312 OPEKATIOXS ON MUSCLES AND THEIR ANNEXES. 



result of the presence of clots of blood or other mortified tissues 

 in the wound, and is indicated by the bad apj)earance of the parts, 

 the pecuhar oedematous sweUiug, first warm and painful, but sub- 

 sequently becoming cool and painless. This condition requires 

 promjDt and efficient treatment, both external and internal. 



In /Solipeds. — We once had occasion to resort to crural myotomy 

 for the reHef of a case of pseudo-dislocation of the patella of several 

 months' standing. The division was made towards the lower por- 

 tion of the muscle, and was followed by satisfactory results, though 

 not immediately. 



OPEKATIONS UPON FIBBOUS TISSUES. 



Tenotomy. 



In the terminology of surgery, tenotomy means the sectiofi of 

 tendons — an operation which contemplates the con-ection of de- 

 formities, from whatever cause they may proceed ; the relief of 

 pressure upon exostoses, and the prevention of the complete execu- 

 tion of a normal function, as that of flj^ing in birds. Our atten- 

 tion wiU, accordingly, be directed to the study of the five varieties 

 oi plantar, carpal, antibrachial and tarsal tenotomy, with that of 

 the icings of birds. 



Plantar Tenotomy. 



This operation is the proper remedy for the deformity known 

 as hmickling, or the malposition which arises from the exaggerated 

 flexion of the fetlock joint, and consists in the subcutaneous section 

 of the tendons of the flexor of the phalanges. 



In this affection of knuclding, which is mostly peculiar to 

 sohpeds, there is lameness more or less marked, with a hard and 

 painful enlargem.ent of the tendons, and a consequent interference 

 with the act of locomotion, caused by an incomplete flexion of the 

 articulations. The fetlock is carried forward, and contact with the 

 ground is effected with the toe alone. 



Instances of spontaneous ciu-e or abatement are exceedingly 

 rare. On the contrary, it has a tendency to aggravation, the swell- 

 ing increasing, and the deformity becoming by degrees more and 

 more developed, until at length the anterior face of the wall of the 

 foot rests on the ground, and the case assumes all the well estab-
