Concurrent Degenerative Cervical and Lumbar Spondylolisthesis

OBJECTIVES@#To evaluate the characteristics of concurrent degenerative cervical and lumbar spondylolisthesis.SUMMARY OF LITERATURE REVIEW: Concurrent degenerative cervical and lumbar spondylotic diseases have been reported. Given that severe spondylosis can result in spondylolisthesis, one might expect that concurrent spondylolisthesis of the cervical and lumbar spines might also be prevalent. However, the incidence of spondylolistheses in the lumbar and cervical spines might differ due to anatomical differences between the 2 areas. Nonetheless, there is minimal information in the literature concerning the incidence of concurrent cervical and lumbar spondylolisthesis.MATERIAL AND METHODS: We evaluated standing cervical and lumbar lateral radiographs of 2510 patients with spondylosis. Concurrence, age group, gender, and direction of spondylolisthesis were evaluated. Lumbar spondylolisthesis was defined as at least Meyerding grade I and degenerative cervical spondylolisthesis was defined as over 2 mm of displacement on standing lateral radiographs.@*RESULTS@#Lumbar spondylolisthesis was found in 125 patients (5.0%) and cervical spondylolisthesis was found in 193 patients (7.7%). Seventeen patients had both degenerative cervical and lumbar spondylolistheses (0.7%). Lumbar spondylolisthesis is a risk factor for co-existing cervical spondylolisthesis. Lumbar spondylolisthesis was more common in females than males, independent of advancing age. In contrast, degenerative cervical spondylolisthesis was more common in older patients, independent of gender. Anterolisthesis was more common in the lumbar spine. Retrolisthesis was more common in the cervical spine.@*CONCLUSIONS@#There was a higher prevalence of degenerative cervical spondylolisthesis in patients with degenerative lumbar spondylolisthesis.

Latissimus Dorsi Tendon Transfer for the Treatment of Irreparable Rotator Cuff Tears

PURPOSE: Massive and irreparable rotator cuff tears present a difficult treatment problem, and if further progressed, then cuff tear arthropaty may develop. We treated seven cases of massive rotator cuff tears with latissimus dorsi tendon transfer and report their clinical results. METHODS: Seven patients of mean age of 64 years (range, 51-70 years) with irreparable massive rotator cuff tears were treated using latissimus dorsi tendon transfer. The latissimus dorsi flap was harvested through an axillary approach and reattached on the greater tuberosity, using transosseous suture with non-absorbable sutures. Outcomes were assessed clinically and radiographically after an average of 48 months (range, 28-68 months). RESULTS: The VAS pain scores improved from 6.3 to 3.3 points (p=0.019). Forward flexion increased from 62° to 105°, abduction increased from 49° to 94°, and external rotation increased from 15° to 34°. Postoperative antero-posterior radiography revealed a mean 0.1 mm depression of the humeral head, without statistical the mean American Shoulder and Elbow Surgeons score improved from 44 to 76. The acromiohumeral distance showed slight increase in amount of 0.1 mm without statistical significance. There was no complication. CONCLUSION: Latissimus dorsi transfer is a useful surgical option for treating irreparable massive rotator cuff tears.

Iatrogenic Subtrochanteric Fractures Related to the Surgical Error: Two Cases Report

Iatrogenic fracture is not popular and might be recognized as a malpractice. Surgical error related to iatrogenic fracture which has occurred after an operation can be detected only by a surgeon. Stress riser fracture is another form of iatrogenic fracture also known as a Young's modulus fracture. As the majority of surgical related stress riser fractures can be preventive, the accurate prevalence is not known. The majority of fractures occurred in the weight bearing bones such as femur and tibia. The subtrochanter area is the most stress concentrated area in the human body, thus it is a common area for occurrence of stress riser iatrogenic fractures. We experienced 2 cases of stress riser iatrogenic fractures, which are related to technical errors, thus we report cases with literature review.

A Tenosynovial Giant Cell Tumor Arising from Posterior Cruciate Ligament of Knee Joint: A Case Report / 대한골관절종양학회지

Localized forms of giant cell tumor are known to arise commonly in the synovial membrane of the finger joints. Multinucleated giant cells are its characteristic pathology finding, giant cell tumor shows a low rate of recurrence after complete excision. When occurring at the knee joints, giant cell tumor manifests a wide form of symptoms, from no symptom at all, to intermittent locking. Complete excision is possible by arthroscopy, but if done incompletely, it is reported to recur in 45% of cases. We present here a case of giant cell tumor that has arisen from the anterior portion of the posterior cruciate ligament, excised by arthroscopy and followed by pathologic confirmation.

Results of Tension Band Wiring and Additional Circumferential Wiring in Treatment of Comminuted Patella Fracture

PURPOSE: The purpose of this study is to evaluate the results of tension band wiring and additional circumferential wiring in treatment of comminuted patella fractures. MATERIALS AND METHODS: A retrospective study of 67 patients with follow-up period longer than six months who underwent tension band wiring and additional circumferential wiring for comminuted patellar fracture from January 2004 to December 2012 was conducted. Analysis was based on radiological evaluation of bony union and articular surface displacement, and clinically by evaluating the postoperative function of the knee joint using the Levack scoring system. RESULTS: Only one case out of 67 (1.5%) showed nonunion without metal breakage while good bone union was achieved in all other cases. Excluding the nonunion case, range of motion was 90 degrees minimum, 135 maximum, 129 on average. Average displacement was less than 2 mm, and 64 out of 67 cases showed satisfactory outcome with excellent functional score according to the Levack scoring system. CONCLUSION: Tension band wiring and additional circumferential wiring technique for treatment of comminuted patella fractures can be considered as an effective treatment for achievement of good bone union and restoration of normal knee function.

Results of Asian Type Gamma 3 Nail in Treatment of Trochanteric Fractures

PURPOSE: This study was conducted in order to demonstrate the radiologic and clinical results of using the Asian type gamma 3 nail in treatment of trochanteric fractures. MATERIALS AND METHODS: Patients underwent operations with gamma 3 nails between August 2010 and August 2012. For the radiologic evaluation, we analyzed bone quality, fracture pattern, reduction quality, union period, and position of lag screw (tip-apex distance, Cleveland index). For the clinical evaluation, we analyzed mobility score of Palmer and Parker and Jensen's functional score. RESULTS: The mean union was taken at 17.4 weeks (14-25 weeks). Two cases (4.3%) underwent reoperation due to cutting out of the hip screws. The clinical outcomes of Parker and Palmer's average mobility score changed from 7.3 to 5.8 (79%), Jensen's functional score was 1.3 to 1.8 (72%). CONCLUSION: We achieved excellent clinical and radiological outcomes; therefore, Asian type gamma 3 nail is effective in treatment of trochanteric fractures of the femur in Korea.

Analysis of the Fixation Failure in Intertrochanteric Hip Fractures Treated with Hip Nailing

PURPOSE: To analyze the patterns of and risk factors for fixation failure after hip nailing in intertrochanteric (IT) hip fractures. MATERIALS AND METHODS: Fourteen patients who sustained a fixation failure after hip nailing for IT hip fractures were enrolled in this study. The mean age at the index surgery was 74.5 years and the mean time to the fixation failure was 6.6 weeks. All of the serial radiographs up to the fixation failure and pre-operative 3-D computed tomography were analyzed. RESULTS: According to AO classification, there were 7 stable fractures and 7 unstable ones. Of the total of 14 cases, 10 showed a comminution of the greater trochanter tip and incomplete anatomical reduction of the medial and anterior cortex at the fracture site. Of the 10 cases with appropriate position of the lag screw within the femoral head, 9 showed a high pertrochanteric fracture (HPF) pattern. The mechanism of the fixation failure was rotation of the femoral head in 7 of 9 cases with HPF and varus collapse of the proximal fragment in 4 of the other 5 cases. CONCLUSION: The HPF pattern, the comminution of the greater trochanter tip, and incomplete reduction of the medial and anterior cortex may be additional risk factors of fixation failure after treating IT hip fractures with hip nailing in.

The Effect of Cefazolin on Mechanical Properties and Antibacterial Reactions of Calcium Phosphate Cement / 대한정형외과학회잡지

PURPOSE: The purpose of this study is to evaluate the change of mechanical properties and the effect of antibacterial reactions in calcium phosphate cement (CPC) mixed with cefazolin. MATERIALS AND METHODS: We made CPC and a sodium alginate solution and we mixed in variable dosages of cefazolin and then we made a standard sized cement mold. With that we performed compression stress tests, drug releasing tests and antibacterial tests. RESULTS: We found the typical appearance of hydroxyapatite (HA) in the cement mixed with cefazolin. The compressive strength of the cement mixed with cefazolin was higher than that of the cement not mixed with cefazolin and the higher strength cement had a smaller pore size and less porosity. The sodium alginate solution showed the maximum compressive strength at 2 & 4 wt%, but this was decreased at 6 wt%. Cefazolin was released in proportion to the concentration for the first 8 days on the drug releasing test and then a similar amount was released until the tenth day. An antibacterial effect was detected at all dosages of cefazolin on the antibacterial test. CONCLUSION: The compressive strength of the cement mixed with cefazolin was higher than that of the cement not mixed with cefazolin. The drug was released from the cement in a proper fashion and the antibacterial effect was preserved.

Undetected Incomplete Stress Fracture in the Proximal Femur of a Patient with Paget's Disease: A Case Report

Paget disease is a well-documented skeletal disease and it has an increased rate of tissue breakdown due to the excessive turnover of osteoblasts and osteclasts. Stress fracture is one of the most common complications in the late phase of Paget disease, but the clinical presentation of incomplete pathologic fracture is rare and this is an important clue to plan the treatment. We experienced a case of Paget's disease in a 74 year old woman with a periprosthetic fracture from the undetected, imcomplete stress fracture in the proximal femur.

Operative Treatment of Bilateral Tibial Tuberosity Fractures in Adolescent: A Case Report

Bilateral avulsion fractures of the tibial tubercles are extremely rare. There is no case report about this in Korean literature. We present simultaneous bilateral tibial tuberosity fractures in 14-year-old adolescent male fell on the ground during running. These fractures were managed by open reduction and screw fixation. We gained complete union and removed metal after 6 months. Functional results were excellent 6 month after surgical treatment.

Deep Submuscular Parosteal Angiomyxolipoma in a Child / 대한골관절종양학회지

Angiomyxolipoma is a rare variant of lipoma, which is described by Mai, 1996, at first. The nine cases of which have been reported to date. Microscopically, the lesion consists of adipose tissue with the paucicellular myxoid areas and fat tissue with numerous thin, dilated, and congestive blood vessels. The reported cases mostly located to the superficial layer on the scalp, subungual, extremities in adults. We report one case of angiomyxolipoma located in the submuscular and parosteal area in the distal femur around knee joint in a child.

Arthroscopic Transosseous Suture Repair for Bankart Lesion with a Flexible Drill Device: An Experimental and Preliminary Clinical Report

PURPOSE: Too develop a flexible drill device that can be inserted into the shoulder joint so that arthroscopic transosseous suture repair for Bankart lesion is possible. MATERIALS AND METHODS: We created a device composed of a flexible drill unit and a guide pipe unit. The flexible drill unit was made of flexible multifilament wires (1.2 mm in diameter) that was twisted into one cord so that it can flex in any direction and a drill bit (1.2 mm in diameter) that is attached onto one end of the flexible wire. The guide pipe unit was a 150 mm long metal pipe (2.0 mm in inner diameter and 3.0 mm in outer diameter), with one end bent to 30 degrees. The flexible drill set was inserted into the shoulder joint through the posterior portal of the joint. The guide pipe component was placed onto the medial wall of the glenoid so that the pipe was placed 5 mm posterior to the margin of the anterior glenoid rim. The flexible drill was driven through the glenoid by the power drill so that holes were made in the glenoid. A non-absorbable suture was passed through the hole. Tying of a sliding knot tying was accomplished over the capsule and labrum after making a stitch through the capsule and labrum with a suture hook loaded with suture passer. The same procedures were done at the 2 and 4 O'Clock positions of the glenoid. RESULTS: Five cases with Bankart lesion received arthroscopic transosseous repair with our flexible drill device. There were no intraoperative problems. Neither redislocation nor subluxation was reported at final follow-up. CONCLUSION: Arthroscopic transosseous suture repair without suture anchors and easy tying of a sliding knot are possible with a flexible drill set.

Interposition Arthroplasty with Pectoralis Major Muscle Transfer for the Shoulder Arthropathy: 2 Cases Report

Interpostion arthroplasty with allograft has been known as a useful option for the shoulder arthropathy, but it has a limitation to immune response. We performed the pectoralis major muscle transfer for shoulder arthropathy. From January 2007 to December 2007, we performed the pectoralis major muscle transfer in 2 patients. They were 1 man and 1 woman, and the mean age of the patients was 70 years (range, 65 to 75). The average follow-up after surgery was 13 months (range, 12 to 14). We analyzed the clinical results by the American Shoulder and Elbow Surgeons (ASES) Score, and evaluated the pain by Visual Analogue Scale. The level of pain reduced from a preoperative average of 10 to a postoperative average of 1. The ASES scores increased from a preoperative mean of 9 to a postoperative mean of 58. These results indicated that interposition arthroplasty with the pectoralis major muscle transfer is a reliable treatment method for the shoulder arthropathy improving shoulder pain, and patient satisfaction.

Non-Familial Osteopoikilosis around the both Hip Joints: a Case Report

Osteopoikilosis is an osteosclerotic dysplasia of an unknown origin, and this malady is both extremely rare and hereditary and sporadic in nature. It is sometimes asymptomatic and incidentally diagnosed with radiologic images. A familial history and concomitant disease might also be present. In this study, we report on a 31-year-old woman who suffers from pelvic pain and she was diagnosed as having osteopoikilosis around both hip joints by the radiological images. We also review the relevant medical literature.

Surgical Treatment of Brucellar Spondylodiscitis with Epidural Abscess: A Case Report / 대한척추외과학회지

Brucellosis is a well known systemic, zoonotic disease that can affect many organs. We report a rare case of spondylodiscitis with an epidural abscess caused by brucellosis. The patient was treated surgically for severe pain and concomitant devastating neurological deficit. A diagnosis of spondylodiscitis or an epidural abscess due to brucellosis must be considered when acute back pain, radiating pain and febrile episodes occur, particularly in people in a high risk group.

Bilateral Traumatic Anterior Dislocation of the Hip with an Unstable Lumbar Burst Fracture

Traumatic anterior dislocation of the hip is rare. Bilateral traumatic anterior dislocation is an even rarer injury; indeed, only 5 cases have been reported in the English literature. We describe a case of a bilateral traumatic anterior dislocation of the hip and a concomitant unstable lumbar burst fracture following a mechanism of injury distinctly different from other reports.

The Effect of Prophylactic Cable Fixation for Prevention of Femoral Fractures in Hemiarthroplasties

PURPOSE: The purpose of this study was to assess the effect of a prophylactic cable fixation for prevention of femoral fractures in cementless bipolar hemiarthoplasties. MATERIALS AND METHODS: Forty-eight cementless bipolar hemiarthroplasties with prophylactic cable fixations on the femur were performed in patients >65 years of age between January 2004 and August 2008 (group 1). The control group which did not undergo prophylactic cable fixation included 48 cases (group 2). The mean age was 75.4 years (group 1) and 73.6 years (group 2). The patients were followed up for an average of 19.1 (group 1) and 18.3 months (group 2). The intra-operative fracture rates were compared. Additionally, operative time, estimated blood loss (EBL), and length of hospital stay were compared. Radiologic assessment for stem stability was performed. Clinical assessment was evaluated by the thigh pain and Jensen's functional score, and Parker & Palmer's mobility score. RESULTS: There was no fractures in the cabled group (1), and 4 fractures (8.3%) in the control group (2; p=0.041). The mean operative time was 172 minutes (1) and 162 minutes (2), the EBL was 866 cc (1) and 855 cc (2), and the duration of admission was 36 (1) and 35 days (2), respectively. Radiologically, subsidence was 1.59 mm (1) and 1.67 mm (2). Clinically, one (1) and two (2) thigh pains were recorded and the functional score of Jensen was 2 (1) and 2.2 points (2), and the mobility score of Parker and Palmer was 5.2 (1) and 5.3 points (2), respectively. CONCLUSION: Prophylactic cable fixation is effective for reducing intra-operative femoral fractures.

The Results of Proximal Femoral Nail Antirotation: A Comparative Study with Proximal Femoral Nail

PURPOSE: This study was performed to compare the results between PFNA (Proximal Femoral Nail Antirotation) and PFN (Proximal Femoral Nail) in the treatment of peritrochanteric fracture. MATERIALS AND METHODS: The patient group with PFNA (n=24, group I) was taken from operations between February, 2007, and March, 2008, whereas the PFN patient group (n=24, group II) were taken from January, 2005, to January, 2007. Both groups were carefully compared with regard to operation time, estimated blood loss, amount of transfusion, ICU care, amount of drainage, average duration of admission, intra- and postoperative complications, radiologic union, Tip Apex Distance (TAD), the change of neck shaft angle, the sliding length of lag screw, Jensen's functional score, and Paker and Palmer's mobility score. RESULTS: The results of our study showed statistical (P0.05). CONCLUSION: PFNA appears to be more effective than PFN for the treatment of peritrochanteric fractures of the proximal femur.

Effect of early oral intake on postoperative bowel function in patients undergoing lower extremities surgery under epidural anesthesia / 대한마취과학회지

BACKGROUND: Early oral intake (EOI) associated with early recovery of normal bowel function has been shown to be an important determinant for improving patients' satisfaction. We investigated the tolerability of EOI and its effects on the recovery of bowel function after epidural anesthesia. METHODS: A prospective randomized trial of patients undergoing lower extremities surgery under epidural anesthesia was performed. A liquid drink was given to 150 patients in the EOI group 1 hours after surgery, and to 150 patients in the delayed oral intake (DOI) group 8 hours after surgery. We recorded presence of bowel sounds immediately after operation, symptoms of ileus, time to the first flatus, time to the first defecation, degree of appetite before the first meal, and patients' satisfaction. RESULTS: There was no significant difference in the presence of immediate postoperative bowel sounds, the degree of appetite before the first meal, mild ileus, and severe ileus between groups. Time to the first flatus and time to the first defecation in the EOI group were shorter than those of the DOI group. The patients' satisfaction in the EOI group was higher than that of the DOI group. CONCLUSIONS: For uncomplicated patients undergoing lower extremities under epidural anesthesia, beginning oral hydration as early as 1 hour after the operation is safe and well tolerated and resulting in faster recovery of bowel function and higher patients' satisfaction.
