A humeral hemiarthroplasty with biologic resurfacing of the glenoid using an allo-Achilles tendon: two case reports

A hemiarthroplasty with biologic resurfacing of the glenoid is one procedure that can be performed in young patients where total shoulder arthroplasty may be difficult. The authors introduced two cases in which this procedure was performed. This approach is one treatment option for young glenoid humeral arthritis patients that addresses some of the shortcomings of an isolated hemiarthroplasty.

Relationship of the Shape of Subacromial Spur and Rotator Cuff Partial Thickness Tear

BACKGROUND: The present study was undertaken to evaluate the relationship between location of the rotator cuff tear and shape of the subacromial spur. METHODS: Totally, 80 consecutive patients who underwent arthroscopic repair for partial thickness rotator cuff tear were enrolled for the study. Bigliani's type of the acromion, type of subacromial spur, and location of partial thickness tear of the rotator cuff were evaluated using plain X-ray and magnetic resonance imaging. We then compared the groups of no spur with spur, and heel with traction spur. RESULTS: Of the 80 cases, 25 cases comprised the no spur group, and 55 cases comprised the spur group. There was a significant difference in type of tear (p=0.0004) between these two groups. Bursal side tears were significantly greater (odds ratio=6.000, p=0.0007) in the spur group. Subjects belonging to the spur group were further divided into heel (38 cases) and traction spur (17 cases). Comparing these two groups revealed significant differences only in the type of tear (p=0.0001). Furthermore, the heel spur had significantly greater bursal side tear (odds ratio=29.521, p=0.0005) as compared to traction spur. CONCLUSIONS: The heel spur is more associated to bursal side tear than the traction spur, whereas the traction spur associates greater to the articular side tear.

Etiology and Treatment of Revision Shoulder Arthroplasty / 대한정형외과학회잡지

The rapidly increasing rate of shoulder arthroplasty is certain to increase the number of revision arthroplasties because of parallel increases in complication numbers. It has been widely reported that the causes of revision shoulder arthroplasty include rotator cuff deficiency, instability, glenoid or humeral component loosening, implant failure, periprosthetic fracture, and infection. Revision arthroplasty can be technically challenging, and surgical options available for failed shoulder arthroplasty are limited, especially in patients with glenoid bone loss or an irreparable rotator cuff tear. Furthermore, the outcomes of revision arthroplasty are consistently inferior to those of primary arthroplasty. Accordingly, surgical decision making requires a good understanding of the etiology of failure. Here, we provide a review of indications of revision arthroplasty and of the surgical techniques used by failure etiology.

Arthroscopic Biceps Tenodesis: Soft Tissue versus Bone Fixation / 대한스포츠의학회지

The purpose of our study was to compare the clinical results between arthroscopic bone fixation on intertubercular groove using suture anchor and soft tissue fixation at the rotaor interval for biceps tenodesis when partial tear or instability of biceps tendon accompanied with rotator cuff tear. From January 2010 to January 2012, 34 cases who were performed biceps tenodesis for partial tear or instability were enrolled in our study. Mean follow-up period was 30.2 months. Bone fixation using suture anchor was performed in 18 cases, and soft tissue fixation was performed in 16 cases. Clinical result was evaluated by pain visual analogue scale (VAS), Speed test, Yergason test, muscle strength, and Constant score. Pain VAS of cases with soft tissue fixation was significantly higher than that of cases with bone fixation at 6 months and final follow-up. Positive results for the final follow-up Speed and Yergason test were checked in 4 cases (25%) with soft tissue fixation and 1 (5.6%) with bone fixation. The Popeye deformity was seen in 4 cases (25%) with soft tissue fixation and 2 (11%) with bone fixation. Constant score was improved 47 to 78 in cases with soft tissue fixation and 48 to 86 in cases with bone fixation. In patient with partial tear or instability of biceps tendon accompanied with rotator cuff tear, biceps tenodesis using soft tissue fixation showed worse result compared with bone fixation because of long duration of the pain. Therefore, when performing the biceps tenodesis, bone fixation will be recommended.

Bipolar Hemiarthroplasty for Hip Fractures in Patients Aged over 90 Years: The Factors Influencing the Postoperative Mortality

PURPOSE: We wanted to evaluate the factors that influence the one-year mortality rate after bipolar hemiarthroplasty in elderly patients over 90 years of age and who had hip fractures. MATERIALS AND METHODS: In this retrospective study, we enrolled 42 cases (29 females and 12 males) that were treated by bipolar hemiarthroplasty for hip fractures between April 1999 and April 2008. The mean age was 94 (range: 90~101) years. We compared such variables as age, gender, BMD (bone mineral density), the ASA (American Society of Anesthesiologists) score, the type of fracture, the operation time, the type of anesthesia, the length of the ICU (intensive care unit) care, the length of hospitalization, operative delay and the postoperative ambulatory capability between the one-year mortality group and the control group (alive over a minimum of 1-year), and we investigated the risk factors related to one-year mortality. RESULTS: The one-year mortality rate was 32%. There were significant relationships between the postoperative one-year mortality and the ASA score, the length of the ICU care, operative delay and the postoperative ambulatory capability. The one-year mortality rate in the trochanteric fracture group was significantly higher than that in the neck fracture group. However, there were no relationships between the one-year mortality and age, gender, BMD, the length of operation, the type of anesthesia and the length of the hospitalization. CONCLUSION: The preoperative ASA score was significantly higher in the one-year mortality group among the elderly patients over 90 years of age and who were treated with bipolar hemiarthroplasty for hip fractures. The length of the ICU care, operative delay and the postoperative ambulatory capability were significantly associated with one-year mortality, and so all of these should be considered as postoperative prognostic factors.

Free Fillet Flap of the Forearm Amputee for Coverage of the Contralateral below Elbow Amputee and Restoration of the Flexion of the Elbow

Free vascularized tissue transfer to preserve upper extremity amputation level is uncommon but very useful procedure. To cover the below-elbow amputee stump and restore the function of the elbow, we have used a free flap as a spare part concept from the contralateral hand which was so severely damaged that amputation was inevitable.
