Surgical management of superficial digital flexor tendon luxation in dogs: 48 cases (2005-2020).

OBJECTIVES: To report the outcome, frequency of complications and potential prognostic factors associated with surgical repair of superficial digital flexor tendon (SDFT) luxation in dogs. MATERIALS AND METHODS: Medical records from 10 referral hospitals were reviewed retrospectively for cases of SDFT luxation in dogs that underwent surgical stabilisation. Signalment, clinical presentation, diagnostic imaging, surgical method, type and length of post-operative limb immobilisation, nature of and length of exercise restriction, presence of post-operative complications and outcomes were recorded. Data were summarised descriptively and prognostic risk factors assessed for association with surgical outcome using risk ratios. RESULTS: Forty-eight cases were included. A successful surgical outcome was recorded in 35 of 48 (73%) cases. Re-luxation of the SDFT occurred in seven of 48 (15%). Six out of 48 (13%) had a persistent lameness despite a stable non-luxating SDFT. A high frequency of post-operative complications occurred (71%), with the majority resolved medically. The risk of surgical failure was 60% higher (risk ratio 1.6, 95% confidence interval 1.1 to 2.4) where absorbable suture material was used compared to non-absorbable suture material. Surgical failure was more common in cases managed with non-rigid immobilisation post-operatively (57% failure) compared to cases managed with rigid immobilisation (19% failure), although this result was not statistically significant. Limb immobilisation of 6 weeks or longer did not significantly affect surgical outcome, compared to shorter periods of exercise restriction or limb immobilisation. CLINICAL SIGNIFICANCE: A good outcome can be expected following surgical stabilisation of SDFT luxation. The use of non-absorbable suture was associated with a more successful surgical outcome.

UNLABELLED: The antro-choanal polyp is a rather common pathology in children. OBJECTIVE: To discuss the diagnostic modalities, the risk factors, the differential diagnoses and treatment options. MATERIAL AND METHODS: This study was performed in an ENT department of a 3rd referal center Fifteen patients, 12 males and 3 females (8 to 16 year old), were treated for an antro-choanal polyp (Killian's polyp) between 1997 and 2007. RESULTS: All patients presented a nasal obstruction. Other signs of discovery were a rhinorrhea, a maxillary pain or a pharyngeal mass. Two patients presented a recurrence after a surgery in another center Atopy did not seem to be a risk factor. The imaging evaluation showed a tissular process developed in the maxillary sinus and extending through the maxillary ostium, or an accessory ostium, toward the nose. All patients were treated by intranasal endoscopic surgery. The middle meatal antrostomy was systematic, associated with a inferior antrostomy in 3 cases, with an anterior ethmoidectomy in one case and with a vestibular approach (Caldwell-Luc procedure) in 4 cases. Two patients presented a recurrence which necessited a new surgery. CONCLUSION: The antro-choanal polyp must be suspected in front of nasal obstruction in children. The imaging evaluation eliminates the main differential diagnoses. The endo-nasal removal seems to be the best procedure.
