Introduction: Osteomyelitis and septic arthritis (SA) below the elbow are severe conditions affecting the function and viability of the hand. Factors predisposing to these conditions and parameters affecting prognosis are emphasized.

Material and Methods: In a 4 years period, 16 patients with SA (4) or osteomyelitis (12) were treated in a University Orthopaedic Department providing care to a rural population of 1.000.000, Nine had history of trauma in unhygienic environment, 3 had immunodeficiency and in 4 osteomyelitis was iatrogenic [previous fixation of fractures (3) and vein catheterization (1)]. SA was located in the wrist (2) and thumb joints (2) and osteomyelitis involved the radius (3), ulna (1), metacarpals (3) and phalanges (5). Ten patients received oral antibiotics in other centers. The mean delay from onset of symptoms to referral to our center was 22 days. Apart of antibiotics administration, surgical treatment included debridement and irrigation for SA and excision of necrotic bone, stabilization (external fixators), use of antibiotic beads and secondary bridging with bone graft for osteomyelitis. Additional procedures (amputations, arthrodesis) were also required in some cases.

Results: Cultures were positive in 9 of 16 cases [Staph. aureus (5) and enterobacter cloacae (3)]. Patients underwent multiple procedures (mean: 3.8) and 4 underwent amputation of a digit (2) and hand (2) due to the rapid extension of infection threatening and finally taking the lives of 2 elderly and immunosuppressed patients. Mean follow-up period of the 12 surviving and non-amputated patients was 18 months. Union was accomplished in all cases. Functional results were excellent or very good in 10 of 12 patients and good in 2 patients. All patients were satisfied and returned to their previous occupations.

Conclusions: Osteomyelitis and SA below the elbow was frequent in population living in unhygienic environment or working with soil. All cases received medical treatment with delay. Immunosuppressing conditions favored the extension of infection and threatened patients lives. Delay in treatment in combination to immunosuppression resulted to significant morbidity. Early treatment including surgical drainage, thorough debridement and antibiotic administration is necessary for elimination of skeletal infection and salvage of the hand and patients life.

We investigated the effect of calcitonin in the prevention of acute bone loss after a pertrochanteric fracture and its ability to reduce the incidence of further fractures in the same patient.

Fifty women aged between 70 and 80 years who had a pertrochanteric fracture of the hip were randomly allocated to group A (200 IU of nasal salmon calcitonin daily for three months) or group B (placebo).

Patients in group A showed a significantly higher level of total alkaline phosphatase and osteocalcin on the 15th day after injury and a significantly higher level of bone alkaline phosphatase on the 90th day after surgery. These patients also had significantly lower levels of urinary C-telopeptide (CrossLaps) on the 15th, 45th and 90th days after injury and lower levels of urinary hydroxyproline on the 15th and 45th days after injury. Patients in group A had significantly higher bone mineral density at all recorded sites except the greater trochanter at three months and one year after operation. After a four-year period of clinical observation, five patients (24%) in group B sustained a new fracture, in four of whom (20%) it was of the contralateral hip.

Our findings show that calcitonin reduces acute bone loss in patients with pertrochanteric fractures and may prevent the occurrence of new fractures of the contralateral hip in the elderly.

Aim: To evaluate long term effects of stress shieldieng phenomenon after cementless total hip arthroplasty. Materials-Methods: 80 female pts with OA were randomly allocated in 4 groups according to the type of the cementless stem which was primarily implanted (A-Zwey-Muller,B-Corail,C- Optifix,DAutophor900S). BMD changes of the operated hip (in seven zones), of the operated, contralateral normal hip and of the Lumbar spine were measured pre-op, at 2, 8 and 12 months and every year thereafter. Results: At ten years, 72 pts were available for follow up, all with satisfactory clinical and radiological results with no evidence of polyethylene wear or endosteal lysis. In all groups, the greatest reduction of BMD (calcar atrophyzone 7) was observed at the 2nd post-op year (A:24%, B:8%, C:14.8%, D:18.5%). In all groups, the greatest increase (zone 4) of BMD was also observed at the 2nd post-op year (A7%, B2%, C2.5%, D6.3%). In all groups a similar pattern of slow but progressive recovery of bone mineral density changes after the 3rd year was observed in both zones, approaching baseline values at 10 years in all groups. Preoperative lumbar BMD (osteopenia), body weight, sex and height were not statisticaly correlated to calcar atrophy. Conclusions:We suggest that the clinical and theoretical relevance of stress shielding phenomenon in total hip replacement has been overestimated in the literature

Aims: To assess morbidity and the long term sequellae following multiple compartment syndrome of the tibia. Methods: We prospectively followed 21 referred patients (pts). Syndromeñs etiology, the socioeconomic consequences and the way the condition affects the quality of patientsñ lives were evaluated. Patientsñ morbidity, the number and the severity of the reconstructive operations were assessed. A subjective SF-36 evaluation was also performed. Results: The aetiology of the syndromes was RTA in 13 pts, accident at work in 7 and in 1 patient the result of an osteotomy and external þxation. Late release of the compartments was performed in 9 pts. In the remaining 2 pts release was performed at onset. The consequences were drop-foot in 14 pts, club foot in 2, cavus foot in 8, clawing of toes in 14, ankle stiffness in 7, plantar numbness and anesthesia in 13, plantar callosities in 5 and chronic infection in 8. Effective management involved 1–10 subsequent reconstructive procedures in the following 1 to 5 years with hospitalization ranging from 35 to 360 days. One patient was amputated. Two pts were able to perform an easy job and only those 2 in whom the compartments were released in time returned to previous occupations. The remaining are currently unemployed. Conclusions: Established compartment syndromeñs effects on soft tissue and bone seriously affect limb function, permanently impair quality of the patientñs life and deprive them from working effectively. These þndings emphasize the importance of early diagnosis and prompt release.

Aim: Evaluation of intermediate clinical and radiographic results of displaced intra-articular fractures of the calcaneus treated with ORIF. Materials- Methods: From 1994 to 2002, 167 displaced intra-articular fractures of the calcaneus were treated with ORIF. There were 145 male and 12 female patients. Mean age 34 years. Standard x-rays, Broden views and CT-scan images in coronal and transverse plane were obtained pre and post operatively. Fractures were classified as type III, IV, V according to Sanders. All fractures were approached through an extended lateral L-type approach. AO calcaneal plate was used. Average follow-up was 5 years. Results: In 143 Sanders type III and IV fractures KITA-OKA score was 91. Reduction failure rate was 5.5%(8 pts). 24 patients had Sanders type V fractures and KITAOKA score was 84 and reduction failure rate was 25% (6 pts). 29/167 patients complained of peroneal tendons tenderness which subsided after hardware removal. 79/167 patients had restriction of subtalar joint movements but no complains (SF_36) There were two superficial wound infections and five patients with delayed wound closure. In a group of 45 patients with similar fracture patterns who were treated conservatively, KITA-OKA score was 71, 41 fractures were malunited, 40 patients had moderate to severe pain and early OA sings. Conclutions: Displaced intra-articular fractures of the calcaneus should be treated as any other displaced intra-articular fracture, with open reduction and stable internal fixation

Aim: Tissue injury leads to platelets migration and release of growth factors (GF): Platelet-Derived GF (PDGF) and Transforming GF-beta (TGF-b) that are particularly important for the bone repair process. The purpose of our study is to evaluate the new bone formation with the use of AGF-bone graft combination and to estimate the concentrations of PDGF-AB and TGF-b2 during the procedure.

Methods: AGF-bone graft combination was used in 34 patients with long bone defects (24) and spinal fusion (10). TGF-b2 and PDGF-AB concentrations were assessed in samples from blood. Aliquots were taken at each stage of AGF preparation (whole blood, buffy coat, AGF, wound drain) and analyzed for TGF-b2, PDGF-AB concentration and platelet counts. ELISA was performed to quantify concentrations of active PDGF-AB and TGF-b2. Postoperative evaluation was clinical and radiological (radiographs, tomograms, QCT).

Results: Mean follow up time was 9 months. Signs of bone union were apparent in radiographs 3–6 months after the index procedure. Average platelet count increased from 212x106 cells/ml to 680x106 cells/ml (buffy coat) and to 1280x106 cells/ml (AGF concentrate), resulting in a 604% increase. A 480% increase of PDGF-AB levels and a 320% increase of TGF-b2 levels in AGF concentrate comparing to whole blood levels was determined. TGF-b2 and PDGF-AB levels were also detected in samples collected from the wound drains, in increased levels comparing to the AGF concentrates.

Conclusions: In all cases the clinical results were very encouraging with augmented osteogenesis, whereas the laboratory results (increased values of TGF-b2 and PDGF-AB in subsequent stages of the procedure) practically predicted the clinical success.

Purpose: We present the results of subacromial decompression and repair of the rotator cuff through a minimal deltoid-on approach.

Material and Method: Eighty-seven patients with longstanding shoulder pain were evaluated in two years (1999–2000) in our department. In sixty -eight of them symptoms were due to impigment syndrome. Eight patients with follow up time less than six months were excluded from this study, twenty were treated conservatively and the remaining forty (22 female, 18 male, mean age 50.3) underwent surgery. Three x-ray views were obtained in all patients, i.e. standard AP, true AP, and subacromial space projection. MRI was also obtained in all patients. MRI revealed calcific tendinitis in fifteen patients, osteophytes of the acromioclavicular joint in thirteen, a hooked (type III) acromion in ten and partial tear of the supraspinatus tendon in nineteen. In five of them there was also a partial tear of the infraspinatus. Finally, seven patients were suffering of a full thickness tear of the supraspinatus tendon. All patients were operated through a minimal deltoid-on approach. Acromioplasty and coracoacromial ligament dissection was performed in all. In patients with osteoarthritis of the acromioclavicular joint, osteophytes were carefully removed. Calcific deposits were also removed in all patients. In eighteen patients tears of the rotator cuff were detected and repaired using bone anchors.

Results: All patients were examined six months postoperatively. Results were evaluated with CONSTANT SCORE and with a questionnaire for patient’s satisfaction. Thirty-seven patients were very satisfied with the result and three were satisfied. As for Constant score, pain improved at an average of 7.8 points, daily activities by 5.4, and range of movement by 4.2 points. Results were evaluated by the examiner as excellent in thirty-six patients (90%) and very good in four patients.

Conclusion: Deltoid-on approach, in patients with impingement syndrome of the shoulder provides adequate exposure for the surgical repair with minimal trauma and a very low rate of complications.

Background: We present our further experience with the Orthofix tibial nailing system, concurrently evaluating the easy and safety of the distal targeting system for the distal locking.

Materials & Methods: Ninety-seven fresh tibial fractures in the same number of patients with a mean age of 38,5 years (17–85) were treated. Three were lost from the follow-up. Twenty of the fractures were grade I open fractures, four grade II and one grade IHA. All operations were performed in a conventional operating theater on a simple transparent operating table, with reduction of the fracture performed under manual traction and manipulation of the fracture site, hi most of the cases closed reduction was achieved and conventional reaming performed; in 14 patients the fracture was reduced through a small incision at the fracture site. Conventional reaming (power reaming) was performed in 69% of the patients; however, in 31% of the cases (30 patients), only minimal hand reaming was performed. The mean duration of the operation was 30 min. The external targeting device failed in 10 distal locking screws, in six of which the second attempt was successful. In four an image intensifier had to be used.

Results: Fracture healing, confirmed clinically and radiographically, was observed at a mean of 17 weeks (12–28 weeks). No tibial non-union necessitating reoperation occurred, however six fractures showed delayed union. Open reduction didn’t compromise the healing of the fracture. All patients eventually gained a full range of motion knee and ankle joint and only twelve of them (12%) complained of mild anterior knee pain. All patients returned to their previous activity, except for one disabled from a head injury. The later evaluation showed preservation of the tibial axis in all patients and additionally that no mechanical failure of either the nail or the screws occurred.

Conclusions: We conclude that the Orthofix nailing system is a clinically effective system. Distal locking can be performed with ease without significant exposure to radiation, provided that the operative technique is accurately followed, the nail is inserted without significant force and the distal targeting device is not subjected to any violation, such as hammering.

We evaluated the clinical outcome of IM nailing for the treatment of femoral shaft pseudarthrosis in patients who had multiple failed plate osteosyntheses. From January 2000 untill April 2001, 20 (19 male-1 female, mean age 28) patients were treated because of femoral shaft non-union in our institution. All patients had two or more failed plate osteosyntheses. There were no septic non-unions in this group. Eight patients had an established non-union on an average of nine months post-op and the remaining eleven had radiological and clinical evidence of implant failure. There was no segmental bone loss, hi all patients the implants were removed and nailing was performed. Extensive periosteal stripping, bone necrosis and soft-tissue scaring were constant findings in all patients. Twelve patients received interlocking nails. Eight femurs were grafted with iliac crest bone graft. All patients were followed by serial x-rays until union.

There were no postoperative complications. All pseudarthroses were healed within an average of 9.7 months (8–12). Non-unions which received bone graft (eight out of twenty) in day one, were healed faster than those which didn’t. There were no re-operations among these patients. Among the remaining ten patients five were grafted five to six months postoperatively and three had had nail dynamization.

IM nailing for femoral shaft non-unions after multiple failed plate osteosyntheses is a safe and effective method of treatment. Autologous bone graft reduces healing time and re-operation rate.

Purpose: The efficacy of nasal salmon calcitonin (CT) in preventing bone loss after a hip fracture and in reducing the incidence of further contralateral hip fractures was evaluated.

Material and Methods: Fifty women aged 70–80 years who sustained a pertrochanteric fracture were randomly allocated to Group A (200 IU of nasal salmon calcitonin daily for three months) and Group B (placebo). Biochemical bone markers (1st, 7th, 15th, 45th and 90th day post injury) and bone mineral density of the lumbar spine and the intact contralateral hip (4th and 90th postoperative day, and one year after the fracture) were measured.

Results: Patients in the calcitonin group showed statistically significantly higher total (p< 0,005) and bone alkaline phosphatase (p< 0,002) and osteocalcin (p< 0, 05) levels on the 15th day, while statistically significantly lower uCTX values on the 15th (p< 0,045), 45th (p< 0,002) and 90th (p< 0,002) day and uHpr/Cr values on the 15th (p< 0,015) and on the 45th (p< 0.05) day post injury. In the placebo group patients showed a statistically significant reduction (all p values < 0.05) of bone density values at 3 months and one-year post surgery while in the calcitonin group no significant changes from baseline. When the two groups were compared, patients in the calcitonin group showed statistically significantly higher bone mineral density values (all p values < 0.05), in all recorded sites, at 3 months and one-year post operatively. After a four years clinical follow-up, five patients (5/25, 20%) sustained a new fracture of the contralateral hip in the placebo group.

Conclusion: Nasal salmon calcitonin prevented early bone loss in these patients and may have a protective role on the occurrence of a new fracture of the contralateral hip in the same patient.

We report a prospective case-controlled study which compared the outcome of knee replacement in seriously deformed and slightly deformed knees. There were 51 knees with varus or valgus deformity greater than 20 degrees matched for age, gender, disease, type of prosthesis and time of operation with a control group in which the alignment of the leg was within 5 degrees of normal. The clinical outcome at a mean 5.5 years was similar in the two groups. Some deformity persisted in 14 patients in the first group, 13 of whom were initially in valgus. These patients had a significantly poorer mean clinical outcome. Lateral dislocation or subluxation of the patella was found in four knees, all of which had had valgus deformity of 30 degrees or more.

We describe the use of intramedullary reconstruction nails in the treatment of 14 patients with pathological subtrochanteric fractures and coexisting metastases in the femoral shaft. After nailing, all patients were free from pain and regained mobility. They were followed up clinically and radiologically until death from the primary disease. There were no mechanical failures even when a less than ideal reduction had been achieved.
