RESUMEN

BACKGROUND: Controversies remain regarding the diagnosis, imaging, and treatment of acute adductor injuries in athletes. PURPOSE: To investigate the diagnostic imaging, treatment, and prevention of acute adductor injuries based on the most recent and relevant scientific evidence. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: The PubMed and Web of Science databases were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify articles studying acute adductor injury in athletes. Inclusion criteria were original publication on acute adductor injury in amateur or professional athletes, level 1 to 4 evidence, mean patient age >15 years, and results presented as return-to-sport, pain, or functional outcomes. Quality assessment was performed with the CONSORT (Consolidated Standards of Reporting Trials) statement or the methodological index for non-randomized studies criteria. Articles were grouped as imaging, treatment, prevention focused, or mixed. RESULTS: A total of 30 studies published between 2001 and 2021 were selected, involving 594 male patients with a mean age 26.2 years (range, 16-68 years). The most frequent sports were soccer (62%), basketball (14%), futsal (6%), American football (3%), and ice hockey and handball (2%). Risk factors for acute adductor injury were previous acute groin injury, adductor weakness compared with the uninjured side, any injury in the previous season, and reduced rotational hip range of motion. The frequency of complete adductor muscle tears on magnetic resonance imaging was 21% to 25%. For complete adductor tears, the average time to return to play was 8.9 weeks in patients treated nonoperatively and 14.2 weeks for patients treated surgically. Greater stump retraction was observed in individuals treated surgically. Partial acute adductor tears were treated nonoperatively with physical therapy in all studies in the present systematic review. The average time to return to play was 1 to 6.9 weeks depending on the injury grade. The efficacy of adductor strengthening on preventing acute adductor tears has controversial results in the literature. CONCLUSION: Athletes with partial adductor injuries returned to play 1 to 7 weeks after injury with physical therapy treatment. Nonoperative or surgical treatment is an acceptable option for complete adductor longus tendon tear.

RESUMEN

BACKGROUND: Controversies remain regarding the surgical treatment of inguinal-, pubic-, and adductor-related chronic groin pain (CGP) in athletes. PURPOSE: To investigate the outcomes of surgery for CGP in athletes based on surgical technique and anatomic area addressed. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: The PubMed and Embase databases were searched for articles reporting surgical treatment of inguinal-, pubic-, or adductor-related CGP in athletes. Inclusion criteria were level 1 to 4 evidence, mean patient age >15 years, and results presented as return-to-sport, pain, or functional outcomes. Quality assessment was performed with the CONSORT (Consolidated Standards of Reporting Trials) statement or MINORS (Methodological Index for Non-randomized Studies) criteria. Techniques were grouped as inguinal, adductor origin, pubic symphysis, combined inguinal and adductor, combined pubic symphysis and adductor, or mixed. RESULTS: Overall, 47 studies published between 1991 and 2020 were included. There were 2737 patients (94% male) with a mean age at surgery of 27.8 years (range, 12-65 years). The mean duration of symptoms was 13.1 months (range, 0.3-144 months). The most frequent sport involved was soccer (71%), followed by rugby (7%), Australian football (5%), and ice hockey (4%). Of the 47 articles reviewed, 44 were classified as level 4 evidence, 1 study was classified as level 3, and 2 randomized controlled trials were classified as level 1b. The quality of the observational studies improved modestly with time, with a mean MINORS score of 6 for articles published between 1991 and 2000, 6.53 for articles published from 2001 to 2010, and 6.9 for articles published from 2011 to 2020. Return to play at preinjury or higher level was observed in 92% (95% CI, 88%-95%) of the athletes after surgery to the inguinal area, 75% (95% CI, 57%-89%) after surgery to the adductor origin, 84% (95% CI, 47%-100%) after surgery to the pubic symphysis, and 89% (95% CI, 70%-99%) after combined surgery in the inguinal and adductor origin. CONCLUSION: Return to play at preinjury or higher level was more likely after surgery for inguinal-related CGP (92%) versus adductor-related CGP (75%). However, the majority of studies reviewed were methodologically of low quality owing to the lack of comparison groups.

RESUMEN

BACKGROUND AND PURPOSE: The nervous system plays a significant role in groin/hip flexor pain which is a common complaint in the active population. Patient examinations that lack consideration of the nervous system's involvement may result in chronic pain and dysfunctional breathing patterns due to continuously excited (also known as "up-related") primal reflexes. Primal Reflex Release Technique™ (PRRT™) is a novel treatment paradigm that was designed to calm primal reflexes from their excitatory state. The purpose of this case series was to describe the effects of down-regulating primal reflexes using PRRT™ on pain, function, and breathing pattern dysfunction in subjects who presented with groin and hip flexor pain and exhibited hyperesthesia to TriggerRegions™ in areas of respiration. CASE DESCRIPTIONS: Six subjects with acute groin and/or hip flexor pain were examined using a battery of tests including muscle integrity strength and range-of-motion (ROM) measurements, special orthopedic tests, breathing functionality and PRRT™ rib palpation assessments. If subjects were determined to be potential PRRT™ responders through PRRT™ rib palpation assessments, the technique was performed according to PRRT™ guidelines. Outcome measures including the Numeric Pain Rating Scale (NPRS), Patient Specific Functional Scale (PSFS), the Global Rating of Change (GRoC) Scale, and the Disability in the Physically Active (DPA) Scale were collected to determine the effects of the treatment. OUTCOMES: All subjects demonstrated full resolution of pain as reported on the Numeric Pain Rating Scale, and the change was statistically (p = 0.001) and clinically significant. All subjects returned to optimal function as reported on the Patient Specific Functional Scale, and the change was both clinically (minimal detectable change) and statistically significant (p = 0.001). All subjects returned to normal breathing function as observed through the seated assessment of lateral expansion test. The number of treatments (mean = 1.83 ± 1.16) and time to the resolution of symptoms was minimal (mean = 2.833 ± 2.56 days). DISCUSSION: By assessing and treating abnormal breathing patterns, postulated to be a result of a sustained excitatory nervous system, subjects returned to full activity, without pain, in less than three days. After a two-week follow-up, subjects remained functionally pain free. Considering the state of the nervous system in the presentation of musculoskeletal pain and not focusing all treatment on local muscle structures may be beneficial. A multifaceted assessment approach is needed to determine other pain factors. LEVEL OF EVIDENCE: Level 4.

RESUMEN

STUDY DESIGN: Resident's case problem. BACKGROUND: Groin pain represents a diagnostic challenge and requires a diagnostic process that rules out life-threatening illness or disease processes. Osteomyelitis is a potential fatal disease process that requires accurate diagnosis and medical management. Osteomyelitis presents a problem for the outpatient physical therapist, as the described physical findings for the diagnosis of osteomyelitis are nonspecific. DIAGNOSIS: A 67-year-old man with groin and bilateral medial thigh pain was referred for physical therapy care to address right adductor weakness and generalized deconditioning. He had undergone extensive treatment for bladder cancer, with a recent radical cystoprostatectomy and cutaneous urinary diversion with an Indiana pouch. Postsurgical magnetic resonance imaging indicated normal findings, and the patient was currently being managed by an orthopaedic surgeon, who diagnosed the patient as having obturator nerve palsy. The physical therapist's examination produced findings inconsistent with this diagnosis. Subsequently, nuclear medicine studies revealed pubic symphysitis/osteomyelitis with secondary myositis, predominantly affecting the right adductor muscles. DISCUSSION: Osteomyelitis represents a difficult problem for the outpatient physical therapist. Careful consideration of red-flag symptoms and inconclusive physical testing indicate the need for further medical work-up. In this case, appropriate medical management led to improvement in patient function, highlighting the need for early diagnosis. LEVEL OF EVIDENCE: Differential diagnosis, level 4.
