Precise placement of lag screws in operative treatment of trochanteric femoral fractures with a new guide system

PURPOSE We assessed the accuracy of a new guide system that we developed to place lag screws in the proper position with the minimum number of attempts for operative treatment of trochanteric femoral fractures. METHODS A total of 55 consecutive trochanteric femoral fractures were treated with a cephalomedullary nail. The first 27 consecutive patients were treated with the standard operation (group A), while the new guide system was used in the last 28 consecutive patients (group B). The numbers of attempts to place K wires and the duration of surgery were noted. Accuracy of lag screw placement was evaluated by measuring the angle of deviation from the central axis of the femoral head. RESULTS Deviation values ranged from -11̊ to +15̊ for the 27 cases in group A, with a median absolute deviation of 8̊±6̊. That in the 28 cases after the introduction of the new guide system (group B) ranged from -5̊ to +6̊, with a median absolute deviation of 0.5̊±3̊ (P<0.001). The total numbers of attempts to place lag screws and mean operation time decreased significantly after introduction of the new guide system (P<0.001). CONCLUSIONS With this new guide system, we are able to insert lag screws successfully in the optimal position even in most unstable fractures. The present study indicated that this new guide system and nail facilitate accurate placement of lag screws in the appropriate position with the minimum number of attempts.

Proximal femoral nail shows better concordance of gait analysis between operated and uninjured limbs compared to hemiarthroplasty in intertrochanteric femoral fractures

PURPOSE The purpose of this study was to compare the results of pedobarographic gait analysis between the patients treated by proximal femoral nail or bipolar partial hemiarthroplasty due to intertrochanteric fractures. METHODS Thirty-seven patients with a minimum 1-year follow-up who had been operated for intertrochanteric fractures were evaluated clinically, radiologically and with pedobarographic gait analysis. Proximal femoral nail had been performed to 21 patients (group A), whilst 16 patients had been operated by partial bipolar hemiarthroplasty (group B). Pedobarographic analysis was performed by measuring plantar pressure, force and contact area values in both static and dynamic manner. Pedobarographic results of operated limb were compared among groups. Same datas also were compared between operated and uninjured limbs in each group to determine any asymmetry on weight-bearing. RESULTS Average follow-up period in group A and group B was 36 (12-56) and 30 (12-48) months, respectively. There were no statistically significant differences among groups in terms of age, gender, body mass index, type and side of fracture, follow-up period, leg length discrepancy and postoperative hip scores. When the pedobarographic results of operated limb were compared, group B showed much more plantar force and pressure values than group A, on both static and dynamic evaluations. If the evaluation was taken into consideration to comparison of pedobarographic results between operated and uninjured limbs in each group, we found asymmetry in static load bearing, caused by higher load on uninjured limb in both groups. However, there was no statistically significant asymmetry between operated and uninjured limbs in respect to dynamic pedobarographic parameters for patients in group A. On the contrary, operated limbs in group B exposed much more plantar force and pressure values than uninjured limbs, which indicated asymmetric weight-bearing on dynamic evaluation. CONCLUSIONS Assessment of pedobarographic parameters can be another way of measuring the results of treatment in intertrochanteric fractures. Uninjured limbs of patients expose much more loading than operated limbs in postoperative static evaluation for both treatment options. However in dynamic evaluation, there is a better concordance of gait analysis between both limbs in patients operated by proximal femoral nail.

Sciatica due to Schwannoma at the Sciatic Notch

Schwannomas are rarely seen on the sciatic nerve and can cause sciatica. In this case report we aimed to present an unusual location of schwannoma along sciatic nerve that causes sciatica. A 60-years-old-man was admitted to us with complaints of pain on his thigh and paresthesia on his foot. Radiography of the patient revealed a solitary lesion on the sciatic nerve. The lesion was excised and the symptoms resolved after surgery.

A case of intramuscular myxoma presenting as a swollen shoulder: a case report

IntroductionIntramuscular myxoma is a rare benign mesenchymal tumor. Myxomas most commonly occur in the heart. They may occur less frequently in aponeurotic tissues, bone, genitourinary tract, subcutaneous tissue and skin.Case presentationThe case described here is a 44-year-old Turkish woman who presented with the complaint of a swelling in her right shoulder. A preoperative magnetic resonance imaging revealed a lobular contoured mass lesion in her deltoid muscle. The mass was marginally excised and pathology revealed intramuscular myxoma.ConclusionIntramuscular myxoma of the deltoid muscle is a very rare benign tumor. In the differential diagnosis, reactive lesions, myxoid nodular fasciitis and low -grade myxoid sarcomas should be kept in mind, upon which the treatment should be planned.

Irreducible Fifth Metatarsophalangeal Joint after Car Crush Injury

Metatarsophalangeal joint dislocations are uncommon injuries. Herein, an irreducible dislocation of fifth metatarsophalangeal joint with fractures on the second, third, and fourth metatarsal head was reported. Joint reduction could not be achieved which necessitated open reduction. Six months after surgery the patient was walking and doing his daily activities without any complaints. He had returned to his pretrauma functional level.

Effects of Local Application of Nano-silver on Osteomyelitis and Soft Tissue Infections: An Experimental Study in Rats

Purpose: Bone and soft tissue infections are among the least desired complications after orthopaedic surgery. This study analysed the in vivo effects of the local application of nano-silver particles (AgNPs) [1nm = 1 billionth of a meter] in soft tissue infections. Materials-Method: An experimental osteomyelitis model was formed by inoculating both tibias of 24 rats with methicillin-resistant Staphylococcus aureus. The rats were followed without treatment for 21 days. Blood samples and tibial x-rays at day 21 confirmed the development of infection. Then, the rats were divided randomly into two groups. One group (12 rats) underwent surgical debridement and received 21 days of teicoplanin therapy. The second group had the same treatment, with the addition of local nano-silver. All of the rats were sacrificed at day 42. Blood and wound swab samples were taken and the culture results were analysed. Results: No differences were observed between the groups in healing values at pathological examination, or in changes in the number of colonies at days 21 and 42. No differences in white blood cell count (WBC) were observed between the groups before and after the treatment. Conclusion: Although in vitro studies suggest the effectiveness of AgNPs on pathogens, we found that the application of nano-silver did not make any difference when used in addition to the classical osteomyelitis treatment with antibiotics and local surgical debridement. We believe that additional in vivo studies using repeated nano-silver application could be beneficial.

Occupational injury study in jockeys in Turkey: Relationship between experience, type of injury and localization

Equestrian sports are known as potentially dangerous sports that are vulnerable to damage to the spine and extremities. The aim of this study is to characterize the type and localization of injuries and evaluate their relationship with occupational experience. In-between 2015-2017, records of orthopedic injuries during horse riding in jockeys were retrospectively evaluated. Patients were divided into 2 subgroups according to their professional experience. Winners up to 100 races were classified as amateur (apranti jockey), more than 100 race winners were classified as experienced (jockey). Localizations of injury types were divided into bones and soft tissue, and their relationship between age and experience were statistically evaluated. Eighty-five patients were included in this study. The mean age was 24.6 (17-32). Thirty-nine patients were classified as amateur and 46 patients were classified as experienced. Thirtytwo of 85 patients were treated conservatively. Of the eighty-five patients, 53 were treated with surgical methods. There is no statistically significant difference between experience, type and localization of injuries (p>0.05). The results of this study makes us think that horse sports are open to serious injuries that require surgical treatment and always requires high levels of attention independent from experience.

An Unusual Orthopaedic Disease: Sarcoidosis—A Case Report

Sarcoidosis is an idiopathic, noncaseating granulomatous disorder with wide systemic involvement. It is encountered widely around the world and it affects both sexes, all the races in all age groups. Lungs, eyes, and skin are the organs most commonly affected. Constitutional features such as weight loss, fatigue, and myalgia are the most common symptoms. Bone involvement, which is very rare, was reported as present in 3 to 13% of effected cases, and it is most commonly seen in hands and feet, compared with long bone involvement, which is extremely rare. We hereby present a case with a diagnosis of sarcoidosis and multiple bone involvement emphasizing the importance of differential diagnosis.

Unexpected Injury During Jumping Exercise Isolated Subtalar Dislocation in A National Athlete

Objectives: The purpose of this case presentation is to report the results of physical therapy and conservative treatment of a rare clinical entity, isolated subtalar dislocation that occurred during triple jumping during which maximum compression forces act on the foot. Methods: A 20 years old national triple jumping athlete fell during daily sports exercises which consist of jumping to the medial and lateral side trying to catch a sports ball bouncing from the wall while his right foot was inverted and in plantar flexion. The patient was admitted to our emergency service. The physical examination revealed that the hindfoot was displaced medially. The neurological examination was intact and there was no sign of dermal injury. After the radiological examination the diagnosis was isolated subtalar dislocation. The dislocation was reduced with longitudinal traction with the knee was in flexion. The MR imaging did not reveal any chondral damage. The choice of treatment was conservative. After 4 days as the edema subsided, a short leg cast was applied for four weeks. Then, the cast was removed and active range of motion exercises were initiated. The first 25 days consisted of exercises with rubber band, bottle rolling under the foot. The second phase included walking in the pool and the patient was asked to start weight bearing partially. The patient went on with proprioception and strengthening exercises. Later, kinesiologic taping was also added to the therapy. He changed his jumping foot and started his routine training program with the team after 170 days. He participated in his first official competition 16 months after the injury. At the 28. month, he broke the national record in the National Interuniversities Athletics Games. 2 months later, he got the third place in the World Athletics Championship. Results: The follow up period was 4 years. AOFAS score was 76 at second month and 83 at the fourth. At the first and at the fourth year, AOFAS score was 100. No dermal lesions or joint stiffness or signs of arthritis was observed. Avascular necrosis of talus or complex regional pain syndrome was not encountered. Conclusion: Early return to sports activities is of tantamount importance as early reduction. Reduction can be carried out in an open or closed manner. For prevention of joint stiffness, immobilization period has to be short and active ROM exercises has to be initiated with partial weight bearing as soon as the joint stability and strength is adequate.
