Management of AO type 12C humerus proximal metadiaphyseal fractures with minimally invasive plate osteosynthesis in geriatric patients.

BACKGROUND: To evaluate the treatment efficacy and complications of the lateral minimally invasive plate osteosynthesis (MIPO) method in geriatric patients with a humerus diaphyseal fracture with proximal extension. PATIENTS AND METHODS: The study included a total of 21 patients (18 females, 3 males; mean age 74±6.3 years, range 65-89 years) who underwent surgery with the lateral MIPO technique for a humerus diaphyseal fracture with proximal extension during the period January 2011 to December 2016. None of the patients had additional injuries and all completed regular follow-up. According to the Arbeitsgemeinschaft für Osteosynthesefragen/Association for the Study of Internal Fixation classification system, the fractures were evaluated as 12C1 in 17 cases and 12C3 in 4 cases. All patients were evaluated radiologically and functionally at 6 months and 1 year. In the follow-up evaluations, the Constant-Murley score and the Quick Disabilities of the Arm, Shoulder, and Hand (Q-DASH) score were used. RESULTS: No non-union, avascular necrosis or infection was seen in any patient. The mean time to union was 15.7 weeks. Impingement syndrome was seen in 2 patients and radial nerve palsy in 2 patients. The mean Constant-Murley score was 70.6±10.2 at 6 months and 84±7.6 at the end of 1 year. The mean Q-DASH score was 38.6±15.1 at 6 months and 21.9±13.1 at the end of 1 year. The increase in the Constant-Murley scores from 6 months to 1 year was statistically significant (p<0.0001). The decrease in the Q-DASH scores between 6 months and 1 year was determined to be statistically significant. In the 2 patients with radial nerve palsy, the functions were seen to completely recover during follow-up. No axillary nerve palsy was seen in any patient. CONCLUSION: Metadiaphyseal humerus fractures with proximal extension in the elderly can be successfully treated with the lateral MIPO technique. When applied correctly, it is a method with high rates of union and low rates of complications.

Percutaneous achillotomy in the treatment of congenital clubfoot: should it be performed in the operating theater or the polyclinic?

BACKGROUND: The aim of this study was to compare the efficacy, advantages, and complications of percutaneous achillotomy in the treatment of clubfoot with the Ponseti method when performed to two different groups under general anesthesia or polyclinic conditions with local anesthesia. METHODS: A retrospective evaluation was made of 96 patients treated for clubfoot in our clinic between January 2013 and June 2016. Fifty-seven patients were separated into two groups according to whether the achillotomy was performed in polyclinic conditions with local anesthesia or under general anesthesia following serial plaster casting with the Ponseti method. RESULTS: The characteristics of age distribution, mean week of tenotomy, side, and sex were similar in both groups. No statistically significant difference was determined between the two groups in respect to complication and recurrence. The durations of hospitalization-observation, separation from the mother, and fasting were found to be statistically significantly shorter in local anesthesia group. CONCLUSION: Although the performance of percutaneous achillotomy with local or general anesthesia has different advantages, it can be considered that especially in centers with high patient circulation, achillotomy with local anesthesia can be more preferable to general anesthesia because it is practical and quick, does not require a long period of fasting or hospitalization, and has a similar complication rate to general anesthesia procedures.

Evaluation of late redislocation in patients who underwent open reduction and pelvic osteotomy as treament for developmental dysplasia of the hip.

INTRODUCTION: The goal in the treatment of developmental dysplasia of the hip (DDH) is to achieve a stable and concentric reduction and to create a congruent relationship between the femoral head and the acetabulum. This study discusses the causes of loss of reduction in DDH patients who had a concentrically reduced hip at the time of removal of the hip spica cast and cessation of brace use and who later appeared with hip redislocation after mobilisation and ambulation. In addition, the possible interventions in such cases are also discussed. MATERIAL AND METHOD: A retrospective evaluation was made of 13 patients diagnosed with DDH who developed redislocation following primary surgery. 6 of them had undergone the 1st surgery in our department between 2008 and 2016 and 7 had udergone surgery in another centre. For comparison reasons a 2nd group was formed of 13 demographically and clinically matched patients who had no loss of reduction. The groups were compared in terms of acetabular index, pelvic length, pelvic width, abduction degree of plaster, ossifying nucleus diameter, acetabular depth, and acetabular volume parameters. RESULTS: The average age of the patients was 23 months at initial surgery and 29 months at the time of revision surgery. No significant difference was found between the groups in terms of acetabular inclination angle, ossifying nucleus diameter, pelvic size, pelvic width, centre edge angle, acetabular volume, and depth. Contracted inferomedial capsule was found in 1 patient who underwent revision surgery and intact transverse acetabular ligament was seen in 1 patient. The loss of reduction in the remaining 11 patients was associated with high total anteversion of the femoral head and acetabulum. CONCLUSIONS: Correction of increased combined anteversion by femoral osteotomy can create a safe zone in terms of redislocation and can significantly contribute to the stability provided by capsulorrhaphy and pelvic osteotomy.

A comparison of percutaneous trephine excision and open surgery in the treatment of osteoid osteoma.

PURPOSE: The aim of this study was to compare CT-assisted percutaneous excision, which is a closed, economic method and a more cosmetic approach, and open surgery in the treatment of osteoid osteoma. MATERIALS AND METHODS: Fifty-three patients (12 female and 41 male patients) who had percutaneous excision (n = 24) and open surgery (n = 29) were evaluated retrospectively. The mean age was 16.6 years and the mean duration of follow-up was 53.5 months. During percutaneous excision, a trephine was advanced through the labeling wire and the site, including the nidus, was excised en-bloc and the incision walls were curetted. During the open surgery, the localization of the nidus was marked using c-arm X-ray and the nidus was accessed by lifting the cortical bone, layer-by-layer, using burr. The nidus was excised and its cavity curetted. RESULTS: The result was successful in 22 and a failure in three patients who had closed excision. The result was successful in 20 and a failure in nine patients who had open surgery. The mean duration of operation was 44.37 minutes in the percutaneous excision group and 80.6 minutes in the open surgery group. There was no difference in the pre-operative VAS values between the two groups, whereas the post-operative VAS values were statistically significantly different. There was also a statistically significant difference in the duration of the operation and the length of the hospital stay between the groups. CONCLUSION: Percutaneous excision with trephine is a more successful, effective, minimally invasive, safe and a better cosmetic approach in the treatment of osteoid osteoma. This method is also a cheap method that does not require expensive equipment.

Management of infectious fractures with "Non-Contact Plate" (NCP) method.

The aim of this study was to evaluate the outcomes of internal fixation with Non-Contact Plating (NCP) after deep infection caused by previous surgeries of the tibia or femur fractures. The study included 15 patients (4 female and 11 male). The mean age patients was 36.6 years (range, 21-64 years). There were 6 femur and 9 tibia fractures. The mean follow-up period was 25.7 months (range, 15-45 months). The study comprised 11 open and 4 closed fractures. External fixator was used in 3, plate in 4, and intramedullary nail in 8 patients for index surgery. Deep infection was diagnosed via clinical findings, laboratory parameters, and microbiological evaulation. Deep infection was diagnosed within a mean period of 5.5 weeks (range, 2-10 weeks). The infecting organism was methicillin-resistant staphylococcus aureus (MRSA) in 5, methicillin-sensitive staphylococcus aureus (MSSA) in 6, pseudomonas auroginosa in 2, and enterobacteriacea in 2 patients. Union achieved in all patients. Mean time to union was 17 (range, 11-38) weeks. Delayed union was observed in 3 patients who required additional surgeries. Of these one patient developed osteomyelitis. The NCP is an effective alternative method in the treatment of deep infection encountered after internal or external fixation for the tibia, or femur fractures.

Open reduction and Kirschner wire fixation with triceps lengthening for neglected elbow dislocations.

PURPOSE. To evaluate outcome of open reduction and Kirschner wire fixation with triceps lengthening for neglected elbow dislocations. METHODS. Records of 6 women and 14 men aged 7 to 60 (mean, 20) years who underwent open reduction and Kirschner wire fixation with triceps lengthening for neglected elbow dislocations were reviewed. The dislocations were posterolateral (n=11), posterior (n=4), and posteromedial (n=5). No patient had a neurologic deficit. Elbow stiffness was the main indication for surgery. The duration of dislocation was 25 to 45 days in 11 patients and >45 days in 9; the mean was 47 days. The Mayo Elbow Performance Index (MEPI) was used to assess outcome at the final follow-up. The maximum score was 100. Scores of 90 to 100 were considered excellent, 75 to 89 good, 60 to 74 fair, and <60 poor. RESULTS. The mean follow-up period was 39.1 months. At the final follow-up, the mean MEPI score was 79.3; outcome was excellent in 6 patients, good in 8, fair in 4, and poor in 2. The mean MEPI was 86.4 and 70.6 for patients with ≤45 or less and >45 days of dislocation, respectively. The mean range of movement improved from 20 to 84.5 degrees (p<0.001). The 2 groups were significantly different in terms of MEPI (p=0.005) and range of movement (p=0.001). The MEPI correlated negatively with the duration of dislocation (r= -0.562, p=0.01). The range of movement correlated negatively with patient age (r= -0.649, p=0.002). CONCLUSION. Open reduction and Kirschner wire fixation with triceps lengthening, together with active postoperative elbow movements achieved favourable results for neglected elbow dislocations, especially in younger patients and those in whom the duration of dislocation was <45 days.

Primary xanthofibroma in the calcaneus: a case report.

Xanthoma or xanthofibroma is a lesion, characterized by foamy histiocytes (xanthoma cell) and is mostly seen in soft tissue. Xanthoma may also occur in in the skeletal system of patients with an abnormal lipid metabolism. We present a 22-year-old man with primary xanthofibroma in the calcaneus, who was treated by curettage and grafting of the lesion.

Outcome in unilateral or bilateral DDH treated with one-stage combined procedure.

UNLABELLED: The surgical treatment of patients with neglected developmental dysplasia of the hip (DDH) has been the subject of controversy. We asked if age affected outcome in patients with neglected DDH with unilateral or bilateral dislocation who underwent one-stage combined procedures. We retrospectively reviewed the results of 40 patients (51 hips) treated with a one-stage combined procedure consisting of open reduction, pelvic osteotomy, and femoral shortening. The average age at the time of surgery was 5.4 years for Group I (bilateral dislocation, 22 hips) and 6.7 years for Group II (unilateral dislocation, 29 hips). Mean followup was 5.4 years for Group I and 6.7 years for Group II. According to the modified score system of Trevor et al, 13 hips rated excellent, three were good, and six were fair in Group I; the ratings were 14, nine, and six hips respectively in Group II. Four patients had a limb-length discrepancy of approximately 1.5 cm in Group I. Twelve hips in Group I and 18 hips in Group II had osteonecrosis of varying severity. Our data suggest the outcomes of the children who were 5.5 years or younger in Group I and 8 years or younger in Group II were better. LEVEL OF EVIDENCE: Level IV, case series. See the Guidelines for Authors for a complete description of levels of evidence.

Effect of lymphedema on the recovery of fractures.

BACKGROUND: Lymphedema delays the healing of any wound by negatively affecting its inflammatory period. Whether it affects bone healing in a similar negative manner is unknown. Therefore, we experimentally investigated the effect of lymphedema on fracture recovery. METHODS: We used thirty 200- to 250-g Sprague-Dawley rats for the experiment. The rats were randomly divided into two groups of 15 rats each for the experimental lymphedema and control groups. Lymphedema development was confirmed by measuring the circumference and diameter of the extremities together with lymphoscintigraphy. Twenty days after the development of lymphedema, a fracture model was created in both groups in the right tibia with mid-diaphyseal osteotomy and fixing with an intramedullary Kirschner wire. After 6 weeks, all rats were sacrificed and the callus tissue that formed along the osteotomy was compared between groups with respect to radiographic, histological, and biomechanical characteristics. RESULTS: The three-point bending test yielded an average stiffness value of 1227 N/mm (n = 6) in the control group and 284 N/mm (n = 7) in the experimental lymphedema group (P < 0.05). At the end of week 6, radiographic evaluation showed that solid knitting was obtained in the control group, whereas in the lymphedema group delayed or no knitting was observed. In the control group, histological investigation revealed normal callus morphology. Trabecular bone was normal and osteoblast and osteoclast activity was clearly evident. The bone was stained homogeneously with hematoxylin and eosin, and ossification was within normal limits. In the lymphedema group, however, the histological appearance was mostly that of scar tissue. In addition, osteoblast and osteoclast activity was much less visible or absent. CONCLUSIONS: Lymphedema negatively affected bone healing in rats. However, the mechanism of this negative effect and its occurrence in humans are still unknown. Further experimental and clinical studies are needed to support and extend our findings.

Successful treatment of hemophilic hand pseudotumors by only radiotherapy.

Hemophilic pseudotumor is a rare complication of hemophilia. We describe a 14-year-old young male with hemophilic pseudotumor in the second and fifth fingers of the left hand. We treated him only with radiotherapy. A total dose of 2000 cGy in 10 fractions was administered in 2 weeks. Factor VIII was not given. After 4 months, complete healing was seen. The patient was followed up at 24 months, and there was no evidence of recurrence and no bone growth disturbance. Based on our experience and a review of the literature, radiotherapy can be an effective alternative modality in treating hemophilic pseudotumor.

Osseous lipoma: eleven new cases and review of the literature.

This study describes the clinical features, radiological appearance, and treatment of 11 new cases of osseous lipoma and reviews 301 other cases in the literature. Osseous lipomas are classified by the site of origin: either within bone (intraosseous lipoma) or on the surface of bone (juxtacortical). Intraosseous lipomas include intramedullary and intracortical lesions. Surface lipomas include subperiosteal and parosteal lesions. The authors added their cases to those found in the literature. Intramedullary osseous lipoma (n=262) : the most common presenting symptoms were pain and swelling (69%). The most frequent localisations were the calcaneus (24%) and the femur (22%). On plain radiographs, these lesions consisted of a well-circumscribed radiolucent area with central calcification and a sclerotic rim, occasionally with cortical expansion. Computed tomography (CT) and magnetic resonance imaging (MRI) showed that the lesions had attenuation values and a signal intensity identical to that of adipose tissue. In symptomatic lesions and in cases with impending fracture, operative treatment was indicated. Parosteal lipoma (n=47): the most common presenting symptoms were local swelling and pain (58%). This lesion was most frequent in the radius (31%) and in the femur (23%). The classic radiographic appearance of parosteal lipoma was that of an exostosis-like bony prominence capped with a radiolucent layer of fat. CT-scan and MRI showed similar features. Intracortical (n=2) and subperiosteal lipomas (n=11): only a few cases were found in the literature. Their localisation differs from that of the other osseous lipomas. The differential diagnosis of osseous lipoma in general is extensive and should include benign and malignant tumours. Combination of radiological and histological data is essential to determine whether an osseous lipoma is actually present.

Technique and complications of callus distraction in the treatment of bone tumors.

INTRODUCTION: This study investigated the effects of chemotherapy, defect length, and patient age on the outcome and complications of callus distraction as a limb salvage technique in 17 patients. MATERIALS AND METHODS: The mean patient age was 18.4 years (range 7-47). Of 17 patients, 8 received chemotherapy and the remaining 9 patients did not. The mean defect length after excision of the lesion was 13 cm (range 8-20). The mean follow-up period for the patients whose treatments were completed was 55 months (range 20-90), the mean distraction index was 12.55 days/cm (range 11-15.7), and the mean external fixation index was 34.73 days/cm (range 30-41). RESULTS: In two patients, local recurrence occurred before distraction was completed. Two patients died, and one of them was a patient in whom local recurrence had occurred. Complications included non-union in one patient, osteomyelitis in one patient, and premature callus, osseous bridge, and varus of the femur in one patient. The extremity functional score was 80% (range 26-100). Chemotherapy and defect length had no significant effect on the distraction or external fixation indices. In contrast, the increase in the external fixation index in those over 20 years old was significant (P=0.043). CONCLUSION: We found that chemotherapy and defect length have no significant effect on the outcome and complications with this technique, which was more successful in patients younger than 20 years.

Tuberculosis of the shoulder joint.

OBJECTIVES: Skeletal tuberculosis is less common than the pulmonary form. The involvement of the shoulder joint is infrequent. We report our experience treating tuberculosis of the shoulder in 11 patients. METHODS: There were seven men and four women, ranging in age from 19 to 55 years (average 28.09 years). The duration of their complaints at presentation ranged from 3 to 24 months. The most common presentation was pain, which was seen in 10 joints. All of the patients had mild to moderate restriction of motion of the shoulder. On laboratory examination, the erythrocyte sedimentation rate was increased mildly. No patient had an active tuberculosis lesion or history of pulmonary disease. The diagnosis was based on the clinical picture and radiographic features, and was confirmed by open biopsy. The diagnosis was not confirmed by biopsy in one patient, but the family history and clinical and radiological features were highly suggestive of tuberculosis. Surgical debridement was done in two patients and open biopsy in eight patients in order to obtain samples for pathology. Arthrodesis was done in only one patient. In all patients, treatment began with a four-drug regimen for 2 months, followed by a two-drug regimen for 10 months. RESULTS: The mean follow-up period after the end of treatment was 28.72 months (range, 22-52 months). At the time of the last visit, all the lesions had healed without recurrence. Five cases had a painless, mobile shoulder, while three had mildly restricted shoulder motion without pain, and three had residual limitation of motion of the affected shoulder. CONCLUSIONS: Tuberculosis of the shoulder can be difficult to diagnose in the early stages. If not diagnosed early, bony tuberculosis may reduce the quality of life. Therefore, tuberculosis should be suspected in cases of long-standing pain in the shoulder. It is necessary to keep tuberculosis in the differential diagnosis of several osseous pathologies. Arthrodesis should be reserved only for lesions that fail to heal after adequate chemotherapy and rehabilitation.

Tuberculosis of the metacarpals and phalanges of the hand.

Skeletal tuberculosis (TB) is less common than the pulmonary form. Involvements of the metacarpals and phalanges of the hand are infrequent. The authors report their experience with treatment and outcome of TB of the metacarpals and phalanges of the hand in 7 patients. There were 4 women and 3 men in the study who ranged in age from 3 to 60 years (average age, 22.7 years). The duration of complaints at presentation ranged from 4 to 17 months (average, 9 months). The most common presentation was pain and swelling. The presumptive preoperative diagnoses were bone tumor in 4 patients, spina ventosa in 2, and chronic pyogenic osteomyelitis in 1 patients. The results of the laboratory examination showed a mild increase in the erythrocyte sedimentation rate. No patient had an active tubercular lesion or history of pulmonary disease. The diagnosis was based on the clinical picture and radiographic features, and was confirmed by open biopsy. No patient had bony debridement or arthrodesis to control the infection. The treatment of all patients began with a 4-drug regimen for 2 months, followed by a 2-drug regimen for 10 months. The mean follow-up was 30.28 months (range, 16-52 months). At the time of the last follow-up, all lesions had healed with no recurrence. The functional results were satisfactory in all patients. One patient with thumb metacarpophalangeal TB had joint irregularity and thumb metacarpal shortening. Arthrodesis was not needed in any patient. TB of the metacarpals and phalanges of the hand can be difficult to diagnose during the early stages. TB should be suspected in cases of long-standing pain and swelling in the metacarpals and phalanges. It is necessary to keep TB in mind when making the differential diagnosis of several osseous pathologies.

Giant-cell reparative granuloma of the tibia.

Giant-cell reparative granuloma (GCRG) occurs in the jaw, temporal bone, and short tubular bones of the hands and feet. Although GCRG can affect long bones, only small numbers of such cases have been sporadically reported. This report describes a giant-cell reparative granuloma in the proximal tibia in a 60-year-old woman, describes features of GCRG in long bones and reviews the literature. A 60-year-old female patient was referred to us with complaints of moderately tender swelling of the right leg. Whole-body scintigraphic scanning was performed, which incidentally also disclosed a distal femoral lesion. The patient was admitted for surgery and incisional biopsies were performed on both lesions. Pathology analysis of the specimen from the tibia showed new bone lamellae encircled by osteoblasts and multinucleated giant cells which were more numerous in the haemorrhagic regions of the stroma; the latter displayed fibroblasts, histiocytes and inflammatory cells. The specimen from the femoral lesion showed typical features of a benign enchondroma. The patient was readmitted for surgery. The femoral enchondroma was curetted and the cavity was packed with bone graft. The tibial GCRG was treated with marginal resection, autogenous and allogenous bone grafting and intramedullary nailing. Follow-up examination after two years showed no clinical or radiological evidence of a recurrence. Although GCRG is uncommon, it should be considered whenever a lucent, expansile, and possibly destructive lesion of a long bone is encountered. It should be distinguished from true giant cell tumours occurring in the same locations because they have different biologic behaviours.

Problem fractures associated with gunshot wounds in children.

Twenty-seven fractures in 22 children (14 female, 8 male; average age: 10.5) who suffered gunshot wounds were retrospectively evaluated. Fourteen of the fractures were caused by high-velocity weapons, four by low-velocity weapons, and nine by shotguns. One of the fractures was undisplaced, two were displaced, 10 were comminuted, seven were comminuted and displaced, and seven had bony defects. Accompanying pathologies included four physeal, three articular, four visceral, four arterial, six peripheral nerve, and one spinal cord injury. Initial treatment involved external fixation in 15 patients and internal fixation in one patient for bone stabilization, while the remaining patients were treated conservatively.Late-stage surgery was necessary to achieve soft-tissue coverage in three patients and to achieve union in six patients. Major complications included amputation in one patient, non-union in two, delayed union in one, osteomyelitis in one, paraplegia in one, and loss of peripheral nerve functions in three. The treatment of fractures associated with firearm injuries in children is never simple. Fracture defects, accompanying peripheral nerve damage and involvement of the joint negatively is affect the outcome, increasing the chance that late-stage surgery will be necessary. Internal bone transport appears to be an efficacious technique in the treatment of bone and soft-tissue defects associated with firearm injuries in children.
