Purpose: Quadriceps tendon disruption post-total knee arthroplasty (TKA) is rare. Existing reconstruction procedures use allografts or synthetic meshes with varied success. This study evaluates outcomes with autogenous peroneal tendon grafts, a cost-effective alternative, compared to synthetic polypropylene mesh for quadriceps reconstruction., Methods: 16 patients who underwent extensor mechanism reconstruction between 2017 and 2021were retrospectively analysed. Parameters evaluated included type of reconstruction, extensor lag, IKDC (International Knee Documentation Committee) Score and AOFAS-Hindfoot-score (American Orthopaedic Foot and Ankle Society)., Results: At final follow-up, extensor lag for peroneal autograft group was 6.6° ± 1.5 and for synthetic polypropylene mesh group, 7.2° ± 0.7. Both groups improved in IKDC score ( p  < 0.01) AOFAS-Hindfoot-score was comparable for peroneal autograft patients with opposite side ( p  = 0.15)., Conclusions: Autogenous peroneal tendon graft for quadriceps reconstruction could be viable, cost-effective alternative to allografts or synthetic meshes, with good clinical outcomes., Graphical Abstract: Graphical abstract depicting the harvesting of the peronei grafts and their passage through the quadriceps tendon.

Introduction Spinal anaesthesia is frequently associated with adverse effects like maternal hypotension and bradycardia. This effect is due to a decrease in systemic vascular resistance, a decrease in central venous pressure or Bezold-Jarisch Reflex (mediated by 5-HT3 receptors). We aimed to measure the effect of three different doses of prophylactic intravenous ondansetron (5-HT3 antagonists) with a placebo on maternal haemodynamics. Methods A prospective randomised control study was done over 240 parturients, aged 19-35 years. They were randomly allocated into four groups (n=60) Group O4, Group O6, Group O8 and Group S to receive either intravenous ondansetron 4 mg, 6 mg, 8 mg or 0.9% normal saline respectively. Haemodynamic variables (systolic blood pressure [SBP], diastolic blood pressure [DBP], mean arterial pressure [MAP], heart rate [HR]) were recorded at 2-minute intervals for the first 20 minutes and at 5-minute intervals for further 30 minutes. Results A significant decrease in haemodynamic parameters was observed in group S when compared with ondansetron groups at various time intervals (p<0.05). The difference was most significant in groups O6 and O8. Development of nausea and vomiting was significantly higher in Group S compared to ondansetron groups (p< 0.005). The requirement for ephedrine was more in Group S in comparison to ondansetron groups (p<0.0001). Conclusion All three groups of ondansetron showed a decrease in the incidence of hypotension and use of vasopressor but Group O6 and O8 were more effective in attenuating spinal-induced hypotension in parturients undergoing caesarean section., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Vashishth et al.)

Study Design: This study is a prospective clinical study., Purpose: This study aims to evaluate the characteristics of trunk musculature and intervertebral discs by using magnetic resonance imaging in patients with spinal cord injuries (SCIs) with thoracic and lumbar fractures., Overview of Literature: Muscle atrophy is an immediate consequence of SCI and is associated with secondary complications. At present, there are limited clinical data on muscle and disc responses to fractures of the thoracic and lumbar spine., Methods: A total of 51 patients with a mean age of 31.75±10.42 years who suffered traumatic SCI were included in this study. Complete neurological examinations (American Spinal Injury Association grading) and magnetic resonance imaging (MRI) were performed at the time of admission and at 3-6 months after injury to study the neurological status and disc and trunk parameters. The type of management (operative or conservative) was decided on the basis of clinical, radiological, and MRI evaluations, and a robust rehabilitation program was initiated., Results: Disc parameters including disc angle, skin angle, cross-sectional area (CSA), and disc height and trunk parameters (mean trunk width, mean trunk depth, and CSA of the lumbar muscles) decreased significantly (p <0.001) during the first 3 months after SCI. However, improvements were observed in disc and muscle parameters at the 6-month follow-up, but these parameters did not return to normal levels. Neither initial neurological status (complete vs. incomplete) nor type of management (operative vs. conservative) had a significant effect on these parameters., Conclusions: Spinal trauma leads to alterations in the morphology of the vertebral column, spinal cord, intervertebral discs, and paraspinal muscles in the initial phase of injury. The extent of these changes may determine the initial neurological deficit and subsequent recovery. Although this study did not identify any statistically significant effect of neurological status or management strategy on these parameters, rehabilitation was found to result in the improvement of these parameters in the later phase of recovery. Future studies are required to evaluate the exact causes of these alterations and the potential benefits of rehabilitation strategies and to minimize these changes.

Quadriceps tendon is one of the important segment of knee extensor mechanism. Acute ruptures are more common than chronic ruptures and have better outcomes. Chronic ruptures are rare with lot of surgical challenges including tendon retraction, fibrosis, degenerative calcification. We present a rare case of a 48 year old male diabetic patient with history of fall eight months ago and chief complaint of inability to actively extend his left knee. Diagnosis was made clinically and was confirmed radiologically with MRI. Surgical management was done with the use of novel " Chariot Suture Technique ". It involves use of three Krakow whipstitches with Ethibond No. 5 suture across the distal ruptured end of quadriceps tendon and their intraosseous passage through patella in longitudinal fashion followed by tying knot at the distal pole of patella. The formation of Chariot makes the construct stable. At one year follow up patient was actively able to extend the knee with good range of motion. The technique is relatively cost effective, has no donor site morbidity, easy to learn and practice., (© 2020 Delhi Orthopedic Association. All rights reserved.)

Background: To investigate the relationship between neurological deficit and subsequent recovery as assessed by ASIA score and findings of electrodiagnostic study in acute spinal cord injury (SCI) patients., Methods: Thirty-five patients with acute SCI presenting within 48 h of injury were clinically evaluated for the level, extent, and severity of SCI according to the ASIA standards in a tertiary-level care center. Electrodiagnostic studies of bilateral two motor (tibial and peroneal), one sensory (sural) nerves, and five muscles [iliopsoas, vastus medialis, tibialis anterior, gastrocnemius, and extensor hallucis longus (EHL)] were conducted and repeated at 3 months and 6 months., Results: The neurological recovery was highly significant ( p  < 0.001) at 6 months. The difference in mean amplitude was statistically significant ( p  < 0.05) for all the nerves; mean conduction velocity significant for peroneal and sural nerves, and with no significant difference in mean latency. The differences in mean recruitment of motor unit potential (MUP) and mean peak-to-peak amplitude were highly significant ( p  < 0.001). Statistically significant kappa agreement between neurological recovery according to ASIA score and nerve conduction velocity was found for right tibial nerve ( K  = 0.324); electromyography finding of recruitment of MUP with right and left tibialis anterior ( k  = 0.400) and left EHL ( k  = 0.407); peak-to-peak amplitude with right tibialis anterior ( k  = 0.211), right gastrocnemius ( k  = 0.390), and right EHL ( k  = 0.211)., Conclusions: There is a strong relationship between electrodiagnostic findings and ASIA scoring to predict neurological deficit and subsequent recovery after acute traumatic SCI. Serial neurologic evaluation by ASIA score and electrodiagnostic studies may help in designing customized rehabilitation programs for the patients according to the expected neurological recovery; and evaluating future research in the field of SCI with more scientific authenticity., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest., (© Indian Orthopaedics Association 2020.)

Introduction: Monolateral rail fixators are more comfortable to the patients and have a lesser learning curve compared to ring fixators. Guidelines are still lacking for rational use of monolateral fixator for bone transport. This retrospective study aimed to analyze and compare the clinico-radiological outcomes of monolateral fixator in infected non union of tibia based on bone gap quantification., Materials and Methods: This retrospective study included 35 patients of post traumatic infected osteocutaneous defects of tibia operated from May 2013 to May 2016. Group I having bone gap of 6 cm or less ( n  = 20) and group II with > 6 cm bone gap ( n  = 15). The mean age was 29.56 (range 18-62) years in group I and 29.67 (range 20-65) years in group II. The mean bone gap was 4.62 (2-6 cm) in group I and 7.6 cm (6.5-10 cm) in group II ( P  < 0.00001, Mann-Whitney test). The results were assessed by Association for the Study and Application of the Method of Ilizarov (ASAMI) criteria., Results: Union was achieved primarily in 90% ( n  = 18) cases in group I and 73.34% ( n  = 11) cases in group II. The bone result was excellent, good, fair/poor in 14, 5, 1 in group I; and in 4, 6, 5 in group II, respectively ( P  = 0.020, Chi-square test). The functional results were excellent, good, fair/poor in 15, 4, 1 in group I; and 5, 8, 2 in group II, respectively ( P  = 0.0479, Chi-square test)., Conclusion: We recommend use of monolateral fixator in patients with infected diaphyseal non union of tibia with bone gap ≤ 6 cm. Use of monolateral fixator in patients with bone gap > 6 cm is associated with higher incidence of residual problems and complications., Competing Interests: Conflict of interestThe authors declare that there is no conflict of interests regarding the publication of this paper., (© Indian Orthopaedics Association 2020.)

Background: There has been a lot of research done on Ilizarov's limb lengthening; however, very few publications focus on the quantitative assessment of the distractional bone regeneration in tibial and femur lengthening. Data regarding quality of the bone after lengthening are needed to consider the time of frame removal and develop a rehabilitation program., Materials and Methods: Computed tomography (CT) assessment of a parent bone was performed on 136 patients with limb length discrepancy and bone deformity of various etiologies before and after lengthening. Transosseous osteosynthesis technique with the Ilizarov's external fixation was used for limb lengthening and deformity correction in all the cases. A 64-slice scanner was used for CT assessments. Specific Roentgen-negative units of the Ilizarov apparatus and techniques for interpreting CT findings were employed for artifact-free densitometric assessment., Results: Cortical density of the femur and tibia in patients with limb length discrepancy and bone deformity of various etiologies was shown to have differences as compared to the contralateral limb. The lengthening process was accompanied by decreased cortical density of the segment being lengthened, and the decrease in the density was greater in the areas adjacent to the distractional bone regeneration. The cortical structure underwent characteristic changes. Osteonal density of the cortical bone was higher in the norm and at long term followup as compared to the density of external and internal plates., Conclusion: Cortical bone of the femur and tibia in patients with limb length discrepancy and bone deformity of various etiologies showed various preoperative local densities of external, internal, and osteon layers. The cortical bone demonstrated heterogenic structures with resorption areas of various magnitude and density, with minimal values at the boundary with regenerate bone during distraction and fixation with frame on and at short-term followup. Complete organotypical restructuring of the bone was shown to occur at a 1-to-3-year followup depending on the etiology of the disease and amount of lengthening performed., Competing Interests: There are no conflicts of interest.

Introduction: Trochanteric pressure ulcers (PrUs) are difficult to treat and are often complicated by infection spreading to the hip joint. We review three cases from India where proximal femoral resection and pedicled Tensor Fascia Lata (TFL) flapping was used in the management of infected deep trochanteric ulcers communicating to the hip joint., Case Presentation: Three patients had a total of four trochanteric PrUs communicating to the hip joint. Proximal femoral resection along with radical debridement of the pressure ulcer (PrU) was the first step in our surgical protocol. Serial debridements were performed to make the resulting cavity healthier and ready for the subsequent flap surgery. TFL flapping was done to cover the raw area of the PrU and the donor site was closed either primarily or with a split skin graft. All patients were males with AIS A spinal cord injury (SCI) and stage 4 PrUs in the trochanteric region. One patient had bilateral trochanteric ulcers. There was complete healing of all PrUs with improvement in wheelchair mobility, and general health., Discussion: PrUs are a common complication of patients with SCI and are often considered one of the most neglected issues of health care delivery in India. Proximal femoral resection with pedicled TFL muscle flap is a versatile and reliable procedure for the coverage of recalcitrant trochanteric PrU with hip joint involvement. Minimal donor site morbidity occurs., Competing Interests: The authors declare that they have no conflict of interest.All procedures performed in this study were in accordance with the ethical standards of institution, the governmental regulations and with the 1964 Helsinki declaration and its later amendments.

Osteochondroma is the most common benign tumour of bone seen in 3% of the general population. Complications such as neurological compromise, skeletal defects, vascular lesions, and compartment syndrome occur in about 4% of osteochondromas. We bring forth the case of a 16-year male who presented with the complaints of swelling in calf region associated with symptoms of claudication and paraesthesias in leg after exertion and absence of any such complaints at rest. Radiographs revealed a bony pedunculated mass originating from the posterior tibial metaphyseal region causing compression of posterior soft tissue structures. Excision biopsy of the mass was done by posterior approach with an L-shaped incision. The aim of this case report was to draw attention to the early signs of vascular compromise by osteochondroma in this region in order to prevent serious complications in future by early decompression.

Background: Salvage of large, infected bone defects in tibia poses a formidable problem. The present prospective study aimed to evaluate radiologic and functional outcome of ring fixator in infected, large (≥6 cm) bone defects of tibia treated with distraction osteogenesis., Materials and Methods: The study included 35 patients (30 males and 5 females) who had minimum of 6 cm gap after radical resection of necrotic bone and presence or history of active infection. Mean age was 36.1 years. Mean bone gap was 7.27 cm. Mean follow-up period was 25.4 months., Results: Fracture united primarily in 17 cases and after fixator adjustment with freshening of fracture margins in 15 cases. Fixator adjustment with bone grafting was done in one patient to achieve union. One patient had nonunion and another had amputation. The bone result was excellent, good, and poor in 19, 13, and 3 patients, respectively. The functional results were excellent, good, fair and failure in 14, 19, 1, and one patient, respectively. 24 patients had superficial pin tract infection and 18 patients had ankle stiffness., Conclusion: Ring fixator systems reliably achieve union in infected, large bone defects of tibia and help in treating infection, shortening, bone and soft tissue loss simultaneously. We advocate early freshening of fracture ends and removal of interposed soft tissue at docking sites to achieve union. Superficial pin tract infection and ankle stiffness are common problems in managing large tibial defects. But good to excellent functional outcomes can be achieved in majority of patients.

Introduction: Tuberculosis tenosynovitis of the wrist and hand is an unusual condition. It mimics a number of other clinical conditions such as ganglion, De quervan's disease, carpal tunnel syndrome, granulomatous gout, neurofibroma, and haemangioma., Case Report: We present case of 58-year-old male patient with swelling over thenar region of left hand where the initial fine needle aspiration cytology (FNAC) report suggested diagnosis of ganglion/synovial cyst, but the patient did not improve with conservative treatment. FNAC was repeated which showed granulomatous inflammation consistent with the clinical diagnosis of tuberculosis and antitubercular therapy for 9 months was given. Swelling disappeared and normal range of movements was attained in adjacent joints at final follow-up of 12 months from initiation of antitubercular treatment (ATT)., Conclusion: The literature on the management of tubercular tenosynovitis has mostly incorporated surgical method as one of the first-line treatments. We report an unusual case, where the tenosynovitis of wrist completely responded within 12 months of ATT without any need of surgical treatment., Competing Interests: Conflict of Interest: Nil

Background: Displaced fractures of the acetabulum are best treated with anatomical reduction and rigid internal fixation. Adequate visualization of some acetabular fracture types may necessitate extensile or combined anterior and posterior approaches. Simultaneous anterior iliofemoral and posterior Kocher-Langenbeck (K-L) exposures with two surgical teams have also been described. To assess whether modified Kocher-Langenbeck (K-L) approach can substitute standard K-L approach in the management of elementary acetabular fractures other than the anterior wall and anterior column fractures and complement anterior surgical approaches in the management of complex acetabular fractures., Materials and Methods: 20 patients with transverse and associated acetabular fractures requiring posterior exposure were included in this prospective study. In 9 cases (7 transverse, 1 transverse with posterior wall, and 1 posterior column with posterior wall), stabilization was done through modified K-L approach. In 11 cases (3 transverse and 8 associated fractures), initial stabilization through iliofemoral approach was followed by modified K-L approach., Results: The average operative time was 183 min for combined approach and 84 min for modified K-L approach. The postoperative reduction was anatomical in 17 patients and imperfect in 3 patients. The radiological outcome was excellent in 15, good in 4, and poor in one patient. The clinical outcome was excellent in 15, good in 3 and fair and poor in 1 each according to modified Merle d'Aubigne and Postel scoring system., Conclusion: We believe that modified K-L approach may be a good alternative for the standard K-L approach in the management of elementary fractures and associated fractures of the acetabulum when combined with an anterior surgical approach. It makes the procedure less invasive, shortens the operative time, minimizes blood loss and overcomes the exhaustion and fatigue of the surgical team.

Introduction. Although fractures of humeral shaft show excellent results with conservative management, nonunion does occur. Case Report. We bring forth the case of a young male with a 1.5-year-old hypertrophic nonunion of the humerus mimicking an enchondroma. The initial X-ray images of the patient appeared to be an enchondroma, which only on further evaluation and histopathological analysis was diagnosed conclusively to be a hypertrophic nonunion. Discussion. Enchondromas are often incidentally diagnosed benign tumours. It is however not common to misdiagnose a hypertrophic nonunion to be an enchondroma. We present this case to highlight the unique diagnostic dilemma the treating team had to face.
