Percutaneous repair of acute Achilles tendon rupture: a functional evaluation study with a minimum 10-year follow-up.

OBJECTIVE: The purpose of this study was to present the functional outcomes of percutaneous tenorrhaphy of the Achilles tendon with a minimum follow-up of 10 years. METHODS: The medical records of patients who underwent percutaneous surgery for acute unilateral Achilles tendon rupture between 2000 and 2004 were retrospectively reviewed. RESULTS: A total of 11 male patients met the inclusion criteria and were followed for a mean of 12.6 years (range: 10-13 years). The average age at the time of surgery was 39.3 years (range: 29-53 years). Patients returned to work at an average of 2.7 months (range: 1-4 months) after surgery and to normal daily activities (NDA) at an average of 4.1 months (range: 3-6 months) postoperatively. The mean strength ratio between the injured and normal sides was 90%. Compared with the contralateral normal side, the thickness of the operated tendon increased by a mean of 0.7 cm, while the circumference of the affected calf diminished by a mean of 1.1 cm. No difference in active and passive range of motion (ROM) was recorded between the affected and the contralateral normal ankle joints. Isometric plantar flexion was 87% of normal. Sensory impairment in the territory of the sural nerve was identified in 1 patient immediately after surgery. The sensory defect had completely resolved by 6 months postoperatively. CONCLUSION: Long-term outcomes of our series support the effectiveness of percutaneous tenorrhaphy in Achilles function rehabilitation of patients with acute ruptures.

Ilizarov treatment of humeral shaft nonunion in an antiepileptic drug patient with uncontrolled generalized tonic-clonic seizure activity.

Nonunion of the humeral shaft in patients with antiepileptic drug associated metabolic bone disorder constitute a challenging surgical problem difficult to treat due to seizure activity, osteoporosis, and poor stabilization options. We report a case of nonunion of the humeral shaft in an antiepileptic drug patient with uncontrolled generalized tonic-clonic seizure activity successfully treated with Ilizarov external fixator and a follow-up of 4 years.

Correction of elbow flexion contracture in late obstetric brachial plexus palsy through arthrodiatasis of the elbow (Ioannina method).

Inadequate elbow extension is a recognized sequela after obstetric brachial plexus injury because of muscle imbalance and adversely affects the ability to perform sufficiently most daily living activities. The various methods that have been used to correct this deformity do not offer a satisfactory outcome in the long term and show a tendency for gradual recurrence. We present a new technique of a closed gradual arthrodiatasis using a unilateral hinged elbow external fixator. The technique was applied in 10 patients with elbow flexion contracture as a sequela of brachial plexus birth palsy. Loss of elbow extension measured 55 degrees at average. With a mean device application of 8.8 weeks all patients gained full elbow extension. No major complications were noted. All patients were satisfied with the outcome. This novel technique (closed gradual arthrodiatasis of the elbow joint) has a definite role in the treatment of elbow flexion contracture in late cases of obstetric palsy, given the otherwise limited surgical options.

Shoulder reanimation in posttraumatic brachial plexus paralysis.

INTRODUCTION: Posttraumatic brachial plexus paralysis invariably involves the upper roots leading to paralysis of the shoulder region musculature. Early neurotisation of the suprascapular and the axillary nerve should be one of the priorities in plexus reconstruction in order to reanimate the shoulder. PATIENTS AND METHODS: From 1998 to 2007, 78 patients with posttraumatic brachial plexus palsy were operated in our department. Forty-three patients presented with supraclavicular lesions with involvement of C5 and C6 roots in all cases. Reconstruction of the shoulder function was achieved with neurotisation of the suprascapular nerve in 41 patients. Extraplexus donors were utilised in 34 patients, while intraplexus donors via nerve grafts in 7 patients. Neurotisation of the axillary nerve was performed in 25 patients, utilising intraplexus donors in 16 patients, extraplexus donors in 4, and combination of intraplexus and extraplexus donors in 5 patients. RESULTS: Suprascapular nerve neurotisation gave good or excellent results (supraspinatus>M3+ or shoulder abduction>40 degrees) in 35 patients. Intraplexus donors regained good or excellent function in 5 out of 6 patients (83%), while extraplexus neurotisations achieved good or excellent function of the supraspinatus in 30 out of 34 patients (88%). Axillary nerve neurotisation offered good or excellent results (deltoid>M3+ or shoulder abduction>60 degrees) in 14 patients (58%). Direct neurotisation of the axillary nerve via the motor branch for the long head of the triceps gave shoulder abduction of >110 degrees, as well as external rotation of >30 degrees in 3 out of 5 patients. Combined neurotisation of suprascapular and axillary nerves gave the best outcome achieving shoulder abduction of >60 degrees as well as external rotation of >30 degrees. CONCLUSIONS: Shoulder reanimation should be one of the first priorities in brachial plexus reconstruction. Early neurotisation of the suprascapular, and if possible the axillary nerve offers the best outcome.

The pelvic support osteotomy: indications and preoperative planning.

The pelvic support osteotomy is a double level femoral osteotomy with the objective of eliminating a Trendelenburg and short limb gait in young patients with severe hip joint destruction as a consequence of neonatal septic arthritis. The osteotomy has seen several changes and a brief historical overview is provided to set the evolution of the modifications of the procedure in context. We present an analysis of the preoperative assessment that will assist the surgeon to plan out the procedure. Specifically, we set out to answer the following questions: (a) Where should the first osteotomy be performed and what is the magnitude of valgus and extension correction desired at this level? (b) Where should the second osteotomy be performed and what is the magnitude of varus and derotation desired at this level?

Musculocutaneous neurotization to restore elbow flexion in brachial plexus paralysis.

Brachial plexus injuries may result in devastating paralysis, especially if they involve all the roots. The upper roots are often traumatized, and therefore elbow flexion is usually lost. The prognosis of these injuries is grave if root avulsions are present and the paralysis includes the hand as well. The current management of brachial plexus injuries should be early, aggressive microsurgical reconstruction of the plexus, combining various neurotizations with intraplexus and extraplexus nerve donors. Following this principle, we present the results of musculocutaneous neurotization in our unit, as well as a review of the literature on this subject. Our results are comparable to those reported in the literature, and indicate that the strongest function is achieved after neurotization via intraplexus donors, while some extraplexus donors (i.e., phrenic and accessory nerve) can offer equally strong elbow flexion, especially if they are used in combination. Neurotization of the musculocutaneous nerve should be one of the primary goals in the reconstruction of the injured plexus, since the return of elbow flexion is of paramount importance in daily activity. The restoration of function is ensured if the stronger and healthier motor donors are dedicated to the neurotization of the musculocutaneous nerve. Sometimes in order to match the axonal number of the target to the lower number of axons offered by the donors, two or more donor nerves may be driven to the same target, such as the musculocutaneous nerve.

Blood saving protocol in elective total knee arthroplasty.

BACKGROUND: To eliminate the need for allogeneic blood transfusion in patients undergoing elective total knee arthroplasty, we established and tried a protocol of combined methods, which is characterized by effectiveness, ease in application, and safety. It is based on perioperative administration of human recombinant erythropoietin plus iron and folic acid, mild acute normovolemic hemodilution, meticulous surgical technique, postoperative blood salvage through a closed-wound drainage system, and lower transfusion triggers. DATA SOURCES: Sixty-one patients entered the protocol, and the results were retrospectively compared with the ones obtained from 58 consecutive patients who were operated on in the past before the use of any blood saving technique. CONCLUSIONS: Only 5 patients of those who entered the protocol finally needed allogeneic blood transfusion, receiving a total number of 7 units, which is remarkable when compared with the 50 patients before the application of the protocol who required 111 units. Consequently, the utilization of allogeneic blood was reduced by 94%, a statistically quite significant result (P <0,001). We believe the protocol should be included in orthopedic surgeons' alternatives for blood saving in elective total knee arthroplasty.
