Abstract
Digital artery embolization and ulnar artery thrombosis are consequences of repetitive trauma and can lead to digit loss and debility from ischemia and cold intolerance. We postulate that an arterial autograft is a theoretically superior conduit to traditional saphenous vein, and report reconstruction with inferior epigastric artery. Three adult male smokers, ages 39 to 49 years, had severe digital ischemia and cold-induced vasospasm. Arteriograms confirmed occlusion of the distal ulnar artery without direct perfusion of the superficial palmar arch, distal digital artery embolization, and normal proximal vasculature. All reconstructions were performed from the distal most patent ulnar artery at the wrist to the superficial palmar arch (1 patient) or sequentially to the involved common digital arteries (2 patients), with inferior epigastric artery. Handling characteristics and size match between the arterial autografts and bypassed arteries was excellent. Patency has been confirmed with duplex scanning at follow-up of 8 to 24 months, with resolution of cold intolerance and successful digital preservation.

Abstract
Chronic exertional compartment syndrome is an overuse condition affecting primarily active, athletic people. Its etiology is unclear, but several theories have been proposed. The syndrome is characterized by recurrent, often severe muscle compartment pain that occurs with vigorous exercise and subsides with rest. Physical examination usually provides little helpful information. Compartment pressure measurement before and after exercise is the mainstay of objective diagnosis. Conservative management has been highly unsuccessful. Overall, considerable success can be expected from fasciotomy of the involved compartments followed by a rigorous rehabilitation program, though recurrence of symptoms is a reported complication. Recent research efforts have focused on the development of less invasive and more accurate diagnostic modalities and safer and more effective surgical procedures.

Abstract
This review focuses on many of the foot and ankle injuries commonly seen among dancers. These unique athletes place extreme demands on their musculoskeletal system and thereby face a variety of acute and overuse injuries. Conservative treatment is successful in the majority of cases, but these patients often continue to dance while healing--commonly prolonging and at times complicating treatment. When surgery is being contemplated, the dancer's performance level and expectations about returning to dance after surgery should be thoroughly explored. Foot and ankle surgeries that routinely yield good to excellent results in the general population can prematurely end a dancer's otherwise promising career. The physician must consider all these factors when designing an appropriate treatment plan for a dancer.

Abstract
The first case of an aneurysm of the femoral artery occupationally exposed to a vibratory tool is described. A 72-year-old man with a right common femoral artery aneurysm had had an occupational history of putting a "breaker," which breaks concrete into pieces by means of powerful vibration, on the right groin for more than 10 years. The patient underwent aneurysmectomy and graft replacement, with reconstruction of the deep femoral artery. Pathologic examination of the resected aneurysm revealed fibrosis and lipid deposition in the intima, well-maintained elastic fibers without disruption in the media, and thickened adventitia, in place of the typical findings of atherosclerosis.

Abstract
Thromboembolic complications after arthroscopic shoulder surgery are very unusual and need thorough investigation of the possible origin. In this case of venous pulmonary thromboembolism after arthroscopy of the shoulder, neither a hint of coagulopathy nor an anatomic abnormality could be found that explains this complication. Therefore, irritation of the subclavian vein caused by compression by the motor-driven shaver is probably one cause for our thromboembolic complication. Careful attention to positioning, fluid management, and use of traction, as well as an appreciation of shoulder anatomy to select portal placement will help decrease the common complications associated with shoulder arthroscopy. A further option to prevent thrombembolic complications in shoulder arthroscopy patients might be prophylaxis with a low-weight heparin in patients with risk factors. In conclusion, awareness of uncommon complications such as deep venous thrombosis and pulmonary embolism will help the orthpaedic surgeon promptly diagnose and treat these problems.

Abstract
BACKGROUND Medial tibial stress syndrome is a common chronic sports injury characterized by exercise-induced pain along the posteromedial border of the tibia. The reported outcomes of surgical treatment of this condition have varied. METHODS Of seventy-eight patients who underwent surgery for medial tibial stress syndrome, forty-six (thirty-one men and fifteen women) returned for follow-up. The outcomes of the surgery were determined by comparing preoperative and postoperative pain levels as indicated on a visual analog pain scale and ascertaining the ability of the athletes to return to presymptom levels of exercise. RESULTS The mean duration of postoperative follow-up was thirty months (range, six to sixty-three months). Surgery significantly reduced pain levels (p < 0.001) by an average of 72% as indicated on the visual analog pain scale. An excellent result was achieved in 35% of the limbs; a good result, in 34%; a fair result, in 22%; and a poor result, in 9%. Despite the success with regard to pain reduction, for a variety of reasons only nineteen (41%) of the athletes fully returned to their presymptom sports activity. CONCLUSIONS Surgery can significantly reduce the pain associated with medial tibial stress syndrome. Despite this reduction in pain, athletes should be counseled that a full uninhibited return to sports is not always achieved.

Abstract
Upper extremity arterial injury resulting in hand and digit ischemia can occur in athletes who perform repetitive, high-stress, overhead arm motions. The initial presentation of these injuries often mimics the more common musculoskeletal injuries found in these athletes, and therefore, a high index of suspicion is essential to establish the diagnosis in a timely fashion. There are several described mechanisms of injury, most of which involve extrinsic compression and injury to the axillary artery or its branches from the humeral head. The clinical diagnosis is confirmed with noninvasive vascular laboratory testing, and the anatomy is generally confirmed using contrast arteriography. Surgical repair is almost always successful in these patients, allowing full recovery with return to competition.

Abstract
The focus in overhead sport injuries of the shoulder has been directed on lesions of the superior labrum-biceps complex during the last few years. This is due to improved imaging modalities as well as a better understanding of the anatomy and biomechanics. Arthroscopy is capable of diagnosing and treating these lesions. The anatomy, biomechanics, and operative treatment strategies and techniques are described in detail. The superior labrum anterior-posterior (SLAP) lesion is found in young active overhead athletes. Based on their classification and concomitant lesions, the unstable SLAP lesions (types II and IV) have to be repaired in order to restore stability to the superior labrum-biceps complex for stabilizing the glenohumeral joint. According to our own results and after review of the current literature, SLAP repair yields good results in overhead athletes enabling them to return to pain-free participation in their sport.

Abstract
PROLOGUE: Several years ago, when we began to question microinstability as the universal cause of the disabled throwing shoulder, we knew that we were questioning a sacrosanct tenet of American sports medicine. However, we were comfortable in our skepticism because we were relying on arthroscopic insights, clinical observations, and biomechanical data, thereby challenging unverified opinion with science. In so doing, we assembled a unified concept of the disabled throwing shoulder that encompassed biomechanics, pathoanatomy, kinetic chain considerations, surgical treatment, and rehabilitation. In developing this unified concept, we rejected much of the conventional wisdom of microinstability-based treatment in favor of more successful techniques (as judged by comparative outcomes) that were based on sound biomechanical concepts that had been scientifically verified. Although we have reported various components of this unified concept previously, we have been urged by many of our colleagues to publish this information together in a single reference for easy access by orthopaedic surgeons who treat overhead athletes. We are grateful to the editors of Arthroscopy for allowing us to present our view of the disabled throwing shoulder. Part I: Pathoanatomy and Biomechanics is presented in this issue. Part II: Evaluation and Treatment of SLAP Lesions in Throwers will be presented in the May-June issue. Part III: The "SICK" Scapula, Scapular Dyskinesis, the Kinetic Chain, and Rehabilitation will be presented in the July-August issue. We hope you find it thought-provoking and compelling.

Abstract
OBJECTIVE To compare the outcome of chronic patellar tendinopathy treated surgically and by extracorporeal shock wave therapy. DESIGN Cross-sectional outcome analysis. SETTING University Hospital Pellenberg, Leuven, Belgium. PATIENTS AND INTERVENTIONS Of a total of 27 patients (28 knees) with chronic patellar tendinopathy, 13 were treated surgically, and 14 (15 knees) received extracorporeal shock wave therapy. MAIN OUTCOME MEASUREMENTS Functional outcome questionnaire: Victorian Institute of Sport Assessment score, Visual Analog Scale, and Roles and Maudsley classification. RESULTS At an average of 6 months of follow-up, the mean Victorian Institute of Sport Assessment and Visual Analog Scale scores for the extracorporeal shock wave therapy group were 78.8 +/- 28.7 and 9 +/- 2, respectively, which improved to 83.9 +/- 28.6 and 9 +/- 2, respectively, at 22.1 months. The surgery group scored 70.7 +/- 22.2 points on the Victorian Institute of Sport Assessment at an average of 26.3 months of follow-up (p = 0.41 and p = 0.18) and 8 +/- 3 on the Visual Analog Scale (p = 0.14). In the extracorporeal shock wave therapy group, 5 (33%) patients rated their pain status at 22.1 months as excellent, 5 (33%) as good, 2 (13%) as fair, and 2 (13%) as poor. In the surgery group, 4 (33%) evaluated the result as excellent, 3 (25%) as good, 3 (25%) as fair, and 2 as poor (17%). CONCLUSIONS Extracorporeal shock wave therapy shows a comparable functional outcome to surgery in a cross-sectional analysis of patients with chronic proximal patellar tendinopathy resistant to conservative treatment.

Abstract
Iliotibial band friction syndrome (ITBFS) is a common overuse injury reported to afflict 1.6% to 12% of runners. It results from an inflammatory response secondary to excessive friction that occurs between the lateral femoral epicondyle and the iliotibial band. Initial treatments include rest, anti-inflammatory medication, modalities (ice or heat), stretching, physical therapy, and possibly a cortisone injection. In recalcitrant cases of ITBFS, surgery has been advocated. This report describes a surgical technique of Z-lengthening of the iliotibial band in patients presenting with lateral knee pain localized to the iliotibial band at the lateral femoral epicondyle and Gerdy's tubercle who failed all nonoperative efforts.

Abstract
Various authors have highlighted the importance of the dorsal radiocarpal (DRC) ligament in normal carpal kinematics. It is a secondary stabilizer of the lunate and has a role in midcarpal stability. Disruption of the DRC ligament has been implicated in the development of static VISI and DISI deformities, prompting some authors to perform an open reattachment of the dorsal capsule if there is an associated scapholunate ligament tear. The management of these tears is still evolving. The contribution of a DRC ligament tear to the development of wrist pain remains uncertain when combined with additional wrist pathology. An isolated DRC ligament tear was responsible for chronic dorsal wrist pain in 2 patients. A previously undescribed inside-out repair method of the DRC ligament using a volar wrist portal was successful in relieving the pain. Recognition of this condition and further research into treatment methods is needed.

Abstract
The purpose of this study is to evaluate arthroscopic ulnar shortening with the holmium:yttrium-aluminum-garnet (Ho:YAG) laser for the treatment of ulnocarpal abutment syndrome (UAS). This is a retrospective review of the experience of a single surgeon using this technique between 1994 and 2000. Unloading the ulnocarpal joint is the recognized treatment of UAS. Ulnar shortening via a diaphyseal osteotomy and plating (USO) has been used with good results; however, nearly 50% of patients will require hardware removal. Researchers have reported similar results between open distal ulnar resection (the wafer procedure) and USO for the treatment of UAS. Researchers have also reported similar results with mechanical arthroscopic distal ulnar resections (arthroscopic wafer distal ulnar resection [AWP]) for UAS. Eleven patients who underwent Ho:YAG laser-assisted arthroscopic distal ulnar resection were retrospectively evaluated. The average follow-up time was 31 months, with a range of 7 to 61 months. Evaluation using Darrow' s criteria revealed 64% excellent (7 of 11), 18% good (2 of 11), 9% fair (1 of 11), and 9% poor (1 of 11) results. The average return to work time was 4.7 months, with a range of 1.5 to 16 months. Complications included 1 repeat surgery for ulnocarpal scar formation, 2 cases of transient tendonitis, and 1 portal site erythema without drainage that was treated with antibiotics. One patient (the one with a poor result) has not returned to work for unrelated reasons. chi- square analysis (P <.05) was unable to identify a statistical difference between the reported results of arthroscopic wafer procedures, USOs, and open wafer procedures. We concluded that Ho:YAG laser-assisted arthroscopic ulna shortening procedures show similar results to those reported for arthroscopic wafer procedures, open wafer procedures, and USOs. Return to work times are similar to those reported by other researchers, as is the return to preoperative occupation rate. There is no need for late removal of hardware, as is sometimes associated with USO. Our experience has been that the Ho:YAG laser removes hyaline cartilage and subchondral bone rapidly and with little debris, and thus facilitates the ulna shortening procedure.

Abstract
The hypothenar hammer syndrome (HHS) is a rare form of secondary Raynaud's phenomenon in workers who frequently use the ulnar side of the palm as a hammer. Clinically the patient with HHS shows neurologic symptoms such as paresthesia, numbness and pain and signs of vascular insufficiency such as coldness, pallor, discoloration and blanching of the affected ulnar sided fingers. The diagnosis is verified by angiography, showing thrombosis or aneurysm of the distal ulnar artery. We report on the treatment and outcome of 5 patients with HHS. All patients were painfree after treatment. But with the ongoing working habit of using the hand as a hammer there is always the risk of a recurrence. Therefore the job environment has to be changed considerably and the most effort should go into prevention and prophylaxis. If the change of the working habit is not possible, the job is clearly at stake.

Abstract
The case of a 27-year-old overhead athlete with chronic shoulder pain because of an isolated subscapularis tear without trauma is described. Arthroscopy has proven to be the appropriate method for detailed visualisation of the injury and facilitates the operative planning. Furthermore, arthroscopy closes the problem of a "diagnostic gap". In the presented case, the results at the two year follow-up are excellent. The authors conclude that an operative approach is also justified in non-traumatic isolated ruptures of the subscapularis muscle.

Abstract
OBJECTIVE Our goal was to evaluate the long-term results of vein bypass grafts for axillary artery occlusion, specifically those placed extra-anatomically to prevent arterial injury in pitchers. METHODS With the greater saphenous veins used as the selected conduit, arterial bypass grafts were routed anterior to the pectoralis minor muscle in four baseball pitchers who had occlusion of the axillary artery. We performed a follow-up in excess of 10 years with evaluations of the bypass grafts by ultrasonic duplex scan and magnetic resonance angiography. RESULTS All four pitchers treated in this manner returned to the game and played for several seasons without a recurrence of the arterial injury. Long-term evaluation of the bypass grafts did not reveal any structural or functional disorder. CONCLUSIONS Axillary artery occlusion in an athlete can be effectively treated with a vein bypass graft placed extra-anatomically, anterior to the pectoralis minor muscle. The greater saphenous vein should be considered the conduit of choice.

Abstract
PURPOSE The purpose of this study was to evaluate the outcome of arthroscopic distal clavicle resection by the direct superior approach for treatment of isolated osteolysis of the distal clavicle. TYPE OF STUDY Case series. MATERIALS AND METHODS Forty-one shoulders in 37 patients underwent arthroscopic resection of the distal clavicle. Thirty-three patients were male and 4 female, with an average age of 39 years. All patients complained of pain localized to the acromioclavicular joint region. Symptoms began after a traumatic event in 18 shoulders and were associated with repetitive stressful activity in 23 shoulders. RESULTS At an average follow-up of 6.2 years, 22 shoulders had excellent results, 16 had good results, and 3 were failures. All 3 failures occurred in patients with a traumatic etiology. CONCLUSIONS Arthroscopic resection for osteolysis of the distal clavicle has results comparable to open excision with low morbidity. Patients with a traumatic etiology had slightly worse results compared with patients with a microtraumatic etiology.

Abstract
PURPOSE Finger ischemia caused by embolic occlusion of digital arteries originating from the palmar ulnar artery in a person repetitively striking objects with the heel of the hand has been termed hypothenar hammer syndrome (HHS). Previous reports have attributed the arterial pathology to traumatic injury to normal vessels. A large experience leads us to hypothesize that HHS results from trauma to intrinsically abnormal arteries. METHODS We reviewed the arteriography, histology, and clinical outcome of all patients treated for HHS in a university clinical research center study of hand ischemia, which prospectively enrolled more than 1300 subjects from 1971 to 1998. RESULTS Twenty-one men had HHS. All had occupational (mechanic, carpenter, etc) or avocational (woodworker) exposure to repetitive palmar trauma. All patients underwent upper-extremity and hand arteriography, unilateral in eight patients (38%) and bilateral in 13 patients (62%). By means of arteriogram, multiple digital artery occlusions were shown in the symptomatic hand, with either segmental ulnar artery occlusion in the palm or characteristic "corkscrew" elongation, with alternating stenoses and ectasia. Similar changes in the contralateral asymptomatic (and less traumatized) hand were shown by means of 12 of 13 bilateral arteriograms (92%). Twenty-one operations, consisting of segmental ulnar artery excision in the palm and vein grafting, were performed on 19 patients. Histology was compatible with fibromuscular dysplasia with superimposed trauma. Patency of arterial repairs at 2 years was 84%. One patient (5%) required amputative debridement of necrotic finger tips. No other tissue loss occurred. There have been no recurrences of ischemia in patients with patent bypass grafts. CONCLUSION To our knowledge, this is the largest reported group of HHS patients. The characteristic angiographic appearance, histologic findings, and striking incidence of bilateral abnormalities in patients with unilateral symptoms lead us to conclude that HHS occurs when persons with preexisting palmar ulnar artery fibrodysplasia experience repetitive palmar trauma. This revised theory for the etiology of HHS explains why HHS does not develop in most patients with repetitive palmar trauma.

Abstract
Almost all operations that were traditionally performed by open laparotomy operations can be done laparoscopically; however, surgeons may experience several negative health effects. A 37-year-old gynecologic laparoscopist had a herniated intervertebral disk at C5-6 level. Due to a negative trauma history, a possible explanation may be the nonergonomic posture that he held while performing laparoscopic surgery for many hours. To reduce the risk of this complication, we recommend that surgeons' spatial orientation and hand-eye coordination for laparoscopy be improved by sequential phases of training.
