One hundred and twenty-four patients who had undergone arthroscopic repair of rotator cuff tear, during the period of 2006–2008, were evaluated. All operations were performed under the same surgeons. The mean follow-up period was 1.1±0.4 years (range, 0.5 to 2 ys). The patients were devided in three groups:

patients underwent complete repair (n=104),

patients underwent incomplete repair (n=8) and

patients underwent medialized technique repair (n=12).

Clinical outcomes preoperatively and postoperatively, were assessed with use of ASES, CONSTANT and UCLA scores. Statistical analysis was performed by using STATA 8.0.

Postoperative functional scores were better than preoperative ones, in all patients (p< 0.05).The patients underwent complete repair achieved preoperatively Constant score: 58.15±3.26, ASES score: 55±3.6, UCLA score: 22.3±1.2 and postoperatively Constant score: 92.65±4.15, ASES score: 92±2.4, UCLA score: 32.1±1.3. The patients underwent incomplete repair achieved preoperatively Constant score: 46.18±3.12, ASES score: 44.2±3.4, UCLA score: 18.1±3.3 and postoperatively Constant score: 76.35±4.22, ASES score: 72±5.4, UCLA score: 24.1±2.3. The patients underwent medialized technique repair achieved preoperatively Constant score: 52.3±1.12, ASES score: 51.9±2.4, UCLA score: 20.4±1.3. and postoperatively Constant score: 86.15±2.22, ASES score: 85.4±4.4, UCLA score: 28.24±2.3. Significant difference was observed between (a) and (b) groups (p< 0.05, CI1: 0.83–0.97, CI2: 0.86–0.95, CI3: 0.81–0.97).

Functionality improvement after arthroscopic repair of rotator cuff tear, with complete, incomplete or medialized repair either, is evidence.

To evaluate the incidence of early complications and operative events during shoulder arthroscopy.

A prospective study of 134 consecutive shoulder arthroscopies, performed using lateral decubitus position, by the same team, with 6 months minimum follow up. During 11 months period we performed 80 shoulder arthroscopies in male and 54 in female patients with mean age 48.6 years (15–82 years). Shoulder pathology that we treated was: 74 rotator cuff repair, 37 shoulder instability, 11 frozen shoulder, 9 calcifying tendonitis, 2 SLAP lesion and 1 debridement. We have well-placed 476 anchors and 63 side to side sutures.

We experience 4 early complications in total (2.98%): 1 anterior interosseous nerve paresis, that fully recovered 6 weeks post op, 1 motor and sensor ulnar nerve paresis that has not fully recovered 4 months post op, 1 sensor ulnar nerve paresis that has not fully recovered 5 months post op and 1 septic shoulder arthritis that was treated with arthroscopic lavage and intravenous antibiotics and has not shown recurrence 11 months post op.

Operative events: 5 (1.05%) anchor slippage, 3 (0.63%) anchor breakage, 5 (0.53%) suture slippage from anchors, 5 (3.73%) instrument breakage, 5 (0.53%) knot loosening or suture breakage.

Shoulder arthroscopy is a quite safe but technically demanding operation. Early complications occur in low rate, but due to technical difficulties operative events occur more frequently, without affecting the final outcome of the operation. Although axillary nerve is believed to be prone to injury during shoulder arthroscopy, in this series other neurological lesion occurred more frequently.

To evaluate humeral and glenoid bone loss in patients surgically treated for shoulder instability as factors of recurrence.

During the period 2000–2008, 114 patients (103 men and 11 women) with mean age of 28 yrs underwent arthroscopic treatment for shoulder instability by the same surgeon. Mean age of the 1st shoulder dislocation was 20,89 yo and the average number of dislocations per patient was 17,14. Glenoid bone loss was found in all patients (16 Large, 59 Medium, 29 Small), as well as Hill Sachs lesions (66 Large, 23 Medium, 8 Small) or both. Thirteen (13) patients had an “inverted pear” glenoid shape. Seventy five (75) were into sports and for 57 (76%) of them this involved Overhead/Contact activities. Also 20 patients presented joint hypermobility. Complete follow up existed for 92 patients and it ranged from 4–108 months (Mean=44). The recurrence of instability and the functional outcome were evaluated post-op using the Rowe Zarins Score.

Recurrence of instability was noted in 5 patients (4,38%). All of them presented Hill Sachs lesions and glenoid bone loss (2 Large, 2 Medium, 1 Small) but without an “inverted pear” glenoid shape or joint hypermobility. All 5 of them were into Overhead/Contact sports activities (2 Professional: Mean=15hr/w and 3 Amateur: Mean=2,5hr/w). The post op Rowe Zarins Score ranged from 80–100 (Mean=95,11).

From the evaluation of our data, it seems that humeral and glenoid bone loss do not significantly contribute to the recurrence of arthroscopically treated shoulder instability.

This paper aims to evaluate the Remplissage arthroscopic technique as described by Eugene Wolf used in patients with traumatic shoulder instability that present glenoid bone loss and Hill Sachs defects.

In our study 28 patients (5 women and 23 men) with mean age of 31 yrs underwent arthroscopic stabilization of the shoulder by the same surgeon during 2007–2008 period. All patients presented Hill Sachs lesion, 11 of them had medium or large glenoid bone loss, 10 had an “inverted pear” glenoid shape, 4 had been revised for stabilization in the same shoulder and 14 presented joint hypermobility. Mean age for the age of 1st dislocation was 20,1 yrs and our follow up ranged from 5–28 months (Mean=18). The recurrence of instability and the functional outcome were evaluated pre-op and postop with the Rowe Zarins Score. The post op rehabilitation was performed by a specialist.

None of the patients presented recurrent instability. The Rowe Zarins Score raised from a mean pre op score of 23,33 (15–60) to a mean post op score of 97,11 (75–100) (p< 0.05). All the patients that were into sports activities before the presentation of shoulder instability began training again and our post op evaluation of the shoulder’s ROM showed a decrease in the external rotation from 0°–15°.

The infraspinatus tenodesis and posterior capsulodesis in patients with humeral bone loss seems to offer so far excellent post op results despite the slight decrease in the external rotation of the shoulder.

To analyze the relationship between functional outcome and tissue quality after arthroscopic rotator cuff repair.

One hundred and forty-five patients who had undergone arthroscopic repair of rotator cuff tear, during the period of 2003–2008, were evaluated. All operations were performed under the same surgeons. The mean follow-up period was 2.4±1.2 years (range, 0.5 to 5 ys). The patients were devided in two groups:

patients with good tissue quality and

patients with poor tissue quality.

As good tissue quality is defined the tendon with enough mass for suturing (thickness> 3mm) and good elasticity (the footprint is covered properly under tendon traction with tissue grasper). The independent variable studied here was the tissue quality of rotator cuff tendon. Clinical outcomes preoperatively and postoperatively, were assessed with use of ASES, CONSTANT and UCLA scores. Statistical analysis was performed by using STATA 8.0.

Good tissue quality was identified in 119 patients (82%) and poor tissue quality in 26 (18%) patients respectively. At the follow up the patients with good tissue quality achieved Constant score: 86.85±12.49, ASES score: 84±3.4, UCLA score: 28.7±1.9 and the patients with poor tissue quality achieved Constant score: 62.35±13.85, ASES score: 61.49±8.9, UCLA score: 21±3.2. Significant difference between the two groups concerning the clinical outcome was observed after adjusted the data for age. Besides high correlation was noticed between old age and increased rate of poor tissue quality (r=0.88).

Better clinical outcomes are expected in patients associated with good tissue quality, adjusted for age. So the tissue quality is positively correlated with the final functional outcome.

The evaluation of the results obtained after a long term follow up (over 60 months) from patients that were treated arthroscopically for shoulder instability.

In our paper we evaluated 116 patients (108 men and 8 women) with mean age of 24 yo, that were treated surgically by the same surgeon from 1999–2004. Seventy seven (77) of them (66,4%) were into sports activities and during pre op clinical examination 15 patients (12,9%) were diagnosed with joint hypermobility syndrome taking into account the Beighton criteria. Arthroscopic findings showed that 80 of them (68,9%) had some kind of bone loss, either glenoid (7 Large, 23 Medium, 6 Small) or Hill Sachs lesion (28 Large, 30 Medium, 20 Small) and in 8 patients an “inverted pear” glenoid shape was found. Our follow up ranged from 60–117 months (Mean=84) and the recurrence of instability and functional outcome were evaluated post-op using the Rowe Zarins Score.

Recurrent instability presented in 7 patients. Five (5) of them was due to high energy accidents, one was due to non-compliance and one was involuntary. Of these patients 5 presented Hill Sachs lesion, 3 showed glenoid bone loss (2 Large, 1 Small) and in none of them an “inverted pear” glenoid shape was found. All recurrent cases were into some kind of Overhead/Contact sports activity (6 Amateur, 1 Professional). The post op Rowe Zarins Score ranged from 80–100 (Mean=95,53).

The arthroscopic treatment of glenohumeral instability is an excellent method that provides similar or better results when compared to the open surgical treatment and with clear advantages over the latter because of lower morbidity, better cosmetic effect and lower total cost.

The effect of weight-bearing on the height of the patellar using four radiological indices was studied in 25 healthy men using lateral radiographs of the knee in 30° of flexion non-weight-bearing and weight-bearing. The position of the patella was quantified using the Insall-Salvati, the modified Insall-Salvati, the Blackburne-Peel and the Caton indices. The contraction of the quadriceps on weight-bearing resulted in statistically significant proximal displacement of the patella with all four indices studied. The mean Insall-Salvati index was 0.919 (sd 0.063) before and 1.109 (sd 0.042) after weight-bearing (p = 0.001), while the mean modified Insall-Salvati index was 0.734 (sd 0.039) before and 0.896 (sd 0.029) after weight-bearing (p = 0.041). Similarly, the Blackburne-Peel index was 0.691 (sd 0.09) before and 0.807 (sd 0.137) after weight-bearing (p = 0.012). The mean Caton index was 0.861 (sd 0.09) before and 0.976 (sd 0.144) after weight-bearing (p = 0.023).

The effect of quadriceps contraction should be considered in clinical studies where the patellar position indices are reported.

The middle third of quadriceps tendon is an autograft of sufficient size and strength and is stronger than the patellar tendon autograft with the same dimensions. We present the results from the use of a quadriceps autograft for the reconstruction of the chronically ACL deficient knee.

Between March 1999 and March 2000 we treated 36 patients with chronic ACL deficiency using a quadriceps tendon autograft, harvested from the middle third of the tendon with and without a patellar bone block.

The tendinous side of the graft was stabilized using the Mark II and Patella Soffix fixation systems (Surgicraft, UK). In the tibia the graft was passed through a tunnel and in the femur it was passed over the top. In those cases where the graft was harvested with a bone block, his was fixed to the tibia using interference screw fixation. The mean postoperative follow up was 21 months. The results have been evaluated using the IKDC, the Lysholm and the Tegner scales. According to the International Knee Documentation Committee rating system most of the patients had normal or nearly normal ratings. Knee laxity was evaluated using the arthrometers KT-2000 and Rolilmeter. There were no significant complications related to the harvesting site and there was no significant differences between the two groups regarding stability and function. MRI evaluation and second look arthroscopies in 7 patients revealed graft survival

The quadriceps tendon-patellar autograft is a reasonable alternative ACL reconstruction in primary and probably revision ACL reconstruction with minimal donor site morbidity and restoration of knee stability.

The aim of the present study was to compare the amount of blood loss between Gamma nail and DHS operative procedures in treating fractures N.O.F.

Material and Method: thirty patients 81 years of age (average), suffering from N.O.F. fracture were divided in two groups, depending on sex, age, weight and type of fracture, in such way that for every patient operated using one procedure there was a similar one treated with the other one (pairing). The admission and discharge Ht, the blood unites needed for the whole patients hospitalization time were compared.

Statistically T-test, Pearson chi square – Fisher exact test were used.

Results: The average age for the Gamma nail group and DHS group were 82 yrs (sd=11,5) and 81,3 (sd=10,6), the admission Ht 36,9% (sd=4,0) and 36,72% (3,27) and the discharge Ht. was 33,2% (sd=2) and 34,9% (sd=2.9) respectively. For the first group (Gamma nail) 2.3 (sd=1.1) units of blood were used, compared to 2.4 (sd=0.7) for the second one (DHS). There was no statistical difference concerning the age and the population sample, the admission and discharge Ht, and the blood units needed between these two groups.

Conclusion: There is no difference concerning blood loss between Gamma nail and DHS in treating fractures N.O.F.

Purpose of this study is to examine the role of MRI arthrography in chronic cases of shoulder instability. Shoulder arthroscopy was elected as standard record of diagnosis.

Patients & Method: We evaluated 155 shoulder arthroscopies in 153 cases of recurrent shoulder instability from Sept 99 to Feb 03. Each patient suffered at least 2 true dislocations. Pre-op, we performed MRI scan in 82 of them while, 15 other cases were evaluated more invasively with MRI arthrography, with anterior portal infusion technique. Results were analyzed blindly from 2 radiologists with particular experience in MRI musculoskeletal cases and were compared to arthroscopic findings.

Results: Bankart lesion was diagnosed in all cases with MRI arthrography (sensitivity 100%), SLAP lesion had sensitivity 50% and specificity 100% while, rotator cuff pathology was diagnosed in 6 out of 7 cases. There were also 4 false positive cases in rotator cuff pathology. Sensitivity for superior and inferior gleno-humeral ligament was 100% and 94% respectively, without any true negative findings in both of them. Sensitivity and specificity for middle glenohumeral ligament was 89% and 60% respectively. In cases where we recognized loose anterior capsule pathology during arthroscopy, the radiologists were not able to detect these lesions from a functional aspect. Despite the fact, that all Hill Sachs lesions were identified through MRI arthrography it was also possible to be detected functionally.

Conclusions; MRI arthrography is a reliable tool in recurrent shoulder instability while is an invasive method because of the infusion material. Anterior glenohumeral instability is not always a Bankart lesion but gleno-humeral ligaments pathology too that, can easily be detected during arthroscopy which may be the therapeutic solution at the same time.

Aim: Lumbar spinal stenosis is a common disease in spine surgery, especially for older patients. Internal laminoplasty technique is minimal invasive and can offer relieve from symptoms and early recovery to the patient. This method is our choice for surgical treatment in lateral spinal stenosis.

Material and Method: From 1996–2002, 48 patients (28 male-28 female) operated for lumbar spinal stenosis (central or lateral).Eighteen(18) of them in level L3-L4, twenty two(22) in level L4-L5 and eight(8) in level L5-S1 with mane age of 62 years. Their clinical condition was neurogenic claudication, radiculopathies and/or bladder dysfunction. Preoperative examination included X-rays, 3-D X-rays, CT-scan (in combination with myelography in many cases) and MRI.

Results: We used internal laminoplasty without fusion for all cases.

We had no infection or neurological complication. 44patients (91%) mentioned sufficient clinical improvement and pain relief.

Conclusions: Internal laminoplasty technique is a progress in microsurgery, which reduces iatrogenic damage and rehabilitation time, giving excellent results when it is indicated.

Aim: To describe the technique and the mid term results of anterior shoulder instability arthroscopic reconstruction.

Patients-methods: Between March and December 2000 29 patients-28 males with ages ranging between 19–29 years (mean age 23 y.) and 1 female 24 years old-underwent arthroroscopic stabilization of anterior shoulder instability. During the procedure the anterior-inferior part of the labrum was reattached to the glenoid using bioabsorbable and metallic suture anchors. In selected patients in which capsule plication after anchors’ insertion was insufficient additional capsular shrikange or/and rotators’ interval closure was also performed.

Results: Postoperatively patient evaluation took place using Rowe-Zarins scale. According to this score 22 patients (75,9%) had excellent or very good outcome. Three (3) patients (10,35%) were lost during follow up while 1 (3,45%) died. From the remaining 25 patients 2 had recurrence of the instability (6.9%) and in 1 patient (3,45%) a stiff shoulder was noticed and arthroscopically resolved. Finally a disengaged metallic suture anchor was noticed incidentally during routine radiographic examination in one patient (3,45%).The anchor was successfully removed under arthroscopic visualization without compromising the final outcome.

Conclusions: Arthroscopic reconstruction of anterior shoulder instability when precisely performed after correct patient selection is an effective technique achieving results comparable to those of traditional open procedures.

Aim: The description of technique and early results of arthroscopic rotator cuff tears (RCT) reconstruction.

Patients-Methods: Âetween 01/2001 and 02/2003 26 patients, ranging in age from 33–82 (mean age 61,5 y.) – 17 males, 9 females – with RCT underwent arthroscopic reconstruction including debridement, sub-acromial decompression and mobilization of the rotator cuff. The RCT was then repaired with the arm in neutral position using “side to side” suturing technique and rotator cuff anchors when needed. Postoperatively, rehabilitation program included initially passive, active kinisiotherapy while exercises under resistance were finally performed..

Results: All patients were evaluated using ASES and UCLA scores pre-and postoperatively. Pain relief postoperatively was noticed in almost all reconstructed patients. In order to indentify functional improvement range of motion and strength were seperately evaluated. Range of motion just as pain remission was notably improved in almost all patients while strength ameliorate most in patients with complete restoration of rotator cuff tear. The interval between reconstruction and full patients’ recovery ranged between 3 months – pat. < 60 years – to 6–8 months – pat. > 60 years.

Conclusions: Arthroscopic RCT reconstruction although a demanding technique achieves satisfactory early results—mainly regarding pain relief and range of motion improvement- comparable to those of open repair reducing also postoperative morbidity.

Purpose of this report is to present a surgeons group experience in shoulder arthroscopy step by step from a diagnostic status to a therapeutic one, in cases of recurrent instability, impingement syndrome and rotator cuff pathology. There is focus on technique tips, learning curve period, complications and solutions.

We evaluated 250 shoulder arthroscopies from May 99 to Apr.03. 155 cases of them were recurrent instability reconstructions in young patients (16–34 years old, ave.24,3) while the rest of them were rotator cuff pathology patients (22–69 years old ave.44,3). Lateral decubitus position was elected as the standard position in all cases. Patients were operated from a group of two surgeons each time. We analyzed parameters as, EUA, learning curve, technique tips concerning labrum mobilization, anchors and shuttle relay insertion and capsule plication. We describe the intra-op complications and the way out of them. There is also a detection where arthroscopic shoulder instability reconstruction was contraindicated and open technique was preferred.

Our experience in arthroscopic shoulder instability reconstruction and rotator cuff pathology showed that, is a minimally invasive technique. The learning curve period is high, better results can be anticipated when there is a surgical group and when there is a carefully elected sample of patients as it was in our cases.

Aim: Traumatic shoulder dislocation in patients older than 50 years is an unusual injury with specific anatomic lesions and different treatment considerations than these encountered in younger patients. We present our experience in treating such kind of injuries.

Patients-methods: Between January December 2002 9 patients-4 males, 5 females – with ages ranging between 50–72 years (mean age 64 y.), have been treated in our department suffering from first traumatic shoulder dislocation. Rehabilitation program and overall recovery progress was observed in an outpatient basis while postoperative outcome was evaluated using ASES and UCLA rating scores.

Results: In 4 patients rotator cuff tear was found and reconstructed by suturing the lesion. One (1) of these patients, who had a coexisted bony Bankart lesion, presented 1 ½ month postoperative with recurrence of dislocation. Bony Bankart lesion prevented reduction in 2 patients and was reconstructed using open stabilization in one and arthroscopic to the other. HAGL lesion was detected in another patient and treated with open reduction and shoulder stabilization. Finally 2 patients with shoulder dislocation and coexisted greater tuberosity fracture were treated with closed reduction.

Conclusions: Ttraumatic shoulder dislocation in patients older than 50 years consists a distinct entity which if inadequately treated leaves the shoulder with severe functional impairment. Recurrent shoulder dislocation is an unusual complication in such patients but on the other hand rotator cuff tears and glenoid bony lesions are frequently encountered necessitating treatment. Postoperative patients should be examined in small intervals with a high degree of suspicion for the above mentioned coexisted lesions.
