Participation in the sport of rowing has been steadily increasing in recent decades, yet few studies address the specific injuries incurred. This article reviews the most common injuries described in the literature, including musculoskeletal problems in the lower back, ribs, shoulder, wrist and knee. A review of basic rowing physiology and equipment is included, along with a description of the mechanics of the rowing stroke. This information is necessary in order to make an accurate diagnosis and treatment protocol for these injuries, which are mainly chronic in nature. The most frequently injured region is the low back, mainly due to excessive hyperflexion and twisting, and can include specific injuries such as spondylolysis, sacroiliac joint dysfunction and disc herniation. Rib stress fractures account for the most time lost from on-water training and competition. Although theories abound for the mechanism of injury, the exact aetiology of rib stress fractures remains unknown. Other injuries discussed within, which are specific to ribs, include costochondritis, costovertebral joint subluxation and intercostal muscle strains. Shoulder pain is quite common in rowers and can be the result of overuse, poor technique, or tension in the upper body. Injuries concerning the forearm and wrist are also common, and can include exertional compartment syndrome, lateral epicondylitis, deQuervain's and intersection syndrome, and tenosynovitis of the wrist extensors. In the lower body, the major injuries reported include generalised patellofemoral pain due to abnormal patellar tracking, and iliotibial band friction syndrome. Lastly, dermatological issues, such as blisters and abrasions, and miscellaneous issues, such as environmental concerns and the female athlete triad, are also included in this article.Pathophysiology, mechanism of injury, assessment and management strategies are outlined in the text for each injury, with special attention given to ways to correct biomechanical or equipment problems specific to rowing. By gaining an understanding of basic rowing biomechanics and training habits, the physician and/or healthcare provider will be better equipped to treat and prevent injuries in the rowing population.

A few cases of unilateral pediculolysis combined with contralateral spondylolysis have been reported, and most of them were related to athletic activities. A case of unilateral spondylolysis combined with contralateral lumbar pediculolysis in a military parachutist is reported. A 34-year-old man experienced low back pain and right sciatica for 3 months. Radiographs revealed a left spondylolysis combined with a right pediculolysis of the L5 vertebra. The patient had parachuted >300 times in the last 5 years. Interbody fusion of L5-S1 was performed, and the patient was free of pain after surgery.

Approximately 50% of adolescent athletes with persistent lumbar pain can be diagnosed with spondylolysis or spondylolisthesis. The remaining 50% will have suffered injury of the vertebral body, intervertebral disc, ring apophysis, pelvis, articular processes, spinous processes, interspinous ligament, or other soft tissues of the lumbar spine. The adolescent spine is prone to these injuries as a consequence of the growth spurt and skeletal immaturity. Accurate diagnosis is mandatory in order to achieve successful treatment. History, physical examination, imaging modalities, and precision spinal injections can be employed to accurately diagnose the source of the symptoms. Appropriate treatment measures can then be prescribed to optimally treat the adolescent spine injury.

Youth sports participation carries an inherent risk of injury, including overuse injuries. Little leaguer's shoulder, a stress fracture of the proximal humerus that presents as lateral shoulder pain, usually is self-limited. Little leaguer's elbow is a medial stress injury; treatment consists of complete rest from throwing for four to six weeks followed by rehabilitation and a gradual throwing program. Spondylolysis is a stress fracture of the pars interarticularis. Diagnostic modalities include plain film radiography, bone scan, computed tomography, single photon emission computed tomography, and magnetic resonance imaging. Treatment usually is conservative. Spondylolisthesis is the forward or anterior displacement of one vertebral body over another and may be related to a history of spondylolysis. Diagnosis is made with plain film radiography and graded according to the amount of displacement. Osgood-Schlatter disease presents as anterior knee pain localized to the tibial tubercle. Diagnosis is made clinically, and most patients respond to conservative measures. Calcaneal apophysitis (or Sever's disease) is a common cause of heel pain in young athletes, presenting as pain in the posterior aspect of the calcaneus.

Degenerative-inflammatory lumbar spinal pathology is one of the most common reasons why individuals seek medical care, and low back pain is the main symptom among those most commonly associated with this pathologic condition. Pain is commonly attributed to degenerative disc disease, particularly herniated discs, but many different spinal and perispinal structures may undergo degenerative-inflammatory phenomena and produce pain: discs, bone, facet joints, ligaments and muscles. In particular, in patients with non-radicular low back pain, this syndrome may arise from changes of the posterior elements/perispinal tissues of the lumbar spine (i.e., the "posterior vertebral compartment"). They include: facet joint pathology (e.g., osteoarthritis, joint effusion, synovitis and synovial cysts), spondylolysis, spinal/perispinal ligamentous degenerative-inflammatory changes and perispinal muscular changes. It is well known that magnetic resonance is the most sensitive imaging method for the evaluation of spinal degenerative pathology, even in the initial stages of the disease. T2-weighted sequences with fat saturation, and when indicated the use of contrast-enhanced T1-weighted images with fat saturation, permit the visualization of degenerative-inflammatory changes of the posterior elements of the lumbar spine that in most cases would have been overlooked with conventional non-fat suppressed imaging.

Spondylolysis and spondylolisthesis are often diagnosed in children presenting with low back pain. Spondylolysis refers to a defect of the vertebral pars interarticularis. Spondylolisthesis is the forward translation of one vertebral segment over the one beneath it. Isthmic spondylolysis, isthmic spondylolisthesis, and stress reactions involving the pars interarticularis are the most common forms seen in children. Typical presentation is characterized by a history of activity-related low back pain and the presence of painful spinal mobility and hamstring tightness without radiculopathy. Plain radiography, computed tomography, and single-photon emission computed tomography are useful for establishing the diagnosis. Symptomatic stress reactions of the pars interarticularis or adjacent vertebral structures are best treated with immobilization of the spine and activity restriction. Spondylolysis often responds to brief periods of activity restriction, immobilization, and physiotherapy. Low-grade spondylolisthesis (< or =50% translation) is treated similarly. The less common dysplastic spondylolisthesis with intact posterior elements requires greater caution. Symptomatic high-grade spondylolisthesis (>50% translation) responds much less reliably to nonsurgical treatment. The growing child may need to be followed clinically and radiographically through skeletal maturity. When pain persists despite nonsurgical interventions, when progressive vertebral displacement increases, or in the presence of progressive neurologic deficits, surgical intervention is appropriate.

Spondylolysis is a common entity, a minority of people affected by this disease need medical care, and only a few require surgery. Reconstruction of the pars interarticularis is an interesting alternative to segmental fusion; this technique has the advantage of preserving segmental motion. Most authors report good results for young patients without intervertebral disk or facet degenerative changes. Moreover Louis also showed good to excellent results with his technique carried out among people who presented a satisfactory disk height (equal to two thirds of normal height). This could extend the number of patients for whom pars interarticularis repair could be proposed. In this study, the limit of reconstruction was set at grade 3 of the Pfirrmann's classification. The fixation of the isthmus was done with a new kind of pedicle screw hook system. This stable and strong device is easy to use, allows an anatomic pars interarticularis reconstruction of spondylolysis and avoids a postoperative bracing. Twenty-three patients were assessed in this study, the mean age at operation was 34 (range 16-52 years) and the average follow-up was for 59 months (range 6-113 months). Eight patients showed moderate degenerative disk disease before the surgery and 12 patients had a grade 1 spondylolisthesis. The visual analogical scale, the Oswestry disability index (ODI) and the modified Prolo score were used for assessment of pain and clinical outcome before and after surgery. The results were from "excellent" to "good" for twenty patients (87%) and "fair" for three of them (13%). The consolidation of the isthmus was assessed at the end of the study (CT-scan); the fusion rate was observed in 91%. Among patients aged less than 30 years results are from "good", to "excellent" in all cases and consolidation was always observed. All of them showed normal disc signal before the surgery. In the group aged more than 30 years, the results varied from "good" to "excellent' in 73% and fusion of the defect was discovered in 82% of cases. Eight of them (73%) had moderate disk signal modification before the surgery. All people with fair results displayed moderate disk degeneration signs at MRI before surgery; but two of those three patients had a failure of defect consolidation too and it is also associated with poor results by several authors. No complication was found in this series. According to the good results reported by Louis and upto the current finding, the authors believe that pars interarticularis repair can be carried out on patients with moderate degenerative disk disease; the stage 3 of Pfirrmann's classification seems a good limit. The Bone and joint research (B.J.R. system) is readily usable by any surgeon using pedicle screw systems and having a short learning curve. No device failure has been observed in this series.

Operative treatment of symptomatic spondylolysis is not common. Multiple surgical techniques have been described for direct repairs of the pars defects. Reported success rates are high, although few reports describe successful return to sports in athletes. The purpose of the study was to assess the outcome after bone grafting and fixation of pars interarticularis defects utilizing a modification of the previously described techniques of Scott and of Songer. A retrospective single-arm cohort study was performed at a single center. This article reports on three athletes with symptomatic spondylolysis or grade I spondylolisthesis unresponsive to conservative management who were treated with bone grafting and a screw-cable repair. The outcome measure was the return to sports activities. A retrospective chart and radiographic analysis was conducted on three athletes. Patients were assessed for return to sports, clinical evidence of return to functional activities, and radiographic evidence of healing of the pars defects. All three patients proceeded to radiographic and clinical success. All patients reported resolution of their preoperative pain and return to sports. One patient did require occasional anti-inflammatory drugs for episodic low back pain. The use of this modified cable-screw technique for symptomatic spondylolysis provided excellent clinical, radiographic, and functional results in this small cohort.

Background. The aim of the study is the evaluation of the spatial imaging computed tomography (3D CT) of lumbo-sacral spine after surgically treated spondylolistesis L5-S1 with the postero-lateral spondylodesis using autogenic bone grafts. <br /> Material and methods. Material comprises 9 patients treated surgically due to I degrees spondylolistesis caused by the L5 vertebra spondylolysis. In all cases postero-lateral spondylodesis was performed using autogenic bone grafts, taken from the iliac crest, placed on the transverse processes of the L5 vertebra and the sacral bone. The CT examination was performed in the period between 6 months up to 2 years after operation due to overloading lumbar pain.<br /> Results. The bone grafts was localized correctly in 8 patients. In 1 person the upper side of the one bone graft was localized incorrectly, on the prominent transverse processus of the S1 vertebra, instead of the L5 one. The spatial reconstruction reveal the presence of osteophytes surrounding the ends of the bone grafts or the localization the fissure of the arch. In 2 cases the bone grafts were bigger on the left side, and the wide lower ends were connected with the dorsal surface of the sacral bone and were connected with the shorten due to surgery iliac crest<br /> Conclusions. The CT examination with the use of the spatial option is very valuable in the lumbo-sacral spine imaging in patients treated with the postero-lateral spondylodesis due to spondylolisthesis L5-S1. The spatial images 3D CT are especially useful in imaging of the localization of the bone grafts, assessment of the wide of spinal canal and intervertebral foramens. The use of spatial imaging 3D is valuable supplement of standard CT examination in diagnosis of the patients complaining of the lumbar pain, treated surgically due to spondylolistesis.
