Aims

The aims of this study were first, to determine if adding fusion to a decompression of the lumbar spine for spinal stenosis decreases the rate of radiological restenosis and/or proximal adjacent level stenosis two years after surgery, and second, to evaluate the change in vertebral slip two years after surgery with and without fusion.

Aims

Two-stage exchange revision total hip arthroplasty (THA) performed in case of periprosthetic joint infection (PJI) has been considered for many years as being the gold standard for the treatment of chronic infection. However, over the past decade, there have been concerns about its safety and its effectiveness. The purposes of our study were to investigate our practice, collecting the overall spacer complications, and then to analyze their risk factors.

Aims

The primary aim of this study was to determine the rates of return to work (RTW) and sport (RTS) following a humeral shaft fracture. The secondary aim was to identify factors independently associated with failure to RTW or RTS.

This prospective study explores the outcomes of the Forth Valley Protocol (FVP) for the management of acute Achilles tendon ruptures. The protocol uses ultrasound as the primary mechanism to guide treatment. All patients presenting with acute tendoachilles rupture over a three-year period were included. Patients under 18 years of age, chronic ruptures, or prior surgery to the Achilles tendon were excluded. Patients with a gap ≤2cm had conservative management following an Early Rehabilitation Protocol (ERP) and >2cm underwent surgery (if an appropriate surgical candidate). Achilles Tendon Rupture Scores (ATRS) were obtained retrospectively. Fischer's exact test was used to determine statistical significance. 158 patients were included with a mean age of 53 (range 20–89). Ultrasound scans were obtained for 121 patients (76.5%), demonstrating a mean tendon gap of 1.61cm. 143 patients managed conservatively and 15 surgically. The overall re-rupture rate was 3.8% (n=6). All the re-ruptures occurred in patients treated conservatively, but this was not found to be statistically significant (n=6, P=1.0). The overall complication rate (excluding re-ruptures) was 1.9%. ATRS was comparable between both treatment modalities (P=0.382, 0.422), with a mean score of 86.6 in the conservative group and 81.4 in the surgical group. The FVP demonstrates low re-rupture and complication rates in line with other published studies. Patients with gaps ≤2.0cm on the ultrasound can be successfully treated conservatively with an ERP. This has potential benefits in terms improved patient outcomes, satisfaction, and preservation of resources

Introduction. A key outcome measured by national joint registries are revision events. This informs best practice and identifies poor-performing surgical devices. Although registry data often record reasons for revision arthroplasty, interpretation is limited by lack of standardised definitions of revision reasons and objective assessment of radiologic and laboratory parameters. Our study aim was to compare reasons for unicompartmental knee arthroplasty (UKA) revision reported to the New Zealand Joint Registry (NZJR) with reasons identified by independent clinical review. Methods. A total of 2,272 patients undergoing primary medial and lateral UKA at four large tertiary hospitals between 2000 and 2017 were included. A total of 158 patients underwent subsequent revision with mean follow-up of 8 years. A systematic review of clinical findings, radiographs and operative data was performed to identify revision cases and to determine the reasons for revision using a standardised protocol. These were compared to reasons reported to the NZJR using Chi-squared and Fisher exact tests. Results. Osteoarthritis progression was the most common reason for revision on systematic clinical review (30%), however this was underreported to the registry (4%, p<0.001). A larger proportion of revisions reported to the registry were for ‘unexplained pain’ (30% of cases vs. 4% on clinical review, p<0.001). A reason for revision was not reported to the registry for 24 (15%) of cases. Discussion and Conclusion. We found significant inaccuracies in registry-reported reasons for revision following UKA. These included over-reporting of ‘unexplained pain’, under-reporting of osteoarthritis progression, and failure to identify a reason for revision. Efforts to improve registry capture of revision reasons for UKA should focus on increasing accuracy in these three areas. This could be addressed through standardised recording methods and tailored revision reason options for UKA for surgeons to select when recording the reasons

Aim. Prosthetic joint infection (PJI) is a devastating and costly complication of total joint arthroplasty (TJA). Use of extended oral antibiotic prophylaxis (EOAP) has become increasingly popular in the United States following a highly publicized study (Inabathula et al) from a single center demonstrating a significant protective effect (81% reduction) against PJI in ‘high-risk’ patients. However, these results have not been reproduced elsewhere and EOAP use directly conflicts with current antibiotic stewardship efforts. In order to study the role of EOAP in PJI prevention, consensus is needed for what defines ‘high-risk’ patients. The revision TJA (rTJA) population is an appropriate group to study due to having a higher incidence of PJI. The purpose of the current study was to rigorously determine which preoperative conditions described by Inabathula et al. (referred to as Inabathula criteria (IBC)) confer a higher rate of PJI in patients undergoing aseptic rTJA. Method. 2,256 patients that underwent aseptic rTJA at a single high-volume institution between 2016–2022 were retrospectively reviewed. Patient demographics and comorbidities were recorded to determine if they had 1 or more ‘IBC’, a long list of preoperative conditions including autoimmune diseases, active smoking, body mass index (BMI)>35, diabetes mellitus, and chronic kidney disease (CKD). Reoperation for PJI at 90-days and 1-year was recorded. Chi-squared or Fischer's exact tests were calculated to determine the association between preoperative presence/absence of IBC and PJI. Multivariable logistic regressions were conducted to determine if specific comorbidities within the IBC individually conferred an increased PJI risk. Results. 1223 patients (54.2%) had at least one IBC condition. IBC-positive patients were more likely to be female, have an increased ASA score, and higher BMI. IBC-positive patients had a significant increase in PJI risk at both 90-days (relative risk (RR)=2.32, p<0.0001) and 1-year (RR=2.14, p=0.002) versus IBC-negative patients. Within IBC-positive patients, every additional IBC condition conferred a 1.8× odds increase for 90-day PJI (p<0.0001), and 1.76× odds increase in 1-year PJI (p<0.0001). Multivariable logistic regression identified active smoking, BMI>35, CKD, and diabetes mellitus as being independently associated with PJI development (p<0.05). Conclusions. Over half of rTJA patients meet IBC and could be eligible to receive EOAP in the United States. However, the specific presence of active smoking, BMI>35, CKD, and diabetes mellitus appear to be responsible for the increased risk of PJI. Prospective studies investigating EOAP use for patients with these specific conditions are urgently needed to prevent unnecessary antibiotic use

The management of periprosthetic distal femur fractures is an issue of increasing importance for orthopaedic surgeons. Because of the expanding indications for total knee arthroplasty (TKA) and an aging population with increasingly active lifestyles there has been a corresponding increase in the prevalence of these injuries. The management of these fractures is often complex because of issues with obtaining fixation around implants and dealing with osteopenic bone or compromised bone stock. In addition, these injuries frequently occur in frail, elderly patients, and the early restoration of function and ambulation is critical in these patients. There remains substantial controversy with respect to the optimal treatment of periprosthetic distal femur fractures, with some advocating for Locked Plating (LP), others Retrograde Intramedullary Nailing (RIMN) and finally those who advocate for Distal Femoral Replacement (DFR). The literature comparing these treatments, has been infrequent, and commonly restricted to single-center studies. The purpose of this study was to retrospectively evaluate a large series of operatively treated periprosthetic distal femur fractures from multiple centers and compare treatment strategies. Patients who were treated operatively for a periprosthetic distal femur fracture at 8 centers across North America between 2003 and 2018 were retrospectively identified. Baseline characteristics, surgical details and post-operative clinical outcomes were collected from patients meeting inclusion criteria. Inclusion criteria were patients aged 18 and older, any displaced operatively treated periprosthetic femur fracture and documented 1 year follow-up. Patients with other major lower extremity trauma or ipsilateral total hip replacement were excluded. Patients were divided into 3 groups depending on the type of fixation received: Locked Plating, Retrograde Intramedullary Nailing and Distal Femoral Replacement. Documented clinical follow-up was reviewed at 2 weeks, 3 months, 6 months and 1 year following surgery. Outcome and covariate measures were assessed using basic descriptive statistics. Categorical variables, including the rate of re-operation, were compared across the three treatment groups using Fisher Exact Test. In total, 121 patients (male: 21% / female: 79%) from 8 centers were included in our analysis. Sixty-seven patients were treated with Locked Plating, 15 with Retrograde Intramedullary Nailing, and 39 were treated with Distal Femoral Replacement. At 1 year, 64% of LP patients showed radiographic union compared to 77% in the RIMN group (p=0.747). Between the 3 groups, we did not find any significant differences in ambulation, return to work and complication rates at 6 months and 1 year (Table 1). Reoperation rates at 1 year were 27% in the LP group (17 reoperations), 16% in the DFR group (6 reoperations) and 0% in the RIMN group. These differences were not statistically significant (p=0.058). We evaluated a large multicenter series of operatively treated periprosthetic distal femur fractures in this study. We did not find any statistically significant differences at 1 year between treatment groups in this study. There was a trend towards a lower rate of reoperation in the Retrograde Intramedullary Nailing group that should be evaluated further with prospective studies.

Retrospectively to analyse factors contributing to the development of hyperextension deformity after distal surgical lengthening of hamstrings in cerebral palsy. In the cohort of 51 diparetic patients (98 operated knees ) surgically treated for fixed flexion deformity at least five yers before this study was contemplated, the range of of hyperextension of the knee was measured. According to surgical technique two subgroups were differentiated:. A./ Simple cutting of gracilis and semitendinosus, followed by fractional lengthening of semimembranosus and biceps femoris. B./ Proximal stumps of gracilis and semitendinosus after its transverse division were anchored to fractionally lengthened semimembranosus. Assessment involved: Measurement of hyperextension of the knee in lying and standing position and by walking using video-documentation. Values of Bleck popliteal angle before and after operation were estimated. This cohort did not involve any case with residual fixed plantar flexion of the foot. Both surgical subgroups were compared for occurence of hyperextension deformity > 5° in lying, standing positions and by walking. Testing by Fisher exact test did not show any statistical difference in all three compared situations (p > 0,05). The occurence of hyperextension > 5°in lying position was found in 5 knees ( 5,1 %), in standing position in 8 knees ( 8,2 %) and by walking during stance phase in 12 knees (12,3 %). In no case hyperextension of the knee exceeded 15°. Statistical testing between the postoperative Bleck popliteal angle ( stratified into classes below 20° and over 20°) and the occurence of hyperextension deformity did not show in Fisher exact test any statistical significance. On the other side the testing between postoperative Bleck popliteal angle ( stratified as above) and the type of surgery showed statistical significancy in Fisher exact test. Simple cutting of gracilis and semitendinosus brought about oftener the lower values of Bleck popliteal angle below 20°. It seems that the role of type of treating superficial flexors in the ways used in this study was not so much decisive for development of hyperextension deformity

Perioperative glucocorticoids have been used as a successful non-opioid analgesic adjunct for various orthopaedic procedures. Here we describe an ongoing randomized control trial assessing the efficacy of a post-operative methylprednisolone taper course on immediate post-operative pain and function following surgical distal radius fixation. We hypothesize that a post-operative methylprednisolone taper course following distal radius fracture fixation will lead to improved patient pain and function. This study is a randomized control trial (NCT03661645) of a group of patients treated surgically for distal radius fractures. Patients were randomly assigned at the time of surgery to receive intraoperative dexamethasone only or intraoperative dexamethasone followed by a 6-day oral methylprednisolone (Medrol) taper course. All patients received the same standardized perioperative pain management protocol. A pain journal was used to record visual analog pain scores (VAS-pain), VAS-nausea, and number of opioid tablets consumed during the first 7 post-operative days (POD). Patients were seen at 2-weeks, 6-weeks, and 12-weeks post-operatively for clinical evaluation and collection of patient reported outcomes (Disabilities of the Arm, Shoulder and Hand Score [qDASH]). Differences in categorical variables were assessed with χ2 or Fischer's exact tests. T-tests or Mann-Whitney-U tests were used to compare continuous data. Forty-three patients were enrolled from October 2018 to October 2019. 20 patients have been assigned to the control group and 23 patients have been assigned to the treatment group. There were no differences in age (p=0.7259), Body Mass Index (p=0.361), race (p=0.5605), smoking status (p=0.0844), or pre-operative narcotic use (p=0.2276) between cohorts. 83.7% (n=36) of patients were female and the median age was 56.9 years. No differences were seen in pre-operative qDASH (p=0.2359) or pre-operative PRWE (p=0.2329) between groups. In the 7 days following surgery, patients in the control group took an average of 16.3 (±12.02) opioid tablets, while those in the treatment group took an average of 8.71 (±7.61) tablets (p=0.0270). We see that significant difference in Opioid consumption is formed at postoperative day two between the two groups with patients in the control group taking. Patient pain scores decreased uniformly in both groups to post-operative day 7. Patient pain was not statistically from POD0 to POD2 (p=0.0662 to 0.2923). However, from POD4 to POD7 patients receiving the methylprednisolone taper course reported decreased pain (p=0.0021 to 0.0497). There was no difference in qDASH score improvement at 6 or 12 weeks. Additionally, no differences were seen for wrist motion improvement at 6 or 12 weeks. A methylprednisolone taper course shows promise in reducing acute pain in the immediate post-operative period following distal radius fixation. Furthermore, although no statistically significant reductions in post-operative opioid utilization were noted, current trends may become statistically significant as the study continues. No improvements were seen in wrist motion or qDASH and continued enrollment of patients in this clinical trial will further elucidate the role of methylprednisolone for these outcomes

Autologous micro-fragmented adipose tissue (MFAT) for the treatment of symptomatic knee osteoarthritis (OA) is gaining interest although there is still a lack of supportive data on safety and clinical efficacy. This study primarily aimed to identify patient- and pathology-related parameters to tighten patient selection criteria for future clinical MFAT application. Secondly, the overall (1) therapeutic response rate (TRR), (2) short-term clinical effect, (3) effect durability and (4) therapeutic safety was investigated at a minimal follow-up of 1 year. Sixty-four subjects (91 knees) with symptomatic knee OA (mild-severe on MRI) were enrolled in a prospective single-centre case series. Ethical approval was obtained from the local and academic ethical committee (#B300201733775). After liposuction, the adipose tissue was mechanically processed in a Lipogem® device which eventually produced 6–9cc MFAT. Subjects were clinically assessed by means of the KOOS, NRS, UCLA and EQ-5D at baseline and 1, 3, 6 and 12 months after injection. Adverse events were meticulously recorded. The TRR was defined according to the OMERACT-OARSI criteria. A baseline MRI was scored following the MOAKS system. Paired sample t-tests, independent t-test and Fischer's exact test were applied on appropriate variables. Multiple regression models were fit separately for patient-and pathology-specific factors. Significance level was set at α=0.05. The overall TRR was 66% at 3 months and 50% at 12 months after injection. Subgroup analysis revealed that specifically patients with no-mild bone marrow lesions (BML) had a TRR of 88% at 3 months and 75% at 12 months after MFAT injection. Therapy responders at these timepoints improved with 29.3±14.1 points and 30.8±15.3 points on KOOS pain, while non-responders deteriorated mildly. All clinical scores were significantly higher at follow-up compared to baseline (p<0.05). BMI (factor 0.17, p=0.002) and age (factor −0.48, p=0.048) were prognosticators for the TRR% at 1 month and for absolute KOOS pain improvement at 6 months, respectively. Posterior horn lesions (PHL) in the medial meniscus (p<0.001) and bone marrow lesions (p=0.003) were negative prognosticators for the TRR at respectively 6 and 12 months post-injection. An inflammatory reaction (pain, swelling or stiffness) to MFAT was reported in 79% knees and resolved spontaneously within 16.6±13.5 days after administration. The study showed a durable and satisfying TRR (up to 75% at 1 year in selected patients without BML) and clinical improvement after a single intra-articular injection with autologous MFAT. The availability of an index knee MRI is mandatory to select MFAT patients, preferably with no or mild BML and without PHL of the medial meniscus. High BMI and younger age are associated with better early outcomes. In comparison to other injection therapies such as cortisone, hyaluronic acid and PRP, MFAT appears very attractive with an effect durability of at least 1 year

Olecranon Osteotomy is a common approach used in the management of intraarticular distal humerus fractures. Significant complication rates have been associated with this procedure, including non-union rates of 0–13% and implant removal rates between 12–86%. This study is a multicentre retrospective study involving the largest cohort of olecranon osteotomies in the literature, examining implant fixation types, removal rates and associated complications. Patients were identified between 2007 and 2017 (minimum one year follow-up) via Canadian Classification of Health Interventions (CCI) coding and ICD9/10 codes by our health region's data information service. CCI intervention codes were used to identify patients who underwent surgery for their fracture with an olecranon osteotomy. Reasons for implant removal were identified from a chart review. Our primary outcome was implant removal rates. Categorical data was assessed using Chi square test and Fischer's Exact test. Ninety-nine patients were identified to have undergone an olecranon osteotomy for treatment of a distal humerus fracture. Twenty patients had their osteotomy fixed with a plate and screws and 67 patients were fixed with a tension band wire. Eleven patients underwent “screw fixation”, consisting of a single screw with or without the addition of a wire. One patient had placement of a cable-pin system. Of patients who underwent olecranon osteotomy fixation, 34.3% required implant removal. Removal rates were: 28/67 for TBW (41.8%), 6/20 plates (30%), 0/1 cable-pin and 0/11 for osteotomies fixed with screw fixation. Screw fixation was removed less frequently than TBW p<.006. TBW were more commonly removed than all other fixation types p<.043. Screws were less commonly removed than all other fixation types p<.015. TBW were more likely to be removed for implant irritation than plates, p<.007, and all other implants p<.007. The average time to removal was 361 days (80–1503 days). A second surgeon was the surgeon responsible for the removal in 10/34 cases (29%). TBWs requiring removal were further off the olecranon tip than those not removed p=.006. TBWs were associated with an OR of 3.29 (CI 1.10–9.84) for implant removal if implanted further than 1mm off bone. Nonunion of the osteotomy occurred in three out of 99 patients (3%). K-wires through the anterior ulnar cortex did not result in decreased need for TBW removal. There was no relation between plate prominence and the need for implant removal. There was no association between age and implant removal. The implant removal rate was 34% overall. Single screw fixation was the best option for osteotomy fixation, as 0/11 required hardware removal, which was statistically less frequent than TBW at 28/67. Screw fixation was removed less frequently than TBW and screw fixation was less commonly removed than all other fixation types. Only 6/20 (30%) plates required removal, which is lower than previously published rates. Overall, TBW were more commonly removed than all other fixation types and this was also the case if hardware irritation was used as the indication for removal. Nonunion rates of olecranon osteotomy were 3%

Introduction. Soft tissue releases are often required to correct deformity and achieve gap balance in total knee arthroplasty (TKA). However, the process of releasing soft tissues can be subjective and highly variable and is often perceived as an ‘art’ in TKA surgery. Releasing soft tissues also increases the risk of iatrogenic injury and may be detrimental to the mechanically sensitive afferent nerve fibers which participate in the regulation of knee joint stability. Measured resection TKA approaches typically rely on making bone cuts based off of generic alignment strategies and then releasing soft tissue afterwards to balance gaps. Conversely, gap-balancing techniques allow for pre-emptive adjustment of bone resections to achieve knee balance thereby potentially reducing the amount of ligament releases required. No study to our knowledge has compared the rates of soft tissue release in these two techniques, however. The objective of this study was, therefore, to compare the rates of soft tissue releases required to achieve a balanced knee in tibial-first gap-balancing versus femur-first measured-resection techniques in robotic assisted TKA, and to compare with release rates reported in the literature for conventional, measured resection TKA [1]. Methods. The number and type of soft tissue releases were documented and reviewed in 615 robotic-assisted gap-balancing and 76 robotic-assisted measured-resection TKAs as part of a multicenter study. In the robotic-assisted gap balancing group, a robotic tensioner was inserted into the knee after the tibial resection and the soft tissue envelope was characterized throughout flexion under computer-controlled tension (fig-1). Femoral bone resections were then planned using predictive ligament balance gap profiles throughout the range of motion (fig-2), and executed with a miniature robotic cutting-guide. Soft tissue releases were stratified as a function of the coronal deformity relative to the mechanical axis (varus knees: >1° varus; valgus knees: >1°). Rates of releases were compared between the two groups and to the literature data using the Fischer's exact test. Results. The overall rate of soft tissue release was significantly lower in the robotic gap-balancing group, with 31% of knees requiring one or more releases versus 50% (p=0.001) in the robotic measured resection group and 66% (p<0.001) for conventional measured resection (table-1) [1]. When comparing as a function of coronal deformity, the difference in release rates for robotic gap-balancing was significant when compared to the conventional TKA literature data (p<0.0001) for all deformity categories, but only for varus and valgus deformities for robotic measured resection with the numbers available (varus: 33% vs 50%, p=0.010; neutral 11% vs 50%, p=0.088, valgus 27% vs 53%, p=0.048). Discussion. Robotic-assisted tibial-first gap-balancing techniques allow surgeons to plan and adjust femoral resections to achieve a desired gap balance throughout motion, prior to making any femoral resections. Thus, gap balance can be achieved through adjustment of bone resections, which is accurate to 1mm/degree with robotics, rather than through manual releasing soft tissues which is subjective and less precise. These results demonstrated that the overall rate of soft tissue release is reduced when performing TKA with predictive gap-balancing and a robotic tensioning system.

Background. Prior research has shown that depression negatively impacts outcomes after total hip arthroplasty (THA); however, arthroplasty patients may also have depressive symptoms without an established diagnosis. The purpose of this study was to determine whether the Patient Health Questionnaire-2 (PHQ-2), a two-question depression screener, correlates with joint-specific symptom improvement after primary THA. Methods. This was a prospective cohort study. Patients completed the PHQ-2 and the Hip Disability and Osteoarthritis Outcome Score - Joint Replacement (HOOS-JR) prior to THA, with follow-up at 6 weeks and 6 months. An a priori power analysis determined a sample size of 31 would detect an effect size of 0.5 with a power of 0.80. We used previously established minimum clinically important difference (MCID) values for HOOS-JR. Continuous variables were analyzed with t-tests or Mann-Whitney tests while categorical variables were analyzed with Chi square or Fisher exact tests. Results. 77 patients were enrolled. 23 (30%) had a PHQ-2 of 3 or higher, indicating a high likelihood of depression. HOOS-JR scores were lower in the high PHQ-2 group at baseline and at six weeks (p<0.05). The two groups were equally likely to reach MCID at six weeks and six months, and there was no significant difference between absolute HOOS-JR scores at six months. Discussion. Patients with greater depressive symptoms have an equal likelihood of achieving MCID after THA, but worse absolute pain and function at baseline and six weeks after surgery. Administering the PHQ-2 may help surgeons better counsel their patients as to what to expect from surgery. Targeted mental health treatment perioperatively could allow these patients to achieve an even greater improvement in their long-term outcomes

Introduction: The problem of ingrowing toenails is worldwide, affecting all age groups. The exact incidence in children is difficult to measure. The aim of this study was to review the different surgical modalities for ingrown toenails in the paediatric age group in a hospital setting. Methods: We reviewed case series of 66 children aged between 9 months and 16 yrs. In total there were 89 affected toes operated upon between 1995 and 2001. The patients were followed up for up to 18 months. All procedures were carried out under general anaesthetic. The treatment methods practised were:. Nail avulsion with or without nail matrix ablation using phenol. Wedge excision of the nail with or without nail matrix ablation using phenol or thermal ablation. RESULTS: We performed statistical analysis using Fischer’s exact test with the level of significance at P value 0.05. We found the recurrence rate to be 3% for those treated with wedge excision alone compared to 30% when treated with wedge excision and phenol ablation (p=0.001). We also applied the same Fischer’s exact test for rate of infection in all the groups. DISCUSSION: Ingrown toenails go through three stages- inflammation, infection and granulation. During the stage of inflammation, conservative measures in the past have been noted to be successful. In a hospital setting, most patients present in the second stage (infection). Nail avulsion is still commonly practised as a first line treatment. It provides good symptomatic relief in this stage but has been reported to have high rates of recurrence. We noted similar results (recurrence rate: 55%) in our study. Then patients present in the next stage with symptoms of chronic ingrowths i.e. previous infection and presence granulation tissue in the nail fold. The aim of treatment here is to remove the ingrown area along with the nail fold. Wedge excision with or without removal of nail matrix is a commonly performed procedure. There are various methods for removing the nail matrix namely surgical matrixectomy, chemical matrixectomy using phenol or sodium hydroxides, diathermic/electric cauterisation, laser. There are reports that show low recurrence rates with use of phenol. In this study we found recurrence and infection to be high when phenol was used as the ablative agent. We achieved cure rate of 97% when using wedge excision alone and 70% when phenol was used for nail matrix ablation. CONCLUSION: We advocate wedge excision as primary treatment of ingrowing toenails in children. We did not note a statistical significance in giving postoperative antibiotics but this has to correlate with the clinical presentation. We would not recommend phenol ablation of the nail matrix in the younger patient as it increases both infection and recurrence rates. The results of nail bed ablation with diathermy appear promising

Introduction. The obesity epidemic is a growing problem and must be considered with the projected increased demand for total hip arthroplasty (THA). Previous studies have reported increased complication rates after THA in the obese population, which has led to hesitation in offering surgery to this population. Moreover, some insurers are denying coverage for morbidly obese patients. While many consider obesity a “modifiable” risk factor, very few patients with advanced osteoarthritis have successfully lost substantial weight. The experience of centers that utilize systematic preoperative risk stratification tools and standardized postoperative total joint pathways may be underrepresented in prior studies. The aim of this study is to describe one surgeon's experience performing THA in morbidly and super-obese patient populations using an institutional preoperative Risk Stratification Tool (RST) and total joints pathway. Methods. We conducted a retrospective review of patients undergoing primary THA between May 2014 and December 2017 performed by a single surgeon at a tertiary care referral center. All patients were assessed preoperatively using an institutional RST and had a minimum of 90-day postoperative follow up. Patients were stratified by body mass index (BMI, kg/m. 2. ): non-obese (BMI < 30), obese (30–34), severely obese (35–39), morbidly obese (40–44), and super-obese (≥ 45). Primary outcomes were inpatient and 90-day complications. Continuous and binary parameters were analyzed by Kruskal-Wallis and Fisher exact tests. Logistic regression was additionally utilized to evaluate outcomes by BMI cohort. Results. A consecutive series of 368 patients met inclusion criteria across all BMI cohorts. There was significant variation with respect to age (P=0.001), BMI (P<0.001), diabetes (P=0.008), ASA class (P<0.001), and anesthesia type (P=0.003) (Table 1). Variation among BMI cohorts was also identified for several operative and postoperative parameters, including longer operative and in-room time and greater length of stay (P<0.001) (Table 2). Compared to non-obese patients, super-obese patients had 20.1 greater odds of return to OR within 90 days for superficial surgical site infection (SSI) or prolonged round drainage (P=0.008) (Table 3). Notably, morbidly and super-obese patients were not at significantly increased risk for inpatient intensive care unit (ICU) transfer, blood transfusion, 90-day emergency room visit, or 90-day readmission compared to their non-obese counterparts. For patients in whom 1-year follow-up was available, these differences between BMI cohorts remained insignificant. Conclusions. Patients with BMI>40 are more likely than non-obese patients to have increased postoperative rehabilitation needs but are not at increased risk for in-hospital complications. Super-obese patients have greater risk of superficial SSI or prolonged wound drainage than non-obese patients but are not at increased risk for revision or deep infection in any cohort. Use of a preoperative RST may help to mitigate postoperative complications and readmissions previously associated with morbid and super-obesity. We conclude that THA can be safely performed in super-obese patients and therefore care should not be denied to this population. Summary sentence. Total hip arthroplasty (THA) can be safely performed in morbidly and super-obese patients with the use of a preoperative risk stratification tool (RST) and total joints pathway.

Introduction. Orthopaedic trauma surgery is characterised by repetitive, forceful tasks that are physically demanding, thus theoretically increasing the risk of musculoskeletal injuries in these surgeons. The aim of this study is to assess prevalence, characteristics and impact of musculoskeletal disorders among orthopaedic trauma surgeons. Methods. A modified version of the physical discomfort survey was sent to surgeon members of the Orthopaedics Trauma Association (OTA) via e-mail. For data analysis, one-way ANOVA and Fisher Exact test were performed to compare the variables where appropriate. P values<0.05 were considered statistically significant. Results. A total of 86 surgeons completed the survey during the period of data collection. Of the respondents 84.9% were males and more than half were aged between 30–45 years old. The majority of musculoskeletal complaints and disorders were low back pain (29.3%), wrist or forearm tendinitis (18.0%), elbow lateral epicondylitis (15.4%), plantar fasciitis (14.7%). When data was analysed according to number of years in practice the results yielded a significant difference between the groups in both number of regions involved (p<0.05) and number of musculoskeletal disorders (p<0.05), as a higher proportion of these were documented in surgeons practicing for 16–20 years and more than 30 years. Also surgeons working in a private setting (p<0.005), surgeons working in more than one institute (p<0.005), increased number of regions involved (p<0.001) and increased number of musculoskeletal disorders (p<0.001) were significantly more likely to require time-off work. Conclusion. To our knowledge, our study is the first of its kind that shows a high percentage of orthopaedic trauma surgeons sustain occupational injuries some time in their careers. Cost of management and rehabilitation of these injuries, in addition to the amount of missed workdays due to these injuries indicate that these injuries have a significant economic burden on the health-care system

Bowel management following joint replacement is often neglected leading lot of patient distress, with the advent of the enhanced orthopedic rehabilitation program, there is a need of a guideline to ensure prompt and quick recovery of bowel habits before discharge. Our aim was to identify the incidence of constipation in joint replacement patients, to evaluate the current practice of bowel management and formulate a protocol for management of constipation to improve the practice. We conducted a prospective study of 50 patients who underwent joint replacement procedures at our institute between September and October 2015. Following initial audit, we formulated a protocol for bowel management, and performed a re-audit by collecting a prospective data of 50 patients. The statistical analysis was done and calculating the mean and standard deviation for continuous variable and Fischer's exact test was used and significance level was set at 0.05. Incidence of constipation was 88% and laxatives were prescribed in 42%. More importantly, there was no correlation between constipation and pre operative fasting (p Value 0.33), post operative fasting (p Value 0.1822), type of surgery (p value 1.00) and type of anaesthesia (p Value 0.27). Following introduction of bowel protocol the laxative prescription increased to 98% (Prophylactic in 81%), consequently the incidence of constipation reduced to 18%. Implementing bowel protocol significantly will improve the patient care and reduce the rate of complications
