Biomechanical evaluation and comparison of polyetheretherketone rod system to traditional titanium rod fixation on adjacent levels
Conclusion In comparison with rigid fixation, some potential advantages of using PEEK rod systems include a reduced stress on adjacent segment disc and facet joint, and the elastic ability of PEEK rod fixation allows for a greater range of motion, which may reduce the incidence of clinical complications seen with rigid fusion devices.

Deformities of proximal femur in spastic hip displacement: A reconstructed three-dimensional computed tomography model approach
Conclusion Using reconstructed 3D-CT images we can directly measure and prove these femoral deformities. We found that AI has a positive correlation with MP (0.69), which is consistent with the results of previous studies. The displaced side has greater femur anteversion (42.7° vs. 36.3°), and coxa valga is common in these nonambulatory patients, irrespective of whether or not these patients underwent hip displacement. In addition, the severity of AI and anteversion angle will be affected by the MP. (Source: Formosan Journal of Musculoskeletal Disorders)

Transsacral transvertebral screw fixation and posterolateral fusion for spondyloptosis in an adolescent
Publication date: August 2013 Source:Formosan Journal of Musculoskeletal Disorders, Volume 4, Issue 3 Author(s): Chien-Fu Chen , Chih-Ming Wu , Fang-Ying Wang , Kao-Wha Chang Spondyloptosis is a condition in which the L5 vertebral body dislocates completely from the sacrum anteriorly and descends into the pelvis. Surgical options include posterior and anterior fusion, single- or two-stage operation, and neural decompression. We performed a one-stage operation on an adolescent with spondyloptosis by using an L2–S1 ilium posterior fusion with pedicle screws, cement augmentation, transsacral transvertebral screw fix...

The clinical significance of rapid prototyping technique in complex spinal deformity surgery—Case sharing and literature review
In this study, we intend to share our experience with the RP technique in pediatric spine deformity cases and to provide a literature review. In our study, two patients with severe spinal deformity were included. A real-size spinal model was produced for each patient on the basis of contiguous computer tomography with a slice thickness of 1 mm. All models were used to plan the resection and to identify the anatomic landmarks during the operation. With the aid of these full-scale spinal models, all surgical procedures were performed exactly according to the preoperative plan. A 16-year-old girl with congenital scoliosis wi...

Excision of high sacral giant cell tumor and reconstruction with bone cement
We report the case of a woman who had a right sacroiliac giant cell tumor with S1 nerve root involvement. No specific functional defects were noted after she underwent combined anterior abdominal and posterior sacral approaches for tumor excision and reconstruction with bone cement. Our goal is to determine whether or not, with carefully planned procedures and delicate nerve protection, the biomechanical stability of the sacrum was affected after the tumor resection. We believe that bone cement impaction can be considered as an alternative reconstructive method instead of high-priced, complicated fixation devices or allogr...

Triple injury to the superior shoulder suspensory complex
We report a 44-year-old man who suffered such an injury involving fractures of the coracoid process and acromion combined with dislocation of the acromioclavicular joint. This patient then underwent surgical intervention via open reduction and internal fixation. After 6 months of follow-up, radiographs revealed proper reduction and alignment of the scapuloclavicular connection. The patient was asymptomatic; he could move his shoulder freely and achieve a full range of motion. Triple injury to this structure definitely warrants surgical intervention. As presented, reduction and fixation aimed at reconstruction and restorati...

Irreducible dislocation of the knee joint
This article presents an unusual case of irreducible knee dislocation, in which the medial femoral condyle buttonholed through the medial retinaculum and capsular structure. Closed reduction attempt was unsuccessful. Open joint reduction was performed. Direct repair of the medial collateral ligament and retinaculum, and arthroscopic assisted posterior cruciate ligament reconstruction were also performed. Arthroscopic-assisted anterior cruciate ligament reconstruction was carried out in staged operation. (Source: Formosan Journal of Musculoskeletal Disorders)

Pulmonary embolism manifested as acute coronary syndrome after arthroscopic anterior cruciate ligament reconstruction
Publication date: August 2013 Source:Formosan Journal of Musculoskeletal Disorders, Volume 4, Issue 3 Author(s): Yueh-Ching Liu , Ting-Kuo Chang , Shih-Chia Liu , Yung-Chang Lu Pulmonary embolism (PE) is a rare but serious complication following orthopedic surgery. Routine prophylaxis remains a controversial issue. The current study outlines the case of a 34-year-old male patient with delayed diagnosis of PE 15 days after arthroscopic reconstruction of anterior cruciate ligament (ACL) without thromboprophylaxis. He was diagnosed with acute coronary syndrome initially, but the symptoms could not be relieved after ca...

Arthroscopic repair of Bankart lesion in traumatic anterior-inferior shoulder instability using the two-portal method: A preliminary report
Conclusion In patients with traumatic anterior glenohumeral instability, arthroscopic Bankart repair with the two portal method can provide good results. It can be an alternative method of treating patients with Bankart lesion without associated major glenoid defect or rotator cuff lesion in traumatic anterior-inferior instability.

Functional results of arthroscopic triangular fibrocartilage complex reconstruction in chronic distal radioulnar joint instability
Conclusions The results of this study suggest that arthroscopic TFCC reconstruction using the PL tendon is an effective method for treating chronic and irreparable TFCC tears with DRUJ instability. (Source: Formosan Journal of Musculoskeletal Disorders)

Acute shoulder infection following acupuncture—A report of three cases
We present three cases who developed severe infection following acupuncture, leading to irreversible osteoarthritic changes in their glenohumeral joints. All of them mentioned a history of acupuncture therapy before their shoulder became swollen and hot and no other infection source could be detected. Possible explanations included: (1) breakdown of the sterile technique; (2) no consensus of acupoint or how deep the needle should be inserted; (3) patient’s comorbidities, such as diabetes mellitus or previous shoulder pathology, were not considered. Although these three patients underwent debridement and proper management...

Locked posterior dislocation of the shoulder joint: Report of two cases
We report two cases of posterior dislocation of the shoulder joint that were missed initially at another hospital. The patients presented with painful disability of the shoulder joint. Posterior dislocation of the shoulder joint was suspected after physical examination. Anteroposterior radiography was unable to confirm the diagnosis because an abnormal posterior relationship of humeral head to glenoid fossa could not be clearly identified. An axillary view was unobtainable because of severe pain and the limited joint motion available. CT showed posterior dislocation of the humeral head. The bony defect of the humeral head ...
