RESUMEN
CASE: A 32-year-old man presented with a type II open both-bone forearm fracture and segmental bone loss because of complete extrusion of a diaphyseal fragment (3 cm) of ulna. The patient presented to our level 1 trauma center after a motor vehicle collision. The extruded segment underwent sterilization and immediate reimplantation with internal fixation approximately 6 hours after arrival. Our patient achieved union by 7-month follow-up, demonstrated excellent functional outcomes, and was free from infection at 1-year follow-up. CONCLUSION: In select cases, successful reimplantation can be achieved by meticulous debridement, sterilization, and immediate reimplantation with internal fixation.

OBJECTIVES: Both aortic root remodelling and aortic valve (AV) reimplantation have been used for valve-sparing root replacement in patients with aortic root aneurysm with or without aortic regurgitation. There is no clear evidence to support one technique over the another. This study aimed to compare remodelling with basal ring annuloplasty versus reimplantation on a multicentre level with the use of propensity-score matching. METHODS: This was a retrospective international multicentre study of patients undergoing remodelling or reimplantation between 2010 and 2021. Twenty-three preoperative covariates (including root dimensions and valve characteristics) were used for propensity-score matching. Perioperative outcomes were analysed along with longer-term freedom from AV reoperation/reintervention and other major valve-related events. RESULTS: Throughout the study period, 297 patients underwent remodelling and 281 had reimplantation. Using propensity-score matching, 112 pairs were selected and further compared. We did not find a statistically significant difference in perioperative outcomes between the matched groups. Patients after remodelling had significantly higher reintervention risk than after reimplantation over the median follow-up of 6 years (P = 0.016). The remodelling technique (P = 0.02), need for decalcification (P = 0.03) and degree of immediate postoperative AV regurgitation (P < 0.001) were defined as independent risk factors for later AV reintervention. After exclusion of patients with worse than mild AV regurgitation immediately after repair, both techniques functioned comparably (P = 0.089). CONCLUSIONS: AV reimplantation was associated with better valve function in longer-term postoperatively than remodelling. If optimal immediate repair outcome was achieved, both techniques provided comparable AV function.

INTRODUCTION: Continuous extracorporeal perfusion (ECP), or machine perfusion, holds promise for prolonged skeletal muscle preservation in limb ischemia-reperfusion injury. This study aimed to extend the amputation-to-replantation time window from currently 6 hours to 33 hours using a 24-hour ECP approach. MATERIALS AND METHODS: Six large white pigs underwent surgical forelimb amputation under general anesthesia. After amputation, limbs were kept for 9 hours at room temperature and then perfused by 24-hour ECP with a modified histidine-tryptophan-ketoglutarate (HTK) solution. After ECP, limbs were orthotopically replanted and perfused in vivo for 12 hours. Clinical data, blood, and tissue samples were collected and analyzed. RESULTS: All 6 forelimbs could be successfully replanted and in vivo reperfused for 12 hours after 9 hours of room temperature ischemia followed by 24 hours ECP. Adequate limb perfusion was observed after replantation as shown by thermography and laser Doppler imaging. All pigs survived without severe organ failure, and no significant increase in inflammatory cytokines was found. Macroscopy and histology showed marked interstitial muscular edema of the limbs, whereas myofiber necrosis was not evident, implying the preservation of muscular integrity. CONCLUSIONS: The use of a 24-hour ECP has successfully extended limb preservation to 33 hours. The modified histidine-tryptophan-ketoglutarate perfusate demonstrated its ability for muscle protection. This innovative approach not only facilitates limb replantation after combat injuries, surmounting geographical barriers, but also broadens the prospects for well-matched limb allotransplants across countries and continents.

The primary goal is to preserve thumb integrity and functionality to the greatest extent possible, even in cases involving very small amputated parts. In this article, we present a case in whom the seemingly non-replantable dorsal skin-nail composite tissue of the thumb could be successfully replanted with a single artery anastomosis. No additional procedures were required, and complete recovery was achieved. In conclusion, given the unique vascular structure of the thumb, all amputated parts should be carefully evaluated for replantation. Replanting a partially amputated finger yields superior functional and cosmetic outcomes compared to any reconstructive method.

OBJECTIVES: The aim of this study was to present an institution's experience with cochlear reimplantation (CRI), to assess surgical challenges and post-operative outcomes and to increase the success rate of CRI. STUDY DESIGN: Retrospective single-institution study. SETTING: Tertiary medical center. METHODS: We retrospectively evaluated data from 76 reimplantation cases treated in a tertiary center between 2001 and 2022. Clinical features including etiology of hearing loss, type of failure, surgical issues, and auditory speech performance were analyzed. Categorical Auditory Performance (CAP) and Speech Intelligibility Rating (SIR) scores were used to evaluate pre- and post-CRI outcomes. RESULTS: The CRI population comprises of 7 patients from our institute,69 referred patients from other centers. Device failure was the most common reason (68/76, 89.5 %) for CRI; in addition, there were 7 medical failures and 1 had both soft device failure. Medical failures included flap rupture and device extrusion, magnet migration, auditory neuropathy, leukoencephalopathy, foreign-body residue and meningitis. In 21/76 patients, the electrode technology was upgraded. The mean time to failure was 0.58-13 years, with a mean of 4.97 years. The mean (± SD) CAP and SIR scores before and after CRI were 5.2 ± 1.2 versus 5.5 ± 1.1 and 3.4 ± 1.1 versus 3.5 ± 1.1, respectively. Performance was poor in six patients with severe cochlear malformation, auditory nerve dysplasia, leukoencephalopathy, and epilepsy. CONCLUSION: CRI surgery is a challenging but relatively safe procedure, and most reimplanted patients experience favorable postoperative outcomes. Medical complications and intracochlear damage are the main causes of poor postoperative results. Therefore, adequate preoperative preparation and atraumatic CRI should be carried out for optimal results.

ABSTRACT: The decision-making process for lower limb replantation involves several critical factors, such as age, comorbidities, ischemia time, type of injury, and psychosocial considerations. Advances in microsurgical techniques have led to a greater focus on enhancing functionality through limb salvage. To improve functional outcomes, it is essential to gain a better understanding of the current challenges in reconstruction and address them in future cases. Objective functional analysis of lower extremity replantation cases holds the potential to guide us in this endeavor. In this report, we present a lower limb replantation case with a 10-year follow-up, including objective functional evaluation with gait analysis.

Macro-amputations are extremely serious traumas and represent one of the rare extreme emergencies in hand and upper limb surgery. Their rarity, especially in our developed countries, makes their treatment relatively unknown by surgical and anesthetic teams. However, the action plan to use during a macro-reimplantation, the decisive elements of pre- and post-operative management, and the key stages of the surgery, must be perfectly known, because they determine the success of a major reimplantation, for the limb survival and the future functional result. After a brief historical overview, the literature review proposed here provides an opportunity for an update on these formidable injuries and propose a treatment algorithm to guide the medical team in the management of these complex patients.

BACKGROUND: Scalp replantation is the best treatment for scalp avulsion due to its functional and esthetic benefits. Regular scalp replantation requires only unilateral or bilateral superficial temporal vascular anastomosis. However, shear force always damages vessels in severe scalp avulsions. Short, superficial temporal vessels (STVs) make tension-free anastomosis challenging. PURPOSE: The objective of this article is to improve the regular scalp replantation technique. When the STVs are short, tension-free anastomosis, and cosmetic symmetry can be achieved without vein grafts or vascular replacement. METHOD: This study retrospectively reviewed 18 patients with scalp avulsion, of which 10 underwent scalp-shifting replantation, and 8 underwent regular scalp replantation with direct anastomosis of the STVs. Postoperatively, the authors, assessed whether there was a significant difference in the percentage of scalp survival and in the facial symmetry of patients between the 2 methods. RESULT: The percentages of scalp survival and facial symmetry were good after surgeries using both methods, and no significant differences were observed. CONCLUSION: The authors use scalp-shifting replantation to create tension-free anastomoses in cases where scalp avulsion injuries have left the superficial temporal arteries too short. This technique ensures facial symmetry, scalp reimplantation survival, and equally excellent results in function and esthetics.

BACKGROUND: This controlled experimental study aimed to compare ectopic replantation with other replantation techniques in a rat model of crush amputations. It also assessed the impact of different replantation methods on the viability of amputates. METHODS: Forty male Wistar albino rats were divided into four groups. Groin flaps served as the amputation model. Group 1 un-derwent guillotine-style amputation followed by orthotopic replantation, Group 2 experienced crush-type amputation and orthotopic replantation, Group 3 had crush-type amputation and orthotopic replantation with a vein graft, and Group 4 underwent crush-type amputation followed by ectopic replantation. Flap viability and perfusion rates were assessed on day 3 using an infrared perfusion as-sessment system. The ratio of viable area to total flap area and thrombus formation in the pedicle vessels were evaluated on day 7. RESULTS: Infrared evaluations on day 3 post-replantation revealed flap perfusion percentages of 73.5% in Group 1, 11.1% in Group 2, 65% in Group 3, and 64.1% in Group 4. Statistical analysis indicated that Group 1 exhibited the highest perfusion rates, while Group 2 showed the lowest. No differences were observed between Groups 3 and 4. On the seventh day, the average surviving flap areas were found to be 74.6% in Group 1, 2.5% in Group 2, 64.5% in Group 3, and 64% in Group 4. Statistically, Group 1 exhibited the best outcomes, while Group 2 had the poorest, with no differences between Groups 3 and 4. Additionally, thrombus formation was observed in the vessels of two animals in Group 1, nine in Group 2, and three each in Groups 3 and 4. Significant statistical differences were noted among the groups. CONCLUSION: The results indicate that ectopic replantation and replantation with a vein graft are equally effective. The preferred method for crush-type replantations may depend on the patient's and the amputated limb's conditions. In crush-type amputations, we recommend vein graft repair if the patient's overall condition supports replantation and if crushed segments can be debrided without excessive shortening of the amputated part. If these conditions are not met, temporary ectopic replantation is advised to preserve the amputated limb.

OBJECTIVES: Recently, patients with certain legacy cochlear implants (CIs) have sought out reimplantation to enjoy the benefits offered by newer processor technology. This decision can be difficult, especially when the individual relies exclusively on the device for communication and scores at the ceiling of performance metrics. To date, most outcome data is derived from reimplantation of a non-functioning CI-a relatively easy decision. The aim of this study is to report hearing outcomes following reimplantation of legacy implants to guide surgeons and patients approaching this high-stakes clinical situation. PATIENTS AND INTERVENTION: Four patients implanted with Advanced Bionics Clarion C1 devices over 20 years ago underwent reimplantation. RESULTS: Three reimplanted patients demonstrated a maintenance or improvement in their audiometric performance with one patient experiencing only a 5 % decrease in AzBioQ score. Each patient expressed satisfaction with the expansion of technological capabilities including improved battery life, and device connectivity. There were no failed reimplantations or other adverse effects. CONCLUSIONS: Reimplantation of a functioning legacy CI result in stability or improvement in auditory performance. All individuals in this series report that they enjoy the new connectivity and programming technologies. As the rate advancement in CI technology continues to increase and newer device architectures emerge, these data will help to inform the decision to reimplant functioning devices.

The number of amputated finger replantation has declined in the USA and Germany in recent years; however, there have been no reports on recent trends in Japan. We examined the current practices, attempts, and success factors of digit replantation in Japan. We hypothesized that the rates of digit replantation and success rates were consistently standardized in Japan. The diagnosis procedure combination database was used to analyze 14004 cases from April 2014 to March 2020, excluding multiple-digit amputations, thus focusing on 13484 patients. We evaluated replantation success rates and identified factors influencing replantation decisions using multiple logistic regression analysis. The key findings included a higher frequency of replantation in thumb cases and surgeries during overtime hours, on Sundays, and in educational institutions. Success rates were notably higher for thumb replantations and patients under 20 years of age. Patients over 65 years of age treated with urokinase showed higher failure rates, unrelated to regional or hospital case volumes. The number of amputated digit replantation surgeries in Japan was high during overtime hours, on Sundays, and in educational institutions. Region, hospital type, and hospital case volume were not associated with a low success rate across Japan.

In this article we would like to present, to our best knowledge, the very first published replantation of a forehead/part of a forehead as a single unit. The patient is a 57-year-old male smoker who sustained an avulsion forehead injury after a dog bite. Replantation was performed using microanastomosis of the supratrochlear vessels with restoration of good blood circulation after the procedure. Unfortunately, 5 days after the surgery, ischemia of the flap occurred followed by successful acute revision surgery. Nevertheless, the day after the ischemia reoccurred due to the time that passed, circumstances and unfavorable conditions affecting the sutured vessels, no further revision surgery was indicated. Observation continued and eventual wound necrosis after demarcation was left to be treated with skin grafting or per secundam intentionem. Only partial necrosis of the flap occurred, approximately 50%, which was subsequently treated with a full-thickness skin graft with very good results leading to the satisfaction of the patient.

INTRODUCTION: A common consideration for replantation success is the ischemia time following injury and the preservation temperature. A classic principle within the hand surgery community describes 12 hours of warm ischemia and 24 hours of cold ischemia as the upper limits for digit replantation; however, these limits are largely anecdotal and based on older studies. We aimed to compare survival data from the large body of literature to aid surgeons and all those involved in the replantation process in hopes of optimizing success rates. METHODS: The PubMed database was queried on April 4th, 2023, for articles that included data on digit replantation survival in terms of temperature of preservation and ischemia time. All primary outcomes were analyzed with the Mantel-Haenszel method within a random effects model. Secondary outcomes were pooled and analyzed using the chi-square statistic. Statistical analysis and forest plot generation were completed with RevMan 5.4 software with odds ratios calculated within a 95% confidence interval. RESULTS: Our meta-analysis identified that digits preserved in cold ischemia for over 12 hours had significantly higher odds of replantation success than the amputated digits replanted with 0-12 hours of warm ischemia time ( P ≤ 0.05). The odds of survival in the early (0-6 hours) replantation group were around 40% greater than the later (6-12 hours) replantation group ( P ≤ 0.05). Secondary outcomes that were associated with higher survival rates included a clean-cut amputation, increased venous and arterial anastomosis, a repair that did not require a vein graft, and replants performed in nonsmokers ( P ≤ 0.05). DISCUSSION: Overall, these findings suggest that when predicting digit replantation success, time is of the essence when the digit has yet to be preserved in a cold environment. This benefit, however, is almost completely diminished when the amputated digit is appropriately maintained in a cold environment soon after injury. In conclusion, our results suggest that there is potential for broadening the ischemia time limits for digit replant survival outlined in the literature, particularly for digits that have been stored correctly in cold ischemia.

PURPOSE: To compare the effects of a single-port-plus-one robotic laparoscopic-modified Lich-Gregoir direct nipple approach and traditional laparoscopic Cohen in treating pediatric primary obstructive megaureter. MATERIALS AND METHODS: The clinical data of 24 children with primary obstructive megaureter from January 2021 to November 2021 were analyzed retrospectively. Among them, 12 children (8 boys and 4 girls, the average age were 17.17 ± 6.31 months) treated with the laparoscopic Cohen method were defined as group C. The remaining 12 children (7 boys and 5 girls, the average age was 17.33 ± 6.99 months) underwent single-port-plus-one robotic laparoscopic-modified Lich-Gregoir direct nipple ureteral extravesical reimplantation were defined as group L. The parameters of pre-operation, intraoperative and postoperative were compared. RESULTS: There were no differences in the patient characteristics and average follow-up time between the two groups (P > 0.05).The obstruction resolution rate was 100% in both groups. The total operation time in group L is slightly longer than that in group C(P < 0.001),but the intraperitoneal operation time of the two groups was comparable(P > 0.05). The postoperative parameters included blood loss, gross haematuria time, indwelling catheterization time and hospitalization time in group L is shorter than group C(P < 0.05). One year post-operation, decreasing in ureteral diameter and APRPD, and increasing in DRF were remarkably observed in both two groups(P < 0.05). Ureteral diameter, APRPD, and DRF were not significantly different both in pre-operation and post-operation between Group L and Group C(P > 0.05). CONCLUSION: Single-port-plus-one robot-assisted laparoscopic-modified Lich-Gregoir direct nipple approach and traditional laparoscopic Cohen are both dependable techniques for ureteral reimplantation in the treatment of pediatric primary obstructive megaureter. Since Lich-Gregoir can preserve the physiological direction of the ureter and direct nipple reimplantation enhances the effect of anti-refluxing, this technique is favorable for being promoted and applied in robot surgery.

Soft tissue injuries to the midface (and nose) are common causes for seeking trauma care. As trauma patients, observing advanced trauma life support protocols is warranted given the risk of concomitant injuries. Here, options for optimizing tissue preservation, microvascular replantation, non-microvascular tissue replacement, and wound stabilization are discussed. Included in this discussion are data-driven predictors for successful replantation as well as technique descriptions with anatomic references to guide surgeons in choosing optimal donor vessels. In both partial and complete avulsion injuries, venous congestion is common. Several postoperative wound care protocols to maximize tissue perfusion and long-term viability are discussed.

PURPOSE: We describe long-term outcomes, including UTIs and need for reimplantation, after ureterovesicostomy (UV) as a lasting surgical procedure for children with primary obstructive megaureter (POM). MATERIALS AND METHODS: Children referred to our institution between 2016 and 2023 who underwent refluxing UV were analyzed. POM was defined as hydroureteronephrosis with distal ureteral dilatation > 7 mm and a negative workup for other etiologies of hydronephrosis. We assessed for surgical outcomes, complications, rate of UTI, and improvement in upper tract dilatation. Statistical analyses assessed for change in hydronephrosis metrics over follow-up. RESULTS: Among 183 patients diagnosed with POM, 47 (24%) underwent UV. Median age of presentation, surgery, and follow-up was 2, 9, and 43 months, respectively. A total of 7 patients developed 30-day complications: Clavien-Dindo grade 1 in 2 (transient urinary retention) and grade 2 in 5 (UTIs). During monitoring 14 (30%) developed UTIs and 7 (15%) required ureteral reimplant or UV takedown. After surgery there was a significant decrease in the proportion of patients with high-grade hydronephrosis, anteroposterior renal pelvis diameter, and maximum ureteral dilatation. CONCLUSIONS: Refluxing UV is a safe alternative to cutaneous diversion in POM. Most patients had improvement in upper tract dilatation with an acceptable short-term complication rate and need for reoperation (in comparison to routine later reimplantation). Our experience suggests that monitoring alone after UV is feasible, and that selective subsequent reconstruction is a reasonable strategy.

INTRODUCTION: The aim of this study is to assess the outcomes of parathyroid gland reimplantation with PR-FaST technique in patients undergoing thyroid surgery, focusing on graft functionality over a 5-year follow-up period. MATERIALS AND METHODS: We analyzed data from 131 patients who underwent parathyroid reimplantation using the PR-FaST technique during thyroid surgery due to inadvertent parathyroid removal or evident vascular damage. Postoperative evaluations included serum calcium (Ca), magnesium (Mg), and phosphorus (P) analyses on the 1st and 2nd postoperative days, at 10 days, and at 1, 3, 6 months, 1 year, and 5 years of follow-up. Additionally, the mean values of serum intact parathyroid hormone (iPTH) concentration were measured from blood samples collected from both the reimplanted arm (iPTH RA) and non-reimplanted arm (iPTH NRA) within the same period. RESULTS: Among 131 patients, at 10 days post-surgery, only 46 patients (35.1%) out of 131 exhibited graft viability (iPTH ratio >1.5). This percentage increased to 72.8% (94 patients) after 1 month and further to 87.8% (108 patients) after 3 months post-surgery. At 1 year, 84.7% of patients showed good graft functionality. After 5 years, the percentage remained stable, with graft viability observed in 81.3% of patients. Only 91 of the initial 131 patients completed follow-up up to 5 years, with a dropout rate of 30.5 %. CONCLUSIONS: Parathyroid reimplantation using the PR-FaST technique is a viable option for patients undergoing thyroidectomy and has been shown to be a reproducible and effective technique in most patients, with sustained graft functionality and parathyroid hormone production over a 5-year follow-up period.
