Clavicle fractures: Associated trauma and morbidity

Hydropneumothorax in an Isolated Midshaft Clavicle Fracture

Background

Clavicle fractures are the fourth most common fracture. These fractures are either managed conservatively or surgically. Pneumothorax is a rare complication of clavicle fractures and potentially can be missed if this rare complication is not known.

Case Report

A 76-year-old female presents with a 2-day history of pain and bruising over the right clavicular prominence following a fall from a standing height. Subsequent radiographs show the development of pneumothorax, despite having no respiratory symptoms.

Discussion

Pneumothorax as a complication of isolated clavicle fractures is rare, with no case reports of hydropneumothorax in the literature. We hypothesize that the posterior displacement of the clavicle fragment penetrated the lung pleura resulting in the pneumothorax. We propose routine chest radiographs for patients presenting with clavicle fractures to rule out pneumothorax for the three reasons below. (1) Clinical features of pneumothorax might not be present upon patient's initial presentation, especially if they are relatively healthy individuals(2) Adequate pre-operative management if the patient is for surgical intervention (3) Assessment of surgical complications if the patient is for surgical intervention as iatrogenic pneumothorax is a potential complication of surgical fixation.

Conclusion

Thorough clinical examination and radiological evaluation should be performed with the diagnosis of pneumothorax in mind when a patient presents with a clavicle fracture to ensure early diagnosis and treatment of this life-threatening complication.

A 65-Year-Old Female with Missed Open Clavicle Fracture and Subsequent Fracture-Related Infection, Treated with Distal Clavicle Resection

Introduction

Open clavicle fractures are rare, and there are no current reported cases in the literature of a missed open clavicle with resultant fracture-related infection and osteomyelitis.

Case Report

We present a 65-year-old female with no reported medical history, who presented to our institution with left clavicular pain and wound drainage 8 days after she was struck by a motor vehicle in her home country of Guyana. She was found to have a missed open clavicle fracture with an associated severe infection. She was subsequently treated with irrigation, debridement, and distal clavicle excision.

Conclusion

We present this unique case with a potential procedure which could prove beneficial in cases of infection, trauma, or oncologic lesions in which the distal clavicle is deemed unsalvageable.

Efficacy of intramedullary bridge fixation for midshaft clavicle fractures: a retrospective analysis of a novel technique

BACKGROUND

The aim of this study was to explore the efficacy of a novel intramedullary fixation technique using the ortho-bridge system (OBS) for midshaft clavicle fractures.

METHODS

A total of 63 patients were included in this study: 35 underwent plate internal fixation (LP group) and 28 underwent OBS intramedullary fixation (OBS group). Surgical time, intraoperative blood loss, incision length, fracture healing time, removal of the internal fixation agent, visual analog scale (VAS) score for shoulder pain, Constant-Murley shoulder score and complication occurrence were compared between the two groups.

RESULTS

Preoperative general data, such as sex, age and fracture type, were not significantly different between the two groups (P > 0.05). However, the OBS group exhibited better outcomes than the LP group exhibited in terms of surgical time, intraoperative blood loss and total incision length (P < 0.05). Additionally, the OBS group exhibited a significantly shorter fracture healing time and internal-fixation removal time than the LP group exhibited (P < 0.05). The VAS scores on postoperative day 1, week 1, month 1 and month 3 were lower in the OBS group than in the LP group (P < 0.05). Furthermore, the Constant-Murley shoulder scores at 1, 3, and 6 months postoperatively were higher in the OBS group than in the LP group (P < 0.05), with no significant difference at 1 year after surgery (P > 0.05). None of the patients in the OBS group experienced scarring of the surgical incision, and 6 patients in the LP group experienced scarring of the surgical incision. Finally, the complication incidence in the OBS group was lower than that in the LP group.

CONCLUSION

For midshaft clavicle fractures, OBS intramedullary fixation is better than locking-plate internal fixation because it led to less trauma, a faster recovery, better efficacy, and better esthetic outcomes and comfort. Therefore, this technique may have potential as a novel treatment for midshaft clavicle fractures.

Pneumothorax After Superior Plating of Clavicle Fractures: Are the Concerns Warranted?

PURPOSE

The primary goal of this study was to determine the anatomic relationship between the clavicle and the apical lung segment. The secondary goal was to determine the incidence of pneumothorax (PTX) in patients who underwent clavicle ORIF to analyze the utility of postoperative chest radiographs.

METHODS

Six hundred thirty-one patients with a midshaft clavicle fracture who underwent superior plating at a single institution were identified. Forty-two patients had a CT scan of the chest. Three points on the uninjured clavicle were defined: 2 cm from the medial end of the clavicle, the mid-point of the clavicle, and 2 cm from the lateral end of the clavicle. At each point, the distance from both the inferior cortex and the superior cortex of the clavicle to the apical lung segment was measured. All 631 patients who underwent Open Reduction and Internal Fixation had a postoperative chest radiograph to evaluate implant placement, restoration of clavicular length, and presence of PTX.

RESULTS

From the lateral end of the clavicle, the mean distance of the lung was 60.0 ± 14.9 mm (20.1 to 96.1 mm) from the inferior cortex of the clavicle. At the mid-point, the mean distance of the lung was 32.3 ± 7.2 mm (20.4 to 45.5 mm) from the inferior cortex of the clavicle. At the medial end, the mean distance of the lung was 18.0 ± 5.5 mm (8.1 to 28.9 mm) from the inferior cortex of the clavicle. A review of postoperative radiographs for all 631 patients revealed none (0%) with a postoperative iatrogenic PTX.

CONCLUSION

The risk of injury is minimal in all three zones. Postoperative chest radiographs after clavicle fracture repair to rule out PTX are unnecessary.

Efficacy Comparison Between Interscalene Block with and Without Superficial Cervical Plexus Block for Anesthesia in Clavicle Surgery

Background

Clavicle fractures account for over one-third of shoulder injuries and up to 3.3% of all fractures in adults. While the majority of these fractures can be managed non-surgically, there are instances where surgical intervention is performed. Regional anesthesia (RA) can be a preferred alternative to general anesthesia (GA) to avoid complications and high costs in this surgery. Moreover, the identification of the most optimal approach for RA remains challenging.

Objectives

This study aimed to compare the efficacy of interscalene block (ISB) with and without superficial cervical plexus block (SCPB) as an anesthetic technique for clavicular fracture operation.

Methods

This double-blinded, non-inferiority clinical trial was conducted on 120 patients randomly divided into 2 groups: One receiving ISB and the other receiving ISB with SCPB. The primary outcome was defined as the conversion to GA. Various factors were recorded, including surgery duration, nerve block initiation, analgesics required in the postanesthesia care unit (PACU), and sedation during surgery. Pain was evaluated using the Visual Analog Scale (VAS) in PACU. SPSS version 26 was used for statistical analysis, performing descriptive analysis, Student's t-tests, and Mann-Whitney U tests to compare non-parametric variables between the 2 groups. Statistically significant results had a P value of less than 0.05.

Results

A total of 120 patients were randomly divided into 2 equal groups, each consisting of 50 males and 10 females. The mean age of intervention and case groups were 37.23 ± 13.30 and 38.43 ± 11.95 years, respectively. After performing statistical tests (Student's t-test and Mann-Whitney U test), there was no significant difference in the initiation time of nerve block, surgery initiation time, surgery duration, the amount of required sedation, VAS scores, and meperidine consumption (P > 0.05). None of the patients in both groups required conversion to GA.

Conclusions

The primary goal was achieved in all included cases, and no patients required conversion to GA. The efficacy of ISB is the same whether or not it is combined with a SCPB. Interscalene block is an alternative RA approach for clavicle fractures. Thus, ISB alone is as efficient as when used in combination with SCPB.

[Clavicle fractures: practical approach in clinical routine]

Fractures of the clavicle are among the most common fractures. They typically result from a fall onto the lateral shoulder or the extended arm and are often related to sports and bicycle accidents. Obtaining the exact trauma mechanism, proper clinical findings and adequate X‑rays usually lead to the correct diagnosis. Non-displacement fractures can be treated conservatively with good results. Unstable and displaced fractures should be treated operatively. Open fractures or looming penetration are emergencies und should be treated immediately. In addition to fracture classification and morphology, other factors such as additional injuries and patient-related factors need to be considered in order to make an individualized therapy decision. In operative treatment, angular stable plating is the therapy of choice, and in most cases early functional aftercare is possible.

Utility of routine postoperative chest radiography in patients undergoing clavicle fixation: a retrospective chart review

BACKGROUND

Although uncommon, pneumothorax is a potentially serious complication following open reduction and internal fixation (ORIF) of clavicle fractures. In many centres it is routine practice to obtain postoperative chest radiographs following ORIF of clavicle fractures to assess for iatrogenic pneumothorax. Given the need to contain health care costs, the low sensitivity for detecting small pneumothorax and a desire to decrease patient radiation exposure, the practice of ordering chest radiographs following ORIF of clavicle fractures may be unnecessary.

METHODS

All patients undergoing ORIF of clavicle fractures with plate and screw fixation at Kingston Health Sciences Centre between April 2009 and June 2020 were identified from the Discharge Abstract Database (inpatient) and National Ambulatory Care Reporting System (outpatient) using relevant Canadian Classification of Health Intervention procedure codes. Charts were manually reviewed to confirm diagnosis and procedure, and patients with preoperative pneumothorax were excluded. The frequency of postoperative chest radiograph and pneumothorax detection were calculated.

RESULTS

Among the 292 patients who underwent ORIF of clavicle fractures during the study period, 17 were excluded for having a pneumothorax on preoperative chest radiograph. Of the remaining 275 patients, 101 (36.7%) had postoperative chest radiographs, of whom none were found to have postoperative iatrogenic pneumothorax.

CONCLUSION

Since 2009, the rate of routine postoperative chest radiography following ORIF of clavicle fractures is 36.7% at our centre. During this time period, none of the 101 patients who had postoperative chest radiographs had a postoperative iatrogenic pneumothorax. To our knowledge, this is the largest series of patients available, and our findings confirm those of several smaller studies. Owing to the low rate of postoperative iatrogenic pneumothorax, we conclude that postoperative chest radiography is unnecessary following ORIF of clavicle fractures.

An Institutional Standardised Protocol for the Treatment of Acute Displaced Midshaft Clavicle Fractures (ADMCFs): Conservative or Surgical Management for Active Patients?

BACKGROUND AND OBJECTIVES

The treatment of acute displaced midshaft clavicle fractures (ADMCFs) is still under debate. The aim of this study was to verify the effectiveness of our institutional protocol by comparing the clinical and radiographic outcomes of two groups of patients with ADMCFs treated operatively and non-operatively.

MATERIALS AND METHODS

active patients with a traumatic, isolated non-pathological ADMCF with at least 1-year clinical and radiographic follow up were included. Surgical treatment was performed in the cases where the residual displacement was higher than 140% after the application of a figure-of-eight bandage (F8-B). All other cases were treated conservatively with a F8-B. A total of 134 patients were enrolled and divided into two groups: surgical and conservative groups, with 59 and 75 patients, respectively. Radiological and clinical parameters were evaluated.

RESULTS

Good clinical (Constant-Murley Score, the Quick Disability of the Arm, Shoulder and Hand score, and VAS satisfaction) and radiographic outcomes (initial and residual shortening, initial and residual displacement) were obtained for ADMCFs in both groups. Multivariate analysis showed that patients treated conservatively had better clinical outcomes compared to surgically treated patients (p < 0.001). Return to sports was longer in those treated with surgery. Initial shortening was found to impact clinical outcomes as well as initial displacement. None of the patients showed signs of non-union in both groups.

CONCLUSIONS

Very good mid-term clinical results can be obtained in adult patients with ADMCFs, conservatively or operatively managed, by applying our institutional treatment protocol based on objective radiographic parameters evaluated in the ER.

Thoracic trauma: Clinical and paleopathological perspectives

OBJECTIVES

Although trauma is one of the most significant areas of study in paleopathology, most studies focus on fractures of single anatomical elements. Paleopathological research on regional trauma, such as of the thorax, is rare. This paper explores the causes, complications, and consequences of adult thoracic trauma using clinical data in order to inform paleopathological research.

MATERIALS AND METHODS

Trends in paleopathological thoracic trauma literature were assessed by evaluating publications from Bioarchaeology International, International Journal of Osteoarchaeology, International Journal of Paleopathology, and American Journal of Biological Anthropology. Clinical publications on thoracic trauma throughout time were also assessed through a PubMed search, and modern prevalence data was found through trauma databases such as the National Trauma Databank.

RESULTS

Consideration of thoracic trauma involving concomitant injuries is a recent trend in clinical literature and patient care, but paleopathological research on thoracic trauma has been limited. Since thoracic fractures tend to occur in conjunction with other injuries, assessing them together is critical to the interpretation of trauma in the past.

CONCLUSIONS

Clinical research into thoracic fractures and concomitant injuries provides valuable data for paleopathological research. Evaluating the likelihood and consequences of concomitant injury in skeletal remains provides a more robust understanding of trauma in the past and its impact on past lifeways.

SIGNIFICANCE

This paper provides a review of current clinical and paleopathological literature on thoracic trauma and demonstrates the importance of moving beyond the analysis of fractures or trauma of single anatomical elements.

LIMITATIONS

Thoracic bones are often taphonomically altered and differentially preserved leading to difficulty in identifying and interpreting fractures.

SUGGESTIONS FOR FURTHER RESEARCH

Practical application of the data presented here to archaeological samples will help to advance paleopathological understandings of thoracic trauma.

Management of Displaced Midshaft Clavicle Fractures with Figure-of-Eight Bandage: The Impact of Residual Shortening on Shoulder Function

The treatment of displaced midshaft clavicle fractures (MCFs) is still controversial. The aims of our study were to evaluate clinical and radiological outcomes and complications of patients with displaced MCFs managed nonoperatively and to identify potential predictive factors of worse clinical outcomes. Seventy-five patients with displaced MCFs were enrolled and treated nonoperatively with a figure-of-eight bandage (F8-B). Initial shortening (IS) and displacement (ID) of fragments were radiographically evaluated at the time of diagnosis and immediately after F8-B application by residual shortening (RS) and displacement (RD). The clavicle shortening ratio was evaluated clinically at last follow-up. Functional outcomes were assessed using Constant (CS), q-DASH, DASH work and DASH sport scores. Cosmetic outcomes and rate of complications were evaluated. Good to very good mid-term clinical results were achieved by using the institutional treatment protocol. Multiple regression identified RS as an independent predictor of shoulder function, while RD affects fracture healing. These findings support the efficacy of our institutional protocol and thus could be useful for orthopedic surgeons during the decision-making process.

A Thoracic Outlet Syndrome That Concealed a Glioblastoma. Findings from a Case Report

Background: Glioblastoma is the most frequent and aggressive malignant brain tumor among adults. Unfortunately, its symptoms can vary considerably depending on the size, location and the anatomic structures of the involved brain. Case report: A 58-year-old male amateur cyclist who suffered from sharp arm pain was examined for a thoracic outlet syndrome due to a previous clavicle fracture. Because of ambiguous results of the neck and nerve plexus imaging, he was referred to a neurosurgeon who properly suspected a brain tumor. The neuroimaging of the brain shown a 3 cm disploriferative mass with a blood enhancement within the left parietal lobe. The mass was urgently removed, and its histologic analysis stated a grade 4 glioblastoma. Conclusion: This case report highlights the differential diagnosis process and the teamwork approach needed to diagnose a rare presentation of a brain glioblastoma, which started its symptoms mimicking a thoracic outlet syndrome caused by a previous bone fracture.

COVID-19 Changed the Incidence and the Pattern of Pediatric Traumas: A Single-Centre Study in a Pediatric Emergency Department

The first wave of COVID-19 spread worldwide from March to May 2020. Italy was one of the countries in the world where the lockdown period was most prolonged and restrictive. To date, the impact of prolonged lockdown on pediatric traumas has not fully investigated. This paper aimed to analyze, and compare to 2019, the incidence and the fracture pattern in patients admitted to our pediatric hospital during the total lockdown period. A single-center retrospective study was performed. The data were gathered from the Pediatric Emergency Department (PED) of the Bambino Gesù Children Hospital of Rome (Palidoro). This PED is the pediatric referral center for Rome and the hub for pediatric traumas of the region. Any admission diagnosis for fracture, trauma, sprains and dislocation during the lockdown period (10 March-4 May) were included. The demographic data, diagnosis, type of treatment, fracture segment, bone involvement and time interval between trauma and presentation to the PED were recorded. In 2020, a reduction of total traumas and fractures, compared to 2019 (p < 0.001), occurred (81%). Superior limb and inferior limb fractures decreased in 2020 compared to 2019 (p < 0.05). The identification of pediatric traumas and fractures trend could be useful to reorganize the PED. Epidemiological data from the previous lockdown could be helpful to prepare the healthcare system for new pandemic waves. Moreover, sharing national statistics and correlating those to other countries' protocols, could be helpful to solve problems in case of worldwide emergency situations.
