Ligament Sparing Elbow Hemiarthroplasty: A Novel Technique for the Management of Distal Humeral Fractures.

Intra-articular distal humerus fractures present various challenges with a wide array of treatment options. Open reduction internal fixation remains the treatment of choice. In older patient populations with poor bone quality and short-end segment fractures with articular comminution, open reduction internal fixation, however, may bring on unsurmountable technical challenges. Total elbow arthroplasty and elbow hemiarthroplasty (EHA) may offer superior functional outcomes in these cases. During EHA for fractures, the medial and lateral columns are reconstructed with the collateral ligaments to restore elbow stability. We hypothesize that in coronal sheer fracture patterns where the columns are intact, maintaining the native collateral ligaments and columns will provide both an anatomic and stable elbow joint. We introduce the ligament sparing EHA technique for unreconstructible coronal shear fractures. We describe this novel technique and compare our postoperative outcomes in 2 patients who underwent this surgery to those described in the literature. The postoperative Disabilities of the Arm, Shoulder, and Hand scores for the 2 patients were 13.8 and 10.3, respectively. The Mayo Elbow Performance Score for the 2 patients were 80 and 85, respectively. The operative arm presented a grip strength of 82% and 89% when compared with the contralateral arm, for the patients respectively. The range of motion varied between 78% and 100% of the contralateral arm for both patients. Although our results are promising and the ligament sparing EHA technique may be a more anatomic option in certain fracture patterns, further research with larger cohorts and multiple surgeons is needed to reinforce our results.

Clinical Outcomes of Arthroscopic Adhesiolysis: A Case Series of 40 Patients With Postoperative Knee Stiffness.

Introduction Restricted range of motion over the knee joint is a known complication following the surgical procedure. Aggressive rehabilitation protocols can initially manage knee stiffness due to arthrofibrosis. If conservative management fails, surgical (open or arthroscopic) release is the preferred modality of management. We present a series of 40 patients with postoperativeknee stiffness who were treated with arthroscopic adhesiolysis. Material and methods This is a retrospective study conducted at Phoenix Orthopedic Superspeciality Hospital, Nagpur, India, from 2017 to 2021. Our study included 40 patients with postoperative knee joint stiffness, of whom 27 were males and 13 were females. The study considered the duration of stiffness, which ranged from six months to five years. All patients underwent arthroscopic knee release. A rigorously supervised physical therapy program followed this procedure. Patients were examined at three months, six months, and one year to assess improvement in knee range of movement. Results Out of 40 patients, six were classified as Shelbourne type 4, and the remaining were Shelbourne type 3. Twenty-three of 40 patients developed arthrofibrosis following intra-articular or peri-articular fracture fixation surgery; 11 patients were operated on arthroscopically for anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) reconstruction. Three patients developed stiffness following total knee replacement, one following patellectomy, and three following infection after fracture fixation. The mean pre-op knee range of motion (ROM) was 48.875 degrees. Following arthroscopic release, the mean improvement in ROM was 60 degrees intra-operatively. The average postoperative range was 108.25 degrees. Conclusion Arthroscopic adhesiolysis and quadriceps release are reliable methods for dealing with postoperative knee stiffness. It prevents wound complications and increases the chances of surgical site infection due to smaller incisions. Postoperatively, we achieved an average increase of 60 degrees in ROM over the knee joint.

Clinical Outcomes and Management Strategies for Capitellum and Trochlea Fractures: A Systematic Review.

Capitellum and trochlea fractures, also referred to as coronal shear fractures of the distal humerus, are infrequent yet challenging intra-articular fractures of the elbow. There are a variety of surgical approaches and fixation methods with often variable outcomes. This systematic review investigates interventions, outcomes and complications of capitellum and trochlea fractures. A systematic review of studies published in MEDLINE, EMBASE, Web of Science and Cumulative Index to Nursing and Allied Health literature (CINAHL) was conducted to assess the clinical outcomes of capitellum and trochlea fractures managed surgically. Data on patient demographics, surgical approach, implant usage, postoperative outcomes and complications were compiled. Forty-one studies met the inclusion criteria with a total of 700 patients. Surgical interventions primarily utilized either the lateral (79%) or antero-lateral (15%) approaches with headless compression screws as the most common fixation method (68%). Clinical outcomes were measured using the Mayo Elbow Performance Index (MEPI) with a mean score of 89.9 (±2.6) and the DASH score with a mean of 16.9 (±7.3). Elbow range of motion showed a mean flexion of 126.3° (±19.4), extension of 5.71° (±11.8), pronation of 75.23° (±12.2), and supination of 76.6° (±9.8). The mean flexion-extension arc was 113.7° (±16.9), and the mean pronation-supination arc was 165.31° (±9.41). Complications occurred in 19.8% of cases, with re-interventions required in 8.3% of cases, mainly due to symptomatic implants and elbow stiffness requiring surgical release. Other complications included implant removal (10.4%), overall reported stiff elbows (6%), nerve palsies (2%), non-union (1.5%), and infection (1.2%). The treatment of capitellum and trochlea fractures yields satisfactory outcomes but has a considerable rate of complications and reoperations primarily due to symptomatic implants and elbow stiffness. There is noteworthy variability in the achieved range of motion, suggesting unpredictable outcomes. Deficits in functionality and range of motion are common after surgery, especially with more complex injury patterns.

Potential Roles of Inflammation on Post-Traumatic Osteoarthritis of the Ankle.

Post-traumatic osteoarthritis of the ankle (PTOA) is frequently observed following a debilitating consequence of intra-articular ankle fractures. Numerous risk factors contribute to the pathogenesis of PTOA, including articular incongruity, joint malalignment, and concomitant soft tissue damage. Despite attempts to restore joint anatomy and manage soft tissues to avoid long-term complications after intra-articular ankle fractures, the incidence of PTOA remains markedly elevated. Inflammatory processes triggered by intra-articular ankle fractures have emerged as potential instigators that expedite the progression of PTOA. Injury to the articular cartilage and subchondral bone may lead to the release of inflammatory mediators, which can contribute to cartilage degradation and bone resorption. This study provides a narrative review on the current knowledge concerning the association between inflammation and the development of PTOA following intra-articular ankle fractures. We also discuss novel therapeutic agents that target inflammatory pathways to impede the progression of post-traumatic osteoarthritis after intra-articular ankle fractures. These medication and interventions were summarized within this review article.

A newly designed anatomical plate for the therapy of posterolateral tibial plateau fracture via a supra-fibular-head approach: a retrospective study.

The posterolateral tibial plateau fracture is a special type of intra-articular fracture, for which there is no simple, safe, and effective standardized procedure. In this paper, we evaluate the clinical efficacy and the advantages of the treatment of posterolateral tibial plateau fracture by using our designed proximal lateral tibial rim plate for the posterolateral condyle of the tibial plateau via the space above the fibula head. Thirty-eight patients with posterolateral tibial plateau fractures from June 2018 to June 2021 were retrospectively analyzed. CT scans were used to classify the degree of injury in the included patients. All of them were fixed with reduction using an approach above the fibula head combined with a homemade anatomical plate. The regular postoperative review was performed to instruct functional knee exercises. Postoperative complications were observed and follow-up visits were performed to assess the functional outcome. A total of 38 patients with posterolateral tibial plateau fractures, 13 males and 25 females were included in the study. All patients were followed up for 13-26months, with a mean of 15.3months. There were no postoperative complications such as numbness of the limb, knee joint instability, etc. X-ray review showed that the fractures were all healed, and the healing time was 10-16weeks, with an average of 12.1weeks; none of the internal fixation loosening and loss of articular surface occurred during the follow-up period. At the last follow-up, according to the HSS knee function score criteria, the scores were 79-98, with an average of 91.3. The HSS score presented excellent in 34 cases (89%) and good in 4 cases (11%). The Rasmussen score was graded as excellent in 29 cases (76%) and good in 9 cases (24%). In conclusion, The treatment of posterolateral tibial plateau fractures by an approach above the fibula head has the advantages of simplicity and safety, small trauma, and no risk of vascular and nerve injuries, and the anatomical proximal lateral tibial rim plate can play a direct and effective supporting role for the bone fragments of the posterolateral condyle, and the combination of both of them has obvious advantages in the treatment of posterolateral condylar fracture of the tibial plateau, and it is a method worth borrowing and popularizing.

EVALUATING SHORT-TERM OUTCOMES POST- INTRA-ARTICULAR CALCANEAL FRACTURE FIXATION VIA A SINUS TARSI APPROACH IN A NON-EXCLUSIVELY SELECTED COHORT

AimsManagement of intra-articular calcaneal fractures remains a debated topic in orthopaedics, with operative fixation often held in reserve due to concerns regarding perioperative morbidity and potential complications. The purpose of this study was to identify the characteristics of patients who developed surgical complications to inform the future stratification of patients best suited to operative treatment for intra-articular calcaneal fractures and those in whom surgery was highly likely to produce an equivocal functional outcome with potential post-operative complications.MethodsAll patients who underwent open reduction and internal fixation of calcaneal fractures utilizing the Sinus Tarsi approach between March 2014 and July 2018 were identified using theatre records. Patient imaging was used to assess pre- and post-operative fracture geometry with Computed Tomography (CT) used for pre-operative planning. Each patient's clinical presentation was established through retrospective analysis of medical records. Patients provided verbal consent to participation and patient reported outcome measures were recorded using the Maryland Foot Score.ResultsFifty-eight intra-articular calcaneal fractures (fifty-three patients including five bilateral, mean age = 46.91 years) were included. Forty-nine patients were injured as a result of a fall from a height (92.4%). Mean time from presentation to surgery was 3.23 days (range 0–21). Mean Maryland Foot score was found to be 77.6 (+/− 16.22) in forty-five patients. Five patients (9.4%) had wound complications; two superficial (3.7%) and three deep (5.6%).ConclusionIntra-articular fractures of the calcaneus should be considered for surgical intervention in order to improve long-term functional outcomes. The Sinus Tarsi approach provides the potential to decrease the operative complication rate whilst maintaining adequate fixation, however, the decision to surgically manage these fractures should be carefully balanced against the risk of post-operative complications. This increased risk of complication associated with smoking may tip the balance against benefit from surgical management.

Our Experience with Primary Trapeziometacarpal Implant Arthroplasty in Severely Comminuted Rolando Fractures

Abstract Background The concept of primary joint replacement in severely comminuted fractures in elderly patients has proven to be a suitable treatment option in the shoulder, elbow and knee joint. Comminuted intra-articular fractures of the first metacarpal base can pose significant technical challenges, and no established gold standard treatment currently exists. Conventional methods like open reduction and internal fixation or external fixation are commonly employed, emphasizing the importance of anatomical reduction for restoring the articular surface. However, achieving articular surface congruity is often unattainable in severely comminuted intra-articular fractures, leading to short-term joint stiffness and instability, as well as long-term complications like secondary osteoarthritis. Aims This case report aims to share our experience with the use of primary trapeziometacarpal implant arthroplasty in the treatment of two patients with severely comminuted Rolando fractures. Methods In two cases of comminuted Rolando fractures, a primary trapeziometacarpal prosthesis (MAÏA™) was implanted based on preoperative decision-making facilitated by 3D-CT analysis. Patient’s visual analogue score for pain, range of motion, pinch and grip strength compared to the contralateral side were asked and examined. Results Both patients exhibited successful adaptation to their daily routines within a three-month postoperative period. No complications, such as cup or stem loosening or dislocation, were identified. Both patients almost reached equal range of motion, pinch and grip strength compared to the contralateral side. Conclusion The use of primary trapeziometacarpal implant arthroplasty seems to be a viable alternative for managing severely comminuted Rolando fractures, particularly in elderly patients and those with pre-existing osteoarthritis. This approach offers promising outcomes. Studies with other implant arthroplasties have shown better outcomes in patients treated primarily, than after several failed surgeries. We suggest the same is true for the trapeziometacarpal joint. Further studies are necessary to validate the efficacy of this intervention in a larger cohort of patients.

Management of complete intra-articular distal femur and patellar fractures in an achondroplastic young adult; small is challenging’ revisited: a case-report

BackgroundPeople with achondroplasia exhibit distinct physical characteristics, but their cognitive abilities remain within the normal range. The challenges encountered during surgical procedures and perioperative care for achondroplastic individuals, are underrepresented in the existing literature.Case presentationIn this report, the management of a 26-year-old North-African achondroplastic male is highlighted. The patient suffered a complete intra-articular distal femur fracture (AO/OTA 33-C1) and an ipsilateral patella fracture (AO/OTA 34-C1). The patient’s unusual anatomical variations and the lack of suitable orthopedic implants posed significant surgical challenges, particularly in the context of a resource-limited developing country. Facial and spinal deformities, which are common in patients with achondroplasia, further complicated the anesthetic approach.ConclusionsThe limited information on operative management of fractures in achondroplastic patients necessitated independent decision-making and diverging from the convenient approach where clear guidance is available in the literature.

Experience in the Use of Surgical Access to the Distal Part of the Radius in Comminuted Intra-articular Fractures

Introduction. Fractures of the distal radius occupy a leading place in the general structure of limb injuries. In most cases, they are comminuted in nature and require open reduction and fixation. With traditional surgical approaches to the distal radius, there is a risk of injury to the tendons of the muscles of the anterior group of the forearm and the median nerve; in addition, the skin incision lines pass through the projection of the gap of the wrist joint, which leads to the formation of painful scars and difficulty moving in the early postoperative period.The purpose of the work is to evaluate the results of using a new surgical approach to the distal radius for the treatment of comminuted intra-articular fractures.Materials and methods. A retrospective analysis of the results of surgical treatment of 124 patients aged 19 to 78 years with a fracture of the distal radius for the period from 2015 to 2019 was carried out. A patient with a fracture of the distal epimetaphysis of the radius, Fernandez type III, underwent surgery through the proposed approach.Results. Aſter transosseous osteosynthesis with a distraction external fixation device, on the sixth day, open reduction, bone graſting and plate osteosynthesis were performed through the proposed approach. Restoration of congruence of the articular surfaces of the wrist joint has been achieved. In the early postoperative period, movement in the joint is free, discomfort during the rehabilitation program is minimal. Aſter 12 months, movements in the joint are fully realized.Discussion. The new access makes it possible to improve the conditions for operations on the distal part of the radius with its fractures, creates a sufficiently spacious and safe access to the radius, which allows you to preserve the muscular part of the square pronator and does not violate the anatomy of the synovial sheaths of the tendons of the muscles of the anterior forearm group, which is prevention of the development of deficiency of rotational movements of the forearm and contractures of the hand and fingers in early and late postoperative periods.Conclusion. The developed new surgical approach to the distal radius provides optimalvisualization of the fracture andis low-traumatic, which has a positive effect on restoring full range of motionin the wrist jointin the early stages aſter surgery.

Pins and Rubbers Traction System for Treatment of Intraarticular Fractures of Distal Interphalangeal Joint.

Background: The pins and rubber traction system (PRTS) has proven effective in managing intra-articular fractures of the proximal interphalangeal joint. However, there is scant evidence in the literature regarding its efficacy in treating distal interphalangeal joint (DIPJ). This study aims to investigate the outcomes of PRTS in the treatment of comminuted intra-articular fractures of the DIPJ. Methods: We conducted a retrospective review of patients with comminuted intra-articular fractures of the DIPJ treated with PRTS between 2017 and 2021. At the final follow-up, we measured and compared the active range of motion (ROM) in both affected and non-injured contralateral fingers. The subjective evaluation utilised the Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH) questionnaire and the Visual Analogue Scale (VAS). Results: Ten patients with a mean follow-up of 13.2 months (range: 12-17) were included in the study. Fracture locations included the base of the distal phalanx in two patients, the condyle of the middle phalanx in seven and both in one patient. At the final follow-up, the average VAS score was 0.5 (range: 0-2). The average active motion of the DIPJ was 61° (range: 50°-70°) for the injured side and 76° (range: 75°-80°) for the opposite side. The mean range of DIPJ movement was 80% (range: 68%-87%) of the non-injured side. Extension deficits were observed in five patients, with a median deficit value of 10° (range: 5°-10°). The average Quick-DASH score was 2.9 (range: 0-11.3). Conclusions: The PRTS can be considered as an effective surgical technique in managing comminuted intra-articular fractures of the DIPJ. Level of Evidence: Level IV (Therapeutic).

VARIABLE ANGLE LOCKING PLATE VERSUS MULTIPLE K WIRE FIXATION FOR INTRA-ARTICULAR DISTAL RADIUS FRACTURE: A PROSPECTIVE COMPARATIVE STUDY OF FUNCTIONAL OUTCOME IN ELDERLY

Distal radius fracture (DRF) is a common wrist injury and it accounts for about one-sixth of emergency department visits. In spite of availability of various treatment options, none is universally effective for comminuted intraarticular fracture, because of varied fractures patterns. Two commonly used surgical methods are multiple K-wire fixation and open reduction and internal fixation by variable angle locking plates. Objective of the study was to compare functional outcomes of variable angle locking plate and multiple K wire fixation for intra-articular distal radius fracture in elderly. Prospective observational study was conducted among the patients of distal radius fractures with age more than 50 years. Patients were divided in to two groups with 24 cases in each group. Group one included patients treated with variable angle locking plate and group two included patients treated with multiple K-wires. Post surgery patients were assessed at 6 weeks, 3, 6 and 12 months. Evaluation was done clinically, and the outcomes were assessed by using the Disabilities Arm, Shoulder and Hand (quickDASH) score (primary outcome), Patient-Rated Wrist Evaluation (PRWE) score, range of motion, grip strength and were compared between the groups. Patients treated with variable angle locking plate was found to have better functional outcome than those treated with multiple K-wire initially during the study, but later by the end of the study at 12 months, both groups were found to be having similar outcomes, with no significant difference between the groups. This signifies that among variable angle locking plate and multiple K-wire fixation, no single procedure is superior to the other in long term.

Is it necessary to graft the void defect during open reduction and internal fixation of calcaneal fractures?

There are still controversies on the effect of grafting during open reduction and internal fixation of calcaneal fractures. The aim of this study was to compare the radiological and functional outcomes in patients with or without intraoperative grafting. In a comparative retrospective study, among 442 operatively-treated calcaneal fractures, 60 patients with unilateral closed sanders type II intraarticular calcaneal fracture who underwent ORIF via lateral extensile approach using locking anatomical plates with at least 1year follow-up without any postoperative wound complication were enrolled. The patients were separated into 2 groups: with bone allograft and without bone allograft. The functional outcome of the patients was assessed using visual analog scale (VAS) for pain, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, foot function index (FFI), and short-form (SF-36) health survey. Radiographic variables included Böhler angle, Gissane angle, calcaneal width, calcaneal height, and talar declination angle. Also, the differences (delta) of these values in comparison to the uninjured foot were calculated. The mean age was 39.1 ± 12.7 (range, 13-67) years with 54 males, 90.0%. No statistically significant differences were detected in age, gender, affected side, and subtypes of calcaneal fractures between the two groups (p > 0.05). The average follow-up was 25.1 (range, 12-48) months. The differences for all radiographic measurements and also, the delta values between the groups were not statistically significant, except talar declination angle which was more in cases without grafting (p = 0.007). Although the differences between the two groups regarding AOFAS ankle-hindfoot scale (p = 0.257), VAS for pain (p = 0.645), and FFI (p = 0.261) were not statistically significant; the group with bone graft experienced less pain (19.7 ± 22.0) than the other group (26.7 ± 22.8). The difference between the groups was not statistically significant (p = 0.87) according to the SF-36 questionnaire. Incorporating allografts into the void defects during ORIF of displaced intraarticular calcaneal fractures may not improve functional outcomes and recover postoperative radiological parameters. Therefore, routine use of allograft to fill the defects during ORIF of calcaneus may not be recommended. Of note, that these findings solely relate to the treatment of Sanders type II fractures. Comparative retrospective study.

What to Expect? Use of Supplemental Fixation With a Concomitant Dorsal Spanning Plate for Complex Intraarticular Distal Radius Fractures.

The dorsal spanning plate (DSP) is a versatile implant suitable for bridging severely comminuted intraarticular distal radius fractures [AO (Arbeitsgemeinschaft für Osteosynthesefragen) 23-C.1-C.3]. It may be used alone or with supplemental fixation such as a volar locking plate (VLP) or fragment-specific fixation (FSF). Outcomes following DSP fixation with additional implants have not been specifically evaluated. We retrospectively reviewed consecutive patients who underwent internal fixation of a distal radius fracture by a single surgeon from 2017 to 2021. Patients were grouped according to implants used: DSP only, DSP + FSF, and DSP + VLP. Preoperative variables, treatment times, and wrist range of motion (ROM) were assessed. Functional wrist ROM was defined as minimum 80° combined flexion and extension. One hundred fifty-two patients underwent surgery for wrist fracture, 33 of them were treated with a DSP: 8 DSP only, 6 DSP + VLP, and 19 DSP + FSF. Falls from height greater than 10 ft accounted for 52% of injuries, most of which were treated with a DSP + FSF. Treatment times and ROM were similar between subgroups. Wrist ROM did not improve significantly beyond 4 weeks following DSP removal. Overall, DSP patients recovered a mean wrist ROM of 85° (range 0°-130°) within a median 26 weeks total treatment period (range 12-68 weeks). Regardless of the construct used, if the distal radius articular surface is well reduced and other principles of fracture fixation are applied, most patients treated with a DSP can expect to regain functional wrist ROM. Level IV-Retrospective review of prospectively collected data.

Intra-articular Calcaneal Fractures: A Report of Cases and Comments on Preoperative Management.

To present a review of the clinical characteristics, preoperative and surgical management, and outcomes of patients with intra-articular calcaneal fractures who had open reduction and internal fixation (ORIF) and to offer some comments on and research ideas for the preoperative management of patients with these fractures. We studied consecutive patients who had ORIF performed by a single surgeon for closed, intra-articular calcaneal fractures at our level-1 trauma center between 5/29/2012 and 3/20/2018. All inpatients were treated with a preoperative soft tissue management protocol, whereas outpatients were not. Data were obtained about demographic and clinical characteristics, times from injury to surgery, quality of fracture reductions, and complication rates. Mean follow-up for the 72 patients with 77 calcaneal fractures was 8.5 (range: 1-43) months, and 21 (27.3%) fractures received inpatient preoperative care with a soft tissue management protocol, while 56 (72.7%) received outpatient preoperative management. More of the fractures treated preoperatively as inpatients versus outpatients were classified as Sanders type III (66.7% vs. 32.1%) and type IV (8.9% vs. 4.8%) fractures and were associated with polytrauma (38.1% vs. 7.1%) and diabetes mellitus (9.5% vs. 5.4%), respectively. For all patients, the mean time from injury to surgery was 12.2 (range: 2.7-19.4) days, and the time was 6.3 days for inpatients and 14.4 days for outpatients, but the quality of fracture reductions and complication rates did not differ between these two groups. Patients with intra-articular calcaneal fractures treated as inpatients and receiving a preoperative soft tissue management protocol had outcomes after ORIF that were not inferior to those experienced by patients treated preoperatively as outpatients, despite a greater proportion of the inpatients having severe fractures, polytrauma, and diabetes mellitus. Dedicated preoperative soft tissue management protocols may be beneficial for patients with calcaneal fractures and warrant further study.

Stable Clinical and Radiological Outcomes at Medium and over 5 Year Follow Up of Calcaneus Fracture Open Reduction Internal Fixation Using a Sinus Tarsi Approach

The sinus tarsi approach is increasingly growing in popularity for open reduction internal fixation of calcaneus fractures. Multiple studies have demonstrated favorable short-term results compared to the traditional extensile L incision, however long-term data over 5 years is currently limited to a single retrospective case series. Following local ethical approval, all patients who had completed a minimum 5 years from time of operation were contacted with a Standardized Telephone Questionnaire completed. This followed a previous retrospective chart review, with follow up telephone or clinic consultation performed by Davey et al. of this cohort at mean 35 months. Thirty-four fractures (31 patients) completed minimum 5 year follow up from the eligible group of 54 fractures (49 patients). Regarding functional outcomes, a significant improvement in mean Maryland Foot Score was observed between short- (mean 35.8 months) and medium-term (mean 81.9 months) of 77.6 (SD 15.0) to 86 (SD 7.9) (p = .0082). There was no significant difference in postoperative and long term radiographic Bohler's angle (p = .9683). Eleven feet (32%) proceeded to require reoperation, with removal of metal performed in 10 (29%), fusion in 2 (6%), and skin grafting following wound breakdown for 1 (3%). Four feet (12.9%) experienced post operative wound complications, including 3 (9.68%) cases of infection and 2 (6.45%) of delayed wound healing. This study demonstrated stable clinical and radiographic outcomes over 5 years following Calcaneus Fracture Open Reduction Internal Fixation using a sinus tarsi approach, supporting its continued usage when treating intraarticular calcaneus fractures for which operative intervention is indicated.

Sonographic diagnosis of radiographically undetectable bennet fracture.

Intra-articular fractures of the base of the first metacarpal (Bennet fractures) are prone to dislocation and require surgical reduction and fixation to prevent secondary degenerative joint disease and chronic dysfunction. Therefore, a prompt diagnosis is necessary, mostly achieved by conventional roentgenograms. We report the case of a 62-year-old man in whom a Bennet fracture was highly suspected on ultrasound (US) examination realized after a fall. Standard radiographs, obtained after US to confirm the diagnosis, were interpreted as normal. A computed tomography was then performed showing a typical Bennet fracture. This case report demonstrates that a careful assessment of bones must be an integral part of any routine musculo-skeletal US examination, particularly in post-traumatic patients. US can detect bone fractures where radiograph is not discriminating.

Comparison between intramedullary nail and conventional plate for displaced intra-articular calcaneal fractures: A meta-analysis.

This study aimed to compare the efficacy and safety of the intramedullary nail and conventional plate for the treatment of displaced intra-articular calcaneal fractures from clinical comparative trials. A comprehensive search of English databases was carried out in the Springer, PubMed, ScienceDirect, Web of Science, and Cochrane Library databases until September 2023. Studies on calcaneal fractures treated by an intramedullary nail or a plate were considered for inclusion. Endpoints included duration of operation, length of hospital stay, the Visual Analog Scale (VAS) score, postoperative functional score, radiological parameters, and complications. The mean difference (MD) and risk difference (RD) as the combined variables, as well as the 95% confidence intervals, (CIs) were calculated. Five retrospective controlled studies covering 473 feet at the one-year follow-up met the inclusion criteria. The meta-analysis demonstrated that there were significant differences in the duration of operation (MD: -10.81; 95% CI: -16.32, -5.31; p=0.0001), length of hospital stay (MD: -3.65; 95% CI: -4.35, -2.95; p<0.00001). No significant differences were found regarding postoperative American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale (MD: 0.36; 95% CI: -3.89, 4.61; p=0.87), VAS (MD: 1.95; 95% CI: -0.30, 4.21; p=0.09), or postoperative Böhler angle (MD: 0.94; 95% CI: -0.04, 1.92; p=0.06) between the two groups. The incidence of total complications (RD: -0.31; 95% CI: -0.46, -0.17; p<0.0001) and wound-healing complications (RD: -0.16; 95% CI: -0.30, -0.03; p=0.02) were lower in the intramedullary nail group. There were no significant differences in the incidences of revision surgery, implant removal, superficial wound infection, deep infection, and nonunion. Compared to conventional plates, the intramedullary nail showed a shorter duration of operation, reduced length of hospital stay, and fewer postoperative total complications and wound-healing complications in treating displaced intra-articular calcaneal fractures.

Hindfoot kinematics and kinetics - A combined in vivo and in silico analysis approach

BackgroundThe complex anatomical structure of the foot-ankle imposes challenges to accurately quantify detailed hindfoot kinematics and estimate musculoskeletal loading parameters. Most systems used to capture or estimate dynamic joint function oversimplify the anatomical structure by reducing its complexity. Research QuestionCan four dimensional computed tomography (4D CT) imaging in combination with an innovative foot manipulator capture in vivo hindfoot kinematics during a simulated stance phase of walking and can talocrural and subtalar articular joint mechanics be estimated based on a detailed in silico musculoskeletal foot-ankle model. MethodsA foot manipulator imposed plantar/dorsiflexion and inversion/eversion representing a healthy stance phase of gait in 12 healthy participants while simultaneously acquiring 4D CT images. Participant-specific 3D hindfoot rotations and translations were calculated based on bone-specific anatomical coordinate systems. Articular cartilage contact area and contact pressure of the talocrural and subtalar joints were estimated using an extended foot-ankle model updated with an elastic foundation contact model upon prescribing the participant-specific rotations measured in the 4D CT measurement. ResultsPlantar/dorsiflexion predominantly occurred at the talocrural joint (RoM 15.9±3.9°), while inversion/eversion (RoM 5.9±3.9°) occurred mostly at the subtalar joint, with the contact area being larger at the subtalar than at the talocrural joint. Contact pressure was evenly distributed between the talocrural and subtalar joint at the beginning of the simulated stance phase but was then redistributed from the talocrural to the subtalar joint with increasing dorsiflexion. SignificanceIn a clinical case study, the healthy participants were compared with four patients after surgically treaded intra-articular calcaneal fracture. The proposed workflow was able to detect small but meaningful differences in hindfoot kinematics and kinetics, indicative of remaining hindfoot pathomechanics that may influence the onset and progression of degenerative joint diseases.
