Comparison of surgical outcome between bursal and articular partial thickness rotator cuff tears.

Surgical outcomes after arthroscopic subacromial decompression and debridement in bursal and articular partial thickness rotator cuff tears with a tear depth of < 50% were compared. Twenty-four articular and 13 bursal partial thickness rotator cuff tears were evaluated for pain relief and functional recovery. At 6 months postoperatively, the average pain score decreased from 6.2 to 1.7 in patients with articular tears and from 7.1 to 0.9 in patients with bursal tears. Although pain relief and functional recovery were excellent in both groups, the results were better in patients with bursal partial thickness rotator cuff tears at 6 months postoperatively.

Surgical Treatment of Thoracic Outlet Syndrome Secondary to Clavicular Malunion

According to the literature, thoracic outlet syndrome (TOS) secondary to the malunion of displaced fractures of the clavicle is rare. Various surgical methods, including simple neurolysis, resection of the first rib or clavicle and corrective osteotomy, have been reported. We report a case of TOS secondary to malunion of the clavicle that was treated by an anterior and middle scalenectomy without a rib resection.

High Prevalence of Sarcopenia in Korean Patients after Hip Fracture: a Case-Control Study

Sarcopenia-related falls and fractures are increasing worldwide due to the aging population. The purpose of this study was to 1) evaluate anthropometric characteristics related to hip fracture in Korean patients, 2) investigate sarcopenia prevalence in hip fracture (HF) and non-hip fracture (NF) groups, and 3) investigate the correlation between sarcopenia and osteoporosis. This case-control study examined 359 HF and 1,614 NF normal populations using Korea National Health and Nutrition Examination Survey data. We performed whole-body dual energy X-ray absorptiometry to analyze body composition using the skeletal muscle mass index (SMI: lean mass/height2) and bone mineral density (BMD). In the HF group, using the AWGS definition, the prevalence of sarcopenia in women and men was 44.3% and 68.2%, respectively; in the NF group, it was 7.1% and 16.1%, respectively. Lower appendicular SMI (P < 0.001), leg muscle mass (P < 0.001), and higher prevalence of sarcopenia (P < 0.001) were observed in the HF group after adjustment for age and gender. In multivariate analysis, sarcopenia (OR = 6.52; 95% CI = 4.67-9.09), age (OR = 1.15; 95% CI = 1.13-1.17), and osteoporosis (OR = 1.87; 95% CI = 1.35-2.58) were associated with the occurrence of a hip fracture. This study showed a higher prevalence of sarcopenia in patients with hip fractures compared with a normal population, and higher prevalence of sarcopenia in men.

Osteochondroma Associated With Complete Rupture of the Distal Biceps Tendon: Case Report

Osteochondromas are the most common benign bone tumors. However, osteochondromas rarely involve the proximal radius. We present the case of a solitary osteochondroma that occurred in a critical area of the proximal radius near the insertion of the biceps tendon and ultimately led to rupture of the tendon. The lesion was confirmed histologically and resected, followed by successful repair of the distal biceps tendon using a suture anchor.

The Efficacy and Safety of Autologous Transfusion in Unilateral Total Knee Arthroplasty.

Purpose Although allogeneic blood transfusion is the most common method of transfusion in total knee arthroplasty (TKA), there are reports showing significant decrease in the amount of allogeneic transfusion and incidence of side effects after combined use of autologous transfusion. The purpose of this study is to investigate the efficacy of using an autologous transfusion device in TKA. Materials and Methods Patients who underwent TKA at our institution from January 2003 to January 2014 were divided into two groups: group A (n=127) who received allogeneic transfusion only in TKA and group B (n=118) who received autologous transfusion via an autologous transfusion device and allogeneic transfusion. In both groups, the patients were transfused when the hemoglobin level was below 9 g/dL. In group B, blood collected by the autologous transfusion device was transfused only once after surgery. The total blood loss volume, total transfusion volume, and the presence of side effects were assessed based on medical records. Results Group A received 294.6 mL more allogeneic transfusion than group B (p<0.001). There were no significant differences with regard to the development of side effects between groups. Conclusions Application of an autologous transfusion device during TKA can be effective in reducing the allogeneic transfusion volume. Moreover, allogeneic transfusion was not necessary after autologous transfusion in some patients.
