Comparison of Open and Closed Hand Fractures and the Effect of Urgent Operative Intervention

[Open Fractures of the Hand: is there No Alternative to Definitive Osteosynthetic Treatment in an Emergency Situation?]

There is an emergency indication for the treatment of open fractures. Fracture stabilisation and soft tissue care are equal prerequisites for an uncomplicated course of treatment and a good functional result. However, challenges arise in cases of extensive wound contamination and compromised perfusion, limiting options for stable osteosynthesis in emergency situations. Furthermore, resource constraints may pose a challenge to adhering strictly to the six-hour time window. This prompts deliberations on whether, under certain circumstances, a deviation from the conventional approach is feasible by exploring the possibility of prioritising immediate surgical wound care during emergencies, with definitive fracture care deferred to a later point in time. Between 2019 and 2021, 301 patients with open fractures of the hand skeleton were treated (median age 44 years, 85% male, 15% female). Definitive treatment was carried out as a primary emergency procedure in 215 patients (group A), whereas it was performed at an interval after an average of 3 days in 86 patients (group B), who had received surgical wound care, splint placement, and antibiotic coverage on the day of the injury. In a retrospective study, the following criteria were analysed: comorbidities, injury patterns, injury location, timing of treatment, number of follow-up procedures, infection rate, and duration of hospitalisation. The course was complicated by infection in six patients (1.9%). Five of these patients were in group A (infection rate 2.3%), and only one patient was in group B (infection rate 1.1%). All six infections occurred after crush injuries, all at the fingertip or end joint. These numbers underscore the relevance of soft tissue trauma and primary stump formation. Comorbidities were not statistically significant in our study with a view to the occurrence of infection. In conclusion, it can be stated that, with antibiotic protection, definitive treatment of an open fracture in an interval is possible if it is preceded by initial emergency surgical wound care with subsequent immobilisation.

Management of Open Fractures of the Extremities and Pediatrics

The modern management of open fractures was established after the foundational work of Gustilo and Anderson, but we continue to strive to determine the optimal treatment of open fractures to diminish the risk of infection. The ideal timing of antibiotics, presentation to the operating room, and timing of procedures such as flap coverage continue to be investigated with incremental changes recommended over the years. This article aims to provide the most recent review of the literature regarding the timing and management of both upper and lower extremity open fractures, pediatric open fractures, current topics of controversy, and the data supporting current treatment recommendations.

Open hand fractures: a prospective analysis of functional outcomes and risk factors for infection after initial management in the emergency department

PURPOSE

Open hand fractures are common orthopaedic injuries, historically managed with early debridement in the operating room. Recent studies suggest immediate operative treatment may not be necessary but have been limited by poor follow-up and lack of functional outcomes. This study sought to prospectively evaluate these injuries treated initially in the emergency department (ED), without immediate operative intervention, to determine long-term infectious and functional outcomes using the Michigan Hand Outcomes Questionnaire (MHQ).

METHODS

Adult patients with open hand fractures managed initially in the ED at a Level-I trauma center were considered for inclusion (2012-2016). Follow-up and MHQ administration occurred at 6 weeks, 12 weeks, 6 months, and 1 year. Logistic regression and Kruskal-Wallis testing were used for analysis.

RESULTS

Eighty-one patients (110 fractures) were included. Most had Gustilo Type III injuries (65%). Injury mechanisms most commonly included saw/cut (40%) and crush (28%). Nearly half of all patients (46%) had additional injuries involving a nailbed or tendon. Fifteen percent of patients had surgery within 30 days. The average follow-up was 8.9 months, with 68% of patients completing at least 12 months. Eleven patients (14%) developed an infection, of which 4 (5%) required surgery. Subsequent surgery and laceration size were associated with increased odds of infection, and at one-year, functional outcomes were not significantly different regardless of fracture classification, injury mechanism, or surgery.

CONCLUSIONS

Initial ED management of open hand fractures results in reasonable infection rates compared to similar literature and functional recovery demonstrated by MHQ score improvements over time.

Complications in Hand Surgery During Early Independent Practice: A Single Surgeon's 5-Year Experience

BACKGROUND

The objective of this study was to understand the frequency and types of complications, and the associated postoperative outcomes within the first 5 years of practice after hand and upper extremity surgery fellowship.

METHODS

This was a retrospective observational study of all patients seen and surgically treated by a single surgeon at a single institution from August 2014 to September 2019. This corresponded to the first 5 years of practice after fellowship. Data collected included patient demographics, perioperative data, complication type, and outcome of the complication (better/same/worse than preoperative status). Complications were classified using the Clavien-Dindo system and a unique, self-derived system.

RESULTS

In total, 3301 surgeries were performed during the first 5 years of practice. The overall complication rate was 7.9% (261 complications from 239 patients). The 30-day complication rate was 5.2% (171/3301). Eleven (4.2%) of the 261 complications occurred intraoperatively. The total number of complications significantly declined during the first 5 years of practice as follows: 74, 71, 46, 37, and 33 (P = .010, R2 = .92). Hand and wrist were the most frequent anatomic locations involved and bone pathology was the predominant indication.

CONCLUSION

The overall surgical complication rate for hand and upper extremity surgery was 7.9%, with a 30-day complication rate of 5.2% (171/3301). The rate of complications after fellowship declined over the first 5 years of independent practice. Superficial infections were the most common complication. More than 90% of patients ultimately improved after addressing the complication.

Impact of Missing Data on Identifying Risk Factors for Postoperative Complications in Hand Surgery

BACKGROUND

The mismanagement of missing data in large clinical databases may lead to inaccurate findings. The purpose of this study was to demonstrate the effects of missing data on hand surgery research findings using an analysis of postoperative morbidity in patients undergoing hospital-based hand surgery.

METHODS

The National Surgical Quality Improvement Program database was queried for patients undergoing common hand and upper extremity surgery between 2011 and 2016. Major and minor postoperative complications were identified. Demographics, comorbidity, and preoperative laboratory values were identified, and the percentage missing of each was tabulated. To demonstrate how missing data can alter analysis results, these variables were evaluated for an association with major complications using multivariable regression on 3 separate cohorts: (1) all patients; (2) all patients after exclusion of any patient entry with >10% of missing data; and (3) after removal of any patient entry with any missing data.

RESULTS

Groups 1, 2, and 3 had 48 370, 23 118, and 6280 patients, respectively. There were 14 variables associated with increased odds of major complications in group 1, yet only 10 and 9 variables for groups 2 and 3, respectively. Six variables were associated with increased major complications across all 3 groups, whereas only 1 was associated with decreased odds of major complications across all groups.

CONCLUSIONS

Filtering patient cohorts according to the amount of missing patient information affected analyses of predictors for major complications associated with hospital-based hand surgery. These findings highlight the importance of considering and addressing missing data in large database studies.

A comparative study of thumb reconstruction through the transplant of the first toe compound free flap between emergency surgery and elective surgery

This study compared emergency surgery with elective surgery for thumb reconstruction to explore the advantages, safety, and clinical value of emergency reconstruction. By comparing the advantages and disadvantages of thumb reconstruction in emergency surgery and elective surgery, it provides data support for optimizing the treatment process and methods. In this study, 22 patients who underwent thumb reconstruction in Rizhao people's Hospital from January 2018 to December 2020 were randomly divided into emergency operation group and elective operation group. The differences in operation period, hospitalization time, postoperative complications, hand function score, and satisfaction score between the 2 groups were analyzed. The operation period and hospitalization time of patients in the emergency surgery group were significantly lower than those in the elective surgery group, with statistical significance (P < .05). There was no significant difference in postoperative complications between the 2 groups (P > .05). After 3 months of rehabilitation training, the 2-point discrimination, functional score, and satisfaction score of the reconstructed thumb in the emergency surgery group were higher than those in the elective surgery group, and the difference was statistically significant (P < .05). Emergency reconstruction of the thumb can reduce operation time and hospitalization time, reduce operation costs, and obtain a more ideal appearance and function.

Factors Associated With Implant Removal Following Plate-and-Screw Fixation of Isolated Metacarpal Fractures

PURPOSE

The incidence of and associated risk factors for implant removal following the plate-and-screw fixation of metacarpal shaft fractures have not been well described. The primary objective of our study was to identify implant-related radiographic parameters associated with implant removal in patients treated with the plate-and-screw fixation of isolated, displaced metacarpal fractures at 2 years of follow-up. The secondary objective of our study was to identify patient-related factors associated with implant removal.

METHODS

A retrospective study of all patients who underwent open treatment of a metacarpal fracture with a plate-and-screw construct from January 1, 2000, to April 30, 2019, at 2 level-1 trauma centers was conducted. After the application of exclusion criteria, we identified 138 patients with a single isolated metacarpal fracture of a nonthumb digit treated with open reduction and internal fixation using a plate-and-screw construct. Our study endpoint was the removal of the plate-and-screw construct or a minimum of 2 years of follow-up without the removal of the hardware. Twenty-three patients achieved our study endpoint as determined using their electronic medical records, and 58 additional patients were reached via telephone to confirm their implant removal status. A bivariate analysis was used to screen for factors associated with implant removal, and variables significant in the bivariate screen were included in a multivariable stepwise logistic regression model.

RESULTS

Twenty-three out of 81 patients (28%) in our final cohort underwent implant removal by the final follow-up visit. In the logistic regression analysis, the distance between the plate and metacarpophalangeal joint, the distance between the plate and carpometacarpal joint, and active smoking were independently associated with implant removal.

CONCLUSIONS

The proximity of metacarpal plates to adjacent joints is associated with subsequent implant removal. Patients may be counseled about the higher risk of implant removal when periarticular metacarpal plating is performed.

Addressing Smoking in Musculoskeletal Specialty Care

➤

Physicians who advise patients to quit smoking substantially improve cessation rates, but cessation counseling is currently underperformed.

➤

Counseling, pharmacotherapy, and additional interventions can improve the chance of successful smoking cessation. Most patients require multiple attempts at quitting to be successful.

➤

A list of referral contacts and resources should be developed and routinely offered to these patients. The national Quitline (1-800-QUIT-NOW) provides free access to trained counselors and "quit coaches" for each state program in the United States.

➤

Government and private insurance plans in the United States are required (in most cases) to cover the cost of 2 quitting attempts per year including counseling referrals and medications.

➤

Several biopsychosocial factors that affect orthopaedic outcomes (weight, anxiety, depression, etc.) are also relevant to smoking cessation; management of these factors is thus potentially aggregately advantageous.

Comparative Analysis of Open Reduction Internal Fixation and Closed Reduction Percutaneous Pinning of Hand Fractures: Single Academic Center Retrospective Review

PURPOSE

The purpose of our study was to compare postoperative outcomes between patients receiving closed reduction percutaneous pinning (CRPP) to open reduction internal fixation (ORIF) following metacarpal and phalanx fractures.

METHODS

A retrospective chart review was performed at a single academic center for all patients suffering a metacarpal or phalanx fracture and receiving either CRPP or ORIF between 2012 and 2018. Patients were divided into fracture mechanism, high-energy mechanism of injury, low-energy mechanism of injury, or unknown, and treatment of fracture with either ORIF or CRPP. High-energy mechanism of injury included gunshot wounds, motor vehicle crash, and blast injuries, whereas low-energy mechanism of injury included all other causes. Patient demographics, postoperative complications, 30-day readmission, and return to the operating room were recorded.

RESULTS

A total of 408 patients, with 524 fractures, were included in the study. There were 127 fractures that resulted from high-energy mechanisms and 394 fractures that resulted from low-energy mechanisms. Open reduction internal fixation was used to treat 299 fractures, whereas CRPP was used for 225 fractures. Among fracture fixation, there was a total of 8.4% complication rate with ORIF, accounting for 10.4% of complications, and CRPP accounting for 5.8%. Among the fracture mechanism, the high-energy mechanism of injury had a 21.3% complication rate, whereas the low-energy mechanism of energy was 4.3%. When comparing the above variables, only high-energy mechanism of injury was a statistically significant predictor of complications (odds ratio, 3.2; confidence interval, 1.5-7.0; P = 0.002). The average operating room time for the ORIF group was 124.82 minutes compared with 97.6 minutes for the CRPP group.

CONCLUSION

Patients with hand fractures corrected by ORIF appeared to have a higher postoperative complication rate. When the 2 procedures, ORIF and CRPP, were controlled for mechanism of injury, there was not a statistically significant difference in postoperative complication rate (P = 0.14). However, a fracture sustained by a high-energy mechanism was a statistically significant predictor of postoperative complications (P = 0.002).

Mortality and pulmonary complications in patients undergoing upper extremity surgery at the peak of the SARS-CoV-2 pandemic in the UK: a national cohort study

Introduction

This study reports the 30-day mortality, SARS-CoV-2 complication rate and SARS-CoV-2-related hospital processes at the peak of the first wave of the pandemic in the UK.

Methods

This national, multicentre, cohort study at 74 centres in the UK included all patients undergoing any surgery below the elbow at the peak of the UK pandemic. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The secondary outcomes were SARS-CoV-2 complication rates and overall complication rates. A clinician survey relating to SARS-CoV-2 safety processes was carried out for each participating centre.

Results

This analysis includes 1093 patients who underwent upper limb surgery from the 1 to 14 April 2020 inclusively. The overall 30-day mortality was 0.09% (1 pre-existing SARS-CoV-2 pneumonia) and the mortality of day case surgery was zero. Most centres (96%) screened patients for symptoms prior to admission, only 22% routinely tested for SARS-CoV-2 prior to admission. The SARS-CoV-2 complication rate was 0.18% (2 pneumonias) and the overall complication rate was 6.6% (72 patients). Both SARS-CoV-2-related complications occurred in patients who had been hospitalised for a prolonged period before their surgery and a total of 19 patients (1.7%) were SARS-CoV-2 positive.

Conclusions

The SARS-CoV-2-related complication rate for upper limb surgery even at the peak of the UK pandemic was low at 0.18% and the mortality was zero for patients admitted on the day of surgery. Urgent surgery should not be delayed pending the results of SARS-CoV-2 testing. Routine SARS-CoV-2 testing for day case upper limb surgery not requiring general anaesthesia may be excessive and have unintended negative impacts.

Missing Data in the National Surgical Quality Improvement Program Database: How Does It Affect the Identification of Risk Factors for Shoulder Surgery Complications?

PURPOSE

The main purpose of this study was to establish whether different approaches to handling missingness affect the determination of risk factors associated with 30-day postoperative major and minor complications. A secondary purpose was to determine the frequency of missingness in the National Surgical Quality Improvement Program (NSQIP) records of patients who underwent shoulder surgery.

METHODS

We queried the American College of Surgeons NSQIP database using Current Procedural Terminology codes to identify patients who underwent shoulder surgery from 2011 to 2016 (n = 61,963). Data on major and minor postoperative complications were extracted. We also extracted data on patient characteristics, comorbidities, American Society of Anesthesiologists classifications, and preoperative laboratory values. We calculated the percentages of missingness for each variable. Each variable was then evaluated for associations with major and minor complications by using multivariable regression and 4 methods of handling missingness (involving imputation or exclusion, depending on the completeness of the data set). For 10 variables, the method using no exclusion or imputation produced higher odds of major complications compared with imputation. For 5 variables, the method using no exclusion or imputation produced higher odds of minor complications compared with imputation.

RESULTS

Only 6.5% of all patients had no missing data (n = 4,042), whereas 44% had <10% missingness (n = 27,165). Fewer variables were associated with both major and minor complications after shoulder surgery when patient records with missing data were excluded from analysis.

CONCLUSIONS

Different methods of handling missingness produced different odds ratios for some variables when determining risk factors for complications after shoulder surgery.

Surgical Site Infection After Open Upper Extremity Fracture and the Effect of Urgent Operative Intervention

OBJECTIVES

To identify which factors are predictive of surgical site infection in upper extremity fractures, and to assess whether the timing of operative debridement influences infection risk.

DESIGN

Retrospective database review.

SETTING

Hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database.

PATIENTS

Patients in the NSQIP database with fractures involving the upper extremity.

INTERVENTION

Surgical management of upper extremity fracture, including operative debridement for open injuries.

MAIN OUTCOME MEASUREMENTS

Surgical site infection, including both superficial and deep infections.

RESULTS

A total of 22,578 patients were identified, including 1298 patients with open injuries (5.7% of total). The overall wound infection rate was 0.79%. Patients with open injuries were found to have a higher incidence of infection compared with those with closed injuries (1.7% vs. 0.7%, P < 0.001). Independent risk factors for 30-day infection included open fracture diagnosis, obesity, smoking, and American Society of Anesthesiolgists class >2 (all P < 0.05). Of patients with open fractures, 79.7% were taken expediently to the operating room. The rate of infection did not differ based on whether surgery was performed expediently or not (1.8% vs. 1.1%, P = 0.431).

CONCLUSIONS

Based on an analysis of the NSQIP database, the overall risk of surgical site infection following intervention for open or closed upper extremity fractures remains low. Risk factors for infection include open injury, obesity, and cigarette smoking. There was no difference in the infection rate based on the urgency of operative debridement.

Epidemiology of hand fractures at a tertiary care setting in Saudi Arabia

Objectives:

To examine the epidemiology of hand fractures including common bones affected, causes, interventions, outcomes, and complications.

Methods:

This retrospective records-based study included patients who were admitted to King Saud Medical City, Riyadh, Kingdom of Saudi Arabia, with traumatic metacarpal or phalangeal fractures between January 2016 and September 2017. Carpal fractures, wrist fractures, and all pathological fractures were excluded.

Results:

A total of 82 patients (90.2% of them men with an average age of 27.6±13.4 years) with 101 fractures were included. The fifth (25.5%) and first (24.5%) rays were the most commonly affected ones. The fifth finger (27.8%) and first metacarpal (28.9%) were the most commonly affected finger and metacarpal bone. Approximately 32.7% of the fractures were open fractures. The most frequent causes of hand fractures included falls (40.5%), road traffic accidents (20.3%), crushing injuries (9.5%), and machinery injuries (9.5%). Approximately 90.1% of the patients underwent operative interventions including open reduction (50.5%) and closed reduction (34.3%). The majority of fractures (79.2%) healed, and only 14.7% of fractures developed complications.

Conclusion:

In this study of hand fractures, patients were predominantly males and the main causes of fractures were falls and road traffic accidents.
