Introduction

Distal radius fractures (DRF) are a common injury in the A&E departments, being a major cause of disability of the upper extremity. The aim of this prospective study is to assess the possible association between objective physical variables such as wrist range of movement (ROM), radiological parameters, and upper extremity disability (measured by the DASH questionnaire), after conservative treatment of DRF.

Introduction: Our aim is to analyse the results for the treatment of metatarsalgia comparing, in a retrospective way, Opened surgery (standard Weil osteotomy, group O) and Percutaneous surgery (osteotomies of the metatarsal neck with no internal fixation, group P).

Material and method: We review 30 cases in each group according to demographic data, surgery procedure, complications, time to healing and metatarsal curve. An interview with every patient was performed in order to obtain the AOFAS scale results, time to wear comfort shoes, return to daily activities, analgesia needed, visual analogic scale and global satisfaction.

Results: Group O: 29 women, 1 man. Mean age of 61 years. Mean number of metatarsal osteotomies per patient 2,21. 27 cases associated to hallux valgus surgery.

Group P: 25 women, 5 men. Mean age of 51,5 years. Mean number of metatarsal osteotomies per patient 2,56. 23 cases associated to hallux valgus surgery.

Groups O/P: time to bone healing 4,21/17,5 weeks; AOFAS scale 80,56/88,32 points; VAS 3,0/2,04 points; metatarsal curve in milimeters −0,75/−4,67/−6,67/−12,2 vs +0,72/−5.72/−5,52/−11,52; time to wear comfort shoes 18/11 weeks; return to daily activities 12,4/10,5 weeks; analgesia needed for 9/5 weeks. Global satisfaction was: group O 44% excellent, 24% good, 20% fair and 12% bad; group P 54% excellent, 25% good, 7% fair and 14% bad. Complications: 44.8% in group O (mainly minor problems of wound) and 23,3% in group P (mainly non-unions).

Conclusions: We would like to remark the differences with statistical significance: mean age is lower in group P, time to bone healing is longer in group P but time to wear comfort shoes is shorter in these patients.

There are no statistical differences for metatarsal curve. According to AOFAS scale there are no differences except for the alineation items (better in group O). No differences neither for global satisfaction of the patients nor for visual analogic scale. Complications are predictable for each technique: skin problems in group O and union problems in group P.

We conclude that both procedures are acceptable in the treatment of metatarsalgia with similar objective and subjective results.

Introduction: Activated platelets release various growth factors, some ot which are recognize to improve nerve regeneration. The present study evaluated the effect of platelet-rich-plasma (PRP) in end to end neurorraphy.

Material and method: A total of 38 Spragle-Dawley rats were used. The PRP was obteined from each rat and applicated to the same rat. The left hind limb were used as experimental, with the right as control. The animals were treated in two grups. In both groups the sciatic nerve was dissected from the sciatic notch to the bifurcation. The nerve was transected an repaired with epineural suture (ethilon 9–0). Group A (n=12): suture without PRP. Group B (n=15) suture with PRP. The rats were anestherized and electromyographic studie was performed after the following, 120,5 days for group A and 125,86 for group B. Prior to sacrifice muscular and nerve tissue harvesting was performed.

The amplitude was expressed as the amplitude at the experimental sde divided by the amplitude at the contralateral, untreated side, multiplied by 100%. Recording was done in gastrocnemius and tibialis anterior muscle.

Results: The stimulation was performed in supramaximal form on both groups: Group A: (without PRP)

The mean of intensity was 1.49 mA and the mean of threshold was 0,56 mA

No stadistical difference on both groups was found.

Histological studies were performed and results are no available at the moment of send this abstract

Conclusions:

No evidence has been found that the use of PRP has a beneficial effect on peripheral nerve regeneration

Introduction: Osteoarthritis of the thumb basal joint is a very common and disabling condition that frequently affects middle-aged women, sometimes bilaterally. The purpose of this work is to present the methodology of the preoperative and postoperative assessment carried out in 52 patients who underwent a trapeziometacarpal joint replacement procedure (Roseland prosthesis).

Material and Methods: Total joint arthoplasty of the trapeziometacarpal joint was performed on 52 thumbs in 44 patients (15 dominants hands) to treat osteoarthritis (Eaton-Littler stages II and III) between 1995 and 2007. 18 patients were missed for follow-up purposes. Average age of 59,4 years. The Roseland trapeziometacarpal joint prosthesis was used in this study. We analyzed the ROM for abduction-adduction, flexo-extension of the trapeziometacarpal joint and the opposition of the thumb by the modified Kapandji test. We also measured radiographic distance of the TMC space in preoperative radiographies and compared it with the postoperative ones. Finally, strength was quantified for the lateral, tip-to-tip, and tridigital pinch in the treated hands. Pain was measured with VAS and the DASH questionnaire was completed by all the patients. The average follow-up period was of 5,3 years (range, 1,1–12,1 years).

Results: At the final follow-up visit we obtained the following Results: for thumb abduction average 66°, thumb opposition to the base of the smaller finger was present in 58%, and thumb flexo-extension average 59°. The average tip-to-tip pinch strength was 2,7, for the lateral pinch 3,6 and for the tridigital pinch was 3,7. We observed that in 36% of the radiographies the TMC space was the same pre and postoperative. Average VAS and DASH scores were of 1,6 and 26,3 respectively. Five patients (10%) needed a revision surgery (2 for infection and 3 for aseptic loosening of the prosthesis)

Conclusions: Most of the protocols evaluating surgical outcomes on the trapeziometarcarpal joint don’t allow a functional analysis of ROM and strength of this joint. That’s why we developed the idea of designing a new methodology, that we currently use in our centre, to analyze the functional outcome of the surgery on the trapeziometacarpal joint. We specially recommend the measurement of the tridigital pinch strength, as is the most representative feature of the hand function.
