ABSTRACT

OBJECTIVE: To assess the feasibility of a novel transcoronal approach for the treatment of axial type 3 cysts of the palmar/plantar aspect of the distal phalanx (P3). STUDY DESIGN: Ex vivo, experimental study. SAMPLE POPULATION: Ten cadaveric specimens, four forelimbs and six hindlimbs. METHODS: All cadaveric specimens underwent radiographically guided drilling, followed by cortical screw placement. The cartilage was macroscopically assessed after disarticulation of the distal interphalangeal joint. The entry point and trajectory were evaluated with computed tomography. Results were categorized as: axial, near-axial and abaxial. The minimal distance from the outer margin of the drill hole and the proximal border of the subchondral bone plate was measured using frontal computed tomographic slices. RESULTS: Eight of the 10 screws were in an axial to near-axial position and nine followed the desired axial to near-axial trajectory. One screw was inserted axially but continued in an abaxial trajectory. Iatrogenic damage to the joint cartilage, flexor cortex and solar canal of P3 was not observed. All cortical screws were placed close to the proximal subchondral bone-plate of P3. CONCLUSION: The desired axial/near-axial drilling and screw placement, under radiographic guidance, was achieved in nine out of 10 specimens. CLINICAL SIGNIFICANCE: This novel technique seems promising for the treatment of inaccessible P3 cysts. Additional studies are required to investigate its feasibility in clinical cases, and the long-term outcome following transcystic screw placement of type 3 P3 cysts.

ABSTRACT

A multicentre study of 285 cases was performed to enhance the management of distal phalangeal fractures on the basis of clinical evidence. The outcome after treatment was available for 223 of the cases. Horses with a non-articular type I fracture had a better prognosis (91.7%) for return to original or expected level of use than horses with an articular type II or III fracture (69.6% and 74.1%, respectively). The prognosis for types IV and V fractures was fair (57.7% and 57.1%, respectively) and for type VI good (80%). Horses with a hindlimb fracture had a significantly greater chance of a successful outcome. No significant association between age or time to start treatment and success rate was noted. The best treatment option for types I-III fractures was a conservative approach (box rest). Type IV fractures were best treated by arthroscopic removal of the fragment. Immobilisation of the hoof did not seem to influence outcome. Radiological findings and clinical healing were not accurately correlated and the re-commencement of training should be based on clinical rather than radiological findings. Complete osseous union of the fracture was not essential for a successful return to athletic activity.

ABSTRACT

OBJECTIVE: To evaluate surgical techniques, perioperative complications and outcome of laparoscopic surgery for unilateral and bilateral ovariectomy in mares. STUDY DESIGN: Retrospective multicenter case series. ANIMALS: Mares (n = 157). METHODS: Indications for surgery were neutering, fertility problems, elimination of hormone-related abnormal behavior, ovarian tumors as well as nonregressive ovarian hematomas or cysts. Ovariectomy (n = 206) were performed by a standard laparoscopic procedure in 157 standing sedated mares. Dissection and hemostasis were achieved by using either (1) a linear stapling device, (2) bipolar electrosurgical instruments, with or without a modified Roeder knot, (3) a vessel-sealing system, or (4) a diode-laser with ligation. For some larger ovarian masses (>20 cm diameter), a 2-step surgical procedure was used with standing flank laparoscopic ovariectomy followed by ovarian retrieval through a median celiotomy. Surgical techniques, outcome, and perioperative complications of each method were recorded and analyzed. RESULTS: Laparoscopic dissection of the ovary was accomplished in all mares. Because of the size of the ovarian tumor (n = 7) or in 1 mare with behavioral problems (n = 1), the dissected ovary was removed through a median celiotomy under general anesthesia. Seventeen mares (10.8%) developed postoperative complications (eg, incisional drainage, incisional infection, seroma formation, dehiscence, transient fever and mild abdominal discomfort). All mares with flank incisional problems had ovarian size >12 cm and in 15 (88%) of these mares electrosurgical instruments were used for mesovarial dissection. CONCLUSIONS: Laparoscopic ovariectomy in standing sedated mares provides good surgical access and is associated with low morbidity.
