Stability assessment of distal radius fractures

Murielle Lafontaine; Dominique Hardy; Philippe Delince

A total of 112 consecutive cases of fractures of the distal radius managed conservatively were graded according to radiological criteria using the first radiograph. These criteria, as well as age over 60 years, were considered as gravity factors. A strong correlation was found between these criteria and the risk of secondary displacement, despite a correct initial reduction.

Bonding of hydroxyapatite-coated femoral prostheses. Histopathology of specimens from four cases

Dominique Hardy; Patrick Frayssinet; André Guilhem; Murielle Lafontaine; Philippe Delince

We examined specimens of hydroxyapatite-coated femoral prostheses from four patients who had died within nine months of implantation for fractured neck of femur. Histology showed newly formed immature bone overlying the hydroxyapatite coating with new trabeculae bridging to the endosteal bone layer. In the diaphysis, where there had been contact between the hydroxyapatite and the cortex, there was dense, firmly anchored bone with an haversian architecture. In other places the newly formed bone had a trabecular structure, containing bone marrow tissue with normal cellularity. It appeared that biological osseointegration had taken place.

Anterior cruciate ligament tears: Conservative or surgical treatment? A critical review of the literature

Philippe Delince; Dior Ghafil

PurposeIs it rational to recommend surgical reconstruction of the torn anterior cruciate ligament to every patient? Is conservative management still a valid option?MethodThrough a literature review, we looked for the arguments from each side and checked their validity.ResultsUnfortunately results of most studies cannot be compared because of the following reasons not exhaustively cited: studied populations differed with respect to age, sex, professional and sports activity level, lesions associated with ACL rupture, patient recruitment methods, time from injury to treatment and different therapeutic modalities. Furthermore, various methods were used to evaluate the clinical and radiological results and there was no consensus of their interpretation. Some authors assumed that the incidence of further meniscus lesions could probably be reduced if the torn ACL was surgically reconstructed. But, we have no evidence to believe that this would be due to the surgical repair rather than to a decrease of involvement in strenuous activities. At present it is not demonstrated that ACL-plasty can prevent osteoarthritis. Numerous factors could explain evolution to arthrosis whatever the treatment for the ACL-ruptured knee. Studies comparing surgical and conservative treatments confirm that ACL reconstruction is not the pre-requisite for returning to sporting activities. More recent and scientifically well-designed studies demonstrate that conservative treatment could give satisfactory results for many patients. They suggest some methods to help them choose the best treatment.ConclusionAt present there are no evidence-based arguments to recommend a systematic surgical reconstruction to any patient who tore his ACL. Knee stability can be improved not only by surgery but also by neuromuscular rehabilitation. Whatever the treatment, fully normal knee kinematics are not restored. While the patients wish to go back to their sport and want everything possible done to prolong their ability to perform these activities, they should be informed that the risk of further knee lesions and osteoarthritis remains high, whatever the treatment, surgical or conservative.Level of evidenceSystematic review of Level I, II, III and IV studies, Level IV.

Two-year outcome of hydroxyapatite-coated prostheses. Two femoral prostheses retrieved at autopsy.

DominiqueC R Hardy; Patrick Frayssinet; Gilbert Bonel; Thierry Authom; Simon A Le Naelou; Philippe Delince

We performed a histological study of the bone-implant interface on 2 human femurs implanted with a hydroxyapatite-coated self-locking stem for 2 years. Extensive bone formation with no intervening fibrous tissue was noted around the entire circumference of the 2 prostheses. The newly-formed bone had 2 morphotypes: an alveolar disposition with a continuous contact between bone and hydroxyapatite, and a digitiform one where distinct bony trabeculae were in contact with the ceramic coating or with the bone marrow. Partial or even total resorption of the hydroxyapatite coating was clearly identified, these areas showing bone in contact with the metal.

Stress Fracture of the Hip: An Unusual Complication of Total Knee Arthroplasty

Dominique Hardy; Philippe Delince; Elizabeth Yasik; Michel Lafontaine

Stress fracture of the hip is a rare complication of total knee arthroplasty (TKA). Only eight cases seem to have been reported in the literature. A ninth case is reported in the present study. A 76-year-old obese woman was treated by right TKA for osteoarthrosis with cementing of the tibial component because of insufficient primary fixation. One year after TKA, she complained of tenderness above the right adductor tendons. There was no history of trauma. One month later, bone scintigrams and roentgenograms demonstrated a stress fracture of the femoral neck. Conservative management was successful. Etiologic factors such as rheumatoid arthritis, osteoporosis, steroid medication, or changes in static or dynamic forces of the hip secondary to knee arthroplasty could not be demonstrated in this patient. The increase in activity after TKA may be a factor in the incidence of these stress fractures of the hip. Radionuclear-type bone scan is helpful in diagnosis. The foci of increased isotope uptake are not always seen at the site of the stress fracture and only later visualized by roentgenograms.

Anterior cruciate ligament tears: conservative or surgical treatment?

Philippe Delince; Dior Ghafil

We thank Maffulli et al. [5] for their comments that reinforce our point of view that one should not systematically and quickly propose surgical treatment to anyone who is a recent victim of an accident causing rupture to the anterior cruciate ligament. This attitude would be defensible if surgery was able to reconstitute the anatomy and physiology of a normal knee, which is not yet the case at present. This is why, as described by Maffulli et al. [5], the sole aim of surgical reconstruction of which the efficacy has been demonstrated is to eliminate instability. It is evident, as we teach our students, that laxity does not necessarily lead to instability and that instability is not always due to laxity. This is the reason why rehabilitation exercises prove effective to treat instability as well demonstrated by different authors [1–4, 6]. Most of our patients are non-professional sportsmen or women who can wait a few weeks before undergoing surgical treatment, which would be, according to some, an indispensable requirement to pursue sporting activities. One must, however, remind them that the return to sports activities after surgical treatment is only effective in 65–70 % of cases. A better selection of candidates for surgical treatment would certainly permit the resumption of sports activities to a proportion of patients nearer to 100 %. This selection can be made with the aid of rehabilitation programmes and self-evaluation questionnaires on the handicap caused by trauma of the knee. The etiology of post-traumatic osteoarthritis is multifactorial, and it is presumptuous to assume that surgical reconstruction of the anterior cruciate ligament would delay or prevent its appearance. It is therefore fallacious to use the argument ‘‘prevention of arthrosis’’ to influence patient’s choice. Specialisation within orthopaedics and techniques becoming easier to apply of course allows improvement of the results of our surgical treatments, but leads also, unfortunately, to a broadening, probably useless, and even maybe harmful, of our indications for surgery. The responsibility of our commercial partners, who often financially support our scientific research, must be underlined when they organise information meetings designed to promote certain techniques and material useful to their realisation. We had presented elements of this literature review to different orthopaedic colleagues who had concluded that we were ‘‘making waves’’ and that this was surgical suicide. The message we would like to transmit is not that we should no longer surgically reconstruct the anterior cruciate ligament, but we should on the one hand improve the selection criteria of candidates for surgery and on the other hand pursue our research and analyze rigorously the results of our studies. We thank again Maffulli et al. [5], who share our opinion on this subject where different varying therapeutic attitudes can sometimes unleash passions. Their support reassures us and allows us not to be considered as icon-breakers.

CT scan evidence of air presence in an epidural hematoma

Paul Edtors; André Grivegnée; Philippe Delince

CT scan evidence of air in an intracranial epidural hematoma is presented. Several conditions could be necessary to induce this unusual pathology: an associated open fracture of the cranial aeric cavities and a positive differential pressure between cavities and hematoma.

Distal Radius Fractures: Evaluation of Instability and Therapeutic Approach

Thierry Authom; Michel Lafontaine; Dominique Hardy; Philippe Delince

For many years, various factors have been considered to be associated with secondary displacement of distal radius fractures. However, the assessment of the instability and the limits of conservative treatment often remain based on the clinical experience of the surgeon. In a previous retrospective study, Lafontaine et al.4 considered 5 supposed severity factors: age over 60 years, dorsal comminution, dorsal angle greater than 20°, intra-articular radio-carpal fracture and fracture of the ulnar styloid process. They found a strong correlation between the sum of these five factors and the risk of secondary displacement after orthopedic reduction and cast immobilization.
