Aims. This systematic review aimed to summarize the full range of complications reported following ankle arthroscopy and the frequency at which they occur. Methods. A computer-based search was performed in PubMed, Embase, Emcare, and ISI Web of Science. Two-stage title/abstract and full-text screening was performed independently by two reviewers. English-language original research studies reporting perioperative complications in a cohort of at least ten patients undergoing ankle arthroscopy were included.
Aims. Two-stage exchange arthroplasty is the most common definitive treatment for prosthetic joint infection (PJI) in the USA.
This work aimed at answering the following research questions: 1) What is the rate of mechanical complications, nonunion and infection for head/neck femoral fractures, intertrochanteric fractures, and subtrochanteric fractures in the elderly USA population? and 2) Which factors influence adverse outcomes? Proximal femoral fractures occurred between 1 January 2009 and 31 December 2019 were identified from the Medicare Physician Service Records Data Base. The Kaplan-Meier method with Fine and Gray sub-distribution adaptation was used to determine rates for nonunion, infection, and mechanical complications. Semiparametric Cox regression model was applied incorporating 23 measures as covariates to identify risk factors.Aims

The purpose of this study was to evaluate the incidence and analyze the trends of surgeon-reported complications following surgery for adolescent idiopathic scoliosis (AIS) over a 13-year period from the Scoliosis Research Society (SRS) Morbidity and Mortality database. All patients with AIS between ten and 18 years of age, entered into the SRS Morbidity and Mortality database between 2004 and 2016, were analyzed. All perioperative complications were evaluated for correlations with associated factors. Complication trends were analyzed by comparing the cohorts between 2004 to 2007 and 2013 to 2016.Aims
Methods
Intraarticular calcaneal fractures often need open reduction and internal fixation (ORIF) with plate osteosynthesis. The wound complication is one of the common problems encountered following this and affects the outcome adversely. Our study was done to assess how far postoperative slab/cast can avert wound complications. Out of 42 patients with unilateral intraarticular calcaneal fractures, 20 were offered postoperative slab/cast and this was continued for six weeks. The remaining 22 patients were not offered any plaster. All patients were followed-up for two years.Introduction
Methods
The aims of this study were to determine the rates of surgical complications, reoperations, and readmissions following herniated lumbar disc surgery, and to investigate the impact of sociodemographic factors and comorbidity on the rate of such unfavourable events. This was a longitudinal observation study. Data from herniated lumbar disc operations were retrieved from a large medical database using a combination of procedure and diagnosis codes from all public hospitals in Norway from 1999 to 2013. The impact of age, gender, geographical affiliation, education, civil status, income, and comorbidity on unfavourable events were analyzed by logistic regression.Aims
Patients and Methods
Over recent years hip arthroscopic surgery has
evolved into one of the most rapidly expanding fields in orthopaedic surgery.
Complications are largely transient and incidences between 0.5%
and 6.4% have been reported. However, major complications can and
do occur. This article analyses the reported complications and makes recommendations
based on the literature review and personal experience on how to
minimise them.
We systematically reviewed the published literature
on the complications of closing wedge high tibial osteotomy for
the treatment of unicompartmental osteoarthritis of the knee. Publications
were identified using the Cochrane Library, MEDLINE, EMBASE and
CINAHL databases up to February 2012. We assessed randomised (RCTs), controlled
group clinical (CCTs) trials, case series in publications associated
with closing wedge osteotomy of the tibia in patients with osteoarthritis
of the knee and finally a Cochrane review. Many of these trials
included comparative studies (opening wedge
Aims. The aims of the study were to analyze differences in surgical and oncological outcomes, as well as quality of life (QoL) and function in patients with ankle sarcomas undergoing three forms of surgical treatment, minor or major limb salvage surgery (LSS), or amputation. Methods. A total of 69 patients with ankle sarcomas, treated between 1981 and 2017 at two tumour centres, were retrospectively reviewed (mean age at surgery: 46.3 years (SD 22.0); 31 females (45%)). Among these 69 patients 25 were analyzed prospectively (mean age at latest follow-up: 61.2 years (SD 20.7); 11 females (44%)), and assessed for mobility using the Prosthetic Limb Users Survey of Mobility (PLUS-M; for amputees only), the Toronto Extremity Salvage Score (TESS), and the University of California, Los Angeles (UCLA) Activity Score. Individual QoL was evaluated in these 25 patients using the five-level EuroQol five-dimension (EQ-5D-5L) and Fragebogen zur Lebenszufriedenheit/Questions on Life Satisfaction (FLZ). Results. Of the total number of patients in the study, 22 (32%) underwent minor LSS and 22 (32%) underwent major LSS; 25 underwent primary amputation (36%).
Adverse events (AEs) are still a major problem in spinal surgery, despite advances in surgical techniques, innovative technologies available and the introduction of checklist and predictive score systems aimed at reducing surgical complications. We previously analysed the results of the introduction of the WHO Safety Surgical Checklist (SSC) in our Institution, comparing the incidence of complications between two periods: from January to December 2010 (without checklist) and from January 2011 and December 2012 (with checklist), in order to assess the checklist effectiveness. The sample size was 917 patients with an average of 30 months of follow-up.

Introduction. This study aims to evaluate the effect of using different types of fixator on the quality of callus and complications during distraction osteogenesis in patients with achondroplasia. Materials and Methods. Forty-nine achondroplasia patients with a minimum follow-up of 36 months who underwent limb lengthening between 2005 and 2017 with external fixator only were included. Thirty-three of the patients underwent lengthening using classical Ilizarov frame, while spatial frame used for sixteen. Regenerate quality is evaluated according to the Li classification on the X-ray taken one month after the end of the distraction.
Aim. Clavicular osteotomy was described as an adjunct to deltopectoral approach for improved exposure of the glenohumeral joint. This study aims to present contemporary outcomes and complications associated with the routine use of clavicular osteotomy by a single surgeon in a regional setting within New Zealand. Methods. A retrospective case series of patients who have undergone any shoulder arthroplasty for any indication between March 2017 to August 2022. This time period includes all patients who had clavicular osteotomy(OS) and patients over an equal time period prior to the routine use of osteotomy as a reference group (N-OS). Oxford Shoulder Score (OSS) and a Simple Shoulder Test (STT) were used to assess functional outcomes and were compared with the reported literature. Operative times and
Reverse shoulder arthroplasty is becoming a frequent treatment of choice for patients with shoulder disorders. Complication rates after reverse shoulder arthroplasty may be three-fold that of conventional total shoulder arthroplasty especially in high risk patient populations and diagnoses like revision arthroplasty, fracture sequelae, and severe glenoid bone loss.
The aim of this study was to report the incidence of implant-related complications, further operations, and their influence on the outcome in a series of patients who underwent primary reverse total shoulder arthroplasty (RTSA). The prospectively collected clinical and radiological data of 797 patients who underwent 854 primary RTSAs between January 2005 and August 2018 were analyzed. The hypothesis was that the presence of complications would adversely affect the outcome. Further procedures were defined as all necessary operations, including reoperations without change of components, and partial or total revisions. The clinical outcome was evaluated using the absolute and relative Constant Scores (aCS, rCS), the Subjective Shoulder Value (SSV) scores, range of motion, and pain.Aims

Introduction. Two-stage exchange arthroplasty remains the gold standard for treatment of PJI with reported success rates of 85–90%.
Introduction. Prosthetic joint infection (PJI) is an devastating complication after total hip arthroplasty (THA). The common treatment in the US is a two-stage exchange which can be associated with significant morbidity and mortality. The purpose of this study was to analyze complications in the treatment course of patients undergoing two-stage exchange for PJI THA and determine when they occur. Methods. We analyzed all patients that underwent two-stage exchange arthroplasty for treatment of PJI after THA from January 2005 – December 2017 at a single institution.
Aims. Tibial tubercle osteotomy (TTO) facilitates surgical exposure and protects the extensor mechanism during revision total knee arthroplasty (rTKA). The purpose of this study was to determine the rates of bony union, complications, and reoperations following TTO during rTKA, to assess the functional outcomes of rTKA with TTO at two years’ minimum follow-up, and to identify the risk factors of failure. Methods. Between January 2010 and September 2020, 695 rTKAs were performed and data were entered into a prospective database. Inclusion criteria were rTKAs with concomitant TTO, without extensor mechanism allograft, and a minimum of two years’ follow-up. A total of 135 rTKAs were included, with a mean age of 65 years (SD 9.0) and a mean BMI of 29.8 kg/m. 2. (SD 5.7). The most frequent indications for revision were infection (50%; 68/135), aseptic loosening (25%; 34/135), and stiffness (13%; 18/135). Patients had standardized follow-up at six weeks, three months, six months, and annually thereafter.
Specific brace-fitting complications in idiopathic congenital talipes equinovarus (CTEV) have been rarely described in published series, and usually focus on non-compliance. Our primary aim was to compare the rate of persistent pressure sores in patients fitted with Markell boots and Mitchell boots. Our additional aims were to describe the frequency of other brace fitting complications and identify age trends in these complications. A retrospective analysis of medical files of 247 idiopathic CTEV patients born between 01/01/2010 - 01/01/2021 was performed. Data was collected using a REDCap database. Pressure sores of sufficient severity for clinician to recommend time out of brace occurred in 22.9% of Mitchell boot and 12.6% of Markell boot patients (X2 =6.9, p=0.009). The overall rate of bracing complications was 51.4%. 33.2% of parents admitted to bracing non-compliance and 31.2% of patients required re-casting during the bracing period for relapse. For patients with a minimum follow-up of age 6 years, 44.2% required tibialis anterior tendon transfer. Parents admitting to non-compliance were significantly more likely to have a child who required tibialis anterior tendon transfer (X2=5.71, p=0.017). Overall rate of capsular release (posteromedial release or posterior release) was 2.0%. Neither medium nor longterm results of Ponseti treatment in the Australian and New Zealand clubfoot have been published. Globally, few publications describe specific bracing complications in clubfoot, despite this being a notable challenge for clinicians and families. Recurrent pressure sores is a persistent complication with the Mitchell boots for patients in our center. In our population of Australian clubfoot patients, tibialis anterior tendon transfer for relapse is common, consistent with the upper limit of tibialis anterior tendon transfer rates reported globally.
There has recently been an increase in the number of hip replacement procedures performed through an anterior approach. Every procedure has a risk profile, and in the case of a new procedure or technique it is important to investigate the incidence of complications. The aim of this study is to identify the complications encountered in the first 100 patients treated with the minimally invasive anterior approach. This is a case series of the first 100 hips treated and were assessed for complications. These were classified according to the severity and outcome [1]. The 100 hip comprised of 98 patients; 46 males and 52 females with an average operation age on 70.1 (±9.38) years. There were 2 bilateral procedures. Specific patient selection criteria were used. All complications occurred within one month of surgery.
One of the most important sequelae to ageing is osteoporosis and subsequently hip fractures. Hip fractures are associated with major morbidity, mortality and costs. Most patients require surgery to restore mobility. Provision of surgery and its complications is poorly understood in South Africa. Our aim was to collect and report current hip fracture care at four centres in South Africa, as well as reporting surgical and general patient outcomes. A three year retrospective cohort at four centres will be described, focussing on provision of surgical care, mortality, types of surgery and complications. We identified 562 patients who had surgical intervention for fragility fractures, 66% were females. Forty nine percent had open reduction and internal fixation, 28% had hemi-arthroplasty replacement whilst 23% had total hip replacements. Twenty percent of patients had operative intervention within 36 hours of presentation to the emergency department. Mortality was 9% at 30 days. The most common complications were lower respiratory infections (29%), urinary tract infections (21%) and surgical site infections (9%). This is the largest cohort of surgically treated hip fracture from South Africa. Proportions of patients receiving different surgical interventions such as THR are comparable to the broader literature. However a number of key performance indicators such as surgery within 36 hours are challenging to meet. Given the changing demographics of South Africa, this study provides an early insight to contemporary care and may help provide direction for broader national strategies for reporting and improving hip fracture care.
Midfoot arthrodesis is the conventional surgical intervention for midfoot arthritis. Arthrodesis aims to stabilise, realign and fuse the affected joints, providing patients with improved pain and function. Current research neglects the measurement of patient reported outcomes. This study aimed to investigate objective, and patient reported outcomes of midfoot arthrodesis. The secondary aim was to identify variables predicting the development of non-union. An automated search of online patient records identified 108 eligible patients (117 feet). The rates of union, re-operations, and complications were calculated using radiographs and medical records. Logistic regression was used to model variables influencing the odds of non-union. All living patients were posted a Manchester Oxford Foot Questionnaire (MOx-FQ), a patient reported outcome assessment. Pre-operative MOx-FQ results were available in a minority of cases. Students t-test was used to compare pre- and post-operative MOx-FQ scores. The rate of union achieved was 74%. The rate of re-operations was 35%. The rate of complications was 14%. Bone grafts and staple fixation independently impacted the odds of non-union. Bone grafts decreased the odds of non-union, whilst staple fixation increased the odds. This finding agrees with the opinion of other researchers. We recommend the use of bone grafts, and the avoidance of fixation with staples. Previous attempts have been made to assess patient outcomes. However, this study is the first to use the MOx-FQ, a validated questionnaire. Therefore, this study establishes a baseline for improvements in patient reported outcomes.
Surgical options for management of a failed ankle arthroplasty are currently limited; typically conversion to fusion is recommended with only a few patients being considered for revision replacement surgery. This paper presents our experience of revision ankle replacements in a cohort of patients with failed primary replacements. A total of 18 revision TAR in 17 patients were performed in patients with aseptic loosening. The technique was performed by a single surgeon (CSK) over a 4 year period between July 2014 and August 2018 using the Inbone total ankle replacement system. Patient demographics and clinical outcomes were collected retrospectively using - MOXFQ, EQ5D, VAS pain score and patient satisfaction questionnaires.Aim

Aims. There has been an increasing use of early operative fixation for scaphoid fractures, despite uncertain evidence. We conducted a meta-analysis to evaluate up-to-date evidence from randomized controlled trials (RCTs), comparing the effectiveness of the operative and nonoperative treatment of undisplaced and minimally displaced (≤ 2 mm displacement) scaphoid fractures. Methods. A systematic review of seven databases was performed from the dates of their inception until the end of March 2021 to identify eligible RCTs. Reference lists of the included studies were screened. No language restrictions were applied. The primary outcome was the patient-reported outcome measure of wrist function at 12 months after injury. A meta-analysis was performed for function, pain, range of motion, grip strength, and union.
Introduction: The aim of the study is to assess the complication rate in lengthening of the femur and to analyze the main factors inducing complications. Materials &
method: A retrospective study of 151 cases of lengthening with different methods (External Fixator of Judet 9, Callotasy with Orthofix :89, Ilizarov 9, External Fixator of Wagner 9, Lengthening Albizzia Nail 29) was investigated. The mean age was 13, 21 years (ET : 4,82, max : 38, min : 4). The aetiologies of femoral length discrepancy were congenital in 85 cases, post traumatic in 30, Post infectious in 22 and neurologic in 13 cases. One girl had Still’s Disease. The mean elongation was 55,17mm (ET : 17,3, Max ; 130, min : 20) except with the Ilizarov method with a mean lengthening of 91,8 mm. The mean percentage of elongation was 21 %. Classification of the
Diabetes mellitus is a risk factor for complications after operative management of ankle fractures. Generally, diabetic sequelae such as neuropathy and nephropathy portend greater risk; however, the degree of risk resulting from these patient factors is poorly defined. We sought to evaluate the effects of the diabetic sequelae of neuropathy, chronic kidney disease (CKD), and peripheral vascular disease (PVD) on the risk of complications following operative management of ankle fractures. Using a national claims-based database we analyzed patients who had undergone operative management of an ankle fracture and who remained active in the database for at least two years thereafter. Patients were divided into two cohorts, those with a diagnosis of diabetes and those without. Each cohort was further stratified into five groups: neuropathy, CKD, PVD, multiple sequelae, and no sequelae. The multiple sequelae group included patients with more than one of the three sequelae of interest: CKD, PVD and neuropathy. Postoperative complications were queried for two years following surgery. The main complications of interested were: deep vein thrombosis (DVT), surgical site infection, hospital readmission within 90 days, revision internal fixation, conversion to ankle fusion, and below knee amputation (BKA). We identified 210,069 patients who underwent operative ankle fracture treatment; 174,803 had no history of diabetes, and 35,266 were diabetic. The diabetic cohort was subdivided as follows: 7,506 without identified sequelae, 8,994 neuropathy, 4,961 CKD, 1,498 PVD, and 12,307 with multiple sequelae. Compared to non-diabetics, diabetics without sequelae had significantly higher odds of DVT, infection, readmission, revision internal fixation and conversion to ankle fusion (OR range 1.21 – 1.58, p values range Compared to uncomplicated diabetics, diabetics with neuropathy alone and diabetics with multiple sequelae were found to have significantly higher odds of all complications (OR range 1.18 – 31.94, p values range < 0.001 - 0.034). Diabetics with CKD were found to have significantly higher odds of DVT, readmission, and BKA (OR range 1.34 – 4.28, p values range < 0.001 - 0.002). Finally, diabetics with PVD were found to have significantly higher odds of DVT, readmission, conversion to ankle fusion, and BKA (OR range 1.62 - 9.69, p values range < 0.001 - 0.039). Diabetic patients with sequelae of neuropathy, CKD or PVD generally had higher complication rates than diabetic patients without these diagnoses. Unsurprisingly, diabetic patients with multiple sequalae are at the highest risk of complications and had the highest odds ratios of all complications. While neuropathy is known to be associated with postoperative complications, our analysis demonstrates that CKD represents a significant risk factor for multiple complications following the operative management of ankle fractures and has rarely been discussed in prior studies.
A common acute orthopaedic presentation is an ulcerated or infected foot secondary to diabetic neuropathy. Surgical debridement or amputation are often required to manage this complication of diabetes. International literature indicates that amputation may lead to further complications and an increased mortality rate. The aim of this study is to investigate the mortality rate associated with different surgical interventions. This will inform surgical management of patients presenting with acute foot complications from diabetes. This is a retrospective review of patients with diabetic foot infections aged >16 years attending Middlemore Hospital over a 10-year period (2012–2021). Clinical records were examined to determine whether patients were managed with no surgery, surgery but not amputation, or amputation. We recorded relevant baseline characteristics and comorbidities. Regression models were used to determine factors associated with mortality.Introduction

Introduction. Increasingly, patients with bilateral hip arthritis wish to undergo staged total hip arthroplasty. With the rise in demand for arthroplasty perioperative risk assessment and counseling is critical for shared decision making; however, it is unknown if complications that occur after a unilateral hip arthroplasty predict complications following surgery of the contralateral hip. Methods. We used nation-wide linked discharge data from the Hospital Cost and Utilization Project from 2005–2014 to analyze the incidence and recurrence of complications following the first and second stage operations in staged bilateral total hip arthroplasty (BTHAs).
Aims: The knee is the commonest articular location in osteosarcoma (OS). We study the complications in limb salvage due to OS in knee reconstructions. Methods: In our series of 107 OS for the period 1983–1998, limb salvage procedure was possible in 78 cases and the amputation was necessary in 29 patients. The Knee reconstruction includes 62 cases (39 due to femur OS and 23 due to tibia OS). All cases were treated with preoperative and postoperative chemotherapy. The average follow-up was 87.4 months with a range of 55 to 183 months. Results:
Purpose of the study: High quality knee stability and function after unicompartmental reconstruction is a considerable surgical challenge. Occasionally, the healthy compartment has to be sacrificed to achieve prosthetic reconstruction. Osteoarticular reconstructions using allografts enable restoration of the anatomic configuration and reinsertion of the articular structures (menisci) and periarticular ligaments. The purpose of this study was to analyze survival of unicompartmental osteoarticu-lar allografts of the knee and to assess complications. Material and methods: A series of 40 unicompartmental osteoarticular allografts of the knee joint were performed from 1962 to 2001 in 38 patients followed for ten years on average (range 2–35 years). Reconstruction was performed after tumor resection in 36 patients (33 giant-cell tumors, 1 osteogenic sarcoma, 1 chondrosarcoma, 1 malignant fibrohistocytome) and after open fracture in two. The procedure involved a femoral allograft in 29 knees (medial for 11 and lateral for 18), and a tibial graft in 11 (medial for 4 and lateral for 7). Menisci and ligaments were attached to the allograft depending on the configuration of the reconstruction. A rigid screw plate internal fixation was used in all cases. The Kaplan-Meier survival was plotted from implantation to revision or last follow-up.
While obesity is associated with an increased risk of complications after total hip arthroplasty (THA) the relationship between body mass index (BMI) and the risk of early postoperative complications has not been fully characterized. This study sought to describe the relationship between BMI and the risk of early postoperative complications, including periprosthetic joint infection (PJI), composite surgical, and composite medical complications. Primary, elective THAs performed from 2016–2021 were identified using the Premier Healthcare Database (PHD). The study's primary outcome was the diagnosis of PJI within 90 days of THA. Using BMI as a continuous variable, logistic regression was used to develop restricted cubic splines (RCSs) to determine the impact of BMI on PJI risk. Bootstrap simulation was used to identify an inflection point in the final RCS model. The same technique was used to characterize the effects of BMI on composite medical and surgical complications. We found that PJI risk increased exponentially beyond a BMI cutpoint of 37.4 kg/m2. Relative to the cutpoint, patients with a BMI of 40 or 50 kg/m2 were at a 1.22- and 2.55-fold increased risk of developing PJI, respectively. Surgical complications increased at a BMI of 32 kg/m2 and medical complications increased at a BMI of 39 kg/m2. Relative to these cutpoints, patients with a BMI of 50 kg/m2 were at a 1.36- and 2.07-fold increased risk of developing medical and surgical complications, respectively. The results of this study indicate a non-linear relationship between patient BMI and early postoperative risk of PJI, composite medical complications, and composite surgical complications following THA. The identified cutpoints with associated odds ratios can serve as tools to help risk-stratify and counsel patients seeking primary THA.
Paediatric bone and joint infections remain common in low- and middle-income countries (LMICs). We aimed to determine the complication rate and incidence of disseminated infection in paediatric bone and joint infections in an LMIC setting. Secondly, we aimed to elucidate factors associated with complications and disseminated disease. We retrospectively reviewed our database for children that presented with bone and joint infections between September 2015 and March 2019. Data were extracted to identify factors that were associated with development of complications and disseminated infection. We analysed 49 children. The median age at presentation was 6 years (range 1 month to 12 years). Locally advanced disease was present in 13 children (27%). The remaining 36 children were evenly divided (18/49 each, 37%) between isolated AHOM and SA, respectively. Disseminated disease was present in 16 children (33%) and was associated with locally advanced disease, an increase in number of surgeries and an increased length of stay. Twenty-six complications were documented in 22 (45%) children. Chronic osteomyelitis developed in 15/49 (31%) cases, growth arrest in 5/49 (10%), and pathological fracture, DVT and septic shock in 2/49 (4%) each. Complicated disease was associated with locally advanced disease, a higher number of surgeries, disseminated disease and an increased length of stay. Sixty five percent of cases cultured Staphylococcus aureus, while 25% (12/49) were culture negative. The median time from admission to surgery was one day, and the median time from onset of symptoms to surgery was seven days. We found a high complication rate. One third of patients had locally advanced disease, and this was associated with the development of complications and disseminated disease. Further studies are needed to be able to predict which children will have poor outcomes.
Cheilectomy is a recommended procedure for the earlier stages of osteoarthritis of the 1st metatarsophalangeal joint. Although good improvement in symptoms have been reported in many studies, the long term performance of this procedure is not well understood. It is thought that a significant number of patients go onto have arthrodesis or joint replacement. We report on a large cohort of patients who received this procedure and report on the complications and mid-term outcome. This is a retrospective study looking at all patients who underwent cheilectomy for hallux rigidus between November 2007 and August 2018. Departmental database was used to access patient details and outcome measures recorded include: postoperative wound infection, patient reported improvement in pain and the incidence of further surgical interventions like revision cheilectomy and conversion to arthrodesis and arthroplasty. X-rays were studied using PACS to stage the osteoarthritis (Hattrup and Johnson classification).Introduction
Methods
Surgeons must explain the risk of complications to prospective patients and get informed consent. If a complication that occurred was omitted in the process or given the wrong risk level, culpability of the surgeon is judged in court against what a “reasonable patient” would like to know to give or refuse consent. ObjectivesThe concept “reasonable patient” is widely used, no attempt has been made to define it objectively. We assessed insight of patients, presumed “reasonable”, about risks of certain complications after they underwent one of five orthopaedic procedures. Questionnaire was administered with procedures: femur IMN, tibia IMN, ankle ORIF, distal radius ORIF and hip arthroplasty. Four common/serious complications were chosen per procedure, and matched against life events with documented risk levels. There were 230 participants 163 males and 67 females. We found 19.1% of patients above age 40 and 33.3% with tertiary education wouldn't accept nerve injury as reported in literature. With infection risk, 18.1% above 40 and 52.9% with pre-tertiary education would not accept. All patients below 40 and 7.4% pre-tertiary education wouldn't accept the risk of death as reported. However, 37.1% above 40 and 76.9% with pre-tertiary education would accept that risk at a higher level. It is hard to predict what risk of complication a patient may accept. This study highlights that some patients will not accept risks as reported in literature, even though they need the procedure. Therefore, surgeons need to explain complications fully, so that patients knowingly accepts or refuses consent. The subset of patients who are not willing to accept any level of risk, should be the subject of another study.
There has recently been an increase in the number of hip replacement procedures performed through an anterior approach. Every procedure has a risk profile, and in the case of a new procedure or technique it is important to investigate the incidence of complications. The aim of this study is to identify the complications encountered in the first 100 patients treated with the minimally invasive anterior approach. This is a case series of the first 100 hips treated and were assessed for complications. These were classified according to the severity and outcome [1]. The 100 hip comprised of 98 patients; 46 males and 52 females with an average operation age on 70.1 (±9.38) years. There were 2 bilateral procedures. Specific patient selection criteria were used. All complications occurred within one month of surgery.
Arthrodesis of the 1st metatarsophalangeal joint (MTPJ) is a common procedure used for the treatment of end stage arthritis. We studied a cohort of patients who underwent an isolated 1st MTPJ Fusion for the treatment of hallux rigidus. Here we report the 10-year clinical outcomes, complication rate, requirement for further surgery and patient experience. All patients, who underwent an isolated 1st MTPJ Fusion for osteoarthritis from June 2008 until November 2011 were included. Demographics, clinical outcome data and subsequent procedures performed were collected from a departmental database (Bluespier). Patients were contacted and asked to complete the MOxFQ questionnaire and rate their satisfaction using pain, function and if they would undergo the surgery again. Mean follow up was 10.85 (range 9–12) years. A total of 161 patients (183 feet) underwent an isolated 1st MTPJ fusion during this time period. 156 of the feet showed a successful arthrodesis (85.2% fusion rate); 27 patients required revision surgery, 19 (10.4%) for a symptomatic non-union and 8 (4.4%) for mal-union. Those patients with co-morbidities (diabetes and gout) required revision earlier than those without (p<0.01). Average MOxFQ score was 16.6 (0–64) and 28 out of the 38 (73.6%) said they would have the operation again. Overall, the long-term results of the 1st MTPJ fusion had good outcomes with a successful fusion rate and minimal complications, both in line with the corresponding literature. In this series, fusion provided high patient satisfaction with the majority of patients opting to undergo fusion with the gift of hindsight.
The purpose of this study was to analyse the complications of THAs in CDH. 418 THAs were performed in 356 patients, with a mean follow-up 108 (7–237) months. The mean age was 53.3 (24–79) years. 83 patients had CDH in high position. 40 stems were custom made.
The primary objective is to compare revision rates for lumbar disc replacement (LDR) and fusion at the same or adjacent levels in Ontario, Canada. The secondary objectives include acute complications during hospitalization and in 30 days, and length of hospital stay. A population-based cohort study was conducted using health administrative databases including patients undergoing LDR or single level fusion between October 2005 to March 2018. Patients receiving LDR or fusion were identified using physician claims recorded in the Ontario Health Insurance Program database. Additional details of surgical procedure were obtained from the Canadian Institute for Health Information hospital discharge abstract. Primary outcome measured was presence of revision surgery in the lumbar spine defined as operation greater than 30 days from index procedure. Secondary outcomes were immediate/ acute complications within the first 30 days of index operation. A total of 42,024 patients were included. Mean follow up in the LDR and fusion groups were 2943 and 2301 days, respectively. The rates of revision surgery at the same or adjacent levels were 4.7% in the LDR group and 11.1% in the fusion group (P=.003). Multivariate analysis identified risk factors for revision surgery as being female, hypertension, and lower surgeon volume. More patients in the fusion group had dural tears (p<.001), while the LDR group had more “other” complications (p=.037). The LDR group had a longer mean hospital stay (p=.018). In this study population, the LDR group had lower rates of revision compared to the fusion group. Caution is needed in concluding its significance due to lack of clinical variables and possible differences in indications between LDR and posterior decompression and fusion.
The surgical management of late PJI was usually done in two stages with the placement of a temporary cement spacer. The development of one-stage surgical care raises questions about the two-stage strategy. The objectives of this study are to identify the complications related to the presence of the cement spacer within a two-stage strategy. The septic recurrence rate is also evaluated after a minimum follow-up of two years. Medical files of 208 patients (101 knees and 107 hips) who underwent a two-stage revision for late PJI prosthesis infection were retrospectively reviewed. Antibiotic loaded articulated homemade cement spacers were used. Second stage was usually planned on average 4 to 6 weeks after the first stage. Patients were allowed to walk without loading. The success rate was defined as the absence of septic recurrence after a minimum follow-up of two years. Descriptive statistics and uni- and multivariate analysis were conducted.Introduction
Material and methods
Background. To evaluate the causes and modes of complications after unicompartmental knee arthroplasty (UKA), and to identify its prevention and treatment method by analyzing the complications after UKA. Materials and Methods. A total of 1,576 UKAs were performed between January 2002 and December 2014 at a single-institution. Postoperative complications occurred in 89 knees (83 patients, 5.6%), and 86 of them were found in females and 3 in males. Their mean age was 61 years (range, 46 to 81 years) at the time of initial UKA and 66 years (range, 46 to 82 years) at the time of revision surgery. We analyzed the complications after UKA retrospectively andinvestigated the proper methods of treatment (Table 1). Results. A total of 89 complications (5.6%) occurred afterUKA. Regarding the type of complications after UKA, there were bearing dislocation (n=42), component loosening (n=23), 11 cases of femoral component loosening, 8 cases of tibial component loosening, and 4 cases of both femoral and tibial component loosening, periprosthetic fracture (n=6), polyethylene wear/ destruction (n=3), progression of arthritis to the other compartment (n=3), medial collateral ligament (MCL) injury (n=2), impingement (n=2), infection (n=5), ankylosis (n=1), and unexplained pain (n=2) (Table 2). The most common complication after UKA was mobile bearing dislocation in mobile-bearing type and loosening of prosthesis in fixed-bearing type, but polyethylene wear and progression of arthritis were relatively rare. The mean interval from UKA to the occurrence of complications was 4 years and 6 months (range, 0 [during operation] to 12 years). Of those complications following UKA, 58 knees were treated with conversion TKA, 1 with revision UKA, and 21 with simple bearing change.
The incidence of reverse total shoulder replacement (rTSR) implantation is increasing globally, but apprehension exists regarding complications and associated challenges. We retrospectively analysed the senior author's series of rTSR from a tertiary centre using the VAIOS shoulder system, a modular 4th generation implant. We hypothesised that the revision rTSR cohort would have less favourable outcomes and more complications. 114 patients underwent rTSR with the VAIOS system, over 7 years. The primary outcome was implant survival. Secondary outcomes were Oxford shoulder scores (OSS), radiographic analysis (scapular notching, tuberosity osteolysis, and periprosthetic radiolucent lines) and complications.Abstract

Cheilectomy is a recommended procedure for early stage osteoarthritis of the 1st metatarsophalangeal joint. Although improvement in symptoms has been reported in many studies, long term performance is not well understood. It is thought that significant numbers of patients require subsequent arthrodesis or arthroplasty. We report on a large cohort of patients receiving this procedure and on complications, and mid-term outcome. This is a retrospective study looking at all patients undergoing cheilectomy for hallux rigidus between November 2007 and August 2018. Departmental database was used to record outcome measures including: postoperative wound infection, patient reported improvement in pain and incidence of further surgical interventions like revision cheilectomy, conversion to arthrodesis and arthroplasty. Osteoarthritis was staged radiographically using PACS (Hattrup and Johnson classification). A total of 240 feet in 220 patients (20 bilateral surgeries) were included with 164 females (75%) and 56 males (25%), the median age being 55 years (range 22–90 years). Radiological assessment showed 89 stage 1 arthritis (42%), 105 stage 2 (50%), 17 stage 3 (8%) and 9 patients were excluded due to unavailable radiographs. 5 patients (2%) had superficial wound infections. There were 16 further surgeries (7%); 12 arthrodesis (5%), 3 revision cheilectomy and 1 conversion to arthroplasty. 157 patients were found to be pain-free at the latest post-operative visit (77%), 48 reported minimal pain (23%), 15 patients were excluded due to incomplete data. Cheilectomy appears to effectively reduce pain with low complication rates. Rates of conversion to arthrodesis/arthroplasty are lower than in many reported studies.
Introduction. Although we know that smoking damages health, we do not know impact of smoking on a patient's outcome following primary knee arthroplasty (KA). In the UK, clinical commissioning groups (CCGs) have the authority (& funds) to commission healthcare services for their communities. Over the past decade, an increasing number of CCGs are using smoking as a contraindication for patients with end-stage symptomatic knee arthritis being referred to a specialist for due consideration of KA without any clear evidence of the associated risks & benefits. The overall objective of this study is to compare clinical outcomes after knee arthroplasty surgery in smokers, ex-smokers & non-smokers. Methods. We obtained data from the UK Clinical Research Practice Datalink (CPRD) that contains information on over 11 million patients (7% of the UK population) registered at over 600 general practices. CPRD data was linked to Hospital Episode Statistics, hospital admissions & Patient Reported Outcome Measures (PROMs) data. We collected data on all KAs (n=64,071) performed over a 21-year period (1995 to 2016). Outcomes assessed included: local & systemic complications (at 6-months post-surgery): infections (wound, respiratory, urinary), heart attack, stroke & transient ischaemic attack, venous thromboembolism, hospital readmissions & GP visits (1-year), analgesic use (1-year), surgical revision (up to 20-years), mortality (90-days and 1-year), & 6-month change from pre-operative scores in Oxford Knee Score (OKS). Regression modelling is used to describe the association of smoking on outcomes, adjusting for confounding factors. Results. Smoking was associated with an increased risk of lower respiratory tract infections (LRTI) (4.2% smokers vs. 2.7% non-smokers) (Odds Ratio (OR) 0.76, p-value 0.017). LRTI were similar in ex-smokers & smokers at 3.9%. There was no association with any of the other 6-month complications. Pain medication use over 1-year post surgery was higher in smokers compared to non-smokers: gabapentinoids 7.4% vs. 5.2% (OR 0.74, p< 0.001), opioids 45.9% vs. 35.3% (OR 0.79, p< 0.001), NSAIDs 51.6% vs. 46.1% (OR 0.91, p = 0.044). Mortality was higher in smokers at 1-year compared to non-smokers (hazard ratio (HR) 0.53, p<0.001) & ex-smokers (HR 0.65, p = 0.037), but there was no difference observed at 90-days. There was no association of smoking on revision surgery over 20-years follow up. Smoking was associated with worse postoperative OKS being 3.1 points higher in non-smokers (p<0.001) & 3.0 points higher in ex-smokers (p<0.001). The overall change in OKS before & after surgery was 13.9 points in smokers versus 16.3 points in non-smokers (p<0.001) & 15.7 points in ex-smokers (p<0.001). Over the year following surgery, smokers were more likely to visit their GP, but there was no association with hospital readmission rates. Conclusion. This is the largest study with linked primary care & secondary care data highlighting impact of a preventable patient factor on outcome of a routinely performed planned intervention. Smokers achieved clinical meaningful improvements in patient reported pain & function (OKS) following KA, although their attained post-operative OKS was lower than in non-smokers & ex-smokers. Levels of pain medication use were notably higher in both smokers & ex-smokers. As smokers achieved good clinical outcomes following KA surgery, smoking should not be a barrier to referral for or consideration of KA. However, the study does highlight particular risks a patient is taking if he/she continues to smoke when being considered for elective knee arthroplasty. This study will help the family physicians as well as patients to make an informed decision on whether to go ahead with a planned intervention whilst patient continues to be an active smoker or not.

AIM. To present our experience in patients treated under primary diagnosis giant cell tumor of bone at Department Orthopaedic Surgery Zagreb University School of Medicine in a 15-year period from 1995 to 2009. METHODS. We performed a retrospective study of all patients treated in our Department because of giant cell tumor of bone (GCT) from 1995 to 2009. The mean age of our patients was 29,9 years (range: 14 to 70 years). Sex distribution showed prevalence in female (F:M=23:12=66%:34%). All together, 39 patients were operated under primary diagnosis of GCT. Four patients were lost in follow-up. In total, 35 patients were included in study. Diagnosis of GCT was made according to clinical, imaging and histological findings, and distributed by Campanacci's classification. RESULTS. Not including diagnostic biopsy, 84 operations were performed on 35 patients. Fourteen patients (40%) had GCT grade 1, fourteen (40%) had GCT grade 2, and seven (20%) had GCT grade 3. From the first symptoms to diagnosis there was an average duration of 7 months (range: 0 to 24 months), where the main symptoms were pain and swelling of affected bone and/or joint. GCT was localized in distal femur (n=12, 34%), proximal tibia (n=10, 29%), distal tibia (n=4, 11%), distal radius (n=3, 9%), and other locations (n=6, 17%). Patients with less aggressive GCT (grades 1 and 2) were treated with marginal excision: excochleation and reconstruction with bone transplant (n=12, 34%). In patients with locally more aggressive tumor (grades 2 and 3), “en bloc” resection and reconstruction with tumor endoprosthesis or bone transplant was performed (n=22, 63%). Due to localization of tumor, one patient was treated with radiation (3%).
Atypical femur fracture (AFF) is a well known complication of Bisphosphonate therapy. Due to prolonged suppression of bone re-modelling in these fractures, surgical complications are difficult to manage. The aim of this study was to analyze the causes of surgical complications in AFF fixations and provide algorithm for management. In this retrospective 10-year study (2010–2020), we identified patients surgically treated for AFF. We included patients who underwent revision surgery for any cause. Data collection included demographics, surgical complications, details of revision surgery and time to union.Abstract

Total hip arthroplasty (THA) in neglected congenital dislocation of the hip (CDH) constitutes a challenging procedure, with surgical difficulties and complications. The purpose of this study was to analyse the complications of THAs in CDH. Between June 1983 and September 2002, 418 THAs-were performed in 356 patients with CDH, with a mean follow-up 108 (7–237)months. The mean age at surgery was 53.3 (24–79) years with 325 females and31 males. 83 patients had CDH in high position. 307 arthroplasties were cementless, 39 cemented and 72 hybrids. 40 stems were custom made. The cup always was positioned at the true acetabulum. 24 shortening osteotomies of the femur, 8 corrective supracondylar and 6 trochanteric osteotomies were performed. Preoperatively the average Merle d’Aubigne-Postel hip score was 1.1 for pain, 4.8 for range of motion and 3.1 for walking ability. Postoperatively the average hip score was 5.2, 4.7 and 5.3 respectively. The average length discrepancy was 8 cm (3–12) preoperatively and 1.5 cm remained in 8 patients.
Circular frames for ankle fusion are usually reserved for complex clinical scenarios. Current literature is heterogenous and difficult to interpret. We aimed to study the indications and outcomes of this procedure in detail. A retrospective cohort study was performed based on a prospective database of frame surgeries performed in a tertiary institution. Inclusion criteria were patients undergoing complex ankle fusion with circular frames between 2005 and 2020, with a minimum 12-month follow up. Data were collected on patient demographics, surgical indications, comorbidities, surgical procedures, external fixator time (EFT), length of stay (LOS), radiological and clinical outcomes, and adverse events. Factors influencing radiological and clinical outcomes were analysed.Introduction
Materials & Methods
Total hip arthroplasty (THA) is performed under general anesthesia (GA) or spinal anesthesia (SA). The first objective of this study was to determine which patient factors are associated with receiving SA versus GA. The second objective was to discern the effect of anesthesia type on short-term postoperative complications and readmission. The third objective was to elucidate factors that impact the effect of anesthesia type on outcome following arthroplasty. This retrospective cohort study included 108,905 patients (median age, 66 years; IQR 60-73 years; 56.0% females) who underwent primary THA for treatment of primary osteoarthritis in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database during the period of 2013-2018. Multivariable logistic regression analysis was performed to evaluate variables associated with anesthesia type and outcomes following arthroplasty. Anesthesia type administered during THA was significantly associated with race. Specifically, Black and Hispanic patients were less likely to receive SA compared to White patients (White: OR 1.00; Black: OR 0.73; 95% confidence interval [CI] 0.71-0.75; Hispanic: OR 0.81; CI, 0.75-0.88), while Asian patients were more likely to receive SA (OR 1.44, CI 1.31-1.59). Spinal anesthesia was associated with increased age (OR 1.01; CI 1.00-1.01). Patients with less frailty and lower comorbidity were more likely to receive SA based on the modified frailty index ([mFI-5]=0: OR 1.00; mFI-5=1: OR 0.90, CI 0.88-0.93; mFI-5=2 or greater: OR 0.86, CI 0.83-0.90) and American Society of Anesthesiologists (ASA) class (ASA=1: OR 1.00; ASA=2: OR 0.85, CI 0.79-0.91; ASA=3: OR 0.64, CI 0.59-0.69; ASA=4-5: OR 0.47; CI 0.41-0.53). With increased BMI, patients were less likely to be treated with SA (OR 0.99; CI 0.98-0.99). Patients treated with SA had less post-operative complications than GA (OR 0.74; CI 0.67-0.81) and a lower risk of readmission than GA (OR 0.88; CI 0.82-0.95) following THA. Race, age, BMI, and ASA class were found to affect the impact of anesthesia type on post-operative complications. Stratified analysis demonstrated that the reduced risk of complications following arthroplasty noted in patients treated with SA compared to GA was more pronounced in Black, Asian, and Hispanic patients compared to White patients. Furthermore, the positive effect of SA compared to GA was stronger in patients who had reduced age, elevated BMI, and lower ASA class. Among patients undergoing THA for management of primary osteoarthritis, factors including race, BMI, and frailty appear to have impacted the type of anesthesia received. Patients treated with SA had a significantly lower risk of readmission to hospital and adverse events within 30 days of surgery compared to those treated with GA. Furthermore, the positive effect on outcome afforded by SA was different between patients depending on race, age, BMI, and ASA class. These findings may help to guide selection of anesthesia type in subpopulations of patients undergoing primary THA.
In reverse shoulder arthroplasty (RSA), a high complication rate is noted in the international literature (24.7%), and limited local literature is available. The complications in our developing health system, with high HIV, tuberculosis and metabolic syndrome prevalence may be different from that in developed health systems where the literature largely emanates from. The aim of this study is to describe the complications and complication rate following RSA in a South African cohort. An analytical, cross-sectional study was done where all patients’ who received RSA over an 11 year period at a tertiary hospital were evaluated. One-hundred-and-twenty-six primary RSA patients met the inclusion criteria and a detailed retrospective evaluation of their demographics, clinical variables and complication associated with their shoulder arthroplasty were assessed. All fracture, revision and tumour resection arthroplasties were excluded, and a minimum of 6 months follow up was required. A primary RSA complication rate of 19.0% (24/126) was noted, with the most complications occurring after 90 days at 54.2% (13/24). Instability was the predominant delayed complication at 61.5% (8/13) and sepsis being the most common in the early days at 45.5% (5/11). Haematoma formation, hardware failure and axillary nerve injury were also noted at 4.2% each (1/24). Keeping in mind the immense difference in socioeconomical status and patient demographics in a third world country the RSA complication rate in this study correlates with the known international consensus. This also proves that RSA is still a suitable option for rotator cuff arthropathy and glenohumeral osteoarthritis even in an economically constrained environment like South Africa.
The purpose of this study was to report all complications during the first consecutive 865 cases of bikini incision direct anterior approach (DAA) total hip arthroplasty (THA) performed by a single surgeon. The secondary aims of the study are to report our clinical outcomes and implant survivorship. We discuss our surgical technique to minimize complication rates during the procedure. We undertook a retrospective analysis of our complications, clinical outcomes and implant survivorship of 865 DAA THA's over a period of 6 years (mean = 5.1yrs from 2.9 to 9.4 years). The complication rates identified in this study were low. Medium term survival at minimum 2-year survival and revision as the end point, was 99.53% and 99.84% for the stem and acetabular components respectively. Womac score improved from 49 (range 40-58) preoperatively to 3.5(range 0-8.8) and similarly, HHS scores improved from 53(range 40-56) to 92.5(range 63-100) at final follow-up (mean = 5.1 yrs) when compared to preoperative scores. These results suggest that bikini incision DAA technique can be safely utilised to perform THA.
Purpose:. We aimed to assess the short and medium term complications of patients who had undergone Latarjet procedures. We also compared this to a group of patients who over a similar period underwent an open Bankhart procedure to assess the complication profiles between the two groups. Method:. We retrospectively reviewed the notes and X-rays of all patients identified by surgical log books and or operation codes for instability. Eighty seven patients (88 shoulders) underwent Latarjet procedures between 2002 and 2010. Patients were phoned to obtain a telephonic Oxford shoulder score. There were 44 patients with 46 shoulders in the open Bankhart group. Results:.
Swelling following an ankle fracture is commonly believed to preclude surgical fixation, delaying operative treatment to allow the swelling to subside. This is in an attempt to achieve better soft tissue outcomes. We aim to identify whether pre-operative ankle swelling influences postoperative wound complications following ankle fracture surgery. This is a prospective cohort study of 80 patients presenting to a tertiary referral centre with operatively managed malleolar ankle fractures. Ankle swelling was measured visually and then quantitatively using the validated ‘Figure-of-eight’ technique. Follow-up was standardised at 2, 6, and 12 weeks post-operatively. Wound complications, patient co-morbidities, operative time, surgeon experience, and hospital stay duration were recorded. The complication rate was 8.75% ( Increasing age ( Visual assessment of ankle swelling had a poor to moderate correlation to ‘Figure-of-eight’ ankle swelling measurements Neither ankle swelling nor time to surgery correlates with an increased risk of postoperative wound complication in surgically treated malleolar ankle fractures. Increasing patient age and female gender had a significantly greater probability of wound infection, irrespective of swelling. Visual assessment of ankle swelling is unreliable for quantifying true ankle swelling. Operative intervention at any time after an ankle fracture, irrespective of swelling, is safe and showed no better or worse soft tissue outcomes than those delayed for swelling.
Tourniquet is a commonly used tool in orthopaedic practice. Incidence of complications is low but if any develops, it is devastating. Transient nerve damage, ischemia or skin burns are the possible tourniquet related complications. There is big variation in practice regarding the limb occlusion pressure. 51 procedures in 50 patients were reviewed retrospectively in our district general hospital. We looked at quality of documentation guided by the BOAST standard (The Safe Use of Intraoperative Tourniquets, published in October 2021). Limb occlusion pressure and ischemic time were analysed. Intra-operative and post-operative notes were reviewed to assess quality of documentation and post-operative complications. Although limb occlusion pressure was above the recommended range in more than 75% of cases, there were no significant complications observed. Two cases only developed transient neuropraxia in common peroneal nerve and median nerve following tibial plateau ORIF and trapeziectomy simultaneously. Tibial ORIF fixation case had prolonged ischemic time (more than 120 minutes) and the limb occlusion pressure for the hand case was above the recommended range. Both have recovered within few days with no long-term consequences. Minimum documentation threshold was not met with regarding tourniquet site condition, method of skin isolation and padding, and exsanguination method. This relatively new standard with no previous similar guidance needs time until it is followed by the health care professionals especially when there is no high incidence of complications related to the use of the tourniquet. However, it is crucial to increase the theatre staff awareness of such standards. This will prevent devastating complications specifically in vulnerable patients. Adjustments to theatre checklist have been suggested to improved documentation. Additionally, local teaching sessions will be delivered to theatre personnel aiming at improving our compliance to this standard.
Purpose of the study: Coxofemoral conflicts can sometimes lead to early degenerative disease in young patients. Hip arthroscopy is a less invasive alternative which can remove all of the coxofemoral conflicts. Like open surgery, a purely arthroscopic technique enables all the necessary corrections, even involving the rim. Arthroscopy has provides promising short- and mid-term results. The purpose of this work was to present the surgical technique, its drawbacks and complications, and present suggestions for improvement. Material and methods: Fifty-one patients, mean age 31 years (range 15–54 years) underwent purely arthroscopic treatment of coxofemoral conflicts between February 2001 and November 2003. Prospective follow-up was at least six months. The type of conflict and the corresponding corrections were noted. The Pre- and postoperative WOMAC scores were used for clinical assessment.
End-stage arthropathy is a well-known complication of haemophilia, with recurrent haemarthroses leading to joint destruction, deformity, pain, and stiffness. In the knee, this is often treated with total knee arthroplasty (TKA), which can be more challenging in patients with haemophilia (PwH) and associated with poorer outcomes. We conducted a systematic literature review and meta-analysis to determine implant survivorship, functional outcomes and complication rates. A systematic review was conducted using MEDLINE, EMBASE, and PubMed for studies reporting TKA outcomes with Kaplan-Meier survivorship in PwH (PROSPERO registered). Meta-analysis was performed for survivorship and outcomes, and the results were compared to outcomes from the National Joint Registry (NJR).Abstract

Although arthroscopy of the hip is being carried out increasingly, little is known about the rate of associated complications. We describe a prospective study of 640 consecutive procedures in which a consistent technique was used. The overall complication rate was 1.6%.
Aim: An epidemiological analysis of spontaneous community acquired septic arthritis cases in an elderly population at a university teaching hospital. Method: We studied confirmed cases of spontaneous septic arthritis in the over 65 population. Patients with prosthetic joint infections were excluded from the study. We analysed data relating to initial presenting complaint and clinical examination, haematological and microbio-logical tests along with ultimate patient outcome. Results: There were 7 confirmed cases of spontaneous septic arthritis in over 65 population in the last 6 months (2 hips, 5 knees). The mean age was 72.14 (range 65–82) with a mean length of stay of 49 days. Those with septic arthritis of the knee presented with swelling, pain and immobility. Hip cases presented with pain and immobility. All patients were systemically well at time of presentation, with no other foci of infection detected after septic screening. All patients had aspirate and arthroscopic/arthrotomy confirmed infection. Staphylococcus Aureus was isolated from 6 joint aspirations and Pseaudomonas Auruginosa from one patient.

Introduction. Dual modular femoral stems for total hip arthroplasty were initially introduced to optimize joint biomechanics. These implants have been recalled due to fretting and crevice corrosion at the stem-neck interface, ultimately necessitating revision in a significant number of patients. At our institution we had experience with the Rejuvenate (Stryker, Mahwah, NJ) dual modular stem from 2009 until 2011 before it's recall in 2012. This study identifies complications encountered in patients requiring revision of this prosthesis. Methods. We retrospectively identified all patients who had one particular dual modular stem using our registry database. All patients’ charts and imaging was reviewed using our electronic medical records and digital imaging programs. Patients’ age, gender, revision date, intraoperative and postoperative complications, need for subsequent surgery were identified. Results. 118 femoral stems were implanted in 107 patients (61 male & 46 female) with average follow up of over 3 years. 40 stems (34%) were revised in 36 patients with an average time to revision of 2.7 years. Women had a revision rate of 42% versus 28% in men for an odds ratio of 1.5.
Total hip arthroplasty (THA) in neglected congenital dislocation of the hip (CDH) constitutes a challenging procedure, with surgical difficulties and complications. The purpose of this study was to analyse the complications of THAs in CDH. Between June 1983 and September 2002, 418 THAs were performed in 356 patients with CDH, with a mean follow-up 108 (7–237) months. The mean age at surgery was 53.3 (24–79) years with 325 females and 31 males. 83 patients had CDH in high position. 307 arthroplasties were cementless, 39 cemented and 72 hybrids. 40 stems were custom made. The cup always was positioned at the true acetabulum. 24 shortening osteotomies of the femur, 8 corrective supracondylar and 6 trochanteric osteotomies were performed. Preoperatively the average Merle d’Aubigne-Postel hip score was 1.1 for pain, 4.8 for range of motion and 3.1 for walking ability. Postoperatively the average hip score was 5.2, 4.7 and 5.3 respectively. The average length discrepancy was 8 cm (3–12) preoperatively and 1.5 cm remained in 8 patients.
With the advent of locked volar radial plates there has been a wave of enthusiasm in the fixation of distal radial fractures with these devices. This study was designed to look at potential complications and pitfalls of this treatment modality. 80 consecutive cases treated by the author with locked volar radial plates were analysed.
A significant number of patients undergoing shoulder arthroplasty surgery have Prospective study including all patients who underwent a reverse shoulder prosthesis from January 2015 to December 2018. In all of them, 5 to 12 cultures were performed during primary surgery. The patients underwent surgery for shoulder arthritis secondary to rotator cuff tears, acute fracture of the proximal humerus, and sequelae of fracture of the proximal humerus. Exclusion criteria included the existence of previous surgeries on the affected shoulder, the presence of signs of infection, having received infiltrations and / or complementary invasive examinations (Arthro-MRI and Arthro-CT). Follow-up from 2 to 5 years. Functional assessment according to the Constant Functional Scale. All complications were also recorded.Aim

Direct oral anticoagulant (DOAC) use is becoming more widespread in the geriatric population. Depending on the type of DOAC, several days are required for its anticoagulant effects to resorb, which may lead to surgical delays. This can have an important impact on hip fracture patients who require surgery. The goal of the current study is to compare surgical delays, mortality and complications for hip fracture patients who were on a DOAC to those who were not. A retrospective cohort study was conducted at a university hospital in Sherbrooke. All hip fracture patients between 2012 and 2018 who were on a DOAC prior to their surgery were included. These patients were matched with similar patients who were not on an anticoagulant (non-DOAC) for age, sex, type of fracture and date of operation. Demographic and clinical data were collected for all patients. Surgical delay was defined as time of admission to time of surgery. Mortality and complications up to one year postoperative were also noted. Each cohort comprised of 74 patients. There were no statistically signification differences in Charleson Comorbidty Index and American Society of Anesthesiologists scores between cohorts. Surgical delay was significantly longer for DOAC patients (36.3±22.2 hours vs. 18.6±18.9 hours, p < 0 .001). Mortality (6.1%) and overall complication (33.8%) rates were similar between the two cohorts. However, there were more surgical reinterventions in DOAC patients than non-DOAC ones (16.2% vs. 0.0%, p < 0 .001). Among DOAC patients, mortality was greater for those operated after 48 hours (23.1% vs. 3.3%, p < 0 .05) and complications were more frequent for those operated after 24 hours (52.0% vs. 37.5%, p < 0 .05). Direct oral anticoagulant (DOAC) use in hip fracture patients is associated with longer surgical delays. Longer delays to surgery are associated with higher mortality and complication rates in hip fracture patients taking a DOAC. Hip fracture patients should have their surgery performed as soon as medically possible, regardless of anticoagulant use.
Direct oral anticoagulant (DOAC) use is becoming more widespread in the geriatric population. Depending on the type of DOAC, several days are required for its anticoagulant effects to resorb, which may lead to surgical delays. This can have an important impact on hip fracture patients who require surgery. The goal of the current study is to compare surgical delays, mortality and complications for hip fracture patients who were on a DOAC to those who were not. A retrospective cohort study was conducted at a university hospital in Sherbrooke. All hip fracture patients between 2012 and 2018 who were on a DOAC prior to their surgery were included. These patients were matched with similar patients who were not on an anticoagulant (non-DOAC) for age, sex, type of fracture and date of operation. Demographic and clinical data were collected for all patients. Surgical delay was defined as time of admission to time of surgery. Mortality and complications up to one year postoperative were also noted. Each cohort comprised of 74 patients. There were no statistically signification differences in Charleson Comorbidty Index and American Society of Anesthesiologists scores between cohorts. Surgical delay was significantly longer for DOAC patients (36.3±22.2 hours vs. 18.6±18.9 hours, p < 0 .001). Mortality (6.1%) and overall complication (33.8%) rates were similar between the two cohorts. However, there were more surgical reinterventions in DOAC patients than non-DOAC ones (16.2% vs. 0.0%, p < 0 .001). Among DOAC patients, mortality was greater for those operated after 48 hours (23.1% vs. 3.3%, p < 0 .05) and complications were more frequent for those operated after 24 hours (52.0% vs. 37.5%, p < 0 .05). Direct oral anticoagulant (DOAC) use in hip fracture patients is associated with longer surgical delays. Longer delays to surgery are associated with higher mortality and complication rates in hip fracture patients taking a DOAC. Hip fracture patients should have their surgery performed as soon as medically possible, regardless of anticoagulant use.

We sought to determine the incidence of complications and re-operation up to one year following primary total knee replacement in a single health region. The Trent Arthroplasty Audit group collects prospective data on all knee replacements performed within this health region (population 5.2 million). All patients are sent a validated, self-administered questionnaire one year after surgery. The questionnaire addresses patient satisfaction and any complications and re-operations following surgery. We analysed the returned questionnaires of 5352 patients [5896 knees] who had their primary knee arthroplasty between 1998 to 2000. Responses were received from 4169 patients [4592 knees] (response rate 80%). Clinical records were also examined to gain further information. 516 patients reported complications in 546 knees. Complication rate of (12%) and 3.5% had a further operation on the joint within one year.
The purpose of this study is to determine the re-operation rate following plate fixation of the olecranon with contoured anatomic plates. Plate fixation of the olecranon allows for management of different fracture patterns as well as osteotomies with anatomic reduction and stable fixation for early elbow mobilization. However, olecranon hardware prominence can be troublesome. Our hypothesis was with the newer generation of low profile contoured anatomic plates, the rate of hardware removal should be lower compared to previously described literature. Retrospective review for patients treated with operative fixation of the olecranon between 2010 and 2015 in the Edmonton zone was identified using population level administrative data. Radiographic screening of these patients was then carried out to identify those who received plate fixation. Fracture patterns were also characterized. Chart reviews followed to determine the indications for re-operation and other post-operative complications. Main outcome measures were re-operation rate and their indications, including hardware prominence. During the screening process, 600 surgically treated olecranon patients were identified and 321 patients were found to have plate fixation of the olecranon. Chart review determined 90 patients had re-operations demonstrating a 28% re-operation rate. Re-operation due to hardware prominence was found to be 15.6%. Other indications included hardware failure (5.3%), infection (2.8%), or contracture (2.8%). Compared to patients that did not require re-operation, the re-operation group had a higher incidence of Type III olecranon fractures (17.4% vs 8.4%, p = 0.036) and Monteggia pattern injuries (13.5% vs 4.9%, p = 0.008). Recent heteregenous data suggests the hardware removal rate related to implant prominence is between 17–54%. Compared to the literature, this study demonstrated a lower rate at 15.6% with contoured anatomic plating. Also, those with more complex fracture patterns were more likely to require re-operation.
Osseointegration has been established as a promising approach for the reconstruction of amputated limbs, particularly for amputees suffering from traditional socket prosthesis (TSP). While Osseointegration was originally developed with a screw fixation design, several Osseointegration devices adopting a modern press-fit design have also been introduced. In this study, medium-term outcomes for patients with the two most common press-fit osseointegration implant used worldwide are analysed. This is a cross-sectional analysis containing a cohort of Osseointegration patients treated in several centres worldwide. We analyzed a total of 93 patients with an average follow-up time of 6.52 years. Functional, Mobility and patient reported outcomes were collected pre-operatively and during follow-up. All postoperative adverse events (infection, revision surgery, fractures, and implant failures) were also analyzed.Introduction

Hip arthroscopy (HA) is an effective treatment for various hip conditions but has a steep learning curve and its effect on long-term joint preservation is unclear. This study uses population-level data to assess (1) the 90-day complication rate, and (2) the frequency and timing of revision HA, total hip replacement (THR), and pelvic osteotomy (PO) following primary HA. We performed a retrospective analysis of the National Hospital Episode Statistics database, examining all patients who underwent primary HA in NHS hospitals in England from 2010 to 2023 using relevant OPCS-4 codes. We evaluated patient demographics, 90-day complications, and reoperation rates for revision HA, THR, and PO. Descriptive statistical analyses were performed to calculate frequencies and average time to reoperations. We included 22,401 HA procedures in the study. The mean LOS was 0.82±2.04 days. The 90-day readmission rate was 0.17% at a mean of 54.4±8.1 days. The most common reasons for readmission were reoperation (0.071%), followed by infection (0.031%), pulmonary embolism (0.027%), pain (0.022%), bleeding (0.018%), and deep vein thrombosis (0.004%). One patient died within 90 days. Overall, 4942 patients (22.1%) required further surgery at a mean of 2.71±2.27 years. The rates of revision HA, conversion to THR, and PO were 6.94%, 14.6%, and 0.50% at a mean of 2.39±1.79, 2.87±2.46, and 2.26±1.80 years respectively. Female patients had higher rates of reoperation than males for conversion to THR (9.99% vs 4.63%), revision HA (4.92% vs 2.02%), and subsequent PO (0.43% vs. 0.06%) (p<0.001). This study demonstrates a low short-term complication rate after primary HA, supporting existing literature. However, a large proportion of patients required further surgery, especially females. These findings highlight the need for careful patient selection and counselling before HA to optimise outcomes, as well as further research on factors influencing longer-term outcomes and cost-effectiveness.
Hip dysplasia is a common cause of hip pain in young adults. Pelvic osteotomy (PO) techniques are the gold standard for treating symptomatic patients, albeit technically demanding. This study aimed to (1) evaluate the 90-day complication rate, and (2) investigate the reasons, frequency and timing of reoperations following primary PO procedures. We retrospectively analysed the National Hospital Episode Statistics database, examining all patients aged over 14 who underwent PO in NHS England hospitals from 2010 to 2023. We identified index procedures and reoperations using relevant OPCS-4 codes. We analysed patient demographics, 90-day complications, and readmission rates for ipsilateral metalwork removal, revision PO, hip arthroscopy (HA), and THR conversion, and calculated the mean time to reoperations. This study included 1,348 PO cases (mean age: 28.7±9.1 years, 89.5% female). The mean hospital stay was 5.4±3.9 days, with a 90-day readmission rate of 0.52% at a mean of 51.0±17.2 days. The most common causes were infection (0.22%) and reoperation (0.15%). The 90-day rate of pulmonary embolism and deep vein thrombosis was 0.074%. One patient died within 90 days. Overall, 810 patients (60.1%) were readmitted for a subsequent hip procedure at a mean of 2.12±1.90 years following their primary PO. Metalwork removal was required in 616 patients (45.7%) at a mean of 1.70±1.19 years. Readmission rates for revision PO, HA, and THR, were 4.23% (mean time: 2.89±0.82 years), 4.15% (mean time: 2.91±2.28 years) and 6.01% (mean time: 5.24±3.08 years) respectively. This study highlights a low 90-day complication rate following primary PO, but a high reoperation rate, mainly for metalwork removal. We provide the most up-to-date report of revision PO, HA and THR conversion rates in England. These findings provide valuable insight that can facilitate informed decision-making, expectation-setting, and post-operative planning, also establishing a benchmark for future quality improvement.
Introduction and Objectives: The aim of this report is to present the complications that occur with percutaneous surgery for hallux valgus. Percutaneous surgery is based on a series of combined surgical procedures designed to resolve a deformity. Materials and Methods: We have reviewed the first 200 cases of percutaneous surgery in our centre. In 136 cases, a diagnosis of hallux valgus was made in association with metatarsalgia and deformity of the toes. There were 40 cases of hallux valgus alone, 24 cases of metatarsal-gias with toe deformities, and 10 cases of toe deformities alone. Patients were treated between February 2001 and February 2002 with a mean follow-up time of 8 months.
Waiting time to access medical care in Canada is 20% more than the international average. Delay in instituting care in trauma patients has been shown to correlate with higher complication rates and an increase in mortality. About 11% of all fractures occur in the femur and are usually treated operatively. Delay to operative treatment is a source of distress to patients and a major factor for poor outcome. Knowledge gaps exist for statistics on operative delay to fixation of femur fractures and the influence on complications and cost of treatment. This study describes (1) the effect of delay to fixation of femur fractures on complications and on the overall cost of care in hospitals in Quebec Province of Canada; and (2) proposes a time frame within which femur fractures should be operated on to minimize the risk of complications and reduce treatment cost. 6,520 adult patients operated for closed femoral fractures between July 1993 and December 2002 were reviewed. Data was accessed from (a) the Quebec Trauma Registry, (b) the hospitalised patients’ database, Mean operative delay for femoral fractures was 26.3 hours. Delay was associated with increased complications, ICU stay, length of stay (LOS), hospitalization costs and out-patient follow-up treatment costs. There was a progressive increase in these adverse events which was quite significant after the first 48 hours. ISS >15 predisposed to prolonged ICU stay, LOS and increased cost of treatment. All femur fractures appeared to have a predilection for over-65-year-olds and women. The major cost drivers of operative femur fracture treatment were ISS>15, operative delay ≥48 hours, occurrence of complications, and re-operations. Minimizing operative delay in femur fractures will not only mitigate patient suffering, but also reduce treatment and follow-up costs.
Limited literature exists providing comprehensive assessment of complications following opening wedge high tibial osteotomy (OWHTO). We performed a retrospective study of local patients who underwent OWHTO for isolated medial compartment knee osteoarthritis from 1997–2013. One hundred and fifteen patients met inclusion criteria. Mean follow-up = 8.4years. Mean age = 47 (range 32–62). Mean BMI = 29.1 (range 20.3–40.2). Implants used included Tomofix (72%), Puddu plate (21%) and Orthofix (7%) (no significant differences in age/ sex/ BMI). Wedge defects were filled with autologous graft (30%), Chronos (35%) or left empty (35%). Five year survival rate (conversion to arthroplasty) = 80%. Overall complication rate = 31%. 25% of patients suffered 36 complications including minor wound infections (9.6%), major wound infections (3.5%), metalwork irritation necessitating plate removal (7%), non-union requiring revision (4.3%), vascular injury (1.7%), compartment syndrome (0.9%), and other minor complications (4%). No thromboembolic complications were observed. A higher BMI (mean 34.2) was apparent in those patients suffering complications than those not (mean 26.9). No significant differences existed in complication rates relative to implant type, type of bone graft used or patient age at surgery.
Excessive opioid prescriptions after total joint arthroplasty (TJA) increase risks for adverse opioid related events, chronic opioid use, and increase the availability of opioids for unlawful diversion. Thus, decreasing postoperative prescriptions may improve quality after TJA. Concerns exist that a decrease in opioids prescribed may increase complications such as readmissions, emergency department (ED) visits or worsened patient reported outcomes (PROs). The purpose of this quality improvement study was to explore whether a reduction in opioids prescribed after TJA resulted in increased complications. Methods: Data originated from a statewide arthroplasty database (MARCQI). The database collects over 96% of all TJA performed in the state of Michigan, USA. Data was prospectively abstracted and included OMEs prescribed at discharge, readmissions, ED visits within 30 days and PROs. Data was collected one year before and after the creation of an opioid prescribing protocol that had decreased prescriptions by approximately 50% in opioid naive and tolerant patients. Trends were monitored using Shewhart control charts. 84,998 TJA over two-years were included. All groups showed a reduction in opioids prescribed. Importantly, no increased complications occurred concomitant to this reduction. No increases in ED visits or readmissions, and no decreases in KOOSJR/HOOSJR/PROMIS10 scores were noted in any of the groups. Using large data sets and registries can drive performance and improve quality. The MARCQI Postoperative opioid prescription recommendations and performance measures decreased total oral morphine equivalents prescribed over a large and diverse population by approximately 50% without decreasing PROs or increasing ED visits or hospital readmissions. A reduction in opioids prescribed after TJA can be accomplished safely and without an increase in complications across a large population.
Background. Recent years have witnessed a paradigm shift in the assessment of outcome in spine surgery, with patient-centred questionnaires replacing traditional surgeon-based assessments. The assessment of “complications” — loosely defined as new/unexpected problems arising as a result of surgery — has not enjoyed this same enlightened approach. Methods. Patients with lumbar degenerative disorders operated with the goal of pain relief, completed a questionnaire 1 year post-operatively enquiring about complications arising as a consequence of their operation. They rated the bothersomeness of any such complications on a 5-point adjectival scale. Global outcome of surgery and satisfaction were rated on 5-point Likert scales. Results. Of 2946 (92% compliance) patients completing the questionnaire, 861 (29%) reported complications, most commonly sensory disturbances (37% of those with complications) or ongoing pain (22%), followed by motor problems (9%), pain plus sensory disturbances (8%), and problems with wound healing (6%). The corresponding “bothersomeness” ratings for these were: 1% not at all, 23% slightly, 26% moderately, 31% very, and 19% extremely bothersome. Bothersomeness was significantly correlated with global outcome (Rho=0.51, p<0.0001) and satisfaction (Rho=0.43, p<0.0001). A good global outcome was reported by 80% of patients with no complications and only 58% of those with complications; satisfaction was 88% and 72%, respectively. Conclusion. Most complications reported by the patient are perceived to be at least moderately bothersome and are hence not inconsequential.
Management of highly displaced acromioclavicular joint (ACJ) injuries remain contentious. It is unclear if delayed versus acute reconstruction has an increased risk of fixation failure and complications. The primary aim of this was to compare complications of early versus delayed reconstruction. The secondary aim was to determine modes of failure of ACJ reconstruction requiring revision surgery. A retrospective study was performed of all patients who underwent operative reconstruction of ACJ injuries over a 10-year period (Rockwood III-V). Reconstruction was classed as early (<12 weeks from injury) or delayed (≥12 weeks). Patient demographics, fixation method and post-operative complications were noted, with one-year follow-up a minimum requirement for inclusion. Fixation failure was defined as loss of reduction requiring revision surgery. 104 patients were analysed (n=60 early and n=44 delayed). Mean age was 42.0 (SD 11.2, 17–70 years), 84.6% male and 16/104 were smokers. No difference was observed between fixation failure (p=0.39) or deep infection (p=0.13) with regards to acute versus delayed reconstruction. No patient demographic or timing of surgery was predictive of fixation failure on regression modelling. Overall, eleven patients underwent revision surgery for loss of reduction and implant failure (n=5 suture fatigue, n=2 endo-button escape, n=2 coracoid stress fracture and n=2 deep infection). This study suggests that delayed ACJ reconstruction does not have a higher incidence of fixation failure or major complications compared to acute reconstruction. For those patients with ongoing pain and instability following a trial of non-operative treatment, delayed reconstruction would appear to be a safe treatment approach.
Introduction: Anterior lumbar interbody fusion has become a frequently utilised procedure. The trend has been towards less invasive techniques including laparascopic and mini-open techniques. This report examines the results of one procedure and suggests appropriate tools to decrease the learning curve. Methods: Twenty-two patients with a mean age of 41 (17–78) underwent mini-open ALIF with threaded cortical bone dowels. The same senior surgeon performed all procedures (RFD). Indication for the procedure was discogenic pain verified by concordant discography after a failure of a minimum of six months non-operative treatment. Patients were followed at standard intervals.
The primary aim was to determine the rate of complications and re-intervention rate in a consecutive series of operatively managed distal radius fractures. Data was retrospectively collected on 304 adult distal radius fractures treated at our institution in a year. Acute unstable displaced distal radius fractures surgically managed within 28 days of injury were included. Demographic and injury data, as well as details of complications and their subsequent management were recorded. There were 304 fractures in 297 patients. The mean age was 57yrs and 74% were female. Most patients were managed with open reduction and internal fixation (ORIF) (n=278, 91%), with 6% (n=17) managed with manipulation and Kirschner wires and 3% (n=9) with bridging external fixation. Twenty-seven percent (n=81) encountered a post-operative complication. Complex regional pain syndrome was most common (5%, n=14), followed by loss of reduction (4%). Ten patients (3%) had a superficial wound infection managed with oral antibiotics. Deep infection occurred in one patient. Fourteen percent (n=42) required re-operation. The most common indication was removal of metalwork (n=27), followed by carpal tunnel decompression (n=4) and revision ORIF (n=4). Increasing age (p=0.02), male gender (p=0.02) and high energy mechanism of injury (p<0.001) were associated with developing a complication. High energy mechanism was the only factor associated with re-operation (p<0.001). This study has documented the complication and re-intervention rates following distal radius fracture fixation. Given the increased risk of complications and the positive outcomes reported in the literature, non-operative management of displaced fractures should be considered in older patients.
Anesthetic peripheral nerve blocks (PNB) have been shown to be more advantageous than general anesthesia in a variety of surgical operations. In comparison to conventional methods of general anesthesia, the choice of regional localized infiltration has been shown to shorten hospital stays, decrease hospital readmissions, allow early mobilization, and reduce narcotic use. Perioperative complications of PNBs have been reported at varying rates in literature. Thus, the purpose of this study was to provide a review on the clinical evidence of PNB complications associated with foot and ankle surgeries. A systematic review of the literature was completed using PubMed search terms: “lower extremity”, “foot and ankle”, “nerve block”, and “complications”. All studies reporting minor and major complications were considered along with their acute management, treatments, and postoperative follow up timelines. The range of complications was reported for Sensory Abnormalities, Motor Deficits, Skin and systemic complications (local anesthetic systemic toxicity & intravascular injections). A designation of the scientific quality (Level I-IV) of all papers was assigned then a summary evidence grade was determined. The search strategy extracted 378 studies of which 38 studies were included after criteria review. Block complications were reported in 20 studies while 18 studies had no complications to report. The quality of evidence reviewed ranged from Level I to Level IV studies with follow up ranging from twenty four hours to one-three year timelines. The range of complications for all studies reporting sensory abnormalities was 0.53 to 45.00%, motor deficits 0.05 to 16.22% and skin and systemic complications 0.05 to 6.67%. Sensory abnormalities that persisted at last follow up occurred in six studies with incidence ranging from 0.23 to 1.57%. Two studies reported motor complications of a foot drop with an incidence of 0.05% and 0.12%. When considering only the highest quality studies (Level 1) that had complications to report, the complications rate was 10.00% to 45.00% for sensory abnormalities, 7.81 to 16.22% for motor deficits, 6.67% for skin complications and 2.50% for systemic complications. High quality studies (Level I providing Summary Grade A Evidence) reporting all complications with a range of incidence from 0 to 45%. While most of these complications were not serious and permanent, some were significant including sensory abnormalities, foot drop and CRPS. Based on this systematic review of the current literature, the authors emphasize a significant rate of complications with PNB and recommend that patients are appropriately informed prior to consenting to these procedures.
Aim. The purpose of this study was to quantify the number of children treated with ESIN (elastic stable intra-medullary nails) at our institution and to determine what proportion of these nails have been removed and the time and difficulty taken to do so. Methods. Patients treated with ESIN between 2000 and 2005 were identified by database search. Their notes were reviewed to record patient and initial nailing details, and timing, difficulty and length of metalwork removal procedures.
Background: The purpose of this study was to evaluate the relationship between body mass index and early complications following total knee joint replacement surgery. Methods: 527 patients who underwent a primary knee replacement were included in this study. All these patients were subjected to a pre-operative assessment and then followed up at six weeks and one year following surgery. Any complication that occurred during this period was recorded.
Background: The occurrence of congenitally short metatarsals is associated with an abnormal gait and an aesthetically displeasing appearance. Similarly, short metacarpals result in severe cosmetic disfigurement, particularly in young female patients. Methods: We examined and performed bone lengthening surgery in 13 female and 2 male patients. Of these, procedures were conducted on 12 metatarsals of 8 patients, 4 metacarpals and 1 metatarsal of a single patient, 1 metacarpal and 1 metatarsal of a single patient and 7 metacarpals of 5 patients. The mean age of the patients who underwent metacarpal procedures was 14.5 (10–21) years while the mean age of those who underwent metatarsal procedures was 17.5 (10–25) years. The callotasis method was employed for these procedures and we used either a unilateral external fixator and/or a circular external fixator. Results: The mean healing index and increase in metacarpal length was 1.6 (1.1–2.3) months/cm and 17.6 (13–26) mm, respectively. The mean follow-up period for patients who underwent metacarpal lengthening was 57.5 (12–96) months. The mean healing index and increase in metatarsal length was 1.6 (1.0–2.0) months/cm and 24.3 (20–30) mm respectively. The mean follow-up period for patients who underwent metatarsal lengthening was 48.3 (12–72) months. The preoperative AOFAS (American Orthopaedic Foot and Ankle Society) scores were good in 5 and excellent in 9 cases. The functional scores of metatarso-phalangial (MTP) joint of lengthened metatarsals for the lesser toe were excellent in 12 and good in 2 cases based on the AOFAS scoring system. All patients who underwent metacarpal lengthening reported that they were satisfied and could conduct their daily activities with good functional and aesthetic results.
A consensus regarding management of calcaneal fractures eludes orthopaedic surgeons. While operative treatment has gained more acceptance, surgical morbidity remains high. We undertook a retrospective review of early complications and radiological outcomes following internal fixation of calcaneal fractures in our unit over 15 months. A consecutive series of 33 patients who underwent fixation of the Calcaneus was selected. Patient records, X-rays and scans were reviewed. 37 fractures in 33 patients underwent fixation. 81 % were male. Mean age at surgery was 37yrs (19 -59yrs). 35 % were operated within 1 wk of injury and 13% after 2 wks of injury. 43% were Sanders' type III, 18% type II and 13% tuberosity avulsion fractures. 63% had a reversed/zero Bohler's angle. Mean post-op Bohler's angle was 32 degrees. Overall complication rate was 32%, with a combined deep infection rate of 8%. All patients with infection were male, and 70% were smokers. 86% were above 40yrs of age (mean 47yrs). The deep infection rate for intra-articular fractures was 3% and for tuberosity avulsion fractures 40%. Majority of patients with wound complications had been operated within 7 days of injury. Males over 40yrs and smokers seem to be at most risk of wound complications. Time to surgery/delay in surgery up to 2 wks did not seem to have any adverse consequences.
Aims: Lengthening of bones with Ilizarov method is acknowledged method as well very inconvenient. First inconvenience is long lasting of immobilization in external stabilizer, responsible for joints contracture and muscles atrophy. Use of interlocking nail makes possible removal of stabilizer immediately after finishing of lengthening without risk of deformity of fresh bone callus. Methods: From 1999 to 2001 we used this method in the treatment of 11 patients age 13–23 years [~16,9], with shortening of femur 3–8 cm [~4,9]. Etiology of shortening was: congenital [8], aseptic necrosis of femoral head [2] and comminuted fracture of femoral shaft [1]. During surgery we cut cortex of femur, than interlocking nail and finally external stabilizer were applied. After we reached planned lengthening nail was locked and stabilizer was removed. For complications we used Paley classification. Results: We received planned length of femur in 10 cases. Average time of applying of external stabilizer was 14 days/1cm of lengthening. Problems: fracture of femoral shaft without displacement during driving of the nail [1], pin site infection of soft tissues and transient restriction of movements of knee in all cases. Obstacles: wedging of the nail [2], fracture of femur after removal of the nail [1] and deep infections along the nail [1].
We aimed to analyse complication rates following medial opening-wedge high tibial osteotomy (OWHTO) for knee OA. A regional retrospective cohort study of all patients who underwent HTO for isolated medial compartment knee OA from 2003–2013. 115 OWHTO were performed. Mean age = 47 (95%CI 46–48). Mean BMI = 29.1 (95%CI 28.1–30.1). Implants used: 72% (n=83) Tomofix, 21% (n=24) Puddu plate, 7% (n=8) Orthofix Grafts used: 30% (n=35) autologous, 35% (n=40) artificial and 35% (n=40) no graft. 25% (n=29) of patients suffered 36 complications.
With the widespread legalization of cannabis across the United States, well-powered studies evaluating the impact of cannabis use disorder on outcomes following primary total hip arthroplasty are warranted. Therefore, the aim of this study was to determine whether cannabis use disorder has an effect on patients who undergo primary hip arthroplasty in terms of: 1) hospital lengths of stay (LOS); 2) medical complications; 3) implant-related complications; and 4) costs of care. Using an administrative database, patients who underwent primary total hip arthroplasty and had cannabis use disorder were matched to a cohort who did not in a 1:5 ratio by age, sex, and various medical comorbidities. This yielded 44,154 patients; 7,361 who had cannabis use disorder and 36,793 who did not. Variables for analysis included postoperative LOS, 90-day medical complications, 2-year implant-related complications, and 90-day costs of care. Mann-Whitney-U tests were used to compare LOS and costs. Multivariate logistic regression analyses were used to calculate the odds ratios (ORs) of developing complications. A Introduction
Methods
Background:. Pilon fractures are complex intra-articular fractures of the tibial plafond associated with significant short and long morbidity. Minimising surgical complications is essential. Methods:. Clinical and radiological outcomes in 49 patients with AO type 43B and 43C fractures were evaluated retrospectively. Definitive management depended on patient factors, soft tissue injury and fracture pattern. Results:. The majority of fractures (n=26, 53%) were C3 type. 9 fractures were open (18%), grade 3A or 3B. 34 patients (69%) were definitively managed with open reduction and internal fixation (ORIF) predominantly through an anterior approach. 15 (31%) had mini-open or percutaneous plafond reduction and external fixation. No medial plates were used. There were no deep infections.
Introduction: Unicompartmental osteoarticular defects of the knee are challenging due to demands of stability and function of this weight-bearing joint. Prostheses reconstruction often requires sacrificing the uninvolved compartment. Osteoarticular allograft reconstruction can restore the anatomy, and allows reattaching soft tissue structures such as meniscus and ligaments from the host. The purpose of this study was to perform a survival analysis of unicompartimental osteoarticular allografts of the knee and evaluate their complications. Material and Methods: Forty unicompartmental osteo-articular allograft of the knee performed in 38 patients during the period 1962–2001, were followed for a mean of 11 years. In 36 patients, the bone defect was created by the resection of a tumor (33 giant cell tumors, 1 osteogenic sarcoma, 1 chondrosarcoma and 1 malignant fibrous histiocytoma) and in the remaining two by an open fracture. Twenty nine transplants were located at the femur that includes 11 medial and 18 lateral condyles. Eleven transplants were located at the tibia, including 4 medial and 7 lateral tibial plateaus. According to the reconstructed compartment, host meniscus and ligaments were reattached to the graft. Rigid internal fixation with plates and screws were used in each patient. Allografts survival from the date of implantation to the date of revision or the time of the latest follow-up was determined with the use of the Kaplan-Meier method.
Purpose of the Study: We evaluated the complications of proximal humeral fractures, which are treated with locked plates. Materials and Methods: 103 patients (70 female, 33 male) with proximal humeral fractures with an average follow-up time of 19 months (2 weeks– 43 months) and an average 62,1 (21–90) years of age are treated with open reduction and internal fixation from September 2005 to April 2009 in our clinic. Internal fixation was performed with PHILOS plate in 93 patients and S3 Humeral plate in 10 patients. Early and late complications that are encountered during the follow-up time is presented. Results:
Aims. As the population ages and the surgical complexity of lumbar spinal surgery increases, the preoperative stratification of risk becomes increasingly important. Understanding the risks is an important factor in decision-making and optimizing the preoperative condition of the patient. Our aim was to determine whether the modified five-item frailty index (mFI-5) and nutritional parameters could be used to predict postoperative complications in patients undergoing simple or complex lumbar spinal fusion. Methods. We retrospectively reviewed 584 patients who had undergone lumbar spinal fusion for degenerative lumbar spinal disease. The 'simple' group (SG) consisted of patients who had undergone one- or two-level posterior lumbar fusion. The 'complex' group (CG) consisted of patients who had undergone fusion over three or more levels, or combined anterior and posterior surgery. On admission, the mFI-5 was calculated and nutritional parameters collected. Results.
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%.
Aims. Plate and screw fixation has been the standard treatment for painful conditions of the wrist in non-rheumatoid patients in recent decades. We investigated the complications, re-operations, and final outcome in a consecutive series of patients who underwent wrist arthrodesis for non-inflammatory arthritis. Patients and Methods. A total of 76 patients, including 53 men and 23 women, with a mean age of 50 years (21 to 79) underwent wrist arthrodesis.
Nerve blocks are a common form of peri-operative analgesia that is administered for patients undergoing joint Replacement surgeries. The long term sequel following these peripheral nerve blocks used in total knee replacement not reported in the literature. Nerve blocks given under the guidance of nerve stimulators are in practice in most of the hospitals and are considered safe. We report a series of two cases with residual neurological deficit following these peripheral nerve blocks in total knee replacements. In both these cases the femoral, sciatic, obturator and lateral cutaneous nerve of thigh were blocked with 0.25% of Bupivacaine with the help of a nerve stimulator. First patient post operatively had residual numbness in the right lower leg after 4 weeks of surgery. Nerve conduction studies confirmed absent response in right Saphenous and superficial peroneal nerves. Patient has no improvement in her neurological deficit even after 16 months post operatively. Further to this she developed complex regional pain syndrome on the affected side. Second patient post operatively developed knee extensor weakness of grade II/V and loss of sensation in femoral nerve distribution. Nerve conduction studies confirmed severe femoral nerve damage around groin. She went through a turbulent phase, knee stiffness range of movements 0–20 degrees requiring Manipulation Under Anaesthesia, later Exploration and Release of adhesions which improved her range of movements to 0–95 degrees. At 12 months post operative the neurological status improved to grade 3/5 in knee extensors. Conclusion: Long term
The Achilles tendon is commonly operated on, but has associated wound complications, ranging from 7–14% in previously reported series larger than 100 cases. We report a retrospective review of one surgeon’s practice conducted to assess the prevalence of wound complications associated with acute and chronic rupture repair, peritenolysis, tenodesis, debridement, retrocalcaneal exostectomy/bursectomy, and management of calcific tendinopathy of the Achilles tendon. The study evaluated the incidence of infection, and other wound complications such as suture reactions, scar revision, hematoma, incisional neuromas and granuloma formation. A total of 219 surgical cases were available for review (140 males, 70 females; average age at the time of surgery: 46.5 ± 12.6 years, range 16–75). Seven patients experienced a wound infection, three had keloid formation, six had suture granulomas, and six had suture abscesses, with an overall complication rate of 22 of 219 surgeries (10.1%). There were no hematomas. Seven patients had additional surgery following their wound complications; some had simple granuloma excision, while one necessitated a flap. Patients with risk factors such as diabetes, smoking and Rheumatoid arthritis necessitating steroids were more likely to have a wound complication, (Fisher’s Exact Test, P=.03).
Purpose. To document the incidence and nature of complications associated with hemiepiphysiodesis using a screw and plate device (8-plate, Orthofix). Methods. We reviewed case notes and radiographs of 71 children (130 segments) with lower limb deformities treated with temporary hemiepiphyseal arrest using the 8-plate. 96% of deformities were in the coronal plane, 4% sagittal. 72% of coronal deformities demonstrated valgus malalignment. We defined three types of complications:. early (perioperative) complications eg infection and/or wound breakdown, bleeding, neurological impairment. implant related complications such as soft tissue irritation, plate breakage or migration,. complications involving the growth plate including rebound deformity, early physeal closure or iatrogenic deformity.
Background: The Calcaneus is the largest of the tarsal bones. 2% of all adult and 60 % of all tarsal fractures involve the Calcaneus. A true consensus regarding the management of these fractures still eludes orthopaedic surgeons. While operative treatment for displaced fractures has gained more acceptance in the last decade, surgical morbidity still remains high. Aim: A retrospective review of the early complications and radiological outcomes following open reduction and internal fixation of displaced calcaneal fractures in our unit over the last 15 months. Methods: A consecutive series of 33 patients who underwent surgical fixation of the Calcaneus was selected. Patient records, X rays and scans were reviewed. Mode and nature of injury, life style factors, surgical complications and Bohler’s angles were analysed. Results: 37 fractures in 33 patients underwent operative fixation. 81 % were male. Mean age at surgery was 37yrs (range19–59). 35 % were operated within 1 week of the injury and 13% after 2 weeks of injury. 43% were Sanders’ type III, 18% type II and 13% tuberosity avulsion fractures. 63% of patients had a reversed or zero Bohler’s angle. Mean post-op Bohler’s angle was 32 degrees. Overall complication rate was 32%, with a combined deep infection rate of 8%. All patients with infection were male, and 70% were smokers. 86% were above 40yrs of age (mean 47yrs). The deep infection rate for intra-articular fractures was 3% and for tuberosity avulsion fractures 40%. Majority of patients with wound complications had been operated within 7 days of injury. 4 patients had persisting pain requiring removal of metal work. Discussion: Our study highlights that there are significant risks associated with operative management of calcaneal fractures. Male patients over the age of 40yrs who are smokers seem to be at most risk of wound complications. Time to surgery or delay in surgery up to 2 weeks did not seem to have any adverse consequences.
Previous studies have indicated that prolonged surgical time may lead to higher rates of infection following total hip arthroplasty (THA). The purpose of this study was to evaluate the influence of surgical time on 30-day complications following THA and to determine if there was a time interval associated with worse outcomes. Patients ≥18 years who underwent THA between 2005 and 2016 were identified from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database using procedural codes. Patients with surgical durations >240 minutes were excluded. Patient demographics, operation length, and 30-day major and minor complications were ascertained. Multivariable regression was used to determine if the rate of complications differed depending on length of operation, while adjusting for relevant covariables, and to identify independent predictors of operation length. Covariables of interest included age, sex, American Society of Anaesthesiologists (ASA) class, smoking status, functional status, comorbidities, anesthesia type, and Body Mass Index (BMI). A total of 131,361 THA patients (average age 65 ±12 years) were identified from the database. Of these, 2,177 (1.64%) experienced a major complication, and 3,504 (2.64%) experienced a minor complication within 30-days of the initial procedure. Average operation length was 91.9 minutes (range 20 – 240 minutes). Independent predictors of prolonged operation length included overweight/obese BMI, male sex, cancer, dependent functional status, epidural anaesthetic, lower pre-operative hematocrit, and ASA class II, III or IV vs. I Alternatively, older age, current smoking, and spinal anaesthetic were associated with shorter surgical durations. Unadjusted rates of both major and minor complications were significantly higher for patients whose operation lengths were ≥ 120 minutes (P>0.001). Specifically, patients whose operations lasted ≥ 120 minutes had higher rates of septic shock, sepsis, pulmonary embolism (PE), deep vein thrombosis (DVT), urinary tract infection (UTI), renal insufficiency, surgical site infection(SSI) and wound disruption. After covariable adjustment, surgical durations of 90–119 minutes increased the risk of minor complications by 1.2 (95%Confidence interval [95%CI] 1.1–1.3), while surgical durations of 120–179 minutes increased the risk of major complications by 1.4 (95%CI 1.3 – 1.6), and minor complications by 1.4 (95%CI 1.2 – 1.5), and surgical durations ≥180 minutes increased the risk of major complications by 2.1 (95%CI 1.8 – 2.6), and minor complications by 1.9 (95%CI 1.6 – 2.3). There was no difference in the overall risk of complications for operation times lasting 20 – 39, 40 – 59, or 60 – 89 minutes (P>0.05). In terms of specific complications, operation length ≥90 minutes was determined to be an independent risk factor for deep and superficial incisional SSI, as well as wound disruption, while operation length ≥ 120 minutes was an independent risk factor for sepsis, UTI, and deep, non-incisional SSI and operation length ≥ 180 minutes was an independent risk factor for PE, DVT, and cardiac arrest (p < 0 .05). These data indicate that prolonged surgical durations may be an independent predictor of major and minor complications following THA. This suggests that quality improvements could be made to improve operating room efficiency and surgical times and therefore postoperative outcomes.
For soft tissue sarcoma patients receiving preoperative radiation therapy, wound complications are common and potentially devastating; they may result in multiple subsequent surgeries and significant patient morbidity. The purpose of this study was to assess the feasibility of intraoperative indocyanine green fluorescent angiography (ICGA) as a predictor of wound complications in resections of irradiated soft tissue sarcoma of the extremities. A consecutive series of patients of patients with soft tissue sarcoma of the extremities or pelvis who received neoadjuvant radiation and a subsequent radical resection received intraoperative ICGA with the SPY PHI device (Stryker Inc, Kalamazoo MI) at the time of closure. Three fellowship trained Orthopaedic Oncologic Surgeons were asked to prospectively predict likelihood of wound complications based on fluorescence. Retrospective analysis of fluorescence signal along multiple points of the wound length was performed and quantified. The primary endpoint was wound complication, defined as delayed wound healing or wound dehiscence, within 3 months of surgery. An a priori power analysis demonstrated that 5 patients were necessary to achieve statistical significance. Univariate and multivariate statistical analyses were performed to identify predictors of wound complications. 14 patients were consecutively imaged. The diagnosis was undifferentiated pleomorphic sarcoma in 9 (64.3%) of patients; 11 (78.6%) tumors were high grade. There were 6 patients with wound complications classified as “aseptic” in 5 cases and secondary to hematoma in 1 case. Using the ICGA, blinded surgeons correctly predicted wound complications in 75% of cases. In the area of wound complication, the mean % of maximal signal for wound complications was 49% during the inflow phase and 48% during the peak phase. The mean % maximal signal for peri-incisional tissue without wound complications was 77% during the inflow phase and 83% during the peak phase (p=0.003 and p<0.001). During the inflow phase, a mean ratio of normal of 0.62 maximized the area under the curve (AUC=0.90) for predicting wound complications with a sensitivity of 100% and specificity of 77.4%. During the peak phase, a mean ratio of normal of 0.55 maximized the area under the curve (AUC=0.95) for predicting wound complications with a sensitivity of 88.9% and a specificity 100%. Intraoperative use of indocyanine green fluorescent angiography may help to predict wound complications in patients undergoing resection of preoperatively irradiated soft tissue sarcomas of the extremities and pelvis. Future studies are necessary to validate this technology in a prospective manner and to determine if interventions can be instituted to prevent predicted wound complications.
Background: The interpretation of safety data from clinical studies such as complication risks requires clear definition of targeted and documented complication events. In addition a standardized classification of complications is required to allow appropriate comparison of safety data between studies and treatment groups. This presentation highlights a proposal for a standardized management and classification of complication data to initiate and seek consensus among trauma surgeons active in clinical documentation and research. Methods: Complication events are examined regarding their timing of occurrence as well as their potential causal inter-relationship for any given patient. While independent events are numbered sequentially, directly associated events (e.g. a fracture collapse and implant screw perforation into a joint) receives the same complication number.
