Shoulder Quadruple Dislocation Fracture: Fracture of Glenoid Rim, Coracoid Process, Greater Tuberosity, Surgical Neck of Humerus Associated with Anterior Shoulder Dislocation: A Case Report

Shoulder joint dislocation has the most common incidence rate compare compared to other joints. It is reported that shoulder Shoulder dislocation couldmay be associated with glenoid rim, greater tuberosity of humerus and coracoid process fracture. There were have only been 2 cases of anterior shoulder dislocation simultaneously combined with simultaneous glenoid rim, coracoid process, and humerus greater tuberosity fracture worldwide and no report reports in Korea. We present a case of quadruple fracture (glenoid rim, coracoid process, greater tuberosity, surgical neck of humerus) associated with anterior shoulder dislocation and treated successfully by open reduction. In addition, with we provide the injury mechanism, diagnosis, treatment procedure and discussion.

What Is the Most Effective Eccentric Stretching Position in Lateral Elbow Tendinopathy?

BACKGROUND: A variety of treatment options suggest that the optimal treatment strategy for lateral elbow tendinopathy (LET) is not known, and further research is needed to discover the most effective treatment for LET. The purpose of the present study was to verify the most effective position of eccentric stretching for the extensor carpi radialis brevis (ECRB) in vivo using ultrasonic shear wave elastography. METHODS: A total of 20 healthy males participated in this study. Resting position was defined as 90° elbow flexion and neutral position of the forearm and wrist. Elongation of the ECRB was measured for four stretching maneuvers (forearm supination/pronation and wrist extension/flexion) at two elbow angles (90° flexion and full extension). The shear elastic modulus, used as the index of muscle elongation, was computed using ultrasonic shear wave elastography for the eight aforementioned stretching maneuverangle combinations. RESULTS: The shear elastic modulus was the highest in elbow extension, forearm pronation, and wrist flexion. The shear elastic moduli of wrist flexion with any forearm and elbow position were significantly higher than the resting position. There was no significant difference associated with elbow and forearm positions except for elbow extension, forearm pronation, and wrist flexion positions. CONCLUSIONS: This study determined that elbow extension, forearm pronation, and wrist flexion was the most effective eccentric stretching for the ECRB in vivo.

Atypical Bipolar Segmental Fracture of the Clavicle in an Adolescent: A Case Report

Clavicular fractures commonly occur in adults and children. The usual site of these fractures is the mid clavicle with lateral end and medial end clavicular fractures being less common. Bipolar segmental clavicular injuries involving medial and lateral ends are rare but almost always occur in adults. This paper reports a very rare case of segmental clavicular fracture involving the medial and lateral end in an adolescent caused by direct trauma. The surgical management of a segmental fracture clavicle in an adolescent is reported with a discussion of the relevant literature.

Effect of Surgical-Site, Multimodal Drug Injection on Pain and Stress Biomarkers in Patients Undergoing Plate Fixation for Clavicular Fractures

BACKGROUND: Surgical-site, multimodal drug injection has recently evolved to be a safe and useful method for multimodal pain management even in patients with musculoskeletal trauma. METHODS: Fifty consecutive patients who underwent plating for mid-shaft and distal clavicular fractures were included in the study. To evaluate whether surgical-site injections (SIs) have pain management benefits, the patients were divided into two groups (SI and no-SI groups). The injection was administered between the deep and superficial tissues prior to wound closure. The mixture of anesthetics consisted of epinephrine hydrochloride (HCL), morphine sulfate, ropivacaine HCL, and normal saline. The visual analogue scale (VAS) pain scores were measured at 6-hour intervals until postoperative hour (POH) 72; stress biomarkers (dehydroepiandrosterone sulfate [DHEA-S], insulin, and fibrinogen) were measured preoperatively and at POH 24, 48, and 72. In patients who wanted further pain control or had a VAS pain score of 7 points until POH 72, 75 mg of intravenous tramadol was administered, and the intravenous tramadol requirements were also recorded. Other medications were not used for pain management. RESULTS: The SI group showed significantly lower VAS pain scores until POH 24, except for POH 18. Tramadol requirement was significantly lower in the SI group until POH 24, except for POH 12 and 18. The mean DHEA-S level significantly decreased in the no-SI group (74.2 ± 47.0 µg/dL) at POH 72 compared to that in the SI group (110.1 ± 87.1 µg/dL; p = 0.046). There was no significant difference in the insulin and fibrinogen levels between the groups. The correlation values between all the biomarkers and VAS pain scores were not significantly different between the two groups (p > 0.05). CONCLUSIONS: After internal fixation of the clavicular fracture, the surgical-site, multimodal drug injection effectively relieved pain on the day of the surgery without any complications. Therefore, we believe that SI is a safe and effective method for pain management after internal fixation of a clavicular fracture.

Posterior Shoulder Instability in the Patients with Bilateral Congenital Absence of Long Head of Biceps Tendon: A Case Report

Rare cases of a congenital absence of the long head of the biceps tendon (LHBT) have been reported, and its incidence is unknown. In a literature review of the congenital absence of the LHBT, only 1 case was associated with posterior shoulder instability and severe posterior glenoid dysplasia. This paper reports the first case of a patient with a bilateral congenital absence of the LHBT with posterior shoulder instability without glenoid dysplasia or posterior glenoid tilt. The patient experienced a traffic accident while holding the gear stick with his right hand. After the accident, a posteroinferior labral tear with paralabral cysts was detected on the magnetic resonance images. The congenital absence of the LHBT was assumed to have affected the posterior instability that possibly increased the susceptibility to a subsequent traumatic posterior inferior labral tear. This case was identified as a posterior inferior tear caused by a traumatic ‘gear stick injury’.

Correlation between Results of Preoperative Impingement Test and Clinical Outcomes after Arthroscopic Rotator Cuff Repair

BACKGROUND: The aim of the present study was to determine the correlation between the amount of pain reduction after local anesthetic injection into the subacromial space preoperatively and clinical outcome after arthroscopic rotator cuff repair. METHODS: A total of 127 patients who underwent arthroscopic rotator cuff repair and followed up at least 1 year were analyzed retrospectively. Preoperatively, a visual analogue scale (VAS) for pain was measured in all patients before and after the ultrasound guided impingement test. The participants were divied into four groups according to pain reduntion ater impingement test (Group A: >75%, Group B: 50%–75%, Group C: 25%–50%, Group D: <25%). VAS for pain, shoulder range of motion, shoulder isometric strength, ASES score were evaluated preoperatively and at 3, 6, 9, and 12 months postoperatively. RESULTS: After surgery, the amount of pain reduction shows significantly at 3, 6 months in Groups A, B as compared to Groups C, D (p<0.05). Among the range of motion of shoulder joint, forward flexion was significantly improved in Group A at 3 months (p<0.05). The ASES score significantly improved at 3, 6 months in Groups A, B as compared to Group C, D (p<0.05). CONCLUSIONS: Preoperative degree of pain reduction after impingement test correlates with the improvement of pain after arthroscopic rotator cuff repair, especially in the early phase. Therefore, the impingement test could be effectively used.

Efficacy and Safety of Combined Subacromial and Intravenous Patient-controlled Analgesia after Arthroscopic Rotator Cuff Repair

BACKGROUND: This study investigated the efficacy and safety of combined subacromial and intravenous patient-controlled analgesia for control of postoperative pain after arthroscopic rotator cuff repair. METHODS: Between May 2012 and August 2014, 60 patients who underwent arthroscopic rotator cuff repair with acromioplasty and received patient-controlled analgesia were studied prospectively. Cases were divided into 2 groups: combined subacromial and intravenous infusion group (group A, 30 cases) and solitary intravenous infusion group (group B, 30 cases). The visual analogue scale was used to record the patient's level of pain every 12 hours during postoperative 72 hours and the following 48 hours after the suspension of patient-controlled analgesia. RESULTS: The mean preoperative visual analogue scale score was 7.8 in group A and 7.6 in group B, and the immediate postoperative visual analogue scale score was 7.9 and 8.1 for each group. At postoperative time (From 12 hours to 72 hours after operation), the scores of combined subacromial and intravenous infusion were significantly lower than those of solitary intravenous infusion. Significant difference in the frequency of supplemental analgesic injections was observed between group A and group B (p=0.008). However, no significant difference in complication rate was observed between the two groups (p=0.562). CONCLUSIONS: Combined subacromial and intravenous patient-controlled analgesia after arthroscopic rotator cuff repair is more effective than solitary intravenous infusion without significantly increasing complications. Therefore, combined subacromial and intravenous patient-controlled analgesia could be a effective pain control method.

Influence of Early Bisphosphonate Administration for Fracture Healing in Patients with Osteoporotic Proximal Humerus Fractures

BACKGROUND: Bisphosphonates are generally known to adversely affect fracture healing because they inhibit osteoclastic bone resorption. However, some authors argue that bisphosphonates have no adverse effect on the restoration of the mechanical integrity of long bones after fractures. It is unclear whether bisphosphonates can be initiated safely in patients with acute proximal humerus fractures. The aim of this study was to determine whether the early use of a bisphosphonate affects healing and outcomes of osteoporotic proximal humerus fractures treated with a locking compression plate. METHODS: Between August 2004 and June 2013, a total of 82 osteoporotic patients who underwent locking plate fixation of proximal humerus fractures were enrolled retrospectively. The patients were divided into two groups according to the timing of the commencement of treatment with alendronate after surgery: group A (n = 34, initiation of the bisphosphonate treatment within two weeks after surgery) and group B (n = 48, control group, initiation of the treatment three months after surgery). Patients were assessed for radiographic union at 2, 6, 10, and 16 weeks, 6 months, and 1 year after surgery. Clinical assessments were performed using the Constant score and American Shoulder and Elbow Surgeons (ASES) score at 1 year after surgery. RESULTS: No significant differences were observed between the two groups with respect to radiographic and clinical outcomes after locking plate fixation. All patients obtained fracture union, and the mean time to radiographic union was similar in group A and group B (6.3 and 6.6 weeks, respectively; p = 0.67). CONCLUSIONS: This study shows that the early initiation of bisphosphonate treatment does not affect bone union or clinical outcomes in patients with an osteoporotic proximal humerus fracture treated by locking compression plate fixation.

The Accuracy of Sonoelastography in a Fatty Degeneration of Supraspinatus: A Comparison with Magnetic Resonance Images through Quantitative Assessment / 대한정형외과학회잡지

PURPOSE: Using magnetic resonance imaging (MRI) as the standard of reference, the purpose of this study was to evaluate the accuracy of sonoelastography (SE) for assessment of fatty degeneration of suprasupinatus (SSP). MATERIALS AND METHODS: A retrospective analysis was conducted in 131 shoulders of 126 consecutive patients who underwent shoulder MRI, and SE. Oblique sagittal images of SSP were obtained using SE; the SE images were evaluated by two orthopedic surgeons using a 256 degree color map image. RESULTS: When the supraspinatus fatty degenerations were based on MRI findings, the sensitivity of SE was 89.47%, specificity 92.85%, and accuracy 91.60%. The interobserver reliability of the SE findings was 'almost perfect agreement' with a weighted kappa coefficient of 0.81. By comparison of MRI with the SE findings, the grades of MRI and SE showed positive correlation (r=0.85, p< or =0.001). In addition, the occupation ratio and blue region area ratio also showed positive correlation (r=0.69, p< or =0.001). CONCLUSION: SE is valuable in quantitative assessment of the severity of fatty atrophy of the supraspinatus and has excellent accuracy, excellent correlation with MRI and conventional ultrasonography, and excellent interobserver reliability.

Influence of Oral and Intravenous Bisphosphonate for the Patients Treated Surgically in Osteoporotic Distal Radius Fracture / 대한골다공증학회지

OBJECTIVES: Purpose of this study is investigation the influence of intravenous and oral bisphosphonate to bone union and clinical results in patient treated with plate fixation in an osteoporotic distal radius fracture. MATERIALS AND METHODS: The medical records of 160 patients with an osteoporotic distal radius fracture treated with plate fixation in our hospital between January 2008 and April 2012 were reviewed retrospectively. The patients were classified by 3 groups; who did not administrate bisphosphonate after surgery as Group I (n=69), administrated oral bisphosphonate after surgery as Group II (n=44), and administrated intravenous bisphosphonate as Group III (n=47). After surgery, bone union, radiologic parameters, disabilities of the DASH score and range of motion of wrist were assessed. RESULTS: Mean time of bone union was 6.7 weeks in Group I, 6.8 weeks in Group II, and 7.1 weeks in Group III. There was no significant difference between three groups (P=0.571). Bone union rate on 6weeks shows no significant differences between three groups (P=0.16). Three groups also have no significant differences in all radiologic and clinical parameters. CONCLUSION: This study shows that early initiation of oral and Intravenous bisphosphonate did not affect bone union and clinical results compared to group who did not administrate bisphosphonate result in patient treated with plate fixation in an osteoporotic distal radius fracture.

Operative Treatment of Distal Humeral Comminuted Fractures with Orthogonal Plating

PURPOSE: To analyze the results of operative treatment for Comminuted Fracture of Distal Humerus with Transolecranon approach and Orthogonal plating. MATERIALS AND METHODS: The subjects were 22 patients with Comminuted fracture of humerus who were treated with Orthogonal plating. Patient's age, sex, type of fracture, surgical approach, method of fixation, time of operation, time of bony union, complication, range of motion were investigated, and Function of elbow was evaluated by functional evaluation of Riseborough and Radin, Mayo Elbow Performance Score (MEPS). RESULTS: Age, sex, injuried arm, operation time were not related to postoperative result. Type C2 fractures showed better results in function and range of motion (ROM) than type C3 fractures. Also early rehabilitation was important to functional recovery and ROM. The postoperative ROM was average 110. Good were 16 cases, fair were 6 cases in functional evaluation of Riseborough and Radin. Excellent were 13 cases, good were 8 cases, fair was 1 case in MEPS. CONCLUSION: Operative treatment with Transolecranon approach and Orthogonal plating showed favorable result on its function. Intraarticular comminution and early rehabilitation were closely related to postoperative function of elbow.

Treatment of Acromioclavicular Joint Injuries Using Clavicle Hook Plates

PURPOSE: To analyze results of treating acromioclavicular injuries using clavicle hook plates. MATERIALS AND METHODS: Between February 2008 and April 2010, 18 patients with acromioclavicular joint injury treated by clavicle hook plates were reviewed. Using the Rockwood classification, 7 dislocations were classified as type III injuries and 11 as type V injuries. Implant removal was done at least 3 months from initial fixation. Simple X-rays were taken for comparing the state of reduction, and clinical outcomes were evaluated by the Korean Shoulder Scoring System and the American Shoulder Elbow Society score. The average follow-up period was 9 months. RESULTS: On weight bearing X-rays, the average coracoclavicular distance showed a 114% increase compared to the contralateral side at the time of injury. It decreased to 23% by the last follow-up. The mean Korean Shoulder Scoring System and the American Shoulder Elbow Society score were 80 and 74 at the last follow-up. CONCLUSION: The immediate stability these plates provide allows rapid rehabilitation. Clavicle hook plate fixation for acromioclavicular joint dislocation is considered an effective method for ensuring satisfactory results both radiologically and clinically.

Comparison of Bone Mineral Density in Elderly Patients over 65 Years according to Presence and Types of Hip Fracture

PURPOSE: We measured the BMD of elderly patients with osteoporotic hip fracture in order to understand the relationship between BMD of each sites and hip fracture occurrence or the types, and also to suggest a reference point for starting an osteoporosis treatment program. MATERIALS AND METHODS: From July 2007 to February 2010, we investigated total 147 elderly osteoporotic hip fracture patients over 65 years. For control group, 80 patients who were over 65-year-old and did not have any fracture were selected. BMD was compared at each site between each groups statistically. RESULTS: In the comparison of femur intertrochanter and neck fracture groups, BMD of femur neck and trochanter areas and L2, L3 areas were significantly less in intertrochanteric fracture group. In the analysis according to the classification of intertrochanteric fracture, BMD of intertrochanter and Ward's triangle area were significantly less in unstable fracture group than stable one. Each of the fracture threshold of intertrochanteric and neck fracture group was -1.10 and -1.36 of the T-score in proximal femur, and -1.40 and -1.40 of the T-score in lumbar vertebrae. CONCLUSION: To examine the BMD of both proximal femur and lumbar vertebrae areas is helpful to predict the hip fracture occurrence and the type of hip fracture. And for the prevention of hip fracture in elderly patients over 65 years, we propose that the aggressive treatment of osteoporosis should be started to prevent fracture for patients with a T-score less than -1.40.

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.
