ABSTRACT
BACKGROUND: Greater tuberosity of humerus, as the attachment point of rotator cuff, plays a vital role in shoulder.Neer and AO classification for proximal humeral fractures have been accepted extensively. However, the classification for single greater tuberosity fractures of the proximal humerus is little reported, and its fixation method remains controversial.OBJECTIVE: To explore the curative efficacy of the double-row suture anchors under arthroscopy for avulsion-type greater tuberosity fractures (Mutch type Ⅰ) METHODS: Clinical data of 24 patients with avulsion-type greater tuberosity fractures (Mutch type Ⅰ) undergoing double-row suture anchors under arthroscopy were analyzed retrospectively. The displacement distance of the greater tuberosity of humerus was measured on CT before and after fixation. The shoulder joint was evaluated by Constant-Murley Score and the University of California, Los Angeles score at baseline, 1, 3, 6 and 12 months postoperatively. Besides, the visual analogue scale scores were detected at baseline and 12 months postoperatively.RESULTS AND CONCLUSION: (1) Double-row suture anchors effectively improved the displacement of greater tuberosity and rotator cuff injury. (2) The patients accompanied by rotator cuff injury accounted for 79.16%. (3) The Constant-Murley Score and the University of California, Los Angeles scores were significantly improved at each time point (P < 0.05). The visual analogue scale scores after fixation were significantly superior to those before fixation (P < 0.05). (4) These results suggest that the double-row suture anchors under arthroscopy can effectively improve the displacement of greater tuberosity and alleviate the pain. Moreover, it is conductive for early recovery of the shoulder function with little trauma, so it is a good choice for avulsion-type greater tuberosity fractures (Mutch type Ⅰ).
ABSTRACT
BACKGROUND:Anterior cruciate ligament (ACL) injury is a commonly sport-induced knee joint injury that does serious harm to the knee stability. ACL reconstruction is a commonly used treatment method, but researches on 1/2 peroneus longus tendon (PLT) graft are rarely reported. OBJECTIVE: To investigate the clinical outcomes of removing the autologous ipsilateral 1/2 PLT under arthroscopy for ACL reconstruction. METHODS:106 patients with complete ACL rupture in the Affiliated Hospital of Traditional Chinese Medicine, Southwest Medical University from December 2010 to December 2014 were enrolled, and autologous ipsilateral 1/2 PLT was removed under arthroscopy for ACL reconstruction. At baseline, 3, 6 and 12 months postoperatively, the knee stability was evaluated manually through the anterior drawer test, Lachman test, and pivot-shift test, and the knee function was evaluated by Tegner activity scale, Lysholm and International Knee Documentation Committee scores. RESULTS AND CONCLUSION: Postoperative anterior drawer test, Lachman test, and pivot-shift test tests were negative in all patients. In terms of Tegner activity scale, Lysholm and International Knee Documentation Committee scores, there were significant differences at baseline and postoperative 3 months as compared with postoperative 6 months (P 0.05). These results indicate that autologous ipsilateral 1/2 PLT is a good choice for ACL reconstruction under arthroscopy, achieving rapid and satisfactory functional recovery of the knee joint, which is not only minimally invasive and easy to operate, but also exhibits good therapeutic efficacy.
