Patients who undergo excisional surgical procedures such as femoral head and neck ostectomy (FHO) require a postoperative rehabilitation plan which includes different physical therapy modalities. Therefore, this retrospective study was done to demonstrate the different physical therapy modalities utilized in 20 dogs who were subjected to FHO, and to provide data on the frequency of physical therapy modalities, the protocol duration and time interval from the commencement of physiotherapy and surgery and the patient’s functional recovery. All the protocols included the modalities of thermotherapy (heat), massage, passive stretching and passive joint movement. In the initial phase, electrotherapy and therapeutic ultrasound were most often used, while the water treadmill was continued until the treatment was completed. Physiotherapy sessions varied from 3 to 50 in number, and physiotherapy was commenced from day 5 until day 214 post the surgical procedure. The functional recovery of the limb was in the following range: 65% (13/20) satisfactory, 25% (5/20) partially satisfactory and 10% (2/20) unsatisfactory. Physical therapy treatment was thus concluded to be most influential in the functional recovery of the limb, even if was started late.

“…[3][4][5]14 Currently, the standard of care is to assess adequacy of the excision with intraoperative palpation of the hip joint for bone contact, and postoperative radiographs consisting of standard orthogonal radiographic views of the pelvis (ventrodorsal and lateromedial). 15 Routine ventrodorsal pelvic radiographic views are obtained with the femurs in extension, with the stifles internally rotated. However, this may obscure the distal medial aspect of the femoral neck, a common site of inadequate resection of FHNE, as the beam is no longer tangential to the excision with internal rotation.…”

“…8,16 A radiographic cadaveric study of FHNE in dogs weighing more than 20kg showed that craniocaudal radiographic views with the femur in extension and external rotation (15°, 30°and 45°) dramatically improved the visualization and assessment of adequate ostectomies compared with standard craniocaudal and lateromedial radiographic views. 15 There are anatomical differences in the femurs of cats compared with dogs. Cats have a straighter femur with no isthmus, 14 a shallower acetabulum 17 and the femoral head can have an oval shape as a normal variant.…”

Objective The aim of this study was to determine the effect of femoral position on radiographic assessment of completeness of femoral head and neck excision (FHNE) in cats. Study Design The study included 20 femurs from adult cats. Complete FHNE was performed on 10 femurs and incomplete excision consisting of inadequate excision of the distal medial femoral neck was performed on 10 femurs. The lesser trochanter was maintained in all femurs. Each femur was positioned through a predetermined set of eight radiographic views about the long axis. Sensitivity (SE), specificity (SP) and accuracy were calculated for each femoral position. Results Craniocaudal views of the femur in external rotation (30° and 45°) had the highest SE, SP and accuracy (SE: 97.5% and 97.5%; SP: 92.5% and 95%; and accuracy: 95% and 96%, respectively) followed by external rotation of 15 (SE: 92.5%, SP: 87.5% and accuracy: 90%) relative to standard craniocaudal (SE: 57.5%, SP: 72.5%, accuracy: 65%) and lateromedial (SE: 2.5%, SP: 0%, accuracy: 1%) radiographic views. Conclusions Evaluation of craniocaudal radiographic views with the femurs in external rotation can increase the ability to assess the adequacy of the FHNE in cats.

“…Femoral head and neck excision (FHNE) is commonly performed to treat painful conditions of the coxofemoral joint including aseptic necrosis of the femoral head, chronic hip luxations, osteoarthritis secondary to hip dysplasia, capital physeal and femoral neck fractures, and non-reconstructable acetabular fractures. 1 The goal of the procedure is to eliminate painful contact between the femur and the acetabulum. It is believed that the most common cause of suboptimal outcome is inadequate removal of the femoral neck resulting in persistent bone contact.…”

Objectives This study aimed to compare the completeness of femoral head and neck removal via a craniolateral approach or a ventral approach when femoral head and neck excision (FHNE) is performed by a novice veterinarian. Methods FHNE was performed on both femurs of 10 canine cadavers with each femur randomized by a coin toss to FHNE via the craniolateral or ventral approach. Computed tomography (CT) of the femurs was performed prior to and following FHNE. The volume of bone that should have been removed with an ideal FHNE, the percentage of this volume that remained following FHNE, time to complete the procedure and the number of technical errors were compared between the two groups. Results No significant difference (p = 0.88) was found in the volume of bone that should have been removed with an ideal ostectomy when using the two approaches (craniolateral 3,814.7 ± 409.4 mm3; ventral 3,806.2 ± 479.4 mm3), mean excess residual femoral neck (craniolateral 6.0 ± 9.6%; ventral 4.8 ± 6.8%), mean duration of the procedure (craniolateral 19.3 ± 5.4 minutes; ventral 23.7 ± 5.6 minutes) or number of technical errors (craniolateral 0/10; ventral 1/10) between the craniolateral and ventral approach groups. Clinical Relevance The completeness of bone removal was not significantly different when FHNE was performed by a novice veterinarian via a craniolateral or ventral approach.
