Background: The management of bone gap in the femoral shaft has remained difficult and challenging to the orthopaedic and trauma Surgeons. Distraction osteogenesis using the linear rail system (LRS) may be a useful tool in bridging such defects in our environment. Objective: To study the radiologic bone union, functional outcome and complications of distraction osteogenesis in the management of femoral bone gap using linear rail system (LRS). Methodology: A hospital based prospective interventional study conducted at National Orthopaedic Hospital, Dala and Albarka clinic, Dandishe, Kano, between March 2013 and March 2018. Sixty-eight cases were recruited. Every patient had LRS applied after adequate debridement when needed. Primary or interval corticotomy was done depending on the extent of soft tissue dissection in relation to the corticotomy site. Follow up was done until the regenerate had corticalized and LRS removed. Complications were noted and recorded. Radiologic union and functional outcome were assessed using the RUST and ASAMI outcome scores respectively. Data was analyzed using SPSS version 20. Results: Sixty-eight cases were recruited with M: F ratio of 16: 1. The mean age was 36.7 +/- 10.5years. The age range between 36-45years was more commonly treated representing 34(50.0%). Primary corticotomy was done in 52 (76.5%) while interval corticotomy was done in 16 (23.5%). The mean regenerate length achieved was 9.6 +/- 2.7cm. The mean duration of treatment was 20.3 +/- 6 months. Radiologic union was achieved in 66 (97.1%) patients. Sixty-four (94.1%) had excellent or good ASAMI functional outcome scores. Sixty-six (97.1%) were either very satisfied or satisfied with their treatment while 2 (2.9%) were indifferent. The common complications were intermittent pin tract infections recorded in 28 (41.2%), knee stiffness in 18 (26.5), proximal or distal varus deformity in 10 (14.7%) and non-union in 2 (2.9%) of cases. Conclusion: Distraction osteogenesis using LRS can achieve bone union and excellent outcome in the management of bone gap in the femur. However, intermittent pin tract infection, knee stiffness and varus deformities post significant challenges.

Return To Duty

Background Scaphoid nonunion can occur in up to 55% of displaced scaphoid fractures. Long-term functional outcomes of this injury are lacking. In addition, no study has published rate of return to active military service after this injury. Our goal was to educate providers and patients on expected functional outcomes and return to duty after treatment of scaphoid nonunion. Methods We conducted a retrospective review of patients who underwent scaphoid nonunion repair at our institution from 2008 to 2017. The primary outcome measures were union rates, return to duty rates, and functional outcome scores obtained by telephone call. A total of 144 patients were included and 40 responded to our call for long-term follow-up. Results A total of 72% of patients achieved union after surgery, 18% required revision surgery, and 74% of patients were able to return to full duty after surgery. However, this number progressively decreased at 1, 2, and 5 years after surgery. At an average of 5.9 years after surgery, the mean Quick Disabilities of the Arm, Shoulder, and Hand (qDASH) score was 23.9. The mean qDASH for patients who achieved union (21.9) was significantly lower than those with persistent nonunion (29.2) ( P = .0115). Conclusion Scaphoid nonunion is a difficult problem in the military. We found a high rate of persistent nonunion often requiring revision to partial or full wrist arthrodesis. In addition, our long-term functional outcome scores demonstrate significant disability after this injury, even when union is achieved. This information can help us better counsel our patients and set expectations after treatment of this injury.

Background: Planter fasciitis, is by definition, inflammation of planter fascia. Most of the cases are well treated conservatively and a few responds to surgery only. Objectives of present study were evaluating the efficacy of a single injection of leukocyte free platelet rich plasma in plantar fasciitis and to derive a correlation between the clinical and radiological outcome.Methods: The present study consisted of 120 patients of bilateral (PF), (240 feet). These patients were divided into two groups PRP group of 60 patients and Placebo group of 60 patients. The study was conducted on patients attending Orthopaedics outpatient department Post Graduate Institute of Medial Education and Research (PGIMER) from July 2011 to June 2012. A primary efficacy criterion was changes from baseline in pain using (VAS). Functional results, level of satisfaction and outcome were measured by – AOFAS Foot Scale. Correlation of clinical with radiological outcome were performed.Results: There was a significant decrease in the visual analogue scale (pain score) in the PRP. Group while in placebo group it was increased significantly at the end of 6 month. Functional outcome scores were improved significantly from their baseline values in PRP group while in placebo group the mean functional score were deteriorated at 6 months follow up. There was no improvement seen in functional status with normal saline injection. In PRP group the mean heal pad thickness was reduced significantly at 6 months follow up while in placebo group was not changed significantly at 6 months follow up. Correlation between radiological parameters and VAS was found to be positive while it was found negative with other functional outcome scores like AOFAS.Conclusions: Platelet-rich plasma (PRP), which is a natural concentrate of autologous growth factors,plays a role in the regeneration process in treatment of (PF).

Abstract Background The natural history of scaphoid nonunion is the development of degenerative arthritis. A lot of information is still unclear about this progression. The purpose of this study is to analyze patients with scaphoid nonunions who had not received any kind of treatment and to assess the functional outcome. Materials and Methods This is a retrospective study that analyzed the patients with chronic scaphoid nonunions between 2009 and 2019. None of the patients received any treatment. The age at the time of injury, examination, pattern of fracture, types of scaphoid nonunion, symptoms, and duration of nonunion were noted. Diagnosis was confirmed by radiographs, computed tomography (CT) scan, and magnetic resonance imaging (MRI). Scapholunate and radiolunate angles were recorded. Pain score, modified mayo wrist score, grip strength, range of movement, and the functional outcome of these scaphoid nonunions were analyzed. A statistical correlation between the scaphoid nonunion presentations and the functional outcome was assessed. Results The mean age of the patients was 62 years (range: 35–82 years.). There were 17 male and 3 female patients. There were 9 waist and 11 proximal pole scaphoid nonunions. The mean duration of scaphoid nonunion was 34 years (range: 10–62 years). None of the patients had avascular necrosis (AVN) of the proximal scaphoid. The age at examination, gender, side of injury, fracture pattern (waist/proximal pole), fracture displacement ≤ 1 mm or > 1 mm, nonunion duration, and radiographic arthritic parameters had no significant impact on the functional outcome. Conclusions Untreated chronic scaphoid nonunion leads to the development of degenerative arthritis over a period of years, which is still unpredictable. Most of the patients become aware of the nonunion following a precedent injury or other reasons. Most of the patients have fair/good functional outcome despite reduced range of movements and grip strength. Many do not favor surgical intervention in the course of nonunion. Chronic nonunions open a lot of unanswered questions. Clinical relevance There have been numerous studies on the treatment aspects of scaphoid nonunion, with little knowledge about certain people with nonunion who did not have any kind of treatment. The demographics, clinical findings, and radiological parameters do confirm the progression of these nonunion to arthritis, but most of them had fair-to-good outcome throughout their life. It opens our thinking about the real need of treatment in such nonunions and raises numerous questions about the disease. Level of evidence This is a Level IV study.

AbstractPatello-femoral arthroplasty (PFA) is successful in a selected group of patients and yields a good functional outcome. Robotic-assisted knee arthroplasty has been shown to provide better implant positioning and alignment. We aim to report our early outcomes and to compare Mako's (Robotic Arm Interactive Orthopaedic System [RIO]) preoperative implant planning position to our intraoperative PFA implant position. Data for this study was prospectively collected for 23 (two bilateral) patients who underwent robotic-assisted PFA between April 2017 and May 2018. All preoperative implant position planning and postoperative actual implant position were recorded. Presence of trochlear dysplasia and functional outcome scores were also collected. There were 17 (two bilateral) female and 6 male patients with a mean age of 66.5 (range: 41–89) years. The mean follow-up period was 30 (range: 24–37) months. Eighteen knees (72%) had evidence of trochlear dysplasia. The anterior trochlear line was on average, 7.71 (range: 3.3–11.3) degrees, internally rotated to the surgical transepicondylar axis and on average 2.9 (range: 0.2–6.5) degrees internally rotated to the posterior condylar line. The preoperative planning range was 4-degree internal to 4-degree external rotation, 4-degree varus to 6-degree valgus, and 7-degree flexion to 3-degree extension. The average difference between preoperative planning and intraoperative implant position was 0.43 degrees for rotation (r = 0.93), 0.99 degrees for varus/valgus (r = 0.29), 1.26 degrees for flexion/extension (r = 0.83), and 0.34 mm for proudness (r = 0.80). Six patients (24%) had a different size component from their preoperative plan (r = 0.98). The mean preoperative Oxford Knee Score (OKS) was 16 and the mean postoperative OKS was 42. No patient had implant-related revision surgery or any radiological evidence of implant loosening at final follow-up. Our early results of robotic PFA are promising. Preoperative Mako planning correlates closely with intraoperative implant positioning. Longer follow-up is needed to assess long-term patient outcomes and implant survivorship.

Introduction There is controversy if direct to comprehensive center “mothership” (MS) or stopping at primary center for thrombolysis before transfer to comprehensive center “drip-and- ship” (DS) are best models of treatment of acute stroke. In this study, we compare MS and DS models to evaluate the best option of functional outcome. Methods Studies between 1990 and 2020 were extracted from online electronic databases. We compared the clinical outcomes, critical time measurements, functional independence and mortality were then compared. Results A total of 7,824 patients’ data were retrieved from 13 publications (3 randomized control trials and 10 retrospective ones). 4,639 (59.3%) patients were treated under MS model and 3,185 (40.7%) followed the DS model with mean age of 70.01±3.58 vs. 69.03±3.36; p< 0 .001, respectively. The National Institute Health Stroke Scale was 15.57±3.83 for the MS and 15.72±2.99 for the DS model (p=<0.001). The mean symptoms onset-to-puncture time was significantly shorter in the MS group compared to the DS (159.69 min vs. 223.89 min; p=<0.001, respectively). Moreover, the collected data indicated no significant difference between symptom’s onset to intravenous (IV) thrombolysis time and stroke onset-to-successful recanalization time (p=0.205 and p=<0.001, respectively). Patients had significantly worse functional outcome [modified rankin score (mRS)] (3-6) at 90-days in the DS model [Odds Ratio (OR): 1.47, 95% Confidence Interval (CI): 1.13-1.92, p<0.004] and 1.49-folds higher likelihood of symptomatic intracerebral hemorrhage (OR: 1.49, 95%CI: 1.22-1.81, p<0.0001) compared to MS. However, there were no statistically significant difference in terms of mortality (OR: 1.16, 95%CI: 0.87-1.55, p=0.32) and successful recanalization (OR: 1.12, 95%CI: 0.76-1.65, p=0.56) between the two models of care. Conclusion Patients in the MS model have significantly improved functional independence and recovery. Further studies are needed as the data from prospectively randomized studies is not of sufficient quality to make definite recommendations.

Abstract Background Optimal blood pressure (BP) management during endovascular stroke treatment in patients with large-vessel occlusion is not well established. We aimed to investigate associations of BP during different phases of endovascular therapy with reperfusion and functional outcome. Methods We performed a post hoc analysis of a single-center prospective study that evaluated a new simplified procedural sedation standard during endovascular therapy (Keep Evaluating Protocol Simplification in Managing Periinterventional Light Sedation for Endovascular Stroke Treatment). BP during endovascular therapy in patients was managed according to protocol. Data from four different phases (baseline, pre-recanalization, post recanalization, and post intervention) were obtained, and mean BP values, as well as changes in BP between different phases and reductions in systolic BP (SBP) and mean arterial pressure (MAP) from baseline to pre-recanalization, were used as exposure variables. The main outcome was a modified Rankin Scale score of 0–2 three months after admission. Secondary outcomes were successful reperfusion and change in the National Institutes of Health Stroke Scale score after 24 h. Multivariable linear and logistic regression models were used for statistical analysis. Results Functional outcomes were analyzed in 139 patients with successful reperfusion (defined as thrombolysis in cerebral infarction grade 2b–3). The mean (standard deviation) age was 76 (10.9) years, the mean (standard deviation) National Institutes of Health Stroke Scale score was 14.3 (7.5), and 70 (43.5%) patients had a left-sided vessel occlusion. Favorable functional outcome (modified Rankin Scale score 0–2) was less likely with every 10-mm Hg increase in baseline (odds ratio [OR] 0.76, P = 0.04) and pre-recanalization (OR 0.65, P = 0.011) SBP. This was also found for baseline (OR 0.76, P = 0.05) and pre-recanalization MAP (OR 0.66, P = 0.03). The maximum Youden index in a receiver operating characteristics analysis revealed an SBP of 163 mm Hg and MAP of 117 mm Hg as discriminatory thresholds during the pre-recanalization phase to predict functional outcome. Conclusions In our protocol-based setting, intraprocedural pre-recanalization BP reductions during endovascular therapy were not associated with functional outcome. However, higher intraprocedural pre-recanalization SBP and MAP were associated with worse functional outcome. Prospective randomized controlled studies are needed to determine whether BP is a feasible treatment target for the modification of outcomes.

ABSTRACT Twelve healthy volunteers participated in this randomized crossover study to compare the concentrations and recovery levels of fleroxacin and pefloxacin in urine and to assess their bactericidal activities against 12 strains of urinary pathogens with different susceptibilities over a wide range of MICs. The volunteers received a single oral dose of 400 mg of fleroxacin or 800 mg of pefloxacin. The mean cumulative renal excretion of unchanged fleroxacin,N-demethyl-fleroxacin, and N-oxide-fleroxacin accounted for 67, 7, and 6% of the total dose, respectively. The total urinary recovery of pefloxacin and the active metabolite norfloxacin was 34%. In the time-kill and the urinary bactericidal titer (UBT) studies, only the subjects’ urine not supplemented with broth was used. With most tested organisms and both quinolones it took more than 8 h to achieve a reduction in CFU of 99.9% (3 log units). Overall, there was a good correlation between UBTs and MICs for the strains. Against Escherichia coli ATCC 25922 the median UBTs were similar for both antibiotics and at least 1:8 for 96 h; against the E. coli strain for which the MIC was 0.5 μg/ml the UBT was at least 1:4 for 48 h. The UBTs of both drugs against Klebsiella pneumoniae were at least 1:16 for 72 h. The UBTs for Staphylococcus aureus (the MIC for which was 16 μg/ml) of both antibiotics were low, and in some of the samples, no bactericidal titers were observed. UBTs for Proteus mirabilis of pefloxacin are significantly higher than those of fleroxacin. For Pseudomonas aeruginosa the median UBTs were present for the 24-to-48-h interval. The same is true forEnterococcus faecalis. Against Staphylococcus saprophyticus, UBTs were present for at least 48 h with both quinolones. Overall, a single oral dose of 400 mg of fleroxacin exhibits UBTs comparable to those of 800 mg of pefloxacin. Therefore, it may be expected that half of the dose of fleroxacin gives comparable results in the treatment of urinary tract infections; this should be substantiated in comparative clinical trials.

Purpose: Fixation of displaced midshaft clavicle is well known to decrease nonunion, malunion and shoulder disability as compared to nonoperative treatment. This study was done to compare the clinical and functional outcome of group 1 clavicle fractures treated with anatomic locking plates (ALP) versus Titanium elastic nail (TEN). Methods: We studied patients presenting with displaced midshaft clavicle fractures treated with ALP or TEN. The study period was from Jan 2013 to Dec 2016. Patients were reviewed and at each visit clinical and radiological progress of union was noted, complications if any were noted, functional assessment was done using the quick Dash score and Constant Murley score. Results: A total of 116 patients met our inclusion criteria. 62 patients were treated with TEN and 54 with ALP. Bony union was achieved at an average of 11.8 weeks in the TENS group and 12.8 weeks in the ALP group post operatively and this was found to be significant. The mean postoperative Constant Murley score in the ALP and the TEN groups were 92.8 (range 80–97), and 93.7 (82–97) respectively. The mean postoperative quick dash score in the ALP and TEN groups were 2.48(range from 0 to 6.8) and 2.1 (range 0–9.1) respectively. Conclusion: Both Anatomical locking plate and TEN are good options for the treatment of non-comminuted mid clavicular fractures as they have a similar functional outcome. TEN nail insertion has the advantage of being minimally invasive, having a faster union time and may be recommended in midshaft clavicle fractures without comminution.

Baseline Characteristics

Background and Purpose: Hemispheric location might influence outcome after intracerebral hemorrhage (ICH). INTERACT suggested higher short-term mortality in right hemispheric ICH, yet statistical imbalances were not addressed. This study aimed at determining the differences in long-term functional outcome in patients with right- vs. left-sided ICH with a priori-defined sub-analysis of lobar vs. deep bleedings. Methods: Data from a prospective hospital registry were analyzed including patients with ICH admitted between January 2006 and August 2014. Data were retrieved from institutional databases. Outcome was assessed using the modified Rankin Scale (mRS) score. Outcome measures (long-term mortality and functional outcome at 12 months) were correlated with ICH location and hemisphere, and the imbalances of baseline characteristics were addressed by propensity score matching. Results: A total of 831 patients with supratentorial ICH (429 left and 402 right) were analyzed. Regarding clinical baseline characteristics in the unadjusted overall cohort, there were differences in disfavor of right-sided ICH (antiplatelets: 25.2% in left ICH vs. 34.3% in right ICH; p < 0.01; previous ischemic stroke: 14.7% in left ICH vs. 19.7% in right ICH; p = 0.057; and presence/extent of intraventricular hemorrhage: 45.0% in left ICH vs. 53.0% in right ICH; p = 0.021; Graeb-score: 0 [0-4] in left ICH vs. 1 [0-5] in right ICH; p = 0.017). While there were no differences in mortality and in the proportion of patients with favorable vs. unfavorable outcome (mRS 0-3: 142/375 [37.9%] in left ICH vs. 117/362 [32.3%] in right ICH; p = 0.115), patients with left-sided ICH showed excellent outcome more frequently (mRS 0-1: 64/375 [17.1%] in left ICH vs. 43/362 [11.9%] in right ICH; p = 0.046) in the unadjusted analysis. After adjusting for confounding variables, a well-balanced group of patients (n = 360/hemisphere) was compared showing no differences in long-term functional outcome (mRS 0-3: 36.4% in left ICH vs. 33.9% in right ICH; p = 0.51). Sub-analyses of patients with deep vs. lobar ICH revealed also no differences in outcome measures (mRS 0-3: 53/151 [35.1%] in left deep ICH vs. 53/165 [32.1%] in right deep ICH; p = 0.58). Conclusion: Previously described differences in clinical end points among patients with left- vs. right-hemispheric ICH may be driven by different baseline characteristics rather than by functional deficits emerging from different hemispheric functions affected. After statistical corrections for confounding variables, there was no impact of hemispheric location on functional outcome after ICH.

The Impact

Background and Purpose: The impact of CHADS 2 score on neurological severity in patients with stroke during oral anticoagulant (OAC) has not yet been elucidated. We investigated the association between pre-stroke CHADS 2 score and severity on admission and functional outcome in acute cardioembolic stroke due to AF during OAC. Methods: We conducted an investigator-initiated, multicenter, prospective, observational cohort study, PASTA registry. One thousand forty-three patients with transient ischemic attack, ischemic stroke, and ICH who were taking OACs were prospectively enrolled in 25 medical institutions throughout Japan. We compared the clinical characteristics including severity onset and discharge outcome between low CHADS 2 score group (<2), and high CHADS 2 score group (≥2) in patients with cardioembolic stroke due to AF. Result: A total of 548 patients (237 women; median age 80 [quartiles 74-85] years) were enrolled. Of these, there were 76 patients (14%) in low CHADS 2 group and 472 (86%) in high CHADS 2 score group (Fig A). Along with increase of pre-stroke CHADS 2 score, NIHSS score was gradually increased (Fig B). Low CHADS 2 score group was associate with good outcome than high CHADS 2 group (p<0.001, Fig C). Age (p<0.001), male (p<0.001), pre-stroke CHADS 2 score (p<0.001), and initial NIHSS score (p<0.001) were significantly higher in non-excellent outcome (mRS≥2) group than excellent outcome group (mRS<2). In contrast, creatinine clearance and body weight were higher in excellent outcome group (Both p<0.001). Multivariate logistic regression analysis indicated that high pre-stroke CHADS 2 score independently associated with higher NIHSS score (NIHSS score≥6; OR 1.55, 95%CI 1.02-2.36, p=0.041) and non-excellent outcome (OR 1.94, 95%CI 1.01-3.80, p=0.047). Conclusion: The present study suggests that the pre-stroke CHADS 2 score should be useful for the prediction of clinical outcomes in patients with cardioembolic stroke due to AF even taking OAC.
