“…9,10 Femoral head and neck ostectomy is currently the most widely reported and performed salvage procedure for feline FCPF. 1,[11][12][13] Studies regarding the outcome of femoral head and neck ostectomy in cats report good-to-excellent medium-to-long-term outcomes based on owners' experience. [14][15][16] However, more objective studies reported muscle atrophy and decreased ground reaction forces in cats after femoral head and neck osteoctomy.…”

Objective The aim of this study was to report the short-term clinical and radiographic outcome for the treatment of femoral capital physeal fractures with cortical positional screws in cats. Study Design Medical records and radiographs of cats with femoral capital physeal fractures stabilized with cortical positional screws were retrospectively reviewed. Signalment, bodyweight, femoral head affected, fracture classification, fracture reduction, implants, concurrent orthopaedic injuries, osteoarthritis, femoral neck osteolysis, complications and 6-week follow-up clinical results were recorded. A short- to long-term follow-up was performed by telephone questionnaire with the owners. Results Forty-six fractures in 39 cats met the inclusion criteria. In 45/46 fractures, radiographic signs of bone healing were present and 35/39 cats were assessed as walking normally by a veterinarian at 6-week follow-up. There was a significant increase in radiographic signs of osteoarthritis (p=0.037) and femoral neck osteolysis (p=0.001) on 6-week follow-up radiographs. Pre- and postoperative osteoarthritis and femoral neck osteolysis were not associated with clinical outcome. The mean follow-up period for the telephone questionnaire was 48 months (range, 5–147 months). Seven out of 25 owners reported a gait abnormality in the short- to long-term. Conclusion Femoral capital physeal fractures in cats can be treated successfully with the use of cortical positional screws. This technique may be considered as an alternative to other primary fixation techniques and salvage procedures for the treatment of femoral capital physeal injuries in cats. This technique seemed successful in cats with a low-grade preoperative femoral neck osteolysis.

“…These typically occur secondarily to physeal dysplasia and metaphyseal disorders, with a higher incidence in overweight, male, neutered cats and in certain breeds of pedigree cat. 30,[35][36][37][38][39][40][41][42] They can usually be identified by the lack of a history of trauma, often progressive clinical signs, a potential for bilateral lesions and signalment. Two pathological entities are described.…”

Feline Femoral Fracture Fixation: What are the options?

Practical relevance: The femur is the most commonly fractured bone in cats. Femoral fractures usually result from high-velocity trauma such as a road traffic accident or fall from a height and, as such, are associated with a wide variety of concurrent injuries. The initial focus of treatment should always be on assessment and stabilisation of the major body systems. Once any concurrent injuries have been addressed, all femoral fractures need surgical stabilisation, with the notable exception of greenstick fractures in very young cats, which can heal with cage rest alone. A number of different surgical options are available depending on the fracture type, location, equipment, surgeon experience and owner finances. Clinical challenges: Femoral fractures can vary hugely in complexity and the small size of feline bones can limit the choice of implants. Furthermore, cats can present unique challenges in the postoperative period due to their active nature and the limited means to control their exercise level. Audience: This review is aimed at general and feline-specific practitioners who have some experience of feline orthopaedics, as well as those simply wishing to expand their knowledge. Aims: The aim of this review is to help clinicians assess, plan and manage feline femoral fractures. It provides an overview of diagnostic imaging and a discussion of a range of suitable surgical options, including the principles of different types of fixation. It also highlights cat-specific issues, approaches and implants pertinent to the management of these cases. Evidence base: A number of original articles and textbook chapters covering many aspects of femoral fractures in cats and dogs have been published. Where possible, this review draws on information from key feline research and, where necessary, extrapolates from relevant canine literature. The authors also offer practical guidance based on their own clinical experience.

“…The treatment of this condition in cats often involves femoral head and neck ostectomy (FHO) (Berzon et al, 1980;Borak et al, 2017;Grayton et al, 2014;Nappier et al, 2019;Rahal et al, 2016). However, a recent study revealed long-term residual gait abnormalities after using this technique (Schnabl-Feichter et al, 2021).…”

“…However, studies have shown that FCPFs in cats can also occur outside of traumatic circumstances, such as physeal dysplasia (or slipped femoral capital epiphysis), and seem to involve different pathophysiological characteristics than those of dogs (Borak et al ., 2017; Craig, 2001; DeCamp et al ., 1989; Gibson et al ., 1991; Lafuente, 2011; McNicholas et al ., 2002; Queen et al ., 1998). The treatment of this condition in cats often involves femoral head and neck ostectomy (FHO) (Berzon et al ., 1980; Borak et al ., 2017; Grayton et al ., 2014; Nappier et al ., 2019; Rahal et al ., 2016).

ObjectivesTo report the short‐term clinical and radiographic outcomes in cats with femoral capital physeal fractures stabilised with transcervical pinning.Materials and MethodsMedical records of cats diagnosed with femoral capital physeal fractures and treated with transcervical pinning were reviewed. The collected data included signalment, weight, time from lameness to surgery, reported trauma, affected side, concomitant orthopaedic injuries, radiographs, osteoarthritis, femoral neck osteolysis, proximal femoral epiphysis to femoral neck ratio, fracture reduction, implants, complications and clinical evaluation results. An owner questionnaire was used for long‐term follow‐up.ResultsNineteen cats with a total of 21 fractures met the inclusion criteria. Fifteen of the 19 cats showed no signs of lameness at the 1‐month follow‐up. Major and catastrophic complications occurred in 9.5% and 23.8% of the fractures, respectively. All catastrophic complications occurred in fractures with a high preoperative osteolysis grade (2 or 3).Clinical SignificanceIn our study, transcervical pinning was found to be a reliable fixation method for the treatment of femoral capital physeal fractures in cats with minimal preoperative femoral neck osteolysis. High rates of implant failure with loss of fracture reduction were observed in cats with high‐grade preoperative osteolysis.
