RESUMEN

INTRODUCTION: There is a paucity of published research on symptomatic venous thromboembolism (sVTE) after distal femur fractures (DFFs). This study aimed to explore the prevalence and risk factors of sVTE in DFFs. METHODS: We identified a total of 131 patients who underwent DFF surgeries without routine pharmacological thromboprophylaxis between October 2007 and November 2016. Cases of sVTE included symptomatic pulmonary embolism (sPE) and symptomatic deep vein thrombosis (sDVT). Patients with sVTE were compared to those without, and differences in demographics and fracture-related characteristics were explored. Multivariate logistic regression was used to eliminate confounding factors. RESULTS: Of the 131 patients, 20 (15.3%) had sVTE, of whom 16 (12.2%) had sDVT and six (4.6%) had sPE (two patients had both sPE and sDVT). Notably, 17 (85.0%) sVTE patients were aged ≥60 years, while only 62 (55.9%) non-sVTE patients were aged ≥60 years (P = 0.014). Fourteen (82.4%) patients with sVTE had body mass index (BMI) ≥25 kg/m2, while 49 (53.3%) patients without sVTE had BMI ≥25 kg/m2 (P = 0.032). Multivariate logistic regression demonstrated that age ≥60 years (adjusted odds ratio [OR] 5.05; P = 0.040) and BMI ≥25 kg/m2 (adjusted OR 3.92; P = 0.045) were independently associated with a higher risk of sVTE after DFF. CONCLUSION: The prevalence of sVTE in DFFs is high at 15.3%. Advanced age (≥60 years) and being overweight (BMI ≥25 kg/m2) were two independent risk factors for sVTE in DFFs. The use of routine pharmacological thromboprophylaxis should be considered as a preventative measure.

RESUMEN

INTRODUCTION: Paratenon preserving techniques to facilitate acute Achilles tendon rupture repair (AATR) functions by maintaining vascularity and biology for optimal healing response. Therefore, the purpose is to evaluate the outcomes following paratenon preserving repair of the midsubstance AATR. The hypothesis was that paratenon-preserving techniques demonstrate high return to play rates and low complication rates for the repair of the midsubstance AATR. MATERIALS AND METHODS: A systematic review of the PubMed, Embase, and the Cochrane Library databases was performed by two authors using specific search terms and eligibility criteria. The assessment of the evidence was two-fold: level and quality of evidence. A meta-analysis of proportions for the various complication rates was performed using the restricted maximum likelihood method following the Freeman-Tukey double-arcsine transformation. Fixed effects models were employed if I2 < 25% (low heterogeneity), and random effects models were employed if I2 ≥ 25% (moderate to high heterogeneity). RESULTS: The pooled return to play rate was 90.3%. The pooled rerupture rate as reported was 0.9% (best-case scenario 0.8% and worst-case scenario 6.8%). No meaningful subgroup analysis for rerupture rates could be performed based on the meta-regression. The pooled complication rate other than reruptures was 4.8%. The pooled infection rates were 0.3%, DVT rates were 1.6%, and sural nerve injury rates were 0.3%. CONCLUSIONS: Paratenon preserving techniques that are minimally invasive in nature demonstrated safe and favorable outcomes with high return to play rates and low complication rates for the repair of the midsubstance AATR.

RESUMEN

➤ The concept of anteromedial cortical support (AMCS) serves as valuable guidance for the intraoperative reduction of trochanteric hip fractures.➤ Positive medial cortical support (MCS) and positive or neutral anterior cortical support (ACS) are desirable. Some evidence has suggested that positive MCS is potentially superior to neutral MCS.➤ Experimental studies underscore the vital importance of the anteromedial wall and reveal why positive MCS potentially outperforms neutral MCS.➤ Incorporating the AMCS concept, the Chang reduction quality criteria (CRQC) are a reliable alternative approach to evaluate the reduction quality of trochanteric hip fractures.

RESUMEN

We present a unique case of a 59-year-old shipyard worker who sustained an avulsion fracture of the tibialis anterior tendon, concurrently with a comminuted fracture at the base of the first metatarsal. This is the first reported case highlighting this concomitant presentation, which underlines the possibility of avulsion fractures accompanying comminuted fractures. Importantly, such avulsion fractures could lead to skin tenting and potential necrosis, necessitating early identification and prompt intervention. The patient underwent successful surgical intervention and displayed good functional restoration 15 months postoperatively.

RESUMEN

Lateral ankle sprain is a common injury with a substantial negative impact on physical function, quality of life and health economic burden. Chronic lateral ankle instability (CLAI) as a sequela of lateral ankle sprain can lead to the development of posttraumatic ankle osteoarthritis in the long term. In this article, we explore the epidemiology, burden and definition of CLAI for the appropriate clinical assessment and imaging evaluation of patients with lateral ankle sprain and CLAI. Following that, recent advances and evidence on management of CLAI is critically distilled and summarized.

RESUMEN

OBJECTIVES: To conduct a systematic review and meta-analysis of prevalence of cardiovascular-related morbidity and mortality in patients with diabetic foot ulcers (DFU), as well as compare risks of cardiovascular-related morbidity and mortality between diabetic patients with and without DFU. METHODS: A systematic search was conducted on Medline, Embase, and Cochrane databases for randomized controlled trials and observational studies which explored the association between DFU and cardiovascular-related morbidity & mortality, or compared differences in hazard ratios of cardiovascular diseases between diabetics with and without DFU. Frequentist, pairwise meta-analysis was performed on studies with two comparator arms, whereas single-arm studies reporting pooled incidences of cardiovascular-related mortality and morbidity were calculated based on exact binomial distributions. A random-effect meta-analysis model was used with heterogenicity of studies assessed using I2, τ2, and χ2 statistics. RESULTS: 10 studies were identified and included in the systematic review & meta-analysis of 8602 patients. DFU was consistently found to have significant association with cardiovascular-related morbidity and mortality, with pooled prevalences of all cause cardiovascular-related morbidity (37.1%), IHD (44.7%), CHF (25.1%), CAD (11.7%), and CVA (10.9%), and all cause cardiovascular-related mortality (14.6%), fatal IHD (6.2%), fatal CHF (3.67%), fatal CAD (7.92%), and fatal CVA (1.99%). Diabetic patients with DFU were found to have significantly increased risk of IHD (RR 1.25), CVA (RR 2.03), and all-cause cardiovascular-related mortality (RR 2.59) compared to those without DFU. CONCLUSIONS: The presence of DFU is associated with major adverse cardiac events. The alarming rates of cardiovascular-related morbidity and mortality in DFU patients highlight its potential role as a marker of cardiovascular complications and should prompt early clinical investigation and management.

RESUMEN

Background: Suture button fixation is frequently used to stabilize the distal tibiofibular syndesmosis in athletes sustaining an isolated ligamentous syndesmosis injury. Purpose: To report on a series of periprosthetic fibula fractures adjacent to the lateral suture button after a subsequent unrelated ankle injury or progressive stress injury after initial ankle syndesmosis stabilization using the knotless TightRope (Arthrex). Study Design: Case series; Level of evidence, 4. Methods: Eight elite athletes with periprosthetic fibula fractures and stress injuries around the lateral suture buttons were evaluated. In all athletes, the knotless TightRope had been used to stabilize an isolated ligamentous ankle syndesmotic injury, after which all patients recovered and returned to professional sports at their preinjury level. The athletes subsequently developed an acute fibula fracture or a fibula stress fracture related to the 3.7-mm drill hole in the fibula adjacent to the lateral suture buttons after a mean of 14.1 months (range, 5-29 months). The management of these complications was analyzed. Results: Five athletes sustained a periprosthetic fibula fracture in the form of undisplaced spiral Weber B injuries after a subsequent, unrelated injury. Poor healing response was noted with initial nonoperative treatment for the first 2 athletes, and surgical intervention was performed with successful union of the fracture and return to sports. The subsequent 3 athletes had early surgery with uneventful recovery. Another 3 athletes developed stress injuries adjacent to the fibula suture button without a history of acute trauma. In 2 of the 3 athletes, the position of lateral suture buttons was in the anterior third of the fibula. Initial nonoperative management yielded poor healing response, and subsequent surgical intervention was required to enable healing and return to sports. Conclusion: Nonoperative management of fractures adjacent to the fibula suture button of a knotless TightRope may lead to a delay in union. Therefore, early surgical intervention should be considered in elite athletes, whose return-to-sports time is critical. Care is needed to ensure that the fibula hole for the suture button is centrally located because the eccentric placement of the fibula hole in the anterior third of the fibula may contribute to the development of a stress reaction or stress fracture. Surgical intervention for a periprosthetic fibula stress fracture leads to satisfactory resolution of symptoms.

RESUMEN

PURPOSE: Differential elongation of the gastrocnemius after Achilles tendon rupture (ATR) may compromise the ability of athletes to return to competition. Recognition of this differential elongation of the gastrocnemius relative to the soleus is vital to treat patients with weakness in push-off. This paper describes a novel technique performed for selective shortening of the gastrocnemius to treat push-off weakness. METHODS: Three patients with differential proximal retraction of the gastrocnemius greater than 20 mm after treatment for ATR with inability to run and jump underwent surgical correction with this novel technique and were followed-up for 2 years. A novel selective shortening of the gastrocnemius with autologous hamstring graft was performed in these patients. The Achilles Tendon Total Rupture Score (ATRS) and American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score were recorded preoperatively and at the final follow-up. RESULTS: All three patients were able to return to running and jumping at final follow-up. The ATRS improved significantly in the strength, fatigue, running and jumping domains but there appeared to be a less notable improvement in activities of daily living domain. The AOFAS score showed improvement with the greatest margin in the domain of activity limitation. CONCLUSION: This procedure is the first described selective shortening method of the gastrocnemius tendons after differential elongation following ATR. It is a safe and reliable technique providing improved ATRS and AOFAS scores in three patients who were all able to return to running and jumping sports at 2-year follow-up. LEVEL OF EVIDENCE: IV.

RESUMEN

BACKGROUND: In vivo evaluation of ankle joint biomechanics is key to investigating the effect of injuries on the mechanics of the joint and evaluating the effectiveness of treatments. The objectives of this study were to 1) investigate the kinematics and contact strains of the ankle joint and 2) to investigate the correlation between the tibiotalar joint contact strains and the prevalence of osteochondral lesions of the talus distribution. METHODS: Eight healthy human ankle joints were subjected to compressive load and 3 T MRIs were obtained before and after applying load. The MR images in combination with digital volume correlation enabled non-invasive measurement of ankle joint kinematics and tibiotalar joint contact strains in three dimensions. FINDINGS: The total translation of the calcaneus was smaller (0.48 ± 0.15 mm, p < 0.05) than the distal tibia (0.93 ± 0.16 mm) and the talus (1.03 ± 0.26 mm). These movements can produce compressive and shear joint contact strains (approaching 9%), which can cause development of lesions on joints. 87.5% of peak tensile, compressive, and shear strains in the tibiotalar joint took place in the medial and lateral zones. INTERPRETATION: The findings suggested that ankle bones translate independently from each other, and in some cases in opposite directions. These findings help explain the distribution of osteochondral lesions of the talus which have previously been observed to be in medial and lateral regions of the talar dome in 90% of cases. They also provide a reason for the central region of talar dome being less susceptible to developing osteochondral lesions.

RESUMEN

Lateral ankle sprain (LAS) is not as simple as it was believed to be as it has substantial negative impacts on the active sporting population. The negative impact on physical function, quality of life (QoL) and economic burden is significant with increased risk of reinjury, development of chronic lateral ankle instability and posttraumatic ankle osteoarthritis resulting in functional deficits, decreased QoL and chronic disabilities. Economic burden from a societal perspective demonstrated notably higher indirect costs from productivity loss. Preventative interventions with early surgery for a selective cohort of active sporting population may be considered to mitigate morbidities associated with LAS.

RESUMEN

BACKGROUND: The first ray plays a vital role in the normal function of the foot and the gait cycle where in its absence can lead to abnormal changes in weight distribution to the residual first metatarsal stump and lesser metatarsals with predisposition to developing lesser toe deformities reulcerations and reamputations particularly in diabetic patients. This study aims to characterise the outcomes after first ray amputation and its associated risk factors with focus on the impact of residual first metatarsal length. METHODS: All diabetic patients with first ray amputations from January 2012 to December 2016 were reviewed. Residual first metatarsal length was measured using postoperative radiographs. Risk factors for outcomes such as readmission, reulceration and/or reamputation, transfer ulceration and/or amputation of lesser toes, proximal amputations, ulcer-free duration (UFD) and mortality were analysed using bivariate logistic/linear regression followed by multiple logistic/linear regression models adjusting for confounding factors. RESULTS: Among 89 patients with first ray amputations, 65.3 % needed readmission for further treatment. Although only 10.1 % had reulceration at the first ray which all led to reamputation, there were 56.2 % with transfer ulceration and 40.4 % with transfer amputation of the lesser toes in this cohort. The prevalence of transmetatarsal amputation was 18 % and proximal amputations at 12.4 % while the average UFD was 27 months. Mortality rate was 31.5 % with an average of 3-year survival. Preservation of the first metatarsal length via metatarsophalangeal joint disarticulation independently reduced likelihood of readmissions and residual metatarsal length of > one third when compared to < one third after first ray amputations had lower likelihood of transfer amputation of lesser toes. CONCLUSION: First ray amputation in diabetic patients leads to significant morbidities and mortality. Preservation of the residual first metatarsal length independently reduced the likelihood of readmissions and transfer amputation to the lesser toes.

RESUMEN

BACKGROUND: We aim to review and describe the proportion of patients with co-existing gout amongst patients with surgical treated septic arthritis, characterize their clinical presentation, outcomes and complications compared to patients with native joint septic arthritis. METHODS: Sixty-one patients with surgically treated primary joint septic arthritis were identified from the period of January 2011 to December 2016. There were 13 (21.3%) patients with co-existing septic arthritis and crystal proven gout. Pertinent details such as demographics, comorbidities, clinical features on presentation, infection markers, number of surgeries, length of stay (LOS) in general and individual LOS in supportive care units, limb amputations, readmissions and mortality were reviewed. Multiple linear and logistic regression models were used to control for confounders during analysis. RESULTS: The average age of patients was 60.8 years (range: 23-87 years). The patients with gout are associated with comorbidities such as being hypertensive, hyperlipidemia and renal impaired. They tend to present with ankle joint involvement (46.2% vs 8.3%; p = 0.004) while septic arthritis patients without gout tend to present with knee joint involvement (75% vs 46.2%; p = 0.046). In terms of complications, up to two thirds of them require supportive care in the High Dependency Unit and/or Intensive Care Unit during treatment (61.5% vs 29.2%; p = 0.031) and having gout with septic arthritis independently predicted a significant increase in LOS by an additional 12.6 days on average (95% CI: 2.11 - 23.03; p = 0.019). They are also more likely to end up with limb amputation (23.1% vs 0%; p = 0.008) on univariate analysis. CONCLUSION: Gout accompanying septic arthritis in the same joint is potentially associated with major systemic and joint related sequela, complications in terms of prolonged hospital stay, need for complex care and risk for limb amputation. Our findings further indicate the value and need for well-designed prospective controlled cohort studies to explore the relationship between gout and septic arthritis.

RESUMEN

INTRODUCTION: This study aims primarily to characterize the sequelae and morbidity associated with tibial pilon injuries from the patients' perspectives in terms of multiple surgical interventions, duration of hospital stay, downtime from work, loss of productivity and impact on patients' lives. The secondary aim is to review the associated risk factors for these morbidities. MATERIALS AND METHODS: All patients with surgically treated tibial pilon fractures from 1st July 2007 to 30th June 2017 were included. The morbidities reviewed focused on delay to surgery, numbers of surgeries, limb amputation, length of stay (LOS), readmissions, duration of medical leave (ML), follow-up and number of outpatient visits. RESULTS: There were 102 patients included in the review and up to 70% of them had an average 7 days delay to definitive surgery. They also required an average hospital LOS of at least 2 weeks extending up to 3 more weeks if soft tissue reconstruction was necessitated. Up to a third of patients were readmitted with 15% of them needing further treatment. These patients required a notable period of downtime from work as shown in the long ML (mean 152.6 days [S.D. = 110.7]). Multiple conditional regression models showed AO/OTA classification (B and C) and open fracture as independent predictors of delay to surgery. Predictors for increased LOS were high velocity mechanism of injury at 4 days longer and patients who needed soft tissue reconstruction at 21 days longer. In terms of downtime from work, only work injury has been identified as an independent predictor of ML at 88.5 days longer. CONCLUSION: Tibial pilon fractures leads to significant morbidities with profound negative impact on patients' lives in terms of multiple surgical interventions required, prolonged hospital stay, need for readmissions and prolonged downtime from work. These morbidities from patients' perspective should be emphasized to patients and employers to manage their expectations and potential limitations.

RESUMEN

PURPOSE: Lateral ligament ankle sprains are common and the anatomy on imaging studies is vital for accurate diagnosis. The lateral fibulotalocalcaneal ligament (LFTCL) complex consists of the inferior fascicle of the anterior talofibular ligament (ATFL) which is connected by arciform fibres with the calcaneofibular ligament (CFL). The superior fascicle of ATFL is an independent structure that should be assessed individually. MRI evaluation of these distinct fascicles and the arciform fibres has not been described. The aim of this study is to identify the anatomical relationship of these components of the LFTCL complex in healthy individuals on MRI. METHODS: Thirty ankles from healthy volunteers were imaged using 3D volumetric MRI. The ATFL fascicles and size were evaluated. Presence of arciform fibres connecting the inferior ATFL fascicle and CFL to form the LFTCL complex and anatomical relationship around the lateral ligament complex were assessed. RESULTS: Both the superior and inferior ATFL fascicles were observed in 26 (86.7%) ankles. The superior ATFL fascicle was significantly larger in all specimens (39% longer and 80.7% wider). For the specimens with a single fascicle, this was similar in size to the superior fascicle observed in the other 26 specimens. These measurements were not affected by age or gender. Arciform fibres of the LFTCL complex were identified in 22 (84.6%) specimens with two ATFL fascicles and three (75%) ankles with a single ATFL fascicle. Connecting fibres from the ATFL to PTFL were observed in 19 (63.3%) ankles while connections between the CFL and PTFL were identified in 21 (70%) ankles. Five ankles had a perforating artery visualized in the intervening space between the superior and inferior ATFL fascicles (a branch of the lateral tarsal artery of the dorsalis pedis artery). CONCLUSION: Two distinct ATFL fascicles may be identified in the majority of ankles on MRI. Isolated injury to the superior fascicle identified on MRI may be useful when diagnosing patients presenting with symptoms of subtle instability without overt ankle laxity on clinical examination. The current study is the first to identify the arciform fibres of the LFTCL complex supporting isolated ATFL repair in the presence of intact LFTCL complex. LEVEL OF EVIDENCE: Level III.
