Result of Subtrochanteric Femoral Fracture Fixation by Intramedullary Interlocking Surgical Implant Generation Network (SIGN) Nail.

Treatment of sub-trochanteric femoral fractures is a challenge to orthopaedic surgeons. High incidence of fixation failure and nonunion is due to thick cortical bone deserves special consideration of surgical treatment. Intramedullary nail by Surgical Implant Generation Network (SIGN) shows promising results in comparison to conventional fixation method because of its better strength, accuracy and surprisingly better results in infection and non-union. The aim of this study was to assess the rate and time taken for union of fractures by SIGN nail and determine peri-operative parameters. This prospective study was conducted from July 2016 to June 2018 at National Institute of Traumatology and Orthopaedic rehabilitation (NITOR) through non randomized purposive sampling. Total 31 patients, aged above 18 years irrespective of sex with closed subtrochanteric fractures were included. Patients with pathological fracture, multiple injuries were excluded from the study. Union status evaluated by Radiographic Union Score for Tibial (RUST) fracture where antero-posterior and lateral radiographs (X-ray) based assessment of healing of the four cortices done. The individual cortical scores were added to give a total score 4 being the minimum indicating fracture is definitely not healed and 12 being the maximum score indicating that the fracture is definitely healed. The mean age of the patients was 42.61±19.59 years with range 18-80 years. Majority of patients were male (68%) and most of injury (68%) due to road traffic accident with common fracture were Seinsheimer type III (51.6%). Average hospital stay period was 16.39 days and average follows up 42.39 weeks (24-48 weeks). Time taken for union was 14.16 weeks (11-28 weeks). According to RUST scores fracture union rate 93.55% with delayed union 6.45% and no nonunion. There was one patient with superficial wound infection, one unaccepted shortening and with no implant failure. This study concludes that intramedullary interlocking SIGN nail is a safe and reliable implant for the treatment of subtrochanteric femoral fractures.

Management of Neglected Rupture of Tendoachilles with Long Gap by Flexor Hallucis Longus Tendon Transfer.

The tendo achilles is one of most important tendon in human body which often injured through direct trauma or indirect stress on a weakened tendon. Longer the duration after injury the injured parts likely to move apart, fibrosis and degeneration leading to difficulty in repair or reconstruction. Usually a phase of 4 weeks or more without specific treatment is regarded as chronic or neglected rupture. Different authors described many management protocols about the tendo achilles rupture but there is no procedure of choice for neglected rupture with long gap. Prospective case series of 21 patients of neglected tendo achilles rupture with long gap treated with flexor hallucis longus tendon (FHLT) transfer was taken for study from January 2019 to December 2020 in Mymensingh Medical College Hospital, Bangladesh. Average age of patients was 39.47 years with range 22-65 years. Fifteen (15) cases of traumatic rupture in this study with average age 32.66 years and pathologic 6 cases with average age 56.5 years were recorded. We grafted FHLT from channel by incising Henry's knot. Krackow et al.'s technique was followed for tendon mobilization and bone fixation. We made procedure simpler and cheaper; instead of using interference screw the sutured tendon pulled through the heel and anchored over rubber tube or button by Cole method. Post-operative complications were less with one patient with superficial infection which eventually recovered 3 cases of mild pain and 2 cases of numbness. Questionnaire for surgical outcome measure are satisfactory in 19 patients (90.47%). Final follow up AOFAS score at 6 month (91.61±5.41) was highly significant (p<0.001) in comparison to preoperative score (38.71±9.78). These are comparable to other study. Above mentioned scores indicate the reliability of the surgical system. But our study is a prospective case series with minimum cases. To establish the best procedure for neglected tendo achilles rupture with long gap we recommend further study with larger group and Randomized Controlled Trial (RCT) study among different procedure.

Clinical Outcome on Comminuted Femoral Shaft Fractures in Adults Treated by Minimally Invasive Plate Osteosynthesis (MIPO) with Locking Plate.

Intramedullary nailing is a pillar in the treatment of femoral shaft fractures. But it is not possible in all cases especially in comminuted fractures. This study has been designed to explain the importance of Minimally Invasive Plate Osteosynthesis (MIPO) with the locking plate in the treatment of comminuted Femoral Shaft Fracture. Twenty (20) such patients were treated by MIPO and analysis has been done in this study to get fruitful result and to find out the effectiveness of this procedure who were admitted at Mymensingh Medical College Hospital, Mymensingh, a tertiary level hospital of Bangladesh from February 2018 to January 2019. Mean age of the patients were 49.20±14.41 years. Based on AO classification, there were 4, 8 and 8 patients belong to type A, B and C respectively. The union period for all the patients was in between 12 to 14 weeks. The mean union period was 12.90±1.997 weeks. Mean follow up period was 19.70±2.77 weeks. Mean full weight bearing period was 16.50±1.10 weeks. In Thoresen scoring system excellent result was 9(45%), good result was 10(20%) and fair result was 01(5%). Mal-alignment happened in two cases. However, delayed union and broken screws were found in two cases each of which was treated accordingly. Comminuted Femoral shaft fracture with MIPO procedure is more effective treatment than intramedullary nailing. Furthermore, mal-alignment is the basic complexity that must be taken away intraoperatively.

Core Decompression with Non Vascularized Fibular Graft as Modern Surgical Treatment of Early Hip Avascular Necrosis.

Cellular death of bone due to impairment of the blood supply leading to collapse resulting in pain, and loss of joint function is known as avascular necrosis (AVN). The head of femur is the most common bone affected by avascular necrosis followed by talus and scaphoid. We evaluate the results of core decompression with non-vascularized fibular graft in avascular necrosis of femoral head. This quasi experimental study was done at Mymensingh Medical College Hospital, Dhaka Medical College Hospital and some other private hospitals of Bangladesh. The study includes patients who underwent core decompression and non-vascularized fibular grafting in avascular necrosis of femoral head from January 2017 to December 2018. In this study we evaluated total 20 patients and majority of the patients belongs to the group of 20-30 years. Out of 20 patients, 8 of them were unilaterally involved rest 12 had bilateral involvement. Out of 24 hips of bilateral involvement 4 were grade III and IV (Ficat and Arlet classification) therefore not included in the study. So, we study 28 hips only. The average success rate was 90% after core decompression and non-vascularized fibular bone grafting. Harris hip score of 60 on presentation had poorer outcome. Patients with less than 80 degrees of flexion had poorer outcome.

Outcome of Danis-Weber Type-B ankle fracture treated by Pre-contoured Distal Fibular Locking Plate.

Danis-Weber type-B ankle fracture is one of the most common injuries in young and active individual. This fracture offers a considerable challenge to orthopedic surgeon. Though there are several options for treating such type of fracture, ORIF by Pre-contoured Distal Fibular Locking Plate is the preferred option in the recent years. This descriptive type of observational study was performed from July 2017 to June 2019 in NITOR. Thirty (30) patients, 22 male and 8 female with an average age of 39 years with Danis-Weber type-B ankle fracture underwent ORIF by Pre-contoured Distal Fibular Locking Plate for fractured fibula and ORIF by 4.0mm cannulated cancellous screw for fractured medial malleolus. All the patients were initially managed by analgesic and short leg posterior slab. Average follow up was 24 weeks. Final outcome was assessed by AOFAS score. The main cause of injury was RTA (56.67%). Mean operation time was 1.2 hours. Mean duration of Hospital stay was 16.43±1.73 days. Superficial infection was in 3.33% and skin necrosis in 3.33% patient. Mean duration of radiological healing was 12.73±0.39 weeks. At final follow up, mean dorsi flexion was 10.93°±0.357° and plantar flexion was 50.93°±0.357°. Ninety percent (90%) patient had no difficulties in walking on any surface; 96.67% patient had stable ankle hind foot; 86.67% patient had good. Ten percent (10%) had fair and 3.33% patient had poor alignment of foot. The mean score in this study was 88.67±2.31. Satisfactory outcome was observed in 86.67% patients and 13.33% had unsatisfactory results. On the basis of results in the present study, it can be concluded that treatment of Danis-Weber type-B ankle fracture by Pre-contoured Distal Fibular Locking Plate is an effective and reliable method.
