Bone-grafting procedures are common in orthopedic trauma surgeries. There are only few reports on the morbidity after proximal tibia harvesting. Here, we report an experience of complication after proximal tibia harvesting while treating subtrochanteric femoral osteomyelitis.

A making appropriate portals is most important start in the arthroscopic surgery, and a step which determines the easiness of the operation procedures. It affects the precision of the examination of the target joints, making the next portals, and handling the instrument in the joint space. The knowledge about the normal and pathologic structures and understanding the portals should be needed to make an arthroscopic surgery ease.

Psoas compartment block has been used to provide anesthesia for orthopedic surgical procedures and postoperative pain control. Nowadays this block is advocated for the management of pain in the thighs, legs and lumbar area for various reasons. To relieve pain in the thigh and leg, 21 times of block were performed and observed clinically in the 17 patients at our hospital. The results were excellent for the relief of pain in metastatic cancer patients. And this block is satisfactory in the thigh pain but not in the leg pain. So we recommend psoas compartment block as a useful and simple method for the relief of pain in metastatic cancer pain in the thigh.

Authors introduce a case of successful orthopedic surgery for humeral fracture of Common buzzard (Buteo buteo). The bird, juvenile male, was rescued due to illegal gun shot in Yeoncheon-Gun, Kyonggi-Do. The external skeletal fixation (ESF) with intramedullary pinning (Tie-in method) using Imex clamps was chosen for this fracture case. The common buzzard was anesthetized with hand made face mask and Isoflurane. In particular, the rescued bird was needed rehabilitating procedures, such as flight training or physical exercise for their survivals in wild habitats. The injured buzzard is successfully recovered without any damage to ligaments and nerves after 6 weeks.

A psoas compartment block has been used to provide anesthesia for orthopedic surgical procedures and analgesia for post-operative pain. Currently, this block is advocated for relieving pain in the lower extremity and pelvic area resulting from various origins. We report a case of a 69-year-old male patient who had gait abnormality with posterior pelvic and hip pain, which were both aggravated by hip extension. From the magnetic resonance image, the patient was found to have a laterally herniated intervertebral disc at the L2/3 level, which compressed the right psoas muscle. This was thought to be the origin of the pain, so a psoas compartment block was performed using 0.25% chirocaine with triamcinolone 5mg, and the pain in both the pelvis and hip were relieved.

Indications of reverse total shoulder arthroplasty (RTSA) have been consistently extended by technical advancements in reverse arthroplasty prosthesis, continuous development of the implants, accumulated experiences and its successful treatment outcomes; accordingly, its use has rapidly increased. RTSA has been performed for a variety of indications, with variable outcomes depending on the initial diagnosis. However, controversial opinions still exist regarding the design of reverse arthroplasty prosthesis (medialized or lateralized design and the neck-shaft angle of the humeral prosthesis), suture of the subscapularis tendon, use of cement during placement of the humeral prosthesis, and surgical procedures; therefore, these should be investigated so that they can be better understood.

Corticotomy was introduced as a surgical procedure to shorten orthodontic treatment time. Corticotomy removes the cortical bone that strongly resists orthodontic force in the jaw and keeps the marrow bone to maintain blood circulation and continuity of bone tissues to reduce risk of necrosis and facilitate tooth movement. In the 21st century, the concept of regional acceleratory phenomenon was introduced and the development of the skeletal anchorage system using screw and plate enabled application of orthopedic force beyond conventional orthodontic force, so corticotomy has been applied to more cases. Also, various modified methods of minimally invasive techniques have been introduced to reduce the patient's discomfort due to surgical intervention and complications after surgery. We will review the history of corticotomy, its mechanism of action, and various modified procedures and indications.

Post-traumatic soft tissue defects sometimes require sequential flap coverage to achieve complete healing. In the era of propeller flaps, which were developed to reduce donor site morbidity, Feng et al. introduced the concept of the free-style puzzle flap, in which a previously harvested flap becomes its own donor site by recycling the perforator. However, when a perforator cannot be found with a Doppler device, we suggest performing a new type of flap, the flip-flap puzzle flap, which combines two concepts: the free-style puzzle flap and the flip-flap flap described by Voche et al. in the 1990s. We present the cases of three patients who achieved complete healing through this procedure.

Rotator cuff tear is often cited as a reason for shoulder pain and dysfunction in patients > 40 years of age. Surgical repair of rotator cuff tear is one of the most commonly performed orthopedic surgical procedures. Until now, the success rate of surgical repair for rotator cuff tear has not been satisfactory. Many factors influence the process of rotator cuff repair such as the presence of tendinosis and fatty infiltration, but the main factor is the difficulty in achieving healing at the tendon to bone interface. There is a clinical need for bioengineering approaches to promote regeneration of the native enthesis and reduce the poor outcomes after surgical repair. Toward this end, the design and fabrication of multiphasic or hierarchically structured scaffolds have received great attention. This manuscript deals with information on the tendon to bone interface and tries to find out why a multiphasic scaffold is necessary to reproduce it and considerations that need to be taken into to make an ideal scaffold.

Purpose: The purpose of this study was to evaluate the effect of Sodium hyaluronate-Sodium carboxymethyl cellulose (HA-CMC) on tissue adhesion after tenorrhapy in tenotomized Achilles tendon of the Sprague-Dawley rat. Materials and Methods: Twenty-eight legs of 14 Sprague-Dawley rat were used in study. After tenotomy of the Achilles tendons, tenorrhaphies were performed. Simple tenorrhaphy without any other procedures were performed on the left Achilles tendons (control group), and additional HA-CMC injections were done prior to the tenorrhaphy on the right Achilles tendons (HA-CMC group). Gross and histological examinations were made to identify differences between the two groups, 1, 2, 6, 8, 10, 12 and 14 weeks respectively. Results: Distinct decrease in granulation tissues and adhesions were seen in the HA-CMC group during gross inspection at 6 and 8 week after the operation. On histological analysis of the HA-CMC group, although increased infiltrations of inflammation cells were observed during 1 week, less adhesion were seen at 6, 8 and 10 weeks after the operation. In HA-CMC group, superior healing processes were seen at 6, 8 and 10 weeks and less fibrotic changes, compared to control group, were seen at 2 and 6 weeks. Conclusion: Prevention of adjacent tissue adhesion was made possible through decrease in collagen deposition and fibrosis by injecting HA-CMC before tenorrhaphy of Achilles tendon. Also, histologically faster healing process of the collagen fibers within the Achilles tendon was observed.
