Background: Injuries to ankle joint consist 12% of visits to emergency departments. In spite of the common occurrence of ankle sprain, syndesmosis injuries are rare, but very debilitating and frequently misdiagnosed. Methods: Among 100 patients with ankle sprain we evaluated the incidence of syndesmosis sprain by MRI of the ankle. Adults who had acute ankle sprain with no fracture and examined on the same day that injury had took place were being included in the survey. Results: Out of 100 patients with ankle injury, four had syndesmosis sprain. Three patients had partial tear of syndesmotic complex and one had complete tear. All injuries occurred in sports except one which had happened in an accident, and two of the patients were athletes. Anterior inferior tibiofibular ligament was the most common ruptured ligament. Conclusions: We reported a four-percent incidence of this injury. Our high rate of this injury emphasized on the fact that all suspicious cases should go under more accurate investigation not to miss this diagnosis

The unresolved ankle sprain is one of the most common referrals to a specialist orthopaedic foot & ankle surgeon. These injuries occur in sports people as well as workers, and frequently cause prolonged sporting inactivity or time off work. The unresolved ankle sprain can be defined as that injury which does not resolve with appropriate conservative treatment within six weeks. The pathology causing an ankle sprain to be unresolved can involve soft tissue or bony structures. Thorough clinical and radiological assessment is necessary to secure the diagnosis, institute effective surgical treatment and counsel the patient accurately with regards to prognosis for the injury. This paper discusses the differential diagnosis & surgery in order to resolve prolonged disability after the common ankle sprain

Purpose: The aim of this paper is to present a new surgical method for the reconstruction of the recurrent sprain of the ankle. Material – Methods: From 1980 until 1997, 17 patients 3 females and 14 males, average age 25.53 (19 – 44) underwent surgery suffering recurrent sprain of the ankle. In 11 patients the right ankle was involved and in 6 patients the left ankle. The cause of the injury was: athletic activities in 9 cases, weekend activities in 7 cases and daily activities in 1 case. The patients were suffering from ankle instability 4–15 years prior the operation. All the patients underwent reconstructive surgery of the anterolateral elements (capsule and ligaments) according to senior author’s method. This included shortening of the anterolateral elements, capsule and ligaments, overlaping the anterolateral part over the anterolateral one in such a way, that the anterior drawer and varus tests were negative with the patient under anaesthesia. Results: The follow up is 2–12 years. A patient underwent for a second time surgery, because of a new injury. In 2 patients early signs of ankle osteoarthritis. In the rest of them, restoration of the function of the ankle joint was excellent, obtaining full activities 3 months postperatively. Conclusion: This surgical method for the reconstruction of the recurrent sprain of the ankle is considered satisfactory and when indicated allows young patients and athletes to participate in a rather short period of time, in their previous level of activities

Purpose: Pain occasionally develops in the posterior tibial tendon after chronic sprains, whose pathology is not known yet. We inserted an endoscope (tendoscope) into the tendon sheath of the tibialis posterior and treated based on the observation of its pathology. Subjects and methods: Subjects were patients who had complained pain in the posterior tibial tendon after ankle sprain. The interval from the injury to the tendo-scope ranged from one month to one year and 8 months with an average of 9 months. There were 18 patients (11males, 7females). The age ranged from 18 to 33 years with an average of 24 years. For initial treatment, cast fixation, and orthoses were employed in 10 patients. Other 8 patients were left with bandage alone. For these patients, a 2.4mm-diameter endoscope was inserted into the tendon sheath. Results: Synovia proliferation was found in all the cases, and vicula in the tendon sheath disappeared. Synovia proliferation was found in all patients and erosion of the tendon was observed in 8 patients. In other 3 patients, injured sliding floor of the posterior tibial tendon was found. For treatment, synovectomy and smoothing of the sliding floor were performed. All the patients had improvement of pain and returned to sports with the former level. Discussion: It has been known that, in some cases, pain emerges in the posterior tibial tendon after ankle sprain. Its pathology has remained unknown. It is suggested that injuries in the tendon sheath of the tibialis posterior, sliding floor of the tendon, and deltoid ligament associated with the sprain may have caused inflammations, which has developed synovia proliferation. It is thought posterior tibial tendon is often injured after ankle sprain

1. Partial diastasis of the tibio-fibular syndesmosis is believed to be common, but it is often overlooked as a cause of recurrent sprains of the ankle. 2. The treatment of recurrent sprains of the ankle by stabilising the inferior tibio-fibular joint with a lag screw is described. The method has been used in seventy-five patients aged between sixteen and sixty-five years. The longest follow-up has been six years

This study assessed the effect of litigation on the long-term outcome and recovery of ankle inversion injuries. 167 patients from an accident and emergency database were contacted by telephone. Thirty participants were litigating and these candidates were randomly matched with 30 non-litigating patients with respect to mechanism of injury. Each group had 27 patients with ankle sprains because of falls/trips and 3 after road traffic accidents. Radiographs when available of each participant were examined and the degree of soft tissue swelling over the lateral malleolus was assessed. 76.6% of litigants reported incomplete recovery compared to 26.7% of non-litigants. The median period of sleep disturbance, swelling, limping and non-weight-bearing was 1.5 days, 2.0 weeks, 2.0 weeks and 1.0 weeks for the non-litigants. This compares to 3.5 days, 10.0 weeks, 8.0 weeks and 8.0 weeks for the litigants using the same variables (p< 0.0001 in all cases). Where ankle radiographs had been taken swelling was equal in each group (9.0mm over lateral malleolus (30% of litigants incorrectly suggested an ankle x-ray had been taken, when it had not)). The majority of litigants (65%) thought that physiotherapy would not be beneficial in rehabilitating their ankle (35% non-litigants). It appears that litigation has a negative effect on the outcome and recovery of ankle sprains

Sprain of the pisiform triquetral joint is a definite clinical entity. It presents as a "tenosynovitis" of the flexor carpi ulnaris muscle from which it can be distinguished by the tests described. The disability in most cases is such that operation is justifiable. Fusion of the pisiform-triquetral joint is preferred to excision of the pisiform because it restores stability to the wrist with the least disturbance to related structures

Purpose of the study: High-energy varus or valgus ankle trauma causes severe injury to the capsule and ligaments. We describe a presentation associating massive tears of the lateral/medial collateral ligaments with a transversal wound of the corresponding malleolus. This wound results from excessive tension on the skin cause by the major varus/valgus. We have defined this injury as an open and severe ankle sprain (OSAS). Material and method: This was a retrospective analysis. We search the databases of three participating centres using the corresponding diagnostic and therapeutic codes from January 2005 to January 2009. The identified files were screened to select patients with OSAS. Results: There were 11 cases of OSAS. Eight involved the lateral side of the ankle and three the medial side. Mean age was 41 years (range 21–45). All patients were victims of a high-energy trauma (five motorcycle accidents) and four patients had fallen from a high point. Associated injuries were tendon section (n=3), section of the deep fibular nerve (n=2), and section of the anterior tibial artery (n=1). Pneumarthrosis was the only visible anomaly on the plain x-rays of seven ankles. Diagnosis was confirmed preoperatively in all cases clinically with varus-valgus stress manoeuvres. Conclusion: OSAS is a rare misleading injury. Confusion with a common wound is possible. The risk is to miss acute instability and thus its treatment. The diagnosis should be proposed for all transversal wounds without contusion over the malleolus with normal x-rays

Purpose of the study: Appropriate management of chronic sprains of the scapholunate joint remains a subject of debate. Different surgical techniques have been proposed, from partial arthrodesis of the carpus to ligamentoplasty. We opted for scaphocapitatum arthrodesis. The purpose of this report was to assess clinical and radiological outcome. Material and methods: From 1997 to 2001, 13 arthrodeses (13 patients) were performed for this indication. The procedure involved two screws (n=11), one screw and stapling (n=1), and stapling alone (n=1). A free autologous graft was used in all cases. Mean patient age was 40 years (12 males and one female). These patients were victims of sports accidents (n=8) or occupational accidents (n=5). Mean follow-up was 26 months (range 24–31 months). Variables noted were joint mobility, pain, grasp force and pinch force. Wrist x-rays were used to measure the height of the carpus and the radio-lunate angle. Results: A 31% loss in the radial inclination was noted as as a 14.5% loss in the ulnar inclination. Dorsal flexion of the wrist declined from 60° to 48°, palmar flexion from 47° to 28°. Stiffness mainly involved the radial inclination and palmar flexion. Grasp and Pinch forces improved (125° on average). All patients excep one presented residual pain. Six patients complained of pain only for efforts and six presented invalidating pain. Only seven patients were able to resume their occupational activity. There were three cases of nonunion which required revision to achieve final bone healing (poor outcome). Carpal height improved (0.47±0.54). The mean radiolunate angle at last follow-up was 11°. DISI persisted in only one wrist. Discussion: This technique reduced wrist mobility. For all patients, the dorsal approach to the wrist produced inevitable stiffness. Radial inclination declines due to the intracarpal fusion. This arthrodesis enabled restitution of the carpal height and partially corrected for the DISI. This operation did not provide pain relief but did not alter the carpal x-ray. We raise the question of the pertinence of associating this type of arthrodesis with total denervation of the wrist

Injury to the perforating branch of the peroneal artery has not been reported previously as a cause of acute compartment syndrome following soft-tissue injury to the ankle. We describe the case of a 23-year-old male who sustained such an injury resulting in an acute compartment syndrome. In a review of the literature, we could find only five previous cases, all of which gave rise to a false aneurysm which was detected after the acute event.

A consecutive series of 100 cases of wrist injury, other than those referred with a radial fracture, have been reviewed to determine the incidence of acute scapholunate instability; a "clenched fist" radiograph was used in addition to the routine scaphoid views. Of 19 patients with an increase in the scapholunate gap, five were eventually considered to have significant scapholunate instability, two in association with Colles' fractures. Injuries producing significant ligamentous damage and carpal instability may be as common as scaphoid fractures. They require special consideration in diagnosis and management.

Aims. The aim of this systematic review and meta-analysis was to gather epidemiological information on selected musculoskeletal injuries and to provide pooled injury-specific incidence rates. Methods. PubMed (National Library of Medicine) and Scopus (Elsevier) databases were searched. Articles were eligible for inclusion if they reported incidence rate (or count with population at risk), contained data on adult population, and were written in English language. The number of cases and population at risk were collected, and the pooled incidence rates (per 100,000 person-years) with 95% confidence intervals (CIs) were calculated by using either a fixed or random effects model. Results. The screening of titles yielded 206 articles eligible for inclusion in the study. Of these, 173 (84%) articles provided sufficient information to be included in the pooled incidence rates. Incidences of fractures were investigated in 154 studies, and the most common fractures in the whole adult population based on the pooled incidence rates were distal radius fractures (212.0, 95% CI 178.1 to 252.4 per 100,000 person-years), finger fractures (117.1, 95% CI 105.3 to 130.2 per 100,000 person-years), and hip fractures (112.9, 95% CI 82.2 to 154.9 per 100,000 person-years). The most common sprains and dislocations were ankle sprains (429.4, 95% CI 243.0 to 759.0 per 100,000 person-years) and first-time patellar dislocations (32.8, 95% CI 21.6 to 49.7 per 100,000 person-years). The most common injuries were anterior cruciate ligament (17.5, 95% CI 6.0 to 50.2 per 100,000 person-years) and Achilles (13.7, 95% CI 9.6 to 19.5 per 100,000 person-years) ruptures. Conclusion. The presented pooled incidence estimates serve as important references in assessing the global economic and social burden of musculoskeletal injuries.

There is a disparity in sport-related injuries between sexes, with females sustaining non-contact musculoskeletal injuries at a higher rate. Anterior cruciate ligament ruptures are between two and eight times more common than in males, and females also have a higher incidence of ankle sprains, patellofemoral pain, and bone stress injuries. The sequelae of such injuries can be devastating to an athlete, resulting in time out of sport, surgery, and the early onset of osteoarthritis. It is important to identify the causes of this disparity and introduce prevention programmes to reduce the incidence of these injuries. A natural difference reflects the effect of reproductive hormones in females, which have receptors in certain musculoskeletal tissues. Relaxin increases ligamentous laxity. Oestrogen decreases the synthesis of collagen and progesterone does the opposite. Insufficient diet and intensive training can lead to menstrual irregularities, which are common in female athletes and result in injury, whereas oral contraception may have a protective effect against certain injuries. It is important for coaches, physiotherapists, nutritionists, doctors, and athletes to be aware of these issues and to implement preventive measures. This annotation explores the relationship between the menstrual cycle and orthopaedic sports injuries in pre-menopausal females, and proposes recommendations to mitigate the risk of sustaining these injuries.

The incisura fibularis (IF) provides intrinsic stability to the ankle joint complex by interlocking the distal tibia and fibula. Despite a high frequency of ligamentous ankle injuries, scant attention has been given to the morphology of the IF morphology incisura fibularis in the onset and development of these lesions. Therefore, we systematically reviewed the relation between ligamentous ankle disorders and the morphometrics of the IF. A systematic literature search was conducted on following databases: PubMed, Embase and Web of Science. Search terms consisted of ‘ankle trauma’, ‘ankle injury’, ‘ankle sprain’, ‘ankle fracture’, ‘tibiofibular’, ‘fibular notch’, ‘fibular incisura’, ‘incisura fibularis’, ‘morphometric analysis’, ‘ankle syndesmosis’, ‘syndesmotic stability’. The evaluation instrument developed by Hawker et al. was used to assess the quality of the selected studies. This protocol was performed according to the PRISMA guidelines and is registered on PROSPERO (CRD42021282862). Nineteen studies were included and consisted of prospective cohort (n=1), retrospective comparative (n=10), and observational (n=8) study design. Comparative studies have found certain morphological characteristics in patients with ankle instability. Several studies (n=5) have correlated a shallow IF depth with a higher incidence of ankle injury. A significant difference has also been found concerning the incisura height and angle (n=3): a shorter incisura and more obtuse angle have been noted in patients with ankle sprains. The mean Hawker score was 28 out of 36 (range=24-31). A shallower IF is associated with ligamentous ankle lesions and might be due to a lower osseous resistance against tibiofibular displacement. However, these results should be interpreted in light of moderate methodological quality and should always be correlated with clinical findings. Further prospective studies are needed to further assess the relation between the incisura morphometrics and ligamentous disorders of the ankle joint. Keywords: ankle instability, ankle injury, incisura fibularis, fibular notch, tibiofibular morphometrics, ankle syndesmosis

Ligament integrity is directly associated with ankle stability. Nearly 40% of ankle sprains result in chronic ankle instability, affecting biomechanics and potentially causing osteoarthritis. Ligament replacement could restore stability and avoid this degenerative pathway, but a greater understanding of ankle ligament behaviour is required. Additionally, autograft or allograft use is limited by donor-site morbidity and inflammatory responses respectively. Decellularised porcine grafts could address this, by removing cellular material to prevent acute immune responses, while preserving mechanical properties. This project will characterise commonly injured ankle ligaments and damage mechanisms, identify ligament reconstruction requirements, and investigate the potential of decellularised porcine grafts as a replacement material. Several porcine tendons were evaluated to identify suitable candidates for decellularisation. The viscoelastic properties of native tissues were assessed using dynamic mechanical analysis (DMA), followed by ramp to ‘sub-rupture’ at 1% strain/s, and further DMA. Multiple samples (n=5) were taken along the graft to assess variation along the tendon. When identifying suitable porcine tendons, a lack of literature on human ankle ligaments was identified. Inconsistencies in measurement methods and properties reported makes comparison between studies difficult. Preliminary testing on porcine tendons suggested there is little variation in viscoelastic properties along the length of tendon. Testing also suggested strain rates of 1%/s sub-rupture was not large enough to affect viscoelastic properties (no changes in storage or loss moduli or tanẟ). Further testing is underway to improve upon low initial sample numbers and confirm these results, with varying strain rates to identify suitable sub-rupture sprain conditions. This work highlights need for new data on human ankle ligaments to address knowledge gaps and identify suitable replacement materials. Future work will generate this data and decellularise porcine tendons of similar dimensions. Collagen damage will be investigated using histology and lightsheet microscopy, and viscoelastic changes through DMA

Acute lateral ankle sprain accounts for 85% of sprains. The lateral sprain is associated with other ligament injuries e.g. medial and syndesmosis sprain. Long-term, approximately 20% of acute lateral sprains develop into chronic lateral ankle instability (CLAI) which includes persistent pain, and recurring ankle sprains. This study evaluated the grade of an ankle ligament injury by ultrasonography (US) and compared the findings to the outcome of patient-reported questionnaires. 48 subjects (18–40 years) diagnosed with an ankle sprain attended a clinical and US examination of ankle ligaments within two weeks after the sprain. Evaluation was done by US of acute lateral ligament injuries (ATFL, CFL), syndesmosis injury (AiTFL), and medial injury (dPT, TCt) only in participants with the positive clinical signs of medial injury. Participants were then mailed a questionnaire (PROMQ) every third month for a year. 29 women and 19 men participated with a mean age at 26.50 years. One-year follow-ups need to be analyzed further for final results. Temporary results include data based on the initial 26 patients: Two clinical signs statistically correlated. Multiple logistic regression analysis confirmed the results. Positive palpated tenderness AiTFL predicted with partial ruptured ATFL and reported pain during active plantar flexion of ankle predicted with normal CFL confirmed by the US. Patients with partial rupture of ATFL presented with tenderness at AiTFL point. Patients presenting with intact CFL reported pain during active plantar flexion. Compared to the US findings, the overall examinations were inconclusive in predicting ATFL, CFL, AiTFL, and medial ligament injuries

Ankle sprains are common athletic injuries, with a peak lifetime incidence between the ages of 15 and 19 years, especially in young males. However, an unclear history, an imprecise physical exam, and unhelpful radiographies lead to frequent misdiagnosis of paediatric ankle traumas, and subsequently, inappropriate treatment. Improper management may lead to residual pain, instability, slower return to physical activity, and long-term degenerative changes. The purpose of this study was to evaluate the initial management and treatment of acute paediatric ankle sprains at our center, a tertiary care paediatric hospital. Our hypothesis was that the initial diagnosis is often incorrect, and treatment varies considerably amongst orthopaedic surgeons. We conducted a retrospective study of all cases of ankle sprains and Salter-Harris one (SH1) fractures referred to our orthopaedic surgery service between May and August 2014. Exclusion criteria included ankle fractures other than SH1 types, and cases where treatment was initially undertaken elsewhere before referral to our service. Patients were evaluated on a clinical and radiographic basis. Primary outcome was the difference between initial and final diagnosis. Secondary outcome was variation in immobilisation duration for each diagnosis. The main variables we considered were age, sex, mechanism of trauma, referral delay, patient symptoms, physical exam findings, radiographic findings, type and duration of immobilisation, prescription of any medication, and referral to physical therapy. A total of 3047 patients were reviewed and 31 cases matched our inclusion criteria, comprised of 17 girls and 14 boys, with a mean age of 10.4 years. Patients were seen at a mean of 10.3 days after injury. Initial diagnosis was SH1 fracture in 20 cases, acute ankle sprain in 8 cases, and uncertain in 3 cases. Final diagnosis was SH1 fracture in 11 cases, acute ankle sprain in 13 cases, uncertain in 5 cases, and other in 3 cases. During follow up, 48.5% of cases saw a change in diagnosis. Forty five percent (9/20) of cases initially diagnosed as SH1 fractures proved to be incorrect, with 55.5% (5/9) of these being ultimately diagnosed as acute ankle sprains. Amongst cases initially diagnosed as acute ankle sprains, 37.5% (3/8) received a different final diagnosis. Duration of immobilisation was significantly different between acute ankle sprain and SH1 fracture groups, with an average of 17.3 days and 26.1 days, respectively. Physical therapy was prescribed to 33.3% of acute ankle sprains and 9.1% of SH1 fractures. Initial distinction between acute ankle sprains and SH1 fractures can be difficult in paediatric ankle trauma. Case management and specific treatments vary considerably, as there is neither an evaluation algorithm nor consensus on treatment of these paediatric pathologies. This study reinforces the need to develop a systematic diagnostic and treatment protocol for paediatric ankle sprains

Ankle sprains are common injuries. Most of them involve the lateral ligament complex. 20–40%% of these injuries will go onto develop symptomatic chronic lateral instability (CLI) and require surgical intervention. The gold standard surgical treatment remains the Brostom-Gould. There are however certain scenarios where this may be unsuitable, such as in hyperlaxity, poor native tissue or revision surgeries. In these situations, a reconstruction with some form of augmentation or grafting is necessary. The anterior half of peroneus longus (AHPL) has gained in popularity as an autograft due to its favourable tendon properties, ease of harvesting, and low reported morbidity. This technique has been adopted by the senior author in these situations. Our primary aim was to assess patient reported outcomes and satisfaction following this surgery. Our secondary objectives were to assess return to sports, donor site morbidity and to report any surgical complications. We performed a retrospective single surgeon study on all patients who underwent CLI reconstruction using the anterior half of peroneus longus between 2014 and 2021. Data was collected prospectively. The Karlsson foot and ankle scoring chart as well as a simple satisfaction table were used to assess outcomes. Minimum follow up was 1 year. 44 patients met the inclusion criteria. 23 women, 21 men. The average age was 37.0 (+−13.5). 24 were very satisfied with the surgery, 10 were satisfied, 6 were fair and 4 were dissatisfied. The average Karlsson score improved from 65/90 (34–77) to 85/90 (range 45–90). The average return to sport was 5 months. There was 1 non-surgical complication recorded. There was no repeat surgery for a complication, or recurrent instability and no donor-site morbidity was reported. The results of our study demonstrates that the CLIR using AHPL is a reliable, predictable and safe

Introduction. Early clinical examination combined with MRI following a high ankle sprain allows accurate diagnosis of syndesmosis instability. However, patients often present late, and for chronic injuries clinical assessment is less reliable. Furthermore, in many centres MRI may be not be readily available. The aims of the current study were to define MRI characteristics associated with syndesmosis instability, and to determine whether MRI patterns differed according to time from injury. Methods. Retrospectively, patients with an unstable ligamentous syndesmosis injury requiring fixation were identified from the logbooks of two fellowship trained foot and ankle surgeons over a five-year period. After exclusion criteria (fibula fracture or absence of an MRI report by a consultant radiologist), 164 patients (mean age 30.7) were available. Associations between MRI characteristics and time to MRI were examined using Pearson's chi-square tests or Fisher's exact tests (significance set at p< 0.05). Results. Overall, 100% of scans detected a syndesmosis injury if performed acutely (within 6 weeks of injury), falling to 83% if performed after 12 weeks (p=0.001). In the acute group, 93.5% of patients had evidence of at least one of either PITFL injury (78.7%), posterior malleolus bone oedema (60.2%), or a posterior malleolus fracture (15.7%). In 20% of patients with a posterior malleolus bone bruise or fracture, the PITFL was reported as normal. The incidence of posterior malleolus bone bruising and fracture did not significantly differ according to time. Conclusion. For unstable ligamentous syndesmosis injuries, MRI becomes less sensitive over time. Importantly, posterior malleolus bone oedema or fracture may be the only evidence of a posterior injury. Failure to recognise instability may lead to inappropriate management of the patient, long term pain and arthritis. We therefore advocate early MRI as it becomes more difficult to ‘grade’ the injury if delayed
