Biomechanical analysis of posteromedial tibial plateau fracture fixation in fresh cadaveric bone

This study aims to compare the mechanical strength of three different posterior-based internal fixation methods for posteromedial tibial plateau fractures. The study utilized 12 tibial plateaus harvested from fresh-frozen cadavers, and the posteromedial fracture fragments were created. The bones were then randomly assigned to one of three fixation methods: two posteroanterior lag screws (LS) size 4.0 mm, posterior buttress plate using a 3.5 mm small dynamic compression plate (DCP), or posterior buttress plate using a 3.5 mm T-shaped plate (TP). Biomechanical testing was performed by applying vertical compression force to the center of the posteromedial fracture fragment until the load to failure (displacement ≥ 3 mm) was reached, and displacement of the fragment was measured using a motion sensor. The data exhibited normal distribution, and one-way analysis of variance (ANOVA) was used to determine the load to failure, followed by Fisher post hoc Least-Significant Difference (LSD) to correct for multiple comparisons. The statistical analysis demonstrated significantly higher mean load to failure values in the T-shaped plate group compared to both the small dynamic compression plate group and the lag screw group (p < 0.05). However, after conducting further post hoc analysis, the observed significant differences were solely between the LS and TP groups (p = 0.021). These findings suggest that the T-shaped plate represents the most effective method for internally fixing posteromedial tibial plateau fractures.

An Observational Study on the Functional Outcomes of Intramedullary Nailing Versus Dynamic Compression Plating for Humeral Shaft Fractures

Objectives: The purpose of this research is to evaluate and contrast the functional results of Dynamic Compression Plating and Interlock Nailing for Humeral Shaft Fractures. Material and Methods: The design of this study was a prospective observational study. This study was conducted in DHQ Teaching Hospital Gujranwala and the duration of this study was from October 2020 to December 2022. We evaluated a total of 60 cases after receiving ethics committee permission from our institute. In DHQ Teaching Hospital Gujranwala, a study on instances of humeral shaft fractures needing surgical intervention was conducted. Results: In the plating group, 76.7% of the cases had outstanding results, compared to 56.7% in the nailing group. Moreover, the nailing group had a worse overall result (13.4% vs. 10%). Conclusion: Locking plating and intramedullary nailing had statistically similar results for individuals undergoing surgical intervention for humeral shaft fractures. In terms of union and function, both provide excellent and favourable results, but the dynamic compression plating group had a higher percentage of positive results and a propensity for union.

To Study Functional Outcome of Humeral Shaft Fractures Treated by Intramedullary Nailing Versus Dynamic Compression Plating at a Tertiary Health Care Centre

Background: The proportion of humeral shaft fractures being treated conservatively reportedly varies from 33% to 95%. Nonsurgical treatment results in higher incidence of union and fewer complications than open reduction and internal fixation. Aims and Objectives: To study and compare the functional outcome of Dynamic Compression Plating and Interlock Nailing for humeral shaft fractures. Material and Methods: After taking approval of ethics committee of our institute, we studied a total of sixty cases over a span of 36 months – October 2018 to December 2020. Study was carried out on cases of humeral shaft fractures requiring operational intervention in department of orthopaedics of tertiary care centre in Maharashtra. Results: A total of 76.7% cases in plating group had excellent outcome as compared to 56.7% in nailing group. Also poor to fair outcome was noted more in nailing group (13.4% vs 10%). Conclusion: Statistically comparable results have been observed for patients undergoing surgical intervention for humeral shaft fractures among locking plating and intramedullary nailing. Both provide excellent and favourable results in terms of union and function, however a higher rate of excellent results and tendency for union was seen with dynamic compression plating group.

Dynamic compression plating with interlocking nailing for fracture shaft of humerus in adult: A prospective study

Background: In orthopaedics, a humerus fracture is a frequent yet difficult to treat problem. Unless complicated, these are normally treated non-operatively (with a hanging arm cast, U cast, or U slab). Complete union is not always required since the bone has a dense covering of muscles and blood vessels. The goal of this study was to see if there was a difference between dynamic compression plating (DCP) and intramedullary interlocking nailing in diaphyseal humeral fractures in adults. Methods: It was a prospective study undertaken at MGM Medical College and L.S.K. Hospital in Kishanganj, Bihar, in the department of orthopaedics. During the study period of November 2020 to September 2021, a total of 40 cases were enrolled. The participants in the study were randomly assigned to one of two groups. One closed reduction and internal fixation with antegrade intramedullary interlocking nail-group, and one open reduction and internal fixation with dynamic compression plating-group. Results: We found that the final outcome in between the groups, comparison of DASH score, maximum number of excellent cases were Dynamic compression plating group. i.e. 80.0%, good-13.3%, Fair was 6.7% respectively. In another Interlocking nailing group excellent cases were found 26.7%, good-33.3%, fair- 26.7% and poor was 13.3% respectively. We have found statistically significant p value -0.028. Conclusion: There appears to be a substantial difference in radiological union or rate of union between the two groups; nonetheless, based on complications and functional results, Dynamic compression plating is a good fixation method

Outcome of Dynamic Compression Plate versus Interlock Intramedullary Nail for Management of Humeral Shaft Fractures

Objective: To compare outcomes of interlock intramedullary nails with Dynamic compression plates for the treatment of humerus shaft fractures in terms of hospital stay time and shoulder Impingement. Subjects and Methods: In this comparative study, a total number of 74 patients having age 20-60 years who presented with closed and open Gustilo type I or II in middle third of humerus were included. Study was conducted in Islam hospital Sialkot and and Rajib Tayyip Erdogan Hospital, Muzaffargarh from June-2019 to June-2020. Group A (n=37) patients underwent dynamic compression plating (DCP) for treatment of fractures and group B (n=37) underwent interlocking intramedullary nailing (ILN) for humerus shaft fractures. We noted post-operative hospital stay, shoulder impingement and bone union rate in all patients. Results: The mean of patients included in this study was 42.45 (SD 9.89) years. There were 57 (77.03%) males and 17 (22.97%) females. The mean duration of fracture at the time of surgery was 39.98±7.23 days. Mean hospital stay was 4.72±1.23 days in in group A and 4.89±1.40 days in group B (p-value 0.60). There were 4 (10.8%) patients in group B in whom shoulder impingement occurred but there was no patient in group A with shoulder impingement (p-value 0.04). Complete union occurred in 35 (94.6%) patients in DCP group and in 34 (91.8%) patients in ILN group (p-value 0.64). Conclusion: Both DCP and ILN are associated with high bone union rates. The complications rate of ILN is higher in comparison to DCP group. Keywords: Humerus shaft fractures, dynamic compression plates, interlocking intramedullary nailing.

COMPARATIVE STUDY BETWEEN THE DYNAMIC COMPRESSION PLATING (DCP) AND THE INTRAMEDULLARY INTERLOCKING NAILING IN DIAPHYSEAL FRACTURES OF THE HUMERUS IN ADULTS

AIMS: The aim of our study was to nd the difference between the mean duration of union and functional outcome between the dynamic compression plating (DCP) and the intramedullary interlocking nailing in diaphyseal fractures of the humerus in adults. MATERIALS AND METHODS: From May 2019 to October 2019, 34 patients with diaphyseal fractures of the humerus were treated with compression plating using dynamic compression plate or with intramedullary interlocking nail. The time taken for radiological union in the two groups was compared. After satisfactory radiological union, the functional outcome was assessed by the “Disabilities of Hand, Shoulder and Elbow (DASH) Questionnaire”. RESULTS: All fractures united and a marginal difference was noted in the time taken for union. The functional outcome was better in DCP group compared to interlocking nailing group which was statistically signicant (P= 0.010). The complication associated with interlocking group was more than the DCP group. We are of the opinion that when surgery is opted as a choic CONCLUSION: e of treatment, both the modalities of treatment i.e. dynamic compression plating and interlocking nailing are good as far as union of the fracture is concerned, but considering the number of complications and functional outcome, we opine that dynamic compression plating offers better result than antegrade interlocking nailing with respect to pain and function of the shoulder joint.

Comparison of a 3-hole 4.5-mm Dynamic Compression Plate and a 7-hole 5.5-mm Y Locking Compression Plate for Arthrodesis of the Proximal Interphalangeal Joint in Horses—an Ex Vivo Biomechanical Study

The objective of this study was to compare the biomechanical properties in a single cycle axial loading test and the types of failures in two constructs (a 3-hole 4.5-mm dynamic compression plate (DCP) and 7-hole 5.5-mm Y locking compression plate (Y-LCP)) in equine proximal interphalangeal joint (PIJ) arthrodesis. One limb in each pair was randomly assigned to PIJ arthrodesis using a 3-hole 4.5-mm DCP combined with two transarticular 5.5-mm cortical screws, whereas the contralateral limb was submitted to PIJ arthrodesis using a 7-hole Y-shaped 5.0-mm LCP in conjunction with one transarticular 4.5-mm cortical screw inserted through the central plate hole. Cortical screws were inserted in lag fashion. Constructs were submitted to a single axial load cycle to failure. Construct stiffness, load, and deformation were analyzed. Dynamic compression plate and Y-LCP arthrodesis constructs did not differ significantly and were equally resistant to axial loading under the conditions studied (DCP and Y-LCP group stiffness, 5685.22 N/mm and 6591.10 N/mm, respectively). Arthrodesis of the PIJ using a DCP and two transarticular 5.5-mm cortical screws or a Y-LCP yielded biomechanically equivalent outcomes under the test conditions considered. However, Y-LCP provides less impact in the palmar/plantar bone. Application of Y-LCP with unicortical screws has equivalent biomechanical characteristics of DCP and may be a safe option for PIJ arthrodesis, where potential trauma secondary to applying bicortical screws in the palmar/plantar aspect of the pastern can be avoided.

Satisfactory results were seen in 04 (26.67%) cases in group-I and 03 (20.00%) cases in group-II.&#x0D; Conclusion: On the statistical point of view there was no significant difference between dynamic compression plate group and locking compression plate group for the treatment of mid-shaft fracture radius and ulna.&#x0D; J Shaheed Suhrawardy Med Coll, December 2019, Vol.11(2); 106-109

Functional outcome of dynamic compression plating compared with intramedullary interlocking nailing in closed fracture shaft of humerus in adults.

Objectives: To compare the functional outcome of dynamic compression plating with intramedullary interlocking nailing in closed fracture of the humeral shaft in adults. Study Design: Prospective comparative study. Setting: Department of orthopedics, Civil hospital, Karachi. Period: From 8th February to 7th August 2017. Material &amp; Methods: A total of 82 patients with post-traumatic closed fracture shaft of the humerus were included. Patients were randomly allocated into two groups. Group I was offered Intramedullary Interlocking nail (ILN) and Group II was offered a dynamic compression plate (DCP). The functional outcome was measured by the “Disabilities of Arm, Shoulder and Hand” (DASH) score. Results: The average age of the patients was 32.87±6.65 years. The acceptable outcome was significantly high in DCP group as compared to the ILN group (87.8% vs. 61%; p = 0.005). Conclusion: We conclude that dynamic compression plating is functionally a better technique than interlocking nailing for closed fracture of shaft of the humerus in adults.

Non-locked and locked small fragment straight plates have a similar behavior in buttressing the posteromedial shear tibial plateau fragment: a biomechanical analysis of three different fixations

PurposeThe aim of this study is to compare the biomechanical behavior of three different fixation constructions currently used for buttressing the posteromedial shearing tibial plateau fragment. Our hypothesis is that non-locked implants provide sufficient comparable stability in posteromedial tibial plateau fractures as locked implants.MethodsFifteen left synthetic tibiae from a single manufacturing batch were used to create a posteromedial shear tibial plateau fracture. The fracture was buttressed with three different posteriorly placed five-hole straight small-fragment plate. Five models were fixed with a one-third tubular plate (TTP), five models with a dynamic compression plate (DCP), and five models with a locking compression plate (LCP). All groups were tested to vertical subsidence (Stage 1). In the same experiment (Stage 2), TTP and DCP groups were tested until catastrophic failure. Force versus displacement curves were obtained in the two stages of the experiment.ResultsStage 1 – There was no significant difference in stiffness (p = 0.89), subsidence up to 2 mm (p = 0.38), and energy (p = 0.36) among the three fixation constructions. Stage 2 – Yield load revealed significantly less yield strength for the TTP group as compared with the DCP group (p = 0.048). However, there was no significant difference in maximum load to failure among the TTP and DCP fixation constructions (p = 0.16).ConclusionPlacement of either a locked or non-locked small fragment straight plate to buttress the posteromedial shear tibial plateau fragment has a similar biomechanical behavior. When the implant is positioned to buttress the shearing fragment it maximizes biomechanical stiffness.

Comparative study of functional outcome after internal fixation of comminuted fractures of diaphysis of the forearm with locking compression plate and dynamic compression plate

Introduction: Management of fractures of a forearm over time reflects the evolution of modern Orthopaedics. With the introduction of internal fixation, many surgeons reported encouraging results. The locking compression plate (LCP) and Dynamic Compression Plate (DCP) are newer modalities for fracture fixation of both bone forearm fractures. The study aimed to compare functional outcome after internal fixation of comminuted fractures of diaphysis of the forearm with LCP and DCP. Methodology: It is a prospective type of comparative study involving 30 patients attended orthopedic casualty due to fractures of diaphysis of the forearm. After primary emergency management, a splint was applied; a radiological examination of the affected limb was carried to assess the fracture type. Alternate patients are fixed with LCP and DCP randomization. All patients were personally examined at follow up on the second, fourth, sixth month, and one year. The functional and radiographic results were recorded according to Anderson et al. criteria. Handgrip assessed and compared to the opposite limb. Results: Our study reports that younger patients have shown statistically significant good results compared to older patients (p-value-0.013). Prognosis with sex and type of fracture was not statistically significant. Early fixation gives good result, and it is statistically significant (p-value- 0.008). Even though clinically LCP gives better results compared to DCP it is not statistically significant in single fracture (p-value-0.06), but LCP gives better results in both bones forearm, and it is statistically significant (p-value-0.034). The present study had a union rate of 96.66%, with a mean time of union in the LCP group was found to be lesser in comparison to DCP group. All both bones fractures treated with LCP showed callus formation, and 75% of both bones treated with DCP showed callus formation, and it is statistically significant (p-value-0.05). Overall, the patients were satisfied

Diaphyseal fractures of the forearm in adults, comparative study of dynamic compression plate versus intramedullary nail

&lt;p class="abstract"&gt;&lt;strong&gt;Background:&lt;/strong&gt; Forearm fractures are common nowadays because of road traffic accident. It is important to achieve anatomical reduction of both bone forearm fractures to regain function of upper limb. This study is undertaken to observe functional and radiological outcome using two different surgical modalities like dynamic compression plating (DCP), and intramedullary nailing in both bone forearm fractures and also to indivualize the optimal treatment method for different fracture pattern.&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Methods:&lt;/strong&gt; Our study included 60 patients with diaphyseal forearm fractures in adults presenting to orthopaedic outpatient department. Among 60 patients, 30 patients underwent open reduction and internal fixation by dynamic compression plate and other 30 patients underwent closed reduction/open reduction by square nail after detailed pre-operative evaluation.&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Results:&lt;/strong&gt; In our study average union time in DCP group is 23.39 weeks and square nail group is 28.89 weeks. Union in DCP group was 27 (90%) and square nail group 22 (73.33%). Delayed union in DCP group was 03 (10%) and in Square nail group was 6 (20%), non-union in DCP group was 0 (nil) and in square nail group was 2 (06%).&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Conclusions:&lt;/strong&gt; Open reduction and internal fixation with DCP plates for both bone diaphyseal forearm fractures gives good results with early union rates. We also found that in open fractures and complex fracture like segmental fractures square nailing was better option compared to dynamic compression plate to reduce infection rates, retain periosteal blood supply from soft tissue. Thus we conclude that both implants are equally important and we should prioritize based on preoperative planning.&lt;/p&gt;

A comparative study of internal fixation of forearm fractures using locking compression plate and dynamic compression plate

Background: Fractures of forearm bones are common in direct trauma often while protecting one’s head, road traffic accidents, fall from height and sports activities. Open reduction and internal fixation are the treatment of choice in these cases. Locking Compression Plate (LCP) is a new fixation device in treating these fractures. This study has been carried out to compare the role of Locking Compression Plate (LCP) with Dynamic Compression Plate (DCP) in treating these fractures. Methods: A prospective study was done from September 2017 to March 2019, including forty eight patients with fractures of radius and ulna. In Group I (DCP group), twenty four patients were subjected to open reduction and internal fixation with 3.5 mm stainless steel DCP and non-locking screws. In Group II (LCP group), 24 patients were managed by open reduction and internal fixation using 3.5mm stainless steel LCP and locking head/non-locking screws. All patients were followed up at monthly interval until union. Clinical assessment regarding functional outcome was done at the final follow-up.Results & Conclusion: The mean union time in Group I (DCP group) was 13.67 weeks (range, 8-24 weeks, SD3.67). In Group II (LCP group), the mean union time was 16.25 weeks (range, 12-24weeks, SD3.14). Excellent & satisfactory results were observed in 87.5% cases in Gp I and 91.67% cases in Gp II. On statistical analysis, there was no significant difference in the mean union time and functional outcome in Gp I and Gp II. Both internal fixation devices were equally effective in treating diaphyseal fractures of forearm.

Management of fracture shaft of humerus by dynamic compression plate versus interlocking nail: A prospective comparative study

Background and purpose: Simple humeral shaft fracture can be treated non operatively, with good results in most cases but the non-operative treatment requires a long period of immobilization, which carries a risk of prolonged shoulder joint stiffness and may be inconvenient for the patient. Furthermore, nonunion after conservative treatment of these fractures does occur in up to 10% of the cases and treatment of this condition can be very difficult. Now there is growing interest in treating even simple humeral shaft fractures by dynamic compression plate (DCP) or interlocking nail (ILN) in order to avoid these problems and to allow earlier mobilization and rapid return to work. Methods: 40 patients of fracture shaft of Humerus were included in the study.20 were managed by Interlocking Nail and 20 were managed by dynamic compression plate.Patients were called for follow up after every four weeks after the stitch removal and on each follow up visit, functional and radiological assessment done by predesigned performa. The functional results assessed at the end of 6 months and 1 year postoperatively on the bases of ASES Score (table 2), for 13 activities of daily living requiring full shoulder and elbow movement.Results: At the end of study, 23 (92%) cases in DCP group had acceptable (either good or more than good) results compared to 22(88%) cases of IMN group, having similar results. The mean interval between admissions to surgery, average operating time, duration of hospital study after surgery was less in DCP group while incidence of serious post-operative complications was more in IMN group. There was no statistically significant difference between the two groups with regards the average time taken for radiological union, although the mean radiological union in DCP group occurred 1.6 weeks earlier compared to the IMN group.Interpretation:On the basis of this study, we found that DCP can be considered a better surgical option for the management of fracture of the shaft of humerus in our setting as it offers a shorter admission to surgery interval; shorter operating time and shorter hospital stay after surgery besides the lower incidence of more serious complication like the radial nerve palsy and infection otherwise comparable to IMN in all other variables of interest in our study.

A study of efficacy of locking versus dynamic compression plates for diaphyseal forearm fractures

Fractures of the forearm bones may result in severe loss of function unless adequately treated. Severe loss of function may result even though adequate healing of the fracture occurs 1, 4. Fractures of the forearm present a unique management problem for years. A forearm fracture involving both bones requires open anatomical reduction with stable fixation. 2, 3 various treatment modalities were introduced from time to time and each of them had some edge over the previous one. The forearm represents the critical anatomic unit of upper limb, permitting the effector organ of the upper limb, the hand, to perform multiaxial daily activities of living. Historically, the closed management of forearm fractures has been met with frustration in adults and resulted in poor functional outcome, hence perfect fracture reduction and rigid fixation is mandatory and achieved by plating. 3, 5, 7 The number of forearm fractures is increasing faster than the predicted rate due to increasing number of road traffic accidents, increased incidence of violence, rapid industrialization, and various sports activities. Conservative treatment has resulted in malunion, non-union, synostosis and ultimately poor functional outcome 4, 6, 7. compression techniques have a lower incidence of non-union and are found to hasten rehabilitation, with less joint stiffness.the various modalities of plating have developed each has edge over the other. there are very less studies on indian population this study has taken up to analyse the outcome between two most commonly used plates in forearm shaft fracture treatment i.e DCP (dynamic compression plate) and LCP (locking compression plate). Aims and Objectives of The Study: 1) To study and compare the functional and radiological outcome after surgical intervention by using and open reduction and internal fixation with dynamic compression plating vs locking compression plate in the treatment of closed diaphyseal fractures of forearm. 2) To study and compare the complications associated with these two modalities of the treatment. Materials And Methods: About 60 patients with both bone forearm fractures treated with LCP or DCP in RLJ hospital attached to Sri Devaraj Urs Medical College between maech 2013 to june 2017, will be taken up for the study after obtaining the informed consent. This is a retrospective study with follow up period of 6 months minimum. The functional outcome was assesed according to Anderson scoring system which included evaluation of the movements and the radiological union. Conclusions: Statistically, both LCP and DCP have similar outcomes in the treatment of diaphyseal fractures of both bones forearm. Whereas, LCP group had a faster recovery as compared to DCP group. Thus, we conclude that both LCP and DCP have similar results for the diaphyseal fractures.

Dynamic compression plating versus intramedullary interlocking nail technique: a prospective study in a tertiary care centre

Background:A prospective study was performed to compare the efficacy and the outcome of the dynamic compression plating method and the interlocking nailing method for humeral shaft fractures.Methods: 86 patients undergoing surgery for humeral shaft fractures were categorized into 2 groups of 43 each, undergoing Dynamic Compression Plating (DCP) and Intramedullary Interlocking (IMIL) technique after detailed clinical, physical and radiological history were taken. They were followed up for a total of 36 weeks or till the complete union of the bones, which ever was first.Results:More than 60% of the patients were between 21-50 years of age. Out of the indications for surgery, 49 were fractures with unacceptable reduction and 23 of the fractures were with multiple injuries. Among the DCP group, only 14% of the patients took more than 20 weeks for the union of the fracture while in IMIL group this was further reduced to 9.3%. Union took place in &lt;10 weeks in 48.8% of the patients in the IMIL group and 41.8% in the DCP group. The major complication that was observed in the DCP group was shoulder stiffness which was observed in 16.3% of the cases while in IMIL group, it was only 4.7%. An infection contributed to 11.6% of the complications on the IMIL group but was only 4.7% in the DCP group.Conclusions:Though technically more demanding, our study showed that intramedullary interlocking system to be better than compression plating as it was minimally invasive with lesser blood loss.

Background: In modern era high speed vehicular traffic accidents fractures of the tibial shaft are common injuries among the long bones and mainly affect young adults, i.e. individuals at their peak of physical and work capacity. The present study was a comparative study between interlock nailing and Dynamic compression plating (DCP) in the treatment of fractures of tibia. The purpose of the study was to determine the outcome and comparing the two different modalities of the treatment. Material methods: The Study includes sixty consecutive patients with fracture tibia [ closed and open Gustio & Anderson grade 1 only] treated with Dynamic compression platting and interlock nailing 30 in each group and were assessed clinically and radiologically and followed up to three years. Results: 90% patients had good to excellent results with 10% having fair results and no poor results. In DCP group there were 10 excellent, 15 good and 5 fair results whereas in interlock nailing group 15 patients had excellent, 14 patients had good results and 1 patient showed fair result. Conclusion: We conclude that DCP is a better mode of fixation for proximal and distal tibial facture and interlock nailing is ideal implant in diaphysial and segmental fractures.
