High-Resolution Force Plate Analysis of Utilized Slip Resistance in Human Walking

SummaryIntroduction: Partial resurfacing of the humeral head has been reported in humans to treat humeral osteochondritis dissecans. The aim is to describe a custom-made humeral resurfacing prosthesis for treatment of severe humeral head osteochondritis dissecans in a dog.Case report: A seven-month-old female entire St. Bernard dog was presented with a 10 week history of severe left thoracic limb lameness. Radiography, arthroscopy and magnetic resonance imaging confirmed an extensive osteochondritis dissecans lesion affecting the caudal, medial and central regions of the humeral head. A prosthesis designed from computed tomography (CT) images was manufactured in polished stainless steel alloy with a hydroxyapatite coated base and central finned humeral stem for cementless insertion. A standard caudal approach to the shoulder was used to place the prosthesis following reaming of the caudal humeral head.Results: Radiography and CT imaging revealed appropriate topographical placement on the humerus. Force plate analysis demonstrated initial reduction in ground reaction force at six weeks, followed by gradual improvement at three months. There was no radiographic evidence of implant loosening and the range of shoulder joint motion was comparable to the contralateral joint at three months; these findings were maintained to final follow-up at 24 months.Clinical significance: Placement of a humeral head resurfacing prosthesis was an effective technique for the management of severe osteochondritis dissecans-related shoulder lameness. To the authors’ knowledge, this is the first report of the clinical use of shoulder hemiarthroplasty in a dog.

The Way

Seven male subjects ran at 3.0 m/s on a motorized treadmill including a force platform under the tread. The subjects ran at each of five treadmill inclinations: + 0.17, +0.077, 0, -0.077, and -0.17 radians. The position of the subjects’ legs were read from cine´ films (100 frames/s). Results of the film and force plate analysis generally corroborated the “hanging triangle” hypothesis, which postulates that the angle between the leg and the vertical upon foot strike does not change as the treadmill is tipped up or down. A mathematical model of running, in which the leg is represented as a nonlinear spring, made satisfactory predictions of the way many parameters of running change with the treadmill angle, including the length of the leg at touchdown and liftoff and the peak leg force in the middle of a step. The peak leg force reaches a maximum at a treadmill angle near −0.12 radians, close to the downhill angle where other authors have found a minimum in the rate of oxygen consumption.

SummaryA randomized prospective clinical study was performed to compare the effect of surgery for fragmented coronoid process (FCP) and osteochondritis dissecans (OCD) of the canine elbow, with medical treatment using pentosan polysulphate (PPS). Nineteen dogs with FCP and/or OCD of the elbow were randomly assigned to either the surgical or medical group. Lameness examination, radiographic evaluation and force plate analysis were performed at the time of admission, and were repeated at two, four, six and nine months after treatment. In dogs with asymmetrical lameness, in both the medical and surgical groups, the peak vertical forces and mean vertical forces for the more affected limbs were significantly lower than the control means at time zero. In both the medical and surgical group, the peak and mean vertical forces improved during the course of the study. Weightbearing in medically treated dogs approached that in controls at a faster rate than in those treated surgically. After nine months of follow-up, differences could not be detected between the dogs treated surgically, and those treated with PPS.Surgical and medical treatment for fragmented coronoid process and osteochondritis dissecans of the canine elbow were compared. Medical treatment resulted in a more rapid return to normal weight-bearing than did surgical treatment. After nine months of follow-up, differences were not detected between the medically and surgically treated dogs.

SummaryTreatment of cranial cruciate ligament (CCL) rupture using fascial replacement techniques have yielded good clinical results, with 85% to 93% of dogs returning to clinical soundness or intermittent lameness as evaluated by surgeons or owners, but have not been evaluated by force plate analysis long-term. The purpose of this study is to document the long-term clinical and radiographic outcome of dogs having CCL rupture stabilized with an underand- over fascial graft technique by owner assessment, clinical examination, force plate analysis, plain film radiography, and scintigraphy. Twenty dogs with previously repaired unilateral CCL rupture were used for the study. Although client satisfaction was high, force plate analysis revealed significantly lower vertical forces and impulses in the operated versus unoperated limbs. Radiographs and bone scans revealed significant bony changes and synovitis in the operated stifle relative to the unoperated stifle at a median of 17.5 months following repair. Lameness persists in dogs having undergone CCL repair using the under-and-over fascial graft technique; whether this lameness is secondary to progression of osteoarthritis or is a result of surgical repair is unknown.The under-and-over fascial strip technique for stabilization of cranial cruciate ligament-deficient stifles has been evaluated using force plate analysis and nuclear scintigraphy. A median of 17.5 months following surgery, dogs are bearing less weight on the operated limbs as compared to the unoperated limbs. Significant synovitis and bony changes are present when compared to the unoperated limb as evaluated by scintigraphy. Despite these changes, clients are satisfied with the results of surgical repair.
