Surgical treatment of the neglected achilles tendon rupture with Hyalonect.

BACKGROUND: The purpose of this study was to report the management and outcomes of ten patients with chronic Achilles tendon rupture treated with a turndown gastrocnemius-soleus fascial flap wrapped with a surgical mesh (Hyalonect). METHODS: Ten men with neglected Achilles tendon rupture were treated with a centrally based turndown gastrocnemius fascial flap wrapped with Hyalonect. Hyalonect is a knitted mesh composed of HYAFF, a benzyl ester of hyaluronic acid. The Achilles tendon ruptures were diagnosed more than 1 month after injury. The mean patient age was 41 years. All of the patients had weakness of active plantarflexion. The mean preoperative American Orthopaedic Foot and Ankle Society score was 64.8. RESULTS: The functional outcome was excellent. The mean American Orthopaedic Foot and Ankle Society score was 97.8 at the latest follow-up. There were significant differences between the preoperative and postoperative scores. Ankle range of motion was similar in both ankles. Neither rerupture nor major complication, particularly of wound healing, was observed. CONCLUSIONS: For patients with chronic Achilles tendon rupture with a rupture gap of at least 5 cm, surgical repair using a single turndown fascial flap covered with Hyalonect achieved excellent outcomes.

The role of simple elbow dislocations in cubitus valgus development in children.

PURPOSE: We investigated the functional and radiological outcomes of conservatively treated simple traumatic elbow dislocations and subsequent incidence of cubitus valgus development in children. METHODS: Eleven patients (one female, ten male; mean age 9.8 years, range seven to 12 years) who presented to our hospital with simple elbow dislocations and were conservatively treated between July 2008 and September 2010 were included in the study. All were posterolateral closed dislocations. None of the patients had accompanying elbow fractures. All patients had pre- and postoperative radiographic examinations. The carrying angle of the involved elbow was measured and compared to the contralateral non-injured elbow during follow-up. The incidence and severity of cubitus valgus development was assessed. The functional and clinical outcomes were evaluated using the Mayo Elbow Performance Scale. The mean monitoring period was 24.3 months (range 19-30 months). RESULTS: All patients had satisfactory good and excellent results (85-100 points; mean 96.8 points) according to the Mayo Elbow Performance Scale. The final average elbow flexion was 137° (range, 130-145°) and average extension was 8.6° (range 0-20°) with full supination and pronation in traumatic elbow. Four patients (36.4%) had an average increase (cubitus valgus) of 14.5° (10-20°) in carrying angle compared to the other elbow. CONCLUSIONS: While isolated traumatic dislocation of the elbow is uncommon among children, it can be successfully treated by urgent closed reduction, proper fixation of the elbow and appropriate timely rehabilitation. However, it should be considered that some patients may develop cubitus valgus deformity in a later period. Therefore, each patient with a simple traumatic elbow dislocation should be followed, and the parents should be informed of the potential for any deformity development.

Effects of calcitonin on knee osteoarthritis and quality of life.

There has been a recent interest in calcitonin as a potential treatment for osteoarthritis, based on its metabolic activities in both bone turnover and cartilage. The aim of this study was to evaluate the effects of nasal form calcitonin on knee osteoarthritis and quality of life in women who receive calcitonin treatment for postmenopausal osteoporosis. Two hundred and twenty postmenopausal women, aged between 55 and 65 years with knee pain and knee osteoarthritis, graded II-III by using Kellgren-Lawrence radiographic scoring system, were included. Western Ontario and McMaster Universities (WOMAC) osteoarthritis index, the quality of life questionnaire of the European Foundation for Osteoporosis (QALEFFO-41) and visual analog scale were used for the algofunctional assessments. Need of rescue analgesic was recorded. Pain (P < 0.001), stiffness (P < 0.05), functional capability (P < 0.05) and total score of WOMAC (P < 0.05) revealed statistically significant improvements after 3 months of the treatment and remained consistent throughout 1 year of the treatment period. Participants experienced significant reductions in WOMAC perceptions of pain (-53 %), joint stiffness (-44 %) and limitations in physical function (-49 %) at the end of 1 year of calcitonin treatment. Need of rescue analgesic intake was reported to have decreased approximately by 60 % at the end of the 1-year treatment period. QUALEFFO_41 scores improved: 37.6 (baseline), 30.9 (3 months), 28.0 (6 months) and 24.4 (1 year). In conclusion, nasal calcitonin treatment provided dual action on osteoporosis and osteoarthritis with significant improvements in quality of life and algofunctional results in knee osteoarthritis.

Hyalonect in the treatment of pseudarthrosis.

OBJECTIVE: The aim of this study was to evaluate union rates and complications of Hyalonect, a knitted mesh composed of HYAFF, a benzyl ester of hyaluronic acid, and a naturally occurring constituent of the extracellular matrix, for the treatment of pseudarthrosis. METHODS: The study included 11 patients (8 male, 3 female; mean age: 44.6 years; range: 23 to 57 years) operated for pseudarthrosis using Hyalonect. Average time between initial treatment and surgical procedure was 12.9 (range: 8 to 48) months. Pseudarthrosis of the tibia, femur and humerus was present in 4, 2 and 5 patients, respectively. All patients had undergone prior surgery (1 to 6 times). Each patient underwent open reduction and internal fixation. Allograft was applied to the pseudarthrosis area and covered with Hyalonect. Mean follow up period was 31 (range: 12 to 48) months. RESULTS: Union was achieved in all patients after an average of 6 (range: 4 to 8) months. One patient had a discharge for two weeks. Another developed an infection which responded well to appropriate antibiotic treatment. No malunion or implant failure was observed. One patient with pre-existing radial nerve palsy maintained the condition. CONCLUSION: Use of Hyalonect appears to be a safe method with a positive impact on union in the surgical treatment of pseudarthrosis, particularly in the absence of any infection.

Hip structural changes and fracture risk in osteopenia and osteoporosis.

OBJECTIVE: Although bone mineral density (BMD) is an important predictor of hip fracture, there is a large overlap of BMD values between those who fracture their hips and those who do not. The aim of this study was to evaluate differences in the structural parameters of the hip in patients with osteopenia and osteoporosis in the hip region and to assess their relationship with osteoporotic fracture risk, age and gender. MATERIALS AND METHODS: In this observational retrospective study, 150 patients with osteopenia (100 postmenopausal women and 50 men ≥50 years of age) and 125 patients with osteoporosis in the hip (100 postmenopaussal women and 25 men ≥50 years of age) were included. In addition to densitometry measurements by DEXA (Dual Energy X-ray Absorbimetry), structural variables were determined using the Hip Strength Analysis program (HSA). RESULTS: In logistic regression analyses, the femoral neck BMD (odds ratio (OR), 2.6; 95% Confidence Interval (CI) 1.8-3.8), age (OR per 10 years 1.4; 95% CI, 1.1-1.9), femoral neck shaft angle (NSA) (OR 1.5; 95% CI, 1.2-2.1), Femur Strength Index (FSI) (OR 1.6; 95% CI 1.3-2.2), and Cross sectional area (CSA) (OR 1.6; 95% CI 1.2-2.1) were all associated with osteoporotic fractures in women and men. Osteopenic patients had smaller femoral neck-shaft angles (NSA) compared to osteoporotic patients (p<0.05). This angle was larger in women (p<0.05); and women had decreased (FSI) (p<0.001) and CSA (p<0.05), which cause increased fracture risk. CONCLUSION: Spatial distribution of bone tissue is a useful determinant of fracture risk.

Relationship between meniscal tears and tibial slope on the tibial plateau.

OBJECTIVE: The geometry of the tibial plateau has a direct influence on the translation and the screw home biomechanics of the tibiofemoral joint. Little information on the relationship between the tibial slope and meniscal lesions is available. The objective of this retrospective study was to examine the effect of the tibial slope on the medial and lateral meniscus lesions in patients with intact ACLs. MATERIALS AND METHODS: The MRIs and lat roentgenograms of 212 patients with meniscus lesions were examined to determine the possible effect of the tibial slope on meniscal tears. First, the anatomic axis of the proximal tibia was established. Then, the angle between the line drawn to show the tibial slopes (medial and lateral) and the line drawn perpendicular to the proximal tibial anatomic axis was established on MRI. The patients with previously detected meniscus lesions were classified into three categories: patients with only medial meniscal tear (Group 1, 90 patients); patients with only lateral meniscal tear (Group 2, 15 patients); and patients with both medial and lateral meniscal tear (Group 3, 19 patients). Group 4 had no meniscal tear (88 patients). The MRIs of the patients who had applied to the Orthopedic Outpatient Clinic with patellofemoral pain and no meniscal tear were included as the control group. RESULTS: The average tibial slope of the medial tibial plateau was 3.18° in group 1, 3.64° in group 2, 3° in group 3, and 3.27° in group 4. The average tibial slope of the lateral tibial plateau was 2.88° in group 1, 3.6° in group 2, 2.68 in group 3, and 2.91 in group 4. The tibial slope on the medial tibial plateau was significantly larger than the lateral tibial plateaus in group 1 and group 4 (p<0.05). In group 2, there was no statistically significant difference between the tibial slopes of the two sides (p>0.05). In addition, the tibial slope on the lateral side of group 2 was significantly larger than that of groups 1, 3, and 4 (p<0.05). CONCLUSION: An increase in the tibial slopes, especially on the lateral tibial plateau, seems to increase the risk of meniscal tear.

Accuracy of anterior glenohumeral injections: a cadaver study.

PURPOSE: Intra-articular glenohumeral injections have an important role for therapeutic benefit and diagnostic information. Therefore, it is very important that the injected material should reach its desired target. This study assessed the accuracy of an anterior intra-articular injection in fresh cadavers. METHODS: A total of 50 shoulders of 25 fresh cadavers were included in the study. Anterior placement of a spinal needle using a location just 1 cm lateral to the coracoid, without radiographic assistance were performed. After the needle was placed and estimated to be intra-articular 1 cc of acrylic dye was injected into the joint to determine accuracy of position. RESULTS: Ninety-six percent of injections were accurately administered into the glenohumeral joint and 4% in the surrounding soft tissues and capsule. CONCLUSION: Based on our cadaveric study, an unassisted anterior injection to the glenohumeral joint could be accurately placed.

Shoulder pain and functional consequences: does it differ when it is at dominant side or not?

PURPOSE: The shoulder complex plays an integral role in the activities of daily living and the limitation of its function can greatly affect the patient. The aim of this study was to research the functional consequences of painful conditions in the shoulder region. METHODS: Sixty five adult patients with shoulder pain for longer than one month in duration were included to the study. Dominant hands of the patients were determined. The subjects were divided into two groups: shoulder pain at the dominant upper extremity (Group I) or the nondominant one (Group II). The subjects were evaluated for shoulder pain with visual analog scale (VAS), range of motion and functional status with the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. RESULTS: In Group I, DASH score was significantly correlated with the VAS score measuring the pain during activity (p< 0.0001, r=0,625). In Group II, no relationship between DASH score, VAS scores and any other parameters was detected. CONCLUSION: The most important parameter disturbing the daily living of a patient with shoulder disease is the pain at the shoulder of dominant extremity occurring in active movement.

Comparison of carpal tunnel injection techniques: a cadaver study.

The purpose of the study was to evaluate the accuracy of injections into the carpal tunnel using three different portals in cadavers, and to define safe guidelines. In this study, 150 wrists of 75 cadavers (54 male, 21 female) were included. To compare three injection sites, 50 wrists of 25 cadavers were used for each technique; we used 23 gauge needles, and acrylic dye. The first injection technique: the needle was inserted 1cm proximal to the wrist crease and directed distally by roughly 45 in an ulnar direction through the flexor carpi radialis tendon. The second injection technique: the needle was inserted into the carpal tunnel from a point just ulnar to the palmaris longus tendon and 1cm proximal to the wrist crease. The third injection technique: the needle was inserted just distal to the distal skin crease of the wrist in line with the fourth ray. The first injection technique gave the highest accuracy rate, and this was also the safest injection site. Median nerve injuries caused by injection was seen mostly with the second technique. Although a steroid injection may provide symptomatic relief in patients with carpal tunnel syndrome, the median nerve and other structures in the carpal tunnel are at risk of injury. Because of that, the injection should be given using the correct technique by physicians skilled in carpal tunnel surgery.

Effects of calcitonin on the biomechanics, histopathology, and radiography of callus formation in rats.

BACKGROUND: This study was designed to examine the effect of salmon calcitonin on fracture repair. METHODS: A transverse middiaphyseal fracture of the right tibia was surgically induced, and stabilized by an intramedullary Kirschner wire. Eighty male Wistar rats were arbitrarily assigned to four groups of 20 animals each. Groups I and II were the controls and did not receive any medication but did receive placebo injections. The other two groups received 5 IU/kg/day salmon calcitonin intramuscularly for 6 weeks (Group III) or for 10 weeks (Group IV) postoperatively. The formation and healing of the bones were determined by radiographic and histopathological analyses and by biomechanical tests. RESULTS: In radiographic examinations, there were no statistically significant differences between groups I and III at week 6 or between groups II and IV at week 10. However, the histopathological evaluation scores were higher in the calcitonin group at the early stage (6 weeks) of fracture healing, which indicates a more mature callus formation (P < 0.05). The values for maximum torsional moment during fracture were higher in the calcitonin group in both stages of fracture healing (P < 0.01). CONCLUSIONS: This study could have two important clinical implications. (1) Higher scores for the histopathological evaluation and a greater resistance to moment force applied at an early stage (week 6) of fracture healing imply that calcitonin intake might enable us to allow earlier mobilization and weight-bearing in clinical cases with rigid fixation. (2) At a late stage of fracture healing (week 10), the significantly better (P < 0.0001) results obtained in the biomechanical parameters used might imply that calcitonin intake could enable us to perform early implant removal, and strongly suggest that the strength and quality of the callus formation could be improved by administering calcitonin following a fracture.

Skin traction in hip spica casting for femoral fractures in children.

BACKGROUND: The purpose of this study was to evaluate the skin traction in hip spica casting when applied as the standard treatment for children with femoral shaft fractures. METHODS: A total of 207 patients with femoral fractures were treated with this method. The average age was 4.7 years. After the application of skin traction, the fracture of the femur was reduced and was placed in a hip spica cast. Traction was continued in the cast. RESULTS: All fractures united within 4-8 weeks. No significant residual angular deformities were seen in any of the children. The only complication was refracture in two children who fell after removal of the cast. None of the children required external shoe lifts, epiphysiodesis, antibiotics, irrigation, or débridement. CONCLUSIONS: Skin traction and a well-molded hip spica cast is a safe, reliable treatment option for isolated, closed femoral fractures in children 2-7 years of age.

Cervical spinal brucellosis causing epidural and prevertebral abscesses and spinal cord compression: a case report.

BACKGROUND CONTEXT: Cervical involvement due to spinal brucellosis is quite rare. Although surgery usually is not necessary in spinal brucellosis, most of the patients with cervical involvement require surgical treatment because of the high rate of neurological involvement and spinal cord compression. PURPOSE: To present a unique case with cervical spinal brucellosis with epidural and paravertebral abscesses and to discuss the treatment alternatives of this disease. STUDY DESIGN: A case report. METHODS: A 61-year-old patient with spinal cord compression syndrome due to cervical spinal brucellosis was reported. He was treated by triplet antibiotherapy for 24 weeks. On magnetic resonance imaging, spinal cord compression caused by epidural abscess and granulation tissue, and prevertebral abscess were seen. RESULTS: At the end of the treatment, there were no complaints, neurological findings, or positive infection markers. There was not epidural compression on control magnetic resonance imaging. CONCLUSIONS: Surgery may not be required in all cervical spinal brucellosis cases with epidural compression and neurological involvement. Conservative treatment with close observation may be sufficient in these patients who are usually older people.

Comparison of four different intra-articular injection sites in the knee: a cadaver study.

Although intra-articular knee injection is not a complicated procedure, it could be difficult to assess whether the tip of the needle lies free in the joint or is embedded in synovium or other intra-articular soft tissues. The purpose of this study was to evaluate the accuracy rate of intra-articular injection using anteromedial (AM), anterolateral (AL), lateral midpatellar (LMP), and medial midpatellar (MMP) portals in cadavers. In this study 156 knees of 78 fresh cadavers were included. Anterolateral and AM injection to both knees of 39 cadavers (78 knees) were performed. MMP and LMP injection to both knees of other 39 cadavers were also performed. Accuracy rate was the highest (85%) in the AL injection portal and lowest in the MMP portal (56%). In conclusion, the accuracy obtained with use of the MMP portal was significantly lower than that obtained with the use of either the AM (P < 0.05), AL (P < 0.0001), or LMP (P < 0.05) portal. Although AL injection site resulted in good intra-articular delivery with 85% accuracy rate and with a lower incidence of soft tissue infiltration, the results were not statistically significant when compared to AM and LMP portals. Therefore, any of these three portals might be preferred depending on the experience of the physician. On the other hand, 100% accuracy could not be obtained through any portals in the study, which should be kept in mind when treating knee problems with intra-articular medications.

[The correlation between the accuracy of steroid injections and subsequent shoulder pain and function in subacromial impingement syndrome]. / Subakromiyal sikisma sendromunda steroid enjeksiyonunun dogru sekilde uygulanmasi ile omuz agrisi ve fonksiyonu arasindaki iliski.

OBJECTIVES: We assessed the relationship between proper placement of corticosteroid injections and subsequent shoulder function and pain in subacromial impingement syndrome. METHODS: The study included 48 patients (29 women, 19 men; mean age 46.5 years; range 23 to 58 years) with subacromial impingement syndrome, whose complaints of shoulder pain lasted more than two months. To monitor the site of injection, contrast material was added to a mixture of steroid and local anesthetic solution. Injections were delivered into the subacromial bursa by an anterolateral approach. Radiographs of the joint were taken immediately afterwards to ensure the accurate placement of the injection. Shoulder function and pain were evaluated by visual pain scale, range of movement of the joint, and Constant scores before treatment, and half an hour and two weeks after the injections. RESULTS: The injections were placed accurately in 42 patients (87%), while in six patients (12.5%), delivery to the target site failed. Statistically significant improvements were observed in both groups half an hour after the injections (p<0.05). However, two weeks after the treatment evaluations showed that failure to obtain an accurate placement was associated with return to pretreatment values, while significant improvement continued in the other group. CONCLUSION: Failure to deliver injections to the target site may be decreased by increased utilization of visualization and imaging methods.

Kinetics of high-heeled gait.

A within-subject comparative study of walking while wearing low-heeled sports shoes versus high-heeled dress shoes was performed to identify and describe changes in lower-extremity joint kinetics associated with wearing high-heeled shoes during level overground walking. A volunteer sample of 15 unimpaired female subjects recruited from the local community underwent quantitative measurement of sagittal and frontal plane lower-extremity joint function, including angular motion, muscular moment, power, and work. When walking in high-heeled shoes, a significant reduction in ankle plantar flexor muscle moment, power, and work occurred during the stance phase, whereas increased work was performed by the hip flexor muscles during the transition from stance to swing. In the frontal plane, increased hip and knee varus moments were present. These differences demonstrate that walking in high-heeled shoes alters lower-extremity joint kinetic function. Reduced effectiveness of the ankle plantar flexors during late stance results in a compensatory enhanced hip flexor "pull-off" that assists in limb advancement during the stance-to-swing transition. Larger muscle moments and increased work occur at the hip and knee, which may predispose long-term wearers of high-heeled shoes to musculoskeletal pain.
