COVID-19 Resulted in Reduction Trainee Bedside Experience, But No Reduction in Surgical Experience.

Purpose: Because of the concerns regarding residency process during the pandemic, this study aimed to investigate the volume of clinical interactions of orthopaedic residents at a tertiary hospital by reporting the number of patients treated in the outpatient clinic, inpatient ward, and operating room. Methods: This retrospective chart study evaluated variables such as volume of clinical interactions of orthopaedic residents at a tertiary hospital by reporting the number of patients treated in the outpatient clinic, inpatient ward, and operating room, from an orthopaedic department in a tertiary trauma center throughout the COVID-19 pandemic era. Comparing these measures was an indirect evaluation tool for measuring the amount of work completed and clinical exposure gained by the residents. Results: Occupancy percentage, hospitalization days, admissions to the department, and attendance of the outpatient clinic were all decreased during the pandemic. No significant changes were evident in the total number of surgeries nor the number of elective surgeries during the pandemic. Conclusions: Overall, a reduction in overall hospitalization days, admissions to the department, total number of visits in the outpatient clinic, and occupancy percentage of the ward was observed during COVID-19. However, there was no difference in the average number of monthly surgeries between the pre-COVID-19 and COVID-19 timeframes. Level of Evidence: Level III, retrospective comparative review.

Surgical stabilisation in equivocal pelvic ring injuries - Into the grey zone.

Pelvic ring injuries comprise a spectrum of bony, ligamentous and muscular injuries, described by several common classification systems. However, the majority of injuries lie in areas of intermediate severity, where complexity and variable nature make it extremely hard to define in detail. This fact and associated injuries make it extremely difficult to conduct randomised control trials, with purpose to direct treatment guidelines. Thus, special interest and expertise are required by pelvic trauma surgeons, while surgical indications and fixation methods rely on their experience, at least in part. Namely, a significant grey zone of indication exists. As fixation methods evolve, specifically percutaneous fixation using osseous fixation pathways, some injuries in which morbidity bound with surgical fixation was considered too high relative to its benefits, may be considered eligible for surgical treatment nowadays. Moreover, due to significant progress in the treatment of the acute polytrauma casualties, the survival rate increased over the years, emphasizing the effect of long-term morbidity and functional outcome of pelvic ring injuries. The purpose of this manuscript is to describe the equivocal areas of controversies, hence "the grey zone", and to provide the readership with up-to-date published data. We aimed to collect and detail clinical and radiological clues in the diagnosis of intermediate unstable anterior-posterior compression and lateral compression injuries, and for the selection of treatment methods and sequence. Recent publications have provided some insights into specific injury features that are correlated with increased chance of instability, pain and delay in ambulation. Specific focus is given to the utility of examination under anaesthesia in selected cases. Other publications surveyed the shared experience of pelvic trauma surgeons as for the classification, indication and treatment sequence of pelvic ring injuries. Although the data hasn't matured yet to a comprehensive treatment algorithm, it may serve clinicians well when making treatment decisions in the grey zone of pelvic ring injuries, and serve as a basis for future prospective studies.

Risk Factors for a Failed Transmetatarsal Amputation in Patients with Diabetes.

BACKGROUND: Transmetatarsal amputation (TMA) is a well-recognized limb-salvage procedure, often indicated for the treatment of diabetic foot infections. Currently, there is no widespread agreement in the literature with regard to the factors associated with failure of TMA. This study aimed to define risk factors for the failure of TMA, defined as below-the-knee or above-the-knee amputation, in patients with diabetes. METHODS: This retrospective cohort study included 341 patients who underwent primary TMA. Patients who had a revision to a higher level (the failed TMA group) were compared with those who did not have failure of the initial amputation (the successful TMA group). RESULTS: This study showed a higher frequency of renal impairment, defined as a high creatinine level and/or a previous kidney transplant or need for dialysis, in the failed TMA group (p = 0.002 for both). Furthermore, a Charlson Comorbidity Index (CCI) threshold value of 7.5 was identified as the optimal predictive value for failure of TMA (p = 0.002), and patients with a CCI of >7.5 had a median time of 1.13 months until the initial amputation failed. CONCLUSIONS: TMA is associated with a high risk of revision. CCI may be used as a preoperative selection criterion, as 71.8% of patients with a CCI of >7.5 had failure of the TMA. LEVEL OF EVIDENCE: Therapeutic Level III . See Instructions for Authors for a complete description of levels of evidence.

A comparison between Austin-Moore and Corail prosthesis regarding intraoperative periprosthetic femur fractures in hip hemiarthroplasty.

Hip hemiarthroplasty is considered the treatment of choice for displaced femoral neck fractures in elderly less active patients. One important complication of this procedure is an intraoperative periprosthetic femur fracture (IPF), which may lead to poor functional outcome and may increase morbidity and mortality. Our primary aim in this study is to compare between Austin-Moore and Corail prosthesis regarding IPFs. Our secondary aim is to assess patient and surgical technique related risk factors for the development of this complication. Inclusion criteria included patients older than 65 years of age who had a displaced femoral neck fracture and were operated for hip hemiarthroplasty between the years 2014-2018. Patient-specific data was collected retrospectively including age, gender, comorbidities, pre-injury ambulatory status, duration of surgery, surgical approach, use of Austin-Moore or Corail prosthesis, surgeon's experience and type of anesthesia applied. In addition, radiographs were reviewed for measurement of calcar to canal ratio (CDR) and classification of Dorr canal type. 257 patients with an average age of 83.7 years were enrolled in the study. 118 patients (46%) were treated with an Austin-Moore prosthesis, while 139 (54%) were treated with a Corail prosthesis. A total of 22 patients (8.6%) had intraoperative fractures. Fracture prevalence was significantly higher in the Corail group compared with the Austin-Moore group (12.2% vs. 4.2%, p = 0.025). The majority of patients had a Dorr A type femoral canal, while the rest had Dorr B type canal (70% vs. 30%). There was no difference in fracture prevalence between Dorr A and B canal type patients. We didn't find any significant risk factor for developing an IPF, neither patient wise (age, gender, and comorbidities) nor surgical technique related (surgical approach, type of anesthesia, and surgeon's experience). Intraoperative periprosthetic fracture prevalence was significantly higher in the Corail patient group compared with the Austin-Moore group. This may be an important advantage of the Austin-Moore prosthesis over the Corail prosthesis.

Multiple trauma-induced, secondary osteoarthritis, knee Arthroplasty and technology: Conventional approach to an unconventional scenario.

A 49-year-old man was involved in a high-energy motor vehicle accident. Haemodynamic instability with multiple long bone fractures of lower limbs was the hallmarks of the injury. Closed fragmented fracture of left femur shaft and open displaced supracondylar fracture of the contralateral femur. Closed comminuted high-grade fracture of the Tibia plateau (Schatzker VI) was diagnosed bilaterally. 'Orthopaedic damage control' was initiated with bilateral 'cross knee' external fixation, followed by conversion to open reduction internal fixation of all fracture sits at 8 days later. The patient underwent nine subsequent hospitalisations, of which eight involved operative treatment. The interval from admission to last documented surgery was 7 years. The endpoint was total knee arthroplasty (TKA) with mega prosthesis of the left knee and a primary-type TKA in the right knee. Both arthroplasties were non-assisted, conventional procedures. Postoperative Western Onterio and McMaster Universities Arthritis Index (WOMAC) score was 85 at 9-year follow-up from the injury incurred.

[ANTERIOR HIP ARTHROPLASTY: EVOLUTION, REVOLUTION, OR AN ELAPSING TREND?]

INTRODUCTION: Over the years total hip arthroplasty had turned from a procedure indicated for elderly, low functioning patients, into a procedure indicated also for younger patients who are interested in a well-functioning hip joint to maintain their active lifestyle. Previously, posterior approach was most commonly utilized, however in recent years, due to the accumulating evidence regarding the advantages of the anterior approach, an increase in the prevalence of the anterior approach is noted. In contrast to other surgical approaches, the anterior approach "respects" inter-muscular and inter-nervous planes and therefore is perceived as associates with less pain, faster rehabilitation, and a good stability relative to other approaches. Thus, the anterior approach received the attention of both the orthopedic community and the patients who are interested in maintaining their active life routine. In contrast to the advantages associated with the anterior approach, there are some disadvantages that are unique to this approach such as technical difficulties, a challenging learning curve, and a relatively common impairment of the sensation of the lateral aspect of the operated thigh. Due to the increasing rates of total hip arthroplasty procedures that are performed via the anterior approach, there is a need for reviewing the different aspects of this approach. The aim of this review is to discuss the principles of the anterior approach, the outcomes and complications.

Preoperative Evaluation of Intramedullary Tibial Nail Measurements-A Review of the Literature and a New Technique Using Contralateral Radiographs and Digital Planning.

INTRODUCTION: An accurate selection of tibial nail and screws measurements is paramount in purpose to achieve proper tibial fracture reduction and fixation, avoid irritation of the soft-tissue envelope, and enable extraction of the nail in the future, if needed. To this date, many methods were suggested to determine the length and diameter of an intramedullary tibial nail, preoperatively and intraoperatively. Each method has its disadvantages, and most are lacking in accuracy. Digital aids are currently available for preoperative planning for many types of surgeries. METHODS: Retrospectively, 27 patients operated for diaphysial tibial fracture intramedullary nailing were selected. The contralateral leg was imaged using AP and lateral radiograph views. Six orthopaedic trauma surgeons used the TraumaCad program (Voyant Health) to plan the appropriate nail and distal locking screws measurements, while blinded from the actual hardware used in the operation. Later, they also conducted quality review regarding the operation carried out and suggested correction in measurements of the hardware. Intra-observer and inter-observer reliability was calculated. RESULTS: The inter-correlation coefficient for the planned nails was 0.97 and 0.84 (P < 0.001) in AP view for length and diameter, respectively, and similarly 0.98 and 0.86 (P < 0.001) in lateral view. The interclass correlation coefficient (ICC) for the locking screws length was 0.7 (P < 0.02) and 0.82 (P < 0.01) for the proximal and distal medio-lateral screws, respectively, and 0.9 (P < 0.001). The ICC between AP and lateral views was 0.98 for length and 0.96 for diameter (P < 0.001). The scores and corrections given by the examiners to the actual selected nail were ICC of 0.98 and 0.96 (P < 0.001) for length and diameter, respectively. The examiners suggested they would correct, post-factum, the length of the nail in average 28% and the diameter in average 30%. The average observer resulted in ICC of 0.94 and 0.91 (P < 0.001) in length and only 0.77 and 0.67 (P < 0.001) in diameter (AP and lateral views, respectively) when comparing the actual nail used and the post-factum plan. CONCLUSION: Preoperative planning of tibial fractures' nailing using imaging of the contralateral leg and a digital graphic planning program is an accurate and reliable method. It may serve to reduce errors, surgical time, and radiation dose in the operating room. This method could also be applied for surgical debriefing.

Phosphodiesterase 5 inhibition protects against increased intra-abdominal pressure-induced renal dysfunction in experimental congestive heart failure.

AIMS: Congestive heart failure (CHF) is associated with impaired renal function. Previously, we have demonstrated that rats with decompensated CHF exhibited exaggerated sensitivity to the adverse renal effects of increased increased intra-abdominal pressure (IAP) as compared with normal controls. This study tested whether phosphodiesterase 5 (PDE5) inhibition protects against the adverse renal effects of increased IAP in rats with CHF. METHODS AND RESULTS: Following baseline periods, rats with compensated and decompensated CHF induced by the placement of an aorto-caval fistula (ACF), rats with myocardial infarction (MI) induced by left anterior descending (LAD) artery ligation, and sham controls were subjected to consecutive IAPs: 7, 10, or 14 mmHg. Urine flow (V), Na(+) excretion (U(Na)V), glomerular filtration rate (GFR), and renal plasma flow (RPF) were determined. The effects of pre-treatment with tadalafil on the adverse renal effects of IAP were examined in rats with decompensated CHF and MI. Elevation of IAP to 10 and 14 mmHg produced linear reductions in these parameters. Basal renal function and haemodynamics were lower in CHF rats. Decompensated CHF rats and MI rats that were subjected to 10 and 14 mmHg exhibited exaggerated declines in V, U(Na)V, GFR, and RPF. In contrast, no adverse renal effects were observed in rats with compensated CHF subjected to IAP. Pre-treatment of decompensated CHF rats and MI rats with tadalafil ameliorated the adverse renal effects of high IAP. CONCLUSION: Decompensated CHF and MI rats are vulnerable to the adverse renal effects of IAP. Tadalafil abolishes IAP-induced renal dysfunction, supporting a therapeutic role for PDE5 inhibition in CHF associated with ascites.

Submuscular plating of femoral fractures in children: the importance of anatomic plate precontouring.

Despite many treatment options, the treatment of metaphyseal pediatric femoral fractures remains to be controversial. Fixation of most metaphyseal femoral fractures in older children is difficult to perform. Recently, bridging fixation of such fractures by submuscular plating has become popular. Plate precontouring as close as possible to anatomic bony structure is important, as the femur will subsequently reduce to the contour of the plate with screw placement. Our technique is using plates that are anatomically precontoured to a cadaver adolescent femur to ensure proper postoperative alignment. In this study we evaluate the effectiveness of submuscular plating performed in our institution using this technique, in 11 patients. All fractures united with good alignment. No major complication occurred. In conclusion, submuscular plating of adolescent femoral fractures with precontoured plates is an effective, predictable, and safe procedure.

Use of a new exsanguination tourniquet in internal fixation of distal radius fractures.

We describe our experience using a new device that results in a bloodless field in open repair of distal radius fractures. The device, an exsanguinating tourniquet (HemaClear model/40, OHK Medical Devices, Haifa, Israel), replaces the traditional methods of limb elevation, Esmarch bandaging, pneumatic tourniquet pressurizing and the associated components. HemaClear/40 is an elastic silicon ring with a tubular elastic sleeve rolled onto it. The device has attached straps that, when pulled, unroll the sleeve, rolling the ring mesially on the limb. The pressure exerted by rolling HemaClear/40 is supra-systolic thereby exsanguinating the limb and occluding the arterial inflow. Our experience in 49 patients demonstrated quick application, superior exsanguination and that the device could be placed on the forearm instead of the upper arm. No side effects or complications were noted. In our opinion, the fact that HemaClear/40 is a sterile, single-patient device makes it superior over the traditional technology.

Recurrent abdominal pain before and after appendectomy.

BACKGROUND: Patients with non-inflamed appendix have been reported to have had more hospitalizations and emotional disorders before and after the operation than patients with acute appendicitis. OBJECTIVES: To compare abdominal pain characteristics, as well as demographic and psychosocial data in children with histologically confirmed appendicitis compared to non-inflamed appendices. METHODS: Charts of children with suspected appendicitis who had undergone appendectomy were retrospectively reviewed for relevant clinical and laboratory data. The patients or their parents were then contacted by phone and were asked to respond to a detailed questionnaire on abdominal symptoms as well as demographic and psychosocial data. RESULTS: The study group comprised 156 children: 117 with histologically confirmed appendicitis and 39 with normal appendices. Eighty-two patients (53.2%) were located and interviewed: 62 (54%) with appendicitis and 20 (51%) with normal appendices. Of the 82 children, 16 reported recurrent episodes of abdominal pain before or after surgery: 11 (17.7%) in the appendicitis group and 5 (25%) in the normal appendix group. Only six patients fulfilled the formal criteria for the diagnosis of recurrent abdominal pain: 5 (8%) from the appendicitis group and 1 (5%) from the non-inflamed appendix group (not significant). In addition, no significant statistical differences were found between the groups regarding school performance, behavior and social interaction with peers. CONCLUSIONS: We could not demonstrate an increased incidence of recurrent abdominal pain, nor could we identify significant psychosocial morbidity in those children undergoing an appendectomy for a non-inflamed appendix.
