Aims: Healing of the rotator cuff after surgical repair continues to be one of the most challenging areas of shoulder surgery. Autologous Platelet Derived Grow Factors (PDGF) have been shown to positively affect the tissue healing, but their effect have not been studied in relation to tendon healing. The purpose of this study is to evaluate if the use of PDGF in rotator cuff surgery could lead to a better and faster healing of the repair.

Materials e Methods: We treated two groups (A,B) of 14 shoulders in 14 patients (mean age 66 and 63.4) with a full thickness rotator cuff tear. The group A and B were treated with a full arthroscopic repair of the cuff. In the group A, at the end of the procedure, the PDGF have been injected at the level of the lesion, between the tendon and the bone and over the tendon repair without irrigation and after the removal of all the cannulas. The group B, repaired in the same fashion, without PDGF, has been used as control.

In the group A the patients had an accelerated postop. rehabilitation. The group B received a standard rehabilitation protocol. Each group has been evaluated prospectively with VAS, UCLA and Constant scores pre-op and during follow-up.

Results: Both group showed an increase of the scores, compared to the pre-op. value (tab.1).

The VAS score of group A (PDGF) was pre-op. 5.6 and at 1 year 1.4. The VAS score of group B (no PDGF) was pre-op. 5.2 and at 1 year 1.4. The UCLA score of group A was pre-op. 16 and at 1 year 33.8. The UCLA score of group B was pre-op. 16.7 and at 1 year 32.9. The Constant score of group A was pre-op. 53 and at 1 year 90.7. The Constant score of group B was pre-op. 54.2 and at 1 year 90.1.

The complete statistical analysis of the data showed no significant differences in the results of the two groups (p< 0,01), with every kind of scores, VAS, UCLA and Constant, at the final follow-up of 1 year.

Conclusions: Our data suggest that the use of PDGF, compared to a standard repair, does not affect the quality of the rotator cuff repair at 1 year. Moreover the study suggest that the use of PDGF allows an accelerated rehabilitation program with ten days of immobilization compared to four weeks as usually prescribed. Further studies should clarify the real effect of PDGF about the acceleration of the first phase of the cuff healing.

Aims: Traditionally in surgery, and this is especially true in orthopaedic foot surgery, is not paid much attention to patient’s emotions, not considering how specific personality traits could affect pre and post surgical management. Following the guidelines of WHO about the treatment of pain and in order to optimize the clinical management of patients who complain of painful foot disorders such as hallux valgus, we studied the relation between level of anxiety, perception of pain and memory pain before and after the surgical procedure.

Methods: In the period 2000 and 2004 we studied 88 patients who were treated with distal metatarsal osteotomy for correction of hallux valgus. In order to evaluate anxiety trait level we selected one of the most frequently employed tests in clinical medicine (S.T.A.I. Y2). To quantify the amount of pain, due to such pathology in the pre and post surgical period, FFI test (visual analogous) and a questionnaire on pain memory, were employed. Pain was studied longitudinally, in the following steps: presurgery, immediately postsurgery, daily in the first four days, and at one and two weeks interval after the procedure. The use of analgesic drugs in the first two weeks was recorded. Two years later the same patient were recalled in order to collect data related to the clinical outcome and pain memory persistence.

Results: A subgroup of 33 patients showed an high anxiety trait level (score > 43), the remaining 50 patients had a score in the normal range.

The statistical analysis of the data shows a direct correlation between anxiety level and pain perception in the pre surgical period. Furthermore, patients with higher level of anxiety showed an increased use of analgesic drugs in the post surgical period (the higher dosage prescribed on demand). The unpleasant memory persistence is however mitigated in the same group, possibly due to much drug assumption.

Conclusions: A correct management of patients with painful diseases candidated to surgical procedures should include a comprehensive psychological evaluation in order to identify their emotional state. Especially in clinical situations requiring bilateral surgical approaches is mandatory to avoid that pain could become a traumatic experience.
