Vascular complications following a femoral fracture are rare but can result in serious issues. Several case studies have reported pseudoaneurysms occurring after direct trauma or the insertion of a proximal femoral nail in the case of a proximal femoral fracture. The authors encountered an 85-year-old patient treated with retrograde intramedullary nail fixation for a distal femur fracture and suffered a decrease in the hemoglobin level, swelling, and pain on the 9^th day after surgery. The authors initially attributed the temporary hematoma and pain to ordinary postoperative processes. On the 16^th day after surgery, a pseudoaneurysm originating from the descending branch of the lateral femoral convolutional artery was diagnosed and treated by percutaneous vascular embolization. After the procedure, the hemoglobin level increased, and the swelling and pain decreased.

Purpose: To report our experience with nine cases of pathologic synovial plica on radiohumeral joint which symptom of painful snapping elbow was improved by arthroscopic resection. Materials and Methods: Between 1999 and 2004, 43 cases of elbow arthroscopy were performed by one surgeon. Eight patients with nine cases showed pathologic synovial plica in conjunction with snapping or posterolateral elbow pain. The mean age of eight patients (man: 7, woman: 1) was 29 years (range $16{\sim}56$ years). All patients had a trial of conservative treatment at least six months (range $6{\sim}16$ months). The diagnosis was confirmed before surgery in six cases and at the time of surgery in three cases. Pain, snapping, and subjective results were evaluated at least 12 months in the average(range $12{\sim}24$). Results: All patients showed a hypertropic lateral synovial plica with local synovitis. Seven of them had an associated lesion of chondromalacia on radial head. One of them was associated with radiocapitellar arthritis and had a wrapping over the radial head. Six patients experienced improved posterolateral pain at the end of study (VAS<1). However, the other two patients had occasional pain with activity. One of them persisted with mechanical symptoms, which was treated with additional arthroscopic procedure. Conclusion: Synovial plica in elbow should be considered as an important entity of common elbow disease, especially when pain in the lateral aspect of the elbow with a snapping sensation during motion is featured in patients. The arthroscopic resection seems to be safe and efficient in the short and long term treatment of plica in the elbow joint.

Purpose: To report two cases of bone tumors other than osteoid osteoma in the proximal femur and treated with percutaneous high frequency radioablation method. Cases: We reviewed two cases with intracortical chondroma and enchondroma in the femoral head retrospectively. The patient with intracortical chondroma was a thirty one year old woman and had suffered right hip pain of 1 year duration. The lesion was located in the head of right femur and treated with CT guided percutaneous high frequency radioablation after needle biopsy under general anesthesia. The symptom was gone immediately after the procedure and was discharged postop. 1 day. 15 months has passed without symptom recurrence. Second case having enchondroma, was 56 year old woman complaining of gluteal area pain for 3 months. Radiologic evaluation showed osteolytic lesion with sclerotic rim on the inferior portion of the left femoral head. She received a same therapy with CT guided radiofrequency ablation following needle biopsy. She reported dramatic pain relief after the procedure and was discharged postop. 1 day. No symptom has occurred for 3 months until now. Conclusion: We present 2 cases of bone tumor occurred in the hip joint area other than osteoid osteoma which were treated with CT guided radiofrequency ablation.

Purpose: The purpose of this study was to evaluate the results of limited vastus lateralis release for treatment of painful bipartite patella. Materials and Methods: From Jan. 1995 to Jun. 2002, we performed limited lateral retinacular release in 14 patients(16 cases) for treatment of painful bipartite patella. All patients were men and mean age was 22.3 years old. The opeative techique was that insertion of the vastus lateralis to the painful patellar fragment is detached subperiosteally. We evaluated the clinical results by degree of pain and level of activity. Also we analyzed the radiologic findings by measuring fragment tilting angle and gap between fragments. The mean follow up period was 14 months. Results: At final follow up, all of the patients showed pain relief and can be returned to more than recreational sports activity after the operation. On radiologic findings, fragment tilting angle and gap between fragments were reduced at statistically significant level. Conclusion: The limited lateral retinacular release for treatment of painful bipartite patella is one of good methods which is less invasive and shows good results in clinical and radiologic findings.

This study performed a proprioception improvement training for recurrence prevention of industrial workers with chronic lateral epicondylitis and analysed their pain and proprioception. The subjects of the study were thirty chronic lateral epicondylitis patients working for K company and were divided into elbow exercise program Group made of 15 subjects and proprioception improvement training Group made of 15. As variables for pain, pressure pain, and grip strength were measured and for the propioception, joint position sense of each group was measured before and after the exercise program. To compare differences before and after the program, a paired t-test was used and to compare differences between both groups, an independent samples t-test was used. As a result of the test, it was discovered that pressure pain, grip strength and joint position sense of the both groups were improved statistically significantly. These were statistically differential effect between each group on pressure pain, grip strength and joint position sense. In conclusion, it is suggested that proprioception improvement training should be considered as a method chronic and recurrence prevention lateral epicondylitis of industrial workers.

Purpose: We want to report on one patient who presented with lateral forearm pain caused by compression neuropathy of the lateral antebrachial cutaneous nerve. Materials and Methods: A female patient was managed by operative treatment (biceps tenoplasty) after failure with conservative treatment for 6 weeks. One year later, we evaluated the clinical symptoms and biceps tendon problems such as supination weakness or rupture after the tenoplasty. Results: Her symptom completely subsided immediately at the first postoperative day and her recovery was uneventful. Supination weakness and rupture of the distal biceps tendon were not found after the operation. Conclusion: We have reported here on a case of successful management of lateral antebrachial cutaneous neuropathy by performing biceps tenoplasty, along with a review of the previously published articles.

Purpose: To evaluate the usefulness of minimally invasive arthroscopy-assisted plate removal of a laterally inserted periarticular distal femur plate used for the treatment of AO type-C distal femur fractures. Materials and Methods: From October 2002 to November 2005, we evaluated 17 patients whose plates were removed through minimally invasive arthroscopy-assisted plate-removal technique and 15 patients who got their plates removed through conventional method without using arthroscopy, 32 patients in total. All these patients included in this study initially underwent open reduction and internal fixation of the distal femoral fractures with a lateral plate, and complained of continued pain over the lateral femoral condyle after the fracture fixation. The average age was 42.6 (ranges: 20~66) and initial fracture types included 16 cases of C1, 11 cases of C2, and 5 cases of C3 following AO/ASIF classification guidelines. Measured outcomes included: associated intra-articular pathologies, time needed to return to activities of daily living, patients' overall satisfaction, complications following the removal of hardware, and pain before and 6 months after the operation. Results: The distal-most end of the plate was placed in the knee joint in all cases and damage of the lateral articular capsule was found in 23 cases. Continuous wound discharge after surgery was found in one case who underwent arthroscopy-assisted plate removal, and it was treated by irrigation and re-suture. Average time needed to return to activities of daily living was 7 days in arthroscopy assisted group and 7.6 days in conventionally removed group. Fourteen patients (82.4%) who underwent arthroscopyassisted plate-removal reported above 'fair' satisfaction and the Visual analog scale pain score decreased from 4.9 to 1.9, six months after the plate removal. Thirteen patients(86.7%) who underwent conventional plate removal reported above 'fair' satisfaction and the Visual analog scale pain score decreased from 5.2 to 2.5, six months after the operation. Conclusion: Through minimally invasive arthroscopic-assisted plate removal, intrarticular pathology of the knee joint was able to be simultaneously identified and treated at the time of hardware removal. Damage of lateral capsule of the knee joint caused by the inserted plate for the treatment of type C distal femoral fracture was very frequently found and following the plate removal, patients experienced an improvement in pain score. We therefore recommend routine lateral distal femoral plate removal if the bony union is attained in such cases as type C distal femoral fractures whose distal most end of the plates are located in the joint.

The clinical results of 10 consecutive total ear canal ablation combined with lateral bulla osteotomy (TECA-LBO) in six dogs with chronic otitis externa and media were evaluated by the postoperative recovery and long-term follow-up. All dogs were selected for TECA-LBO on the basis of following five clinical symptoms. First, medical treatment couldnt improve clinical signs at least for eve. 2 months. Second, tympanic membrane was completely disappeared. Third, radiopacity was increased in tympanic cavity. Forth, petrous temporal bone was sclerosed. Fifth, ear canal calcification was progressed. And all cases were satisfied all five clinical symptoms. At 14. days after operation, the preoperative symptoms of chronic otitis externa and media which were scratching ear, pain, and hardening ear canal were resolved, and postoperative swelling, erythema, head tilt, and exudate from Penrose drainage were not existed In all cases. Loss of eye blink was happened in 4 cases, but these were disappeared between 14 days a(ter operation except one case on 3 months. All dogs were discharged form hospital at 14 days after operation. Between 3.5 and 6.5 months after discharging from hospital, para-aural abscessation was happened only in all Cocker spaniels. But this complication was solved by ventral bulla osteotomy (VBO). The dogs which didn't show para-aural abscessation after TECA-LBO didn't show scratching, pain, hardening of ear and hearing ability was improved, at 7.5 months after TECA-LBO. And the dogs which showed para-aural abscessation after TECA-LBO also didn't show scratching, pain, hardening of ear and hearing ability was also improved, at 7.5 months after VBO. In conclusion, After TECA-LBO, all dogs were recovered well without complication within 2 weeks except Cocker spaniel. And loss of eye blink can be cured naturally within 2 weeks after surgery. And para-aural abscessation can be happened between 4 and 7 months after TECA-LBO, so surgeon must follow-up until 8 months.

Purpose: The purpose of this study was to retrospectively evaluate the effect of 'Blocking Kirschner Wire (K-Wire) Technique', which has been developed to reduce protrusion of the lateral wall, in maintaining the level of reduction through clinical and radiological outcomes. Materials and Methods: Twenty-two patients with displaced intra-articular calcaneal fractures who used the blocking K-wire to maintain reduction (group A) and 44 patients that did not use blocking K-wire and were paired in 1:2 ratio with those Group A patients (group B), between January 2015 and December 2017 were enrolled in the study. All surgical procedures were performed via the extended sinus tarsi approach, and internal fixation using cannulated screws, Steinmann pins and K-wires was performed. American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale and postoperative recovery of exercise ability were compared for postoperative clinical outcomes. The radiological results were compared the Böhler angle, Gissane angle, calcaneal height and width, step off of posterior calcaneal joint, and the degree of protrusion of the lateral wall. Moreover, postoperative complications in both groups were compared. Results: There were no significant differences in the clinical outcomes of the two groups (p=0.924, p=0.961). The amount of Böhler angle, Gissane angle, calcaneal height and width, and step off of posterior calcaneal joint from the radiological results was not significantly different between the two groups (p=0.170, p=0.441, p=0.230, p=0.266, and p=0.400). However, the degree of protrusion of the lateral wall was 1.78 mm and 4.95 mm in group A and group B, respectively, and the difference between the two groups was significant (p=0.017). Although sural nerve entrapment and painful exostosis were more frequent in group B, they were occurred in a non-significant manner (p=0.293, p=0.655). Conclusion: Most of the clinical and radiological results as well as the complications were not significantly different between the two groups. However, the degree of protrusion of the calcaneus lateral wall in group A was promising. The 'Blocking K-Wires Technique' established by the authors may be an effective surgical option for maintaining the reduction of the lateral wall protrusion in displaced intraarticular calcaneal fractures.
