Posteromedial elbow dislocation with lateral humeral condyle fracture in children: How to manage? Case report and review of the literature.

Posteromedial dislocation of the elbow is a rare entity even exceptional if associated with a lateral condylar fracture. Very few isolated cases are reported in the English literature. We report an additional case of a 14-year-old child admitted for elbow trauma during scholar sport and presented a posteromedial elbow dislocation associated with a fracture of the lateral humeral condyle. The surgical treatment was made by using 3 cortical screws. The results were satisfying including range motion and he has resumed sports activities at 5 months. Elbow dislocation is a rare affection in children. It represents 3% to 6% of elbow injuries. The association of posteromedial elbow dislocation with a Milch type I is remarkably rare. We review the mechanism, classifications, and therapeutic modalities of this injury. Elbow dislocations associated with a lateral condylar fracture are exceptional and need an early reduction followed by an anatomical internal fixation to ensure articular congruity.

Efficacy of Direct Versus Peripheral Adjuvant Dexamethasone on Duration and Rebound Pain in Regional Anesthesia for Outpatient Distal Radius Fracture Fixation: A Prospective Randomized Controlled Blinded Study.

BACKGROUND: Despite increasingly wider use, there remains controversy among anesthesiologists regarding preferred formulations and the role of steroid adjuvants in regional anesthesia. There is also uncertainty in the role of dexamethasone when administered directly versus peripherally. We hypothesize that directly mixing dexamethasone into the regional nerve block rather than peripherally administered intravenous dexamethasone will demonstrate a difference in efficacy concerning duration and rebound pain, decreased postoperative pain scores, or opioid consumption within the short-term postoperative period. METHODS: A prospective, randomized controlled blinded study was conducted for patients undergoing open reduction and internal fixation with a volar plate technique for distal radius fractures. Patients were randomized for their preoperative anesthesia. One group had ultrasound-guided supraclavicular block with ropivacaine with a direct mix of dexamethasone 4 mg (Direct group), while the other group had ultrasound-guided supraclavicular block with ropivacaine and peripheral intravenous dexamethasone 4 mg (Indirect group). Data was collected pre, intra, and postoperatively. RESULTS: Fifty patients consented and participated in the study, with 27 participants in the direct group and 23 participants in the indirect group. Compared to intravenous administration, directly administered dexamethasone demonstrated a significant difference in the average time for the block to fade, onset of motor and sensory recovery, and block resolution. CONCLUSION: Our findings prove that directly mixing dexamethasone compared to peripherally administered intravenous dexamethasone will demonstrate a difference in efficacy with regards to duration and rebound pain, but do not prove that there will be a difference in decreased postoperative pain scores or opioid consumption within the 24-hour postoperative period. LEVEL OF EVIDENCE: Prognosis Level I.

Bilateral Pronation Type Galeazzi Fracture Dislocation.

The Galeazzi fracture dislocation, an uncommon forearm fracture in adults, becomes even rarer when occurring bilaterally, with limited studies documenting this condition. Here, we report the case of a 57-year-old female who presented to our emergency room with bilateral Galeazzi fracture dislocations. The patient underwent bilateral open reduction and internal fixation of the radial fractures, along with stabilization of the distal radioulnar joints. Follow-up monitoring over 16 months postoperatively showed positive outcomes without complications.

Evaluation of chronic perilunate dislocations: A comparative study of single-stage, two-stage ORIF, and salvage procedures.

OBJECTIVE: This study aims to evaluate the outcomes of open reduction and internal fixation (ORIF) for chronic perilunate dislocations using single-stage, two-stage, and salvage procedures. The study also compares these approaches with each other and with results from existing literature. METHODS: A total of 15 patients with chronic perilunate injuries from 2013 to 2019 were included in the study. Pre-operative and post-operative assessments were conducted using plain radiographs, with CT scans performed selectively for detailed morphology and fracture pattern analysis. Among the patients, 13 underwent ORIF, while 2 underwent salvage procedures. Among the ORIF cases, single-stage procedures were performed in 4 patients, and two-stage procedures in 9 patients. External fixators, including unilateral uniplanar external fixators (UUEF) and bilateral uniplanar external fixators (BUEF), were applied in 5 and 4 patients, respectively. Our methodology of treating chronic perilunate injuries has evolved over the years. We started with single stage ORIF then graduated to a two staged procedure initially using a external fixator as a carpal distractor applied only on the radial side and finally settling down with bilateral carpal distraction using external fixators both on the radial and ulnar sides. RESULTS: Among the 15 patients, 3 were lost to follow-up. Of these, one underwent four-corner fusion, while the remaining two had UUEF. The mean time interval between injury and surgery was 3.60 months. The post-operative mean scapholunate angle measured 52.46°, with a negative radio-lunate angle (indicating flexion) observed in two patients, while others showed a positive angle (indicating extension). Two cases exhibited nonunion and avascular necrosis (AVN) of the scaphoid, while one case presented with lunate AVN. Mid-carpal and radio-carpal arthritis was observed in 4 and 2 patients, respectively. Functional outcomes were evaluated using Mayo's wrist score categorized as good for two-stage BUEF cases and satisfactory for UUEF and single-stage procedures. CONCLUSION: Staged reduction utilizing the BUEF followed by open reduction has demonstrated superior outcomes when compared to UUEF, single-stage open reduction and salvage procedures. LEVEL OF EVIDENCE: 4.

Prone position fibula nail and tibia buttress plate for large Volkmann fracture-dislocations technical note and preliminary results on a short case series.

Large posterolateral tibial fragments, known as Volkmann fractures, are common in ankle fracture-dislocations and typically require open reduction and fixation with interfragmentary screws and often buttress plates using a prone posterolateral approach. In this setting, fibula plating often necessitates dissection of the lateral window between the peroneal tendons and the skin, increasing wound-related complications. In recent years, intramedullary nailing of fibula fractures has gained popularity as a minimally invasive technique that allows load-sharing stabilization. However, this procedure has traditionally been performed in the supine position, which can pose challenges if a Volkmann-type fracture is present, requiring repositioning and losing access to the fibula through the posterolateral approach. Our objective is to describe a technique for fixing ankle fracture-dislocations with large posterolateral fragments using tibial buttress plates and fibula nails through a prone posterolateral approach without dissecting the lateral window. Additionally, we will present a case series with preliminary results.

The Power of Movement: A Comprehensive Case Study of Physiotherapeutic Approaches in Electrical Injury Rehabilitation.

Electrical injuries are common phenomena in developing countries, due to inadequate safety measures followed during day-to-day electrical repairs. Workplace injuries account for 20% of these. In some severe cases, electrical injuries lead to burns, indirect fracture dislocations, speech impairments, etc. Falls due to electrical injuries leading to secondary complications are very common and, even though not very severe, they do require immediate treatment and adequate rehabilitation. A 53-year-old male suffered a shoulder injury following an electrical shock. The patient also experienced irritation and speech disturbances. Examination revealed a reduced range of shoulder joints and tightness of muscles of the shoulder complex. Physiotherapy intervention included counseling for the patient and his family members, energy conservation methods for ease in daily activities, a rehabilitation protocol, and modified music therapy. Outcome measures used to assess the progression constituted the Shoulder Pain and Disability Index (SPADI), the Tampa Scale for Kinesiophobia (TSK), and the Depression and Anxiety and Stress Scale. Rehabilitation with adjunct therapy is effective in the overall improvement of the patient's condition concerning their mental health as well as physical health by early strength training.

Three-Dimensional Quantitative Study and Functional Outcome Analysis of Coronoid Fracture in Different Elbow Injury Patterns.

BACKGROUND: Coronoid fractures are often part of a complex fracture-dislocation of the elbow. For an optimum prognosis, it is important to understand the characteristics of coronoid fractures in different elbow injury patterns. Significant differences in these characteristics have been observed in various studies, but these previous studies have suffered from limitations, such as insufficient quantification and unknown prognostic differences among different injury patterns. Therefore, we aimed to quantitatively analyze coronoid fracture characteristics and functional outcomes in different elbow injury patterns using 3D-CT. METHODS: All patients with coronoid fractures surgically treated at our hospital between January and December 2017 were categorized into three groups according to elbow injury pattern: PLRI, VPMRI and OFD. 3D models were reconstructed using Mimics 17.0, and the total volume (TV) and number of coronoid fragments (NCF) were measured. The coronoid process edge was classified into different anatomical regions, and each region was assigned a number to quantify the distribution of fracture lines. At the last follow-up, the ROM, VAS, MEPS, complications and reoperations were recorded. RESULTS: The ninety-two patients enrolled had an average age of 42±15 years and a male-to-female ratio of 66:26. The median TV in PLRI patients was less than that in VPMRI patients [431 (132, 818)mm3 vs. 1125 (746,1421)mm3,adjusted P<0.001] and OFD patients [431 (132, 818) mm3 vs. 2565 (381, 4076)mm3, adjusted P =0.001]. The median NCF in PLRI patients was also less than that in VPMRI patients [1 (1, 2) vs. 2 (1, 3), adjusted P=0.043]. Most of the PCFL-Rs (79%) were located around the volar edge of the lesser sigmoid notch. Compared with that of PLRI, the PCFL-Us of the VPMRI and OFD tended to be located on the more ulnodorsal side of the coronoid process edge. The median ROM [110 (90, 133), P=0.001] and the median MEPS [85 (68, 95), P=0.038] of patients with OFD were significantly less than those of patients with the other two patterns. The incidence of elbow stiffness (56%, 5/9, P=0.001) and implant-related irritation (44%, 4/9, P<0.001) in the OFD group was significantly higher than that in the other two groups. CONCLUSION: Coronoid fractures differ significantly in fragment volume, comminution severity and fracture line distribution among different elbow injury patterns. OFD has the worst functional outcomes among complex elbow injury patterns.

Hounsfield units in assessing bone mineral density in ankylosing spondylitis patients with cervical fracture-dislocation.

BACKGROUND: Cervical spine fracture-dislocations in patients with ankylosing spondylitis (AS) are mostly unstable and require surgery. However, osteoporosis, one of the comorbidities for AS, could lead to detrimental prognoses. There are few accurate assessments of bone mineral density in AS patients. AIM: To analyze Hounsfield units (HUs) for assessing bone mineral density in AS patients with cervical fracture-dislocation. METHODS: The HUs from C2 to C7 of 51 patients obtained from computed tomography (CT) scans and three-dimensional reconstruction of the cervical spine were independently assessed by two trained spinal surgeons and statistically analyzed. Inter-reader reliability and agreement were assessed by interclass correlation coefficient. RESULTS: The HUs decreased gradually from C2 to C7. The mean values of the left and right levels were significantly higher than those in the middle. Among the 51 patients, 25 patients (49.02%) may be diagnosed with osteoporosis, and 16 patients (31.37%) may be diagnosed with osteopenia. CONCLUSION: The HUs obtained by cervical spine CT are feasible for assessing bone mineral density with excellent agreement in AS patients with cervical fracture-dislocation.

Management of greater tuberosity fracture dislocations of the shoulder.

Background: Despite extensive literature dedicated to determining the optimal treatment of isolated greater tuberosity (GT) fractures, there have been few studies to guide the management of GT fracture dislocations. The purpose of this review was to highlight the relevant literature pertaining to all aspects of GT fracture dislocation evaluation and treatment. Methods: A narrative review of the literature was performed. Results: During glenohumeral reduction, an iatrogenic humeral neck fracture may occur due to the presence of an occult neck fracture or forceful reduction attempts with inadequate muscle relaxation. Minimally displaced GT fragments after shoulder reduction can be successfully treated nonoperatively, but close follow-up is needed to monitor for secondary displacement of the fracture. Surgery is indicated for fractures with >5 mm displacement to minimize the risk of subacromial impingement and altered rotator cuff biomechanics. Multiple surgical techniques have been described and include both open and arthroscopic approaches. Strategies for repair include the use of transosseous sutures, suture anchors, tension bands, screws, and plates. Good-to-excellent radiographic and clinical outcomes can be achieved with appropriate treatment. Conclusions: GT fracture dislocations of the proximal humerus represent a separate entity from their isolated fracture counterparts in their evaluation and treatment. The decision to employ a certain strategy should depend on fracture morphology and comminution, bone quality, and displacement.

Successful closed reduction of Bosworth ankle fracture-dislocation: A case report.

Bosworth fracture-dislocation presents a challenge in ankle joint injuries owing to its irreducible nature, requiring open reduction in most cases. Reports on successful outcomes following closed reduction are limited, necessitating exploration into alternative treatment approaches. Herein, we report a case of Bosworth fracture-dislocation in a 39-year-old man, with radiographic evidence of posterior displacement of the distal portion of the proximal fibular fragment incarcerated behind the tibia. Closed reduction was attempted with the patient's knee flexed at 90°, employing gradual traction, internal foot rotation, and counterforce provided by an assistant. The procedure resulted in a successful reduction, highlighting the potential of closed reduction in managing Bosworth fracture-dislocations. This underscores the importance of considering closed reduction as an initial treatment option before surgery, particularly given the injury mechanism. However, repeated attempts for closed reduction should be avoided to prevent iatrogenic soft tissue damage, which could result in postoperative wound complications and compartment syndrome. This case demonstrates the feasibility of closed reduction in Bosworth fracture-dislocation cases, offering a potential avenue to delay surgical intervention until the resolution of limb swelling and improve patient outcomes.

Anterior Sacroiliac Fracture Dislocation: A Comparative Radiologic analysis of Crescent Fractures in Pelvic Ring Injuries: A Retrospective Study.

Background and Objectives: Anterior sacroiliac fracture dislocation (ASFD), also known as locked pelvis, is a rarely reported diagnosis. The types of ASFDs are often misdiagnosed as lateral compression fractures due to the presence of crescent fractures. In this study, we distinguished ASFD from lateral compression fractures (LC 2) and studied their characteristics. Materials and Methods: This is a retrospective study involving patients from a Level 1 trauma center. Fifty-nine patients under the age of 65 years with crescent fractures caused by a high-energy mechanism were investigated. Results: The incidence of ASFD was 25% (15 of 59) in patients with crescent fractures. Among the 15 patients, 6 had override of the ilium over the sacrum, inhibiting reduction in the sacroiliac joint. Pre-operative radiographic evaluations revealed that vertical displacement of the ASFD was larger than that of lateral compression fracture (LC 2) in the outlet view (mean 9.5 vs. 1.9 mm, p = 0.013), and the pelvic asymmetry ratio was larger in ASFD (mean 7.8 vs. 4.1, p = 0.006) in the pelvis AP view. All patients achieved union after surgery. Post-operative radiography showed no significant vertical displacement difference. There was no difference in vascular injury or hemodynamic instability requiring embolization or preperitoneal pelvic packing (PPP) between the two groups. Conclusions: Patients with ASFD have greater vertical displacement and asymmetry compared to patients with LC 2 fractures. These fractures must be distinguished for appropriate reduction and anterior plate fixation.

Usability of Minimal Invasive Surgery for Elbow Dislocation with Coronoid Process Fracture: A Protocol Development Study.

OBJECTIVE: The study aims to explain whether or not minimal invasive surgery (MIS) would be feasible in elbow fracture-dislocation with coronoid process fracture. METHODS: At Taipei Veterans General Hospital, patients who had elbow dislocations with coronoid process fractures underwent a single surgeon's MIS techniques which included the fluoroscopy-guided ulnar anteromedial (FGUAM) approach in the stage of reducing the coronoid process. When there is a proximal ulnar fracture, the posterior incision should be necessary, followed by the incision over the lateral or medial elbow for treating radial fractures or ligament injuries. RESULTS: The Flow Diagram for approach recommendation was established on the basis of defining MIS as that which does not include cross-plane dissection. The importance of anterior rigid fixation for the coronoid process was also emphasized. CONCLUSIONS: MIS can be achieved by multiple limited surgical incisions. Although the posterior extensile approach is necessary in situations of ulnar metaphysis or ligament avulsion fracture, the FGUAM approach decreases the cross-plane dissection.

Effects of early surgery for cervical fracture dislocation on 30-day mortality using the Japanese Diagnosis Procedure Combination database.

STUDY DESIGN: Retrospective study of data abstracted from the Diagnosis Procedure Combination (DPC) database. PURPOSE: This study aimed to investigate the effects of surgery in the early phase. OVERVIEW OF LITERATURE: The optimal timing of surgery for cervical fracture dislocation (CFD) remains unclear because only a few clinical studies with approximately 100 patients have been published. METHODS: This study included 4,653 adult patients with a definitive diagnosis of CFD from the DPC database. The database contains nationwide inpatient data collected from >1,000 acute care hospitals in Japan. The DPC database contains information regarding hospitalization, such as diagnosis, treatment, medical history, complications, and hospitalization outcomes. This study identified 460 pairs of patients after one-to-one propensity-score matching (PSM). Treatment outcomes were compared between patients who underwent surgery for CFD within 72 hours (early group) and later (delayed group) after admission. The main outcomes included 30-day mortality, inhospital death, and major complications. The secondary outcomes were improvement in the Barthel index, length of hospital stay, and discharged home rate. RESULTS: After adjusting for PSM, the early group had a significantly higher 30-day mortality rates than the delayed group (3.0% vs. 0.4%, p=0.006). In the multivariate logistic regression analysis after PSM, the early group was associated with an increased risk of 30-day mortality (odds ratio, 8.05; 95% confidence interval, 2.15-5.26; p=0.007). CONCLUSIONS: This study indicated that early surgery for CFD resulted in increased 30-day mortality.

Evaluation of Monteggia Fracture Outcomes: Acute to Chronic.

INTRODUCTION: Our study aims to characterize the results of Monteggia fractures treated in our practice and to determine factors associated with good or poor outcomes. METHODS: A retrospective review of children aged 17 and under with acute, subacute, or chronic Monteggia fractures who were treated at our institution was performed. The primary outcomes were initial reduction and maintenance of joint reduction, while the secondary outcomes were elbow flexion/extension and forearm supination/pronation. RESULTS: Seventeen patients with Monteggia fractures were identified. Two patients were excluded: 1 was lost to follow-up and 1 had congenital absence of the elbow flexors. Thus, our final cohort was 15 patients (acute n = 3, subacute n = 4, chronic group n = 8). Median final follow-up was 1.9 years (range = 34 days-8 years). CONCLUSION: Preoperative range of motion (ROM) was the most important factor in determining postoperative ROM in this cohort of patients with chronic Monteggia fractures. All patients who presented with excellent preoperative ROM, regardless of their timing category, had an excellent ROM outcome. Time from initial injury also played an important role. All patients in the acute and subacute categories had good or excellent postoperative ROM. Patients who were further from the initial injury were more likely to present with worse preoperative ROM and, in turn, had worse outcomes with postoperative ROM.

Peri-Trapezium Peri-Trapezoid Trans-scaphoid Open Fracture Dislocation of the Carpus: A Case Report.

The axial fracture dislocation of the carpal bones is a poorly understood injury. These injuries are often associated with nerve injuries, soft tissue injuries, and amputations. An optimal treatment is not yet known. We present a rare case of an open trans-scaphoid axial fracture dislocation of the carpus, characterized by a unique mechanism of injury. The patient received timely treatment, including irrigation and debridement, as well as reduction and fixation of the carpal fracture dislocation. It is essential to understand that these injuries tend to result in poor clinical outcomes, even with optimal treatment. Therefore, engaging in meaningful discussions and setting realistic expectations with patients is imperative.

Radiological characteristics and injury mechanism of Logsplitter injury: a descriptive and retrospective study.

BACKGROUND: Logsplitter Injury is a type of high-energy ankle fracture dislocation. The mechanism of injury has not been described in detail. A detailed understanding of the radiological features and pathological changes can further guide treatment. METHODS: Between April 2009 and December 2018, a retrospective analysis was conducted on 62 patients with Logsplitter injury. The study analysed the characteristics of fibular injury, tibial injury, syndesmosis injury, medial injury and lateral ligament injury on preoperative X-ray and CT scans. The incidence of the different injury types was summarised. The correlation between Logsplitter injuries and the mechanisms causing them were analysed using the Lauge-Hansen classification of ankle fractures. RESULTS: The study provides data on the types of fractures observed. Of the total fractures, 98.4% were open fractures. The fibula injuries were classified as no fracture (1.6%), transverse or short oblique fractures (61.3%), butterfly fragments (25.8%), and comminuted fractures (11.3%). The tibial injuries included compression of lateral articular surfaces (38.7%) and posterior compressions (6.5%). Medial injuries, including medial malleolar fractures, accounted for 87.1%, and deltoid ligament rupture accounted for 12.9%. The study found that injuries to the syndesmosis consisted of simple ligament ruptures (11.3%), Tillaux fractures (8.1%), Volkmann fractures (43.5%), and Tillaux and Volkmann fractures (37.1%). In 12.9% of cases, there was a complete rupture of the lateral collateral ligament. Based on the Lauge-Hansen classification, 87.1% of injuries were pronation-abduction injuries, while 8.1% were pronation and external rotation injuries, and 1.6% were supination external rotation injuries. Furthermore, 3.2% of cases could not be classified. CONCLUSION: The pathoanatomic characteristics of Logsplitter injury are diverse, with some cases accompanied by collateral ligament injury. It is important to note that these evaluations are objective and based on current results. The most common injury mechanism is vertical violence combined with abduction, although in some cases, it may be a vertical combined external-rotation injury. LEVEL OF EVIDENCE: (4) case series. TRIAL REGISTRATION: This study has been approved by the ethical research committee of the Honghui Hospital of Xi'an Jiaotong University, under the code: 202,003,002.

Morphometric Analysis of Glenopolar Angle of the Scapula in Indian Population.

BACKGROUND: The glenopolar angle (GPA), usually ranges from 30° to 45°. GPA measures the tilt of the plane of the glenoid cavity in relation to the axis of the body of the scapula passing from the superior pole of the glenoid cavity to the inferior angle of the scapula. It is essential to assess the results of surgeries for dislocated shoulders. Worse long-term outcomes can arise from glenoid misalignment in scapular neck fractures. When evaluating prognosis and planning therapy for shoulder injuries including scapular fractures, GPA assessment is essential. Still, there is a dearth of data on the normal range of GPA and its contributing elements, which calls for more study. The purpose of this study is to determine typical GPA values by utilizing radiographs and a sizable sample of scapular bone specimens. METHODS: In this study, the GPA was assessed in 50 chest radiographs of anteroposterior (AP) view and Neer's view of individuals as well as 100 dried scapulae of any gender. The mean GPA obtained using the various methods was then statistically compared. FINDINGS: All scapulae had an average GPA of 42.6°. Twenty-nine scapulae had GPA observations higher than 45°, with an average of 47.2°. Twenty-seven scapulae had GPA measurements below 40°, averaging 37.3°. Right-sided 62 scapulae with an average GPA of 43.1° were present. Thirty-eight of left-side scapulae had a GPA of 41.7° on average. It was determined that the 1.6° mean difference in GPA between the two groups was not statistically significant. The Kolmogorov-Smirnov test verified that the GPA data had a normal distribution. The homogeneity of variances across various measuring techniques was confirmed using Levene's test. The average GPA measured using the dry scapula approach was 42.6°, the average GPA measured using the AP view was 39.8°, and the average GPA measured using the Neer I view was 42.3°. The GPA means from these three approaches differed considerably (p=0.0014) according to a one-way Analysis of Variance (ANOVA). Fisher's least significant difference post hoc testing showed that the scapular bone specimens and the Neer I view revealed significantly higher GPA values than AP shoulder radiographs. The GPA values obtained from the osteological group and the Neer I perspective had a mean difference of 0.21°, which was practically identical and suggested that there was no statistically significant difference between these approaches. IN SUMMARY: In order to diagnose and treat a variety of shoulder joint diseases, this study estimates the normal values of scapular GPA. Furthermore, it offers support for improved implant design in the context of Indian shoulder joint replacement and repair. Using every measurement technique, the GPA values on the right and left sides did not differ significantly. GPA results from various measuring methods varied significantly, which emphasizes the significance of methodological consistency in clinical and research settings.

Metacarpal Stress Fractures in Athletes: A Systematic Review.

BACKGROUND: Stress fractures in general are common injuries; however, there is limited literature on metacarpal stress fractures in athletes. Our objective is to contribute the first systematic review of metacarpal stress fractures in athletes, with a particular focus on epidemiology, presentation, and outcomes. METHODS: A systematic review regarding metacarpal stress fractures in athletes was performed via PubMed, EMBASE, MedLine, Cochrane, and Web of Science. Inclusion criteria consisted of case reports and case series of metacarpal stress fractures in athletes. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. RESULTS: A total of 11 studies (29 cases) were included. The mean patient age was 17 years, with 12 men and 15 women. The most common sports were tennis and badminton. The most common presentation was pain in the dorsal aspect of the hand related to activity. All patients underwent successful nonoperative management, with mean return to play of 9 weeks. CONCLUSIONS: Metacarpal stress fractures can present with significant pain and impact performance in athletes who perform sports involving repetitive movements of the hand and wrist. Nonoperative treatment, consisting of abstinence from sport until the patient was pain free combined with gradual return to play, was successful for all patients. The addition of proper technique and training load can result in satisfactory return to play. For patients who present with hand pain related to exercise, particularly a young racquet sport player, metacarpal stress fractures are a "can't miss" diagnosis associated with significant functional impairment.

Inter-Rater and Intrarater Reliability of Radiographs in the Diagnosis of Pediatric Scaphoid Fractures.

BACKGROUND: Pediatric scaphoid fractures can be challenging to diagnose on plain radiograph. Rates of missed scaphoid fractures can be as high as 30% to 37% on initial imaging and overall sensitivity ranging from 21% to 97%. Few studies, however, have examined the reliability of radiographs in the diagnosis of scaphoid fractures, and none are specific to the pediatric population. Reliability, both between different specialists and for individual raters, may elucidate some of the diagnostic challenges. METHODS: We conducted a 2-iteration survey of pediatric orthopedic surgeons, plastic surgeons, radiologists, and emergency physicians at a tertiary children's hospital. Participants were asked to assess 10 series of pediatric wrist radiographs for evidence of scaphoid fracture. Inter-rater and intrarater reliability was calculated using the intraclass correlation coefficient of 2.1. RESULTS: Forty-two respondents were included in the first iteration analysis. Inter-rater reliability between surgeons (0.66; 95% confidence interval, 0.43-0.87), radiologists (0.76; 0.55-0.92), and emergency physicians (0.65; 0.46-0.86) was "good" to "excellent." Twenty-six respondents participated in the second iteration for intrarater reliability (0.73; 0.67-0.78). Sensitivity (0.75; 0.69-0.81) and specificity (0.78; 0.71-0.83) of wrist radiographs for diagnosing scaphoid fractures were consistent with results in other studies. CONCLUSIONS: Both inter-rater and intrarater reliability for diagnosing pediatric scaphoid fractures on radiographs was good to excellent. No significant difference was found between specialists. Plain radiographs, while useful for obvious scaphoid fractures, are unable to reliably rule out subtle fractures routinely. Our study demonstrates that poor sensitivity stems from the test itself, and not rater variability.
