Closure of clival cerebrospinal fluid fistula with biocompatible osteoconductive polymer.

Cerebrospinal fluid fistula into the upper airway often results in meningitis. Closure of fistulas is usually effective using conventional surgical techniques to reconstruct the defect. We report a case of cerebrospinal fluid fistula into the sphenoid sinus and nasopharynx secondary to resection of a clivus chordoma that resisted conventional attempts at closure, including a rectus abdominus free flap. Closure of the fistula was accomplished with the use of a novel alloplast, biocompatible osteoconductive polymer. Follow-up for more than 1 year shows no evidence of rejection, infection, or recurrent cerebrospinal fluid rhinorrhea.

Sertl shelf arthroplasty (BOP procedure) in the treatment of canine hip dysplasia.

The BOP/Sertl shelf arthroplasty procedure is not difficult or lengthy. It uses minimal metallic fixation. It is quite physiological with minimal morbidity because there is no change in the bony anatomic pelvis except to create an extension of the lateral rim of the acetabulum. The animal is able to walk the day after surgery. The procedure can be performed bilaterally the same day, thus creating good bony stability and decreasing stretching of the joint capsule, which in turn prevents further subluxation and pain in the hip joint. The aim of this procedure is to return the animal to a satisfactory lifestyle through an effective but less complicated surgical procedure as compared to other available options. This procedure is straightforward and can be done by a surgeon who is familiar with orthopedic surgical techniques and has been trained in this procedure. To date, more than 150 veterinarians have had hands-on training to perform this operation. We are not claiming that this procedure is a cure for CHD; rather, it is a procedure that dramatically slows down the progress of this malady and allows the dog to lead a more normal lifestyle and avoids euthanasia. After 51 months, our study of 200 hips has had a success rate of 99% on the animals available for follow-up as evidenced by returning those animals to a satisfactory lifestyle with stable hips.

Percutaneous interbody osteosynthesis in the treatment of thoracolumbar traumatic or tumoural lesions. A review of 51 cases.

The authors describe a technique of percutaneous interbody osteosynthesis applicable to the dorsal and lumbar spine. 51 patients were so treated for different aetiologies: traumatic conditions (35 cases) and tumoural lesions (16 cases). The material used consisted of special instruments that are positioned in double obliquity by a percutaneous posterolateral approach. A posterior approach limited to the pathological focus was used jointly whenever a graft or a decompression was necessary (19 cases). Several types of anaesthesia were used (local, local-regional, general, neuroleptanalgesia). The patients benefited by the advantages that usually accompany percutaneous techniques. The advantages and limitations of the method are discussed.

Discectomies of the lower cervical spine using interbody biopolymer (B.O.P.) implants. Advantages in the treatment of complicated cervical arthrosis. A review of 150 cases.

The authors report their experience with 150 cases of discectomies performed with interbody grafts using a copolymer (Biocompatible Orthopedic Polymer or BOP). Made of N-Vinylpyrrolidone-Methylmethacrylate monomers, polyamide fibres and calcium gluconate. BOP is a biocompatible, biodegradable, osteoconductive matrix, easy to use and quite safe. These properties are quite well appreciated for cervical interbody grafting. After discectomy, stabilization of the spine is immediate, and fusion slowly occurs around and through the biopolymer within one year. The biomaterial avoids morbidity inherent in the harvesting of an autograft, as well as any limitations resulting from the use of allografts.

The use of a biocompatible orthopaedic polymer in the treatment of loose total hip prostheses.

Seventeen cases of loose total hip prostheses were treated with biocompatible orthopaedic polymer, an osteoconductive co-polymer. Biocompatible orthopaedic polymer permits improved stability and secondary bone repair and may also act as a vehicle for adjunctive antibiotic therapy. The available forms of biocompatible orthopaedic polymer and their methods of application are described and the results obtained with their use are compared with the pre-operative clinical observations. Of the 17 patients studied, pain disappeared in 14, unlimited walking became possible in seven, while another eight patients were subsequently able to walk for over 300 m. Mobility became normal in 13 cases; full weight bearing on one leg became possible in 12 cases and became normal in another four. Radiological examination showed the development of a bony interface between the cortex and the prosthesis as the radiolucent biocompatible orthopaedic polymer material was converted into bone. It may, therefore, be concluded that, in this indication, biocompatible orthopaedic polymer appears to be an active interface for stabilizing loose total hip prostheses.

Traumatic hip dislocation with ipsilateral femoral shaft fractures.

A traumatic dislocation of the hip joint associated with an ipsilateral femoral shaft fracture is a rare injury resulting from severe trauma. Initially the dislocated hip joint is often unrecognized and consequently reduction is delayed. Early diagnosis and reduction of the hip joint improves the functional prognosis. The maximum functional recovery is possible only with greater awareness of this combined injury. Examination of the hip joints by clinical roentgenography in the critically injured patient, especially those with head injuries, or physical signs masked by extremity swelling, should be a routine procedure.
