Ankle arthrodesis through minimally-invasive transfibular approach: a new surgical technique.

PURPOSE: The purpose of our work was to demonstrate the surgical technique of ankle arthrodesis using the minimally-invasive transfibular (MITF) approach, which minimizes soft tissue damage and is advantageous for high-risk patients. METHODS: In this prospective study, a total of 12 patients with end-stage varus ankle osteoarthritis, including high-risk individuals, underwent ankle arthrodesis using the MITF approach. The technique involves a unique osteotomy at the joint space level, minimizing soft tissue detachment from the fibula. The primary outcomes assessed included bony union, time to weight-bearing, correction of varus deformity, and functional outcomes measured by the American Orthopedic Foot and Ankle Society (AOFAS) hindfoot scale. However, the study's limitations encompass a small sample size and the absence of a control group. RESULTS: At 6 months post-operation, all patients achieved bony union, with a mean time to union of 13.7 ± 5.2 weeks. The average time to initiate weight-bearing without additional support was 11.2 ± 3.8 weeks. Preoperative varus deformity (17.08 ± 8.36 degrees) and talar tilt (8.75 ± 4.33 degrees) were successfully corrected, with postoperative alignment within 0-5 degrees of valgus. Functional outcomes showed a significant improvement in AOFAS scores from 37.83 ± 7.79 points preoperatively to 77.42 ± 5.63 points one year after surgery (p = 0.002). Minor complications occurred in two patients, both effectively treated with local therapy and antibiotics. CONCLUSIONS: The MITF approach for ankle arthrodesis demonstrates promising results in addressing end-stage varus ankle osteoarthritis, even in high-risk patients. However, the study's limitations highlight the need for a prospective comparative clinical trial with a larger sample size to ascertain the technique's effectiveness and safety definitively.

Universal Long Bone Nonunion Classification.

Aim and background: The management of bone union disorders is a complex problem in orthopaedics, requiring a reliable and comprehensive classification system for accurate diagnosis and treatment. Despite advances in understanding pathophysiology, diagnosis, and treatment in this area, there is no generally accepted classification system. The aim of our work was to create a comprehensive classification, which will systemize the vast majority of bone union disorders, underline their differences and form the basis for their treatment. Methods: The key criteria for nonunion evaluation and treatment were identified based on the conducted literature review: Time from the initial event (delayed union or nonunion), location, type of pathology (A, Hypertrophic; B, Normotrophic; C, Oligotrophic) and the presence of hardware. Based on these criteria the ULBNC has been developed. Atrophic nonunions were excluded from this classification as they are considered segmental bone defects with special classification. Results: The ULBNC is based on the same principles of coding as the "gold standard" AO/OTA Fractures Classification system with alpha-numeric coding "from simple to complex." The choice of treatment method depends on the type, group, and subgroup of the nonunion as described. Conclusion: Universal Long Bone Nonunion Classification (ULBNC) is an alphanumeric system that describes the localization, type of pathology and morphologic characteristics of a nonunion. The use of ULBNC in practice and research will optimize and standardize the treatment of various types of bone healing disorders and eventually improve clinical outcomes.

Short-term outcomes of the supine muscle-sparing anterolateral versus direct lateral approach to primary total hip arthroplasty.

BACKGROUND: Although total hip arthroplasty (THA) is among the most successful orthopaedic procedures, it is not without complications. As such, finding the optimal surgical approach has become an area of particular interest. In this study, we compare: (1) pain intensity; (2) opioid consumption; (3) lengths of stay (LOS); (4) complication rates; (5) discharge destination; and (6) ambulatory function between patients who underwent THA via the supine muscle-sparing anterolateral (MS-ALA) and conventional direct lateral (DLA) approaches. METHODS: A retrospective analysis was conducted on 220 consecutive patients who received primary THA using the supine MS-ALA (n = 101) or DLA (n = 119) between 1 January 2014 and 31 December 2016. Outcomes included postoperative pain intensity, opioid consumption, LOS, discharge destination, complications, additional procedures, and time to independent ambulation. RESULTS: We demonstrated significantly lower opioid consumption on postoperative days (POD) 1 and 2 (mean differences, -32.0 and -28.4 mg, respectively; p ⩽ 0.001) and decreased pain intensity during the second 24 hours of the hospital stay (mean difference, -22.0; p < 0.001) in patients receiving the MS-ALA. Relative to the DLA cohort, patients in the MS-ALA cohort were 2.04 times more likely to be discharged to home (p = 0.028) and 1.91 times less likely to experience postoperative abductor insufficiency (p = 0.039). CONCLUSION: The present study is the 1st to compare postoperative outcomes, particularly pain intensity and opioid consumption, between the supine muscle-sparing anterolateral and direct lateral THA approaches. Further research should investigate the effect of surgical approach on quality and cost of care, include larger sample sizes, and involve longer-term follow-up.

Fixator-assisted nailing of tibial fractures: New surgical technique and presentation of first 30 cases.

BACKGROUND: Intramedullary nailing is considered a "gold standard" for treatment of tibial shaft fractures. However, some types of fractures are typically considered as "difficult for nailing". This group includes the periarticular fractures, fractures of both bones at the same level, comminuted and segmental fractures of the tibia. Fixator-assisted nailing (FAN) is an effective method treatment of these types of fractures. The main requirements for the ideal reduction device are an ease of its installation and an ability of multiplanar fracture reduction. Fixator-assisted nailing (FAN) with the use of two perpendicular to each other monolateral tubular frames perfectly meets these requirements. In this study we present this new surgical technique and the analysis of first 30 cases. METHODS: A prospective analysis was conducted for 30 patients with "difficult for nailing" tibial fractures treated with fixator-assisted nailing in our institution between September 1st, 2017, and March 1st, 2018. The duration of surgery and its different stages, the time of fluoroscopy, difficulties encountered during surgery, were analyzed. Clinical and radiological methods were used to evaluated reduction quality. RESULTS: In all 30 cases the acceptable reduction was achieved. The mean duration of the surgical procedure was 73.7 ± 3 min. The mean duration of fluoroscopy 85.9 ± 4.8 s. In 7 cases we faced with technical difficulties, which were successfully addressed. CONCLUSION: The described technique of FAN is an effective method for the treatment of "difficult for nailing" tibial fractures. Future multi-centered studies with a larger number of patients are needed to validate our results.
