Introduction

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.

Introduction

Wide, tumor-like resection for chronic osteomyelitis (COM), a standard practice previously, has been challenged recently with adequate, local debridement. This paper reviews the evolution of surgical debridement for long bone osteomyelitis, and presents the outcome of adequate debridement in a tertiary bone infection unit.

Functional outcomes are important for patients with bone tumors undergoing lower extremity endoprosthetic reconstruction; however, there is limited empirical evidence evaluating function longitudinally. The objective of this study was to determine the changes in function over time in patients undergoing endoprosthetic reconstructions of the proximal femur, distal femur and proximal tibia.

We conducted a secondary analysis of functional outcome data from the Prophylactic Antibiotic Regimens in Tumor Surgery (PARITY) trial. Patient function was assessed with the Musculoskeletal Tumor Society Score 93 (MSTS) and the Toronto Extremity Salvage Score (TESS), which were administered preoperatively and at 3, 6 and 12 months postoperatively. Both instruments are scored from 0-100, with higher scores indicated greater function. Mean functional scores were evaluated over time and we explored for differences among patients undergoing proximal femur reconstructions (PFR), distal femur reconstructions (DFR) and proximal tibia reconstructions (PTR). The patient-importance of statistically significant differences in function was evaluated utilizing the minimally important difference (MID) of 12 for the MSTS and 11 for the TESS. We explored for differences in change scores between each time interval with paired t-tests. Differences based on endoprosthetic reconstruction undertaken were evaluated by analysis of variance and post-hoc comparisons using the Tukey test.

A total of 573 patients were included. The overall mean MSTS and TESS scores were 77.1(SD±21) and 80.2(SD±20) respectively at 1-year post-surgery, demonstrating approximately a 20-point improvement from baseline for both instruments. When evaluating change scores over time by type of reconstruction, PFR patients experienced significant functional improvement during the 3-6 and 6-12 month follow-up intervals, DFR patients demonstrated significant improvements in function at each follow-up interval, and PTR patients reported a significant decrease in function from baseline to 3 months, and subsequent improvements during the 3-6 and 6-12 month intervals.

On average, patients undergoing endoprosthetic reconstruction of the lower extremity experience important improvements in function from baseline within the first year. Patterns of functional recovery varied significantly based on type of reconstruction performed. The results of this study will inform both clinicians and patients about the expected rehabilitation course and functional outcomes following endoprosthetic reconstruction of the lower extremity.

Introduction

Derotation osteotomies are commonly performed in paediatric orthopaedic and limb reconstruction practice. The purpose of this study was to determine whether the use of a digital inclinometer significantly improves the accuracy in attaining the desired correction.

Progressive collapsing foot deformity (PCFD) is a common condition with an estimated prevalence of 3.3% in women greater than 40 years. Progressive in nature, symptomatic flatfoot deformity can be a debilitating condition due to pain and limited physical function; it has been shown to have one of the poorest preoperative patient reported outcome scores in foot and ankle pathologies, second to ankle arthritis. Operative reconstruction of PCFD can be performed in a single-stage manner or through multiple stages. The purpose of this study is to compare costs for non-staged (NS) flatfoot reconstructions, which typically require longer hospital stays, with costs for staged (S) reconstructions, where patients usually do not require hospital admission. To our knowledge, the comparison between single-staged and multi-staged flatfoot reconstructions has not been previously done. This study will run in conjunction with one that compares rates of complications and reoperation, as well as patient reported outcomes on function and pain associated with S and NS flatfoot reconstruction. Overall, the goal is to optimize surgical management of PCFD, by addressing healthcare costs and patient outcomes.

At our academic centre with foot and ankle specialists, we selected one surgeon who primarily performs NS flatfoot reconstruction and another who primarily performs S procedures. Retrospective chart reviews of patients who have undergone either S or NS flatfoot reconstruction were performed from November 2011 to August 2021. Length of operating time, number of primary surgeries, length of hospital admission, and number of reoperations were recorded. Cost analysis was performed using local health authority patient rates for non residents as a proxy for health system costs. Rates of operating room per hour and hospital ward stay per diem in Canadian dollars were used. The analysis is currently ongoing.

72 feet from 66 patients were analyzed in the S group while 78 feet from 70 patients were analyzed in the NS group. The average age in the S and NS group are 49.64 +/− 1.76 and 57.23 +/− 1.68 years, respectively. The percentage of female patients in the S and NS group are 63.89% and 57.69%, respectively. All NS patients stayed in hospital post-operatively and the average length of stay for NS patients is 3.65 +/− 0.37 days. Only 10 patients from S group required hospital admission.

The average total operating room cost including all stages for S patients was $12,303.12 +/− $582.20. When including in-patient ward costs for patients who required admission from S group, the average cost for operating room and in-patient ward admission was $14,196.00 +/− $1,070.01 after flatfoot reconstruction.

The average in-patient ward admission cost for NS patients was $14,518.83 +/− $1,476.94 after flatfoot reconstruction. The cost analysis for total operating room costs for NS patients are currently ongoing. Statistical analysis comparing S to NS flatfoot reconstruction costs are pending.

Preliminary cost analysis suggests that multi-staged flatfoot reconstruction costs less than single-staged flatfoot reconstruction. Once full assessment is complete with statistical analysis, correlation with patient reported outcomes and complication rate can guide future PCFD surgical management.

Introduction

Non-union is an unfortunate outcome of the fracture healing process for some patients; with an estimated annual incidence of 17.4- 18.9 per 100,00. The management of these patients depicts a significant clinical challenge for surgeons and financial burden to health services. External ultrasound stimulation devices (Exogen^TM) have been highlighted as a novel non invasive therapy to achieve union in cases of delayed and non-union. The aim of the current study was to assess the rate of union in patients using Exogen^TM therapy for delayed fracture union in a district general hospital.

Diffuse-type Tenosynovial Giant-Cell Tumour (d-TGCT) of large joints is a rare, locally aggressive, soft tissue tumour affecting predominantly the knee. Previously classified as Pigmented Villonodular Synovitis (PVNS), this monoarticular disease arises from the synovial lining and is more common in younger adults. Given the diffuse and aggressive nature of this tumour, local control is often difficult and recurrence rates are high. Current literature is comprised primarily of small, and a few larger but heterogeneous, observational studies. Both arthroscopic and open synovectomy techniques, or combinations thereof, have been described for the treatment of d-TGCT of the knee.

There is, however, no consensus on the best approach to minimize recurrence of d-TGCT of the knee. Some limited evidence would suggest that a staged, open anterior and posterior synovectomy might be of benefit in reducing recurrence. To our knowledge, no case series has specifically looked at the recurrence rate of d-TGCT of the knee following a staged, open, posterior and anterior approach. We hypothesized that this approach may provide better recurrence rates as suggested by larger more heterogeneous series.

A retrospective review of the local pathology database was performed to identify all cases of d-TGCT or PVNS of the knee treated surgically at our institution over the past 15 years. All cases were treated by a single fellowship-trained orthopaedic oncology surgeon, using a consistent, staged, open, posterior and anterior approach for synovectomy. All cases were confirmed by histopathology and followed-up with regular repeat MRI to monitor for recurrence. Medical records of these patients were reviewed to extract demographic information, as well as outcomes data, specifically recurrence rate and complications. Any adjuvant treatments or subsequent surgical interventions were noted.

Twenty-three patients with a minimum follow-up of two years were identified. Mean age was 36.3 at the time of treatment. There were 10 females and 13 males. Mean follow-up was seven and a half years. Fourteen of 23 (60.9%) had no previous treatment. Five of 23 had a previous arthroscopic synovectomy, one of 23 had a previous combined anterior arthroscopic and posterior open synovectomy, and three of 23 had a previous open synovectomy. Mean time between stages was 87 days (2.9 months). Seven of 23 (30.4%) patients had a recurrence. Of these, three of seven (42.9%) were treated with Imatinib, and four of seven (57.1%) were treated with repeat surgery (three of four arthroscopic and one of four open).

Recurrence rates of d-TGCT in the literature vary widely but tend to be high. In our retrospective study, a staged, open, anterior and posterior synovectomy provides recurrence rates that are lower than rates previously reported in the literature. These findings support prior data suggesting this approach may result in better rates of recurrence for this highly recurrent difficult to treat tumour.

Acromioclavicular joint injuries are one of the most common injuries in the shoulder girdle complex. Surgical management is considered based on patient profile, level of activity, pain, and classification of injury. To date, a vast array of surgical techniques have been proposed and described in the literature, a possible reason being that the optimal solution is still uncertain. The aim of this study is to determine the efficacy of an alternative surgical technique.

This study is a retrospective case series of 80 patients that have been operated by a single surgeon over a period of 6 years. A novel surgical technique, the ‘BiPOD method’, was applied where a synthetic artificial ligament (LARS®) is used to reconstruct and reduce the acromioclavicular joint.

The technique is done in a reproducible manner, where a single continuous artificial ligament is used to reduce and reconstruct both, the coracoclavicular and acromioclavicular ligament complexes to achieve bidirectional stability. Patients were followed-up postoperatively, either clinically where possible or telephonically. The Acromioclavicular Joint Instability Score (ACJI) and radiographic measurements were used to determine the clinical and surgical outcome of the surgery.

Radiographic parameters, measuring the reduction of the coracoclavicular- and acromioclavicular joint, were analysed and documented. The results showed marked improvement in both, the coracoclavicular distance and acromioclavicular distance. Clinically, using the ACJI scoring system, the patients reported substantial improvement in pain and function. Complications were recorded but were insignificant.

The BiPOD surgical technique, making use of an artificial LARS® ligament, has proven acceptable outcomes in the surgical management of acromioclavicular joint dislocations.

The presence of metastatic bone disease (MBD) often necessitates major orthopaedic surgery. Patients will enter surgical care either through emergent or electively scheduled care pathways. Patients in a pain crisis or with an acute fracture are generally admitted via emergent care pathways whereas patients with identified high-risk bone lesions are often booked for urgent yet scheduled elective procedures. The purpose of this study is to compare the post-operative outcomes of patients who present through emergent or electively scheduled care pathways in patients in a Canadian health care system.

We have conducted a retrospective, multicenter cohort study of all patients presenting for surgery for MBD of the femur, humerus, tibia or pelvis in southern Alberta between 2006 and 2021. Patients were identified by a search query of all patients with a diagnosis of metastatic cancer who underwent surgery for an impending or actual pathologic fracture in the Calgary, South and Central Alberta Zones. Subsequent chart reviews were performed. Emergent surgeries were defined by patients admitted to hospital via urgent care mechanisms and managed via unscheduled surgical bookings (“on call list”). Elective surgeries were defined by patients seen by an orthopaedic surgeon at least once prior to surgery, and booked for a scheduled urgent, yet elective procedure. Outcomes include overall survival from the time of surgery, hospital length of stay, and 30-day hospital readmission rate.

We have identified 402 patients to date for inclusion. 273 patients (67.9%) underwent surgery through emergent pathways and 129 patients (32.1%) were treated through urgent, electively scheduled pathways. Lung, prostate, renal cell, and breast cancer were the most common primary malignancies and there was no significant difference in these primaries amongst the groups (p=0.06). Not surprisingly, emergent patients were more likely to be treated for a pathologic fracture (p<0.001) whereas elective patients were more likely to be treated for an impending fracture (p<0.001). Overall survival was significantly shorter in the emergent group (5.0 months, 95%CI: 4.0-6.1) compared to the elective group (14.9 months 95%CI: 10.4-24.6) [p<0.001]. Hospital length of stay was significantly longer in the emergent group (13 days, 95%CI: 12-16 versus 5 days, 95%CI: 5-7 days). There was a significantly greater rate of 30-day hospital readmission in the emergent group (13.3% versus 7.8%) [p=0.01].

Electively managed MBD has multiple benefits including longer post-operative survival, shorter length of hospital stay, and a lower rate of 30-day hospital readmission. These findings from a Canadian healthcare system demonstrate clinical value in providing elective orthopaedic care when possible for patients with MBD. Furthermore, care delivery interventions capable of decreasing the footprint of emergent surgery through enhanced screening or follow-up of patients with MBD has the potential to significantly improve clinical outcomes in this population. This is an ongoing study that will justify refinements to the current surgical care pathways for MBD in order to identify patients prior to emergent presentation. Future directions will evaluate the costs associated with each care delivery method to provide opportunity for health economic efficiencies.

Cartilage lesions vary in the spectrum from benign enchondromas to highly malignant dedifferentiated chondrosarcomas. From the treatment perspective, enchondromas are observed, Grade 1 chondrosarcomas are curetted like aggressive benign tumors, and rest are resected like other sarcomas. Although biopsy for tissue diagnosis is the gold standard for diagnosis and grade determination in chondrosarcoma, tumor heterogeneity limits the grading in patients following a biopsy. In the absence of definite pre-treatment grading, a surgeon is therefore often in a dilemma when deciding the best treatment option. Radiology has identified aggressive features and aggressiveness scores have been used to try and grade these tumors based on the imaging characteristics but there have been very few published reports with a uniform group and large number of cases to derive a consistent scoring and correlation.

The authors asked these study questions :(1) Does Radiology Aggressiveness and its Score correlate with the grade of chondrosarcoma? (2) Can a cut off Radiology Agressiveness Score value be used to guide the clinician and add value to needle biopsy information in offering histological grade dependent management?

A retrospective analysis of patients with long bone extremity intraosseous primary chondrosarcomas were correlated with the final histology grade for the operated patients and Radiological parameters with 9 parameters identified a priori and from published literature (radiology aggressiveness scores - RAS) were evaluated and tabulated. 137 patients were identified and 2 patients were eliminated for prior surgical intervention. All patients had tissue diagnosis available and pre-treatment local radiology investigations (radiographs and/or CT scans and MRI scans) to define the RAS parameters.

Spearman correlation has indicated that there was a significant positive association between RAS and final histology grading of long bone primary intraosseous chondrosarcomas. We expect higher RAS values will provide grading information in patients with inconclusive pre-surgery biopsy to tumor grades and aid in correct grade dependant surgical management of the lesion. Prediction of dedifferentiated chondrosarcoma from higher RAS will be attempted and a correlation to obtain a RAS cut off, although this may be challenging to achieve due to the overlap of features across the intermediate grade, high grade and dedifferentiated grades.

Radiology Aggressiveness correlates with the histologic grade in long bone extremity primary chondrosarcomas and the correlation of radiology and biopsy can aid in treatment planning by guiding us towards a low-grade neoplasm which may be dealt with intralesional extended curettage or high-grade lesion which need to be resected. Standalone RAS may not solve the grading dilemma of primary long bone intraosseous chondrosarcomas as the need for tissue diagnosis for confirming atypical cartilaginous neoplasm cannot be eliminated, however in the event of a needle biopsy grade or inconclusive open biopsy it may guide us towards a correlational diagnosis along with radiology and pathology for grade based management of the chondrosarcoma.

Fractures of the ankle are common, and they mostly affect young adults. Wound complications are not uncommon following the fixation of these fractures. This study evaluated the impact of HIV on wound healing after plate osteosynthesis in patients with closed ankle fractures.

This is an observational retrospective study of patients operated on at a tertiary level hospital. We reviewed hospital records for patients above 18 years of age who presented with wound breakdown following ankle open reduction and internal fixation. The patients’ hospital records were retrieved to identify all the patients treated for closed ankle fractures and those who developed wound breakdown. Patients with Pilon fractures were excluded. The National Health Laboratory System (NHLS) database was accessed to retrieve the CD4 count, viral load, haematology study results, and biochemistry results of these patients at the time of surgery and subsequent follow-up. The x-rays were retrieved from the electronic picture archiving system (PACS) and were assessed for fracture union at a minimum of 3 months follow-up.

We reviewed the medical records of 172 patients with closed ankle fractures treated from 2018 to 2022. Thirty-one (18.0%) developed wound breakdown after surgery, and they were all tested for HIV. Most of the patients were male (58.0%), and the average age of the cohort was 43.7 years (range: 21 years to 84 years). Ten of these patients (32.2%) were confirmed HIV positive, with CD4 counts ranging from 155 to 781. Viral load levels were lower than detectable in 40% of these patients. All patients progressed to fracture union at a minimum of 3 months follow-up.

We observed no difference between HIV-positive and HIV-negative patients in terms of wound breakdown and bone healing post-plate osteosynthesis for closed ankle fractures.

Distal femur fractures (DFF) are common, especially in the elderly and high energy trauma patients. Lateral locked osteosynthesis constructs have been widely used, however non-union and implant failures are not uncommon. Recent literature advocates for the liberal use of supplemental medial plating to augment lateral locked constructs. However, there is a lack of proprietary medial plate options, with some authors supporting the use of repurposing expensive anatomic pre-contoured plates. The aim of this study was to investigate the feasibility of a readily available cost-effective medial implant option.

A retrospective analysis from January 2014 to June 2022 was performed on DFF (primary or revision) managed with supplemental medial plating with a Large Fragment Locking Compression Plate (LCP) T-Plate (~$240 AUD) via a medial sub-vastus approach. The T-plate was contoured and placed superior to the medial condyle. A combination of 4.5mm cortical, 5mm locking and/or 6.5mm cancellous screws were used, with oblique screw trajectories towards the distal lateral cortex of the lateral condyle. All extra-articular fractures and revision fixation cases were allowed to weight bear immediately. The primary outcome was union rate.

This technique was utilised on sixteen patients; 3 acute, 13 revisions; mean age 52 years (range 16-85), 81% male, 5 open fractures. The union rate was 100%, with a median time to union of 29 weeks (IQR 18-46). The mean follow-up was 15 months. There were two complications: a deep infection requiring two debridements and a prominent screw requiring removal. The mean range of motion was 1–108^o.

Supplemental medial plating of DFF with a Large Fragment LCP T-Plate is a feasible, safe, and economical option for both acute fixation and revisions. Further validation on a larger scale is warranted, along with considerations to developing a specific implant in line with these principles.

Aim

There are no studies in literature that analyze the effectiveness of closed-incisional negative pressure wound therapy (ciNPWT) in the treatment of bone and joint infections (BJI). The aim of the study was to evaluate the efficacy and the safety of the application of ciNPWT in the postsurgical wound management of patients with osteoarticular infections.

To determine whether pre-operative cessation of anticoagulant or antiplatelet medication is necessary for patients undergoing total shoulder arthroplasty (TSA) or reverse total shoulder arthroplasty (RTSA).

A prospectively maintained database was used to identify 213 consecutive patients treated with TSA or RTSA performed by a single surgeon across 3 centres. This cohort included 24 patients on an anticoagulant agent (warfarin, apixaban, rivaroxaban, dabigatran), 52 patients on an antiplatelet agent (aspirin, clopidogrel), and a control group of 137 patients not on anticoagulant or antiplatelet medication. Patients on anticoagulant or antiplatelet medications continued these agents peri-operatively. Outcomes included haemoglobin drop, intra-operative blood loss, operative time, transfusion requirements and post-operative complications.

The mean age of the cohort was 74.3 years (range 47 – 93) and 75 (35.2%) of the patients were male. TSA was performed in 63 cases and RTSA in 150 cases. The mean haemoglobin drop in the control group was 17.3 g/L, compared to 19.3 g/L in the anticoagulant group (p = 0.20) and 15.6 g/L in the anti-platelet group (p = 0.14). The mean intra-operative blood loss in the control group was 107.8 mL, compared to 143.0 mL in the anticoagulant group (p = 0.03) and 134.3 mL in the anti-platelet group (0.02). The mean operative time in the control group was 49.3 minutes, compared to 47.1 minutes in the anticoagulant group (p = 0.56) and 50.3 minutes in the anti-platelet group (p = 0.78). Post-operatively no patients developed a wound infection or haematoma requiring intervention. Three patients not on anticoagulant or antiplatelet medication developed pulmonary embolism.

Continuing anticoagulant or antiplatelet medication was associated with higher intra-operative blood loss, but produced no statistically significant differences in haemoglobin drop, operative time, transfusion requirements or post-operative complications. We now do not routinely stop any anticoagulant or antiplatelet medication for patients undergoing total shoulder arthroplasty.

The bone-patellar tendon-bone (BTB) autograft is associated with difficulty kneeling following anterior cruciate ligament (ACL) reconstruction, however it is unclear whether it results in a more painful or symptomatic knee when compared to the hamstring tendon autograft. This study aimed to identify the rate of significant knee pain and difficulty kneeling following primary ACL reconstruction and clarify whether graft type influences the risk of these complications.

Primary ACL reconstructions prospectively recorded in the New Zealand ACL Registry between April 2014 and November 2019 were analyzed. The Knee Injury and Osteoarthritis Outcome Score (KOOS) was analyzed to identify patients who reported significant knee pain, defined as a KOOS Pain subscale score of ≤72 points, and kneeling difficulty, defined as a patient who reported “severe” or “extreme” difficulty when they kneel. The rate of knee pain and kneeling difficulty was compared between graft types via univariate Chi-square test and multivariate binary logistic regression with adjustment for patient demographics.

4492 primary ACL reconstructions were analyzed. At 2-year follow-up, 9.3% of patients reported significant knee pain (420/4492) and 12.0% reported difficulty with kneeling (537/4492). Patients with a BTB autograft reported a higher rate of kneeling difficulty compared to patients with a hamstring tendon autograft (21.3% versus 9.4%, adjusted odds ratio = 3.12, p<0.001). There was no difference between graft types in the rate of significant knee pain (9.9% versus 9.2%, p = 0.49) or when comparing absolute values of the KOOS Pain (mean score for BTB = 88.7 versus 89.0, p = 0.37) and KOOS Symptoms subscales (mean score for BTB = 82.5 versus 82.1, p = 0.49).

The BTB autograft is a risk factor for post-operative kneeling difficulty, but it does not result in a more painful or symptomatic knee when compared to the hamstring tendon autograft.

Aim

Staphylococcus aureus (SA) can cause various infections and is associated with high morbidity and mortality rates of up to 40%. Antibiotic treatment often fails to eradicate SA infections even if the causative strain has been tested susceptible in vitro. The mechanisms leading to this persistence is still largely unknown. In our work, we to reveal SA interactions with host cells that allow SA to persist at the site of infection.

Hip and knee joint arthroplasty wait list has been getting outrageously long in South Africa with some tertiary hospital reporting more than 5 years of waiting time. This has been further compounded by covid 19 pandemic. There is plateau of ideas on how best to address the backlogs in high volume tertiary centers, with catchup list, out reach program, private partnership seeming unsustainable. We sought to look for sustainable solution to the problem and we looked not far but inside the system.

Excessive resident duty hours (RDH) are a recognized issue with implications for physician well-being and patient safety. A major component of the RDH concern is on-call duty. While considerable work has been done to reduce resident call workload, there is a paucity of research in optimizing resident call scheduling. Call coverage is scheduled manually rather than demand-based, which generally leads to over-scheduling to prevent a service gap. Machine learning (ML) has been widely applied in other industries to prevent such issues of a supply-demand mismatch. However, the healthcare field has been slow to adopt these innovations. As such, the aim of this study was to use ML models to 1) predict demand on orthopaedic surgery residents at a level I trauma centre and 2) identify variables key to demand prediction.

Daily surgical handover emails over an eight year (2012-2019) period at a level I trauma centre were collected. The following data was used to calculate demand: spine call coverage, date, and number of operating rooms (ORs), traumas, admissions and consults completed. Various ML models (linear, tree-based and neural networks) were trained to predict the workload, with their results compared to the current scheduling approach. Quality of models was determined by using the area under the receiver operator curve (AUC) and accuracy of the predictions. The top ten most important variables were extracted from the most successful model.

During training, the model with the highest AUC and accuracy was the multivariate adaptive regression splines (MARS) model, with an AUC of 0.78±0.03 and accuracy of 71.7%±3.1%. During testing, the model with the highest AUC and accuracy was the neural network model, with an AUC of 0.81 and accuracy of 73.7%. All models were better than the current approach, which had an AUC of 0.50 and accuracy of 50.1%. Key variables used by the neural network model were (descending order): spine call duty, year, weekday/weekend, month, and day of the week.

This was the first study attempting to use ML to predict the service demand on orthopaedic surgery residents at a major level I trauma centre. Multiple ML models were shown to be more appropriate and accurate at predicting the demand on surgical residents as compared to the current scheduling approach. Future work should look to incorporate predictive models with optimization strategies to match scheduling with demand in order to improve resident well being and patient care.

Aim

There are no definitive criteria for the definition of osteomyelitis in the hand and wrist and published case series are small. It remains a relatively uncommon, but difficult to treat problem. We present a series of 30 cases from 2016 to 2021 from a tertiary referral centre. We propose that the principles of thorough surgical debridement, dead space management, skeletal stabilisation and culture driven antibiotic therapy are the key to management of osteomyelitis in the hand and wrist. In addition, we show how these basic principles can be used for both functional and aesthetic impact for the wrist and digits with illustrated cases.

High energy pelvic injury poses a challenging setting for the treating surgeon. Often multiple injuries are associated, which makes the measurement of short- and long-term functional outcomes a difficult task. The purpose of this study was to determine the incidence of pelvic dysfunction and late impacts of high energy pelvic ring fractures on pelvic floor function in women, with respect to urinary, sexual and musculoskeletal function. This was compared to a similar cohort of women with lower limb fractures without pelvis involvement.

The data in our study was prospectively gathered between 2010 and 2013 on 229 adult females who sustained injury between 1998 and 2012. Besides demographic and operative variables, the scores of three validated health assessment tools were tabulated: King's Health Questionnaire (KHQ), Female Sexual Function Index (FSFI) and the Short Musculoskeletal Functional Assessment (SMFA). A multivariate regression analysis was done to compare groups.

The incidence of sexual dysfunction was 80.8% in the pelvis and 59.4% in the lower extremity group. A Wilcoxon rank sum test showed a significant difference in KHQ-score (p<0.01) with the pelvis group being worse. When adjusting for age, follow-up and Injury Severity Score this difference was not significant (p=0.28), as was for FSFI and SMFA score. The mean FSFI scores of both groups met the criteria for female sexual dysfunction (<26). Patients with a Tile C fracture have better FSFI scores (16.98) compared to Tile B fractures (10.12; p=0.02). Logistic regression predicting FSFI larger than 26.5 showed that older age and pelvic fractures have a higher likelihood having a form of sexual dysfunction.

Sexual dysfunction after lower extremity trauma is found in patients regardless of pelvic ring involvement. Urinary function is more impaired after pelvic injuries, but more data is needed to confirm this. Older age and pelvic fracture are predictors for sexual dysfunction in women. This study is important as it could help counsel patients on the likelihood of sexual dysfunction, something that is probably under-reported and recognized during our patient follow up.
