Evaluation and Management of Idiopathic Unilateral Foot Drop.

BACKGROUND: In this study, our purpose is to evaluate patients who were followed by acute developing single-sided foot drop and improving with conservative management or spontaneously. METHODS: Between 2019 and 2020, 10 patients were evaluated for a unilateral weakness of the lower extremity in the form of absent dorsiflexion at the ankle joint and were given a diagnosis of foot drop without any etiological cause. Patients were followed for a period of 18 months. All patients were evaluated for acute foot drop of the affected extremity by utilizing the following diagnostic modalities, EMG, MRI lumbar spine, MRI knee, peripheral MRI neurography and non-contrast brain MRI. Each patient was evaluated for a history of Covid-19 infection over the past year. Patients with any identified cause were excluded. RESULTS: Initial evaluation of muscle strength in all patients revealed 0/5 by the MRC muscle testing grading scale. (1) In 2 patients, the muscle strength was 3/5 at the 6th month, and in the other 8 patients 4/5 at the 6th month. The muscle strength of all patients improved as 5/5 in 1 year. Six of the patients were dispensed an AFO device and nine patient's performed physical therapy. Evaluation of EMG results identified significant neuropathy at the level of the common peroneal at the fibular head in all patients. In comparison with peroneal nerve stimulation below and above the fibular head in the lateral popliteal fossa; 50% reduction in sensory amplitude, and motor conduction slowing of >10 m/s was present. Evaluation of knee MRI revealed, no masses, edema, or anatomical variations at the level of the fibular head. CONCLUSIONS: In patients diagnosed with unilateral acute foot drop without an etiological cause, one should keep in mind that spontaneous resolution of this condition can occur within one year period.

What Would be the Difference Between Operative Treatment of Patients with Tibia Fractures out of Working Hours; Intramedullary Nailing for Tibial Shaft Fractures.

Objectives: Performing orthopedic surgery in and out of working hours may affect the success of the surgery. Timing of surgery in tibial shaft fractures is controversial. In this study, the effect of the timing of surgery on the success and complications of intramedullary nailing of tibial fractures is examined. Methods: Archieves of patients with tibial shaft fractures treated with reamed intramedullary nails between 2010 and 2016 were retrospectively analyzed. Fifty-seven patients were included in the study. Patients were categorized by the time of the surgery. Day time (Group I) is between 7:00 am and 5:00 pm and after hour (Group II) is between 5:00 pm and 07:00 am. Group I (n: 40) and Group II (n: 17) were evaluated. Technical errors, surgery time, and length of hospital stay statistical analysis was performed between the two groups in terms of technical errors, complication rates, length of hospital stay, and duration of surgery. Results: The mean duration of operation (p=0.419), number of distal screws (p=0.847), time to union (p=0.454), experience of the surgeon (p=0.192), and technical error rate (p=0.654) did not differ significantly between two groups. Length of hospital stay and time to surgery from emergency were significantly higher in day time group. Conclusion: Technical errors and surgery time of intramedullary nailing of tibial shaft fractures are not higher at after hour before midnight than day time. Non-urgent tibial shaft fractures might be treated with intramedullary nailing at after hours before midnight for efficient use of hospitals.

Syndesmosis Injuries in Lateral Malleolar Fractures Accompanied by a Posterior Malleolar Fracture: A Nonfixed Posterior Fracture Fragment May Not Affect Postoperative Tibiofibular Joint Malreduction Rates.

BACKGROUND: The fact that lateral malleolar fracture is accompanied by posterior malleolar fracture may adversely affect syndesmosis malreduction rates. We aimed to compare syndesmosis malreduction rates determined on postoperative radiographs between isolated lateral malleolar fractures and lateral malleolar fractures accompanied by posterior malleolar fractures. METHODS: We retrospectively examined 128 operative patients: 73 with isolated lateral malleolar fractures (group L) and 55 with lateral + posterior malleolar fractures (group LP). In group LP, no patients received posterior fragment fixation. In both groups, indirect syndesmosis fixation was performed with a single screw after open reduction and internal fixation of the lateral malleolus. Patient age, sex, fracture side, fracture type (Lauge-Hansen and Danis-Weber classifications), Kellgren-Lawrence osteoarthritis classification, syndesmotic incongruency on postoperative radiographs, syndesmotic malreduction of postoperative fibula fracture, fracture union time, complication rates, accompanying injuries, and preoperative and postoperative radiographic syndesmotic measurements (tibiofibular overlap, tibiofibular clear space, medial clear space) were recorded, and the groups were compared. RESULTS: Mean ± SD age was 44.32 ± 15.66 years in group L and 48.93 ± 14.03 years in group LP (P = .087). There were no significant differences in preoperative and postoperative tibiofibular distance, tibiofibular overlap, and medial clear space values between groups (P > .05). The prevalence of grade 2 fractures according to the Kellgren-Lawrence classification was significantly higher in group LP (P = .047). Postoperative syndesmosis malreduction was detected in 12 patients in group L and in nine in group LP (P = .991). CONCLUSIONS: In lateral malleolar fractures accompanied by small-fragment posterolateral or avulsion-type posterior malleolar fractures, closed syndesmotic screw fixation does not cause syndesmosis malreduction.

Distal metatarsal osteotomy and dorsal neutralization plate in the treatment of hallux valgus.

PURPOSE: Hallux valgus is a disease that can be treated with many different surgical procedures. In our study, we aimed to compare patients with and without dorsal neutralization plate after distal metatarsal osteotomy and fixation with compression screws. METHODS: The files of 59 patients with 89 feet operated with the diagnosis of moderate degree hallux valgus have been examined retrospectively. Hallux valgus angles, AOFAS, VAS and satisfaction scores, time to return to work of both groups were compared. The cases in which only screw fixation was performed were mobilized with the hallux valgus apparatus for 6 weeks postoperatively, while the cases in which dorsal neutralization plate was performed were immediately mobilized full weightbearing without using an additional apparatus. Patients with a minimum follow-up of 2 years were included in the study. RESULT: There was no statistically significant difference between the two groups in terms of being bilateral (p = 0.457), mean age (p = 0.105) and gender data (p = 0.105). There was no significant difference in the preop and postop second year hallux valgus angles, AOFAS, VAS and satisfaction scores of the patients. There was a significant difference in the time to return to work (p < 0.001) and the 6th week AOFAS (p < 0.001), VAS (p < 0.001) and postop satisfaction (p < 0.001) scores between the two groups. CONCLUSION: The dorsal neutralization plate performed in addition to the compression screw after distal metatarsal osteotomy can cause painless early postoperative results that do not require the use of an additional apparatus, and early good functional results.

The Effect of Syndesmotic Screw Level on Postoperative Syndesmosis Malreduction.

Tibiofibular injury repair of ankle fractures may result in over-compression when performed via a partially threaded screw depending on its placed level. We aimed to examine the relationship between the screw level relative to the tibiotalar joint and syndesmosis malreduction in postoperative radiographs of ankle fractures treated with partially threaded screws. We retrospectively analyzed 129 patients who underwent surgery due to lateral malleolar fractures between 2011 and 2019. We measured the distance between the screw and the tibiotalar joint and stratified the patients per their screw level as either trans-syndesmotic or suprasyndesmotic. According to Lauge-Hansen, 83 cases were supination-external rotation type (64.3%), and the remaining were pronation-external rotation type (35.7%) injuries. We found postoperative syndesmosis malreduction in 20 cases (15.5%). Eight (6.2%) cases had medial clear space mismatch. As the distance of the screw to the joint increased, postoperative medial clear space values increased (rho: 0.190, p = .031). The relationship between postoperative syndesmosis mismatch and the level of the syndesmotic screw was statistically significant (p = .044). In syndesmosis repair with a partially threaded screw, as the distance of the screw from the joint increases, the over-compression caused by the screw may cause an increase in postoperative syndesmotic malreduction rates.

High Varus Angle and Lower Posterior Tibial Slope Associated with PCL Injury in Cruciate Retaining Total Knee Arthroplasty: An MRI Study.

The posterior tibial slope (PTS) is important for performing a tibial cut that does not injure the posterior cruciate ligament (PCL). In this study, the amount of PCL fibers sacrificed under simulated tibial cuts with varying posterior inclinations was evaluated using magnetic resonance images (MRIs) of osteoarthritic varus knees. Knee X-rays, orthoroentgenograms, and MRIs of 113 Kellgren and Lawrence grades 3 to 4 osteoarthritic knees were included. Four different simulated tibial cuts were performed at 0, 3, 5 degrees and parallel to the tibia plateau 3 mm below of the most defective part of the cartilage in the medial plateau. Correlations between the PCL avulsion amount and the PTS and varus alignment of the lower extremity were analyzed for all four simulated tibial cut levels. The maximum amount of PCL was preserved with a 0-degree tibial cut in patients with a PTS of more than 8 degrees. With increased tibial cut angles, the posterior slope resulted in an increased amount of avulsed PCL. Although the amount of avulsed PCL was proportional with the varus alignment, it was inversely proportional with the sagittal slope. The number of injured PCLs also increased as the slope of the tibial cuts increased. Patients with mild varus alignments and high PTSs are more suitable for cruciate retaining total knee arthroplasty.

Arthroscopy-assisted versus standard intramedullary nail fixation in diaphyseal fractures of the humerus.

PURPOSE: The aim of this study was to assess applicability of arthroscopic technique in intramedullary nail fixation of humerus shaft fractures and to compare with conventional nailing in terms of its effects on perioperative and postoperative intra-articular complication rates as well as on clinical and functional outcomes. METHODS: This prospective randomized controlled clinical trial included 40 patients (12 females and 28 males) indicated for surgery between either undergo arthroscopy-assisted (Arthroscopy-assisted intramedullary nailing [AIMN]; n = 20) or conventional (Intramedullary nailing [IMN]; n = 20) anterograde intramedullary nailing. Two groups were compared in terms of mean number of fluoroscopic shootings until the guide wire was inserted, time for union, length of hospital stay, and complication rates. Shoulder functions were assessed by Constant and American Shoulder and Elbow Surgeons (ASES) score. RESULTS: Groups did not significantly differ in terms of age, gender, and mechanism of injury, length of hospital stay, union rate, and mean union time ( p > 0.05). Mean ASES and Constant scores were found to be statistically significantly higher in AIMN group than that in IMN group ( p = 0.000 and p = 0.002, respectively). Mean number of fluoroscopic shootings until the guide wire was inserted was 2.15 in AIMN group, which was significantly lower compared to 4.2 of IMN group ( p = 0.000). CONCLUSIONS: Arthroscopy-assisted technique may be an applicable and safe method owing to its cosmetic advantages and more satisfactory postoperative shoulder functions subsequent to less injury to deltoid, rotator cuff, and other soft tissue, as compared to conventional anterograde approach.

Lower numbers of mechanoreceptors in the posterior cruciate ligament and anterior capsule of the osteoarthritic knees.

PURPOSE: Impaired proprioception accuracy of the knee has been proposed as a local factor in the onset and progression of knee osteoarthritis. Patients with decreased numbers of mechanoreceptors could be more likely to develop arthrosis due to a loss in proprioception of the joint. We aimed to identify and quantify the mechanoreceptors of the posterior cruciate ligament (PCL), the anterior capsule (AC) and the medial meniscocapsular junction (MCJ) in knee arthrosis. METHODS: PCLs, ACs and MCJs were harvested from 30 patients with Kellgren and Lawrence grades 3 and 4 osteoarthritis (OA), and ten knees taken from five cadavers without OA were used as a control group. PCL degeneration was evaluated with haematoxylin & eosin, and the types and numbers of mechanoreceptors were evaluated using S100 immunostaining. RESULTS: The patient ages in the OA and control groups (n.s.) did not differ. PCL degeneration was more severe in the gonarthrosis group than in the control group (p = 0.04). The numbers of Golgi corpuscles, Ruffini corpuscles, free nerve endings, total nerve endings and small vessels of the PCL were low in the OA group, as were the numbers of Golgi corpuscles, free nerve endings and total nerve endings of the AC. No significant correlation was found regarding the mechanoreceptors of the MCJ between the two groups. CONCLUSION: The numbers of mechanoreceptors in patients with OA were low in the PCLs and ACs. A loss in proprioception could be a local risk factor in OA. The proprioceptive impact of preserving PCL while performing total knee arthroplasty may not be exaggerated as its thought. LEVEL OF EVIDENCE: Prognostic study, Level I.

Anterograde Headless Cannulated Screw Fixation in the Treatment of Medial Malleolar Fractures: Evaluation of a New Technique and Its Outcomes.

OBJECTIVE: To evaluate the functional and radiological outcomes of anterograde headless cannulated screw fixation for medial malleolar fractures. SUBJECTS AND METHODS: This study included 12 patients (8 males, 4 females; age 27-55 years) with medial malleolar type B fractures according to the Herscovici fracture classification who had undergone anterograde headless cannulated screw fixation surgery between 2012 and 2014. Seven had an isolated medial malleolar fracture and 5 a bimalleolar fracture. All of the bimalleolar fractures were classified as 44-B2 based on the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) classification. Postoperatively, bone union was evaluated on direct radiographs at the final follow-up examination. The American Orthopaedic Foot and Ankle Society (AOFAS) scoring system was used for clinical evaluation. RESULTS: The mean follow-up period was 17.2 ± 5.3 months (range 12-23). Full union was achieved in all fractures. The mean time to union was 3.4 ± 1.5 months (range 2-5). No instability, loss of reduction, non-union or infection was observed in any patient. The mean AOFAS score was 95.0 ± 5.4 (range 87-99). Based on the AOFAS score, 4 patients showed good results and 8 excellent results. The mean time to return to the previous level of activity was 4.0 ± 2.5 months (range 2-5). CONCLUSION: In this study, anterograde headless cannulated screw fixation yielded good clinical outcome in the surgical treatment of Herscovici type B fractures.

The results of bone deformity correction using a spider frame with web-based software for lower extremity long bone deformities.

AIM: To present the functional and radiological results and evaluate the effectiveness of a computer-assisted external fixator (spider frame) in patients with lower extremity shortness and deformity. MATERIALS AND METHODS: The study comprised 17 patients (14 male, 3 female) who were treated for lower extremity long bone deformity and shortness between 2012 and 2015 using a spider frame. The procedure's level of difficulty was determined preoperatively using the Paley Scale. Postoperatively, the results for the patients who underwent tibial operations were evaluated using the Paley criteria modified by ASAMI, and the results for the patients who underwent femoral operations were evaluated according to the Paley scoring system. The evaluations were made by calculating the External Fixator and Distraction indexes. RESULTS: The mean age of the patients was 24.58 years (range, 5-51 years). The spider frame was applied to the femur in 10 patients and to the tibia in seven. The mean follow-up period was 15 months (range, 6-31 months) from the operation day, and the mean amount of lengthening was 3.0 cm (range, 1-6 cm). The mean duration of fixator application was 202.7 days (range, 104-300 days). The mean External Fixator Index was 98 days/cm (range, 42-265 days/cm). The mean Distraction Index was 10.49 days/cm (range, 10-14 days/cm). CONCLUSION: The computer-assisted external fixator system (spider frame) achieves single-stage correction in cases of both deformity and shortness. The system can be applied easily, and because of its high-tech software, it offers the possibility of postoperative treatment of the deformity.

Inferior hip dislocation after falling from height: A case report.

INTRODUCTION: Traumatic inferior hip dislocation is the least common of all hip dislocations. Adult inferior hip dislocations usually occur after high-energy trauma, very few cases are reported without fracture. PRESENTATION OF CASE: A 26-year-old female was brought to the emergency department with severe pain in the left hip, impaired posture and restricted movement following a fall from 15m height. The hip joint was fixed in 90° flexion, 15° abduction, and 20° external rotation. No neurovascular impairment was determined. On radiologic examination, a left ischial type inferior hip dislocation was detected. Hemorrhagic shock which developed due to acute blood loss to thoracic and abdominal cavity and patient died at third hour after she was brought to the hospital. DISCUSSION: Traumatic hip dislocations have high morbidity and mortality rates due to multiple organ damage, primarily of the extremities, chest and abdomen. In the treatment of traumatic hip dislocation, closed reduction is recommended through muscle relaxation under general anesthesia or sedation. This procedure should be applied before any intervention for concomitant extremity injuries. A detailed evaluation on emergency presentation, a multi-disciplinary approach and early diagnosis with the rapid application of imaging methods could be life-saving for such patients.

An evaluation of meniscus tears in lateral tibial plateau fractures and repair results.

BACKGROUND: Soft tissue injuries may co-occur with tibial plateau fractures. These injuries may include medial or lateral ligament ruptures, peroneal nerve lesions, anterior cruciate ligament ruptures, and meniscus tears. OBJECTIVE: The aim of this study was to investigate the frequency of meniscus tears in lateral tibial plateau fractures and to evaluate the clinical and radiological results of meniscus repairs. MATERIALS AND METHOD: The study included 19 patients who underwent surgery for a closed lateral tibial plateau fracture. Anteroposterior and lateral radiographs of the knee, followed by magnetic resonance imaging (MRI) examinations, were undertaken for all cases. The clinical and radiological evaluation of the surgical treatment results was performed according to the Rasmussen criteria. RESULTS: Meniscus lesions were found in 10 (52.6%) patients. Nine meniscus tears were found in patients with type 2 fractures, and one meniscus tear was found in a patient with a type 3 fracture. All of the menisci were separated from the peripheral capsule adhesion point. On the MRI examination during follow-up, all of the repaired lateral menisci were determined to be in their original anatomic location. CONCLUSION: For successful outcomes in lateral plateau fractures, it is essential to determine whether there is a meniscus tear. In cases with meniscus tears, meniscus repair can be easily performed and should be considered because it has a positive impact on the treatment outcome.

Effects of the lower extremity external fixators on the sexual life of males.

OBJECTIVE: In tibial fractures, the use of an external fixator (EF) may be associated with sexual dysfunction (SD) in sexually active male patients. We aimed to investigate the influence of EF applied for tibial fracture on the sexual life in male patients. METHODS: We retrospectively evaluated 137 male patients who presented with tibial fractures and underwent surgical intervention with unilateral or circular EF. The patients completed the Brief Sexual Function Inventory (BSFI) form during the interview. We evaluated the incidence of the development of SD and the severity of SD with the use of an EF, and the relation with the type of EF and SD was investigated. The responses were compared with the results of the completed BSFI forms of 119 male patients who were treated with internal fixation (IF) for tibial fractures. RESULTS: In total, 108 patients (mean age, 42.8 years) treated with EF accepted the invitation and filled the form. The score of those patients were worse compared with that of the patients who were treated with IF (p<0.001). Postoperative sexual functions were the same with the preoperative sexual function in 12 patients (11%). However, the postoperative scores were decreased in 96 (89%) patients, which meant that the sexual functioning was impaired. None of the patients reported persistent SD. CONCLUSION: EF in the cruris may impair sexual functions in males. The rate of SD was higher in male patients who were treated with EF. Thus, SD might be associated with physical, psychological, and social limitations caused by EF.

Outcome of Type 3 Open Tibial Diaphyseal Fractures Managed with a Limb Reconstruction System: Analysis of a 49-Patient Cohort.

OBJECTIVE: To evaluate functional and radiological results following treatment with the single-plane external fixator limb reconstruction system (LRS) for open tibial diaphyseal fractures resulting from high-energy trauma. SUBJECTS AND METHODS: From a total of 62 patients who were operated on between 2011 and 2014 for open tibial diaphyseal fractures resulting from high-energy trauma, 50 tibias from 49 patients (males: 32, females: 17) were classified as type 3 according to the Gustilo-Anderson open fracture classification, and definitive treatment was applied with the LRS. The patients ranged in age from 20 to 36 years. Time to union, time of external fixator usage, complications and functional results according to the Johner-Wruhs criteria were recorded. RESULTS: The mean follow-up period was 23 ± 12 months (range: 11-44). Of the 50 tibias, full union was achieved with the LRS in 48 (96%). No shortness or deformity was observed in any patient. Knee and ankle range of movement were measured as full in all patients at the final follow-up examination after removal of the LRS. The mean time to union was 20.4 ± 4 weeks (range: 16-24). The mean time of external fixator use was 20 weeks (range: 16-24 weeks). CONCLUSION: In this study, for the definitive treatment of open tibia diaphyseal fractures, the LRS was an optimal and safe choice that offered single-stage surgery.

Measurement of the knee joint line in Turkish population.

OBJECTIVE: The aim of the present study was to determine the knee joint line level by its distance to the adductor tubercle and the apex of the fibular head in the Turkish population. METHODS: The study included 117 knees of 108 patients (63 males, 45 females; mean age: 31.3 years, range: 16 to 82 years). Femoral width and the distance from the apex of the fibular head to the joint line as well as the distance from the adductor tubercle to the joint line were measured on anteroposterior radiographs. RESULTS: Mean femoral width was 87.2 mm. The average distance from the adductor tubercle to the joint line was 47.9 mm and from the fibular head to the joint line was 20.5 mm. A linear correlation was found between the distance from the adductor tubercle to the joint line and femoral width, with a ratio of 0.55. There was no significant correlation between the distance from the fibular head to the joint line and femoral width. CONCLUSION: There was a linear correlation between the femoral width and the adductor tubercle-joint line distance irrespective of any factors such as age, gender and height. Therefore, the adductor tubercle can be used as a reliable landmark to determine the joint line level for easy evaluation and measurement during surgery.

Osteoid osteoma treated with radiofrequency ablation.

Purpose. Our aim is to evaluate the results of treatment with computed tomography (CT) guided percutaneous radiofrequency ablation for osteoid osteomas which were localized in a difficult area for operation. Materials and Methods. Glenoid, distal tibia, humerus shaft, proximal humerus, and in third finger of the hand proximal phalanx were involved in one patient. Proximal femur was involved in three patients, distal femur was involved in three patients, and proximal tibia was involved in two patients. 9 males and 4 females were aged 4 to 34 years (mean age: 18.5 years). All patients had pain and were evaluated with X-rays, CT, bone scintigraphy, and MRI. In all patients, RF ablation was performed with local anesthesia. The lesion heated to 90°C for 6 minutes. Results. All of the patients achieved complete pain relief after ablation and were fully weight bearing without any support. In all patients, there was soft tissue edema after the procedure. During follow-up, all patients were free from the pain and there was no sign about the tumor. There was no other complication after the process. Conclusion. CT guided RFA is a minimally invasive, safe, and cost-effective treatment for osteoid osteoma placed in difficult area for surgery.

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.

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.

[Arthroscopic rotator cuff repair: evaluation of outcomes and analysis of prognostic factors]. / Artroskopik rotator manset onarimi: Sonuçlar ve belirleyici faktörlerin analizi.

OBJECTIVES: The purpose of this study was to evaluate the results of arthroscopic rotator cuff repair of full-thickness tears and to determine prognostic factors. METHODS: Forty-one shoulders of 40 patients (16 males, 24 females; mean age 56 years; range 39 to 72 years) unresponsive to conservative treatment were evaluated. The mean symptom duration was 15 months (range 2 to 24 months). Involvement was on the right in 34 shoulders, on the left in seven shoulders, 80% being on the dominant side. The range of motion was measured with a goniometer, muscle strength was measured manually. Clinical and functional evaluations were based on physical and radiological examinations, and the UCLA scale. The mean follow-up was 37 months (range 12 to 61 months). Prognostic factors included age, symptom duration, range of motion, muscle strength, tear size, retraction and quality of tendon, and fatty degenerative changes. RESULTS: According to the UCLA scale, the results were satisfactory in 29 shoulders (70.7%), moderate in five (12.2%), and poor in seven (17.1%). Six shoulders (14.6%) required revision surgery. Postoperative improvements in forward flexion and muscle strength were significant (p<0.05), whereas change in external rotation was insignificant (p>0.05). Age, tear size, retraction and quality of tendon, and fatty degenerative changes were found to significantly affect unsatisfactory results (p<0.05). Preoperative symptom duration, range of motion, and muscle strength were not effective on the results (p>0.05). CONCLUSION: Our results are not as successful as those obtained from open procedures. The results may be more satisfactory through improving arthroscopic skills and taking prognostic factors into consideration in patient selection.
