RESUMEN
BACKGROUND AND AIMS: Stress fractures are common overuse injuries in athletes. Medial malleolar stress fractures are rare but they have an important clinical relevance because of their tendency to cause considerable disability and loss of time in sports without proper treatment. The diagnosis of medial malleolar stress fracture is often a challenge and it is therefore often delayed which may cause even further problems in the treatment. The purpose of this study was to increase the awareness of medial malleolar stress fractures as a possible cause for medial ankle pain and to stress the importance of MRI in the diagnostics as well as to evaluate the results of surgical treatment. PATIENTS AND METHODS: Between 1995 and 2008, a total of ten athletes with a medial malleolar stress fracture were operated at our centre. All operated cases during those years were included in the study. The cases were retrospectively analyzed. Return to pre-injury level of sport was evaluated and considered as an indicator of successful treatment. RESULTS: Initially all standard radiographs were negative whereas in MRI the fractures were all visible. After operative treatment all medial malleolar stress fractures healed clinically in three to four months and all except one of the athletes were able to return to their pre-injury level of sports. CONCLUSION: Early MRI is recommended if a medial malleolar stress fracture is suspected. Surgical treatment seems to result in rapid healing of the fracture and return to sports. In our opinion early surgery should be considered especially in athletes.

BACKGROUND AND AIMS: Achilles tendinopathy is a common problem that can cause disturbing symptoms in activities of daily living as well as prevent sports activities. The purpose of this study was to evaluate the effects of fascial incision and adhesiolysis combined with radiofrequency microtenotomy in treatment of chronic midportion Achilles tendinopathy. MATERIAL AND METHODS: Twenty-four patients were included in this study. The cases were studied retrospectively. The mean age of the patients was 54 years (range, 39 to 72) and there were 12 women and 12 men. A final evaluation was done at an average of 30 months (range, 18 to 45) after surgery, including radiofrequency microtenotomy. RESULTS: In all cases the Nirschl Pain Phase Scale of Athletic Overuse Injuries score improved and the difference was statistically significant (p < 0.0001). The patients themselves rated the result excellent in 14 cases and good in 10 cases. CONCLUSION: Fascial incision and adhesiolysis combined with radiofrequency microtenotomy seems to be a useful alternative in treatment of chronic midportion Achilles tendinopathy in cases of unsuccessful non-operative treatment.

BACKGROUND AND AIMS: An anterior mid-tibial stress fracture is an uncommon, but possibly career threatening condition for an athlete. We wanted to evaluate the results of the surgical treatment of this notorious stress fracture and compare two different surgical methods. MATERIAL AND METHODS: Forty-nine anterior mid-tibial stress fractures were treated surgically in 45 patients during the years 1985-2005. All the patients were athletes, mainly runners. The mean age of the patients was 26 years. Thirty-four of the fractures occurred in men and 15 in women. The first method of treatment (anteromedial and lateral drilling) was used in 20 operations and the second method (laminofixation) in 29 operations. RESULTS: Good results were achieved with drilling in only 50 % of the operations, where as with laminofixation good results were achieved in 93 % of operations. This difference was statistically significant (p = .002). Healing of the stress fracture after laminofixation occurred in less than 6 months. The length of the plate used in the laminofixation had no effect on the end result. CONCLUSIONS: An anterior mid-tibial stress fracture may often lead to delayed union or non-union in vigorously training athletes. Surgical treatment with laminofixation proved to be superior to tibial fracture site drilling.

Total proximal avulsions of the quadriceps femoris muscle group are rare injuries. Between the years 2001 and 2004 five patients with a total proximal avulsion of the tendon of the rectus femoris muscle were treated surgically in Mehiläinen Hospital in Turku, Finland. The median age of the patients was 21 years (range, 19-27) and the patients were all men. There were four soccer players and one hurdler. In all cases an avulsion of the proximal tendon of the rectus femoris muscle was confirmed by MRI. All of the patients were operated on and the delay from the injury to surgery ranged from 18 to 102 days. The result of the surgical treatment was rated good in all cases. All of the patients were able to return to their pre-injury level of activity 5-10 months after surgery. The median follow-up time was 20 months (range, 9-38). Surgical treatment of a total proximal avulsion of the tendon of the rectus femoris muscle seems to result in return to the pre-injury activity level in most cases.

Proximal stress fractures of the second metatarsal are rare. They have been reported mainly in classical ballet dancers. Non-operative treatment has usually led to good results and rapid return to full activities. We present a series of nine cases with stress fractures of the proximal second metatarsal. The patients were all actively involved in sports. None of them were dancers. In all of these patients non-operative treatment lasting for an average of 13 months had failed. All of the patients were operated on using the same method. In the operation drilling was performed around and through the fracture line. The patients were followed for an average of 38 months. All except one of the patients were able to return to their prior level of activity within 4-6 months. In conclusion if non-operative treatment fails surgery seems to give good results in most patients with a stress fracture of the proximal second metatarsal.

BACKGROUND: Hamstring injuries are common especially in athletes. Partial and complete tears of the proximal origin may cause pain and functional loss. OBJECTIVE: To evaluate the results of surgical treatment for partial proximal hamstring tears. METHODS: Between 1994 and 2005, 47 athletes (48 cases, 1 bilateral) with partial proximal hamstring tears were operated on. The cases were retrospectively analysed. Before surgery, 42 of the patients had undergone conservative treatment with unsatisfactory results, whereas in five patients the operation was performed within four weeks of the injury. RESULTS: The mean length of the follow up was 36 months (range 6-72). The result of the operation was rated excellent in 33 cases, good in nine, fair in four, and poor in two. Forty one patients were able to return to their former level of sport after an average of five months (range 1-12). CONCLUSION: In most cases, excellent or good results can be expected after surgical repair of partial proximal hamstring tears even after conservative treatment has failed.

The purpose of this study was to evaluate the events leading to acute traumatic extension deficit of the knee and the arthroscopic findings in these patients. A total of 78 consecutive patients treated in the Turku university hospital during the years 1994-1996 were included. The mean annual incidence of acute traumatic extension deficits of the knee in our study was 1.1 per 10 000 inhabitants. The single most common (33%) event causing the extension deficit was non-sports related twisting of the knee. Various sports related activities accounted for 42% of the extension deficits, and soccer was the most common sport in this group. In conclusion, acute traumatic extension deficit of the knee is usually a sign of serious intra-articular damage, and the most likely finding (in 82% of the patients in our study) is either a meniscal rupture, an anterior cruciate ligament (ACL) rupture, a patellar dislocation, or a combination of these. The lesions in these knees require prompt evaluation by an orthopaedic surgeon mainly because of the high number of bucket-handle and menisco-capsular insertion ruptures of the menisci, which are possibly suitable for repair.

OBJECTIVE: To prospectively assess the early results of surgical treatment of chronic Achilles tendinopathy. METHODS: This seven month prospective follow up study assessed the short term results of surgical treatment of chronic Achilles tendinopathy and compared the subjective and functional outcome of patients with Achilles tendinopathy without a local intratendinous lesion (group A) with that of similar patients with such a lesion (group B). Forty two of the initial 50 patients were examined before surgery and after the seven month follow up. Evaluation included an interview, subjective evaluation, clinical tests, and a performance test. RESULTS: At the follow up, physical activity was fully restored in 28 of the 42 patients (67%), and 35 patients (83%) were asymptomatic or had only mild pain during strenuous exercise. In clinical tests, significant improvements were observed in climbing up and down stairs and the rising on the toes test. Surgical treatment also seemed to be successful from the total test score, which was excellent or good in 35 patients, compared with before surgery when it was excellent or good in one patient only. Patients in group A fared better than those in group B, whether evaluated by recovery of physical activity after surgery (88% v 54%) or the complication rate (6% v 27%). CONCLUSIONS: Surgical treatment of chronic Achilles tendinopathy gives good and acceptable short term results. A lower complication rate and a trend to better recovery was observed in patients with peritendinous adhesions only than in those with peritendinous adhesions combined with an intratendinous lesion.

BACKGROUND AND AIMS: Distortions and contusions of the knee are common. Fairly often they will result in hemarthrosis. The purpose of this study was to evaluate the findings in patients with acute traumatic hemarthrosis of the knee and based on these findings estimate the necessity of acute arthroscopic examination. MATERIAL AND METHODS: A total of 320 patients were examined arthroscopically between the years 1994 to 96 in the Turku University Hospital. Patients with other than chondral or osteochondral fractures were excluded. RESULTS: The most common arthroscopic findings were rupture of the ACL (45%), dislocation of the patella (23%) and meniscal tear (21%). In only 113 (35%) cases an immediate therapeutic procedure was performed in addition to the arthroscopic examination. CONCLUSIONS: Based on our findings we believe that routine arthroscopic examination is not necessary in patients with acute traumatic hemarthrosis of the knee. In our opinion the patient should be examined and followed by an orthopedic surgeon and if a lesion requiring operative treatment is diagnosed or suspected, an arthroscopic examination should be scheduled. The timing of the procedure should be such that all possible lesions encountered can be treated in the same operation.

Our aim was to identify factors predisposing athletes to multiple stress fractures, with the emphasis on biomechanical factors. Our hypothesis was that certain anatomic factors of the ankle are associated with risk of multiple stress fractures of the lower extremities in athletes. Thirty-one athletes (19 men and 12 women) with at least three separate stress fractures each, and a control group of 15 athletes without fractures completed a questionnaire focusing on putative risk factors for stress fractures, such as nutrition, training history, and hormonal history in women. Bone mineral density was measured by dual-energy x-ray absorptiometry in the lumbar spine and proximal femur. Biomechanical features such as foot structure, pronation and supination of the ankle, dorsiflexion of the ankle, forefoot varus and valgus, leg-length inequality, range of hip rotation, simple and choice reaction times, and balance in standing were measured. There was an average of 3.7 (range, 3 to 6) fractures in each athlete, totaling 114 fractures. The fracture site was the tibia or fibula in 70% of the fractures in men and the foot and ankle in 50% of the fractures in women. Most of the patients were runners (61%); the mean weekly running mileage was 117 km. Biomechanical factors associated with multiple stress fractures were high longitudinal arch of the foot, leg-length inequality, and excessive forefoot varus. Nearly half of the female patients (40%) reported menstrual irregularities. Runners with high weekly training mileage were found to be at risk of recurrent stress fractures of the lower extremities.

BACKGROUND AND AIMS: Peroneal tendon injuries are probably frequently overlooked causes of lateral ankle pain after distorsion trauma. We report a series of 38 patients with peroneal tendon injuries and outcome after operation. MATERIAL AND METHODS: The mean age of the patients was 30 years (range, 13 to 61). All patients were operated by the same orthopaedic surgeon (SO) and the final outcome was evaluated. RESULTS: Eighty-two per cent of the patients were competitive athletes. There were 11 partial and 3 total ruptures of the peroneus brevis tendon (PBT), 2 partial and 2 total ruptures of the peroneus longus tendon (PLT). Nine cases of subluxations or luxations were treated. There were also 5 cases of chronic peroneal tendinitis or tenosynovitis, 5 cases of peroneal tendon anomalies and 1 ganglion. The peroneal tendon lesion was associated to ankle instability in 19 cases (50%). In ninety percent of the cases the result of the operation was excellent or good. CONCLUSIONS: The lateral ligaments are usually damaged in ankle distorsion injuries, but peroneal tendon lesions are often overlooked and probably more common cause of persistent lateral ankle pain than previously thought. Ruptures and luxations of the peroneal tendons need operative treatment in most cases.

The object was to study the relationships between calf muscle size and strength in 85 patients an average of 3.1 years after repair of achilles tendon rupture. The isokinetic calf muscle strength results were excellent or good for 73% of the patients, whereas calf muscle size was normal in only 30%. The average plantar flexion peak torque per unit muscle cross-sectional area was higher on the injured side than on the uninjured side. The average calf muscle cross-sectional area deficit was 15+/-9% (p<0.001) of that on the unaffected side, while the average plantar flexion peak torque deficit was speed-dependent, being 9+/-18%, 10+/-18 and 2+/-13% of that on the unaffected side at 30, 90, and 240 degrees/sec (p<0.001). The correlation between cross-sectional area and peak torque varied in the range 0.52-0.61 at 30, 90 and 240 degrees/sec (p<0.001).

We analyzed the complications after surgical treatment of Achilles tendon overuse injuries in 432 consecutive patients. The patients underwent a clinical examination 2 weeks, and 1, 2, and 5 months after the surgery. If a complication appeared, the patient was followed up clinically for at least 1 year. There were 46 (11%) complications in the 432 patients: 14 skin edge necroses, 11 superficial wound infections, 5 seroma formations, 5 hematomas, 5 fibrotic reactions or scar formations, 4 sural nerve irritations, 1 new partial rupture, and 1 deep vein thrombosis. Fourteen patients with a complication had reoperations: four patients for skin edge necrosis, two for superficial wound infection, two for seroma formation, one for hematoma formation, two for fibrotic reaction or scar formation, two for sural nerve irritation, and one for a new partial rupture. About every 10th patient treated surgically for chronic Achilles tendon overuse injury suffered from a postoperative complication that clearly delayed recovery. However, the majority of patients with a complication healed and returned to their preinjury levels of activity. To reduce this morbidity, it is essential that the surgeon be continuously aware of the possibility of postoperative complications and use proper surgical techniques.

BACKGROUND AND AIMS: We present our experience with surgical treatment of unresolved, painful, late Osgood-Schlatter disease. MATERIAL AND METHODS: In 70 operations performed in 67 patients (in three bilaterally) an ossicle under the distal patellar tendon was removed in 62 cases. In eight cases, excision of the prominent tibial tubercle and/or drilling of the epiphysis was performed. Additional procedures, such as rasping of the uneven anterior tibial surface, excision of inflammed bursa or the devitalized portion of the tendon, were done 21 times. Most patients were athletes or physically active young people. The mean age was 19.6 years. 54 operations were done on males and 16 on females. They had been followed preoperatively for 18 months and after surgery 2.2 years. RESULTS: The final results were excellent or good in 56, moderate in 9, poor in 3 and unknown in 2 cases. CONCLUSIONS: Osgood-Schlatter's disease may leave an ossicle under the distal patellar tendon, a prominent tibial tubercle or an uneven surface of anterior superior tibia. These may lead to pain and disability due to recurrent injuries or athletic exercises. Surgical treatment gives good results in chronic unresolved cases.

We present a series of 19 avulsions of the distal tendon of the biceps brachii muscle after a follow-up of 2 to 11 years. Ten patients with delayed diagnosis and treatment (3 weeks to 5 months) were compared with nine patients treated early (within 8 days after injury). Excellent or good results at follow-up were obtained in 9 of 10 patients in the delayed-treatment group and in all 9 patients in the early-treatment group. Nine of 10 patients in the delayed-treatment group and all patients in the early-treatment group had been able to return to their preinjury levels of activity. For reference, a meta-analysis of 147 cases reported previously was performed. Ninety percent of the patients treated with an anatomic reinsertion had excellent or good results after an average follow-up of 3 years, while similar results after 3 years were seen in 60% of the patients who had nonanatomic tendon reinsertion and in 14% of the patients who were treated nonoperatively. The delay of up to 3 years between injury and anatomic reinsertion had not compromised the result. From these data we concluded that anatomic reinsertion of the avulsed distal biceps tendon to the radius is the preferred treatment in acute as well as chronic injuries.

We investigated the prognosis of low-back pain and the association of clinical symptoms and anatomic findings among young athletes. Consecutive patients, aged between 12 and 18 years, who had low-back pain that had interfered with their training for at least 4 weeks were included in the case series. All the patients participated in a standardized interview and clinical examination, and plain radiographs and magnetic resonance images were also obtained. Most patients also participated in technetium bone scan examination. In 15 out of 19 subjects there were anatomic abnormalities that corresponded with the location and type of clinical symptoms. Twelve subjects had changes in the disk-vertebral end plate complex and eight had a positive bone scan indicative of posterior vertebral arch stress reaction. Six out of eight boys and two out of 11 girls had stress reaction (P = 0.043). Restriction of painful activities was recommended to all subjects, restriction of activities and the use of a dynamic low-back brace for the first 3 months was recommended to patients with posterior vertebral arch stress reaction. The self-reported intensity of low-back pain (scale 0-100) among all the patients was 69 +/- 16 (mean +/- SD) at baseline and 18 +/- 21 at the 1-year follow-up (P < 0.0001). In conclusion, the reasons for prolonged back pain among young athletes are usually established by imaging studies. A knowledge of anatomic abnormalities may help in tailoring training programmes and avoiding the progression of changes during growth. Simple restriction of painful activities usually leads to good recovery.

We studied 101 patients who were operated on at Oulu University Hospital for ruptured Achilles tendon from 1987 to 1992 (inclusive), and 87 healthy control patients from among Army conscripts. The mean inequality in length of legs (ILL) was 5 +/- 4 mm. Among the 48 patients with ILL > or = 5 mm, the side affected with ruptured tendon was longer in 48% of cases and shorter in 52%. An underpronating alignment of the ankle and foot (based on beta45 measurement of the angle < or = 4 degrees) was found in 21% of patients and 5% of controls (P < 0.001). A combination of high longitudinal arch and underpronating alignment of the ankle was seen in 10% of patients and 1% of controls (P < 0.001). About 37% of the patients' feet and 29% of feet in controls were classified as having a high arch (P = 0.001). ILL or hyperpronation of the ankle seem to not be predisposing factors for ruptures of the Achilles tendon. High longitudinal arches were somewhat overrepresented, being associated with less pronation of the ankle and less varus in the forefoot than was seen in controls.

A new clinical scoring system, including subjective assessment of symptoms and evaluation of ankle range of motion and isokinetic measurement of ankle plantar flexion and dorsiflexion strengths, is presented in 101 patients (86 men, 15 women) who had repair of a closed Achilles tendon rupture. Twenty-one patients were competitive athletes and 70 were recreational athletes. Eighty-one percent of the ruptures were related to sports, and 32% occurred while playing volleyball. Twenty-six patients had previous Achilles tendon symptoms. At followup, an average of 3.1 years after repair, the overall result scores were excellent in 34 cases, good in 46, fair in 17, and poor in four. Only age was a predictor of overall results. The isokinetic strength scores were excellent or good in 72 cases, fair in 18, and poor in 11. Presence of systemic diseases, activity level, previous Achilles tendon symptoms, and later return to physical exercise were predictors of strength results. Gender, body weight, height, period between rupture and operation, surgeon, rupture site, operative method, complications, and thickness, width, and area of the Achilles tendon at followup were not related significantly to the outcome.
