    ABSTRACT: The Iliad, composed approximately in the middle of the eighth century bc, constitutes the leading and oldest known example of heroic epic. The Homeric epic presents the conflicts that took place during the last year of the 10-year lasting Trojan War, offering a realistic description of battle wounds. We studied the text of The Iliad in ancient Greek and in the translations in modern Greek and English and searched for all recorded injuries to the pelvis and lower extremities. A total of 16 traumatic injuries of pelvis and lower extremities were described, including 7 fatal wounds, while in 9 cases, the outcome was unknown.The Iliad remains the oldest record of Greek medicine and a unique source of surgical history. To study the vividly reported events is a great experience, particularly for a surgeon.

    ABSTRACT: The debate over whether to preserve the posterior cruciate ligament (PCL) in total knee arthroplasty (TKA), so-called cruciate-retaining (CR), or to substitute for it, so-called posterior stabilized (PS), continues to engage orthopedic surgeons. Although multiple differing design philosophies have come and gone over the past several decades, no consensus has been reached as to which knee is preferable. Several factors account for this. First, no clear benefits or drawbacks are apparent for either type of implant to the extent that either is clearly superior. In addition, multiple confounding factors are present in the comparative evaluation of implant studies (e.g. function, patient satisfaction, implant longevity, complication rates etc.), as well as the influence of tradition in the implant choices of most surgeons, which makes comparison difficult.

    ABSTRACT: Total hip replacement is the treatment of choice for the patient suffering from end-stage hip osteoarthritis. Excellent long-term results have been published. In the presence of deformities due to congenital hip dislocation, total hip replacement is, in most of the cases, a difficult task, since the technique of performing such an operation is demanding and the results could vary. This paper presents our experience and preferred strategies focusing on challenges and surgical techniques associated with reconstructing the dysplastic hip.

    ABSTRACT: Upper extremity trauma and resulting disability is a stressful event and can affect a patient's personality. Several studies have shown that this injury type has serious psychological and/or social consequences. We systematically reviewed the evidence on the consequences of disability after a complex trauma (combination of soft tissue, osseous, vascular, and nerve involvement) of the upper extremity. We tried to find out the potential crucial factors that could determine the final hand function. In addition, we considered the challenges that need to be addressed to eliminate the adverse or negative effects that arise from upper limb trauma. In the literature, there is a growing interest to study changes in patients' quality of life and return to work. Psychological morbidity is an important part of patients' perceived general health. These issues could play an important role in the final functional outcome of the therapy. An early identification and treatment of trauma-related distress in patients may prevent progression of psychological pathology and mitigate negative effects on general health status. It may be important to evaluate the amount of psychological distress when caring for patients with hand injuries.

    ABSTRACT: Background: To investigate the behavior of Arc2f polyethylene (PE) component after a minimum of 15 years post implantation and its possible reasons for failure. Methods: Between January 1988 and March 1995, 557 cementless total hip arthroplasties were performed in 578 patients. A total of 435 patients (450 hips) were followed up for 18.6 years (range 15-22). Results: At 10 years follow-up no cup needed revision surgery. After 15 years of implantation, we observed massive PE wear in 140 cups (31%) with large osteolytic lesions. A revision procedure was performed in all cases. Exchange only of the PE liner was sufficient in 78 cases, whilst in 59 the cup was also revised. PE insert thickness and the type of prosthetic head were found to be related to PE wear. Conclusions: We postulate that the massive failure seen is attributed to the manufacturing of the PE insert. We advocate following all patients that have an implant lasting a decade after implantation for routine monitoring to identify those at risk for accelerated PE wear.

    ABSTRACT: Undoubtedly, major joint arthroplasty is one of the surgical success achievements of the twentieth century. As demand for primary total hip and knee arthroplasty (THA, TKA) is increasing, the burden of revision arthroplasties is projected to swell concomitantly. Surgeons are increasingly using cementless implants in joint revision surgery because of several reports of a high incidence of loosening in cemented fixation.

    ABSTRACT: So far, predictive models with individualized estimates of prognosis for patients with peripheral nerve injuries are lacking. Our group has previously shown the prognostic value of a standardized scoring system by examining the functional outcome after acute, sharp complete laceration and repair of median and/or ulnar nerves at various levels in the forearm. In the present study, we further explore the potential mathematical model in order to devise an effective prognostic scoring system. We retrospectively collected medical record data of 73 cases with a peripheral nerve injury in the upper extremity in order to estimate which patients would return to work, and what time was necessary to return to the pre-injury work. Postoperative assessment followed the protocol described by Rosén and Lundborg. We found that return to pre-injury work can be predicted with high sensitivity (100%) and specificity (95%) using the total numerical score of the Rosén and Lundborg protocol at the third follow-up interval (TS3) as well as the difference between the TS3 and the total score at second follow-up interval (TS2). In addition, the factors age and type of injured nerve (median, ulnar, or combined) can determine the time of return to work based on a mathematical model. This prognostic protocol can be a useful tool to provide information about the functional and social prospects of the patients with these types of injuries. © 2012 Wiley Periodicals, Inc.

    ABSTRACT: Backround This retrospective study was undertaken to determine the incidence of kidney dysfunction (KD) and to identify potential risk factors contributing to development of KD in orthopaedic population following an elective or emergency surgery. Methods A total of 1025 patients were admitted in our institution over a period of one year with various indications. Eight hundred and ninety-three patients (87.1%) had a surgical procedure. There were 42 (52.5%) male and 38 (47.5%) female with a mean age of 72 years (range: 47 to 87 years). We evaluated the following potential risk factors: age, comorbidities, shock, hypotension, heart failure, medications (antibiotics, NSAIDs, opiates), rhabdomyolysis, imaging contrast agents and pre-existing KD. Results The overall incidence of KD was 8.9%. Sixty-eight patients developed acute renal injury (AKI) and 12 patients developed acute on chronic kidney disease (CKD). In sixty-six (82.5%) patients renal function was reversed to initial preoperative status. Perioperative dehydration (p = 0.002), history of diabetes mellitus (p = 0.003), pre-existing KD (p = 0.004), perioperative shock (p = 0.021) and administration of non-steroid anti-inflammatory drugs (NSAIDs) (p = 0.028) or nephrotoxic antibiotics (p = 0.037) were statistically significantly correlated with the development of postoperative KD and failure to gain the preoperative renal function. Conclusion We conclude that every patient with risk factor for postoperative KD should be under closed evaluation and monitoring.

    ABSTRACT: Proximal femoral nail antirotation devices (PFNAs) are considered biomechanically superior to dynamic hip screws for treating unstable peritrochanteric fractures and reportedly have a lower complication rate. The PFNA II was introduced to eliminate lateral cortex impingement encountered with the PFNA. However, it is unclear whether the new design in fact avoids lateral cortex impingement without compromising stability of fixation and fracture healing. We therefore asked whether the PFNA II: (1) eliminates the lateral cortex impingement and fracture displacement experienced with PFNA; and (2) provides stable fracture fixation with a low major complication rate for unstable fractures in European patients. We retrospectively reviewed 108 patients with an unstable peritrochanteric fracture, 58 treated with PFNA and 50 with PFNA II. We compared nail positioning, major and minor complication rates, operative and fluoroscopy time, blood transfused, time to mobilization, hospital stay, fracture union, and Harris hip score. The minimum followup was 12 months (mean, 13 months; range, 12-18 months). In the PFNA II group we encountered no impingement on the lateral cortex and no patients with lateral fragment or loss of reduction at insertion, whereas with the PFNA group, we had 10 and five cases, respectively. Fracture union occurred in all patients treated with PFNA II without mechanical failures. PFNA II cases were associated with a slightly shorter surgical time than PFNA cases (23 minutes versus 27 minutes, respectively). PFNA II avoided lateral cortex impingement experienced with PFNA, providing fast and stable fixation of the unstable peritrochanteric fractures. Level III, retrospective comparative study. See Guidelines for Authors for a complete description of levels of evidence.

    ABSTRACT: Bacteria have been found to grow predominantly in biofilms. The initial stage includes the attachment of bacteria to the substratum. Bacterial growth and division then leads to the colonization of the surrounding area and the formation of the biofilm. The environment in a biofilm is not homogeneous; the bacteria in a multispecies biofilm are not randomly distributed, but rather are organized to best meet their needs. Although there is an initial understanding on the mechanisms of biofilm-associated antimicrobial resistance, this topic is still under investigation. A variety of approaches are being explored to overcome biofilm-associated antimicrobial resistance. A greater understanding of biofilm processes should lead to novel, effective control strategies for biofilm control and a resulting improvement in patient management.

    ABSTRACT: Peripheral nerve injuries are still underestimated. The complexity of assessment of outcome after nerve injury and repair has been described by many authors. Furthermore, the outcome is influenced by several factors that depend on mechanisms in the peripheral as well as the central nervous system. Appropriate formulation of a global accepted postoperative clinical protocol for peripheral nerve repair in the upper extremity remains a subject of debate. The purpose of this review is to detail the current concepts of methods of evaluation after peripheral nerves repair. Finally, we discuss the most crucial factors that determine the final hand function and we consider the challenges that need to be addressed to create a realistic clinical protocol that reflects a prognostic importance.

    ABSTRACT: We report the long-term results of the management of neglected chronically infected total knee replacements with a two-stage re-implantation protocol. In 18 of 34 patients (53%) a resistant organism was isolated. All cases were treated by the same surgical team in a specialist centre and had a mean follow-up of 12.1 years (10 to 14). They were evaluated clinically and radiologically using the Knee Society Score (KSS) and the American Knee Society Roentgenographic scoring system, respectively. One patient died after eight years from an unrelated cause and two were lost to follow-up. Three patients (8.8%) developed a recurrent infection for which further surgery was required. The infection was eradicated successfully in 31 patients (91.1%). There was one case of aseptic loosening after 13 years. We found a significant improvement in the KSS at final follow-up (p < 0.001).

    ABSTRACT: The combination of dorsal dislocation of the navicular from the talus and a comminuted fracture of the calcaneus (transcalcaneal talonavicular dislocation) is an unusual and severe injury. It occurs due to a forced plantarflexion of the talar head through the anterior portion of the calcaneum and is usually associated with a potential for skin and neurovascular compromise. Few cases have been reported in the literature. This article reports an unusual case of an open transcalcaneal talonavicular dislocation associated with the presence of a calcaneal comminuted calcaneal fracture.

    ABSTRACT: A comparison of outcomes based on a scoring system for assessments, described by Rosén and Lundborg, after sharp complete laceration of median and/or ulnar nerves at various levels in the forearm was carried out. There were 66 males (90.4%) and 7 females (9.6%), with a mean age of 31 years (range: 14-62 years). The patients were categorized into three groups according to the type of nerve injury. The median nerve was injured in 25 cases (group M, 34.3%), the ulnar in 27 (group U, 36.9%), and both the nerves in 21 (group MU, 28.8%). The demographic data of the patients and the mechanism of injury were recorded. We also examined the employment status at the time of the injury and we estimated the percentage of patients who returned to their work after trauma. In all cases, a primary epineural repair was performed. Concomitant injuries were repaired in the same setting. The mean period of time between injury and surgery was 5.3 hours (range: 2-120 hours). A rehabilitation protocol and a reeducation program were followed in all cases. The mean follow-up was 3 years (range: 2-6 years), with more distal injuries having a shorter follow-up period. The total score was 2.71 in group M (range: 0.79-2.99) and 2.63 in group U (range: 0.63-3), with no significant differences observed. There was a significant difference between these two groups and group MU (total score 2.03, range: 0.49-2.76, P = 0.02). Up to the last follow-up, 61 patients (83.5%) had returned to their previous work. The Rosén-Lundborg model can be a useful and simple tool for the evaluation of the functional outcome after nerve injury and repair temporally reflecting the processes of regeneration and reinnervation.
