The purpose of this study was to investigate the outcome after surgical therapy of patients suffering from HO of the hip after treatment in ICU.

We retrospectively examined 39 patients with heterotopic ossification of the hip (18 bilateral and 21 unilateral). All patients have had history of ICU treatment for several reasons, such as craniocerebral injury (35 patients-90%), 2 patients with Guillain-Barre syndrome (5%), 1 patient with pulmonary druse (2.5%), and 1 patient with inflammatory bowel disease (2.5%). They all underwent surgical removal of HO and postoperative irradiation therapy. On the basis of plain radiographic findings, we evaluated the recurrent ossification after an 18-month follow-up period.

The evaluation of the average 18-months follow-up period showed relief of pain and clear improvement of range of motion in most of our patients. Specifically, improvement in the range of movement was observed in 41 hip joints (71.93%) in contrast to 16 hip joints (28.07%) that did not show any alteration post-operatively. No lesion re-occurrence was observed. There was only one complication of peroneal nerve paresis following HO excision.

The majority of our patients that were treated with surgical excision of the ectopic bone around the hip joint significantly improved their range of joint movement and were relieved from pain. Surgical excision seems to provide a superior quality of life in these patients, as they have a high risk for major complications due to their poor level of mobility.

The aim of the study to analyze the circulating white blood cells including the intensity expression of surface receptors and cytoplasmic molecules in patients underwent total hip replacement, with either aseptic or septic loosening of hip prostheses in order to identify cell-surface and cytoplasmic markers that could be indicative of early loosening. Flow cytometry was performed in whole peripheral blood samples of 20 patients with loosening (10 septic and 10 aseptic). Ten healthy individuals served a control group. The CD62L, CD18, CD11a, CD11b and CD11c expressions were evaluated. The mean fluorescence intensity (MFI) of CD 18 was decreased on all leukocytes subsets compared to control group. For patients with aseptic loosening we demonstrated an increase of MFI for CD11b in granulocytes and for CD11c in monocytes and granulocytes compared to control group. In patients with septic loosening an increase of MFI for CD 11c was observed in monocytes compared to control group. The comparison between aseptic and septic loosening showed a statistically significant lower CD18 MFI value in granulocytes for aseptic loosening. A trend towards lower MFI values of CD 62L in lymphocytes and granulocytes were observed in aseptic but not in septic loosening patients compared to control group. The present study is the first study in published literature to demonstrate cell surface and cytoplasmic markers in peripheral blood indicative of loosening of THAs by means of flow cytometry.

The objective of this study was to evaluate the functional outcome of the elbow joint in patients with heterotopic ossification of the elbow joint who underwent surgical excision of pathologic bone.

From 5/1994 to 12/2006, 24 patients (33 joints) with heterotopic ossification of the elbow joint were evaluated. All patients were attended in the Intensive Care Unit (ICU). The patient\’s age ranged from 19–48 years (mean; 32 years) The median ICU hospitalization was 3 weeks. In nine patients both elbows were affected. Unilateral involvement was equally noticed to the right (seven cases) and the left elbow (eight cases). The DASH SCORE and the range of motion were used for the evaluation of the results. All patients underwent surgical treatment in order to extract heterotopic bone and to improve the range of motion of the affected elbow joint.

Postoperatively 18 out of 33 operated elbow joints (54.54%) demonstrated improvement of the range of motion, whereas no improvement was observed in the remaining 15 elbow joints (45.45%). Higher DASH SCORE was obtained in 19 out of 24 patients (79.17%). Surgical excision of the ectopic bone around the affected elbow significantly improves the range of motion of the joint providing better use of the upper extremity and therefore a superior quality of life in these patients.

This study compares the endoscopic carpal tunnel release with the conventional open technique with respect to short and long-term improvements of functional and clinical outcomes.

We assessed 72 outpatients diagnosed with carpal tunnel syndrome. Thirty-seven patients underwent the endoscopic method according to Chow and 35 were assigned to the open method. Improvement in symptoms, severity and functionality were evaluated shortly preoperatively (at two days, one week and two weeks) and one year after using the Symptom Severity Scale, Symptom Severity Status and DASH questionnaire. Changes in clinical outcomes (grip strength, key pinch and two-point discrimination test) were evaluated one year postoperatively. Complications were also assessed.

Both groups showed similar improvement in all but one outcome one year after the release; increase in grip strength was significantly higher for the endoscopic group. The endoscopic method was also associated with a significantly faster short-term improvement. Separate analysis of the questionnaire components referring to pain reveals that the delay of improvement in the open group is due to the persistence of pain for a longer period. Paresthesias and numbness decrease shortly after the operation with comparable rates for both groups.

The purpose of this study is to evaluate the long-term results of the surgical treatment of cubital tunnel syndrome by comparing the in-situ decompression and release of the ulnar nerve with or without partial medial epicondylectomy and the anterior transposition and release respectively.

Material and Method: From 1991 since 2008, 119 patients, (81 men and 38 women) with an average age of 51(13–72 years) years were treated surgically for ulnar nerve compression at the elbow. The average duration of symptoms before surgery was 15 months (2–48 months). Preoperatively 2 patients were grade I, 52 patients were grade IIA, 31 patients were IIB and 34 were grade III according to the modified McGowan score. We performed in-situ decompression of the ulnar nerve in 35 patients, release with partial medial epicon-dylectomy in 44 patients and release with anterior transposition of the nerve in 40 patients.

17 patients were lost to follow-up. 108 patients were clinically assessed. Comparing the results among different surgical procedures, an improvement of at least one McGowan grade was obtained in 26 of 30 patients treated with simple decompression, in 29 of 35 patients treated with release and anterior transposition of the nerve and in 38 of 43 patients treated with release and medial epicondylectomy.

The results of this study show that the possibility for complete recovery is inversely related to the initial neuropathy grade. Partial medial epicondylectomy is a valuable surgical procedure for treating grade I to IIB ulnar neuropathy because is an anatomic method with minimal nerve manipulation preserving regional blood supply.

Total hip arthroplasty (THA) in neglected congenital dislocation of the hip (CDH) constitutes a challenging procedure, with surgical difficulties and complications. The purpose of this study was to analyse the complications of THAs in CDH.

Between June 1983 and September 2002, 418 THAs-were performed in 356 patients with CDH, with a mean follow-up 108 (7–237)months. The mean age at surgery was 53.3 (24–79) years with 325 females and31 males. 83 patients had CDH in high position. 307 arthroplasties were cementless, 39 cemented and 72 hybrids. 40 stems were custom made. The cup always was positioned at the true acetabulum. 24 shortening osteotomies of the femur, 8 corrective supracondylar and 6 trochanteric osteotomies were performed.

Preoperatively the average Merle d’Aubigne-Postel hip score was 1.1 for pain, 4.8 for range of motion and 3.1 for walking ability. Postoperatively the average hip score was 5.2, 4.7 and 5.3 respectively. The average length discrepancy was 8 cm (3–12) preoperatively and 1.5 cm remained in 8 patients. Complications included 7 intraoperative fractures of the femur, 12 dislocations, 4 peroneal nerve palsies that recovered, 25heterotopic ossifications, 7 deep vein thromboses, 3 pulmonary embolisms, early mechanical loosening in 4 cemented and 10 cementless cups and 3infections.

Complications were diminished dramatically last years due to improved surgical technique, new available implants and preoperative evaluation of the hip with CT and CAD-CAM-CAE study that allowed better surgical planning with trial stem implantation from a series of stem designs and custom made femoral components manufacturing

We present our experience from use of acetabular reinforcement rings in revision total hip arthroplasty when bone defects are present. From 1987 to 2000, acetabular reinforcement rings were utilized in 59 revisions, in 52 patients with a mean age of 60 years (31–81). In 48 hips, Ganz rings were used and in 11 hips, Burch-Sch-neider rings. For the existing defects of the acetabulum, morsellized bone allograft was used. The patients were evaluated clinically with the modified Merle d’ Aubigne-Postel scale and radiologically with the criteria of Gill-Sledge-Muller. Acetabular reconstruction was successful in 51 of 59 hips (86.5%) after a mean follow-up period of 7 years (2–15). One of the 11 Burch-Schneider rings failed (9.1%) and 7 of the 48 Ganz, raising the failure rate of this ring up to 14.6%. Complications included dislocation in 5 cases, deep vein thrombosis in 2, superficial infection in 1 and pubis rami fracture in 2 cases.

Reinforcement rings in our opinion could be of valuable help in reconstruction of the bone deficient acetabulum. Although in this study, it is not possible for these two rings to be directly compared, Burch-Schneider one appears to have a more clear role and lower failure rate. However, in order to evaluate in a more reliable way the true fate of the acetabular reinforcement rings, especially in the presence of the limited role of biological fixation, longer follow-up time is needed.

Aim: Adequate length is an important prerequisite for a functional digit. Over the last 20 years small external fixators have been developed allowing the principles of distraction osteogenesis to be applied to the small bones of the hand. We present our experience in digital lengthening with the contemporary designs of external fixators. Methods: From 1998 to 2001, 20 patients (26 rays) were treated with metacarpal or phalangeal lengthening through distraction osteogenesis using a monolateral frame with two half-pins on each site of the osteotomy. The mean age of the patients was 21 years (6–48) and indications included traumatic amputation in 13 and congenital amputation (transverse deficiency, brachydactyly, constriction band syndrome) in 7. The mean distraction period was 3 weeks and the mean consolidation period 7 weeks. No protective splinting or additional bone grafting was necessary. Results: The distraction callus consolidated in all patients. The mean total length gained was 17,5 mm (68% of the original length). The mean treatment time was 2,8 days for every mm of length gained. One patient suffered angulation at the distraction site and the fixator had to be revised. No infection, fracture or half pin loosening were observed. Conclusions: Callotasis is a reliable technique for digital ray lengthening. Meticulous surgical technique and close observation of the patient during the distraction phase are necessary in order to avoid complications. Over 2 cm of lengthening can be achieved without bone grafting

Aim: Although primary ßexor tendon repair in children yields satisfactory results, some children end up with poor function because of delay in diagnosis, technical difþculties and the inability to follow a structured rehabilitation program. The aim of this study is to evaluate the functional outcome after two stage reconstruction with the modiþed Paneva technique (which includes creating a loop between the proximal stumps of Flexor Digitorum Profundus and Superþcialis in the þrst stage and reßecting the latter as a Ç pedicled È graft through the pseudosheath created around the silicone rod, in the second stage) in children. Methods: Nine patients (9 digits) with a mean age of 8,2 years (range 3 Ð15) were treated for zone II lesions. Their pre-operative status in the Boyes and Hunter scale was grade two in 3, grade three in 3, grade four in 1 and grade þve in 2 patients. Results: After a mean of 42 months of follow-up (minimum 12 months), according to the Buck-Gramco scale there were 4 excellent, 4 good and 1 poor result and according to the revised Strickland scale 3 excellent, 5 good and 1 poor. Children over the age of 10 had slightly improved Total Active Motion (mean +350) compared to younger ones. No signiþcant length discrepancies were noted. Two postoperative infections were treated and one graft-related re-operation was necessary. Conclusions: Staged ßexor tendon reconstruction in children is technically feasible and efþcient. Delaying such a reconstruction in younger children does not seem justi-þed.

Aims: In the present study we reviewed 105 patients who had had Galeazzi fractures with particular emphasis on classiþcation (þve types according to the fracture patterns), treatment, and þnal results. Methods: One hundred and þve cases (75 males and 30 females) were included in this study. Most of the fractures (70 cases) occurred in the distal third of radial shaft (Type I). Seventeen fractures were in the middle third (Type II), and 11 fractures were in the proximal third of the shaft of the radius (Type III). In four cases disruption of the distal radio-ulnar joint associated with fractures of both bones (Type IV). Finally three cases considered as Galeazzi-equivalent lesions (Type V). Results: The mean follow-up time was 7 years. The overall results were good in 81% of the patients, fair in 14% and poor in the 5% of the patients. Union achieved in 102 cases and non union in three cases (two had had primary conservative treatment and one case was treated surgically). Supination ranged from 40 to 90 degrees (average 77.5 degrees), and pronation from 50 to 90 degrees (average 81.6 degrees). Conclusions: The Galeazzi fracture is uncommon injury with an incidence varying from 3% to 6% of all forearm fractures. The key to satisfactory results in the treatment of the Galeazzi lesion is anatomic restoration of the length of the radius, with application of rigid internal þxation to maintain the reduction. Although most of the reports do not recommend exposing the distal radioulnar joint, we suggest that once the anatomic reduction is secured, anteroposterior and true lateral x-rays planes to control the distal radioulnar joint.

Aim: To study the carpal geometry in patients with symptomatic scaphoid non-union without arthritis or with early arthritic changes. Method: The preoperative x-rays of 58 patients were retrospectively reviewed and x-rays of 35 of those fulfilling strict criteria for true projections were digitized and measured using CAD methodology. Patients’ mean age was 31,3 years and mean time from fracture 50,4 months. The measured variables concerned the carpal height, possible displacement of the carpal bones and carpal instability. The Herbert and Fisher classification was used and two subgroups concerning the absence (14) or presence (21) of early arthritic changes were created. Results: 62,5% of the patients (including patients without radiologicaly obvious arthritis) were presented with increased radial height and radial inclination, 28% with an affected carpal height, 17% with ulnar translocation of the wrist and up to 48% (varying according to the method of measurement) with a DISI pattern of instability. No statistically significant differences could be established between the morphological groups or between the two subgroups concerning early arthritis. Conclusions: Carpal geometry in scaphoid non-union although altered does not seem to change significantly with the appearance of early arthritis and thus treating non-union with early arthritis with osteosynthesis and bone grafting seems justified. In view of our findings it seems appropriate to supplement this procedure with distal radial osteotomy or with temporary lunate stabilization in selected patients.

This study of surgically treated distal tibia fractures was undertaken to compare the internal fixation with the two external fixation methods.

There were 40 patients with 41 pilon fractures. The mean age was 51.2 years (18–76). 17 of the 40 patients-14 from vehicular accident, 3 from fall – were treated with an ankle-spanning half-pin external fixator (11C, 6B, 11 Weber B- 5 C, 1IIIa, 5I, 6II). 11 patients-10 from vehicular accident, 1 from fall- were treated with a single-ring hybrid ankle-spanning external fixator (9C, 2 B, 6 Weber B-4 C, 5I, 2II). 13 patients-10 from vehicular accident and 1 from fall- were treated with an epiunion plate (1A, 8B, 4C, 5I, 3II, 10 Weber B- 1C). The mean follow-up was 4.2years (1–8). Fracture union was defined as having three cortices bridging on the plain radiographs for a patient who was able to bear full weight. Non union was defined as a fracture that did not heal within a year.

Fracture union was achieved for 36 of the 41 fractures. Three patients with external fixator, one with hybrid and one with plate had septic pseudarthrosis. Fractures in the external fixator and hybrid groups had a tendency to lose the reduction. Four patients with external fixator had delayed union and have lost range of motion in the ankle. Five patients in the external fixator group are candidates for ankle arthrodesis due to arthritis.

The ORIF and hybrid fixator were equally efficacious in achieving bony union and not to lose range of motion in the ankle. Fractures in the external fixator with the ankle – spanning had higher rate of delayed union and loss of motion in ankle. The choice of the external fixator is dependent on the surgeon and the type of the fracture. However the patient must be followed up for the stability of the system.

Purpose: We perform the results of the operative treatment of cubital tunnel syndrome, and a retrospective review of the surgical options of in situ decompression of the ulnar nerve, release and anterior transposition of the ulnar nerve and ulnar nerve release and partial medial epicondylectomy.

Material and Methods: Seventy four patients, 52 male and 22 female, (78 elbows), were treated surgically from October 1991 to November 2002.The mean age was 51 years (range, 13 to 72 years). Sixty four patients were assessed postoperatively with mean follow-up 80 months (range 6–139 months). Twenty patients underwent in situ decompression of the ulnar nerve, 34 patients release and anterior transposition and 14 ulnar nerve release and partial medial epicondylectomy. According to the McGowing evaluation system were classified in Grade I, none, Grade II, 38 patients and Grade III 26 patients. The 64 patients were evaluated clinically and 16 of them by EMG studies postoperatively.

Results: Sixty one patients had had subjective improvment of their symptoms. Thirty seven patients (57.8%) excellent, 21 patients (32.8%) good, 3 patients (4.6%) fair and 3 patients (4.6%) poor results. (Wilson & Krout). The comperative results among the surgical options of our study showed improvement in the subjective outcome of 32 out of 34 patients who had release and anterior transposition of the ulnar nerve. From the 20 patient who had in situ decompression of the ulnar nerve, 19 had improvement and from the rest 14 patients who had had ulnar nerve release and partial medial epicondylectomy, they all had improvement.

Conclusions: The results for the patients in this study who had ulnar nerve release and partial medial epicondylectomy, are comparable in good results with other operative treatment options for the cubital tunnel syndrome.

Purpose: Vascular injuries occur in approximately 3% of all patients with major civilian trauma and peripheral vascular injuries account for 80% of all cases of vascular trauma. Upper extremity arterial injuries represents about 30% of all cases arterial trauma. The present study was designed to document and analyze the respective role of arterial damage and associated injuries on functional outcomes after upper extremity arterial trauma.

Material and Methods: Excluding the arterial injuries resulting in immediate amputation there were 57 patients who sustained arterial trauma of the upper extremity. Their mean age was 33 years (range 4–68 years), and 40 were males and 19 were females. The most frequently injured vessel was the ulnar artery (42%) followed by the brachial artery (29.8%), radial artery (26.3%) and axillary artery (1.7%). Concomitant fractures or nerve injuries were present in 54% and 45% respectively.

Results: An average of 5.6 hours elapsed between the time of injury and the time of vessel reconstruction. The most common method of surgical management was end to end anastomosis. Twenty one autogenous vein grafts were employed. Primary nerve repair was carried out in 29 patients and in another 18 secondary repair was performed. None of patients had any residual compromise from the arterial injury.

Discussion: Vascular injuries are potentially limb threatening. Improvements in the technical ability to revascularize injured extremities and advances in microsurgery, resulting in the low present day limb loss rate associated with attempted vascular repairs. Associated injuries, rather than vascular injuries, cause long-term disability in the trauma of the upper extremity. Persistent nerve deficits, joint contractures and pain are principal reasons for functional impairment

Purpose: Although transient osteoporosis of the hip was initially described in pregnant women, now most frequently identified in middle-age and older men. Has also been reported to occur in either hip and in both successively. This condition is referred as migratory transient osteoporosis of the hip. In this study the authors describe five cases of migratory hip osteoporosis and the differential diagnosis with osteonecrosis is also discussed.

Material and Methods: Thirty-four patients with transient osteoporosis were presented. Of the 34 patients five had a similar episode of severe pain in the contralateral hip 14 months mean time later. Early bone scans and MRI of the hips had been carried out in all of the patients. After the evaluation of these findings and thorough exclusion of other conditions diagnosis of migratory transient osteoporosis was demonstrated, and confirmed by the natural course of the disease.

Results: All cases were treated with nonsteroidal anti-inflammatory medications and protected weight-bearing. The course of the disease has not been appreciably altered by medical treatment, and the mean time interval from the onset of symptoms to clinical recovery was 4.6 months (range 3 to 6 months). Imaging findings on MR confirmed the diagnosis during both episodes and paralleled the reduction of pain.

Conclusions: Migratory transient osteoporosis of the hip is a rare self-limited condition of uncertain etiology and pathogenesis, which “migrate” from one hip to the other. Magnetic resonance imaging is highly sensitive in the early detection of this condition and moreover is helpful in the exclusion of other entities. Although the diagnosis is one of exclusion, it must be considered and contrasted with hip osteonecrosis.

Purpose: The first 50 free flap operations performed at our clinic by the same surgical team were reviewed and assessed as to the cause and location of the defects, donor sites, complications and results. An attempt was then made to determine what could be learned from this experience.

Material and Methods: There were 46 males and 4 females who underwent free flap operations (mean age, 28.5 years; range 6 to 56 years). The lower extremity was the most frequent site of defect (72.5%). The next most frequent sites were the arm and the hand (27.5%). Trauma was by far the most common cause. Latissimus dorsi and forearm flap were the most useful flaps. Fractures in the wound were present in 26 patients.

Results: The fate of the flaps has been analysed. In two latissimus dorsi flap emergency re-exploration was performed and were successfully managed. Two flaps, underwent necrosis, due to thrombosis at the site of arterial anastomosis. Two flaps were lost due to inappropriate blood flow of the recipient vessels. Other complications included pressure ulcer, infection, and hematoma. The overall survival rate of the 50 cases was 92%.

Discussion: Limb reconstructive surgery has significantly improved and expanded with the use of microsurgical techniques. Evaluation of the recipient vessels is always the first priority. The choice of the flap, specially regarding the length and size of the pedicle is also very crucial in order to achieve good results. In addition important factors seemed to be: improvement in techique of micro-vascular anastomosis, diseased vessels, vascular spasm, hypotension, postoperative edema, and hematoma. We believe that an “orthoplastic” approach in covering soft tissue defects is beneficial.

Natural history studies of scaphoid non-unions focus on symptomatic non-unions. As a consequence, neither the real incidence nor the long-term sequels of asymptomatic scaphoid pseudarthrosis have been sufficiently studied.

Three adult patients (38, 40 and 79 years of age) with long-standing asymptomatic scaphoid non-union are presented. The lesions were identified in radiographs taken in the accident and emergency department after new injuries. All patients could recall the initial fracture, which occurred 17.5, 20 and 40 years respectively before the index examination.

Although all the patients were heavy manual workers and in two the non-union occurred in their dominant upper extremity, none could recall pain during activities. Radiographic evidence of carpal malalignment and/or arthritis was noted in all patients. At the 3-month follow-up after the new injury all patients remained asymptomatic with only mild limitations in the range of motion.

With evolving trends of ORIF in unstable scaphoid fractures, there is need for larger-scale natural history studies that include asymptomatic scaphoid non-unions. Such lesions are currently poorly understood and their treatment (if one is needed) remains unclear.

Aim: The primary purpose of this study was to establish data concerning normal hand grip strength in the population of N.W Greece.

Material and Methods: The Jamar dynamometer was used to measure grip strength. A sample of 115 males and 117 females, with no extremity disability or injury, aged 21 to 58 years, from the Ioannina area was tested. The dynamometer was tested in a standing position, with shoulder adducted and neutrally rotated, elbow flexed at 90 degrees and forearm and wrist in neutral position. Each participant was asked to grip first with the right and then with the left hand three consecutive times. The highest grip strength for each hand was used for analysis. All complementary factors such as age, sex, height, weight, hand dominance for writing and exercise and living habits were recorded.

Results: Grip strength diminishes curvilinearly with age, and men are consistently stronger than women. Mean maximum grip for women was 67 pounds and for men was 123 pounds. The hand dominance does not significantly affect hand strength scores. The mean grip strength of the left hand was about 90% that of the right hand. In left-handed participants, mean grip was the same for both hands. The results from this study showed that sex is the most important determinant of hand grip strength.

Conclusions: The random sample, the high participation rate of this study and the number of the factors that affect the hand strength give the highest validity in this study. These data suggest a basis to help hand surgeons as a guide regarding grip strength in the treatment of upper extremity pathologic conditions and postoperative evaluation.

Although primary flexor tendon repair in children yields satisfactory results, some children end up with poor function because of delay in diagnosis, technical difficulties and the inability to follow a structured rehabilitation program. The aim of this study is to evaluate the functional outcome after two stage reconstruction with the modified Paneva technique (which includes creating a loop between the proximal stumps of Flexor Digitorum Profundus and Superficialis in the first stage and reflecting the latter as a “pedicled” graft through the pseudosheath created around the silicone rod, in the second stage) in children.

Nine patients (nine digits) with a mean age of 8.2 year (range 3–15) were treated for zone II lesions. Their pre- operative status in the Boyes and Hunter scale was grade 2 in three, grade 3 in three, grade 4 in one and grade 5 in two patients.

After a mean of 42 months of follow-up (minimum 12 months), according to the Buck-Gramco scale there were four excellent, four good and one poor result and according to the revised Strickland scale three excellent, five good and one poor. Children over the age of 10 had slightly improved Total Active Motion (mean +35°) compared to younger patients. No significant length discrepancies were noted. Two postoperative infections were treated and one graft-related re-operation was necessary.

Staged flexor tendon reconstruction in children is technically feasible and efficient. Delaying such a reconstruction in younger children does not seem justified.
