Comparison of calcaneus joint internal and external fractures in open surgery and minimal invasive methods in patients

Translational mobility medicine and ugo carraro: a life of significant scientific contributions reviewed in celebration

Prof. Ugo Carraro reached 80 years of age on 23 February 2023, and we wish to celebrate him and his work by reviewing his lifetime of scientific achievements in Translational Myology. Currently, he is a Senior Scholar with the University of Padova, Italy, where, as a tenured faculty member, he founded the Interdepartmental Research Center of Myology. Prof. Carraro, a pioneer in skeletal muscle research, is a world-class expert in structural and molecular investigations of skeletal muscle biology, physiology, pathology, and care. An authority in bidimensional gel electrophoresis for myosin light chains, he was the first to separate mammalian muscle myosin heavy chain isoforms by SDS-gel electrophoresis. He has demonstrated that long-term denervated muscle can survive denervation by myofiber regeneration, and shown that an athletic lifestyle has beneficial impacts on muscle reinnervation. He has utilized his expertise in translational myology to develop and validate rehabilitative treatments for denervated and ageing skeletal muscle. He has authored more than 160 PubMed listed papers and numerous scholarly books, including his recent autobiography. Prof. Carraro founded and serves as Editor-in-Chief of the European Journal of Translational Myology and Mobility Medicine. He has organized more than 40 Padua Muscle Days Meetings and continues this, encouraging students and young scientists to participate. As he dreams endlessly, he is currently validating non-invasive analyses on saliva, a promising approach that will allow increased frequency sampling to analyze systemic factors during the transient effects of training and rehabilitation by his proposed Full-Body in- Bed Gym for bed-ridden elderly.

Arthroscopic Management of Giant Cell Tumor of the Calcaneus

Giant cell tumor of the calcaneal bone is a very rare entity and generally seen in the 30 to 40 years age group. We report a case of a 17-year-old male with giant cell tumor of the calcaneus, presented with left heel pain without another obvious physical abnormality. Radiographs showed a lobulated, well-defined, lytic lesion of the calcaneus with narrow transitional zone without periosteal reaction, no extraosseal spread, and no lung metastases. Arthroscopic procedure was done directly for both diagnostic and curative procedures. All soft, grayish lesions were completely removed arthroscopically using direct lateral portals and the suspected reactive zones debrided using high-speed burr and injected with corticosteroid. Histopathology confirmed the suspected diagnosis. The postoperative clinical course was uneventful with immediate pain relief and full weight bearing and movement allowed soon. The patient had no recurrent pain as well as recurrent radiographic lesions, and normal joint mobility 9 months postoperatively. Considering the accessibility of the lesion, giant cell tumor of the calcaneal bone can be successfully treated arthroscopically using direct lateral approach.Levels of Evidence: Therapeutic, Level IV: Retrospective, case report.

Reduced pre-operative skin oxygen saturation predicts revision after open reduction and internal fixation in calcaneal fractures : A reduced pre-operative oxygen saturation as measured by laser-Doppler spectrophotometry in 8 mm depth is associated with revision surgery after open reduction and internal fixation of calcaneal fractures through an extended lateral approach

PURPOSE

To assess which pre-operative parameters correlate with wound revisions after an extended lateral approach to the calcaneus.

METHODS

Pre-operative laser-Doppler spectrophotometry was applied in patients undergoing open reduction and internal fixation. The number of wound revisions was recorded during pos-toperative follow-up. Spearman rho analysis was used to identify factors associated with wound revision and receiver operator characteristics curves were calculated for the identified factors.

RESULTS

Thirty-four patients (29 men, 5 women; 37 calcanei) with a mean patient age of 43 ± 14 years were analyzed. The minimal oxygen saturation value at the five measurement locations as well as the minimal value for flow correlated negatively with wound revisions (p value = 0.025 and 0.038, respectively). The area under the curve for the pre-operative minimal value of oxygen saturation was 0.841 (95%CI 0.64-1.00, p = 0.028), indicating a good accuracy as a test to predict wound revision.

CONCLUSION

A pre-operative oxygen saturation of at least 20.5% across five measurement points along the anticipated incision identified all patients not needing a wound revision (negative predictive value 100%). On the other hand, patients with at least one measurement below 20.5% were at risk for wound revision surgery (sensitivity 100%, specificity 48.5%). ClinicalTrials.gov NCT01264146.

Sinus Tarsi Approach with Subcutaneously Delivered Plate Fixation for Displaced Intra-Articular Calcaneal Fractures

Displaced intra-articular calcaneal fractures can be treated with open reduction and internal fixation through various methods, including the extensile lateral approach, sinus tarsi approach, percutaneous reduction and fixation, external fixation, and calcaneoplasty. Although the gold standard is the extensile lateral approach, this method has significant wound-healing complications associated with it. Literature shows that the reduction achieved through minimally invasive techniques is equal to that achieved with the extensile lateral approach, while reducing the amount of postoperative complications. This article outlines a technique that uses the sinus tarsi approach with subcutaneous plate fixation.

EJTM3 is also covering Mobility and Medicine at large, an update

Since the first 2018 issue, the European Journal of Translational Myology expanded its authorship and readership from the strict topics of biology, physiology, diagnostic, management and rehabilitation of skeletal muscle to the more clinically relevant fields of human mobility to those of general medicine. This third issue opens with a review on Chronic Fatigue Syndrome, a very complex medical problem, as its other names testify (Myalgic Encephalomyelitis or Systemic Exertion Intolerance Disease). A more typical molecular myology original article follows (Increasing autophagy does not affect neurogenic muscle atrophy), but then several Rapid Reports cover different Medical Specialties fields, related or unrelated to neuromyology, mobility problems and their potential solutions. The Advisors of EJTM invite Authors to submit typescripts, taking into account that the journal is keen to publish high-level papers in the fields of Translational Myology, Mobility and Medicine at large.

Implementing EjtM3 (European Journal of Translational Myology, Mobility, Medicine) along the silk-road

Two main novelties will appear in the second 2018 Issue of the European Journal of Translational Myology demonstrating that the journal is vital and in expansion, one novelty is that the journal is implementing its authorship and readership to broader clinical fields from muscle myology and mobility to clinical medicine and surgery. Consequently, the Editorial Board is also expanding to allow a broader expert evaluation of Authors submitted typescripts. The expanded Editorial Board recently evaluated the option to change the name of the journal from Ejtm to EjtM3 (Myology, Mobility, Medicine), in order to expand the original journal title meaning. Another important novelty is the first BAM Seminal Paper by Damraurer et al. 18(5): 139-148, 2008. It is now reprinted (with Basic and Applied Myology permission) in this Ejtm 28(2), 2018. The topic (chemotherapy-induced muscle wasting) was up-dated by one of our Editors stressing the relevance of the BAM 2008 paper to focus attention not only of myologists, but also of oncologists. From 2008, BAM (renamed from 2010 European Journal of Translational Myology) went far beyond the limits of pure Myology. Al last, but hopefully not at least, a series of Rapid Reports from Iranian Authors are paving the pathway Venetia-extreme Orient, along the ancient silk-road. Ejtm will enthusiastically publish clinical activities from surrounding and extreme Orient. The Marco Polo tradition and his bravery seem successfully continuing.
