Excision Arthroplasty

SummaryThe long-term efficiency of conservative treatment, excision arthroplasty of the femoral head and neck and triple pelvic osteotomy for the treatment of hip dysplasia in the immature dog were compared using ground reaction forces analysis at the trot. Fourteen hips were re-evaluated for the conservative treatment group, 16 for the triple pelvic osteotomy group and ten for the excision arthroplasty group. Force plate analysis demonstrated that hind limbs belonging to the triple pelvic osteotomy group had, at the trot, a locomotor function similar to the one of normal hind limbs in the control group. At a “similar age”, hind limbs of the conservative group did not show any marked difference from those in the triple pelvic osteotomy and control groups. The dogs of the excision arthroplasty group showed ground reaction forces abnormalities, most probably due to the absence of a coxofemoral joint (decreased peak propulsive force and Fz impulse, compared to triple pelvic osteotomy and control groups). The forelimbs of conservative treatment, excision arthroplasty and triple pelvic osteotomy groups showed a peak propulsive force superior to the one in the control group. This could be an adaptation phenomenon in order to compensate a deficient function of the hind limbs or a habit acquired at a younger age.Force plate analysis has demonstrated that hind limbs treated bilaterally with triple pelvic osteotomy had, at the trot, a locomotor function similar to the one of normal hind limbs from a control group. At a mean age of 4.5 ± 1 years, dogs treated conservatively did not show, at the trot, any marked difference with those treated with triple pelvic osteotomy and with normal dogs. Hind limbs treated with excision arthroplasty showed certain abnormalities most probably due to the absence of a coxofemoral joint such as a significant decrease of peak propulsive force and Fz impulse.

Background: The purpose of this case series was to quantify gait to study muscular dystrophy. In this research, the quantitative differences between normal and waddling gaits were assessed by force plate analysis. Methods: Nineteen myopathy patients and 20 normal subjects serving as the control group participated in this research. In this study, quantitative analyses of gait have been used to investigate the differences in mobility between normal subjects and myopathy patients. Patient data were collected from Iranian Muscular Dystrophy Association members, and normal data were extracted from students of Azad University. All of the gait tests were performed using a Kistler force platform. Participants walked at a self-selected speed, barefoot, independently, and without assistive devices. Results: Our findings indicate that there were no significant differences between the patients and the control group in the anterior–posterior components of the ground reaction forces; however, there were considerable differences in the force components between the groups in the medial-lateral and vertical directions of the ground reaction force. In addition, there were significant differences in the time parameters between the groups along the vertical and medial-lateral directions.

SummaryThe efficiency of conservative treatment, excision arthroplasty of the femoral head and neck and triple pelvic osteotomy for the treatment of hip dysplasia in the immature dog were compared using locomotor, physical and radiographic examinations and owner’s evaluation. Cases selected for this study were dogs diagnosed with bilateral hip dysplasia, initially admitted with clinical signs (lameness, pain), immature at the beginning of the treatment (less than 12 months of age), with both hips subjected to the same treatment (conservative treatment, excision arthroplasty of the femoral head and neck or triple pelvic osteotomy). These dogs never showed any musculoskeletal problems other than hip dysplasia and the surgical treatment had been completed at least 20 months prior to re-evaluation time. Fourteen hips were re-evaluated in the conservative group, 16 in the triple pelvic osteotomy group and ten in the excision arthroplasty group. Locomotor, physical and owner’s evaluations demonstrated the superiority of the triple pelvic osteotomy. These evaluations also showed that excision arthroplasty was more efficient than conservative treatment. Radiographic examination demonstrated the obvious superiority of the triple pelvic osteotomy over conservative treatment.Locomotor, physical and owner’s evaluations demonstrated the superiority of the triple pelvic osteotomy over conservative treatment and excision arthroplasty for the treatment of hip dysplasia in the immature dog. Radiographic examination demonstrated the obvious superiority of the triple pelvic osteotomy over conservative treatment for joint congruence and control of degenerative joint disease.

Abstract Objective The aim of this study was to compare outcomes after tibial plateau levelling osteotomy (TPLO) and modified Maquet procedure (MMP) for the treatment of cranial cruciate ligament rupture (CCLR) in dogs using clinical and radiographic evaluation and treadmill-based force plate gait analysis. Study Design This study was a prospective, randomized, controlled study. Materials and Methods Sixty-one dogs (76 joints) with CCLR were treated with TPLO (n = 30 dogs, 41 joints) or MMP (n = 31 dogs, 35 joints) and compared with a control group of 16 healthy Labrador Retrievers. Outcomes after surgery were compared by clinical orthopaedic assessment, radiographic evaluation and force plate gait analysis performed preoperatively, and then at 6 weeks, 3 and 6 months postoperatively. For objective comparison of ground reaction forces, the data were compared with the control group. Major complications were reported. Results A significant improvement in ground reaction forces was reached in all surgically treated dogs. No significant difference was found between the surgical methods at any postoperative re-examination. With regard to peak vertical force (PVF), there were significantly more patients with TPLO within the reference range of healthy dogs at the 3 months re-examination than dogs with MMP. There was no significant difference in mean value comparisons between TPLO and control groups 6 months postoperatively. Compared with the control group, mean values of 93.9% (PVF) and 85.9% (vertical impulse [VI]) were reached by the TPLO group and 89.4% (PVF) and 79.9% (VI) by the MMP group, 6 months postoperatively.No significant differences were found regarding major complications or progression of osteoarthritis. Conclusions Although no significant differences were found between the surgical methods, TPLO patients showed superiority with regard to clinical outcome.

The objective of this study was to evaluate prospectively the outcome of 21 clinical patients treated with triple pelvic osteotomies during the year following surgery. Specific aims included documenting the time of and extent of improved limb function as measured by force plate analysis, evaluating the progression of degenerative joint disease (DJD) in the treated and untreated coxofemoral joints, and determining whether or not triple pelvic osteotomy resulted in degenerative joint changes in the ipsilateral stifle and hock. Twelve dogs were treated unilaterally and nine dogs were treated bilaterally with triple pelvic osteotomies. There were no differences in mean anteversion angles, angles of inclination, or preoperative DJD between treated hips and untreated hips. Degenerative joint disease progressed significantly in all hips regardless of treatment. Two cases developed hyperextension of their hocks after the triple pelvic osteotomies. However, no radiographic evidence of DJD was observed for any of the stifles or hocks at any observation time. A significant increase in vertical peak force (VPF) scores was noted for treated legs by two-to-three months after surgery, which continued over time. Untreated legs did not show a significant change in VPF scores over time. No differences were found in progression to higher scores when unilaterally treated legs, first-side treated legs, and second-side treated legs were compared.

Cranial Cruciate Ligament Rupture

Introduction Cranial cruciate ligament failure is one of the principal causes of canine lameness. Several surgical procedures were proposed to achieve joint stabilisation; among these, the Modified Maquet Procedure involves using a titanium foam wedge to achieve and maintain the tibial tuberosity advancement. The force-plate analysis provides to objectively assess normal and abnormal gait and the outcome of different surgical techniques. The study evaluates the outcome of limbs that underwent Modified Maquet Procedure using land-force plate analysis comparing the operated limb with its healthy contralateral one as a control. Materials and methods Thirty-five dogs with unilateral cranial cruciate ligament rupture were evaluated. Outcome after surgery was assessed by orthopaedic and radiographic evaluations and force plate gait analysis performed before surgery, at 15, 30 and 90 days after surgery. For objective comparison of ground reaction forces, data of operated limb were compared to contralateral limb on each time control and Symmetry Index at 90 days was determined. Healing radiographic signs, minor and major complication were reported. Results A significant improvement in ground reaction forces was reached in all the treated limbs between set time intervals. The median percentage increase in ground reaction forces was constant from 15 to 90 days, with a Symmetry Index >9 in 54.2% of patients suggesting a normal gait symmetry. A complete bone healing was noticed at 90 days follow-up radiographic assessment. We experienced three major (8.5%) and one minor (2.8%) complications. Conclusions To the Authors’ knowledge, this is the first study in the veterinary literature that assessed outcomes of dogs undergoing Modified Maquet Procedure for the treatment of cranial cruciate ligament rupture using force plate gait analysis and healthy contralateral limb as a control group. Our results confirm that Modified Maquet Procedure is an effective method to stabilise the stifle joint.

SummaryIn this prospective study force plate analysis was used to investigate the locomotor aspects of unilateral fragmented medial coronoid process (FCP) and the effects of surgical treatment in seven dogs. The diagnosis unilateral FCP. was based on clinical and radiological examination of both elbow joints and confirmed during surgery. Radiological screening of the elbow joints was repeated at six months after surgery to determine the osteoarthritis (OA) score and to exclude any bilateral involvement. Force plate analyses were performed at three consecutive intervals: prior to surgery, at six weeks and at six months after surgery. The peak braking force Fymax, peak propulsive force-Fymin, peak vertical force-Fzmax and the corresponding impulses Iymax, Iymin and Iz were determined. The symmetry index SI of these forces and impulses (ratio affected side : contralateral side) in the front limbs was assessed to evaluate the locomotion. The combination of the Sis of Fymin, Fymax, Iymin, Iymax and Iz proved to be more sensitive in determining front limb lameness due to unilateral FCP than the SI of the peak vertical force Fzmax. The SI of Fzmax had returned to within the normal range at six months after surgery for all seven dogs, whereas the other parameters showed persisting abnormalities in two dogs. In this study the improvement after surgical treatment of the SI of both Fymin and Iymin was significant at P<0.05. All of the joints showed progressive radiological signs of OA at six months after surgery.The effects of unilateral fragmented medial coronoid process on the ground reaction forces of the front limbs and the effects of surgical treatment were evaluated using force plate analysis. Surgical treatment seemed to have a favorable outcome, despite radiological progression of osteoarthritis.

Introduction. There are no guidelines for treating bacterial infections in our country. Antibacterial drugs are selected empirically, which is not always in accordance with the recommended therapy coming from the countries that have their own pharmacotherapy protocols. This study reviews the differences between the standard conservative treatment of cholangitis/cholecystitis and treatment implemented in accordance with current pharmacotherapy guidelines of other countries. The assessment of the therapeutic efficacy of antibacterial drugs implemented in the treatment of cholangitis/cholecystitis and economic viability of that implementation was one of the aims of this study, and another one was comparison of the efficiency and cost of medical treatment using physician?s therapy of choice and treatment according to pharmacotherapy guidelines. Material and Methods. The study was carried out over a threeyear period at the Department of Infectious Diseases of the Clinical Center of Vojvodina. It included 72 patients with the diagnosis of cholangitis/cholecystitis who were divided into two groups. The control group was treated according to the physician?s therapy of choice, while the test group was treated in accordance with pharmacotherapy guidelines. The efficiency and cost of medical treatment were determined for both groups. Results. The comparison of the efficiency and costs of medical treatment of cholangitis/cholecystitis before and after introducing pharmacotherapy guidelines showed no significant differences in the efficiency of administered therapies. However, the cost of medical treatment carried out in accordance with pharmacotherapy guidelines showed a decrease of 17.24%. Conclusion. Medical treatment using physician?s antibacterial therapy of choice and the one which is in accordance with pharmacotherapy guidelines for treating cholangitis/cholecystitis show no differences in terms of efficiency. However, medical treatment proved to be more affordable in the group of patients treated in accordance with pharmacotherapy guidelines of other countries.

Background: This pilot study aimed to assess quantitative differences between normal and steppage gait by analyzing force plate data. Materials and Methods: We studied 25 subjects with drop foot, who were treated in the orthopedic center for drop foot brace. Twenty healthy students were included as a control group. There were no differences in the age, weight, height, and body mass index between the patients and the controls (p > 0.05). They walked at self-selected speed with a mean of 10 trials (+2) to collect their ground reaction forces data by force plate. Results: There were no significant differences between the groups in antero-posterior component of ground reaction force (p > 0.05). There was significant relationship between the time parameters in vertical and medio-lateral components of ground reaction forces (p < 0.05). We have found that the medio-lateral impulse in the patients group is negative (p < 0.05), which means instability in patients' gait. Conclusion: The result of this research reveals that the analysis of ground reaction force quantitatively describes steppage gait. The average stance time among patients is longer than control group. Further work with a larger database of subjects is required to confirm our findings.

Swing Speed

Golf is a sport which requires players to use ground interaction to generate clubhead speed in order to propel the ball towards the target. Force platforms are a technology which can be used to measure these ground reaction forces. Golfers generate force through a combination of jumping, sliding or twisting actions during the swing. Understanding how golfers generate these forces and if there are any groups which golfers could be clustered into could be used to enhance golf instruction as well as clubhead design or fitting practices for golf equipment. A total of 105 right-handed experienced golfers (handicap mean = 8.32 ± 8.31) consented to participate in the study of different swing speeds (31 below 95 mph, 41 over 105 mph and 33 between 95 and 105 mph). A calibrated single force plate was used for the test which sampled at 1000 Hz and recorded force and moment data in three axes. After a self-guided warm up, the players were instructed to hit five 7-iron shots and five drives to the best of their ability in an indoor hitting bay which used a launch monitor to record the club delivery and ball flight information. It was found that handicap or swing speed did not dictate the primary force production mechanism (sliding, jumping or twisting/spinning). This knowledge could aid engineers to design equipment better suited to the individual and help coaches build individualized programs to create power and clubhead speed in all players.
