Volkmann's ischaemic contracture of the upper extremity - raising a red flag in the setting of developing countries.

INTRODUCTION: Volkmann's ischaemic contracture (VIC) is a disabling condition resulting from tissue necrosis due to impaired vascular supply to the limb. Over the years VIC has become rare in developed countries with many different aetiologies described. It was alarming to have high incidence of established VIC in our practice in Nepal. A detailed analysis was conducted to accurately describe this issue. METHODS: We collected 47 cases of VIC over six years and noted the age, sex, district of origin and cause of VIC, duration of injury to presentation, and the grade of VIC. Then we compared these characteristics of VIC of each Nepal province and created a map to show the problematic regions. RESULTS: Out of 47 patients, 46 could have been prevented by an early treatment. The most common cause was a tight cast in 25 patients (53.19%), followed by unintentionally self-caused VIC by applying tight bandages in 21 patients (44.68%). Most cases came from province 6 (29.78%). Our group included three mild (6.4%), 35 moderate (74.5%) and nine severe (19.1%) cases of VIC. Only 14 cases (29.78%) had a timely fasciotomy in the past. CONCLUSION: VIC is an irreversible complication of the compartment syndrome which is an easily preventable condition in the setting of developing countries. Our focus should, therefore, aim at preventing such disastrous conditions as 97.87% of cases we encountered could have been avoided by proper primary care. In the case of Nepal most cases came from province 6 and province 3.

Congenital Flexor Contracture of Ulnar Digits Masquerading as Volkmann Ischemic Contracture.

ABSTRACT: Congenital flexion contracture of ulnar digits is a rare entity with few cases reported in medical literature. This condition is often misdiagnosed as Volkmann ischemic contracture as both have similar presentation. The patient history, physical examination, radiological investigation, and intra-operative findings can differentiate these 2 conditions clearly. A 14-year-old female presented to a tertiary care hospital with flexion deformity of the left long, ring, and little fingers without neurological deficit since she was 3 years old. Patient had decreased handspan with difficulty in grasping daily life objects. Finger flexion deformity was also not aesthetically acceptable due to social stigma. Patient finger contracture was managed with flexor pronator slide (Max-Page) operation. The muscle slide operation was done using concealed medial incision. Aesthetic and functional correction was achieved with no recurrence at subsequent follow-ups.

Free vascularized fibula leads to hallux toe flexion deformity due to ischemic muscle contracture of flexor hallucis longus.

BACKGROUND: This study aimed to investigate the incidence of toe flexion deformity after fibular free flap transplantation and to analyze the etiology of the deformity. METHODS: Fifty patients underwent vascularized fibular free flap transplantation were retrospectively included. Statistical analysis examined correlations between deformity occurrence and resected fibula length and residual distal fibula length using the χ2 test. Doppler ultrasound and anatomical evaluations were conducted. RESULTS: Flexion deformity of the first toe was observed in all patients (100%), exacerbated by ankle dorsiflexion. χ2 test revealed no significant correlation between fibula length, distal residual fibula length, and flexion deformity. Doppler ultrasound revealed elevated echoes and blurred textures in the flexor hallucis longus post-fibular transplantation, while anatomical evaluation confirmed the peroneal artery as its primary nutrient supplier. CONCLUSION: This study reports a 100% incidence of toe flexion deformity post-transplantation. The deformity correlated strongly with ischemic contracture of the flexor hallucis longus.

Functioning Free Muscle Transplantation to Restore Finger Movement for Sequalae of Volkmann Ischemic Contracture.

Volkmann ischemic contracture (VIC) is a devastating condition that results from neglected compartment syndrome, which leads to prolonged ischemia, irreversible tissue necrosis, and various degrees of muscle and nerve damage, causing serious motor and sensory functional implications for the limb and a spectrum of diseases associated with worsening deformities. A thorough understanding of the anatomy and VIC pathophysiology is needed to plan an appropriate strategy. Functioning free muscle transplantation (FFMT) can restore finger movement in a paralyzed limb but requires a three-staged approach to maximize the benefits of FFMT, leading to meaningful finger extrinsic function.

Successful treatment of early ischemic contracture in the upper arm caused by traumatic haematoma through surgical muscle release and continuous passive motion: Case report.

BACKGROUND: Compartment syndrome is a condition that occurs when there is an increase in pressure within a muscle compartment, leading to a decrease in blood flow to the muscles and nerves within that compartment. If left untreated, this can lead to ischemic contracture, which is a late sequelae of compartment syndrome that occurs when there is sustained ischemic damage to the muscles. Timely diagnosis and treatment are critical in reducing the extent of permanent changes within muscle and nerve tissue. No previously published studies have reported on the treatment of early ischemic contracture resulting from traumatic haematoma in the upper arm. We present an exceptional case involving a 17-year-old male who developed this condition following a collision during a basketball game, resulting in a haematoma with severe pain, tightness and restricted range of motion in the affected arm. He was treated through surgical intervention involving surgical muscle release, haematoma evacuation and continuous passive motion (CPM) postoperatively to restore the range of motion and improve overall function with complete recovery at the 27-month follow-up.

[Diagnosis and treatment of finger flexion contracture caused by forearm flexor disease].

Objective: To summarize the clinical characteristics, differential diagnosis, and treatment methods of finger flexion contracture caused by three kinds of forearm flexor diseases. Methods: Between December 2008 and August 2021, 17 patients with finger flexion contracture were treated, including 8 males and 9 females, aged 5-42 years, with a median of 16 years. The disease duration ranged from 1.5 months to 30 years, with a median of 13 years. The etiology included 6 cases of Volkmann's contracture, all of which were flexion deformity of the 2nd to 5th fingers, accompanied by limitation of thumb dorsiflexion in 3 cases and limitation of wrist dorsiflexion in 3 cases; 3 cases of pseudo-Volkmann's contracture, including 2 cases of flexion deformity of middle, ring, and little fingers, and 1 case of flexion deformity of ring and little fingers; 8 cases of ulnar finger flexion contracture caused by forearm flexor disease or anatomical variations, all of which were flexion deformity of middle, ring, and little fingers. Operations such as slide of flexor and pronator teres origin, excision of abnormal fibrous cord and bony prominence, and release of entrapped muscle (tendon) were performed. Hand function was evaluated according to WANG Haihua's hand function rating standard or modified Buck-Gramcko classification standard, and muscle strength was evaluated according to British Medical Research Council (MRC) muscle strength rating standard. Results: All patients were followed up 1-10 years (median, 1.5 years). At last follow-up, 8 patients with contracture caused by forearm flexor disease or anatomical variations and 3 patients with pseudo-Volkmann's contracture achieved excellent hand function, with muscle strength of grade M5 in 6 cases and grade M4 in 5 cases. One patient with mild Volkmann's contracture and 3 patients with moderate Volkmann's contracture without severe nerve damage had excellent hand function in 2 cases and good in 2 cases, with muscle strength of grade M5 in 1 case and grade M4 in 3 cases. Two patients with moderate or severe Volkmann's contracture had poor hand function, with 1 case of muscle strength of grade M3 and 1 case of grade M2, which improved when compared with those before operation. The overall excellent and good rate of hand function and the proportion of patients with muscle strength of grade M4 and above were 88.2% (15/17), respectively. Conclusion: The finger flexion contracture caused by different etiology can be differentiated by analyzing the history, physical examination, radiographs, and intraoperative findings. After different surgical treatments, such as resection of contracture band, release of compressed muscle (tendon), and downward movement of flexor origin, most patients have a good outcome.

A Modern Day Timeline for In-Hospital Monitoring in Perfused, Pulseless Pediatric Supracondylar Humerus Fractures.

BACKGROUND: The perfused, pulseless supracondylar humerus fracture (ppSCHF) remains a consistent topic of discussion in the literature. Inpatient observation of these patients postoperatively for worsening vascular exam or compartment syndrome is frequently recommended but not well studied. The purpose of this study was to evaluate the postoperative complications in a cohort of ppSCHF patients and their timeline to discharge. METHODS: This study is a retrospective review of a prospectively maintained database of all operatively treated supracondylar humerus fractures from a tertiary pediatric hospital from 2013 to 2019. All patients without a palpable pulse were included. We excluded patients with <4 weeks follow-up. Demographic, operative, and postoperative data were collected, including time from presentation to operating room (OR), time from OR to discharge, and incidence of postoperative complications, including return to OR, compartment syndrome, new neurovascular deficits, and Volkmann contractures. The descriptive statistics were used to summarize the data. RESULTS: Among 1371 operatively treated supracondylar humerus fractures, 39 (2.8%) presented with a ppSCHF. Five (15%) had a signal on doppler ultrasound, whereas 34 (85%) had no signal. Thirty-seven (95%) patients had a Gartland type III fracture and 2 (5%) had type IV fractures. Twenty-two (56%) patients had a neurological deficit, of which 14 had an anterior interosseous nerve deficit. The average time to OR was 6.9 (range 2.2 to 15) hours; 6 (15%) required open reduction. At the time of discharge, 85% of patients had a palpable pulse and 13% had a dopplerable signal. Postoperatively, no patients were returned to the OR for any secondary procedures. The average length of stay after the operation was 25 (range 8.5 to 40) hours, with 92% of patients being discharged by 36 hours postoperatively. No patients developed compartment syndrome, new neurological deficits, or Volkmann contractures at a mean follow-up of 112 (range 34 to 310) days. CONCLUSIONS: In our study of 39 patients presenting with ppSCHF, no patient required an unexpected return to the OR, or developed post-treatment compartment syndrome, neurological deficits, or Volkmann contractures. The average time from OR to discharge for ppSCHF was 25 hours. LEVEL OF EVIDENCE: Level II.

Clinical and demographic profile Volkmann's ischemic contracture presenting in Tigray (Ethiopia).

OBJECTIVE: Volkmann's ischemic contracture (VIC) represents the outcome of a compartment syndrome, not adeguately managed during the acute phase. It is still to be found in the developing contries, while it is rarely present in the developed countries. In this report we refer on our african experiences on VIC, because we beleive might be useful for last generation of italian orthopaedics which rarely have a chance to see Volkmann's cases. MATHERIALS AND METHODS: AA report their 2-years experience of 16 patients aged 7 to 17, presenting various entities of Volkmann's in Tigrai. RESULTS: in all patients there has been an aceptable recovery of hand function, also although the difficulty to verify the outcomes because of the scarce overlapping of the clinical status and different operations. CONCLUSIONS: attention shall be drawn to the outcomes and a healthcare education is necessary in those villages where cures are entrusted to the so called "traditional doctors" who are nothing more than "bone-setters".

Congenital Contracture of the Ulnar Digits and Its Differentiation From Ischemic Contracture.

PURPOSE: To describe the clinical features, radiologic findings, differential diagnosis, and surgical treatment of a congenital flexion deformity of the middle, ring, and little fingers. The cause of the condition is the aberrant origin of the flexor digitorum profundus, leading to a congenital contracture of the ulnar digits. METHODS: We reviewed 8 patients with congenital contracture of the ulnar digits. The mean age at the time of surgery was 14 years. An examination revealed a flexion contracture of the middle, ring, and small fingers. Plain radiographs, 3-dimensional computed tomography, magnetic resonance imaging, and ultrasound were used to characterize bony and soft tissue pathology. Surgical treatments included resection of the aberrant origin and a muscle-sliding procedure. RESULTS: Bony prominence on the proximal ulna was seen in the plain radiographs and/or 3-dimensional computed tomography. A cord that extended from this bony prominence to the tendons of flexor digitorum profundus was revealed in the magnetic resonance imaging. The bony prominence and the cord were also seen using ultrasound. The median time of patient follow-up was 1.7 years. A simple resection of the tendinous origin only resulted in a release in 2 patients who were 4 years old. Older patients required a further muscle-sliding procedure. The average grip strength ratio on the contralateral side was 82%. CONCLUSIONS: Congenital contracture of the ulnar digits is a new congenital flexion deformity involving the middle, ring, and small fingers. Bony prominence on the proximal ulna is the key finding for establishing its diagnosis and distinguishing it from an ischemic contracture. We recommend treating this surgically at 12 years of age or older after the phase of rapid growth of the extremities. We recommend the resection of the aberrant origin, combined with a muscle-sliding procedure, as the treatment of choice, even for young patients. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic V.

Technical considerations and outcome of free functioning gracilis muscle transfer for finger flexion in patients with Volkmann's Ischemic Contracture.

INTRODUCTION: Severe Volkmann's Ischemic Contracture (VIC) is a reconstructive challenge for the surgeon because of the loss of entire flexor muscle mass and lack of powerful wrist extensors for restoration of finger flexion. In such cases, free functioning muscle transfer (FFMT) using gracilis is our choice. We herein summarize the technical considerations to achieve a successful outcome and report functional outcome achieved in our series. PATIENTS AND METHOD: Between 2007-2018, 22 patients of VIC underwent gracilis FFMT for restoration of finger flexion. FFMT was done as a second stage following an initial stage of neurolysis/excision of fibrotic flexor muscles/contracture release/flap cover in these patients. Cases were retrospectively reviewed and their functional outcome at a minimum of one-year follow up was analyzed. Follow-up duration ranged from 2-13 years (average-4 years). At the final follow up, the motor and sensory recovery was evaluated using the Medical Research Council Grading and their function using Disabilities of the Arm, Shoulder, and Hand (DASH) score. RESULTS: The average age at surgery ranged from 3-45 years (average-18.4 years). All the transferred muscles survived. Secondary procedures to further improve the hand function were done in nine patients. The motor recovery for finger flexion was graded as M2 in two, M3 in nine and M4 in 11 cases. These 20/22 patients who recovered M3/M4 finger flexion expressed high satisfaction with the operation while other two also felt that they were better after the surgery. DASH score was available for 13 patients and it averaged 13.21 (Range-1.8-34.5). Grip strength was available for 10/22 patients and it averaged 10.5 kg (range-0-21kg) amounting to 24% of the normal side. The sensory recovery was graded as S4 in two, S3 in 17 and S2 in three cases. CONCLUSION: Gracilis FFMT is a reliable option for restoration of finger flexion in patients with severe VIC. Outcome is better when done after an early preliminary stage of excision of fibrosed muscles and neurolysis which allows recovery of intrinsic function and sensation. FFMT is best carried out 3-6 months after the first stage with supple skin and good passive range of movement in the fingers.

[Retrograde muscle release method in treatment of mild to moderate ischemic muscle contracture of forearm].

OBJECTIVE: To investigate the effectiveness of retrograde muscle release in treatment of mild to moderate type ischemic muscle contracture of forearm classified by Tsuge. METHODS: Between March 2010 and September 2018, 11 patients with mild to moderate ischemic muscle contracture of forearm were treated with retrograde muscle release. There were 6 males and 5 females with an average age of 24 years (range, 16-29 years). According to Tsuge classification, 6 cases were mild type and 5 cases were moderate type. The interval between injury and operation was 9 months to 25 years, with a median of 17 years. The scar cords in the muscle of the middle one-third of the forearm was released firstly. If the standard of sufficient release was not reached, further releasing the scar cords in the muscle and the tense tendon structure in the proximal one-third of the forearm and the origins of the flexor muscles was necessary. If the standard was still not reached, the origins of the flexor muscles can be released and slid. The effectiveness was evaluated from six aspects of the range of motion of the hand and wrist, dexterity, grip strength, sensation, subjective function scores [quick-disability of the arm, shoulder, and hand questionnaire (Quick-DASH) and the patient-related wrist/hand evaluation (PRWHE)] and satisfaction. RESULTS: All the incisions healed by first intention. Eight patients were followed up 1-106 months (median, 13 months). The range of motion of the hand and wrist was significantly improved, the results were excellent in 3 cases, good in 3 cases, and fair in 2 cases, with an excellent and good rate of 75%. The patient's dexterity evaluation scored a perfect score of 12, which was close to the normal hand dexterity. At last follow-up, the grip strength on the affected side was 37.6%-95.5% of the contralateral side, with an average of 77.6%. Seven patients had normal sensation before and after operation, and the two-point discrimination of median nerve and ulnar nerve was 4-5 mm at last follow-up; 1 patient with forearm mechanical crush injury still felt numb after operation, and the two-point discrimination of median nerve and ulnar nerve was 8 mm and 7 mm, respectively. The Quick-DASH score was 0-15.9, with an average of 4.5, and the PRWHE score was 0-23.0, with an average of 6.6. All the patients were satisfied with the surgery and the effectiveness. CONCLUSION: A targeted retrograde muscle release method for mild to moderate type ischemic contracture of forearm can achieve satisfactory effectiveness.

[THE CHALLENGE OF DIAGNOSING RARE LIFE THREATENING SKIN LESIONS].

INTRODUCTION: Skin lesions seen after delivery are frequent and mostly shallow, without the need for special care or diagnosis challenge. In the following case, an infant was born at 35 weeks gestation, presented after the delivery with a well-demarcated, necrotic plaque over the right forearm with neurologic deficit. The differential diagnosis includes life-threatening reasons, therefore, emergent laboratory and imaging tests were held. Treatment was given after consulting a multidisciplinary team of experts, including antibiotic treatment, blood products and anticoagulation and physiotherapy treatment was started. Under this treatment, improvement was noticed but there was still a motor restriction. He was discharged home on his 24th day of life, with the working diagnosis of Congenital Volkmann Ischemic Contracture (CVIC). On his seventh week of life, he arrived to the emergency room with focal seizure resulting from an infarct seen on an MRI. He was diagnosed with cerebral palsy at the age of five months. In conclusion, Congenital Volkmann Ischemic Contracture is a rare diagnosis, however, awareness is of importance since fast treatment is crucial for future prognosis.

Nerve Lesions in Volkmann Ischemic Contracture.

Volkmann ischemic contracture (VIC) is a late sequela of acute compartment syndrome and consists of extensive muscle necrosis, fibrosis, contracture, and variable degrees of neural dysfunction. The outcome depends on successful restoration of muscle and neural function. The timing of surgery is often determined by the development of contractures and is delayed in the interest of observing some spontaneous recovery and infarct maturation. This period of observation may be detrimental to nerve function with gradual formation of scar tissue and worsening constrictive neuropathy. Early intervention appears to be more effective in preventing further nerve damage and restoring protective sensation. In this article, common features of compartment syndrome, frequently seen nerve lesions, and the effect of timing of surgical intervention on the outcome of VIC were reviewed in the light of the current basic and clinical science literature.

The case of missing skin: Congenital Volkmann ischemic contracture.

Congenital Volkmann ischemic contracture (CVIC) is an exceedingly rare neonatal compartment syndrome caused by intrauterine ischemia and external compression. It presents at birth with necrotic cutaneous lesions and neurologic impairment, typically in a distal upper extremity. Diagnosis and treatment are often delayed in neonates, leading to long-term neurologic sequelae. We present a rare case of CVIC in order to raise awareness of its presentation and management in hopes of improving outcomes.
