Multidisciplinary Treatment on a 69 years-old Male with Kidney Stone and Chronic Kidney Disease

Introduction Obstruction by kidney stones is one of the causes of chronic kidney disease (CKD). Out of all CKD cases, 10.3% are associated with obstruction due to kidney stones. Treatment of kidney stones can restore kidney function, but requires holistic and intense collaboration between urologists to treat the stones, nephrologist to monitor kidney function, and nutritionists to provide proper diet to prevent kidney stone reccurence Case Presentation A 69-year old male presented to the emergency departement with flank pain since 1 week ago. The patient complained of frequent flank pain since the last year. BOF radiological examination found staghorn stones in the right kidney, and ultrasonography revealed severe hydronephrosis of the right kidney. An impaired kidney function and decreased eGFR related to CKD were also found. The urologist performed bivalve nephrolithotomy on the right kidney. Afterwards, a histopathological examination was done to determine the stone material for further collaborative management with internist and nutritionist. After consultation with nutritionists regarding nutritional needs, monitoring from internist was done to monitor comorbidities and progression of CKD. Kidney function was evaluated after collaborative management and we found improvement on kidney function. Discussion In patients with CKD caused by obstruction due to kidney stones, it is necessary to treat the kidney stones first to relieve obstruction and restore kidney function. In this case the role of the internist is to control and recover kidney function after urologists have relieved the patient from urinary obstruction. Kidney stones that have been successfully removed are subjected to histopathological examination to determine its composition. After the composition were identified, consultation with a nutritionist is carried out to determine the right diet for the patient. With the right diet, prevention of stone reoccurrence is expected. Conclusion A history of kidney stones is associated with an increased risk of CKD. Multidisciplinary collaboration between urologists, nephrologist, and nutritionists helps lower the risk of stone recurrence and minimize the need for additional operative procedures through a focus on dietary and medical approaches and improved kidney function.

Ilizarov External Fixator Versus Orthofix LRS in Management of Femoral Osteomyelitis: A Propensity Score Matched Analysis.

Treatment of osteomyelitis (OM) is challenging. Ilizarov bone transport is a commonly used technique for management of OM. The recently introducedlimb reconstruction system (LRS) has been effectively used for management of OM. It was suggested to be easier in use and less invasive. The present retrospective study aimed to compare LRS and Ilizarov bone transport in management of femoral OM using a propensity score matched analysis. The present retrospective study included 80 consecutive patients with femoral OM. The studied patients were managed either using Ilizarov external fixator (n = 40) or Orthofix LRS (n = 40). The clinical outcome measurements included union time, limb length discrepancy, additional operative procedures, refracture and infection. Patients in the LRS group were exposed to significantly higher frequency of bone transport (30.0 versus 15.0%) and lower frequency of acute compression and lengthening (10.0 versus 32.5%). Patients in Ilizarov group had significantly higher frequency of tobramycin pellets as compared to their counterparts. The studied groups were comparable regarding the operative complications including pin-tract infection, non-union at docking site and refracture. Patients in the Ilizarov had significantly shorter time to union (8.2 ± 3.2 versus 11.0 ± 5.6 months, p = 0.012). No statistically significant differences were found between the studied groups regarding the quality-of-life domains. Use of Ilizarov external fixator and Orthofix LRS devices proved to be effective and reliable. Their influences on patients' quality appear to be comparable.

Republication of "Treatment of Hallux Valgus Deformity Using a Suture Button Device: A Preliminary Report".

Hallux valgus (HV) is commonly treated with proximal or distal first metatarsal osteotomy. Despite good correction, these procedures have inherent risks such as malunion, nonunion, metatarsal shortening, loss of fixation, and avascular necrosis. Suture button fixation has been used for HV treatment. It avoids the risks of corrective osteotomies while maintaining reduction of the intermetatarsal angle (IMA). The goal of this study was to assess the radiographic and functional outcomes of patients undergoing HV correction with a distal soft tissue procedure and proximal suture button fixation. The authors retrospectively reviewed the charts and radiographs of 22 patients who had undergone HV correction using a distal soft tissue correction and proximal fixation with a miniature suture button device (Mini TightRope; Arthrex, Inc, Naples, FL). Mean follow-up was 27.7 months. The IMA, hallux valgus angle (HVA), and sesamoid station were measured on radiographs obtained preoperatively as well as in the immediate postoperative period and at final follow-up. Preoperative and postoperative Short Form-36 (SF-36) and Foot and Ankle Ability Measure (FAAM) scores were collected. Postoperative complications, and any additional operative procedures performed were also recorded. The mean preoperative IMA and HVA were 16.9 and 32.6 degrees, respectively. The mean immediate postoperative IMA was 5.2 degrees (P < .0001) and the mean HVA was 9.8 degrees (P < .0001). At final follow-up, the mean IMA was 8.2 degrees (P < .0001) and the mean HVA was 16.7 degrees (P < .0001). The average change in HVA from preoperative to final follow-up was 16.0 degrees and the average change in IMA from preoperative to final follow-up was 8.6 degrees (P < .0001). Sesamoid station assessment at the 2-week follow-up showed that 22 patients (100%) were in the normal position group; at final follow-up, 17 patients (77%) had normal position and 5 patients (23%) had displaced position. Although there were no clinically symptomatic recurrences, asymptomatic radiographic recurrence was noted in 5 patients (23%) who had a final HVA >20 degrees. All components of the FAAM and the SF-36 showed improvement from preoperative to final follow-up, although these changes were not statistically significant. Three patients experienced complications, including an intraoperative second metatarsal fracture, a postoperative second metatarsal stress fracture, and a postoperative deep vein thrombosis. The use of a distal soft tissue procedure in conjunction with proximal suture button fixation is a safe and effective procedure for treating symptomatic HV deformity. Our results show that this technique can correct the IMA, HVA, and sesamoid station without the need for osteotomy. Level IV.

Functional outcomes and health-related quality of life after reconstruction of segmental bone loss in femur and tibia using the induced membrane technique

IntroductionThe induced membrane technique (IMT), frequently called Masquelet technique, is an operative, two-staged technique for treatment of segmental bone loss. Previous studies mainly focused on radiological outcome parameters and complication rates, while functional outcomes and health-related quality of life after the IMT were sparsely reported.Materials and methodsRetrospective study containing of a chart review as well as a clinical and radiological follow-up examination of all patients treated with the IMT at a single institution. The clinical outcomes were evaluated using the Lower Extremity Functional Scale (LEFS), the Short-Form-36 (SF-36) and the visual analog scale (VAS) for pain. The radiographic evaluation contained of standard anteroposterior and lateral, as well as hip-knee-ankle (HKA) radiographs.ResultsSeventeen patients were included in the study. All had suffered high-energy trauma and sustained additional injuries. Ten bone defects were localized in the femur and seven in the tibia. Ten patients underwent additional operative procedures after IMT stage 2, among them three patients who contracted a postoperative deep infection. The median LEFS was 59 (15–80), and the SF-36 physical component summary (PCS) and mental component summary (MCS) were 41.3 (24.0–56.1) and 56.3 (13.5–66.2), respectively. The median length of the bone defect was 9 (3–15) cm. In 11 patients, union was obtained directly after IMT stage 2. Bone resorption was observed in two patients. At follow-up, 16 of the 17 bone defects had healed. The median follow-up was 59 months (13–177).ConclusionOur results show a high occurrence of complications after IMT stage 2 in segmental bone defects of femur and tibia requiring additional operative procedures. However, fair functional outcomes as well as a good union rate were observed at follow-up.

Mono-Lateral External Fixation for Treatment of Femoral Osteomyelitis.

Maintenance of stability using external fixation devices is an important principle to ensure successful treatment of osteomyelitis (OM). In this study, we report our experience with femoral OM treated with acute compression and bone transport using the Orthofix limb reconstruction system (LRS). This prospective study included 30 consecutive patients with femoral OM. LRS insertion and corticotomy were done according to the standard technique. Radiographic evaluation was performed every 2 weeks during the distraction phase and every 2-4 weeks during the consolidation phase. The clinical outcome measurements included union time, limb length discrepancy, additional operative procedures, refracture and infection. The present study included 30 patients with femoral OM. They comprised 27 males (90.0%) and 3 females (10.0%) with an age of 28.1 ± 15.6 years. All, except one, achieved union with a mean union time of 8.6 months (range 4-20 months). The mean union time for acute compression was 7.6 months (range 4-20 months) while for patients with bone transport it was 14.5 months (range 12-18 months). The mean limb length discrepancy was 1.8 cm (range 0-4 cm). At the end of the follow=up, two patients were not able to ambulate without support; one due to non-union and one due to paraplegia. The present study identified treatment of femoral OM using LRS as a feasible and effective technique with good outcomes. Reported complications could be adequately managed in most cases.

Does Synchronous Liver Intervention Increase Risk of Venous Thromboembolism in Patients with Metastatic Small-Bowel and Pancreatic Neuroendocrine Tumors?

INTRODUCTION: Previous literature suggests a higher incidence of venous thromboembolism (VTE) in patients with pancreatic neuroendocrine tumor (PNET) but no other gastrointestinal NET. In this study, we analyze the incidence of VTE in patients with metastatic small-bowel neuroendocrine tumors (SBNETs) and PNET undergoing synchronous liver procedures to determine whether these patients require extended VTE prophylaxis. METHODS: The American College of Surgeons NSQIP database was queried from 2008 to 2019 for patients undergoing operation for SBNET, PNET, benign small bowel, and pancreatic pathology. Patients with SBNET and PNET were stratified by additional operative procedures for liver metastasis (LM). The rate of 30-day postoperative VTE (pulmonary embolism [PE] and/or deep vein thrombosis [DVT]) was compared. Pearson’s chi-square and ANOVA tests were used for analysis. RESULTS: A total of 89,054 patients met inclusion criteria (63,396 benign small bowel, 3,073 SBNET, including 918 with LM, 18,724 benign pancreas, 3,861 PNET including 949 with LM). There was no statistically significant difference in the rate of VTE in patients with small-bowel disease with or without LM. Patients in the PNET with LM group had a significantly higher rate of PE but not DVT than those undergoing pancreatic operation for benign pathology (2.4% vs 1.1%; p < 0.001). Total operation time (odds ratio [OR] 1.002; p = 0.002), length of hospital stay (OR 1.027; p < 0.001), and preoperative dialysis (OR 3.779; p = 0.004) were independently associated with VTE. However, synchronous liver intervention was not an independent factor associated with VTE or PE in patients with PNET (Table 1). Table 1. - Rates of DVT and PE in Patients with PNETs and SBNETs Undergoing Synchronous Liver Procedures Group Total Rate of DVT Rate of PE Benign small-bowel procedures 63,396 987 (1.6%) 398 (0.6%) Procedures for SBNETs 2,155 26 (1.2%) 11 (0.5%) SBNETs with synchronous liver procedures 918 12 (1.3%) 9 (1.0%) Benign pancreas procedures 18,724 400 (2.1%) 203 (1.1%) Procedures for PNETs 2,912 59 (2.0%) 44 (1.5%) PNETs with synchronous liver procedures 949 18 (1.9%) 23 (2.4%) CONCLUSION: Synchronous liver intervention does not increase the risk of VTE in patients with metastatic SBNET or PNET.

A New 3-Stage Approach for Reoperative Hypospadias.

Most hypospadias patients undergo 1 surgical procedure and go on to live normal lives. However, there is a small subset of patients who have remaining functional complications after their repair. Patients presenting with diffuse scarring of the urethral plate and a shortage of penile skin for closure are referred to as "hypospadias cripples." We present our experience using tissue expanders in the treatment of reoperative hypospadias with skin deficiency. We retrospectively reviewed hospital records from 2009 to 2019. Five hypospadias cripple patients were encountered. A multidisciplinary team involving plastic surgery and pediatric urology collaborated a 3-stage reconstructive plan:Stage 1-Scar excision and buccal mucosal graft harvestStage 2-Dorsal tissue expander placementStage 3-Tissue expander explantation, creation of neourethra, and skin closure. Successful skin closures were achieved in all patients. There were no cases of expander explanation. Average time between tissue expander placement and final reconstruction ranged from 3 to 4 months. Complications included 2 cases of penile cellulitis, 1 with an associated abscess, and 2 limited urethrocutaneous fistulas, which were addressed with an additional operative procedure. The 3-stage approach is advantageous in treating hypospadias cripple patients. This population can benefit greatly from tissue expander placement after buccal result with an acceptable complication rate. Using a multidisciplinary approach is beneficial in treating these complex patients.

Bilayer wound matrix-based cutaneous scalp reconstruction: A multidisciplinary case control analysis of factors associated with reconstructive success and failure

Scalp wounds pose reconstructive challenges due to the lack of skin elasticity, potential for compromised adjacent tissue, and desire for the restoration of esthetic contour. Bilayer Wound Matrix (BWM) has been successfully employed as a treatment modality for complex, full-thickness wounds of the scalp. We aimed to highlight risk factors for BWM success and failure in complex wounds of the scalp. A retrospective case-control study was performed from 2012 to 2019 of adult subjects who presented to plastic or dermatological surgery with complex scalp defects with or without exposed calvarium, who underwent staged reconstruction with BWM and split-thickness skin grafting or secondary intention. Success was defined as complete wound re-epithelialization within 90-day follow-up without additional operative procedures for wound coverage. Demographics, comorbidities, treatment history, wound characteristics, and clinical course were analyzed and correlated with reconstructive outcomes. In total, 127 subjects were identified for inclusion, with mean age 74.6 ± 12.2 years, defect area 80.2 ± 89.4 cm2, and wound age 10.0 ± 65.4 days. Successful wound reconstruction occurred in 107 (84%) subjects. Postoperative wound infections were an independent predictor of BWM failure at 90 days (Odds Ratio: 6.4, 95% Confidence Interval: 1.5 - 26.7, and p<0.012). Additionally, subjects who underwent preoperative radiation were more likely to suffer from reconstructive failure (p<0.040) as well as those who require postoperative inpatient admission (p<0.034). BWM represents a reliable and efficacious modality in the treatment of complex scalp wounds. Patient comorbidities may not heavily influence the success of BWM to establish adequate wound coverage; however, preoperative radiation and postoperative wound infection may often lead to reconstructive failure.

Do Poller screws effect union in tibial shaft fractures treated with intramedullary nailing?

IntroductionTibial shaft fractures are a commonly encountered challenge presented to orthopaedic trauma surgeons. Intramedullary nailing (IMN) is often the treatment of choice and whilst effective, complications of delayed and/or non-union can cause significant morbidity and necessitate additional operative procedures. The use of Poller screws during IMN are a recognised way of aiding fracture reduction, however the clinical benefits of this are debated. This study evaluated the outcome of tibial shaft fractures treated with IMN with or without the addition of Poller screws. MethodsRetrospective cohort study of all patients undergoing IMN following tibial shaft fractures over a 5-year period. 154 operated tibial shaft fractures were identified, with patients divided into 3 groups - Group 1: IM nailing alone, Group 2: IMN + 1 conventional Poller screw, or Group 3: IMN + 2 Poller screws placed Epicentrically across the fracture site. Data collected included demographics, length of stay, fracture type, position and AO classification grade, operative time, and operating surgeons' grade. Primary outcome measure was the incidence of delayed and/or non-union. Secondary outcomes were differences in rates of infection and additional orthopaedic procedures between the 3 groups. ResultsOverall 139/154 fractures (90.3%) achieved a timely union. There was a statistically significant difference (p = 0.05) in fracture union between the 3 groups, with 75/88 fractures healing in group 1 (IMN alone) compared to 44/46 in Group 2 (IMN + 1 Poller screw) and 20/20 in group 3 (IMN + 2 Poller screws). There was no statistical difference in the incidence of superficial infection, (p = 0.95) additional procedures (p = 0.23) or deep infection (p = 0.65) between the 3 groups. ConclusionThe addition of Poller screws appear to be a safe and effective adjunct in the treatment of tibial shaft fractures via IMN. Further prospective randomised trials are needed to fully elucidate both the role and potential benefits of Poller screw augmentation in acute lower limb fracture management.

Difficult laparoscopic cholecystectomy and preoperative predictive factors

Laparoscopic cholecystectomy (LC) is the standard technique for treatment of gallbladder disease. In case of acute cholecystitis we can identify preoperative factors associated with an increased risk of conversion and intraoperative complications. The aim of our study was to detect preoperative laboratory and radiological findings predictive of difficult LC with potential advantages for both the surgeons and patients in terms of options for management. We designed a retrospective case–control study to compare preoperative predictive factors of difficult LC in patients treated in emergency setting between January 2015 and December 2019. We included in the difficult LC group the surgeries with operative time > 2 h, need for conversion to open, significant bleeding and/or use of synthetic hemostats, vascular and/or biliary injuries and additional operative procedures. We collected 86 patients with inclusion criteria and difficult LC. In the control group, we selected 86 patients with inclusion criteria, but with no operative signs of difficult LC. The analysis of the collected data showed that there was a statistically significant association between WBC count and fibrinogen level and difficult LC. No association were seen with ALP, ALT and bilirubin values. Regarding radiological findings significant differences were noted among the two groups for irregular or absent wall, pericholecystic fluid, fat hyperdensity, thickening of wall > 4 mm and hydrops. The preoperative identification of difficult laparoscopic cholecystectomy provides an important advantage not only for the surgeon who has to perform the surgery, but also for the organization of the operating block and technical resources. In patients with clinical and laboratory parameters of acute cholecystitis, therefore, it would be advisable to carry out a preoperative abdominal CT scan with evaluation of features that can be easily assessed also by the surgeon.

Pediatric osteoarticular infection: trend in surgically treated patients and association of methicillin-resistant Staphylococcus aureus with requirement of secondary procedures.

Acute pediatric osteoarticular infection demonstrates variability in both presentation and response to treatment. Many respond to antibiotics ± single operation, while some require multiple surgeries. Currently, it is difficult to predict who may require additional procedures. Infections due to methicillin-resistant Staphylococcus aureus (MRSA) have been associated with more complications. The purpose of this study is to determine MRSA trends and degree of association with the occurrence of multiple procedures. We performed a retrospective analysis of surgically treated pediatric (1 month-18 years) patients for acute osteomyelitis and septic arthritis at a tertiary children's hospital from 2003-2017. The cohort was divided into single-procedure and multiple-procedure groups. A total of 753 patients were studied with a mean age of 7.05 years (2.4 months-17.9 years). We identified 645/753 (85.6%) patients who were treated with a single-procedure and 108/753 (14.4%) patients who required multiple- procedures. The lower extremity (hip, knee, tibia, and femur) was most commonly involved. The epidemiologic trend runs almost parallel between two groups with a peak in 2009. The odds ratio for multiple-procedures was 2.0 [95% confidence interval (CI), 1.2-3.1; P = 0.002] with dual infection (osteomyelitis + septic arthritis), 2.6 (95% CI, 1.6-4.4; P = 0.001) with high-risk conditions and 4.6 (95% CI, 3.0-7.1; P < 0.001) if MRSA was present. MRSA significantly predicts the requirement of additional operative procedures for the treatment of osteoarticular infections in children. Besides clinical deterioration and other markers, the presence of MRSA can be a considerable indicator for a planned secondary-procedure. Level III retrospective cohort study.

Adverse Events Related to Polyvinyl Alcohol Hydrogel Hemiarthroplasty of 1st Metatarsal: An Analysis of Reports to the United States Food and Drug Administration

Category:Midfoot/ForefootIntroduction/Purpose:Polyvinyl Alcohol Hydrogel (PAH) hemiarthroplasty has gained popularity in the operative management of symptomatic hallux rigidus since its introduction to the US in July 2016. Despite encouraging initial results, any implant has the potential for complications that may not become apparent until it is in widespread use. Also, the series of publications supporting the effectiveness of PAH have come from a limited group of institutions and surgeons which creates an opportunity for observational bias. Other complications or unsatisfactory outcomes may be under-reported, such as those experienced in community centers due to the challenges in publishing lower volume work. In order to look at a broader range of potential complications, we reviewed the United States Food and Drug Administration’s (FDA) database and compared with published literature.Methods:The Manufacturer and User Facility Device Experience (MAUDE) database of the US Food and Drug Administration (FDA) was retrospectively reviewed between July 2016 and October 2019 using the assigned product code: PNW for the PAH implant. All the reported adverse events, implant-related complications, and secondary procedures were analyzed.Results:A total of 49 events have been reported to this voluntary database over the past 3 years while over 22,000 Cartiva devices have been implanted. Implant subsidence was the most common with 16 reported instances. Fragmentation of the device was observed in nine and four reports were related to infection in which two were deep infections needing antibiotic spacers.Bone erosion managed by grafting was documented in three reports and foreign body reaction was noted in one. Persistent pain and swelling were common presentations. Thirty-five of 49 reported events required additional operative procedures performed at a mean interval of 4.75 months following the index procedure while four more were awaiting further surgery. Conversion to fusion was the most common procedure, featured in 10 reports.Conclusion::The analysis of the MAUDE database disclosed certain device-related dysfunctions that have been under-reported in the published literature. Also, complications such as fragmentation, bone erosion and foreign body reaction have not been previously described. Awareness of these details will assist in decision-making and quality control. Due to the voluntary nature of reporting, the true incidence of each complication is unknown with the above data representing a baseline. Nonetheless, the MAUDE database serves as an illuminating source of information which would further be strengthened by a more robust and mandatory reporting of device-related complications.

Complications Following Transosseous Repair of Zone I Flexor Tendon Injuries

Multiple techniques are described for repair of zone I flexor tendon injuries, many of which are fraught with complications. This study evaluated the clinical complications after a transosseous repair technique. A retrospective review of a single institutional database identified all zone I flexor digitorum profundus (FDP) injuries repaired using a transosseous technique. In this technique, 2 nonabsorbable sutures were passed from volar to dorsal through transosseous tunnels and tied dorsally over the distal phalanx proximal to the germinal matrix. Demographics, injury characteristics, operative details, and complications were reviewed. Eight patients met the inclusion criteria. Average age was 31 years (range, 15-66 years) and all patients were male. Eight fingers were included: ring (4), small (3), and middle (1). Seven injuries were closed and one was open. Average time between injury and surgery was 13 days (range, 4-34 days). Five patients experienced complications, including osteomyelitis, chronic draining granuloma, and abnormal nail growth. Three patients required an additional operative procedure for management of complications. Transosseous repair of zone I flexor digitorum profundus injuries with a buried dorsal suture is associated with a high rate of clinical complications. Therapeutic V.

Suture Button Technique for Tibialis Anterior Tendon Transfer for the Treatment of Residual Clubfoot.

Background:The Ponseti method has revolutionized the treatment of idiopathic clubfoot, but recurrence remains problematic. Dynamic supination is a common cause of recurrence, and the standard treatment is tibialis anterior tendon transfer using an external button. Although safe and effective, the placement of the button on the sole creates a pressure point, which can lead to skin ulceration. In our institution, a suture button has been used for the tibialis anterior tendon transfer and we report our results here.Methods:Two senior authors’ case logs were retrospectively reviewed to identify 23 patients (34 feet) for tibialis anterior tendon transfer using a suture button. Complications and additional operative procedures were assessed by reviewing operative notes, follow-up visit clinic notes, and radiographs. The mean age of the patients was 6 years 2 months (SD 40 months) and the average follow-up duration was 67.1 weeks (SD 72 weeks).Results:There were 5 complications (14.7%). Recurrence occurred bilaterally in 1 patient (5.9%) but did not require reoperation. Other complications included a cast-related pressure sore (2.9%) and an infection (2.9%) requiring irrigation with debridement along with hardware removal.Conclusions:Tibialis anterior tendon transfer using a suture button was a safe procedure with theoretical advantage of providing stronger fixation and reducing the risk of skin pressure necrosis compared to the standard external button technique. We believe a suture button could allow earlier rehabilitation and may afford stronger ankle eversion. Prospective studies are required to compare the differences in functional outcomes between the procedures.Level of Evidence:Level IV, case series, therapeutic study.

Isolated Medial Patellofemoral Ligament Reconstruction Can Be an Effective Procedure in Patellofemoral Instability with Risk Factors.

Patellofemoral instability is a severe problem in young and active patients. This pathology is influenced by ligamentous, bony, and neuromuscular parameters. The reconstruction of the medial patellofemoral ligament (MPFL) evolved to a primary procedure, but combined procedures were more frequently performed in the past years. However, additional operative procedures are associated with increased morbidity and no absolute indication can be identified in the literature. This study is intended to clarify whether addressing only ligamentous influence factors (MPFL) in chronic patellofemoral instability is sufficient to produce good clinical outcomes, or whether other risk factors influence the results negatively and should also be treated at some point. In 52 patients with chronic patellofemoral instability patellar height according to Caton-Deschamps, trochlear dysplasia according to Dejour, the leg axis, the femoral antetorsion, tibial tubercle (TT)-trochlear groove, and TT-posterior cruciate ligament distance were evaluated. All patients were treated with isolated MPFL reconstruction. After a minimum follow-up period of 24 months (24-36 months), the clinical outcome results were calculated using the scoring system according to Lysholm and Tegner. Correlation between clinical outcome scores and anatomic risk factors were calculated. The analysis was performed using a standard statistical software package (JMP version 12, SAS Institute, Cary, NC). The average postoperative Lysholm score increased significantly from 57.23 ± 19.9 to 85.9 ± 17.2 points (p < 0.0001) after isolated MPFL reconstruction. Moreover, the Tegner and Lysholm scores significantly improved both in patients without and with different risk factors postoperative. There were no significant differences in the outcome sores between the groups. Even the degree of trochlear dysplasia (types I-III) did not influence the results. Finally, there was no significant correlation found between all collected risk factors and the postoperative outcome scores. Isolated MPFL reconstruction can be an effective procedure in patients with patellofemoral instability and mild to moderate risk factors.

Obesity in Adolescents and Youth: The Case for and against Bariatric Surgery

Ankle fusion by Ilizarov external fixator

Introduction Arthrodesis is a salvage procedure for patients with a destroyed, painful ankle joint to restore pain-free ambulation. The paper aimed to evaluate the results of ankle arthrodesis using the Ilizarov external fixator to treat end-stage tibiotalar arthritis. Patients and methods This retrospective study included 20 patients who had been treated with ankle fusion by Ilizarov fixator performed from December 2007 to January 2014. Their mean age was 44.95 years. Eight patients were females. The underlying pathology was septic ankle destruction, post-traumatic osteoarthritis, and rheumatoid arthritis. Avascular necrosis of talus was present in three cases. Seventeen patients had previous surgical procedures with a mean of 2.15 surgeries. Five patients had a failed previous arthrodesis. Six patients had associated equinus deformity. The mean preoperative American Orthopaedic Foot and Ankle Society Ankle-Hind foot score was 26. Results The mean follow-up period was 28.15 months. The mean external fixation period was 15.75 weeks. Sound fusion was achieved in all patients without additional operative procedures. Infection was controlled in all septic ankles. Pin-tract infections were observed in seven cases. In three cases, wires or half-pins needed to be removed. One ankle was fused in mild varus. One patient reported moderate daily diffuse pain. The mean postoperative American Orthopaedic Foot and Ankle Society Ankle-Hind foot score was 75.45. Patients reported functional satisfaction with the results. Conclusions The use of the Ilizarov external fixator provides a successful salvage method that offers solid bony fusion, optimal alignment, and eradication of infection in complex ankle pathology or failed previous arthrodesis.

Hospital readmissions in paediatric trauma patients: A 10-year Australian review.

Readmission of paediatric trauma patients is associated with increased hospital length of stay, additional operative procedures and significant costs to the health-care system. The rates and causes of readmission of paediatric trauma patients are not well reported outside of the USA or single centres. This nation-wide study is the first in Australia to examine the readmission rates, costs and characteristics of Australian paediatric trauma patients. This was a retrospective examination of linked hospitalisation and mortality data for injured children aged 16 or younger from 1 July 2001 to 30 June 2012, readmitted to hospital within 28 days of discharge. Data including injury severity, nature of injury, episodes of care and costs were extracted from hospitalisation data. There were 37 603 injury children aged ≤16 years readmitted to hospital within 28 days during the 10-year period, a readmission rate of 5.5%. The most common principal injury requiring readmission was fracture (52.6%) and burns (19.3%). A total of 66% of all patients had a readmission diagnosis of injury, complication of their initial injury or complication of surgical and medical care; 30% were readmitted for a specific procedure or follow-up care. The total cost of readmissions was AU$108 million. Hospital readmission rates of paediatric trauma patients in Australia are due to injury or a complication of injury and are associated with significant costs. Early identification of at-risk patients and the prevention of complications are needed to prevent the ongoing burden of readmission.

Permacol Collagen Paste Injection for Treatment of Complex Cryptoglandular Anal Fistulas: An Observational Cohort Study With a 2-Year Follow-up.

Permacol paste injection is a novel treatment approach for complex cryptoglandular anal fistulas. This study was performed to evaluate the long-term clinical outcomes of treatment with Permacol paste for complex cryptoglandular fistulas. Patients with primary or recurrent complex cryptoglandular anal fistulas treated with Permacol paste from 2014 to 2016 were retrospectively analyzed. A total of 46 patients (median age, 41.3 years; 21 female) underwent Permacol paste injection; 20 patients (43%) had previously undergone failed fistula surgery. The patients had experienced anal fistula-related symptoms for a median of 10 weeks (range, 3-50 weeks). All patients had a draining seton in situ for a median of 10 weeks (range, 4-46 weeks). The median follow-up time was 24 months (range, 1-25 months). At the 1-month follow-up, 2 patients had paste extrusion and 2 had anal abscesses. The mean preoperative Continence Grading Scale score was 1.10 ± 1.40, and that at 3 months postoperatively was 1.13 ± 1.39 ( P = .322). There was a significant difference in the preoperative and the 1- and 3-month postoperative pain scores ( P < .001). At the 24-month follow-up, the healing rate was 50% (n = 23). A total of 19 patients (41%) with a recurrent fistula after failed Permacol paste injection required additional operative procedures. The satisfaction rate at the 2-year follow-up was 65%. Permacol paste injection is minimally invasive and technically easy to perform. It can be considered as a viable and reasonable option for the treatment of complex cryptoglandular anal fistulas in patients with fecal continence disorders.
