The development of musculoskeletal radiology for 100 years as presented in the pages of Acta Radiologica.

During the last 100 years, musculoskeletal radiology has developed from bone-only radiography performed by everyone to a dedicated subspecialty, still secure in its origins in radiography but having expanded into all modalities of imaging. Like other subspecialties in radiology, it has become heavily dependent on cross-sectional and functional imaging, and musculoskeletal interventions play an important role in tumor diagnosis and treatment and in joint diseases. All these developments are reflected in the pages in Acta Radiologica, as shown in this review.

The history of bone marrow in orthopaedic surgery (part I trauma): trepanning, bone marrow injection in damage control resuscitation, and bone marrow aspiration to heal fractures.

PURPOSE: One of the oldest procedures performed by man is trepanning of the bone and yet it was only in the last 40 years that bone marrow aspiration has been used to treat nonunion disorders. MATERIAL AND METHODS: These advances were possible due to improvements in instruments and in techniques to make holes in the bone, an history that began with skull trephinations around 8000-10,000 years ago, and continued with sternum bone marrow injection for trauma resuscitation in the beginning of the twentieth century; this procedure had improved at the beginning of the twenty-first century to allow pelvis bone marrow aspiration for the treatment of nonunion. RESULTS: Trephined skulls from antiquity have been found in many parts of world, showing that trephining was ancient and widespread. Beginning with Neolithic period and the pre-Columbian Andean civilizations, the authors have traced the development of this surgical skill by describing the various surgical tools used to perform holes in the skull. These tools (trephines or trepan) were proposed at the end of the nineteenth century to study the bone marrow. At the beginning of the twentieth century, the sternum became the center of interest for the "in vivo" study of the bone marrow and the fluid injection in the sternum's bone marrow was described for resuscitation from shock during the World War II. With the introduction of plastic catheters and improved cannulation techniques, the need for intraosseous infusion as an alternative route for intravenous access diminished and sometimes abandoned. However, during the mid-1980s, James Orlowski allowed renaissance of the use of intraosseous infusion for paediatric resuscitation. Since then, this technique has become widespread and is now recognized as an alternative to intravenous access in adult emergencies; particularly, the intraosseous access has received class IIA recommendation from the Advanced Trauma Life Support program supported by the American College of Surgeons Committee on Trauma and bone marrow infusion is now recommended for "Damage Control" resuscitation. Although the pelvis bone contains half of the body's marrow volume, it was only in 1950 that the pelvis was proposed as a source for bone marrow aspiration and bone marrow-derived mesenchymal stem cells to improve healing of fractures. CONCLUSION: It will be many years before doing holes in the bone as orthopaedic trauma procedure will be relegated to the annals of history.

Ideal xenograft or a perfect bone substitute?-A retrospective review and analysis of the historical concept of ivory implants in orthopaedics.

PURPOSE: Surgical treatment of fractures has evolved with the development of anaesthesia in 1846. Experiments with different implants both organic and non-organic had led to introduction of sometimes extremely peculiar materials coming from different species like ox bone or elephant's ivory. The aim of this article is to present not widely known concept of ivory use in bone surgery that set its foot in the history of orthopaedics and laid foundations for orthobiologic reconstructions. METHODS: Retrospective analysis of articles and books published between 1846 and 2017 that describe various examples of ivory application in the treatment of fresh fractures, non-unions and reconstruction of joints. RESULTS: Our research shows that ivory to the surgical world was introduced by Friedrich Dieffenbach, founder of the modern plastic surgery. It was also used with different rate of success by many of the famous surgeons of the nineteenth and twentieth century to include Trendelenburg, Billroth, Volkmann, Paget and Hey Groves. Ivory was immensely popular in bone surgery and became material of choice demonstrating amazing biological properties and very low rate of infections. CONCLUSION: Ivory has served well in successful treatment of various orthopaedic conditions for over 100 years. In this article, we are using history as a stepping stone to examine material that is not rejected by the body and promotes bony healing without increased infection or other complications. It is worth considering further analysis of historically acquired specimens for further development of materials for further orthopaedic fracture and reconstructive techniques.

Girolamo Fabrici d'Acquapendente and the Oplomochlion: The Several Applications of an Effective Rehabilitation Tool.

Girolamo Fabrici d'Acquapendente (1533-1619) was an Italian anatomist, surgeon and physiologist and a protagonist of the scientific revolution of the Renaissance. He made anatomy a scientific discipline and is justly considered a precursor of modern orthopaedics. He invented and used several external corrective devices for the treatment of congenital and acquired deformities of the limbs and spinal column, especially those following tubercular infection and rickets, torticollis, vertebral caries kyphosis, scoliosis, and rachitic deformities of the leg, but also congenital dislocation of the hip and congenital club-foot. He ascribed the pathogenesis of the equinovarus supinated foot to the position taken by the foot of the fetus during intrauterine life. The Oplomochlion, shown in the Operationes chirurgicae and attributed to Fabrici, is actually a collection of very diverse orthotic, prosthetic and surgical metal instruments invented by Fabrici and arranged with a demonstrative purpose and a topographic criterion, as if on an exhibition dummy.

The Iron Man of the Renaissance: the contribution of Girolamo Fabrizi d'Acquapendente.

PURPOSE: To highlight the most relevant contributions of the Italian Renaissance surgeon Girolamo Fabrizi d'Acquapendente in the field of orthopaedics and traumatology. METHODS: An extensive research on the life and achievements of Girolamo Fabrizi was conducted on University Libraries as well as on electronic databases like PubMed. RESULTS: Girolamo Fabrizi d'Acquapendente is known for his embryology and physiology studies, particularly on sensory organs and blood circulation. He founded the world's first permanent anatomical theater established at the University of Padua and inaugurated in 1595. His most notable publications include surgical and definitely orthopedics works such as "De fracturis" (On fractures) and "De luxationibus" (On joint displacement). He outlined some principles of treatment that are still valid nowadays such as anatomical reduction and stabilization of the fracture, that were applied using the equipment available at that time. He described and illustrated maneuvers and instruments, such as pulleys, winches, splint, and bandages. He further depicted the famous "Oplomochlion" ("the armored man"), which is actually a collection of all of the braces used at the time to correct congenital and post-traumatic deformities. CONCLUSION: Bracing and prosthetic replacements have accompanied medical history throughout the centuries, from Ancient Egypt to the present, but it was the ingenuity of Renaissance surgeons that pushed biomedical technology to new heights: Girolamo Fabrizi d'Acquapendente was one of the most illustrious contributors to these great achievements.

Abulcasis (936-1013): his work and contribution to orthopaedics.

AIM OF THE STUDY: The purpose of this historic review is to summarize the life and work of Abulcasis (936-1013) and his contribution to surgery and orthopaedics. METHOD: We conducted an extensive search in libraries as well as online in PubMed and Google Scholar. RESULTS: Abulcasis in his work combines the knowledge of ancient Greek and Roman physicians and surgeons with the extensive knowledge of Arabic medicine and pharmacology. He also pioneered surgical technique with the invention of numerous surgical instruments and with several revolutionary surgical techniques. CONCLUSION: Abulcasis made an impact with his medical writings in which he summarized the works of ancient Greek and Roman physicians like Hippocrates and Galen with the influence of medieval authors and the knowledge of the Arabic medicine and pharmacology. His descriptions and innovations in his work remained a work of reference in the West and East for many centuries to come.

State of the art forensic techniques reveal evidence of interpersonal violence ca. 30,000 years ago.

The Cioclovina (Romania) calvaria, dated to ca. 33 cal ka BP and thought to be associated with the Aurignacian lithic industry, is one of the few relatively well preserved representatives of the earliest modern Europeans. Two large fractures on this specimen have been described as taphonomic modifications. Here we used gross and virtual forensic criteria and experimental simulations on synthetic bone models, to investigate their nature. Both forensic trauma pattern analysis and experimental models exclude a postmortem origin for the Cioclovina fractures. Rather, they indicate two incidents of blunt force trauma, the second clearly inflicted with a club-like object. The magnitude and extent of the lesions and the lack of signs of healing indicate a fatal injury. The Upper Paleolithic period is noted for intensified technological innovation, increased symbolic behavior, and cultural complexity. We show that the behavioural repertoire of the earliest modern Europeans also comprised violent inter-personal interactions and murder.

A GIS based approach to long bone breakage patterns derived from marrow extraction.

In archaeological assemblages the presence of percussion marks, on the surface of long bones, is an indicator of long bone marrow extraction. The form, quantity and distribution of percussion marks are analysed to gain a better understanding of the marrow extraction process. Patterns of bone percussion damage in archaeological assemblages may highlight standardized actions, possibly related to butchery traditions. However, additional factors could underlie these patterns and should also be considered. In this article we test intuitiveness as a factor in appearance of percussion mark patterns, to see if patterns can appear when bones are being fractured without prior experience with bone fracture properties. To test this hypothesis, for this study we selected a sample of 40 cattle (Bos taurus) long limb bones from a large bone breakage experiment (400 long limb bones), where participants had no previous experience in bone breakage and may thus have broken bones intuitively. We used Geographic Information System (GIS) software to analyse the distribution of percussion marks. Using ArcGIS Spatial Analysts tools, we identified and quantified significant concentrations of percussion marks. Results show that percussion mark patterns emerge for the same bone element, and that specific sides and zones were recurrently selected by experimenters. The distribution of patterns varies among the different long bone elements, and we attribute this variance to an adjustment to bone morphology. In addition, we calculated and identified bone damage patterns resulting from hammerstone percussion. Crossing bone survivorship with percussion mark patterns enabled us to recognise and evaluate the effects of fragmentation and surface visibility in controlled experimental conditions. The GIS method facilitates comparisons between different variables and provides a sophisticated visual representation of results. Enlarging the sample will allow to constitute a more substantial analogous model for fossil assemblages.

Evidence of infectious disease, trauma, disability and deficiency in skeletons from the 19th/20th century correctional facility and asylum «Realta¼ in Cazis, Switzerland.

As a reaction to widespread poverty, a system of coercive welfare developed in Switzerland during the 19th century. Poverty was often thought to result from an individual's misconduct rather than from structural, economic or political circumstances. People whose lifestyle deviated from the desired norm or who were unable to make a living for themselves were subjected to so-called administrative detention at institutions such as workhouses and poorhouses. The excavation of the cemetery of the correctional facility/workhouse and asylum «Realta¼ in Cazis offered the opportunity to gain insight into the living conditions of a marginalized group of people and to shed light on aspects of coercive welfare that have hardly been addressed in historical studies. A comprehensive study of pathological alterations was used to assess possible physical causes and effects of administrative detention. Skeletal samples from regular contemporaneous cemeteries provided data for the general population and thus allowed us to detect peculiarities in the «Realta¼ assemblage. Possible cases of Stickler Syndrome, microcephaly, congenital syphilis, endemic hypothyroidism and disabilities secondary to trauma may have been the reason for the affected individuals' institutionalisation. The high prevalence of tuberculosis was linked to the socioeconomic status and the living conditions at the facility. Several cases of scurvy and osteomalacia may have resulted from various risk factors such as poverty, alcoholism, mental illness or institutionalisation. The fracture rates, especially of ribs, were extremely high. A large proportion of the fractures were incompletely healed and most likely occurred during detention due to interpersonal violence. Underlying diseases further contributed to the high fracture rates. This first study on skeletons from an institution of administrative detention in Switzerland demonstrated how pre-existing health conditions and the socioeconomic background contributed to the chance of being detained, and how detention led to further deterioration of health.

The influence of war on population-based fracture distribution patterns: An example from medieval England.

Elevated levels of non-accidental fractures in different populations, regions, and time periods are considered an indicator for violence within a population. Whilst soldiers from a mass grave contribute unambiguously to the bioarchaeological evidence for the presence of warfare in medieval England, we aim to further analyse the absence of temporal variation in the general population-wide fracture distribution pattern. A detailed study, consisting only of clearly dated and aged male individuals was conducted to investigate the impact of prolonged warfare and general instability by means of blunt force fracture distribution patterns in early (AD 1066-1100), middle (AD 1100-1380) and late (AD 1380-1558) medieval England. Statistically significant differences were only observed between the 26-35 years age group of the middle period (AD 1100-1380) vs the 18-25 year age group of the late period (AD 1380-1558). The latter included many individuals from Towton, North Yorkshire, and therefore battle-related injuries are reflected in the pattern. The former presented inconclusive causal effects, none of them could be reliably linked to warfare. It was concluded that aside from the inclusion of battle-related graves no evidence for the impact of prolonged warfare and economic instability could be observed in medieval England.

Descriptive Epidemiology of New Zealand's Highest Mortality Earthquake: Hawke's Bay in 1931.

In this study we aimed to produce the first detailed analysis of the epidemiology of the severe injury and mortality impacts of the 1931 Hawke's Bay earthquake in New Zealand (NZ). This involved the compilation and analysis of archival data (hospitalisations and deaths) including the examination of 324 death certificates. We found that there were 662 people for whom some hospitalisation data were available at four weeks post-earthquake: 54% were still in hospital, 4% were still classified as "serious", and 5% had died (n = 28). Our classification of death certificate data indicated 256 earthquake-attributable deaths and for another five deaths the earthquake was estimated to have played an indirect role. There were 15 buildings associated with three or more deaths each (accounting for 58% of deaths with a known location). Many of these buildings were multi-storey and involved unreinforced masonry - with some of this falling into the street and killing people there (19% of deaths). In contrast, deaths in homes, which were typically of wood construction and single stories, comprised only 3% of deaths. In conclusion, this earthquake had a relatively high injury impact that appears partly related to the lack of regulations for building construction that would mitigate earthquake-related risk. Such regulations continue to be of relevance for New Zealand and for other countries in earthquake zones.

Revisiting traumatic injury risk and agricultural intensification: Postcranial fracture frequency at Cerro Oreja in the Moche Valley of north coastal Peru.

OBJECTIVES: In Lambert and Welker (2017) we explored the association between subsistence economy and postcranial fracture prevalence, finding that low-intensity agriculturalists exhibited significantly lower fracture rates than foragers or high-intensity agriculturalists. Here, we explore the impacts of sampling strategy on fracture rates in a sample of high-intensity agriculturalists from the Moche Valley, Peru, and further test the hypothesis that postcranial fracture risks are higher for intensive agriculture. MATERIALS AND METHODS: The long bones and clavicles of 102 individuals from an Early Intermediate Period cemetery (400 B.C.-A.D. 200) at Cerro Oreja were examined for healed fractures. Sample composition was manipulated in six ways to investigate the effects of age and element completeness on estimates of fracture prevalence. Fracture rates at Cerro Oreja were then compared to those for other high-intensity agriculturalists. RESULTS: Both skeletal element completeness and age composition were found to influence fracture rate estimates, reflecting the greater likelihood of identifying healed fractures on better-preserved bones and the accrual of injuries with age. The fracture rate of 3.4% at Cerro Oreja was the median value among seven high-intensity agriculturalist samples. The fracture distribution at Cerro Oreja was most similar to that observed at Kulubnarti, Sudan (Kilgore et al., 1997). DISCUSSION: Skeletal element completeness and age composition can impact fracture rates estimated for skeletal samples and should be considered when conducting comparative analyses. All rates calculated for Cerro Oreja are within the range of those obtained for other high-intensity agriculturalists and support previous findings that traumatic injury risk is higher for high-intensity agriculturalists. Similarities between Cerro Oreja and Kulubnarti suggest that rugged terrain may exacerbate fracture risk for agriculturalists, illustrating the costs of intensive agriculture in suboptimal environments.

Trauma in the upper limb of an Upper Paleolithic female from Caviglione cave (Liguria, Italy): Etiology and after-effects in bone biomechanical properties.

The impact of injury on the health and activities of human foragers is of great interest for understanding the adaptability of past populations to their environments. For the Gravettian female of Caviglione 1, a violent blow has been suggested as the origin of the left radial fracture, and abnormal body asymmetry has been observed. Access to high resolution CT-scans of the upper limb allows us to address new etiologic considerations and assess the after-effects of trauma on bone biomechanical properties by focusing on cortical and trabecular bones and conducting a comparative analysis of cross-sectional geometric properties in an Upper Paleolithic context. This originally right-dominant female, who became left-handed, was mainly affected by severe bone modifications on the proximal right humerus due to secondary changes following a traumatic event. The left radial fracture is very well consolidated with thick and homogeneous cortical bone. Etiological considerations point to a Galeazzi fracture for the left forearm occurring during a fall. The bone structure and robusticity of the left arm probably prove the lack of strong and enduring dependency of this female on her group for the usual cultural tasks despite the strongly limited function of the right arm.

Serious chronic disease of the cervical spine and trauma in a young female from the middle ages (Czech Republic).

The skeletal remains of the young female (20-24 years) from Grave JP/106, discovered in the Southern Suburb of the Breclav - Pohansko Stronghold (Early Middle Ages, 9th century-beginning of the 10th century, present day Czech Republic) display several noteworthy pathologies. The first is deformation of the mandible, which was most probably caused by a fracture of the ramus in combination with a subcondylar fracture. The spine of this young woman also exhibits a probable traumatic injury of the cervical spine in combination with a slowly growing structure situated inside the spinal canal, which caused deformation centered upon C7. The cervical and thoracic spine together with internal surfaces of several ribs exhibit infectious changes of advanced stage, in all likelihood of tuberculous origin, but osteomyelitis cannot be excluded. Histological analysis of the new bone formation in the ribs confirmed infectious origin, as does Micro CT of C5 and C6. Analyses conducted by two different departments with different methods (PCR amplification of 123 bp long section from IS6110 and Next Generation shotgun sequencing) failed to identify DNA of Mycobacterium tuberculosis from the first rib.

Time after time: individuals with multiple fractures and injury recidivists in long eighteenth-century (c. 1666-1837) London.

Investigating injury recidivism and individuals with multiple injuries is an area of growing interest in bioarchaeology. Differentiating between whether an individual sustained multiple injuries, represented by antemortem healed fractures, in one incident or in multiple incidents over the life course, is a major challenge. This research analyzed the skeletal remains of 721 adults (402 males, 319 females) from five post-medieval cemeteries from London, UK, known to include working class individuals for evidence of skeletal trauma - fractures, myositis ossificans, subluxations/dislocations, blunt force trauma, and sharp force trauma. A total of 164 individuals had more than two fractures; males were significantly more likely to have multiple (2+) fractures than females. An investigation of fracture recidivism incorporating a relative timeline of fracture events was possible because 14 individuals (12 males, two females) were identified as injury recidivists, meaning they had a combination of antemortem healed, antemortem healing, and/or perimortem fractures. This paper examines the distribution and relative timing of these fractures, incorporating contemporary clinical as well as social and historical context, noting that the majority of the fractures were likely to be caused by accidental mechanisms.
