Radiation-free Insertion of Interlocked Intramedullary Tibial Nail in Closed Extra-articular Displaced Tibial Shaft Fractures in an Emergency Setup

Background. Interlocking nailing is considered a gold standard surgical treatment of mid-shaft closed diaphyseal tibial fractures. With increasing exposure of orthopaedic surgeons to radiation, we propose a solution to this health hazard through a study wherein we perform the surgery without any radiation or C-arm exposure. Material and methods. This prospective study was done at GMC Jammu from January 2017 to February 2020 and included 218 patients, with 18 patients having bilateral tibia fractures in the age group 15 to 58 years (mean of 37.6 years), including 63.7% males (n=139) and 36.3% females (n=79). The 236 extra-articular closed tibial mid-diaphyseal fractures were operated on and intramedullary tibial nailing was performed without a single C-arm exposure. Postoperative x-rays were done and reduction assessed by standard acceptable criteria. Results. Among 236 cases in which nailing was done, 227 (96%) patients were successfully distally locked, including 128 (56.3%) locked through the jig and 99 (43.6%) by “hit and trial method.” All cases met acceptability criteria set for management of tibia by nailing. Conclusions. 1.This study strengthens the proof that closed extra-articular diaphyseal fractures of the tibia can be managed by nailing without using the C-arm with excellent results. 2.The C-arm is always available for cases where distal locking could not be achieved. 3. The technique has a great role in centres with limited facilities of intra-operative radiography in emergency operation theatres.

Predicting the Outcome of Open Type IIIC Tibial Fractures Regarding Union, Osteomyelitis, and Amputation

Backgrounds: This study aimed to assess factors that affect union time and complications in Gustilo IIIC tibial fractures.Methods: Patients who presented to our center with IIIC open tibial fractures from January 2000 to October 2020 were eligible for this retrospective analysis. Patient demographics, fracture characteristics, timing, numbers, and type of surgical intervention were documented. Outcomes of interest included union time, occurrence of osteomyelitis, and amputation. Results: Fifty-eight patients were enrolled and grouped by fracture type; eight union on time (13.8%); 27 late union (46.6%); eight delayed union (13.8%); three nonunion (5.2%); and 12 amputation (20.7%). Nine fractures (15.5%) were complicated by osteomyelitis. Union time was prolonged in cases of triple arterial injury, distal third fractures, multiple trauma with Injury Severity Score (ISS) ≥ 16 points, and increased length of bone defect. Additionally, a bone gap > 50 mm, diabetes mellitus, low body mass index, and triple arterial injury in the lower leg were significant risk factors for amputation. A time from injury to definitive soft tissue coverage of more than 22 days was the major risk factor for osteomyelitis. A scoring system to predict union time was devised and the predicted probability of union within two years was stratified based on this score. Conclusions: IIIC tibial fractures involving the distal third of the tibia, fractures with bone defects, triple arterial injury, and multiple trauma with ISS ≥ 16 points demonstrated delayed union, and an effective prediction system for union time was introduced in this study. Early soft tissue coverage can reduce the risk of osteomyelitis. Finally, diabetes and severe bone and soft tissue defects pose a higher risk of amputation.

Retrograde tibial nailing of far distal tibia fractures: a biomechanical evaluation of double- versus triple-distal interlocking

Objectives Retrograde tibial nailing using the Distal Tibia Nail (DTN) is a novel surgical option in the treatment of distal tibial fracture. Its unique retrograde insertion increases the range of surgical options in far distal fractures of the tibia beyond the use of plating. The aim of this study was to assess the feasibility of the DTN for far distal tibia fractures where only double rather than triple-distal locking is possible due to fracture localisation and morphology. Methods Six Sawbones® were instrumented with a DTN and an AO/OTA 43-A3 fracture simulated. Samples were tested in two configurations: first with distal triple locking, second with double locking by removing one distal screw. Samples were subjected to compressive (350 N, 600 N) and torsional (± 8 Nm) loads. Stiffness construct and interfragmentary movement were quantified and compared between double and triple-locking configurations. Results The removal of one distal screw resulted in a 60–70% preservation of compressive stiffness, and 90% preservation of torsional stiffness for double locking compared to triple locking. Interfragmentary movement remained minimal for both compressive and torsional loading. Conclusions The DTN with a distal double locking can, therefore, be considered for far distal tibia fractures where nailing would be preferred over plating.

TO EVALUATE THE FUNCTIONAL OUTCOME OF LOCKING COMPRESSION PLATE FOR FRACTURES AROUND KNEE JOINT(DISTAL 1/3RD FEMUR OR PROXIMAL 1/3RD TIBIA)

Background: To evaluate the functional outcome of locking compression plate for fractures around knee joint (Distal 1/3rd femur or proximal 1/3rd tibia) Methods: This prospective functional out-come study has been conducted on This prospective study has been conducted on 50 patients with Distal 1/3rd femur and 50 patients with proximal 1/3rd tibia Results: According to Modified Mehrotra’s Criteria, the excellent (44.00%) and fair (42.00%) and (14.00%) had poor result Conclusion: Locking compression plate is the optimal tool for many supracondylar fractures of femur and proximal tibia fractures. It provides rigid fixation, where a widening canal, thin cortices and frequently poor bone stock make fixation difficult. Keywords: Femur, Tibia, Locking plate, MIPO, Outcome.
