Objective To review the injury mechanism and the treatment progress of terrible triad of the elbow, and to analyze the direction of further research. Methods Related literature concerning terrible triad of the elbow was extensively reviewed and comprehensively analyzed. Results The main treatment of terrible triad of the elbow is operation. The ultimate goal of treatment is to reconstruct sufficient stability of the elbow. The treatment includes fixation of the coronoid by suture, screw or plate; fixation of radial head by screw and plate, partial or complete replacement of the radial head; fixation of lateral collateral ligament and the medial collateral ligament by bone suture or anchors and the application of the external fixator. These surgical treatments have their own indications and advantages, most get satisfactory results. Conclusion Generally, surgery is needed to maintain the stability of the elbow for patients of terrible triad elbow. However, medial ligament repair or not, the choice of approach, and mechanism of injury still need further study.
【Abstract】 Objective To review the progress in pathoanatomy, diagnosis, and treatment of posterolateral rotatory instability (PLRI) of the elbow. Methods Related literature concerning PLRI of the elbow was extensively reviewed, comprehensive analysis was done. Results The lateral collateral ligament complex (LCLC), radial head, capitellum, and coronoid process are important constraints to PLRI. Muscle groups that cross the lateral elbow are secondary constraints to PLRI. Clinical examination includes lateral pivot-shift test, lateral pivot-shift apprehension test, chair sign, active floor push-up sign, tabletop relocation test, and posterolateral rotatory drawer test. Radiology, arthroscopy, and ultrasound can help diagnosis of PLRI. Reconstruction of bony fixation or soft tissue fixation can be used for treatment of injured LCLC. Conclusion The primary constraints to PLRI is LCLC. Ultrasound imaging is accurate for identification and measurement of normal LCLC. Therefore, ultrasound may prove valuable in assessment of abnormal lateral ulnar collateral ligaments. Reconstruction of soft tissue fixation, which can avoid iatrogenic fracture, is a selective treatment method.

Objective To review the progress in the diagnosis and treatment of tarsal coal ition. Methods Recent l iterature concerning the diagnosis and treatment of tarsal coal ition was reviewed. Results Tarsal coal ition is a bridge between the tarsal bones of the foot. The most common types are talocalcaneal and calcaneonavicular coal itions. Calcaneonavicular coal itions can be diagnosed with an oblique radiograph of the hindfoot. Most talocalcaneal coal itions require computer tomography for diagnostic confirmation. Magnetic resonance imaging may be useful for diagnoses of cartilaginous andfibrous coal ition. Casting is the usual initial treatment for the symptomatic individual. For patients with treatment failure and no degenerative changes, resection of the coal ition can be performed with good results. Isolated subtalar fusion may be performed for patients with failure of talocalcaneal resections. For patients undergoing failure of subtalar fusions and calcaneonavicular resection, tri ple arthrodesis may be performed. During minimally invasive operation, operation indications should be strictly controlled. Conclusion The diagnosis method of tarsal coal ition is clear. The cl inical manifestation combined with imaging examination can improve the diagnosis rate. The surgical indication of tarsal coal ition remains controversial, the randomized prospective studies are still required.
Objective To review the progress in the treatment and research of massive rotator cuff tears. Methods Recent l iteratures about the treatment and research of massive rotator cuff tears were reviewed. Results Treatment options of massive rotator cuff tears include nonoperative treatment, debridement, direct repair, tendon transfer, and repair with various substitutes, but the outcome is unpredictable. Recently, many experimental studies on the treatment of massive rotator cuff tears, such as gene therapy, cell therapy, and tissue engineering techniques, can provide cl inicians with new treatment strategies. Conclusion The treatment of massive rotator cuff tears pose a distinct cl inical challenge for the orthopaedist, depending on the overall presentation. The effect of traditional operation method to repair massive rotator cuff tears is limited. The treatment and research of massive rotator cuff tears still need to be studied.

Biodegradable polymer materials with its unique biological properties become the new direction of the tracheal prosthesis research.
Objective To review the progress in the cl inical treatment of Kienbouml;ck’s disease. Methods Related l iterature concerning the treatment of Kienbouml;ck’s disease was reviewed, and comprehensive analysis was done. Results The treatment methods of Kienbouml;ck’s disease include non-surgical treatment and surgical treatment, which are primarily guided bythe anatomic factor and Lichtman stage. Non-surgical treatment methods should be selected in patients of children and at stage I. Surgical treatment methods include vascularized bone graft transfer into the cored-out lunate, radial shortening osteotomy, radial lateral wedge osteotomy, etc. All surgical treatment methods have advantages and disadvantages. Conclusion For the treatment of Kienbouml;ck’s disease, none of procedure is superior to another. In short, choosing different treatment strategies based on different patients can achieve the desired outcome.
