Revision ACL reconstruction: influence of a lateral tenodesis.

Purpose: The aims of this article were to report the objective results of revision ACL reconstruction and to assess the influence of an associated lateral extra-articular tenodesis on knee stability and IKDC score.

Methods: This study focused on revision ACL reconstruction and was conducted over a 10-year period, from 1994 to 2003 with ten French orthopedic centers participating. The minimum follow-up required was 2 years.

SHART: shoulder hyperabduction radiological test.

Purpose: To evaluate and quantify laxity of the inferior glenohumeral ligament (IGHL) in post-traumatic anterior instability of the shoulder with the shoulder hyperabduction radiological test (SHART) and correlate it with arthroscopic findings.

Methods: This prospective study included 21 patients undergoing arthroscopic stabilization for anteroinferior shoulder instability. The SHART test was performed as follows: a bilateral AP radiograph was performed in the supine position, and radiographs were compared.

Causes for failure of ACL reconstruction and influence of meniscectomies after revision.

The purpose of this multicenter retrospective study was to analyze the causes for failure of ACL reconstruction and the influence of meniscectomies after revision. This study was conducted over a 12-year period, from 1994 to 2005 with ten French orthopaedic centers participating. Assessment included the objective International Knee Documenting Committee (IKDC) 2000 scoring system evaluation.

[Recurrent anterior instability of the shoulder associated with full thickness rotator cuff tear: results of surgical treatment].

Purpose Of The Study: Recurrent anterior dislocations associated with full thickness rotator cuff tear (RCT) carry a difficult therapeutic problem: should we treat instability and rotator cuff tear at the same time or only one of both pathologies? The goal of this study was to analyse a retrospective series of patients operated on to try to answer this question.

Material And Methods: Twenty-eight shoulders (27 patients) were operated on between 1988 and 2002. The mean age at first dislocation was 47 years (16-65), the average delay between first dislocation and operation was 6.

[Arthroscopic tightening of the anterior cruciate ligament].

We present here the preliminary results obtained with arthroscopic tightening of the anterior cruciate ligament. Six patients underwent the technique. Four had had prior ligamentoplasty, two had sequelae of tibial spine fractures.

Long Term Outcomes after Arthroscopic Management of Tibial Plateau Fractures.

Objectives: Tibial plateau fractures are efficiently treated using arthroscopy when limited to one condyle. Operative technique and early results are now well documented. However, long term results have not been widely reported.

[Double localization of an osteoid osteoma of the ankle: percutaneous treatment by CT-guided drilling].

A 26-year-old woman presented a rare double localization of an osteoid osteoma of the ankle. The first focus was situated in the tibial metaphysic, bordering the distal tibiofibular joint. The second focus was also superficial, located in the neck of the homolateral talus.

[Endoscopic treatment of snapping scapula].

We describe an endoscopic method for resection of the superomedial comer of the scapula in cases of painful snapping scapula. A preoperative computed tomography may be useful to show narrowing between the superomedial comer and the chest wall. Endoscopic technique gives the same goods results than open surgery with in cosmetic advantage and early rehabilitation.

[Endoscopic treatment of snapping scapula.].

We describe an endoscopic method for resection of the superomedial corner of the scapula in cases of painful snapping scapula. A preoperative computed tomography may be useful to show narrowing between the superomedial corner and the chest wall. Endoscopic technique gives the same goods results than open surgery with in cosmetic advantage and early rehabilitation.

Pasteurella multocida infection of a total knee arthroplasty after a "dog lick".

The patient we report here underwent a total knee arthroplasty (TKA) which got infected with P. multocida after her dog had licked a small wound at the third toe of the same foot. Despite a correct treatment comprising synovectomy and cleansing, and an active antibiotic treatment for 3 months, the patient was readmitted for persistent infection of the same knee 2 weeks after the end of the antibiotic treatment.

[Medial approaches to the distal humerus for fracture fixation].

Purpose Of The Study: We report our experience with the medial and medioposterior approaches to the humeral diaphysis for plate fixation of the proximal humerus.

Material And Methods: Fifteen patients were treated for shaft fracture (n=13) or nonunion (n=2) of the distal third of the humerus without radial nerve involvement. The medial approach was performed in the supine position and the medioposterior approach in the prone position.

Computer simulation of arcuate keratotomy for astigmatism.

Background: The development of refractive corneal surgery involves numerous attempts to isolate the effect of individual factors on surgical outcome. Computer simulation of refractive keratotomy allows the surgeon to alter variables of the technique and to isolate the effect of specific factors independent of other factors, something that cannot easily be done in any of the currently available experimental models.

Methods: We used the finite element numerical method to construct a mathematical model of the eye.

Preliminary computer simulation of the effects of radial keratotomy.

We created a computerized mathematical model of the eye for the simulation of refractive surgery. This model used a slightly prolate shape for a moderately myopic eye and an idealized aspheric profile for the cornea. The finite element method and the nonlinear Mooney-Rivelin law were used to analyze stress-strain relationships.

Computer simulation of arcuate and radial incisions involving the corneoscleral limbus.

We have created a computer model of the eye that improves upon previous models with two assumptions: (1) the cornea is considered anisotropic, and (2) the strain tensor is non-linear for large displacements. Values used include those for Young's modulus, Poisson's ratio, and three coefficients of anisotropia. A finite element computer program was used to stimulate the behaviour of the eye.
