“…Second, medialization of the greater trochanter (MGT) was defined as displacement of the greater trochanter overhanging the central axis of the medullary canal (Figure 1). 18 The presence of MGT was confirmed at surgery because of difficulty entering the femoral canal because of the trochanteric displacement. Finally, deformation of the medial cortex (DMC) was defined as valgus angulation of the proximal femur with lateral deviation of the medial cortex and/or heterotopic consolidation of the femoral head onto the proximal medial femoral cortex (Figure 2).…”

“…When THA is performed for restoration of mobility to dysplastic hips, it provides full return to function in an estimated 95% of dogs, depending on the implant system and generation and surgeon experience 16 . However, performing THA in either chronic CPF or CPF previously treated with FHO or ORIF can be challenging because of secondary remodeling of the acetabulum 3 and/or sclerosis 3,13,17,18 and remodeling of the proximal femur 3,17 . Difficulties have occurred during preparation of the femur, for instance, in which special care was required to enter the femoral canal correctly in the presence of proximal sclerosis 3 …”

Objective To review the outcome of dogs that underwent Zürich cementless total hip arthroplasty (Z‐THA) for the repair of acute and chronic capital physeal fractures (CPF) and document the CPF‐related hip remodeling. Study design Retrospective study. Sample population Fifty‐three Z‐THA in 53 dogs. Methods Medical records of dogs (2006‐2019) that underwent Z‐THA for CPF management were reviewed. Dogs were divided into two groups on the basis of the days elapsed between CPF diagnosis and Z‐THA, acute (≤30 days) and chronic (>30 days). Hip remodeling variables were determined from preoperative radiographs or intraoperatively. Descriptive statistics were performed, and the complication rates, outcome, and coxofemoral remodeling were recorded. Comparisons of remodeling variables and rates between groups were performed by using Fisher's exact test. Results In total, 23 of 53 (43.4%) cases were acute, and 30 of 53 (56.6%) cases were chronic. There was no difference in the femoral remodeling rates between the acute and chronic groups (P = .184), whereas acetabular remodeling was more prevalent in the chronic group (P < .001). Intraoperative complications occurred in four of 53 (7.5% [1/23 acute, 3/30 chronic]) cases, and postoperative complications occurred in six of 53 (11.3% [2/23 acute, 4/30 chronic]) cases. Good clinical outcomes were achieved in 51 of 53 (96.2% [21 acute, 30 chronic]) cases. Conclusion Complication rates of Z‐THA for CPF repair were similar to the complication rates reported for Z‐THA of dysplastic hips. Hip remodeling was common regardless of CPF chronicity. Clinical significance Zürich cementless total hip arthroplasty is viable for surgical management of CPF. There is a high likelihood that hip remodeling will be encountered, even in fractures treated within 30 days of presenting for hind limb lameness.

“…Several improvements in cemented and cementless fixations, designed to decrease postoperative complications, have been proposed, but some of the complications such as aseptic loosening, infections, and luxation are still present (10,11).…”

“…The most common complications for both the cemented and cementless procedure are luxation, acetabular cup displacement, infection, stem or cup aseptic loosening, femoral fractures, acetabular fractures, subsidence (in some systems), and sciatic neurapraxia. On the other hand, the complications described specifically for the case of the cemented procedure include aseptic loosening, cement granuloma, and pulmonary embolism (3,(9)(10)(11)(12)(20)(21)(22)(23)(24).…”

A 7‐year‐old, female, spayed Dogo Argentino was presented with right hindlimb lameness 9 months following right total hip replacement. Investigations identified loosening of the acetabular cup and significant loss of bone stock, including defects of the dorsal acetabular rim and caudal pillar. A custom‐made acetabular cage inspired from the human acetabular reinforcement ring was implanted and fixed into the ilium and the acetabular rim with screws. Improvement in right hindlimb function was delayed by the occurrence of a right cranial cruciate ligament rupture; however, radiography 6 months following the surgery demonstrated osseointegration despite loosening of a single screw. Three years postoperatively, the dog showed no resentment on manipulation of the right hip and the owners reported a return to normal activity including off‐lead running. Aseptic cup loosening associated with acetabular medial wall and caudal pillar defect were ameliorated using a custom‐made acetabular cage in a giant breed dog.
