ABSTRACT
BACKGROUND: Metal anchors are not easily accepted by patients as permanent foreign bodies, so bioabsorbable anchors have been gradually applied in orthopedics in recent years. OBJECTIVE: To evaluate the effectiveness of absorbable suture anchors for repairing femoroacetabular impingement syndrome combined with acetabular labral tears. METHODS: Eighty patients with femoroacetabular impingement syndrome combined with acetabular labral tears admitted in Beijing Shijitan Hospital Affiliated to Capital Medical University from February 2014 to February 2016 were selected, and all were treated by absorbable suture anchors under arthroscopy. The Harris hip score, and the Visual Analogue Scale score at baseline, postoperative 1 and 3 months were recorded and compared to assess the effectiveness. The complications and material-host reaction were recorded. The treatment satisfaction was evaluated. The study was approved by the Ethical Committee of Beijing Shijitan Hospital and all patients and their families signed the informed consents. RESULTS AND CONCLUSION: (1) The Harris hip scores at 1 and 3 years postoperatively in 80 patients with femoroacetabular impingement syndrome combined with acetabular labral tears were significantly higher than those at baseline, and the Visual Analogue Scale scores were significantly lower than those at baseline (P 0. 05). (3) None appeared with anchor drop off, cartilage injury or material-host reaction. In summary, the method of absorbable suture anchors under arthroscopy has the advantages of minimal invasion, reliable fixation, simple operation, no metal implants, and significant clinical effect to treat femoroacetabular impingement syndrome combined with acetabular labral tears.
ABSTRACT
Objective To observe the treatment effect of internal fixation with absorbable suture anchors for calcaneal apophysitis (Sever's disease). Methods The clinical data of 34 Sever's disease patients having received internal fixation with absorbable suture anchors from January 2010 to August 2012 were analyzed retrospectively. Of the 34 patients, 28 were male and 6 were female, aged from 11 to 30 years old (mean 19 years old); 20 with unilateral lesions, 14 with bilateral lesions; 32 suffered inflammatory edema, and 2 with epiphyseal avulsion. All of the patients were diagnosed as suffering from Sever's disease by X-ray combined with clinical symptoms. The sclerotic bone was chiseled off, the attachment site of Achilles tendon was fixed with auxiliary sutures of anchors and then fixed to the bone surface. Different rehabilitation programs were adapted in different periods after operation. The operation time, the site of anchorage and perioperative complications were analyzed, and the therapeutic effects were evaluated by Arner-Lindholm standard. Results All patients were followed up for 2-24 months (mean 9 months). The average operation time for one side was 40.5 minutes. No iatrogenic injury to nerve, vascular or tendon occurred during surgical procedure. No wound infection or foreign-body reaction was found after operation. The therapeutic effects evaluated by Arner-Lindholm standard were excellent in 29 cases, good in 4 and bad in 1 case. Conclusion Absorbable suture anchoring fixation is a reasonable and effective method for the treatment of Sever's disease, and it allows early exercise training for recovery of ankle function. The postoperative functional recovery is found to be satisfactory.
