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.

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’.

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.

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.

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.

Baker's Cyst Filled with Hematoma at the Lower Calf

Baker's cyst is a distension of the gastrocnemius-semimembranosus bursa of the knee, which communicates with the posterior portion of the joint capsule. Baker's cyst is commonly located in the inferomedial or superficial layers of the knee joint and rarely extends laterally or proximally. Complications of Baker's cysts are dissection, rupture, pseudothrombophlebitis, leg ischemia, nerve entrapment, and compartment syndrome. However, hematomas in the Baker's cyst have not been reported in Korea. We report a rare case of hematoma in the Baker's cyst with subfascial extension into the calf. The hematoma was demonstrated by magnetic resonance imaging and removed by mass excision.

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.

Missed Fractures in Severely Injured Patients

PURPOSE: The purpose of this study is to analyze anatomic distributions, diagnostic methods, and prognosis of missed fractures in patients with severe injury. MATERIALS AND METHODS: A review of single-institutional medical records between January 2001 and May 2012 identified 58 patients with 62 delayed diagnoses of fractures among 4,643 severely injured patients older than 20 years with Injury Severity Scores higher than 16. We evaluated combined injuries, location of fractures, diagnostic methods, and reasons for missed diagnosis at initial exam. RESULTS: Among 62 missed fractures, there were eight cases of spine fracture, 10 cases of peri-shoulder joint fracture, eight cases of upper extremity fracture, 10 cases of pelvis of acetabulum fracture, and 26 cases of lower extremity fracture. Head injury was the most common concomitant injury (23 cases). Initially missed fractures were most commonly discovered by official reading by radiologists. The most common reasons for misdiagnosis were the use of improper radiologic study and missed-reading of proper radiologic studies. CONCLUSION: In order to prevent misdiagnosis of fractures in patients with severe injury, meticulous physical examination with suspicion of fractures should come first. In addition, obtaining proper radiologic study and thorough evaluation of radiologic images are important to decreasing the rates of missed fracture diagnoses. In addition, thorough surveillance for ipsilateral fractures is important in extremities with identified fractures.

Usefulness of Contralateral Indirect Decompression through Minimally Invasive Unilateral Transforaminal Lumbar Interbody Fusion

STUDY DESIGN: Retrospective study. PURPOSE: This study aims to investigate the clinical and radiological results of contralateral indirect decompression through minimally invasive unilateral transforaminal lumbar interbody fusion (MI-TLIF). OVERVIEW OF LITERATURE: Several studies have proposed that blood loss and operation time could be reduced through a unilateral approach, although many surgeons have forecast that satisfactory foraminal decompression is difficult to achieve through a unilateral approach. METHODS: The study included 30 subjects who had undergone single-level MI-TLIF. Visual analogue scale (VAS) and Oswestry disability index (ODI) were analyzed for clinical assessment. Disc height, segmental lordosis, and lumbar lordosis angle were examined for radiological assessment. The degree of contralateral indirect decompression was evaluated through a comparative analysis, with a magnetic resonance imaging (MRI) performed preoperatively and at one year postoperatively. RESULTS: Intraoperative blood loss volume was 308.75 mL in the unilateral approach group (UAP), and 575.00 mL in the bilateral approach group (BAP), showing a statistically significant difference. Operation time was 139.50 minutes in the UAP group, and 189.00 minutes in the BAP group, exhibiting a statistically significant difference (p0.05). CONCLUSIONS: Satisfactory results were acquired with MI-TLIF conducted through the unilateral approach of contralateral indirect decompression, in alignment with the bilateral approach. Therefore, contralateral indirect decompression is thought to be a useful procedure in reducing the operation time and volume of blood loss.

Deformity Correction by Femoral Supracondylar Dome Osteotomy with Retrograde Intramedullary Nailing in Varus Deformity of the Distal Femur after Pathologic Fracture of Giant Cell Tumor

Angular deformities of the distal femur occur in congenital diseases or due to acquired causes, such as malunion after a fracture of the distal femur. Angular deformities of the lower extremities affect the mechanical axis, causing changes in the weight pressure on the articular surface. As a result, angular deformities quicken the progression of osteoarthritis. Therefore, correction of deformities should be performed to prevent the progression of osteoarthritis. Distal femoral osteotomy is one of the methods to correct angular deformities in unicompartmental osteoarthritis. However, femoral supracondylar dome osteotomy with retrograde intramedullary nailing in the distal femur with a varus deformity has been rarely reported. Herein, we describe a technique for femoral supracondylar dome osteotomy with retrograde intramedullary nailing in a varus deformity after a pathologic fracture of giant cell tumor in the distal femur with a review of the relevant literature.

Influence of Posterior Tibial Slope on Stability and Second-Look Arthroscopic Findings after Anterior Cruciate Ligament Reconstruction / 대한정형외과학회잡지

PURPOSE: The purpose of this study was to analyze the influence of posterior tibial slope on stability in clinical and second-look arthroscopic evaluation after anterior cruciate ligament (ACL) reconstruction. MATERIALS AND METHODS: From 2000 to 2011, 124 patients who underwent ACL reconstruction using an allogaft were enrolled in this study. A posterior tibial slope between 0degrees and 4degrees was found in 28 patients (group A), between 5degrees and 9degrees in 64 patients (group B), and greater than 10degrees in 32 patients (group C). We evaluated stability using the Lachman test and a KT-2000 arthrometer. In second-look arthroscopy, grafted tendons were evaluated based on the tension, rupture, and synovial coverage. RESULTS: In clinical evaluation for stability, mean KT-2000 arthrometer and Lachman test at last follow-up showed no statistically significant differences depending on posterior tibial slope. Second-look arthroscopic findings showed no statistically significant difference between groups A and B (p=0.91). However, statistically significant relations were observed between groups A and C (p=0.03), and between groups B and C (p=0.02). CONCLUSION: The results of this study suggest that patients who underwent ACL reconstruction with higher posterior tibial slope (> or =10degrees) have more lax tension in second-look arthroscopy, but not in clinical stability tests.

Difference of Fusion Rate in Minimally Invasive Transforaminal Lumbar Interbody Fusion with Autobone and Hydroxyapatite according to Mixture Ratio and Amount of Bone Graft / 대한정형외과학회잡지

PURPOSE: The aim of this study is to analyze the fusion rate according to the mixture ratio and the amount of bone graft in minimally invasive transforaminal lumbar interbody fusion (MI-TLIF). MATERIALS AND METHODS: This study included 92 subjects who underwent MI-TLIF. Patients were classified into either group I, in which patients received transplantation with only autogenous bone, group II, in which patients received transplantation with hydroxyapatite mixed with autogenous bone by more than 50%, or group III, in which patients received transplantation with hydroxyapatite mixed with autogenous bone by less than 50%. For analysis of the correlation of amount of bone graft with fusion rate, patients were divided into group A, having less than 12 ml of bone graft, and group B, having more than 12 ml of bone graft. Visual analogue scale and Oswestry disability index were used for clinical assessment, and Burkus' classification method was used for evaluation of bone fusion. RESULTS: Fusion rates of groups I, II, and III according to the mixture ratio were 90.9%, 86.5%, and 86.2%, respectively. The fusion rate increased as the autobone ratio became higher; however, no significant difference was found (p=0.16). The fusion rates were 81.5% and 92.5% in group A and group B, respectively, which were classified according to the volume of bone graft, showing a significant increase in groups with bone graft volume more than 12 ml (p=0.03). CONCLUSION: A significantly high fusion rate was observed when bone graft volume was more than 12 ml in MI-TLIF. More than 12 ml of bone graft volume is essential for achievement of a satisfactory fusion rate.

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.

Perioperative Safety and Efficacy of Multilevel Minimally Invasive Transforaminal Lumbar Interbody Fusion: Comparison with Conventional Open Surgery / 대한정형외과학회잡지

PURPOSE: This study was aimed to examine the ways to reduce bleeding through minimally invasive multi-segmental fusion by comparing the results of minimally invasive transforaminal lumbar interbody fusion versus those of conventional posterior interbody fusion depending on the number of fused segment. Moreover, the study identified how the new method of fusion contributed to reducing postoperative complications and to fast recovery. MATERIALS AND METHODS: This is a retrospective study conducted on 367 spinal stenosis patients who had been followed up for at least one year (170 patients underwent minimally invasive transforaminal lumbar interbody fusion and 197 patients underwent conventional posterior interbody fusion). The study examined blood loss volume, postoperative drainage volume, operation time, visual analogue scale score, pre- and post-operative levels of protein and albumin, as well as postoperative bed rest period between the two groups. Moreover, the study analyzed the presence of complications during the peri-operative period. RESULTS: The minimally invasive fusion group exhibited a statistically significant decrease in intraoperative bleeding than the conventional infusion group when the number of fused segments in each group was compared. In addition, the difference in the two groups showed a statistically significant increase as the numbers of fused segments rose (p<0.05). On the other hand, a statistically significant increase was shown in the operation time between the minimally invasive fusion group and the conventional fusion group. The difference in the two groups showed a statistically significant increase as the distance of fused segments was extended (p<0.05). CONCLUSION: Minimally invasive transforaminal lumbar interbody fusion is thought to be a useful surgical method to minimize bleeding when the limitations of minimal invasive fusion are supplemented by shortening the operation time.
