Pre-operative fixed flexion deformity a curse to the knee arthroplasty surgeon?
Background: The aim of the study was to study the effect of preoperative flexion deformity on the postoperative knee range of motion following total knee arthroplasty.Methods: A total of 28 knees were studied out of which twenty were osteoarthritis and eight were rheumatoid arthritis. Cruciate substituting and cruciate retaining implants were used. Patients above the age of 45 years with a minimum follow up period of two years from April 2010 were studied.Results: 28 knees had an average preoperative range of motion of 87.678. Patients with preoperative flexion deformity had postoperative range of motion of 97.5 degrees. The average postoperative flexion in 8 rheumatoid patients was 96.25 and 20 osteoarthritis patients was 107.462.Conclusions: The average postoperative range of motion was 105.538. Patients with a higher pre-operative range of motion had higher postoperative range of motion. Rheumatoid patients had a significantly low range of motion when compared to osteoarthritis patients. Patients with increased fixed flexion deformity had a significantly low postoperative range of motion

Efficacy and safety of two different doses of intrathecal calcitonin, a randomized controlled study
Background: Adjuvants play an important role in enhancing the quality of anesthesia and also in reducing the requirement of primary anesthetic and its related adverse events. Calcitonin is one such adjuvant. But there is still uncertainty regarding the appropriate dose of calcitonin to achieve maximum analgesic efficacy and safety. The current study is conducted to add to the existing evidence on the subject and was aimed to compare the efficacy and safety of two different doses of calcitonin as an adjuvant in patients undergoing spinal anesthesia.Methods: A prospective randomized controlled double-blind trial was conducted in the Department of Anesthesiology and Intensive Care, Sir Sunderlal Hospital, Banaras Hindu University from May 2006 to May 2007. A total of 80 participants aged between 18 to 60 years, with ASA I and II physical status, undergoing infra-umbilical surgeries were randomly allocated to one of the 4 intervention groups. All the 4 intervention groups received 0.5% bupivacaine (H) 3ml as a primary anesthetic agent. Group I and III received 50 IU and 100 IU salmon calcitonin as an adjuvant. Group II received placebo and group IV (control) received no adjuvant. Pinprick test, Bromage scale and 10-point Visual analog scale (VAS) were used to measure the efficacy.Results: All the study groups were comparable with respect to all baseline variables. The time interval to the first dose of analgesia was longest in 100 I.U. calcitonin group, followed by 50 I.U. calcitonin group, placebo control group. The mean duration of analgesia (in minutes) among group I (100I.U. calcitonin) was 230.00±92.39, 159.25±21.59 among group II (Placebo), 161.50±31.20 among group III (50 I.U. calcitonin) and 142.75±20.22 among group IV. Considering group IV (control group) as base line. The differences of duration of analgesia (in minutes) in group I, group II and group III with baseline value (group IV) were statistically significant (P value <0.05). Even though the proportion of subjects developing adverse events was slightly higher in 100 I.U calcitonin groups compared to other groups, they were minor adverse events and were managed appropriately. There were no significant differences across the study groups in terms of hemodynamic stability.Conclusions: Salmon calcitonin as adjuvant increases the duration of postoperative analgesia. Even though the there slightly higher incidence of adverse events with 100 I.U calcitonin they are minor and the risk-benefit ratio favors calcitonin use. To make a categorical recommendation on the appropriate dose, there is further need for large-scale studies and pooled analysis
Functional and radiological outcomes of distal humerus fractures treated with pre-contoured locking compression plate
Background: Distal humerus intra-articular fractures are one of the complicated fractures managed by orthopaedic surgeons. We did a prospective and a retrospective study on 21 patients with these fractures treated with pre-contoured locking compression plate.Methods: The 21 patients in this series were followed for a minimum of 1 year. The prospective study cases were followed at 3 months, 6 months and annually. The rating system of the Mayo elbow functional scoring system was used. The radiological evaluation was done using standard AP and lateral views.Results: We had 14 patients with range of motion of 50-100 degrees. There was only one patient with range of motion of <50 degrees. 6 patients had the maximum range motion of >100 degrees. We had 6 (23.57%) excellent, 9 (42.85%) good, 5 (23.80%) fair and 1 (4.7%) poor in the Mayo elbow scoring at the end of 1 year. We were able to compare our outcomes with a study done by Kumar et al done in 2017. They had 27 (89.66%) of excellent and good results as opposed to 27 (79.4%) in our study. Out of 21 patients in our study 17(80.95%) patients had good 11 (52.5%) / excellent 6 (28.5%) results. This was comparable with Jupiter et al. His study of 34 patients 26 (79.40/0) patients showed good 14 (41%) / excellent 13 (38.4%) result.Conclusions: Pre-contoured locking compression plate appears to be technically an ideal implant for comminuted osteoporotic bone providing an angle stable construct

NOVEL HYDROXYL TERMINATED DENDRIMERS AS POTENTIAL DRUG CARRIERS: SUSTAINED RELEASE, HEMOLYSIS AND CYTOTOXICITY STUDY
Objective: Potential of novel hydroxyl terminated dendrimer generations G1(OH)8, G2(OH)32 and G3(OH)128 as solubility enhancers of model drug ketoprofen was evaluated. G3(OH)128 dendrimer was further explored as the novel carrier for sustained release of ketoprofen. Cytotoxicity and hemolytic potential of G3(OH)128 dendrimer were studied to evaluate toxicity of dendrimer.
Methods: Higuchi and Connors method was employed to evaluate improved solubility of ketoprofen at different pH and dendrimer generation. Ketoprofen was loaded into G3(OH)128 dendrimer by inclusion complex method. Ketoprofen loaded dendrimer was characterized by Flourier Transform infrared spectroscopy. Sustained release of ketoprofen from ketoprofen loaded dendrimers was studied and compared to that of free ketoprofen. Cytotoxicity of dendrimers on A-549 cell lines were studied by MTT assay technique. Hemolytic potential of G3 dendrimer was also studied.
Results: Solubility of practically insoluble ketoprofen was improved up to 0.77-4.89 mg/ml by dendrimer generations. Solubility of ketoprofen was increased with increase in pH, concentrationand generation number of dendrimer. Ketoprofen was released relatively slowly from ketoprofen loaded dendrimer compared to free ketoprofen. Cytotoxicity and hemolytic assay revealed that dendrimers were less toxic compared to PAMAM dendrimers.
Conclusion: Improved solubility of ketoprofen by dendrimer generations, its slow release from G3(OH)128 dendrimer and cytotoxicity and hemolytic assay showed dendrimers have potential as drug carriers.

Primary total knee replacement using dished polyethylene with resected posterior cruciate ligament
Background: The choice between preserving, sacrificing or substituting the posterior cruciate ligament (PCL) is always a controversial topic in total knee replacement (TKR). Dished polyethylene insert with PCL resection enables correction of the commonly present fixed flexion and varus deformities. Additionally, the risk of premature wear of polyethylene is less because of the confirming articular geometry between the femoral and tibial component.Methods: This is a retrospective study in which we studied 120 knees in 95 consecutive patients undergoing primary TKR by the senior author at our institute. We used TKR system with dished metal backed polyethylene tibial component. PCL resection was performed in all cases. Pre-operative and post-operative functional assessment were done using knee society clinical scores and Western Ontario and McMaster universities osteoarthritis index (WOMAC). All radiographs were assessed using the knee society Roentgenographic scoring system (KSRES). Statistical analysis was performed using paired student t tests. Survivorship was determined using Kaplan-Meier survivorship curves. Results: Mean follow-up was 8 years. Range of motion increased from 75 degrees to 110 degrees. The knee society pain score increased from 30 to 94. The knee society function score increased from 35 to 75. WOMAC score increased in terms of pain, stiffness and physical function.Conclusions: We conclude that deep dish bearing is a viable option in presence of deficient PCL and provides adequate stability and functional outcome. We need a larger sample size, multicentre trial and longer follow-up to see for complication rate, revision rate and survival
