RESUMO

BACKGROUND: Chronic osteomyelitis is an invalidating disease, and its severity grows according to the infection's particular features. The Cierny-Maiden criteria classify it according to the anatomical aspects (I to IV) and also by physiological class (A host being in good immune condition and B hosts being locally (L) or systemically (S) compromised). The surgical approach to chronic osteomyelitis involves radical debridement and dead space reconstruction. Two-stage management with delayed reconstruction is the most common surgical management, while one-stage treatment with concomitant reconstruction is a more aggressive approach with less available literature. Which method gives the best results is unclear. The purpose of this study is to compare single and two-stage techniques. METHODS: The authors carried out a retrospective multicentric cohort study to compare two primary outcomes (bone union and infection healing) in one versus two-stage reconstructions with vascularized bone flaps in 23 cases of limb osteomyelitis (22 patients, 23 extremities). Thirteen subjects (56.5%) sustained a single-stage treatment consisting of a single surgery of radical debridement, concomitant soft tissue coverage, and bone reconstruction. Ten cases (43.5%) sustained a two-stage approach: radical debridement, simultaneous primary soft tissue closure, and antibiotic PMMA spacers implanted in 7 patients. RESULTS: No statistical differences were observed between one- and two-stage approaches in bone union rate and infection recurrence risk. Even though bone union seems to be higher and faster in the two-stage than in the one-stage group, and all infection relapses occurred in the one-stage group, data did not statistically confirm these differences. Two of the six cases (33.3%) of bone nonunion occurred in compromised hosts (representing only 17.4% of our sample). The B-hosts bone union rate was 50.0%, while it reached 78.9% in A-hosts, but the difference was not statistically significant (p = .5392). Infection recurrence was higher in B-hosts than in A-hosts (p = .0086) and in Pseudomonas aeruginosa sustained infections (p = .0208), but in the latter case, the treatment strategy did not influence the outcome (p = .4000). CONCLUSIONS: Bone union and infection healing rates are comparable between one and two-stage approaches. Pseudomonas aeruginosa infections have a higher risk of infection relapse, with similar effectiveness of one- and two-stage strategies. B-hosts have a higher infection recurrence rate without comparable data between the two approaches. Further studies with a larger sample size are required to confirm our results and define B-hosts' best strategy. LEVEL OF EVIDENCE: Level III of evidence, retrospective cohort study investigating the results of treatments.

RESUMO

BACKGROUND: Free vascularized fibula flap represents the gold standard vascularized bone graft for the management of segmental long bone defects after traumatic injury. The current study represents the largest retrospective multicenter data collection on the use of free fibula flap (FFF) for extremities' orthoplastic reconstruction after trauma aiming to highlight current surgical practice and to set the basis for updating current surgical indications. METHODS: The study is designed as a retrospective analysis of prospectively collected data between 2009 and 2021 from six European University hospitals. Patients who underwent fibula flap reconstruction after acute traumatic injury (AF) or as a late reconstruction (LF) after post-traumatic non-union of upper or lower limb were included. Only extra-articular, diaphyseal fracture were included in the study. Surgical data were collected. Time to bone healing and complications were reported as clinical outcomes. RESULTS: Sixty-two patients were included in the study (27 in the AF group and 35 in the LF group). The average patients' age at the time of the traumatic event was 45.3 ± 2.9 years in the AF group and 41.1 ± 2.1 years in the LF group. Mean bone defect size was 7.7 ± 0.6 cm for upper limb and 11.2 ± 1.1 cm (p = .32) for lower limb. Bone healing was uneventful in 69% of treated patients, reaching 92% after complementary procedures. Bone healing time was 7.6 ± 1.2 months in the acute group and 9.6 ± 1.5 months in the late group. An overall complication rate of 30.6% was observed, with a higher percentage of late bone complications in the LF group (34%), mostly non-union cases. CONCLUSIONS: FFF reconstruction represents a reliable and definitive solution for long bone defects with bone healing reached in 92% cases with a 8.4 months of average bone healing time.

RESUMO

BACKGROUND: The rate of fracture nonunion varies depending on the anatomical site. Numerous procedures have been proposed to treat recalcitrant nonunions. The vascularized medial femoral condyle corticoperiosteal free flap (MFCCFF) is increasingly used in nonunions with small bone loss.The percentage of success of the MFCCFF is high but the factors involved in delayed bone healing or failure of this technique or the contraindications are not described in the literature.This multicentric study aims to identify and report the different factors involved in determining the time of bone healing in the treatment of atrophic nonunion of long bones with the vascularized medial MFCCFF. METHODS: All patients who underwent vascularized medial MFCCFF from January 2011 to December 2020 for the treatment of recalcitrant atrophic nonunions of long bones. Patients were reviewed at 2 and 6 weeks, and 3, 6, and 12 months postoperatively and evaluated by physical and radiographic examinations and patient-reported outcome measures. RESULTS: The final study population comprised 59 patients with a mean follow-up of 26.2 ± 7.6 months, a rate of bone healing of 94.9% with a mean radiographic bone healing time of 4.1 ± 1.3 months, and low morbidity of the donor site. Diabetes mellitus, a body mass index (BMI) ≥30 kg/m2, and ≥2 previous surgeries on the fracture site were factors predicting timing for bone healing at the multivariate analysis. CONCLUSION: This study demonstrates the MFCCFF as an effective and safe procedure for the treatment of the recalcitrant atrophic nonunion of long bones. An association was found between the lengthening of bone healing time and a high BMI, presence of ≥2 previous surgical interventions, and diabetes mellitus, indicating these comorbidities as risk factors (not absolute contraindications) for this microsurgical treatment. So, to our knowledge, the MFCCFF could be the first-choice treatment for atrophic nonunion of long bones.

RESUMO

BACKGROUND: Peripheral nerve injuries (PNIs) include several conditions in which one or more peripheral nerves are damaged. Trauma is one of the most common causes of PNIs and young people are particularly affected. They have a significant impact on patients' quality of life and on the healthcare system, while timing and type of surgical treatment are of the utmost importance to guarantee the most favorable functional recovery. To date, several different classifications of PNIs have been proposed, most of them focusing on just one or few aspects of these complex conditions, such as type of injury, anatomic situation, or prognostic factors. Current classifications do not enable us to have a complete view of this pathology, which includes diagnosis, treatment choice, and possible outcomes. This fragmentation sometimes leads to an ambiguous definition of PNIs and the impossibility of exchanging crucial information between different physicians and healthcare structures, which can create confusion in the choice of therapeutic strategies and timing of surgery. MATERIALS: The authors retrospectively analyzed a group of 24 patients treated in their center and applied a new classification for PNI injuries. They chose (a) five injury-related factors, namely nerve involved, lesion site, nerve type (whether motor, sensory or mixed), surrounding tissues (whether soft tissues were involved or not), and lesion type-whether partial/in continuity or complete. An alphanumeric code was applied to each of these classes, and (b) four prognostic codes, related to age, timing, techniques, and comorbidities. RESULTS: An alphanumeric code was produced, similar to that used in the AO classification of fractures. CONCLUSIONS: The authors propose this novel classification for PNIs, with the main advantage to allow physicians to easily understand the characteristics of nerve lesions, severity, possibility of spontaneous recovery, onset of early complications, need for surgical treatment, and the best surgical approach. LEVEL OF EVIDENCE: according to the Oxford 2011 level of evidence, level 2.

RESUMO

INTRODUCTION: Recent studies have allowed a great improvement in understanding elbow and forearm traumatic injuries. Simple elbow dislocations combined with forearm injuries have been occasionally reported in the literature. The aim of this study was to detect the possible patterns of simple elbow dislocations and forearm fracture-dislocations, providing a classification scheme to guide surgical treatment. MATERIALS AND METHODS: PubMed search was performed to find combination of simple elbow dislocation and forearm joint injury, between 2000 and 2020, including clinical studies and case report. All articles related to pediatric patient or with complex elbow dislocation were excluded. After identification, articles were analyzed for the description of injury patterns reported according to locker-based classification system of forearm joint injuries. RESULTS: Finally, 15 articles were included. Most of the patients sustained high-energy trauma. According to locker-based classification system, simple elbow dislocation was combined with: MRUJ and DRUJ Galeazzi injury (2IR.3), PRUJ and MRUJ injury (1.2I), PRUJ and MRUJ injury with radial shaft fracture (1.2IR), PRUJ and MRUJ injury with ulnar shaft fracture (1.2 IU), PRUJ and MRUJ injury with radial and ulnar shaft fracture (1.2IRU), PRUJ MRUJ DRUJ Essex-Lopresti injury (1.2I.3), and PRUJ MRUJ DRUJ injury with radial shaft fracture (1.2IR.3). Thirteen out of 15 patients undergo surgical treatment. Clinical results were overall favorable. CONCLUSIONS: Simple elbow dislocation combined with forearm joint injury is an uncommon traumatic pattern usually secondary to high-energy trauma. A thorough knowledge of elbow and forearm biomechanics, and classification of anatomical lesion is mandatory for a successful treatment.

RESUMO

In this study, we investigated the relationship between sensory abnormalities evaluated by quantitative sensory testing (QST) and alexithymia, depression and anxiety in patients with neuropathic pain involving the upper limbs. We enrolled 62 patients (34 with carpal tunnel syndrome, 7 with brachial plexopathy, 3 with cervical painful radiculopathy, 5 with ulnar entrapment neuropathy at elbow and 13 with post-burn hypertrophic scars) and 48 healthy controls. All underwent nerve conduction studies (NCS), evaluation of cold, heat pain and vibration detection threshold (VDT) by QST and evaluation of alexithymia by Toronto Alexithymia Scale (TAS-20), depression by Beck Depression Inventory II (BDI-II), anxiety by State-Trait Anxiety Inventory (STAI-Y), level of psychological distress by 12-item General Health Questionnaire (GHQ-12) and perceived social support by the Multidimensional Scale of Perceived Social Support (MSPSS). The general linear model analysis revealed a significant relationship between TAS-20 overall and TAS-20 sub-score for difficulty identifying feelings and VDT z-scores in the left index with no interaction by year of education and sensory NCS results. Our results demonstrated the association between impairment of vibratory sensation of the left hand, reflecting cutaneous mechanoceptor dysfunction, and alexithymia, particularly the difficulty to identify feelings. The importance of delivering to patients with neuropathic pain personalized care that takes into account not only the neurophysiological aspects but also the aspects of mental functioning is discussed.

RESUMO

Cold intolerance and pain can be a substantial problem in patients with peripheral nerve injury. We aimed at investigating the relationships among sensory recovery, cold intolerance, and neuropathic pain in patients affected by upper limb peripheral nerve injury (Sunderland type V) treated with microsurgical repair, followed by early sensory re-education. In a cross-sectional clinical study, 100 patients (male/female 81/19; age 40.5 ± 14.8 years and follow-up 17 ± 5 months, mean ± SD), with microsurgical nerve repair and reconstruction in the upper extremity and subsequent early sensory re-education, were evaluated, using Cold Intolerance Symptoms Severity questionnaire-Italian version (CISS-it, cut-off pathology >30/100 points), CISS questionnaire-12 item version (CISS-12, 0-46 points-grouping: healthy that means no cold intolerance [0-14], mild [15-24], moderate [25-34], severe [35-42], very severe [43-46] cold intolerance), probability of neuropathic pain (DouleurNeuropathique-4; [DN4] 4/10), deep and superficial sensibility, tactile threshold (monofilaments), and two-point discrimination (cutoff S2; Medical Research Council scale for sensory function; [MRC-scale]). A high CISS score is associated with possible neuropathic pain (DN4 ≥ 4). Both a low CISS-it score (ie, < 30) and DN4 < 4 is associated with good sensory recovery (MRC ≥ 2). In conclusion patients affected by upper limb peripheral nerve injuries with higher CISS scores more often suffer from cold intolerance and neuropathic pain, and the better their sensory recovery is, the less likely they are to suffer from cold intolerance and neuropathic pain.

RESUMO

This brief clinical report describes our experience with virtual surgical planning in a case of mandibulectomy and mandibular reconstruction with a double barrel vascularized osteofasciocutaneous fibula free flap and immediate implant placement in a case of mandibular ameloblastoma. Fibular segments were positioned to obtain the best result both for masticatory function and for aesthetic facial appearance. Furthermore, in this particular case, as well as being positioned for future masticatory rehabilitation, the implants have served to stabilize the fibula segments in the reconstructive intraoperative phase. A superimposition of programed surgery and 6 months postoperative computed tomography scan was performed and results are presented.

RESUMO

Cortical plasticity is a finely regulated process that allows the central nervous system (CNS) to change in response to internal and external stimuli. While these modifications occur throughout normal brain development, interestingly, they are also elicited after peripheral nerve injury and surgery. This article provides an overview of the principle mechanisms of synaptic, neuronal, cortical and subcortical neuroplasticity, with special attention to cortical and subcortical modifications-as suggested by modern neuroimaging techniques-after peripheral nerve surgery. The main nerve transfer techniques for the superior extremities and their effect on cortical plasticity are also described.

RESUMO

INTRODUCTION: Sarcopenia is a clinical syndrome characterized by the reduction in muscle mass, strength and physical ability. Although proximal femur fractures are one of the major burdens affecting the ageing population, distal radius fractures are equally important for frequency, clinical and social consequences. The aim of this study is to evaluate the incidence of sarcopenia in distal radius fractures and clinical implications in functional recovery. MATERIALS AND METHODS: Scopus and PubMed search was performed to find relationship between sarcopenia and distal radius fractures. Literature search was performed between 2009 and 2019 including clinical trials and clinical studies related to "sarcopenia and distal radius fracture" and "sarcopenia and wrist fracture". After identification, studies were screened and analysed through the Oxford Level of Evidence. RESULTS: According to the inclusion and exclusion criteria, five articles were included. Four articles analysed the incidence of sarcopenia and its role as a risk factor in patients with distal radial fractures, while one article focused on sarcopenia and clinical results of surgical treatment of distal radius fractures. Incidence of sarcopenia in patients older than 50 years with distal radius fracture varied between 29.7% and 31.7%. Patients with distal radial fractures did not show a significant inferior muscle mass than control group in examined population. Functional results of surgery were significantly inferior in sarcopenic patients than control group (no sarcopenia). CONCLUSIONS: About 30% of patients older than 50 years with distal radius fracture suffered by sarcopenia; sarcopenic patients surgically treated had worse clinical results than no sarcopenic patients. Further studies with larger samples are needed to confirm these preliminary results.

RESUMO

BACKGROUND: Monteggia, Galeazzi, and Essex-Lopresti injuries are the most common types of fracture-dislocation of the forearm. Uncommon variants and rare traumatic patterns of forearm fracture-dislocations have sometimes been reported in literature. In this study we systematically review the literature to identify and classify all cases of forearm joint injury pattern according to the forearm joint and three-locker concepts. METHODS: A comprehensive search of the PubMed database was performed based on major pathological conditions involving fracture-dislocation of the forearm. Essex-Lopresti injury, Monteggia and Galeazzi fracture-dislocations, and proximal and/or distal radioulnar joint dislocations were sought. After article retrieval, the types of forearm lesion were classified using the following numerical algorithm: proximal forearm joint 1 [including proximal radioulnar joint (PRUJ) dislocation with or without radial head fractures], middle radioulnar joint 2, if concomitant radial fracture R, if concomitant interosseous membrane rupture I, if concomitant ulnar fracture U, and distal radioulnar joint 3 [including distal radioulnar joint (DRUJ) dislocation with or without distal radial fractures]. RESULTS: Eighty hundred eighty-four articles were identified through PubMed, and after bibliographic research, duplication removal, and study screening, 462 articles were selected. According to exclusion criteria, 44 full-text articles describing atypical forearm fracture-dislocation were included. Three historical reviews were added separately to the process. We detected rare patterns of two-locker injuries, sometimes referred to using improper terms of variant or equivalent types of Monteggia and Galeazzi injuries. Furthermore, we identified a group of three-locker injuries, other than Essex-Lopresti, associated with ulnar and/or radial shaft fracture causing longitudinal instability. In addition to fracture-dislocations commonly referred to using historical eponyms (Monteggia, Galeazzi, and Essex-Lopresti), our classification system, to the best of the authors' knowledge, allowed us to include all types of dislocation and fracture-dislocation of the forearm joint reported in literature. According to this classification, and similarly to that of the elbow, we could distinguish between simple dislocations and complex dislocations (fracture-dislocations) of the forearm joint. CONCLUSIONS: All injury patterns may be previously identified using an alphanumeric code. This might avoid confusion in forearm fracture-dislocations nomenclature and help surgeons with detection of lesions, guiding surgical treatment. LEVEL OF EVIDENCE: V.

RESUMO

BACKGROUND: The aim of the current study is to investigate the first and second lumbrical nerves as potential fibers donors to the deep motor branch of the ulnar nerve to avoid intrinsic atrophy in high ulnar nerve injuries. METHODS: Sixteen fresh frozen cadaveric hands were dissected, the radial lumbrical nerves accessed, and a coaptation, either in reverse end-to-side or in double end-to-side through a bridge nerve graft, was created to the deep motor branch of ulnar nerve. Semithin sections were taken from samples of donor and recipient nerves for qualitative (nerve architecture) and quantitative studies (fiber count and donor/recipient ratio). RESULTS: The first lumbrical showed a robust trunk and a superior axon density (9,126.50 ± 2,923.41 axons/mm2 ) to the ulnar motor branch (7,506.50 ± 1,137.50 axons/mm2 distal to the opponens tunnel and 7,947.75 ± 1,741.24 axons/mm2 before its terminal branching); the ulnar motor branch showed a higher axon number (2,633.51 ± 410.00 distal to the opponens tunnel and 2,345.75 ± 2,101.56 before its terminal branching) than the first lumbrical (1,410.56 ± 823.89); section areas occupied by axons were higher in proximal (0.20 ± 0.16) and distal (0.26 ± 0.20) ulnar samples than the first lumbrical (0.17 ± 0.16). Donor/recipient ratio first lumbrical/deep motor branch of the ulnar nerve were 1:1.86 (distal to the opponens tunnel) and 1:1.67 (at its terminal branching); data about the second lumbrical were ruled out because of bias. CONCLUSIONS: A transfer from the first lumbrical nerve to the deep motor branch of the ulnar nerve in palm is suitable to avoid intrinsic atrophy.

RESUMO

INTRODUCTION: Essex-Lopresti lesion (ELL) is a severe injury. Most of ELL is recognized in chronic phase representing a therapeutic challenge for orthopaedic surgeons. The aim of this systematic review is to highlight and criticize current concepts in the surgical treatment. MATERIALS AND METHODS: The search was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guideline. A comprehensive research of Pubmed database was made using the following Mesh term: ((Essex-Lopresti injury) OR (Essex Lopresti) OR (distal radio ulnar dissociation) OR (distal radio ulnar dislocation) OR (longitudinal forearm instability)). Quality assessment of each article was performed according to Coleman score by two authors. RESULTS: Eight full articles were included to the systematic review. Surgical treatment was differentiated in five categories according to the most common procedure reported in clinical series. The mean Coleman Score was 51.13 ± 9.76. DISCUSSION: Case series reported in the literature include a limited number of patients with chronic ELL. Currently, salvage procedure devoted to treat a wrong diagnosis and an incorrect treatment is used. Radial head replacement together with ulnar shortening osteotomy and interosseous membrane reconstruction are the most common treatments of choice, but at present, there is not yet a shared scheme of management for patients with chronic ELL. CONCLUSIONS: According to current literature, a case-by-case treatment must always be considered. Further investigations, with higher level of evidence, quality of study design, and number of patients, are needed to better assess clinical results and complication of each technique. LEVEL OF EVIDENCE: IV.

RESUMO

BACKGROUND: Preclinical training in perforator flap harvesting is typically conducted on living animal models; however, repeated training is not possible with these models because of ethical and/or economical constraints. We describe an anterolateral thigh flap (ALT flap) training model using chicken thigh that seems to be an appropriate training model prior, for example, to raise a perforator flap in a living rat or swine model. METHODS: A total of 10 chicken legs were used in this study. Six chicken legs were anatomically dissected to confirm the presence of the perforator and to identify the main vascular tree. In four chicken legs, a skin flap was planned based on the perforator and intramuscular dissection was performed under magnification. RESULTS: The perforator was identified in all dissections and was consistently found 3 cm above the line extending from the patella to the head of the femur in its third proximal. Proximally, the mean diameter of the artery and vein was 0.56 (σ = 0.04) and 0.84 (σ = 0.06) mm, respectively. The mean dissection time to raise the flap was 88 (σ = 7) min. CONCLUSION: This is the first description of a nonliving biological simulation model for training in perforator flap dissection that mimics an ALT flap. As an ex vivo chicken model, it is a cost effective and readily accessible model suitable for repeated practice.

RESUMO

Spinal cord injury (SCI) is very common, most frequently resulting from motor vehicle accidents and falling from a height. Often, SCI occurs at the cervical level, resulting in tetraplegia, which consists of loss of effective arm and/or hand function. For these patients, hand function is considered the most desired function, above bowel, bladder and sexual function. Fortunately, understanding about nerve and tendon transfers is steadily growing, providing new surgical solutions for functional restoration in tetraplegia patients. The primary aim of this systematic review of the literature is to assess all the various ways to improve upper-limb function, using both nerve transfers and classical tendon transfers in patients suffering from tetraplegia. Surgical indications, optimum timing and contraindications were reviewed. In accordance with the International Classification for Surgery of the Hand in Tetraplegia, ten subgroups of tetraplegic patients were analysed and a proposal for treatment combining nerve and tendon transfers formulated for each subgroup, seeking alternatives to classical surgical strategies. We also sought to propose strategies that, in instances of failure, still would allow for the use of some classical surgical approach. Starting with traditional management, we proposed new strategies using tenodesis and tendon transfers in association with nerve surgery. We believe that the suggestions described in the current paper could both improve and complete current surgical strategies and contribute to ensuring that more patients benefit from these options in future.

RESUMO

The amnion muscle combined graft (AMCG) conduits showed good clinical results in peripheral nerves gap repair. It combines the human amniotic membrane with autologous skeletal muscle fibres. These results seem attributable to the biological characteristics of human amniotic membrane: Pluripotency, anti-inflammatory and low immunogenicity.We here evaluate the final outcome of nerve regeneration morphologically and functionally, across the AMCG compared to nerve autograft. Fourteen Wistar rats were divided into two groups: In Group A, including 6 rats, the left forelimb was treated performing a 1.5 cm length gap on median nerve that was then reconstructed with a reverse autograft. In Group B, including 8 rats, the gap was reconstructed with AMCG. Functional results were evaluated at 30, 60 and 90 days performing grasping tests. Morphological and stereological analyses were performed at T90 using high-resolution light microscopy and design-based stereology. The AMCG conduits revealed nerve fibres regeneration and functional recovery. Functional recovery was observed in both groups with AMCG conduits group showing lower values and a regeneration of median nerves with more myelinated fibres with the same axon size, but thinner myelin than the autograft group. Though the autograft remains the gold standard to restore wide nerve gaps, the AMCG conduit has proved to be effective in enabling nerve regeneration through a critical rat's nerve gap of 15 mm. These findings empirically support the great clinical results obtained using AMCG conduit to restore traumatic nerve's gap from 3 to 6 cm of mixed forearm nerves.

RESUMO

During recent decades, the concept of surgical treatment of malignant bone and soft tissue sarcomas has evolved, with the aim of preserving limb function. In this paper we report a case of metatarsal reconstruction by means of serratus and rib free flap after excision of a synovial sarcoma located in the dorsal aspect of the midfoot. Five years after the operation, the patient was free from recurrence and recovered full foot function. Amputation has been widely used in the past and this procedure still remains a valuable option when limb salvage is not possible. Nevertheless, in selected cases, reconstruction by means of composite free flaps may be successfully used for limb preservation in the treatment of malignant foot tumors after surgical excision.

RESUMO

BACKGROUND: The rate of acute infection after surgery for proximal humeral fractures is not known. The aims of this study were to report the incidence and to analyze the risk factors for infection after proximal humeral fracture treatment. MATERIALS AND METHODS: We report a retrospective multicenter study of 452 proximal humeral fractures. Data were modeled by use of univariate and/or linear regression analyses to determine the odds ratio (OR). A logistic regression analysis was used to check for demographic and other characteristics with the potential to confound a true association between risk factors and infection. RESULTS: The mean age was 62.1 years, and 314 patients were female patients. Of the patients, 18 (4%) had an acute infection. The factors that correlated with infection were length of surgery (OR, 1.009; P = .05), preoperative skin preparation with chlorhexidine gluconate (OR, 0.13; P = .008), and prophylactic antibiotic (OR, 10.73; P = .03). The delay to surgery was close to achieving significance (OR, 1.71; P = .06). CONCLUSION: This study suggests that washing the shoulder with chlorhexidine gluconate and avoiding the use of first-generation cephalosporin in favor of more effective prophylactic therapy are effective at reducing the risk of infection after treatment for proximal humeral fractures.

RESUMO

Nerve grafting, tendon transfer and joint fusion are routinely used to improve the upper limb function in patients with brachial plexus palsies. Newer techniques have been developed that provide additional options for reconstruction. Nerve transfer is a tool for restoring upper limb function in total root avulsions where nerve grafting is not possible. In partial brachial plexus injuries, nerve transfers can greatly improve shoulder, elbow, wrist and hand function. Intraoperative electrical stimulation can be used to diagnose precisely which nerve is injured and to choose which nerve fascicles should be transferred. Finally, measuring the postoperative outcome can improve the evaluation of our techniques. The aim of this article was to present the current techniques used to treat patients with brachial plexus injury.

RESUMO

Background: Virtual surgical planning has become a well-established practice in head and neck surgery. In oncological surgery, it permits the achievement of safe margins resections and ensures functional reconstructions and optimal esthetic outcomes. This study aimed to evaluate the long-term outcomes after virtually planned mandibular microvascular reconstruction, focusing on functional and esthetic results, as well as health-related quality of life. Methods: A long-term retrospective evaluation of 17 patients with oral cavity malignancy who underwent computer-assisted mandibular resection and reconstruction was performed. Functional and esthetic outcomes were analyzed using the EORTC, QLQ-C30, H&N35, and FACE-Q questionnaires. Results: Time since reconstruction ranged from 7 to 14 years. Patients reported high functional levels on the QLQ-C30 functional scales but lower scores on H&N35. On FACE-Q, patients demonstrated higher appraisal and satisfaction with their smiles compared to their overall facial appearance. Conclusions: In this retrospective case series, patients undergoing computer-assisted mandibular reconstruction for oral malignancies achieved good long-term functional and esthetic outcomes. Although limited by the small sample size, these results support the enduring benefits of virtual planning for mandibular reconstruction. To minimize declines in function and appearance, considerations should include immediate dental implants, enhanced reconstruction of the temporomandibular joint, newer methods of radiotherapy to minimize xerostomia, and oral exercises to prevent trismus.
