RESUMO
Treatment of calcaneal fractures in patients with diabetes mellitus (DM) is challenging. The purpose of this study was to compare post-operative outcomes after open reduction and internal fixation (ORIF) for calcaneus fracture in patients with complicated DM, uncomplicated DM, and patients without DM. A commercially available de-identified database was queried for all calcaneus fracture diagnoses undergoing ORIF from 2010 to 2021. The patients were separated into three groups for analysis: patients without DM (10,951, 82.6%), uncomplicated DM (1,500, 11.3%) and complicated DM (802, 6.1%). At 1 year, post-operative adverse events were assessed among the three groups. The odds of adverse event(s) for each group were compared between the three groups with and without characteristic matching. In the unmatched cohorts, patients with complicated DM, when compared with patients without DM and patients with uncomplicated DM, had significantly higher rates of all adverse events with exception of DVT. Rates of CNA were significantly higher in patients with complicated DM compared with no DM (OR 107.7 (CI 24.83-467.6) p < 0.0001) and uncomplicated DM (OR 44.26 (CI 3.86-507.93) p = 0.0002). After matching, non-union, AKI, sepsis, surgical site infection, and wound disruption were higher in patients with complicated DM compared with patients without DM. There were no significant differences in the three groups with regard to reoperation, DVT, MI, pneumonia, or below the knee amputation. Patients with DM who underwent ORIF for calcaneus fracture experienced higher rates of post-operative adverse events compared with those patients without DM.

OBJECTIVE: With the development of surgical technology, the level of digital medicine is constantly improving. The birth of new technologies has a certain impact on traditional methods. At present, robot-assisted technology has been applied to patients with calcaneal fractures, which poses a challenge to traditional surgery. We aimed to assess whether robot-assisted internal fixation confers certain surgical advantages through a literature review. DESIGN: The databases PubMed, EMBASE, the Cochrane Library, the China National Knowledge Infrastructure (CNKI), and the Wanfang Data Knowledge Service Platform were systematically searched for both randomized and nonrandomized studies involving patients with calcaneal fractures. MAIN RESULTS: Five studies were identified that compared clinical indexes. For the clinical indexes, robot-assisted surgery is generally feasible because of intraoperative fluoroscopy, complications, the Gissane angle, the calcaneal width, and the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score 3 and 6 months after the operation (P < 0.05). However, on the operation time, Böhler's angle at 3 and 6 months, Gissane angle and calcaneal width at 6 months after the operation did not show good efficacy compared with those of the traditional group (P > 0.05). CONCLUSIONS: Based on the current evidence, the advantages of robot-assisted fixation over traditional fixation are clear. The long-term clinical effects of the two methods are also good, and the short-term effect of robot assistance is better. However, the quality of some studies is low, and more high-quality randomized controlled trials (RCTs) are needed for further verification.

BACKGROUND: This prospective study was undertaken to report outcomes following reconstructive surgery for patients with painful pediatric idiopathic flexible flatfoot. METHODS: Twenty-five patients with pediatric idiopathic flexible flatfoot were evaluated pre- and post flatfoot reconstruction with lateral column lengthening (LCL). All patients had lengthening of the Achilles or gastrocnemius, while 13 patients had medial side soft tissue (MSST) procedures, 7 underwent medial cuneiform plantarflexion osteotomy (MCPO), and 5 had medializing calcaneal osteotomy. Measures of static foot alignment-both radiographic parameters and clinical arch height indices-were compared, as were measures of dynamic foot alignment and loading, including arch height flexibility and pedobarography. Preoperative and postoperative patient-reported outcome (PRO) scores were compared between those treated with or without MSST procedures. RESULTS: The median subject age was 13.8 years (range: 10.3 to 16.5) at the time of surgery. All radiographic parameters improved with surgery ( P <0.001). The mean sitting arch height index showed a modest increase after surgery ( P =0.023). Arch height flexibility was similar after surgery. The mean center-of-pressure excursion index increased from 14.1% to 24.0% ( P <0.001), and the mean first metatarsal head (MH) peak pressure dropped ( P <0.001), while the mean fifth MH peak pressure increased ( P =0.018). The ratio of peak pressure in the fifth MH to peak pressure in the second MH increased ( P =0.010). The ratio of peak pressure in the first MH to peak pressure in the second MH decreased when an MCPO was not used ( P <0.002), but it remained stable when an MCPO was included. Mean scores in all PRO domains improved ( P <0.001). Patients treated without MSST procedures showed no difference in PROMIS Pain Interference scores compared to those without MSST procedures. CONCLUSIONS: Flatfoot reconstruction surgery using an LCL with plantarflexor lengthening results in improved PROs. LCL changes but does not normalize the distribution of MH pressure loading. The addition of an MCPO can prevent a significant reduction in load-sharing by the first MH.

OBJECTIVE: Pes planovalgus is the most common foot deformity seen in patients with cerebral palsy (CP). There are several different treatment modalities to treat this condition. Single or double calcaneal osteotomies, extra-articular arthrodesis, calcaneo-cuboido-cuneiform osteotomy, intraarticular arthrodesis, and arthroereisis are some of these modalities. Currently, there is insufficient information to determine the most effective treatment approach for pes planovalgus in children with CP. The aim of this study is to show the short to mid-term results of the new technique which combines calcaneus lengthening osteotomy, extra-articular subtalar arthrodesis, and soft tissue reconstruction that aims to decrease recurrence and complication rates of pes planovalgus surgery for patients with ambulatory CP. METHODS: Patients with CP who were treated with calcaneal lengthening surgery and extra-articular subtalar arthrodesis between 2018 and 2021 were investigated retrospectively. All patients were ambulatory and Gross Motor Function Classification System I-II-III. Functional levels of the patients were assessed with the American Orthopaedic Foot and Ankle Society, Ankle-Hindfoot Score, and the Foot and Ankle Ability Score (Foot and Ankle Ability Measure) in preoperative and postoperative periods. On anteroposterior x-rays, talus-first metatarsal, talocalcaneal, talonavicular coverage angle and on lateral x-rays talus-first metatarsal, talocalcaneal, calcaneal inclination angle and talar tilt angle were evaluated. RESULTS: The mean follow-up was 46 (range: 36 to 60) months. The mean American Orthopaedic Foot and Ankle Society increased from 41 (20 to 79) to 74 (38 to 93; P < 0.001). The mean Foot and Ankle Ability Measure increased significantly from 35 (7 to 73) to 54 (29 to 96; P <0.001). Clinical results were "satisfactory" for 32 feet, while they were "unsatisfactory" for 2 feet. Significant deformity correction was observed in all radiologic parameters. CONCLUSION: Our technique is found to be efficient for patients with Gross Motor Function Classification System I-II-III CP with pes planovalgus deformity. In short to mid-term follow-up, the technique achieved successful clinical and radiologic results with low complication rates. Superiority of this technique compared with the traditional ones can only be shown with randomized prospective studies. LEVEL OF EVIDENCE: Level III-retrospective cohort study.

INTRODUCTION: Progressive collapsing foot deformity (PCFD), formally known as "adult-acquired flatfoot deformity" (AAFFD), is a complex foot deformity consisting of multiple components. If surgery is required, joint-preserving procedures, such as a medial displacement calcaneal osteotomy (MDCO), are frequently performed. The aim of this systematic review is to provide a summary of the evidence on the impact of MDCO on foot biomechanics. MATERIALS AND METHODS: A systematic literature search across two major sources (PubMed and Scopus) without time limitation was performed according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) criteria. Only original research studies reporting on biomechanical changes following a MDCO were included. Exclusion criteria consisted of review articles, case studies, and studies not written in English. 27 studies were included and the methodologic quality graded according to the QUACS scale and the modified Coleman score. RESULTS: The 27 included studies consisted of 18 cadaveric, 7 studies based on biomechanical models, and 2 clinical studies. The impact of MDCO on the following five major parameters were assessed: plantar fascia (n = 6), medial longitudinal arch (n = 9), hind- and midfoot joint pressures (n = 10), Achilles tendon (n = 5), and gait pattern parameters (n = 3). The quality of the studies was moderate to good with a pooled mean QUACS score of 65% (range 46-92%) for in-vitro and a pooled mean Coleman score of 58 (range 56-65) points for clinical studies. CONCLUSION: A thorough knowledge of how MDCO impacts foot function is key in properly understanding the postoperative effects of this commonly performed procedure. According to the evidence, MDCO impacts the function of the plantar fascia and Achilles tendon, the integrity of the medial longitudinal arch, hind- and midfoot joint pressures, and consequently specific gait pattern parameters.

BACKGROUND: Minimally invasive surgery (MIS) in medial displacement calcaneus osteotomy (MDCO) has been proposed for surgical correction of adult-acquired flat foot deformity (AAFD) to reduce complications of open approaches. The aim of our study is to systematically analyze complications and the clinical and radiological results of MIS- MDCO. METHODS: A systematic review of the English literature was performed on 30th October 2023. Randomized controlled trials and non-randomized trials, cohort studies, case-control studies and case series concerning surgical correction of AAFD with MIS-MDCO and with at least 15 patients were included. Case reports, technical notes, animal or cadaveric studies were excluded. The quality and risk of bias of the studies included were evaluated using GRADE and MINORS systems. Complications rate, clinical and radiological results were inferred from the studies included. RESULTS: Nine articles were included. A total of 501 cases treated with MIS-MDCO were analysed with a mean follow-up of 11.9 ± 5.1 months. The reported wound infection rate was about 3% and sural neuropathy was rated about 1%. Only 4% of the cases required removal of the screw for pain. In the comparative studies (MIS versus Open MDCO), comparable clinical results but with significant differences (P < 0.001) in infection rates (1% versus 14%) and sural neuropathy (2% versus 1%) were observed. CONCLUSION: AAFD correction performed with MIS-MDCO, with the limitation of a poor quality and high risk of bias of the included studies, seems to provide good clinical results and high subjective satisfaction with a lower complication rate compared to open approach. Further high-quality long-term comparative studies could better clarify complications and clinical and radiological outcomes of the MIS technique in the treatment of AAFD. LEVEL OF EVIDENCE: Level IV.

PURPOSE: To compare primary arthrodesis (PA) versus open reduction and internal fixation (ORIF) in displaced intra-articular calcaneal fractures (DIACFs), based on clinical outcome and 2D and 3D geometrical analyses obtained from weight-bearing (WB) cone-beam CT images. MATERIALS AND METHODS: In this prospective study, 40 patients with surgically treated calcaneal fractures were included, consisting of 20 PA and 20 ORIF patients. Weight-bearing cone-beam CT-images of the left and right hindfoot and forefoot were acquired on a Planmed Verity cone-beam CT-scanner after a minimum of 1-year follow-up. Automated 2D and 3D geometric analyses, i.e., (minimal and average) talo-navicular joint space, calcaneal pitch (CP), and Meary's angle (MA), were obtained for injured and healthy feet. Clinical outcomes were measured using the EQ5D and FFI questionnaires. RESULTS: Overall, there were no differences in baseline patient characteristics apart from age (p < 0.005). The calcaneal pitch in 2D after treatment by ORIF (13.8° ± 5.6) was closer to the uninjured side (18.1° ± 5.5) compared to PA (10.9° ± 4.5) (p < 0.001). Meary's angle in 2D was closer to the uninjured side (8.7° ± 6.3) after surgery in the PA cohort (7.0° ± 5.8) compared to the ORIF cohort (15.5° ± 5.9) (p = 0.046). In 3D measurements, CP was significantly decreased for both cohorts after surgery (- 4.09° ± 6.2) (p = 0.001). MA was not significantly affected overall or between cohorts in 3D. Clinical outcomes were not significantly different between the ORIF and PA cohorts. None of the radiographic measurements in 2D or 3D correlated with any of the clinical outcomes studied. CONCLUSION: Three-dimensional WB CT imaging enables functional 2D and 3D analyses under natural load in patients with complex calcaneal fractures. Based on clinical outcome, both PA and ORIF appear viable treatment options. Clinical correlation with geometrical outcomes remains to be established.

OBJECTIVE: To investigate the clinical effect of human acellular dermal matrix (HADM) combined with split-thickness skin graft in repairing lacunar soft tissue defects of the lateral heel after calcaneal fracture. METHODS: From June 2018 to October 2020, providers repaired 11 cases of lacunar soft tissue defects at the lateral part of the heel using HADM combined with split-thickness skin graft. After thorough debridement, the HADM was trimmed and filled into the lacunar defect area. Once the wound was covered, a split-thickness skin graft and negative-pressure wound therapy were applied. Providers evaluated the appearance, scar, ductility of the skin graft site, appearance of the donor site, healing time, and any reoperation at follow-up. RESULTS: Of the 11 cases, 8 patients achieved successful wound healing by primary intention. Three patients showed partial necrosis in the edge of the skin graft, but the wound healed after standard wound care. Evaluation at 6 and 12 months after surgery showed that all patients had wound healing and mild local scarring; there was no obvious pigmentation or scar formation in the donor skin area. The average healing time was 37.5 days (range, 24-43 days). CONCLUSIONS: The HADM combined with split-thickness skin graft is a simple and effective reconstruction method for lacunar soft tissue defect of the lateral heel after calcaneal fracture. In this small sample, the combination demonstrated few infections, minor scar formation, few donor site complications, and relatively short hospital stays.

The objective of this study is to compare the clinical efficacy of percutaneous cannulated screw fixation and traditional plate internal fixation in the treatment of Sanders II and III calcaneal fractures. The records of 64 patients were retrospectively analyzed. Thirty-three cases were fixed by percutaneous cannulated screws. Thirty-one cases were fixed with traditional steel plates. The preoperative preparation time of the screw group and plate group was 3 ± 1.7 days and 4.6 ± 2.1 days. The surgery time was 118.9 ± 43.8 minutes and 146.9 ± 47.6 minutes. The length of hospitalization was 8.7 ± 3.9 days and 17.0 ± 7.9 days. Intraoperative blood loss was 38.2 ± 27.7 mL and 67.1 ± 58.8 mL. The postoperative drainage volume of the plate group was 85.1 ± 53.7 mL, and no wound drainage was needed in the screw group after surgery. Postoperative wound complications occurred in 2 cases of the screw group and 8 cases of the plate group. The recovery effects of Gissane angle and Bohler angle are similar in the 2 groups. The excellent and good rate of the American Orthopaedic Foot and Ankle Society ankle-hindfoot Scale in the screw group was 96.8% at 12 months after surgery, whereas the rate was 93.5% in the plate group. Compared with the traditional plate internal fixation, the percutaneous cannulated screw group achieved a similar excellent and good rate of clinical treatment. It has the advantages of less trauma, less bleeding, low incidence of complications, short preoperative preparation, and hospitalization time.

The Omoto technique is a well-known method that is commonly used for noninvasive manual repair of calcaneal fractures. However, there have been no detailed studies on its clinical outcomes in preoperative closed reduction for surgical cases. This multicenter retrospective study aimed to compare the clinical and radiographic outcomes of calcaneal fractures treated with and without the preoperative Omoto technique, assessing its effectiveness. We extracted 335 patients with calcaneal fracture who underwent surgery between 2015 and 2020 from our multicenter database, named TRON. We evaluated the clinical outcomes using the American Orthopedic Foot and Ankle Society (AOFAS) score, the Böhler angle (BA) for radiographic analysis, and noted any complications. We divided the patients into those managed with the Omoto technique (group O) and those managed without the Omoto technique (group N). Patients were matched by age, sex, and fracture type, resulting in 43 patients per group. The use of the Omoto technique at the time of injury significantly improved the Böhler angle (BA). Furthermore, there were no significant differences in AOFAS, postoperative complications, or BA values at the final follow-up. In conclusion, our study demonstrates that the Omoto technique, when used preoperatively for calcaneal fractures, does not negatively impact the outcomes of subsequent surgical treatments. For patients who prefer to avoid surgery, the Omoto technique can be an effective initial intervention. Additionally, our findings suggest that the Omoto technique may facilitate less invasive surgical options in certain cases.

PURPOSE OF THE STUDY: This manuscript aims to present the method of arthroscopic assisted subtalar arthrodesis and to evaluate the benefi ts of this surgery on our study population. MATERIAL AND METHODS: In the period from 9/2007 to 1/2020, a total of 33 subtalar arthrodesis were performed in 31 patients aged 19-66 years (mean 48 years, median 50 years). The indication for arthrodesis was subtalar arthritis causing pain and gait disorders, or hindfoot deformities (most commonly after a calcaneus bone fracture). The arthroscopic assisted subtalar arthrodesis was performed with autologous tricortical bone block graft harvesting from the pelvis, supplemented by autologous cancellous bone graft. Stabilization was achieved by cannulated screws inserted in neutral ankle position. Patients in our retrospective study were followed up for a mean of 48 months (range, 24-130 months). The patients were evaluated preoperatively and at 2 years after surgery. The hindfoot angles and height (TCA - talocalcaneal angle, CIA - calcaneal inclination angle, TCH - talocalcaneal height) were evaluated on radiographs, bone union was assessed on radiographs and CT scans. The clinical assessment was performed using the ankle-hindfoot scale (AHS) of AOFAS (AOFAS score). RESULTS: The preoperative AOFAS score was 35-68 points (mean 52, median 54), the postoperative AOFAS score at 2 years after arthrodesis was 58-94 points (mean 82, median 82). Both the mean and median values of AOFAS score showed a signifi - cant progress from the poor result to the good and excellent result. After 2 years the TCA value decreased in 18 patients (56%) by no more than 3°. The CIA decrease observed in 21 patients (64%) was by 1° on average. The TCH decrease of 1-5 mm after 2 years since the surgery was seen in 16 patients. In 2 patients incomplete healing of arthrodesis was observed, manifested as a clinically asymptomatic non-union. No deep infection was reported. DISCUSSION: In agreement with the current literature, the arthroscopic subtalar arthrodesis has been confi rmed to be a safe method for the management of consequences of hindfoot fractures, with minimum complications and leading to accelerated bone fusion. Differences can be found in the approach, position, use of cancellous bone graft and surgical techniques. In recent years, prone position, posterior approaches, use of cancellous bone graft, distraction and fi xation with 2-3 screws divergently inserted into the bone prevail. The degree of healing of the bone fusion is generally an important factor. In our study population, non-healing was recorded in 2 patients, namely in the form of a clinically silent non-union. Neurological or early complications and/or osteosynthesis material failure occurred in up to a maximum of 10% of cases. The conclusive results of minimally invasive arthrodesis based on the AOFAS score have been confi rmed by us as well as by most authors. CONCLUSSIONS: Our study confi rmed that the arthroscopic assisted subtalar arthrodesis is a successful, reliable and safe minimally invasive method, with minimum complications, leading to stable arthrodesis. KEY WORDS: subtalar arthrodesis, subtalar arthroscopy.

BACKGROUND: The objective was to compare postoperative complications in the management of displaced intra articular calcaneal fractures (DIACF) between two groups; the open reduction and internal fixation (ORIF) group versus the percutaneous fixation (PF) group. METHODS: A total of 243 DIACFs were diagnosed and 127 of them received operations either with ORIF 75 (59.1 %) or PF 52 (40.9 %) between 2004 and 2018. Postoperative complications, radiological Sanders's classification and improvement of Böhler's angle were analyzed. RESULTS: Early complication rate (<6 weeks), rate of deep wound infections and wound edge necrosis were significantly better in PF than in ORIF patient group. There were no significant differences in late complications (>6 weeks from operation) nor in improvement of Böhler's angle. CONCLUSION: Complication rate is lower when using PF technique while fracture reduction remains the same compared to the ORIF. LEVEL OF EVIDENCE: IV retrospective cohort study at a single institution.

BACKGROUND: Insertional Achilles tendinopathy (IAT) is a common pathology with multiple surgical interventions available for treatment. The Zadek, dorsal closing wedge calcaneal osteotomy (ZO) has been demonstrated to be effective treatment of IAT. There have been various recommendations in the literature as to what measurement of wedge removal should be considered ideal to produce greatest postoperative range of motion (ROM), thus postoperative biomechanical potential. Accordingly, the purpose of this cadaveric study was to assess the range of motion achieved after various measurements of wedge removal by ZO. METHODS: The ZO was performed on six cadaveric specimens. A 7.5 mm and 15 mm wedge osteotomy was marked and sequentially completed on each specimen. Lateral fluoroscopic imaging was utilized to take preoperative and postoperative ROM measurements for each osteotomy. Dorsiflexion (DF) and plantarflexion (PF) ROM arcs were measured for each wedge size and compared by t-test. Effect sizes were calculated by Cohen's d analysis. RESULTS: Maximal DF was 110.87 ± 12.97 deg in the pre-osteotomy state. Removal of a 7.5 mm wedge improved DF by 8 deg to a mean 102.93 ± 13.81 deg (p = 0.08). Removal of a 15 mm wedge improved DF by 16 deg to a mean 95.96 ± 11.41 deg (p = 0.003). Cohen's d and effect size calculation demonstrated a 7.5 mm wedge to have a small effect on DF, while a 15 mm wedge had a medium effect (0.29, 0.52 respectively). Maximal PF did not change significantly amongst the pre-osteotomy, 7.5 mm wedge, or 15 mm wedge positions. ICC was 0.96. CONCLUSION: Based on the results presented in this study, removal of a 15 mm wedge with ZO yields significant and greater improvement in ROM than a 7.5 mm wedge. We hope the current study will better inform preoperative planning for ZO. STUDY TYPE: Prospective Cadaver Study. LEVEL OF EVIDENCE: V.

BACKGROUND: Calcific insertional Achilles tendinopathy(CIAT) with Haglund deformity is a type of recalcitrant tendinopathy. The necessity of concomitant removal of Haglund deformity during CIAT treatment is controversial. The present study aimed to evaluate the functional outcomes between Haglund resection and Haglund non-resection in the treatment of CIAT with Haglund deformity. METHODS: A retrospective study included 29 patients who were underwent Achilles tendon debridement, bursal excision, and subsequent tendon reattachment.for CIAT with Haglund deformity. All patients were divided into 2 groups according to Haglund resection (resection group, n = 16) and Haglund non-resection (non-resection group, n = 13) using the parallel line method on lateral calcaneal X ray after surgery. Patients were evaluated in terms of the American Orthopedic Foot and Ankle Society (AOFAS), Visual Analog Scale (VAS) and Victorian Institute of Sports Assessment-Achilles (VISA-A) scores and the mean time of activities of daily living (ADL). Anatomy changes included the Fowler-Philip angle, calcaneal pitch angle and Achilles tendon force arm were measured with radiography preoperatively and postoperatively. RESULTS: Both groups exhibited a significant increase in AOFAS, VAS and VISA-A scores after surgery. There were no significant differences between the resection group and the non-resection group for the AOFAS (92.38 ± 5.7 vs. 93.15 ± 12.17; P = 0.82), VAS (0.5 ± 0.52 vs. 0.61 ± 0.87; P = 0.66) and VISA-A questionnaire (82.56 ± 13.46 vs. 74.92 ± 16.4; P = 0.18) at the latest follow-up. The mean time of ADL in the non-resection group was significantly faster compared to that of the resection group (8.15 ± 2.51 weeks vs. 11.31 ± 4.06 weeks, P = 0.02). The Fowler-Philip angle of the resection group decreased from 55.55° ± 12.34° preoperatively to 44.52° ± 10.24° at the latest follow-up (P = 0.001). The Fowler-Philip angle of the non-resection group decreased from 54.38° ± 8.41° preoperatively to 46.52° ± 8.02° at the latest follow-up (P = 0.016). The calcaneal pitch angle of the resection group increased from 22.76° ± 5.37° preoperatively to 25.98° ± 6. 4° at the latest follow-up (P = 0.018). The Achilles tendon force arm of the resection group decreased from 178.50 mm ± 5.37 mm preoperatively to 173.90 mm ± 8.07 mm at the latest follow-up (P = 0.018). CONCLUSION: Resection or non-resection of the posterosuperior calcaneal tuberosity for CIAT with Haglund deformity would both provide satisfactory functional outcomes. Haglund non-resection may expedite patients' return to their daily activities, suggesting a Haglund deformity resection may be unnecessary in the surgical treatment for CIAT with Haglund deformity.

Talocalcaneal coalitions (TCC) is the second most frequent tarsal coalition reported. Our aim was to review talocalcaneal coalition classifications and to propose a new classification emphasizing a therapeutic approach. None of the classifications described for TCC mention the presence of flatfoot or valgus hindfoot, which are the key elements when defining the optimal treatment of this disease. We defined five clinical and radiological factors that would guide the choice of surgical treatment and based on these, we proposed a new classification system.

OBJECTIVES: To present a review of the clinical characteristics, preoperative and surgical management, and outcomes of patients with intra-articular calcaneal fractures who had open reduction and internal fixation (ORIF) and to offer some comments on and research ideas for the preoperative management of patients with these fractures. PATIENTS AND METHODS: We studied consecutive patients who had ORIF performed by a single surgeon for closed, intra-articular calcaneal fractures at our level-1 trauma center between 5/29/2012 and 3/20/2018. All inpatients were treated with a preoperative soft tissue management protocol, whereas outpatients were not. Data were obtained about demographic and clinical characteristics, times from injury to surgery, quality of fracture reductions, and complication rates. RESULTS: Mean follow-up for the 72 patients with 77 calcaneal fractures was 8.5 (range: 1-43) months, and 21 (27.3%) fractures received inpatient preoperative care with a soft tissue management protocol, while 56 (72.7%) received outpatient preoperative management. More of the fractures treated preoperatively as inpatients versus outpatients were classified as Sanders type III (66.7% vs. 32.1%) and type IV (8.9% vs. 4.8%) fractures and were associated with polytrauma (38.1% vs. 7.1%) and diabetes mellitus (9.5% vs. 5.4%), respectively. For all patients, the mean time from injury to surgery was 12.2 (range: 2.7-19.4) days, and the time was 6.3 days for inpatients and 14.4 days for outpatients, but the quality of fracture reductions and complication rates did not differ between these two groups. CONCLUSIONS: Patients with intra-articular calcaneal fractures treated as inpatients and receiving a preoperative soft tissue management protocol had outcomes after ORIF that were not inferior to those experienced by patients treated preoperatively as outpatients, despite a greater proportion of the inpatients having severe fractures, polytrauma, and diabetes mellitus. Dedicated preoperative soft tissue management protocols may be beneficial for patients with calcaneal fractures and warrant further study.

PURPOSE: Tarsal tunnel syndrome is well documented following lateralizing calcaneal osteotomy to manage varus hindfoot deformity. Traditionally, calcaneal osteotomy is performed with an oscillating saw. No studies have investigated the effect of alternative surgical techniques on postoperative tarsal tunnel pressure. The purpose of this study was to investigate the difference in tarsal tunnel pressures following lateralizing calcaneal osteotomy performed using a high-torque, low-speed "minimally invasive surgery" (MIS) Shannon burr versus an oscillating saw. METHODS: Lateralizing calcaneal osteotomy was performed on 10 below-knee cadaveric specimens. This was conducted on 5 specimens each using an oscillating saw (Saw group) or MIS burr (Burr group). The calcaneal tuberosity was translated 1 cm laterally and transfixed using 2 Kirschner wires. Tarsal tunnel pressure was measured before and after osteotomy via ultrasound-guided percutaneous needle barometer. Mean pre/post-osteotomy pressures were compared between groups. Differences were analyzed using Student's t test. RESULTS: The mean pre-procedure tarsal tunnel pressure was 25.8 ± 5.1 mm Hg in the Saw group and 26.4 ± 4.3 mm Hg in the Burr group (p = 0.85). The mean post-procedure pressure was 63.4 ± 5.1 in the Saw group and 47.8 ± 4.3 in the Burr group (p = 0.01). Change in tarsal tunnel pressure was significantly lower in the Burr group (21.4 ± 4.5) compared to the Saw group (37.6 ± 12.5) (p = 0.03). The increase in tarsal tunnel pressure was 43% lower in the Burr group. CONCLUSION: In this cadaveric study, tarsal tunnel pressure increase after lateralizing calcaneal osteotomy was significantly lower when using a burr versus a saw. This is likely because the increased width ("kerf") of the 3 mm MIS burr, compared to the submillimeter saw blade width, causes calcaneal shortening. Given the smaller increase in tarsal tunnel pressure, using the MIS burr for lateralizing calcaneal osteotomy may decrease the risk of postoperative tarsal tunnel syndrome. Future research in vivo should explore this.

INTRODUCTION: Calcaneus is the most commonly fractured tarsal bone. Open reduction and internal fixation of the displaced intra-articular fractures is considered the gold standard treatment. The lateral extensile approach is the most commonly used approach, and usually, the patients are kept in lateral decubitus position. Recent study has descried calcaneus fracture fixation utilizing the lateral extensile approach with the patient in prone position. The aim of this study was to compare the postoperative radiological outcome, reoperation rate, operative and anesthesia time, infection and the wound complications rate between the two groups. METHODS: The data of 49 adult patients with unilateral closed calcaneus fracture underwent open reduction and internal fixation using lateral extensile approach were collected. Postoperative Bohler's, Gissane angles and complications rate were compared between the two groups. RESULTS: A total of 49 patients were included. Lateral position was utilized in 26 patients (53.1%), while 23 patients (46.9%) were operated in prone position. Majority of the patients were males 87.8% (43 patients), and the mean age of the patients was 31.12 ± 7.50. The most commonly mechanism of injury was fall from height in (91.8%) of the patients. The mean preoperative Bohler's angle was 9.33 ± 13.07 and increased to 22.69 ± 9.15 postoperatively. The mean preoperative angle of Gissane was 130.45 ± 26.98 whereas it was 124.76 ± 17.20 postoperatively. The mean postoperative Bohler's angle and angle of Gissane were significantly higher among patient who underwent fixation in lateral position (25.88 ± 6.62, 137.15 ± 11.17) when compared to the prone one (19.09 ± 10.35, 110.74 ± 10.81). There was no significant difference between the two groups regarding the reoperation rate (p 0.947), infection (p 0.659, operative time (p 0.688), anesthesia time (p 0.522) and wound complications (p 0.773). CONCLUSION: Surgical restoration of the Bohler's and Gissane's angles with the patient placed in the lateral decubitus position remains superior to the prone position with no difference in the complication rate between the two groups.

BACKGROUND: Increased posterior wall acetabular fractures among older adults, require precise treatment to restore stability to the joint, lower the risk of degenerative arthritis, and enhance overall functional recovery. The purpose of this study was to compare the fixation stability and mechanical characteristics of calcaneal buttress plate and conventional reconstruction plate under different loading condition. METHODS: Typical acetabular posterior wall fractures were created on twenty synthetic hemipelvis models. They were fixed with calcaneus plate and reconstruction plate. Dynamic and static tests were performed. Displacements of fracture line and stiffness were calculated. FINDINGS: After dynamic loading, calcaneus plate fixation has significantly less displacement than the reconstruction plate on the superior posterior wall. Under static loading condition, the calcaneus plate group has significantly less displacement than the reconstruction plate group on the inferior posterior part of the fracture. The average stiffness values of the calcaneus plate group and the reconstruction plate group were 265.16±53.98 N/mm and 167.48±36.87 N/mm, respectively and a statistically significant difference was found between the two groups. INTERPRETATION: The calcaneal plate group demonstrated better stability along the fracture line after dynamic and static loading conditions. Especially when the fragment was on the acetabulum's superior posterior, inferior posterior, and inferior rim, Calcaneal buttress plates offer biomechanically effective choices.

OBJECTIVE: Traditional internal fixation of calcaneus fractures, involving lateral L-shaped incisions and plate fixation, has disadvantages such as increased operative exposure, eccentric plate fixation, and complications. The aim of this study was to design a Spatial Weaving Intra-calcaneal Fixator System (SWIFS) for the treatment of complex calcaneal fractures and to compare its biomechanical properties with those of traditional calcaneal plates. METHODS: The computed tomography (CT) data of the normal adult calcaneus was used for modeling, and the largest trapezoidal column structure was cut and separated from the model and related parameters were measured. The SWIFS was designed within the target trapezoid, according to the characteristics of the fracture of the calcaneus. The Sanders model classification type IV calcaneal fracture was established in finite element software, and fixation with calcaneal plate and the SWIFS examined. Overall structural strength distribution and displacement in the two groups were compared. RESULTS: The maximum 3D trapezoidal column in the calcaneus was constructed, and the dimensions were measured. The SWIFS and the corresponding guide device were successfully designed. In the one-legged erect position state, the SWIFS group exhibited a peak von Mises equivalent stress of 96.00 MPa, a maximum displacement of 0.31 mm, and a structural stiffness of 2258.06 N/mm. The conventional calcaneal plate showed a peak von Mises equivalent stress of 228.66 Mpa, a maximum displacement of 1.26 mm, and a structural stiffness of 555.56 N/mm. The SWIFS group exhibited a 75.40% decrease in displacement and a 306.45% increase in stiffness. CONCLUSION: Compared with fixation by conventional calcaneal plate, the SWIFS provides better structural stability and effective stress distribution.
