RESUMEN
INTRODUCTION: Deep surgical site infection (SSI) may be a complication of open reduction and internal fixation (ORIF) of calcaneal fractures. This study aimed to describe the characteristics of patients with deep SSI following ORIF of calcaneal fractures via extensile lateral approach (ELA). We compared clinical outcomes of these patients, with a minimum follow-up of one year after successful treatment of deep SSI with a matched control group. METHODS: In this retrospective case-control study, demographic data, fracture characteristics, bacterial pathogens, medical treatments and surgical approaches were collected, also the outcome was evaluated by the visual analog scale (VAS) for pain, foot function index (FFI) and AOFAS ankle-hindfoot score. The differences in Böhler and Gissane's angles between infected and contralateral feet were measured. By matching a control group of uninfected cases, clinical outcomes were compared between 2 groups using the Mann-Whitney U test. RESULTS: Among 331 calcaneus fractures in 308 patients (mean age, 38.0 ± 13.1; male/female ratio, 5.5), 21 had deep SSI (6.3 %). There were 16 (76.2 %) males and 5 (23.8 %) females with a mean age of 35.1 ± 11.7 years. Thirteen (61.9 %) patients had unilateral fractures. The most common Sanders Type was found to be type II. The most frequent type of detected microorganisms was Staphylococcus species. Intravenous antibiotic therapy, mostly clindamycin, imipenem and vancomycin, based on the microbiological results, was prescribed with a mean±SD duration of 28.1 ± 16.5 days. The mean number of surgical debridements was 1.8 ± 1.3. Implants needed to be removed in 16 (76.2 %) cases. Antibiotic-impregnated bone cement was applied in three (14.3 %) cases. The clinical outcomes of 15 cases (follow up, 35.5 ± 13.8; range, 12.6-64.5 months) were 4.1 ± 2.0, 16.7 ± 12.3 and 77.5 ± 20.8 for VAS for pain, FFI % and AOFAS ankle-hindfoot score, respectively. Comparing with the control group (VAS for pain, 2.3 ± 2.7; FFI %, 12.2 ± 16.6, and AOFAS, 84.6 ± 18.0), only VAS pain was statistically lower in this group (p-value: 0.012). The differences in Böhler and Gissane's angles between both feet of infected cases were - 14.3 ± 17.9 and - 7.7 ± 22.5 (worse in the infected side), respectively. CONCLUSION: Proper on-time approaches to deep infection following ORIF of calcaneal fractures may lead to acceptable clinical and functional outcomes. Sometimes aggressive approaches with intravenous antibiotic therapy, multiple sessions of surgical debridement, removal of implants and antibiotic impregnated cement are necessary to eradicate deep infection. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Complete isolated calcaneal dislocation, defined as dislocation of talocalcaneal and calcaneocuboid joints with intact talonavicular joint without significant fracture, is an exceedingly rare injury. CASE PRESENTATION: A 49-year-old man, after a motor vehicle collision, presented with a closed isolated anterolateral dislocation of the calcaneus associated with fracture of the sustentaculum tali, cuboid, lateral process of the talus, and avulsion fracture of superior peroneal retinaculum. Urgent successful closed reduction was immediately performed in the emergency room under sedation. Two days later, through sinus tarsi approach extended proximally to posterior of the lateral malleolus and distally to the calcaneocuboid joint, peroneal tendons were reduced in the retromalleolar groove and avulsion fracture of the superior peroneal retinaculum was reduced and fixed by a suture anchor. A chondral lesion (6 × 8 mm) was seen in the posterior facet of the calcaneus for that chondroplasty and microfracture were performed. Also, small bony fragments from the cuboid were excised. The reduced calcaneocuboid joint was fixed by two Kirschner wires. In the second stage, 10 days later, through medial approach to the talocalcaneal joint, multiple free bony fragments were excised. Then sustentaculum tali was reduced and fixed using a lag screw. Postoperatively, a non-weight bearing short leg cast was applied for six weeks. The patient had permission to start partial weight bearing 6 weeks after removal of K-wires. Finally, at the 10th postoperative week, he had full weight-bearing without any aid instrument. He was able to return to his regular activities about 6 months after the injury. At 34 months, the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale was 92 from 100. The foot function index percentile was 7% and the visual analogue score for pain was 1.9. The last radiographs revealed normal configuration of talocalcaneal, calcaneocuboid, and talonavicular joints with a little joint space narrowing in posterior part of the subtalar joint. CONCLUSION: Patients with isolated anterolateral calcaneal dislocations, even with multiple associated fractures, can have acceptable outcomes, if it is urgently diagnosed and properly managed.

BACKGROUND: Inherent characteristics of extensile lateral approach (ELA) for fixation of displaced intraarticular calcaneal fractures together with delayed or probably insufficient physical therapy programs may lead to weakness of the muscle groups crossing the ankle joint. Peroneal tendons might be involved more than others because of possible postoperative adhesions. The aim of this study was to evaluate the isokinetic strength of the muscle groups crossing the ankle joint and also to assess balance and functional ability in this group of patients. METHODS: Based on a pilot study, 23 patients undergone open reduction and internal fixation (ORIF) via ELA and 22 healthy subjects as the control group participated in this observational cross-sectional study. Patients more than 20 years of age with at least 12 months passed their unilateral closed intraarticular calcaneal fracture fixation without any postoperative complications like infection or wound dehiscence were included. Patients with history of concomitant lower extremity injury, spine trauma or surgery, cases underwent removal of calcaneal plates, and cases with neuromuscular or vestibular dysfunction were excluded. The outcome was assessed by isokinetic parameters such as peak torque, peak torque normalized to body weight, mean power and total work modified star excursion balance test, triple hop for distance test, and evertor-to-invertor (E/I) strength ratio. Isokinetic tests were performed at 60 and 120°/s. RESULTS: Greater strength was observed in all muscles in the control group at 60°/s (p < 0.05). Evertors and invertors were weaker in the operated group at 120°/s in comparison to the dorsiflexors and plantarflexors. Modified star excursion (p: 0.003) and triple hop tests (p: 0.001) were lower in the operated group. E/I ratio was not statistically significant between the two groups at 60°/s (p: 0.44) and 120°/s (p: 0.62). CONCLUSIONS: Strength deficit in all muscle groups crossing the ankle joint, and not evertors in isolation, in addition to balance and functional impairments would be seen one year following ORIF of calcaneal fracture via ELA. A long-term rehabilitation program emphasizing different kinds of contraction at low and high speeds and balance training in these patients is highly recommended.

INTRODUCTION: Postoperative pain control and achieving opioid-free anesthesia are major issues for surgically treated patients with calcaneal fractures. We evaluated the potential role of posterior tibial and sural nerve blocks as a part of multimodal pain control techniques in patients underwent open reduction and internal fixation (ORIF) of calcaneal fractures via extensile lateral approach. METHODS: Forty-eight patients randomly allocated to receive either posterior tibial and sural nerve blocks with bupivacaine (peripheral nerve block (PNB) group) or normal saline, after induction of general anesthesia. Patients were assessed for pain intensity, Interval from entrance to the recovery room to the first request for analgesic, recovery room and ward morphine consumption, global satisfaction and morphine side effects. RESULTS: PNB group had less pain score compared to sham block (SB) group at each time point measurement during recovery room stay. There was also significant difference between the 2 groups regarding the pain scores after 2, 4 and 6 h of the operation in the ward. Time to the first request for analgesic was significantly prolonged in the PNB group (P < 0.001). The recovery room and ward morphine consumption was significantly lower in the PNB group (P < 0.001). Global satisfaction in PNB group was significantly more than that of SB group. No complication related to the nerve block was detected at the first postoperative visit in the outpatient clinic. CONCLUSION: Peripheral nerve block could result in less postoperative pain especially in the early hours after ORIF of calcaneal fractures and reduce opioid administration within the first 24 h following the surgery.

INTRODUCTION: Calcaneal fractures may have lifelong debilitating sequences, if not treated properly. Identifying different types of calcaneal fractures based on the computed tomography (CT) scans can increase our conception about these fractures. METHODS: In a cross-sectional study, the available CT images of all consecutive patients with the diagnosis of calcaneal fracture, from January 2015 to December 2018, were reviewed to determine different patterns and types of these fractures. RESULTS: CT images of 886 patients (mean age, 41.29 ± 14.9; range, 3-89 years; male/female, 4.86; pediatric: 3.7%) with 957 calcaneal fractures were evaluated. The peak incidence of calcaneal fractures was seen in patients between 30 to 39 years of age (29%). The rate of open fractures and bilateral involvements were 2.4% and 8.0%, respectively. Among 680 (71.0%) intra-articular calcaneal fractures, subtalar calcaneal fractures were the most common type (94.3%). The majority of intra-articular subtalar calcaneal fractures were displaced (95.0%) with calcaneocuboid joint (CCJ) involvement (59.9%). Fracture lines were extended to the CCJ in about 86.9% of Sanders type IV, 66.3% of type III, and 60.2% of type II. Among 261 extra-articular fractures (27.3%), calcaneal body fracture (55.6%) was the most frequent type, followed by medial tubercle fracture (24.1%), calcaneal tuberosity fracture (10.4%), Degan type I anterior process fractures (5.4%), Degan type II anterior process fracture (3.4%), and isolated lateral tubercle fracture (1.1%). Most of bilateral calcaneal fractures were intra-articular subtalar fractures with involvement of CCJ. Although majority of intra-articular calcaneal fractures were displaced; less than half of the extra-articular fractures were displaced. CONCLUSION: Displaced intra-articular subtalar calcaneal fractures with CCJ involvement are the most frequent type of unilateral and bilateral calcaneal fractures. It appears that there is a correlation between Sanders type and the probability of CCJ involvement. Unlike intra-articular subtalar calcaneal fractures, the CCJ in the majority of extra-articular calcaneal body fractures was intact. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: Categorizing different injury patterns of the talus, describing demographic data, mechanisms of injury and associated fractures are important issues in orthopedic trauma surgeries. Injuries of the talus require careful attention with appropriate treatment approaches in order to reduce possible complications. METHODS: In a cross-sectional study, the demographic characteristics, mechanism of injury, fracture type, and associated fractures were compiled from all patients' files and operation notes with diagnosis of talar injuries from January 2014 to December 2019. RESULTS: Among 367 patients, 317 (86.4%) males and 50 (13.6%) females with mean age of 31.8 ± 11.6 years were identified. There were three (0.8%) patients with bilateral talar fractures. The most common mechanism of injury was motor vehicle accident (MVA) (46.1%), followed by falls (43.3%), direct trauma (6.2%) and sport injuries (4.4%). About half of the patients injured in MVAs were motorcyclists. Isolated talar body fractures (21.9%) were more common than isolated talar neck (19.2%) or combined body & neck fractures (14.6%). Isolated lateral process fracture is the most frequent fractured process of the talus (14.3%). Hawkin type IIA (39.2%) was the most common type of talar neck, followed by Hawkin type III (22.3%), type I (21.5%), type IIB (14.6%) and type IV (2.3%). Medial malleolus, fibula and calcaneus were the most common associated fractures, respectively. CONCLUSIONS: The population that is most affected by talar injury are active young men who are involved in motor vehicle accidents, especially motorcycle crashes, with fracture of body and/or neck of talus being the most common type.

PURPOSE: The main aim of this study was to investigate the correlation between radiographic findings and clinical outcomes following the first metatarsophalangeal (MTP) joint arthrodesis. METHODS: In a comparative retrospective study, on 46 patients (48 ft), the correlation between post-operative radiographic findings including hallux valgus angle (HVA) and first MTP dorsiflexion angle (MTPDA) and clinical outcomes including VAS pain, modified AOFAS hallux score, and FFI questionnaire were evaluated. Moreover, clinical outcomes were compared between cases with pre-operative diagnosis of first MTP inflammatory arthritis, hallux valgus, hallux varus, and grade 3 and 4 of hallux rigidus. The effect of first MTP arthrodesis on Meary's angle and intermetatarsal angle (IMA) were found out. RESULTS: The mean age of the patients was 56.3 ± 9.1 (range, 29-69) years, including 42 (91.3%) females and 4 (8.7%) males. We had fusion rate of 97.9%, one asymptomatic nonunion case (2.1%). Totally, mean scores of modified AOFAS hallux score, FFI percentage, and VAS pain were 88.9 ± 12.6, 9.4 ± 16.5, and 1.23 ± 2.24, respectively. Hallux varus was associated with the most favourable outcomes; whereas, patients with first MTP arthritis got the worst outcome. Regression analysis test between clinical outcomes and HVA > 15° and first MTPDA >15° showed correlation coefficient of almost zero. No statistically significant differences were found between the clinical outcomes of grade 3 and 4 of hallux rigidus (p value of modified AOFAS hallux score, FFI percentage, and VAS pain: 0.879, 0.906, and 0.298, respectively). Mean of HVA and IMA reduction in 15 hallux valgus underwent first MTP fusion were 34.4° and 8.4°, respectively. Meary's angle increased about 4° with statistically significant difference (p value 0.001). CONCLUSION: Patients with first MTP fusion > 15° in coronal and transverse plans could have acceptable clinical outcomes. The clinical outcome of first MTP arthrodesis for grade 3 hallux rigidus is comparable with grade 4. First MTP fusion would have positive effect on IMA and Meary's angle.

During extensile lateral approach to the calcaneus, in order to see all fractured fragments and subtalar joint, all soft tissues including insertion site of superior peroneal retinaculum (SPR) on the calcaneus should be released. The aim of this study was to evaluate the probability of peroneal tendon dislocation by releasing all soft tissues attached to the calcaneus. In 10 fresh cadavers, after standard extensile lateral approach to the calcaneus in right side, all soft tissues attached to the lateral wall of the calcaneus were excised. In the left side of each cadaver, all soft tissues inserted to the superior border of calcaneal tuberosity in addition to the lateral wall of the calcaneus were cut out. Probable anterior dislocation of peroneal tendons in the retromalleolar groove was assessed by placing a clamp into the peroneal tendon sheath from distal to proximal and advancing it to the retromalleolar groove. Also by careful dissection, any instability of peroneal tendons was visualized. Not any anterior dislocation of peroneal tendons to the lateral malleolus tip was seen in any stage of the procedure. Insertions of the SPR to the fascia of the deep posterior compartment of the leg and the Achilles tendon sheath are the main soft tissue stabilizer of the peroneal tendons in the retromalleolar groove. So resection of the insertion site of the SPR to the calcaneus might not result in the peroneal tendon instabilities.

PURPOSE: The hypertrophied peroneal tubercle may result in lateral ankle pain with peroneal tendon tenosynovitis and rupture. The aim of this study was to evaluate different configurations and dimensions of the normal peroneal tubercle using two-dimensional CT scan. METHODS: Totally, 100 normal CT scans of cases older than 18 years of age were assessed to determine the shape of the peroneal tubercle. Moreover, height, length and width of different configurations of the normal peroneal tubercle were measured in axial and coronal sections of the ankle CT scans. RESULTS: Four different configurations based on the axial cut of the calcaneus were found; single-convex (59%), double-convex (24%), plateau (9%), and convex-concave (8%) without statistically significant difference between genders (p-value: 0.526). Totally, mean of height, length and width were 4.42 ± 1.38 mm, 28.88 ± 6.58 mm and 17.17 ± 3.85 mm, respectively. Although mean of the height in the single-convex and the double-convex types were 4.5 ± 1.4 mm and 5.0 ± 1.4 mm, respectively, the highest peroneal tubercle in the single-convex and the double-convex group were 10.2 mm and 8.5 mm, respectively. CONCLUSIONS: In cases with lateral ankle pain and suspicious to hypertrophied peroneal tubercle, two-dimensional CT scan can be an available practical modality to identify the pathological type of the peroneal tubercle based on the presented classification and normal values. As previously reported in the literature, considering cut-off point of 5 mm could result in overdiagnosis of the hypertrophied peroneal tubercle, especially in single-convex type; however, clinical correlation is always paramount. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: The Score Committee of the European Foot and Ankle Society (EFAS) developed, validated, and published the EFAS Score in nine European languages (English, German, French, Italian, Polish, Dutch, Swedish, Finnish, Turkish). From other languages under validation, the Persian version finished data acquisition and underwent further validation. METHODS: The Persian version of the EFAS Score was developed and validated in three stages: 1) item (question) identification (completed during initial validation study), 2) item reduction and scale exploration (completed during initial validation study), 3) confirmatory analyses and responsiveness of Persian version (completed during initial validation study in nine other languages). The data were collected pre-operatively and post-operatively at a minimum follow-up of 3 months and mean follow-up of 6 months. Item reduction, scale exploration, confirmatory analyses and responsiveness were executed using classical test theory and item response theory. RESULTS: The internal consistency was confirmed in the Persian version (Cronbach's Alpha 0.82). The Standard Error of Measurement (SEM) was 0.38 and is similar to other language versions. Between baseline and follow-up, 97% of patients showed an improvement on their EFAS score, with excellent responsiveness (effect size 1.93). CONCLUSIONS: The Persian EFAS Score version was successfully validated in patients with a wide variety of foot and ankle pathologies. All score versions are freely available at www.efas.co.

We evaluated the reliability and validity of the Persian translation of the American Orthopedic Foot and Ankle Society hallux metatarsophalangeal-interphalangeal joint scale (AOFAS Hallux MTP-IP). The translated AOFAS Hallux MTP-IP scale form was completed for 101 patients with hallux deformities; the subjective questions were answered by the patients, whereas the orthopedic foot and ankle surgeon and his assistant answered the objective questions. The validated Persian version of the 36-Item Short Form Survey Instrument (SF-36) was used for validity assessment. Eighty-five females and 16 males with a mean age of 49 years were enrolled. Hallux valgus and hallux rigidus was the diagnosis in 73 and 28 patients, respectively. Intrarater reliability had a high level of correlation (rho >0.6) for all subscales and total score. Although the correlation between the total score of the AOFAS Hallux MTP-IP scale and role: physical subscale of SF-36 was the highest (rhoâ¯=â¯0.47), the total score of AOFAS Hallux MTP-IP scale and the other 7 domains of SF-36 had a correlation ranging between -0.17 and 0.43. Moreover, the correlation between total score of AOFAS-Hallux MTP-IP and SF-36 physical component summary scale was 0.50, which was higher than the correlation between total score of AOFAS and SF-36 mental component summary scale (rhoâ¯=â¯0.35). Convergent validity was approved for MTP joint motion (0.59), IP joint motion (0.51), and callus (0.56) items of AOFAS-Hallux MTP-IP. Spearman's rank correlation coefficient between all items of the functional subscale of AOFAS Hallux MTP-IP scale with its own subscales was higher than the coefficient between these items and other subscales, including pain and alignment (discriminate validity). Floor and ceiling effects were calculated as 2% and 1%, respectively. Our findings indicate that the translated Persian version of the AOFAS Hallux MTP-IP scale is a reliable instrument, but its validity is not satisfactory.

The combination of tendon and ligament ruptures with fracture of the talus is very rare. We demonstrate our experience in the acceptable management of a 34-year-old male referred with a closed comminuted fracture of the talar body after falling 7 meters. During the surgery, complete rupture of the peroneus brevis tendon, partial rupture of the peroneus longus tendon, and an avulsed superficial deltoid ligament from medial malleolus were found. Twelve months after open reduction and internal fixation of the talar body fracture and repair of the peroneal tendons and superficial deltoid ligament, the patient was satisfied, without any talar dome collapse, sclerosis, or arthritic changes. It is recommended to take care of possible tendon or ligament ruptures during fixation of talar fractures in cases of high-energy trauma.

BACKGROUND: Sanders classification, based on the number of displaced fractured fragments of posterior facet, can predict the prognosis of calcaneal intraarticular fractures. The aim of the study was assessing not only intraobserver reproducibility and interobserver reliability of Sanders classification but also the agreement between preoperative reported types based on computed tomography (CT) scan and direct observation during the surgery. METHODS: In this cross-sectional study, preoperative CT scans of 100 patients with intra-articular calcaneal fracture operated by a single surgeon were studied by two orthopedic and trauma surgeons (A & B), twice with an interval of three weeks. Their result were compared with each other and with the number of displaced fractured fragments recorded in the operation notes. Quadratic weighted kappa test was used to check the agreement between two observers and between the observers and the surgeon. RESULTS: Intraobserver reproducibility for Sanders classification of intraarticular calcaneal fractures was found to be good to excellent (A1-A2: 0.91 and B1-B2: 0.75). There was a moderate agreement between the two observers (A1-B1: 0.56, A1-B2:0.58, A2-B1:0.48, and A2-B2:0.51). The agreement between reported types of Sanders classification and the number of displaced fractured fragments seen during the surgery was fair (A1-surgeon: 0.27, A2-surgeon: 0.29, B1-surgeon: 0.38, and B2-surgeon: 0.50). CONCLUSIONS: Agreement between Sanders classification and what is real during surgery is fair. Hence, Sanders classification as determined in the widest cut of coronal CT scan extended posteriorly should be cautiously interpreted for surgery.

Tibialis anterior tendon (TAT) rupture is a rare injury that commonly diagnosed late due to mild clinical signs and symptoms. Management of TAT rupture is a topic without a clear consensus in the literature. This current concept review tries to shed some light on the data and treatment. Our extensive literature review identified 81 case reports and case series from 1905 to 2018. Several reported management techniques with their advantages and disadvantages were analyzed and our treatment recommendations are given based on current available evidences. LEVELS OF EVIDENCE: IV.

BACKGROUND: Intralesional curettage and adjuvant versus wide en bloc excision (WEE) as the best treatment method of giant cell tumor (GCT) of distal radius with limited soft tissue extension is a controversial topic. METHODS: Prospectively, 13 patients who had GCT of distal radius with perforation of either volar or dorsal cortex of the bone and soft tissue extension which was confined to one plane were enrolled in the study. Six patients treated with ICC and seven cases cured by WEE technique and proximal fibular arthroplasty. The results were evaluated based on recurrence, range of motion of the wrist joint, rotation of the forearm, grip and pinch power. RESULTS: The mean age of the patients treated with ICC and WEE techniques were 32.7 (range: 23-43) and 34.5 (range: 28-44), respectively. Mean follow-up period was 72 months (range: 28-148). Local recurrence was seen in 4 of 6 patients (66.7%) underwent ICC technique but in none of the 7 subjects treated with WEE technique (P value = 0.021). The overall range of flexion/extension and supination/pronation in the WEE group were 83% and 92% of the ICC group, respectively. Both of pinch and grip power were 14% less in the WEE group compared to the ICC group. CONCLUSIONS: In GCT lesion of distal radius even with limited soft tissue extension, WEE and proximal fibular arthroplasty may be a more reasonable suggestion when the patient seeks a one-shot surgery.

BACKGROUND: The use of valid and reliable outcome rating scales is essential for evaluating the result of different treatments and interventions. The purposes of this study were to translate and culturally adapt the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale (AOFAS-AHFS) into Persian languages and evaluate its psychometric properties. METHODS: Forward-backward translation and cultural adaptation method were used to develop Persian version of AOFAS-AHFS. From March to July 2016, one hundred consecutive patients with ankle and hindfoot injuries were included. Internal consistency and reproducibility were evaluated using Cronbach's alpha, Spearman's rank correlation coefficient and Intraclass correlation coefficient (ICC) respectively. Construct validity reported which compare the outcome rating scale measurements with Short Form-36 (SF-36), also convergent and discriminant validity evaluated using Spearman's rank correlation coefficient. RESULTS: Mean age (SD) of the patients was 41.95±13.45years. Cronbach's α coefficient, Spearman's rho and ICC values were 0.71, 0.89 and 0.90 respectively. Total score of AOFAS-AHFS and SF-36 domains has a correlation ranged between 0.17-0.55. Spearman's rank correlation coefficient of 0.4 was exceeded by all items with the exception of stability. The Spearman's rank correlation between each item in functional subscales with its own subscales was higher than the correlation between these items and other subscales. CONCLUSIONS: Persian version of AOFAS-AHFS provides additional reliable and valid instrument which can be used to assess broad range of patients with foot and ankle disorders that speaking in Persian. However, it seems that the original version of AOFAS-AHFS needs some revisions.

OBJECTIVE: Diagnosis of acetabular retroversion based on crossover sign in the anteroposterior radiograph of the hip joint is well described. Accuracy of the crossover sign to identify global retroversion of the acetabulum in comparison to version of the acetabulum in reconstructed three-dimensional computed tomography (3D CT) scan of the hip was the aim of this study. MATERIALS AND METHODS: X-rays of 500 hips were assessed regarding presence of crossover sign and its location in the upper, middle, or lower third of the acetabulum. Mean of anteversion and true retroversion (defined as less than one standard deviation below the mean of acetabular anteversion) of the acetabulum using reconstructed 3D CT scan by mathematical software was determined among 500 hips. The positive and negative crossover signs were compared to the retroversion obtained by CT scan. RESULTS: The average of acetabular anteversion was 12.5 ± 4.2 degrees. True global retroversion in 3D CT scans was defined as a version below 8.3 degrees. Although positive crossover sign was seen in 193 out of 500 (38 %), only 69 out of 500 (13.8 %) of hips had version below 8.3 (true retroversion) and 124 subjects had an acetabular version above 8.3. The sensitivity and specificity of crossover signs were about 82 and 70 %, respectively. CONCLUSIONS: The crossover sign could pick up hips with less than normal anteversion with acceptable sensitivity but it has no enough specificity for being used as the sole indication for treatment.

Irreducible ankle fracture-dislocations are very rare entities. The present case report demonstrates an unusual finding of tibialis posterior and flexor digitorum longus tendons interposed in the tibiofibular joint impairing successful closed reduction of ankle fracture-dislocation. A 45-year-old patient presented with a bimalleolar pronation-external rotation ankle fracture-dislocation after a motorcycle accident. Attempts to perform closed reduction before surgery were unsuccessful. Subsequent urgent open reduction and internal fixation surgical management revealed interposition of the tibialis posterior and flexor digitorum longus tendons in the tibiofibular joint. In irreducible fracture-dislocation of the ankle with severe lateral displacement of the talus, one should be aware of the possibility of soft tissue interposition of the tibialis posterior and flexor digitorum longus tendons in the tibiofibular joint.

Traumatic lateral dislocations of the first metatarsophalangeal (MTP) joint are very rare. A 44-year-old male was referred after a motorcycle to car accident because of an exposed head of the left first metatarsal through a laceration on the medial aspect of the first MTP joint. Radiographs showed a lateral dislocation of the first MTP joint, with concomitant fractures of the neck of the second metatarsal and the base of the third and fourth metatarsal bones. The dislocation was reduced in the emergency department with the patient under conscious sedation after thorough irrigation. At the 1-year postoperative visit, the patient had full painless range of motion of the first and second MTP joints without any complaints. Lateral dislocation of the first MTP joint is an injury usually associated with fracture of the adjacent metatarsals and/or ligamentous injuries. It is easily reducible, with acceptable midterm outcomes.
