Delayed presentation of gluteal compartment syndrome presenting with peroneal palsy secondary to superior gluteal artery pseudoaneurysm following ballistic injury.

Gluteal compartment syndrome (CS) secondary to the superior gluteal artery (SGA) injury and pseudoaneurysm formation is a very rare condition. When it does occur, it usually manifests with acute and life-threatening hemorrhage resulting in early hypov-olemic changes. Delayed presentation of the gluteal CS (GCS) after trauma has been described in the literature seldom and these cases were demonstrated with sciatic nerve palsy, hemodynamic instability, decreased hemoglobin levels, increasing buttock pain, and a large gluteal hematoma. In this report, we present a case of GCS presenting with the palsy of the peroneal division of the sciatic nerve secondary to SGA pseudoaneurysm following ballistic injury, with a delay of nearly 20 days in diagnosis and treatment with normal hemodynamic findings. The patient required emergent angiographic embolization and then fasciotomy which were approx-imately 13 days after the onset of the symptoms. The patient made a positive recovery with no further neurologic deterioration and none local wound or systemic complications. This case emphasizes the importance of early diagnosis and treatment of this rare condition.

Direct Anterior Approach Versus Posterolateral Approach for Hemiarthroplasty in the Treatment of Displaced Femoral Neck Fractures in Geriatric Patients.

BACKGROUND In the present study, we aimed to evaluate early clinical and biochemical outcomes of direct anterior approach (DAA) versus posterolateral approach (PLA) for hemiarthroplasty in the treatment of displaced femoral neck fractures in geriatric patients. MATERIAL AND METHODS Between September 2012 and September 2017, a total of 110 patients who underwent hemiarthroplasty for displaced femoral neck fractures were retrospectively analyzed. The patients were divided into 2 groups according to the surgical technique PLA (Group 1, n=54) and DAA (Group 2, n=56). Clinical and biochemical results were compared. RESULTS There was no significant difference in the demographic characteristics of the patients, fixation type, and follow-up (P>0.05). However, there was a significant difference in the duration of surgery, amount of blood transfusion, change from baseline in postoperative hemoglobin levels, amount of intraoperative gauze dressing, amount of drainage fluid from the surgical wound, postoperative VAS scores, incision length, length of hospital stay, and Barthel Index scores in favor of DAA group (P<0.05). There was no significant difference in the degree of mobilization (P>0.05). None of the patients had postoperative complications in Group 1, while 3 patients in Group 2 developed a lateral femoral cutaneous nerve lesion and one patient had a missed iatrogenic fracture of the greater trochanter. CONCLUSIONS Our study results suggest that early clinical and biochemical outcomes are better in DAA than PLA with early return to daily living activities in patients undergoing hemiarthroplasty for displaced femoral neck fractures.

Total hip arthroplasty with rectangular stems and subtrochanteric transverse shortening osteotomy in Crowe type IV hips: a retrospective study.

BACKGROUND: The complexity of femoral and acetabular anatomy and restoring anatomic center of hip rotation in Crowe type IV developmental dysplasia of the hip (DDH) complicates standard reconstruction. The aim of this study is to evaluate surgical techniques and clinical outcomes of subtrochanteric transverse shortening osteotomy with the use of cementless rectangular cross-section femoral implants in Crowe IV dysplastic hips. METHODS: A total of 26 hips of 25 consecutive patients with Crowe type IV DDH who underwent cementless total hip arthroplasty with subtrochanteric femoral transverse shortening osteotomy were retrospectively analyzed. The Harris Hip Score, Visual Analog Scale-pain, leg length discrepancy, and vertical and lateral migration of hip rotation center were recorded. RESULTS: Mean age, follow-up, and time of union were 41 ± 9.7 years, 7.1 ± 1.2 years, and 3.7 ± 1.1 months, respectively. Mean Harris Hip Score significantly improved from 38 ± 5.7 to 86 ± 6.1 points postoperatively (P < .01). Mean leg length discrepancy and Visual Analog Scale significantly decreased from 4.3 ± 1.3 to 1.2 ± 0.6 cm, and 6.4 ± 1.2 to 1.8 ± 0.8 points, respectively (P < .01). One female patient had a dislocation due to acetabular liner wear, which was managed by liner and head change. One patient had Sudeck's atrophy, while another had pain on the lateral thigh, both of which were resolved with conservative management. CONCLUSIONS: Combined transverse subtrochanteric femoral osteotomy and cementless total hip arthroplasty with rectangular cross-section femoral implants is technically demanding, effective, and safe in femoral shortening for treatment of Crowe type IV DDH.

Treatment of implant-related methicillin-resistant Staphylococcus aureus osteomyelitis with vancomycin-loaded VK100 silicone cement: An experimental study in rats.

INTRODUCTION: The purpose of this present study is to investigate the efficacy of vancomycin-loaded VK100 silicone cement drug delivery system in the treatment of implant-related methicillin-resistant Staphylococcus aureus (MRSA) osteomyelitis in rats. MATERIALS AND METHODS: Thirty-six adult (18-20 weeks old) female Sprague-Dawley rats were included in the study. All rats underwent experimental osteomyelitis surgery via injecting 100 µL bacterial suspension of MRSA into the medullary canal. After a 2-week duration for the formation of osteomyelitis model, rats were assigned randomly into four groups: control (C), systemic vancomycin (V), local vancomycin-loaded VK100 silicone cement (vVK100), and systemic vancomycin and local vancomycin-loaded VK100 silicone cement (V+vVK100). The following treatment protocols were administered to each group for 4 weeks. For group C, 0.9% saline solution equivalent to the volume of vancomycin dose (approximately 1 ml/kg) was administered intraperitoneally twice daily (12-h intervals). For group V, 15 mg/kg of vancomycin was administered intraperitoneally twice daily (12-h intervals). For group vVK100, vVK100 polymer was included so that the intramedullary canal of the rats are affected. For group V+vVK100, vVK100 polymer was included so that the intramedullary canal of the rats are affected and 15 mg/kg of vancomycin was administered intraperitoneally twice daily (12-h intervals). After 4 weeks of treatment, clinical, radiologic, microbiologic, and histopathologic evaluations were performed for all groups. RESULTS: Results of this study revealed that all scores of the evaluation criteria for the treatment groups (groups V, vVK100, and V+vVK100) decreased due to the treatment protocols when compared to group C. These results show the effectiveness of all treatment protocols for the implant-related chronic MRSA osteomyelitis. However, there were no statistical difference between these three protocols. CONCLUSIONS: vVK100 polymer, as a local antibiotic delivery system, seems to be an effective method for the treatment of implant-related chronic MRSA osteomyelitis.

[Severe cartilage loss caused by metallic anchors in surgical treatment of a Bankart lesion: report of three cases]. / Bankart lezyonunun cerrahi tedavisinde metalik kancalara bagli gelisen ciddi kikirdak kaybi: Üç olgu sunumu.

Currently, arthroscopic modalities in the surgical treatment of shoulder instability using suture anchors are more popular than open surgery. However, there are some complications related to the metallic suture anchors used. One of the most common complications is cartilage loss due to shallow placement of the suture anchor. Herein, we report three cases with severe cartilage loss of the humeral head due to metallic proud anchors, including one of whom requiring total shoulder arthroplasty. In conclusion, it is essential to place the suture anchors in an appropriate position and deepness. In case of any doubt, they should be removed or in non-threaded anchors, they should be inserted fully inside the glenoid with an impactor and a hammer to avoid serious cartilage loss.

Turkish Version of Kolcaba's Immobilization Comfort Questionnaire: A Validity and Reliability Study.

PURPOSE: The purpose of this study was to determine the validity and reliability of the Turkish version of the Immobilization Comfort Questionnaire (ICQ). METHODS: The sample used in this methodological study consisted of 121 patients undergoing lower extremity arthroscopy in a training and research hospital. The validity study of the questionnaire assessed language validity, structural validity and criterion validity. Structural validity was evaluated via exploratory factor analysis. Criterion validity was evaluated by assessing the correlation between the visual analog scale (VAS) scores (i.e., the comfort and pain VAS scores) and the ICQ scores using Spearman's correlation test. The Kaiser-Meyer-Olkin coefficient and Bartlett's test of sphericity were used to determine the suitability of the data for factor analysis. Internal consistency was evaluated to determine reliability. The data were analyzed with SPSS version 15.00 for Windows. Descriptive statistics were presented as frequencies, percentages, means and standard deviations. A p value ≤ .05 was considered statistically significant. RESULTS: A moderate positive correlation was found between the ICQ scores and the VAS comfort scores; a moderate negative correlation was found between the ICQ and the VAS pain measures in the criterion validity analysis. Cronbach α values of .75 and .82 were found for the first and second measurements, respectively. CONCLUSIONS: The findings of this study reveal that the ICQ is a valid and reliable tool for assessing the comfort of patients in Turkey who are immobilized because of lower extremity orthopedic problems.

The accuracy of two different extra-medullary tibial cutting guides for posterior tibial slope in total knee arthroplasty.

OBJECTIVES: This study aims to evaluate the effectiveness of two different external tibial cutting guides with and without a spike anchoring to the intercondylar eminentia to achieve a desired posterior tibial slope. PATIENTS AND METHODS: Between January 2008 and December 2011, 120 posterior cruciate ligament protecting total knee arthroplasty (TKA) surgeries of 83 patients in which two different external tibial cutting guides used were included. Fifty-nine knees were included into the spiked and 61 knees were included into the spikeless cutting guide group. Posterior tibial slope angles were measured using the postoperative X-rays. RESULTS: There was no significant difference between two groups in terms of age, sex, and body mass indexes (p<0.05). While the mean postoperative slope angle was 2.66°±2.001°(range 0°-7°) in spiked group, it was 2.46°±2.277° (range 0°-7°) in spikeless group. Both systems had identical accuracy, indicating a low rate. The comparison of variances of two groups showed that both cutting guides had similar precision (p=0.234). There was no effect of body mass index on the results in both groups. CONCLUSION: Although different extra-medullary tibial cutting guides with and without a spike can reproducibly impart a desired posterior tibial slope in TKA, we concluded that a spiked guide was considered user-friendly.

Prediction of the presence of plantaris tendon through examination of palmaris longus tendon: is there a link? / Predicción de la presencia del tendón del músculo plantar mediante el examen del tendón del músculo palmar largo: ¿hay una relación?

The purpose of this study was to investigate the relationship between palmaris longus (PL) and plantaris (P) tendons and test the clinical usefulness of symmetry patterns between these tendons in Turkish population. This prospective study comprised a total of 240 adult patients (120 men and 120 women) who were admitted to our outpatient clinic with bilateral knee complaints that required bilateral knee MR examination during two years. Standard test (Schaefer's test, oppose the thumb to the little finger while flexing the wrist) was used to assess the presence of the PL tendon both with inspection and palpation. Knee MRI was used to determine the presence of P muscle belly on both sides. We have analyzed symmetric distribution pattern using Mc-Nemar test. The PL was absent unilaterally in 34 subjects (14.2%), while it was absent bilaterally in 17 subjects (7.1%). The P was absent unilaterally in 51 subjects (21.3%), while it was absent bilaterally in 10 subjects (4.2%). If PL was absent in one hand, the chance of having an ipsilateral P tendon was 70.6%. If PL was present in one hand, the chance of having an ipsilateral P tendon was 87.6%. The Mc-Nemar test for symmetry yielded a p value of 0.841 for ipsilateral PL and P muscles. A clear-cut link between Palmaris longus and plantaris tendons could not be demonstrated in this study. Both muscles show different variations independent from each other.

El propósito de este estudio fue investigar la relación entre los tendones del músculo palmar largo (MPL ) y músculo plantar (MP) y poner a prueba la utilidad clínica de los patrones de simetría entre estos tendones de la población turca. Estudio prospectivo realizado sobre 240 pacientes adultos (120 hombres y 120 mujeres) que ingresaron en la clínica por síntomas de dolor en la rodilla bilateralmente, quienes requerían un examen de RM de rodilla durante dos años. Se utilizó la prueba estándar (prueba de Schaefer, se oponen el pulgar hasta el dedo mínimo, mientras se flexiona la muñeca) para evaluar la presencia del tendón MPL tanto con la inspección y palpación. La RM de la rodilla se utilizó para determinar la presencia de vientre muscular plantar en ambos lados. Se analizó el patrón de distribución simétrica mediante la prueba de McNemar. El tendón del MPL estuvo ausente de manera unilateral en 34 pacientes (14,2%) y bilateralmente en 17 pacientes (7,1%). El tendón del MP estuvo ausente de manera unilateral en 51 pacientes ( 21,3 %) mientras que bilateralmente no estaba en 10 pacientes (4,2%). Si el tendón del MPL estuvo ausente en un lado, la probabilidad de tener un tendón del MP ipsilateral fue del 70,6 %. Si el tendón del MPL estaba presente en un lado, la probabilidad de tener un tendón del MP ipsilateral fue 87,6%. La prueba de McNemar - simetría produjo un valor p de 0,841 para los músculos PL y P ipsilaterales. Una relación directa claro entre los tendones de los músculos PL y P no se pudo demostrar en este estudio. Ambos músculos muestran diferentes variaciones independiente uno del otro.

The relation between the arthroscopic findings and functional outcomes in patients with septic arthritis of the knee joint, treated with arthroscopic debridement and irrigation.

OBJECTIVES: The aim of this study was to evaluate the relation between arthroscopic findings and functional outcomes in patients with septic arthritis of the knee joint, treated with arthroscopic debridement and irrigation. METHODS: Twenty patients (17 male, 3 female; mean age: 31 years [5-63 years]) with knee septic arthritis treated with arthroscopic debridement and irrigation in our clinic between 2004-2007 were included in the study. The decision for arthroscopic debridement was made based on the clinical findings, erythrocyte sedimentation rate, C-reactive protein level and the aspiration of the affected knee. During the arthroscopic debridement, the joint was staged according to Gachter criteria. Continuous irrigation system was set up for all cases following surgery. After the surgery, the Bussiere functional scale was used for clinical evaluation. The mean follow-up periodwas 29±11months (range 13-54 months). The McNemar test was used in comparing the results. The Spearman correlation coefficient was used in the correlation analysis. The level of significance was set at 0.05. RESULTS: The culture was positive in 3 cases, and negative in 8 cases who exhibited gram (+) cocci in gram stains. In nine cases, cultures were negative and no microorganisms were detected in gram stains. According to the arthroscopic Gachter classification, 4 cases (20%) were Stage 1, 10 cases (50%) were Stage 2, 5 cases (25%) Stage 3 and 1 case (5%) was Stage 4. There was a statistically significant difference between the mean functional score of the knees with differing Gachter stages (McNemar test, p=0.003). There was a statistically significant and strong correlation between Gachter score and functional results (correlation coefficient: 0.780; p<0.001). CONCLUSION: Advanced arthroscopic findings are associated with poor functional results in patients with septic arthritis of the knee joint. In addition, the time between the initial symptoms and the surgery directly affects the functional results.

An uncommon presentation of malignant fibrous histiocytoma of the calcaneus.

Malignant fibrous histiocytoma of bone is the osseous counterpart of the tumor in soft tissue. It is a rare primary bone tumor, and there have been conflicting reports on its grades of malignancy. The appendicular skeleton, especially the femur, is the most common site of involvement, whereas the calcaneus is rarely involved. We describe a primary malignant fibrous histiocytoma of the calcaneal bone in a 21-year-old man. The patient underwent neoadjuvant and adjuvant chemotherapy and below-the-knee amputation, and no local recurrence or metastasis was noted after 2 years of follow-up.

Coccygectomy in the surgical treatment of traumatic coccygodynia.

THE PURPOSE OF THE STUDY: Direct or indirect trauma to the coccygeal bone can induce chronic coccygodynia. The aim of this study is a retrospective analysis of our patients surgically managed for traumatic coccygodynia and a critical review of the results obtained in comparison to the literature. BASIC PROCEDURES: We have retrospectively investigated patients with traumatic coccygodynia referred to our centre after a failure of conservative treatment. Surgery (coccygectomy) was performed in 74 patients (64 women, 10 men) suffering from coccygodynia resistant to conservative treatment, all without serious complications, between the years 1998 and 2004. The mean follow up was 4.1 years (range, 2-8 years). The mean age of patients on the date of surgery was 43.4 years (range, 16-65 years). The average duration of pain prior to surgery was 7 months (range, 3 months to one year). MAIN FINDINGS: All but three patients had either good or excellent results after surgery. Three patients reported postoperative pain lasting 3-6 months. All three had good results after re-operation of a proximal segment without excision. Five postoperative complications, four superficial and one deep infection were observed. PRINCIPAL CONCLUSIONS: In patients with posttraumatic, conservative therapy-resistant coccygodynia, operative treatment with coccygectomy is a feasible management option. We recommend total or partial coccygectomy using a longitudinal incision in carefully selected and well-informed patients.

[The relationship between phantom limb pain and neuroma]. / Fantom ekstremite agrisi ile nörinom olusumu arasindaki iliski.

OBJECTIVES: We evaluated the effect of exploratory neurectomy on phantom limb pain (PLP) in patients who had PLP and neuroma findings in the amputated extremity. METHODS: The study included 14 patients (13 males, 1 female; mean age 30 years; range 21 to 54 years) who developed symptomatic neurinoma and PLP following amputation of an extremity due to trauma (9 mine blasts, 5 traffic accidents). Postamputation period ranged from 2.5 to 17 years (mean 5.5 years). All the patients had PLP of varying intensity and neuroma symptoms causing the sensation of a small electric shock, aroused by application of prosthesis, contact with bed, or on palpation. The mean visual analog scale (VAS) score for PLP was 8.4 (range 7 to 10) before neurectomy. The mean follow-up was 71.5 months (range 44 to 98 months). RESULTS: Complete recovery from PLP was achieved after neurectomy. Symptoms of neuroma completely disappeared during the follow-up period. Visual analog scale score was 0 in all the patients. CONCLUSION: The best way to prevent postamputation neuromas and PLP is to cut the nerve as proximal as possible, allowing its retraction into the soft tissue, and leaving its end away from the stump.

Modified crescentic proximal metatarsal osteotomy and distal soft tissue procedures in hallux valgus.

The results of a modified crescentic proximal metatarsal osteotomy and distal soft tissue procedures for patients with symptomatic, incongruent, metatarsophalangeal joint, hallux valgus deformity were reviewed. Forty-nine feet of 41 patients were evaluated. All of the patients were male military personnel of different ranks, and their mean age was 23 years (range, 20-43 years). The mean follow-up period was 25 months (range, 10-60 months). The patients were evaluated according to the American Orthopedic Foot and Ankle Society forefoot scoring system. The mean preoperative score was 54.4, and the mean postoperative score was 95.4. The mean hallux valgus angle was 39.4 degrees before surgery and 12.8 degrees after surgery (26.6 degrees correction); the mean intermetatarsal angle was 15.9 degrees before surgery and 7.1 after surgery (8.8 degrees correction). A total of 93.8% of the patients were satisfied with the results of the procedure. Complications included delayed union in one case and superficial wound infections in two cases. We also emphasize small modifications performed while shifting the metatarsal shaft laterally and compare the results of our study with those of similar studies.
