalic cats were overrepresented (85.7%). The mean graft size was 6.5 mm (range, 6-9 mm). Minor complications consisting of melting and partial integration of the graft occurred in 2/35 eyes (5.7%). Recurrence was observed in 1/35 eyes (2.9%) and was managed by a superficial keratectomy. A good visual outcome was achieved in all eyes, and a faint or mild corneal opacification occurred in 15/35 (42.9%). CONCLUSIONS: Autologous lamellar keratoplasty is an effective treatment for FCS, providing good tectonic support to the affected cornea and resulting in good visual and cosmetic outcomes. These results should be verified in future prospective studies that include a larger number of cases and longer-term follow-up.

The effectiveness of autologous demineralized tooth graft for the bone ridge preservation: a systematic review of the literature.

Resorption of alveolar ridge after tooth extraction often compromises dental implant placement and esthetic. Alveolar ridge preservation is a common procedure performed in order to preserve the pontic site for a prosthetically ideal position. This procedure has already become an indisputable need. Tooth matrix as bone substituted material poses osteoconduction and osteoinduction properties and as autologous graft, this material is free of antigenic reaction. This biomaterial allows the threedimensional reconstruction of the bone, is easy to prepare and has a low cost. The aim of this review is to summarize and put in evidence the properties of tooth as bone substitute and its use in alveolar ridge preservation. Keyword: autologous tooth, autologous graft, bone regeneration, bone substitute, alveolar ridge preservation, alveolar ridge augmentation, socket preservation.
