Arthroscopic Management of Sinus Tarsi Syndrome.

ABSTRACT: Sinus tarsi syndrome (STS) is a clinical entity characterized by pain of the lateral hindfoot and a sense of instability especially on uneven surfaces due to chronic inflammation characterized by fibrotic tissue remnants and synovitis of the sinus tarsi, associated with both traumatic and nontraumatic causes. Arthroscopic debridement of the subtalar joint is an effective and safe alternative in the treatment of STS refractory to conservative treatment. The purpose of this Technical Note is to report the details of arthroscopic management of STS.

Project description:BackgroundCalcaneal fractures are the most common tarsal bone fracture, and are often accompanied by heel pain, local swelling, tenderness, and inability to walk or stand. Surgical intervention results in better reconstruction of the calcaneal anatomy and reduces future complications; however, the optimal incision approach is still controversial. The incision is exposed better with extensile lateral approach (ELA), while the sinus tarsi approach (STA) causes fewer complications. The purpose of this meta-analysis is to compare the outcomes of STA and ELA.Materials and methodsPublished trials comparing ELA and STA in calcaneal fractures were included in our analysis. The quality of each study was assessed using the revised Jadad scale and the Newcastle-Ottawa scale. Two researchers (CP and BY) independently extracted data from all selected studies. Fixed- or random-effects models with mean differences and odds ratios were used to pool the continuous and dichotomous variables to determine the heterogeneity of the included studies.ResultsCalcaneal height and calcaneal width had high heterogeneity. Results showed that the incidence of incision complications in STA was lower than that in ELA (P < .001). There was high heterogeneity in operative time (I2 = 97%), length of hospital stay (I2 = 98%), Böhler angle (I2 = 80%), Gissane angle (I2 = 98%), and American Orthopaedic Foot & Ankle Society scores (I2 = 73%). No source of heterogeneity was found by sensitivity analysis, subgroup analysis, or regression analysis, and the random-effects model was used. STA operative time was significantly shorter than ELA (P < .001). Length of hospital stay after STA was significantly shorter than after ELA (P = .002). There was no statistical difference in the Böhler and Gissane angles between STA and ELA. Postoperative American Orthopaedic Foot & Ankle Society scores after STA were higher than after ELA (P = .01).ConclusionsResults show that, compared with ELA, STA is superior for treating calcaneal fractures due to anatomical reduction of the calcaneus, reduction of incision complications incidence, and shortened operative time and postoperative stay.

Project description:BackgroundThis study sought to assess and compare the clinical efficacy and complications of a modified sinus tarsi approach (MSTA) and the extensile lateral approach (ELA) in the treatment of displaced intra-articular calcaneal fractures.MethodsThis retrospective study enrolled 108 patients (117 feet) with Sanders II-IV calcaneal fractures, including 52 patients (56 feet) in the MSTA group and 56 patients (61 feet) in the ELA group. The functional and radiological results of the affected feet were analysed retrospectively. Functional evaluation included American Orthopaedic Foot and Ankle Society (AOFAS), visual analog scale (VAS), and Short Form-36 Health Survey (SF-36). Radiological evaluation included preoperative and postoperative changes in the Bohler Angle, Gissane Angle, length, width, and height of the calcaneus. The postoperative complications were also collected and analysed. The independent-samples t-test and analysis of variance (ANOVA) were employed to compare differences between the two groups. Differences within the same group were compared by paired Student's t-test, and categorical variables were compared using the chi-square test.ResultsThe postoperative functional and radiological results showed that the mean AOFAS, VAS and physical component summary of SF-36 scores in the MSTA group were higher than those in the ELA group (P<0.05). After surgery, the Bohler and Gissane angles were significantly improved in both groups, as were the length, width, and height of the calcaneus; no statistically significant differences existed between the two groups. The incidences of wound healing complications and postoperative sural nerve injury were lower in the MSTA group than in the ELA group (P<0.000).ConclusionsThe MSTA can achieve similar effects to the ELA in terms of anatomical reconstruction and functional recovery. It also can also effectively reduce the incidences of wound healing complications and postoperative sural nerve injury, and shorten the length of hospital stay.

Project description:Calcaneum is the most commonly fractured tarsal bone. The optimal treatment for displaced calcaneus fractures involving the posterior facet is surgical. The extensile lateral approach is commonly preferred because it provides sufficient exposure of the subtalar facet. However, this technique has the risk of complications such as wound necrosis and sural nerve injury. Various minimally invasive approaches, such as sinus tarsi approach, limited posterior approach, and percutaneous approach, have been introduced to reduce possible complications. This study was prospectively performed to evaluate the results of the sinus tarsi approach for Sanders Type 2 calcaneal fractures using postoperative computed tomography (CT).Between October 2012 and December 2013, 20 Sanders Type 2 calcaneal fractures were consecutively treated using a sinus tarsi approach and checked using CT preoperatively, immediately postoperatively, and at 12 months after surgery. Clinical evaluations were performed using the visual analog scale (VAS) and the ankle-hindfoot score developed by the American Orthopaedic Foot and Ankle Society (AOFAS). Radiographic evaluations were performed using calcaneus lateral and axial radiographs, hindfoot alignment radiograph, and CT. Changes in Böhler's angles and calcaneal widths were evaluated both preoperatively and at last followup. Reduction of the posterior facet was graded according to articular step, defect, and angulation of the posterior facet in CT.VAS and AOFAS scores were significantly improved at 1 year after surgery but did not improve further. Böhler's angles and calcaneal widths were significantly improved after surgery. Böhler's angle was significantly smaller at the last followup than immediately after surgery, whereas calcaneal width was maintained. Reduction of the posterior facet was graded excellent in five feet (25%), good in ten (50%), and fair in five (25%) on immediately postoperative CT. Two feet (10%) had transient sural nerve injury which resolved within 3 months. Five feet (20%) had subfibular pain due to a prominent screw heads.Surgical management using a sinus tarsi approach produced good clinical and radiographic results and low wound complications for Sanders type 2 calcaneal fractures. It is important to have stable fixation and to achieve sufficient reduction of calcaneal width for the prevention of loss of reduction and lateral subfibular impingement.

Project description:BACKGROUND:Sinus tarsi approach and mini-calc plate have been used for intra-articular calcaneal fractures. However, the sinus tarsi approach has limited exposure to the lateral wall, which makes it challenging to obtain an excellent anatomic reduction of the calcaneal body. What is more! To restore the width of the calcaneal body entirely and prevent the heel varus simultaneously with mini-calc plate was tough as well. Aimed to solve the aforementioned problems, our study focused on using the Steinmann pin retractor for reduction and the circle plate for fixation via the sinus tarsi approach. METHODS:From March 2017 to January 2019, 15 patients with closed calcaneal fractures were treated with the method of Steinmann pin retractor-assisted reduction and circle plate fixation via the sinus tarsi approach. All these patients received a positive postoperative clinical and radiological evaluation. RESULTS:A postoperative follow-up was done for each of the 15 patients, and the following scores and parameters were observed: value of visual analogue scale (VAS) was 1.44 ± 0.63, and The American Orthopaedic Foot and Ankle Score (AOFAS) Ankle-Hindfoot score was 84.31 ± 5.03 at the last follow-up. The Böhler angle (30.81 ± 3.56°), width (37.83 ± 4.87 mm), length (87.4 ± 3.33 mm), and height (86.23 ± 5.36 mm) of the calcaneus were improved significantly in comparison with preoperative values (- 0.94 ± 10.06°, 45.67 ± 5.68 mm, 82.72 ± 5.54 mm, 76.32 ± 7.98 mm), and these parameters were maintained excellently after 6-19 months' follow-up. CONCLUSION:Our present study suggested that Steinmann pin retractor-assisted reduction with circle plate fixation via the sinus tarsi approach may serve as a safe and effective method for Sanders type II and type III calcaneus fractures. The Böhler angle, height, length, and body of the calcaneus were excellently restored postoperatively and maintained at last follow-up and rare postoperative complications.
