Stabilization Of Fractures Research Articles

Effect of additional free sustentaculum tali screw fixation through modified sinus tarsi approach on intra-articular calcaneal fractures.

Calcaneal fractures are the most common type of tarsal fractures. The sustentaculum tali (ST) offers anatomical stability in calcaneal fractures, and recently, ST screws have been widely used in their treatment. This study aimed to investigate the clinical efficacy and value of ST screw fixation via a modified sinus tarsi approach (MSTA) for treating displaced intraarticular calcaneal fractures (DIACFs). This study enrolled 64 patients (64 feet): 32 patients in the calcaneal locking plate combined with the ST screw group (CLP-STS Group) and 32 patients in the simple calcaneal locking plate internal fixation group (CLP Group). The minimum follow-up duration was 18 months. Ankle function was evaluated using VAS, AOFAS, and Short Form-36 scores. Imaging evaluation included the Böhler angle, Gissane angle, length, height, and width of the calcaneus, and the Böhler angle in both groups 1 year after surgery. Functional evaluation revealed that postoperative AOFAS and VAS scores in the CLP-STS Group were significantly better than those in the CLP Group. After surgery, the Böhler angle, Gissane angle, and length, height, and width of the calcaneus were significantly corrected compared to the preoperative values; however, the difference in these indicators between the two groups was not significant. Nevertheless, at the 1-year postoperative follow-up, the calcaneal Böhler angle loss in the CLP-STS Group was significantly better than that in the CLP Group. Compared to simple calcaneal locking plate internal fixation, combining the plate with the additionally free ST screw can resolve the limited intraoperative exposure of MSTA, reduce postoperative foot pain in patients, and improve clinical efficacy.

Novel hook plate for radial semilunar lip facet fragment fixation: a finite element analysis.

Intra-articular fractures of the distal radius require anatomical reduction and stable fixation. When the fracture encompasses the articular facet of the bone, maintaining the reduction is challenging due to the fragment's size and high instability. While specific implants have been developed to fix this fragment, their effectives have been limited. This study evaluates the mechanical performance of a novel hook plate conceived to stabilize the small fragment of the semilunar facet of the radius in non-osteoporotic bones. A simulated lunate facet fracture was created in an adult radius in a virtual model, and a modification of a hook plate was developed using computer-aided design (CAD). Two groups were established for the finite element method (FEM) simulation: a control group (standard plate Medartis™ (Switzerland, A-5500.23) and an angled plate with hooks set at 60º, 90º and 120º. In the FEM simulation, an axial load of 100N was applied in the Z-axis direction on the fragment. Fracture displacement along the Z axis was more pronounced in the control model (0.32mm) and less in the angled models, ranging from 0.22 to 0.28mm. Notably, the plate with a 90° angle showed a more effective reduction in fragment displacement. The distribution of stresses in the system showed the highest levels of stress in the control group (59.31MPa), followed by the subgroup with a 60° angle (55.78MPa).In the side view, the control model showed a higher concentration of stresses (59.74MPa), while the model with a 90° angle showed a lower value of stresses (18.87MPa). Critical stress regions were identified in the bolts of the control and 120° models (59.47MPa and 57.64MPa, respectively). However, in the 90° model, no critical regions were observed in the bolts, which showed lower stress values, reaching 26.33MPa. In the bone, the greatest concentration of stress occurred in the region where the plate was anchored. Our results showed that the 90° hook plate had a superior mechanical performance in fixing simulate lunate facet fractures at the distal radius. This angle led to minor displacements and minimized stress concentrations in the hardware, thus contributing to enhance the stability of this specific fracture.

Congruent Weber-B ankle fractures do not alter tibiotalar contact mechanics.

Current treatment strategy for managing Weber B ankle fractures is mainly governed by mortise congruency, malleolar alignment, deltoid ligament competence and fracture stability. While nonoperative treatment has yielded good functional outcomes in satisfactorily aligned stable injuries, a biomechanical rationale is not firmly established. Furthermore, current radiographic analysis is obscured by observer inaccuracy and beam rotation. This study aimed to utilize weightbearing CT and computational biomechanics to analyse 3D mortise displacement and contact mechanics in Weber-B ankle fractures and compare them with the uninjured contralateral side. 32 patients were included who sustained a Weber-B ankle fracture and underwent bilateral weightbearing CT imaging at injury. Segmentation into 3D models of bone was performed semi-automatically, and individualized cartilage layers were modeled based on a previously validated methodology. The 3D mortise congruency was evaluated by use of following parameters: alpha angle, fibular length, talocrural angle, medial gutter- and tibiofibular clear space- distance mapping. Contact mechanics were evaluated by the mean and maximum contact stress of the tibiotalar articulation. Statistical analysis revealed that there were no significant differences for all anatomical parameters. There was also no significant difference between the mean contact stress of the injured (2.10 ± 0.42 MPa) and uninjured side (2.10 ± 0.41 MPa), nor the maximum contact stress of the injured (7.67 ± 1.55 MPa) and uninjured (7.47 ± 1.67), respectively. Contact mechanics were unaffected in congruent Weber-B fractures. These findings support consideration of nonoperative management in such cases, given their presumably low risk for posttraumatic arthritic development in the long term. Level of Evidence: Level III; retrospective case-control study.

Is partial excision of the radial head safe and effective in all-arthroscopic treatment of terrible triad fractures?

Background: Our study aimed to evaluate the clinical and radiologic results of all-arthroscopic treatment of terrible triad injuries followed-up for a minimum of 5 years and investigate how arthroscopic partial excision for radial head fractures affects the results at the final follow-up.Methods: We retrospectively reviewed consecutive patients with terrible triad injuries who underwent all-arthroscopic treatment between January 2011 and June 2018. In group I, we performed conservative or arthroscopic fixation of stable radial head fractures, while in group II, arthroscopic partial excision of unstable radial head fractures involving <30%–50% of the articular surface area was performed. Clinical outcomes were measured by visual analog scale score and assessment of instability, range of motion (ROM), and Mayo Elbow Performance Score. Radiological outcomes were evaluated using x-rays, and the integrity of the repaired lateral collateral ligament complex was confirmed through magnetic resonance imaging.Results: Thirty-two patients with an average age of 49.5±16.2 years met the inclusion criteria and were followed-up for a mean of 82.7±22.2 months. Twenty patients were assigned to group I and 12 patients to group II. Clinical outcomes showed no significant differences between the two groups at the final follow-up (P>0.05). On radiological evaluation, more heterotopic ossifications were found in the radial head excision group (group II, 66.7% versus group I, 35%, P=0.02); however, there was no significant difference in ROM between the two groups (P>0.05).Conclusions: In all-arthroscopic treatment of terrible triad injuries, arthroscopic partial excision of the radial head did not seem to have a significant impact on elbow joint stability.Level of evidence: III.

Comparative Outcomes of Percutaneous K-Wires Versus Plate Fixation in the Treatment of Distal Radius Fractures: A Focus on Stability in Osteoporotic Patients and Both-Bone Distal End Fractures.

Background Distal radius fractures (DRFs) are commonly treated with percutaneous K-wire or plate fixation. The relative efficacy and stability of these methods, particularly in osteoporotic patients and in cases involving both distal radius and ulna fractures, remain subjects of clinical debate. Objective This study aims to compare the outcomes of percutaneous K-wire fixation versus plate fixation in patients with distal end radius fractures, focusing on postoperative stability in osteoporotic conditions and both-bone distal end fractures. Methods A total of 50 patients were retrospectively analysed and divided into two groups: 25 underwent percutaneous K-wire fixation, and 25 underwent plate fixation. Outcomes measured included bone healing time, complication rates, functional recovery using the DASH score, and radiological outcomes through standard X-ray imaging. Results Preliminary data suggest that plate fixation offers better stability, especially in osteoporotic patients and cases with both-bone involvement. Complications with K-wire fixation were more frequent in these subgroups. Conclusion Plate fixation may provide superior stability and functional outcomes in treating DRFs, particularly in complex cases involving osteoporosis or bone injuries. Further research with larger sample sizes and prospective design is recommended.

Percutaneous Titanium Elastic Nail Stabilization for Pelvic and Acetabular Fractures: Surgical Technique and Case Series.

The stabilization of fractures of the anterior pelvic ring and anterior column of the acetabulum with antegrade or retrograde intramedullary screws has been frequently described. However, these narrow and nonlinear bony corridors can be challenging and dangerous to accommodate with rigid linear implants. Titanium elastic nails (TEN) are ideal implants to navigate in the narrow, irregular medullary canal in this anatomical location. This study aims to describe this surgical technique and its preliminary results. From April 2018 to October 2023, patients who underwent acute TEN stabilization of their pelvic or acetabular fractures were identified from a review of medical records at a Level 1 trauma center. A focused review of their clinical documentation was performed to describe their demographics, injury patterns, the surgical techniques used in their treatment, and their clinical and radiographic outcomes. During the almost 6-year period, 19 patients were identified (age: 39 ± 22 years; 74% male). There were 3 acetabulum and 16 pelvic ring fractures stabilized. One of the 19 patients underwent bilateral TEN fixation of the superior pubic rami. Patients were followed-up through hospital outpatient clinics postoperatively (median follow-up 14 months, IQR: 8-24 months). No fractures were complicated by nonunion or secondary displacement of the reduction. A 14-year-old patient required hardware removal due to irritation, and a 19-month-old patient underwent planned hardware removal due to her age. No patients have undergone hip arthroplasty to date, and there were no instances of infection or neurovascular injury. These preliminary results are promising and suggest that larger scale assessment of the indications and feasibility of TEN stabilization in pelvic and acetabular surgery is warranted.

Pelvic Binder Radiography Is Safe and Feasible for Quantifying Fracture Instability in LC1 Pelvis Fractures: A Clinical Trial.

To demonstrate fracture displacement, patient tolerance, and in-hospital safety quantifying lateral compression type 1 (LC1) pelvis fracture stability with awake stress radiography using a pelvic binder (PBR). Prospective clinical trial of PBR diagnostic intervention. Two centers, Level I trauma center and academic hospital. Alert adults with LC1 (OTA/AO B1.1/2.1) pelvic fractures from blunt mechanism presenting within 3 weeks of injury between February and December 2023 without hypotension or injury precluding pelvic binder application. The primary outcome was fracture displacement on PBR. Secondary outcomes included feasibility (≥85% patient tolerance) and safety (no major adverse events). Exploratory outcomes included pain during examination, opioid medication consumption within 96 hours, length of hospital stay, discharge destination, and correlation between fracture displacement on PBR and examination under anesthetic. One hundred sixty-nine patients with pelvis fractures were screened, 58 were eligible, and 31 were enrolled. The mean age of enrolled patients was 58.7 ± 23 years, 54.8% were female, 22.6% were White, and 67.7% Hispanic. Fracture displacement was 4.3 ± 4.7 mm on PBR at 5 kg and 8.4 ± 9.0 mm at 10 kg. All patients tolerated PBR. Sixteen patients (52%) reported pain during PBR but completed the test. No patient experienced an adverse event. Patients received 40.4 ± 56.4 mg oral morphine equivalents within 96 hours of PBR. Ten patients (32.2%) received internal fixation. The median hospital stay was 6 days (interquartile range 5.5 days) with no inpatient mortality. Fourteen patients (45.2%) discharged home. PBR is feasible and safe as a point-of-care test for LC1 pelvis fracture instability. Level II Diagnostic.

Open Reduction and Internal Fixation of Mandibular Condyle Fractures Using AUTOFIX 2.0® Cannulated Compression Screw System: A Technical Innovation with Intraoperative CT-Scan

Condylar process fractures remain a matter of ongoing controversy in maxillofacial surgery because of variety of opinions and proposed treatment modalities offered in the literature. The trend is toward open reduction and internal fixation (ORIF) whenever there is displacement or dislocation combined with unstable occlusal conditions. The fundamental treatment goals are anatomical fixation and early return to function. However, ORIF of a fractured condyle carries significant risks, including facial nerve damage, and presents challenges in reducing and stabilizing the fractured segment in an area of limited access. We present here an innovative technique for ORIF of condylar head fractures. It consists in fracture reduction and stabilization with two Kirschner wires followed by osteosynthesis with two cannulated headless compression screws using the AUTOFIX 2.0® system (Stryker, Kalamazoo, USA). This new technique, combined with intraoperative CT scan, ensures satisfactory reduction and stabilization of the dislocated joint segment, thereby restoring the condyle to its physiologically normal position.

Outcomes of Intramedullary Nailing Versus Plate Fixation in the Management of Humeral Shaft Fractures: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis aimed to compare the outcomes of intramedullary nailing (IMN) and open reduction with internal fixation (ORIF) in treating traumatic humeral shaft fractures in adults (18 years and above). A comprehensive literature search was conducted in databases including PubMed, Google Scholar, Embase, and CochraneCentral Register of Controlled Trials (CENTRAL). The primary outcome was time to union, while secondary outcomes included non-union rates, incidences of iatrogenic radial nerve palsy, surgical site infections, and intra-operative comminution. Twenty-six studies, encompassing 1,674 patients (867 IMN, 807 ORIF), were included. IMN demonstrated a shorter time to union compared to ORIF (mean difference -1.06 (95% CI, -1.88 to -0.23)), with significant statistical heterogeneity (I² = 70%), and a mean difference of -2.14 (95% CI, -3.16 to -1.12) in the randomized controlled trial (RCT) subgroup analysis, which had no significant statistical heterogeneity. Both techniques had comparable non-union rates (risk ratio 0.34 (95% CI, 0.94 to 1.93)). IMN was associated with lower incidences of iatrogenic radial nerve palsy (risk ratio 0.48 (95% CI, 0.27 to 0.87)) and surgical site infections (risk ratio 0.44 (95% CI, 0.25 to 0.76)), but had a higher risk of intra-operative comminution (risk ratio 3.04 (95% CI, 1.24 to 7.44)). The studies exhibited significant heterogeneity and varying outcome measures, highlighting the need for cautious interpretation. IMN offers rapid fracture stabilization and minimal additional physiological insult, while ORIF remains preferable for achieving precise anatomical reduction. These findings highlight the importance of considering patient-specific factors and surgical expertise in selecting the appropriate fixation technique.

Functional outcome of treatment of fracture intertrochanteric femur by using proximal femoral nail antirotation II

Background: The elderly are most frequently affected by intertrochanteric fractures, which have a major effect on the medical community and society at large. In 2003, AO introduced the proximal femoral nail anti-rotation device, which was further improved and named proximal femoral nail antirotation II (PFNA II) in 2009. Methods: This study was conducted from December 2020 to August 2022. The 60 cases of proximal femoral nail anti-rotation II-managed intertrochanteric femur fractures were assessed. Results: In the present study, 24 patients (40%) had type IV (Evan’s) fractures. Right hip was involved in 30 patients (50%). Meantime for clinic-radiological union was 20 weeks. There was complication rate of 2.08% as helical blade protrusion and non-union, 2.08% as helical blade protrusion, 2.08% as blade backout, 4.17% as superficial infection and 4.17% as lateral wall fracture. Seven patients expired postoperatively within 3 months while 5 patients lost during follow Up. After a 6-month follow-up, the Harris hip grade was used to evaluate 48 instances. Of these, 8 cases (16.67%) had an excellent score, 29 cases (60.42%) had a good score, 7 cases (14.58%) had a fair score, and 4 cases (8.33%) had a poor score. Thirty-seven of the 48 cases had reached the one-year follow-up mark. Thus, of the 37 patients assessed, 11 cases (29.73%) had excellent Harris hip grades, 19 cases (51.35%) had good scores, 4 cases (10.81%) had fair scores, and 3 cases (8.11%) had poor scores at the end of a one-year follow-up. Conclusions: Even in rural populations, PFN A-II is a better, safer implant with a low rate of complications for treating stable and unstable intertrochanteric femur fractures.

National Trend of Surgical Stabilization of Rib Fractures: Indications, Approaches, and Disparities

IntroductionRib fractures are among the most frequent injuries in trauma. This study aims to assess the current nationwide trends in operative rib fixation and identify predictors of surgical stabilization of rib fractures (SSRFs). MethodsA 5-y (2017-2021) retrospective analysis of the Trauma Quality Improvement Program database was performed. Adult trauma patients who had at least one rib fracture were included. We analyzed data regarding type of SSRF including open and thoracoscopic approaches and its trends. ResultsA total of 780,275 patients were identified, of which 15,339 patients (1.9%) were managed with SSRF. Trends of both open and endoscopic approaches were increasing during the study period. Patients with ≤2 rib fractures had a decreasing rate of SSRF. Flail chest (odds ratio = 13.42, P < 0.001) was the strongest predictor of SSRF. ConclusionsSSRF is gaining popularity in the management of chest trauma. The presence of a flail segment and multiplicity of rib fractures is among the predictors of SSRF.

An early analysis of polyetheretherketone (PEEK) plates for the surgical stabilization of rib fractures: A pilot study

BackgroundSurgical stabilization of rib fractures (SSRF) is a viable treatment option for rib fracture patients. Polyetheretherketone (PEEK) plates have become available for SSRF. The objective of this pilot study was to examine the use of PEEK plates for SSRF. MethodsA prospective, observational, multi-center study of patients undergoing SSRF with PEEK plates from 4/23 through 2/24. Standard indications for SSRF were followed and the decision to use PEEK plates was left to the discretion of the treating surgeon. Basic demographics were obtained. Outcomes included the number of rib fractures stabilized with PEEK plates, complications related to SSRF, and 6-month follow-up with chest computed tomography (CT) to assess healing of PEEK repaired fracture sites, identified as complete or incomplete union. Patients also answered a five-question quality-of-life survey regarding mobility, self-care, usual activities, chest pain/discomfort, and anxiety/depression. Answers were scaled 1 to 5 (1=worse condition possible; 5=best possible condition). Patients rated their health on a scale of 0 to 100 (100=closet to their health preinjury). All data was reported as descriptive. ResultsForty-six patients were included. Average age was 57(±16) years; 82.6 % were male. Median ISS was 18 (IQR 14,29) and median chest-AIS was 4 (IQR 3,4). 219 rib fractures were stabilized with PEEK plates. Sixteen (34.8 %) had a combination (PEEK + titanium) procedure. Three patients had a complication: one required a second surgery for additional SSRF, and two patients were readmitted. Twenty-seven patients were surveyed at 6 months, and 19 agreed to CT scan. Eighty PEEK repaired rib fractures were assessed for healing. 80 % of fractures had complete union and no hardware failure. Quality-of-life survey averaged >4.5/category and mean overall health was 89. ConclusionPEEK plates for SSRF are safe and effective, allowing for adequate rib fracture healing and are associated with positive patient reported outcomes.

Internal Fixation With Cannulated Screws for Stable Femoral Neck Fractures in High-Risk Patients: Good Clinical Outcomes and Evaluation of Postoperative Complications

Differentiated approach to the treatment of femoral fractures in children 0–7 years old using osteosynthesis with flexible titanium rods

Background. Fractures of the femur, especially its diaphysis, are quite common in pediatric practice. One of the priorities in the treatment of hip fractures in children is elastic stable intramedullary osteosynthesis with flexible titanium rods (ESIN/TEN), however, the frequency of using conservative methods also remains high. Aim. To differentiate the approach to the treatment of femoral fractures in children aged 0–7 years. Materials and methods. The immediate results of treatment of femoral fractures in 118 children aged 0 to 7 years (mean age 3.3±1.8 years) were studied. The main group consisted of 62 children who underwent surgical treatment of diaphyseal femoral fractures, while ESIN osteosynthesis was performed in 56 patients. The reference group was formed by a retrospective analysis of the medical records of 56 children who received conservative treatment of hip fractures. Results. Compared with conservative methods, with ESIN, the overall rate of early complications (skin reaction) was significantly lower, there were no complications from the internal organs (kidneys, lungs), and there were 3 (4.8%) cases of fixative migration. The severity of pain after 3 weeks from the start of treatment in the main group decreased to 2.4±0.1 points (mild pain), and in the reference group – to 4.5±0.3 points (moderate pain; p=0.013). The average length of stay of patients in the hospital in the main group was 7.3±2.4 days, in the reference group – 21.2±5.9 days (p=0.008). Conclusion. ESIN is the optimal method of stabilization for diaphyseal fractures of the femur in children aged 0 to 7 years. The advantages of ESIN over conservative methods are lower morbidity, greater pain relief, and shorter hospital stays for children.

Non-surgical treatment of lateral malleolar fractures is safe: long-term follow-up of a comprehensive treatment algorithm

IntroductionA study at Sahlgrenska University Hospital (SU) found significant variation in the treatment of ankle fractures, leading to the development of a structured treatment algorithm (TA). The TA aimed to standardise treatment and reduce the number of unnecessary surgical procedures. A follow-up study concluded that the number of surgeries had significantly decreased since the TA was introduced. However, the long-term effects of the TA and the reduced number of surgical procedures remain unclear. The aim of the study was to analyse the long-term effects of a structured TA for ankle fractures, focusing on complications and reoperation rates.MethodThe present study is a long-term follow-up of the same two cohorts of patients with lateral malleolar fractures of type AO/OTA44-B1, as studied in the previous studies on the TA for ankle fractures at SU. The current study compares a group of AO/OTA 44B1 fractures treated before introducing the TA, the pre-TA cohort (n = 410), with a group treated after introducing the TA, the post-TA cohort (n = 333). Both cohorts were followed for at least four years, and the outcomes were reoperation or complication. Reoperation was defined as any surgical procedure performed ≥ 30 days after the injury.ResultsThe results highlight a statistically significant reduction in the reoperation rate for lateral malleolar ankle fractures from 7.1 to 2.4% (p = 0.006) after introducing a TA that reduced the number of primary surgical procedures. Hardware-related issues were identified as the dominant cause of reoperation in both cohorts. Three major reoperations were observed in the pre-TA cohort compared to none in the post-TA cohort. The present study revealed no increase in the frequency of reoperations (late surgeries) due to non-union.ConclusionThe non-surgical treatment of stable ankle fractures does not lead to an increase in reoperations caused by non-union. A TA that reduces the need for primary surgical procedures for lateral malleolar fractures of type AO/OTA44-B1 has resulted in a significant decrease in reoperation rates and no increase in failure rates. This long-term follow-up demonstrates that a non-surgical approach to isolated lateral malleolar fractures is safe.

Surgical management of costal margin rupture associated with intercostal hernia: Evolution of techniques

INTRODUCTION Costal margin rupture (CMR) injuries in association with intercostal hernia (IH) are rare and symptomatic and provide a significant surgical challenge. Surgical failure rates up to 60% are reported, and optimal techniques are unclear. We have characterized these injuries and describe the evolution of our surgical management techniques. METHODS Patients characterized by the Sheffield Classification where CMR and IH were both present, either CMR-IH or transdiaphragmatic intercostal hernia (TDIH), were identified prospectively, and injury characteristics, patient management, and follow-up data were recorded. Surgical techniques evolved according to patient outcomes from suture repair without and then with extrathoracic mesh, to three iterations of double-layer mesh repair (DLMR). The third iteration involved DLMR with biologic mesh, titanium buttress plates applied to the ribs adjacent to the IH with intercostal nerve-sparing suture placement. Associated surgical stabilization of rib fractures, or surgical stabilization of nonunited rib fractures, was performed when required, with costal margin plate fixation where possible. RESULTS Of 25 patients with CMR-IH and 11 with TDIH, 25 patients underwent surgery, with 6 reoperations in 5 patients. There were 8 suture repairs and 3 extrathoracic mesh repairs: DLMR was performed in 14 patients (3 Mark [Mk] 1, 5 Mk 2, and 6 Mk 3) with 2, 1, and 0 reoperations, respectively. Costal margin stabilization with titanium plates was successful twice at the level of the seventh but failed twice out of three times at the ninth costal cartilage. Reoperation after a failed mesh repair is particularly challenging and may require the placement of titanium buttress plates, surgical stabilization of rib fractures, and the use of stainless steel wire sutures. CONCLUSION Repair of CMR-IH/TDIH is challenging, but experience-based evolution of techniques has led to a durable and reproducible Mk 3 repair. LEVEL OF EVIDENCE Observational; Level III.

It doesn't hurt as long as I don't move: Aligning pain assessment in patients with rib fractures with mobilization needed for recovery.

Rib fracture pain is a major issue but likely underappreciated, given that patients avoid activity due to the pain. Pain is one criterion used to determine if someone is a candidate for surgical stabilization of rib fractures (SSRF). The purpose of this study was to assess pain for rib fracture patients, hypothesizing pain from rib fractures is underappreciated in current practice. A prospective study analyzing patients with one or more rib fractures admitted to our Level I trauma center from March 2023 through February 2024. Exclusion criteria included refusal to participate, ventilator dependent, younger than 18 years, moderate/severe traumatic brain injury, spinal cord injury, pregnancy, or incarceration. Basic demographics were obtained. Participants rated their pain on an 11-point Numerical Rating Scale while resting in bed and performing a series of movements (0, no pain; 10, worst pain imaginable). Movements included incentive spirometer, flexion, extension, bilateral side bending, bilateral rotation, and holding a 5-pound dumbbell. Patients undergoing SSRF were surveyed pre- and postoperatively. Outcomes included the difference between pain scores at rest versus performing all movements, difference between pain scores pre- and post-SSRF, and incentive spirometry pre- and postoperatively. Nonparametric analysis was completed with the Wilcoxon signed-rank test with statistical significance set at p < 0.05. One-hundred two patients were enrolled. The mean age was 60 ± 15 years; 57.8% were male. The median pain score at rest was 3 (interquartile range [IQR], 2-5.5). Pain scores significantly increased to >5 for all movements. Thirty-one patients underwent SSRF. Resting pain prior to SSRF was 3 (IQR, 1-6) and postoperatively was 2 (IQR, 1.5-3) (p = 0.446). For all movements, median Numerical Rating Scale score was significantly less after SSRF (p < 0.001). The median incentive spirometry was 1,100 mL (IQR, 625-1,600 mL) preoperatively and 2,000 mL (IQR, 1,475-2,250 mL) postoperatively. Traditional assessment of pain in patients with rib fractures significantly underappreciates true pain severity caused by movements involving the chest wall and should be considered when evaluating for SSRF.

Comparison of patients who meet criteria for surgical stabilization of rib fractures versus those who actually get rib fixation: A single center review

BackgroundSurgical stabilization of rib fractures (SSRF) has shown benefits for rib fracture patients. However, the incidence of SSRF performed remains low. We compare our institution's rib fracture patients meeting criteria for SSRF versus those actually receiving the operation, hypothesizing a significant portion are not undergoing SSRF. MethodsA retrospective review of rib fracture patients presenting to our Level 1 trauma center from 1/2016 to 4/2023. Patients were categorized as those who met SSRF inclusion criteria versus those who didn't based on the 2023 Chest Wall Injury Society (CWIS) SSRF Guidelines. Basic demographics were obtained. Patients meeting SSRF criteria were divided into those who received SSRF versus those who didn't. Outcomes of interest included type and frequency of SSRF indications and frequency of absolute/relative contraindications. Descriptive statistics were used. Median test and t-test were used for statistical analysis. Statistical significance was set at p < 0.05. ResultsA total of 3,432 patients presented with ≥1 rib fracture(s). Of those, 1,573(45.8 %) met SSRF inclusion criteria. These patients were predominantly male, with mean age of 57.4(±18.5) and a similar Injury Severity Score but significantly higher chest-Abbreviated Injury Score of 3 (Interquartile range 3,4)(p = 0.048). Only 458(29.1 %) patients underwent SSRF, leaving 1,115(70.9 %) managed non-operatively, of which 215(19.3 %) were ventilated and “failure to wean from the ventilator” was the most common (81.4 %) indication for SSRF. Of the 900(80.7 %) non-ventilated patients managed non-operatively, 659 (69.9 %) had ≥two indications for SSRF, 382(34.3 %) had zero relative contraindications and 394(35.3 %) had one relative contraindication for SSRF. Lastly, 52.6 % of patients in this cohort had reported “clicking/popping” of their fractures. ConclusionOnly 29.1 % of patients meeting criteria for SSRF had the operation based on data from our institution. There may be additional opportunity to benefit this cohort of patients meeting SSRF criteria but not undergoing surgery.

Dedicated Chest Wall Injury Program quality review: How to create and incorporate a quality and safety program for surgical stabilization of rib fractures.

Adoption of surgical stabilization of rib fractures (SSRF) in chest trauma necessitates outcomes reviews and process improvement (PI). As volume and complexity increase, such vigilance is imperative. Over 10 years, our center has developed a dedicated PI program based on our trauma PI program. Here, we outline the components of this program, aiming to share best practices and potentially improve SSRF patient outcomes. Over 10 years, our dedicated SSRF PI process has evolved to include bimonthly reviews on case and quality metrics. In 2022, all patients at our single high-volume Level 1 trauma center with flail chest segments were identified, and a PI chart review was conducted. Data collected included management approach (operative vs. nonoperative), postoperative complications, mortality, patient demographics, trauma specific variables (Injury Severity Score, etc.), and rib fracture details. Operative data collected included number of ribs plated, system used, and complication rates for each surgeon and plating system used. Of 82 patients identified, 88% underwent SSRF. Among these, 49% experienced one or more postoperative complications, not all directly related to SSRF procedures. Mortality rate for SSRF patients was 15%, predominantly in those with Injury Severity Score of >25 and mean age of 58 years. Patients who had trauma activations and required emergency department chest tube placement had higher complications. The mean number of ribs stabilized was four. Complications occurred more frequently with posterior fractures. Outcomes were collated and analyzed at SSRF Outcomes Committee. The utilization of SSRF underscores the need for a rigorous quality review process to enhance patient safety and SSRF-specific outcomes. Our program developed over time from and was implemented in fashion similar to the trauma PI processes. The resulting quality initiative has fostered center-specific PI projects and programmatic advancements. Economic and Value-Base Evaluations; Level IV.

A Biomechanical Analysis of Oblique Metacarpal Metadiaphyseal Fracture Fixation in a Cadaver Model

Although metacarpal fractures are typically managed nonoperatively, when surgical management is indicated, metacarpal fractures are commonly treated with crossed Kirschner wires (K-wires), which may limit early range of motion. Intramedullary implants are increasing in use with the potential advantage of early range of motion; however, stability in oblique metacarpal neck fractures remains a theoretical concern. The purpose of this study was to determine the biomechanical stability of noncompressive intramedullary fixation for oblique metacarpal neck fractures compared with crossed K-wire fixation. The index, long, and small metacarpals were harvested from three matched pairs of fresh-frozen cadavers. Oblique fractures at the metadiaphyseal region were created in each metacarpal. Each metacarpal was randomized to noncompressive, threaded intramedullary nail fixation or fixation with two crossed K-wires. Specimens were mounted in a Materials Testing System load frame and axially loaded until failure. Load to failure (LTF), stiffness, and load to 2 mm displacement were calculated from load-displacement curves. Differences in peak LTF, stiffness, and load to 2 mm displacement between noncompressive intramedullary fixation and crossed K-wire fixation were evaluated. The noncompressive intramedullary fixation cohort had a significantly higher LTF (1,190.9 ± 534.7 N vs 297.0 ± 156.0 N) and stiffness (551.3 ± 164.6 N/mm vs 283.0 ± 194.5 N/mm) when compared with the crossed K-wire fixation cohort. Load at 2 mm displacement was greater in the noncompressive intramedullary fixation cohort compared with crossed K-wire fixation (820.5 ± 203.9 vs 514.1 ± 259.6). For oblique metadiaphyseal metacarpal fractures, noncompressive intramedullary fixation provides a biomechanically superior construct under axial loading in terms of LTF, stiffness, and load to 2 mm of displacement compared with crossed K-wire fixation. Noncompressive intramedullary nails may be an alternative to K-wire fixation for the treatment of oblique metadiaphyseal metacarpal fractures.
