Minimally invasive surgery for intra-articular calcaneus fractures: a 9-year, single-center, retrospective study of a standardized technique using a 2-point distractor.

ABSTRACT: BACKGROUND:A fracture of the calcaneus can be a painful and disabling injury. Treatment modalities may be conservative or operative. Surgical treatment strategies include open reduction and internal fixation (ORIF) techniques, as well as a variety of minimally invasive methods. The aim of this study was to evaluate the treatment options and post-treatment complication rates for intra-articular calcaneal fractures at the Traumacenter Linz over a 9-year period. METHODS:All patients with calcaneal fractures treated at the Traumacenter Linz between 2007 and 2015 were included in this study. The patients records were retrospectively reviewed, and the data, including demographic parameters, cause of injury, and the time between injury and operative treatment were analyzed. The number of secondary operative interventions due to soft-tissue complications, hardware removal, and the long-term arthrodesis rate were evaluated. RESULTS:A minimally invasive 2-point-distractor method was used in 85.8% (n =?182) of all operatively managed calcaneal fractures (n =?212) in our department. The majority of the operations (88.7%) were performed within 2 days after the accident. The secondary operation rate resulting from wound complications was 2.7% in the 2-point distractor group and 16.7% in the ORIF group. A secondary arthrodesis was performed in 4.7% (n =?9) of the subtalar joints in the entire study population. CONCLUSIONS:Our data supported the assumption that severe wound complications would be less likely to occur after minimally invasive treatment compared to ORIF treatment. The rate of secondary arthrodesis in the study cohort was comparable to that in the literature. LEVEL OF EVIDENCE:IV.

Project description:BackgroundThe Calcaneus is the largest bone of the foot and the most frequent tarsal bone to be fractured. Overall, it causes round about 10 cases per 100,000 residents per year mainly in men. Especially displaced intra-articular calcaneus fractures often have early and late complications and its associated disability. There are various strategies for the treatment of displaced intra-articular calcaneus fractures, but the gold standard is still subject of a long-standing controversy. Minimally invasive procedures became more common in an attempt to reduce the high rate of complications associated with open reduction and internal fixation. With the increase in minimally invasive techniques, screw fixation also gained in significance. The current literature does not sufficiently elucidate whether the screw fixation is superior to other treatment options especially in relation to adverse events, health-related quality of life and postoperative pain. This study aims to investigate benefits and harms of treating displaced intra-articular calcaneus fractures (types II, III and IV according to Sanders) with screw fixation in adults.MethodsA systematic review will be conducted based on the principles described in the Cochrane Handbook. We will include adults with displaced intra-articular calcaneus fractures of Sanders type II, III and IV. The surgical method of screw fixation shall be compared to other surgical interventions to stabilise calcaneus fractures. Primary outcomes are serious adverse events, health-related quality of life and postoperative pain level. MEDLINE, CENTRAL, CINAHL, Web of Science and bibnet.org, ClinicalTrial.gov and the World Health Organization International Clinical Trials Registry Platform (ICTR) will be searched. Screening and data extraction will be performed by two authors independently. A third author will arbitrate disputes. Risk of Bias will be assessed with the Cochrane tool. Meta-analysis will be performed if participants, interventions, comparisons and outcomes are sufficiently similar to ensure a result that is clinically meaningful.DiscussionDue to the increasing use of minimally invasive techniques and the increasing use of screw fixation instead of open reduction and plate fixation, it is important to analyse the benefits and harms of screw fixation for calcaneus fractures. Screw fixation could, in the future, help to operate in a less invasive and tissue preserving manner while still achieving an adequate functional result for the patient SYSTEMATIC REVIEW REGISTRATION: CRD42021244695.

Project description:ObjectivesTo quantify fracture severity for a series of displaced intra-articular calcaneal fractures (DIACFs) and to correlate it with Sanders classification, post-traumatic osteoarthritis (PTOA), and patient outcomes.DesignRetrospective review and fracture severity analysis.SettingLevel 1 trauma center affiliated with the University of Iowa in Iowa City, IA.Patients/participantsThirty-six patients with 48 DIACFs were selected from 153 patients previously treated. All patients 18 years of age and older who had available electronic preop and postop computed tomography (CT) scans, good-quality postop and follow-up radiographs, and a follow-up ≥18 months were selected for study.InterventionFractures were treated with percutaneous reduction, using multiple small stab incisions and fluoroscopy to guide manipulation of articular fragments using cork screws or Steinmann pins, with subsequent fixation using 3.5- and 4.0-mm screws.Main outcome measurementsPreop CT scans were used to grade fractures according to the Sanders classification and to quantify fracture severity. Fracture severity was objectively quantified using a CT-based measure of fracture energy. PTOA was assessed on follow-up radiographs using the Kellgren-Lawrence scale. Patient outcomes were assessed using the Short Form 36 (SF-36) questionnaire and a visual analog scale pain score.ResultsFracture energies for the 48 DIACFs ranged from 14.1 to 26.2 J (19.3 ± 3.1 J) and correlated with Sanders classification (rho = 0.53, P = 0.0001); type I (16.3 ± 0.9 J); type II (18.0 ± 2.7 J); type III (20.8 ± 2.8 J); and type IV (22.0 ± 0.7 J). Fracture energy was higher for fractures in which the subtalar joint developed PTOA (19.5 ± 2.7 J) than for those that did not (18.9 ± 3.3 J), but the difference did not reach statistical significance. The Sanders classification predicted PTOA risk [odds ratio (OR) = 4.04, 95% confidence interval = 1.43-11.39, P = 0.0084]. No relationship was observed between fracture energy and visual analog scale pain scores. Higher fracture energy correlated with lower SF-36 scores.ConclusionsFracture energy positively correlates with Sanders classification for DIACFs, which can be used to identify more severe fractures at greater risk of progressing to PTOA.Level of evidencePrognostic Level III.
