Full-thickness rotator cuff tears are relatively uncommon in the young adults. One of the pathogenesis of such tear is thought to be closely related to the specific trauma event. Favorable outcome is expected in young patient rotator cuff tears when it is diagnosed early following prompt surgical repair. However, early detection is sometimes difficult when the acute rotator cuff tear is combined with other injuries especially around the shoulder joints such as ipsilateral humerus fractures. Authors report an uncommon case of acute traumatic rotator cuff tear accompanied by the midhumerus shaft fracture in young adult.

iepicondylar fracture of the humerus is very rare in adults. To date, there have been limited evidence of this injury in the English literature. We report a case of a 65-year-old female with a biepicondylar fracture of the left distal humerus without dislocation. Open reduction and internal fixation with K-wires, cannulated screw, and suture anchor were performed. We obtained stability of the elbow and a satisfactory functional outcome. Because this type of injury is associated with varus and valgus instability, operative reduction and fixation are essential in order to gain stability and early recovery of normal function.

Enchondromas generally occur in the hand and uncommonly in the long bones. Because enchondromas are usually asymptomatic, most are discovered during diagnostic radiology for another disease. Here, we describe a case of enchondroma in the right humerus in a 79-year-old female patient with concomitant rotator cuff tear arthropathy. The patient was initially hospitalized for prolonged pain and pseudoparalysis of the right shoulder. The condition, which was histologically confirmed as an enchondroma in the proximal humerus, was treated with curettage and reverse total shoulder arthroplasty. In this case report, we present a rare case of an enchondroma with combined rotator cuff tear arthropathy.

In orthopedic trauma surgery, treatment of intraarticular distal humerus fractures is a challenge. With development of implants and biomechanical studies, surgical strategies with recommendations including preoperative computed tomography images, proper approaches and open reduction and internal fixation with dual plates have emerged. In addition, as an effort to provide stable fixation to permit early elbow motion, different methods of internal fixation, particularly plate configuration, have evolved. Using dual plates, either oriented parallel to each other or orthogonal, stable fixation has been achieved and satisfactory clinical outcomes have been reported. With rationales and advantages/disadvantages of each plate configuration, both techniques are selected according to surgeons' preference, and, in specific cases, one could be preferred over another. The key to successful fixation by either technique is obtaining anatomical reduction with restoration of two stable columns of the distal humerus.

Osteochondritis dissecans (OCD) is an idiopathic condition affecting the articular epiphysis. Initially described in the knee, this entity affects several other parts of the body such as the talar dome, tarsal navicular, and femoral capital epiphysis. Osteochondritis dissecans (OCD) of the elbow is typically located in the capitellum of the humerus in young teenagers. OCD of humeral trochlea is very rare, but can be occurred among young athletes. OCD developed medial trochlea was extremely rare, especially, without any other trauma. We present a patient, pitcher with OCD in the medial trochlea of the humerus who underwent arthroscopic debridement and microfracture.

Humeral hemimelia is a rare congenital anomaly characterized by deficiency of the humerus with relatively intact scapular. The holstein calf was healthy expecting the deformity of forelimb humerus. The examination of PCR and serum neutralizing test was carried about BVD, akabane virus, Ibaraki virus and Kasba virus in cattle. The results were all negative. Affected calf showed forelimb deformation. Other abnormalitis was not observed in brain, spinal cord, liver, kidney and other visceral organs. Amelia are very rare limb anomalies. We report on a Holstein calf with forelimb deficiencies. This case appears humeral anomalies with ulnar and radius aplasia in calf. The condition in these calves was considered the result of a recurrence of a genetic mutation affecting a putative hemimelia locus.

Treating distal humerus fractures, especially those involving intra-articular lesions, is complex and often technically demanding. Although there still exist many controversial issues, the goal of treatment is to establish anatomical stable fixation by restoring the two columns and the articular surface. Universally, a posterior midline incision is applied, and the approach varies according to the further management of the triceps or olecranon. Evidence supports dual plate fixation as the optimal fixation method, and debates regarding appropriate plating configuration are still ongoing. As multiple clinical studies comparing results of parallel and perpendicular plate fixation have shown no actual difference, it is important to place the plates according to the fracture configuration.

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.

Purpose: To evaluate the clinical and radiographic results of the treatment of a proximal humerus fracture with a locking compression plate(LCP). Materials and Methods: This study reviewed the results of 24 cases of a proximal humerus fracture treated with a LCP from January 2005 to April 2007, after a follow up of more than 12 months. There were 8 males and 16 females with a mean age of 68.9(33-90) years. The clinical results were evaluated using the Neer's evaluation criteria, and the radiographic results were evaluated using the bone union time and Paavoleinen method. Results: The mean time for bone union was 11.9 weeks. Using the Neer's functional evaluation, 21 cases of the 24 patients (87%) showed excellent or satisfactory results. Twenty two cases (91%) showed good results according to the Paavoleinen method. The complications encountered were metal failure (1 patient), AVN of the humeral head (1 patient) and joint stiffness (1 patient). Conclusion: The LCP demonstrated good results in the treatment of a proximal humerus fracture and has relatively fewer complications than other internal fixators.

Purpose: In this study we introduced minimal invasive plate osteosynthesis (MIPO) and analyzed clinical outcomes to determine the effectiveness of this intervention in proximal humerus fractures. Materials and Methods: We studied 27 patients including 16 cases with a 2-part fracture, 10 cases with a 3-part fracture, and 1 case with a 4-part fracture. Clinical outcomes were evaluated using UCLA score, KSS score and recovery of range of motion. Time to union and humerus neck-shaft angle change were estimated by radiologic assessment. The average follow up period was 19 months. Results: UCLA scores were "excellent" for 15 patients, "good" for 12 patients. The mean KSS score was 91.4 at final follow-up. The average shoulder range of motion was $167.2^{\circ}$ in forward elevation. Bone union occurred by 14.1 weeks postoperatively. Humerus neck-shaft angle recovery was "excellent" in 24 patients and "moderate" in 3 patients. There were no complications such as axillary nerve paralysis, deep infection, or subacromial impingement of the plate. Conclusion: MIPO for proximal humerus fractures is an effective procedure if performed with sufficient understanding of the anatomical structures. MIPO leads to minimized dissection of soft tissue, low complication rates and early recovery of range of motion.
