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.

SummaryTriple pelvic osteotomy (TPO) was used in the treatment for traumatic coxofemoral luxations in four adult, large breed dogs with hip dysplasia. Initial closed reductions failed in three and one dog had an initial closed reduction and subsequent open reduction of the coxofemoral luxation that failed. Hip dysplasia was thought to be a prominent factor contributing to the reluxation. TPO successfully maintained reduction of the coxofemoral luxation in all of the dogs. An increase in dorsal acetabular coverage of the femoral head following TPO was demonstrated by an increased Norberg angle. The improved congruency was thought to maintain reduction of the femoral head in the acetabulum and decrease stresses on the joint capsule, allowing healing to occur. Long-term (median: 343, mean ± SD: 406 ± 226 days follow-up) function of the affected limb was comparable to the contralateral limb. Three of the four dogs did not have radiographic progression of coxofemoral degenerative joint disease of the affected joint and differences in the progression of degenerative joint disease were not evident between the affected and the contralateral coxofemoral joint. A decrease in abduction and external rotation and an increase in internal rotation following TPO was noted in the affected coxofemoral joint. Our results establish the utility of this procedure in dysplastic dogs with traumatic coxofemoral luxations.Triple pelvic osteotomy used in the treatment for traumatic coxofemoral luxation in four adult, large breed dogs with hip dysplasia successfully maintained reduction and resulted in satisfactory limb function in all patients.

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.

Force Plate Data

Introduction A simple tool to estimate loading on the lower limb joints outside a laboratory may be useful for people who suffer from degenerative joint disease. Here, the accelerometers on board of wearables (smartwatch, smartphone) were used to estimate the load rate on the lower limbs and were compared to data from a treadmill force plate. The aim was to assess the validity of wearables to estimate load rate transmitted through the joints. Methods Twelve healthy participants (female n = 4, male n = 8; aged 26 ± 3 years; height: 175 ± 15 cm; body mass: 71 ± 9 kg) carried wearables, while performing locomotive activities on an anti-gravity treadmill with an integrated force plate. Acceleration data from the wearables and force plate data were used to estimate the load rate. The treadmill enabled 7680 data points to be obtained, allowing a good estimate of uncertainty to be examined. A linear regression model and cross-validation with 1000 bootstrap resamples were used to assess the validation. Results Significant correlation was found between load rate from the force plate and wearables (smartphone: [Formula: see text]; smartwatch: [Formula: see text]). Conclusion Wearables’ accelerometers can estimate load rate, and the good correlation with force plate data supports their use as a surrogate when assessing lower limb joint loading in field environments.

SummarySurgical procedures such as total hip arthroplasty (THA) or femoral head and neck excision may be indicated as a treatment for traumatic coxo-femoral luxation that is complicated by pre-existing joint disease, concurrent fractures or recurrent luxation. The purpose of our study was to evaluate outcome after treatment of traumatic coxo-femoral luxation by THA. Medical records of dogs undergoing cemented THA from 1996 to 2002 were reviewed. Inclusion criteria were coxofemoral luxation resulting from severe external trauma and radiographic follow-up of at least 3 months. Ten dogs (12 THA) met the criteria for inclusion. Complications included THA luxation (n = 1) and a non-displaced peri-prosthetic femoral fracture (n = 1) that healed without further surgery. Median cumulative function scores from client questionnaires after THA were not significantly different in dogs with previously normal (8, range: 7-10), (n = 5) and dysplastic (9, range: 7–16), (n = 5) hips (P = 0.410). Six dogs were available for re-examination and force plate analysis at greater than 6 months post-THA, and none of these dogs had any visible lameness. Peak vertical force (% BWt) showed a trend towards being less in THA (60.8±5.1) than non-operated (68.1±6.1) hindlimbs (P = 0.057), whereas vertical impulse (% BWt x sec) was similar in THA (9.1±1.6) and non-operated (9.8±1.2) hindlimbs (P = 0.286). Our findings indicate that THA can be a successful treatment for traumatic coxo-femoral luxation, irrespective of the dysplastic status of the joint prior to injury.

Cranial Cruciate Ligament Rupture

Sixty-one large dogs (weighing 22.7 kg or more) with cranial cruciate ligament ruptures (CCLRs) were treated with either fibular head transpositions (FHTs; n = 22 stifles), lateral fabellar sutures (LFSs; n = 39 stifles), or conservatively (CT; n = 11 stifles) with rest and aspirin. Based on owner evaluation, dogs treated with FHTs or CT did not perform as well as dogs treated with LFSs (p less than 0.05). There was no difference in owner evaluation scores for the dogs treated with FHTs or CT. Thirty dogs were reevaluated by investigators. No differences between treatment groups regarding age, sex, or time until diagnosis were noted. No differences in scores for lameness, stifle instability, or forceplate analysis among the treatment groups were observed. Degenerative joint disease progressed or remained severe regardless of treatment, based upon radiographic evidence.

Cervical Area

Specimens of ligamentum flavum, joint capsule, and dorsal lamina were collected at surgery or necropsy from 25 horses with cervical static stenosis. All horses had myelographic evidence of dorsal compression of the spinal cord caused by soft tissue and/or bone in the caudal cervical area, primarily at C6-7. Most horses also had radiographic evidence of degenerative joint disease of articular facets. Histologically 19 horses had osteosclerosis and cartilage retention in the dorsal lamina, and 24 horses had increased fibrocartilage at the ligamentum flavum attachment to dorsal lamina. The ligamentum flavum and joint capsule had fibrovascular tissue in 20 horses. Fibrocartilaginous tissue, old hemorrhage, and fat necrosis were not unusual. One horse each had a synovial cyst, eosinophilic granulomas in the joint capsule, and osteochondrosis of articular facets. These findings indicate that abnormal biomechanical forces or instability of articulations result in stretching and tearing of the ligamentum flavum and joint capsule with subsequent fibrovascular and fibrocartilaginous proliferation, osteosclerosis of the dorsal lamina, and osteophyte formation on the articular facets.

End Stage

Metatarsophalangeal (MTP) arthrodesis was done in each of three dogs with end-stage degenerative joint disease resulting from trauma and osteomyelitis (n = 2) and immune-mediated disease (n = 1). In two cases, MTP arthrodesis proved to be a useful method of eliminating pain and salvaging limb function. In one case, concurrent injuries and obesity prevented full return to function. Arthrodesis was accomplished with autogenous cancellous bone grafts and bone plates (n = 2) and with transarticular K-wires (n = 1). External coaptation was a necessary adjunct to internal fixation in all cases.
