Adductor insertion avulsion

OBJECTIVE: "Thigh splints," also known as the adductor insertion avulsion syndrome, is a painful condition affecting the proximal to mid femur at the insertion of the adductor muscles of the thigh. Scintigraphic findings in this syndrome have been described; we report a spectrum of MR imaging abnormalities involving this portion of the femur in a group of patients presenting with hip, groin, or thigh pain. CONCLUSION: Symptoms of vague hip, groin, or thigh pain may be associated with stress-related changes in the proximal to mid femoral shaft (thigh splints)...

OBJECTIVE: The objective of this study was to review the imaging appearance of the femurs of five patients who had been referred from outside institutions after presenting with thigh pain and being given a preliminary diagnosis of primary malignant bone tumor. Typically, when making a diagnosis, physicians place emphasis on the characteristic appearances of diseases on MR imaging, but such appearances may be misleading. An awareness of the specific MR imaging pattern of stress-related partial muscle avulsion can lead to the correct diagnosis...

We reviewed the records and radiographs of seven children who presented with knee pain, local tenderness over the medial femoral condyle, and radiological irregularity of the distal medial metaphysis of the femur suggestive of malignancy. In the five patients who had biopsies, histological changes were consistent with musculotendinous avulsion, and the dissection of ten cadavers confirmed the site to be the insertion of part of the adductor magnus. The recognition of this lesion and knowledge of its benign nature may avoid unnecessary anxiety and needless biopsy...

Acute ulnar instability of the metacarpophalangeal joint of the thumb is divided into two distinct groups, according to the history, clinical, radiological and operative findings. In the first group it is a soft tissue injury, as a result of an unresisted abduction force to the thumb. In the second group, following a resisted abduction force, there is avulsion of a bony fragment from the base of the proximal phalanx, which is the site of common insertion of both the ulnar collateral ligament and the adductor pollicis...

The posteromedial aspect of the distal end of the femur in the area of insertion of the adductor magnus is the site of occurrence of a developmental defect that may have the roentgenographic characteristics of a malignant bone tumor. As it is asymptomatic, this common defect is almost always an incidental finding, but it has been confused with osteosarcoma. The lesion is thought to be due to trauma or the avulsion of small bits of bone at the site of insertion of the adductor magnus muscle. Histologically the lesion has been mistaken for osteosarcoma because of the immature reactive bone and fibrous tissue presnet...

A case is reported of a hematoma developing between the tunica albuginea of the cavernous bodies and the deep fascia of the penis, following traumatic avulsion of the region of insertion of the adductor muscles of the right lower limb. The interesting feature of this case, a type apparently not reported previously, was the suggested differential diagnosis of early priapism.

Stress fracture is common in military recruits, joggers, and runners. Stress fracture in the pubic ramus is not common, and it constitutes only 1.25% of all stress fractures. A stress fracture, avulsion type of the pubis at the insertion of adductor magnus on an active swimmer is reported here.

Shin splints is a defined clinical entity resulting from extreme tension on muscles inserting on the tibia, resulting in periosteal elevation which is detectable by bone scanning. The clinical equivalent in the thigh has been described. We found scintigraphic changes in the femurs of seven short, female, basic trainees at the Fort Dix Army base, most of whom were referred for stress fractures elsewhere in the lower extremities. The scan findings were generally noted in the upper or mid femurs, always involved the anteromedial cortex, and were bilateral in five of the seven subjects...

An exercise-related avulsion injury of the insertion of the pectineus muscle is described. The abnormality was detected on a 4-hour delayed bone scan. Symptomatic injuries of the adductor muscles are uncommon and are not to be confused scintigraphically with a stress fracture of the proximal femoral shaft.

Treatment of spastic dysphonia by recurrent laryngeal nerve section has resulted in reproducibly good results in the early postoperative period in most patients. However, critical long-term follow-up has shown a high recurrence rate of adductor spasms by the third year after initial nerve section. A patient who developed recurring adductor spasms 1 year after nerve section was reexplored, with identification of neural regrowth into the distal segment of the recurrent laryngeal nerve. The technique of neural avulsion removing the distal nerve up to its insertion into the laryngeal muscles is described...

A review is presented here of 36 cases, seen since 1980, of acute Grade III (unstable) sports-related sprains of the thumb metacarpophalangeal joint. In all cases, the injury involved the ulnar collateral ligament. A Stener lesion was present in 97% of cases. Followup was from 2.0 to 8.5 years, the average being 3.9 years. All of the patients underwent repeat examination and radiography at followup. The first seven patients were treated by "traditional" pull-out suture and K-wire fixation, put into a cast for 4 weeks, and then gradually mobilized over 4 additional weeks...

There has been increasing interest within the European sports medicine community regarding the etiology and treatment of groin pain in the athlete. Groin pain is most commonly caused by musculotendinous strains of the adductors and other muscles crossing the hip joint, but may also be related to abdominal wall abnormalities. Cases may be termed "pubalgia" if physical examination does not reveal inguinal hernia and there is an absence of other etiology for groin pain. We present nine cases of patients who underwent herniorrhaphies for groin pain...
