Effect of Preoperative Oral Carbohydrate Intake on Perioperative Hyperglycemia in Indian Patients Undergoing Hip Fracture Fixation.

Objective: Preoperative fasting leads to a catabolic state aggravated by surgical stress. This leads to poor patient outcomes. This study aimed to determine the effect of preoperative oral carbohydrate administration on perioperative hyperglycemia and patient comfort. Methods: This prospective, randomized study was conducted on 60 adult American Society of Anesthesiologist I/II patients undergoing hip fracture fixation after obtaining institutional ethical committee clearance. Patients were randomly kept conventionally fasted before surgery (group F, n = 30) or were given oral carbohydrate 2 h before surgery (group C, n = 30). Under all aseptic precautions, a combined spinal epidural block was administered, and surgery was allowed. The primary outcome was blood glucose, and secondary outcomes included incidence of postoperative hyperglycemia, insulin level, blood urea, hunger, thirst, and anxiety. Results: Blood glucose levels were not statistically different between the two groups at baseline (T0; P=0.400), immediately after surgery (T1; P=0.399) and 24h after surgery (T2; P=0.619). The incidence of postoperative hyperglycemia was significantly higher in group F than in group C (P=0.045) at T2. Insulin levels, blood urea levels, and hunger scores were also not statistically different between the groups. The thirst and anxiety scores were lower at T0 and T1 in group C. Conclusion: Preoperative oral carbohydrate administration does not prevent perioperative increases in blood glucose levels. However, it reduces the incidence of perioperative hyperglycemia and decreases perioperative thirst and anxiety, thereby improving the quality of perioperative patient care.

Drug Resistance in Osteoarticular Tuberculosis: A Study From an Endemic Zone.

BACKGROUND: The present study was undertaken to determine the incidence of drug resistance against anti-tubercular drugs among patients from an endemic zone.  Methodology: Forty consecutive clinico-radiologically diagnosed patients of osteoarticular tuberculosis (29: spine, 11: extraspinal) were enrolled. Pus from needle aspiration was taken in 31 cases, tissue following spinal decompression in seven, synovial in one, and sinus edge biopsy in one. The pus/tissue was subjected to acid-fast bacilli (AFB) staining and liquid culture, sensitivity to 13 anti-tubercular drugs (Isoniazid (INH), rifampicin (RIF), kanamycin (KAN), amikacin (AMK,) capreomycin (CAP), ethionamide (ETH), levofloxacin (LEV), moxifloxacin (MOX), linezolid (LNZ), para-amino-salicylic acid (PAS), bedaquiline (BDQ), delamanid (DLM), and clofazimine (CFO)) were checked, and histopathological/cytopathological examination and molecular tests were performed.   Results: The mean age of patients was 29.07(9-65) years; 21 were female and 19 were male. The diagnostic accuracy for tuberculosis was 20% by AFB smear, 65% by liquid culture, 82.5% by histopathology, and 90% by cartridge-based nucleic acid amplification testing (CBNAAT). All culture-positive isolates were identified as Mycobacterium tuberculosis with no non-tubercular Mycobacterium. The drug resistance detected on CBNAAT was 11.1%, line probe assay (LPA) first line was 15.4%, LPA second line was 4%, and liquid drug susceptibility testing (DST) 11.5%. We detected 15.4% INH resistance, 11.1% RIF, 7.6% LEV, 3.8% MOX and PAS. No resistance was detected against second-line injectable drugs (SLID), ETH, LNZ, BDQ, DLM, and CFO.    Conclusions: No single laboratory modality can ascertain the diagnosis in all cases; hence, samples should be sent for all tests in tandem. In the presence of insufficient samples, tissue may be subjected to CBNAAT and histopathology to arrive at tissue diagnosis. In this subset, overall drug resistance incidence was 12.5% (5/40) with one patient each of isolated INH and RIF resistance, one of multidrug-resistance (MDR), and two of pre-extensively drug-resistant (pre-XDR). Primary drug resistance came out to be 11.1% (4/36) with one patient each of isolated INH and RIF resistance, one of MDR, and one Pre-XDR.

Effect of COVID-19 on the Burden and Profile of Orthopaedic Patients Admitted Post-Resumption of Routine Services in a Tertiary Care Hospital in Delhi.

Purpose On resumption of routine services post-lockdown during coronavirus disease 2019 (COVID-19), we expected a backlog of orthopaedic patients who could not get appropriate and timely care and would now present with complications due to missed or delayed treatment. This study aimed to quantify the effect of COVID-19 on the burden and profile of orthopaedic patients admitted post-resumption of routine services. Materials and methods Data on all the patients admitted to the orthopaedic department were collected using an interviewer-administered schedule for a complete one-year period after the resumption of routine orthopaedic services in a tertiary care hospital in Delhi. For comparison of the burden of trauma patients with that during the pre-COVID-19 period, data were obtained from a similar study done on trauma patients in 2017 at the same institution. For patients with non-traumatic conditions, previous hospital records were used. Results A total of 1585 patients were admitted during the one-year period post-resumption of routine services following COVID-19 restrictions, which was 41% less than that compared to the corresponding pre-COVID-19 data. The proportion of patients from other neighbouring states showed a decline from 52% in the pre-COVID-19 period to 41.55% when healthcare services resumed during the COVID-19 period. Out of all admitted trauma patients in 2021, 12.7% presented with a missed or complication of treatment as compared to 3.1% in the pre-COVID period. Around half of them (52.5%) attributed their complications to a COVID-19-related lockdown. Conclusion There was a significant decline in the number of patients post-resumption of routine orthopaedic care services. Converting whole tertiary care teaching hospitals to COVID-19-dedicated hospitals must not be done as it leads to an increase in missed or complication of orthopaedic treatment.

Wound Assessment Using Bates Jensen Wound Assessment Tool in Acute Musculoskeletal Injury Following Low-Cost Wall-Mounted Negative-Pressure Wound Therapy Application.

Background: Negative-pressure wound therapy (NPWT) is an alternative method of wound management for spontaneous healing. However, availability and high cost of a conventional NPWT system remain a challenge. Bates Jensen wound assessment tool (BWAT) has been used to assess wound healing in diverse wound treatments. Although there have been studies evaluating change in BWAT score following application of commercially available NPWT device, there is no literature evaluating change in BWAT score following use of wall-mounted low-cost NPWT device. Materials and Methods: Twenty patients above the age of 18 years with acute musculoskeletal wounds who underwent surgical debridement and required subsequent wound coverage were included in the study. Wound dressings were carried out using low-cost wall-mounted negative-pressure device utilizing a constant pressure of 125 mmHg for 48 h. Wound scoring was done using the Bates Jensen wound assessment tool (BWAT). The wound scores before and after application of NPWT were compared and analyzed using Wilcoxon signed-rank test. Results: Twenty patients fulfilling the inclusion criteria with a mean age of 37.10 ± 14.37 were included in the study. The average BWAT score before and after NPWT application was 31.2 ± 4.63 and 27.8 ± 3.68, respectively. The mean reduction in total BWAT score following NPWT application was 3.4. The granulation profile improved in 90% (n = 18/20) cases with a mean reduction of 1.5 ± 0.4 in the granulation tissue score. Exudation decreased in 60% (n = 12/20) patients with a mean reduction of 0.5 ± 0.23 in exudation type score and 0.35 ± 0.13 in exudation amount score. The necrotic tissue domain improved in 45% (n = 9/20) of the cases with a mean reduction of 0.45 ± 0.31 in necrotic tissue type score and 0.20 ± 0.12 in necrotic tissue amount score. Conclusion: There was a statistically significant reduction in the total BWAT score (p = 0.001) and an increase in granulation tissue (p = 0.001). The decrease in wound exudation (p = 0.004) and necrotic tissue coverage of the wound (p = 0.007) was also significant. However, there was no statistically significant change in wound depth, size, edges, undermining, tissue edema, tissue induration, and wound epithelialization after 48 h of continuous low-cost wall-mounted negative suction application in these patients.

Assessment of inter and intra-observer variation of Leonetti and Tigani CT bases classification of tibial pilon fractures.

INTRODUCTION: tibial pilon fracture constitutes 5-7% of all tibial fractures. The treatment of choice is an open reduction with anatomical articular reconstruction and stable fixation. A relievable fracture classification is needed for the preoperative planning the surgical management of these fractures. Hence, we assessed the inter- and intra-observer variation of Leonetti and Tigani CT bases classification of tibial pilon fractures. MATERIALS AND METHODS: In this prospective study, 37 patients aged between 18-65 years with an ankle fracture were included. All these patients underwent a CT scan for the ankle fracture, and the CT scan was further evaluated by 5 independent observers (Orthopaedic surgeon). A kappa value was determined for inter and intra-observer variation. RESULTS: Leonetti and Tigani's CT-based classification of the kappa values was 0.657 to 0.751, with a mean value of 0.700. The range of values for the intra-observer variation using Leonetti and Tigani CT-based classification on the kappa values was 0.658 to 0.875 with a mean value of 0.755. The P-value < 0.001 states that there was a significant agreement between the inter-observer and intra-observer classification. CONCLUSION: Leonetti and Tigani Classification have shown substantial inter- and intra-observer agreement, and the "4B" subclass of Leonetti and Tigani CT-based classification showed a predominance in the present study.

Comparison between reliability of Schatzker's classification and CT based four quadrant classification for tibial plateau fractures.

Introduction: Conventionally used Schatzker and AO/OTA classification, do not identify posterior column injuries in tibial plateau fractures. CT based Four quadrant classification, has been proposed to identify fractures of tibial plateau and help in surgical planning of treatment. However, to assess its validity, there is scanty literature about its reliability (inter and intra-observer variation) and comparison of its reliability with that of the more popular Schatzker classification in classifying tibial plateau fracture. Material and methods: X-rays and CT scans of 35 patients (18-65 years) of closed tibial plateau fractures were assessed by 5 Orthopaedic surgeons and classified by both Schatzker's and Four Quadrant Classification. A similar observation was recorded after 2 months. All observers were blinded for the demographic and clinical details of the patients. Their responses were noted and interobserver and Intraobserver variation was calculated. Kappa Test of Cohen was used to determine the level of agreement, as per Landis and Koch's criteria. The reliability of four quadrant classification was also compared with that of Schatzker's classification. Results: There was a moderate agreement in interobserver variation in observations for Schatzker's classification (on X-rays) which improved to substantial agreement when the observations were recorded after showing both CT and X-rays. The intraobserver variation had substantial agreement. On the other hand, there was a perfect agreement in both intra- and interobserver variation for Four Quadrant Classification. This difference between the reliability of both classifications was statistically significant (p < 0.001). Conclusions: Four Quadrant classification is a more reliable classification having a better agreement on interobserver and intraobserver variation.

Efficacy of Single Injection of Platelet-Rich Plasma in Shoulder Impingement Syndrome.

Introduction To analyze the change in Visual Analog Scale (VAS), QuickDASH score, and the range of motion at the shoulder joint following a single injection of platelet-rich plasma (PRP) in shoulder impingement syndrome. Methods Twenty patients (21 shoulders) of either sex above the age of 18 years with a clinical diagnosis of shoulder impingement having a positive shoulder impingement test (positive Hawkins-Kennedy impingement test and/or positive Neer's impingement sign), ultrasonographic confirmation of shoulder impingement, and a failure to respond to standard non-operative methods for a minimum period of four weeks were included in this prospective interventional study. PRP was injected at the proposed site. At three months after the injection, the changes in the VAS, QuickDASH score, and the range of motion at the shoulder joint were analyzed. Results There were significant changes in the VAS, QuickDASH score, and range of motion at the shoulder joint following a single injection of PRP. Conclusions Platelet-rich plasma (PRP) injection results in a significant decrease in pain and improvement in the range of motion and an overall excellent functional outcome in shoulder impingement syndrome. However, future studies with a bigger sample size and longer follow-up are needed.

Outcomes of Displaced, Comminuted, Intracapsular Neck Femur Fracture in Young Adults Managed with Three Screw Inverted Triangle Versus Four Screw Diamond Configuration: A Comparative Pilot Study.

Background: Three cannulated cancellous screws (CCS) inverted triangle configuration is considered to be the gold standard for management of displaced intracapsular neck femur (ICNF) fractures in young adults. However, some authors have recommended four CCS in diamond configuration in the presence of comminution. However, there are no comparative studies to assess the superiority of one over the other. Therefore, the aim of the present study was to compare the radiological and functional outcomes of displaced, comminuted, ICNF fracture in young adults managed with three screw inverted triangle versus four screw diamond configuration CCS fixation. Material and Methods: Twenty-three patients (group I) with displaced comminuted ICNF fractures were managed with three CCS fixation in inverted triangle fashion between October 2014 and October 2015 and were followed up for a mean duration of 33.5 months (range 25-38 months). Twenty-five patients (group II) with the same inclusion and exclusion criteria were managed with four CCS in diamond configuration between October 2013 and October 2014 and followed up for a mean duration of 33.3 months (range 25-38 months). Radiological outcomes of these patients were compared in terms of union rates and avascular necrosis, while functional outcome was measured by Harris Hip Score (HHS) at a minimum of 24 months. Results: Nineteen patients of group I and 20 patients of group II were available for final follow-up. Mean union time in group I was 15 weeks (12-24 weeks), while in group II, it was 14 weeks (12-24 weeks). There was total of four (4/19) cases of non-union in group I, while it was two (2/20) cases in group II. One patient (1/19) developed avascular necrosis in group I, while two (2/20) developed the same in group II. In group I, the mean HHS was 87.3 (range 84-94) points, while in group II, mean HHS was 93.5 (range 78-96) points. Conclusion: There is no difference in the clinical and radiological outcomes following three screw inverted triangle or four screw diamond configuration CCS fixation of displaced comminuted ICNF fracture in young adults. Thus, we conclude that both three screw inverted triangle or four screw diamond configuration CCS fixation are effective treatment modalities for fracture neck femur with comminution and in the absence of larger studies and long-term follow-up the superiority of one over the other cannot be recommended.

Study of Cell Viability and Etiology of Contamination in Decalcified Bone Allograft: A Pilot Study.

BACKGROUND: Bone allografts can elicit immune responses which is correlated with the presence of Human Leukocyte Antigen (HLA) and cellular DNA. It also has risk of causing occult infection arising out of contamination during its processing and storage. The presence of immunogenic materials like cells, cellular remnants and DNA in a decalcified bone allograft during different phases of processing has never been studied. Present study was conducted to explore- the cell viability using routine Hematoxylin and Eosin, presence of DNA using Feulgen staining and etiology of contamination in decalcified bone allograft during procurement, demineralization and ethanol preservation. METHODS: The harvested bones from patients undergoing hemireplacement/THR/TKR were processed to prepare decalcified bone allografts. The samples during procurement (A), HCL treatment (B) and ethanol preservation (C) were sent for histopathological analysis (number of osteocytes in the maximum density field under 40x and the cells demonstrating presence of DNA on feulgen stain) and microbiological assessment (aerobic/anaerobic/fungal cultures). RESULTS: Histopathological study demonstrated the presence of osteocytes and other cells like bone marrow, adipocytes, endothelial cells in the decal bone allograft. The average number of osteocytes gradually decreased from 55.47, 9.6, 0.86 in sample A, B, C, respectively. Feulgen staining confirmed the presence of DNA in osteocytes and other cells which decreased both qualitatively and quantitatively in subsequent stages of processing. Rate of contamination demonstrated at the procurement was 6.67% (Staphylococcus aureus). After treatment with HCl (demineralisation), 7.14% of non-contaminated allografts were found contaminated (Staphylococcus epidermidis). None of the remaining 13 non-contaminated allografts showed contamination after storage in ethanol. Overall 13% of the patients had positive cultures on microbiological assessment. CONCLUSION: The population of osteocytes in the harvested bone reduced significantly after processing with HCl and ethanol preservation. Presence of DNA, demonstrated by using Feulgen staining, was observed in bone marrow cells, adipocytes along with osteocytes which showed quantitative reduction on processing. Hence, antigenicity, conferred by cells and their DNA, reduced significantly after processing of decal bone. Contamination rate of banked decalcified allograft was 13%. Thus, culture and sensitivity tests should be carried out at each step of processing of decal bone allograft.

Change in granulation tissue coverage and bacteriological load using Low Cost Negative Pressure Wound Therapy in acute musculoskeletal wounds.

BACKGROUND: Low cost Negative Pressure Wound Therapy (NPWT) dressings have been considered as an alternative to traditional daily dressings. There is scanty literature evaluating the change in the percentage area of wound covered by granulation tissue following application of low-cost NPWT. The change in the bacteriological flora following application of low-cost NPWT devices has also not been evaluated. METHODS: Patients above the age of 18 years with acute musculoskeletal injuries of <3 weeks duration which underwent a surgical debridement and required subsequent wound coverage were included in the study. Area of the wound and the area covered by the granulation tissue as well as the bacteriological count were measured before and after application of NPWT. A low cost NPWT using wall mounted vacuum device was put on the patient giving a constant negative pressure of 125 mm of Hg for 2 days. The findings before and after application of NPWT were compared and analyzed using Wilcoxin Signed-rank test. RESULTS: 21 patients with mean age of 35.52±15.075 were included. The pre-NPWT granulation tissue area ranged from 122 mm2 to 8483 mm2 with a mean of 1648.38 mm2 (SD = 1933.866). The post-NPWT granulation tissue area ranged from 234 mm2 to 7847 mm2 with a mean of 2364.48 mm2 (SD = 1857.716). The mean increase in granulation tissue was 716.1 mm2.The pre-NPWT wound area ranged from 422 mm2 to 10847 mm2 with a mean of 4009.62 mm2 (SD = 3026.209). The post-NPWT wound area ranged from 326 mm2 to 9143 mm2 with a mean of 3410.33 mm2 (SD = 2636.206). The mean reduction in wound size was 599.29 mm2.The pre-NPWT bacteriological count ranged from 3000/ml to 130000000/ml with a mean of 12616761.90/ml (SD = 29664589.37). The post-NPWT bacteriological count ranged from 1000/ml to 380000000/ml with a mean of 26401523.81/ml. The mean increase in bacteriological count was 13784761.91/ml. CONCLUSION: There was a statistically significant decrease in wound size (p = 0.001) and statistically significant increase in percentage area of granulation tissue coverage (p = 0.000) following low cost NPWT application. However there was no statistically significant increase in bacteriological clearance in these patients.

Outcome of Dome Osteotomy With Plate Osteosynthesis for Genu Valgum in Late Adolescents and Young Adults.

Aim To evaluate the degree of correction and outcomes after correction of genu valgum deformity using dome osteotomy with plate osteosynthesis in late adolescents and young adults. Methods A total of 27 knees in 21 patients underwent correction using dome osteotomy fixed with 3.5-mm low-profile proximal humeral locking system (PHILOS) plate. The functional, clinical, and radiological assessments were performed preoperatively and at six months postoperatively. Functional assessment was performed using the Bostman score, while clinical and radiological assessments were performed by measuring intermalleolar distance, tibiofemoral angle, mechanical lateral distal femoral angle, and mechanical axis deviation. All values were compared preoperatively and postoperatively using the paired t-test and Wilcoxon's test. Results The comparison between preoperative and postoperative data was statistically significant (P<0.0001). Twenty patients had an excellent knee score, and one patient had a good score. None had an unsatisfactory score. Conclusions Dome osteotomy fixed with well-contoured, 3.5-mm low-profile PHILOS plate allows deformity correction at the CORA (center of rotation of angulation) of the knee and permits early knee mobilization without significant procedure or implant-related complications with excellent outcomes.

Four Screws Diamond Configuration Fixation for Displaced, Comminuted Intracapsular Fracture Neck Femur in Young Adults.

BACKGROUND: Four cannulated cancellous screws (CCS) in diamond configuration have been recommended by some authors for fixation of intracapsular neck of femur (ICNF) fracture with posterior comminution in adults. This is also supported by biomechanical studies. However, the clinical usefulness of this biomechanical advantage is not known. This study evaluates the outcomes of displaced, comminuted ICNF fracture in young adults managed by four CCS fixation in diamond configuration. MATERIALS AND METHODS: 25 patients who met the inclusion criteria were operated during the study period. Four patients were lost to followup in the first 6 weeks postoperatively, and one patient died in first 6 months of followup unrelated to surgery. Thus, twenty patients were followed up for a mean period of 33.3 months (range 25-38 months). In all patients, fracture fixation was done with four CCS in diamond configuration. Union at fracture site and avascular necrosis (AVN) of femoral head was assessed on serial plain radiographs. Functional outcome was evaluated by Harris hip score. RESULTS: Eighteen patients had union, two patients had nonunion, and two patients had AVN of femoral head. All the sixteen patients who had union without AVN had good or excellent functional outcome. CONCLUSIONS: The present study concludes that four CCS fixation in diamond configuration appears to be a reasonable choice of fixation for displaced fracture ICNF with comminution in young adults. However, further evaluation with better study design and larger patient population is required for definite conclusions.

Exposed versus Buried Kirschner Wires Used in Displaced Pediatric Fractures of Lateral Condyle of Humerus.

BACKGROUND: Comparision of results and complications of exposed versus buried Kirschner wires (K-wires) after open reduction of lateral condyle fractures is scarce and mainly from western population; hence, we envisaged to study the safety and efficacy of exposed and buried K-wires used for fixation of displaced pediatric fracture of the lateral condyle of humerus in Indian setup. MATERIALS AND METHODS: A prospective, nonrandomized, comparative study was conducted in 50 patients with age <12 years, presenting with displaced fracture of lateral condyle of humerus of <2 weeks duration, without associated ipsilateral upper limb injury, who were treated by open reduction and internal fixation with either exposed or buried K-wires (n = 25 in each group). At a minimum followup of 3 months, status of fracture reduction, union, evidence of osteomyelitis, carrying angle at the elbow, and elbow range of motion (ROM) were assessed clinicoradiologically. RESULTS: Four (16%) patients in exposed group and 1 (4%) in buried group had superficial infection, while 3 (12%) patients in exposed group and 2 (8%) in buried group had deep infection. All the patients with infection responded well to oral antibiotics and regular dressings. Buried group had higher incidence of secondary skin and wire-related complications. CONCLUSION: There was no statistical difference between the two groups but exposed K wires are easy to remove so are preferred over buried K wires.

Femoral fracture acting as an "ominous masquerade" in a 7-year-old child.

A pathological fracture is one which occurs in diseased bone with trivial trauma or even without it. However, fracture occurring as a result of significant injury can masquerade underlying ominous bone pathology, which is highly likely to be missed in the garb of overwhelming traumatic aetiology. Pathological fracture as the manifestation of tumour in children less than 10 years of age is rare.1, 2 Fracture following significant trauma masquerading as underlying malignancy is even rarer. We report a case of 7-year-old male child, he had history of significant trauma with fracture shaft of femur, pathology was "missed" initially in the outset of trauma and on subsequent follow up it was found to be osteosarcoma.

Assessment of the geometry of proximal femur for short cephalomedullary nail placement: An observational study in dry femora and living subjects.

BACKGROUND: Intramedullary devices have increasingly become popular and are widely used for fixation of unstable intertrochanteric and subtrochanteric fractures. These implants have been designed taking into consideration of the anthropometry of the western population which varies from those of other ethnic groups. This study was carried out to assess the geometry of proximal femur for the placement of short cephalomedullary nails in our subset of patients and suggest suitable design modifications based on these parameters. MATERIALS AND METHODS: The study was conducted in the following three groups: (1) Anthropometric study of 101 adult human dry femora, (2) radiographs of the same femora, and (3) radiographs of the contralateral uninjured limb of 102 patients with intertrochanteric or subtrochanteric fractures. In Group 1, standard anthropometric techniques were used to measure neck shaft angle (NSA), minimal neck width (NW), trochanteric offset, and distance from the tip of greater trochanter (GT) to the lower border of lesser trochanter on the femoral shaft axis (distance X). In Group 2 and 3, the NSA, minimal NW, NW at 130° and 135°, trochanteric shaft angle (TSA), trochanteric offset, distance X, distance between the tip of GT and the point where the neck axis crosses the line joining the tip of the GT to the lower border of the lesser trochanter on the femoral shaft axis (distance Y), and canal width at 10, 15, and 20 cm from tip of GT were measured on standard radiographs. The values obtained in these three groups were pooled to obtain mean values. Various parameters of commonly used short cephalomedullary nails available for fixation of pertrochanteric fractures were obtained. These were compared to the results obtained to suggest suitable modifications in the nail designs for our subset of patients. RESULTS: The mean parameters observed were as follows: NSA 128.07° ± 4.97 (range 107°-141°), minimum NW 29.0 ± 2.8 mm (range 22-42 mm), NW at 130° 30.12 ± 2.86 mm (range 22.2-42.5 mm), NW at 135° 30.66 ± 3.02 mm (range 22.8-40.3 mm), TSA 10.45° ± 2.34° (range 3°-15.5°), distance X 65.73 ± 6.45 mm (range 28.6-88.4 mm), distance Y 38 ± 4.91 mm (range 16.6-55.3 mm), and canal width at 10, 15, and 20 cm from the tip of GT 13.46 ± 2.34 mm, 11.40 ± 2.27 mm, and 11.64 ± 2.04 mm, respectively. CONCLUSION: The measurements of the proximal femur are not significantly different from other ethnic groups and are adequate to accept the current commonly available short cephalomedullary nails. However, certain modifications in the presently available short cephalomedullary nail designs are recommended for them to better fit the anatomy of our subset of population (a) two nails of 125° and 135°, (b) the medio-lateral angle at the level of 65 mm from the tip of the nail, (c) two femoral neck screw placements (35 and 45 mm from the tip of the nail), and (d) five different sizes of distal width for better fit in canal (9-13 mm).

Bone and Joint Infections in Children: Septic Arthritis.

The pathological invasion of a joint and subsequent inflammation is known as septic arthritis. The knee and hip are the most frequently involved joints. Staphylococcus aureus is the most common cause of septic arthritis in children. An acute onset of illness with an inflamed painful joint and restricted movements and inability to use joint (pseudoparalysis) clinically indicates septic arthritis. The diagnosis is difficult in a neonate or young child where refusal to feed, crying, discomfort during change of diaper (if hip is involved) or attempted joint movement may be the only findings. Fever and other systemic signs may also be absent in neonates. Septic arthritis is diagnosed clinically, supported by appropriate radiological and laboratory investigations. The peripheral blood white cell count is frequently raised with a predominance of polymorphonuclear cells. The acute phase reactants such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are often markedly raised. Ultrasonography and MRI are preferred investigations in pediatric septic arthritis. Determination of infecting organism in septic arthritis is the key to the correct antibiotic choice, treatment duration and overall management. Joint aspirate and/or blood culture should be obtained before starting antibiotic treatment. Several effective antibiotic regimes are available for managing septic arthritis in children. Presence of large collections, thick pus, joint loculations and pus evacuating into surrounding soft tissues are main indications for surgical drainage. Joint aspiration can be a practical alternative in case the lesion is diagnosed early, with uncomplicated presentations and superficial joints.

Bone and Joint Infections in Children: Acute Hematogenous Osteomyelitis.

Acute hematogenous osteomyelitis (AHO) is one of the commonest bone infection in childhood. Staphylococcus aureus is the commonest organism causing AHO. With use of advanced diagnostic methods, fastidious Kingella kingae is increasingly becoming an important organism in etiology of osteoarticular infections in children under the age of 3 y. The diagnosis of AHO is primarily clinical. The main clinical symptom and sign in AHO is pain and tenderness over the affected bone especially in the metaphyseal region. However, in a neonate the clinical presentation may be subtle and misleading. Laboratory and radiological investigations supplement the clinical findings. The acute phase reactants such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are frequently elevated. Ultrasonography and MRI are key imaging modalities for early detection of AHO. Determination of infecting organism in AHO is the key to the correct antibiotic choice, treatment duration and overall management and therefore, organism isolation using blood cultures and site aspiration should be attempted. Several effective antibiotics regimes are available for managing AHO in children. The choice of antibiotic and its duration and mode of delivery requires individualization depending upon severity of infection, causative organism, regional sensitivity patterns, time elapsed between onset of symptoms and child's presentation and the clinical and laboratory response to the treatment. If pus has been evidenced in the soft tissues or bone region, surgical decompression of abscess is mandatory.

Outcome of low level lasers versus ultrasonic therapy in de Quervain's tenosynovitis.

BACKGROUND: de Quervain's tenosynovitis is an inflammation of abductor pollicis longus (APL) and extensor pollicis brevis (EPB) muscle tendon sheaths at the level of radial styloid process. Its conservative management includes nonsteroidal anti-inflammatory drugs, wrist and thumb immobilization, ultrasonic therapy (US Th.) and low level laser therapy (LLLT). Literature is scanty on comparative efficacy of US Th. and LLLT for its management. This prospective study evaluates outcome of US Th. versus LLLT in de Quervain's disease. MATERIALS AND METHODS: Thirty patients clinically diagnosed de Quervains tenosynovitis were included in the study and randomly assigned to two groups. The average age was 36 years (range: 21-45 years). One group was given LLLT and the other US Th. for a total of 7 exposures on alternate days. The clinical criteria used were Finkelstein's test, tenderness over radial styloid (Ritchie's tenderness scale), grip strength, pain (visual analog scale [VAS]) and radiological criteria was ultrasonographic assessment of change in thickness of APL and EPB tendon sheath. They were measured before commencement and at the end of seven sessions of therapy, as per standard procedure. RESULTS: Significant improvement was seen within both groups in the following outcome measures assessed: Ritchie's tenderness scale, grip strength and VAS. Finkelstein's test was not significantly improved in either groups. Ultrasonographic measurement of tendon sheath diameters, the mediolateral (ML), and anteroposterior (AP) diameters was not found to be significantly different in the US Th. group and the laser therapy group after treatment. On comparing both the groups, no statistically significant difference was found. However, looking at the mean values, the grip strength and VAS showed better improvement in the US Th. group as compared to the laser therapy group.

Augmentation of bone healing in delayed and atrophic nonunion of fractures of long bones by partially decalcified bone allograft (decal bone).

BACKGROUND: Autograft from iliac crest is considered as gold standard for augmentation of bone healing in delayed and nonunion of fractures. Bone demineralized with 0.6N hydrochloric acid has shown to retain its osteoinductive capacity. We report the outcome of partially decalcified bone allograft (decal bone) in the treatment of delayed union and atrophic nonunions of bones. MATERIALS AND METHODS: Twenty patients with clinicoradiological diagnosis of delayed union or atrophic nonunion of long bone fractures were included in this retrospective study. Patients at extreme of ages (<18 years and >60 years), pathological fractures, metabolic bone diseases, infected nonunion, hypertrophic nonunion and those having systemic illness like diabetes mellitus and on drugs that impair fracture healing were excluded from the study. Decal bone was prepared in the bone bank and maintained in department of orthopedics. Allografting was done in 20 patients of delayed union (9/20) and atrophic nonunion (11/20) of long bone fractures with mean age of 34 years (range 18-55 years). The bones involved were humerus (8/20), tibia (7/20) and femur (5/20). Fourteen patients underwent treatment in the form of internal fixation and allografting and six patients were operated with osteoperiosteal allografting. RESULTS: Nineteen patients achieved union in mean time of 14.9 weeks range (range 8-20 weeks). Eight patients had serous discharge from the operative site that subsided in 11 days (range 4-21 days). One patient had pus discharge that required repeat debridement and antibiotics for 6 weeks. The fracture healed in 16 weeks. CONCLUSION: The partially decalcified bone allograft is an effective modality for augmentation of bone healing without complication associated with autograft like donor site morbidity, increased blood loss and increase in the surgical time.

Malunion in displaced intracapsular fracture of femoral neck: A rare case.

Intracapsular fracture of femoral neck is treated by anatomical reduction (preferably closed) and cannulated cancellous lag screw fixation. Malunion of these fractures have been described in the coronal plane (coxa valga or coxa vara). We reported a case of young adult patient with displaced intracapsular fracture of femoral neck that had malunited in sagittal plane with callus formation with excellent functional outcome. The radiographs revealed intracapsular fracture of femoral neck right side (Garden type 4 and Pauwel type 3). The patient was operated and closed reduction and internal fixation with three cannulated cancellous screws was performed. The postoperative radiograph revealed a loss of reduction in the lateral view. Due to this technical error, the patient was counselled for revision fixation for which he refused. At 9 months we observed union of the fracture in the displaced position by callus formation. Harris hip score at 2 years was 96 that indicate excellent functional outcome and the radiographs did not reveal any evidence of avascular necrosis of femoral head. We advised revision surgery to our patient as he had increased chances of implant failure and nonunion. However he refused the revision surgery and was continued with the suboptimal reduction. However, the fracture united and that too with callus formation, which is not a described phenomenon in neck of femur fracture.
