Integrating new approaches to care in a vascular wound clinic.

INTRODUCTION: An evidence-based approach is essential in the treatment of wounds to optimise healing, reduce costs and improve patient outcomes. AIM: This case study aimed to demonstrate our model of care, which assesses and manages patients with venous disease and complex wounds. In this case, venous leg ulcer (VLU) was treated with TLC-NOSF dressing and therapeutic compression. The wound was serially assessed using a smart App that gave the patient a graphic representation of their progress. DESIGN: Descriptive Observational Case Study. CLINICAL CARE: An evidence-based approach for managing a chronic, severe VLU. The patient was initially seen at the Outpatient Vascular Wound Clinic twice weekly, then every two weeks for conservative sharp wound debridement, skin care, dressing change, and compression therapy using a compression (Ready) wrap. Wound progress was monitored by the digital application 'Tissue Analytics', a "purposedesigned digital wound management platform that records, tracks, and analyses wounds". RESULTS: Week 1: On initial review, ulcer length was 3.15cm, width was 3.1 cm, and total surface area was 6.31 cm2. The wound base was mildly sloughy (<25%), with areas of good granulation tissue on view. Week 12: Length was 1.32 cm, width 1.50 cm, and total surface area of 1.45 cm2, a 77% reduction in wound size. Week 24: The length was 0.48 cm, the width was 0.64 cm, and the total surface area was 0.18 cm2. This represented a 97% reduction in wound size. Week 36: Length was 0.01 cm, the width 0.06 cm, with a total surface area of 0.00 cm2. This represented a 99.99% reduction in wound size. CONCLUSION: The patient's treatment for a complex venous leg ulcer included the application of TLC-NOSF dressing in combination with individualised therapeutic compression therapy. We found TLC-NOSF was very effective in combination with the best standard of VLU care (i.e. therapeutic graduated compression therapy). The clinician and patient were impressed with the healing rate at 12 weeks, as the wound dimensions were the lowest since the wound started six years ago. This dramatically improved patient concordance and engagement in care. Despite incomplete healing at 36 weeks, the wound-healing journey over the 36 weeks indicated wound closure was close. In addition, using a wound assessment App, the patient could immediately see the benefits of the new treatment, facilitating patient compliance with the treatment.

Exosome Therapy for a Nonhealing Scalp Wound Following Chemoradiation and Surgical Therapy.

This case report describes the safety and utility of a noninvasive therapy, Purified Exosome Product (PEP), for poorly healing scalp wounds in the setting of prior chemoradiation and surgery. A man in his 60s with a history of high-grade angiosarcoma of the right temporoparietal scalp reconstruction had a 1-year history of 2 nonhealing scalp wounds after neoadjuvant chemotherapy followed by concurrent chemoradiation therapy, wide local excision, and latissimus dorsi free flap and split-thickness skin graft. The patient underwent débridement followed by 4 collagen (Bellafill)-PEP and 4 fibrin (Tisseel)-PEP applications during 7 months in 2022. Photographs of the area of exposed bone of the temporoparietal wound were measured and standardized by ImageJ open-source software. The frontal wound was not routinely measured and therefore was qualitatively assessed by reviewing photographs over time. The frontal wound completely healed, and the temporoparietal wound showed a 96% decrease in overall size. The patient had no adverse effects of treatment and continues to demonstrate ongoing healing. This case exhibits the safety and utility of topical PEP therapy for noninvasive treatment of poorly healing scalp wounds and offers the potential for an alternative treatment of patients who are poor candidates for additional surgical intervention.

Clinical performance and safety of a debridement pad with abrasive and non-abrasive fibres.

BACKGROUND: Debridement is key to removing devitalised tissue, debris and biofilm as part of wound-bed preparation. Unlike many other methods of debridement, mechanical debridement with a pad is effective enough to be used independently without an adjunctive method of debridement, while being more accessible than other standalone options. OBJECTIVE: To explore the clinical performance and safety of a debridement pad with both abrasive and non-abrasive surfaces in daily clinical practice. METHODS: This was a prospective, non-controlled, non-randomised, single-arm, open-label, multicentred observational evaluation. Inclusion criteria were wounds >4 cm2 covered with at least 30% debris, necrotic tissue or slough in patients aged ≥18 years. The treatment protocol comprised a single application of the debridement pad. The primary outcome measure was the amount of necrotic tissue, slough or debris in the wound bed. Secondary outcomes included the appearance of the wound bed, edges and periwound skin; self-reported pain scores; foreseeable negative impacts; and clinician satisfaction. RESULTS: A total of 62 participants with a variety of wound types were included in the analysis. Most wounds (87%) had been present for over 3 months and had high or moderate exudate levels (90%). A significant reduction was observed in all three parameters: necrotic tissue (p=0.043), slough (p<0.001) and debris (p<0.001). Necrotic tissue, slough and debris showed mean relative reductions of 40%, 72% and 40%, respectively. Of participants, 84% did not experience an increase in pain during the debridement procedure. CONCLUSION: This clinical real-world data shows the debridement pad to be an effective and well-tolerated device for debridement and wound bed preparation.

Staged treatment with arterial reconstruction and flap transplantation for ischemic mangled extremity: An observational study.

Patients with traumatic ischemic mangled extremities first undergo arterial reconstruction using autogenous vein grafts, followed by flap transplantation as a staged treatment for soft tissue reconstruction. This study aimed to report the outcomes of such a staged treatment. Thirteen patients underwent arterial reconstruction between February 2015 and April 2017 due to damage to the major blood vessels by the traumatic mangled extremities. Of them, 6 patients (5 males and 1 female with a mean age of 51 years, age range: 36-60 years) who underwent soft tissue reconstruction due to necrosis were retrospectively analyzed. The average Mangled Extremity Severity Score was 7.2 (range, 6-8). Injuries were found in the lower leg (4 cases), foot (1 case), and wrist and hand (1 case). Arterial reconstruction was performed using autologous venous grafts. The reconstructed arteries included the posterior tibial artery (3 cases), anterior tibial artery (1 case), dorsalis pedis artery (1 case), and radial artery (1 case). The blood circulation status of the reconstructed blood vessels was assessed using computed tomography angiography at an average of 5 weeks (range, 4-6 weeks) after arterial reconstruction. For some necrotic soft tissues, debridement and flap transplantation were performed an average of 7 weeks (range, 6-8 weeks) after arterial reconstruction. Soft tissue reconstruction was performed with an anterolateral thigh free flap in 4 cases, a local flap in 1 case, and a muscle flap in 1 case. In 5 out of 6 cases, blood circulation was maintained in the reconstructed blood vessels, resulting in the salvaging of the extremities. All the patients who underwent flap surgery survived. Notably, there were no special complications during a follow-up visit conducted at an average of 19 months post-reconstruction. To treat an ischemic mangled extremity, the limbs should first be salvaged with arterial reconstruction, followed by subsequent appropriate flap surgery when soft tissue necrosis occurs at the mangled site as a staged treatment.

Efficacy and safety of ultrasound-assisted wound debridement in the treatment of diabetic foot ulcers: a systematic review and meta-analysis of 11 randomized controlled trials.

Objective: Research data suggests that ultrasound-assisted wound debridement (UAWD) can effectively promote the healing of diabetic foot ulcers (DFU). However, existing research is not consistent with this viewpoint. Therefore, we conducted this study to investigate the effect of UAWD on the healing of diabetic foot ulcers. Methods: From the establishment of the database to January 2024, we searched 8 databases to study the effectiveness and safety of UAWD in the treatment of DFU. Two authors independently screened the qualifications of the articles, while two authors extracted relevant data. Statistical analysis was conducted using Review Manager 5.4 and STATA 18.0 software. Results: A total of 11 randomized controlled studies were included, with 6 countries and 696 participants participating. Our findings showed that UAWD was associated with a significant benefit in healing rate (OR = 2.60, 95% CI: [1.67, 4.03], P < 0.0001, I2 = 25%), wound healing time (MD = -11.94, 95% CI: [-23.65, -0.23], P = 0.05, I2 = 99%), percentage reduction in wound size (MD = 14.2, 95% CI: [10.8, 17.6], P = 0.47, I2 = 32%), effectiveness of treatment (OR = 10.3, 95% CI: [4.68, 22.66], P < 0.00001, I2 = 0%). Moreover, UAWD did not cause any significant adverse reactions. However, there was no obvious difference in wound blood perfusion (MD = 0.25, 95% CI: [-0.01, 0.52], P = 0.06, I2 = 90%), transcutaneous oxygen partial pressure (MD = 14.34, 95% CI: [-10.03, 38.71], P = 0.25, I2 = 98%). Conclusion: UAWD can significantly improve wound healing rate, shorten wound healing time, accelerate wound area reduction, and improve clinical treatment effectiveness without significant adverse reactions. Although there is no significant difference in transcutaneous oxygen pressure and wound blood flow perfusion between UAWD and SWC. So we look forward to more scientifically blinded, placebo-controlled, high-quality studies in the future, to enable researchers to obtain more complete and accurate analytical data, in order to improve the scientific and credibility of the evidence.

Topical desiccating agent (DEBRICHEM): an accessible debridement option for removing biofilm in hard-to-heal wounds.

It is now assumed that all hard-to-heal wounds contain biofilm. Debridement plays a key role in wound-bed preparation, as it can remove biofilm along with the devitalised tissue, potentially leaving a clean wound bed that is more likely to progress towards healing. The gold standard methods of debridement (surgical and sharp) are the least used, as they require specialist training and are often not readily available at the point of need. Most other methods can be used by generalists but are slower. They all need regular applications. The topical desiccating agent DEBRICHEM is an innovative alternative, as it is fast, effective and can be used in all clinical settings, as well as typically requiring only a single use. This article describes best practice for achieving optimal outcomes with its use.

Efficacy and safety of an anti-infection topical desiccating agent (DEBRICHEM) in hard-to-heal wounds.

A single centre, non-comparative evaluation was undertaken to observe the clinical results achieved when following best practice for the application of Debrichem. The treatment protocol involved use of this debridement product plus standard of care. The sample comprised 21 patients with complex, non-healing wounds of various aetiologies. One patient dropped out of the evaluation for unknown reasons. Wound types were either venous leg ulcers (n=16) or post-traumatic wounds (n=25). The mean wound duration was 22 months (range: 2 weeks-17 years). Over the 4-week follow-up period, there was a decline in the mean percentage of devitalised tissue present on the wounds, reducing from 69% at baseline to 49% at week 4. Most of the devitalised tissue was slough, for which the mean baseline percentage was 63% compared with an endpoint of 49%. Conversely, the mean percentage of granulation tissue increased from 31% at baseline to 51% at week 4. The mean visual analogue pain score reported during application was 4/10, where 0 represents no pain. However, general wound-related pain scores improved during the follow-up period, with no scores above 2 at week 2, compared with five at baseline. The results indicate that Debrichem is a safe and effective method of debridement that requires minimal training and is single use.

Limited debridement combined with ReCell® Techniques for deep second-degree burns.

BACKGROUND: The purpose of this article is to introduce a method that combines limited debridement and ReCell® autologous cell regeneration techniques for the treatment of deep second-degree burn wounds. METHOD: A total of 20 patients suffered with deep second-degree burns less than 10% of total body surface area (TBSA) who were admitted to our department, from June 2019 to June 2021, participated in this study. These patients first underwent limited debridement with an electric/pneumatic dermatome, followed by the ReCell® technique for secondary wounds. Routine treatment was applied to prevent scarring after the wound healed. Clinical outcomes were scored using the Vancouver Scar Scale (VSS). RESULTS: All wounds of the patients healed completely. One patient developed an infection in the skin graft area and finally recovered by routine dressing changes. The average healing time was 12 days (range: 10-15 days). The new skin in the treated area was soft and matched the colour of the surrounding normal skin and the VSS score ranged from 3~5 for each patient. Of the 20 patients, 19 were very satisfied and 1 was satisfied. CONCLUSIONS: This article reports a useful treatment method that combines electric dermatome-dependent limited debridement and the ReCell® technique for the treatment of deep second-degree burn wounds. It is a feasible and effective strategy that is easy to implement and minimally invasive, and it is associated with a short healing time, mild scar formation and little damage to the donor skin area.

Central toxic keratopathy leading to epithelial ingrowth following femtosecond LASIK.

We report a case of a woman in her 30s who underwent femtosecond LASIK (laser-assisted in situ keratomileusis) in both eyes to correct her simple myopic astigmatism. After the surgery, both eyes developed diffuse lamellar keratitis, and intensive topical steroids were initiated to control the same. Subsequently, central toxic keratopathy (CTK) developed bilaterally. Three weeks after the surgery, the right eye showed signs of progressive epithelial ingrowth involving the pupillary area. Surgical intervention in the form of flap relift followed by debridement of the epithelial cells and an alcohol interface wash were performed to treat the same. This is the first report of an epithelial ingrowth following CTK after femtosecond LASIK.

Osseoscopy-assisted core decompression and debridement in the treatment of avascular necrosis of the femoral head.

Core decompression of the femoral head is a standard surgical procedure used in the early stages of the femoral head avascular necrosis (AVN) (Steinberg I to III). This study aimed to determine whether the advantages of osseoscopy-assisted core decompression using a standard arthroscopic set up in the early stages of AVN of the femoral head. Twelve hips of 12 patients who underwent osseoscopy-assisted core decompression and debridement with the diagnosis of AVN of the femoral head were reviewed between 2019 and 2021. The etiology was idiopathic in 2 patients; ten had a history of steroid use. The preoperative and postoperative first month Harris Hip Score (HHS) and visual analogue scale (VAS) were recorded. Standard X-rays, computerized tomography, and magnetic resonance imaging (MRI) were noted at preoperatively and sixth month follow-ups. In a 1-year follow-up, X-rays and MRIs were reviewed. All patients significantly improved in the VAS and HHS after the osseoscopy-assisted core decompression (P = .002). Two of the 12 patients with an initial stage of Steinberg IIC and IIB and one with Steinberg IA had a progressive femoral collapse and, therefore, had a total hip replacement at the end of the follow-up. Nine patients (75%) had satisfactory functional and radiological results in 1-year of follow-up. However, 3 patients (25%) culminated in total hip arthroplasty in a 1-year follow-up. Using an arthroscopic set up during osseoscopy-assisted core decompression surgery of the femoral head AVN has the benefits of direct visualization and accurate debridement of the involved area. The osseoscopy-assisted core decompression technique avoids excessive debridement of the healthy bone tissue adjacent to the necrotic area.

Healing of Periodontal Suprabony Defects following Treatment with Open Flap Debridement with or without Hyaluronic Acid (HA) Application.

Background and Objectives: This randomized, double-arm, multicentric clinical trial aims to compare the clinical outcomes following the treatment of suprabony periodontal defects using open flap debridement (OFD) with or without the application of hyaluronic acid (HA). Materials and Methods: Sixty systemically healthy patients with at least two teeth presenting suprabony periodontal defects were randomly assigned with a 1:1 allocation ratio using computer-generated tables into a test (OFD + HA) or control group (OFD). The main outcome variable was clinical attachment level (CAL). The secondary outcome variables were changes in mean probing pocket depth (PPD), gingival recession (GR), full-mouth plaque score (FMPS), and full-mouth bleeding score (FMBS). All clinical measurements were carried out at baseline and 12 months. Results: Sixty patients, thirty in each group, were available for statistical analysis. The mean CAL gain was statistically significantly different (p < 0.001) in the test group compared with the control group (3.06 ± 1.13 mm vs. 1.44 ± 1.07 mm). PPD reduction of test group measurements (3.28 ± 1.14 mm) versus the control group measurements (2.61 ± 1.22 mm) were statistically significant (p = 0.032). GR changes were statistically significant only in the test group 0.74 ± 1.03 mm (p < 0.001). FMBS and FMPS revealed a statistically significant improvement mostly in the test group. Conclusions: Suprabony periodontal defects could benefit from the additional application of HA in conjunction with OFD in terms of improvement of the clinical parameters compared with OFD alone.

Decision-making on peri-implant mucositis management and treatment approaches.

Peri-implant mucositis is characterised by inflammation of soft tissues surrounding a dental implant without associated bone loss beyond initial remodelling. Early detection and timely intervention are critical to prevent its progression to peri-implantitis. This paper focuses on various treatment options for treating peri-implant mucositis. The cornerstone of professional treatment lies in the mechanical disruption and removal of microbial biofilms around the implant. This can be achieved through careful use of manual or powered instruments, such as ultrasonic scalers or air polishing devices. However, there is a need for further research to determine the most effective single approach for treating peri-implant mucositis. Current evidence does not support the combination of mechanical debridement with locally administered antibiotics. Contrarily, evidence strongly supports the removal, cleaning, and modifications of prostheses to improve both self-performance and professional cleanability. The use of adjunctive therapies like photodynamic therapy and diode laser, in conjunction with mechanical instrumentation, is not currently recommended due to the limited strength of available evidence. Preventive measures emphasise the importance of comprehensive oral hygiene care, encompassing professional guidance and at-home practices, to manage biofilms effectively. This encompasses oral hygiene instruction, regular debridement, and maintenance care. Supporting peri-implant therapy is also vital for ongoing implant monitoring, preventing the recurrence of mucositis, and halting its progression to peri-implantitis. This multifaceted approach is key to effectively managing and treating peri-implant mucositis.

Application of personalized templates in minimally invasive management of coronal dens invaginatus: a report of two cases.

BACKGROUND: Treating the coronal dens invaginatus (CDI) with pulp infection commonly involves the removal of invagination, which increases the risk of perforation and fracture, and compromises the tooth structure. Minimally invasive endodontic management of CDI is highly recommended. This report describes two cases of type II CDI with the application of personalized templates. CASE PRESENTATION: Two cases of type II CDI, affecting the main root canal in a maxillary canine and a lateral incisor, were diagnosed. A guided endodontics (GE) approach was applied. Cone-beam computed tomography and intraoral scans were imported and aligned in a virtual planning software to design debridement routes and templates. The MICRO principle (which involves the aspects of Mechanical (M) debridement, Irrigation (I), Access cavities (C), Rectilinear routes (R), and Obstruction (O)) was proposed for designing optimal debridement routes for future applications. The templates were innovatively personalized and designed to preserve the tooth structure maximally while effectively debriding the root canal. Root canal treatment with supplementary disinfection was then performed. The follow-up of the two patients revealed favorable clinical and radiographic outcomes. CONCLUSIONS: The GE approach could be a feasible method for preserving healthy dental structure while effectively debriding the root canal, thereby achieving successful and minimally invasive endodontic treatment for CDI.

Debridement for surgical wounds.

BACKGROUND: Surgical wounds that become infected are often debrided because clinicians believe that removal of this necrotic or infected tissue may expedite wound healing. There are numerous methods of debridement available, but no consensus on which one is most effective for surgical wounds. OBJECTIVES: To assess the effects of different methods of debridement on the rate of debridement and healing of surgical wounds. SEARCH METHODS: In October 2021, we searched the Cochrane Wounds Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL. To identify additional studies, we searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies, reviews, meta-analyses, and health technology reports. There were no restrictions on language, date of publication, or study setting. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that enrolled people with a surgical wound that required debridement, and reported time to complete wound debridement or time to wound healing, or both. DATA COLLECTION AND ANALYSIS: Two review authors independently performed study selection, risk of bias assessment using the RoB 1 tool, data extraction, and GRADE assessment of the certainty of evidence. MAIN RESULTS: In this fourth update, we identified one additional study for inclusion. The review now includes six studies, with 265 participants, aged three to 91 years. Five studies were published between 1979 and 1990 and one published in 2014. The studies were carried out in hospital settings in China, Denmark, Belgium, and the UK. Six studies provided six comparisons. Due to the heterogeneity of studies, it was not appropriate to conduct meta-analyses. Four studies evaluated the effectiveness of dextranomer beads/paste; however, each study used a different comparator (Eusol-soaked dressings, 10% aqueous polyvinylpyrrolidone, 0.1% chloramine-soaked packs, and silicone foam elastomer dressing). One study compared streptokinase/streptodornase with saline-soaked dressings, and one compared endoscopic surgical debridement with conventional 'open' surgical debridement. Five studies reported time to complete debridement (reported as time to a clean wound bed) and three reported time to complete healing. One study reported effect estimates (surgical debridement via endoscopy versus surgical debridement) for time to a clean wound bed and time to complete wound healing, and it was possible to calculate effect estimates for one other study (dextranomer paste versus silicone foam elastomer) for time to complete wound healing. For the other four studies that did not report effect estimates, it was not possible to calculate time to a clean wound bed or time to complete wound healing due to missing variance and participant exclusions. None of the included studies reported outcomes pertaining to proportion of wounds completely healed, rate of reduction in wound size, rate of infection, or quality of life. All studies had unclear or high risk of bias for at least one key domain. Dextranomer paste/beads (autolytic debridement) compared with four different comparators Four studies compared dextranomer paste or beads with Eusol-soaked gauze (20 participants), 10% aqueous polyvinylpyrrolidone (40 participants), 0.1% chloramine-soaked dressings (28 participants), or silicone foam elastomer (50 participants). There is very low-certainty evidence that there may be no clear difference in time to a clean wound bed between dextranomer beads and Eusol gauze. The study did not report adverse events. There is very low-certainty evidence that there may be no difference in time to a clean wound bed between dextranomer paste and 10% aqueous polyvinylpyrrolidone gauze. There was low-certainty evidence that there may be no difference in deaths and serious adverse events. There may be a difference in time until the wounds were clinically clean and time to complete wound healing between dextranomer paste and 0.1% chloramine favouring 0.1% chloramine, but we are very uncertain. There is low-certainty evidence that there may be no difference in deaths and serious adverse events. There is very low-certainty evidence that there may be no difference in time to complete healing between dextranomer beads and silicone foam elastomer. The study did not report adverse events. Streptokinase/streptodornase solution (enzymatic) compared with saline-soaked dressings One study (21 participants) compared enzymatic debridement with saline-soaked dressings. There is low-certainty evidence that there may be no difference in time to a clean wound bed or secondary suture between streptokinase/streptodornase and saline-soaked dressings. There is very low-certainty evidence that there may be no difference in deaths and serious adverse events. Surgical debridement via endoscopic ('keyhole') surgery compared with surgical debridement by 'open' surgery (the wound is opened using a scalpel) One study (106 participants) reported time to complete wound healing and time to a clean wound bed. There is low-certainty evidence that there may be a reduction in time to complete wound healing and very low-certainty evidence that there may be no difference in time to a clean wound bed with surgical debridement via endoscopy compared to 'open' surgical debridement. The study did not report adverse events. Overall, the evidence was low to very low-certainty for all outcomes. Five included studies were published before 1991 and investigated treatments that are no longer available. Worldwide production of dextranomer products has been discontinued, except for dextranomer paste, which is currently only available in South Africa. Furthermore, Eusol, used in one study as the comparator to dextranomer, is rarely used due to risk of harmful effects on healthy tissue and the enzymatic agent streptokinase/streptodornase is no longer available worldwide. AUTHORS' CONCLUSIONS: Evidence for the effects of different methods of debridement on complete wound debridement and healing of surgical wounds remains unclear. Adequately powered, methodologically robust RCTs evaluating contemporary debridement interventions for surgical wounds are needed to guide clinical decision-making.

Limb salvage and systemic management of gouty tophi: Case series.

INTRODUCTION: Gout is a chronic disease characterized by deposition of monosodium urate crystals. Tophi develop in some individuals with untreated or uncontrolled gout, which leads to ulcerations, cosmetic problems, mechanical obstruction of joint movement, joint damage and musculoskeletal disability. Currently, the treatment of gouty tophi is controversial and challenging. Both surgical and internal medical treatments have limitations and require further exploration in clinical practice. PATIENT CONCERNS: In Case 1, we treated a patient with severe infection of diabetic foot ulcers with concomitant multiple gouty tophi in the same limb. A systematic management strategy was formulated to close the wound and save the limb. The ulcers healed successfully after half a year. In Case 2, a giant gouty tophi located in the first metatarsophalangeal joint of the left foot was removed by surgical treatment and vancomycin-loaded bone cement implantation. In Case 3, we present a case of gouty tophi that was resolved by standardized systemic medical management. DIAGNOSIS: Three patients were all diagnosed with gout accompanied by gouty deposition, although there were other different comorbidities. INTERVENTIONS: In case 1, we used debridement to gradually remove gouty tophi. In case 2, the giant gouty tophi was removed by surgical operation. In case 3, the gouty tophi disappeared after standardized treatment with medicine, diet and lifestyle management. OUTCOMES: Three patients underwent different treatment therapies to remove gouty tophi based on their specific conditions. LESSONS: We explored effective interventions for tophi in gout by surgical or other interventions in combination with pharmacotherapy.

Trifocal versus Pentafocal bone transport in segmental tibial defects: a matched comparative analysis for posttraumatic osteomyelitis treatment.

PURPOSE: The objective of this study was to evaluate and compare the effectiveness and clinical results of trifocal bone transport (TBT) and pentafocal bone transport (PBT) in treating distal tibial defects > 6 cm resulting from posttraumatic osteomyelitis, highlighting the potential advantages and challenges of each method. METHODS: A retrospective assessment was conducted on an overall population of 46 eligible patients with distal tibial defects > 6 cm who received treatment between January 2015 and January 2019. Propensity score analysis was used to pair 10 patients who received TBT with 10 patients who received PBT. The outcomes assessed included demographic information, external fixation time (EFT), external fixation index (EFI), bone and functional outcomes assessed using the Association for the Study and Application of the Method of Ilizarov (ASAMI) scoring system, and postoperative complications evaluated using the Paley classification. RESULTS: The demographic and baseline data of the two groups were comparable. Following radical debridement, the average tibial defect was 7.02 ± 0.68 cm. The mean EFT was significantly shorter in the PBT group (130.9 ± 16.0 days) compared to the TBT group (297.3 ± 14.3 days). Similarly, the EFI was lower in the PBT group (20.67 ± 2.75 days/cm) than in the TBT group (35.86 ± 3.69 days/cm). Both groups exhibited satisfactory postoperative bone and functional results. Pin site infection was the most common complication and the rates were significantly different between the groups, with the PBT group demonstrating a higher incidence. CONCLUSION: Both TBT and PBT effectively treat posttraumatic tibial defects greater than 6 cm, with PBT offering more efficient bone regeneration. However, PBT is associated with a higher rate of pin site infections, highlighting the importance of careful management in these complex procedures and emphasizing the need for expert surgical execution and tailored treatment approaches in orthopedic reconstructive surgery.

Arthroscopic debridement and microfracture for bilateral osteochondral lesions on the lateral process of the talus involving the subtalar joint: A case report.

RATIONALE: Osteochondral lesions on the lateral process of the talus involving the subtalar joint are rare; the optimal surgical treatment remains to be clarified as there are few reports. Additionally, bilateral cases are extremely rare. Therefore, the clinical outcomes of the surgical treatment for bilateral osteochondral lesions on the lateral process of the talus involving the subtalar joint have not been fully elucidated. PATIENT CONCERNS: A 16-year-old boy who played soccer presented to our hospital with bilateral hindfoot pain. The symptoms persisted even after 3 months of conservative treatment. The patient and family requested surgical treatment to relieve the symptoms. DIAGNOSES: The patient was diagnosed with bilateral osteochondral lesions on the lateral process of the talus, involving the subtalar joint based on computed tomography and magnetic resonance imaging findings. INTERVENTIONS: Arthroscopic debridement and microfracture were performed bilaterally. OUTCOMES: Postoperative computed tomography and magnetic resonance imaging of both feet revealed remodeling of the subchondral bone. The patient returned to play at the pre-injury level with no pain. LESSONS: This report describes a case of bilateral osteochondral lesions on the lateral process of the talus, involving the subtalar joint. Arthroscopic debridement and microfracture were effective in relieving symptoms and the subchondral bone remodeling. To the best of our knowledge, this is the first report of arthroscopic treatment of osteochondral lesions of the lateral process of the talus involving the subtalar joint.

Surgical treatment of peri-implantitis.

As utilisation of dental implants continues to rise, so does the incidence of biological complications. When peri-implantitis has already caused extensive bone resorption, the dentist faces the dilemma of which therapy is the most appropriate to maintain the implant. Since non-surgical approaches of peri-implantitis have shown limited effectiveness, the present paper describes different surgical treatment modalities, underlining their indications and limitations. The primary goal in the management of peri-implantitis is to decontaminate the surface of the infected implant and to eliminate deep peri-implant pockets. For this purpose, access flap debridement, with or without resective procedures, has shown to be effective in a large number of cases. These surgical treatments, however, may be linked to post-operative recession of the mucosal margin. In addition to disease resolution, reconstructive approaches also seek to regenerate the bone defect and to achieve re-osseointegration.

Subacromial Surgery for Irreparable Posterosuperior Rotator Cuff Tears.

The irreparable posterosuperior rotator cuff tear describes a tear of the supraspinatus and/or infraspinatus tendon that is massive, contracted, and immobile in both the anterior-posterior and medial-lateral directions. Patients with an intact subscapularis and preserved forward elevation are challenging to treat because there is not a consensus treatment algorithm. For low-demand, elderly patients, several subacromial surgical options are available that can provide pain relief without the risks or burden of rehabilitation posed by reverse total shoulder arthroplasty or a complex soft-tissue reconstruction (e.g., superior capsular reconstruction, tendon transfer, bridging grafts). Debridement, more specifically the "smooth-and-move" procedure, offers a reliable outcome with documented improvements in pain and function at long-term follow-up. Similarly, the biodegradable subacromial balloon spacer (InSpace; Stryker, Kalamazoo, MI) has been shown to significantly improve pain and function in patients who are not responsive to nonoperative treatment. Disease progression with these options is possible, with a small percentage of patients progressing to rotator cuff arthropathy. Biologic tuberoplasty and bursal acromial reconstruction are conceptually similar to the balloon spacer but instead use biologic grafts to prevent bone-to-bone contact between the humeral head and the acromion. Although there is no single gold standard treatment, the variety of surgical techniques allows patients and surgeons to effectively manage these challenging situations.
