Introduction Apophyseal avulsion fractures of the pelvis are common among teenage football player. Usually, they are the result of a sudden forceful concentric or eccentric contraction of the muscle attached to the apophysis. Indeed, before ossification, the apophyseal growth cartilage is the weakest point in the musculotendinous unit, making the apophysis vulnerable to injure. Athletes most commonly affected are soccer players when they tackle or shot powerful at goal and gymnasts during floor exercises which imposed sudden and excessive lengthening. Management of these fractures remains unclear. There are no guidelines between conservative and surgical approach even if most publications recommend a surgery if the diastasis exceeds 2cm and a conservative approach on the other hand. Case report A sixteen-year-old high-level player presented at the consultation with right ischial pain. Three months earlier, while he was sprinting, he had felt acute pain opposite the ischial tuberosity which compelled him to stop the training. He had already consulted another physician, who prescribed an X-ray which revealed an avulsion fracture of the ischial tuberosity with a maximal diastasis of 1.9 cm (Fig 1.a.). According to most publications (1,3), surgery is advisable from 2 cm of diastasis. 1.9 cm was within the range between a surgical and a conservative approach, and the conservative one was applied. An isokinetic assessment was planned. It highlighted hamstring strength imbalances with bilateral difference of 31% in concentric strength and 28% in eccentric strength in comparison with the healthy side. The mixed ratio of the hamstrings in eccentric mode at 30°/s to quadriceps in concentric mode at 240°/s was decreased to 0.8, while the lower limit in our clinical practice corresponded to 0.9. The patient was not allowed to resume competition and a rehabilitation by specific and progressive strengthening in both modes of contraction was initiated; in particular the eccentric training was initially submaximal and progressively intensified. Six weeks later, isokinetic assessment was repeated and showed significant improvement of right hamstring strength, particularly for eccentric contraction. The greatest improvement was the mixed Hecc/Qconc ratio wich had increased from 0.8 to 1.44. In regard to radiology, we observed no change since the previous X-Ray (Fig 1.b.). Intensified training on the field was allowed in order to resume competition. Less than one year after the injury, the patient restarted competition successfully with performance levels which were almost the same as before the injury. Discussion Many publications have discussed the surgical versus the conservative approach to treating ischiatic avulsion. Most of the published literature advocate the relevance of surgery when the diastasis exceeds 2 cm because widely displaced fractures may lead to chronic symptomatology if the treatment remains conservative. Different criteria, such as pain relief, ability to perform in sport, gross strength, activity score, X-Rays, are used by authors to demonstrate the recovery after treatment. No study accurately measured the hamstring strength before and after treatment. However, strength imbalance, especially as regards the H/Q mixed ratio, significantly increases the risk of sustaining hamstring injury in soccer player (2). For our patient, the rehabilitation enabled him to re-establish hamstring strength in six weeks with substantial improvement of eccentric assessment. The mixed Hecc/Qconc ratio increased from 0.8 to 1.44. This improvement significantly decreased the risk of recurrence of hamstring injury. Regarding X-Ray imagery, there was no evidence of healing. We advocate that radiological assessment should not be the main recovery criterion and that specific strengthening should be started even when avulsion persists on the X-Ray. Furthermore, hamstring strength should be measured accurately and objectively, e.g. by isokinetism, to be one of the main return to play criterion in association with clinical data. [less ▲]

Background: Upper patellar tendinopathies remain often chronic and rebel to a thorough conservative treatment. Moreover, the option of a surgical treatment could be disappointing. New treatments are being developed. Injection of PRP is one of these. Platelets contain lot of growth factors which would have the potentiality to enhance the healing process of tendons. Even if in vitro and animal experiments have demonstrated this stimulation of tendon healing process1, clinical series are subject to controversy2. Methods: Twenty patients with chronic upper patellar tendinopathy were enrolled. Assessments [VAS, clinical examination with an algometer, algofunctional scores (IKDC and VISA-P), functional assessments (isokinetic and Optojump) and imagery (ultrasounds and MRI)]were made before infiltration of PRP, and 6 weeks and 3 months after. The PRP was obtained by an apheresis system (COM.TEC, Fresenius). Six millilitres of PRP were injected without local anaesthetic. One week after infiltration, patients started a 6-week standardised sub-maximal eccentric reeducation. Results: We observed a very significant improvement of the algofunctional status as soon as 6 weeks after the infiltration of PRP, and continued to a lesser extent up to 3 months. During functional evaluation, pain decreased as well, but without significant improvement of performances. No significant improvements in the imagery were observed. Interestingly, patients who had a VAS equal or below 1 after 3 months post-infiltration were younger (24.7 vs 32.2 y.o.). Moreover, these younger patients had a significant increase of the IKDC score (p=0.003), a significant improvement of pain during isokinetic evaluations (p<0.05), and during Optojump assessments (p=0.01). Seventy-five percent of subjects were able to return to sport, even if only half of these patients recovered the same level than before the tendinopathy. Discussion / Conclusions: This study demonstrates that a local infiltration of PRP associated with a submaximal eccentric protocol is efficient to improve symptoms of chronic upper patellar tendinopathies, non-responsive to classical conservative treatments. However, up to now, there is no consensus on the method to prepare the PRP. Indeed, each technique could provide a very different PRP (variations in the platelet concentrations and of the amount of red and white cells). [less ▲]

Compartment syndrome is defined as an increased intracompartmental pressure within inelastic fascia which surround muscular compartments. That pathology can be either acute or chronic. The acute situation is generally a medical emergency. Unless a fasciotomy is rapidly performed, increasing pressure may completely cut off blood flow and cause necrosis of the affected limb. The chronic compartment syndrome, more frequent, is characterized by exercise-induced pain and swelling that is relieved by rest. It results from an excessive intra-muscular pressure increase. The anterior compartment of the leg is most commonly involved. To accurately diagnose the compartment syndrome, physicians perform measurements of compartment pressure. By means of miniature digital instruments, exercise and rest intramuscular pressure are recorded. If pressures reach the critical threshold (30 mm Hg) and remain high five minutes after exercise, compartment syndrome is present. Treatment is nearly exclusively surgical. It consists in an fasciotomy allowing a complete recovery and a return to sport activities. [less ▲]

The purpose of this study was to determine the effectiveness of eccentric training models in treating various types of tendinitis and evaluate protection from re-injury when returning to causal activities, Isokinetic eccentric training was administered to 34 patients with chronic tendinitis (9 Achilles, 10 patellar and 15 epicondyllar) with a long duration of symptoms and failure of conventional treatment. Following training which consisted of 20 to 30 sessions of progressive increase of load and speed parameters, a significant reduction of pain indicated by the visual analog scale (average initial value > 6.5, final score less than or equal to 2.5). Seventy four percent of the patients were completely relieved or presented marked decrease in symptoms when returning to sport and occupational activities. and only 12% reported no change in their functional state. At the end of treatment. isokinetic assessment revealed no significant concentric or eccentric peak torque asymmetries between involved and non-involved sides. In comparison with pretreatment ultrasound observations which showed systematic hypoechoic lesions and thickness, 14/34 patients recovered homogeneous tendon structure and normalization of the diameter and 15 presented improvement in echostructure. Our treatment model proposing isokinetic eccentric exercises presents a very satisfactory short-term effect on three different localizations of chronic tendinitis. [less ▲]
