A comparative study of analysis of functional outcome of intra articular distal radius fractures treated with dynamic external fixator and locking compression plate.

Results: After proper analysis and doing statistical comparison, we got p- value of 0.568 for functional outcome and 0.468 for anatomical outcome which is considered insignificant. (significance of p value determined as <0.05). But with regard to individual parameters in the scores, we got significantly better results in the values of volar tilt, radial inclination and intraarticular step off in volar locking compression plate than dynamic external fixator. Regarding complications, among Ex fix group, 3 patients had superficial pin tract infection, one patient had deep infection, one had malunion and one had pin bending complications and among LCP group one had screw penetration into joint space and one had secondary collapse of the fracture.

Comparative study on the analysis of functional outcome in distal radius articular fractures treated by closed reduction through bridging external fixator augmented with K-wires and Volar-locking plating

The palmar ulnar cortex is richly embedded bone with the greatest trabecular density. The success of internal fixation techniques thrives on the fact that this superior quality thick bone, found in even the osteoporotic cadaver specimens. Distally, the radius attains a roughly trapezoidal shape. The radial styloid rotates palmarly 15 degrees off the axis of the radius. This makes it difficult to keep in reduced position from a dorsal approach. The lunate facet of the radius harbours the strongest bone. The line of force passes down the long finger axis, traversing through the capitolunate

Comparative study of functional outcome of supracondylar fractures of femur treated with distal femur locking compression plate with that of supracondylar nail

Comparative study of functional outcome of supracondylar fractures of femur treated with distal femur locking compression plate with that of supracondylar nail

of the GSH nail is its intraarticular starting point, which allows it to be used for very distal fractures. Closed placement with indirect reduction of the fracture minimizes soft tissue and periosteal damage, thus preserving vascularity. Less surgical dissection is required resulting in less blood loss, less muscle damage and less postoperative discomfort. Distal femoral fractures with hip implants or with total knee replacement with an open notch design also can be effectively treated with retrograde nails. It can also be used in cases of floating knees, for simultaneous fixation of tibial and femoral fractures, through the same incision. The design of the retrograde supracondylar nail is associated with potential disadvantages as well. The intra articular portion will lead to knee stiffness, patello-femoral degeneration and synovial metallosis. The proximal tip of the nail generally lies in the mid or distal femoral shaft, creating a stress raiser 21 .

Analysis of Factors Affecting the Functional Outcome of Intra Articular Distal Femoral Fractures

Analysis of Factors Affecting the Functional Outcome of Intra Articular Distal Femoral Fractures

necessary preoperatively evaluation of the cardiac status with ECG, Chest x-ray, and 2D ECHO if necessary 2D ECHO was done. For the posted case of distal femoral fracture for surgery, internal fixation was done through the lateral incision just anterior to the intermuscular septum, for condylar buttress plate and locking plate. All cases were done under spinal anesthesia in the operation theatre of NIMS. Image intensifier was used where ever necessary. The implants used are Condylar Buttress Plate [CBP], Locking Compression Plate [LCP], Cancellous Screw Fixation [CSF] and external fixator and Ilizarov fixator. Both cortical and cancellous bone grafting was done from iliac crest and fibula for severely comminuted metaphyseal and Intraarticular fractures and all Bone grafting were done along with primary operation.

Comparative analysis of functional outcome of distal femur fractures treated with Locking Compression Plate fixation and Dynamic Condylar Screw fixation

Comparative analysis of functional outcome of distal femur fractures treated with Locking Compression Plate fixation and Dynamic Condylar Screw fixation

In our study, 25 cases of distal femur fracture were operated with Open Reduction with internal fixation with Dynamic Condylar screw and Locking compression plate. 10 patients of distal femur fractures operated with DCS and 15 patients were operated with locking compression plate. Patients were followed up every 3 weeks till fracture united and thereafter at 3 months, 5 months and 1 year. The minimum follow up period in our study was 3 months and maximum follow up period was 12 months. Clinically, tenderness at fracture site, knee pain, limb length discrepancy, range of movements, any varus or valgus deformity were assessed at each follow up. The results were analyzed with standard anteroposterior and lateral radiographs. Clinical and radiological signs of union were analyzed at each follow up. The fracture was said to be radiologically united if callus was seen in at least 3 cortices in anteroposterior and lateral views. The functional outcomes were analyzed using scoring system of HOSPITAL FOR SPECIAL SURGERY.

Original Article Results of type C fractures of distal radius treated by volar locking plate (VLP), an observational comparative study

Original Article Results of type C fractures of distal radius treated by volar locking plate (VLP), an observational comparative study

the impacted lunate facet fragments and ke- eping adequate stabilization is the key issue that deserves surgeons’ greatest attention. In this study, we applied the traditional Henry or extended approach so as to obtain maximum exposure of the articular surface to capture and fix the lunate facet fragments. For frac- tures with bone loss after fracture reduction in fractures with intra-articular multifragments and metaphyseal comminution, we recommend autologous iliac bone to fill the gap or buttress the small impacted luante facet fragments. In addition, for lunate facet fragments of dorsal displacement that were unable to capture and fix by single VLP, we applied auxiliary kirschner wires or external fixator to stabilize the frag- ments. Despite this, the mean values of articu- lar step-off was 0.6 mm (sd, 0.9 mm) and there were 5 cases (23.8%) of significant articular step-off (>2 mm) found at the last follow-up, both of which were higher that of previous stud- ies [13, 21, 22]. Primarily, we attributed this deviation to the greater severity of fractures, with C3 accounting for 76.2% in the DP group in this study. In contrast, the sample in their stud- ies was type B3 or type B and C [22]. There- fore, multifragmentary fractures with impacted lunate facet significantly increased the difficul- ty in reduction and fixation during surgery. In addition, the specific anatomy of volar-ulnar corner of lunate facet made it impossible for VLP to provide similarly adequate stability for scaphoid and lunate facet [23-25]. Therefore, improvement of technical skills for fixation of small lunate facet fragments and innovative design of implants might be the future research subjects.

was checked in the C-arm in antero-posterior and lateral views (Fig. 1). Reduction was achieved via manual traction and closed reduction method in all cases. Sterile betadine dressing of the pin tract site was performed. A below- elbow plaster of Paris slab was applied in all patients for 1 week. The external fixator was removed in all patients after 8 weeks. No extra wire was used in any patient since we were able to achieve reduction in fracture by use of pins only.

Functional outcome of communited intra articular distal radius fractures managed by fragment specific fracture fixation: A Prospective study.

There are many treatment options for distal radius fractures.Undisplaced stable fractures can be treated conservatively with casting.Unstable fractures can be treated with percutaneous K wire fixation.Communited fractures can be treated with external fixation.But there is a period of immobilisation for the wrist joint when treated with external fixation which can lead to wrist stiffness (18) .There are dynamic external fixators available to treat communited distal radius fractures but the reduction achieved with this method is frequently not satisfactory.Furthermore reduction of intra articular fragments could not be achieved to a satisfactory degree with an external fixator.

Functional outcome of intra-articular fractures of distal radius using external fixator: A long term study

Functional outcome of intra-articular fractures of distal radius using external fixator: A long term study

confirm the observation by others that anatomic restoration of the articular surface is a critical part of the operative treatment of intra-articular fractures of distal radius and has a direct influence on the final outcome. Bradway et al.19 and Knirk and Jupiter showed that >2 mm of articular incongruity (step-off) was associated with a high prevalence of post-traumatic arthritis and poorer functional results. The treatment of distal radius fractures has undergone changes owing to the advances in technology. Improved imaging methods providing better understanding of fractures and elucidation of the effects of injury type on fracture formation and factors leading to instability have given way to new fixing methods and materials appropriate for the fracture. Distal radius is important in the kinematics of radiocarpal and radioulnar joints. Hence, anatomical reduction of the articular surface, stable fixation, restoration of the radial length, volar angulation and radial inclination are the prerequisite for good clinical outcome. All this reduces the incidence of post-traumatic osteoarthritis and allow early functional rehabilitation. The degree of disability after distal end radius fracture has been seen to correlate with the amount of residual deformity. Treatment options include closed reduction and pinning, bridging and non-bridging external fixation and open reduction with dynamic compression plate (DCP), precontoured locking and non locking plates and screw fixation through a variety of approaches 20 . Failure to reduce intra-articular fractures of the distal radius predisposes to pain, restricted movement and degenerative arthritis. Malposition is related to the radial height, radial angle, volar tilt and the accuracy of intra-articular reduction. In the treatment of comminuted distal radius intra articular fractures, surgeons may encounter serious complications such as difficult reduction and stabilization, loss of reduction, limitation of range of movement, post traumatic arthritis of the wrist. A brief classification should be made before treating the distal radial fractures.

Management of Intra Articular Fractures of Distal Radius with Volar Locking Compression Plate – Midterm Outcome Analysis

Management of Intra Articular Fractures of Distal Radius with Volar Locking Compression Plate – Midterm Outcome Analysis

The fractures of the distal radius are very common injuries accounting for about 8 to 17% of fractures seen the emergency room. The purpose of this study was to evaluate functional and radiological outcome of patients with intra articular distal radius fractures treated with a volar locking compression plate. As with an increase in life expectancy there is an increase in the incidence of these fractures as well. There appears to be a bimodal distribution among these fractures where the younger group falling prey due to high velocity injuries like road traffic accidents and the older group due to a trivial fall mainly due to senile osteoporosis.

Short term analysis of the Functional and Radiological outcome of distal femoral fractures fixed with locking compression plate by Minimally Invasive Plate Osteosynthesis (MIPO) technique: A prospective study

Materials and methods: 20 patients with distal femur fractures were evaluated in between July 2011 to November 2013. Radiographs of knee were taken in AP & Lateral views. AO/Muller type B and C3 were excluded from the study. All the patients were operated under spinal/epidural anaesthesia and the patient position was supine with knee in 60-70 degrees flexion. Distal femur was exposed using modified lateral approach (minimally invasive) and the fracture was reduced by indirect reduction techniques. We used locking compression plate to fix the fracture. Post operative radiographs were taken to assess the reduction and implant position.post operative rehabilitation was started from the 1 st post operative day. Patients were followed up at every 4-6 weeks interval to assess fracture union, limb length, alignment, knee range of movements and functional outcome. Hammer et al grading was used to assess union and the knee society scoring system was used to assess the functional outcome.

Treatment of reducible unstable fractures of the distal radius: randomized clinical study comparing the locked volar plate and external fixator methods: study protocol

Treatment of reducible unstable fractures of the distal radius: randomized clinical study comparing the locked volar plate and external fixator methods: study protocol

The linear external fixator to be used will be a radiotransparent bar with two pin fastening platforms, with one platform being proximal on the radius and the other platform distal on the second metacarpal, offered by Synthes (code – 03.304.220S). Four threaded self-drilling pins will be used with the proximal platforms that are 4.0 mm in diameter and the distal platforms that are 2.5 mm in diameter. Osteosynthesis with an external fixator will be achieved by the following surgical technique: closed reduction of the fracture by the reduction technique employing traction and contraction manipulation; confirmation of reduction with the image intensifier; a longitudinal incision of 1.5 mm in the dorsal aspect of the forearm and 8 cm proximal from the wrist joint on the longitudinal axis of the radius; exposure of the dorsal cortex of the radius by blunt dissection, introduction of the soft tissue protector positioned at a right angle to the coronal plane of the forearm; introduction of two 4.0 mm self-drilling Schanz pins with a T-handle; double 0.01 cm incisions over the dorsal aspect of the diaphysis of the second metacarpal with a 1 cm spacing between them; dissection and exposure of the dorsal cortex of the metacarpal; placement of the soft tissue protector at a right angle to the coronal plane of the hand; introduction of two 2.5 mm self-drilling Schanz pins, with a technique similar to that for the proximal pins, in the diaphyseal region of the second metacarpal. Should the fracture be intra-articular, this surgical technique may be combined with percutaneous fixation with 1.5 or 2 mm K-wires. Where dorsal comminution is present, a bone graft may be performed with bone removed from the iliac. Open reduction with volar approach and volar locked plate.

Locking compression plating for distal femoral fractures: A Short Term Outcome Analysis

Locking compression plating for distal femoral fractures: A Short Term Outcome Analysis

a cleft palate and was made out of molded gold. The late 1880's brought the next major change in bone plating; surgeons began burying the bone screws below the skin. There were many designs and ideas that developed over the next 70 years. Unfortunately, malunions, nonunions and bone infections were issues due to lack of sterile techniques, and bone plates that were biomechanically unable to provide rigid fixation. Robert Danis (1880-1962) developed the ideas of compression plating and experimented with many different designs during his lifetime. Modern bone plating started in the 1950's when a group of 15 surgeons lead by Maurice Muller formed AO/ASIF (Albeitgemeinshaft fur osteosynthenfragen/ Association for the study of internal fixation) to improve the principles of bone plating. AO remains purely a medical organization to advance the study of fracture treatment while Synthes is the commercial arm of the AO.

A locking compression plate as an external fixator for treating infected nonunion of the humeral diaphysis

A locking compression plate as an external fixator for treating infected nonunion of the humeral diaphysis

The use of an LCP as a definitive external fixator did not seem to adversely affect bone healing. We note that an LCP is usually only applied as a temporary external fixation [9, 15]; after resolution of the infection or heal- ing of the wound, definitive internal fixation is generally performed, probably due to concerns regarding the po- tentially insufficient strength of an external locking plate. Kanchanomai et al. [21] designed a biomechanical test of tibial fracture externally fixed with an LCP, and re- ported that an increased distance between the bone and the implant significantly decreased the construct stabil- ity; however, all models were cyclically loaded beyond 500,000 cycles without any failure of the LCP [21], and so failure of the LCP is unlikely to be a critical issue in clinical cases. This is supported by previous research; one study reported that eight open tibial fractures healed after only first-stage treatment due to patients’ refusal of second-stage treatment [16], a series of 12 tibial injuries treated using an LCP as a definitive fixator resulted in union with no loosening or failure of implant in all cases [12], and 31 patients with infected nonunion or open fracture mainly of the upper extremity treated using an AO-plate as an definitive external fixator (via the same principle as an LCP) resulted in healing of both the in- fection and the nonunion [22]. Similarly, in the present study, the outcome was satisfactory in all seven cases of infected nonunion of the humeral diaphysis treated with an LCP applied as definitive external fixation.

Analysis of functional outcome of Muller's Type A and C fractures distal femur using locking compression condylar plate: A Prospective study

Fractures of the distal femur are complex injuries. They can produce significant long term disability. They account for 7% of all femoral fractures. If hip Fractures are excluded, 31% of femoral fractures involve distal portion. Although open reduction and internal fixation with plate and screws has Become a standard method of treatment for many types of fractures, the Management of comminuted, intra articular distal femoral fractures still remains Complex and challenging to the orthopaedic surgeon. Many of these fractures are the result of high energy trauma which generates severe soft tissue damage and articular and metaphyseal communition.

range 9%-98%) of the surface area of medial condyle of proximal tibia. Higgins et al., confirmed the fact and showed that the fragment occupied 25% of the total tibial articular surface. Usually it is a split fracture with more than 5mm displacement rather than a depression even in osteoporotic bones. As a result there have poor outcome after conservative treatment. It is often associated with injury to anterior cruciate ligament. Open reduction and internal fixation with buttress plating is the recent recommendation for these fractures. Since the fragment is postero-medial, the direct posterior approach placed the neurovascular structures at risk. Approaching the fragment anteriorly also posed risks in the form of extensive dissection of the medial capsular structures and needed tibial tubercle osteotomy for better exposure. In a study by Hsieh et al., they used anteromedial approach and advocated it since there is no risk of neurovascular injury or flexion contracture of the knee 30 . This approach involved erasure of semi-membranosus and semi-tendinosus tendons. The medial collateral ligament was also easily injury. Since the major blood supply of knee is from the medial side there is increased risk of soft tissue devitalisation in already compromised soft tissue from high velocity injury. In 1960s, posterior approach to knee involving dissection of the neurovascular bundle was introduced by Trickey 31 . Since it was a highly demanding procedure, many had complications.

Analysis of Functional and Anatomical Outcome of Management of Unstable Extra-Articular Distal Radius Fracture with Plaster Immobilization and with External Fixation

Fractures of the distal radius though common and appear simple, affect the function of the wrist considerably. It is the commonest fracture seen in the outpatient department and most are treated with plaster immobilization. Most of these fractures are unstable resulting in loss of reduction and hence malunion, altered wrist kinematics, poor range of motion and early arthritis.
