The purpose of this study is to present the preliminary results after treatment of shoulder sepsis with prolonged implantation of an antibiotic-loaded cement spacer in a selected group of compromised patients.

The current study included 11 patients (9 males and 2 females) with a mean age of 64 years (range: 36–79 years). All patients were treated with radical debridement, implantation of an antibiotic-impregnated polymethylmethacrylate spacer, and 6 weeks of antibiotic therapy. The subjective complaints, range of motion of the shoulder, functional outcome (mini-DASH score), and radiographic findings were evaluated. Nine patients at a mean follow-up time of 21 months (range: 13–18 months) were free of infection with pain relief and adequate shoulder function for activities of daily living. Radiographic evaluation revealed no loosening or fracture of the spacer and no progressive degenerative changes involving the glenoid.

Prolonged implantation of the spacer may be a useful alternative in selected patients with poor general condition.

Introduction: To assess the value of MR imaging (MRI) with regard to union, graft viability and proximal pole bone marrow status, after use of vascularized bone grafts (VBG) for treating scaphoid nonunions (SN).

Methods: VBG from the distal radius were used to treat 52 SN. Clinical and imaging evaluation was used for the pre- and postoperative assessment of all patients. Apart of radiographs obtained in all cases, 19 patients were also assessed postoperatively with MRI at 3 months (15 of 19 were assessed preoperatively with MRI) and 15 had serial MRI evaluations (6–12 months). The clinical follow-up time of this subgroup of 19 patients ranged from 6 to 27 months.

Results: All patients showed clinical signs of union within 12 weeks from the procedure. 3-months MRI showed viability of the bone graft in all cases. At 3 months union was established with plain radiographs in 14 patients; plain MRI showed union in 13 patients but contrast-enhanced MRI revealed union in all cases. Eight patients were considered to have osteonecrosis of the proximal pole intraoperatively: 4 showed proximal pole necrosis with postoperative plain radiographs and 5 of them with plain postoperative MRI. Contrast-enhanced MRI at 3 months showed postoperative reversal of necrotic changes in all 8 scaphoids. Serial MRI at 6 and 12 months, revealed resolution of the bone marrow oedema of the surrounding bones and full graft incorporation in all cases.

Conclusions: Contrast-enhanced MRI is able to assess the viability of the proximal pole and to demonstrate the early union after treatment of SN with VBG allowing thus earlier mobilisation.

Purpose: To evaluate the differencies in graft orientation between transtibial and anteromedial portal technique using magnetic resonance imaging (MRI) in anterior cruciate ligament (ACL) reconstruction.

Materials and Methods: Fifty one patients who undergoing arthroscopically ACL reconstruction underwent MRI of their reconstructed knee. Thirty patients had ACL reconstruction using the transtibial technique (group A) while in the rest 21 the anteromedial technique (group B) was used. In the femoral part graft orientation was evaluated using the femoral graft angle (FGA). The FGA was depicted at the coronal views by two axes: the anatomical axis of the femur and the axis of the femoral tunnel. In the tibial part graft orientation was evaluated using the tibial graft angle (TGA). The TGA was specified as the angle between the axis of the graft and a line parallel to the tibial plateau at the sagittal view.

Results: The mean FGA for group A was 12.52° while for the group B was 27.06°. This difference was statistically significant (p< 0.001 paired t-test). The mean TGA for group A was 64.24° while for the group B was 63.11° but this was not statistically significant.

Conclusions: Using the anteromedial portal technique the ACL graft is placed in a more oblique direction in comparison with the transtibial technique in the femoral part. This may have an impact in rotatory knee stability. However, there are no differencies between the two techniques in graft orientation in the tibial part.

Background: Clinical tests used for the detection of knee meniscal tears do not present acceptable diagnostic sensitivity and specificity values. Diagnostic accuracy is improved by arthroscopic evaluation or performing magnetic resonance imaging (MRI) tests. The objective of this study was to evaluate the diagnostic accuracy of a new dynamic clinical examination test for the detection of meniscal tears.

Methods: Two hundred and thirteen symptomatic patients with recent knee injuries who all were clinically examined, had MRI tests and underwent arthroscopic surgery and 197 asymptomatic volunteers who all were clinically examined and had MRI tests of their normal knees were included in this study. For clinical examination the medial and lateral joint line tenderness test, McMurray test, Apley compression and distraction test, Thessaly test at 5° and Thessaly test at 20° of flexion were used. For al clinical tests sensitivity, specificity, negative predictive value and diagnostic accuracy rates were calculated against arthroscopic and magnetic resonance imaging data.

Results: Thessaly test at 20° of flexion showed a high diagnostic accuracy rate at the level of 94% and a low number of false negative recordings in detecting tears of both the medial and lateral meniscus. Other traditional clinical examination tests, with the exception of joint line tenderness which presented a diagnostic accuracy rate of 88% in detecting lateral meniscal tears, showed inferior rates.

Conclusions: Thessaly test at 20° of flexion can be safely used as a first line screening clinical test for the detection of meniscal tears reducing the need and the cost of modern magnetic resonance imaging methods.

Purpose: The aim of this study was to document donor site problems one year after anterior cruciate ligament (ACL) reconstruction and to compare the differencies between hamstring and patellar tendon autografts.

Materilas and Methods: Sixty-four patients undergoing primary arthroscopically ACL reconstruction were randomized to have a central third bone patellar tendon bone (PT) autograft (30 patients) or a doubled semiten-dinosus/doubled gracilis (HS) autograft (34 patients). The postoperative rehabilitation regimen was identical for both groups. All patients were examined one year postoperatively. Objective parameters evaluated included pre and postoperative IKDC and Lysholm score, side-to-side KT-1000 maximum-manual arthrometer differences. The Shelbourne score was used to evaluate anterior knee symptoms. Loss of sensitivity in the anterior knee region postoperatively as well as scar sensitivity were also recorded.

Results: Three patients (10%) in the PT group had anterior knee symptoms while only one (3%) in the HS group. The mean Shelbourne score was 98 for the HS group and 93 for the PT group but this was not statistically significant. However, 8 pateints (23%) had disturbed sensitivity in the anterior knee region in the HS group, but none in the PT group and this was statistically significant (p< 0.005). Scar sensitivity was present in 3 patients (10%) in the PT group and in one (3%) in the HS group. No differencies were found postoperatively between the groups regarding IKDC, Lysholm score and side-to-side KT-1000 measurements.

Conclusions: Although,notstatisticallysignificantpatients in the PT group had more anterior knee symptoms and scar sensitivity, one year postoperatively. In contrast, harvesting of hamstring tendons produces significantly more sensory nerve complications in the anterior knee region than harvesting the middle third of patellar tendon. Both grafts seem to improve equally patients’ performance.

Purpose:In this study we investigated the MRI þndings of healing process after arthroscopic meniscal repair. Methods and Materials: 15 patients with buckethandle medial meniscal tears were operated arthroscopically within 3 weeks after injury. All had accurately diagnosed meniscal tear with preoperative MRI. Six patients had an additional anterior cruciate ligament tear, also primarily reconstructed with the meniscal repair. The MR examination was perfrormed with a 1 T scanner, applying the following pulse sequences: T1-w Spin Echo (SE), PD-w Turbo Spin Echo (TSE) with fat suppression, T2-w TSE and T1-w SE in coronal and axial plane after iv administration of paramagnetic contrast agent. The postoperative MRI examinations were performed in 3 weeks intervals starting at the 6th postop and till the 18th , and 6 weeks thereafter. All patients were asymptomatic postoperatively. Results:Grade III and IV signal alterations were present on all MRI scans. Contrast enhanced images showed in addition: a) signal alterations extending through the path of suture out of the meniscus, b) enhancement of the medial collateral ligament simulating injury and c) synovitis in all patients. In one patient examined sequentially, the contrast-enhanced images demonstrated that a and b decreased after 3 months and synovitis was no more evident. Conclusion:Contrast enhanced MRI is the method of choice for demonstrating the normal healing process of the arthroscopic meniscal repair in bucket-handle tears. A gradually disappearing of the abnormal enhancement is related to scar tissue rather than to meniscal retear.

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.

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.
