The anatomical structure of pelvic limb, of thirty-one adult Korean native goats (Body weight: 14~17kg) was observed after skeletal preparation, and the osteometry was performed in each bone. The results were as follows: 1. The pelvic limb of the Korean native goat was composed of the hip bone, femur, patella, tibia, fibula, tarsal bones, metatarsal bone, phalanges and sesamoid bones. 2. The hip bone consisted of the ilium, ischium and pubis which fused each other, The gluteal surface of the ilium was directed dorsolaterally. The tuber sacrale and tuber coxae were formed at the dorsal apex and ventrolateral part of the iliac wing, respectively. The lesser ischiatic notch was deeper than the greater one. The ischiatic tubercles were triangular form and consisted of the dorsal, lateral and caudal ischiatic tubercles. The left and right hip bone indexes were 67.08, 66.20, the acetabular indexes were 93.78 and 92.10 and the obturator foramen. indexes were 53.84 and 54.77, respectively. 3. In femur, both of the greater and lesser trochanter were well developed but the third trochanter was not observed. The left and right femur indexes were 26.55 and 26.14, head indexes were 81.66 and 81.49 and the trochlear-epicondyle indexes were 42.47 and 41.63, respectively. 4. The patella was observed as an isosceles triangle with base lying proximal and the cranial surface was more convex. 5. The tibial shaft was sigmoid form and the popliteal notch was deep. There was a large nutrient foramen at the cranial aspect of the cranial intercondylar area. The tibial indexes were 22.09 in left and 21.10 in right. 6. The proximal extremity of the fibula was fused with the lateral condyle of the tibia but the distal one was observed independently as the malleolar bone. 7. The tarsal bones were five in number; the talus, calcaneus, centroquartal tarsal bone, first tarsal bone, and second-third tarsal bone. 8. The metatarsal bone was composed of a large metatarsal bone. resulted from the fusion of the third and fourth metatarsal bones, The structure of metatarsal bone was similar to the metacarpal bone but longer about 7mm. 9. The phalanges and sesamoid bones were similar to these of the thoratic limb. 10. The ratios of the lengths among the hip bone, femur, tibia and metafarsal bone were 1.71 : 1.54 : 1.73 : 1.00 in left and 1.68 : 1.53 : 1.72 : 1.00 in right, respectively.

Purpose: Nerve conduction study (NCS) test is a standard diagnostic study of the tarsal tunnel syndrome. The purpose of this study was to determine the relation between the results of the NCS and postoperative clinical results. Materials and Methods: From June 2004 to July 2015, 104 patients were diagnosed with tarsal tunnel syndrome and treated surgically. Of 104 patients diagnosed through NCS preoperatively and postoperatively, 41 patients were included in this study. There were 23 male and 18 female patients with mean age of 49.2 years old and the average follow-up period was 15.5 months. NCS, pain visual analogue scale (VAS) score, and subjective satisfaction were examined preoperatively and postoperatively. Results: On the preoperative NCS, 32 patients (78.0%) were positive and 9 patients (22.0%) were negative, and 32 positive NCS patients consisted of 9 positive (28.1%), 16 improved (50.0%), and 7 negative (21.9%) postoperatively. VAS score was 7.4 preoperatively and 4.4 postoperatively. According to satisfaction, there were 8 excellent (19.5%), 21 good (51.2%), 6 fair (14.6%), and 6 poor (14.6%) patients. For 32 patients who were positive on the preoperative NCS, the postoperative VAS score was 4.87 and there were 7 excellent (21.9%), 16 good (50.0%), 4 fair (12.5%), and 5 poor (15.6%) patients. Sixteen patients were negative on the postoperative NCS, with a VAS score of 3.75, 1 excellent (6.3%), 11 good (68.8%), 2 fair (12.5%), and 2 poor (12.5%). There was no statistical correlation between the preoperative NCS and postoperative VAS score (p=0.10), between preoperative NCS and postoperative satisfaction (p=0.799), between preoperative NCS and postoperative VAS score (p=0.487), and between postoperative NCS and postoperative satisfaction (p=0.251). Conclusion: For patients diagnosed with tarsal tunnel syndrome and treated surgically, NCS showed little correlation with postoperative result.

Calcaneus is largest tarsal bone and the fracture of calcaneus is most common tarsal fractures. Calcaneal fractures are divided into extra-articular and intra-articular fractures. Intra-articular calcaneal fractures could be classified as tongue type and joint depression type using simple lateral radiograph (Essex-Lopresti classification), but Sanders suggested new classification according to involving the posterior facet of calcaneus using computed tomography. The involvement of posterior facet was revealed as more complicated than Essex-Lopresti classification. The principle purpose of treatment of calcaneal fractures are restoration of calcaneal height (B$\ddot{o}$hler angle), width, axis, anatomical reduction of joint and restoration of function through the stable fixation. Good visualization of joint and anatomical reduction could be achieved by extended lateral approach. But, skin problem could be occurred after of extended lateral approach.

Tarsal coalition is an abnormal union between two or more bones of the hind- and mid-feet, which can occur at various rates from cartilaginous to osseous union. Talonavicular coalition is reported less frequently than calcaneonavicular or talocalcaneal coalition and has been associated with various abnormalities, including symphalangism, clinodactyly, ray anomaly, clubfoot, other tarsal coalitions, and a ball-and-socket ankle joint. Patients with talonavicular coalitions are usually asymptomatic and rarely require surgical treatment. We review the literature and report on a case of 59-year-old male patient with talonavicular coalition.

Purpose : To describes the important aspects of the foot and ankle movement and function used when git and balance strategy. Method : The foot and ankle was a very important roles in the lower limb movement and gait. This study summarizes the physiologic movement of knee to the PNF lower extremity patterns. Result : The ankle joint composed of the talocural joint, the subtalarl joint, transverse tarsal joint, talocalcaneonavicular joint. The onset of dorsiflexion muscle activity starts in pre swing gait patterns. First contract muscle is the extensor hallucis. Activity of tibialis anterior and extensor digitorum longus quickly follows in mid swing gait phase. During stance phase, the soleus and gastrocnemius muscle provided plantar flexor torque, which muscle reacts quickly to restrain ankle dorsiflexion, and contributes modulated control of the ankle motion in gait patterns. Conclusions : The understanding of ankle kinematics, could provide a good therapeutic approach for improving gait patterns in patients with various pathological condition.

Purpose: This study was designed to analyze the usefulness of Single Photon Emission Computed Tomography/Computed Tomography (SPECT/CT) in diagnosing symptomatic accessory tarsal bones. Materials and Methods: Twenty four feet (16 patients) with symptomatic accessory navicular and/or os trigonum, who agreed to take SPECT/CT, were included in this study. Fifteen feet had accessory navicular, five had os trigonum, and four had both. According to the uptake in the SPECT/CT, 11 feet were classified into high and 13 into low uptake groups. The low uptake group was treated non-operatively, while the high uptake group received operations when initial conservative management failed. A modified Kidner procedure was performed for accessory navicular and arthroscopic excision was done for os trigonum. After a mean follow-up of 6.8 (range, 3~13) months, the American Orthopaedic Foot and Ankle Society (AOFAS) score and the Visual Analogue Scale (VAS) for pain were compared. Results: Patients in the high uptake group had a higher initial mean VAS score ($7.0{\pm}0.8$ vs $2.2{\pm}0.9$, p<0.05) and a lower initial mean AOFAS score ($45.9{\pm}9.2$ vs $83.9{\pm}4.2$, p<0.05) compared to the low uptake group. All patients in the low uptake group improved after non-operative treatment. Seven patients underwent operations and had a decreased VAS ($1.6{\pm}0.5$) and an increased AOFAS score ($88.3{\pm}1.8$) at the last follow-up. Four patients in the high uptake group demonstrated erratic symptoms. Conclusion: SPECT/CT can be a useful diagnostic tool and helpful in designing treatment plans for symptomatic accessory navicular and os trigonum.

The mare had lameness and asymmetry edematous on its tarsal and metatarsal joints at the initial physical examination. The pain was elicited with a palpation along the metatarsal articulations. No significant abnormalities were detected in the screening test. However, thermographic images revealed a significant increase in the surface temperature at the joint of the hindlimb when compared to the reference range. At necropsy, an irregularity of the surface and excessive synovial fluid were observed on the right tarsal joint. No bacterial growth was shown in the cultures of synovial fluid. Staphylococcus aureus was detected in the subcutaneous discharge. Taken together, the thermography images were very useful in localizing the area of injury and were an effective diagnostic methodology for assessing lameness.

Background: Tarsal tunnel syndrome (TTS) is an entrapment neuropathy of the tibial nerve within fibrous tunnel on the medial side of the ankle. The most common cause of TTS is idiopathic. This is a retrospective study to define the electrophysiological characteristics of idiopathic TTS. Methods: We reviewed the medical and electrophysiological records of consecutive patients with foot sensory symptoms referred to electromyography laboratory. Inclusion of patients was based on clinical findings suggestive of TTS. Among them, patients with any other possible causes of sensory symptoms on the foot were excluded. Control data were obtained from 19 age-matched people with no sensory symptoms or signs. Routine motor and sensory nerve conduction study (NCS) including medial plantar nerve (MPN) using surface electrodes were performed. Result: Twenty one patients (13 women, 8 men, 9 unilateral, 12 bilateral) were enrolled to have idiopathic TTS (total 31 feet). Tinel's sign was positive in 16 feet (51.6%) of TTS and four feet (10.5%) in control group. The statistically significant electrophysiological parameter was difference of sensory conduction velocity (SCV) between sural nerve and MPN. Amplitude of sensory nerve action potential and SCV of MPN were not different significantly between idiopathic TTS feet and controls. Conclusion: Bilateral development in idiopathic TTS was more common. Tinel's sign and difference of SCV between sural nerve and MPN may be helpful for the diagnosis of idiopathic TTS.

The tarsus in dogs has a complex structure that makes its evaluation relatively challenging. Because an accurate diagnosis of the tarsus is difficult through basic examinations alone, imaging tests are essential. Previous studies have explored the anatomical and radiological features of the canine tarsus using several imaging modalities. However, the imaging utility of the tarsus across different modalities has not been thoroughly evaluated. This study aimed to visualize the tarsal structures using magnetic resonance imaging (MRI) and ultrasonography, compare their utility, and propose suitable imaging modalities and conditions for evaluating specific tarsal structures. Magnetic resonance imaging and ultrasound scans of the tarsus of four healthy dogs were performed, and two observers rated the utility of each image on a five-point scale. Although MRI is more beneficial for assessing the tarsal structures than ultrasound, ultrasound also appears clinically useful for evaluating the cranial tibialis muscle, deep digital flexor tendon, subcutaneous fat, joint space, and superficial digital flexor tendon. In addition, each structure of interest can be evaluated for optimal visibility using specific ultrasound sections, MRI sequences, and planes. In veterinary clinical practice, an initial assessment using ultrasound imaging with optimal visibility is required and if further evaluation is necessary, MRI examinations with optimal MRI sequences and planes can be performed.
