PURPOSE OF THE STUDY Extended lateral approach to calcaneus fractures is associated with a high risk of infection. Such risk can be reduced by using mini-invasive approaches. The sinus tarsi approach provides a good overview of the posterior joint facet of the calcaneus and can also be done as a mini-invasive procedure. The authors present their fi rst experience with osteosynthesis of joint depression calcaneal fractures using the anterolateral locking plate inserted through the sinus tarsi approach. MATERIAL AND METHODS During the period from 1 February 2020 to 31 January 2022, 18 patients were treated by the anterolateral locking plate in the authors' department (3 women, 15 men). Eleven fractures were classifi ed according to Sanders as IInd grade, fi ve as IIIrd grade and two fractures were classifi ed as tongue-type (as described by Essex-Lopresti). The fractures were treated by open reduction through the sinus tarsi approach and osteosynthesis by the anterolateral locking plate combined with headless screws. The following factors were examined: time from injury, duration of surgery, quality of reduction (post-op control with multiplanar CT scans), wound and technical complications, loss of reduction after treatment, substance abuse and comorbidities. The follow-up was 12-36 months (median 17). At one year after surgery, the functional outcomes were evaluated using the AOFAS Hindfoot score. RESULTS The most common negative predispositions for successful healing were smoking (9 cases), alcohol abuse, drug abuse, mild mental retardation, personality disorder, insulin-dependent diabetes and epilepsy (1 case each), hypothyreodism and bronchial asthma (2 cases each). The time from injury to surgery and duration of surgery surgery were measured. The quality of reduction was excellent in 12 patients (dislocation less than 1 mm), good in 6 patients (dislocation less than 2 mm), dislocation more than 2 mm was not present in the group. In one case, a revision surgery was performed because of screw malposition into the subtalar joint, delayed wound healing was observed in two cases. There was no case of deep surgical site infection or loss of reduction. The mean AOFAS score after one year was 85 points. The most common complaints were scar pain or discomfort. DISCUSSION The current studies on osteosynthesis of calcaneal fractures favor the sinus tarsi approach for its lower risk of wound-related complications compared to the extended lateral approach. The sinus tarsi approach requires the use of different osteosynthetic material than the conventional calcaneal plate. If a conventional locking plate is to be used, the surgical approach has to be modifi ed. In 2021, Wang et al. published an intermediate step leading to the reduction of early complications and the use of conventional locking calcaneal plate inserted through the sinus tarsi approach, with an additional incision. The sinus tarsi approach is used also when intramedullary nailing is performed, which is preferred by biomechanical studies evaluating the rigidity of osteosynthesis. However, when comparing nails and locking plates, the differences are insignifi cant. The use of anterolateral locking plates was presented by Xie et al., with results similar to those of our own group of patients. CONCLUSIONS The results of the followed-up group of patients confi rm low complication rate of the sinus tarsi approach as reported by current literature. At the same time, it provides good options for reduction even in complicated fractures. For successful osteosynthesis, the anterolateral locking plate with headless screws may be used. The incidence of post-operative complications is low even in high-risk patients. Adhesions of peroneal tendons can be treated with material removal and tissue release. They could be prevented by good physiotherapy. Key words: calcaneus, osteosynthesis, anterolateral plate, peroneal tendons, sinus tarsi approach.

INTRODUCTION: Complex ankle fractures frequently include the posterior malleolus (PM). Despite advances in diagnostic and treatment strategies, PM fracture involvement still predisposes to worse outcomes. While not incorporated into the most common PM fracture classifications, the presence of an intercalary fragment (ICF) complicates treatment. This study aims to describe the incidence, morphology, and location of ICFs in PM fractures. MATERIALS AND METHODS: A total of 135 patients with a mean age of 54.4 (SD ± 18.9) years and PM fractures were analyzed for the presence of an ICF. Patients with an ICF were compared to those without in terms of age, gender, and treatment received. Characteristics of the ICFs in terms of location and size were assessed. Furthermore, the presence of an ICF in relation to the PM fracture classification according to Haraguchi et al., Bartoníček/Rammelt et al., and Mason et al. was investigated. RESULTS: ICFs presented in 55 (41%) of the 135 patients. Patients with an ICF were younger, and the PM was more often operatively treated when compared to patients without an ICF. A posterolateral approach was used significantly more often in patients with an ICF. Almost all ICFs were found in the posterolateral (58%) and posterocentral (35%) regions. The majority of fragments were found in Bartoníček/Rammelt type 2 fractures, the most common fracture type. Bartoníček/Rammelt type 3 fractures had the highest relative frequency of ICFs. CONCLUSION: ICFs are frequently found in PM fractures; however, they are not incorporated into any of the common classifications. They are generally found in younger patients and associated with more complex PM fractures. As they can complicate reduction of the main fragment and may require direct exposure to restore joint congruency, ICFs should be considered in PM fracture classifications. Due to their location, the majority of ICFs are able to be accessed using a posterolateral approach.

There are relatively few running studies that have attempted to prospectively identify biomechanical risk factors associated with Achilles tendon (AT) injuries. Therefore, the aim was to prospectively determine potential running biomechanical risk factors associated with the development of AT injuries in recreational, healthy runners. At study entry, 108 participants completed a set of questionnaires. They underwent an analysis of their running biomechanics at self-selected running speed. The incidence of AT running-related injuries (RRI) was assessed after 1-year using a weekly questionnaire standardized for RRI. Potential biomechanical risk factors for the development of AT RRI injury were identified using multivariable logistic regression. Of the 103 participants, 25% of the sample (15 males and 11 females) reported an AT RRI on the right lower limb during the 1-year evaluation period. A more flexed knee at initial contact (odds ratio = 1.146, P = .034) and at the midstance phase (odds ratio = 1.143, P = .037) were significant predictors for developing AT RRI. The results suggested that a 1-degree increase in knee flexion at initial contact and midstance was associated with a 15% increase in the risk of an AT RRI, thus causing a limitation of training or a stoppage of running in runners.

Maisonneuveova zlomenina (MZ) je definována jako luxační zlomenina hlezna, kde došlo vždy ke zlomenině proximální čtvrtiny fibuly a roztržení lig. tibiofibulare anterius a lig. tibiofibulare interosseum. Další poranění jsou variabilní. Recentní CT studie ukázaly, že MZ je mnohem komplexnější poranění, než se předpokládalo. Proto je třeba zásadním způsobem změnit pohled na tuto problematiku. MZ je spojena přibližně v 80 % případů se zlomeninou malleolus posterior a dále s malpozicí distální fibuly v incisura fibularis tibiae (IFT). Přesné zhodnocení těchto poranění vyžaduje úrazové CT, které by mělo být u MZ v dnešní době standardem. Hlavním cílem ošetření je anatomická repozice distální fibuly do IFT. To vyžaduje v případě odlomení většího fragmentu malleolus posterior provést nejdříve jeho repozici a fixaci z posterolaterálního přístupu. Tím dojde k obnovení integrity IFT. Zavřená repozice distální fibuly je spojena s malpozicí až v 50 % případů. Proto se dává přednost otevřené repozici z krátkého anterolaterálního přístupu. Přesnost repozice je nutné vždy ověřit pooperačním CT.

Maisonneuve fracture (MF) is defined as an ankle fracture-dislocation associated always with a fracture of the proximal quarter of the fibula and rupture of the anterior and interosseous tibiofibular ligaments. Other injuries are variable. Recent CT studies have demonstrated that MF is a far more complex injury than initially supposed. Therefore it is necessary to change substantially the current concepts related to this issue. MF is combined in about 80% of cases with a fracture of the posterior malleolus and also with malposition of the distal fibula in the fibular notch. An exact assessment of these injuries requires post-injury CT examination which should be used as a standard in MFs. The main goal of treatment is anatomical reduction of the distal fibula into the fibular notch. In case of avulsion of a larger fragment of the posterior malleolus, it is necessary to perform as the first step its reduction and fixation from the posterolateral approach and thus restore integrity of the notch. Closed reduction of the distal fibula is associated with malposition in up to 50% of cases and therefore open reduction from a short anterolateral approach is preferred. Accuracy of reduction should be always checked by postoperative CT scan.

Bosworthova zlomenina (BZ) je vzácné, ale závažné poranění hlezna, charakterizované dislokací fragmentu zlomené fibuly (většinou typ Weber B) z incisura fibularis tibiae na zadní plochu distální tibie. V 70 % případů je doprovázeno zlomeninou malleolus posterior. Toto poranění není příliš známé, v literatuře bylo dosud popsáno 175 případů. BZ vyžaduje CT vyšetření včetně 3D rekonstrukcí. Zavřená repozice je téměř vždy neúspěšná a opakované pokusy zvyšují riziko kompartment syndromu. Proto je vždy indikována operační léčba. Výsledek operace je třeba zkontrolovat na pooperačním CT.

Bosworth fracture (BF) is a rare, but a severe injury to the ankle, characterized by displacement of a fragment of the fractured fibula (mostly of Weber B type) from the tibiofibular incisure to the posterior surface of the distal tibia. In 70% of cases, it is associated with a fracture of the posterior malleolus. This injury is not quite well known, with only 175 cases described in the literature to date. BF requires CT examination, including 3D reconstructions. Closed reduction almost always fails as there is an increased risk of compartment syndrome, mainly after repeated attempts at closed reduction. Therefore, operative treatment is indicated as a standard. The outcome of the operation should be always checked by postoperative CT examination.

PURPOSE: During study of anatomy of a fractured posterior malleolus of the ankle on CT scans, the authors noticed a prominent crest on the lateral malleolus, which they termed the lateral malleolar crest (LMC). As, in their view, LMC is a clinically important structure which was only briefly mentioned by a few authors without an official term, they focused on the anatomy of this structure. MATERIALS AND METHODS: A total of 352 dry fibulae were analyzed and the following parameters recorded: (F) length of the fibula, (LMC) total length of LMC, (A) length of the part of the examined crest from the superior border of the articular facet of the lateral malleolus (AFLM) to its most proximal intersection with the midline of the fibula, (B) height of the medial triangular rough surface, and (A/F) A/F ratio. RESULTS: The crest was observed in all specimens. (F) was 346.5 ± 26 mm (95% confidence interval [CI] 344-349), (LMC) was 85.4 ± 11.6 mm (95% CI 84.2-86.6), (A/F) was 25% ± 3% (95% CI 24.7-25.3) in the whole group. (A) was 25.9 ± 6.5 mm (95% CI 24.8-26.8) in the whole group, (B) was 34.9 ± 4.7 mm (95% CI 34.3-35.5) in the whole group, 36 ± 6.1 mm (95% CI 35.1-36.9). CONCLUSION: LMC is an important structure on the lateral malleolus. The knowledge of its anatomy is essential for placement of syndesmotic screws or/and the fibular plate.

PURPOSE OF THE STUDY Minimal and limited access techniques are gaining increasing interest for the treatment of displaced intra-articular calcaneal fractures. The ideal treatment method is however still debated and largely based on individual case factors and surgeon experience. Aim of this study was thus to compare the treatment characteristics and radiographic correction potential of a locking nail system with a sinus tarsi approach to plate fixation via an extended lateral approach. MATERIAL AND METHODS We retrospectively reviewed 39 cases of patients with calcaneal fractures that received primary fracture treatment for displaced intra-articular calcaneal fractures between July 2017 and March 2020. Patient characteristics, time to surgery, time to discharge, OR time and the correction achieved were analyzed and comparative statistics performed. RESULTS In total 19 patients treated with the locking nail and 20 patients treated with plate fixation were analyzed. Patient age and fracture severity according to the Sanders classification were comparable between the groups. Overall surgical time, as well as the achieved reduction was equal between both groups. Time to surgery, as well as time from surgery to discharge was significantly shorter in the locking nail group. 2 additional soft tissue procedures were necessary in the extended lateral approach group. DISCUSSION AND CONCLUSIONS The results with the locking calcaneus nail and sinus tarsi approach suggest, that similar treatment results can be achieved as with plate osteosynthesis and an extended lateral approach. Soft tissue management, as well as pre- and postoperative timing and discharge management can be improved with the nail. Further controlled trials comparing the longterm outcome between the treatment options are needed. Key words: calcaneus fracture, sinus tarsi approach, calcaneal nail, C-Nail.

PURPOSE: The aim of this study was to describe pathoanatomy and to raise awareness of a fracture of the lateral malleolus combined with a high subcapital fracture of the fibula caused by a dislocation mechanism. METHODS: The study comprised 11 patients, 5 men and 6 women, with the mean age of 57 years (range, 21-87), with a "Double Maisonneuve fracture". Individual lesions of ankle structures were described on the basis of radiographs, CT, and intraoperative findings. RESULTS: The distal fibular fracture was classified as Weber type B in 1 case and Weber type C in 10 cases. The proximal fibular fracture was described as a subcapital oblique spiral fracture with metadiaphyseal involvement in nine cases and a high short oblique fracture with fibular head involvement in two cases. Injury to the deltoid ligament was revealed in six cases; a bicollicular fracture of the medial malleolus was found in five patients. Posterior malleolar fractures were classified as type 1 in eight cases and type 2 in three cases. Avulsion of the Chaput tubercle was detected in four cases. Injury to the interosseous tibiofibular ligament was assessed in nine patients. CONCLUSION: Double Maisonneuve fracture is a rare but probably underreported injury that must be taken into consideration during examination, as it may be easily overlooked. The essential part of diagnosis is a careful clinical examination and radiological assessment of the lower leg with additional CT examination of the ankle.
