Rare injury of the foot: Os trigonum fracture: A case report.

Os trigonum fractures are seen rarely. Our patient was a 16-year-old male patient who applied to our emergency service with right ankle pain due to acute hyperplantar flexion while playing football. There was a swelling on the right ankle and he had difficulty in walking. Os trigonum fracture was detected at lateral X-ray of the right ankle. No additional injury was detected with computed tomography and magnetic resonance imaging (MRI). Patient was treated conservatively. A short leg cast was applied. Cast was removed after six weeks and range of motion exercises were started. Union of fracture was seen on X-ray at six weeks from injury. Conservative treatment is thought to be a good option in these fractures. Computed tomography and MRI are important in the differential diagnosis and evaluation of additional injuries in this type of fracture.

Mid-Term Results of Two Different Fixation Methods for Chevron Osteotomy for Correction of Hallux Valgus.

We compared 2 different fixation methods (bioabsorbable pins and cannulated screws) after chevron osteotomy for the treatment of hallux valgus. We reviewed consecutive proximal chevron osteotomies in 80 patients (100 feet) performed by 2 surgeons. Of the 100 feet (80 patients), 48 feet (40 patients) were stabilized with bioabsorbable pins, and 52 feet (40 patients) were stabilized with cannulated screws. In the pin group, 8 patients were male (20%) and 32 were female (80%). In the screw group, 10 patients were male (25%) and 30 were female (75%). The mean patient age was 43.1 (range 24 to 60) years in the pin group and 43.5 (range 20 to 60) years in the cannulated screw group. The visual analog scale, intermetatarsal angle, and hallux valgus angle decreased significantly and the American Orthopaedic Foot and Ankle Society scores increased significantly in all patients in both groups after surgery (p < .05). No statistically significant differences were found between the 2 groups (p > .05). Both fixation methods were found to be safe and reliable under the appropriate conditions and when performed by an experienced surgeon.

Comparison of Anteromedial and Transtibial ACL Reconstruction Using Expandable Fixation.

The influence of anatomical or nonanatomical femoral tunnel position on tunnel widening and clinical outcomes in patients undergoing anterior cruciate ligament (ACL) reconstruction is not fully understood. This retrospective study examined the influence of tunnel width and placement on anterior knee stability and clinical outcomes after ACL reconstruction using the AperFix System (Cayenne Medical Inc, Scottsdale, Arizona), a direct expandable fixation technique with autologous hamstring grafts. The records of 80 patients (79 men and 1 woman) who underwent ACL reconstruction were evaluated. In 38 patients, anatomical femoral tunnel placement was performed via an accessory medial portal (anteromedial group); in the remaining 42 patients, the femoral tunnel was positioned nonanatomically using a transtibial technique (transtibial group). Mean follow-up was 40.7 months (range, 27-60 months). Postoperative knee kinetics were measured, and clinical outcomes were assessed using International Knee Documentation Committee, Lysholm, and Tegner scores. Femoral tunnel widening was measured by comparing postoperative radiographs with final follow-up radiographs. Femoral tunnel width was significantly greater (P<.001) and anterior knee translation was significantly higher (P=.01) in the transtibial group. Lysholm and Tegner scores were not significantly different (P>.05) between the 2 groups. These findings suggest that femoral tunnel widening is associated with increased anterior joint laxity when a direct fixation technique is used for ACL reconstruction, particularly in nonanatomically positioned femoral tunnels. Anatomical femoral tunnel placement provides better anterior stability and less tunnel widening than transtibial tunnel placement; however, these benefits did not produce a detectable advantage in clinical outcomes measures.

Changes in posterior tibial slope angle in patients undergoing open-wedge high tibial osteotomy for varus gonarthrosis.

PURPOSE: In this study, postoperative changes in the posterior tibial slope angle and clinical outcomes following open-wedge high tibial osteotomy were evaluated. METHODS: This study included 39 knees (18 left, 21 right) of 35 patients (three male, 32 female; median age, 53 years; age range 37-64 years) with symptomatic isolated medial joint osteoarthritis who underwent open-wedge high tibial osteotomy and fixation with a Puddu plate. The patients were clinically assessed according to the Lysholm knee score, a visual analogue pain scale, and a patient satisfaction questionnaire. Radiological assessment was made according to the changes in the posterior tibial slope angle and the correlation between these changes and clinical signs. The median follow-up period was 11 years (range 7-14 years). RESULTS: Significant improvements were observed in the preoperative and postoperative clinical scores of the Lysholm knee scale, visual analogue pain scale, and patient satisfaction questionnaire (p < 0.05). Radiological assessment showed that the posterior tibial slope angle was significantly higher during the postoperative and follow-up periods (p  0.05). There was no correlation between the postoperative Lysholm scores and the increase in the posterior tibial slope angle (p = n.s.). CONCLUSIONS: We conclude that both the conventional Puddu plate design and its anteromedial plate placement are what increase the tibial slope after an opening-wedge proximal tibial osteotomy. Therefore, current new plate design may help preserve the posterior tibial slope angle. LEVEL OF EVIDENCE: IV.

A new method of calculating the rotation angle in pediatric forearm fractures using direct radiographs.

BACKGROUND: The aim of this study was to measure the rotational angle defect between fracture ends in paediatric forearm diaphyseal fractures on radiographs. METHODS: Evaluations were performed on 78 paediatric patients who presented at the emergency department with a diaphyseal forearm fracture during 2013-2014. Thirty-two patients who underwent conservative treatment and had < 10° of angulation and translation of not more than half the bone diameter after application of a plaster cast were included in the study. A rotational formula was used with diameter values to determine changes. The degree of rotation of both ends of the fracture line and the forearm rotational defect of the fracture line were calculated. FINDINGS: Fractures included an isolated radius in 16 cases, an isolated ulna in four cases, and both bones in 12 cases. The mean lateral angular (LAT-θ) value was 26.13 ± 5.93° on the proximal fracture end, and the distal mean LAT-θ was 30.29 ± 6.24° (p = 0.037).The mean proximal anteroposterior angular (AP-θ) value was 26.83 ± 5.75°, and the distal mean AP-θ was 30.58 ± 7.27° (p = 0.008). A significant correlation was detected between the AP-Δ and LAT-Δ measurements (p = 0.883). INTERPRETATION: The rotational defect was mathematically calculated directly from radiographs using a rotational measurement formula.

Concomitantly intra-articular fracture of proximal condylar second and third proximal phalanges: A rare case report.

INTRODUCTION: A rare case of proximal phalange fractures has been presented in this study. PRESENTATION OF CASE: A 29-year-old male patient from Turkey was admitted to the orthopedics and traumatology clinic with a complaint of left hand pain, which had persisted for 10days. He described a rotational trauma that had occurred right after hitting his hand on the wheel of a car as a result of an in-car traffic accident 10days ago. Radiological work-ups were requested. In the anteroposterior (AP) graph of the case in which the fracture line could not be observed in the oblique graph, unicondylar fractures in the proximal section of the second and third proximal phalanges have been observed. Surgical treatment was not planned because 10days had passed since the trauma. In the control graphs taken after 3 weeks, healing at the fracture site was observed, and he was referred to physiotherapy after the removal of the splint. A good result was observed after physiotherapy. DISCUSSION: Because of the extension of tendons is important over the bone, the goal of the treatment is not only to heal the fracture, but also to preserve the sliding mechanism of these tendons. Regarding to lack of soft tissue trauma, favored joint movements after the healing of the fracture can be achieved more easily with conservative treatment; however, the fracture must be closely followed up. CONCLUSION: Condylar fractures of proximal phalanges those nondisplaced can be conservatively treated with closed methods.

Measurement of Malrotation on Direct Radiography in Pediatric Distal Radius Fractures: Prospective Observational Study.

UNLABELLED: The aim of this prospective study was to test a mathematical method of measuring the malrotation of pediatric distal radius fractures (PDRFs) from direct radiographs. A total of 70 pediatric patients who presented at the Emergency Department with a distal radius fracture were evaluated. For 38 selected patients conservative treatment for PDRF was planned. Anteroposterior and lateral radiographs were taken of all of the patients for comparison before and after reduction. Radius bone diameters were measured in the coronal and sagittal planes on the healthy and fractured sides. Using the diameter values on the healthy side and the new diameter values on the fractured side in the rotation formula, the degree of malrotation between the fracture ends was calculated. The mean follow-up period was 13.5 months. Patients' mean age was 10.00 ±â€Š3.19 years (range, 4-12 years). The rotation degree in the sagittal plane significantly differed between the proximal (26.52°±2.84°) and distal fracture ends (20.96°±2.73°) (P = 0.001). The rotation degree in the coronal plane significantly differed between the proximal (26.70°±2.38°) and distal fracture ends (20.26°±2.86°) (P = 0.001). The net rotation deformity of the fracture line was determined to be 5.55°± 3.54° on lateral radiographs and 5.44°± 3.35° on anteroposterior radiographs, no significant difference was observed between measurements (P >0.05). The malrotation deformity in PDRF occurs with greater rotation in the proximal fragment than in the distal fragment. The net rotation deformity created between the fracture ends can be calculated on direct radiographs. LEVEL OF EVIDENCE: Diagnostic, Level II.

Arthroscopic treatment of synovial chondromatosis of the shoulder: A case report.

INTRODUCTION: Synovial chondromatosis is a mono-articular arthropathy rarely seen in diarthrodial joints. The classic treatment for synovial chondromatosis is open arthrotomy, synovectomy and complete removal of the free fragments. With recent advances in arthroscopic techniques and methods, the indications for arthroscopic treatment have been extended. PRESENTATION OF CASE: A 33-year old female presented with complaints of pain in the right shoulder. On the radiological examination, there were seen to be multiple calcified radio-opaque lesions filling all area of the glenohumeral joint. On computed tomography (CT) examination, again multiple radio-opaque free fragments were determined. Arthroscopy was applied to the right shoulder. The free fragments were completely removed. Approximately 33 free fragments, ranging in size from 0.5 to 1.3 cm, were removed. DISCUSSION: Cases of synovial chondromatosis in the shoulder have been rarely reported in literature. Generally the disease is self-limiting. Clinically, symptoms are generally not specific. Restrictions in the joint range of movement occur associated with the mechanical effect of the free fragments and in periods of active use, local pain and swelling may be seen in the shoulder. Simple removal of the free fragments, others have stated that removal with synovectomy is necessary to prevent recurrence of the cartilaginous metaplastic focus. Recurrence rates vary from 0 to 31%. CONCLUSION: Arthroscopic surgery can be successfully applied in the treatment of synovial chondromatosis. The advantages of the method include good visualisation during surgery, low morbidity and early healing.

Magnetic resonance imaging-based diagnosis of occult osseous injuries in traumatic knees.

BACKGROUND: Occult osseous knee injuries, such as bone bruises, can produce persistent pain and functional loss. Although bone bruises cannot be identified through direct examination or traditional radiographs, magnetic resonance imaging (MRI) has emerged as an effective diagnostic method. Nevertheless, the natural history of these injuries remains to be fully defined. Therefore, we used MRI to detect and follow bone bruise injuries secondary to knee trauma. METHODS: We retrospectively reviewed knee MRIs from patients with bone bruising caused by trauma. Occult injuries were initially identified by MRI and subsequently rescanned for follow-up at 3 and 9 months. All patients underwent physical examinations, direct radiological imaging, and MRI. RESULTS: Although direct radiographs showed no abnormalities, we used MRI to identify a total of 22 patients (age range: 19-42 years; mean: 28 years) with bone bruising. After 3 months, injuries remained detectable in 68.2% of the subjects, whereas 18.2% displayed bone bruising after 9 months. The majority of Type I lesions resolved spontaneously, whereas 80% of Type II injuries remained following 3 months, and 30% persisted at 9 months. Ligament and meniscal lesions were observed in 63.6% of patients with bone bruising and appeared to hinder recovery. CONCLUSION: Bone bruises generally resolved within 3 to 9 months in subjects with no soft tissue lesions and minor trauma. However, ligament and meniscal lesions were observed in the majority of patients, and these individuals required longer treatment and recuperation. Overall, these findings can contribute to improving the management of occult osseous knee injuries.

Arthroscopic removal of giant loose bodies in the glenohumeral joint.

INTRODUCTION: Loose bodies within the joint because of any cause have the potential for continued growth. PRESENTATION OF CASE: A 41-year-old man had suffered multiple recurrent dislocations of his left shoulder, accompanied with pain. His anterior apprehension and relocation tests were positive, but no other sign was noted on physical examination. On magnetic resonance imaging and at arthroscopy, two giant loose bodies were seen. They were in the axillary recess and were removed arthroscopically. DISCUSSION: Most authors recommend surgical removal of the cartilaginous loose bodies to ameliorate the symptoms. Furthermore, the majority of authors recommend a synovectomy to decrease the risk of recurrence. Depending on the size of the chondral loose bodies, removal can be performed via an arthrotomy, arthroscopy with mini-open arthrotomy, or arthroscopy. CONCLUSION: The source of the loose body should be determined carefully. Other lesions may be associated with the loose body. Arthroscopic treatment is a good option for removing the loose body.
