What to Know about Antimicrobial Coatings in Arthroplasty: A Narrative Review.

Periprosthetic joint infections (PJIs) are one of the most worrying complications orthopedic surgeons could face; thus, methods to prevent them are evolving. Apart from systemic antibiotics, targeted strategies such as local antimicrobial coatings applied to prosthetics have been introduced. This narrative review aims to provide an overview of the main antimicrobial coatings available in arthroplasty orthopedic surgery practice. The search was performed on the PubMed, Web of Science, SCOPUS, and EMBASE databases, focusing on antimicrobial-coated devices used in clinical practice in the arthroplasty world. While silver technology has been widely adopted in the prosthetic oncological field with favorable outcomes, recently, silver associated with hydroxyapatite for cementless fixation, antibiotic-loaded hydrogel coatings, and iodine coatings have all been employed with promising protective results against PJIs. However, challenges persist, with each material having strengths and weaknesses under investigation. Therefore, this narrative review emphasizes that further clinical studies are needed to understand whether antimicrobial coatings can truly revolutionize the field of PJIs.

Direct anterior approach hip arthroplasty: How to reduce complications - A 10-years single center experience and literature review.

BACKGROUND: The direct anterior approach for total hip arthroplasty (DAA-THA) is increasing in popularity due to some advantages such as less surgical trauma, minimal dissection of soft tissues, shorter rehabilitation times, faster return to daily activities, lower incidence of dislocation. On the other hand, the literature reports a high rate of intraoperative complications, with many different rates and complication types in the published papers. AIM: To analyze our complications comparing results with the literature; to report measures that we have taken to reduce complications rate. METHODS: All DAA-THA patients with one year minimum follow up who were operated at a single high-volume centre, between January 2010 and December 2019 were included in this retrospective study. All surgeries were performed using cementless short anatomical or straight stems and press fit cups. Patients' follow-up was performed, at 6 wk, 3 mo, then annually post-surgery with clinical and radiological evaluation. Primary outcomes were stem revision for aseptic loosening and all-cause stem revision. Second outcome was intra-operative and post-operative complications identification. RESULTS: A total of 394 patients underwent DDA-THA from January 2010 and December 2019, for a total of 412 hips; twelve patients lost to follow-up and one patient who died from causes not related to surgery were excluded from the study. The average age at the time of surgery was 61 years (range from 28 to 78 years). Mean follow-up time was 64.8 mo (range 12-120 mo). Seven stems were revised. One cortical perforation, one trochanteric and lateral cortical wall intraoperative fracture, one diaphyseal fracture, three clinically symptomatic early subsidence and one late aseptic loosening. We also observed 3 periprosthetic fractures B1 according to the Vancouver Classification. Other minor complications not requiring stem revision were 5 un-displaced fractures of the calcar region treated with preventive cerclage, one early infection, one case of late posterior dislocation, 18 case of asymptomatic stem subsidence, 6 cases of lateral cutaneous femoral nerve dysesthesia. CONCLUSION: DAA is associated to good outcomes and lower incidence of dislocation. Complication rate can be reduced by mindful patient selection, thorough preoperative planning, sufficient learning curve and use of intraoperative imaging.

DIPHOS® nail for proximal humeral fractures: our experience with more than 190 procedures and surgical tips.

AIM: evaluate the outcome of proximal  humeral nailing over 5 years follow-up, focusing  on possible complications. Secondary endpoint is the description and analysis of some technical notes to simplify surgical procedure. MATERIALS AND METHODS: the cohort is composed by 194 fractures fixed with short nail. Neer Classification was used to assess the type of fracture; Deltoid Tuberosity Index (DTI) was applied to verify local bone quality. Follow-up with X-rays and orthopaedic evaluation was conducted on every operated subject. RESULTS: mean follow up of the study was 25.4 months. We registered an average CMS score of 84.66 points for 2-parts fractures, 79.05 points for 3-part fractures and 68.62 points for 4-parts fractures. We obtained radiographical healing in 95.9% of patients (186/194) after 2.7 months on average. We recorded "very good" / "good" results in 90.3% of 2-parts fractures, 88.5% of 3-parts fractures and 46.2% of 4-part fractures. Overall complication rate was 10.3% (20/194 nails).  Second surgery was performed in 8.2% (16/194) of cases. CONCLUSION: intramedullary nailing is an effective treatment for 2 and 3-part fractures with relatively low incidence of complications, small surgical accesses and short surgical time. Future researches are necessary to analyze the results related to nailing in 4-fragment fractures, still uncertain and influenced by multiple factors. The presence of the intramedullary nail reduces the lever arm of the screws making the osteosynthesis more reliable. Modern nails guarantee angular stability for proximal cancellous screws and allows 1 or 2 screws at calcar level to get a valid medial support.

Clinical Activities, Contaminations of Surgeons and Cooperation with Health Authorities in 14 Orthopedic Departments in North Italy during the Most Acute Phase of Covid-19 Pandemic.

Background: From 10 March up until 3 May 2020 in Northern Italy, the SARS-CoV-2 spread was not contained; disaster triage was adopted. The aim of the present study is to assess the impact of the COVID-19-pandemic on the Orthopedic and Trauma departments, focusing on: hospital reorganization (flexibility, workload, prevalence of COVID-19/SARS-CoV-2, standards of care); effects on staff; subjective orthopedic perception of the pandemic. Material and Methods: Data regarding 1390 patients and 323 surgeons were retrieved from a retrospective multicentric database, involving 14 major hospitals. The subjective directors' viewpoints regarding the economic consequences, communication with the government, hospital administration and other departments were collected. Results: Surgical procedures dropped by 73%, compared to 2019, elective surgery was interrupted. Forty percent of patients were screened for SARS-CoV-2: 7% with positive results. Seven percent of the patients received medical therapy for COVID-19, and only 48% of these treated patients had positive swab tests. Eleven percent of surgeons developed COVID-19 and 6% were contaminated. Fourteen percent of the staff were redirected daily to COVID units. Communication with the Government was perceived as adequate, whilst communication with medical Authorities was considered barely sufficient. Conclusions: Activity reduction was mandatory; the screening of carriers did not seem to be reliable and urgent activities were performed with a shortage of workers and a slower workflow. A trauma network and dedicated in-hospital paths for COVID-19-patients were created. This experience provided evidence for coordinated responses in order to avoid the propagation of errors.

Do standards of care and early outcomes of periprosthetic fractures change during the COVID-19 pandemic? A multicentre study.

BACKGROUND: Periprosthetic fractures (PPFs) are a growing matter for orthopaedic surgeons, and patients with PPFs may represent a frail target in the case of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The purpose of this study is to investigate whether hospital reorganisations during the most severe phase of the SARS-CoV-2 pandemic affected standards of care and early outcomes of patients treated for PPFs in Northern Italy. MATERIALS AND METHODS: Data were retrieved from a multicentre retrospective orthopaedics and traumatology database, including 14 hospitals. The following parameters were studied: demographics, results of nasopharyngeal swabs, prevalence of coronavirus disease 2019 (COVID-19), comorbidities, general health status (EQ-5D-5L Score), frailty (Clinical Frailty Scale, CFS), pain (visual analogue scale, VAS), anaesthesiologic risk (American Society of Anaesthesiology Score, ASA Score), classification (unified classification system, UCS), type of operation and anaesthesia, in-hospital and early complications (Clavien-Dindo Classification, CDC), and length of stay (LOS). Data were analysed by means of descriptive statistics. Out of 1390 patients treated for any reason, 38 PPFs were included. RESULTS: Median age was 81 years (range 70-96 years). Twenty-three patients (60.5%) were swabbed on admission, and two of them (5.3%) tested positive; in three patients (7.9%), the diagnosis of COVID-19 was established on a clinical and radiological basis. Two more patients tested positive post-operatively, and one of them died due to COVID-19. Thirty-three patients (86.8%) presented a proximal femoral PPF. Median ASA Score was 3 (range, 1-4), median VAS score on admission was 3 (range, 0-6), median CFS was 4 (range, 1-8), median EQ-5D-5L Score was 3 in each one of the categories (range, 1-5). Twenty-three patients (60.5%) developed post-operative complications, and median CDC grade was 3 (range, 1-5). The median LOS was 12.8 days (range 2-36 days), and 21 patients (55.3%) were discharged home. CONCLUSIONS: The incidence of PPFs did not seem to change during the lockdown. Patients were mainly elderly with comorbidities, and complications were frequently recorded post-operatively. Despite the difficult period for the healthcare system, hospitals were able to provide effective conventional surgical treatments for PPFs, which were not negatively influenced by the reorganisation. Continued efforts are required to optimise the treatment of these frail patients in the period of the pandemic, minimising the risk of contamination, and to limit the incidence of PPFs in the future. LEVEL OF EVIDENCE: IV.

Early mortality in hip fracture patients admitted during first wave of the COVID-19 pandemic in Northern Italy: a multicentre study.

BACKGROUND: Treatment of hip fractures during the coronavirus disease 2019 (COVID-19) pandemic has posed unique challenges for the management of COVID-19-infected patients and the maintenance of standards of care. The primary endpoint of this study is to compare the mortality rate at 1 month after surgery in symptomatic COVID-positive patients with that of asymptomatic patients. A secondary endpoint of the study is to evaluate, in the two groups of patients, mortality at 1 month on the basis of type of fracture and type of surgical treatment. MATERIALS AND METHODS: For this retrospective multicentre study, we reviewed the medical records of patients hospitalised for proximal femur fracture at 14 hospitals in Northern Italy. Two groups were formed: COVID-19-positive patients (C+ group) presented symptoms, had a positive swab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and received treatment for COVID-19; COVID-19-negative patients (C- group) were asymptomatic and tested negative for SARS-CoV-2. The two groups were compared for differences in time to surgery, survival rate and complications rate. The follow-up period was 1 month. RESULTS: Of the 1390 patients admitted for acute care for any reason, 477 had a proximal femur fracture; 53 were C+ but only 12/53 were diagnosed as such at admission. The mean age was > 80 years, and the mean American Society of Anesthesiologists (ASA) score was 3 in both groups. There was no substantial difference in time to surgery (on average, 2.3 days for the C+ group and 2.8 for the C- group). As expected, a higher mortality rate was recorded for the C+ group but not associated with the type of hip fracture or treatment. No correlation was found between early treatment (< 48 h to surgery) and better outcome in the C+ group. CONCLUSIONS: Hip fracture in COVID-19-positive patients accounted for 11% of the total. On average, the time to surgery was > 48 h, which reflects the difficulty of maintaining normal workflow during a medical emergency such as the present pandemic and notwithstanding the suspension of non-urgent procedures. Hip fracture was associated with a higher 30-day mortality rate in COVID-19-positive patients than in COVID-19-negative patients. This fact should be considered when communicating with patients and/or their family. Our data suggest no substantial difference in hip fracture management between patients with or without COVID-19 infection. In this sample, the COVID-19-positive patients were generally asymptomatic at admission; therefore, routine screening is recommended. LEVEL OF EVIDENCE: Therapeutic study, level 4.

Promising medium-term results of anterior approach with an anatomical short stem in primary hip arthroplasty.

BACKGROUND: In the last decade, the increase in the use of the direct anterior approach to the hip has contributed to the diffusion of the use of short stems in orthopedic surgery. The aim of the study is to verify the medium-term clinical and radiographic results of a cementless anatomic short stem in the anterior approach to the hip. We also want to verify whether the use of the standard operating room table or the leg positioner can affect the incidence of pre- and postoperative complications. MATERIALS AND METHODS: All total hip arthroplasty patients with a 1-year minimum follow-up who were operated using the MiniMAX stem between January 2010 and December 2019 were included in this study. Clinical evaluation included the Harris Hip Score (HHS), Western Ontario and McMaster Universities Hip Outcome Assessment (WOMAC) Score, and Short Form-36 (SF-36) questionnaires. Bone resorption and remodeling, radiolucency, osteolysis, and cortical hypertrophy were analyzed in the postoperative radiograph and were related to the final follow-up radiographic results. Complications due to the use of the standard operating room table or the leg positioner were evaluated. RESULTS: A total of 227 patients (238 hips) were included in the study. Average age at time of surgery was 62 years (range 38-77 years). Mean follow-up time was 67.7 months (range 12-120 months). Kaplan-Meier survivorship analysis after 10 years revealed 98.2% survival rate with revision for loosening as endpoint. The mean preoperative and postoperative HHS were 38.35 and 94.2, respectively. The mean preoperative and postoperative WOMAC Scores were 82.4 and 16.8, respectively. SF-36 physical and mental scores averaged 36.8 and 42.4, respectively, before surgery and 72.4 and 76.2, respectively, at final follow-up. The radiographic change around the stem showed bone hypertrophy in 55 cases (23%) at zone 3. In total, 183 surgeries were performed via the direct anterior approach (DAA) on a standard operating room table, and 44 surgeries were performed on the AMIS mobile leg positioner. Comparison between the two patient groups did not reveal significant differences. CONCLUSION: In conclusion, a short, anatomic, cementless femoral stem provided stable metaphyseal fixation in younger patients. Our clinical and radiographic results support the use of this short stem in the direct anterior approach. LEVEL OF EVIDENCE: IV.

The orthopaedic and traumatology scenario during Covid-19 outbreak in Italy: chronicles of a silent war.

BACKGROUND: From February 21, the day of hospitalisation in ICU of the first diagnosed case of Covid-19, the social situation and the hospitals' organisation throughout Italy dramatically changed. METHODS: The CIO (Club Italiano dell'Osteosintesi) is an Italian society devoted to the study of traumatology that counts members spread in public and private hospitals throughout the country. Fifteen members of the CIO, Chairmen of 15 Orthopaedic and Trauma Units of level 1 or 2 trauma centres in Italy, have been involved in the study. They were asked to record data about surgical, outpatients clinics and ER activity from the 23rd of February to the 4th of April 2020. The data collected were compared with the data of the same timeframe of the previous year (2019). RESULTS: Comparing with last year, overall outpatient activity reduced up to 75%, overall Emergency Room (ER) trauma consultations up to 71%, elective surgical activity reduced up to 100% within two weeks and trauma surgery excluding femoral neck fractures up to 50%. The surgical treatment of femoral neck fractures showed a stable reduction from 15 to 20% without a significant variation during the timeframe. CONCLUSIONS: Covid-19 outbreak showed a tremendous impact on all orthopaedic trauma activities throughout the country except for the surgical treatment of femoral neck fractures, which, although reduced, did not change in percentage within the analysed timeframe.

Acetabular de-escalation in hip revision.

BACKGROUND: The idea of ''de-escalation'' (DE) indicates an arthroplasty revision performed by changing a revision component by a primary component. Aim of this study is to verify if this technique can represent an option in case of cage or ring failure. METHODS: We observed five cases of revision hip cage loosening with complete allograft consolidation. This group of patients were revised with use of a primary cup and were specifically followed in ours institutions offices. Patients were clinically and radiologically followed every 6 months for the next two years and then annually Results: At final follow-up (15-2 years, mean 6 years) four patients (80%) showed a good recovery of their levels of activity. The mean Harris hip score improved from 20 points (range,7-38 points) preoperatively to 48 points (range, 16-88 points). At final radiological follow-up acetabular components were radiographically stable at the last follow-up. One patient (20%) at two years follow-up, was unable to walk without crutchies due to hip pain. X-rays showed cup loosening in all three zones. Patient was dissatisfied. Primary cup was revised with a Burch Schneider cage. CONCLUSIONS: De-escalation technique is a surgical option to consider in case of young patients, limited number of previous revisions and more than three years survivorship of loosened acetabular cage.

A preliminary experience with a new intramedullary nail for trochanteric fractures.

BACKGROUND AND AIM OF THE WORK: The worldwide incidence of fractures of the proximal end of the femur is increasing as the average age of the population rises. The current surgical gold treatment standard is intramedullary nail fixation. The Authors present their experience with the D-Nail system for intertrochanteric femur fractures. METHODS: From January 1st to February 21st 2020 (breakout of COVID-19 pandemic) 34 patients were treated with the D-Nail system: 11 with basicervical fractures, 16 with intertrochanteric stable fractures and 7 with intertrochanteric unstable fractures. In 11 cases, a single cephalic screw was used; in 23 cases, two of them were used. Distal locking was executed in 7 patients. Follow-up time ranged from 2 to 3 months. RESULTS: None of the reported intra- or post-operative complication was linked to the fixation device or the surgical technique. Patients were monitored with clinical and radiological checkups using modified Harris Hip Score to accurately evaluate the fluctuations in the rehabilitation period. CONCLUSION: The main advantages of this synthesis device are the proximal hole's peculiar shape, which allows the possibility to position one or two cephalic screws on the same nail, and the silicon coating, which provides numerous biological advantages. Distal locking was executed in selected cases only, based on fracture type. Optimum treatment involves rapid execution of surgery, minimal trauma during surgery, maximum mechanical stability, and rapid weight-bearing. Although our case number is small and follow-up time brief, our results are encouraging.

Contraceptive subcutaneous device migration: what does an orthopaedic surgeon need to know? A case report and literature review.

Subdermal contraceptive implant is approved in more than 60 countries and used by millions of women around the world. Although relatively safe in nature, their implantation and removal may be associated with potential complications, some of which may require surgical intervention. Two types of peripheral neurological complications are reported: complications related to compressive neuropathy caused by device decubitus and complications related to device improper removal. An healthy 35-year-old woman come to our attention for paresthesia from medial side of right elbow to fourth and fifth fingers. Tinel sign was positive on medial side of distal third of right arm, above the elbow, as well. Clinical history of patients revealed a subcutaneous placement of a etonogestrel implant 3 years before. Patients reported disappearing of tactile feeling of subcutaneous contraceptive implant since two months. At clinical examination, implant was not felt in its original subcutaneous place. X-rays control revealed its proximal and deep migration. Surgical exploration for subcutaneous contraceptive implant removal revealed it lying on the ulnar nerve. Patient referred immediate paresthesia disappearing after surgery. At 1 month follow up no motor or sensory alteration were evident. Removal of implants inserted too deeply must be carefully performed to prevent damages to nervous and vascular structures and it should be performed by operators who are very familiar with the anatomy of the arm. In case of chronic neuropathy caused by implant nerve compression only an appropriate patients information about rare but possible neuropathic symptoms related to device migration and a careful medical history collecting can avoid a mistaken diagnosis of canalicular syndrome.

Risk of stem undersizing with direct anterior approach for total hip arthroplasty.

PURPOSE: The direct anterior approach (DAA) for total hip arthroplasty (THA) is claimed to be as effective but less invasive than the conventional posterior approach (PA). However, the higher risk of femoral fracture and soft tissue damage cannot be underestimated. The present authors believe that the difficult femoral exposure and the surgeon's knowledge of possible complications related to femoral preparation may result in a higher rate of undersized stems when compared to PA, even when a short femoral component is employed to minimise these risks. METHODS: A retrospective study was performed to compare the effective adherence of surgical sizing to preoperative planning in a series of 112 short stem THAs, of which 59 were implanted through PA and 53 through DAA without intraoperative imaging, by a single surgeon skilled in both techniques. RESULTS: the frequency of stems smaller than expected was 3-times higher with DAA than with PA (54.72% vs 16.95%, p<0.001), while the frequency of stems at least 2 sizes smaller than expected was more than 6-times higher with DAA than with PA (24.53% vs 3.39%, p = 0.001). Conversely, no differences of size discrepancy distribution were found for cups and prosthetic heads. Postoperative x-rays confirmed an inferior mean canal fill in the DAA group, but excluded a different incidence of frontal malalignment between the groups. CONCLUSIONS: The technical difficulty of femoral preparation and the surgeon's knowledge of possible related complications might lead to implant undersized stems more frequently through DAA than through PA, especially if intraoperative imaging controls are not used.

Intravascular migration of a broken cerclage wire into the left heart.

This article describes a patient in whom a broken cerclage wire migrated from the left hip into the left ventricle. A 71-year-old woman was admitted to the authors' hospital for preoperative examination before femoral hernia repair. Chest radiograph showed a metallic wire in the left ventricle. Twenty-four years earlier, she had a revision arthroplasty. During revision surgery, fragments of the osteotomy were fixed to the femur with multiple cerclage wires. During the past 5 years, radiographic follow-up showed progressive multiple ruptures of cerclage wires. The cerclage wiring was not removed because the patient had no related clinical symptoms. Radiograph of the left hip showed a well-fixed cemented acetabular ring and an uncemented femoral stem with a healed trochanteric osteotomy. All cerclage wires were broken into multiple parts, and it was very difficult to determine which part had migrated into the heart. Thoracic computed tomography scan showed wire that had migrated into the anterior left ventricular myocardial wall at the atrioventricular level. The patient had no clinical symptoms. Electrocardiogram showed a normal sinus rhythm and right bundle branch block. Because of the high risk of surgical left ventriculotomy associated with searching for wire that had migrated into the myocardial wall, patient monitoring was planned. Definitive management of this complication constitutes a dilemma. Although this complication is highly unusual, the possibility of intracardiac migration of broken wire should be considered when deciding on prophylactic surgical removal of hardware after fracture or osteotomy healing.

Can viscosupplementation be used in the hip? An Italian perspective.

Viscosupplementation is the intra-articular administration of preparations containing hyaluronic acid or hyaluronate intended to restore the normal biological properties of hyaluronic acid normally found in synovial fluid. Infiltration of hyaluronic acid in the arthritic hip is a more recent technique than viscosupplementation of the knee due to the greater technical difficulty of infiltration to the hip, which requires fluoroscopic or ultrasound guidance. The introduction of high-molecular-weight hyaluronic acid in the treatment permits a single administration and has helped diffuse hip infiltration treatment. A single infiltration reduces patient discomfort caused by the procedure and allows treatment of a larger number of patients. Although the literature has unequivocally proven the possibility of reducing pain in patients affected by hip arthritis following infiltration, the molecular weight and density, the number of infiltrations required for long-term results, and the most appropriate indications for infiltration treatment have yet to be clarified. Selecting the patient is the first obstacle to be overcome. Therefore, infiltration should be considered as an option for patients with initial pain symptoms who have not yet been listed for joint prosthesis surgery. The radiographic criteria require at least a partly preserved joint space, and the clinical criteria of persistent hip pain and full joint mobility seem to be sufficiently effective for selection.

Bilateral double osteotomy in severe torsional malalignment syndrome: 16 years follow-up.

BACKGROUND: Torsional malalignment syndrome (TMS) is a well defined condition consisting of a combination of femoral antetorsion and tibial lateral torsion. The axis of knee motion is medially rotated. This may lead to patellofemoral malalignment with an increased Q angle and chondromalacia, patellar subluxation and dislocation. Conservative management is recommended in all but the most rare and severest cases. In these cases deformity correction requires osteotomies at two levels per limb. MATERIALS AND METHODS: From 1987 to 2002 in our institution three patients underwent double femoral and tibial osteotomy for TMS bilateral correction (12 osteotomies). All patients were reviewed at mean follow-up of 16 years. RESULTS: At final follow-up no patients reported persistence of knee or hip pain. At clinical examination both lower limbs showed a normal axis and a normal patella anterior position. Pre-operative femoral version measurement showed an average hip internal rotation of 81.5° (range 80°-85°) and average hip external rotation of 27.2° (10°-40°). Thigh-foot angle measurement showed an average value of 38.6° (32°-45°). At final follow-up femoral version measurement showed an average hip internal rotation of 49° (range 45°-55°) and average hip internal rotation of 44.3° (20°-48°) (Figs. 1, 2, 3, 4, 5, 6). Thigh-foot angles measurement showed an average value of 21.6° (18°-24°) outward. CONCLUSION: We recommend a clinical, radiographical and CT scan evaluation of all torsional deformity. In cases of significant deformity, internally rotating the tibia alone is not sufficient. Ipsilateral outward femoral and inward tibial osteotomies are our current recommendation for TMS, both performed at the same surgical setting.

The CLOS MB intramedullary nail for the treatment of pathological femoral shaft lesions.

Advances in systemic and radiation therapy have led to considerable improvement in the prognosis of patients with metastatic disease. As a result, orthopedic surgeons are being asked with increasing frequency to evaluate and treat the manifestations of skeletal metastases. Intramedullary nailing is a valuable technique for stabilizing (impending) pathological femoral fractures or osteolytic lesions. From January 1999 to January 2001 we treated 5 patients for skeletal metastases in the diaphyseal region of the femur. One month after surgical stabilization of the pathological lesion involving the femur, we observed significant improvement in quality of life, including pain relief and early ambulation.

Low-velocity gunshot fractures of the tibia.

A gunshot-related fracture is a unique type of open fracture. Bullet-induced fractures of the tibia may be encountered in any urban or rural setting as a result of hunting or cleaning mishaps or, perhaps more frequently, of criminal activity. For surgeons with limited experience, there is a bewildering range of apparently contradictory advice concerning their management. This article reports a case of a 53-year-old man with a highly comminuted bullet-induced shaft fracture of the tibia received during hunting activity. The patient was treated with a unilateral external fixator and vascularized flap for skin reconstruction. Six months after surgery, the external fixator was removed at clinical and radiological evidence of healing. At 1 year follow-up, the patient obtained complete healing and returned to normal activity.
