Comparison of daytime and after-hours surgical treatment of supracondylar humeral fractures in children

Pediatric Supracondylar Humerus Fracture: When Should We Surgically Treat? A Case-Series

Background/Objectives: Supracondylar humerus fractures (SCHFs) are the most common pediatric elbow injuries and often require surgical intervention. Despite guidelines, optimal timing for surgical management, particularly for cases without neurovascular compromise, remains unclear. This study evaluates the influence of surgical timing on short-term outcomes, focusing on fracture reduction quality and surgical parameters. Methods: In total, 62 pediatric patients who had been treated for Gartland type II and III SCHF between 2018 and 2023 were retrospectively assessed. Patients were grouped based on time of admission (morning, afternoon, early evening, and night shifts) and time to surgery (<12 h vs. >12 h). Primary outcomes included immediate radiological reduction, assessed via the Baumann's angle (BA) and shaft-condylar angle (SCA). Secondary outcomes encompassed surgery duration and radiation exposure. Statistical analyses used ANOVA and chi-square tests, with p < 0.05 considered significant. Results: No significant differences were observed in BA (p = 0.84) or SCA (p = 0.79) between early and delayed surgical groups. Similarly, surgical timing (shift or delay >12 h) did not significantly affect surgery duration (p = 0.92) or radiation exposure (p = 0.12). The complication rate was 6.45%. Conclusions: Surgical timing, including delays beyond 12 h, does not adversely affect short-term outcomes in SCHFs. However, after-hours procedures may pose practical challenges, emphasizing the importance of surgeon experience and institutional protocols. Larger prospective studies are warranted to validate these findings and examine them in the long term.

Time of surgery and surgeon level in supracondylar humerus fractures in pediatric patients: A retrospective study

BACKGROUND

Supracondylar humerus fractures account for more than 60% of all elbow fractures and about 1/5 of all pediatric fractures. Unfortunately, these fractures can be associated with risk of complications including neurovascular injuries, malunions and limb deformities. Controversy exists regarding the effect of time of surgical intervention and/or level of surgeon performing the surgery on outcome of these fractures.

AIM

To determine whether time of surgical intervention and/or surgeon level influence the outcomes of surgically managed pediatric supracondylar humerus fractures.

METHODS

We retrospectively studied 155 pediatric patients presenting with a supracondylar humerus fracture in a level 1 trauma center from January 2006 to December 2019. The data extracted included demographic data, fracture characteristics, surgical data, and follow-up outcomes. The collected data was analyzed and P values of < 0.05 were considered statistically significant.

RESULTS

Of the cohort, 11% of patients had documented post-operative complications, of which the majority occurred in surgeries performed after day time working hours and in fractures requiring open reduction. While the lowest complication rate was found in surgeries performed by pediatric orthopaedic surgeons, this did not reach statistical significance.

CONCLUSION

In pediatric patients undergoing surgery for supracondylar fractures, we found a higher complication rate when surgeries were not performed during working hours. Surgeon level and training had no significant effect on the risk of post-operative complications.

Descriptive Study on Epidemiology, Clinical Presentation, Treatment, and Outcome of Supracondylar Fractures Treated in a Base Hospital of Sri Lanka: A Single-Center Study

INTRODUCTION

Supracondylar fractures are common pediatric elbow injuries, with management in developing countries presenting challenges due to limited resources, inadequate facilities, and a lack of trained personnel.

METHOD

This study aimed to describe the incidence, demographics, clinical presentation, treatment methods, and outcomes of supracondylar fractures treated at Ashraff Memorial Hospital (AMH)-Kalmunai, a base hospital in Sri Lanka. This is a retrospective descriptive study conducted between January 2019 and December 2020.

RESULTS

The study involved 79 children with supracondylar fractures. The majority of the children were male (70.9%) and their ages ranged from one to 15 years. The study identified falls as the most common presenting complaint (92.4%), followed by road traffic accidents (3.8%), native treatment (2.5%), and mismanagement (1.3%). The majority of fractures affected the right side (69.6%), while the remaining cases involved the left side (30.4%). Regarding the time duration from fracture to hospital presentation, a significant proportion of children sought medical attention on the same day (51.9%), followed by presentations within the first three days (38%), within a week (5.1%), or after a month (3.8%). Based on the Gartland classification, type I fractures accounted for 44.3% of cases, followed by type II fractures (29.1%) and type III fractures (26.6%). The most common treatment approach was closed reduction and percutaneous pinning (41.8%). Other treatment options included plaster of Paris (POP) cast without manipulation (36.7%), POP cast with manipulation (7.6%), analgesics alone (6.3%), and open reduction fixation (5.1%). Follow-up procedures varied, with routine cast removal (11.4%), routine cast and K-wire removal (45.6%), and re-do surgery with routine follow-up (1.3%). Among the type III fractures, two children presented with vascular compromise and anterior interosseous nerve (AIN) impairment, while another two children had AIN impairment only. Type I and type II fractures did not exhibit nerve involvement or vascular impairment. Only one out of the 79 children had an open fracture.

CONCLUSION

Supracondylar fracture is the most common orthopedic fracture in children. The study sheds light on the challenges and opportunities associated with treating pediatric supracondylar fractures in a resource-constrained context. The findings can help produce guidelines for the management of supracondylar fractures in underdeveloped nations, as well as contribute to global efforts to enhance the management of pediatric fractures.

Correlation of Fall Height, Fracture Severity and Clinical Outcome in Pediatric Supracondylar Fractures—A Retrospective Analysis with an Observation Period of 20 Years

The most common cause leading to supracondylar humerus fractures in children is falling onto an outstretched arm. A correlation between fall height and fracture severity may be assumed but has not yet been described. The aim of this study was to show that fracture severity increases with fall height. Furthermore, the correlation between fracture severity and outcome was examined. A total of 971 children with supracondylar humerus fractures between January 2000 and December 2019 were included in this study. The correlations between fall height and fracture severity and between fracture severity and outcome were assessed. Increasing fall height correlates with fracture severity (p < 0.001; r = 0.24). Furthermore, the incidence of complications increases with fracture severity and a correlation was present accordingly (p < 0.001; r = 0.28). A total of 30 (3.1%) patients showed limitations in range of motion and/or persistent neurologic deficits at the latest follow-up. Type I fractures rarely lead to subsequent limitations. The correlation between increasing fall height and fracture severity was significant. Furthermore, children with type III and IV supracondylar fractures are more likely to develop complications or restrictions in movement than children with type I and II fractures. Hence, the initial fall height may be an indirect indicator of a more or less favorable outcome.

Retrospective Mid-Term Follow-Up of Posttraumatic and Iatrogenic Neurovascular Complications in Surgically Treated Paediatric Patients with Distal Humerus Fracture

BACKGROUND

The purpose of the study was to investigate and describe neurovascular complications and mid-term clinical outcomes of operatively managed fractures of the distal humerus in a paediatric population. Neurovascular injuries are common in these fractures, but reports about their implications for mid-term clinical outcomes is sparse.

METHODS

A single-centre retrospective study was conducted at a university teaching hospital investigating paediatric patients who underwent operative management of a distal humerus fracture between 2014 and 2018. Patient demographics, fracture classification, pre-, peri- and postoperative neurovascular complications were investigated. Mid-term follow up clinical examination and functional scoring using QuickDASH, the Broberg and Morrey Score (BMS), the Mayo Elbow Performance Score (MEPS) and the Numeric Rating Scale were performed.

RESULTS

A total of 84 patients were identified, of which 34 met the inclusion criteria and were available for follow-up clinical examination. The average time to follow-up was 150 weeks (1049.44 days ± 448.54). Ten primary traumatic neurovascular complications were identified, the majority of which involved the median nerve. Primary traumatic dissection of the brachial artery was recorded in three patients. Secondary iatrogenic nerve injury was documented in five patients after previously normal clinical examination. At follow-up, the average QuickDASH score was 3.0 ± 4.3, BMS was 98.6 ± 3.4 and MEPS was 97.1 ± 3.3 points.

CONCLUSIONS

The mid-term clinical outcome following surgical management of distal humerus fractures is excellent. There is, however, a considerable frequency of both primary and secondary neurovascular complications, which must be considered when opting to treat these injuries surgically.

Pediatric Supracondylar Humerus Fractures: Should We Avoid Surgery during After-Hours?

Pediatric supracondylar humerus fractures occur frequently. Often, the decision has to be made whether to operate immediately, e.g., during after-hours, or to postpone until office hours. However, the effect of timing of surgery on radiological and clinical outcomes is unclear. This literature review with the PICO methodology found six relevant articles that compared the results of office-hours and after-hours surgery for pediatric supracondylar humerus fractures. The surgical outcomes of both groups in these studies were assessed. One of the articles found a significantly higher "poor fixation rate" in the after-hours group, compared with office hours. Another article found more malunions in the "night" subgroup vs. the "all groups but night" group. A third article found a higher risk of postoperative paresthesia in the "late night" subgroup vs. the "day" group. Lastly, one article reported increased consultant attendance and decreased operative time when postponing to office hours more often. No differences were reported for functional outcomes in any of the articles. Consequently, no strong risks or benefits from surgical treatment during office hours vs. after-hours were found. It appears safe to postpone surgery to office hours if circumstances are not optimal for acute surgery, and if there is no medical contraindication. However, research with a higher level-of-evidence is needed make more definite recommendations.

Performing Multiple Posterior Spinal Fusions in 1 Day: A Comparison of Perioperative Outcomes Between Morning and Afternoon Cases

BACKGROUND

High-volume centers for idiopathic scoliosis (IS) have difficulty in scheduling posterior spinal fusions (PSFs) due to operating room availability, particularly during school vacation. A solution is for 1 surgeon to perform 2 PSF cases back-to-back. This study aims to compare morning and afternoon PSF cases performed by the same surgeon for perioperative outcomes.

METHODS

A retrospective review of PSF cases for IS that occurred on the same day as another PSF by the same surgeon between January 2013 and December 2019 was conducted. Perioperative outcomes included surgical time, estimated blood loss, length of stay, and inpatient opioid consumption normalized by the patient's weight. Postoperative outcomes included complications, revision rate, curve correction, and patient-reported outcomes using the Scoliosis Research Society-30.

RESULTS

A total of 95 patients (87% female), mean age 15.6 years, were analyzed, with 48 morning cases and 47 afternoon cases. The median follow-up was 1.9 years (range: 0.3 to 6.1 y). Tests for equivalency determined equivalence in median anesthesia and mean surgical duration (P=0.05). The groups had similar initial curve correction (P=0.43) and rate of complications at 90 days postoperative (2 in each group for a total of 4 complications). No significant differences were seen between Scoliosis Research Society-30 scores at 6 months or in those who have reached 2 years postoperative.

CONCLUSIONS

Little literature exists on the safety of a surgeon performing 2 PSF cases in 1 day, particularly in regard to pain outcomes, 30- and 90-day complication rates, and quality of life measures. This study indicates that few differences in safety, pain, and quality of life outcomes may appear between morning and afternoon PSF cases.

Is there an optimal timing for surgical treatment of pediatric supracondylar humerus fractures in the first 24 hours?

Background

We aimed to determine the ideal surgical timing in the first 24 hours after admission to the hospital of pediatric supracondylar humerus fractures (SHF) that do not require emergent intervention.

Materials and Methods

Patients who underwent surgery in our institution between January 2011 and January 2019 due to pediatric Gartland type 3 SHFs were evaluated retrospectively. Open fractures, fractures associated with vascular injury and compartment syndrome, flexion type fractures were excluded. A total of 150 Gartland type 3 were included. The effect of early (<12 hours) or late (>12 hours) surgical interventions, daytime or night-time surgeries, working or non-working hour surgeries on operative parameters (operative duration and open reduction rate, reduction quality on postoperative early radiographs) were evaluated in pediatric SHFs.

Results

Early (<12 hours) or late (>12 hours), daytime or nighttime, working or non-working hour surgeries were found to be similar in Gartland type 3 patients regarding early postoperative reduction quality, duration of surgery, open reduction rate (p>0.05). Mean times passed from first admission to hospital until surgery were longer in working hour, late (>12 hours) and daytime surgery groups than non-working hour, early (<12 hours) and night-time surgery groups (p<0.001).

Conclusion

Although delaying the operation to the working hours seems to prolong the time until surgery in pediatric Gartland type 3 SHF patients who do not require emergent intervention such as open fractures, neurovascular impairment and compartment syndrome, there may not be a time interval that makes a difference for the patients if surgery is performed within the first 24 hours, thus the surgery could be scheduled according to the surgeons’ preference.

Management of acute paediatric fractures treated surgically in the UK: a cross-sectional study

INTRODUCTION

The epidemiology of acute paediatric orthopaedic trauma managed surgically across the NHS is poorly described. Compliance against national standards for the management of supracondylar humeral fractures is also unknown at a national level.

METHODS

Collaborators in 129 NHS hospitals prospectively collected data on surgically managed acute paediatric orthopaedic trauma cases. Data were collected over a seven-day period and included demographics, injury characteristics, operative details and timing of surgery. A national audit was also undertaken to evaluate compliance with the British Orthopaedic Association Standards for Trauma Guideline 11: Supracondylar Fractures of the Humerus in Children.

RESULTS

Data were captured on 770 surgically treated cases. The three most common injuries were forearm fractures of both bones (n = 235), distal radius fractures (n = 194) and supracondylar elbow fractures (n = 89). The mode day of injury was Friday (n = 136) and the mode day of surgery was Saturday (n = 138). 88% of supracondylar fractures received surgery on the day of presentation or the following day. Only 14% of supracondylar fractures were treated surgically after 8pm; 33/89 used 2.0mm Kirschner wires, 38/89 used 1.6mm wires and 2/89 used 1.2mm wires.

CONCLUSION

Forearm fractures of both bones, distal radius fractures and supracondylar humeral fractures were the three most common injuries treated surgically. There is wide variation in compliance against national standards in the management of supracondylar humeral fractures with 88% undertaking surgery on the day of or the day following presentation but only 37% using the recommended 2.0mm Kirschner wires.

Comprehensive Analysis of Pediatric Supracondylar Fractures in the Emergency Department; A Single Center Experience

Objective:

To describe the demographic characteristics and to assess possible risk factors related to the moment of presentation at Emergency Department (ED) for pediatric humeral supracondylar fractures.

Methods:

This was cross-sectional study being conducted during 5-year period from 2013 to 2017 at ED of a regional hospital in Spain. We have included all the pediatric patients (<14 years) with supracondylar fractures referring to our center during the study period. The demographic, clinical and radiological characteristics of the patients were recorded. The outcome and treatment strategies were also recorded. The risk factors of the pediatric supracondylar fracture was also assessed in our series.

Results:

We have included 52 pediatric patients with supracondylar fractures in this series. The mean age was 7.48 ± 2.97 years with a minimum age of 2 years and a maximum of 14 years. Among the patients there were 32 (61.54%) male and 20 (38.46%) female. Age less than 7 years found to be a protective factor against unstable fractures [OR 0.33 (0.10 - 1.02)]. Fractures presented during daytime hours showed a greater instability [OR 3.49 (1.07-11.39)]. However, the risk of presentation at nighttime was higher during the summer months (June to September).

Conclusion:

The older is the child, the greater is the risk of suffering an unstable fracture, which increases the need for surgery. This risk is greater during the daytime. Otherwise, during the summer months, there is a higher risk of patient presentation at nighttime.

Independent predictors affecting the reduction of pediatric supracondylar humerus fractures: a retrospective cohort study

BACKGROUND

Although it is important to understand the risk factors affecting the reduction of pediatric supracondylar humerus fractures (PSHFs), no inclusive study has been conducted so far. We performed a retrospective cohort study to identify the risk factors affecting the quality and difficulty of reduction for PSHFs.

METHODS

We reviewed 160 cases with a PSHF that had been surgically treated in our hospital between January 2007 and December 2019. We investigated age, sex, injured side, body mass index (BMI), modified Gartland classification, neurological deficit or an absent radial artery pulse at an initial examination, start time of the operation, waiting time from injury to surgery, operative time, reduction technique, and perioperative radiographic parameters. We calculated independent predictors of unsuccessful closed reduction, prolonged operative time, and malreduction using multivariate analyses.

RESULTS

In a logistic regression analysis, modified Gartland type III was a significant predictor of unsuccessful closed reduction (OR 14.50 [95% CI 4.03-51.90]; P < 0.01) and BMI was a significant predictor of malrotation (OR 1.59 [95% CI 1.06-2.39]; P = 0.025). In a multiple linear regression analysis, BMI and open reduction were significant predictors of prolonged operative time (BMI, P = 0.011; open reduction, P < 0.01).

CONCLUSIONS

If closed reduction fails, we should not hesitate to immediately switch to other methods. Obesity was an independent predictor of both prolonged operative time and malrotation, a finding that has not been previously reported. Rotational alignment should be carefully checked, especially for obese children, and accurately be reduced. Open reduction also extended operative time.

After-hours elective spine deformity corrective surgery for patients with Adolescent Idiopathic Scoliosis: Is it safe?

OBJECTIVE

The aim of this study was to compare the outcome of after-hours electively planned Posterior Spinal Fusion surgeries for Adolescent Idiopathic Scoliosis (AIS) patients with daytime surgeries.

METHODS

This was a retrospective propensity score-matched study using prospectively collected data. Surgeries performed between 08:00 and 16:59 h were labeled as daytime surgeries (group 1) and surgeries performed between 17:00 and 06:00 h were labeled as after-hours surgeries (group 2). The perioperative outcome parameters were average operation time in and out, operation duration, intraoperative blood loss, blood transfusion, intraoperative hemodynamic parameters, preoperative hemoglobin, postoperative hemoglobin, and total patient-controlled anesthesia (PCA) morphine usage. Radiological variables assessed were Lenke subtypes, preoperative Cobb angle, number of fusion levels, number of screws used, postoperative Cobb angle, correction rate, side bending flexibility, side bending correction index, complications rate, and length of hospitalization.

RESULTS

Average operation time in for daytime group was 11:32 ± 2:33 h versus 18:20 ± 1:05 h in after-hours group. Comparing daytime surgeries with after-hours surgeries, there were no significant differences ( p > 0.05) in the operation duration, intraoperative blood loss, intraoperative pH, bicarbonate, lactate, postoperative hemoglobin, hemoglobin drift, blood transfusion, postoperative Cobb angle, correction rate, side bending flexibility, side bending correction index, length of hospitalization, and complications rate. Total PCA morphine usage was significantly lesser in the after-hours group (18.2 ± 15.3 mg) compared with the daytime group (24.6 ± 16.6 mg; p = 0.042).

CONCLUSIONS

After-hours elective spine deformity corrective surgeries for healthy ambulatory patients with AIS were as safe as when they were done during daytime.

Perioperative Outcome of Severe Idiopathic Scoliosis (Cobb Angle ≥ 90°): Is There Any Difference Between "Daytime" Versus "After-hours" Surgeries?

STUDY DESIGN

Retrospective study from a prospectively collected database.

OBJECTIVE

To compare the perioperative outcome between after-hours and daytime surgery carried out by a dedicated spinal deformity team for severe Idiopathic Scoliosis (IS) patients with Cobb angle ≥ 90°.

SUMMARY OF BACKGROUND DATA

There were concerns that after-hours corrective surgeries in severe IS have higher morbidity compared to daytime surgeries.

METHODS

Seventy-one severe IS patients who underwent single-staged Posterior Spinal Fusion (PSF) were included. Surgeries performed between 08:00H and 16:59H were classified as "daytime" group and surgeries performed between 17:00H and 06:00H were classified as "after-hours" group. Perioperative outcome parameters were average operation start time and end time, operation duration, intraoperative blood loss, intraoperative hemodynamic parameters, preoperative and postoperative hemoglobin, blood transfusion rate, total patient-controlled anesthesia (PCA) morphine usage, length of postoperative hospitalization, and complications. Radiological variables assessed were preoperative and postoperative Cobb angle, side bending flexibility, number of fusion levels, number of screws used, Correction Rate, and Side Bending Correction Index.

RESULTS

Thirty patients were operated during daytime and 41 patients were operated after-hours. The mean age was 16.1 ± 5.8 years old. The mean operation start time for daytime group was 11:31 ± 2:45H versus 19:10 ± 1:24H for after-hours group. There were no significant differences between both groups in the operation duration, intraoperative blood loss, intraoperative hemodynamic parameters, postoperative hemoglobin, hemoglobin drift, transfusion rate, length of postoperative hospitalization, postoperative Cobb angle, Correction Rate, and Side Bending Correction Index. There were four complications (1 SSEP loss, 1 massive blood loss, and 2 superficial wound infections) with no difference between daytime and after-hours group.

CONCLUSION

After-hours elective spine deformity corrective surgeries in healthy ambulatory patients with severe IS performed by a dedicated spinal deformity team using dual attending surgeon strategy were as safe as those performed during daytime.

Risk factors for relaparotomy after cesarean section due to hemorrhage: a tertiary center experience

Aim: This study aimed to examine the risk factors for relaparotomy after cesarean section (RLACS) due to bleeding.Material and methods: In this retrospective descriptive case-control study, women who underwent RLACS only for bleeding between 2008 and 2019 at a single tertiary center were examined (the center oversees approximately 25,000 deliveries per year). Maternal characteristics, postoperative findings, and surgical features were compared with a control group that included non-complicated cesarean sections (CS). Multivariable logistic regression analysis was used to identify the risk factors for relaparotomy.Results: Relaparotomy complicated 0.07% (n = 40) of CS during the study period (n = 58,095). When compared with the control group, age, parity, estimated blood loss (EBL), postoperative pulse, blood replacement, and length of hospital stay were statistically higher in patients undergoing relaparotomy, whereas their postoperative systolic and diastolic blood pressure were found to be low. A history of pelvic surgery, the need for intensive care, and complications were more frequent in patients undergoing relaparotomy. When CSs were grouped according to 8-h periods of the day, it emerged that relaparotomies were mostly performed on the patients who underwent CS after working hours. Time interval during the day of the CS [OR: 2.59 (1.10-6.12)] and high postoperative pulse rate [OR: 1.58 (1.28-1.96)] were found to be independent risk indicators for RLACS (AUC: 0.97).Conclusions: Monitoring vital signs in the postoperative period and increasing the number of physicians and nurses during off-hours in hospitals working with on-call duty procedures as determined by the Ministry of Health will reduce the incidence rate of relaparotomy, maternal morbidity, and mortality due to hemorrhage.

Delaying Surgery in Type III Supracondylar Humerus Fractures Does Not Lead to Longer Surgical Times or More Difficult Reduction

OBJECTIVE

To determine if delay in surgical treatment of type III supracondylar humerus fracture would affect the length of operative time.

DESIGN

Retrospective cohort study.

SETTING

Level 1 trauma center.

PATIENTS/PARTICIPANTS

This is a series of 309 modified Gartland type III supracondylar fractures treated operatively from 2011 to 2013.

INTERVENTION

Fifteen hours was defined as the cutoff between early and delayed treatment. A total of 53.7% (166/309) fractures were treated early, and 46.4% (143/309) were delayed.

MAIN OUTCOME MEASUREMENTS

Surgical time was defined as "incision start" to "incision close." Fluoroscopy time was used as a surrogate for difficulty of reduction.

RESULTS

Time from injury to operating room was shorter for high-energy fractures (fractures with soft-tissue or neurovascular injury) versus low-energy fractures (12.9 vs. 15.3 hours, P < 0.0001); however, surgical time (37.3 vs. 31.8 minutes, P = 0.004) and fluoroscopy time (54.6 vs. 48.6 seconds, P = 0.027) were longer in high-energy fractures versus low-energy fractures. Among low-energy fractures, no significant difference was detected in the surgical time between the early and delayed treatment groups or in the fluoroscopy time. In addition, there was no statistically significant difference found in the surgical or fluoroscopy time with the presence of a surgical assistant.

CONCLUSIONS

Delay in surgery did not result in a longer surgical time or more difficult reduction for type III supracondylar humerus fracture. Patients with low-energy fractures still underwent a shorter operative time even with delay from injury to surgery.

Pinning of supracondylar fractures in children - Strategies to avoid complications

In the pediatric population supracondylar humerus fracture (SHF) is one of the most common injuries. Diagnosis is based on inspection and conventional radiography. SHFs should be classified according to the modified Gartland classification, which guides treatment. Non-displaced or minimally displaced fractures (Gartland type-I) should be treated non-operatively, completely displaced type III fractures require closed reduction and K-wire fixation. In type-II fractures, important landmarks, such as the anterior humeral line (Roger´s line), the shaft-physeal angle (Baumann´s angle) and the shaft condylar angle should be considered to guide treatment. Special attention has to be paid for potential rotational dislocation, which is indicated by a ventral spur. In such cases surgery is necessary. The degree of acceptable extension malpositioning depends on patient´s age. In 10-year-old children fractures with a shaft condylar angle of more than 15° are still suitable for non-operative therapy. Timing for surgery is controversially discussed. Postponing surgery to the next day seems reasonable if absence of pain, intact soft tissue and normal neurovascular status are present. Neurovascular complications are not uncommon, especially in Gartland type-III fractures and in cases with additional forearm injuries. A white hand without palpable pulse needs emergency surgery, the management of the pulseless pink hand is still controversially discussed. Different operative techniques exist for surgical treatment. The golden standard is closed reduction and percutaneous K-wire pinning. Crossed pinning seems to achieve best biomechanical stability. Since ulnar nerve injuries are reported to occur in 6% after medially inserting K-wires, lateral divergent insertion of two K-wires has been compared to crossed pinning fixation in several randomized controlled trials. Meta-analyses demonstrated a higher risk for ulnar nerve injury for the crossed pinning technique while risk for loss of fixation was higher in lateral only pinning. In both cases, K-wires should be removed 3-6 weeks after surgery with consolidation of the fracture. Clinical and radiological follow-up should be carried out at 3 weeks post fracture fixation to rule out loss of reduction. If this should occur, early revision surgery has been demonstrated beneficial.

Early versus delayed surgery for paediatric supracondylar humeral fractures in the absence of vascular compromise: a systematic review and meta-analysis

AIMS

We set out to determine if there is a difference in perioperative outcomes between early and delayed surgery in paediatric supracondylar humeral fractures in the absence of vascular compromise through a systematic review and meta-analysis.

MATERIALS AND METHODS

A literature search was performed, with search outputs screened for studies meeting the inclusion criteria. The groups of early surgery (ES) and delayed surgery (DS) were classified by study authors. The primary outcome measure was open reduction requirement. Meta-analysis was performed in the presence of sufficient study homogeneity. Individual study risk of bias was assessed using the Risk of Bias in Non-Randomised Studies - of Interventions (ROBINS-I) criteria, with the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) criteria used to evaluate outcomes independently.

RESULTS

A total of 12 studies met the inclusion criteria (1735 fractures). Pooled mean time to surgery from injury was and 10.7 hours for ES and 91.8 hours for DS. On meta-analysis there was no significant difference between ES versus DS for the outcome of open reduction requirement. There was also no significant difference for the outcomes: Iatrogenic nerve injury, pin site infection, and re-operation. The quality of evidence for all the individual outcomes was low or very low.

CONCLUSIONS

There is no evidence that delaying supracondylar fracture surgery negatively influences outcomes in the absence of vascular compromise. There are, however, notable limitations to the existing available literature.
