RESUMO

PURPOSE: To investigate the effect of suprascapular nerve release in arthroscopic rotator cuff repair surgery. METHODS: This systematic review was performed to include randomized controlled trials (RCTs) and non-RCTs that compared the outcomes of patients who did and did not receive suprascapular nerve release (SSNR) during arthroscopic rotator cuff repair surgery. MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched for relevant studies. Methodological Index for Non-randomized Studies (MINORS) was used for cohort study assessment. The Cochrane risk of bias assessment tool (version 1.0) was used to assess the risk of bias in randomized trials. The primary outcomes were pain and shoulder function. The secondary outcome was the re-tear rate. RESULTS: Two RCTs and three non-RCTs with a total of 187 patients (90 patients received SSNR and 97 patients did not receive SSNR) were included in this systematic review. The meta-analysis revealed that the SSNR group did not had a more pain reduction, assessed by visual analogue scale, compared to the non-SSNR group. Also, the SSNR group did not have a significantly more improvement in the UCLA score, compared to the non-SSNR group. In addition, there was no significant difference between the two groups in terms of Constant score and re-tear rate. CONCLUSIONS: The result of this study showed that additional suprascapular nerve release did not provide additional benefit in arthroscopic rotator cuff repair surgery. Routine arthroscopic SSNR is not recommended when treating patients with rotator cuff tear. LEVEL OF EVIDENCE: Level III.

RESUMO

BACKGROUND: This review was conducted to compare the efficacy of suprapatellar (SP) and infrapatellar (IP) approaches for treating distal tibial fractures with intramedullary nailing. METHOD: This systematic review included studies comparing the outcomes of patients receiving nailing for distal tibial fractures using the SP and IP approaches. We searched the Cochrane CENTRAL, MEDLINE and Embase databases for relevant studies till 18th Sep. 2022. We used the Newcastle Ottawa Scale to assess study quality and a random-effects meta-analysis to synthesize the outcomes. We used the mean difference (MD) or standardized mean difference (SMD) with the 95% confidence interval (CI) for continuous data and the odds ratio (OR) with the 95% CI for dichotomous data. RESULTS: Four studies with 586 patients (302 in the SP group and 284 in the IP group) were included in this systematic review. The SP group may have had little or no difference in pain and slightly better knee function (MD 3.90 points, 95% CI 0.83 to 5.36) and better ankle function (MD: 8.25 points, 95% CI 3.35 to 13.15) than the IP group 12 months after surgery. Furthermore, compared to the IP group, the SP group had a lower risk of malalignment (OR: 0.22, 95% CI 0.06 to 0.75; number needed to treat (NNT): 6), a lower risk for open reduction (OR: 0.58, 95% CI 0.35 to 0.97; NNT: 16) and a shorter surgical time (MD: - 15.14 min, 95% CI - 21.28 to - 9.00). CONCLUSIONS: With more advantages, the suprapatellar approach may be the preferred nailing technique over the infrapatellar approach when treating distal tibial fractures. LEVEL OF EVIDENCE: Level III, systematic review of non-randomized studies.

RESUMO

Shoulder arthroscopy is a mature and widely used treatment to deal with various shoulder disorders. It enables faster recovery and decreases postoperative complications. However, some complications related to shoulder arthroscopy cannot be neglected because they could be life threatening. We presented three cases of various clinical manifestations of pneumothorax after shoulder arthroscopy. The first case was a 65-year-old female who underwent arthroscopic rotator cuff repair under general anesthesia and interscalene nerve block in the beach-chair position. The second case was a 58-year-old male undergoing arthroscopic rotator cuff repair and reduction in glenoid fracture under general anesthesia in the lateral decubitus position. The third case was a 62-year-old man receiving arthroscopic rotator cuff repair under general anesthesia in the lateral decubitus position. Each case's operation time was 90, 240, and 270 min. The pressure of the irrigation pumping system was 30, 50, and 70 mmHg, respectively. The second and third cases did not undergo interscalene nerve block. Although the incidence of pneumothorax following shoulder surgery and interscalene nerve block was only 0.2%, it is one of the most life-threatening complications following shoulder arthroscopy. In these cases, multifactorial factors, including patient positioning, interscalene nerve block, long surgical time, size of rotator cuff tears, and the pressure of the irrigation and suction system, can be attributed to the occurrence of pneumothorax. It is crucial to fully comprehend the diagnosis and management of pneumothorax to reduce the risk for patients receiving shoulder arthroscopy.

RESUMO

STUDY OBJECTIVE: Necrotizing fasciitis (NF) is an uncommon life-threatening necrotizing skin and soft tissue infection. Bullae are special skin manifestations of NF. This study was conducted to analyze the differences between different types of bullae of limbs with NF for providing the information to emergency treatment. METHODS: From April 2015 to August 2018, patients were initially enrolled based on surgical confirmation of limbs with NF. According to the presence of different bullae types, patients were divided into no bullae group (Group N), serous-filled bullae group (Group S), and hemorrhagic bullae group (Group H). Data such as demographics, clinical outcomes, microbiological results, presenting symptoms/signs, and laboratory findings were compared among these groups. RESULTS: In total, 187 patients were collected, with 111 (59.4%) patients in Group N, 35 (18.7%) in Group S, and 41 (21.9%) in Group H. Group H had the highest incidence of amputation, required intensive care unit care, and most patients infected with Vibrio species. In Group N, more patients were infected with Staphylococcus spp. than Group H. In Group S, more patients were infected with ß-hemolytic Streptococcus than Group H. Patients with bacteremia, shock, skin necrosis, anemia, and longer prothrombin time constituted higher proportions in Group H and S than in Group N. CONCLUSIONS: In southern Taiwan, patients with NF accompanied by hemorrhagic bullae appear to have more bacteremia, Vibrio infection, septic shock, and risk for amputation. If the physicians at the emergency department can detect for the early signs of NF as soon as possible, and more patient's life and limbs may be saved.

RESUMO

BACKGROUND: Vibrio vulnificus has been reported as the leading causative pathogen of necrotizing fasciitis (NF) and related fatality in the coastal area. Necrotizing fasciitis caused by methicillin-resistant Staphylococcus aureus (MRSA) and V. vulnificus have high mortality rates. The purpose of this prospective study was to clarify the clinical characteristics between death and survival NF patients, to investigate bacteriologic profile and mortality of NF patients, and to compare risk indicators of MRSA and V. vulnificus NF patients. METHODS: This prospective study was conducted in 184 consecutive NF patients over a period of three years in a tertiary coastal hospital. Differences in mortality, laboratory findings, microbiology and clinical outcomes were compared between the death and survival groups, and the V. vulnificus and MRSA subgroups. RESULTS: Twenty patients died, resulting in a mortality rate of 10.9%, and there were 108 patients with a monomicrobial infection (58.7%). The death group had a significantly higher incidence of shock at emergency room and bacteremia than did the survival group. Vibrio species (40 cases) and S. aureus (31 cases) were the two major pathogens. Significant differences with respect to hepatic dysfunction, shock, the event with seawater or seafood contact, bacteremia, C-reactive protein, mean platelet counts, and the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score were observes between V. vulnificus and MRSA groups. CONCLUSIONS: NF patients with both hepatic dysfunction and diabetes mellitus, bacteremia and shock have significantly higher mortality. We should be aware of the increasing incidence of monomicrobial NF and higher mortality rates of Gram-negative pathogens in the warm coastal area. LRINEC score is not a suitable diagnostic indicator for V. vulnificus NF, which is more rapidly progressive and fulminant than MRSA NF. NF needed team works by early suspicion, immediate surgical intervention and aggressive care, which can successfully decrease mortality.

RESUMO

Periprosthetic joint infections (PJIs) caused by Staphylococcus aureus infection are difficult to treat due to antibiotic resistance. It is known that the biofilms from methicillin-resistant S. aureus (MRSA) promote expansion of myeloid-derived suppressor cells (MDSCs) to suppress T-cell proliferation and benefit bacterial infections. This study finds that GMI, a fungal immunomodulatory peptide isolated from Ganoderma microsporum, suppresses MDSC expansion to promote the proliferation of cytotoxic T cells. The enhancement is likely attributed to increased expression of IL-6 and TNF-α and reduction in ROS expression. Similar beneficial effects of GMI on the suppression of MDSC expansion and IL-6 expression are also observed in the whole blood and reduces the accumulation of MDSCs in the infected bone region in a mouse PJI infection model. This study shows that GMI is potentially useful for treating S. aureus-induced PJIs.

RESUMO

BACKGROUND & AIMS: There is controversy over the best therapeutic approach for T1 colorectal cancer. We performed a systematic review and meta-analysis of long-term outcomes of endoscopic resection (ER) vs those of primary or additional surgery. METHODS: We performed a systematic review of the PubMed, Embase, and Cochrane databases through October 2019 for studies that reported outcomes (overall survival, disease-specific survival, recurrence-free survival at 5 years, recurrence, and metastasis) of ER vs surgery in patients with colorectal neoplasms. Hazard ratios (HR) were calculated based on time to events. RESULTS: In total, 17 published studies with 19,979 patients were included. The median follow-up time among the studies was 36 months. The meta-analysis found no significant differences between primary ER and primary surgery in overall survival (79.6% vs 82.1%, HR, 1.10; 95% CI, 0.84-1.45), recurrence-free survival (96.0% vs 96.7%, HR, 1.28; 95% CI, 0.87-1.88), or disease-specific survival (94.8% vs 96.5%; HR, 1.09; 95% CI, 0.67-1.78). Additional surgery and primary surgery did not produce significant differences in recurrence-free survival (HR, 1.27; 95% CI, 0.85-1.89). A significantly lower proportion of patients who underwent primary ER had procedure-related adverse events (2.3%) than patients who underwent primary surgery (10.9%) (P < .001). Lymphovascular invasion and rectal cancer, but not depth of submucosal invasion, were independently associated with recurrence for all T1 colorectal cancers. CONCLUSIONS: In a systematic review and meta-analysis, we found that ER should be considered as the first-line treatment for endoscopically resectable T1 colorectal cancers. In cases of noncurative resection, additional surgery can have comparable outcomes to primary surgery.

RESUMO

BACKGROUND: The aim of this study is to compare perioperative outcomes, readmission, and mortality after hemiarthroplasty for hip fractures in diabetic patients with different renal function statuses. METHODS: In this retrospective population-based cohort study, diabetic patients who received primary hemiarthroplasty for hip fracture between January 1997 and December 2013 were identified from the Taiwan National Health Insurance Research Database. Primary outcomes were perioperative outcomes including infection and revision. Secondary outcomes were all-cause readmission and mortality. RESULTS: A total of 29,535 diabetic patients were included: 8270 patients had chronic kidney disease (CKD group), 1311 patients underwent permanent dialysis (dialysis group), and 19,954 patients did not have CKD (non-CKD group). During a mean follow-up of 4.5 years, these 3 groups had comparable risks of any infection, including superficial and deep infection. Dialysis patients had a significantly higher risk of revision than did CKD and non-CKD patients (subdistribution hazard ratio 1.65, 95% confidence interval 1.16-2.36; subdistribution hazard ratio 1.57, 95% confidence interval 1.10-2.24, respectively). Compared with the non-CKD group, the dialysis group had significantly higher risks of readmission and mortality at all time points, namely 3 months after surgery, 1 year after surgery, and the final follow-up. The CKD group also had higher risks of readmission and mortality than did the non-CKD group at all time points. CONCLUSION: CKD is associated with poor outcomes following hemiarthroplasty for fragility hip fracture. CKD patients may have higher risks of surgical complications including revision than non-CKD patients, and they have significantly elevated risks of readmission and mortality.

RESUMO

PURPOSE: To evaluate knee strength, ligament stability, and functional outcomes in patients older than 50 years who underwent anterior cruciate ligament (ACL) reconstruction, and to compare these results with those obtained from a younger patient group (< 40 years). METHODS: Forty patients older than 50 years and 50 patients younger than 40 years who underwent ACL reconstruction were retrospectively studied. Isokinetic extensor and flexor muscle strength were evaluated. The peak torque was determined at speeds of 60°/s and 180°/s. The highest peak torque at each velocity was compared with that on the uninjured side. Patients were also evaluated for knee anteroposterior (AP) laxity and functional outcomes, which were measured by the Lysholm and International Knee Documentation Committee (IKDC) scores. All tests were evaluated at baseline and 1 year postoperatively. RESULTS: The groups were comparable at the baseline. Both groups had significant improvements in all parameters, including isokinetic muscle strength, AP laxity, and functional scores, at 1 year postoperatively (all p < 0.05). Compared with younger patients, older patients had similar results for extensor and flexor strength, AP laxity, and Lysholm score (n.s.). However, younger patients had better IKDC scores than did older patients [median 81.1; 95% confidence interval (CI) 95% CI 78.9-88.7 vs. median 75.6; 95% CI 70.1-79.3, p = 0.007]. CONCLUSIONS: Though with lower IKDC scores, older patients with ACL reconstruction had comparable results of knee strength and ligament laxity to younger patients. ACL reconstruction is recommended for treating patients older than 50 years with ACL insufficiency, especially for those with high functional demand. LEVEL OF EVIDENCE: Retrospective cohort study, III.

RESUMO

BACKGROUND: Patients with knee osteoarthritis (OA) were reported to have quadriceps weakness, and impaired proprioception, both related to pain and swelling. It is unclear whether pain alone a causal factor to above findings over the knee joint. The purpose of this study was to assess the effects of knee pain alone on the quadriceps strength, proprioception and dynamic balance in subjects with bilateral knee OA without joint swelling. METHODS: Fourty females with mean age of 68.3 years were involved in this cross-sectional study. The inclusion criteria were bilateral knee OA without joint swelling, with a visual analogue pain scale difference (> 1) between each knee. Patients all underwent assessment of the isokinetic strength of knee muscles, knee proprioceptive acuity, and dynamic balance. RESULTS: Patients' more painful knee had weaker isokinetic quadriceps strength than less painful knee at both 60 °/s and 180 °/s (p = 0.01, p = 0.01, respectively). There were no differences in proprioceptive acuity between both knees in all three knee positions. Meanwhile, there was a significant difference in the dynamic balance index measurement between both knees (more painful versus less painful: 3.88 ± 1.15 vs. 3.30 ± 1.00, p = 0.01). Quadriceps strength was associated with dynamic balance stability (60 °/s, r = - 0.578, p <  0.01; 180 °/s, r = - 0.439, p <  0.01). CONCLUSIONS: For patients with knee OA, the more painful knee was associated with weaker quadriceps and poor balance ability. To improve lower limb function and balance stability of the older persons having knee OA, physicians should take the optimal pain management strategy.

RESUMO

BACKGROUND: The effects of tranexamic acid (TXA) in the setting of shoulder arthroplasty are unclear. The objective of this study was to examine the effects of TXA in reducing the need for blood transfusions and blood loss in patients undergoing primary total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA). METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and retrospective cohort studies (RCS) that compared outcomes of patients who did and did not receive TXA during TSA or RTSA. We searched Cochrane Central Register of Controlled Trials, EMBASE, and MEDLINE for relevant studies. We assessed the risk of bias of the included studies and calculated pooled risk estimates. The primary outcome was transfusion rate, and secondary outcomes were changes in hemoglobin, estimated total blood loss (ETBL), blood loss via drainage, operative time, hospital stay, overall complications, and thromboembolic events. RESULTS: We identified 3 RCTs and 3 RCS including 677 patients with 680 shoulders (343 TXA and 337 non-TXA). The random-effects model meta-analysis showed that TXA group had a lower transfusion rate (risk ratio (RR) 0.34, 95% CI 0.14 to 0.79), less change in hemoglobin (mean difference (MD) -0.64 g/dl, 95% CI -0.81 to - 0.46), and reduced ETBL (MD -249.24 ml, 95% CI -338.74 to - 159.74). In patients with RTSA, the TXA group had a lower transfusion rate (RR 0.28, 95% CI 0.14 to 0.79), less ETBL (MD -249.15 ml, 95% CI -426.60 to - 71.70), less change in hemoglobin (MD - 0.64 g/dl, 95% CI -0.86 to - 0.42), and less blood loss via drainage (MD - 84.56 ml, 95% CI -145.72.14 to - 23.39) than non-TXA group. CONCLUSIONS: The use of TXA in primary shoulder arthroplasty appears safe, and can reduce transfusion rate, changes in hemoglobin, and perioperative total blood loss, especially in patients with RTSA. LEVEL OF EVIDENCE: Systematic Review and meta-analysis, III.

RESUMO

BACKGROUND: Increased body mass index (BMI) has been associated with poorer function in patients who have undergone anterior cruciate ligament (ACL) reconstruction. However, the effect of high BMI on muscle strength in these patients remained unclear. The current study aimed to compare knee muscle strength and Knee injury and Osteoarthritis Outcome Score (KOOS) in ACL-reconstructed patients with a variety of different BMIs. METHODS: From November 2013 to March 2016, we prospectively enrolled 30 patients who underwent ACL reconstruction (18-60 years of age). Anthropometric parameters, body compositions, isokinetic muscle strength and KOOS were assessed preoperatively, and at post-operative 16th week and 28th week. The patients were stratified into two groups by BMI, i.e. normal BMI (18.5-24.9 kg/m2) and high BMI (≥25.0 kg/m2). RESULTS: Twelve patients in the normal BMI group completed the follow-up, while sixteen patients did so in the high BMI group. In comparison of muscle strength between baseline and 28th week follow-up, the normal BMI group had significant increases in overall knee muscle strength, while the high BMI group only had increases in extensors of uninjured knee and flexors of the injured knee. However, there were significant increases in all KOOS subscales for the high BMI group. The high BMI patients reported increased KOOS, which may reflect the contribution of ligament stability in the presence of inadequate muscle strength. CONCLUSIONS: The normal BMI patients had improvement in all knee muscle strength following ACL reconstruction, while high BMI patients only had increases in certain knee muscles. High BMI patients had a decreased quadriceps muscle symmetry index, as compared to their normal BMI counterparts. Increases in quadriceps muscle strength of the uninjured knee and ACL reconstruction were associated with improvements in KOOS in high BMI patients.

RESUMO

PURPOSE: To investigate whether epinephrine in irrigation fluid improves visual clarity in arthroscopic shoulder surgery. METHODS: We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) that compared the surgical outcomes of patients who did and did not receive epinephrine during arthroscopic shoulder surgery. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, and Embase for relevant RCTs. We used the Cochrane Collaboration's tool to assess the risk of bias and adopted random-effects model meta-analysis to combine data. We used the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) methodology to evaluate the overall quality of the body of the retrieved evidence. The primary outcome was visual clarity. The secondary outcomes were operative time, amount of irrigation fluid, the need for increased pump pressure, and adverse cardiovascular events. RESULTS: This study included three RCTs with a total of 238 participants (124 in the epinephrine group and 114 in the non-epinephrine group). The use of epinephrine in irrigation fluid for shoulder arthroscopy achieved better visual clarity (standardized mean difference, 1.01; 95% confidence interval [CI] 0.63 to 1.39; p < 0.0001) and less need for increased pump pressure (risk ratio, 0.40; 95% CI 0.25 to 0.64; p = 0.0001) compared to the non-epinephrine group. No significant differences were noted in operative time (mean difference - 5.08; 95% CI - 14.46 to 4.31; p = 0.29) and amount of irrigation fluid (mean difference - 1.04; 95% CI - 2.38 to 0.39; p = 0.12) between the two groups. No adverse events were recorded in any of the included trials. CONCLUSIONS: The current evidence shows that the use of epinephrine in arthroscopic shoulder surgery may improve visualization and does not appear to have any major disadvantages. LEVEL OF EVIDENCE: Level I.

RESUMO

Plantar fasciopathy (PF) is the most common cause of heel pain. Extracorporeal shockwave therapy (ESWT) improves the gait pattern in patients with PF. However, the effects of ESWT on the biomechanics of the ankle in these patients remains unclear. Sixteen participants were included in the present study. Of the 16 participants, 8 patients with PF were assigned to receive extracorporeal shockwave therapy, and 8 healthy participants served as an external control group. ESWT was applied to the PF group for 1500 pulses at an energy flux of 0.26 mJ/mm2 every 3 weeks for 3 sessions. The biomechanics of the ankle joints were then assessed using an isokinetic dynamometer, and a health-related quality of life questionnaire was administered at baseline and at the final follow-up session 12 weeks after the initial treatment. Passive stiffness was calculated and compared between the foot affected with PF, the opposite foot, and both feet of those in the healthy control group. The Kruskal-Wallis 1-way analysis of variance with repeated measures was performed, and statistical significance was considered present at the 5% (p ≤ .05) level. Ankle dorsiflexion in the affected limb increased from 14° ± 3° to 17° ± 2° after ESWT (p < .05). No statistically significant differences were noted in the strength of dorsiflexion or plantarflexion at baseline and after ESWT. However, a statistically significant increase in the ratio of strength in ankle dorsiflexion versus plantarflexion was found after ESWT (p < .05). No differences in the passive stiffness of the ankle joint were demonstrated. Patients reported an improved physical function score after ESWT (p < .05). An increased dorsiflexion/plantarflexion torque ratio and maximal dorsiflexion associated with decreased pain might contribute to the improved physical function after ESWT for PF.

RESUMO

BACKGROUND: To assess the effects of tourniquet use in arthroscopic anterior cruciate ligament (ACL) reconstruction surgery. METHODS: We conducted a systematic review and meta-analysis of randomised controlled trials (RCTs) that compared surgical outcomes following tourniquet use against non-tourniquet use during ACL reconstruction surgery. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE for relevant RCTs. We used the Cochrane Collaboration's tool to assess the risk of bias of included RCTs, and performed a random-effects meta-analysis in calculating the pooled risk estimates. The primary outcomes was postoperative pain measured by visual analogue scale, verbal rating scale, or required morphine dose. The secondary outcomes were blood loss in drainage, operative time, muscle strength, and calf and thigh girth. RESULTS: We included 5 RCTs with 226 participants (116 in the tourniquet group and 110 in the non-tourniquet group). Postoperative pain and morphine doses were not significantly different between the two groups. Compared to the non-tourniquet group, the tourniquet group had a significantly increased blood loss in the drain (mean difference: 94.40 ml; 95% CI 3.65-185.14; P = 0.04). No significant differences in the operative time and muscle strength were found between the two groups. Tourniquet use was associated with a greater decrease in thigh girth but not in calf girth. CONCLUSIONS: The current evidence shows that compared to tourniquet use, ACL reconstruction surgery without tourniquet does not appear to have any major disadvantages and does not prolong operation time. There might be less drain blood loss associated with tourniquet use, though drains are no longer routinely used in ACL reconstruction surgery.

RESUMO

BACKGROUND: Accumulating data shows that exon 19 deletions and L858R, both activating epidermal growth factor receptor mutations in non-small-cell lung cancers (NSCLCs), are just two different entities in terms of prognosis and treatment response to tyrosine kinase inhibitors (TKIs). METHODS: A systematic review and meta-analysis of randomized controlled trials comparing TKIs with conventional chemotherapy was performed. Eight trials of 1498 patients and five trials of 1279 patients with either exon 19 deletions or L858R were included in the meta-analysis. RESULTS: TKI treatment demonstrated progression-free survival benefit in patients with exon 19 deletions (hazard ratio (HR): 0.27, 95% confidence interval (CI): 0.21-0.35) and L858R (HR: 0.45, 95% CI: 0.35-0.58). Patients with exon 19 deletions had significant overall survival (OS) benefit under TKI treatment (HR: 0.72, 95% CI: 0.60-0.88). Subgroup analyses showed that irreversible TKIs, but not reversible TKIs, had statistically significant OS benefit in these patients (irreversible TKIs, HR: 0.59, 95% CI: 0.47-0.73; reversible TKIs, HR: 0.84, 95% CI: 0.69-1.02). Patients with L858R demonstrated no OS benefit under first-line TKI use (HR: 1.15, 95% CI: 0.95-1.39). CONCLUSIONS: In patients with advanced NSCLC harbouring exon 19 deletions, TKIs are associated with better OS compared with conventional chemotherapy. Future clinical trials should take exon 19 deletions and L858R as distinct disease entities and evaluate the treatment efficacy separately.

RESUMO

BACKGROUND: Stoma reversal is a surgical procedure commonly used following temporary defunctioning stoma surgery. Surgical site infection is one of the most common postoperative morbidities. A few skin closure methods have been developed to decrease surgical site infection. However, the optimal skin closure method is still in debate. OBJECTIVE: The aim of this study was to compare the surgical site infection rate and other postoperative outcomes between the pursestring closure and conventional primary closure techniques. DATA SOURCES: We searched the MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials for relevant trials. STUDY SELECTION: We conducted a meta-analysis of randomized controlled trials that compared the surgical outcomes following pursestring closure and conventional primary closure techniques. INTERVENTION: We conducted the meta-analysis by using the random-effects model. MAIN OUTCOME MEASURES: The primary outcome of interest was surgical site infection following stoma reversal within 30 days after operation. RESULTS: This meta-analysis included 4 randomized controlled trials with a total of 319 participants (162 in the pursestring closure group and 157 in the conventional primary closure group). Compared with the conventional primary closure group, the pursestring closure group had a significant decrease in surgical site infection (risk difference, -0.25; 95% CI, -0.36 to -0.15; p < 0.00001; number needed to treat = 4) and higher satisfaction with cosmetic outcomes (standard mean difference, 0.7; 95% CI, 0.13-1.27; p = 0.02). No other significant differences in operative time, length of hospital stay, and wound healing time were found between the 2 groups. LIMITATIONS: This study was limited to the lack of double blinding and long-term follow-up in the included trials. CONCLUSIONS: Pursestring closure has significantly fewer surgical site infections and achieves better cosmetic outcomes following stoma reversal than conventional primary closure.

RESUMO

BACKGROUND: The distal tibial metaphysis is located in the lower (distal) part of the tibia (shin bone). Fractures of this part of the tibia are most commonly due to a high energy injury in young men and to osteoporosis in older women. The optimal methods of surgical intervention for a distal tibial metaphyseal fracture remain uncertain. OBJECTIVES: To assess the effects (benefits and harms) of surgical interventions for distal tibial metaphyseal fractures in adults. We planned to compare surgical versus non-surgical (conservative) treatment, and different methods of surgical intervention. SEARCH METHODS: We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (9 December 2014), the Cochrane Central Register of Controlled Trials (2014, Issue 12), MEDLINE (1946 to November Week 3 2014), EMBASE (1980 to 2014 Week 48), the Airiti Library (1967 to 2014 Week 8), China Knowledge Resource Integrated Database (1915 to 2014 Week 8), ClinicalTrials.gov (February 2014) and reference lists of included studies. SELECTION CRITERIA: We included randomised and quasi-randomised controlled clinical studies comparing surgical versus non-surgical (conservative) treatment or different surgical interventions for treating distal tibial metaphyseal fractures in adults. Our primary outcomes were patient-reported function and the need for secondary or revision surgery or substantive physiotherapy because of adverse outcomes. DATA COLLECTION AND ANALYSIS: Two authors independently selected studies, assessed the risk of bias in each study and extracted data. We resolved disagreement by discussion and, where necessary, in consultation with a third author. Where appropriate we pooled data using the fixed-effect model. MAIN RESULTS: We included three randomised trials that evaluated intramedullary nailing versus plating in 213 participants, with useable data from 173 participants of whom 112 were male. The mean age of participants in individual studies ranged from 41 to 44 years. There were no trials comparing surgery with non-surgical treatment. The three included trials were at high risk of performance bias, with one trial also being at high risk of selection, detection and attrition bias. Overall, the quality of available evidence was rated as very low for all outcomes, meaning that we are very unsure about the estimates for all outcomes.The results of two large ongoing trials of nailing versus plating are likely to provide sufficient evidence to address this issue in a future update. AUTHORS' CONCLUSIONS: Overall, there is either no or insufficient evidence to draw definitive conclusions on the use of surgery or the best surgical intervention for distal tibial metaphyseal fractures in adults. The available evidence, which is of very low quality, found no clinically important differences in function or pain, and did not confirm a difference in the need for re-operation or risk of complications between nailing and plating.The addition of evidence from two ongoing trials of nailing versus plating should inform this question in future updates. Further randomised trials are warranted on other issues, but should be preceded by research to identify priority questions.

RESUMO

Arthritic knees with advanced valgus deformity present with soft tissue and osseous anomalies that make total knee arthroplasty (TKA) difficult. We conducted a retrospective chart review of 41 patients (51 knees) to determine whether computer-assisted surgery-TKA (CAS-TKA) is superior to TKA using conventional guiding systems. A significantly higher rate of lateral retinaculum release as well as outlier of sagittal mechanical axes and position of the femoral component (femoral flexion and femoral rotational angle) was recorded in the conventional TKA group versus the CAS-TKA group. Both groups had significant postoperative improvement in clinical performance, but results did not differ significantly between groups. Despite its radiographic benefit, CAS-TKA showed no significant benefit over TKA in short-term clinical functional outcomes when performed by an experienced surgeon.
