PHILOS plate fixation in osteoporotic proximal humerus fracture of old age is well-known for high complication rate, especially metal failure, providing various augmentation techniques, such as calcium phosphate cement, allogenous or autologous bone graft. We report a case of polymethyl methacrylate augmentation to provide appropriate reduction with a significant mechanical support. This can be a treatment option for displaced unstable osteoporotic proximal humerus fracture with marked bony defect.

A 6-month-old, weighing 2.8 kg, female, domestic short-haired cat presented with open fracture at right distal radius about a month ago. Based on radiological findings, hyperplasia at the right radioulna and left humerus was found. Results of the cytological examination were inflammatory reaction and reactive osteoblast. Distal radial ostectomy proceeded with necrotic bone debridement. Three weeks after operation, the radial bone lysis was seen on radiograph but clinical condition improved. Hyperplasia at the right radioulna and left humerus was dissolved. Two months after operation, she can use her both forelimbs despite right elbow have been diagnosed as arthrosclerosis because of periosteal reaction. Six months after operation, clinical symptoms of limbs were not detected. In this case, open fracture was treated through delayed surgical debridement procedure, therefore hematogenous osteomyelitis occurs at another forelimb. The longer a wound remains open, the more likely it is that infection will develop. The infection can occur to fracture bone and seed from hematogenous spread to another normal bone. In conclusion, when open fracture occurs, early antibiotic treatment and urgent surgical intervention are recommended.

The anatomical structure of the Skeleton of thoracic 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 thoracic limb of the Korean native goat was composed of scapula, humerus, radius, ulna, carpal bones, metacarpal bones, phalanges and sesamoid bones. 2. The scapula was flat and triangular in shape. There were no distinct tuber of spine and acromion in the spine. The subscapular fossa was deep and triangular in shape and the vertebral border was sigmoid form. The coracoid bone was formed as the coracoid process at the medial aspect of the supraglenoid tubercle but the clavicle wa.s not observed. The left and right scapular indexes were 57.92 and 58.31 and the glenoid cavity indexes were 89.23 and 86.82, respectively. 3. The greater tubercle of the humerus was devided into cranial and caudal parts. The third tubercle was observed and the face for the infraspinatus muscle was rectangular form. The left and right humerus indexes were 32.44 and 32.63, the head indexes were 94.13, 96.62 and the trochlear-epidondyle indexes were 67.32 and 65.81, respectively. 4. The radius and ulna were fused entirely except at the broad proximal and narrow distal interosseous spaces. The ulna was longer than the radius, and its reduced body and distal end were fused at the caudomedial surface of the radius. 5. The carpal bones were six in number. There were radial, intermediate, ulnar, accessory, second-third and fourth carpal hones in carpal bones. 6. The metacarpal bone was composed of a large metacarpal bone resulted from the fusion of the third and fourth metacarpal bones, and there was a metacarpal tubercle at the dorsolateral part of the proximal end. There were no vestiges of the second and fifth metacarpal bones. 7. The digits were composed of third and fourth digits and each digit was composed of the proximal, middle and distal phalanges. 8. The sesamoid bones were six in number. There were two at the fetlock joint and one at the coffine joint palmarly in each digit. 9. The ratios of the lengths among the scapula, humerus, antebrachium and metacarpal bone were 1.42 : 1.47 : 1.77 : 1.00 in the left and 1.42 : 1.45 : 1.77 : 1.00 in the right, respectively.

Fibrous dysplasia is a benign pathologic condition in which the normal cancellous bone is replaced by the fibro-osseous tissue. It is found mostly in the femur, tibia, skull, rib, and humerus. Clinically it may develops pain, progressive deformity, and pathologic fracture. Curettage with bone graft has been the most popular treatment method thesedays. A 17-year-old female who had fibrous dysplasia of the humerus combined with multiple cystic lesion was treated by intralesional steroid injection into the lesion total 2 times. The follow-up plain X-ray which was taken 11 months after steroid injection reveals decrease in size and increase in bone density and cortex thickness. The follow-up MRI reveals significant decrease in size and signal intensity. The signal intensity was decreased to that of normal bone marrow in T2 weighted image. She complains no pain and lives symptom free in last follow-up at 2 years and 8 months after steroid injection.

Purpose: To evaluate the results of the compression plate fixation and autogenous bone graft in the management of humerus shaft nonunion. Materials and Methods: Eighteen cases were treated for humerus shaft nonunion using compression plate fixation and an autogenous iliac bone graft. The mean follow-up period was 28 months. Bony union was confirmed from the serial radiographs and the clinical outcomes were assessed according to ASES scoring system. Results: In 12 cases of initial plate fixation, the causes of nonunion were 6 cases of inadequate plate length, 2 with a broken plate, 2 with screw loosening, 1 infection and 1 noncompliance of a psychiatric patient. In 3 cases of initial intramedullary fixation, the cause of nonunion was a distraction of the fracture site. In 3 cases of external fixation, the cause of nonunion was inadequate fixation. All cases showed bony union after an average of 24 weeks. The clinical outcomes were 11 excellent, 6 good and 1 fair. Conclusion: In the treatment for nonunion, compression plate fixation with autogeneous bone graft after complete removal of the fibrous and necrotic tissue is believed to give satisfactory results.

Purpose : The purpose of the current study is to evaluate the functional and oncologic results of the limb salvage surgery with intramedullary nailing and cementization in malignant bone tumors of the proximal humerus. Materials and Methods : We reviewed 18 cases of limb salvage surgery of resection and reconstruction with an intramedullary nail and cement-molded humeral head for the malignant bone tumors of the proximal humerus, which performed between August, 1992 through the April, 1998. The diagnoses included the osteosarcoma in 7 patients, chondrosarcoma in 3, the recurrent giant cell tumor in 3, metastatic tumor in 3, multiple myeloma in one patient and the one patient with malignant fibrous histiocytoma. The mean age at the time of surgery was 38 years(range, 15-73 years). The mean follow-up period was 26 months(range, 6-67 months). Results : Average functional score by ISOLS evaluation system was 21.1(70.3%). There were 3 local recurrences and 5 distant metastases. There were one case of shoulder instability and one case of deep infection. The seven patients are continuously disease free state and seven patients are alive with disease. Four patients died from the disease. Conclusion : The limb salvage surgery with intramedullary nailing and cementization in the bone tumors of the proximal humerus may be considered an option for the malignant bone tumors of the proximal humerus in selected patients.

To report the fracture of proximal humerus in the lateral anchor site after suture bridge repair. A 57-year-old female patient with shoulder pain on the right-side was admitted through the emergency room following a car accident. Seven weeks before the accident, the patient had undergone surgery at a different hospital for the repair of supraspinatus tendon rupture on the right-side via suture bridge technique. Humerus surgical neck fracture was confirmed by X-ray, and proximal humerus fracture at the anchor site was confirmed by magnetic resonance imaging. Following 7 months of conservative treatment resulted in satisfactory bone union and motion of the shoulder joint. We report the need of close observation during and after the arthroscopic repair of the rotator cuff in patients with osteoporosis.

Distal humerus fractures (DHFs) are challenging to treat due to the locally complex osseous and soft tissue anatomy. Adequate exposure of the articular surface of the distal humerus is crucial when performing an anatomical reconstruction of the elbow. Even though "triceps-on" approaches are gaining popularity, one of the most commonly used surgical treatments for DHF is olecranon osteotomy. The incidence of complications related to this approach is unclear. This review was performed to assess the type and frequency of complications that occur with the olecranon osteotomy approach in the treatment of DHF. A literature search was conducted in the PubMed/Medline, Embase, and Cochrane Library digital databases up to February 2020. Only English articles describing complications of olecranon osteotomy in the treatment of DHF were included. Data on patient and surgical characteristics and complications were extracted. Statistical analysis was performed using SPSS. A total of 41 articles describing 1,700 osteotomies were included, and a total of 447 complications were reported. Of these 447 complications, wound infections occurred in 4.2% of osteotomies, of which 1.4% were deep infections and 2.8% were superficial. Problems related with union occurred in 3.7% of osteotomies, 2% of which represented non-union and 1.7% delayed union. The high risk of complications in olecranon osteotomy must be considered in the decision to perform this procedure in the treatment of DHF.

Purpose: The purpose of this study is to evaluate the clinical and radiological outcomes of treatment of humerus shaft simple fracture by minimally invasive percutaneous osteosynthesis (MIPO) technique using locking compression plate (LCP). Materials and Methods: Six patients who were operated for humerus shaft simple fracture from August 2010 to May 2011 were enrolled for this study. We checked the cause of injury and the accompanying injuries and evaluated the operation time, the clinical and radiological period of union, postoperative range of motion of the shoulder and elbow joint, pain, activities in daily living, radiologic alignment, and other complications. Results: The clinical period of bone union was 7.2 weeks on average, and the radiologic period of bone union was 8 weeks on average. Follow-up period was more than 12 months in all cases. The angulation through postoperative alignment was 2.8 degrees in AP view and 2 degrees in lateral view. The postoperative range of motion was 167 degrees in forward flexion, 50 degrees in external rotation, and thoracic vertebra 12 level in internal rotation. The average value of visual analogue scale (VAS) was 1.2 and that of KSS was 91.3. The American Shoulder and Elbow Surgeons' score (ASES) was 26.5 and the UCLA score was 31.5. Conclusion: MIPO technique for the humerus shaft simple fracture showed good functional and radiological outcomes and may be considered as one of the treatment options for humerus shaft simple fracture.
