Albert Dereymaeker and Joseph Cyriel Mulier's description of anterior cervical discectomy with fusion in 1955.

Anterior cervical discectomy with fusion (ACDF) is a very well-known and often-performed procedure in the practice of spine surgeons. The earliest descriptions of the technique have always been attributed to Cloward, Smith, and Robinson. However, in the French literature, this procedure was also described by others during the exact same time period (in the 1950s). At a meeting in Paris in 1955, Belgians Albert Dereymaeker and Joseph Cyriel Mulier, a neurosurgeon and an orthopedic surgeon, respectively, described the technique that involved an anterior cervical discectomy and the placement of an iliac crest graft in the intervertebral disc space. In 1956, a summary of their oral presentation was published, and a subsequent paper-an illustrated description of the technique and the details of a larger case series with a 3.5-year follow-up period-followed in 1958. The list of authors who first described ACDF should be completed by adding Dereymaeker's and Mulier's names. They made an important contribution to the practice of spinal surgery that was not generally known because they published in French.

Dorsal Plating of Distal Radius Fractures Historical Context and Appropriate Use.

The management of distal radius fractures has evolved over time from a largely nonoperative paradigm to a more commonly performed operative procedures today. Surgical trends have similarly developed, with dorsal plating falling out of favor due to complications involving extensor tendon pathology as well as due to the ubiquity of the volar plate along with the advent of locking plate technology. However, with the improvement in design of newer generation dorsal plates, this technique should be used in the appropriate clinical situation, including dorsal comminution and angulation with concomitant carpal pathology. Outcome data supports dorsal plating and has been shown to be comparable to that of volar plating, with some unique advantages. As such, the technique of dorsal plating should have a role in surgical management of these injuries.

History of internal fixation (part 1): early developments with wires and plates before World War II.

Though the date at which an orthopaedic implant was first used cannot be ascertained with any certainty, the fixation of bone fracture using an iron wire was reported for the first time in a French manuscript in 1775. The first techniques of operative fracture treatment were developed at the end of the 18th and in the beginning of the 19th centuries. The use of cerclage wires to fix fractures was the most frequent fixation at this time. The French Berenger-Feraud (1832-1900) had written the first book on internal fixation. However internal fixation of fractures could not become a practical method before Lister had ensured the safety of open reduction and internal fixation in the treatment of fractures. Lister is not only the father of asepsis; he also used metal wires to fix even closed fractures. The first internal fixation by means of a plate and screws was described by Carl Hansmann in 1858 in Hamburg. Nevertheless, Arbuthnot Lane (1892) and Albin Lambotte (1905) are considered to be the founders of this method, which was further developed by Sherman in the first part of the 20th century.

World War II, tantalum, and the evolution of modern cranioplasty technique.

Cranioplasty is a unique procedure with a rich history. Since ancient times, a diverse array of materials from coconut shells to gold plates has been used for the repair of cranial defects. More recently, World War II greatly increased the demand for cranioplasty procedures and renewed interest in the search for a suitable synthetic material for cranioprostheses. Experimental evidence revealed that tantalum was biologically inert to acid and oxidative stresses. In fact, the observation that tantalum did not absorb acid resulted in the metal being named after Tantalus, the Greek mythological figure who was condemned to a pool of water in the Underworld that would recede when he tried to take a drink. In clinical use, malleability facilitated a single-stage cosmetic repair of cranial defects. Tantalum became the preferred cranioplasty material for more than 1000 procedures performed during World War II. In fact, its use was rapidly adopted in the civilian population. During World War II and the heyday of tantalum cranioplasty, there was a rapid evolution in prosthesis implantation and fixation techniques significantly shaping how cranioplasties are performed today. Several years after the war, acrylic emerged as the cranioplasty material of choice. It had several clear advantages over its metallic counterparts. Titanium, which was less radiopaque and had a more optimal thermal conductivity profile (less thermally conductive), eventually supplanted tantalum as the most common metallic cranioplasty material. While tantalum cranioplasty was popular for only a decade, it represented a significant breakthrough in synthetic cranioplasty. The experiences of wartime neurosurgeons with tantalum cranioplasty played a pivotal role in the evolution of modern cranioplasty techniques and ultimately led to a heightened understanding of the necessary attributes of an ideal synthetic cranioplasty material. Indeed, the history of tantalum cranioplasty serves as a model for innovative thinking and adaptive technology development.

History of operative treatment of forearm diaphyseal fractures.

Diaphyseal fractures of the forearm have accompanied humanity throughout its history. Nonsurgical techniques dominated the treatment for centuries, and complications including nonunion and malunion were common. The 19th century featured the recognition of distinct injury patterns. With the development of anesthesia and antisepsis, the operative treatment became widespread. In 1878, Heine described fixation of the diaphyseal nonunion of the distal ulna using an intramedullary ivory peg. Parkhill reported on the application of external fixation for forearm fractures in 1897-1898. Hansmann published the case of plate osteosynthesis of an acute fracture of the radius in 1886. In 1913, Schöne published the technique of closed intramedullary fixation of diaphyseal fractures of the forearm using a silver wire. During the first 2 decades of the 20th century, plate osteosynthesis quickly spread across Europe and North America owing to the influence of Lambotte and Lane. After the World War II, plate osteosynthesis became the surgical treatment of choice for forearm diaphyseal fractures.

Rigid plate fixation promotes better bone healing after sternotomy.

Sternotomy is the most common surgically created osteotomy in surgery. Rigid fixation of osteotomies are important for stability and bony union. This review shows the superiority of rigid plate fixation in achieving better bone healing after sternotomy. It also highlights use of plate fixation for mini-sternotomies and rib fractures.

Treatment of patients with cleft lip, alveolus and palate--a short outline of history and current interdisciplinary treatment approaches.

Clefts of lip, alveolus and palate have been known for a long time. First tangible evidence of surgical therapy in terms of cheiloplasty, however, does not date further back than the 4th century after Christ. It was Werner Hagedorn from Magdeburg who laid the foundations of geometrical anatomical surgical lip repair in 1884. The procedures designed by LeMesurier, Tennison, Randall or Millard in the 1950s, and by Pfeifer in 1970 are part of today's cleft therapy applied by the different schools of surgery.

Arbuthnot Lane.

As part of his series of articles exploring the lives of those behind great surgical innovations, Professor Harold Ellis looks at the work of Sir William Arbuthnot Lane, who was responsible for pioneering many surgical techniques.

Anterior cervical plates: a historical perspective.

The development of anterior cervical plates (ACPs) represents a rapidly changing aspect of spine surgery. This paper focuses on a historical overview of ACPs. The authors discuss the disadvantages of earlier generations of plates and demonstrate how current plates have been designed to overcome the presumed shortcomings of their predecessors. This historical review begins with the earliest plates--unrestricted backout plates--and moves on to newer plates--restricted backout plates and their different subcategories. Virtually all modern ACPs work equally well in cervical stabilization; however, there are differences in design that warrant future studies to understand the long-term performances of different plates.

History of instrumentation for stabilization of the subaxial cervical spine.

In the past several decades methods have been developed to stabilize the subaxial cervical spine both posteriorly and anteriorly. Methods of posterior stabilization have progressed from interspinous wiring, through facet wiring and sublaminar wiring, to the lateral mass screws with plates and rods that are in use today. Plates for anterior stabilization have evolved from rigid plates requiring bicortical screws through those used with unicortical locking screws, to dynamic load-sharing plates used with variable angle screws. The original description of spinous process wiring was published by Hadra in 1891. In 1942 Rogers described the interspinous wiring method used for trauma-induced cervical instability, which was modified by Bohlman in 1985 (triple wiring technique). Luque rods with sublaminar wires were introduced in the late 1970s to address multilevel and occipitocervical instability. Facet wiring was developed in 1977 by Callahan to address the problem of stabilization when laminae are not present. Wiring remained the method used until Roy-Camille introduced the lateral mass screw-plate construct in the 1980s. The first plate for anterior stabilization was designed by Orozco and Llovet in 1970 and was later refined by Caspar; this was a rigid plate with bicortical screws. Morscher devised unicortical locking screws in the 1980s. The latest concept of dynamic load-sharing plates with variable angle screws was developed in 2000. In this article historical landmarks in surgical methods for the stabilization of the subaxial cervical spine are reviewed.

Enhanced tenodesis for retrocalcaneal surgery.

Retrocalcaneal surgery is complex and difficult. Over the years, many different approaches to retrocalcaneal surgery have been described. Partial or total release of the tendo Achillis is often necessary, with reattachment being of paramount importance to allow for optimal function following surgery. Although numerous anchoring devices have been introduced for tendo Achillis reattachment, the authors have found the DePuy TiMAX Spider Plate (DePuy ACE, Warsaw, Indiana) to be superior. This article describes the Spider Plate and associated surgical technique, which have greatly enhanced the outcome of retrocalcaneal surgery.

Repairing holes in the head: a history of cranioplasty.

Cranioplasty is almost as ancient as trephination, yet its fascinating history has been neglected. There is strong evidence that Incan surgeons were performing cranioplasty using precious metals and gourds. Interestingly, early surgical authors, such as Hippocrates and Galen, do not discuss cranioplasty and it was not until the 16th century that cranioplasty in the form of a gold plate was mentioned by Fallopius. The first bone graft was recorded by Meekeren, who in 1668 noted that canine bone was used to repair a cranial defect in a Russian man. The next advance in cranioplasty was the experimental groundwork in bone grafting, performed in the late 19th century. The use of autografts for cranioplasty became popular in the early 20th century. The destructive nature of 20th century warfare provided an impetus to search for alternative metals and plastics to cover large cranial defects. The metallic bone substitutes have largely been replaced by modern plastics. Methyl methacrylate was introduced in 1940 and is currently the most common material used. Research in cranioplasty is now directed at improving the ability of the host to regenerate bone. As modern day trephiners, neurosurgeons should be cognizant of how the technique of repairing a hole in the head has evolved.

The evolution of modern plate osteosynthesis.

Plate osteosynthesis is still recognized as the treatment of choice for most articular fractures, many metaphyseal fractures, and certain diaphyseal fractures such as in the forearm. Since the 1960s, both the techniques and implants used for internal fixation with plates have evolved to provide for improved healing. Most recently, plating methods have focused on the principles of 'biological fixation'. These methods attempt to preserve the blood supply to improve the rate of fracture healing, decrease the need for bone grafting, and decrease the incidence of infection and re-fracture. The purpose of this article is to provide a brief overview of the history of plate osteosynthesis as it relates to the development of the latest minimally invasive surgical techniques.
