A new measurement method in Graf technique: prediction of future acetabular development is possible in physiologically immature hips.

BACKGROUND: Universal ultrasound screening has led to overtreatment and higher follow-up rates than are found with clinical examination alone because of high incidence of physiologically immature hips (type IIa) in the first weeks of life. The ability to predict future acetabular development in physiologically immature hips (type IIa) would therefore help to reduce overtreatment and unnecessary follow-up. METHODS: We described the γ-angle to assess the femoral head coverage by the acetabular roof, which is measured between the baseline defined by Graf and the cartilaginous edge line connecting the inferior point of the iliac bone (lower limb) to the medial corner of the acetabular labrum. We retrospectively analyzed ultrasonographic findings of infants with developmental dysplasia of the hip diagnosed in our hospital and infants with normal hips screened in our hospital. Group 1 (35 hips) consists of type IIa hips at initial examination and went on to develop into dysplastic hips at follow-up. Group 2 (279 hips) consists of type IIa hips at initial examination and went on to develop into normal hips (type I) at follow-up. RESULTS: The γ-angles of type IIa hips that developed into type I hip at follow-up ranged between 77 and 82. The γ-angles of type IIa hips that developed into hip dysplasia ranged between 72 and 78. All type IIa hips that had γ-angles >78 degrees developed into normal hips. We also observed that all type IIa hips that had γ-angles <77 degrees developed into dysplasia. CONCLUSIONS: The amount of cartilage mass covering the femoral head, which is a part of the acetabular roof, can therefore provide information about future acetabular development. This paper describes a new method of measurement (the γ-angle) that assesses the extent of the cartilage coverage of the femoral head, which can predict acetabular development. Its use would decrease the rates of unnecessary follow-up and treatment. LEVEL OF EVIDENCE: Level II (development of diagnostic criteria on the basis of consecutive patients).

Results of Tönnis-type acetabuloplasty in patients with developmental hip dysplasia.

AIM: The aim of this prospective study was to evaluate the outcome of open reduction and Tönnis acetabuloplasty as the first method of treating developmental dysplasia of the hip (DDH) in children in early childhood at walking age. MATERIALS AND METHODS: Between 2005 and 2009, 34 hips of 34 children were operated on with the aforementioned method. Mean age was 25.6 (range 12-44) months, and mean follow-up was 3.6 years. During the follow-up period ,the hips were evaluated using the acetabular index and for development of avascular necrosis and redislocation. Functional evaluation was also conducted. RESULTS: Clinically, 97.3 % of patients had excellent and good results. The acetabular angle decreased from 45° preoperatively to 21° early postoperatively and at the last follow-up had improved to 18°. In two hips, type 2 avascular necrosis developed. Hip instability was not observed, and no additional surgery was performed. CONCLUSION: Tönnis acetabuloplasty is a powerful tool to increase primary stability of the hip when acetabular coverage is inadequate in DDH. Besides its acute correction ability, when performed properly, it has no unwanted effects on acetabular growth. As an isolated procedure or as a part of combined open reduction and/or femoral osteotomy, Tönnis type acetabuloplasty is a safe and effective method.

[Real angulation degree in fifth metacarpal neck fracture]. / Besinci metakarp boyun kiriginda gerçek açilanma degeri.

OBJECTIVES: This study investigated whether the confusion about the acceptable angulation value in fifth metacarpal neck fractures results from the hand radiographs taken at non-standard oblique position. MATERIALS AND METHODS: In this experimental study two Kirshner wires representing the intramedullary axis of the two fracture fragments were placed on a platform prearranged with an angle of 50 degrees between them. The radiographs of the wires were taken on the platform (horizontal) at angles of 0, 30, 45 and 60 degrees. The radiographs were taken without changing the cassette location and the position of the radiography device. RESULTS: The known volar angulation (50 degrees) was measured on the radiographs as 50, 36, 30 and 23 degrees, respectively. CONCLUSION: The main debate about the fifth metacarpal neck fracture is over the acceptable distal fragment volar angulation degree. This degree of angulation is between 30 and 70 degrees in the studies. The presence of such different and inaccurate results in the literature results from the use of non-standard oblique hand radiographs. Standardized radiographs are required in fifth metacarpal neck fractures.

[An alternative fixation method for the treatment of unstable distal clavicle fractures: locked distal radius plate]. / Distal klavikula ayrismali kiriklari için yeni bir tespit yöntemi: Kilitli distal radius uç plagi.

OBJECTIVES: Optimal surgical fixation method for displaced distal clavicle fractures should not impose limitations on neighboring joint movements. We evaluated the results of surgical treatment of displaced distal clavicle fractures using locked distal radius plates. METHODS: Displaced distal clavicle fractures of 14 consecutive patients (11 men, 3 women; mean age 30 + or - 9 years; range 19 to 51 years) were treated using open reduction and locked distal radius plates. Before final fixation, one patient underwent K-wire fixation with tension band at another center, resulting in nonunion. Except for two cases with late presentation, the mean time to surgery was 5.3 days (range 1 to 17 days). According to the Neer classification, fresh fractures were type II in 10 patients and type III in three patients. Shoulder examinations and functional evaluations were made at 3, 6, and 12 months postoperatively. Functional assessment included the Modified Shoulder Rating Scale and Constant score. RESULTS: All patients achieved full range of motion of the shoulder at six weeks postoperatively. The mean modified shoulder score was 18.7 + or - 1.5 and the mean Constant score was 95.4 + or - 3.0 at 12 months. None of the patients developed implant failure, loss of reduction, skin breakdown, or infection. CONCLUSION: In selected acute fractures and nonunions of the distal clavicle, excellent clinical results are easily achievable with locked distal radius plate fixation because it allows early shoulder movements without necessitating implant removal.

Results of triple arthrodesis: effect of primary etiology.

BACKGROUND: Severe disability originating from feet generally requires surgery. In addition to a number of other techniques, triple arthrodesis is still used to treat deformity and instability unresponsive to conservative measures. The aim of this study was to evaluate the results of the triple arthrodesis operation in two groups of patients with different primary etiologies and to identify the possible factors affecting the results. METHODS: During a 4-year period, triple arthrodesis was performed on 25 feet in 20 patients (average age 24.9 years). These patients were divided into two groups according to the primary etiology of the disability: neurogenic and nonneurogenic. Patients were evaluated with pre-and postoperative clinical examinations, American Orthopedic Foot and Ankle Society (AOFAS) Hindfoot and Ankle Scale, radiography, pedobarography, and a general health questionnaire (Short Form 36, SF-36). The need for orthotics and the effect of previous treatments on the end results were also evaluated. RESULTS: The preoperative average AOFAS score improved from 24 to 71 postoperatively. Preoperative AOFAS values of neurogenic cases were significantly lower than those of nonneurogenic cases. Postoperative AOFAS values were found to be lower in neurogenic cases (64.0 vs. 77.6). Marked improvement was observed for all angular measurements. No relation was found between the AOFAS, changes in angular measurements, and pre-and postoperative plantar pressure analysis results. SF-36 results improved postoperatively in both groups. Triple arthrodesis decreased the use of orthotics postoperatively in both groups. Previous treatments were not found to affect the end results in this series. CONCLUSIONS: Triple arthrodesis operation is a surgical option with limited alternatives in patients with disabilities originating from feet. Both neurogenic and nonneurogenic patient groups improved significantly, and we were unable to show any significant differences in the results of these two groups.

Alternative reliable techniques in femoral torsion measurement.

The clinical and conventional bi-planar determinations of femoral torsion were compared with the tomographic technique, the reliability of which was confirmed. Femoral torsions were measured with the trochanteric prominence angle test, the sinus-wave bi-planar conventional radiographic technique, the modified Hermann bi-planar conventional radiographic technique and the limited three-dimensional volumetric tomography technique in 34 femora of 17 patients. There was a strong correlation between the modified Hermann and the limited tomography techniques for 14 intact and 20 fractured femora. If limited three-dimensional volumetric tomography cannot be obtained, the modified Hermann bi-planar conventional radiographic technique must be used in patients who have scarring about the proximal femur and obesity. Otherwise use of the trochanteric prominence angle test is much more cost-effective and is as accurate as the limited three-dimensional volumetric tomography technique.

[The effect of long- or short-arm casting on the stability of reduction and bone mineral density in conservative treatment of Colles' fractures]. / Colles kiriklarinin konservatif tedavisinde kisa veya uzun kol alçilamanin kemik mineral yogunlugu ve redüksiyon üzerine etkisi.

OBJECTIVES: We evaluated the effect of long- or short-arm casting on the stability of reduction and bone mineral density (BMD) in the forearm in patients treated conservatively for Colles' fractures (CF). METHODS: Eighty-three patients (48 females, 35 males; mean age 53 years; range 30 to 76 years) with an isolated unilateral CF underwent closed reduction followed by a randomly assigned long-arm (n=44) or short-arm (n=39) casting. Fractures were classified according to the Frykman's system. After reduction, radiographs of both forearms were taken, on which radial height and inclination, and volar tilt were measured and assessed according to the criteria by Sarmiento et al. In the first week, BMD measurements were made on the unaffected side to obtain reference values from four sites of the forearm, namely ultradistal, 1/3 proximal, middle diaphysis, and total. Following removal of the casts (mean 45.3 days; range 40 to 55 days), radiographic and BMD assessments were repeated. Osteoporosis was defined according to the criteria of the World Health Organization. RESULTS: The two casting groups were similar with respect to age, sex, Frykman's classification, involved side, and the dominant extremity. Osteoporosis was detected in 20% according to the T scores. All the sites in the fractured forearm showed density losses, but the difference was significant only in the middle diaphysis (p<0.05). No significant relationship was found between BMD losses and the cast type. Angular measurements showed significant deterioration after union; however, none was found to be related to the cast type (p>0.05). CONCLUSION: Our results show that BMD losses and deterioration in reduction following treatment of CF occur irrespective of which type of casting is used.

[Importance of lumbar vertebra transverse process fractures in multitrauma patients who had undergone emergent laparotomy]. / Acil laparotomi yapilan multitravmali hastalarda lomber vertebra transvers çikinti kiriklarinin önemi.

BACKGROUND: To evaluate the incidence and importance of lumbar vertebra transverse process fractures in polytraumatized patients who had undergone emergent laparatomy, and to find out the relevant risk factors. METHODS: The medical records of 312 laparotomized trauma patients who referred to our emergency department between January 2001 and January 2002 were retrospectively assessed. Hundred and six cases who met inclusion criteria were investigated. Data relevant to the trauma, demographics, hemoglobine levels, additional system traumas, complications were recorded. Correlations between collected data and the fractures were investigated. Results were evaluated statistically using SPSS 11,0 software package program. RESULTS: Lumbar vertebra transverse process fractures were detected in 58,5 % of the cases. They were more frequently encountered in women, elderly and after falls or traffic accidents.. Abdominal organ injuries were more common in these cases. These fractures are associated with hepatic and splenic injuries. Their presence also increases the risk of vertebra corpus fractures seven fold. CONCLUSIONS: Lumbar vertebra transverse process fractures usually occur after higher energy traumas They must be evaluated as serious findings which might lead to potential organ injuries. Once these fractures were detected in trauma patients, every attempt should be made to exclude probably fatal and more serious additional organ injuries.

Which one is at risk in intraoperative fluoroscopy? Assistant surgeon or orthopaedic surgeon?

BACKGROUND: Orthopaedic surgeons use intraoperative portable fluoroscopy and roentgenography. The present study was an attempt to find out if there is a difference between the occupational radiation exposure to the orthopaedic surgeon and assistant surgeon in the operating room while using intraoperative fluoroscopy or radiographic control and to measure it. METHODS: During a 3-month period, 107 consecutive operations were monitored for radiation exposure. At monthly intervals, the radiation doses were measured in millirem and recorded. The distance of the orthopaedic surgeon and the assistant surgeon from the X-ray source were noted in every fluoroscopic check. The orthopaedic surgeon was always at a safe distance (more than 90 cm), but the assistant surgeon always stood nearby (10 cm) the X-ray source for positioning of the patient. RESULTS: The radiation exposure according to the badge on the shoulder was consecutively 3, 4, 3 mrem for the orthopaedic surgeon and 20, 19, 22 mrem for the assistant surgeon. The radiation exposure according to the badges on the anaesthetic machine, in the room and under the apron of the orthopaedic surgeon were all zero, whereas the readings of the badge under the apron of the assistant surgeon were 7, 6, 5 mrem consecutively. CONCLUSION: Our findings show that although the radiation exposure during orthopaedic operations is below the recommendations of the European Committee on Radiation Protection, there is a higher risk of exposure for the assistant surgeon. It has to be kept in mind that there could be morphological and functional damage in cells exposed to radiation. Therefore, we should continue to use appropriate shielding precautions in view of the unknown long-term risks.
