Pisotriquetral arthrodesis as an alternative to excision for pisotriquetral instability in high-demand patients: a case report in a gymnast.

UNLABELLED: A gymanast developed ulnar wrist pain caused by pisotriquetral instability. Pisotriquetral arthrodesis resulted in pain relief and sufficient functional return to allow her to return to gymnastics. Pisotriquetral arthrodesis is a feasible alternative to pisiform excision worth consideration in high-demand patients with symptomatic pisotriquetral instability or arthrosis. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level V.

Gymnastic wrist injuries.

Wrist injuries in the gymnast are due to the transformation of the upper extremity into a weight bearing entity. Both acute and chronic disorders occur and are difficult to manage in these athletes because of the intensity of training and competition. Treatment is dependent on the injury as well as the expectations of the patient, coach, and family--a situation that at times may alter the usual management program.

Sphincter (ring muscle) gymnastics for spinal cord injured and spinal cord transected patients.

Sphincter gymnastics seem to be able to recruit central pattern generators--networks of neurons that generate motor patterns--through peripheral rhythmic stimuli and to activate them without supraspinal signals. This physical therapy method is thus suitable for treating spinal cord injured and spinal cord transected patients, for it can reach below the injured segment and feed signals into the central nervous system, thus activating vital organs. This article presents some observations and discusses a possible mechanism.

Energy cost and energy sources of ball routine in rhythmic gymnasts.

The energy cost and the different energy sources of competitive rhythmic ball-routines were assessed in nine young elite rhythmic gymnasts (13-16 years of age). The overall energy requirement of ball exercise (VO2eq) was obtained by adding the amount of VO2 during exercise above resting (VO2ex) to the VO2 up to the fast component of recovery (VO2al) and to the energy equivalent of peak blood lactate accumulation (VO2la-) of recovery. The lactate (La) curve up to 25 minutes of recovery always showed La peaks at 3 min after exercise (4.0 +/- 0.4 mmol/l) and values still above rest at 25 min (2.3 +/- 0.5 mmol/l). Although ball routines were short in duration (90 s), the metabolic power requirement was 1.1 times higher than the subject's VO2max. The energy cost (VO2eq) amounted to 81 +/- 5 ml x kg(-1). Higher fractions of VO2eq were VO2ex 49% and VO2al 42%, while the remaining 9% was due to VO2la-. The aerobic source resulted in the most utilized system due to the subjects' high VO2max (52.7 ml x kg(-1) x min(-1)) and anaerobic threshold (LT = 84.4%). The HR and the peak lactate values of ball routine were similar to the values recorded at LT step during treadmill test. Although the HR and VO2 values were significantly correlated (during pre-exercise, exercise, and fast recovery), the exercise intensity derived from HR Kanvonen method during ball routine did not correspond to the % of VO2max.

Effects of the removal of vision on body sway during different postures in elite gymnasts.

The aim of this study was to analyse the effects of the removal of vision on postural performance and postural control in function of the difficulty and specificity of the posture. Twelve elite gymnasts were instructed to be as stable as possible with eyes open and eyes closed in three postures: bipedal, unipedal, and handstand ranked from the less difficult and less specific to the more difficult and more specific. The ratios eyes closed on eyes open, computed on CP surface and CP mean velocity, which respectively represents postural performance and postural control, were similar in the bipedal and handstand postures. They were highly increased in the unipedal one. The effect of the removal of vision and so the role of vision on body sway was not directly linked to the difficulty or specificity of the posture; other tasks' characteristics like the segments configuration also played a role.

Sterno-manubrial dislocation in a 9-year-old gymnast.

Dislocations of sternal segments in children are extremely rare lesions; only seven sterno-manubrial dislocations have been reported in the literature. We present a case of posterior sterno-manubrial dislocation in a 9-year old gymnast exercising on parallel bars. We preferred performing an open reduction and plate stabilization using an angular stable implant, because of pain and respiratory distress. This technique of stabilization has not been described in the literature before and present the advantage of combining a high stability with a reduced risk of iatrogenic retrosternal injury. The plate stabilization led to an immediate amelioration of symptoms. The plates could be removed 4 months after initial treatment. The boy rapidly regained his sporting capabilities.

Techniques used in high-scoring and low-scoring 'Roche' vaults performed by elite male gymnasts.

The 16 highest-scored Roche vaults (G1) performed during the 2000 Olympic Games were compared with those receiving the 16 lowest-scores (G2). A 16-mm motion picture camera operating at 100 Hz recorded the vaults during the competition. The results of t tests (p < .05) indicated G1, compared to G2, had (a) shorter time of board support, greater normalised average upward vertical force and backward horizontal force exerted by the board, greater change in the vertical velocity while on the board, and greater vertical velocity at board take-off, (b) comparable linear and angular motions in pre-flight, (c) smaller backward horizontal impulse exerted by the horse, smaller loss of the horizontal velocity while on the horse, and greater horizontal and vertical velocities at horse take-off, (d) greater height and larger horizontal distance of post-flight, (e) higher body mass centre at knee release, and (f) higher mass centre, greater normalised moment of inertia, and smaller vertical velocity at mat touchdown. Therefore, gymnasts and coaches should focus on sprinting the approach; blocking and pushing-off the take-off board rapidly and vigorously; departing the board with a large vertical velocity; exerting large downward vertical force and small forward horizontal force from the hand-stand position while on the horse; departing the horse with large horizontal and vertical velocities; and completing the majority of the double salto forward near the peak of trajectory and releasing the knees above the top of the horse to prepare for a controlled landing.

Chronic tuberculous rheumatism (Poncet's disease) in a gymnast.

Chronic arthritis, whether primary or reactive, is an unusual manifestation of long standing tuberculosis. We described the case of a 16-year-old gymnast with tuberculous rheumatism (Poncet's disease) secondary to Pott's disease of the dorsal spine. The possible pathogenetic mechanisms are discussed.

Spinal sagittal configuration and mobility related to low-back pain in the female gymnast.

The purpose of this study was to correlate low-back complaints in 64 female gymnasts (mean age, 12 years) to spinal sagittal configuration and mobility as measured by two noninvasive methods. Measurements by Debrunner's kyphometer and Myrin's inclinometer were highly correlated. Average thoracic kyphosis was 32 degrees, lumbar lordosis 35 degrees. The mean range of sagittal motion was 57 degrees in the thoracic spine and 113 degrees in the lumbar spine. On average, 1 degree of the total sagittal lumbar mobility was lost for every 1 degree of increased lordosis. Low-back pain (LBP) was reported by 20% of the girls, and these girls had a significantly larger lordosis (41 degrees) than girls with no history of LBP (35 degrees).

Wrist pain and distal growth plate closure of the radius in gymnasts.

Three cases in which wrist pain developed in skeletally immature competitive gymnasts are presented. In all three cases there is radiographic evidence of premature growth plate closure, resulting in shortening of the radius and alterations in the normal distal radioulnar articulation. Repetitive compressive loading of the distal growth plate of the radius is proposed as a potential etiology of this condition. Treatment goals, including an example of successful ulnar shortening, are reviewed. The authors suggest activity limitation with the onset of symptoms, in order to avoid the permanent structural changes observed in our patients.

Derangement of the articular surfaces of the elbow in young gymnasts.

We report the long-term follow-up of lesions of the articular surface of the elbow joint in a group of 12 young gymnasts. There was a high incidence of osteochondritic lesions, intraarticular loose bodies, and precocious signs of joint aging. The prognosis of elbow joint articular surface lesions in these athletes is not good, with only one athlete being able to continue high-level activity at maturity.

Stress inoculation training: a case study in gymnastics.

A young female gymnast of regional squad potential had ceased to make progress when she resumed training after a series of injuries and was given stress inoculation training to help her to regain her form. Preliminary interviews revealed that she had developed a number of negative self-statements and images which, it was hypothesised, may have been contributing towards her lack of progress. In order to replace these with positive self-statements and images a treatment programme of eight training sessions was implemented. Recorded interviews and subsequent comparison of comments made by the subject before and after the intervention programme, indicated that the training had been successful. This was endorsed by the coaches who reported an improved attitude to training and rapid progress in skill learning.

Stress fracture of the clavicle in a young female gymnast.

Stress fractures of the clavicle are rare. This is the report of one such fracture in a 10 year old female gymnast, who presented with a six week history of medial clavicular pain. Radiographs and a computed tomography scan showed an undisplaced fracture through the medial third of the clavicle extending inferiorly to the rhomboid fossa in the inferior aspect of the clavicle. Pathological fracture was excluded by magnetic resonance imaging. The patient was treated conservatively and was able to return to full training eight weeks later.
