INTRODUCTION: It is hypothesized that systemically administered antibiotics penetrate wound sites more effectively during negative pressure wound therapy (NPWT). However, there is a lack of clinical data from patients who receive NPWT for deep sternal wound infection (DSWI) after open-heart surgery. Here, we evaluated vancomycin penetration into exudate in this patient group. PATIENTS AND METHODS: For this prospective observational study, we enrolled 10 consecutive patients treated with NPWT for post-sternotomy DSWI. On the first sampling day, serum and exudate samples were synchronously collected at 0 (pre-dose), 0.5, 1, 2, 3 and 6 h after vancomycin administration. On the following three consecutive days, additional samples were collected, only before vancomycin administration. RESULTS: The ratio of average vancomycin concentration in wound exudate to in serum was higher for free (unbound) (1.51 ± 0.53) than for total (bound + unbound) (0.91 ± 0.29) concentration (p = 0.049). The percentage of free vancomycin was higher in wound exudate than serum (0.79 ± 0.19 vs. 0.46 ± 0.16; p = 0.04). Good vancomycin wound penetration was maintained on the following three days (vancomycin trough exudate-to-serum concentration ratio > 1). The total hospital stay was significantly longer in patients with DSWI (46 ± 11.6 days) versus without DSWI (14 ± 11.7 days) (p < 0.001). There was no in-hospital or 90-day mortality. Two patients experienced late DSWI recurrence. All-cause mortality was 4.8% during a median follow-up of 2.5 years. CONCLUSION: Vancomycin effectively penetrates wound exudate in patients receiving NPWT for DSWI after open-heart surgery.The protocol for this study was registered at ClinicalTrials.gov on July 16, 2024 (NCT06506032).

The pertinent literature widely describes ultrasound-guided procedures targeting the retrocalcaneal bursa and the tendon tissue to manage insertional Achilles tendinopathy. Synovial bursae and cutaneous nerves of the superficial retrocalcaneal pad are often overlooked pain generators and are poorly considered by clinicians and surgeons. A layer-by-layer dissection of the superficial soft tissues in the retrocalcaneal region of two fresh frozen cadavers was matched with historical anatomical tables of the textbook Traite d'Anatomie Topographique Avec Applications Médico-Chirurgicales (1909 by Testut and Jacob). An accurate and detailed description of the superficial retrocalcaneal pad with its synovial bursae and cutaneous nerves was provided. Cadaveric dissections confirmed the compartmentalized architecture of the superficial retrocalcaneal fat pad and its histological continuum with the superficial lamina of the crural fascia. Superficial synovial tissue islands have been demonstrated on the posterior aspect of the Achilles tendon in one cadaver and on the posterolateral surface of the tendon in the other one. Digitalization of the original anatomical tables of the textbook Traite d'Anatomie Topographique Avec Applications Médico-Chirurgicales (1909 by Testut and Jacob) showed five potential locations of the superficial calcaneal bursa and a superficial retrocalcaneal nerve plexus within the Achilles tendon-fat pad interface. In clinical practice, in addition to the previously described interventions regarding the retrocalcaneal bursa and the tendon tissue, ultrasound-guided procedures targeting the synovial and neural tissues of the superficial retrocalcaneal pad should be considered to optimize the management of insertional Achilles tendinopathy.

Iliac crest is common site for harvesting bone grafts. Morphometry of iliac crest is of vital importance in orthopedic surgery. Measurements were done on male (n=85) and female (n=85) hip bones. Length of iliac crest, thickness of iliac crest and ilium were measured. Thickness was measured at pre-defined points on crest and ilium 2 cm apart starting from anterior superior iliac spine (ASIS). Ilium was measured at a depth of 2.5 cm from crest. Statistical analysis was done. Iliac crests were longer in male bones. Ventral iliac crest was thickest at 6 cm from ASIS in both sexes. While iliac crest bore minimum thickness at 12 cm and 10 cm from ASIS in male and female bones respectively, however at 2.5 cm below iliac crest surface ilium was thickest at 4 cm from ASIS and at ASIS in male and female bones respectively. In case of male bones, dorsal part of iliac crest was thickest at 2.15 ± 1.29 cm from posterior superior iliac spine (PSIS) while in females it was at 1.78 ± 1.31 cm from PSIS. In dorsal part of ilium, it was observed at 2.31 ± 1.47 cm and 1.9 ± 1.79 cm from PSIS for male and female bones respectively. This study provided detailed variable morphometry and significant sexual dimorphism observed in iliac crest and ilium. Thickest safe zones in both sexes are a useful guide for harvesting appropriate bone grafts.

BACKGROUND: Spinal cord injury results in permanent neurological impairment and disability due to the absence of spontaneous regeneration. NG101, a recombinant human antibody, neutralises the neurite growth-inhibiting protein Nogo-A, promoting neural repair and motor recovery in animal models of spinal cord injury. We aimed to evaluate the efficacy of intrathecal NG101 on recovery in patients with acute cervical traumatic spinal cord injury. METHODS: This randomised, double-blind, placebo-controlled phase 2b clinical trial was done at 13 hospitals in the Czech Republic, Germany, Spain, and Switzerland. Patients aged 18-70 years with acute, complete or incomplete cervical spinal cord injury (neurological level of injury C1-C8) within 4-28 days of injury were eligible for inclusion. Participants were initially randomly assigned 1:1 to intrathecal treatment with 45 mg NG101 or placebo (phosphate-buffered saline); 18 months into the study, the ratio was adjusted to 3:1 to achieve a final distribution of 2:1 to improve enrolment and drug exposure. Randomisation was done using a centralised, computer-based randomisation system and was stratified according to nine distinct outcome categories with a validated upper extremity motor score (UEMS) prediction model based on clinical parameters at screening. Six intrathecal injections were administered every 5 days over 4 weeks, starting within 28 days of injury. Investigators, study personnel, and study participants were masked to treatment allocation. The primary outcome was change in UEMS at 6 months, analysed alongside safety in the full analysis set. The completed trial was registered at ClinicalTrials.gov, NCT03935321. FINDINGS: From May 20, 2019, to July 20, 2022, 463 patients with acute traumatic cervical spinal cord injury were screened, 334 were deemed ineligible and excluded, and 129 were randomly assigned to an intervention (80 patients in the NG101 group and 49 in the placebo group). The full analysis set comprised 78 patients from the NG101 group and 48 patients from the placebo group. 107 (85%) patients were male and 19 (15%) patients were female, with a median age of 51·5 years (IQR 30·0-60·0). Across all patients, the primary endpoint showed no significant difference between groups (with UEMS change at 6 months 1·37 [95% CI -1·44 to 4·18]; placebo group mean 19·20 [SD 11·78] at baseline and 30·91 [SD 15·49] at day 168; NG101 group mean 18·23 [SD 15·14] at baseline and 31·31 [19·54] at day 168). Treatment-related adverse events were similar between groups (nine in the NG101 group and six in the placebo group). 25 severe adverse events were reported: 18 in 11 (14%) patients in the NG101 group and seven in six (13%) patients in the placebo group. Although no treatment-related fatalities were reported in the NG101 group, one fatality not related to treatment occurred in the placebo group. Infections were the most common adverse event affecting 44 (92%) patients in the placebo group and 65 (83%) patients in the NG101 group. INTERPRETATION: NG101 did not improve UEMS in patients with acute spinal cord injury. Post-hoc subgroup analyses assessing UEMS and Spinal Cord Independence Measure of self-care in patients with motor-incomplete injury indicated potential beneficial effects that require investigation in future studies.

Synovial fluid (SF)-derived monocyte-macrophage (MON-Mφ)-lineage cells in knee osteoarthritis (KOA) remain poorly understood. We analyzed SF samples from 420 patients with KOA with effusion. The MON-Mφ cells accounted for 47.4% (median; range 7.1%-94.4%) of CD45+ cells and consisted of four subpopulations that correlated with the distribution and activation of other immune cells. The most abundant subpopulation was that of inactive CD11b+CD14-CD16- myeloid dendritic cells (mDCs; cDC2), which exhibited low cytokine production, low T lymphocyte stimulation, and high migratory ability. Other major subpopulations included CD11b+CD14+CD16- monocyte-like cells and CD11b+CD14+CD16+ macrophages, which share a similar transcriptomic profile. A subpopulation of CD11b-CD14-CD16- mDCs (cDC1) was less common. A higher proportion of CD11b+CD14-CD16- mDCs was linked to early-stage KOA and mild joint pain. Dendritic cells were rarely present in KOA synovium. This study revealed the considerable complexity of SF-derived MON-Mφ subpopulations and highlighted the role of inactive mDCs in KOA.

PURPOSE OF THE STUDY: Os vesalianum pedis (OVP) is a rare accessory bone of the foot located at the base of the fifth metatarsal bone. It is usually asymptomatic and incidentally seen on radiographs. When symptomatic, it manifests itself with lateral foot pain. OVP, which can become symptomatic as a result of traumatic injuries, can also be confused with fracture. The aim of this study is to determine the prevalence and morphometric characteristics of OVP in the Turkish population. MATERIAL AND METHODS: Radiographic images of 5268 individuals aged 16 years and older (mean 39.65±17.21) who completed ossification of the fifth metatarsal bone were evaluated for OVP. Of the cases included in the study, 44.8% were female and 55.2% were male. The general and sex-based prevalence of OVP was calculated, and morphometric measurements were done. RESULTS: OVP prevalence in the Turkish population was found to be 0.15% regardless of sex. OVP prevalence was calculated to be 0.24% in men and 0.04% in women. CONCLUSIONS: Anatomy, radiology, orthopedics and emergency medicine physicians are frequently encountered with foot disorders in clinical and educational practices. It is important to keep in mind the rare presence of OVP (0.15%), in the preliminary diagnosis. KEY WORDS: os vesalianum pedis, accessory ossicle, foot, radiography.

PURPOSE OF THE STUDY: Osteoarthritis (OA) of the joints of the hand is one of the most common musculoskeletal disorders in the elderly population. It is a complex, degenerative disease affecting all components of the joint. Surgical treatment is indicated when conservative therapy fails. The ultimate solution is arthrodesis of the distal interphalangeal (DIP) joint. Various methods of arthrodesis have been described, ranging from the use of K-wires or compression screw to different types of intra-articular (intramedullary) implants. The aim of this study is to evaluate the surgical outcomes of arthrodesis of the distal interphalangeal (DIP) joint of the fingers using intramedullary implants. MATERIAL AND METHODS: Since 2011, arthrodesis of the distal interphalangeal joint using an intramedullary implant has been performed at our department 97 times in total, in 59 patients. 9 patients (15 cases of arthrodesis) were excluded from the study group due to their failure to complete the questionnaire, 1 female patient died. In the final group, 82 cases of arthrodesis in 49 patients (47 women, 2 men) were evaluated. In 72% of cases, the surgery was performed on the dominant hand. The mean age at the time of surgery was 58 years (median 59 years). The patients were indicated for surgery after the failure of all conservative treatment options. In addition to radiographs, also the hand function and pain were assessed based on the preand postoperative DASH score questionnaires. RESULTS: The surgical outcomes for all implants are satisfactory. In all 82 patients, the surgical wounds healed per primam. In one case, implant extraction was performed due to infection. Another complication was an unhealed fusion and formation of a non-union with minimum pathological mobility (the patient is satisfied with the outcome). In three patients, a fracture at the base of the distal phalanx was observed on postoperative radiographs, which fully healed within 3 months after surgery. The mean DASH score decreased from 41.95 preoperatively to 14.93 postoperatively. The mean time to healing of the arthrodesis observed on radiographs was 9.1 weeks. DISCUSSION: Currently, there are many different types of arthrodesis of the distal interphalangeal joint of the hand. Each method has its pros and cons. Arthrodesis using an intramedullary implant has the advantages of the older methods while minimizing postoperative complications. Our results are comparable to those reported in the foreign literature. CONCLUSIONS: Based on the evaluated outcomes, arthrodesis of the distal interphalangeal joint using an intramedullary implant can be considered valid. It definitely deserves to be included in the portfolio of surgical treatment of osteoarthritis of the DIP joints of the hand. According to our observation, the differences between various types of implants are minimal and their outcomes are comparable to those reported in foreign publications. The pain relief, restored finger function and fusion rate are comparable to, if not better than, those achieved by the older surgical methods. The advantage of this method is mainly easier implantation, fewer complications, and the possibility of implantation without the use of an X-ray image intensifier, which ultimately reduces the cost of surgery. The main disadvantage is the higher purchase price of the implant. KEY WORDS: osteoarthritis, distal interphalangeal joint, arthrodesis.

The bone transport technique uses the principle of distraction-osteogenesis and fill bone defects with the aid of an external fixator. In order to evaluate the clinical effect of femoral internal fixation with Ortho-Bridge System after bone transport, 4 patients after femoral bone transport from October 2020 to October 2022 are studied in this paper. Among them, 3 patients ran refracture of femur after removal of the Limb reconstruction system, 1 patient just finish femoral bone transport and request internal fixation. The surgery results show that Ortho-Bridge System can be used in the situation that conventional Locking compression plate and intramedullary nail are not suitable due to anatomical variation after femoral bone transport. Key words: femoral fracture; Ortho-Bridge System; bone transport; postoperative complications of bone transport.

Significant malrotation of the femur after osteosynthesis is a serious complication of treatment and has a number of consequences for the patients and causes deterioration of their quality of life. Therefore, it is necessary to be familiar with intraoperative techniques to control the correct rotation, mostly clinical and radiological, which give us the possibility to minimize rotational errors. In the postoperative period, with even a slight suspicion of malrotation, it is necessary to proceed to its exact verification and, in indicated cases, to perform necessary correction. We recommend one of the CT techniques as a very reliable method, however in younger patients we prefer to use MRI. Early diagnosis of the rotational error and especially its size is essential from the point of view of potential reconstructive surgery, which is then chosen also with regard to the location of the original lesion. Key words: femoral osteosynthesis, limb malrotation, methods of measuring.

Background: Femoroacetabular impingement syndrome (FAI) is a complex, often post-traumatically developing impairment of the hip joint. It is characterized by ambiguous symptomatology, which makes early diagnosis difficult. Aim: The study was conducted to evaluate the applicability of a triaxial gyroscopic sensor in routine practice as an additional indication criterion for operative versus conservative treatment procedures. Methods: Ninety-two patients were included in the experimental retrospective study and 62 completed the examination. All patients signed informed consent. A gyroscopic sensor was placed on the right side of the pelvis above the hip joint and patients walked approximately 15 steps. Data were also evaluated while the patients climbed stairs. A complete clinical examination of the dynamics and physiological movements in the joint was performed. The data measured by the gyroscopic sensor were processed using differential geometry methods and subsequently evaluated using spectral analysis and neural networks. Results: FAI diagnosis using gyroscopic measurement is fast and easy to implement. Our approach to processing the gyroscopic signals used to detect the stage of osteoarthritis and post-traumatic FAI could lead to more accurate detection and capture early in FAI development. Conclusions: The obtained data are easily evaluated, interpretable, and beneficial in the diagnosis of the early stages of FAI. The results of the study show that this approach can lead to more accurate and early detection of osteoarthritis and post-traumatic FAI.
