Introduction

Distraction histogenesis is utilised for cosmetic reasons in patients with constitutional short stature, achondroplasias, or height dysphoria. One of the considerations of patients and surgeons alike, is the preservation of aesthetically acceptable body proportions after the lengthening i.e which segment of the lower limb to lengthen and by how much, in order to preserve the patient's proportions within -or as close as possible to- the normal range of human body proportions. Sound anthropometric data on the normal range of the human body proportions is currently lacking. The aim of this study is to calculate the normal range of the ratio between the lengths of the lower limb, upper limb, femur, tibia, stature and trunk.

Methods

Data form standardized measurements of the lengths of the tibia, femur, arm, stature, lower limb, upper limb was obtained from a sample population of 6068 healthy men and women servicing in the US Army. The mean, median, range and standard deviation were calculated for the following ratios of lengths: whole lower limb/leg, Stature/leg, Whole lower limb/thigh, Stature/thigh, Siting height/whole lower limb, Stature/Whole lower limb, Arm Span/Stature, Whole upper limb/Whole lower limb.

Ultrasound treatment can be used as an alternative to surgical methods for treating non-union or to enhance healing in a delayed union. This study presents our short-term results of using low intensity pulse ultrasound stimulation in long bone non-union. 18 patients with surgically treated long bone non-union were treated using the Exogen® ultrasound stimulator (Smith & Nephew Inc., UK). The average age of patients was 48 years (20–73 yrs). There were 8 femur fractures, 9 tibial fractures and 1 knee arthrodesis. 5 of these patients had infected non-union. The average follow up after initiation of treatment was 4 months (range 2–8 months). They received 20 minutes stimulation daily at the fracture site with regular follow up in clinic. We reviewed their serial radiographs and clinical progress. The mean interval to initiation of the ultrasound treatment was 7.9 months (2–27 months). Complete bony union was obtained in 6 of the 18 cases (33%) within 4 months of initiation of treatment. In 7 of 18 cases (38%) there was good evidence of progress towards bony union, while in 4/18(22%) patients there was no progress towards union at average of 4 months (range 2–8 months). There were no complications noted with this treatment. Most non-unions are treated by surgical revision, with consolidation rates ranging from 85 to 100% according to previous studies. Our study suggested 72% patients showing progress towards union with 33% achieving bony consolidation at 4 months. Patients with infected non-union also benefitted from this treatment. In summary ultrasound treatment can be a viable option to treat long bone non-unions, which may avoid the morbidity and complications associated with surgery.

Background

Chronic osteomyelitis with intramedullary sequestrum resulting in persistent infection is a challenging orthopaedic problem that often involves multiple surgical operations and unfortunately has a significant recurrence rate. Reasons for this may include difficulty in eradicating all intramedullary microsequestra making subsequent prolonged antibiotic therapy less effective. Use of the Reamer-Irrigator-Aspirator (RIA) has many advantages for management of intramedullary infections in chronic osteomyelitis. The RIA technique allows irrigation of sterile large quantities of saline with simultaneous bony debridement with very sharp reamers that are specially designed to allow simultaneous fluid aspiration.

Purpose

We will illustrate the pearls and pitfalls associated with the RIA technique, based on our experience so far.

Previous reports have shown the efficacy of muscle interposition grafts in treating recalcitrant infection in the presence of hip arthroplasty. We report our experience with a two stage debridement and rectus femoris pedicled interposition graft technique in chronic severe native hip infection with a persistent draining sinus.

During the last 16 months, three paraplegic patients presented with persistently draining sinuses and chronic osteomyelitis of the pelvis, acetabulum and proximal femur, in a total of four hips. The mean patient age was 49 years (range, 40 to 59 years). In all patients there had been previous attempts to control the infection with wound debridement and long-term antibiotics.

A two-stage operative treatment was used in all patients. The first stage comprised wound debridement, washout, gentamycin-bead application and temporary vacuum assisted wound coverage.

At the second stage, approximately ten days later, through a standard anterior midline incision, the rectus femoris muscle was elevated on its pedicle, rolled, transposed into the acetabulum and sutured to the transverse acetabular ligament. At the second stage, all patients had local administration of antibiotics with genetamycin impregnated absorbable collagen fleece and all wounds were closed by delayed primary closure with a negative pressure dressing placed over the closed wound. All patients were commenced on a 6 week course of intravenous antibiotics, according to sensitivities.

No loss of flap occurred in any of the patients. One wound had partial dehiscence and required a split skin graft. At the final follow-up examination all the wounds were healed and there was no recurrence of draining sinuses, pressure sores or systemic sepsis.

The two stage technique with a pedicled rectus femoris interposition graft may be a useful technique for the treatment of complex chronic persistent osteomyelitis of the pelvis, acetabulum and proximal femur, with the primary aim of stopping the discharging sinus.

Advance medial pivot total knee replacement has been designed to reflect contemporary data regarding knee kinematics. We report the clinical outcome of 284 replacements in 225 consecutive patients. All patients were prospectively followed for a mean of 7.6 years (5 to 9) using validated rating systems, both objective and subjective.

All patients showed a statistically significant improvement (p~0.01) on the Knee Society clinical rating system, WOMAC questionnaire, SF-12 questionnaire, and Oxford knee score. The majority of patients (92%) were able to perform age appropriate activities with a mean knee flexion of 117° (85 to 135). Survival analysis showed a cumulative success rate of 99.1% (95% CI, 86.6 to 100) at five years and 97.5% (95% CI, 65.6 to 100) at seven years. Two (0.7%) replacements were revised due to aseptic loosening, one (0.35%) due to infection and one (0.35%) due to a traumatic dislocation. In only two (0.7%) replacements, progressive radiological lucent lines (combined with beta angle of 85°) were observed

In order to evaluate the short- and long-term clinical and radiological results of MIS in TKA, a prospective randomized trial was designed in our department. All patients admitted to the department under the care of one surgeon specializing in Joint Replacement surgery were assigned to participate in the study, signed a concern form, and randomly allocated into two groups. For patients of group A, a TKA was performed using the mini mid-vastus approach; for patients of group B the surgery was performed using a conventional medial parapatellar incision. The Genesis II prosthesis and MIS instrumentation were used for all patients.

Pre and postoperative clinical and radiological data were collected for all patients at regular time intervals (pre, 1st d, 3rd d, 6th d, 3rd w, 6th w, 3rd m, 6th m, 9th m, 1st y, and every year thereafter). Early postoperative pain was also evaluated using a VAS scale and the ability of early SLR was also recorded.

Until now 80 patients (40 MIS, 40 Controls) have entered the study with a follow-up of more than 6 months. In 5 patients (12.5%) of group A the MIS surgery was abandoned in favor of conventional surgery due to technical problems.

Patients in MIS group A had knees with greater range of motion at 3 w, 6 w and 3 months, better function at 3 and 6 months, and less blood loss. In contrast, the same patients experienced greater pain during the first 3 postoperative days. Surgery lasted 16 minutes more on average for the MIS group A. On radiological evaluation technical errors were observed in 5 patients of MIS group A.

Purpose of this study is to examine the role of MRI arthrography in chronic cases of shoulder instability. Shoulder arthroscopy was elected as standard record of diagnosis.

Patients & Method: We evaluated 155 shoulder arthroscopies in 153 cases of recurrent shoulder instability from Sept 99 to Feb 03. Each patient suffered at least 2 true dislocations. Pre-op, we performed MRI scan in 82 of them while, 15 other cases were evaluated more invasively with MRI arthrography, with anterior portal infusion technique. Results were analyzed blindly from 2 radiologists with particular experience in MRI musculoskeletal cases and were compared to arthroscopic findings.

Results: Bankart lesion was diagnosed in all cases with MRI arthrography (sensitivity 100%), SLAP lesion had sensitivity 50% and specificity 100% while, rotator cuff pathology was diagnosed in 6 out of 7 cases. There were also 4 false positive cases in rotator cuff pathology. Sensitivity for superior and inferior gleno-humeral ligament was 100% and 94% respectively, without any true negative findings in both of them. Sensitivity and specificity for middle glenohumeral ligament was 89% and 60% respectively. In cases where we recognized loose anterior capsule pathology during arthroscopy, the radiologists were not able to detect these lesions from a functional aspect. Despite the fact, that all Hill Sachs lesions were identified through MRI arthrography it was also possible to be detected functionally.

Conclusions; MRI arthrography is a reliable tool in recurrent shoulder instability while is an invasive method because of the infusion material. Anterior glenohumeral instability is not always a Bankart lesion but gleno-humeral ligaments pathology too that, can easily be detected during arthroscopy which may be the therapeutic solution at the same time.

Aim: To describe the technique and the mid term results of anterior shoulder instability arthroscopic reconstruction.

Patients-methods: Between March and December 2000 29 patients-28 males with ages ranging between 19–29 years (mean age 23 y.) and 1 female 24 years old-underwent arthroroscopic stabilization of anterior shoulder instability. During the procedure the anterior-inferior part of the labrum was reattached to the glenoid using bioabsorbable and metallic suture anchors. In selected patients in which capsule plication after anchors’ insertion was insufficient additional capsular shrikange or/and rotators’ interval closure was also performed.

Results: Postoperatively patient evaluation took place using Rowe-Zarins scale. According to this score 22 patients (75,9%) had excellent or very good outcome. Three (3) patients (10,35%) were lost during follow up while 1 (3,45%) died. From the remaining 25 patients 2 had recurrence of the instability (6.9%) and in 1 patient (3,45%) a stiff shoulder was noticed and arthroscopically resolved. Finally a disengaged metallic suture anchor was noticed incidentally during routine radiographic examination in one patient (3,45%).The anchor was successfully removed under arthroscopic visualization without compromising the final outcome.

Conclusions: Arthroscopic reconstruction of anterior shoulder instability when precisely performed after correct patient selection is an effective technique achieving results comparable to those of traditional open procedures.

Aim: The description of technique and early results of arthroscopic rotator cuff tears (RCT) reconstruction.

Patients-Methods: Âetween 01/2001 and 02/2003 26 patients, ranging in age from 33–82 (mean age 61,5 y.) – 17 males, 9 females – with RCT underwent arthroscopic reconstruction including debridement, sub-acromial decompression and mobilization of the rotator cuff. The RCT was then repaired with the arm in neutral position using “side to side” suturing technique and rotator cuff anchors when needed. Postoperatively, rehabilitation program included initially passive, active kinisiotherapy while exercises under resistance were finally performed..

Results: All patients were evaluated using ASES and UCLA scores pre-and postoperatively. Pain relief postoperatively was noticed in almost all reconstructed patients. In order to indentify functional improvement range of motion and strength were seperately evaluated. Range of motion just as pain remission was notably improved in almost all patients while strength ameliorate most in patients with complete restoration of rotator cuff tear. The interval between reconstruction and full patients’ recovery ranged between 3 months – pat. < 60 years – to 6–8 months – pat. > 60 years.

Conclusions: Arthroscopic RCT reconstruction although a demanding technique achieves satisfactory early results—mainly regarding pain relief and range of motion improvement- comparable to those of open repair reducing also postoperative morbidity.

Aim: Traumatic shoulder dislocation in patients older than 50 years is an unusual injury with specific anatomic lesions and different treatment considerations than these encountered in younger patients. We present our experience in treating such kind of injuries.

Patients-methods: Between January December 2002 9 patients-4 males, 5 females – with ages ranging between 50–72 years (mean age 64 y.), have been treated in our department suffering from first traumatic shoulder dislocation. Rehabilitation program and overall recovery progress was observed in an outpatient basis while postoperative outcome was evaluated using ASES and UCLA rating scores.

Results: In 4 patients rotator cuff tear was found and reconstructed by suturing the lesion. One (1) of these patients, who had a coexisted bony Bankart lesion, presented 1 ½ month postoperative with recurrence of dislocation. Bony Bankart lesion prevented reduction in 2 patients and was reconstructed using open stabilization in one and arthroscopic to the other. HAGL lesion was detected in another patient and treated with open reduction and shoulder stabilization. Finally 2 patients with shoulder dislocation and coexisted greater tuberosity fracture were treated with closed reduction.

Conclusions: Ttraumatic shoulder dislocation in patients older than 50 years consists a distinct entity which if inadequately treated leaves the shoulder with severe functional impairment. Recurrent shoulder dislocation is an unusual complication in such patients but on the other hand rotator cuff tears and glenoid bony lesions are frequently encountered necessitating treatment. Postoperative patients should be examined in small intervals with a high degree of suspicion for the above mentioned coexisted lesions.
