Groin pain in athletes

Sports hernia: diagnosis and therapeutic approach

Groin pain is a common entity in athletes involved in soccer, ice hockey, Australian Rules football, skiing, running, and hurdling. An increasingly recognized cause of groin pain in these athletes is a sports hernia, an occult hernia caused by weakness or tear of the posterior inguinal wall, without a clinically recognizable hernia, that leads to a condition of chronic groin pain. The patient typically presents with an insidious onset of activity-related, unilateral, deep groin pain that abates with rest. Although the physical examination reveals no detectable inguinal hernia, a tender, dilated superficial inguinal ring and tenderness of the posterior wall of the inguinal canal are found. The role of imaging studies in this condition is unclear; most imaging studies will be normal. Unlike most other types of groin pain, sports hernias rarely improve with nonsurgical measures; thus, open or laparoscopic herniorrhaphy should be considered.

Successful endoscopic treatment of chronic groin pain in athletes

BACKGROUND

Chronic groin pain, especially in professional sportsmen, is a difficult clinical problem.

METHODS

From January 1999 to August 2005, 55 professional and semiprofessional sportsmen (53 males; mean age, 25 +/- 4.5 years; range, 17-36 years) with undiagnosed chronic groin pain were followed prospectively. All the patients underwent an endoscopic total extraperitoneal (TEP) mesh placement.

RESULTS

Incipient hernia was diagnosed in the study athletes: 15 on the right side (27%), 12 on the left side (22%), and 9 bilaterally (16%). In 20 patients (36%), an inguinal hernia was found: 3 direct inguinal hernias (5%) and 17 indirect hernias (31%). All the athletes returned to their normal sports level within 3 months after the operation.

CONCLUSIONS

A TEP repair must be proposed to patients with prolonged groin pain unresponsive to conservative treatment. If no clear pathology is identified, reinforcement of the wall using a mesh offers good clinical results for athletes with idiopathic groin pain.

Abnormalities in and Around the Hip: MR Imaging Versus Sonography

Sonography and MR imaging should be considered complementary rather than competing modalities. They demonstrate similar abnormalities of the soft tissues, but MR imaging is able to demonstrate intraosseous and articular abnormalities and offers a better anatomic overview because of its larger field of view, whereas sonography offers dynamic evaluation and can provide real-time guidance for percutaneous procedures. Both of these modalities have roles in the imaging evaluation of injuries in and around the hip.

Lichtenstein inguinal hernioplasty: sutures versus glue

INTRODUCTION

This was a prospective, randomised study undertaken from January 2001 to July 2003 firstly to assess the possibility of using glues to fix meshes, secondly to verify whether or not this leads to a higher hernia recurrence rate, and thirdly to assess post-operative pain.

METHODS

This study covered a total of 55 patients with bilateral hernias who presented similar characteristics on both sides and on whom fixation of the mesh was undertaken differently, depending on the side. On the right side polypropylene sutures were used (prolene 2/0), while on the left, attachment was done using glue (Tissucol).

RESULTS AND CONCLUSIONS

Results were similar in both inguinal regions, although there was less post-operative pain and less inflammatory reaction on the left side. There was no hernia recurrence in the follow-up at the end of 1 year.

Training Room Management of Medical Conditions: Sports Gastroenterology

Gastrointestinal (GI) illnesses are common in athletes. Various causes include adverse physiologic adaptations of the gut during exercise; excess ingestion of carbohydrate drinks, alcohol, and anti-inflammatory medications; emotional stressors; exposure to pathogens in closed environments and during travel; trauma; and abdominal wall pressure overload. Unfortunately, evidence-based management of GI illnesses in athletes is limited because most studies have compared various GI illnesses between different sports, rather than comparing athletes to nonathletes. This article reviews the evidence that is available specifically relating to etiology, pathophysiology, clinical presentation, relevant differential diagnoses, acute management, and recommendations for specialist consultation of various GI illnesses in the training-room setting.

Efficacy of dextrose prolotherapy in elite male kicking-sport athletes with chronic groin pain

OBJECTIVE

To determine the efficacy of simple dextrose prolotherapy in elite kicking-sport athletes with chronic groin pain from osteitis pubis and/or adductor tendinopathy.

DESIGN

Consecutive case series.

SETTING

Orthopedic and trauma institute in Argentina.

PARTICIPANTS

Twenty-two rugby and 2 soccer players with chronic groin pain that prevented full sports participation and who were nonresponsive both to therapy and to a graded reintroduction into sports activity.

INTERVENTION

Monthly injection of 12.5% dextrose and 0.5% lidocaine into the thigh adductor origins, suprapubic abdominal insertions, and symphysis pubis, depending on palpation tenderness. Injections were given until complete resolution of pain or lack of improvement for 2 consecutive treatments.

MAIN OUTCOME MEASURES

Visual analog scale (VAS) for pain with sports and the Nirschl Pain Phase Scale (NPPS), a measure of functional impairment from pain.

RESULTS

The final data collection point was 6 to 32 months after treatment (mean, 17 mo). A mean of 2.8 treatments were given. The mean reduction in pain during sports, as measured by the VAS, improved from 6.3+/-1.4 to 1.0+/-2.4 ( P <.001), and the mean reduction in NPPS score improved from 5.3+/-0.7 to 0.8+/-1.9 ( P <.001). Twenty of 24 patients had no pain and 22 of 24 were unrestricted with sports at final data collection.

CONCLUSIONS

Dextrose prolotherapy showed marked efficacy for chronic groin pain in this group of elite rugby and soccer athletes.

Secondary cleft sign as a marker of injury in athletes with groin pain: MR image appearance and interpretation

PURPOSE

To determine whether the secondary cleft sign demonstrated in the symphysis pubis at magnetic resonance (MR) imaging is a marker of injury in athletes presenting with groin pain.

MATERIALS AND METHODS

Ethics review board approval was not required for studies involving retrospective image or case record review; informed consent for review was not required. Eighteen male athletes (mean age, 24 years; age range, 19-32 years) were included for study. All patients underwent radiography and MR imaging (coronal fast spin-echo T1-weighted, transverse fast spin-echo T2-weighted, and coronal turbo short inversion time inversion-recovery [STIR] imaging) of the pelvis. Subsequent image-guided nonionic contrast material injection was followed by a 0.5% bupivacaine hydrochloride (1 mL) and methyprednisolone acetate (20 mg) injection into the central cleft of the symphysis pubis. Comparison was made between imaging findings at symphyseal cleft injection and appearances at preprocedure MR imaging, with specific reference to the presence of a secondary cleft. The sensitivity and specificity of MR imaging in demonstrating the secondary cleft sign were compared with those of the reference standard, imaging at symphyseal cleft injection. MR images from a reference group of 70 asymptomatic athletes who underwent STIR imaging of the pelvis were analyzed for evidence of a secondary cleft.

RESULTS

Osteitis pubis was diagnosed in six patients on the basis of radiography and/or MR imaging. A secondary cleft was identified in 12 of 18 patients at MR imaging, was best visualized at coronal STIR imaging, and was confirmed in each patient during contrast material injection into the central physiologic symphyseal cleft. In no patient was a secondary cleft identified at symphyseal cleft injection and not identified at MR imaging (sensitivity and specificity, 100%). In each patient, the side of the secondary cleft corresponded to the side of symptoms that responded to local anesthetic and steroid injection. Four of the six patients with osteitis pubis had evidence of a secondary cleft. In one patient, a secondary cleft was not identified at MR imaging or symphyseal cleft injection, but adductor avulsion was identified at MR imaging. No evidence of a secondary cleft sign at MR imaging was identified in the reference group.

CONCLUSION

The secondary cleft sign demonstrated at MR imaging is a marker of groin injury in athletes presenting with groin pain.

An Overview of Hip Injuries in Running

Running has steadily gained in worldwide popularity and is the primary exercise modality for many individuals of all ages. Its low cost, versatility, convenience and related health benefits appeal to men and women of broad cultural, ethnic and economic backgrounds. With more children and adults participating in recreational and competitive running, the incidence of injuries has steadily increased. Most running-related injuries affecting the lower extremities are due to preventable training errors, and some may necessitate medical evaluation or a significant reduction in training. Hip injuries in runners are due to interactions of intrinsic and extrinsic factors that adversely affect the complex regional anatomy. Acute or chronic hip pain presents a diagnostic and therapeutic challenge because the vague, nonspecific symptoms and signs may originate from local, regional or distant foci. Muscle strains and tendonitis are the most common aetiologies of hip pain and typically result from sudden acceleration/deceleration manoeuvres, direction changes or eccentric contractions. Apophysitis and avulsion fractures may affect younger runners and produce localised pain at muscle attachment sites. Iliotibial band syndrome is a common cause of lateral hip and knee symptoms characterised by sharp or burning pain that is exacerbated by activity. Bursitis, due to repetitive activity or acute trauma, may affect the trochanteric, ischial or iliopectineal bursae. Hip osteoarthritis may also produce persistent pain that worsens with running. Stress fractures are potentially serious conditions that affect women more frequently than men. Snapping hip syndrome is a benign condition that results from tight connective tissues' passing repeatedly over the greater trochanter, anterior hip capsule, lesser trochanter, femoral head or iliopectineal eminence. Acetabular labral tears, sports hernias and nerve entrapment syndromes are also potential causes of persistent hip pain in runners. Treatment of hip pain in running should focus not only on addressing the symptoms but also identifying the underlying conditions that precipitated the injury. Injury prevention and comprehensive rehabilitation are essential, since prior hip injuries increase the risk of subsequent ones. Coaches, trainers and medical personal who care for runners should advocate running regimens, surfaces, shoes, technique and individualised conditioning programmes that minimise the risk of initial or recurrent hip injuries.
