The Use of Modified Ollier Approach and Structural Allograft for Fixation of Intra-articular Calcaneal Fractures

Background: Severely displaced calcaneal fractures can result in considerable morphology derangement and may be accompanied by soft tissue compromise. Delayed operative restoration of the calcaneal morphology may result in acute retensioning of the damaged soft tissue with associated wound-related complications. In this study, we describe a staged treatment of displaced intra-articular calcaneal fractures that uses temporary transarticular Kirschner wire (K-wire) fixation and staged conversion to definite fixation. Methods: We identified all of the patients who were treated at our institution for calcaneal fractures between 2015 and 2019. A total of 17 patients with 20 calcaneal fractures were selectively treated with 2-stage management. Temporary transarticular K-wire fixation was performed 24 hours after the injury to restore calcaneal morphology and the surrounding soft tissue. After the soft tissue was considered safe, delayed open reduction and internal fixation was performed. The time to definite surgery, radiographic alignment, wound complications, time to radiographic union, and hindfoot American Orthopaedic Foot & Ankle Society (AOFAS) scores were recorded. Results: The average follow-up period was 17 months (range, 12-43). The average Böhler angle increased from a mean of −22 degrees (range, −109 to 25) to 25 degrees (range, 0 to 47) after temporary transarticular K-wire fixation. The mean time from temporary pinning to conversion to definite internal fixation was 20 (range, 10-32) days. There were no immediate postoperative complications. The average time to radiographic union was 13.7 (range, 10-16) weeks. The mean AOFAS score was 87 (range, 55-100). No infections or wound complications were reported during the follow-up period. Conclusion: Temporary transarticular pinning for staged calcaneal fracture treatment is safe and effective in restoring the calcaneal morphology. This novel and relatively simple method may facilitate delayed operation and decrease wound-related complications. Level of Evidence: Level IV, retrospective case series.

The Impact

Abstract BACKGROUND Although advances in implant materials, such as polyetheretherketone (PEEK), have been developed aimed to improve outcome after anterior cervical discectomy and fusion (ACDF), it is essential to confirm whether these changes translate into clinically important sustained benefits. OBJECTIVE To compare the radiographic and clinical outcomes of patients undergoing up to 3-level ACDF with PEEK vs structural allograft implants. METHODS In this cohort study, radiographic and symptomatic nonunion rates were compared in consecutive patients who underwent 1 to 3 level ACDF with allograft or PEEK implant. Prospectively collected clinical data and patient-reported outcome (PRO) scores were compared between the allograft and PEEK groups. Regression analysis was performed to determine the predictors of nonunion. RESULTS In total, 194 of 404 patients met the inclusion criteria (79% allograft vs 21% PEEK). Preoperative demographic variables were comparable between the 2 groups except for age. The rate of radiographic nonunion was higher with PEEK implants (39% vs 27%, P = .0035). However, a higher proportion of nonunion in the allograft cohort required posterior instrumentation (14% vs 3%, P = .039). Patients with multilevel procedures and PEEK implants had up to 5.8 times the risk of radiographic nonunion, whereas younger patients, active smokers, and multilevel procedures were at higher risk of symptomatic nonunion. CONCLUSION Along with implant material, factors such as younger age, active smoking status, and the number of operated levels were independent predictors of fusion failure. Given the impact of nonunion on PRO, perioperative optimization of modifiable factors and surgical planning are essential to ensure a successful outcome.

Minimally Invasive Reduction

Background Several minimally invasive techniques were developed for management of intraarticular calcaneal fractures. This study aimed to compare the functional and radiological outcomes of 2 minimally invasive reduction and fixation techniques using cannulated screws or Kirschner wires (K-wires) for fixation. Methods This study was a retrospective comparative review of patients with displaced intraarticular calcaneal fractures, who were treated with cannulated screws or K-wires techniques. Clinical and radiological data were collected and compared between both groups. Functional outcomes and patient satisfaction using the Maryland Foot Score (MFS) and the visual analogue scale (VAS) of pain, in addition to the complications, were compared between both groups. Results In total, 70 patients were included in the study: 34 in the cannulated screws group, with a mean age of 35.2 ± 4 years, and 36 in the K-wires groups, with a mean age of 33.4 ± 3 years. The operative time was shorter in the K-wires group (40.5 ± 5.6 minutes) compared to the cannulated screw group (49.5 ± 4.5 minutes), P < .001. There were no statistically significant differences between both groups regarding the radiological parameters, including Bohler’s angle, angle of Gissane, calcaneal width, height, or length. The mean MFS, mean VAS, and complications were not different between the 2 groups. Conclusion Treatment of displaced intraarticular calcaneal fractures with minimally invasive reduction and fixation using either cannulated screws or K-wires can achieve similar excellent functional and radiological outcomes, with high patient satisfaction. The use of K-wires has the advantage of reduced operative time than cannulated screws. Levels of Evidence: Level III: Retrospective comparative study
